Floors on lags on adjustable legs. Installation of floor: Screws for installation of lag. Adjustable floors video

There are several ways to align floors under the finish finish. Among them are the main screed and regulated lags. Floor arrangement on adjustable lags is a less costly and fast process. About how to equip regulated floors on the lags, we will find out next.

Pros and cons of the adjustable floor on the lags

With the help of adjustable floors, it is possible to create a perfectly smooth black coating of the floor without additional alignment with cement compositions. As a system for alignment, a dense material is used as a flooring on which there are mechanisms for adjusting its height. It is with their help that the horizontal of the floor is ensured.

Adjustable lags are installed on a solid base. In some cases, the installation of the adjustable floor is necessary:

in the process of carrying out reconstruction work in the room, while a decrease in the floor level is reduced, it is not possible to establish a screed, as the weight of the floor and pressure on the foundation increases;
when performing redevelopment, it is possible to carry out all communications between the lags and the floor;
if the arrangement of the room is performed, which performs the function of the cinema, the floor and the wall in this case are highly soundproofed;
with a multi-level floor design.

In a ratio with the basic material for furnaceing, there are two options for coating:

adjustable floors on the lags;
plywood adjustable floors.

Among the main advantages of the regulated sex on the lags, we note:

1. Compared to concrete floors, the adjustable floor has a smaller weight, because of this, it does not load the building structure and the foundation. Such a floor with ease withstand any overlaps is particularly relevant for cottages and wooden houses.

2. The adjustable floor device is a dry finish option for the execution of which you do not need to use wet solutions, and cleanliness is saved indoors.

3. With the help of the adjustable floor, the lags can align not only small tubercles, but also remove significant differences in height.

4. Installation work is carried out quite quickly than in alignment with a concrete solution. You can align the floor in the room in one day, while you do not need to wait an extra time for the drying of the floor. Immediately after alignment, further work is carried out.

5. Between the main floor and lags is underground, within which communications is installed.

6. In addition, heat and sound insulation are installed in this air layer. Thus, comfort improves from the use of such a floor indoors.

However, regulated floors also have their drawbacks. This is primarily a creaking, which is prevented only at the stages of installation work. First of all, dust should not remain at the overlap, the vacuum cleaner is used for these purposes. All fasteners are clogged to the end, wooden elements must fit tightly to each other. Thus, it is possible to prevent loosening the racks.

As a result, after a certain time, the wooden surfaces begin to creak. This comes from the fact that the tree under the influence of moisture expands and narrows by changing the form. Technologically properly performed installation of the lag allows preventing the appearance of a screens. Another lack of such a gender is that with a significant lift of the lag, the floor publishes sounds, especially when walking on heels. In order to avoid such a phenomenon between lags, the heat insulating plate is placed.

The process of selecting an adjustable floor or concrete screed should be based on the individual features of the premises in which work is carried out. Choosing adjustable laugs pay attention to such advantages as the presence of a ventilation gap and space for the installation of communications, the speed of work, the lack of need waiting for the drying of the screed, etc. In order to obtain high-quality coating, it is necessary first of all to follow the technological parameters of the arrangement of the adjustable floor. Studying about the field on adjustable lags reviews, we draw conclusions that this type of flooring is an excellent alternative to the concrete tie.

Among the main functional features of regulatory devices, we note:

performing a function of a reliable support in a lag or plywood system;
work as a guide element when mounting fasteners;
rapid change in the height of the floor in the horizontal plane.

The performance technology allows you to set adjustable lags with your own hands without attracting specialists or an additional tool.

Device adjustable floor lag - construction technologies

Plastic support bolts are used to adjust the floor, which have external thread and dowel-nails. Plastic bolts are installed or in the slab or inward the lag.

After installing a dry screed, the bolts and leveling structural elements on the floor are fixed. For this, a dowel of nails are installed inside the bolt. Adjustable floors differ from ordinary in that they have a special screw system, which allows you to quickly adjust the height of the floor. In addition, the screw mechanisms perform the function of the guides for the dowel-nail. Dowel-nails have different sizes, the choice of which is determined by the power of leveling structures and floor area. Dobanimer is used to climb a dowel of nails.

Dowel nails are set if the floor is mounted on a concrete base. For fixing the floor on a wooden coating, it is sufficient to use the screws with a galvanized coating.

Simplified bolts for adjustable floor contain in its composition steel rod, outdoor thread. The lower part of them contains elements for fixing on the surface of the base floor. The upper part of the fastener is characterized by the presence of elements regulating fixation. Another option is the use of steel P-shaped parts. They are fixed on the floor with screws, however, installation work in this case is carried out for quite a long time and require additional physical efforts to conduct them.

The support bolts of the sleeve type are mounted or on the surface of the lag or on the plates. Therefore, it is customary to allocate two technologies for installation of an adjustable floor. The selection of one or another variant is determined by the planned height of draft floors:

if the floor rises more than 50 mm, then it is enough to use standard lag;
if the size of the floor lifting is less, then it is enough to use leveling plates.

In any case, with the help of special adjusting supports, a smooth surface is created on the floor. However, the differences consist in the length of the support bolts. In addition, the holes under the screws are located in various schemes in the first and in the second case.

Choosing adjustable supports of the lag of the floor, pay attention to the height of the resulting coating. In this case, consider the height of the available floor, add communication systems to it, which will be in the underground space. Further, decide on the option to arrange the system of adjustable lag.

Make a project of the room, write it all its size on a specific scale. With the help of such simple drawings, it is possible to quickly calculate the amount of material for the installation of the floor. Note that the perimeter of the room should be the ventilation gap, the size of 10 mm. Lay on the drawing of the plate, the factory configuration in the desired order. Mark on each plate its number, decide on the steps of drilling holes under fasteners, for their definition, consider the material to perform the finishing floor finish.

In order to form the perfect dry type screed for laying tiles or linoleum, the interval between the fasteners should be at least 300 mm. The maximum interval for fixing fasteners is half the meter. Note that the increase in this value leads to a non-dense fitting plates to the floor, therefore, after a while, the appearance of a violep may occur.

If after installing the adjustable lag, the milking floor will be formed, then the plywood on the aligned floorings is not installed. The board in this case is fixed on the bar.

Technology for the construction of adjustable laghams

We offer to familiarize yourself with the technology of adjustable floor arrangement on lags with plastic sleeves. To mount plastic bushings, stick to such rules:

in the process of drilling the first hole, retreat from the end part 100 mm;
the remains of 10 cm from each edge are divided equally under fixing fasteners;
do not forget to leave the ventilation and compensation gap between the stove and the wall;
set lags in a ratio with a previously defined step of fixing;
lags that are in the ranks are set in such a way that each part of plywood relied on the surface of the bar.

Among the advantages of using this method of laying lag, we note:

the creation of a warm and comfortable atmosphere indoors;
high sexual strength and resistance before mechanical effects;
duration of operation and simplicity of caring for wooden structures;
environmental Safety;
ease of installation work;
available cost.

In order for the floor of the adjustable lag to serve as longer as possible, before laying, all wooden structures are treated with antiseptic compositions and other protective impregnations.

As a floor coating material, boards are most often used. At the same time, the most comfortable - the floor boards of the t-shirt type. They differ in the presence of ships-groove compounds that form a solid and durable coating.

In the process of performing installation work, the presence of a tool is required:

hammer;
electric drill and screwdriver;
ax and hammer;
level;
electric jigsaw.

Among the materials will require lags, floorboard, insulation, special materials for the substrate, fasteners.

At the preparatory stage on the installation of the wooden floor of regulated lags, the basis for work is prepared. First of all, the old base is cleaned of dust and garbage. In the process of laying the floor, it is not necessary to level the base, this process is performed by adjustable lags. With the presence of large picking on the basis of concrete, cover them.

Next, you should cut the lags of a certain size. For these purposes, an electrolovka is used. The size of the floor lag is 5x5 or 6x4 cm. Initially, the old coating is covered with a layer of rubberoid, it will provide reliable floorproofing of the floor.

the thickness of the insulation installed on the floor;
thickness of the floorboards themselves.

The optimal installation interval of lag on the floor is half the meter. To fix the lag use an anchor for adjustable floor on lags.

We offer to familiarize yourself with the detailed instructions for arranging the adjustable floor on the lags:

1. On Bruke, mark the places for fixing fasteners. Next, with the help of a feather drill, arrange holes for support sleeves. They are fixed on the surface with self-tapping screws. Adjusting the height of the floor is performed using the twisting of the extreme bolts.

2. Lag, on which there are bushings are installed on the intended place. With the help of internal points, marking places for fixing lag.

3. In order to make a hole, use the perforator. The depth of the opening should not exceed five centimeters. Install the lag and fix it with the fasteners of the bolts.

4. At the extreme plots of lags with the help of a bipper, install a dowel nails. The ultimate driving is made after floor alignment. Ordinary dowel nails are installed after installing all the lags and their alignment.

5. The arrangement and height of the lag adjusts the hex screwdriver. To do this, install it in two extreme bolts. To control the action, use the level.

6. After determining the ideal position of the lag, fix the last dowel-nails, install all the other fasteners.

7. If there are parts that come above the surface of the floor, use the chisel to remove them.

Thus, the installation of each element of the floor coating is made. After that, plywood or floorboard is installed on the lags. The interval between the fasteners plywood is a maximum of 15 cm. This method allows you to log the installation reliable and technologically perfect finish to perform further work on the installation of finishing.

Not so long ago, in the process of laying the lag on a draft base for bars, plywood pieces were laid or wooden stakes. Thus, it was possible to protect the tree from the impact of moisture and align the rough base horizontally. But over time, the substrate has succumbed and has come into disrepair, which affected the horizontal coating. In the article, we will look at modern ways of fastening the lag to various types of base.

Features of applying fasteners

In the process of fastening the lag to the wooden basis, there are no special problems. To do this, you can use long screws or corners. And what about the concrete base, in which the screws will not be easy to screw? To strengthen the lags on the concrete, you need to use special types of fasteners. The choice of fasteners required for the installation of bars to the concrete floor depends on such factors:

Horizontal surface. Depending on whether additional alignment is required or not, you can use adjustable or unregulated fasteners in height;
The level of humidity of the base. If the lags are mounted on a ribbon foundation, they will have to lay almost on the ground. To fix the bars, use mostly brick columns that protect the tree from moisture exposure by playing the role of an insulating lining;
The degree of load on the base. It is possible to strengthen the lags on the floor using both self-tapping screws, and brackets. However, in the case of intensive exploitation of the floor, the self-tapping screws may not withstand the load. That is why the type of fastener is chosen in accordance with the alleged load on the floor covering;
Heights underground. Wooden floors are prone to accumulation of condensate under coating and rotting. To protect the wooden base from rotting and deformation, experts recommend using high lag supports. They form under the bars underground, in which the air can freely circulate, which warns the formation of condensate.

In order to correctly fasten the bars on the draft floor, you need to understand not only in the methods of fastening, but also in the varieties of fasteners. An adequate choice of support will allow to extend the period of service not only rough, but also a finite coating.

Types of fasteners

As noted, the attachment of the bars to the floor involves the use of only two types of fasteners:

Simple - static supports that do not allow to vary the height of the installation of wooden elements;
Adjustable - contain screw structures, thanks to which the fasteners can be set in height, which allows to achieve the maximum horizontal base.

What types of fasteners can be used to fix bars on the floor?

reference columns;
self-tapping screw;
corners;
brackets;
anchor.

To understand the essence and features of the application of the above details, consider each of the categories in more detail.

Selfless

Self-tapping screws are simple fasteners that are used to finish a wooden, but not concrete floor. Quite long rods with outdoor thread are capable of attaching beams to wooden floors, but only in case of accounting for the following nuances:

Before fastener and in the bars themselves, and at the base it is necessary to make through holes;
In the end-to-end hole it is necessary to insert a dowel and only after that screwed the screws;
So that the lags did not break off from the wooden base, the self-tapping screws are fixed in a step of 40-60 mm;
The length of the self-press is determined by the thickness of the bar, it is desirable that in the process of screwing the "tail" of the screw leaked into the base at least 5 cm.

The affordable price of fasteners made them very popular in the circle of home masters. But to achieve the desired result, in the process of installing the lag, it is necessary to take into account the above moments.

Anchor

Anchor - combined with self-fastening element mounted, which, in contrast to the dowels, not only easily fixed in the ground, but also keeps the weight of the heavy structures. Anchor refers to the number of durable and reliable types of fasteners, which are used to attach lag to any foundation (tape, pile). If you discard all the "sublimation", the anchor is all the same dowel, but with a more powerful basis.

In the process of fixing the lag, the anchor is mounted in about the same way as the self-sufficiency:

In the bars make through holes, after which symmetrical, but not only through holes are made at the base;
To disguise the bolt's hat, the bars must first be translated;
Since the anchor is very strong and able to maintain heavy structures on itself, no more than 4 fasteners will be required to attach one bar;
In the obtained holes are inserted by the shut-off parts of the anchors, through which bolts are screwed;
When flashing lags, it is necessary that the bolts can deepen into the base of about 6 cm.

To strengthen the bars on a draft basis, experts recommend using anchor with a diameter of 8 to 10 mm. Metal rods of such thickness with ease withstand very heavy loads.

Brackets

Brackets are console supports that serve as a static base for fastening parts in the vertical plane. As a rule, they are used in the process of fastening the lag to the support pillars. Cross-shaped (x-shaped) curved parts have fixed sash in which the timber is laid. The price of such products is significantly higher than in the case of self-drawing, however, the range of possibilities in such fasteners is much larger.

Very often in the process of laying a draft floor on a ribbon foundation, brick columns are installed. They play the role of supports and protect the tree from moisture exposure. Since with the time of lag I remember, without additional fasteners, it can be deformed. The only convenient and reliable way to fasten the bars on supports is the use of brackets.

Support columns

Stakes for lag are supporting structures that are harvested from bricks with a cross-section of 1-2 bricks. In fact, these elements perform the task of the "invisible" lining, preventing the impact of dampness on the tree. The columns are mounted in the case of styling the draft base on a tape base or concrete. Since the level of groundwater can constantly change to protect the lags from water, specially form underground.

To correctly strengthen the lags and build columns, such moments should be taken into account:

Supports are undesirable to erect from hygroscopic materials - artificial stone or silicate brick;
You can not install columns on bulk soils that can be blurred by water;
Supports that will be installed on the incomprehensive ground must be made above the soil level in the underground at least 2-3 rows of masonry;
Pillar laying is desirable to do with a single-row dressing, observing a single level of height for all supports;
It is possible to mount the bars to the supports with the help of brackets, anchors or special corners with self-drawing on concrete.

Corners

Corners - galvanized metal parts with two planes, located orthogonally relative to each other. The price of such fasteners is largely determined by the dimensions of the elements themselves, as well as their thickness. From the mentioned parameters directly depends on the degree of strength of the corners. In the process of fixing the lag, it is advisable to pay attention to such nuances.

Currently, the main criteria that are presented by sexual grounds are strength and reliability, since it is precisely from them that the quality of laying of the outdoor finishing material depends. In order for the floor to be even, experts are advised to give preference to adjustable structures that are constructed by lags.

What you need to know about adjustable floors

as adjusting elements, hollow wear-resistant polymer bolts are used;
the adjustable base is divided into two types: on the plates and on lags;
if Paneur is used as the base of the adjustable gender, the bolts should be mounted on the bottom of the sheets;
when laying isolation between the concrete base and the adjustable floor on the inner surface of the lag, metal locksters should be fastened;
lags should be located apart from each other in 25-45 centimeters, and the step under the tile should be small;
if there are no hollow polymer bolts, then the fastening mechanism can be made from a clogged anchor with thread. In this case, wooden lags or plywood sheets are clamped on the anchor pin with the washers and nuts;
adjustable floors with proper installation can serve at least 35 years.

Device adjustable floors

Adjustable flooring on lags is a floor device located on special boards, under which the underground space is located. Due to this, the floor surface does not need additional alignment with a concrete screed.

The threaded anchor for adjustable floor is fixed to the base, which can be wooden, concrete or soil. The height of the floor is adjusted due to the possibility of the retainer rotate around its axis.

Anchors are attached to the base depending on the type of draft floor:

mounting to the concrete slab occurs with polypropylene needle dowels;
fastening to a wooden basis occurs with the help of screws;
mounting to the concrete screed occurs with the help of a dowel-nail.

Anchor design performs the following functions:

adjusts the height of the floor;
provides a load separation;
strengthens the strength of the bonding unit with adjustable.

Advantages of adjustable floors

Adjustable floors have a large amount of advantages, among which you can allocate:

the possibility of using as the basis for any finishing material;
the possibility of installation on its own, since work is quite simple and do not cause special difficulties;
ease of construction, so that it can be used when arranged loggia or balconies;
the possibility of laying communications or the insulation layer in space between the flooring and base;
installation of adjustable floor on lags is a sufficiently dry and clean type of work, which allows not to blur the walls during operation;
wooden floors are able to cope well with differentials exceeding 15 centimeters;
the cost of adjustable floors compared to the concrete screed is more accessible, which makes them more popular;
thanks to modern technologies, the possibility of arranging the perfectly smooth floor without creating a violep.

Adjustable floors do it yourself

Adjustable flooring floors

To begin with, it is necessary to fasten the lags in a step of 30-50 centimeters, with the help of screw-string bolts. The lags are then aligned according to the level, for which the rack bolts rotate along the axis using a special key. At the end of the lags, the Phaneur is fired by a double layer, while the thickness of each sheet should be at least 12 millimeters. In the case will continue to lay ceramic tiles for laying the upper layer need to use water-resistant plywood about 10-12 millimeters thick.

During the installation of adjustable plywood using a feather drill in a plywood, 16 through holes are made. Then plastic sleeves are inserted into them, in which the bolt racks are screwed. After that, you can start to align sheets, rotating the bolt racks, fixed to the base of the dowels.

Attention ! To install the floor, it is necessary to use lags from durable wood with humidity from 12 to 14%. They should not have cracks or bitch, mold traces or rodent lesions. Lag length is usually 2 meters, and the cross section is 4.5 per 4.5 centimeters. Before starting work, the material should be treated with special protective compositions. Underground should be enough air for ventilation.

The main advantage of such a gender is that the possibility of arranging the perfectly smooth and even draft gender on an unprepared base. Due to this, in the future you can use almost any floor covering.

Horizon level exhibition with adjustable lag

Due to the construction of the design of this type, you can disguise any systems (ventilation, heating, electrical and so on). If the "Warm floor" system will occur in the room, its installation, made on such a design, will significantly reduce heat loss through the floor and, thereby saving electricity.

Despite the fact that such an adjustable design is characterized by a sufficiently low weight, it can withstand heavy loads that can reach up to 2500 kilograms per square meter. Thanks to this, adjustable floors have found their use not only with the arrangement of residential rooms, but also warehouses, sports halls and other premises.

At home with such a design of the floor can be energized even on such soils, in which large loads on the foundation are categorically prohibited. If the floor can not be raised too high, then you can use a special design on adjustable plywood, at which the rise will reach only three centimeters.

The technology of its installation is almost no different from the installation of Lag. The main difference is that instead of lag, naturally, plywood sheets are used.

Plywood - material used not only in home everyday, but also under aircraft enterprise, shipbuilding, furniture manufacturing and many other industries. With the help of plywood, you can easily replace the damaged section of the floor, because it is perfectly combined with flooring from linoleum, laminate, carpet and parquet. But so that there is no misunderstanding, you need to know how to properly strip Phaneru.

Advantages of plywood in front of other materials:

material strength is the same in all its directions;
sheets have sufficiently large sizes;
education of through cracks is completely excluded;
plywood is easily bent;
the transportation of the material does not cause any difficulties;
it has a slight weight, but high strength;
plywood is characterized by high quality grinding and solid surface;
water consumption material and does not smell.

Adjustable plywood is perfect in cases where the floor has a skewer exceeding a mark of 15 centimeters, or communications pass on it.

Attention ! When adjusting the floor by lags, the height of the room usually becomes below about 7-8 centimeters, so it is recommended to use in rooms with high ceilings. In turn, when laying floors on an adjustable plywood, the floor rises not more than 3 centimeters, so the second method is considered more efficient.

when choosing materials for alignmenting floors, it is necessary to look for a timber and a phaneer as high as possible, since this show significantly affects the result of all work as a whole;
for easy installation, it is recommended to purchase a laser level that will make more accurate results;
plates of overlapping and base must be as strong as possible, do not crumble and not crumble;
do not forget about the need for ventilation of coatings;
so that the floors do not creak, in the installation process, all surfaces should be cleaned from dust (as soon as the holes are drilled, and the bolts are screwed, surfaces thoroughly vacuuming). In addition, the dowel-nails should be navigated as much as possible so that the racks are not loosened;

When using this method, the lags are replaced by bushings, within which the thread is located (special holes are drilled in the plywood). 6 plastic bolts are screwed into the sleeve, which in the future it is necessary to attach to the base with a dowel. To align adjustable Phaneur to use the key.

First, it is necessary to thoroughly align the first layer of plywood, after which it is necessary to install the next layer and fasten it with self-stairs. Before laying the second layer, it is necessary to carefully overlap the joints of the previous one, which will avoid the formation of seams. Thanks to the actions done, the floor surface will become smooth and smooth.

It knows that in order to align the floor level in the apartment there are several of the most common ways. And one of them is to use adjustable floors. The use of concrete screed gradually loses its popularity. These works require significant efforts, and also assume the presence of dampness and dirt. Especially for the installation of adjustable floors, it will take a lot less time.

One worker per day can independently put the floors on the square up to 20 square meters. m. Then we will tell more in more detail about the advantages, disadvantages and features of the assembly of adjustable floors.

Design features

To understand what regulated floors should be familiar with their principle of action. Studs rotate around their axis, which allows you to adjust the floor level horizontally. By the same principle, floors work on plates, which are also moved due to rotation. This allows you to set the floor as accurately as possible. You can align the floor horizon almost perfect.

Such structures will not become exhausted under weight or "play". You can install them on any available surfaces. On each floor you can impose several layers of coating (plywood).

Such floors will become an excellent solution for sports halls, clubs, office premises, and so on. Due to the amplification of carrying spills, the load indicator (up to 2 tons per 1 sq. M. m) can be increased. The service life of adjustable floors is up to 15 years.

Features of use

Adjustable floors most often apply:

At stations and rooms for server location;
Under the final finish in the maximum deadlines;
In the houses of new buildings;
In houses of old buildings for overhaul or reconstruction;
To increase the level of sex for a sufficient level (especially when additional pressure on the main floor is undesirable);
When installing multi-level floors;
To carry out under the base of the floor of all sorts of communications.

If you need to align or lift the floors to a significant level, the use of adjustable floors will become an excellent solution. After all, it will take a month for laying a concrete screed, while with adjustable floors you can handle over one or two days.

Also, the use of such systems will be useful in homes, where under the floor specially left a distance of up to 15 cm for laying communications or insulation. Not all designs can withstand the load of such a layer of concrete. But the use of adjustable floors will help you raise the coating level up to 20 cm.

You can also successfully, for example, transfer to the plumbing (toilet or bathroom) and hide bulky communications not under a thick layer of solution, but under the floor where they will remain available at any time.

Especially popular use of such systems for country houses or cottages. So you are given the opportunity to hide all communications in one place, where they will be reliably protected from exposure and are available at the earliest.

Pros and cons

As with any such systems, there are also its advantages and disadvantages.

Benefits:

One worker can install the adjustable floor during one working day;
The system of adjustable floors is lightweight in itself, so it will not be able to additionally put pressure on the main floor;
International testing confirm the quality, strength and durability of such systems;
Using adjustable floors, you can additionally insulate the room from sound outside;
You are given the opportunity to use the floor to hide all communications, which is a plus not only from aesthetic point of view, but also safely collects them in one place;
Maximum accuracy when placing horizontal floor level;
Various levels that can be used in parallel (up to 20 cm);
Materials that are used for manufacture are tested for purity;
There is an opportunity to quickly correct the irregularities of the floor, even if there is a 10-15 cm inconsistency;

Such a system is distinguished by durability.

Disadvantages:

Over time adjustable. To avoid this, at the installation stage, it is necessary to remove all dust and dirt after drilling holes and clogs of dowels. It is best to use a vacuum cleaner for this. Also thoroughly clean the first surface of the floor before laying the second layer. Controls so that all the dowels and nails are clogged to the end. It will not allow the design to fall out. It is also necessary to take into account that the tree is a natural material that breathes and is able to deform under the influence of moisture or gravity. Over time, the symbols, one way or another, will manifest;
If you raise the floor level for a long distance, then when walking on it will be heated. For example, the sound from women's heels will remind a blow to the drum. Installation of additional sound insulation will help correct the situation.

All your work depends on the quality of the materials used. Take their choice with special attention. High-quality bar and plywood will get rid of you from the need to dismantle the floor in the future.

For maximum accuracy when setting the floor level, use a laser level.

Take care to ensure proper ventilation under the floor covering.

Types of adjustable floors

Depending on the type of design, adjustable floors are divided into two groups:

plates;
lags.

With the help of adjustable plates, you can lift the floor for a distance of no more than 3 cm. This is a bit, but enough to carry out the necessary communications: telephone, internet and so on. You can also pave heat-insulating and sound insulation materials under such floors.

Such structures are sheets of thick plywood (you can use a few of its layers). Special sleeves are inserted into it. The peculiarity of these sleeves is that they already provide a special internal thread. It has an anchor for an adjustable floor, which will serve as a level regulator. Then the whole design is installed on the base and is fixed by dowels.

As already mentioned, the difference between such a system is that the adjustment of the floor level occurs directly through the holes in the stove (from plywood or any other suitable material).

To assemble the floor based on adjustable slabs, it is enough to adhere to our tips:

Drill holes in plywood sheet;
Then insert the sleeves in them, on which the thread from the inside is pre-screwed;
Insert special bolts into the sleeve, which will adjust the plate level;
Fix the bolts to the base;
Turn the bolts until the ideal flat floor plane do not achieve;
After that, the remains of the bolts that look out over the surface of the plates must be cut off with a grinder;
The final stage of the assembly will be the laying of the next layer of plywood, which will hide traces of bolts.

Note that when laying a new floor layer, its seams should not coincide with the seams of the previous one, because the design will not be durable.

Adjustable lags for the floor today are the best alternative. When using such a design, the floor will be raised at least 5 cm. This distance can be successfully used to insulate the room from sound or smells, as well as for laying all the basic communications of the apartment or at home.

Such structures are highlighted by simplicity and speed of assembly, as well as reliability and durability. Lag is equipped with special sockets for installing bolts. It is fixed to a special base with a dowel. To change the floor level, it is enough to rotate the bolt in the desired direction. After complete alignment of the plane of the floor, the coating is superimposed on them.

Such floors are often used in the buildings of the new construction of high comfort, in which the gasket of all major communications is made under the floor.

The main advantage of such systems is their robust fixation to a wooden or concrete basis. Other materials can be used as a base. For example, a thread anchor can be installed on concrete slabs, hollow inside, wooden bars with self-tapping screws, as well as brick surfaces with a concrete tie with special mounts or to the wooden floor.

To properly assemble such a design, check out our instructions:

In the nest in the lag, special racks (bolts) are installed;
Now decompose lags around the perimeter of the room and inside it. Here it is necessary to take into account the required strength of the design to a sacking, which depends on the type of floor coating used. For example, the distance between the lags should be about half a meter. If you use floor tiles, then keep the distance to no more than 30 cm. To ensure the necessary air circulation, step from the walls one centimeter;
Then through the holes provided in the lags, drill in the floor for installing bolts. Their depth should not exceed 4 cm;
Next, you have to set the floor covering at the required level. Note that the difference in the parties should not exceed 1 mm. To regulate, use a special key that turn bolts;
After placing the floor, hammer the protruding parts of the dowels or cut them with a grinder or chisel.

Next, the installation of the floor covering is performed. To begin with, use two layers of waterproof plywood. The first layer is secure with self-tapping screws straight to lags. The following layer of plywood should be installed with a slight deviation from the first so that the joints do not coincide. In the case of using floor tiles, waterproof drywall is better used as the second layer.

To hide the irregularities and gaps between the floor coating and the walls, use the plinth. Specialists in some cases are recommended to establish them after all finishing works.

As you can see, the adjustable floor on the hairpins or on the plates is a rather successful alternative to a conventional concrete tie. Moreover, it is not necessary to have special construction skills to install such a design. It is enough just to be patient and do everything according to the instructions. If you have ever come across the problem of installing such systems, share your comments under this article.

Make adjustable floors can be instead of a concrete screed. The main thing is to learn all the features of such structures and their installation.

If you ever spent overhaul, you know how difficult it is to level the floor level. The solution may be the installation of an adjustable floor. This is an affordable alternative to the tie of concrete, the creation of which will not require tremendous effort and will not take much time.

What is adjustable gender?

At the same time, floor coverings were laid on the lags and a concrete tie. However, today more and more builders prefers adjustable floors. We are talking about a draft field, made in the form of plywood flooring or lag. The height of the surface can be monitored using special rack blocks.

The essence of the design is to use 18 millimeter plywood sheets or lag from wood. Support of thread or other serve bolts made of wear-resistant plastic. Turning around the axis, the bolts change the height of plywood or lag, giving the opportunity with accuracy to align the draft floors. After the design is leveling, the bolts are securely fixed on the base with a dowel-nail.

The base may be: beam (wooden) or concrete (with a screed, hollow, monolithic). On the lags, as a rule, there are moisture-resistant plywood. Next - any floor covering (, parquet board, parquet, etc.). In order to better understand what is adjustable floors from plywood or on the lags, you should watch photos and videos on our website.

Use the design is suitable in the following cases:

It is necessary to align the floor covering under the final finish in the minimum time;
It is necessary to raise or align the floors to a substantial height (the concrete screed will require a month for laying. Adjustable floor can be mounted in a couple of days);
It is necessary to leave a place for communication systems;
It is planned to create a multi-level floor;
It is necessary to perform a new floor in the old building during overhaul or create it in a new building.

Views and features

Lagi

If you will use adjustable supports and lags to create a draft floor, the design will be able to rise at least 5 cm. Such a height will allow you to find a place for both additional sound and thermal insulation and for any communication systems.

Collect the floor on adjustable lags with your own hands can be easily. Lags have technological holes in which the bolts will need to screw. The lags themselves are mounted on the basis and fixed on it using long screws with a dowel previously scored in them. After that, it is necessary to align lags by level, tuning the rack bolts. And then the first floor covering.

Choose adjustable lags for the floor, and you can build a durable and durable design, even if you work alone.

Plates

If for some reason you do not follow the adjustable floors on the lags, you can create a design from the plates. The surface will rise by 3 cm minimum.

IMPORTANT! In the case of adjustable plywood, emptiness will be enough for different wires, not enough for large communications.

In the role of plates there are several plywood sheets. In the lower, the technical openings for the sleeve with internal thread are performed. The legs of the bolts on one side are fixed on the base of the floor on the self-tapping screw, on the other, they screw into the sleeve. To equalize the surface you need to rotate the bolts.

Arguments against"

In adjustable floors, there are several drawbacks that you need to know before making a decision on the installation:

The floor will begin to creak. Even if each anchor and each rink system will be high-class, this problem is not easy to avoid. Only a competent approach will cope with it: when installing, get rid of all the dust and dirt remaining after clogging the dowels and drill holes. Before laying the second layer, clean the first one. Each nail must be clogged to the maximum. Unfortunately, wood in any case will be deformed from gravity or humidity in the premises. To creak such a floor will begin without fail;
Having lifted the floor to a big height, you will hear further the additional sounds. For example, women's heels will be heard as blows on the drum. Additional sound insulation is needed.

Arguments for"

List of advantages longer:

Ease of installation. You can install the design with your own hands during the day;
Adjustable floor has durability and reliability;
The design allows additional sound insulation of the premises outside;
All communications can be safe and reliably hidden from prying eyes in one place;
Establish the horizontal level of the floor surface can be most accurate;
The system is created from environmentally friendly materials;
Even if the floor does not correspond to 15 cm correct the situation in short time.

Choosing materials

We have already said that the adjustable floor is created in two stages:

Installation of lag with movable supports;
Floor arrangement.

What sheets to choose? It depends on how the facial coverage will be. If you want to store a parquet or lay laminated panels, use the moisture resistant plywood. If the tile or linoleum, choose moisture-resistant plasterboard sheets.

For wooden floor, experts advise to take a t-shirt and smooth board. The supports can be different, but their difference from each other consists only in the method of adjusting the height of the flooring - the floors on the corners or on the hairpins.
