Do-it-yourself door frame installation step-by-step instructions. How to install doors correctly: step by step instructions. Choice of door frame material

Key question in the process self-arrangement doorway - how to install door frame do it yourself. With the right skill, this work is done fairly quickly. If you are doing this for the first time, first you need to familiarize yourself in more detail with the device of this design and its main types.

For self-assembly door frame, you need to know all the nuances of this process

Types of boxes

What is a door frame and why is it so important to install it correctly in the opening? The door frame is a supporting element of the door structure that holds the leaf and consists of two vertical and one horizontal strip with projections. It is fixed directly in the opening itself, adjacent to the wall. Such a structure forms a smooth portal and ensures the reliability of the door fastening. Hinges are cut into one part of the frame, onto which the canvas is hung. On the opposite side, a hole is drilled for the lock and the counter plate is fixed.

Since the position of the curtain depends on this element, correctly placing the door with the frame is a priority during installation. In the presence of the slightest skew, the parts will be overwritten and impede the free movement of the door. If you do not calculate the weight of the canvas in relation to the strength of the box, more serious problems may arise.

What types of door frames are there? A classification can be made according to several criteria. For example, assembly might be the determining factor. In this case, the most popular boxes are:

Straight- the elements are connected perpendicularly. Most reliable way- "thorn-groove".
Diagonal- the edges of the planks are cut at an angle of 45 degrees.

Two types of connection of door frame parts

Also, the types of door frames are distinguished by the material of manufacture:

tree,
plastic,
metal.

In apartments for entrance doors mostly use metal constructions, and for balcony systems - metal-plastic boxes.

Preparatory work

Before installing a new door frame, it is necessary to check the presence of all necessary tools and supporting materials... Depending on the material of the product, their list may vary. In most cases, do-it-yourself door frame installation is done using the following tools:

roulette,
corner,
pencil,
level and plumb line,
wooden wedges,
auxiliary bars,
spacers,
nails, screws and screws,
screwdriver,
jigsaw, hacksaw or file,
polyurethane foam,
chisel,
miter box.

The necessary set of tools for installing the door frame

Do-it-yourself installation of a new door frame begins with surface preparation. First you need to free the opening from old door and frames. In case of significant irregularities or deviations from the dimensions of the new box, the walls must be adjusted. For this, plaster is used, and the protrusions are cut off with a grinder.

In order to correctly install a new box, it is recommended to make it for the specific dimensions of a previously prepared opening.

Before you start assembling the door with the frame, clear the floor surface, since the preliminary assembly must be done in a horizontal plane. Installation takes place in several stages. Let's take a look at each step in order.

Assembly

At the second stage, you need to correctly adjust the dimensions of the parts. To do this, you need to measure the height of each side and the width of the opening. For a visual assessment of the situation, you can put the planks against the wall and mark the places where you need to shorten them.

If the installation of the box is carried out by means of a diagonal connection, you need to cut the edges of the strips. Since it is quite difficult to correctly determine the degree and saw down the door frame, be sure to use a miter box, then the assembly will not be difficult.

Before putting the door frame into the opening, it is necessary to check its dimensions with the dimensions of the canvas. To do this, you need to fix all the parts on the floor.

Since the door frame can be assembled as correctly as possible only in a horizontal position, lay the slats and the canvas on the floor. The assembly begins with an assessment of the coincidence of dimensions. To do this, lay out the details around the perimeter of the door. If everything fits together, you can start bonding the elements.

Door frame assembly requires precision and care

How to assemble the door frame depends on the type of connection. If a straight line is used, you need to join the protrusions with the grooves. With a simple diagonal, the planks are connected using nails. If you know how to correctly and quickly assemble a door frame with your own hands, there should be no problems with the rest of the work. Check the correctness of the dimensions and the presence of a small clearance for the free movement of the blade. Only then can the installation of the box be carried out directly.

Installation

After preliminary control, you can put the box in place. Installation is carried out with bolts and foam.

Wedges are used to adjust the height of the door frame

How to properly install a new door frame with your own hands:

So that in the future you can quickly it is recommended to cut the hinges into the frame in advance.
Then you need to carefully put U-shaped design in the opening.
Use bolts and wooden blocks to secure it in position.
Insert pegs into the gap between the wall and the frame and adjust the level.
After the position has been fixed, you can foam the gaps between the wall and the planks. In this case, it is necessary to secure the structure with spacers, since the elements may be displaced. Simply foaming a door frame is not allowed by technology.
When dry, remove the spacers.

The main stages of door frame installation

Final finishing

The assembly of the door frame does not end there. If you do it yourself, you need to see it through to the end. This involves removing excess fixation materials and decoration opening. First you need to cut off the protruding pieces of polyurethane foam and wooden pegs.

Please note: if the box does not cover the entire thickness of the wall, additional fittings must be supplied.

Opening without box

Installation of the box is not necessary in every case. For example, you can do without it if you put sliding system or an accordion door. But how do you put a door without a box? All parts are attached directly to the wall in the opening or above it, depending on the mechanism used.

When installing the door frame, special mounting spacers are used

To make the passage look neat, it is necessary to level its surface in advance. Usually, plaster is used for this or combined with drywall sheets... Instead of a box, you can install decorative panels... They look almost the same, and the installation method is practically the same. Another option is to mount the lamellas on a rack frame.

Which finishing method to choose is up to you. If you decide to follow the traditional approach and install a swing door with a frame, follow the technology carefully to avoid significant flaws.

The final stage renovation works in residential or commercial premises - installation of interior doors. High-quality assembly and installation of the box in the appropriate opening is the key to reliable locking of the canvas, correct work main and auxiliary mechanisms.

The door frame is mounted in the wall opening, therefore it is a key part of the finished structure, to which the door leaf is attached to the hinges. We will figure out how to assemble a door frame with our own hands without the involvement of third-party specialists, following a simple step-by-step instruction.

Choice of box sizes

Frames for interior doors are made of reliable and practical materials- MDF, chipboard and wooden beams. The design of the box consists of several functional elements, therefore, for its installation, it is necessary to know the dimensions of all components.

Door frame dimensions interior door are determined by the thickness of the walls and the dimensions of the door leaf:

For walls made of bricks with a thickness of 7.5 cm - a box with a thickness of 10.9 cm;
For walls made of wooden paving stones up to 10 cm thick - a box 12 cm thick.

The thickness of the door frame from foreign manufacturers may differ from the indicated dimensions, amounting to:

8 cm;
10 cm;
12.5 cm;
14.5 cm;
18.5 cm;
20.5 cm.

The correct ratio of the parameters of the thickness of the box and the wall opening excludes the occurrence of violations in the future. With a wide wall and a narrow box, finished structure needs to be expanded with wooden planks or boards installed in special grooves.

As standard, the frame for the opening is equipped with a special cutout, the depth of which is equal to ¼ the thickness of the door leaf.

Modern models of interior doors can have different dimensions, but standard size- 80 cm. The width of the door frame is presented in two ranges:

Height - 2 meters, width - from 60 to 80 cm;
Height - 1.9 meters, width - from 55 to 90 cm.

Finished products are regular and profile, and the width standard elements can be from 1.5 to 4 cm.

Tools and materials for work

The installation of the door frame is carried out using the basic tools and the necessary materials.

To work you will need:

Wooden beams and wedges.
Electric cutter.
A hacksaw equipped with a miter box.
Screwdriver.
Drill.
Self-tapping screws, nails with small heads.
Construction level.
Polyurethane foam.
Construction pencil.
A knife with a thin, sharp blade.

For installation works the room must be dry and well ventilated.

The box is a frame-type construction, consisting of vertical guides - a hinge and a false jamb. The hinge beam takes on the load of the installed door.

Preliminary assembly work

Do-it-yourself installation of interior doors is performed after finishing work on leveling wall surfaces, installing floor cladding and other finishing work.

Finished slopes should be vertically checked at several locations. If a difference of up to 5 cm is detected, the slopes are leveled. The horizontal jumpers are checked in the same way. A technological gap of 15 mm should be observed between the floor surface and the door.

Competent assembly of the door frame determines phased implementation works:

Using a cutter, small indentations are made for hinge joints in the door leaf. The distance from the edge of the fabric to the edge of the loops (top and bottom) must be at least 18 cm.
Slopes are cut at an angle of 45 degrees. The surfaces are carefully cleaned and trimmed, applied to the canvas and marks are made where the hinges will be placed on the jamb. Using a cutter, recesses are made for the door hinges.
The finished hinges are inserted into the existing grooves in the canvas, with the help of a drill holes are made for self-tapping connections. In this case, it is recommended to choose a drill, the diameter of which is equal to the diameter of the screws. At the end, the hinges are fixed to the door leaf.

Installing the handle and lock

The next stage of work is fixing the handle and lock on the door, which is performed after installing the hinges.

The canvas is turned over in the horizontal direction and a recess is drilled at a distance of 85 to 118 cm on the side opposite to the hinges required diameter for installing a lock with a latch mechanism.
The lock is inserted into the recess, the edging is made with a pencil. Using a cutter, another recess is made for attaching the front plate with a latch.
A latch is inserted into the canvas, while its body should be located at the level of the door end.
Further, on the door with a pencil, marks are made for the recesses for the handles, which are drilled with a drill.
The lock latch is mounted in the recess from the end part and fixed with self-tapping screws.

Finally, self-tapping handles and decorative trims are installed using a simple hex wrench.

Complete assembly and installation of the box in the wall opening

At the final stage, complete assembly door frame and its installation in the corresponding wall opening.

In the transverse box, the ends are trimmed at a 45 degree angle with a hacksaw. This will ensure an even and reliable docking of all elements. In this case, the width of the opening should exceed the dimensions of the door leaf by 6 mm.
The drill makes holes in the corner-type cuts for the correct connection of the box. Many door models, which are equipped with platbands and slopes, are equipped with special cuts and fasteners. In this case, there is no need to drill additional holes.
Next, the slopes are carefully shortened in accordance with the dimensions finished door, observing the technological gaps between the floor and bottom doors 15 mm.
All elements of the box are folded into a structure in the shape of the letter P on flat surface and are securely connected with self-tapping screws.
In the grooves that are intended for mounting the hinge, a through hole is made for fixing assembled box to the wall surface. The box is fixed at the top of the opening with a long self-tapping screw.
The vertical position of the rack to which they are fixed door hinges, checked by the building level. Correction is performed using wedges driven into the groove between the post and the slope.
A similar procedure is carried out with the second rack.
The horizontal arrangement of the lintel should be parallel to the floor surface. Correction is performed with wedges.
After a complete check of the position of the box, the structure is securely fixed from below on self-tapping screws.
Further, it is recommended to hang the door in order to check the correctness of the work.

Step-by-step instructions for assembling and installing the box suggest one more important stage- hanging the canvas.

Hanging the canvas is carried out using self-tapping screws, while the hinges reliably hide the fixing elements. When properly hinged, there should be no random opening / closing of the door.

After securely fixing the box and installing the blade, the wooden wedges are removed from the technological gaps, and the existing slots are filled polyurethane foam after closing all the installed fittings with masking tape.

Even a novice craftsman, with the necessary tools, can perform his first door installation, be it an apartment, house or bathhouse. The main thing is to observe all stages of work and carefully check the correctness of fixing all structural elements.

Doors, despite their external simplicity, are very demanding in installation. The slightest mistake can lead to disastrous consequences. Not properly taken dimensions, the cuts made cannot be corrected, and you will have to do it all over again using different materials. The gaps formed due to the erroneous sawing cannot be eliminated with the help of a sealant.

Even if this masks external defects, the structure will not be strong due to a loose fit to the surface. As a result, the load on the bars is significantly increased, and the service life of the door is reduced. In order to prevent such a situation, it is necessary to assemble the door frame with your own hands, strictly following the step-by-step instructions. It is important not only correctly, but also very carefully and accurately to carry out all the installation work.

The base frame must match the dimensions of the door (width and height) in order to provide full coverage and support of the structure. An important nuance relative to the canvas is the purpose of the room for which it is intended. Because ventilation requirements will depend on this. In steam rooms and saunas, doors must provide reliable thermal insulation, so the opening is sealed as tightly as possible.

The bathroom, on the contrary, needs to be well ventilated so that excess moisture does not accumulate and mold does not appear. Therefore, the gap between the box and the door should be slightly wider. And also good ventilation is required for rooms in which gas equipment is installed.

To provide reliable protection from heat leakage, a rectangular frame is constructed from four bars, which will serve as a frame for the door. The vertical posts will become the hinge and false element, and the transverse ones will become the upper support and threshold.

For free movement of the curtain, the gap between the door and the uprights should be about 3 mm. In cases where an air flow into the room is needed, the box is assembled from three bars, and a gap of about 10-15 mm is made at the place of the threshold. A standard distance of 3 mm is left along the uprights and lintels.

The assembled box is slightly higher than the complete threshold. The difference is about 20 mm. It is important to take this nuance into account so that you do not have to shorten the door. Because the canvas can only be adjusted if it is made of wood.

The gap between the door frame and the opening must be at least 10 mm on each side, so that the structure can be easily installed and fixed.

Required tools

A do-it-yourself door frame can be installed with the help of various tools, some of them are owned by many owners, but what is missing will have to be rented or purchased.

Miter box. A device that allows you to cut a bar under different angles.
Pencil, tape measure, construction tape.
Acrylic paint for wood.
Polyurethane foam for sealing the box.
Chisel, for making cuts for hinges.
Perforator, drill, screwdriver.
Claw, crowbar, hammer. For dismantling works.
Miter saw, hacksaw and stationery knife.
Building level.

Dismantling

If the doors are not installed in a new room, but the structure is replaced. Then you can do the installation of the door frame with your own hands only after the old one has been removed. The door frame is dismantled in the following order:

The platbands are removed, and the elements of the box are disassembled.
Fasteners and anchor bolts are unscrewed.
The strength of the opening is checked and, if necessary, it is strengthened.

It is worth very carefully disassembling the door frame in order not to damage anything and thereby increase the volume of installation work in the future. If it is necessary to replace the door frame, it is recommended to dismantle it in advance so that there is time to prepare the opening. It is almost impossible to remove a door frame without damaging it. Therefore, after removing the old components, you will need to install new ones.

How to assemble a door frame?

The assembly diagram will help to make a door frame from blanks correctly.

The box must be enlarged with the help of an extension, if the width of the wall is more than 70 mm, and the platbands are placed on both sides.

If the door frame is assembled from MDF, all fastening work must be carried out with preliminary reaming so that cracks and chips do not form on the product.

How to saw down a door frame at 45 degrees?

Elements with a rounded section are cut at an angle of 45 °. In order to make the correct cut, use a miter box or miter saw with a rotating table.

Do-it-yourself doorframes can be assembled without the use of special tools. In such cases, you can saw off the desired angle without a miter box, using a ruler and a protractor for marking.

When installing, the structure is fixed with self-tapping screws, which are screwed in at an angle.

Assembling the box at a 90 degree angle

With this option, the assembly of the door frame is quick and easy.

It is necessary to saw off the required size of the racks and the horizontal crossbar at a right angle.
Choose an extra part of the vestibule.

Place the elements of the box on the floor, align and fix at the ends with self-tapping screws (2 in each).

In order for all sides to maintain parallelism, you can attach the door to the door frame and check how it will stand in the opening. The connection of the door frame at 90 degrees is considered by specialists to be a quick installation technology.

Assembling the box with a threshold

There is no significant difference between installing door frames with a threshold and without it. Thresholds in Lately have lost their relevance. But, despite this, such a system has a lot of fans. This is explained by the fact that it is stronger and more reliable than a structure without a lower transverse bar. Such systems can withstand significant loads and are suitable for installing solid wood doors. Thresholds are considered a prerequisite for bathrooms. Regardless of what type of construction is chosen, each person will be able to assemble the frame of the interior door.

Prepare vertical and horizontal strips in advance.
Cut at 45 or 90 degrees.
The prepared elements are placed on a flat surface.
In turn, fasten the racks and crossbars with self-tapping screws.

How to install the door frame correctly?

The installation of the door frame is carried out after a preliminary check of its compliance with the dimensions of the opening in the wall.

In the event that everything fits, the door frame is installed in the opening.
Using the hydro level, the verticality of the racks and the horizontalness of the crossbars are checked.

Wedges (about 15 pcs.) Are installed around the entire perimeter of the structure. Spacer for door frames increases strength.

Make markings for the attachment points. Holes are drilled along it on the bars and walls. Many experts attach the door frame to the wall in the places where the hinges and the lock striker are located. This allows you not to violate the integrity and appearance products.

The fastening of the door frame is carried out anchor bolts which are inserted into the holes and tightened with a screwdriver or wrench(depends on the type of fastener). The structure should be fastened very carefully.

Fasten the hinges and hang the canvas. At correct installation opening and closing the door will be easy.

The gap between the block and the wall is filled with polyurethane foam.

Reply metal bar the lock is installed on different stages: during assembly or when the structure is already fixed. The second method will be more correct and accurate.

Cover the doors and mark with a pencil the location of the tongue or magnet.
With a chisel or a feather drill, make required hole... Too deep is not necessary, the main thing is that the tongue fits and holds the door.
A sample is made according to the size of the striker and installed, securing it with self-tapping screws. It is not necessary to mount the element very deeply, this will ruin the appearance.

The gaps are putty with sealant.

What else is important to know?

Not every person will succeed the first time with a high-quality installation of the door frame. But don't despair. Because many flaws can be fixed.

If there is an ugly seam, you can close the joint between the laminate and the door frame with a plinth or a special flexible sill.
If the box does not fit into the opening, then the racks and cross bars can be trimmed a little.
Platbands allow you to beautifully seal the gap between the door frame and the wall. If their width is not enough, you will have to plaster and decorate the gap.
To install an interior door frame in concrete wall or made of brick, it is impossible to do without a punch. If the MDF door frame is installed on the slats, using a drill, holes are made and only then they work with a punch.
Fasten the door frame to wooden wall much easier than other materials. In this case, a hammer drill is not useful for drilling holes. You just need to screw the door frame to the wall with the help of anchors. The main thing to consider is that over time wooden buildings can shrink a lot.
To facilitate the installation process, special door frame installation systems have been created. Thanks to them, the structure can be placed in walls made of any material, without using wedges and spacers. This kit includes fasteners concealed installation, detailed step-by-step instructions and diagrams. Using the system, even a beginner can insert a door frame.

Installing a door (interior or entrance) requires accuracy and attention. The main condition for long-term and comfortable operation is the verticality and horizontalness of the door frame. It is to this aspect that you devote close attention... Then the doors will open and close normally, they will not be distorted, the hinges will not creak.

The interior doors are mounted after they are finished. Finishing work on the walls and ceiling. The sub-floor must also be ready, the flooring has been laid, but the skirting boards have not yet been installed.

There are three types of door configurations:

Choose the option that seems more attractive to you. Naturally, their cost is different, but labor and time costs are also very different.

Door frame dimensions

About door sizes building standards v different countries differ. For example, in our country, the width is considered standard swing door 600 mm, 700 mm, 800 mm, 900 mm. Similar regulations in Spain or Italy. But in France, 690 mm, 790 mm and 890 mm are considered the norm.

What to choose? More often they prefer to adhere to domestic norms: there is more choice. Installing doors that do not meet building codes leads to the fact that to replace them you will need to look for the same or redo the doorway. There are no other features.

In general, the width of the door leaf and doorway is regulated by GOST. He defines them depending on the room:

But the realities are such that we are adjusting to what we got from the builders. Therefore, in order to determine the size of the door and frame, it is necessary to measure the existing opening. Based on the results (the smallest value), select the dimensions of the block that will be slightly smaller. Necessarily less, since clearance is required for the installation of fasteners and spacers.

When taking measurements of the doorway, inspect the walls. Repair and reinforce if necessary: the box will hold up better. The condition of the walls is especially critical when installing heavy doors. If possible, you can attach a block of wood at least 50 mm thick to the wall and plaster it. It will then be convenient to attach the box to it.

There is also such a parameter as the depth of the box. The standard is 70-80 cm. But in many private houses, the wall thickness is many times wider. Then the doors are installed flush with one of the walls so that the opening and slopes do not interfere with opening them. The remaining width of the opening can either be plastered and finished in the same way as the walls, or you can install an additional strip, which is selected to match the door leaf and door trims.

Read how to set the additional bar here. It is written here about the installation of platbands on the door.

How to assemble and install a door frame

If you bought doors with a frame, you will need to fasten the vertical strips - racks (jambs) - with the horizontal - lintel. This is usually done on the floor. Having spread paper or cardboard, the planks are laid out on the floor. Connect, checking the exactness of the match. If necessary, eliminate the disadvantages: process sandpaper, achieving the absence of gaps.

If you bought doors with a box, you shouldn't worry about the dimensions, but you still need to check. Just in case, so that you don't have to redo it later. Therefore, having folded the details of the door frame on the floor, put the doors between them. If everything is correct, then a gap of about 3-4 mm should remain around the perimeter of the door leaf. Only under this condition will the doors open and close normally.

There is little to say about height adjustments. Usually, the side racks of the box are made 12-15 cm longer than the door. This is in case the doors are mounted according to the rules: the racks will rest on the floor joists. But since this method of installation is rare today, the racks are shortened to the desired length.

Assembling the box and adjusting it in height

The next stage is the assembly of the door frame. It is better to do this with self-tapping screws. If the corners of the planks are cut at 45 o, obliquely drill holes for self-tapping screws on the side plank, as shown in the photo. Then we apply it to a horizontal bar and twist it with self-tapping screws.

When assembling the door frame, we drill holes for self-tapping screws - this way wood or MDF will not crack

If the corners of the box are cut at 90 o, it is a little easier to work, but it is still advisable to drill holes. This is definitely necessary if the box is made of MDF: this will guarantee that the material will not collapse.

The upper bar is placed against the side bar, the edges are aligned. Two holes are made: the upper bar through and through and into the end of the side bar. It will be clearer if you look at the photo.

By connecting the strips in this way, you get a finished box. The lower bar is practically not used today, because there is nothing below. Check again, in the assembled state the frame is 3-4 mm larger than the door leaf (both wider and longer). You can check.

Often the height of the posts is greater than necessary. Take a tape measure, measure the height of the doorway, subtract 1-2 cm, which will be filled with foam. This will be the height of the box. Measure on each side of the opening separately: After measuring again, put this value on the racks of the assembled box, draw a cutting line. Cut off the excess. Half of the installation of the door frame has already been done by you, and with your own hands.

Embed the hinges

One part of the hinge with a pin is fixed on the frame of the door frame (1), the second - at the end of the door leaf (2)

At what height should the hinges be installed? The distance from the edge of the door leaf must be at least 19 cm. For light doors, two hinges are sufficient - at the top and at the bottom. Three are installed on heavy ones: one more in the middle.

The hinges consist of two detachable parts, one of which has a pin. We put them so that the pin looks up. It is important.

It is more convenient to embed hinges and locks directly on the floor. Therefore, we take the fittings, attach them, mark them out and make recesses. First, we cut in and fix it on the rack. Then putting the doors down, we mark the place for the hinge at the end of the door leaf.

It is convenient to work with a milling cutter, if it is not there, we use a chisel. You only need to remove a few millimeters of material, so it doesn't take long. When folded, the hinges leave a gap between door leaf and a rack of 4 mm. Taking this into account and the thickness of your loop, we calculate the depth of the seat.

Having installed the hinges on the rack, we apply the canvas and at its end we mark the place where the hinges will be attached. Cut to the same depth as on the rack.

Installing the box

Place the racks and lintel assembled with the letter "P" in the doorway. With the help of a level and / or plumb lines, set in the horizontal and vertical plane. Fix the position with wedges and spacers, constantly checking for correct installation. Pay attention to the fact that the struts are parallel, not topple either sideways or forward. The comfort of using the doors depends on how evenly you expose everything.

After checking everything again, with long screws or dowels - depending on the wall material - fix the box canvas in doorway... One fastening on the door frame from the other is located at a distance of 25-30 cm.It turns out that on upright racks fit 7-8 self-tapping screws, 2-3 pcs on the lintel.

A hole is drilled in the box itself with a 4 mm drill, no more: the caps of the screws are 5-6 mm, and if you do more, they will not hold. This is where the timber built into the opening comes in handy (if there is one, of course). Self-tapping screws easily screw into wood and hold the box securely.

If the opening is brick, made of building blocks or shell rock, everything is more complicated: installation of dowels is required. Moreover, they should fall into the bricks, and not into the seam. And the diameter of the dowels is more than 4 mm, and they still need to be installed somehow.

Proceed as follows: drill with a thin drill 4 mm, trying to leave a mark on the wall. Having drilled everything, they dismantle the box, check where they got: into a brick or a seam. In order not to get into the seam, look at the area of open masonry, or apply marks in advance on the box (only those that can then be erased). If everything is fine, make holes for the dowels, if they hit the seam, make adjustments. Dowels are inserted into the holes drilled in the wall.

To make it easier to put the box in the same place later, you can mark its edge on the wall with a pencil, marker, etc.

Expose the box again, making sure the holes in the box and the dowels match. Wedge and check once again how correct it is. Insert the crepe into the dowels, periodically checking it relative to the vertical and horizontal plane. Do not tighten too much - you can either damage the wood, or bend the stand.

Now install the door leaf. It is simply hung on the hinge pins. After checking the door is working properly, close it. Now the gap between the box and the wall must be filled with polyurethane foam.

Foaming

First, we fix the doors by placing some dense material, cardboard, for example, between the canvas and the jamb. At closed door we install wedges and spacers that will not allow the box to bend.

Then we take a can of polyurethane foam and fill the gaps between the box and the wall by about one third. No more foam needed. And this amount is more than enough. When it dries, it increases very much in volume. If there is too much of it, then it can bend the box strips. We'll have to dismantle everything and start over. Therefore, 1/3 of the volume of the slots is sufficient. After laying the foam, leave everything for about a day.

Then you can remove the spacers, cut sharp knife surplus foam and proceed with the installation of the add-on (if the doorway is wider than the frame) or the installation of platbands.

Outcomes

Do-it-yourself door frame installation is a responsible job. It requires attention and scrupulousness. But you don't need any superpowers. If you can handle even a little with a hammer, drill, chisel and self-tapping screws, you can definitely do it.

The door frame is fixed in the entrance opening of the wall and is part of door structure, on which a sash is hung with the help of hinges, which serves as an obstacle to entering or exiting the room. The box is made of MDF, chipboard or timber thickness 75-85mm. With a wall thickness of more than 85 mm, additional strips are used, which are installed in special grooves of the beams. The door frame has a 1/4 cutout equal to the thickness of the door leaf.

For the installation of the hinges in the box, material samples are made for an amount equal to the thickness of the hinge sash. This is necessary for a snug fit of the door leaf to the frame jambs. Butterfly door hinges are installed without a tie-in.

The door frame is a frame structure. Its vertical components are called jambs, one of which is looped, the other is feigned. The hinge beam carries the main load of the door leaf. The horizontal top box lintel is called “headroom”, and the bottom one is called “threshold”. The threshold in the box is optional. It is installed when it is necessary to eliminate drafts, blocking the gap under the door leaf. Threshold doors are often installed to contain spilled water from entering adjacent rooms. The gap between the floor and the threshold hides the thickness flooring...
