What type of timber to choose for building a house? The section of the bar. Standard dimensions of a wooden bar What is the standard length of a bar

Before completing the construction of a wooden house, you need to understand how the type of building material should be used in order to achieve an excellent result.

Let us dwell in more detail on the most common types of timber, as well as their sizes, which are so important to know when building an object.

Dimensions for all types

Today, in the field of construction, such types of bursas as profiled, ordinary and glued have become especially popular. Each of them has its own characteristics, weight and dimensions. But what is better to use, the information on the link will help to understand.

The picture shows the standard dimensions of the timber:

Normal

This material belongs to the most demanded today. It can be classified into planed and non-planed according to the processing method. The second option is used in places where surface treatment does not play a special role.

Taking into account the dimensions of the section, such a material is called a bar with a thickness of 100 mm, and a bar with dimensions over 100 mm. Very often you can find a cross section of up to 250 mm; they are used in the case when it is required to obtain bulky products for specific purposes.

Glued

The process of making such a material involves gluing with alternating direction of the hair at the next board, as a result of which the finished product acquires high strength values. Another advantage of such lumber is the absence of shrinkage. This quality is achieved during production, since the finished wood is dried with high quality. When choosing the size of laminated veneer lumber for building a house, you do not have to worry that shrinkage will occur, all dimensions will remain unchanged. You may also be interested in information about what is

In the photo - glued laminated timber

There is a myth that glued laminated timber is inferior in quality to solid timber. But these doubts can be immediately dispelled, because the glued material is obtained by gluing several boards, as a result of which dry raw materials and non-toxic adhesives are used.

As a result, it is possible to achieve excellent performance without losing the ability to "breathe" wood materials. Various manufacturers of laminated veneer lumber offer the following cross-sectional dimensions: 150 mm, 210 mm, 270 mm. The choice of the required thickness depends only on your decision, then you should adhere to this rule: an unjustified increase in the thickness of lumber will negatively affect the cost of construction, because the price of such a bar is considerable.

It is necessary to make the choice of laminated veneer lumber in such a way as to maintain a balance of properties depending on the thickness. These properties include thermal and ecstatic properties. And here is what a dry profiled bar of a chamber drying looks like, you can see

The dimensions of laminated veneer lumber, taking into account the purpose, can reach the following values:

wall - 140 × 160, 170 × 160, 140 × 200, 170 × 200, 140 × 240, 170 × 240, 140 × 280, 170 × 280 mm;
- from 85 to 1120 mm in height, from 95 to 260 mm in width;
window - 82x86, 82x115 mm.

Profiled

The production of the presented sawn timber is carried out from solid wood or prefabricated sections with different profile geometries:

Thanks to this configuration, the profiled timber becomes very interesting in the construction of wooden houses. A log house made from this bar does not require finishing measures, because in addition to an attractive appearance, such material will be a true protection from cold and moisture.

But what are the advantages of a profiled bar and how to use it, is indicated in this

The dimensions of the profiled bar are presented in the following range:

100x100;
100x150;
150x150;
150x200;
200x200 mm.

Depending on the thickness, the profiled timber is used as follows:

100 mm - simple structures made of wood: gazebos, baths, verandas. It is possible to use such material for the construction of a summer house, the operation of which takes place in the warm season. The profile with this thickness is 2 grooves, 2 spikes. In one m3 lumber with a section of 100x150-11 pcs., 100x200-8 pcs.
150 mm- construction of houses in areas with a mild climate. This lumber is characterized by a profile such as a comb. They are able to protect the structure from low temperatures. One m3 of timber 150x150 - 7.4 pcs., 150x200 - 5.5 pcs.
200 mm- the classic thickness of the timber, which is actively used in the construction of a dwelling. The cost of such lumber is more expensive, however, its thermal characteristics contribute to the installation of a reliable log house without additional thermal insulation. In this case, builders use material with a section of 200x150, 200x200 mm. In one m3 200x150 - 5.5 pcs., 200x200 - 4 pcs.

But how many 100x100 timber in a cube, you can see

To obtain maximum thermal insulation performance, it is necessary to use a seal. An example of such a material is jute felt. It is laid between the grooves in order to prevent the formation of new cracks. The advantage of such a seal is the ability to take the form that is required. When choosing high-quality lumber, shrinkage will never occur; for this reason, felt strips can be used in order to eliminate cracks.

As for the length, for a profiled bar it is adopted by the standard 6 m. But similarly with the profile section, this value can be set taking into account the wishes of the customer. To reduce the cost of purchasing materials, it is better to use.

Dimensions for building a house

The roof structure provides for two main components - the rafter system and the Mauerlat. If it is necessary to carry out the installation of rafters, then it is advisable to use a beam obtained from hardwood, the cross section of which is 10x150 mm.

When installing the Mauerlat, it is necessary to use wooden beams, the cross-sections of which are 10x10 or 15x15 cm.The thickness of this element should not be less than 10 cm, and from the edge of the outer edge of the wall it should be 6 cm or more.

When erecting a wall from a bar, its thickness is determined taking into account the temperature indicators in the cold season. If the temperature is -40 degrees, then you need to use a beam with a section of 18x18 cm, up to -30 degrees - 15x15 cm.When building internal walls, it is advisable to use materials with dimensions of 10x18 cm and 10x15 cm.

The video shows the size of the bar for the Mauerlat:

But what kind of insulation for wooden walls is outside, you can see

GOST 8486-86

In the field of construction, a beam is used, the dimensions of which will be:

200 x 200;
200 x 150;
150 x 150;
100 x 100.

Very often, when erecting various structures, blanks with a section of 100x200, 100x150 are used. GOST 8486-86 determines that coniferous woods are used to obtain such products, including: cedar, fir, pine, larch, spruce.

It is also useful to know which ones.

The timber plays a huge role in the field of construction today. The reason for this demand is due to the fact that this material is reliable, beautiful and environmentally friendly. But when choosing a bar, it is important to consider such a parameter as size. If you choose the wrong section, you can overpay for unnecessary material, and the cost of the timber is not so small. It will also be useful to read about.

Many new synthetic materials with excellent characteristics that have flooded the market are again pushed aside by the traditionally reliable, warm, natural material - timber used for construction.

Initially, a beam was considered to be a log that was comprehensively planed until a section was obtained that was the same along its entire length. Now the concept of a bar has changed - it can be made by gluing layers or mixing sawdust into a homogeneous mixture with adhesives.

When erecting buildings, timber is used in a variety of ways: it is possible to make structures of beams, trusses, girders, a solid wooden beam will come in handy when forming walls.

What buildings are not made of wooden beams: whole palaces, and houses, and baths, and gazebos, as well as many other colorful buildings for other purposes.

About wood species for cutting timber, GOSTs and sizes

Conifers give a more durable, dense timber; they are less susceptible to damage by pests, due to which products from fir, cedar, larch, spruce, pine are more durable.

Resin of coniferous species impregnates the layers, making them less susceptible to fungi and mold, which makes it possible to install parts from them in places of possible moisture ingress in any form - in the lower rows, in the frames of windows, doors, etc.

Depending on the part of the trunk from which the timber is cut, the quality of the finished product is obtained with various kinds of disadvantages.

These include slanting, cracks, the presence of a core, the degree of damage by pests, fungi, as well as other deviations from the standards according to which a wooden bar is divided into grades - from I to IV.

Hardwood, from which timber is prepared, are limited mainly to two - birch and aspen. A timber from these rocks is placed in the walls only in the middle, driest part.

For guidance on working with wood, use special regulatory documents:

GOST 8486-86 "Softwood lumber";
GOST 2695-83 "Sawn hardwood";
GOST 23431-79 “Wood. Structure and physical and mechanical properties. Terms and Definitions";
GOST 18288-87 “Sawmill production. Terms and Definitions";
GOST 24454-80 “Softwood lumber. Dimensions ".

The diameter of a wooden beam, that is, the width, is unified within such limits as 100, 125, 150, 175, 200, 250 mm; the lengths of a solid bar can be in the range from 2 to 9 m, the standard of 6 m prevails. When custom-made, it is possible to supply products of individual parameters.

The width of the workpiece, which forms a section of 100 x 100 or more, is called a bar, a smaller section - a bar. The most demanded sections of the timber:

100 x 100 mm;
150 x 150 mm;
200 x 200 mm;
200 x 150 mm.

Other options are also possible.

The weight of the timber will depend on its dimensions (section and length) and the type of wood from which it is made. Without tying the type of wood, you can give the approximate weight of 1 piece. Knowing how many pieces are in 1 cubic meter, you can already approximately find out the weight.

200x200x3000mm. - weighs 103 kg. One cubic meter contains 8.3 pieces.
200x200x4000 - weight 138 kg. 1 m3 - 6.25 pieces
200x200x6000 - weight 210 kg. In 1m3 - 4.1 piece.
200x150x6000mm - weight 156kg. In 1 m3 - 5.5 pieces.
200x100x6000mm - weight 104kg In 1 m3 - 8.3 pieces.
150x150x6000mm - weight 116 kg. in 1 m3 - 7.4 pieces.
150x100x6000mm - weight 78 kg, in 1 m3 - 11.1 pieces.
100x100x6000mm - weight 52 kg in 1 m3 - 16.6 pieces.

Varieties of timber

There are types of timber associated with the manufacturing method:

solid (rectangular or rounded);
glued;
batch;
thermobeam;
hollow.

Any type of section can be either square or rectangular. A bar with protrusions and slots at the top and bottom, which gives a very high-quality grip during laying, with minimized moisture during operation, is called profiled.

Such a characteristic of wood as moisture is of great importance: when drying in the wrong mode, there can be cracks, bends in length (warping) and other troubles, therefore, the logs are dried before processing.

A maximum moisture content of 20% for raw materials is considered normal for 1–3 grades that are suitable for use in construction. Structures and parts are not produced from wood of the 4th grade.

Glued laminated timber is most in demand as the most economical and at the same time durable. It is obtained by connecting the layers with a special glue until a given section is formed; it is less prone to deformation.

Wooden houses from a bar and not only

A series of residential houses assembled from wood have been developed; by choosing the serial design you like, you bring the housewarming date closer, because the designers have already drawn up specifications for the necessary structures and parts, depending on the area of the dwelling.

Wooden houses look so modern and attractive and at the same time so strikingly different that the owner of another wooden building may not be afraid to become the owner of a twin house.

They are very interesting externally and captivate with the thermotechnical properties of houses made of rounded logs, reminiscent of a log hut cut down from logs. When using cylindering, wall insulation is not required, and the external finish is limited to coating with varnish. By the way, from the color of the stain, any spectrum of shades can come out - from sunny yellow to dark brown, the "antique" style can be beaten by the device of a carved porch, balcony.

Profiled timber gives a completely different picture, the facades of such houses can be made in other styles, inside flat surfaces it is easier to cover with a heat-insulating layer. Flat walls provide more options for interior finishes.

Frame-type houses are in great demand, in which the main structures that receive loads are made of wood; outside, such houses are most often trimmed with clapboard sheathing. Frame houses can be made with any configuration of facades, with greater variability for choosing a style, glazing area, number of storeys.

Build your dream home

If the choice of material for building a house fell on a wooden beam, draw the house of your dreams in your imagination as accurately as possible, specify the choice of number of storeys, the shape of the roof.

Knowing exactly what you want, reconsider the projects of wooden or frame houses: suddenly someone has already depicted the structure you have imagined. If you have not chosen anything similar, order an individual project for a house, cottage, cottage or other structure.

If you decide to build a house from a bar or are planning such a construction in the future, then first of all you need to calculate the amount of material that will need to be purchased. In order for your calculations to be correct, you need to know standard sizes of timber and edged boards, since these materials are the most commonly used lumber in the construction of wooden houses and houses from a bar.

To calculate the number of cubes of profiled timber, to build a house, you can use the timber calculator.

As a rule, construction timber has the following dimensions:

150 * 150 mm;
100 * 150 mm;
100 * 100 mm;
A small bar has dimensions of 40 * 40 millimeters and 50 * 50 millimeters.

The standard length of the bar is 6 meters, the longer bar is made to order. When ordering such a bar, it is necessary to take into account the possible difficulties during its transportation, since not all types of transport are suitable for transporting material of this length. The standard sizes of edged boards are 100 and 150 mm in width and 50, 40 and 25 mm in thickness. As with the timber, the standard for the length of the board is 6 meters.

Sizes of edged boards and beams in accordance with GOST.

The dimensions of the timber are regulated by GOST and the products of any sawmill are focused on standardized dimensions. Sawmills produce completely different products, such as edged, unedged boards, bars and beams, and so on.

By quality, deciduous wood species are divided into 3 grades, conifers - into 5. Sawn timber of the highest grade is called selective (marked with a horizontal stripe or the letter "O"), other grades are marked with numbers 1-4 (marked with the corresponding number of dots, vertical stripes or just a number) ...

Table for all standard sections of the board GOST 8486.

Board cross-sections, length in mm.	Mathematical action	number of pieces in 1 m 3

Varieties and symbols of wood.

First grade wood It is used to create elements of building structures, windows, doors, stairs, finishing the floor and walls. The moisture content of the variety should not exceed 22%.

Second grade of wood are used for flooring, load-bearing building structures (category II) formwork, battens and planed parts. The moisture content of the variety should not exceed 22%.

Third grade of wood used for the production of load-bearing structures (category III). The moisture content of the variety should not exceed 22%.

Fourth grade of wood suitable for the manufacture of containers, small workpieces. Permissible moisture content of the 4th grade is not standardized.

The designation of the timber indicates the material (board, bar, timber), then the number that determines the variety, species of wood (coniferous or other types of wood - pine, spruce, larch, cedar, fir) is indicated. Then indicate the size of the cross-section in millimeters and the designation of a specific standard.

How it looks: Board - 2 - spruce - 40 x 150 - GOST 8486-86

Some manufacturers also indicate the length and volume of the product: Board - 2 - larch - 40 x 150 x 6000 - GOST 8486-86 Number in a cube: 27 pieces.

Measurement of lumber.

To measure the length of lumber and blanks, you need to fix at the smallest distance between the ends, and the width is measured anywhere, but retreating 150 millimeters.

The thickness of lumber is measured in the same way at an arbitrary point with an indent of 150 millimeters. The width of unedged lumber is determined in the middle of the length (excluding bark).

The volume of lumber is determined in cubic meters based on the dimensions determined by GOST 5306 - 83.

The dimensions of the cross-section (a x b) and length (L) of edged boards are determined by GOST 8486-86

1 is a length of 6.5 meters, with a graduation of 0.25 m.
a is the width of the edged board: 75, 100, 125, 150, 175, 200, 225, 250, 275 mm.
b is the thickness of the edged board: 16, 19, 22, 25, 32, 40, 44, 50, 60, 75 mm.

How many pieces of edged board are in 1 cubic meter of lumber.

Board dimensions	1st board volume	Planks in one cube (pieces)

The weight of 1 m 3 is calculated by the formula: M = V * P

M - weight.
V - volume
P is the density of wood, which depends on the type of wood, its moisture content, the place of growth, the specific part of the trunk from which the board is made.

Density table of various woods.

Calculation example: let's say you need to know the weight of 1m 3 of a pine board: M = 1 cubic meter. m. * 520 kg / cubic meter m. = 520 kg with a moisture content of 12% (the physical and mechanical properties of wood are calculated with this indicator)

Absolutely dry wood will have a lower density (the equilibrium moisture content of wood for indoor use is 6-8%), and higher for natural moisture. Natural humidity is not standardized and can vary from 30% - 80%.

Beams is a board whose dimensions correspond to the following inequality: a / b< 2. Длина бруса будет равна длине обрезной доски. Нестандартные размеры всегда могут быть выполнены под заказ.

Size a (width) of the timber: 50, 60, 75, 100, 130, 150, 180, 200, 20, 250 millimeters.
b (thickness) 130, 150, 180, 200, 220, 250 mm.

The length of the bars is equal to the length of the edged board.

Wooden houses are the most environmentally friendly and favorable for human life. No wonder, wood is almost the first material that began to be used to build a dwelling. Modern technologies have given this material new possibilities and improved its properties. Using various processing methods, types of timber are made from wood for the construction of houses of various sizes and designs.

When choosing a timber for the construction of housing in a country house or a large residential building, you need to remember that the requirements for the material in each case will be different

Reasons to choose a bar for building a house

A bar made of wood allows you to exclude some of the properties of wood, which complicate the construction process, making it more laborious. The timber is made of a unified profile and length. Folding a house out of it will turn out quickly. If you carefully calculate the required volume, you can avoid unnecessary waste of material, which will significantly reduce the estimated cost of construction.

Glued laminated timber is not subject to shrinkage, does not crack under the influence of the surrounding climate. It does not lose its properties during long-term use. When laying a bar with flat edges, a flat wall is formed, it is easy to cover it with finishing material or insulation.

Types of timber for building houses and sizes, advantages and disadvantages

Let's figure out what kind of timber is for building a house. There are 4 types of material:

not profiled from the array;

non-profiled glued;

profiled from an array;

profiled glued.

Regular construction timber

This option represents a log blank with rounded side semicircular edges. They are given a square section, with a side size from 100 to 250 mm. The material is naturally dried before use.

Bars of different sizes are selected depending on the purpose of the future structure

Its use in construction cannot be called the best solution. Suitable for the construction of simple building structures. It has certain disadvantages, let's list them:

naturally dried wood is subject to shrinkage, warping and cracking during operation;

loose adhesion of the bars to each other leads to the need to insulate and seal the cracks between them after a while;

the material does not undergo finishing, therefore, surfaces need to be finished in order to get a beautiful and neat wall;

requires additional strengthening of load-bearing walls and corners of the house;

impregnation with special compounds is necessary to give the structure fire and bacterial resistance.

Of course, this is a fairly cheap and widely available material. If you agree to incur additional costs in order to refine it to the desired qualities, then this option will be quite acceptable.

Profiled timber

For him, use the same whole logs as for a regular planed one. Processing is carried out on woodworking equipment with precise settings. It allows you to get a perfectly smooth surface and ideal dimensions.

The profiled beam allows the material to adhere tightly to each other and during the operation of the house to prevent drafts between the cracks

The process differs in that first, the sawn logs are dried to 22% moisture content or less, and then further work with them is carried out. The connecting planes have a comb or tenon-groove. When the comb touches the adjacent bars, a tight joint is obtained between the crowns. The thorn-groove allows you to put insulation in it, which creates a tight connection of the crowns that does not allow air and moisture to pass through.

Of the shortcomings of such a material, the preservation of wood defects that may exist inside the log, and the obligatory time for shrinkage, are noted, since it is inherent in all types of wooden structures.

On our website you can familiarize yourself with the most popular projects of houses from a double beam from construction companies presented at the exhibition of houses "Low-rise Country".

Glued laminated timber

This version has a calibrated cross-section, the connecting surfaces are made in the form of a comb or a thorn. Sometimes it is given the shape of a rounded log - D-beam. Externally, the wall made of it looks like a natural log, which is now very popular.

A house made of laminated veneer lumber is ready for use much faster, but it is important that the lamellas are glued with high-quality glue

Such material is made of separate wooden plates, they are glued together with a special glue under pressure. Has a number of positive aspects, namely:

A well-finished surface has a finished look, does not require additional finishing. The presence of locks creates a dense wall without cracks.

The design of the timber eliminates warpage, it does not crack and is not subject to deformation during operation.

The constructed building does not shrink. This significantly shortens the construction period.

Disadvantages:

The high price of the material, in comparison with the usual timber.

The glue included in the timber makes it less environmentally friendly.

The microclimate in the house will be different from the conditions that occur in a real wooden structure. Ventilation must be done in glued timber houses

On our website you can find contacts of construction companies that offer the service of building houses from a double beam. You can communicate directly with representatives by visiting the Low-Rise Country exhibition of houses.

LVL bar

Its production technology is similar to the production of laminated veneer lumber. Only the material used for it differs. For manufacturing, take veneer from various trees, 3 mm thick. In adjacent veneer layers, the grain direction is the same.

Veneered timber is quite expensive in terms of cost, it is more often used for individual building units

It is a durable and flexible material, but very expensive. It is used to complete individual structures at home. In most cases, it is unprofitable to build an entire house out of it.

Which timber is better for building a house should be determined taking into account the requirements for it and the availability of funds from the developer. A well-dried and properly processed ordinary planed timber will serve no worse than an expensive glued material.

Types of timber connection

When erecting a log house, it is necessary to connect individual elements when crossing at an angle or when the length of the elements is insufficient. Several types of connections are used.

The most popular and convenient compounds are those with and without residue, in a cup or in a tooth.

Compound with the remainder

One-way connection. One side of the bar is sawn across the element, the width of the cut is equal to the width of the element to be attached. This is the simplest and most commonly used method.

The connection of the bars with the remainder is used more often than others, and the fastening of such a bar is more reliable

A double-sided lock requires cuts to be made at the top and bottom of the bar. Their depth is one fourth of the thickness of the element. The use of this technology creates a high quality joint, but will require the work of experienced carpenters.

The four-way connection is the most complex and the most reliable and accurate. The cuts are made from all sides of the bar. The building is assembled like a constructor - quickly and efficiently. In this case, all dimensions must be exactly observed, the cuts are made strictly at right angles.

Residue-free connection

This view has many variations. Here are the frequently used ones.

Butt joint. It is carried out using studded metal plates, they are fastened with nails or staples. For this purpose, connecting dowels are also used, which fix the joint well, preventing the bars from moving and turning.

In this case, it is imperative to use additional fasteners, otherwise the house may lead to the side

It is good to use a tenon joint. The spike can be in the shape of a triangle or a trapezoid. The root thorn is popular. A groove is cut out on one of the bars, a thorn of the appropriate size is cut in the other. With this connection, you can use insulation made of vegetable felt or jute fiber.

Choosing the thickness of the timber for building a house

The nomenclature of unified timber dimensions has the following values: 100, 150, 200, 250 mm. The main requirement in determining the thickness of the walls of the house is that it must give a certain strength to the structure, have sufficient heat capacity to create a favorable climate in the house.

To determine which timber is best for a house of 150 or 200 mm, you should know what kind of house you will build. For a one-story building, a thickness of 150 mm is sufficient. If the exterior decoration or wall insulation will still be done, then this is undoubtedly.

For two-story buildings, a stronger and more rigid structure is needed. In this case, a section of 200x200 mm will be justified.

To build a house for seasonal residence in the country or a bathhouse, if you do not insulate them, use a bar with a section of 150x150 mm.

For such a house, for temporary residence, a simple bar of medium thickness is enough

If you build a residential building for permanent residence of people, it will have to be heated. The walls of such a block house must be insulated, otherwise it will not meet modern energy saving requirements.

It is known that the thermal conductivity of wooden walls depends little on their thickness. The difference between the walls of 150 and 100 mm of timber will be 12% heat. From this we conclude that the walls to be insulated can be made thinner.

What to consider when choosing a bar: basic rules

Using the right material is the key to successful construction. This also applies to wooden structures. What we first pay attention to when buying it:

Decide in advance which timber to build a house from. A one-story house has enough material with a section of 150x150 mm. When erecting two-story structures, use a beam of 200x200 mm.

In the dacha version, use a simple planed bar, pre-dried in a natural way. A residential building needs a glued structure. A bar with a profiled joint, dried in a chamber, is suitable.

Attention should be paid to the quality of the product; it must have the correct symmetrical sectional shape, there must be no irregularities and curvature. Choose grade A or AB.

Use D-profile beams instead of rounded logs.

Conclusion

The choice of material must be determined at the design stage, taking into account all the situations that arise. You should not save too much by purchasing cheap material for a residential building in which you will live permanently. Modern quality wooden beams will allow you to build your dream home.
