Fastening wooden blocks to each other. Types of timber fastening

High-quality connection of beams to each other during the construction of a house is of no small importance. The reliability of the entire structure and the preservation of heat in the house largely depend on the method and accuracy of the connection.

The strength and thermal insulation characteristics future design.

Construction wooden houses With new technologies for manufacturing timber, it has become rapidly gaining popularity. Ecologically pure material with good thermal conductivity and attractive appearance, it is ideal for the construction of residential buildings and other buildings in any region of our country.

The most important stage in the construction of wooden houses is the jointing of the beams with each other. Highly specialized equipment for making tenons and grooves is used only in large industries, due to the high cost and large sizes. However, connections of profiled timber can be made with your own hands.

Necessary tool for making connections

Figure 1. Types of timber connections.

When making connections yourself, you can use conventional hand-powered tools available from the developer or specialists, such as:

Chainsaw with petrol or electric drive. Can be used manually circular saw with an electric drive, but the maximum permissible cutting depth of the device must be more than half a tree.
Set of chisels. In commercial enterprises it is not always possible to find a tool of the required length and strength, so it is advisable to make it yourself or order it from a blacksmith.
Hammer, mallet, axe.

In the old days, cutting corners was done with a single axe, but it was time-consuming. Modern instrument with various types drive will significantly facilitate work and reduce time spent on work.

Basic methods of connecting timber during installation

At the connection point, you need to choose a specific method that guarantees optimal strength and tightness of the joint. Corner connections can be made:

with ends protruding beyond the main dimensions;
without protrusions;
butt laying, when the beams do not overlap each other;
T-shaped connection for walls inside the building.

Figure 2. Construction of a rectangular root tenon.

The technology of the method with a remainder provides best quality corner connection, but requires more material consumption. Each beam produces from 0.4 to 0.6 meters of wasted length. With a height of 15 crowns, the total unused length will be from 20 to 36 m. With a beam length of 4 m, this will amount to from 5 to 9 additional products. You can see the corner connection with protruding parts in Fig. 1a.

The first crown in a building is usually placed in a joint with a key groove with a specific name for the joint - “oblo”. This method is used for any method of laying material, with or without protrusions. The sampling is performed at half the thickness of the product. The articulation of the corners of the house without protrusions can be seen in Fig. 1b. To prevent displacement in the main planes, subsequent crowns must be joined using the “root tenons” type with the installation of dowels. The design of a rectangular main tenon is shown in Fig. 2.

Nagel represents wooden block round section 25 cm long and about 30 mm thick. In the beam laid on the cushioning material, you need to drill a hole with a depth exceeding the length of the dowel by 20-40 mm, and hammer the part into it.

Butt jointing of corners is the most in a simple way. The quality of such joints is extremely low; creating a warm corner in this way is unrealistic. The timber is fastened with such joining using metal brackets with spikes, nailed down. Laying timber end-to-end is shown in Fig. 1st century How to fasten a beam with a metal bracket can be seen in Fig. 1e.

Figure 3. Dovetail.

T-shaped connection of capital and internal partitions has several options:

joint using a key groove;
“groove-tenon” joint in the form of a symmetrical trapezoid;
“groove-tenon” joint in the form of an asymmetrical trapezoid with a right angle;
use of a rectangular mortise-tenon joint.

Spikes in the form of trapezoids are designed to maintain the connection during loosening of the structure and efforts aimed at pulling apart different sides. The design of such joints is complex, but also more reliable. Because of appearance the connection was called " dovetail" The structure of such a joint can be seen in Fig. 3. Making a dovetail requires care and patience in fitting the surfaces.

The connection can be assembled and disassembled only by moving the products in a vertical plane.

Many craftsmen prefer to fasten walls using rectangular tenons. T-joints are often fastened with special brackets, long bolts and washers. large diameter or nails. An example of a right-angle tenon connection is shown in Fig. 1 year

Longitudinal material connection

Figure 4. Butt and overlay joint.

One of the main disadvantages of timber is its length limitation. The standard dimensions of manufactured products range from 4 to 6 m. For long walls or when using scraps, it is necessary to make a longitudinal connection. Such connections are undesirable in the construction of capital walls due to possible deformation. If it is necessary to install longitudinal joints in several rims, they cannot be placed in adjacent rims along the same vertical line. For interior walls There are no restrictions on merging timber due to a more stable temperature regime.

When splicing timber along the length, use a central tenon or various joints with a lock. The straight lock is most often used due to the simple manufacturing process. Samplings are made in the timber to the extent of half the thickness of the timber. The resulting surfaces are available for processing and can be carefully adjusted.

A beam connection that is reliable against displacement can be obtained by using a central tenon. The nest needs to be made a little longer thorn. The length of the tenon should be twice the width of the beam. To connect more firmly, you can install two spikes.

Extension of the beam can also be done with an overlay. The overlay connection can be oblique or straight. Types of connections can be seen in Fig. 4. The ends of the products must be given the selected shape and placed in place. Subsequent crowns will compress and secure the connection with their weight. When lengthening timber in main walls, it is advisable to use a combination various fastenings. Products fitted to the overlay connection must be additionally secured with one or two wedges. A view of a wall with spliced timber can be seen in Fig. 1d. All connections must be sealed with sealing material.

Making corner joints of timber at an indirect angle

In building structures there are always corner joints of timber, the size of which does not correspond to 90°. On most buildings, such corners are located in the attic part of the room. Their size depends on the slope of the roof. Corners on main walls various sizes may occur when installing protruding or recessed elements.

It is advisable to make joints at an obtuse or acute angle using the “groove-tenon” principle. Protrusions and recesses are cut out at the required angle, and their surfaces are adjusted accordingly. To increase strength, you can use additional fastening with bolts, screws or nails of the required length. If the thickness of the products is large, you need to use metal brackets of the required shape with appropriate fastening.

When making a large number of identical joints, it is advisable to make special marking templates that will speed up and facilitate the process of applying markings for connecting logs in a log house.

For templates you can use tin, plywood, thick cardboard, thin plastic. When making joints, you should first make a cut in the desired position, then remove areas inaccessible to the saw with a chisel.

Ready-made building designs offered by manufacturers building materials, equipped with profiled timber with connections. All types of tenons and grooves are selected based on the required strength and are manufactured using industrial equipment with high accuracy.

One of the main stages in the construction of a timber building is the assembly of the log house. Before you start construction, you need to know how to properly fasten the timber.

Otherwise, there can be no talk about the quality of work.

The need to connect wall elements appears in the following two cases.

When cutting corners of a building.
If you need to increase timber when its length is not enough.

Methods for fastening timber are varied. They are selected based on the specific situation.

Types of corner fastening

The methods of attaching timber to each other during the construction of log houses differ significantly from joining log analogues. In our technological age, ancient methods of joining lumber are gradually modified.

On this moment In wooden house construction, two types of fastenings are used.

Fixing corners with remainder. Its most common varieties are: “in the cloud” and “in the bowl”.
Fasteners without residue. Its most popular subtypes are “in the tooth” and “in the paw.”

Connecting the corners of a log house “into a bowl”

The timber is connected “into a cup” thanks to the locking grooves.

There are several varieties of them: one-, two- and four-sided.

With the first type of lock, a perpendicular groove is made in each of the beams using a notch. It is cut through one of the sides, usually the top. This file must be the same width as perpendicular section timber.

Note!
For the most part, house-building companies use this particular fastening technology for profiled timber.
This happens due to the fact that for the manufacture of such grooves it is necessary minimum costs time and effort.

The methodology for creating the next type of mortise locks involves sawing timber from both sides, in other words - from below and from above. The depth of perpendicular cuts is approximately a quarter of the height of the beams.
The connection is very high quality. However, it requires high qualifications from carpenters, otherwise they may cause chips or cracks when cutting grooves and laying beams.
The four-sided locking fastening for the timber is cut out from all its sides. This method of fixing corners makes it possible to construct log houses that have increased strength and reliability. Grooves on all sides facilitate the installation of walls, since their crowns are laid like a construction set. This method requires very high professionalism from employees.

Butt fixation

This type connections is the simplest and fastest. The bars are joined together. Then they are secured using studded metal plates, secured with staples or nails.

In this case, the strength and density of the resulting corners mainly depends on the skill level of the carpenters. It is necessary to carefully adjust the ends of the combined beams, since their absolutely flat surface is necessary. However, even experienced craftsmen do not always cope with this task. The corners are not sealed; in addition, they experience regular perpendicular loads.

Note!
Although this type corner connections and the fastest, its quality is minimal.
Heat losses through such angles are very large.
Therefore, it is best not to use end-to-end fastening of beams in the construction of residential buildings, but to use other, more complex types connections.

Corner joints using dowels

Such fastening of the beams to each other is done with dowels, that is, wedges made of durum varieties wood so that the corners are strong.
Installation of inserts into the grooves of timber makes it possible to prevent its movement at the joints of the log house.
Please note that the strength of the corners depends on the type of wedges. They can be longitudinal, transverse or oblique. The latter type is difficult to manufacture, but its use produces the strongest corners with low thermal conductivity.

Warm Corner Castle

It is not for nothing that the fixation of beams “into the root tenon” is also called “ warm corner" This type of connection effectively saves heat in the house.

Therefore, it is very popular in the construction of cobblestone buildings.

The basis of the technology is as follows: in one of the combined beams, a groove is cut with your own hands, on the other, a tenon is cut out, having dimensions corresponding to the groove.
When constructing a log house, it is laid in the groove recesses. You can use linen, jute fabric or felt made from the same raw materials.
It is very important that the elements lock connection fit together tightly. Thus, heat loss will be minimal.
To increase the strength of the log structure, alternate tenons and grooves in the corner rows, and fasten them with additional round ones made of wood.
When using dowels, undercuts, fat tails and other “groove/tenon” type fasteners in connections, be sure to leave vertical slots between the elements of the lock. They are needed to compensate for wall shrinkage.

Half-tree fastening

Another simple type of cutting corners is “half a tree”. This name has stuck among professionals due to the fact that it creates cuts that cover half the thickness of the timber. Assembling a log frame with this method begins with drilling holes for dowels or dowels at points near the corner joints.

Before attaching the timber to each other, calculate the length of the dowels so that it is enough for several rows. There are also more modern variety of this connection. With it, dowels are added to corner joints to increase their strength and heat capacity.

Dovetail

The most reliable, durable and minimal heat loss method is the T-shaped dovetail notch. It is similar to a “root spike”, only the protrusion is not rectangular, but trapezoidal. The grooves are given the same shape. It should be noted that the price of such a cut is quite high.

At the moment, the following subtypes of T-shaped timber connections are known:

locking grooves on insert tenons;
symmetrical spikes in the form of a trapezoid, called “frying pan”;
rectangular spikes called “half-squash”;
asymmetrical trapezoidal spikes - “blind frying pan”;
a straight groove on the main tenon; in addition to the log house, it is also used to fasten the imitation timber.

There is another subtype of this fastening: “in the paw”. With it, horizontally located recesses and grooves in the form of trapezoids are cut into the beams. They should fit each other perfectly. Since such sawing is quite difficult to carry out, this type of cutting is rarely used.

Longitudinal connection methods

When constructing large buildings whose length exceeds standard sizes beam of 6 meters, it becomes necessary to fasten two beams along.

In this case, the instructions allow the use of one of the following types of connections.

Oblique castle.
“The tenon on dowels/dowels is longitudinal.”
"Half a tree."
"Longitudinal root tenon."

This raises the question of whether it is possible to fasten the timber with reinforcement or other metal fasteners. It is possible, although this is practiced less frequently than using wooden fasteners.

The fastening of the beams with the help of tenons and dowels is quite strong. For such a connection, cuts are made for identical grooves at the ends of the two beams. Next, they are laid flush against each other, then a wedge-shaped insert made of hard wood is driven into the groove.

Dowels can also be made of steel. Their shape is different - there are trapezoidal, prismatic, rectangular, toothed and even inserts.

Longitudinal building of lumber “in half a tree” is similar to similar fastening of corners. The ends of the joined elements are cut to a width that is half their thickness. The strength of fastenings is increased by using dowels.

They can be replaced with staples, large nails or fastening plates. This type of connection is fast and simple. However, its strength is not enough for the load-bearing (external) walls of a large cobblestone building.

When connecting into longitudinal main tenons, a groove is cut out on one of the ends of the beams, and a protrusion on the other side. To increase the strength of the fastening, it can be made trapezoidal. This way you will eliminate horizontal movements of the beams in the log house.

When building a house with your own hands using timber, you need to know almost everything about how to attach timber to timber. Here are the most basic mounting methods:

Bottom harness.
Vertical fastening of frame posts.
Top harness.
Corner, non-corner posts.
Fastening with corners.
Fastening timber using the cutting method.
Strengthening the frame.
Attaching ceiling beams.

Before starting work with timber, it is necessary to ensure that all materials and the area where construction will take place are prepared.

Features of working with timber

the timber for the frame must be dry; if it is not dry, then after installation the frame is immediately covered with OSB timber;
treat all material with a special antiseptic;
prepare the necessary fasteners in advance;
Before purchasing timber, be sure to accurately calculate required size sheathing frame, if this is not done, then with an increase in thickness (unplanned) you will need to add small parts to the frame, which is not a good start when building a frame base.

The lower piping with timber is done according to the principle of laying on a grillage (roofing material is pre-laid).

Before tying, it is necessary to cover the foundation with roofing felt (a cheap one will do) or film, otherwise the timber will be damaged (when construction has been frozen for several months).

If you don’t have roofing felt, you can cover the foundation with a regular film, which will protect the concrete from moisture and the formation of concrete milk. When the foundation is ready for laying the timber, check the plane of the grillage with a level to make sure it is perfectly level. The timber required for the lower trim is placed on this surface, and the beams are joined using the sampling method at the corners.

The sample can be half a tree or a paw. The half-tree option implies an even cut of half the thickness of the beam (for connection with another beam). The option of fastening into a paw involves a cut at an angle of 45% from the middle of the beam to the lower end (or upper, depending on where one of the beams will be when fastening).

When fastening the timber according to the principle of angular fixation, one of the following options is used:

anchor connection;
fastening with nails 150mm;
fastening using a wooden dowel.

The dowel should be made of dried oak, with a protrusion above the surface of the timber by 6-8 cm, the diameter of the dowel is always equal to the diameter of the hole for fastening. Before fastening, the beams are checked: they must be equal diagonally and at angles.

With the bottom trim, the timber is attached to the foundation using nuts and wide washers. The washer improves fastening to the foundation because it increases the adhesion plane of the two surfaces. The nut is selected on a turnkey basis - hexagonal, other options are not suitable.

When the beams of the lower frame are connected with nails or dowels, a corner anchor is not required. If the corners were secured differently, without dowels or nails, then the first anchor is attached to the corner at the place where the beams connect.

Vertical racks frame structure installed after the process of bottom tying of beams is completed. When working on installing racks, they start with corner frames.

Mounting options

If the bottom trim is on nails or anchors, then the corner post is secured using a steel angle.
After attaching the lower trim with a dowel, put the corner posts on the remaining 6-8 cm outlets.

Fixation of non-corner posts is done in two ways: by cutting out, using steel corners. The corners hold the structure more reliably; they have only one drawback - cost. The corners themselves are attached to the beam using self-tapping screws. The cutting method involves fastening using a special recess having a depth of 50% of the thickness of the lower trim. Example: if the timber is 80 mm thick, then the cutting depth will be 40 mm.

Non-corner posts must be fastened with jibs, which hold the structure and prevent it from loosening. The jibs are needed until the top frame of the structure is completed with beams, after which the jibs can be removed.

Bars top harness It is more convenient to join in a cutting area or using galvanized steel corners. If the cutting method is chosen, then it is necessary to make precise markings for cutting on each vertically installed beam (rack). The grooves of the upper trim must coincide with the grooves of the lower trim, otherwise you will end up with a skewed structure that will gradually fall apart on its own.

Increasing the length of lumber using a “bias lock” is the most complex method. However, it gives the fastening highest strength and reliability among all described methods.

The angular and longitudinal connection of timber, as well as fastening - imitation timber, is a very important component of building a house. They need to be approached extremely seriously. The strength of the building being constructed and the quality of its cladding depend on this.

In the video presented in this article you will find Additional information on this topic.

Wood is considered one of the highest quality and most reliable building materials. The naturalness and “softness” of wood make it possible to build very good buildings. But if construction crew treats the quality of fastening irresponsibly, then such a house, not only will not stand for a long time, but can also pose a threat to its owners. Therefore, it is very important to know how to fasten the beams together correctly.

Reliability wooden house depends on how the beam will be attached to the beam.

Some features of timber

It is believed that the customer is always right, but many builders begin to impose their opinion. And then disputes may arise. One of these controversial issues is the choice of timber or logs. In order to answer this question, you need to know some characteristics of these materials.

The logs have very high frost resistance and provide good wind resistance, preventing the formation of drafts from cracks. But creation log walls- a very difficult job that requires knowledge and skills, and even better, a highly qualified carpenter. Self-production a log house threatens to lead to failure. Assembly of logs is step by step process, because after cutting they are given time to shrink and only after that they are installed.

Timber is the same wood, only already mechanically processed in production. Its thermal conductivity properties are similar to logs. The only thing is that the connecting seams of the beams are more breathable. But they also found a way to deal with this problem: you need to use alternating beams with different heights. Thus, the seams are reduced, and as an addition, special cushioning materials and insulation are used.

When constructing walls from timber, the need for meticulous work is much lower. This means that, in addition to a professional, both a beginner and an amateur can cope with this task. A very great convenience is that the timber has minimal shrinkage. Therefore, it is almost immediately laid out on the foundation.

If we objectively evaluate logs and beams, then in the second case the time for construction works you need 2-3 times less than in the first one. This significantly saves time, financial and human resources.

Principles of correct timber connection

Since the corner connections of a timber building are quite weak point, then to eliminate this drawback, all kinds of insulation are used. For this purpose, there are several types of connections, not only for the corner, but also for internal walls, rafters and beams.

Each place has its own purpose, therefore, in order for the entire building to fulfill its functions, it is necessary to correctly fasten the timber in all places.

For corner beams joints such as butt joints, with or without remainder, have been developed. WITH inside use a T-shaped connection.

Longitudinal fastening of the timber is ensured using dowels, a main tenon, an oblique or straight lock.

For such a material, this connection provides maximum strength and reliability. To make your work easier, you should act according to a specially designed template. The main thing is to maintain the evenness of the lines and make sure that the bars fit snugly against each other. As already mentioned, corner joints are additionally insulated.

Choice also plays an important role. the right tools. For example, without an ax there is no point in taking on a log house. The saw, hacksaw, hammer and mallet act as auxiliary forces.

The most common joint for corners is the joint with the rest and the keyway. The size of the groove is oriented to half the thickness of the wood. This type is mainly intended for the first crown.

The "lock" can also be used for residue-free connections. For these purposes, it is necessary to have dowels with a cross-section of 30 mm and a length of 25 mm. The timber is laid on tow, and then holes are prepared for the dowels. At this stage, it is important to compare the height of the beam and the depth of the aperture. The second should be 1.5 levels higher than the length of the log.

Beginners most often build using butt joints. Of course, this method is the simplest, but it has many nuances. Firstly, with this option, the structure is vulnerable to wind; accordingly, drafts will constantly blow in the house. This means that the heat will not stay there for long. Secondly, during frosts the building will cool down greatly.

IN this option the connection of two beams with metal plates and nails with spikes is provided. Two elements are stacked on supporting part, after which both ends are fastened with staples.

The T-joint requires dowels. Thus, the most reliable fastening of all available. Additionally, connections with a key and straight groove, as well as a symmetrical or rectangular trapezoidal tenon can be used. The latter help to hold the joints together so that they do not become loose or come apart. Of course, in order to make such a spike, you need to be patient and time. Therefore among professional builders he is not that popular. But the dowel is another matter. Connections in the corners are strengthened with staples, bolts and nails.

Advantages of properly fastened profiled or laminated timber

Despite the fact that wood has been used in construction for a long time, it also has a number of “inconvenient” features. Firstly, the surface of the wood is not perfectly smooth. Secondly, while working with it it turns out a large number of burrs and knots. If the material is not handled correctly, it will be too vulnerable to cold winds, which will significantly affect the quality of living inside such a building.

A rope is passed through the holes and secured at the ends with knots.

Exactly the right technology timber production made it possible to eliminate these disadvantages. A prominent representative of such a “struggle” is profiled timber. Ready material has special depressions and ridges on its surface. They provide a tighter joint and, accordingly, more high quality connections. Considering the profile, the methods for joining profiled materials are similar to ordinary timber.

To be fair, it is worth pointing out right away that the cost of such material is quite high, since the consumption of wood during the production process is very high.

Therefore, more preference is given to the glued analogue. Such timber consists of lamellas separately glued together, which lie in fibers that do not coincide with each other. Such material is initially honed to smooth surface, is impregnated with special solutions that will protect the house from rotting and fungi.

Profiled timber has good fire resistance, similar to metal structures. The glued analogue is lighter, which allows you to significantly save on laying a heavy foundation. But again, preferences depend on the individual wishes of the customer.

Wood has a very bright and unique structure, thanks to which buildings made from it look truly interesting and attractive, most importantly, original.
