Installing the timber vertically. Attaching timber to various types of foundations. How to properly attach beams to beams in different ways? How to properly fasten timber together

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:

1. Bottom harness.
2. Vertical fastening of frame posts.
3. Top harness.
4. Corner, no corner posts.
5. Fastening with corners.
6. Fastening timber using the cutting method.
7. Strengthening the frame.
8. 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) it will be necessary to add small parts to the frame, which is not 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 bottom trim, while 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

1. If the bottom trim is on nails or anchors, then the corner post is secured using a steel angle.
2. 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.

It is more convenient to join the beams of the upper frame 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 vertical installed timber(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.

How to prepare the timber joints, see below:

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.

1. When cutting corners of a building.
2. 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 V wooden house construction Two types of fastenings are used.

1. Fixing corners with remainder. Its most common varieties are: “in the cloud” and “in the bowl”.
2. 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.

1. 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 notch must be suitable in width to the perpendicular section of the 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.

1. 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.
2. 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 workers.

Butt fixation

This type of connection is the simplest and fastest. The bars are joined together. They are then 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

1. This fastening of the beams together is done with dowels, that is, wedges made of hard wood, so that the corners are strong.
2. Installation of inserts into the grooves of timber makes it possible to prevent its movement at the joints of the log house.
3. 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 fixing the beams “into the root tenon” is also called a “warm corner”. This type of connection effectively saves heat in the house.

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

1. 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.
2. 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.
3. It is very important that the elements of the locking connection fit together tightly. Thus, heat loss will be minimal.
4. 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.
5. 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.

1. Oblique castle.
2. “The tenon on dowels/dowels is longitudinal.”
3. "Half a tree."
4. "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 often 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.

Are you building a house or just need to secure a few beams together? Have no idea how to do this? After reading this article, you will learn a lot of ways to attach timber to each other (into a bowl, into a paw, end-to-end, with dowels, into a tenon, into a lock), as well as about their features, advantages and disadvantages.

Interest in environmentally friendly construction technologies has led to the fact that more and more often in the vastness of our country we can see classic wooden houses from a log house. This building warms severe frosts, and is constructed without single nail.

When building houses from timber, the fundamental factor influencing the final quality of the building is the connection of two links. The need to fasten the timber in a special way arises :

• at corner and T-shaped joints;
• when increasing the length of an individual link.

For each individual case, it is necessary to select its own type of connection, taking into account the structural features.

Important! The timber cannot fit perfectly against each other. Any connection breaks the tightness, so a layer of insulation and treating the joints with an antiseptic are mandatory measures.

Types of connections

The connection of timber differs little from the connection of logs, however, it has many of its own subtleties that significantly affect the work process. Corner splicing can be performed with or without a remainder, T-shaped and length extensions can be locking or simple. The connections are made vertically or horizontally.

All of the above options for nodes are divided into the following:

• end-to-end;
• in the paw;
• into a bowl;
• into the root thorn.

These options are used even in the construction of houses made of timber.

This type of connection is only applicable for corner options, is performed using the design of one-, two-, four-sided grooves. For such a joint, cuttings are made in the timber from the top or bottom side. The cutting is done in such a way that it is parallel to the cross-section of the material itself. This method is effective for simple, laminated and profiled timber.

This approach is recognized as one of the easiest and quick ways working with timber. In this case, the design includes two elements that are applied to each other and connected by iron plates. They are secured with construction staples or long nails.

Important! The success of butt fastening directly depends on the skill and experience of the builder. If you are working with timber for the first time or doubt your abilities, pay attention to other fastening methods. Errors in such fastening threaten you with loss of tightness, and as a result, heat loss in the room.

The preparation of such fastenings takes quite a long time and meticulously; you will need patience and a reserve of time. In this case, the main condition is the absence of significant shortcomings like cracks and wormholes. Fastening is carried out using a groove. It must be sawn ¼ on both sides of the beam. If you use a four-sided system, then cuts are made on all sides of the material. This design guarantees one of the strongest and most reliable connections.

Root Thorn

A tenon is cut on the beam on one side and a groove on the other. During installation, insulation (felt or cord) is placed in the groove, and only then the next element is placed on top of the previous one. It is necessary to cut out the elements for the main tenon with the utmost precision and accuracy, since this connection must fit as tightly and airtight as possible. Otherwise, a large loss of heat occurs.

Keys

Another popular method is fastening with dowels. These elements are wedges driven into a hole specially made for them for connection. So, the better and more accurately the preliminary work with the wedges is done, the more securely and firmly the beam will hold. Keys are divided into:

• oblique;
• transverse;
• longitudinal.

Splice

Another fastening option is splicing. This view is presented:

• simple;
• castle;
• T-shaped;
• elongated (in length).

Docking units when working with timber are divided into:

• simple;
• castle (into the castle).

For lock connections The following methods are typical:

• simple invoice (end-to-end and “into the wood floor”);
• invoice with a spike (“dovetail”);
• invoice with corner;
• lock with a cut;
• tension;
• "frying pan".

Locking units are designed to reduce shrinkage of the structure and make the structure more durable. They are even used when decorating a house made of laminated veneer lumber.

This type is applicable to all types of lumber when forming interior walls Houses. The T-shaped method is used when connecting vertical and horizontal wooden elements. To perform this type of splicing, the following joining methods are used:

• straight, symmetrical and root tenon;
• lock with groove;
• semi-, “frying pan”.

Important! Working with a T-shaped splice is not that difficult, and you can handle this task yourself. Prepare a set of tools in advance: jigsaw, wooden dowels, bars. This type connections are especially popular when working with laminated and profiled timber.

This method is used most often if the wall of the house has a non-standard length. For example, the width of the house will be 3.5 meters with a length of 11 meters. At the same time, the standard timber length is 6 meters. Splicing along the length will help you increase the missing meters. The following nodes are used here:

• “to the floor of a tree”;
• root or longitudinal tenon with dowels;
• oblique lock.

To strengthen the structure and add rigidity, it is additionally stitched with dowels or other fasteners.

Firmware is installed during the installation process. A groove is formed at the end of each link (the key has two grooves). The main thing is a tight connection and the presence of insulation.

Important! The half-tree method should not be used for load-bearing walls. An oblique lock, a root tenon or a swallow's nest would be the best options.

To connect the corners of the log house, two types of joints are used:

• “with the remainder” - go beyond the frame;
• “without a trace” - accordingly they don’t leave.

Fastening “with remainder”

A more expensive option, as it requires more material consumption. However, its advantages include not only attractive appearance, but also heat capacity and enhanced corner protection. The best proven method is fastening “in the tail”. A groove with a protrusion is made in the first block, which is located across the cut. In the second there is a groove that corresponds to the cut of the first.

Fastening "without residue"

This type of fastening is performed in the following ways:

1. "Into the bowl"- bowls are cut out of timber manually or using a special bowl cutter. Some specialists prefer to use a mobile cup cutter, processing the timber directly on the site. After cutting, the elements are stacked one on top of the other in bowls. Be sure to place felt or jute insulation between them.

2. "In a big way"- this connection is similar to the one described above, the only difference is that the bowls are cut out not from below, but from above.

3. "To the brink"- the most complex and tricky corner connection. To do this, notches are made in the block on both sides. This type of fastening is similar to a “claw” fastening, however, here the end of the beam is removed, which allows you to arrange a corner without a protrusion. The elements are connected using dowels. The main disadvantage of this connection is low wind resistance. To eliminate this error, a straight cut is often replaced with a trapezoidal one.

Conclusion

Remember that any type of connection is a controversial issue, because it must be selected for each isolated case. For example, according to GOST, profiled timber can be connected in length only according to certain parameters - T-shaped and at the corners. Also, not everyone will be able to independently make one or another connection method, since some of them are quite difficult to implement. The best way out in this case, trust professionals who are able to work on wood with high precision.

Should you finally throw away your old wood floor?

During operation, deep cracks do not form in the laminated veneer lumber and the entire thickness of the laminated veneer lumber “works.” Therefore, in terms of thermal insulation, laminated veneer lumber is significantly superior to concrete and brick; its thermal conductivity is lower.
Layers of glue in laminated timber are good heat insulators, and finger joint The timber creates several sealing contours between each other and makes it impossible for cold air to penetrate into the room. In addition, when drying, ordinary timber cracks (bursts), these cracks significantly reduce the working thickness of the timber. From all this it is clear that laminated veneer lumber is much warmer than usual.

It is believed that the main shrinkage occurs in 1…2 seasons. Regular timber When dry, it shrinks by about 10%. In the third year, shrinkage can be 0.5...1%. This dramatically worsens the quality of construction and thermal insulation of the room. It turns out that windows and doors cannot be installed during the shrinkage process, otherwise they will warp. How to dry the timber without installing windows, doors and heating?

When building a house from laminated veneer lumber, shrinkage is only 0.4%. Glued laminated timber shrinks mainly during the construction of the wall. One of the most important parameters is wind insulation. Glued laminated timber does not require laying insulation, sealant, packing, etc. Our profile, consisting of small grooves, guarantees 100% wind insulation.

How to properly fasten timber

Since ancient times, strong wooden houses have been built in Rus'. They built, as they say, “without a single nail,” but soundly and to last. And in our time, especially paving stones are held in high esteem. The timber fits well in rows and exhibits slight shrinkage, and the principle of operation “without a single nail” is more relevant than ever.

How to fasten the timber

Instructions like skre drink timber

1 Only parts are nailed together, not walls, since the nail holds the structure tightly. The connection of the timber in the wall should not, and cannot, be a rigid structure. A certain mobility is provided here, because the tree either gains or releases moisture throughout its life. In addition, nails rust over time and damage the wood.

2 If you still decide to save time and money and fasten the timber with nails, then at least use special nails without a head (for example, 6-piece wire) and be sure to press them down. The top beam is first drilled through with a regular drill.
Here you need to remember that the stingy pays twice: in a bathhouse built on nails you will have to caulk the cracks every now and then.

3 Usually the timber is fastened wooden dowels. Dowels are square bars 18x18 mm. Length varies depending on (no more than 25 cm). Special drill make holes with a diameter of 21 mm and drive dowels into them, which should be located

in a checkerboard pattern. Drill through the beam.

4 It is good to use round wooden dowels with a diameter of up to 3 cm for fastening. The main function of dowels is to prevent horizontal movement of the beam relative to each other. The dowels are placed one above the other so that 3-4 rows can be fastened at once. When installing dowels, keep in mind that the hole for the dowel must be positioned strictly vertically, be no smaller in diameter and have sufficient depth. The wooden dowel is quite elastic and prevents the wood from being crushed in the hole.

5 There is another way - using the “Force” spring unit. By its design, it is a screw with a built-in compression spring. This system allows you to eliminate gaps between parts, pressing the beams against each other with enormous force. The “Force” spring unit is used mainly for balanced shrinkage of the crowns of a structure, preventing deformation and cracks. True, this method is quite expensive.

Construction and features of houses made of laminated veneer lumber

How to fasten timber together

For the production of laminated veneer lumber, boards are used as material coniferous species without defects or flaws. The board is processed under soft conditions up to relative humidity 8 ±2% in drying chambers. Then the boards are planed on 4 sides to exact dimensions, sorted and glued together using a powerful hydraulic press. The number of lamellas can be from 2 to 5, this allows the production of laminated veneer lumber (synonyms: laminated veneer lumber, multi-layer laminated veneer lumber) quite strong.
The thickness of laminated veneer lumber reaches 200 mm. To glue together parts of laminated veneer lumber (lamellas), special adhesives are used, which are not only environmentally friendly, but also highly durable. These adhesives allow the wood to “breathe”. The gluing quality complies with international and Russian standards. When gluing (using the technology of manufacturing laminated veneer lumber) into a single beam, the direction of the wood fibers and annual rings in the lamellas is placed in directions opposite to each other. This method makes laminated veneer lumber stronger than regular laminated timber. Glued laminated timber does not change shape under the influence of humidity (it does not “drive”). One of main points When producing laminated veneer lumber, it is profiled on special four-sided machines. With this technology for manufacturing laminated veneer lumber, the quality depends on the accuracy of the tongue-and-groove joint. After giving it a profile, the laminated veneer lumber is cut into the required lengths (cut to size). Then the laminated veneer lumber is processed on special cup-cutting machines - the crown cups are “cut” and holes are drilled for the dowels.

An integrated approach to management production process determines high quality products. Thanks to the use of modern computer technologies, all stages of construction from design to manufacturing of a house kit are closely connected with each other. High precision wood processing is ensured by the use of high-quality equipment, which the best way affects the build quality. Glued laminated timber is made from coniferous wood (including larch and cedar).

The thickness of laminated veneer lumber depends on climatic conditions the area where your home will be located. The windproofness of the walls is ensured by the ridge connection in the locks along the profile of the laminated veneer lumber. The company offers construction of houses according to standard projects for every taste, and for individual orders. Our designers are ready to design “any whim” of the customer, and experienced builders bring it to life.

The main advantages of houses made of wooden beams

Advantages of building houses from laminated veneer lumber

Glued laminated timber surpasses all other wooden structures in durability. Houses made of laminated veneer lumber have superior characteristics compared to other types of houses. Homes from solid log with a humidity of at least 30%, it forms cracks when drying, and the moisture content of laminated veneer lumber is 8...12%. Therefore, wooden cottages made of laminated veneer lumber do not have a tendency to cracks. Construction period wooden house from laminated veneer lumber is much less than from solid wood. All parts, including beams and rafters, are manufactured in the factory with high precision. Thanks to the high-precision equipment on which the wood is processed, the laminated material is different high quality surfaces. Due to the absence of internal stresses, laminated wood retains its parameters over time, does not bend, twist, or shrink. Big advantage laminated timber - no need interior decoration cottage The absence of finishing costs significantly reduces the cost of building a house from laminated veneer lumber, by an average of 50 percent or more.
A house made of laminated veneer lumber practically does not shrink. Glued laminated timber is not exposed to any viruses, fungi and bacteria due to optimal humidity. In a house made of laminated veneer lumber, the air quality is ideal for people prone to allergies, pulmonary and heart diseases. In people with hypertension, positive results are observed in reducing blood pressure. The resorption of hemorrhages is accelerated, metabolism is normalized, and the incidence of migraines and neuroses is reduced. Houses made of laminated veneer lumber do not require a deep and heavy foundation, since they are lighter than brick and stone houses.

Environmental friendliness of laminated timber housing

Glued laminated timber is made from wood - natural material. It is warm to the touch and maintains comfortable humidity in both winter and summer.

Environmental friendliness is the main advantage of laminated veneer lumber relative to concrete, foam blocks, and bricks. Many people claim that wood “breathes”. This is not entirely true. In reality, air cannot penetrate from the street into the house and from the house into the street. wood regulates room humidity. wood has antiseptic and antitoxic properties.

The most reliable and proven building material for building houses is wood. Timber is the most commonly used of all wooden building materials. A building of any complexity can be erected from natural, durable and at the same time soft wood. But if during construction the beams are not properly fastened together, then such a wooden house will not last long and may even pose a great threat to residents, because it can fall apart at any moment from even a slight mechanical impact on the walls. Therefore, the fastening of a wooden house from timber and the selection of fasteners for this process must be approached responsibly and seriously.

Features of wooden material - timber

Before starting construction, many are faced with choosing the main building material logs or beams. To do right choice you need to know some of their features.
The characteristics of logs and beams are equal: they are warm, frost-resistant, can withstand winds, and provide good air exchange in the room. But to lay walls made of logs, you need to have certain skills in working with this material, or it is necessary to construction site there was a professional. If there are none, then the construction of the house will fail.

Timber is a wooden material that has passed through special machine, which gave it a certain shape with equal and perfectly smooth surfaces. Due to which the appearance timber house is perfect without any additional finishing works. It is easier to work with timber; beginners and non-professional builders can cope with the construction of a log house from it. Shrinkage of a house made of timber occurs faster than that of a log. Distinctive feature such wooden log house are more ventilated interventional seams. But you can cope with them by using high-quality insulating materials.

Materials for fastening timber together

Fastening elements for use in wooden house construction are available at construction markets enough large assortment. The following elements are most often purchased for fastening the crowns of a log house:

1. Regular nails.

But not all of these materials are suitable for wooden houses. Many people choose fastener at random, without even knowing how best to fasten the beams together.

Durable reinforcement is used to make metal dowels. They are intended to ensure good fastening of the crowns of a log house made of timber or logs to each other. They are durable and can prevent deformation wooden material. But it is still not recommended to use metal dowels in the construction of a wooden house.
Metal dowels have a corrugated surface, which can lead to damage to the structure of the wooden material during its movement. Metal and wood are not compatible, they are completely different. The metal dowel, being inside the beam, will soon undergo corrosion due to temperature changes, humidity and condensation formed on it. Dowel rust can cause premature deterioration of the wood material.

Wooden dowels are made from hardwood, mainly birch. Therefore, they are not inferior in strength to metal fasteners, but at the same time they are better suited wooden house. Birch dowels ensure uniformity of the walls of the house and prevent deformation of the timber. They are not afraid of temperature changes, humidity and other unfavorable factors.
Birch dowels are very durable and available in financially. These fasteners can be either round or square. It is easier to prepare holes in the timber for the first type of dowels.

This fastener is made of high-strength metal, and most importantly it does not corrode. It consists of bolt, spring and wood thread. The average size of the spring unit reaches 25 cm. The “Strength” spring unit ensures the strength and stability of the entire wooden structure, preventing torsion and deformation of the beam. Also, this fastening element provides additional load to the crowns of the frame, thereby preventing the formation of cracks and gaps during its shrinkage. The load from one spring unit is about 130 kgf, and about 4 of these elements must be installed on the entire beam.

Using nails, you can firmly fasten together many various parts and designs. Some builders also use these fasteners to build wooden houses from timber, but this is a big mistake. Nails quickly rust while inside the timber. Due to corrosion, wood material deteriorates. And the structure of the house itself may unexpectedly crumble. After all, a rusty nail will not be able to withstand the load that the walls of a house made of timber will constantly provide it with. For the same reason, you should avoid purchasing metal staples. If, despite this, you decide to use nails, then it is better to purchase special wires without a head, the diameter of which is about 6 mm.

To build a wooden house and fasten the beams together, it is better to use birch dowels or Sil spring units. These fasteners are capable of providing strong and durable fastening of log crowns. In order to save money, you can secure the upper rims of the log house with “Strength” spring units. This method also provides additional necessary load to the crowns. The lower beams can also be secured with dowels; the weight of the upper crowns and roof is distributed on them. It is not recommended to use nails and metal dowels to fasten timber together, especially if you want to build a strong, safe and durable wooden house.
