The connection of the bar to each other: ways, technologies. Profiled beam

Wooden beams are now increasingly used for the construction of bathhouses, dachas and houses. This is due to the fact that the material with a larger cross-section becomes more qualitative and can compete with a log. When erecting walls, reliable fastening is of particular importance.

Using a profiled beam provides a lot of effort and time, ease of assembly. This technology has little difference from the log cabin. But installation and finishing are much easier and faster, and this material in many regions is more affordable. Joining the bar together is one of the most important steps on which the strength of the structure depends directly.

Key points

When constructing walls, the task of joining occurs in two cases: when the material is stretched (interwoven) along the length and the bunch of corners of the building. Docking the beam in the corners is most important. During its implementation, a bookmark is made for the reliability of the house, its dimensions, design and wall quality.

There are two types of connections: no residue and with a remainder. The latter is based on the fact that the end faces a fixed length for the place of the corner fastening. The peculiar wooden warming of the angle, especially noticeable during the wind, is the main advantage of this method. In addition, due to this performance, an original design is created, which has its connoisseurs.

Under the plexus without a remainder is meant the arrangement of the ends at one level with the plane of the wall. The main advantage is to save construction materials and reduce the size of the building.

For any type of product, the connection rules are general, it can be a profiled or glued bar 150x150, dried or with natural moisture. During the installation of the log house, the same method should not be used. Different elements of the structure have their own binding technique. During the purchase of materials it is worth remembering that the samples for good warming should have a different size, in particular the parameters of the section.

Instruments

In order to connect the beam with each other with your own hands, a mechanized normal tool that many have is quite suitable:

• Set of chisels. In stores, despite the extensive choice, it is not always possible to find a tool with the necessary parameters. Solve the problem by ordering it from a blacksmith or by doing it yourself.
• Chain saw with electric or gasoline drive. If it is not possible, a circular saw with an electric type drive can be used, but the device must have a maximum depth of cut not less than half a tree.
• An ax, a hammer, a hammer.

Carried out the cutting of corners earlier with the help of an ax, but this took a lot of time and energy. Thanks to modern tools, time costs for work are reduced and work is simplified.

Types of joint timber

Grooving a rectangular shape is the most well known method of joining. There are three varieties of such a plexus, the simplest of them is a one-way connection. In this case, a rectangular small groove is cut out on the side. The two pieces to be joined must have identical groove dimensions. Their size corresponds to the width of the material used, the depth is half the height. The sides of the beams during the docking of the groove in the groove must be on a single plane without protrusions. The length of the remainder is determined by the distance from the beginning of the groove to the end of the beam.

Another option is a two-sided plexus type. The groove must be cut at two edges opposite to each other. Its depth should be equal to ¼ of the height of the bar itself. Provides such a timber assembly quality installation.

Four-sided binding is the cutting of the groove on each face. In this case, the upper and lower grooves should have a depth of ¼ of the height of the bar. The limiting density of joining the beams is provided by this method.

Docking on root spikes, special dowels and cutting the butt bar are considered the most popular connection options without a residue. The last one is the easiest, but unreliable. The end of the bar in this case rests against the other side (they change places further). Metal brackets are used to fasten the beam or nails. With this installation, pressing the butt is poorly controlled, this affects the quality of the post-processing and the provision of a perpendicular arrangement of the nodal elements. Justified this method for the construction of small economic buildings.

Variant "vpolderova" is more reliable, it uses the overlap of the bars, at which they are drilled at their ends with a length corresponding to the width of this material. The ends of the bars, therefore, are wedged into each other. By means of fasteners the point of connection is strengthened.

Root Thorns

This technique is based on the creation of studs and nests, suitable for them. In the center of the butt on the edge of one element for the connection, a spike is cut out. Equals its length to the width of the material. On the other bar, respectively, a groove is formed with a size suitable for the stud. During the docking of the groove in the groove with effort, the thorn is driven. Most often with the purpose of warming the corners before fixing, llodzhut material is laid.

The "dovetail" connection is one of the options for such a docking. The produced spike in this case has a trapezoidal shape that expands outwards. The groove has a similar shape. This joint is more reliable and denser.

An absent spike for securing

In contrast to the root variant, it has a vertical arrangement. Such a spike when connected is on the inner wall surface. A transverse matching groove is formed on the lateral plane of the other beam. The connection of the bar to each other is to dock with the spike.

Extended lengthening keys for joining timber

A special method was the combination of fasteners on spikes and butt-joints. At the end of one bar in this version, a keyway is produced. A similar element is formed on the side of another bar in the transverse line. Each beam rests on the next. The entire length of the grooves inserted wood key. It is a square whose side dimension is a third of the total width. The key is mounted in such a way that in one bar there is one part, in the other - the other. It can be inserted in a horizontal and vertical way, the latter is more common due to the simplicity of manufacturing.

Using nagels

In the corners of the structure, to increase the quality of the connection, an addition is used in the form of reinforcement by pins, they are called nagels. They are installed inside the bars, thereby reducing the mechanical load and eliminating the likelihood of deformation changes during drying. In the role of nagel can act as an armature or pipe made of metal, wooden variants are also used.

The joining of the bar to each other on the spikes is most often hardened by nails. For such a joint, a hole is cut in a plumb direction with a diameter slightly larger than the hardening size. The pin is inserted into the hole.

The size of the nagel in the range from 20 to 50 mm is chosen. The necessity of joining two rows determines the required length.

Bonding

Often when building a house there is a need for increasing the length, this problem can be solved by various methods of longitudinal fastening. The most widely spread docking method with root longitudinal spikes and alignment with the name "half tree", they do not lag behind and bond with a skew lock. When creating angles, the first two variants do not differ from similar methods, except for the consecutive arrangement of the beams themselves.

Longitudinal bonding using nagel (vpolderova) is a qualitative and simple method. The implementation of the process is quite convenient. Horizontally placed joint bars and drilled a few holes with a drill. Insert in the hole round pins of wood with a diameter of up to 25 mm. For the processing of the docking site, glue can be used. Wood arbor with further gluing is also used for fastening with root spikes.

Complexity in the implementation of the connection is distinguished by an oblique lock. A bevel is produced at the end, while on one wooden element a groove is formed, and on the other - a spike.

Warm Angled Connection

When joining the beams, it is worth paying attention to the insulation of the joints. Due to inaccuracies in the grooves, non-sealed joints in the bonding points, the thermal protection is reduced. To avoid this, you can use a warm angle. To create it, a heat insulator in the form of flax fibers or pakli is placed in the junctions between the beams. This should be done during the installation of a warm corner.

There are many methods that allow you to make corners of walls, to join the beam 150х150 during its build-up. The main factor that determines the quality of all works is the correct installation. The choice of the required method depends on the type of construction and operating conditions.
