Description

The utility model relates to the field of construction, namely to the design of the corner joints used in the field of wooden housing construction.

A known design of the corner connection of heat-insulating wooden beams (RF patent No. 2531128, 10.20.2014), containing external, central and internal walls, between which partitions and insulation are located, while partitions connecting the central and external walls are located between partitions, connecting the central and internal walls.

This design is complex and time-consuming to implement, can be applicable for large-scale wooden buildings. It should also be noted that the specified angular connection has a significant thickness, as a result of which the moisture content of the wood of the external and internal walls during operation starts to differ, which leads to uneven shrinkage of the external contour formed by the external walls and the internal contour formed by the internal walls, also to vertical movement these circuits and, as a consequence, the appearance of longitudinal gaps, reduce the ability to retain heat, reduce the service life and reliability of the structure.

высоты внутренней стенки и имеющий скошенную поверхность.The known design of the angular connection of the prefabricated wall element (RF patent No. 19693, 09/27/2001), adopted as the closest analogue to the claimed solution, containing external and internal walls, between which there are partitions in grooves of the "dovetail" type, with external the walls of the corner joint intersect with the shoulders, the inner walls of the corner joint intersect and abut the through grooves made on the outer walls of the corner joint, and at the intersection of the inner walls a groove equal to

the height of the inner wall and having a beveled surface.

высоты внутренней стены, приводит к неравномерной усадке и кручению стен относительно продольной оси, что в случае сильного ветра и/или разницы температур внутри и снаружи здания способствует его продуву и недостаточному сохранению тепла. К тому же искривление стен приводит к появлению трещин и высыпанию наполнителя, что снижает срок службы и надежность конструкции.This design is difficult to implement, as it has a large number of grooves of various types, including grooves with a beveled surface, which increases the complexity of manufacturing design documentation for the house, significantly increases the cost and time of its construction. The presence of a groove equal to

the height of the inner wall, leads to uneven shrinkage and torsion of the walls relative to the longitudinal axis, which in the case of strong wind and / or temperature differences inside and outside the building contributes to its blowing and insufficient heat storage. In addition, the curvature of the walls leads to cracks and spilling of the filler, which reduces the service life and reliability of the structure.

The objective of the utility model is to create a simple and energy-saving design of the corner joints, reducing the complexity of its manufacture.

The technical result of the utility model is to increase the reliability of the design of the corner joints by eliminating the deformation of the external and internal contour of the building and ensuring free movement of the external and internal contour of the walls relative to each other during shrinkage and during operation of the building.

The technical result is achieved by using the angular connection “double beam - dovetail”, containing the external circuit formed by the external walls, the internal circuit formed by the internal walls, the insulation located between the external and internal circuits, while the external walls have grooves with additional longitudinal grooves, located on the side of the inner and outer surfaces of the outer wall, the outer contour is attached “to the bowl”, the inner wall at the junction with the outer wall has a “fins” connection chkin tail. "

Performing an external contour with fastening the external walls “in the bowl” in the presence of grooves and additional longitudinal grooves from the side of the internal and external surface of the external wall allows you to tightly lay the beams on each other without creating gaps between them, direct the wind flow along the external contour, and not inside the building , as was the case with the closest analogue, thereby eliminating the possibility of torsion of the external walls and blowing of the building, which increases the energy consumption and reliability of the building structure. In addition, the execution of the external contour with the external walls fastened “into the bowl”, the dovetail connection at the junctions of the internal wall with the external wall allows the external and internal walls to move freely in the vertical direction without horizontal movement, which prevents the formation of cracks and helps to improve the reliability of the building during operation.

In FIG. 1 shows a top view of the angular connection “double beam - dovetail”, in FIG. 2 is a top view of the corner connection “double beam - dovetail” with the intersection of the inner walls with the outer walls, in FIG. 3a is a general view of the outer wall with a groove and longitudinal grooves, in FIG. 3b is a side view of the outer wall with a groove and longitudinal grooves, in FIG. 4 - connection of external walls to an external circuit.

The corner connection "double beam - dovetail" contains the outer walls 1, inner walls 2, insulation 3 located between them, while the outer walls 1 have grooves 4 with additional longitudinal grooves 5 located on the side of the inner and outer surfaces of the outer wall 1. In this case, the inner wall 2 at the junction with the outer wall 1 has a dovetail connection 6 (Fig. 1)

In FIG. 1, the inner contour formed by the inner walls 2 has a T-shaped profile. In this case, one inner wall 2 has a dovetail joint 6 with the outer wall 1. In this case, the junction of the inner walls with each other also has a dovetail joint 6.

In FIG. 2, the inner contour formed by the inner walls 2 is attached “to the bowl”. In this case, both inner walls 2 have a dovetail connection 6 with the outer walls 1.

As the basis for the external and internal circuits, a profiled beam of forced chamber drying is used, while the thickness of the beam is 45-90 mm, the height is 120-190 mm, while the moisture content of the beam can vary in the range of 10-22%. Also, glued beams can be used as material for the external and internal contours.

As a heater, located between the external and internal walls, ecowool, vermiculite, isocork and other materials having a loose structure can be used. The insulation is either filled up or blown under pressure into the space between the internal and external circuits during or after assembly of the entire structure of the corner joint. The thickness of the insulation, as well as the thickness of the wall timber, can be different, and depends on the purpose of the construction object and the climatic conditions of a particular region.

In the bars acting as external walls 1 and intended for the formation of the external contour, grooves 4 are made with additional longitudinal grooves 5 located on the side of the inner and outer surface of the external wall 1. Additional longitudinal grooves 5 are located diagonally relative to each other. The grooves 4 are recesses that are performed on the upper and lower sides of the timber in a standard manner (Fig. 3a, 3b). Further, the external walls 1 are assembled into an external circuit (Fig. 4).

The fastening of the inner contour formed by the inner walls 2 is as follows:

1) at the end of one of the walls (external 1 or internal 2) a trapezoidal spike (“dad”) can be cut, and a trapezoidal groove (“mum”) at the end of an adjacent wall. Then these walls are joined by means of the dovetail connection;

2) a trapezoidal groove ("father") can be cut out on both adjacent walls (external 1 and internal 2) and connect them using the Hoffman plastic dowel W3-W4 (for example, http://www.desin.ru/techs/press_690_197.htm ) Next, make the adjacent walls dock with a durable dovetail joint.

The indicated wall connection options can be used to obtain a T-shaped inner contour (Fig. 1), a cross-shaped inner contour (Fig. 2).

To ensure uniform shrinkage of the external 1 and internal 2 walls of the structure along the entire height of the walls, in the corners and in length in increments of 1.5-2.5 meters, threaded rods with a diameter of 8-12 mm are placed in pre-prepared holes. The rods from one end are fixed rigidly, and at the other end, through the washer, the nuts are tightened. As the walls shrink, the nuts tighten.

The inventive design uses two well-known joining beams that do not require high complexity, which allows to increase the pace of construction. The elimination of cracks allows you to get a reliable and energy-saving design, which is also its advantage.

Thus, the claimed design allows to increase the life of the constructed building, increase its reliability, maintain heat and provide comfortable living conditions.
