The proposed utility model relates to the woodworking industry, in particular, to the creation of building timber in the form of glued beams made of components, which can be used in the construction of individual private house-building, as well as in any building structural solutions of one and two-story buildings. The author was faced with the task of creating a timber structure that would provide: - an increase in its size in height and width; - the speed of assembly of the constructed wooden structure; - light weight of the beam itself; - thermal conductivity of the assembled wooden structure; - cheaper manufacturing of wooden beams. As a result of solving the task, the following technical effect was obtained: - an increase in the size of the beam in width and height is ensured by the fact that the parts of the supporting frames are glued from dry lumber of the required height and width. The proposed design of the beam allows you to produce a bar with a height and width of 40 cm .; - the speed of assembly of wooden structures using the proposed timber structure is due to the fact that the beam of a given size is made exclusively in production, up to painting or varnishing in any color, in connection with which the assembly time of buildings under construction is limited to a minimum; - the light weight of the beam itself (almost 2 times) is due to the fact that the proposed structure has voids, due to which a lightweight foundation is used in the construction of structures, which ultimately reduces the cost of the wooden structure being built; - thermal conductivity (which is important for our northern regions) of the assembled wooden structure is ensured due to the fact that some heat-insulating material can be laid in the existing voids in the timber structure, which also affects the reduction in the cost of constructed wooden structures; - with modern production of timber, expensive German equipment is required, and in the production of the proposed design of high timber, hand tools are enough, and this does not affect labor productivity. The high beam consists of 2 side panels and 2 load-bearing frames used in corner joints.

To connect the beam to each other in the side panels, a groove is milled from above, a spike from below. The load-bearing frames consist of wooden panels 4 cm wide. Their number in the load-bearing timber frames depends on the requirements for thermal conductivity. The minimum width of the supporting frames is 15 cm, the maximum is 40 cm.

Description

The proposed utility model relates to the woodworking industry, in particular, to the creation of building timber in the form of glued beams made of components, which can be used in the construction of individual private house-building, as well as in any building structural solutions of one and two-story buildings.

A utility model is known that is a prototype of the claimed solution, “Bar” (Patent No. 23406, Russia, IPC В27М 3/00, CJSC “VIRA” LTD, Kralin V.S., Kralin I.V., Kochnev A.I., Levinsky Yu.B., Baranov D.V., No.2002100850 / 20, declared 08.01.2002, publ. BIPM No. 17, 06.20.2002. Rus.), Containing the same elements connected in a packet with the largest plane area, whose internal elements have a length shorter than the external elements forming one or more intermediate spaces, the internal elements being connected to the external elements of the double-sided nail plate mud. The disadvantage of the prototype is that this bar cannot be built in a reliable structure, it can only be used as load-bearing elements of floors between floors.

The author was faced with the task of creating a timber structure, which would provide:

- an increase in its size in height and width;

- the speed of assembly of the constructed wooden structure;

- light weight of the beam itself;

- thermal conductivity of the assembled wooden structure;

- cheaper manufacturing of wooden beams.

As a result of solving the problem, the following technical effect was obtained:

- an increase in the size of the beam in width and height is ensured by the fact that the parts of the supporting frames are glued from dry lumber of the required height and width. Instead of the timber used today, a height of 20-22 cm and a width of 20-25 cm. The proposed construction of the beam allows the production of a beam up to 40 cm high and up to 40 cm wide, which is essential for wooden structures of the northern climatic zone;

- the speed of assembly of wooden structures using the proposed timber structure is due to the fact that the beam of a given size is made exclusively in production, up to painting or varnishing in any color, in connection with which the assembly time of buildings under construction is limited to a minimum;

- the light weight of the beam itself (almost 2 times) is due to the fact that the proposed structure has voids, due to which a lightweight foundation is used in the construction of structures, which ultimately reduces the cost of the wooden structure being built;

- thermal conductivity (which is important for our northern regions) of the assembled wooden structure is ensured due to the fact that some heat-insulating material can be laid in the existing voids in the timber structure, which also affects the reduction in the cost of constructed wooden structures;

- with modern production of timber, expensive German equipment is required, and in the production of the proposed design of high timber, hand tools are enough, and this does not affect labor productivity.

The high beam consists (Fig. 1) of 2 side panels 1 and 2 of the supporting frames 2 used in corner joints. Their number in the beam depends on the length of the beam and on the project of the house: at least 2 pieces, maximum - 4 pieces. The side panels and the supporting frames have technological grooves 5, 6, 7. To connect the beam to each other (Fig. 1), a groove 3 is milled on the side panels and a spike 4 from the bottom. The supporting frames consist of wooden panels 8, 9 4 cm wide . Their number in the supporting frames depends on the requirements for thermal conductivity. The minimum width of the supporting frame is 15 cm, the maximum is 40 cm. (Obtaining such dimensions of a wooden beam is impossible according to the currently existing technologies). If for more than 2 meters, supporting frames are not required, then for fastening the panels to each other, it is necessary to install (Fig. 2) a wooden mortgage 10, and its size depends on the size of the manufactured high beam. In the existing voids 11 (FIG. 2), any heat-insulating material 12 is laid. FIG. 3 shows a sample of the assembly of a house being constructed using a high beam.

Assembling a high beam is as follows. The parts of the supporting frames are glued from dry lumber of the required height and width. After that, technological slots for angular connection are cut out in the side panels and the supporting frames. Then the supporting frames are placed on a special rack. By glueing 4 workpieces (2 panels and 2 load-bearing frames), the beam is clamped in a collar.

Using the proposed high-beam structure in the construction of any wooden one and two-story buildings will significantly reduce the time of their construction, reduce the cost of construction. For example, the production of the required amount of timber for the construction of a one-story house measuring 9 × 9 m. Takes only 3 days.
