Description

The utility model relates to the woodworking industry, in particular to elements of building structures, and is intended primarily for the construction of permanent load-bearing walls in low-rise construction.

Known wooden building block Kurochkin (utility model patent No. 124275, IPC E04B 1/10, publ. 20.01.2013). A wooden building block is made of several edged dried boards of equal caliber in length, width and thickness, connected to each other with the formation of grooves and ridges along the length and at the ends of the block due to the longitudinal and transverse displacement of the boards relative to each other and joining into a block using an adhesive composition .

The disadvantages of this technical solution is that, firstly, all parts (lamellas) are located horizontally, which accordingly shrinks (shrinks) after the structure is erected. Secondly, all parts (boards) are made of a longer material, which accordingly increases the cost of the block, and is also insufficient for good thermal insulation.

The closest in technical essence is the patent RU (11) 157715 (13) U1, Published: 12/10/2015, Bull. No. 34. A wooden building block made of edged dried boards of equal caliber in length, width and thickness, along which relief notches are made, assembled from a set of packages made up of vertically arranged boards of the same length, perceiving vertical loads, while the boards are interconnected in the longitudinal direction by the side planes, and the packages are connected to each other with the formation of grooves and spikes along the length and at the ends of the block due to the longitudinal and transverse displacement of the packages relative to each other, and the packages are interconnected using glue and / or other fasteners, while in the parts to be joined, holes are drilled for fasteners at a predetermined distance from each other in accordance with the diameter of these elements.

The disadvantages of this technical solution is that all parts (lamellas) are located from a set of packages made up of vertically arranged boards, which does not provide increased loads in vertical and horizontal planes.

The objective of the utility model is to create a wooden building block with improved soundproofing and heat-saving properties of the inner and surface layers, aimed at restraining the linear expansion of wood.

The technical result consists in improving the soundproofing and heat-saving characteristics of the surface and inner layers with a more preferable structure aimed at restraining the linear expansion of wood.

This is achieved by the fact that a wooden building block made of edged dried boards, assembled from a set of packages made up of cross-spaced vertical and horizontal boards with an unequal length and width arrangement of wood fibers and connected to each other, with the formation of grooves and spikes, along length and at the ends of the block due to the displacement of the packages relative to each other, while laser and/or milling porization is performed on the vertical and horizontal boards.

Laser and / or milling porization is made in the form of through slots and / or in the form of through holes, except for facade and internal finishing front boards.

The depth of the slots in the facade and interior and finishing faces is up to 75% of the thickness of the board. The width of the slots is 0.5-3.0 mm, depending on the linear expansion of the wood.

The proposed utility model is illustrated by drawings.

In FIG. 1 shows a wooden building block, general view.

Where 1 - vertically arranged lamellas; 2 - horizontally arranged lamellae; 3 - through ventilation holes, cavities, self-filling with resin - resin.

In FIG. 2, displacements of packages relative to each other, top view.

In FIG. 3-10 - types of porization.

In FIG. 3-6 to improve sound insulation.

In FIG. 7-10 to improve thermal insulation and compensate for the linear expansion of wood.

The proposed utility model is a wooden building block of a unified size, assembled from separate packages, consisting of cross-spaced vertical 1 and horizontal 2 boards of the same length (lamellae), which are glued and fastened together with a certain offset, resulting in the formation of locks with all sides to connect the blocks to each other. For gluing boards and packages using environmentally friendly glue.

This utility model provides for the creation of universal building elements that make it possible to erect walls carrying vertical structures, partitions of any shape, thickness and profile from sawmill and woodworking waste without the use of additional gluing, cementing and sealing materials and special fasteners, which reduces the cost and simplifies construction.

Given that the structure is made of cross-located vertical and horizontal boards, shrinkage of wooden structures is excluded, and the possibility of perceiving vertical and horizontal loads increases from 5-17 times.

For the manufacture of a load-bearing wooden building block, there is a large selection of types and varieties of wood, it can be pine, larch, spruce, birch, aspen, oak, etc., or combined, for example:

90% pine - 10% larch (for interior decoration);

70% pine - 30% cedar; 90% pine - 10% oak or mahogany veneer;

90% larch - 10% veneer.
