The utility model relates to the field of construction and can be used for flooring, the coating of which consists of individual rigid blocks of small linear dimensions (up to 0.6 m), mainly parquet, in residential and public buildings.

Currently, various nodes docking (connection) of parquet blocks.

Known docking groove-crest. This technical solution consists in the fact that a groove is made at one end of each of the connected blocks, a ridge (protrusion) at the other end; when laying, the crest of one of the connected blocks is inserted into the groove of the other block, see, for example, RF patent No. 2108432 for cl. E04F 15/02 of 03/21/96; RF application Go98103 869/03 for class. E04F 15/02 of 03/11/98.

Known for the docking of floor blocks, for example, parquet boards, including pazypropyls made at the ends of the connected blocks, into which the connecting elements are inserted - dowels, see Grigoryev MA, Handbook of a young carpenter and carpenter, M.,

Forest industry, 1984, p. 40; Alikin B.K., Parquet floors, M., Adelant, 2000, p. 207 (copy attached).

The disadvantage of the above technical solutions is the difficulty of ensuring an even horizontal floor surface, as well as the dependence of the quality of the floor surface on the differences in thickness; other blocks and the unevenness of the base.

The closest in technical essence to the claimed utility model is the docking unit of floor blocks, primarily parquet blocks, having front, bottom and end surfaces, including grooves in the nodes of their docking, made on one of the surfaces of the blocks, and connecting elements installed in the grooves. Before laying on the edges of each block on its front surface, flat recesses are performed, and when laying blocks on their front surface, grooves are formed by combining the recesses; insert strips are glued into the formed grooves, see Alikin B.K., Parquet floors, M., Adelant, 2000, p. 207-208 (copy attached).

This technical solution is taken as a prototype of this utility model.

Known technical solution has the following disadvantages:

the difficulty of ensuring a flat, without ledges, horizontal floor surface; obtaining a quality surface

flooring is possible only with the use of individual blocks calibrated by thickness and on a fairly even base;

-the difficulty of ensuring a smooth, without steps, floor surface is also due to the fact that the large length of the joint and the need to install a long insert in the groove forces a recess to be made larger than the thickness; the insert is different, which eliminates the possibility of installing it without a gap;

- Insufficient rigidity, joint strength caused by a combination of thick joints in joints; ita (this is necessary to ensure the strength of the flooring) and a narrow insert significantly smaller in thickness than the shield.

These shortcomings result in poor quality parquet coatings; parquet coatings inevitably require long-term finishing work (scouring, grinding, etc.).

The present utility model is based on the solution of the problem of creating such a unit for joining floor blocks that would ensure a smooth horizontal surface of the floor covering, regardless of differences in the thickness of the blocks, unevenness of the base and its deviation from the horizontal surface. In addition, the problem of increasing the rigidity of the floor during bending and eliminating the violation of its integrity in the assembly.

According to a utility model, this problem is solved due to the fact that in the docking unit of floor units having front, bottom and end surfaces, including recesses made in floor units and connecting elements installed in these recesses, these recesses are made in the corners of each unit on its lower surface and have a flat bottom, the surface of which is parallel to the front surface of the block, while the distance between these surfaces is the same for all blocks; connecting elements can be made stackable in height; however, in adjacent end surfaces of the floor blocks, grooves may be made in which the keys are installed; these grooves in the end surfaces of the floor blocks can be made in the form of segmented cuts, and the keys are made in the form of plates.

The applicant has not identified sources containing information about technical solutions identical to this utility model, which allows us to conclude that it meets the novelty criterion.

The usefulness of the utility model is illustrated by drawings, which depict:

in FIG. 1 - a separate floor parquet block, bottom view;

figure 2 is a fragment of the floor covering of three floor parquet blocks, a perspective view;

in Fig.3 - a separate floor parquet block with inserted dowels, top view.

In the corners of each floor parquet block 1, recesses 3 with a flat bottom 4 are made on its lower surface 2, the surface of which is parallel to the front surface 5 of block 1. The recesses of 3 adjacent blocks form single grooves 6 in which the connecting elements 7 are installed, abutting against the bottom 4 recesses 3, and from the bottom into the base 8 of the floor. The recesses 3 are in the form of sectors with an angle of 90, and the connecting elements 7 are made in the form of disks with a circular cross section. In adjacent end surfaces 9 of the blocks 1 between the recesses 3 there are made segment-shaped grooves 10 in the form of cuts, in which the keys 11 are placed, made in the form of plates of plywood 4 mm thick.

The distance between surfaces 4 and 5 is the same for all blocks 1. Blocks 1 are laid on the floor base 8 with the face surface 5 facing up, connecting adjacent blocks 1 to each other. When laying adjacent blocks 1 on their lower surface 2 form single grooves 6 of circular cross section, combining the recesses 3 on the lower surface of 2 blocks 1; the upper surface of all the formed grooves 6 is at the same distance from the front surface 5 of the blocks 1, due to the fact that the bottom 4 of all the recesses 3

5 is made equally spaced from the front surface 5 of all blocks 1. This allows to obtain a flat, without steps, floor surface when using different thicknesses of individual blocks.

In the grooves 6 formed on the lower surface of the 2 blocks 1, connecting elements 7 are installed, which abut against the bottom 4 of the recesses 3 and from the bottom into the base 8 of the floor. The height of each connecting element 7 is selected individually, taking into account the irregularities of the base 8 and its deviation from the horizontal surface at the docking nodes. This allows you to get a flat and horizontal surface of the floor, regardless of the roughness of the base 8 and its deviation from the horizontal surface.

In a specific example, the connecting elements 7 are made stackable in height, in particular, in the form of a set of discs glued together, which greatly simplifies the process of selecting the height of the connecting elements 7.

Thus, the floor covering created from the docked floor blocks 1 turns out to be, as it were, laid at the docking nodes on peculiar supports from sets of discs resting against the bottom

the base of the 8th floor and compensating irregularities of the latter and its deviation from the horizontal surface. This significantly reduces the requirements for processing the base 8 of the floor.

The technical result achieved is enhanced due to the fact that in the adjacent end surfaces 9 of the blocks 1 between the recesses 3 there are made segment-shaped grooves 10 in which the dowels 11 are placed. Thus, the floor covering is a single strong elastic plate, which not only improves the evenness and horizontalness coating, but also increases its rigidity during bending, i.e. increases the strength of the coating.

The strength of the coating can also be increased due to the fact that the segmented grooves 10 can be mated with the keys 11 without a gap; in this case, keys 11 are used, the shape and dimensions of which correspond to the shape and dimensions of the grooves-cuts 10. All joints can be hardened with glue.

To improve the anti-vibration properties of the floor covering, the cavity formed between the lower surface of 2 blocks 1 and the base 8 of the floor can be filled with mastic, adhesive with filler, applied with the aid of a comb spatula, or foam, etc.

For the implementation of the utility model used conventional, well-known materials and devices, which determines the compliance of the utility model with the criterion of industrial applicability.
