Description

(54) KNOT OF WALL FLOORING

The invention relates to the construction of buildings for various purposes, as well. to the device of floors with a covering from rolled or slab materials like linoleum, PVC of tiles, fiber boards, etc.

The knot of joining the floor to the wall is well-known, including a linoleum coating glued on a cold mastic on a fine-grained layer. porous concrete Cl.

The closest to the invention technical solution is the floor assembly, which includes a coating of rolled or plate materials on the adhesive layer, the base of the floor above the heat and sound insulation layer and the fastening details of the floor element 2.

The disadvantages of the known structures of the floor assemblies are the increased concentration of toxic components released by adhesive structures, the high humidity of the base of the floor and the heat and sound insulation layer, which leads to a deterioration of the strength and sanitary-hygienic qualities of the floor.

These drawbacks are caused by the absence of an underground floor space that allows for effective ventilation of the floor, close adjoining of its horizontal layers to the underlying layers over the entire floor area, similar to adjoining the floor to walls (partitions), and the presence of vertical and horizontal diaphragms - materials with NCD-CIM vapor permeability coefficient , including layers of glue KN-2 and 3, Pussies, etc.

Due to slow drying

10 concrete and. floor elements made of wood or wood-based materials (battens of reinforcing cages of gypsum-concrete panels of the base of the floor, soft insulating fibreboards)

15, the strength and durability (biostability) of the floor structure is reduced, the turnaround time is reduced, which leads to unreasonably high reduced costs.

20

The consumption of sound insulating materials and adhesives for attaching the coating is also high.

The invention is the improvement of sanitary and hygienic qualities.

25 by reducing the toxic emissions of glue, increasing the strength and durability of the floor, reducing the cost of flooring.

This goal is achieved by the fact that the node

30 adjoining the floor to the wall, including

the coating of rolled or tile materials on the adhesive layer, the base of the floor is monolithic or assembled, the heat and sound insulating vertical and horizontal layers and plinth are provided with supporting parts for fixing the coating placed at intervals along the walls, the height of the supporting part being equal to the sum of the thicknesses of the base of the floor and at least two adhesive layers, and the adhesive layer is not brought to the edge of the base of the floor at a distance of 4-6 thicknesses of the latter, the vertical heat and sound insulation layer is located between the support part and the monolithic a floor base, vertical layer is disposed between the wall and the support part

FIG. 1 is a floor plan of FIG. 2 is a diagram of the movement of air in the peripheral zone of the floor; in fig. 3 - constructive option & abutment of the floor unit to the wall with a monolithic base; in fig. 4 - the same, with precast base.

The design of the floor adjoining unit to the wall contains a system of support parts 1 under the edges of the covering 2 and hollow sections 3 and 4 adjacent to the floor layers.

Supporting parts made of a material of low rigidity, for example, of wood, are buried or installed on the surface of the heat and sound insulation layer 5 made of filled, slab, etc. materials. These parts also serve as partitions between the sections 3 as hollow compartments along the lateral face of the base 6.

The base of the floor is monolithic lightweight concrete, prefabricated concrete panel, wood-based panels or similar materials. When arranging floors by a monolithic lightweight concrete tie near the supporting parts, a continuous layer of sound-proof material of minimal thickness is installed, to which the tie is adjacent (Fig. 3).

Parts 1 can also separate hollow compartments from adjacent ones filled with sound insulating material to provide sound insulation if this material is provided by the project (conventionally not shown).

Along the contour of the cross section of the sections 4, the air layer is bounded by the base surface b by the adhesive layer 7 of the coating 8 and the supporting details 1.

By placing the top of these parts 1 at the level of the top of the adhesive layer 7 and the presence of glue-and-fastening of the edges of the coating 2 to the support parts 1 using the tension of the coating from its shrinkage, an expansion of the air gap from 1 to 2 thicknesses of the adhesive layer is created. Wherein

the cross-section of the hollow sections 4 gets a trapezoidal shape with a difference in the levels of the floor surface within the allowable limits.

The arrangement of the hollow portions 4 through 5 of the periphery of the room, i.e. in the area of furniture arrangement, and their total area, is 1 / 3-1 / 4 of the floor area, due to the requirements of preventing the formation of waves, swelling of the Q layer of the interlayer-coating (for example, linoleum) from the horizontal component of the load-walk in such operational effects .

FIG. 2, the dotted line indicates the direction of movement of air containing the toxic gas phase of the adhesive composition, and air with a relative humidity of the adhesive layer 7, base B, and heat and sound insulation

20 of the material 5 into the ambient atmosphere through the system of hollow portions 3 and 4. This uses a gap between the edges of the cover 2 and the wall 9, as well as the known hole arrangements

25 and the cracks in the plinths.

In order to provide sound insulation for prefabricated bases between the support, the part and the wall (partition)

 insert a thin layer of soundproof material, such as trimming

PVC, heat and sound insulating linoleum, soft fiberboard and the like (Fig. 3).

The implementation of the invention allows to satisfy the sanitary and hygiene requirements: the floor requirements, timely reduce the floor humidity in terms of strength, biostability of its wooden parts and wood layers.

slabs, prefabricated gypsum concrete base panels, as well as reduce the consumption of sound insulation materials and glue under the floor covering. This will provide an opportunity to save on cost.

floor about 1.2 rubles. on 1 square. m
