Description

This utility model relates to the design of panel floors with concrete and porcelain stoneware, namely for deformable foundations in modular block buildings.

The prior art modular floor (patent for invention RU2633840, publ. 10/18/2017 Bull. No. 29). The modular floor contains a fixed fixed frame attached to the wall, in which several boards are located. The upper surface of the fixed frame and individual boards are located in the same plane. Individual boards are divided into long boards and short boards. Long boards and short boards consist of frames and flat panels, while there is a gap between adjacent frames, a flat panel is attached to the top of the frame, flat panels adjacent to each other are in close contact with each other; the frame consists of a rectangular frame and legs. The disadvantages of this technical solution is the fragility of the design when used in block-modular buildings during transportation, and this solution also has a high complexity and manufacturing cost.

The known floor (patent for utility model RU 73898, publ. 06/10/2008 Bull. No. 16), including a horizontal base of retaining material placed on a concrete slab and trimmed on one horizontal plane, and placed on the obtained supports a rough coating of two layers of plywood with a finish coating laid on the top layer of plywood. The supporting material is made of pieces of beams obtained from cutting along one horizontal plane of wooden beams installed on a concrete slab and fixed to a concrete slab, while each sheet of plywood of the first layer is attached to all the indicated pieces of beams on which the sheet of plywood rests and the sheets of plywood of the second the top layer is overlapped with sheets of plywood of the first layer and attached to the last. This utility model uses combustible materials (wood), and also can not absorb the load from the deformation of the frame of a modular building block.

The disadvantages of this technical solution is the fragility of the design when used in block-modular buildings during transportation.

The closest to the claimed technical solution are raised floors PERFATEN (production of ASP-Technology http://www.al-sp.ru) (Product catalog “Raised floors PERFATEN atlant”, 2017). Raised floors consist of slabs and the supporting subsystem on which they are installed. The supporting subsystem consists of struts, a longitudinal power element between them. These racks are installed at the corners of the plates. A support is laid on the supporting system (mainly aluminum foil or steel), then a raised floor plate and a finish coating. The disadvantages of this technical solution is the fragility of the design when used in block-modular buildings during transportation.

The task to which the claimed utility model is directed is to develop a panel floor of a modular building that is resistant to destruction during transportation of the building.

This problem is solved due to the fact that the claimed technical solution contains a supporting frame attached to the walls, made in the form of a crate, on which the panels, adhesive and tiles are laid in series, and the panels and tiles are laid so that the seams between the panels and tiles coincide, however, between the panels and between the tiles, gaps of 3-5 mm are made, which are filled with elastic compounds. The panels are concrete and the tiles are made of porcelain stoneware. A polyurethane sealant is used as an elastic composition. The panels are attached to the frame using polyurethane mastic.

The technical result provided by the given set of features is the ability to absorb loads from the deformation of the frame of a block modular building, which in turn allows you to transport a block-modular building without destroying the tiled floor.

The panel floor is used for the installation of floors with concrete and porcelain stoneware cladding on deformable foundations in block-modular buildings.

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

Where

1 - frame frame modular building

2 - panel floor frame

3 - floor panel

4 - porcelain tile

5 - glue for porcelain tile

6 - elastic sealing composition

7 - insulation.

The panel floor of a block-modular building contains a supporting part attached to the walls — frame 1 — with a frame 2. There are two ways of attaching to the walls of a building: either rigidly fastening the floor frame through additional steel corners fixed to the floor frame along the perimeter, or a mobile structure when a gap is left between the floor frame and the wall, which is filled with polyurethane mastic.

The frame 2 is made in the form of a crate. Caracas 2 can be adjustable, made of stringers, support posts and PVC linings, assembled in a crate, or unregulated, made of a profile pipe welded in the form of a crate.

Panels 3, mainly concrete, are laid on the frame 2. Part of the panels 3 can be installed without fixing, for the possibility of their dismantling forming a "raised floor", if necessary, panels 3 to the frame 2 can be attached using polyurethane mastic.

On the panel 3, adhesive 5 is applied and the facing tile is laid 4. The seams (gaps) between the panels 3 and the tiles 4 are filled with elastic compounds 6 (polyurethane sealants).

The thickness of the adhesive for the installation of porcelain tiles is selected based on the technological instructions of the manufacturer of the adhesive, in the general range from 6-10 mm. Brands of adhesives used: Ceresit CM 17 Super Flex, Litokol SUPERFLEX K77, or adhesives similar in properties.

As an elastic composition, polyurethane sealants can be used, for example, Bostic PU 2639 (http://www.bafus.ru/100010332/char/), or other similar compositions having the following characteristics:

 - good adhesion to concrete, porcelain stoneware and metals;

- elongation at break of at least 250% at a load of about 0.5 MPa;

- Shore hardness of at least 45-55A;

- thermal stability in the range of at least: from -40 ° C to + 80 ° C;

- chemical resistance;

- water resistance.

The base of the floor panel is made of concrete slab and can be lined with ceramic granite tiles.

The bearing part of the panel floor is used in two types.

First type. The bearing part is made of a profile pipe (preferably 40x40x3 in size, manufactured according to GOST 30245-2003 or similar TU, from steel grades C235, C245 and C345 according to GOST 27772-88). Pipes of the frame are arranged with a pitch of 600 mm both in the longitudinal and in the transverse direction, forming a lattice structure with a cell 600x600mm (along the axes). In this case, the pipes to each other have a rigid connection in the form of a weld. Corrosion-resistant coating of this design is made by applying soil-enamels to the prepared surface of the frame, soil-enamels are selected depending on the requirements for the operation of the structure or other customer requirements.

The second type. The bearing part consists of construction stringers, support columns and PVC linings. Support racks are installed on the load-bearing elements of the building (floor) with a pitch of 600x600mm, and are fixed to glue or anchor. Further between the racks are installed stringer and secured with screws (screws). The structure assembled in this way also forms a lattice structure with a cell of 600x600mm (along the axes).

Floor panels are made by molding concrete in molds (preferred dimensions 600x600 mm) with reinforcing elements such as fiber and steel mesh. In this case, the molds can be made of plastic, polyurethane or metal, and the molding process can take place on a vibrating table. After molding, the products in the molds are installed in stacks with a height of no more than 3 rows. After that, the stacks are covered with a plastic film to prevent evaporation of moisture. The aging temperature should be at least 15 ° C. Additional heating is not required. After 24 hours of exposure in the molds, it is possible to carry out stripping (release of products from the molds). The products are stripped off on a special table with vibration, and to facilitate the stripping of the mold with the products, it is recommended to warm them up for 2-3 minutes in a bath with hot water (temperature 45-50 ° С). In this case, the effect of high thermal expansion of polymers compared to concrete is used. After stripping, the panels are stacked on Euro pallets, tying them with packing tape. To ensure further hardening of concrete and preservation of the presentation of products, they must be covered with polyethylene shrink or stretch film. In the summer, products are dispensed when they reach 70% of design strength, which approximately corresponds to 7 days of concrete hardening, counting from the moment of its manufacture. In winter, tempering is performed when 100% of the design strength is reached (28 days from the moment of concrete preparation).

The base of the floor can be insulated, based on the requirements of the thermal characteristics, due to the areas of operation and the purpose of the building.

The device is assembled as follows.

The frame is assembled in one of the above ways. After the frame is ready, floor panels are laid on it, so that the edges of the panel rest on the frame, installation is performed on polyurethane mastics. Tile is attached to the panel with glue, while it is important to lay the tile so that the seams between the floor panels and the tiles coincide. A gap of 3-5 mm is left between the floor panels and between the tiles, which after installation is filled with polyurethane sealant or a material similar in characteristics. This gap is necessary both for gluing tiles and panels together, and for the floor to deform in a plane, without destruction. This method of laying provides the necessary deformability of the base.

Transportation of the building is carried out by any available transport (water, road, rail, air), depending on the logistical availability, while there are no special requirements for the transportation of a modular building in terms of floors.
