Description

The invention relates to the field of construction and is intended for the device of underfloor heating of erected buildings and structures.

Known heated floor, arranged on the ground, containing installed on the ground reinforced concrete coating with air ducts made in it, laid on top of the reinforced concrete coating thermal insulation, on top of which there are elements for finishing the floor. (Copyright certificate SU No. 874932, IPC E04F 15/02, 1980)

The disadvantage of this design of the floor, arranged on the ground, is the use of specially made panels with channels, which leads to higher cost of the structure, as well as inefficient use of heat.

Closest to the claimed design of the floor, arranged on the ground, is a heated floor containing a reinforced concrete base installed on the ground, a waterproofing material laid on the reinforced concrete base, on which heat insulation in the unloaded state and a metal mesh are successively laid, while tubular heating elements are laid on top of the metal mesh they are zigzag and attached to it, and a reinforced screed is made on top of the insulation and the metal mesh, on which they are laid the elements of floor decoration (Magazine "Modern floors. Overview of technical capabilities and materials" No. 1, 2001, p.201, 202, 210, 211, Fig. 11.11) (1).

This technical solution is taken as a prototype of the proposed floor structure, arranged on the ground.

The disadvantage of this floor design is the inefficient use of heat.

The technical result of the claimed floor design is to increase the efficiency of heat use, as well as the use of simple, well-known materials, thereby reducing the cost of installing a heated floor.

The specified technical result is achieved by the fact that the heated floor, containing a reinforced concrete base installed on the ground, a waterproofing material laid on the reinforced concrete base, and heat insulation, a metal mesh, tubular heating elements arranged in a zigzag shape and attached to a metal mesh, reinforced screed and floor trim elements, are successively laid that it is equipped with a layer of sand 25-30 mm thick, poured onto a waterproofing material, and foam concrete installed on top of the sand GOVERNMENTAL blocks arranged with gaps relative to each other, filled with sand, and the density of insulation laid on the foam concrete blocks, 50-200 kg / m ³ and a thickness of not more than 50 mm in the unloaded state, plate made solution of coarse sand thickness determined by the formula a≥3b, where a is the thickness of the screed, b is the diameter of the pipes of the heating elements.

The proposed floor design is illustrated in the drawing, which shows a heated floor, arranged on the ground.

The heated floor, arranged directly on the ground 1, contains a layer of crushed stone 2, on which a reinforced concrete base 3 is installed, over which a waterproofing 4 is laid, made in the form of two layers of roofing material. A sand layer 5 with a thickness of 25-30 mm is poured onto the roofing material and foam concrete blocks 6 are installed with gaps relative to each other. The gaps between the blocks 6 are filled with sand 7, which is a filler and a sealant. Thermal insulation 8 in the form of mats or soft Bazaltin slabs with a density of 50-200 kg / m ³ and a thickness of not more than 50 mm in an unloaded condition is laid on the blocks. On top of the thermal insulation 8, there is a metal mesh 9 to which tubular heating elements 10, arranged in a zigzag manner, are attached using a metal wire (not shown). Elements 10 are made of metal. A screed 11 reinforced with a grid 12 is made on top of the heat insulation 8 and the mesh 9. The thickness of the screed is calculated by the formula a≥3b, where a is the thickness of the screed, b is the diameter of the pipe. The floor trim elements are attached to the screed.

Example 1

A layer 2 of crushed stone 100 mm thick is poured onto the soil 1 purified from the plant layer, onto which a reinforced concrete coating 3 with a thickness of 80 mm is installed, covered on top with two layers of waterproofing material 4 - roofing felt. A layer of sand 5 with a thickness of 30 mm is poured onto the roofing material, onto which standard wall foam concrete blocks 6 are installed with a size of 100 × 300 × 600 mm with 25 mm gaps from each other. The gaps 7 between the blocks are covered with sand, which is a leveling and sealing layer. On blocks 6 thermal insulation 8 is laid in the form of Bazaltin mats, durable, not reacting with cement mortar, with a density of 50 kg / m ³ and a thickness of 50 mm in an unloaded condition. A mesh 9 made of wire with a diameter of 1.0 mm and with cells of 50 × 50 mm was laid on thermal insulation. To the grid 9, tubular heating elements 10 with a diameter of 12.5 mm of metal plastic, which are arranged in a zigzag manner, are attached using a wire with a diameter of 1.5 mm. A screed with a thickness of 40 mm (screed thickness is determined by the formula a≥3b and due to the properties of concrete expand when heated) is made of a solution of coarse sand reinforced with a metal mesh of wire with a diameter of 4 mm with cells 150 × 150 mm. The floor finish includes a leveling layer 13 with a thickness of 10 mm, 14 adhesive for tiles with a layer of 10 mm and 15 ceramic tiles with a thickness of 20 mm.

To the grid 9, tubular heating elements 10 with a diameter of 12.5 mm of metal plastic, which are arranged in a zigzag manner, are attached using a wire with a diameter of 1.5 mm. A screed with a thickness of 40 mm (screed thickness is determined by the formula a≥3b and due to the properties of concrete expand when heated) is made of a solution of coarse sand reinforced with a metal mesh of wire with a diameter of 4 mm with cells 150 × 150 mm.

A layer 2 of crushed stone 100 mm thick is poured onto the soil 1 purified from the plant layer, onto which a reinforced concrete coating 3 with a thickness of 80 mm is installed, covered on top with two layers of waterproofing material 4 - roofing felt. A layer of sand 5 with a thickness of 30 mm is poured onto the roofing material, onto which standard wall foam concrete blocks 6 are installed with a size of 100 × 300 × 600 mm with 25 mm gaps from each other. The gaps 7 between the blocks are covered with sand, which is a leveling and sealing layer.

A screed with a thickness of 40 mm (screed thickness is determined by the formula a≥3b and due to the properties of concrete expand when heated) is made of a solution of coarse sand reinforced with a metal mesh of wire with a diameter of 4 mm with cells 150 × 150 mm. The floor finish includes a leveling layer 13 with a thickness of 10 mm, 14 adhesive for tiles with a layer of 10 mm and 15 ceramic tiles with a thickness of 20 mm.

To heat the floor, the coolant - water or other non-freezing liquids - is supplied to the tubular heating elements associated with the heat source. Thanks to the proposed solution, heat is evenly distributed under the heated area, heating the floor to a predetermined temperature. A solution of coarse sand (sand is a filler) includes cement, water, lime. The use of accessible and widespread materials makes the proposed design materially accessible during the construction of various buildings and structures.
