The invention relates to the production of building work in the winter, mainly in the new monolithic frame construction, where the self-supporting wall is being built in one floor between the lower and upper monolithic reinforced concrete beams with simultaneous thermal insulation on the basis of self-leveling concrete and architectural cladding.

Known methods of thermal insulation framing walls in low-rise construction (frame used galvanized profile or wooden timber treated with preservative) non-autoclaved monolithic foam concrete and cladding enclosing structures outside facing bricks, plates DSPS (cement Board) and SCP (chip-cement), leaves ACL (asbestos-cement), drywall (gypsum) and plasterboard (drywall), followed by the application of plastering and painting. A prerequisite is the availability of the ventilation holes due to the low permeability of the used coating materials. Phased inner lining is also plates DSPS, ACL, drywall, plasterboard filled the inside of the exterior walls of a monolithic non-autoclave foam concrete density of 200-250 kg/m3[1].

Also there is a method of thermal insulation and the facing surface of the walls the tiles, where the details of the mounting of tiles mounted on the reinforcing behold the ke, fixed on the wall surface, and the insulation is carried out by filling the space between the surfaces of walls and tiles, insulating material, such as liquid foam, with ventilation channels do by means of a rigid plastic tubes slide them up as curing insulating foam [2].

The main drawback of these methods is hypothermia concrete mixture is filled in a space between the thin plates of the outer and inner lining, while construction work in the winter because they will not provided the normal temperature hardening of the concrete, which entails a reduction of strength properties and increased shrinkage deformation of the insulating foam.

The closest to the invention, the technical solution is the way of insulation and the facing surfaces of walls tiles by laying and fixing details of the mounting fixed to one end of the reinforcing mesh, mounted on the wall, and then filling the resulting space between the surfaces of walls and tiles plastic insulating foam concrete mixture and the formation of foam concrete vertical ventilation ducts, where the tiles with ptogressive design ends, is made of p is nabetani mixture composition, wt.%: Portland 20-70, aluminous cement 5-7, fume 2-4, the foaming agent is 0.1 to 0.25, the pigment 2,9-3,75, filler 15-70, record details of the mounting is made in the form of brackets, due to clogging of the free end of the bracket and into the upper slot end concrete tiles, and each tile is hermetically connected by drawing on grooving the surface of the ends of the layer of cement-latex adhesive thickness 1-2 mm greater than the allowable tolerance in the dimensions of the tiles [3].

The technical solution of the invention [3] in a simplified form is as follows: outer thin-wall tile in a well-known solution [2] is replaced with tiles from foam with an average density of 800 kg/m3with ptogressive design ends that in its thermal performance is more insulated, with increased frost resistance and decorative concrete tiles is achieved by using the proposed optimal composition of the concrete mix, and increased the tightness of their stacking is accomplished by applying a cement-latex glue.

The disadvantages of these methods are, first, a relatively large volume of monolithic insulating foam to ensure the required level of thermal protection of buildings in very cold climates, for example, for gakudo, cf is the ranking, with the volume of traditional insulating materials (for example, mineral wool and expanded polystyrene foam slabs) and, secondly, there is provided the normal temperature hardening of concrete during construction works in winter, which reduces the quality of monolithic foam concrete.

The objective of the invention is the provision of additional insulation wall surface in very cold climates and ensure optimal heat and humidity curing the concrete mix and quality monolithic insulating foam concrete in construction work in the winter.

The problem is solved in that in the method of thermal insulation and the facing surface of the walls the tiles with ptogressive design surface ends, made of foam concrete mix, by stacking and fixing the details of the mounting is made in the form of brackets, one end of which is fixed behind the steel mesh installed on the wall and the free end scored in the upper slotted end of each tile, and each tile is hermetically coupled deposited on the grooved surface of their ends by a layer of cement-latex adhesive thickness, the greater of 1 -2 mm, the variation of the size of the tile, and then filling the resulting space between the surfaces walls and tiles plastic insulating foam concrete mixture with education is the W in the concrete of specified mix of ventilation channels, additionally suit insulation polystyrene tiles that are attached to the tiles with ptogressive design ends fiberglass rods, one end of which is secured at the junction of the tiles with ptogressive design ends, the other end of which is connected to the inner layer of the wall, and the tile with ptogressive design ends are made of foam concrete mix composition in wt.%: Portland 20-70, aluminous cement 3-4, microclimate 8-10, the foaming agent is 0.1 to 0.25, the pigment 2,9-3,75, quartz sand 15-70, insulating foam concrete mixture using the following composition in wt.%:

Portland70-90
gypsum5-7
ground burnt rock5-23
the foaming agent PB-200, over and above

and vents are placed at an angle to the horizontal with access to technological holes.

The drawing shows a diagram of a thermal insulation wall (1) polystyrene tiles (2), connected between themselves and with ptogressive foam square is DAMI (3) through a flexible fiberglass rods(4), a layer of insulating foam concrete mix (5), the air channel (6), the moving plastic pipe (7)which defines the shape and angle of the ventilation channel output through technological hole (8).

The proposed method in the monolithic frame construction, where the self-supporting wall is being built in one floor between the lower and upper monolithic reinforced concrete beams, carried out in the following sequence: clutch of foamed concrete foamed concrete tiles on the adhesive base is in one floor between the lower and upper concrete overlay, then on the surface of the erected outer layer of the wall is arranged additional insulation of polystyrene foam boards, which allows to provide heat for the building and to create a positive temperature even in the coldest periods of winter and thereby significantly reduce the construction period, thus providing not only additional insulation of walls, but normal the heat and humidity regime of hardening the insulating foam. Next make the clutch inner layer of the wall of conventional concrete blocks or arrange the inner lining of the tiles, such as drywall or plasterboard, metal profiles, sequentially connecting them flexible fiberglass rods with one end closed is destroyed in the joints tongue and groove concrete tiles and pass through the polystyrene tiles. Used fiberglass rods conform to the Technical conditions of the Valves. TO-001-2099454-98. Novosibirsk. Through certain intervals along the height and width of the wall is satisfied with apertures through which the space between the surfaces of polystyrene plates and the inner layer of the wall gradually from the inside fill insulation foam concrete mixture. Ventilation channels formed by means of a rigid plastic pipes, which are set at an angle to the horizontal in the bottom layer mixes with access to technological holes, which removes excess moisture from insulation foam in the process of hardening.

Examples of the composition of the concrete mix for the manufacture of tiles with ptogressive design ends are shown in table 1.

In all the examples volaterrae ratio is 0.35. As foaming agents are widely known clearifly, LMS-1 and other Quartz sand can be used both natural and artificial origin. As the pigment used, the oxides of chromium, iron, cobalt, etc.

thermal conductivity of the tiles obtained from the mixtures according to the above examples, a thickness of 0.1 m is 0.18 to 0.20 W/mK.

The choice of insulation fast setting concrete mix is due to the fact that, even with a sufficiently high thermal resistance of the outer layers (cladding material concrete tiles 0.1 m + polystyrene tiles 0.1 m) in 2,74 m2In the coldest period is not possible to provide a normal temperature curing concrete mixture is filled in the space between the surfaces of polystyrene tiles and the inner layer of the wall, warmed only by individual premises unfinished building improvised means, for example using an electric heat gun. Therefore, in the context of the construction site when artificially created low positive temperature internal air space, which does not exceed +5C, high-quality monolithic insulating foam can be obtained only by the use of fast-curing composite binding, in which the duration of the curing does not exceed 30 minutes. In addition, in this case, to create conditions of "thermos" for the curing of concrete,taken in the winter concreting, in the outer cladding layer is arranged an additional thermal insulation of expanded polystyrene tiles.

Examples of insulating foam concrete mix are shown in table 2. Volaterrae attitude in the examples is 0.5.
