The plates are connected with plastic ties supplied with eyelets for fastening them to the plates, with each other and with Staromonetny blocks. Plates contain cage nuts installed in their manufacture in quantity, depending on the number of couplers used in the same block, in which are screwed the mounting hooks, concatenate with one of the lugs of the screed and enabling smooth adjustment of the verticality of installation plates by changing the depth of screwing hooks into the cage nuts with different thickness of the wall mounting hooks of different sizes, as well as by sequential coupling of several plastic ties bolted connections (see RF patent №2342502, publ. 27.12.2008).

The disadvantages of the known device is its complex design, involving time-consuming laying of insulation during construction works.

In addition, from the "prior art" is known device described in German patent document No. 20007312 U1, publ. 31.08.2000 and includes two reinforced concrete slabs between which is a layer of insulation. Two concrete slabs bonded reinforcing ties in the form of spatial reinforcement.

The disadvantages of the known device is its complicated structure.

The present invention is to eliminate the above disadvantages.

The technical result consists in the ease of use of the present device is TBA at the time of construction works, due to the absence of complex operations during construction or tiling, and in the absence of transmission temperature inside concrete structures, excluding local freezing and formation of dew point on the steel reinforcement inside the concrete.

The technical result is ensured by the fact that the retained formwork contains two opposed spaced plates, the outside of the insulation and the inner concrete, bonded to each other and forming between them a space to fill flowable material capable of solidification. Internal slab of concrete made of reinforced and contains reinforcing elements of two types. While the reinforcing elements of the first type is made V-shaped in cross-section of the bent mesh, installed in parallel and at equal distance from each other and provide accommodation at the same distance from each other and secured in parallel relation thereto reinforcing elements of the second type representing the spatial reinforcing elements consisting of three longitudinal rods and two studs, curved V-neck zigzag. When this curved rods simultaneously connected vertices to one longitudinal rod, and the other vertices to the other two rods with the formation of armoires prismatic eskay form. In addition, the reinforcing elements of the first type is made protruding from the concrete slab, and provides for the joining and fixing thereto the outer plate made of insulation and punctured fiberglass rods with clamps, ensure the connection and fastening to the rear surface plate of the heater grid, made with the possibility of joining reinforcing elements of the first type.

In accordance with particular cases run, the device may have the following features.

The insulation is rigid.

Insulation made of foamed polystyrene.

The essence of the present invention is illustrated by the following illustrations:

figure 1 shows this device in longitudinal section;

figure 2 is a side view of the concrete slab;

figure 3 is a top view of the plate of insulation;

4 is an isometric image of a reinforcing element of the first type;

figure 5 - image of a reinforcing element of the second type.

The illustrations shows the following structural elements:

1 - concrete slab;

2 - slab insulation;

3 - reinforcing elements of the first type;

4 - reinforcing elements of the second type;

5 - mesh;

6 - rods with clamps;

7 - metal rod.

Permanent formwork contains two opposed spaced plates, one of the which is made of concrete 1, and the second plate 2 is made of rigid insulation (foamed polystyrene). Concrete slab 1 is performed with embedded reinforcing elements 3 and 4 and has a thickness of 55-70 mm Reinforcing elements of the first type 3 set with equal step, they are V-shaped in cross section. They are made by a method of bending of the road grid 3×50×50, or from a road grid other range. The reinforcing elements of the first type 3 provide accommodation at the same distance from each other and secured in parallel relation thereto reinforcing elements of the second type 4. In addition, the reinforcing elements of the first type 3 are exposed from the concrete slab 1, and provides for the joining and fixing thereto the outer plate of the heater 2.

The reinforcing elements of the second type 4 represent spatial reinforcing elements armoires prismatic shapes, which consist of three longitudinal rods and two studs, curved V-neck zigzag. When this curved rods simultaneously connected vertices to one longitudinal rod, and the other vertices to the other two terminals.

This type of reinforcement ensures a concrete slab 1 stability during transport, the movement of the crane, as well as during pouring of the core.

Plate of the heater 2 with equal increments of glass punctured the plastic rods 6, equipped with a spacer element on one end and an anchoring element for fixing at the other end. Fiberglass rods 6 topped with retainers in the form of spacer washers, ensure the connection and fastening to the rear surface plate of the heater 2 grid 5. The implementation of the rods 6 of fiberglass to prevent the transmission of temperature inside the concrete structure, eliminates local freezing and the formation of dew point on the steel reinforcement 3,4 inside the concrete. In such a constructive implementation of the valve retains its load-bearing properties and slowly corrode.

5 mesh provides a connection plate of the heater 2 to the slab of concrete 1 and their mutual fixation. This is accomplished by locking the triangular peaks (peaks protrude from the concrete slab reinforcing elements of the first type 3, which are passed through the grid cell 5 with mesh side 5 facing the concrete slab 1, while on the other side of the grid 5 through the triangular peaks of the missing metal rods 7. 5 mesh is a welded mesh, formed of wires arranged in two mutually perpendicular directions and welded at the intersection (the square shape of the cells).

The present device is used as follows.

Before concreting on site to a concrete slab 1 join the complementary plate of the heater 2, contains mounted on its rear concatenate the side of the road grid 5, fixed to the plate 2 by means of rods with clamps 6. Mutual fixation plates 1, 2 is provided with locking the triangular peaks of the reinforcing elements of the first type 3, the peaks of which protrude from the concrete slab 1. The exposed tops of the reinforcing elements of the first type 3 pass through the grid cell 5 with mesh side 5 facing the concrete slab 1. While on the other side of the grid 5 through the triangular peaks of the reinforcing elements 3 miss metal rods 7. In such a constructive implementation of the reinforcing elements of the first type 3 hold the plates 1, 2 between them, and fronting the arching effect of concrete during concreting of the core.

Prior to concrete placement, concrete slab 1 perform the openings in the perimeter which impose additional praemegaceros formwork (for example: wooden Board).

The implementation of the plates 1 and 2 fastened allows the construction to concrete core designed for pouring opening formed by the two plates 1 and 2, set horokanai for electricity. The casing containing the plate of the heater 2, reduces the time of construction, because it does not require additional installation of insulation on the outer wall. In addition, n is the difference of the insulation protects the structure from low temperature impact - in the case of heating the concrete in the production of works in the winter.

Next, carry out concreting core, including layer-by-layer stacking and vibrating of concrete.

During the construction of the building smooth concrete plate 1 facing into the room, this wall requires minimal finishing. Plate 2 from the heater turned out that in contrast to the known technology reduces manufacturing time of work and effort when installing insulation on the outer wall.
