Group of inventions relates to the field of construction, in particular to systems beam profiles for the production of screed thickness from 15 mm to 40 mm clean floors or other structures or facilities, such as flat roofs.

The closest analogue to the claimed invention is a system of beam profiles for concreting in which each beam includes a longitudinal supporting member, United with him two perforated side of stalky its base is connected with tightening element (EN 19069 U1, class E 04 3/293, 2001).

A disadvantage of the known designs is the lack of adhesion of the profile beams with fill material.

An object of the invention is to eliminate this drawback and, in addition, reducing the complexity of the manufacturing system by eliminating the tightening element due to increase bonding of the beam profile with fill materials, as well as increasing its stiffness.

This problem is solved due to the fact that the system beam profiles for concreting contains at least two profiled beams, each of which includes a longitudinal supporting member with grooves, United with him two perforated side walls with the waste from them in the opposite side of the perforated bases, the free edges of which are bent symmetrically to each other in the direction of the supporting surface of the reasons to form an obtuse angle, and the profile beams are connected in line by at least one longitudinal guide insert, having a convex cross-section worktop and located in the recesses of the longitudinal load-bearing elements adjacent longitudinal beams.

The problem is solved also by the fact that the system p is Alky, each of which has a longitudinal supporting member with a cavity, United with him two perforated side walls with the waste from them in the opposite side of the perforated bases, the free edges of which are bent symmetrically to each other in the direction of the supporting surface of the reasons to form an obtuse angle, and the profile beams are connected in line by at least one lifting strap having a convex cross-section worktop and installed with their longitudinal recess on the guide inserts placed in the recesses of the longitudinal load-bearing elements adjacent beam profiles.

The problem is solved also by the fact that the system profile beams for carrying out concrete work on the third version contains at least two profiled beams, each of which includes a longitudinal supporting member with the protrusion, United with him two perforated side walls with the waste from them in the opposite side of the perforated bases, the free edges of which are bent symmetrically to each other in the direction of the supporting surface of the reasons to form an obtuse angle, and the profile beams are connected in line by at least one lifting strap,a separate estimate of the adjacent beam profiles.

For all variants preferably, the free edge of the grounds had been bent to form the angle 135.

The system may be further provided with adjusting screws mounted in the holes in the bases.

To improve occupancy rates beams concrete portion of the holes of perforated side walls and the reason it is advisable to position on the fold line of the side wall of the base, so that one part of the area of each hole was located on the side wall and the other on the base, preferably the bend line side wall of the base is passed through the centers of these holes.

These holes may be round, or oval, or other shape.

Profile of the beam and formed from the profile beams are made as follows.

Profile beam 1 is intended for the production of screeds, mainly finishing floors with a very small thickness of the screed 2 (25 mm) with a guaranteed occupancy rate of the internal cavity of the profile beams casting a mixture of 3 regardless of its viscosity and factionalism fillers (Fig.1).

Profile beam 1 (Fig.2) contains two perforated side walls 4 extending from them to the opposite side of the perforated bases 5. The free edges of the bases are bent downward toward the support surface with the formation of an angle more than 90 degrees. The optimal size of the bend 6 is 135 degrees.

The bends 6 provide education additional internal cavity under beam height h even in the absence of adjustment screws, which are filled with concrete or other filling mixture, ensuring increased the scene.

Two symmetric bend 6 at an angle of 135 degrees to increase the rigidity of the beams

The beam is provided with adjusting screws 7 (Fig.3) inserted into the holes of the base 5 of the beam, to provide adjustment of the required level of the beam, and the angle of inclination of the sexes.

Profile beam is produced from a flat piece of steel 8 (Fig.4) roll forming mills to ensure strict symmetry of the cross-sectional beam profile and straightness in the longitudinal direction.

Pre-perforation steel billet provides the location of two symmetric groups of holes of the adjusting screws 9 and the valve 10, the latter are arranged in such a way that passes through the centers of the bend line “side wall-base” (Fig.5).

The location of the holes 10 facilitates and accelerates the filling of the internal cavity of the profile beams with concrete or other filling mixture due to the location of the one part, preferably half of the holes 10 on the side surface of the beam 4, and the second part is based on the 5 beams.

Holes 10 can be round or oval or any other configuration.

The proposed beam profile can have a different shape of the longitudinal bearing element of the first embodiment, the longitudinal supporting member 17 is made with a longitudinal recess 12 (Fig.5). In this case, the beam profile with longitudinal guide box 11, is placed in the recess 12 beams having different cross-sectional shape, for example the shape of a truncated vertical plane or not truncated “swallow's tail” (Fig.6A, b). The same form have the top and bottom of the insert 11.

The upper leveling the working surface of the guide insert 11 has a convex surface directed outwards beam profile.

The lateral surface of the guide insert can be curved or one curved and the other flat.

Plastic rails insert 11 with a length L equal to the length of the beam, inserted into the recess 12 of the beam shift and=15-10 mm, which allows you to easily construct a system by coupling two adjacent beams in line with the plastic guide, which also fulfills the function of a connecting element (Fig.7, 8).

The protruding portion 13 of the plastic guide insert 11 one profiled beams with light force (or by using a mallet) is inserted into the recess adjacent profiled beams, forming a system of special beams for carrying out concrete work on the first version of the runtime.

In another embodiment, the profile beam 1 can be subjeuy on protruding from the recess 12 of the beam portion of the plastic guide inserts 11 and forming its upper surface levelling the surface of the beam.

Beam with plastic lifting strap 14 makes it easy to vary the thickness of the poured screed in the direction of increasing the value of the height used lifting straps 14.

Lifting strap 14 of length L is placed on the plastic guide box 11 of the same length with the shift of 15-20 mm, which makes it easy to put two adjacent profiled beams in a line, forming a system of special beams for carrying out concrete work on the second version of the run (Fig.10, 11).

At the bottom of a plastic lifting strap 14 is formed a groove 15 having in cross section the shape of a truncated vertical plane or not truncated “swallow's tail” (Fig.9).

In the third embodiment, the beam profile as a levelling surface can be used longitudinal surface of the projection 16 of the beam profile, is placed in the zone of intersection of the side walls 4 of the beam. The cross section of the projection 16 of the beam profile can take the form of “swallow's tail” (Fig.12).

To vary the thickness of filled screeds in this case can also be used lifting strap, similar to the lifting rod 14 mounted his groove on the ledge 16 (similar to Fig.10).

System profile beams by the third variant in this case the lifting bars with shift.
