CONSTRUCTION PROFILES FOR ROOM LINING WITH HINGED PLATES Russian patent published in 2009 - IPC E04F13/08 

FIELD: construction.

SUBSTANCE: construction profile system for room lining with hinged plates consists of the parallel load-bearing profiles of H-shape cross section. Each profile is formed by two poles and connecting bridges. One of the poles is attached to the load-bearing structure, preferably, to the wall or floor slab. It is hollow in cross section and represented as open box with openings at the basis, which are pre-drilled or drilled during installation and intended for screwing to load-bearing structure. Fastening bracket is also placed in the open box so that it can move in lengthwise direction and fix screw connection head. The opposite wall of the box is formed by side wall bends directed towards each other and adjoining bridges, which are preferably parallel to each other and installed with a clearance. At the same time, free ends of bridges are bent to the opposite sides and parallel or tilted to the basis forming the lengthwise gap in the second pole bearing structure from the spacer profiles. Each spacer profile is made with open hollow directed to hinge plates and formed by the pole and two shelves. In addition, longitudinal axes of load-bearing and spacing profiles are perpendicular, whereas spacing profile ends are placed between load-bearing profile poles from mounting profile represented with extruded profile in the form of band with two pairs of longitudinal fins with longitudinal projections. The above projections of one longitudinal fin pair being on the front side of the band are brought into the grooves of the adjacent hinge plates. The grooves are widened at their depth. In cross section, spacing profile shelves ends are mated with pole and bent outwards to the pole ends and parallel to it, while free ends are bent twice, i.e. initially, outwards and inwards the spacing profile. As a result, folded projections are formed in bending points and located outside spacing profile. The construction profile system is provided with additional spacing profiles with longitudinal axes being parallel to load-bearing profile axes. Additional spacing profiles are linked with the main spacing profiles by means of connecting bracket represented with rectangular chute having vertical walls. In addition, the connecting bracket can move lengthwise and crosswise with regard to spacing profiles. There is a rectangular hollow made in the bracket basis along the central axis and a clearance meeting spacing profile band configuration in the middle of the vertical walls. Two pairs of longitudinal slots are made at both sides of clearance opposite to each other. The slots are bent inward of connecting bracket and distanced from the basis by the thickness of folded projection of the spacing profile. The connecting bracket basis is made ribbed in the gap between vertical walls. Dowels directed inwards are located in the centre of ribs and at the end of connecting bracket. The mounting profile band is made hollow and its cross section is represented with two trapezium connected by their short sides. This band is brought into the open hollow of spacing profile, while longitudinal projections of the second longitudinal ribs pair are located from the side walls of the mounting profile band and symmetrical to each other. They are implemented as hook-shaped bend directed to the rear side of the hollow band. The folded projections of the spacing profile are located in hook-shaped bends of the mounting profile.

EFFECT: improvement of profile and hinge plates fastening reliability, reduction of mounting works labour effort and exclusion of tensioning forces in points of adjacent plate connection and possibility of hinge plates adjusting with regard to each other.
