SYSTEM OF MAKING INSULATED CONCRETE WALLS AND CONNECTION STRAPS ON HINGES Russian patent published in 2009 - IPC E04B2/86 

FIELD: construction.

SUBSTANCE: present invention pertains to building components for constructing concrete walls, and more specifically, to connection straps, which are used for holding panels at a distance and parallel each other. The connection strap for joining the first and second wall panels, where the first and second wall panels lie parallel each other, have first and second end pieces. Each of the end pieces stretches between the first edge, which is inside the wall panels, and the second edge. The second edge has a first hinged member. The first end piece is in the first wall panel. The second end piece is in the second wall panel and the centre section, stretching between the pair of second hinged members. The centre section lies between the first hinged member of the first end piece and the first hinged member of the second end piece, in which one of the first and second hinged members is in form a hinge pin, and the other has at least one first gudgeon and at least one second gudgeon. The hinge pin forms a vertical hinge axis. The first finger is vertically displaced from the second finger. The first and second gudgeons can support opposite sides of the hinge pin. Description is also given of the building component part.

EFFECT: easier moulding of end sections using injection moulding process, reduced number of stages, required in the injection moulding process, as well as cost of making connection straps.
