CONNECTION UNIT FOR ELEMENTS OF PREFABRICATED/COLLAPSIBLE FRAME OF VOLUMETRIC STRUCTURE AND PREFABRICATED/COLLAPSIBLE FRAME OF VOLUMETRIC STRUCTURE Russian patent published in 2023 - IPC E04B1/58 E04B1/26 

FIELD: construction.

SUBSTANCE: group of inventions relates to a prefabricated frame of structures and a connection unit for its elements. The collapsible frame includes at least two adjacent contours of longitudinally fastened together elements with mating protrusions and depressions cut out in the end parts, outside of which there are holes in which protrusions of transversely located connecting elements are installed, having stops in the end parts and projections with holes for fixing wedges. In this case, the protrusions of the transverse connecting elements connecting adjacent contours are installed in the holes of the connected elements and are rigidly fixed by fixing wedges installed in the holes on the protrusions of the connecting elements with the ends of the wedges overlapping the mating edges of the protrusions and depressions of the connected elements.

EFFECT: increased strength of the frame.
