System for connecting square hollow profiles end-to-end comprises connectors with cooperating surfaces which are held together by transverse shear bolt locked in place by two pins

摘要

The system for connecting square hollow profiles (1, 2) end-to-end comprises connectors (8, 9) with cooperating surfaces, bores, ribs, forks, pre-centering zones and wedges and pockets (37, 38). A transverse shear bolt (19) passes through bores in the center of each connector, holding them together. This is locked in place by two pins. Sloping bolts (15, 16) secure the connection.
