Abstract (en)
[origin: EP0317695A1] In a metal scaffolding for buildings, in particular a tubular scaffolding, the elements (1, 2) of which are connected to couplings (4, 9), the halves (4, 9) of which, each fixed to one element (1, 2), becoming interlocking and each being braced by a wedge mechanism (8), one flank (32, 53) of the driving wedge (12) being assigned to an inclined face (7) of one coupling half (4) and the opposite flank (13) being designed as a wedge face, the driving wedge (12) extending in a gap (11) which is opened in the other coupling half, it is provided according to the invention either that the driving wedge (12) slides on one flank (32) assigned to the coupling inclined face (7) on a metal lamella (24) which is fixed in the gap (11) of the other coupling half (9) and reaches through an opening (19) up to the inclined face (7) of the coupling half, or that the wedge-taper faces (40, 41) of the driving wedge (12) are formed on both sides of the driving wedge (12) and their face planes meet inside the driving wedge (12) behind the wedge flank (13), the gap (11) exhibiting a wedge groove (43), on the flanks (44, 45) of which the friction faces for the wedge-taper faces (40, 41) of the driving wedge (12) are formed. <IMAGE>
