<p>An arrangement for erecting wall and/or ceiling structures has a support profile (10), on whose cross-sectionally approximately T-shaped webs (11) at least one load-bearing means (13) for wall and/or ceiling parts is releasably fastened, and also has a tension lock (turnbuckle) (14) which is releasably fastened within the hollow load-bearing member (13) and exhibits a central retaining element (17) and two lateral retaining elements (15, 16), arranged symmetrically with respect to the latter, consisting of spring steel. The retaining elements (15, 16, 17) engage into adjacent, undercut grooves (12) formed by the webs (11) and are braced with respect to two adjacent webs (11) of the support profile (10) by a transversely directed tensioning device (28) which passes through the three retaining elements (15, 16, 17) in mutually aligned cutouts (25, 26, 27) and can be actuated by turning. At the same time, the tension lock (14) is fixed within the load-bearing member (13) by the tensioning device (28). The two lateral, resilient retaining elements (15, 16) are connected to one another in one piece at their rear ends (at 18), remote from the support profile (10), and are arranged in a tension-lock housing (21) which also receives the central retaining element (17) and the rotatable tensioning device (28). The tensioning device (28) exhibits a central, cylindrical part (29), which passes through the three retaining elements (15, 16, 17) in mutually aligned bores (25, 26, 27), and two outer disc parts (30, 31) which are located at the ends of said cylindrical part and enclose the two lateral retaining elements (15, 16) between them and the inner surfaces (32, 33) of which butt against in each case one of the two lateral retaining elements (15, 16). The inner surfaces (32, 33) of the two outer disc parts (30, 31) each have an actuating bevel corresponding to the plane which is formed by the associated lateral retaining element (15 and 16, respectively). <IMAGE></p> |
