Load-bearing member for a floor or similar surface

摘要

A load-bearing member for a propped-up floor or similar surface, in particular for a false floor in a switching-substation building and for bearing installations, such as switchgear cabinets, installed therein, having a profile which exhibits a receiving space which is flanked by side walls and is intended for anchor elements of uprights or the like, is intended to be improved in that arranged on at least one side wall (20) of the profile is at least one upwardly open hook profile (40, 42) running in the longitudinal direction, and a counter-member (48) of a load-bearing extension (50) which bears lockably against the profile engages into the channel opening (46) of said hook profile. Preferably, a pair of hook profiles (40, 42) which is spaced apart from one another on a side wall (20) are provided for a pair of counter-members (48) of the load-bearing extension (50), said pair of counter-members engaging in the opposite direction. Running between said load-bearing extension and profile, in a channel (64) formed by the two, is a locking bar (66) which locks the two. <IMAGE>
