PURLIN BEAM COMPRISING ATTACHABLE ENDS

摘要

The invention relates to a beam comprising ends that can be attached to one another, such that one of the ends is equipped with front projections for guiding the vertical movement of the other end which is equipped with guides having a shape that matches that of the projections. In addition, one of the ends comprises lower projecting arms for supporting the other end once the latter is in place, thereby defining a single contact zone that enables the supported end to be detached during disassembly by rotating same on the contact zone.
