Detachable joint for ceiling grid construction - fits between intersecting channel sections with locking lugs and openings above section bottoms

摘要

The detachable joint is between two intersecting metal channel-sections, one of which has a recess extending from the bottom and the other one from the top. The width of the recesses matches the width of the channel-sections and their angle of intersection, and one of them has integral lugs protruding inwards and snapping into openings in the walls adjacent to the other. The lugs (6) in the channel-section (1) with the bottom reces (3) are above the bottom of the latter, while the openings for them in the other section are between the recess in it and the bottom.
