ABSTRACT:
A coupling particularly for use with colliery roadway supports. The coupling between an upright channel section or `I` beam and a crown beam of a similar cross-section is formed from two plates. At least a first of the plates is formed so as to lie between opposed flanges of the upright and opposed other of the two plates. The first plate extends beyond the head of the upright to a lip portion hooking all its width over the lower flange of the crown beam with preferably a bolt passing through the lip portion, the crown beam and opposed other plate. The clamping of the two plates together by the bolt or bolts securing the upright to the crown beam achieves a high resistance to lateral loading on the assembled beams to form a support.
