Beam for a grid in a suspended ceiling |
摘要 |
<p>A compression relief section (40) in a beam (23) in a grid (22) for a suspended ceiling (20) that permits controlled collapse of the section during a fire, whereby the ceiling (20) is kept relatively intact. The section (40) has a channel (42) formed from the web portion (27) of the beam (23), and a crushed bulb (26) with a hump (55), along with a flange (31), that fold from compression forces, while resisting such forces. There is no interference between the folding portions and the ceiling panels when the section collapses. <IMAGE></p> |
