COMPRESSION RELIEF SECTION |
摘要 |
A compression relief section in a beam in a grid for a suspended ceiling that permits controlled collapse of the section during a fire, whereby the ceiling is kept relatively intact. The section has a channel formed from the web portion of the beam, and a crushed bulb with a hump, along with a flange, 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.
