20130205689 | CONNECTOR FOR SUSPENDED METAL CEILING FRAMEWORK AND CEILING EMPLOYING SAME - A connector for a ceiling framework including profile sections crossing one another at right angles for connecting the profile sections by being fitted to ends of certain profile sections which fit into apertures pierced in other profile sections. The connector includes two parts, a primary clip and a secondary clip, the two parts being associated with one another via a meltable mechanism capable of melting at a temperature of a fire to separate the two parts. In a fire, the secondary clips become detached allowing the primary clips to fit more deeply into the apertures of the profile sections, making it possible to absorb expansions due to heat of the fire and keep the framework and the ceiling sections it supports in place. The connector can be applied to the field of building construction, for example. | 08-15-2013 |
