Patent attributes
The end of a transversely extending beam is joined to a wall structure by a self-releasing structural assembly. It has a first portion anchored to the wall. A second, fireproof and non-thermally degradable portion of the assembly sticks out from the wall. The assembly has a thermally degradable member mated to the second portion of the structural assembly. Both portions have slots for accepting beam fasteners. The beam fasteners squeeze the end of the beam, the support bracket seat, and the consumable, thermally degradable member in compression. When exposed to heat or flame the consumable, thermally degradable member softens, releasing the tension in the beam end fasteners, and releasing the compression in the structural sandwich of parts. The end of the beam is then able to translate away from the wall structure. The consumable member can be inspected without removing the beam end from the seat.
