Fire-resistant demountable partition structure

摘要

A fire rated, demountable partition structure is disclosed which provides H-shaped studs having a core of combustion-resistant insulation material and opposed channel-shaped metal members secured to opposite faces thereof. Spline clips secure one side of the stud to the panel at joints therebetween. Each clip includes a lateral projection extending with a close fit into a kerf in the edge of the panel and a reverse bend providing opposed clip walls which fit along opposite sides of an adjacent flange on the stud. If the partition is exposed to a fire or the like, which tends to cause shrinkage of the panels and opening of the joints, the core of the stud bridges the joint and prevents direct exposure of the metal channel elements of the stud to heat or water through the opened joint. The spline clips are free to expand if the clips are subjected to greater heat than the channel members so that the stud is not caused to bow toward the fire side of the partition.
