Fire resistant partition wall panels - are erected on vert. grid allowing warping and expansion without collapsing

摘要

It is easy to assemble and comprises lower rail (1) resting on the ground, upper rail fixed to the ceiling, framework made of vertical members (3) spanning between rails and cross-pieces supported by vertical members. Lower panels (5) and upper panels are attached to the frame. The lower rail (1) has fixed section (7) with base attached to the ground and two vertical flanges (7b) and a second U-shaped section with base (8a) and two hooked flanges, each one folding back on itself over the vertical leg (7b) and ending in a hook (8d). When subjected to intense heat, the panels may expand but they remain fixed to the frame and upper and lower rails.
