Nonslip strip for substrate security on steep steel roofs uses projecting pins off strip to clamp into plate holes with spaced pins on alternating sides of strip.

摘要

A pin (10) projecting from the wall (9) of the security strip plugs into one of the bearer plate (1) holes (3) to be held clamped in the hole. The pin can be bonded into the hole (3) and the strip wall (9) once plugged into the plate (1) stands at right angles to the plate surface (2) and the pins project in parallel from the raster of holes in the wall (9). The pins should conform to hole shape and the wall (9) can be zee-shaped or repeatedly angled. The holes (3) can be formed from cell walls (4) and so dictate the course of the strip (8) walls. The pin (10) spacing can exceed that of the wall holes and the strip should be as long as the plate itself (1).
