Brief description of the installation without cutting of the corners and without the passage of the cover plates profiled.

摘要

The invention relates to a method for laying shaped plates, in particular corrugated ones, without cutting the corners and without drilling, which plates have a thickness E /= 4 mm and are intended for the roofing of buildings. It involves, next to the transverse overlapping between two plates 1' - 1'', the combined use of at least: - a hook 4 intended to simultaneously hold the top end of the lower plate 1' on the purling 2 and to position and retain the bottom end of the upper plate 1''. - an expansible cylinder 11 placed transversely along the top end of the lower plate 1', preferably semi-lapped, and providing, by means of friction, the resistance to the lifting forces as a result of the depression exerted on the roofing.
