Abstract (en)
[origin: US4843780A] A construction plate is provided consisting of two outer plates folded to form webs extending laterally therefrom so that the webs form spacers between the outer plates, and with end supports terminating the face sides of the outer plates arranged perpendicular to the ducts of the folds. Each outer plate has a corrugation having an M-shaped cross section adapted to hold the front edge of a web of an opposing outer plate, the corrugation being displaced with respect to the webs by half a division and extending parallel to the webs.
