Abstract (en)
[origin: FR2790496A1] The invention concerns a trapdoor comprising a rectangular frame (1) and rectangular slabs (2, 3), the frame (1) being equipped with holding wedges (121, 123) and the slabs are provided with fixing fingers (201, 202, 301, 302) capable of co-operating with the holding wedges to make the slabs integral with the frame. The invention is characterised in that the holding wedges (121, 123) are made integral with the rabbet (12) edge, spaced apart from the rabbet base (11) and the plane (P) of the recess, each slab comprising, at its inner surface (22, 32), respective web plates (23, 24, 33, 34) parallel to the length (L) of the frame and perpendicular to the plane (P) of the recess, and each web plate is run through by a perforation receiving, transversely relative to the web plate, one of the fixing fingers.
