Construction material sheet for industrial type cupboard, has hermaphrodite coupling edge band with coupling reliefs, which are placed in symmetrical positions with respect to symmetry plane, where plane is mid-span of coupling band

摘要

The sheet (9) has a vertical rear lateral fold (6) limiting a panel (1) with respect to another panel (2) that has a hermaphrodite coupling edge band (3) opposite to the fold. The coupling band is provided with a set of pair of complementary male coupling reliefs (20) and female coupling reliefs (30), where the reliefs are placed in symmetrical positions with respect to a symmetry plane which is mid-span of the coupling band for permitting an assembly by top-down coupling of a pair of sheets (9, 9A) made of an elastically deformable construction material.
