(57) An improved panel consisting of a plate (2) with its four edges bent at 90°, the
edges h.aving their ends (8, 8') cut to a determined shape, wherein:
the end (8) is cut to form:
- a lower rectangular appendix (12) of dimensions I x h,
- an upper rectangular appendix (14) of dimensions c x b,
- an L-shaped segment (16) of dimensions z x s,
- a segment joining the end Q of the L-shaped segment (16) to the upper end of the
appendix 12 and having a height "a" such that h+a+z+b corresponds to the height H
of the bent edge (6),
this segment assuming different shapes depending on the angles α and β which the segment
forms respectively with the vertical passing through the point P of the appendix (12)
and with the horizontal passing through the point
Q of the L-shaped segment (16),
the end (8') presenting:
- a lower rectangular appendix (18) of dimensions n x h,
- a second upper appendix (20) of dimensions b x c, and
- a segment (22), joining the point R to the point S, which is of height t = a+z .
