摘要

The panel has an interior wall (2) and an exterior wall (3) connected by a spacer wall. The interior wall has longitudinal assembling edges for assembling a male hook element and a complementary female hook element. The edges are equipped with reinforcement units for reinforcing a flexural strength of a L-shaped inner locking branch (10), where the reinforcement units comprise a bar (28) parallely extending to a perpendicular end flange (11) and cooperating with a heel rest (30) on a inner surface of the exterior wall of the panel.
