摘要

The artificial element has a parallelepiped frame (1) comprising a lower parallelepiped zone (2) and an upper parallelpiped zone (4) of same length. The lower zone comprising corner legs (3) and upper zone comprising a lower central rectangular projection (6) and an upper rectangular recess (5). are offset linearly to define complementary tongue and groove couplers for in-line mounting.
