The floor unit (21) has a trough including edges that permit to rest the unit on beams (24, 25). The unit (21) rests on a support (23a) of a vertical wall (23), as the distance separating base of the unit (21) and edges is equal to thickness of heel of the beam situated under corresponding edge, to firmly support several floor units. The trough`s inner space is partitioned by an inner partition (8) having two walls (9, 10). |
