摘要:
The invention essentially relates to a modular block (1) forming a permanent formwork element for the construction of a portion of a swimming pool, particularly the stairs, comprising: a side board (5) provided with a tab (7) extending along a longitudinal side (2.1) of the main surface (2); and a hollow space (8) located on the opposite side of the side board (5) with respect to the main surface, such that a side board (5) of another modular block can engage with the interior of the hollow space by means of nesting. The block (1) also preferably comprises hooks (15) and male (12) and female (13) attachment means for facilitating the assembly thereof to other adjacent modular blocks (1) of the staircase.
