摘要

Unit (1) for the construction of slab foundations, the unit (1) presenting a number of modules (M) of domes (C) which are made of plastic material and which are suitable for being laid in the ground of a site in accordance with modules (M) of at least one dome (C) which are arranged laterally in relation to each other in order to form a gridwork of channels (2) which are engaged by reinforcing bars or sheaths (F); and a number of interconnecting elements (10) which are arranged in an intermediate position between at least two adjacent modules (M) of domes (C) in order to connect to each other the adjacent module (M) of domes (C) themselves defining in univocal fashion a reciprocal positioning distance; the interconnecting elements (10) being provided with a closing firewall (20 which can be coupled to each dome (C) facing along a channel (2) and at least two spacers (30) with a space between each other in order to leave the laying site free along the said channels (2), and provided with anchoring pins (32) for being anchored to two firewalls (20) facing each other determining the reciprocal positioning distance.
