Unit for the construction of slab foundations

摘要

A unit (1) for the construction of slab foundations, the unit (1) includes modules (M) of domes (C) 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 to form a gridwork of channels (2) which are engaged by reinforcing bars or sheaths (F). Interconnecting elements (10) are arranged in an intermediate position between at least two adjacent modules (M) of domes (C) to connect to each other the adjacent module (M) of domes (C) defining a reciprocal positioning distance. The interconnecting elements (10) are 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 channels (2), and provided with anchoring pins (32) for being anchored to two firewalls (20) facing each other determining the reciprocal positioning distance.
