Abstract

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.

Dependent claims

Unit for the construction of slab foundations, the unit comprising:

a plurality of modules of domed bodies made of plastic material and which are suitable for being placed in position in a construction site with a concavity turned towards the construction site and in conformity with modules (M) of at least one domed body arranged laterally in relation to each other;
a plurality of channels formed by the modules of the adjacent domed bodies and which are suitable for being filled with aggregating material in order to form bearing beams;
and
a plurality of interconnecting elements arranged in an intermediate position between at least two adjacent Modules of domed bodies to connect to each other the adjacent modules of domed bodies defining a reciprocal positioning distance;
wherein said interconnecting elements comprise one of two firewalls connected to respective domed bodies facing each other along said channels and spacing means interposed between the two firewalls to transmit the static load of the bearing beams directly onto the site where they are to be laid and to determine the reciprocal positioning distance.
