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.

Abstract: A Disposable casing (1) is for thermally insulated walls in reinforced concrete. The casing (1) is provided with two main panels (2) which face each other and are limited towards the outside by respective lateral surfaces (2e), and with at least two casing spacers (3) which are interposed between the two main panels (2) in order to maintain the two main panels (2) at a determined distance from each other. At least one supplementary panel (5) is arranged against/abutting (a ridosso) the lateral surface (2e) of a respective main panel (2) and connecting elements (7) which are interposed between the supplementary panel (5) and the relative main panel (2)in order to render the supplementary panel (5) and the relative main panel (2) integral with each other.

Abstract: Disposable framework (1) for insulated masonry in reinforced concrete, is provided with two polystyrene panels (2) which face each other and which are limited towards the outside by respective lateral surfaces (2e), and with at least two formwork spacers (10) which are assembled to the polystyrene panels (2), and presenting respective pairs of terminal end plates (19), which extend in such a way as to abut the ralative lateral surfaces (2e) and which partially occupy a height of the lateral surfaces (82e).
