Abstract
Mould and improved system for building chambers that consists of a device for creating a casing formed by a set of two moulds, one outer and one inner, which adopt the form of the outer and inner walls respectively, of the chamber to be built by injecting concrete into the space formed between the two. Both moulds are characterised by being made up of longitudinal sheets that are joined together by hinges. the exterior mould (1) is formed by a set of sheets joined in this manner and with a clasp (9) between the first and the last, whilst the interior mould (2) is a closed structure with the sense of rotation of the alternating hinges and with an internal structure with a central axis (5) and transversal bars (6) which permits it fold like an umbrella to facilitate the demoulding. Finally the walls and sides of the moulds can be reinforced with folds and ribs.
