Title:
METHOD AND REINFORCEMENT FOR MAKING MULTILAYER CONSTRUCTION ARTICLES
Document Type and Number:
WIPO Patent Application WO/1992/010345
Kind Code:
A1
Abstract:
A method for making multilayer construction articles consists in transforming the bottom (1) of a mould (2) into a vacuum mould plate (5) on the surface of which are consecutively placed a reinforcing grid (3) with anchor elements (8), a first layer (12) of a hardening material, a hydroinsulation layer (14) and a second layer (17) of the hardening material with its subsequent consolidation. After the placement of the hydroinsulation layer (14) a closed chamber formed between the latter and the vacuum mould plate (5) is evacuated. Then, the second layer (17) of the hardening material is placed. The vacuum in the closed chamber is maintained until the end of the placement and consolidation of the second layer (17) of the hardening material. A reinforcement for multilayer construction articles comprises a reinforcing grid (3) with anchor elements (8) consisting of bars arranged equidistantly in relation to the plane of the reinforcing grid (3). The loose ends (10) of the bar anchor elements (8) are bent out along a curve in the direction of the plane of the grid (3). The invention may be used for construction of water-proof and gas-proof parts of buildings and constructions.
