PRODUCTION AND MOLDING SYSTEM OF ELEMENTS OF CEMENT MATRIX, REINFORCED WITH GLASS FIBER

Abstract: The present invention refers to the production and molding system of tridimensional elements of cement matrix, reinforced with glass fiber, in order to achieve tridimensional elements (4, 5, 6) using a combination of special materials, a structure combined with glass fiber (1) (mesh type) with a mixture of cement base paste with polymers (3) and reinforced with a resistant alcali glass fiber (2). The invented system permits an easy mechanical production of tridimensional elements (4, 5, 6) either moulded or sprayed (projected), for small thickness (from 6 to 20 mm). The tridimensional elements thus produced can be used either separately or in multi-layer elements connecting the mono-layer elements through non-rigid links (8). The created space between the two mono-layer elements (7) will be filled in with Perlite type of material, in order to promote the thermal insulation of the wall thus built.

Description: DESCRIPTION "PRODUCTION AND MOLDING SYSTEM OF ELEMENTS OF CEMENT MATRIX, REINFORCED WITH GLASS FIBER " The present invention patent refers to a production and molding system of tridimensional elements of cement reinforced with glass fiber. The execution of the elements (4,5,6) is carried out using a combined structure added with glass fiber (1) (mesh type) together with a mixture of a cimenticious paste added with polymers (3) and reinforced with a resistant alcali glass fiber (2). The existing technology presently permits the construction of panels for building facades only and the execution of bidimensional parts such as cornices, and other small elements used in the adorning of facades. The existing technology consists in spreading horizontally over a mould a cement base paste added with polymers and reinforced with a resistant alcali glass fiber. This technology permits to produce bi-dimensional elements. This invention is based on the construction of tridimensional elements (4.5,6) moulding the elements in a vertical and horizontal position with cement paste added with polymers (3) and reinforced with a resistant alcali glass fiber (2), having for such used a combined structure with glass fiber (1) (mesh type). The system uses tridimensional highly accurate metallic moulds where the structure will be combined with glass fiber (1) and subsequently projecting over this structure the cement paste added with polymers (3) reinforced with a resistant alcali glass fiber (2). In a first stage action, the combined structure with glass fiber (1) (mesh type) has the purpose of fixing up the cimenticious paste added with polymeers (3) and reinforced with a resistant alcali glass fiber while this one does not reach the resistance characteristics. As soon as the cimenticious paste reinforced with glass fiber reaches the setting stage an homogeneous composite is formed. The invented system permits the easy mechanical execuction of the tridimensional elements (4,5,6) either moulded or projected, for small thickness (from 6 to 20 mm) and allows to control and adjust the stress resistance generated in the tridimensional elements, due to the dimensional variation as a result of rectraction, thermal variation and mechanical action. The tridimensional elements (4,5,6) thus produced can either be used separately or in multilayers (sandwich) elements binding the two mono-layer elements through non rigid links (8) using for such an expansive agglutinant material between the two layers. This material (8) has the particularity of hardening the two mono-layer parts allowing hence a certain flexibility between them. The space created between the two mono layer parts will be filled up with Parlayed type material (7) which will promote the thermal insulation of the wall thus built.
