FR2482641A1 - Building construction using steel and concrete mixture - has bent steel panels forming shutters for load-bearing reinforced concrete - Google Patents

Abstract

The prefabricated galvanised shutters are permanent and not withdrawn and form columns, beams and lintels as well as shutters for the concrete. They also provide a framework for the exterior joinery. Interior and exterior insulating panels are fixed to them by self tapping screws or hooked nails. The exterior fill panels have outside and inside skins separated by insulating while the interior fill panels have a skin glued onto insulation, the assembly assuring continuity in the thermal insulation while using different insulating materials.

Description

The present invention relates to the use of prefabricated metal panels in the factory, mounted on site, stiffened by pouring Breton and completed by filling elements leading to the rapid construction of individual houses, in strips, collective housing, industrial premises , commercial or for office use on one or more levels,
Panels made of folded galvanized sheet are prefabricated in the workshop and group together the formwork functions for intermediate posts (1), angle (2), for chaining (3), secondary shoring (4) of the main framework, support (5) of the pre-frames of the exterior joinery and support (6) of the exterior and interior filling and insulation elements. The supports (4) and (6) can be confused.

The panels can be joined or not (variable side) and allow great dimensional adaptability.

The formwork thus produced is filled, after installation of any traditional reinforcements, with cement concrete and serves as a supporting framework for roofing or higher levels (P actions) and stability elements (actions F) for the whole construction. Fig. 2
The fillings of the exterior and interior facings are then made from panels of variable nature but each with their own insulation. The exterior panels can be sandwich type (7) with polystyrene or ployurethane in the center and faces in particle board, plywood, particles agglomerated with cement or other binder, steel sheet. They can have a finished surface finish or even serve as a support for finishing plaster. The interior panels have polystyrene or polyurethane insulation and a facing in particle board, plywood, particles agglomerated with cement or with another binder, steel sheet, plasterboard. They may have a finished surface finish or serve as a support for interior finishes (9) of the plaster, paint, fabric or upholstery type.

Claims (5)

REVF, NICATIONS 1. Construction method usable for individual, strip or collective dwellings, for commercial, industrial premises or for office use on one or more levels using prefabricated metal panels serving both as a formwork lost for a load-bearing framework of reinforced concrete and also of support for exterior carpentry frames and support for exterior and interior filling elements, characterized in that the panels are made of folded galvanized sheets, or any other material having equivalent technical characteristics, connected together by welding or gluing, on which are fixed by tacking nailing or self-tapping screw the filling and insulation elements. 2. Method according to claim 1 characterized in that the panels are not necessarily contiguous, adaptation to variable dimensions is possible, the continuity of reinforced concrete framework being ensured by the chaining covering the panels and making "bridge" on the voids. 3. Method according to claim 1 characterized in that the exterior filling elements are panels comprising an interior skin and an exterior skin separated by insulation and that the interior filling elements are panels comprising a skin bonded to an insulation, this this assembly ensuring perfect continuity in thermal insulation. 4. Method according to claim 1 characterized in that for the same dimension of the finished complex it is possible to obtain different insulation values by varying the folding dimensions of the tolerants. 5. Method according to claim 4 characterized in that the external and internal filling elements can be of very different nature and based on wood, ttle, plaster, plywood, particle agglomerates with glue or cement or any other material with equivalent technical characteristics *.
