Moulding unit for girder construction by means of quick-assembly systems

Abstract

The invention relates to a unit that comprises a closing piece arranged on a horizontal surface onto which side panels are secured, for which purpose the closing piece has side perforations arranged longitudinally and in line with projections that the side panels have on their lower edge. The side panels are vertically secured onto the closing piece via clips or the like secured onto the closing pieces. Thanks to the structural features of the parts and their engaging design, an assembly is obtained which is easy to assemble and dismantle, allowing girders to be built directly on site, as well as allowing the removal of forms from girders with complex geometries (holes, section reductions, etc.).

Description

FIELD OF THE INVENTION[0001]The invention relates, as established by the invention title, to a moulding unit for girder construction on site by means of quick-assembly systems, that is, it relates to the necessary pieces that act as a mould or formwork to construct girders on site.[0002]This invention is characterized by the special configuration and design of each and every piece that constitutes the set of necessary pieces, which enables the construction of girders directly on site in an easy, efficient, quick and handy manner, as well as the removal of forms from girders with complex geometries (holes, section reductions, etc.).[0003]Therefore, this invention is classified under the field of civil work and, particularly, under the methods used for the construction of girders.BACKGROUND OF THE INVENTION[0004]Concrete girders built on site are a widely extended system in the building industry and there are multiple solutions. The solutions known range from traditional wooden girder...

AI Technical Summary

Benefits of technology

[0010]This invention relates to a moulding unit for girder construction which simplifies the construction of girders directly on site.

[0012]In the case of building perforated girders, the frameworks can be placed in the first place thanks to the ease of turning of the system.

[0017]The mould removal process is quite simple. First, the closing pieces are removed and then the side panels. The unique structural features of the system enable the removal of forms from girders with complex geometries (holes, section reductions, etc.).

Problems solved by technology

The patent BE 1015307A3 relates to a modular system comprising base and side pieces, but which is difficult to disassemble.

The U.S. Pat. No. 3,288,427 relates to a system in which the beam formwork pieces form a leaning mould to facilitate the forms removal, but which requires more concrete consumption as well as a certain complexity in the set-up.

None of the formworks described above enable the building of perforated girders nor double-T girders.
