Benefits of technology

The invention is a device for making girders on site that makes it easier to build them. It can be used to create perforated girders by putting frameworks in place. The device has a unique design that makes it easy to remove the forms from the girt with complex shapes.

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.

Embodiment Construction

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

[0011]Unlike other girder formwork systems, all the pieces are fitted via clips; the pieces do not require any adjustment before being fitted and they are designed in an easy-to-handle format.

[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.

[0013]The moulding unit comprises a closing piece placed 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.

[0014]The side panels fit together by means of an angular or swinging movement. For this purpose, both the projections and the perforations have a rounded edge on their inner faces.

[0015]The side panels are vertically secured onto the closing piece via cl...

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...
