Disposable formwork for two-way lightened voided slabs in reinforced concrete cast on site.
U-Boot Beton® is a recycled polypropylene formwork that was designed to create lightened slabs and rafts.
The use of U-Boot Beton® formwork makes it possible to create mushroom pillars, with the possibility to have the mushroom in the thickness of the slab.
Thanks to the conic elevator foot, immerging the U-Boot Beton® formworks in the concrete casting will create a gridwork of mutually perpendicular beams closed from the bottom and the top by a flat plate that is created with a single casting; this results in considerable reduction in the use of concrete and steel.
U-Boot Beton® is used to create slabs with large span or that are able to support large loads without beams.
Light and quick and easy to position, thanks to their modularity the designer can vary the geometric parameters as needed to adapt to all situations with great architectural freedom.
U-boot is used in all applications that require a plate structural solution, along with concrete-savings and therefore weight-savings. In tower buildings, weight-saving at every floor reduces load on foundations. The fact of avoiding beams being out of the slab thickness, enables the reduction of height for each floor. Therefore, a higher number of floors can be built. By using U-boot beton, it is possible to build thick raft foundations with a reduced quantity of concrete (and weight). U-boot is the ideal solution to create slabs of big spans and/or with a high bearing capacity. In case of difficult access to the building site or restructuring, U-boot beton permits to build up the horizontal structures without using lifting and movement devices, because of its stackability, modularity, lightness and manageability. The U-boot system particularly fits structures that need significant open spaces, like bureaus,industrial and commercial buildings, and civil constructions as well. The system also allows a more irregular distribution of pillars, since beams are not necessary.
