17-boot beton 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...

System optimised with U-Boot Beton 11 Increased number of floors Possibility to gain floors at the same building height (towers) and building volume. 5 OPTIMISATION OF THE SECTION OF PILLARS REDUCTION IN THE NUMBER OF PILLARS Wider bays. Facilitated use reallocation. 2 LARGE SPAN AND GREAT ARCHITECTURAL FREEDOM Larger spaces. 3 REDUCED SLAB THICKNESS Thinner slabs but with equal loads and clearances, or bigger clearances with an equal thickness. 6 REDUCTION IN THE OVERALL LOAD OF THE STRUCTURE WEIGHING ON THE PILLARS AND THE FOUNDATION 7 LESS DEEP FOUNDATION EXCAVATION Lower costs for...

Real advantages We are incorrectly led to estimate the advantage of a slab lightened with U-Boot Beton® limiting it to a mere comparison between savings in concrete and the cost of the formwork on the level of the slabs only. In this way however, as the analysis is immediate and intuitive, it does not account for the various economic, practical and operational advantages provided with U-Boot Beton® for the entire structure: less use of iron in the slabs, pillars and foundation up to a total of 15% (also in the case of variants); less concrete is used not only for the slabs but also for the...

Applications U-Boot Beton® is used in all applications that require a structural plate together with the need to use less concrete and therefore for a lighter structure. U-Boot Beton® is the ideal solution for creating slabs with a large span and/or great load-bearing capacity: it is particularly suited for structures that require considerable open spaces, such as executive, commercial and industrial buildings as well as public, civil and residential structures. It makes it possible to more irregularly distribute the pillars, as beams do not need to be created. In the case of yards that are...

Beams in the slab thickness - The spacer joint The U-Boot Beton® lightened plate slab has a perpendicular beam gridwork of the same thickness as the slab that transfers all stresses directly to the pillars around which it will suffice to leave a full zone of variable dimensions based on the shearing forces. Beam dimensioning and their perfect implementation on site depends on the orderly and precise layout of the lightening elements during installation but especially during casting. Correct positioning of the U-Boot Beton® is guaranteed by an effective rigid spacer joint with graduated...

Installation REINFORCEMENTS LOWER REINFORCEMENT SIDE SHUTTERING TRADITIONAL SHUTTERING IN WOOD OR METAL REINFORCEMENTS SIDE SHUTTERING 1 The entire surface of the slab to be cast on site is shuttered with wood 2 The U-Boot Beton® formworks are positioned using the lateral deckings (or similar systems), then the lower reinforconcrete bars are positioned in two mutually perpendicular directions according to the design and the lattice for the upper reinforconcrete is arranged. spacers joints to place them at the desired centre distance that will determine the beam width. Thanks to the conic...

Application examples: rafts Among the various foundation types, rafts are one of the most well known. They are used above all in ground conditions with little bearing capacity, or with poor quality soil, large thicknesses must be used which increases the construction cost. Thanks to the use of U-Boot Beton® lightened rafts can be created with the same performance but at a considerably lower cost. Once drown in the concrete casting, U-Boot Beton® forms the structure just like two full slabs, with a variable thickness, connected by a perpendicular beam gridwork to form a bidirectional static...

U-Boot Beton®: excellence The quality of the used mixture, the innovative shape, the thicknesses and dimensions of the product, the fire safety and strict working techniques make it a product of excellence. U-Boot Beton®, is not subject to deformations, either during or after the casting, either due to the weight of the concrete or the dynamic effect connected to the work operations: it is able to support before casting the workers and fresh concrete, the pressure created during the compression and vibration of the casting, the weight of people, reinforconcretes and equipment guaranteeing...

Environmental compatibility Daliform Group has again demonstrated to be extremely precise with regard to respecting health and the environment having been the first to obtain Environmental Compatibility Certification (CCA) for its products. This certificate is very important for U-Boot Beton® because it demonstrates: the lack of dangerous substances in its composition (even if recycled materials are used); the lack of emissivity of toxic substances during the various phases of the product's life and operating cycle, which benefits the health of the intermediate users (production and...
