The Introduction

The use of U-Boot Beton formwork makes it possible to create mushroom pillars, with the possibility to have the mushroom within the thickness of the slab. Thanks to the conical elevating 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 spans 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.

The ADVANTAGES

Traditional one way slab vs System optimised with U-Boot Beton


1. INCREASED NUMBER OF FLOORS

Possibility to gain floors at the same building height (towers) and building volume.

2. LARGE SPAN & GREAT ARCHITECTURAL FREEDOM

Larger spaces.

3. REDUCED SLAB THICKNESS

Thinner slabs but with equal loads and clearances, or bigger clearances with an equal thickness.

4. NO BEAMS BETWEEN PILLARS

Flat soffit for greater flexibility when installing systems.

5. REDUCTION IN THE NUMBER OF PILLARS – OPTIMISATION OF THE SECTION OF PILLARS

Facilitated use reallocation. Wider bays.

6. REDUCTION IN THE OVERALL LOAD .

OF THE STRUCTURE WEIGHING ON THE PILLARS AND THE FOUNDATION

7. REDUCED FOUNDATIONS – LESS DEEP FOUNDATION EXCAVATION

Lower costs for foundation excavations. Less excavation.

8. IMPROVED ACOUSTIC BEHAVIOUR

Less acoustic transmittance.



CHEAPNESS OF TWO-WAY LIGHTENED VOIDED SLABS U-BOOT BETON® SYSTEM

We are wrongly 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 thickness of the slabs only.

However, this does not show the various economic, practical and operational advantages provided with U-Boot Beton for the entire structure:

• less use of structural rebar in the slabs, pillars and foundation up to a total of 15% (also in the case of variants);
• less concrete is used in the foundations, columns and slabs;
• by reducing building weight antiseismic advantages are created;
• slimmer pillars and foundations, leading to lower costs related to excavation for foundations;
• also irregularly planning of pillars can be obtained to reflect the architectural freedom of the structure;
• reduction of work and overhead transfer of the formworks;
• plus other advantages in on-site logistics.
