PRECAST PAD FOR SHALLOW FOUNDATION
The Precast Foundation is a reinforced concrete element made up of a tied rebar beam cage incorporated within a semi-precast concrete element which acts as formwork. The geometric dimensions and the steel area are established through static calculations elaborated according to the distributed of loads N, Mx, Tx, My, Ty and the pt pressure admissible on the terrain.
The Precast Foundation can be produced in different forms and dimensions to satisfy every design and structural need.
The jutting out reinforcements at the head of the pile are incorporated within the footing base through the pouring of concrete.
For the assembly and alignment of the precast column, adjusting devices are used. These allow an easy, fast and precise installation.
During the production phase of the Precast Foundation, four anchor bolts are left within the central concrete walls, while the precast column is equipped with eight threaded coupler. The adjusting devices are fixed to the anchor bolts using nuts and to the precast column using bolts.
This system not only allows the precast column to be aligned with pinpoint precision, but also eliminates any kind of shoring during assembly.
The four connections will be dimensioned in relation to the weight and other strains to which the column is subject and are used merely for assembling the elements. When the concrete inside of the Precast Foundation has cured, all the adjusting devices are removed.
