Formwork for providing horizontal reinforcing bars exposed to concrete foundation elements, in particular plinths, plinths provided with such formwork, and structures comprising such plinths

摘要

The present invention relates to a formwork (10) for providing a concrete frame (103) and exposed horizontal reinforcement bars (101, 102) to a plinth (100), the formwork (10) comprising a base (11). The shape of the base 11 corresponds to the concrete mold 103 in plan view, and on each side of the base 11 extends vertically from the base to produce a casting chamber 16 for the concrete. Inner side lateral containment wall 12 and outer lateral containment wall 13 are provided, wherein the inner lateral containment wall 12 is provided with a plurality for insertion from the top of the plurality of longitudinal reinforcement bars 101. Openings 14, wherein at least one of the outer lateral containment walls 13 has a plurality of openings 15 for insertion by lateral sliding of the plurality of transverse reinforcing bars 102. And the openings 14, 15 are provided with the beam Expandable elements 20 are provided that are configured to transition from a contracted configuration in which rebars can freely slide in the openings 14, 15 to an expansion configuration in which the reinforcement bars are fixed in place, and the casting chamber 16 is watertight to prevent concrete from escaping during casting.
