<p>The system is used to form slabs on large surfaces, and is of the grid formwork type including a grid structure comprised of vertical braces (1), support bolsters (2), primary beams (3) and cross beams (4), all of which rest on the bolsters (2), with the cross beams (4) closing the grid and providing a stiffness to the structure that allows assembly of the entire grid structure and the later positioning of the formwork panels (5). The bolsters (2) are such that the support means for the beams can descend to a stripping position allowing to recover, before the concrete sets, both the beams and the panels (5). The longitudinal beams (3) are provided with supports for the panels (5), constructed such that they allow the panels (5) to hang vertically during the stripping operation. The cross beams (4) end at a profile made of rubber or the like (12) providing a means for sealing the grid, as well as for absorbing any possible clearances originated during the assembly of the panels (5).</p> |
