Abstract

Abstract

The new-type grille composite formwork is composed of integral aluminum alloy grilles， plastic templates and adjustable supports. Taking the integral aluminum alloy grille as the object， experimental study and finite element analysis of its flexural performance were carried out under vertical uniformly distributed loads. The results showed that the bending deformation and stress test data of the grille were basically consistent with the finite element calculation results， so the application scope of the grille was determined， that is， it would be suitable for the formwork construction of the concrete floor with thickness less than 350 mm. Its maximum bearing load was 8.79 kN/m²， which was controlled by the secondary ridge stiffness. On this basis， according to the force characteristics of the grille， a simplified calculation method， which is easy to apply， safe and feasible， was proposed. This method could quickly evaluate the force state of the grille.
