Embodiment Construction

[0027] see figure 1 and figure 2 , the large-span prefabricated beam floor formwork system provided in the present invention includes a floor formwork 1, a truss 2 and a resting rod 3 supporting the truss 2, a grid 9 is laid on the truss 2, and the floor formwork 1 is laid on the grid 9, the prefabricated beam 4 is provided with a formwork hole 41, the formwork hole is provided with a connecting piece 42, and the resting rod 3 is installed on the prefabricated beam 4 through the connecting piece 42 . In the present invention, formwork holes 41 are provided on the prefabricated beam 4, through which the truss 2 and the floor formwork 1 are installed. Therefore, there is no need to set the ground support scaffolding at the bottom, which not only saves formwork support members, but also reduces the cost of the upper floor. The load will not be transferred to the lower floor, and the formwork of the lower floor can be removed earlier than the completion of the upper floor, ther...

Abstract

The invention discloses a long-slab-span prefabricated beam floor formwork system, which comprises a floor template, a truss and a placement rod for supporting the truss, wherein a grille is laid on the truss; the floor template is laid on the grille; a formwork hole is formed on a prefabricated beam; a connecting piece is arranged at the formwork hole; and the placement rod is arranged on the prefabricated beam through the connecting piece. In the system, the formwork hole is formed on the prefabricated beam; the placement rod is arranged through the formwork hole; the truss is arranged on the placement rod; the floor template is erected on the truss, and a landing supporting scaffold is not required to be arranged at the bottom of the floor template; and thus, a template supporting member is saved, load of an upper layer floor is not transferred to a lower layer floor, a lower layer floor template can be dismantled before completion of construction of the upper layer floor, and accordingly, the turnover efficiency of the template is increased.

Description

technical field [0001] The invention relates to a formwork support structure for building a building structure system, in particular to a large-span prefabricated beam floor formwork support system. Background technique [0002] In the prefabricated cast-in-place system, laminated slabs are generally used for floor slabs, and floor formwork and support frames are omitted, but this system is expensive and poor in integrity. When the floor slab is cast-in-place, how to make the floor slab formwork simple, fast and low-cost, without the need for formwork and floor support frames is a problem that must be solved for the new prefabricated cast-in-place system. [0003] However, in the prior art, the traditional floor support frame is generally used for supporting the cast-in-place floor, and the upper load is transmitted to the lower floor through the floor support frame. Therefore, the lower floor formwork must be completed after the upper floor is constructed and reaches a cert...
