Tool type concrete composite slab cast-in-situ connecting section formwork supporting device

Abstract

The invention discloses a tool type concrete composite slab cast-in-situ connecting section formwork supporting device. The tool type concrete composite slab cast-in-situ connecting section formwork supporting device solves the problem that existing concrete composite slab cast-in-situ connection adopts a hanging formwork or a traditional full-hall support method and the problems that connection section formwork support and prefabricated part support interfere with each other, supporting materials are large in dosage and the mounting accuracy and installation quality of the formwork are difficult to guarantee exist. Two supporting stand column inserting holes are formed in the middle portion of a supporting cross beam, two transverse adjusting pieces are symmetrically arranged at the two ends of the supporting cross beam, the transverse adjusting pieces are connected with the supporting cross beam in a threaded mode, two supporting stand columns correspond to the two supporting stand column inserting holes in a one-to-one mode, and the supporting stand columns are connected with the supporting cross beam in an inserting mode. Vertical adjusting pieces are connected to the upper ends of the supporting stand columns in a threaded mode, U-shaped brackets are connected to the upper ends of the vertical adjusting pieces in a threaded mode, the U-shaped brackets are internally provided with formwork supporting beams, and a bottom formwork is arranged above the two formwork supporting beams. The tool type concrete composite slab cast-in-situ connecting section formwork supportingdevice is used in the construction of fabricated composite concrete floor.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork support device for a tool-type concrete composite slab cast-in-place connection section. Background technique [0002] The concrete laminated floor is different from the fully cast-in-place concrete floor. The bottom is prefabricated, and the upper part is laid with pipelines and cast-in-place laminated concrete forms the overall floor. [0003] During installation and construction, the prefabricated part is used as the base form of the upper cast-in-place part, and it is not necessary to set up full support and formwork like the full cast-in-place concrete floor slab, only the support is sufficient. However, the prefabricated part of the laminated slab is restricted by factors such as transportation conditions and component stiffness during transportation and hoisting. Therefore, the formwork support system of the cast-in-place connection section of the...
