A construction method for post-casting belt formwork of cast-in-place slabs by using formwork jacking tools

Abstract

The invention discloses a formwork jacking tool for constructing a post-cast strip of a cast-in-place slab and a formwork supporting construction method. The formwork jacking tool for constructing the post-cast strip of the cast-in-place slab comprises a jack, an adjustable supporting nut, at least one bracket and an adjustment nut. The jack comprises a screw and a supporting plate A arranged at the top end of the screw, wherein nail holes are formed in the supporting plate A. The adjustable supporting nut comprises a nut body, wherein two supports are symmetrically arranged on the outer side of the nut body, sliding grooves which are arranged in the axial direction of the nut body are formed in the supports, and a U-shaped clamping ring which is connected with the corresponding support is arranged on the outer side of each sliding groove. Each bracket comprises a dorsal rib which is in the shape of a right trapezoid, a supporting plate B is fixed to the big end of the right-trapezoid-shaped dorsal rib, and sliding rails are arranged on the two side faces of the dorsal rib respectively. The brackets are connected with the sliding grooves in the supports in a matched mode through the sliding rails, the U-shaped clamping rings are matched with the oblique edges of the dorsal ribs of the brackets so as to fasten the brackets, the adjustable supporting nut is connected with the screw of the jack in a matched mode through the nut body, and the adjustment nut is connected to the lower portion of the screw through threads.

Description

technical field [0001] The invention relates to a formwork support tool, in particular to a formwork jacking tool used in the construction of cast-in-place slab post-pouring belts. The invention also relates to a construction method of using the tool to support the cast-in-place slab post-cast belt formwork. Background technique [0002] At present, the general technology of cast-in-place slab (top slab) post-cast belt formwork support can be divided into the following two types: 1. A formwork support system is separately set up at the post-cast belt of the cast-in-place slab (top slab). The formwork support system of the component is disconnected; 2. First set up the formwork support system of the structural members on both sides of the post-casting belt, and pour the concrete on both sides of the post-casting belt. The structural members on both sides are backed up with vertical poles, and the formwork support system of the post-casting belt is set up separately before th...
