Template erecting method of floor post-cast strip and template used in method

Abstract

The invention discloses a template erecting method of a floor post-cast strip and a template used in the method. The template comprises a plate body of a rectangular-plate-shaped structure, wherein the middle of the plate body is provided with an opening extending to the bottom and penetrating through the front side and rear side of the plate body, the plate body is internally provided with a sliding groove, the sliding groove is communicated with the opening, the sliding groove is internally and slidably connected with two symmetrically arranged movable plates, each movable plate is providedwith an upper semicircular gap and a lower semicircular gap, and the semicircular gaps of the two movable plates cooperate to form a through hole allowing a reinforcing steel bar to pass through; oneside of the plate body is provided with elastic assemblies, each elastic assembly comprises a fixing part arranged on the plate body, a connecting part arranged on the corresponding movable plate anda tension spring connected between the corresponding fixing part and connecting part, the number of the elastic assemblies is two group, the movable plates are connected with the elastic assemblies respectively, the elastic force directions of the elastic assemblies connected with the two movable plates are opposite, and the tension springs are detachably connected with the connecting parts. The template erecting method of the floor post-cast strip and the template used in the method have the advantages that the template erecting and disassembling effects are achieved, and the template is noteasy to damage.

Description

technical field [0001] The invention relates to the technical field of post-cast belt construction, and more specifically relates to a formwork support method for a post-cast belt of a floor slab and a formwork used therefor. Background technique [0002] The post-pouring belt is a temporary part set at the corresponding positions of the foundation floor, wall and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. construction joints. The width of the post-cast tape is generally between 700mm-1000mm. The formwork needs to be supported during the construction of the post-casting belt, that is, the formwork is installed on both sides of the width of the post-casting belt to separate the concrete on both sides. For the post-cast construction of the floor slab, two layers of steel bars are usually bundled on the slab surface. The support of the tradition...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned formwork structure mainly has the following problems: the formwork width is relatively wide, and the mutual restriction is formed between the U-shaped card groove 19 and the X-axis reinforcement. When the formwork is removed, the formwork is difficult to take out from the dense reinforcement; the formwork in the prior art Some structures are cut and spliced ​​multiple times, the template is seriously damaged, and the service life is very low
