Formwork setting up method for floor post-cast strip

Abstract

The invention discloses a formwork setting up method for a floor post-cast strip. The formwork setting up method comprises the following steps that step one, positioning and line drawing are conducted; step two, floor steel bars are bound; step three, Z-axis steel bars are welded to the upper layer X-axis steel bars and the lower layer X-axis steel bars on the two sides of the post-cost strip, and the welding positions of the Z-axis steel bars are on the opposite sides of the upper layer X-axis steel bars and the lower layer X-axis steel bars; step four, formworks are mounted on the two sides of a post-cast strip part and connected between the adjacent X-shaft steel bars in a clamped mode and abut against the Y-axis steel bars, and the Z-axis steel bars are connected with the side walls of the formworks in an abutting mode; step five, battens are mounted on the sides, facing the post-cast strip part, of the upper sides and the lower sides of the formworks, attach to the formworks in an abutting mode and close the gaps of the connecting positions of the upper sides and the lower sides of the adjacent formworks; and step six, detachable supporting components are mounted between the battens of the two sides of the post-cast strip part to fix the battens and the formwork. By adoption of the formwork setting up method, formwork setting up and dismantling are facilitated, and meanwhile, the fixing strength and the anti-leakage capacity of the formworks are effectively guaranteed.

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 floor post-cast belt. 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 traditional formwork is carried out simultaneous...

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 12 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
