Post-cast belt structure and construction method

Abstract

The invention relates to a post-cast strip structure and a construction method. The construction method comprises the following steps: arranging an independent supporting body formed by a bottom column supporting plate and a back removal bottom column on the lower part of a back removal bottom mold and arranging a pouring platform column and a hoop side supporting beam on the back removal bottom mold to form a concrete pouring construction platform on a first-removal mold plate; arranging a flexible connecting bar between an upper folding plate and a lower folding plate and enhancing the transverse rigidity of a floorslab side mold through a reinforcing insertion plate; closing the upper part of a channel of the post-cast strip by a cap sealing coiled material and a coiled material rib plate, and closing two ends of the channel of the post-cast strip by a suspended supporting rod and an end closing body to close the post-cast strip at multiple angles; sliding a scraper blade cross beamand a rigid scraper blade along the upper surface of post-cast concrete; and arranging a steam pipeline on the lower surface of a steam curing bracket and a closed tarpaulin on the outer side to maintain the post-cast concrete with steam. The post-cast strip structure can improve the post-cast strip mold plate supporting quality and efficiency and the concrete pouring construction quality and efficiency and improve the stress performance of the construction structure and protect the construction environment.

Description

technical field [0001] The invention relates to a post-cast belt structure and a construction method that can improve the quality and efficiency of post-cast belt formwork support and concrete pouring construction, improve the mechanical performance of the construction structure, and protect the construction environment. It belongs to the field of construction engineering and is suitable for post-cast Cast belt structure construction works. Background technique [0002] In the process of concrete hardening, large temperature stresses are often generated, and even a certain amount of differential deformation may occur. For this, post-casting belts are often installed at appropriate positions in the project. In the post-cast belt structure engineering, the support quality of the formwork, the layout of the cover, and the construction effect of the closed pouring are often the focus and difficulty of the engineering control. [0003] In the prior art, there is a formwork struc...
