Unilateral formwork erecting system of cast-in-site concrete arc outer wall body and construction method thereof

Abstract

The invention discloses a unilateral formwork erecting system of a cast-in-site concrete arc outer wall body and a construction method thereof. The construction method comprises the following construction steps: 1. setting an embedded part on a concrete floor slab below an arc wall body which is not cast; 2. pre-splicing an arc wall body formwork; 3. pre-splicing and mounting a unilateral support frame on site and fastening the unilateral support frame and the embedded part; 4. connecting the unilateral support frame and the arc wall body formwork; 5. setting up a scaffold required by the unilateral support frame; 6. adjusting, reinforcing and checking various parts; 7. casting arc wall body concrete between the arc wall body formwork and an arc outer wall body of an adjacent building; and 8. detaching the formwork after the concrete strength meets the specification requirement. The invention has the advantages of greatly shortening the construction period, saving labor force, reducing the construction cost and meeting the requirement of structural construction quality and is particularly applicable for wall body construction of automobile ramps, stadiums and other large-scale public buildings with arc structures.

Description

technical field The invention relates to an exterior wall formwork support system of a concrete building and a construction method thereof. Background technique In the construction of construction projects, the cast-in-place concrete exterior wall structure of underground projects has the characteristics of large wall thickness and high building floors. Single-sided arc walls are more common in underground garages. Due to site conditions, when there is no construction work surface between the exterior wall of the basement and the exterior wall of the adjacent construction project, the construction cannot be carried out according to the traditional double-sided formwork method, and the problems of lateral pressure and buoyancy of the formwork support system are difficult to solve. The traditional double-sided formwork not only requires a lot of turnover materials, but also has low efficiency and poor stability, which cannot meet the requirements of project quality and progr...
