Construction device and method for pouring and reinforcing sectional steel hoop type concrete single column

Abstract

The invention discloses a construction device for pouring and reinforcing sectional steel hoop type concrete single column. The construction device comprises sectional steel member, battens, plywood and inserting pieces; each sectional steel member comprises a section steel body and a bending part, and the sectional steel members and the bending parts are integrally formed; a plurality of inserting holes are formed in each sectional steel body; the lower end of each inserting piece is small and the upper end of each inserting piece is large to ensure that the inserting pieces can be inserted into the inserting holes but cannot penetrate through the inserting holes; the sectional steel hoop comprises four section steel members, each section steel member is connected in an end to end mode, and the section steel members are fastened by the inserting pieces. Compared to a steel pipe external hoop adopted in a traditional construction project, an installation technology method of a frame column formwork which fixes steel pipes by using a split bolt inside, the compression resistance to the lateral pressure generated during concrete pouring is enhanced, and the slurry leakage and formwork expanding during traditional concrete pouring are avoided to a certain extent due to the lack of holes for the split bolt, the common problems of appearance quality problems such as serious slab staggering and the like of a frame column after pouring are avoided, and the molding size and impression of frame column concrete are ensured.

Description

technical field [0001] The invention relates to a house construction project in the field of engineering construction, in particular to a reinforcement device and method for pouring a frame column of a house construction project. Background technique [0002] Because the frame column formwork installation process in traditional construction projects mainly uses the outer hoop of the steel pipe for reinforcement, and the frame column formwork installation process method in which the steel pipe is fixed by tension screws inside. This reinforcement method has cumbersome procedures, consumes a large amount of turnover materials, and has an unsatisfactory appearance after casting. Especially for frame columns with large cross-sections, the lateral pressure is very large during the concrete pouring process, which results in a large amount of outer hoops for steel pipes, and a large number of fasteners need to be installed to match them. The process is cumbersome and affects the co...

Problems solved by technology

This kind of reinforcement method is cumbersome, consumes a lot of turnover materials, and the appearance after pouring is not ideal

Especially for frame columns with large cross-sections, the lateral pressure is very large during the concrete pouring process, which results in a large amount of outer hoops for steel pipes, and a large number of fasteners need to be installed to match them. The process is cumbersome
