Fastening system for concrete rectangular column formwork and construction method of concrete column

Abstract

The invention relates to the technical field of concrete buildings, in particular to a fastening system for a concrete rectangular column formwork and a construction method for a concrete column. Wherein, the fastening system of the concrete rectangular column formwork includes a fastening frame, a connecting mechanism, a first driving mechanism, a second driving mechanism, a second fixing mechanism and a first fixing mechanism; the number of fastening frames is multiple, and the connecting mechanism It is used to keep multiple fixed frames relatively fixed; the fastening frame has a fastening channel, the caliber of which is adjustable, and the fastening channel is used for fastening the formwork. The invention has the following effects: 1. The fastening system of the concrete rectangular column formwork has the advantage of making the concrete rectangular column formwork difficult to deform; 2. The fastening frame can fasten the formwork of different sizes, and has strong versatility; 3. The concrete The entire rectangular column formwork is subjected to relatively uniform pressing force, so that the concrete rectangular column formwork is relatively smooth, and the side wall of the formed concrete column is relatively smooth.

Description

technical field [0001] The invention relates to the technical field of concrete buildings, in particular to a fastening system for a concrete rectangular column formwork and a construction method for a concrete column. Background technique [0002] At present, the building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct positions, and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce engineering costs. When pouring concrete columns, the formwork is usually built first, then the formwork is fixed by a fastening system, and then concrete is poured in the formwork, and the formwork is removed after the con...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: since each wooden square pressing plate rod only compresses the part on one side of the formwork, the two ends of the formwork on one side may be offset. When the force is uneven, the joints of the formwork on both sides will be cracked wider, so that the mortar in the concrete formwork will flow out along the joints when pouring concrete mortar, resulting in deformation of the final formed concrete column
