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

Abstract

The invention relates to a fastening system of a concrete rectangular column formwork and a construction method of a concrete column. The fastening system comprises four bottom frames and four sets of fastening pieces, the four bottom frames are in one-to-one correspondence with four panels, the bottom frames are fixed to the outer sides of the lower ends of the corresponding panels, and the four sets of fastening pieces are in one-to-one correspondence with the four bottom frames; each set of fastening pieces comprises a vertical rod vertically connected to the corresponding bottom frame and a plurality of transverse rods rotationally connected with the vertical rod, the multiple transverse rods are distributed in the length direction of the vertical rods, and the transverse rods are attached to the outer sides of the corresponding panels; clamping grooves are correspondingly formed in the two ends of the transverse rods, and when all the transverse rods rotate to the horizontal state, the adjacent transverse rods located at the same height are mutually clamped and fixed through the clamping grooves in the end parts of the transverse rods; and the vertical rods are provided with linkage pieces for driving the transverse rods to swing synchronously. The fastening system has the effect of improving the formwork mounting efficiency.

Description

technical field [0001] The application 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] With the continuous development of society, there are more and more building constructions, and in building construction, the use of building formwork is particularly extensive. [0003] In the related technology, the concrete formwork can be made according to the design requirements, so that the concrete structure can be formed according to the specified position and geometric size. The concrete formwork is mostly a wooden panel. The wooden panel is erected and surrounded by the column reinforcement, and then passed through the wooden formwork by the pull bolts, and fixed on the erected keel frame. [0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: since th...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: since the building formwork has a certain height, in order to make the formwork evenly stressed, the tension bolts are distributed at equal intervals along the height direction of the formwork. When installing the high tension bolts, Scaffolding is required, which affects the efficiency of formwork installation, so there is still room for improvement
