Assembling framework for temporary positioning of cast-in-place stand column reinforcement cage and construction method

Abstract

An assembly framework for temporary positioning of a cast-in-place stand column reinforcement cage comprises a plurality of positioning components connected in sequence, and the positioning components are connected in sequence to form an annular structure. The positioning component comprises vertically-arranged I-shaped steel and two positioning pieces connected to the upper end and the lower end of the I-shaped steel, and the two positioning pieces are arranged in parallel. The positioning piece is of a fan-shaped structure, and matching holes distributed at equal intervals are formed in the outer ring of the positioning piece. Compared with the prior art, the multiple positioning components which are arranged in an overhead mode are welded and fixed to the pile foundation reinforcement cage, so that the positioning components are located on the same horizontal height, an overhead supporting platform is formed by the multiple positioning components, the stand column reinforcement cage can be conveniently placed, and after an assembly framework is used, the assembly framework is dismantled; the device is used for positioning and mounting a next upright reinforcement cage, so that the recycling of materials is realized, and the field cost is saved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, in particular to an assembled skeleton for temporary positioning of cast-in-situ column reinforcement cages and a construction method. Background technique [0002] The construction of cast-in-place column is an important part of bridge construction. The construction of the positioning of the cast-in-place column reinforcement cage is an important link in the construction of the cast-in-place column. How to do a good job in the positioning accuracy and construction efficiency of the column reinforcement cage is directly related to the construction progress and construction quality of the bridge. question. [0003] Chinese Patent No. CN106760507A discloses a cast-in-situ column in civil construction and its construction method, including a column assembly, which includes a feed hopper, a base, a spacer column and at least two foundation columns, and the feed The bucket, a foundation co...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned cast-in-place column disclosed above generally achieves the purpose of positioning the reinforcement cage by swinging the column reinforcement cage by the truck crane during the installation process of the column reinforcement cage, which has the disadvantages of poor precision, long construction time, and high risk factor. Conducive to ensuring construction quality and saving construction cost
