Rectangular frame column construction method adopting template chamfering

Abstract

The invention discloses a rectangular frame column construction method adopting template chamfering. The construction method comprises the steps of bonding a steel reinforcement framework of one rectangular frame column and hoisting a middle formwork between the two rectangular frame columns; hoisting two side templates, and fixing a middle template with an end of a side template surface by usingfinish rolling deformed steel bars; hoisting an end template and fixing the end template with the side template surface in a cable-stayed manner; pouring concrete to form a rectangular frame column; and manufacturing another rectangular frame column according to the method and the like. The rectangular frame column construction method adopting template chamfering has the advantages that under thecondition that the two rectangular frame columns are arranged at a short distance, a separated construction and combined reinforcement mode is adopted, the machining difficulty of the template is reduced, the construction progress of the rectangular frame columns is accelerated, the construction period is shortened, conditions are provided for the pier column chamfering construction process, and the purposes of economical saving, quality guaranteeing and construction progress accelerating are achieved.

Description

technical field [0001] The invention belongs to the technical field of railway bridge construction, and in particular relates to a construction method of a rectangular frame column using formwork chamfering. Background technique [0002] At present, the piers on railway bridges with frame column net structure are divided into four types according to the cross-sectional size, namely 2.0m×1.7m, 1.5m×1.7m, 1.5m×1.5m, 1.7m×1.5m; According to the structural form, it is divided into three types: central column, corner column and side column. Among them, the cross-sectional size of the center column is usually 2.0m×1.7m. The distance between the center column and the center column along the bridge is generally 20.0m, and the distance between the center column and the center column is generally 11.3m. It can be seen that there is sufficient space for construction. At the same time, the scaffolding gap can also ensure the placement space of the pier column formwork. After the whole ...
