Pier stud vertical back cage platform channel construction method and back cage platform channel device

Abstract

The invention discloses a pier column vertical back cage platform channel construction method which comprises the following steps: (1) breaking pile head concrete according to design requirements, andexposing a pile foundation reinforcement cage; and (2) mounting a pier column reinforcement cage, mounting a back cage framework in the side surface of the pier column reinforcement cage before the pier column reinforcement cage is mounted and hoisted, hanging hooks on reinforcing ribs of the pier column reinforcement cage, and enabling the position of the back cage framework to coincide with a single semicircular template. The vertical back cage platform device is alternately provided with an overturning platform and a stepping rod, constructors can climb and construct on the overturning platforms conveniently, the safety problem existing in unhooking bare climbing of the reinforcement cage is solved, and the safety is high; the hooks are arranged and erected on the reinforcing ribs of the reinforcement cage and the formwork, dismounting is convenient, the overall hoisting mounting and dismounting speed is high, the working efficiency of workers is improved, meanwhile, safety facilities such as a steel pipe support or a pier body protection frame are replaced, the safety management problem of the highway bridge pier stud construction support is solved, the process is simplified,and operability is high.

Description

technical field [0001] The invention belongs to the field of pouring methods and devices for cylindrical high piers, and in particular relates to a construction method for a vertical back cage platform channel of a pier column and a back cage platform channel device. Background technique [0002] The history of human development is the history of architectural development. As human beings continue to develop, architecture continues to move forward. With the acceleration of modernization and urbanization and the rapid development of my country's infrastructure technology, large-scale circular pier buildings are becoming more and more common. In the traditional round pier column building, the outer frame is erected by the bracket method, which has great safety hazards in the process of installation and dismantling. With the progress of the industry, ring-shaped platforms and shaped pier protective frames are used in some constructions. However, the purchase cost of protective...

AI Technical Summary

Problems solved by technology

In the traditional round pier column building, the outer frame is erected by the bracket method, which poses great safety hazards in the process of installation and dismantling

With the progress of the industry, ring-shaped platforms and shaped pier protection frames are used in some constructions, but the purchase cost of the protection frames is high, and the installation and disassembly efficiency is extremely low, so it is difficult to popularize and apply in the road construction industry

At present, the phenomenon of cranes carrying people in cages and climbing steel cages and formworks often occurs in the construction of cylindrical high piers. Solving this phenomenon has always been a difficult problem in the road construction industry, resulting in frequent safety accidents in high-altitude operation of pier columns.
