Construction method and steel bar skeleton for bridge pier pier body reinforcement

Abstract

The invention discloses a bridge pier body reinforcement construction method and reinforcement frameworks. The bridge pier body reinforcement construction method comprises the following steps of S1, building a bracket; S2, manufacturing the reinforcement frameworks; S3, installing the bottom reinforcement framework; S4, installing the upper reinforcement framework; S5, installing pier body reinforcements. The bridge pier body reinforcement construction method has the advantages that the positioning of the pier body reinforcements is accurate, and the positioning speed is high; the integral stability of a pier body reinforcement cage is good, and the easiness in vertical position deviation and whole torsion is avoided; the installation quality of a formwork and the form erection speed are improved, and the like; each reinforcement framework comprises two semicircular positioning reinforcements and two transverse reinforcing ribs, the two transverse reinforcing ribs are arranged in parallel, the two semicircular positioning reinforcements are respectively arranged at the two ends of each transverse reinforcing rib, and the two ends of each semicircular positioning reinforcement are respectively welded with one transverse reinforcing rib. The reinforcement framework has the advantages that the structure is simple, the assembly speed is high, the whole stability of the pier body reinforcement cage is improved, and the like.

Description

technical field [0001] The invention relates to a bridge pier construction method and device, in particular to a construction method and a steel bar skeleton for a bridge pier pier body reinforcement. Background technique [0002] With the rapid development of my country's economy, my country's high-speed railway industry also has an unprecedented momentum of vigorous development. The continuous improvement of vehicle speed puts forward higher requirements for the construction quality of railway bridges. The function of the bridge pier is to transmit and release the load borne by the bridge superstructure, which is an important part of the bridge structure. Therefore, the construction design and construction quality of the pier Of course, there are higher requirements. Accurately installing and fixing the steel bars of the pier body is the key point to ensure the effective thickness of the concrete cover of the bridge pier body and improve the construction quality of the pi...

AI Technical Summary

Problems solved by technology

[0004] (1) The positioning of the pre-embedded steel bars in the pier body is difficult and inaccurate, which will affect the installation progress and quality of the pier body steel bars

[0005] (2) After the bowl buckle support for construction is removed, the steel bars of the pier body will deviate from the vertical position due to insufficient overall rigidity, and even the overall distortion will occur. The overall distortion of the pier body steel bars will affect the quality and progress of the pier body formwork , the effective thickness of the concrete cover cannot be guaranteed

[0006] (3) For higher pier bodies, the steel bars of the pier body will affect the installation speed and positioning quality due to the lack of supporting force points, and it is necessary to erect tension bars along the reinforcement cage of the pier body to fix them, and the stabilizing effect is not good
