Construction method of pier column external wrapping weather-proof steel plate with section being straight line and circular curve combination

Abstract

The invention belongs to the technical field of bridge engineering, and particularly relates to a construction method of a pier column external wrapping weather-proof steel plate with a section beinga straight line and circular curve combination. The problems that after an existing pier column is constructed, a scaffold is erected on site so as to carry out weather-proof steel plate assembly andwelding, construction difficulty is large, risks are high, quality is not easily ensured, meanwhile, during steel plate welding work, the burning damage to the concrete is large, and the quality of the poured pier column concrete is seriously affected are solved. The method is easy and convenient to operate, rapid and stable, work is convenient and safe, the problems that after the existing pier column is constructed, the scaffold is erected on site so as to carry out weather-proof steel plate assembly and welding, construction difficulty is large, risks are high, quality is not easily ensured, a weather-proof steel plate and pier column are not tight, meanwhile, during steel plate welding work, the burning damage to the concrete is large, and the quality of the poured pier column concreteis seriously affected are solved, the application range is wide, and certain application and popularization value is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a construction method for a pier column whose section is a combination of a straight line and a circular curve and which is covered with a weather-resistant steel plate. Background technique [0002] The significance of traffic engineering to the world is self-evident, and bridges play a vital role in it, and the design of bridges is inseparable from piers. The cross-sectional shapes of piers are various, and the common ones are circular, square, and a combination of straight lines and circular curves. From the perspective of aesthetics and construction, pier columns with circular cross-sections have great advantages, but if there are upper tie beams, the construction difficulty of circular pier columns is obviously greater than that of square columns. Designers complement the advantages of the two, so that most of the pier columns at this stage adopt a cr...

AI Technical Summary

Problems solved by technology

[0005] The present invention solves the problem of erecting a scaffold on site after the construction of pier columns to assemble and weld weather-resistant steel plates. Not only is the construction difficult, the risk is high, and the quality is not easy to guarantee. At the same time, the steel plate welding work has a large burn damage to the concrete, which seriously affects the poured pier. In order to solve the problem of the concrete quality of the column, a construction method is provided for the pier column with a combination of straight line and circular curve section and weather-resistant steel plate
