A Construction Method of Large Section Concrete Y-shaped Column

Abstract

The invention discloses a method for constructing a large-section concrete Y-shaped column. The method comprises following construction steps of (1), plane positioning and space line position construction survey; (2), reinforcing steel bar engineering; (3), reinforcing steel bar binding; (4), mounting of an inclined column template; (5), mounting of an inclined column supporting system; and (6), concrete casting. The method for constructing the large-section concrete Y-shaped column achieves the binding relation between inclined column main ribs and stirrups, the reinforcing steel bar binding meets the requirement of the large-section concrete inclined column, stirrup steel ribs on main rib joints are treated, a mechanical connecting joint reinforcing steel bars and the stirrups are bound, and the action of the stirrups on an inclined column structure is not weakened.

Description

technical field [0001] The invention relates to a construction technique in road and bridge construction, in particular to a construction method for a large-section concrete Y-shaped column. Background technique [0002] Since the beginning of this century, the large-section concrete slanted column structure system has developed rapidly in road and bridge construction, and has become the most used structural system in road and bridge construction. The large-section concrete slanted column structure system is that the main reinforcement of the slanted column is equipped with stirrups. After pouring concrete, the main reinforcement of the slanted column, the stirrups and the concrete become a composite structural member that works together. [0003] The existence of the steel bone greatly improves the ductility of the component, making it have strong deformation capacity, good seismic performance, and high bearing capacity, while the concrete structure has better fire resistan...

AI Technical Summary

Problems solved by technology

The steel structural components of large-section concrete Y-shaped columns mainly include slanted column formwork and slanted column support system. The installation, assembly and construction of the slanted column support system are complicated. In addition, the Y-shaped column is heavy and the component cross-section is huge. It is an artistic and special-shaped building. Whether it is Understand the design requirements of architectural designers, or follow-up construction is very difficult

In short, the installation and positioning accuracy of Y-shaped space modeling is high, and the processing of bending and torsion components is difficult. At present, developed countries such as Japan and the United States are limited to the production of elevated and similar small Y-shaped columns. The traditional production process cannot break through the production Difficulties in construction of large Y-shaped columns

[0004] Aiming at the difficulties of complex construction and complex forming in the construction of large-section concrete slanted columns in the existing construction technology, the present invention provides a construction method of large-section concrete Y-shaped columns different from the prior art
