Concrete column high-seismic-resistance fabricated connecting structure

Abstract

The invention discloses a concrete column high-seismic-resistance fabricated connecting structure which comprises an upper segment and a lower segment. The upper segment and the lower segment are sleeved with each other through sleeves and fixedly connected through a flange structure. By adopting the structures of convex-convex pluggable connection, sleeving of the sleeves and flange connection, joint faces, which are connected, of an upper body and a lower body are located at three portions along the height of a column, the phenomenon that weak joint portions are concentrated on the same section is avoided, a bridge pier can bear changeable loads such as pressure, shearing force and bending moment, the good seismic resistance is achieved, and therefore the concrete column high-seismic-resistance fabricated connecting structure is applicable to the bridge pier, in particular to large bridges. Meanwhile, construction can be performed by adopting a factory prefabrication on-site assembling mode, the construction period can be greatly shortened, the construction cost can be lowered, and due to the assembling mode, the whole bridge pier has the good adaptability for diversified loads.The service life of the bridge pier is prolonged, and the remarkable technical and economic comprehensive benefits are achieved.

Description

Technical field [0001] The invention belongs to the field of building structure and bridge engineering, and particularly relates to an assembled connection structure of concrete columns with high seismic performance. Background technique [0002] Factory-based prefabricated component segments are assembled on site to form an overall structure, which is an inevitable development trend of today's civil engineering structure. [0003] Column is the main load-bearing structure indispensable for building structure. Its function is to transfer the superstructure load to the foundation. The reinforced concrete column formed by the on-site pouring construction usually has sufficient bearing capacity and good seismic performance, so the existing building The columns in the structure, especially the bridge piers, are basically cast-in-place reinforced concrete columns. [0004] However, there are three major problems with cast-in-place reinforced concrete columns: First, the on-site construct...

AI Technical Summary

Problems solved by technology

[0006] To sum up, there are two major defects in the connection structure of the existing prefabricated concrete columns: one is that the upper and lower prefabricated segmental columns must be connected by cast-in-place or pouring; the role of
