Prefabricated reinforced concrete column connection structure and method

Abstract

The invention relates to a prefabricated reinforced concrete column connection structure and method. The idea of equivalent cast-in-place is adopted, based on mechanical optimization analysis, a method connecting to the middle of a column is proposed, shape steel in the column is connected by a shape steel sleeve instead of welding and bolt connection commonly used in engineering, and the construction is simplified; rebars in the column are connected by a mechanical sleeve instead of a grouting sleeve often used in the assembled reinforced concrete structure, and the cost is reduced; the connection part is covered with a steel plate tube and no stirrups are arranged, and the construction is simplified; a hole is reserved in a prefabricated reinforced concrete column at the upper part of the connection part; and after installation of the steel plate tube is completed, high-performance engineering cement-based composite materials (ECC) can be poured to further ensure the integral strength and deformation capacity of the connection part. The prefabricated reinforced concrete column connection structure has high assembly property, the assembly mode is basically a bolt connection with convenient construction, on-site welding and large-area concrete pouring operation are avoided, and the construction is convenient. At the same time, the prefabricated reinforced concrete column connection structure and method is based on the idea of equivalent cast-in-place, and the strength and deformation capability of the connection part can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a connection structure and method between prefabricated steel concrete columns. Background technique [0002] Steel-concrete structure (SRC) refers to the steel-concrete composite structure formed by disposing steel in the section of ordinary reinforced concrete members. Steel concrete structure has the advantages of both concrete structure and steel structure, and has significant performance advantages. It is a type of high-rise building structure that is very suitable for earthquake resistance, fire resistance and wind resistance. [0003] Although the steel concrete structure has obvious performance advantages in terms of mechanical performance, the obvious disadvantages of the steel concrete structure, such as numerous procedures and complex construction, have severely restricted the popularization and application of the steel concrete structure in practical ...
