Dismountable assembly type circular steel tube concrete column

Abstract

The invention provides a dismountable assembly type circular steel tube concrete column. The dismountable assembly type circular steel tube concrete column mainly comprises an upper circular steel tube concrete column, a lower circular steel tube concrete column, a column flange connecting piece, two semicircular steel plates with holes and a pulling-resistant connecting pair. Structural measures of the circular steel tube concrete columns and the column flange connecting piece are reasonably designed, the pulling-resistant connecting pair is adopted for splicing the circular steel tube concrete columns, then grouting is carried out from the reserved semicircular holes of the semicircular steel plates, and finally, the dismountable fabricated circular steel tube concrete column is formed. When the circular steel tube concrete columns are replaced, a bolt bar is dismounted, so that the circular steel tube concrete columns and the column flange connecting piece are taken down, and further removal and replacement of the circular steel tube concrete columns are realized. The dismountable assembly type circular steel tube concrete column has the advantages that all the components are connected in a field assembly manner, building industrialization assembling efficiency is improved, dismounting, separating and replacing functions of an assembly type combined structure column-column component are realized, and a novel energy-saving and environment-friendly architectural concept that a building component can be dismounted and altered is shown.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and is specifically applicable to the field of on-site splicing operation between circular steel pipe concrete columns and columns in a multi-high-rise assembled steel-concrete composite structure. Background technique [0002] In order to promote the industrialization of construction, the "Technical Regulations for Prefabricated Concrete Structures" has been promulgated, and prefabricated concrete structures have been widely promoted in engineering practice, but this regulation still does not solve the problem of many wet operations on site and long concrete curing time. question. At present, there is a lack of systematic research on the design method of the key connection parts of the prefabricated building structure system.

At present, there is a lack of systematic research on the design method of the key connection parts of the prefabricated building structure system

On the other hand, due to its shortcomings such as serious environmental pollution, high material and energy consumption, and low recycling rate of building materials, the traditional reinforced concrete structure does not meet the "applicable, economical, green, and beautiful" construction policy promoted by the state.
