Assembled TRC-steel pipe composite confined concrete column and installation method thereof

Abstract

The invention discloses an assembled TRC-steel pipe composite confined concrete column and an installation method thereof. The assembled TRC-steel pipe composite confined concrete column structurally comprises concrete column sections and a connecting bottom plate assembly, wherein the connecting bottom plate assembly is matched with the upper concrete column section and the lower concrete column section and is tightly connected with the upper concrete column section and the lower concrete column section, and the assembly of prefabricated columns is achieved; each concrete column section consists of a TRC shell, a constraint steel pipe and core concrete; semi-closed grouting sleeve connecting pieces are arranged on the periphery of the connecting end of each constraint steel pipe; a connecting bottom assembly mainly consists of a steel plate, a small-diameter opening sleeve and a strip connecting steel bar; and when the upper column section and the lower column section are connected through the steel plate assembly, the small-diameter opening sleeve is connected with the semi-closed grouting sleeve connecting piece in a sleeved mode, and the steel plate is connected with the steel pipe in a sleeved mode. Factory prefabrication and on-site rapid positioning installation are achieved, on-site pouring is not needed, and the curing process is not needed. The advantages of high construction speed, corrosion resistance, high practicability, reliable connection and the like are achieved, and the problems that a traditional assembled concrete column joint has poor connection quality, and the construction environment cannot be guaranteed are solved.

Description

technical field [0001] The invention relates to a method for preparing and connecting an assembled TRC (Textile Reinforce Concrete)-steel tube composite confined concrete column. Background technique [0002] Compared with the traditional cast-in-place reinforced concrete structure, the prefabricated structure has the advantages of modularization of architectural design, convenience of installation and construction process, improvement of construction site environment and labor conditions, resource saving and construction cost reduction, sustainability and A series of advantages such as increased efficiency. In order to further promote the healthy and rapid development of prefabricated buildings in my country, it is necessary to conduct more detailed research on prefabricated buildings in China. [0003] However, in the tidal zone of seawater, traditional fabricated steel pipe concrete columns are corroded by chloride salts, and are prone to corrosion of steel bars and dete...

AI Technical Summary

Problems solved by technology

The above two inventions improve the connection performance by adding rigid components in the sleeve, but at the same time, the increase is complicated, the cost is high, the hoisting and positioning are difficult, and the corrosion resistance has not been improved, so there are great limitations in practical applications. sex
