Prefabricated self-restoring circular steel pipe concrete composite node

Abstract

The invention relates to the technical field of building structural components, and discloses an assembled self-restoring circular steel pipe concrete composite node, which includes a circular steel pipe column and an H-shaped steel beam. The steel bar runs through the circular steel pipe column. The central splicing column and the lower steel pipe column, the upper steel pipe column and the central splicing column are connected through the upper sleeve connector, and the central splicing column and the lower steel pipe column are connected through the lower sleeve connector; the H-shaped steel beam passes through The upper and lower sleeve connectors are connected with the round steel column. All the components in the present invention can be processed in the factory, and all the parts are connected by bolts on site, which realizes complete assembly construction, can avoid quality problems that may be caused by on-site welding, speed up the construction progress, and improve labor productivity; The goal of anti-seismic fortification is to ensure that it is not damaged by small earthquakes, quickly recovers from deformation after moderate earthquakes, and can be accurately disassembled and quickly replaced after major earthquakes.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to an assembled self-restoring circular steel pipe concrete composite node. Background technique [0002] Steel structural components form a structural system by connecting nodes, and the choice of node form has a direct impact on structural integrity, reliability, construction period, and the design and construction of auxiliary components. The connection between beam and column of frame structure can be divided into rigid connection, flexible connection and semi-rigid connection according to the difference of rotational stiffness. [0003] At present, rigid connection design is the most widely used. Traditional frame beam-column rigid connection can be divided into three types: fully welded connection, bolt-weld hybrid connection and bolt connection. The study found that the first two connection forms are prone to brittle failure due to the quality of the b...

Problems solved by technology

However, the self-resetting between columns needs to be researched and developed for using high-strength steel reinforced steel tube concrete composite joints between columns.
