Steel pipe concrete column H-shaped steel beam fabricated rigid joint strong beam strong column structure and construction method

Abstract

The invention discloses a steel pipe concrete column H-shaped steel beam fabricated rigid joint strong beam strong column structure and a construction method. The steel pipe concrete column H-shaped steel beam fabricated rigid joint strong beam strong column structure comprises steel plate components, wherein the steel plate components are arranged at column beam joints and are welded to steel pipes of steel pipe concrete columns, joint components are welded to the connecting surfaces of the steel plate components and H-shaped steel beams, the joint components comprise upper part strutting pieces, lower part strutting pieces and web connecting pieces, the web connecting pieces are arranged between the upper part strutting pieces and the lower part strutting pieces, gaps matched with the flange thickness of the H-shaped steel beams are formed between the web connecting pieces and the upper part strutting pieces and between the web connecting pieces and the lower part strutting pieces, high-strength bolt holes corresponding to the H-shaped steel beams are formed in the flanges of the opposite faces of the upper part strutting pieces and the lower part strutting pieces, and the high-strength bolt holes corresponding to the H-shaped steel beams are formed in the web connecting pieces. According to the steel pipe concrete column H-shaped steel beam fabricated rigid joint strong beamstrong column structure and the construction method thereof, two-way split stirrups are utilized, so that the defects of insufficient constraint effect and buckling of steel pipes are overcome, strutting pieces are arranged at the beam column joints, so that the bearing capacity of the hogging moment area of beam ends can be effectively improved, and the whole joints are definite in force transmission and good in overall performance.

Description

technical field [0001] The invention belongs to the field of construction engineering structures, and relates to a steel pipe concrete column H-shaped steel beam assembly type rigid joint joint strong beam strong column structure and a construction method. Background technique [0002] The concrete structure has better integrity, durability and fire resistance, but poor bending and shear resistance, and is prone to brittle failure; the steel structure has high material strength, light weight, good plastic toughness, and poor fire resistance and corrosion resistance. The concrete-filled steel tube structure is evolved and developed on the basis of steel-shaped concrete structure, spiral-reinforced reinforced concrete structure and steel structure. Concrete-filled steel tube can take advantage of the advantages of both concrete and steel structures at the same time, and the interaction between the two can overcome the two The shortcomings of the material itself. Concrete fill...

AI Technical Summary

Problems solved by technology

A ring-shaped reinforced concrete beam is poured around the steel pipe column to transmit bending moment and shear force. The advantage is that it has no direction, that is, it can be connected with the floor in any direction. The disadvantage is that the rigidity is small
