A kind of structure and construction method of steel pipe concrete column h-shaped steel beam assembly type rigid joint strong beam strong column

Abstract

A steel tube concrete column H-shaped steel beam assembly type rigid joint joint strong beam strong column structure and construction method, including a steel plate member arranged at the node of the column beam and welded to the steel pipe of the steel tube concrete column, the connecting surface of the steel plate member and the H-shaped steel beam Node components are welded on the top, and the node components include upper supports, lower supports and web connectors, the web connectors are arranged between the upper supports and the lower supports, and the web connectors are connected with the upper supports and the lower supports There is a gap between the parts that matches the thickness of the flange of the H-shaped steel beam. High-strength bolt holes corresponding to the H-shaped steel beam are provided on the flanges of the upper support and the lower support. High-strength bolt holes corresponding to H-shaped steel beams. The present invention uses two-way opposite tension stirrups to make up for the lack of restraint effect of the steel pipe and the defects of buckling, and the supports are arranged at the beam-column joints, which can effectively improve the bearing capacity of the negative bending moment area at the beam end, the force transmission of the entire joint is clear, and the overall performance it is good.

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
