Inner sleeve type concrete-filled steel tube beam column joint and production method thereof

Abstract

The invention discloses an inner sleeve type concrete-filled steel tube beam column joint, and belongs to the field of construction steel structures. The inner sleeve type concrete-filled steel tube beam column joint is mainly used for a connecting joint of a concrete-filled steel tube and a steel beam. The inner sleeve type concrete-filled steel tube beam column joint comprises a steel tube column, and an inner sleeve embedded in the steel tube column, wherein the upper edge peripheries in the abutment positions of the inner sleeve and the steel tube column are welded together; and the inner sleeve and the steel tube column are welded together at the upper and lower sides of a welding line between the steel tube column and a steel beam flange, so that the inner sleeve and the steel tube column are connected as a whole. The inner sleeve type concrete-filled steel tube beam column joint not only can guarantee the reinforcement of the steel tube column in the joint, but also can realize vertical penetration of the joint of the steel tube column, and has no shield when concrete is filled in the steel tube column, so that the compactness of the concrete in the steel tube column is guaranteed.

Description

Technical field [0001] The invention relates to an inner sleeve type steel tube concrete beam-column node, which belongs to the field of building steel structures. Mainly used for the connection node of steel tube concrete and steel beam. Background technique [0002] At present, the joints between the concrete-filled steel tube columns and the steel beams in the steel structure of buildings generally adopt internal diaphragm beam-column nodes [1] , In order to strengthen the joints, a horizontal steel plate with openings is usually added at the flange of the steel beam corresponding to the steel pipe column as the inner diaphragm, and the inner diaphragm is welded to the periphery of the steel pipe column. However, for this kind of internal diaphragm type beam-column connection node, the box-section column pipe wall is welded on both sides of the inner and outer sides at the same position, which will cause the column wall to become brittle, and the column wall may produce lamina...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the traditional internal partition beam-column joints, such as the tube wall becomes brittle, the column wall may have layered tearing, the fabrication is difficult, and the concrete at the lower corner of the connection between the internal partition and the steel tube column is not dense, etc., the present invention provides a Inner Sleeve Concrete Steel Tube Beam-Column Joints
