Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0023] In order to overcome the deficiencies of the prior art, the present invention applies the large-size shape memory alloy component to the steel pipe column-H-shaped beam in the steel frame structure in consideration of the ductility, energy consumption and rigidity requirements of the circular tubular column-H-shaped beam joint connection, forming a circular tube column-H-shaped beam connection node with self-recovery and energy dissipation capabilities, figure 1 shown in its front view, figure 2 It is shown in top view.

[0024] The steel pipe column-H-beam joint containing shape memory alloy bolts in the present invention includes column end components, beam end components, column connection end plates 7, beam connection end plates 8 and shape memory alloy bolts. Among them, the column end assembly is an assembly that includes the pi...

Abstract

The invention discloses a steel pipe column-H-shaped beam joint adopting shape memory alloy bolts, which belongs to the technical field of building engineering. The steel pipe column-H-shaped beam joint comprises a column end assembly, a beam end assembly, a column connecting end plate, a beam connecting end plate and the shape memory alloy bolts, wherein the column end assembly is a connecting assembly comprising a pipe column and is connected with the column connecting end plate; the beam end assembly is a connecting assembly comprising an H-shaped beam and is connected with the beam connecting end plate; and the column connecting end plate is connected with the beam connecting end plate through the shape memory alloy bolts. The steel pipe column-H-shaped beam joint disclosed by the invention has self recovery ability and can return back to the original position after external load is discharged; and in addition, the welding work of the pipe column and an outer annular plate, the outer annular plate and the column connecting end plate as well as the H-shaped beam and the beam connecting end plate of the steel pipe column-H-shaped beam joint, the screw hole opening work of the beam connecting end plate and the column connecting plate and the like can be directly completed in a factory, the connection can be carried out by using bolts on site, and thus the installing and the repairing of the steel pipe column-H-shaped beam joint are very convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a steel pipe column-H-beam joint, in particular to a steel frame structure and a steel pipe concrete frame structure suitable for high seismic self-recovery performance requirements. Background technique [0002] In recent years, the superelastic properties of shape memory alloy materials have been paid attention to by researchers. Some scholars at home and abroad have realized the self-recovery of nodes by designing an H-shaped beam-H-shaped column node with a shape memory alloy screw. However, the research on circular tubular column-H-shaped steel beam joints with shape memory alloy bolts is still blank. In the aforementioned H-beam-H-column joints with shape memory alloy screws, the slenderness ratio of the screws is relatively large, and the problem of easy buckling under pressure has not been effectively solved, thus limiting its application in engineering; an...
