Embodiment Construction

[0032] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0033] In order to overcome the deficiencies of the prior art, the present invention takes into account the requirements of the assembled steel frame for various disaster defenses such as earthquake disasters and continuous collapses, and applies large-size shape memory alloy components combined with unilateral bolt technology to square steel pipes in steel frame structures The connection between the column and the H-shaped steel beam, and reinforcement measures are taken at the end of the beam to form a square steel pipe column-H-shaped steel beam connection node that can comprehensively prevent earthquake disasters and continuous collapse of the structure. figure 1 shown in its front view, figure 2 It is shown in top view.

[0034] In the present invention, the square steel pipe column-H-shaped steel beam joint capable of comprehensively pr...

Abstract

A reinforcing method and reinforcing device of steel pipe column-H-shaped beam for resisting continuous collapse belongs to the technical field of building engineering. The device comprises a beam lower wing edge reinforcing plate, a baffle reinforcing plate, a cover plate and a connecting bolt. According to the method, on the basis that a connection mode of full welding connection or wing edge welding and web bolt connection of the beam is used and the column is connected with the baffle, the beam lower wing edge and the lower baffle are reinforced by welding reinforcing plates on the two sides of the connecting area, the beam lower wing edge and the lower baffle are again connected with a cover plate through bolts for reinforcement. According to the invention, by reinforcing the node ofthe beam and column of a steel frame, the vertical bearing capacity of the node sub-structure after the failure of the lower column of the node can be improved, the performance of continuous collapseresistance of the structure is obviously improved, the connecting node can be used for the reinforcement and reconstruction of important buildings.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a square steel pipe column-H-shaped steel beam joint of an assembled steel frame structure, and is especially suitable for a recoverable functional frame structure capable of comprehensively preventing earthquakes and continuous collapse. Background technique [0002] The multi-hazard defense of engineering structures has become an important research frontier of international civil engineering in recent years. The prefabricated steel frame structure has a fast construction speed, is green and environmentally friendly, and has a wide range of application prospects. However, the inherent "thin arms and thin legs" characteristics of steel frame structures make them prone to earthquake collapse or continuous collapse after local damage caused by accidents. Therefore, how to improve the anti-seismic and progressive collapse capabilities of prefabricated steel frame str...
