An anti-buckling shock-absorbing support hanger

Abstract

An anti-buckling shock-absorbing support and hanger is composed of a load-bearing boom, a load-bearing beam, a shock-absorbing support, a connecting piece, an anchor piece and a pipe fixing piece. The load-bearing boom and the load-bearing beam are connected by bolts, the connecting piece is clamped into the load-bearing beam and fixed with bolts, one end of the shock-absorbing support and the connecting piece are connected by a pin, and then the other end of the shock-absorbing support and the anchor are connected by a pin, and the The pipe connector is connected and fixed with the load-bearing beam. The damage mode of the traditional shock-absorbing support and hanger can be controlled and improved, so that the damage of the shock-absorbing support and hanger is mainly concentrated in the shock-absorbing unit of the shock-absorbing support, so as to avoid the early damage of the connecting piece leading to the overall failure of the shock-absorbing support and hanger; The reasonable opening of the shock-absorbing support core unit gives full play to the material strength performance of the shock-absorbing support, and the synchronous yielding energy consumption of the shock-absorbing unit core in the shock-absorbing support gives full play to the hysteretic characteristics of the material; and the shock-absorbing unit of the shock-absorbing support is in the It is easy to replace after damage, saves costs, and improves the material use efficiency of the shock-absorbing support and hanger.

Description

technical field [0001] The invention belongs to the field of vibration control of civil engineering, and in particular relates to an anti-buckling type shock-absorbing support hanger used for suspension type non-structural components such as cable bridges. Background technique [0002] Article 3.7.1 of my country's GB 50011-2010 Code for Seismic Design of Buildings stipulates that the mechanical and electrical equipment attached to the building itself and its connection with the main structure should be designed for earthquake resistance. The anti-seismic support and hanger evolved from the gravity support and hanger. As the most important seismic component of the suspended non-structural components, its main function is to constrain the response of the suspended non-structural components under the action of earthquakes and ensure the suspension of the non-structural components. The normal work of the component. The anti-seismic support hanger is mainly composed of load-bea...

AI Technical Summary

Problems solved by technology

[0004] 1) It is difficult to give full play to the material strength of the seismic support

The component size of the seismic brace is mainly controlled by the slenderness ratio, and the section strength is much lower than the material strength, which makes it difficult to fully exert the material strength performance of the seismic brace;

[0005] 2) Suspended non-structural components are damaged due to damage to seismic connectors

The earthquake damage investigation and experimental research found that the connectors of the seismic support hangers are the weak parts of the earthquake resistance, and the damage of the connectors will easily lead to the loss of effective support of the suspended non-structural components and damage them;

[0006] 3) Difficult to replace damaged components

Due to the relatively weak connection between the anti-seismic support and other components of the traditional anti-seismic support and hanger, the damage of the anti-seismic support and hanger is mainly concentrated on the connecting parts and the two ends of the anti-seismic support. As a result, the seismic support and hanger usually needs to be replaced as a whole and the seismic support The main body of the
