Buckling-restrained damping support hanger

Abstract

A buckling-restrained damping support hanger is composed of a load-bearing hanger rod, a load-bearing cross beam, a damping support, a connecting piece, an anchoring piece and a pipeline fixing piece. The load-bearing hanger rod is connected with the load-bearing cross beam through a bolt, the connecting piece is clamped into the load-bearing cross beam and fixed through a bolt, one end of the damping support is connected with the connecting piece through the pin shaft, then the other end of the damping support is connected with the anchoring piece through the pin shaft, and the pipeline connecting piece is fixedly connected with the load-bearing cross beam. The damage mode of a traditional damping support hanger can be controlled and improved, so that the damage of the damping support hanger is mainly concentrated on a damping unit of a damping support, and the overall failure of the damping support hanger caused by advanced damage of a connecting piece is avoided; through reasonable trepanning of the core unit of the damping support, the material strength performance of the damping support is brought into full play, and the hysteretic characteristic of the material is brought into full play through synchronous yield energy consumption of the core of the damping unit in the damping support; and the damping units of the damping support are convenient to replace after being damaged, the cost is saved, and the material use efficiency of the damping support hanger is improved.

Description

technical field [0001] The invention belongs to the field of vibration control of civil engineering, and in particular relates to an anti-buckling shock-absorbing support and hanger used for suspension type non-structural components such as cable bridges. [0002] technical background [0003] Article 3.7.1 of my country's GB 50011-2010 "Code for Seismic Design of Buildings" stipulates that the auxiliary mechanical and electrical equipment of the building itself and its connection with the main structure should be designed for seismic resistance. The anti-seismic support and hanger is evolved from the gravity support and hanger. As the most important anti-seismic component of the suspended non-structural component, its main function is to restrain the response of the suspended non-structural component under earthquake action and ensure the suspension of the non-structural component. normal functioning of the components. The anti-seismic support and hanger is mainly composed ...

AI Technical Summary

Problems solved by technology

[0005] 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;

[0006] 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;

[0007] 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
