Anti-buckling support and installation method of multi-stage energy dissipation foam metal sphere composite inner plate

Abstract

The invention discloses an anti-buckling support and installation method of a multi-stage energy dissipation foam metal sphere composite inner plate. A multi-stage energy dissipation foam and metal sphere composite inner plate comprises a composite energy dissipation restraint rod body 1 and a hinged shoe 2, wherein the hinge shoe 2 comprises a bottom plate and an ear plate; installation holes areformed in the periphery of the bottom plate and are connected through high-strength bolts and end-column reserve anchor part bolt holes in a bolted mode; a hole opening is formed in the middle of theear plate, and the diameter of the hole opening is the same as the diameter of a high strength bolt pin 3; rod arms of loading connection rods 5 at the two ends of the hinge shoe 2 and the compositeenergy dissipation restraint rod body 1 are connected through the high strength bolt pin 3; the composite energy dissipation restraint rod body 1 comprises a restraint steel sleeve 4, a sealing rubberring 10, and a sleeve cover plate 11; and the resistant steel sleeve 4 is a rectangular steel sleeve, a groove channel in the sleeve is provided with the loading connection rods 5, a foam metal sphere 6, a memory alloy spring 7, a high-damping curved-surface rubber 8, and an arc tensile steel plate 9. The multi-stage energy dissipation foam metal sphere composite inner plate can be widely used inthe technical fields of building structures, bridges, non-structural components and the like, and has the characteristics of environmental protection, uniform distribution of energy dissipation, multi-stage energy dissipation, and strong self-recovery ability.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to a multi-stage energy-consuming foam metal ball composite inner plate anti-buckling support and an installation method, and belongs to the technical field of shock absorbing devices. Background technique [0002] Among the provincial capitals of my country's 34 administrative regions, at least 21 cities have active faults and potential dangers of near-field strong earthquakes; more than 2,000 cities and towns across the country are constantly facing the threat of catastrophic earthquakes. The demand for safety due to rapid economic development and the threat of severe earthquake disasters faced by the vast cities in our country have produced a clear contradiction, especially the recent earthquakes in my country, the Wenchuan earthquake, the Yushu earthquake, and the Ludian earthquake have caused huge casualties and Property damage exacerbates this conflict.

AI Technical Summary

Problems solved by technology

[0006] At present, the most widely used in engineering is the traditional anti-buckling support represented by the full-section yield energy consumption of concrete filling and soft steel core. It mainly relies on stretching or compressing the inner soft steel core to absorb earthquake energy, and it cannot be multi-stage-multi-stage. It consumes energy, does not have the ability to restore deformation, cannot be repaired, and belongs to one-time use, which does not conform to the green building development concept of environmental protection and sustainability

In addition, the traditional mild steel anti-buckling support has a large self-weight, which is easy to generate a large excess load on the building structure, which is not conducive to the widespread use of the same building

In order to solve the problem that the anti-buckling support in the past is easy to cause environmental pollution, has a large self-weight, a single energy consumption form, and cannot multi-stage energy consumption, the present invention provides a multi-stage energy-dissipating foam metal ball composite inner plate anti-buckling support
