Buckling-resistant support

Abstract

The invention provides a buckling-resistant support and belongs to the field of building shock-absorption. The buckling-resistant support is used for solving the problems that an existing buckling-resistant support mainly depends on energy consumption of deformation of an inner core to result in that the inner core is out of action too early in an earthquake, changing and maintaining costs are high, and a self-resetting ability is not possessed. The buckling-resistant support is characterized in that a reversing anti-destabilization device is installed in the space between a part, covered with a constraining outer sleeve, of the energy-consuming inner core and the inner wall, corresponding to the part, of the constraining outer sleeve. The effects are that the axial loads borne by the energy-consuming inner core are dispersed to a spring reversing plane through the installation of the reversing anti-destabilization device, so that energy-consumption burden of the energy-consuming inner core is greatly reduced, the possibility of destabilization of the inner core is lowered, the changing frequency of the inner core is decreased, and maintaining cost is reduced.

Description

technical field [0001] The invention belongs to the field of building shock absorption and relates to an anti-buckling support. Background technique [0002] Traditional civil engineering structural supports mainly include: eccentric support, energy-dissipating corner brace, energy-dissipating frame support and other support forms. Most supports mainly dissipate seismic energy through deformation to reduce the effect of earthquakes. Due to the elastic-plastic properties of structural components, these energy-dissipating supports will inevitably undergo some damage and deformation, which is not conducive to energy dissipation and has an impact on the stability of the building. [0003] The energy-dissipating and shock-absorbing technology is mainly: by adding passive energy-dissipating devices to the original structure, the seismic energy originally consumed by the structural components is consumed, and the deformation and damage caused by the vibration to the structure are g...

Problems solved by technology

[0006] In order to solve the problem that the existing anti-buckling brace mainly relies on the deformation and energy consumption of the inner core, the inner core may lose its function prematurely in the earthquake, and the inner core may lose its stability due to external constraints, and the cost of replacement and maintenance is high. To solve the problem of resetting ability, the present invention proposes the following technical solutions:
