Problems solved by technology

[0007] In order to solve the problem that the existing support mainly relies on the deformation of the inner core to consume energy, the inner core may lose its function prematurely in the earthquake, and the inner core may become unstable 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:

Abstract

The invention relates to an instability preventing device, belongs to the field of damping of buildings, and is used for solving the problems that an existing support mainly depends on deformation ofan inner core to consume energy, thus, the inner core is out of action too early in earthquake, the changing and maintaining costs are high, and the inner core does not have self-reduction ability. According to the technical scheme, a first torsion instability preventing device is mounted in space between the end, which is connected to the inside of a restraining outer sleeve in a covering manner,of an energy-dissipation inner core along the axis direction thereof and the inner wall, which corresponds to the end, of the restraining outer sleeve; and a second torsion instability preventing device is mounted in space between the other end of the energy-dissipation inner core and the inner wall, which corresponds to the end, of the restraining outer sleeve.

Description

[0001] This application is a divisional application with application number 2017103489988, application date 2017-05-17, and invention name "buckling-resistant support with double torsional instability-preventing devices". technical field [0002] The invention belongs to the field of building shock absorption, and relates to a buckling-proof support with double torsion anti-destabilization devices. Background technique [0003] Traditional civil engineering structural supports mainly include: central support, eccentric support, energy-dissipating corner support, energy-dissipating frame support and other support forms. Most supports mainly consume seismic energy through deformation to reduce earthquake disasters. 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 safety of buildings. [0004] Energy dissipat...
