Torsion anti-destabilization device of buckling-restrained brace

Abstract

The invention discloses a torsion anti-destabilization device of a buckling-restrained brace, and belongs to the field of building vibration reducing. The torsion anti-destabilization device of the buckling-restrained brace is used for solving the problems that an existing buckling-restrained brace mainly depends on inner core deformation energy consumption resulting in the situation that an innercore is out of action untimely in an earthquake, the replacement and maintenance costs are high, and the self-reset capacity is not achieved. According to the technical main points, the torsion anti-destabilization device is characterized in that the torsion anti-destabilization device comprises torsion springs, limiting clamps and a guiding iron bar, the guiding iron bar penetrates through the energy consumption inner core in the direction perpendicular to the axial direction of the energy consumption inner core and is fixed to the energy consumption inner core, an iron core is exposed on the two sides of the interior of a space, and the torsion springs are connected to the iron core in a covering mode; spring force arms connected with torsion spring bodies are limited by the limiting clamps on the upper side and the lower side of a torsion plane formed when the torsion springs twist, and the torsion anti-destabilization device has the effects that the torsion anti-destabilization device is mounted, and axial load of the energy consumption inner core is borne and dispersed on the spring torsion plane to be borne, so that energy consumption load of the energy consumption inner core is greatly reduced, and the possibility of destabilization of the inner core is reduced, thus the replacing frequency of the inner core is reduced, and the maintenance cost is reduced.

Description

[0001] This application is a divisional application of application number 2017103486231, application date 2017-05-17, and invention name "buckling-resistant support". technical field [0002] The invention belongs to the field of building shock absorption and relates to an anti-buckling support. Background technique [0003] 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. [0004] The energy-dissipating and shock-absorbing technology is mainly: by adding passive energy-dissipating devices to the original ...

Problems solved by technology

[0007] In order to solve the problem that the existing anti-buckling support 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:
