Self-resetting device of self-resetting buckling-restrained support

Abstract

The invention provides a self-resetting device of a self-resetting buckling-restrained support, belongs to the field of shock absorption of buildings, and is used for solving the problem that an existing support does not have self-resetting ability. According to the technical scheme, two steel plates with racks are separately symmetrically fixed on two side surfaces of a steel plate, a gear whichis engaged with the corresponding rack is mounted between each steel plate with the rack and the inner wall of a restraining outer sleeve which is opposite and parallel to the steel plate with the rack; two vortex springs which are limited on the parallel inner walls are directly fixed on the upper side and the lower side of each gear; each gear and the corresponding vortex springs are fixed between the corresponding steel plate with the rack and the inner wall of the restraining outer sleeve which is opposite and parallel to the steel plate by a support frame which extends from the parallel inner walls. The self-resetting device of the self-resetting buckling-restrained support has the effects that axial load of an energy-dissipation inner core is born and dispersed to vortex planes of the springs.

Description

[0001] This application is a divisional application with application number 201710348602X, application date 2017-05-17, and invention name "self-resetting 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...

Problems solved by technology

[0007] In order to solve the problems that the existing support mainly relies on the deformation and energy consumption of the inner core, which may cause the inner core to lose its function prematurely in an earthquake, the cost of replacement and maintenance is high, it does not have self-resetting ability, and it is not sensitive to small vibration supports, the present invention proposes the following Technical solution: A self-resetting anti-buckling support, including an energy-dissipating inner core, a steel plate connected to the end of the energy-dissipating inner core in the axial direction, a steel plate with a rack, and a restraining outer sleeve; the restraining outer sleeve The cover is connected to the outer periphery of the energy dissipation inner core and the steel plate. The constraining outer sleeve has a set of opposite and parallel parallel inner walls. The energy dissipation inner core is parallel to it. Two steel plates with racks are symmetrically fixed on the steel plates On the two sides, a gear meshing with the rack is installed between the steel plate with a rack and the inner wall of the opposite and parallel constraining outer sleeve, and two constrained pins are directly fixed on the upper and lower sides of the gear. The vortex spring located on the parallel inner wall, the gear and the vortex spring are fixed between the steel plate with the rack and the inner wall of the opposite and parallel constraining outer sleeve by the support frame protruding from the parallel inner wall between
