Self-resetting buckling-resistant support

Abstract

Provided is a self-resetting buckling-resistant support. The self-resetting buckling-resistant support belongs to the field of building shock-absorption, and is used for solving the problem that an existing support doesn't have a self-resetting ability. The technical key points are that two steel plates with racks are symmetrically fixed to two side surfaces of the steel plates respectively, gears meshing with the racks are arranged between the steel plates with the racks and the inner wall of a constraining outer sleeve which corresponds to and is parallel to the steel plates, and both the upper and the lower sides of each gear are directly fixed to two vortex springs limited on the parallel inner wall; and the gears and the vortex springs are fixed between the steel plates with the racks and the inner wall of the constraining outer sleeve which corresponds to and is parallel to the steel plates by a supporting frame extending out of the parallel inner wall. The effect is that energy-consumption inner core axial loading bearing is dispersed into spring vortex plane bearing.

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 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
