Wave-shaped cable hyperelastic self-resetting shock absorption support

Abstract

The invention relates to a wave-shaped cable hyperelastic self-resetting shock absorption support which comprises a support body, an inhaul cable, a resetting device, an anchoring device and the like.The support body provides vertical bearing capacity and rotating capacity for the wave-shaped cable hyperelastic self-resetting shock absorption support and comprises an upper seat plate and a lowerseat plate. Wherein the upper seat plate and the lower seat plate are connected through an inhaul cable, a plurality of channels are formed in the upper seat plate, the inhaul cable penetrates throughthe channels to be connected with an anchoring device fixed to the lower seat plate, a buffer spring is arranged in the anchoring device, and the inhaul cable support body elastically stretches, stretches and resets. The inhaul cable in the channel is provided with the waveform section with a certain length, the reset devices are arranged on the two sides of the waveform section inhaul cable, when the support moves, the waveform section inhaul cable has large deformation capacity, and the reset devices provide hyperelastic reset force for the support through the inhaul cable. According to theshock absorption support, the large displacement requirement of the shock absorption support is met, buffering, limiting and resetting force is provided for the support within the limited support space range, and the shock absorption support has good self-resetting, buffering, energy dissipation and limiting performance.

Description

technical field [0001] The application belongs to the fields of civil engineering and anti-seismic, and in particular relates to a corrugated cable damping spring mechanism. Background technique [0002] In engineering technology, bearings are very important supporting components, especially in bridge engineering, bearings are widely used between upper and lower structures. In high-intensity earthquake areas, the use of bearings for seismic isolation design is an important means to ensure the seismic performance of structures. Seismic damage investigations and related studies have shown that in order to control the residual displacement of structures after earthquakes, improve the recoverability of structures, and reduce earthquake disasters Due to the social and economic impacts, the shock-absorbing and isolating bearing should have large displacement adaptability, self-resetting ability, energy consumption buffering ability and good limit ability. [0003] However, there ...

Problems solved by technology

For the scheme of increasing the size of the spring, due to the limitation of the support installation space, it is not practical and the project cost is high; for the scheme of reserving the initial gap, the support has the problem of lack of self-resetting force within a certain displacement range, and Impact problems with sudden changes in stiffness
