Anti-pulling system

Abstract

An anti-pulling system comprises an upper connecting plate, a lower connecting plate, an upper layer of sliding mechanism, a lower layer of sliding mechanism and intermediate layers, the upper layer of sliding mechanism and the lower layer of sliding mechanism are respectively connected with the upper connecting plate and the lower connecting plate, the intermediate layer is connected between the upper layer of sliding mechanism and the lower layer of sliding mechanism, and the upper layer of sliding mechanism and the lower layer of sliding mechanism have the same structure, are mounted opposite from each other, and can slide in directions perpendicular to each other. The upper (lower) layer of sliding mechanism comprises n sets of upper (lower) guide rails and upper (lower) sliders, the upper (lower) guide rails are mounted in parallel, the upper (lower) sliders are slidably fitted on the upper (lower) guide rails, the top surfaces of the upper guide rails are connected with the upper connecting plate, the top surfaces of the lower guide rails are connected with the lower connecting plate, and the intermediate layers are respectively connected with the bottoms of the upper sliders and the lower sliders. Under the load action of an earthquake or wind, the anti-pulling system can resist the high upward pulling force of a building structure, meanwhile, the anti-pulling system can allow a seismic isolation structure to slide, resist upsetting moment and enhance the anti-leaning or anti-shaking capability of the building structure, and the anti-pulling system can be used along with intermediate seismic isolation rubber bearings and dampers to form a foundation seismic isolation system which can provide the capability of resisting and balancing the horizontal leaning moment of the structure.

Description

technical field [0001] The invention relates to a shock absorbing and isolating device used in high-rise engineering buildings, in particular to an anti-pulling device. Background technique [0002] Due to the development of urban construction, there are more and more high-rise and super high-rise buildings. High-rise and super high-rise buildings are structures with a relatively large aspect ratio. Under the action of strong external forces such as earthquakes, the acceleration and displacement are large, which will cause the building to tilt. When the inclination is large, it will cause the building to overturn, endangering the safety of the building and people; in addition, strong winds will also cause the building to shake, causing people to panic. The higher the building, the more obvious the shaking caused by earthquakes and winds. Key issues of earthquake resistance.

Problems solved by technology

[0002] Due to the development of urban construction, there are more and more high-rise and super high-rise buildings. High-rise and super high-rise buildings are structures with a relatively large aspect ratio. Under the action of strong external forces such as earthquakes, the acceleration and displacement are large, which will cause the building to tilt. When the inclination is large, it will cause the building to overturn, endangering the safety of the building and people; in addition, strong winds will also cause the building to shake, causing people to panic. The higher the building, the more obvious the shaking caused by earthquakes and winds. Key Issues in Earthquake Resistance

[0003] In order to solve the problems of tilting or shaking of high-rise and super-high-rise isolation buildings with relatively large aspect ratios or other engineering structures under the action of earthquake or wind load, the structural design of buildings has always been based on the seismic design method. , this kind of seismic design is committed to ensuring that the structure itself has sufficient strength, stiffness and ductility to achieve the purpose of mitigating earthquake disasters, but the price paid for this design is huge
