Embodiment
[0033] This embodiment provides a tension-limiting combined seismic isolation bearing used in construction, which is arranged between the upper structure and the lower foundation to provide seismic isolation support for the upper structure. The tensile limit combined type seismic isolation bearing includes an upper connecting piece 1,
[0034] Adjusting member, rubber bearing 5 and lower connecting piece 6. Wherein, the upper connecting piece 1, the rubber bearing 5 and the lower connecting piece 6 are fixedly connected sequentially from top to bottom. In this embodiment, up, down, left, right, top, and bottom are only relative positions shown in the drawings of the specification, and are not used to limit positions in actual space.
[0035] Such as figure 1As shown, the upper connector 1 includes a top plate 19 , side walls 20 and a bottom plate 21 . The top plate 19 is a square plate, with a square hollow in the middle, and several orderly arranged superstructure connecti...

The invention provides a combined anti-tension and position-limiting shock-isolation bearing, which includes: an upper connector, a rubber bearing, a lower connector, a cover plate, a plurality of elastic members and a plurality of steel wire ropes, and the cover plate is arranged on the upper connector box In the cavity and the top surface of the cover plate is lower than the top surface of the upper connector, the elastic member is arranged between the cover plate and the upper connector, the rubber bearing is arranged between the bottom plate of the upper connector and the lower connector, and the box-type cavity There is a limit device in the body, and the steel wire rope passes through the box-type cavity, one end of which is anchored on the cover plate and the other end is anchored on the lower connecting piece; when the rubber bearing is subjected to tension, the steel wire rope transmits the tension to the elastic member to bear part of the tension ; When the rubber bearing is deformed too much due to shearing or tension, the limit device restricts its continuous deformation, so that it can not only achieve the shock isolation effect of ordinary vibration-isolation bearings, but also ensure that the rubber bearing itself can withstand a large tensile force. The structure is not easy to be damaged, thus effectively ensuring the safety and reset capability of the upper structure under the action of earthquake.
Description
technical field [0001] The invention belongs to the technical field of seismic isolation and shock absorption of building structures, and relates to a seismic isolation support. Background technique [0002] The base isolation structure is a structural system formed by installing an isolation device between the structure and the foundation to prolong the natural vibration period of the structure, increase the structural damping, and prevent the transmission of seismic energy to the upper structure to reduce the Effects of earthquakes on structures. Lead core laminated rubber bearing is a widely used seismic isolation device. When in use, its top surface and bottom surface are respectively connected and fixed with the upper structure and the foundation, so that it can not only bear the vertical load of the upper structure, but also because of its It has lateral flexibility and can block the upward transmission of seismic energy, and can also consume and absorb seismic energy...
