Technical Field
The invention relates to a structural shock insulation support, and belongs to the field of structural engineering shock insulation and reduction.
Background
With the development of economy, a plurality of structures with irregular planes and spaces appear, and the seismic isolation technology is needed to reduce the seismic requirement, so that the seismic safety performance is improved. However, the seismic isolation structure is often subjected to the condition that a seismic isolation layer is pulled, for example, (1) the aspect ratio of the seismic isolation structure is large, when the earthquake is large, the upper structure is subjected to swinging and shaking, and a rubber support at a part of the position is pulled; (2) the plane arrangement of the shock insulation structure is irregular, and the eccentric torsion effect is obvious during earthquake, so that some rubber supports are pulled; (3) the vertical earthquake and the horizontal earthquake act simultaneously, so that some rubber supports can be in a stretching state; however, the tensile strength of the rubber shock insulation support is very low, and under the simultaneous action of horizontal and vertical earthquakes which are rarely encountered, the support can be damaged when the tensile stress is greater than 1Mpa, and the rubber layer of the support can be broken and damaged when the support is continuously increased, so that the safety of the structure is influenced.
In order to prevent the rubber shock-insulation support from being damaged by tension, some researchers mainly research and develop various tension-preventing devices which are attached to the periphery of the shock-insulation support to limit the tension deformation of the rubber shock-insulation support from the 'blockage' angle, so that the tension-preventing devices are required to have enough rigidity and strength to resist the tension deformation of the structure. And adopt the thought of "putting", follow the angle development tensile enhancement mode isolation bearing that improves rubber isolation bearing deformability, can avoid setting up and prevent drawing the device, can guarantee isolation bearing's safety again, have important meaning to the development of engineering structure isolation technology.

and each rubber layer is provided with a through seam with the middle symmetrical surfaces parallel to each other, and the rubber on the same layer is vertically disconnected. The steel deck is not broken.
Each rubber layer on each side of the symmetrical plane can be provided with n through seams, and n is a natural number of 1-3.
The energy dissipation component is a lead core or other metal materials with low yield point (the strength is lower than that of common steel materials and is 345 MPa).
Compared with the prior art, the invention has the following characteristics and beneficial effects:
(1) under the action of the same tensile force, the vertical deformation of the shock insulation support is large, n slits are arranged, the n-time deformation capacity can be improved, and the number of the slits can be set according to the deformation requirement.
