The foundation vibration isolation is a simple and effective damping technology, has been widely applied to buildings, and has a good damping effect. However, when the shock insulation technology is applied to shock insulation buildings with high intensity areas and large height and width due to the defect that the tension capacity of the rubber support is poor, the shock insulation support is often in overturned failure due to the fact that the tension capacity of the shock insulation support exceeds 1MPa, so that the shock insulation technology cannot be adopted.
In order to improve the anti-capsizing capability of the basic shock insulation building and expand the application range of the shock insulation technology, some students do relevant research and engineering practice, such as: the Fuzhou university Qi Ai and the like propose a construction measure that vertical steel bars are added at the edge support to improve the tension safety of the shock insulation rubber support, but the tie action of the vertical steel bars added at the edge support increases the horizontal rigidity of the shock insulation layer, limits the horizontal deformation of the shock insulation layer and influences the shock absorption effect; the harbine industrial university Yan Xueyuan and the like connect the horizontal and vertical vibration isolation sub-devices in series, develop three types of three-dimensional vibration isolation anti-overturning supports, and overcome the defect of poor tensile property of the rubber support to a certain extent, but the device is complex, has higher production and manufacturing difficulty and high manufacturing cost, and is not beneficial to engineering application; three rubber supports are connected in parallel to convert tension into pressure to prevent the supports from being pulled, but the parallel supports are large in size, difficult to apply in a narrow shock insulation layer and not beneficial to popularization and application, and the like are proposed by Hunan university Su Jian; lead core Laminated Rubber Supports (TLRBs) with a tensile function are proposed by the university of the same company Wang Dong and the like, but the horizontal deformation capacity of the support is limited by a tensile rope of a central hole of the support, so that the horizontal damping effect is influenced, and the large deflection behavior of a shock insulation layer is difficult to adapt; the chinese aviation design institute Ge Guqi, etc., developed a "door" shaped tensile device and applied it to the shock insulation engineering of the dubbing museum, but the "door" shaped tensile device was simulated with a "hook" unit at the design stage, which is difficult to simulate the gap between the rubber mount and the "hook" unit, so that the design stage of the additional tensile device is assumed to have a difference from the actual working stress state; the seismology technology also develops a slide rail type tensile device, but the tensile capability is limited due to the influence of the slide rail structure, and the installation structure is complex.
