The shock insulation support is a support device arranged for meeting the shock insulation requirement of a structure, a shock insulation layer is additionally arranged between an upper structure and a foundation, a rubber shock insulation support is installed to achieve soft connection with the ground, and through the technology, about 80% of energy of an earthquake can be offset. Such as laminated rubber mounts (or seismic isolation rubber mounts, laminated rubber pads, etc.). The structural member has small horizontal rigidity and large vertical rigidity, can bear large horizontal deformation, and can be used as a part of a load-bearing system. Such anti-seismic techniques have been derived from the development of rocket engines. Meanwhile, shock insulation rubber supports (called shock insulation supports for short) are commonly adopted for components of shock insulation layers of shock insulation buildings built at home and abroad. Compared with the traditional earthquake-proof structure, the earthquake-proof structure can protect the safety of personnel in the building to a greater extent, more effectively protect indoor facilities and equipment and instruments and reduce property loss. The seismic isolation building structure is a combination form of all members formed for realizing the seismic isolation design requirement of a building structure, and generally does not need to be calculated. The core of the shock insulation structure lies in the treatment of shock insulation seams, and the design of the shock insulation structure is to ensure that an upper structure and a lower structure of a building or an outdoor terrace, and the shock insulation building and an adjacent building or structure are completely separated, so that the horizontal movement of a shock insulation layer is not limited.

There are two main aspects to the study of seismic isolation elements: on one hand, new materials, new processes and new methods are actively explored to develop various shock insulation elements; on the other hand, how to apply the shock insulation support in the engineering practice is researched, and the problems of shock insulation performance and engineering cost of the shock insulation support are considered. The shock-absorbing damper can be used as an independent component or can be used in combination, sometimes the shock-absorbing damper needs to be determined according to the requirements of building functions, the supporting shock isolator mainly bears the load of the upper structure of a building, the shock-absorbing damper mainly controls the horizontal deformation generated by the shock-absorbing support not to exceed the limit value specified in the specification, the shaking of the upper structure of the building is reduced, and the shock-absorbing damper can be reset after the earthquake is finished.
