Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of shock isolation pile structures. BACKGROUND

[0002] Traditional building is fixed on ground, since the building weight is large, and the vibration frequency of building is very close to earthquake, so there are many buildings collapsed in many previous large earthquakes. The isolation technology is to build house on isolation support, and the isolation support has deformation capacity in horizontal direction, so that the upper building and ground movement are isolated. During earthquake, the deformation of building is mainly concentrated in isolation layer, and the upper building is less affected by earthquake. In high earthquake risk area, isolation technology can reduce the design load of upper house, and save the cost of building. For functional buildings such as hospital, disaster command center and laboratory, isolation technology can reduce the vibration in building during earthquake, protect property safety and building function.

[0003] The laminated rubber support is generally composed of alternating rubber layers and metal plate layers, and has various shapes which can be designed according to actual needs. The rubber layer in the laminated rubber support is the main bearing part of the laminated rubber support, which can absorb and disperse the force of load. The metal plate layer in the laminated rubber support is a metal plate between the rubber layers, which provides support and fixes the rubber layers. When the laminated rubber support bears load, the rubber layer will compress and deform, thereby generating elastic deformation force. The elastic property of the laminated rubber support makes it have good shock absorption and vibration isolation effect, which can reduce the influence of external vibration such as earthquake and traffic vibration on the structure. However, the laminated rubber support has poor deformation reset ability. When the horizontal displacement is within 5 cm, it can be reset accurately, but if the horizontal displacement exceeds 5 cm, the laminated rubber support has the problem of difficult reset. SUMMARY
