Description
Technical Field
The invention relates to the technical field of seismic isolation and resistance equipment, in particular to a tensile, shearing and seismic isolation support.
Background
The basic shock isolation technology is a shock isolation (vibration) reduction technology in which a shock isolation device is arranged at the bottom of a building structure, and is technically characterized in that the shock isolation device can effectively cut off horizontal earthquake acting force and reduce horizontal vibration of an upper structure, so that the upper structure is effectively protected. The conventional vibration isolation support products which are applied more mainly comprise a common laminated rubber support, a lead core rubber vibration isolation support and a high-damping vibration isolation support.
With the issuance and implementation of related seismic isolation specifications, seismic isolation technology gets more and more extensive attention and application, and more seismic isolation support products are widely applied to various seismic isolation structures.
At present, the laminated rubber shock-insulation support which is widely applied is mainly formed by alternately laminating die-pressed vulcanized rubber and steel plates between an upper connecting plate and a lower connecting plate. When the laminated rubber vibration-isolating support is subjected to axial pressure, the reinforcing plate is bonded with the rubber layer, the transverse deformation of the rubber layer is restrained by the reinforcing plate, and the vertical deformation of the vibration-isolating support is smaller, so that the vibration-isolating support has higher vertical bearing capacity; however, the inventor of the application finds that when the laminated rubber vibration isolation support is subjected to a horizontal shearing force, the internal reinforcing plate does not restrict the shearing deformation of the rubber layer, so that the rubber layer can generate larger transverse deformation in the horizontal direction, and the shearing damage is caused; in addition, when the laminated rubber vibration isolation support is axially stretched, the inside of the rubber can form a negative pressure state, cavities are easily generated inside the laminated rubber vibration isolation support to be damaged, and the rubber layer is broken or the interface of the rubber and the steel plate is bonded and damaged seriously, so that the laminated rubber vibration isolation support is damaged by tension.
The inventor of the application finds that when the vertical tensile stress reaches 1.5-3.0 MPa, the vertical tensile rigidity of the shock isolation support is rapidly reduced, and compared with the compressive capacity of the shock isolation support of 10-15 MPa, the tensile performance of the laminated rubber shock isolation support is obviously poorer. Therefore, the tensile property of the existing laminated rubber shock-isolation support is difficult to meet the current shock-isolation requirement, because the earthquake has multidimensional characteristics, particularly, the high-rise building is easy to swing and even overturn when the high-rise building is positioned in a high-intensity area of the earthquake, the shock-isolation support can bear huge tensile force, and the existing laminated rubber shock-isolation support obviously cannot meet the requirement completely.
