Description
Technical Field
The utility model relates to a building structure technical field especially relates to a but device of vertical vibration isolation and horizontal shock insulation for building.
Background
With the rapid development of rail transit including high-speed rail and subways and the continuous encryption of urban rail transit networks, more and more construction projects cannot avoid adjacent or crossing rail transit. According to the statistical data of subway vibration of Beijing, Shanghai and Guangzhou, the ground vibration induced by the subway is mainly vertical vibration. For buildings adjacent to rail transit, when vertical vibration exceeds the national regulation limit, necessary vibration reduction measures are required, especially for buildings with high vibration requirements, such as theaters, concert halls, museums, sophisticated laboratories and the like. Environmental vibration and noise control has become a problem that must be addressed in building structure design.
Earthquake is a natural phenomenon which cannot be avoided by human beings. Under the action of earthquake, the building can be greatly horizontally deformed and even collapsed. The shock insulation technology achieves the shock absorption purpose by prolonging the self-vibration period of the structure, and after the shock insulation technology is adopted, the shock resistance of the building is obviously improved, so that the shock insulation system is suitable for various buildings such as disaster prevention and relief buildings, school buildings, important infrastructure buildings, houses, offices and the like in high-intensity earthquake areas. The seismic isolation technology is one of the most effective means for relieving earthquake disasters, and the seismic isolation technology really makes it possible that a building does not collapse in an earthquake.
The spring vibration isolator is an important means for controlling vertical vibration, however, because the allowable horizontal limit deformation of the spring vibration isolator is very small, generally only 20-50 mm, when the allowable horizontal limit deformation is exceeded, the vertical bearing performance of the spring is sharply reduced, and the control of the horizontal deformation of the spring vibration isolator not exceeding the limit value is a crucial factor for influencing engineering safety. In non-seismic areas, the horizontal deformation of the building is small, and the vertical vibration of the structure can be reduced by adopting the spring vibration isolator. In the earthquake region, the earthquake action can cause larger horizontal deformation of the building, and when the spring vibration isolator is adopted to reduce the vertical vibration of the structure, other measures are needed to be set, so that the horizontal deformation of the spring vibration isolator is controlled within an allowable range.
At present, when a spring vibration isolator is adopted in a seismic region to control vertical vibration, a viscous damper is adopted to control the horizontal deformation of the spring vibration isolator, namely, the damper is arranged on a vibration isolation layer, the deformation of the vibration isolation layer is reduced through the energy consumption of the damper, the horizontal deformation of the spring vibration isolator is controlled within a limit value range, and meanwhile, the vertical vibration damping effect of the spring vibration isolator is not influenced. Because the allowed horizontal displacement of the spring vibration isolator is small, a viscous damper with a large tonnage is needed to limit the displacement of the vibration isolation layer within the displacement limit value of the spring vibration isolator. The large-tonnage damper not only has high manufacturing cost, but also has large internal force of the components at the joint, complex connection structure and limited reliability. Meanwhile, the displacement of the vibration isolation layer is limited within a very small range through the damper, the horizontal equivalent stiffness of the vibration isolation layer is large, the seismic effect transmitted to the upper structure cannot be effectively reduced, the vibration isolation effect is poor, and the ideal target of vertical vibration and horizontal seismic double isolation is difficult to achieve.
