Building anti-seismic structure simulation device

Abstract

The invention discloses a building anti-seismic structure simulation device. The building anti-seismic structure simulation device comprises a vibration isolation support and a fixed support which areboth connected between an external vibration table and an experience table, and a switching device used for switching the vibration isolation support and the fixed support; the fixed support comprises a plurality of fixed rods, and the plurality of fixed rods are arranged on the table surface of the external vibration table in a lifting mode, and the upper ends of the fixed rods are detachably connected with the external experience table; the switching device comprises a switching motor and a dismounting and mounting device used for disassembling and mounting the vibration isolation support and the table top; and the dismounting and mounting device comprises a dismounting and mounting base arranged on the table surface and a rotating sleeve rotatably sleeved on the dismounting and mounting base. According to the building anti-seismic structure simulation device, the switching device is arranged into the switching motor and is in linkage with the dismounting and assembling device, so that the vibration isolation support can be completely separated when fixedly connected, and the experience experiment can be better carried out.

Description

technical field [0001] The invention relates to a seismic isolation experience platform, in particular to a simulation device for an anti-seismic structure of a building. Background technique [0002] Earthquake-isolated buildings and traditional earthquake-resistant buildings will have different effects when an earthquake occurs. The upper structure of earthquake-isolated buildings will move slowly due to the earthquake-isolation system, while the upper structure of traditional earthquake-resistant buildings will sway violently from side to side. How to make people understand the advantages of the isolation structure has always been the purpose of our publicity. It is not conducive to people's observation during a real earthquake, and can only respond objectively through disaster investigation after the earthquake; large-scale shaking table tests can compare real simulated earthquakes to understand isolation. This method has the advantages of seismic structures, but can onl...

How to make people understand the advantages of the isolation structure has always been the purpose of our publicity. It is not conducive to people's observation during a real earthquake, and can only respond objectively through disaster investigation after the earthquake; large-scale shaking table tests can compare real simulated earthquakes to understand isolation. advantages of seismic structures, but can only be performed in laboratories with large shaking tables, and is not repeatable and expensive

[0003] Therefore, in the prior art, an anti-seismic building simulation device will be set up to simulate two common anti-seismic structures in the prior art, one is anti-seismic through the isolation bearing, and the other is anti-seismic by strengthening the connection structure, and Switch between the two structures through a switching device so that people can effectively experience the difference between the two structures. However, the switching principle of the existing switching device is to switch by setting a changeable rigid connection structure In the prior art, the telescopic piston rod of the hydraulic cylinder and the magnetic connection between the electromagnetic coil and the silicon wafer are respectively provided to realize the switching effect. The connection relationship between the vibration seat and the experience seat, and there will still be a certain movable space after the connection, so it will not be possible to more comprehensively simulate the existing transmission fixed connection method, so that the experiencer cannot better experience the traditional The difference between the building structure and the building structure with the addition of seismic isolation bearings
