Building seismic structure simulation device

Abstract

The invention discloses a building anti-seismic structure simulation device. The fixed support includes a plurality of fixed rods, and the plurality of fixed rods can be raised and lowered on the table surface of the external vibration table, and the upper end of the fixed rod is detachably connected with the external experience table. A disassembly and assembly device for a support and a table top, the disassembly and assembly device comprises a disassembly and assembly base arranged on the table surface and a rotatable rotating sleeve sleeved on the disassembly and assembly base. In the building earthquake-resistant structure simulation device of the present invention, by setting the switching device to switch the motor and link it with the disassembly and assembly device, it can effectively realize that the seismic isolation support can be completely detached when it is fixedly connected, so that it can be better conducted an experience experiment.

Description

technical field [0001] The invention relates to a seismic isolation experience platform, and more particularly to a simulation device of a building seismic structure. Background technique [0002] Seismic-isolated buildings and traditional seismic-resistant buildings will have different effects when an earthquake occurs. Because of the seismic isolation system, the superstructure of the seismic-isolated buildings slowly translates, while the traditional seismic-resistant buildings sway very strongly from side to side. How to let 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 we can only respond objectively through disaster investigation after the earthquake; large-scale shaking table tests can simulate earthquakes more realistically to understand isolation. The advantages of seismic structures can only be carried out in laboratories with large ...

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
