Position limiter of building vibration -isolation system

Abstract

The position limiter of building vibration-isolating system is set inside the vibration-isolating layer, which includes the upper structure plane comprising beam slab and movable base, the lower structure plane comprising beam slab and fixed base, and the vibration-isolating device between the upper structure plane and the lower structure plane. There are upwards raised lower limiting block in the lower structure plane, downwards raised upper limiting block in the upper structure plane, and interval between the side of the lower limiting block and that of the upper limiting block, with the top of the lower limiting block being higher than the bottom of the upper limiting block. A building has at least one vibration-isolating layer, and some spacer block is set between the side of the lower limiting block and that of the upper limiting block to constitute locking device.

Description

Technical field [0001] The present invention relates to a limit device for a seismic isolation system of a building, which is also suitable for structures, bridges and other objects that need seismic isolation Background technique [0002] Existing building isolation systems mainly rely on damping devices to dissipate energy and limit the position, and the reliability of this limit function is not high due to the complexity of the seismic force. The other hard collision limit mechanism is set between the fixed foundation and the movable foundation. Due to the narrow range and limited component limit force, its application range is limited. The limit of the entire building is limited to one seismic isolation layer, which is almost impossible to achieve in the strong earthquake zone, especially when the ground displacement is large and the building volume is large. Summary of the invention [0003] The present invention proposes a limit device for a seismic isolation system of a b...

Problems solved by technology

[0002] The existing building isolation system mainly relies on the energy dissipation of the damping device to limit the position. Due to the complexity of the seismic force, the reliability of this limit function is not high.

Another kind of hard collision limit mechanism is set between the fixed foundation and the movable foundation. Due to the narrow range, the limit force of the components is limited, resulting in a limited scope of application.
