Description

  The present invention relates to a support device that supports an external temporary structure for a base isolation structure and a base isolation scaffold using the support device.

  To alleviate the shaking of earthquakes, high-rise buildings and tower apartments are equipped with seismic isolation devices. Even in seismic isolation buildings such as high-rise buildings and tower condominiums, exterior wall repair work, etc., locks the seismic isolation device of the building body during the construction period so that the seismic isolation device does not operate during an earthquake. . However, even during the construction period, there is a possibility that a big earthquake will occur. In this case, the external scaffolding may collapse due to the lock being released and the building body shaking greatly. To cope with this, seismic isolation structures for scaffolds have been proposed. Patent Documents 1 and 2 disclose a technique in which a scaffold support member is connected to a base isolation structure, and the scaffold support member itself can slide in the horizontal direction together with the base isolation structure.
