The floor material provided with the spring swinging It is configured to press to the position, and the locking piece fixed to the tip of the elastic material is locked to the locking part fixed to the building wall material, so that the elastic material can be locked The telescopic shape assembly is installed between the lower surface of the border material and the foundation floor surface, and the telescopic shape assembly expands and contracts in response to the swinging of the floor material when an earthquake occurs. Provided is a seismic isolation swing floor characterized in that it is configured to hold a border material.

  According to the present invention, the entire flooring rocks together with the floorboard holding structure when an earthquake occurs, and does not collapse the frame on the floor surface. When moving to, it is possible to restore from the moving position to the original position, and to maintain the chassis and electronic equipment on the floor without collapsing.

  In addition, even when an earthquake stops, the floor is always restored to its initial state so that the frame and electronic equipment on the floor can be maintained.
