PROBLEM TO BE SOLVED: To provide an earthquake-resistant partition apparatus that is constructed or subjected to earthquake strengthening in conformance with new earthquake-resistance requirements, disposed between a suspended ceiling structure and a floor structure, and is resistant to an inter-layer displacement angle of 1/40, a seismic intensity of 7 and a ceiling surface acceleration of 2.2 G according to the new earthquake-resistance requirements.SOLUTION: Between an earthquake resistant suspended ceiling structure 1 that is constructed on a lower surface side of an upper slab SU and has a clearance G1 with respect to a structure wall W and a floor structure 2 that is constructed on an upper surface side of a lower slab SD, a plurality of struts are vertically provided at predetermined intervals between a top rail 4 attached to a lower surface of the suspended ceiling structure and a ground rail 5 attached to an upper surface of the floor structure, and a panel structure 3 made of an integrated body of the plurality of struts and panels is formed by disposing each panel 7 between the struts, thereby tolerating an in-plane displacement of the panel structure with respect to the inter-layer displacement of the upper and lower slabs and absorbing the displacement between the panel structure and the structure wall using a wall surface unit 8 provided between the structure wall and the panel structure at the time of an earthquake. |
