ルのアイソレータ用耐火被覆。[Scope of Claim for Utility Model Registration] (1) A fire-resistant cylindrical body whose upper part is fixed to the upper structure and is droopingly covered on the outer peripheral surface of the isolator so as to surround the isolator, and a fire-resistant cylindrical body that is attached to the inner peripheral surface of the lower end of the cylindrical body. It consists of a fire-resistant annular body that is fitted securely and placed on the lower structure so as to be slidable on the surface of the lower structure and to surround the base of the isolator, and is integrated with the rocking movement of the upper structure. A fire-resistant coating for an isolator of a seismically isolated building, comprising a fire-resistant annular body that is lock-fitted to the inner peripheral surface of the lower end of the fire-resistant cylindrical body and moves integrally with the cylindrical body. (2) The fire-resistant cylindrical body has a facing dimension from the outer circumferential surface of the isolator to the inner circumferential surface of the cylindrical body that is greater than or equal to the horizontal displacement dimension of the isolator, and the hanging edge of the cylindrical body is such that the lower end of the cylindrical body is close to the surface of the lower structure. A fireproof coating for an isolator of an earthquake-isolated building according to claim 1, wherein the fireproof coating is separated from the isolator by more than the vertical displacement dimension of the isolator.
