Fire-resistant composition, panel and external wall for various buildings

Abstract

A fire resistant composition for forming a fire resisting lining is characteristically and substantially composed of ettringite contained as a main ingredient. A panel that is attachable to a building body so as to form an external wall thereof is composed of a base plate and the fire resisting lining that contains ettringite as its main ingredient and covers the base plate. A structure of an external wall of buildings, the structure has the panels attached to the building body to form a plane and having their sides adjoined one to another, and the base plate in each panel has a periphery not covered with the lining. A groove-shaped cavity appearing between the adjacent lining edges facing one another is filled with a caulking material, so that the fire resistance afforded by the composition and the panels is further enhanced.
