The roof fireproof outer insulation structure of the metal roof plate constructed by the construction method of the present invention is constructed as follows. That is, 10 is a metal roof plate (thickness 1 mm) made of a zinc iron plate such as an eye deck roof 30 (trade name, manufactured by Toho Sheet Frame Co., Ltd.) having a flat upper surface. Reference numeral 12 denotes a non-flammable / quasi-non-combustible dew condensation preventing material made of, for example, polyester non-woven fabric-clad rock wool felt (thickness 3 mm) stretched on the lower surface side of the metal roof plate 10 by a dry method. Reference numeral 14 is a fibrous plate-like heat insulation / fireproof material lined with a foam insulation / fireproof material made of, for example, a phenol foam lined rock wool board (thickness: 25 mm) stretched on the upper surface side of the metal roof board 10 by a dry method. It is a material. This phenolic foam lined rock wool board 14
Phenol foam 14b on rock wool board 14a
It is a lining. Reference numeral 16 is a waterproof layer such as a butyl rubber sheet (thickness 1 mm) coated on the upper surface of the phenolic foam-lined rock wool plate 14.

The waterproof layer 16 may be a waterproof plastic sheet, an asphalt sheet, or the like.

In this embodiment, a non-combustible / semi-incombustible dew condensation preventing material 12 made of, for example, polyester non-woven cloth rock wool felt is stretched on the lower surface side of the metal roof panel 10 by a dry method and then molded. , The metal roof plate 10
