で、耐用性も優れたものとなる。Therefore, as shown in FIG. 1, the first protrusion 4b of the face plate 3 is formed.
The lateral convex edge 4c is loosely fitted to the lateral member 6a of the metal supporting member 6, and the roller 10 guided by the guide rails is axially attached to the upper side surfaces of the vertical members 6b on the left and right sides. When the shutter curtain 1 is sequentially connected by the chain 11, the entire surface of the shutter curtain 1 on the front surface side is made of a refractory inorganic material, so that the heat-shielding property against the heat of heat is remarkably improved, and the panel 2 in the vertically adjacent portions is Since the face plates 3 of the above form mutually double walls 4, the second ridges 4d formed on the face plate 3 of the upper panel 2 are parallel to the first ridges 4b formed on the face plate 3 of the lower panel 2. It is also polymerized to improve the smoke barrier property and block the smoke from flowing to the back side. In addition, even if the face plate 3 is formed of an inorganic material, the metal supporting member 6 is loosely fitted to the brittleness, which is a drawback thereof.
Since it is reinforced by, the mechanical strength that does not hinder the opening / closing operation during normal opening / closing is maintained, so that the durability is also excellent.

a rib 5a at the center of the concave portion 5 between the b and the lateral convex edge 4c.
Are projected in the longitudinal direction, and the metal supporting member 6 is a face plate 3
Bent portions 6d are formed on both upper and lower edges of the flat surface portion 6c which covers the entire back surface of the above, and which hold the first ridge portion 4b and the lateral convex edge 4c of the face plate 3 in a loose fit manner. Therefore, the first protruding portion 4b and the lateral convex edge 4c of the face plate 3 are formed on the bent portion 6d of the metal supporting member 6.
A bracket for supporting the hinge shaft 12 and the roller 10 guided by the guide rail on the left and right sides of the flat surface portion 6c of the metal supporting member 6 by vertically fitting the panels 2 to each other to form the panel 2. When the shutter curtain 1 is constructed by attaching 13 and sequentially connecting the respective panels 2 vertically so that they can be bent, the upper panel 2 is exactly the same as in the above-mentioned embodiment.
The shutter curtain 1 is configured in such a manner that the second ridge portion 4d formed on the face plate 3 of FIG. 2 and the first ridge portion 4b formed on the face plate 3 of the lower panel 2 form a double wall portion in parallel. .

著な効果を奏する。According to the present invention which requires this, the panel constituting the shutter curtain is composed of a face plate made of a refractory inorganic material and a metal supporting member for supporting the face plate. To the upper side, and the lower end edge on the back surface side is cut out, and the second protruding portion to the front side is formed in the longitudinal direction of the face plate. A metal support member formed by bending the upper and lower edges along the shape of the ridge extends from the rising base of the first ridge to the rear side of the face plate to the rising base of the second ridge. A double wall is formed between the lower edge of the upper panel and the upper edge of the lower panel when the shutter curtain is formed by vertically fitting the panels while fitting in the surface area. Since it is configured as described above, the following remarkable effects can be obtained.
シャッターカーテンの表面側全面が耐火性無機質材の
面板で形成されているため、火災時には火熱に対する遮
熱性を格段に向上させることができる。Since the entire surface of the shutter curtain on the front surface side is formed of a face plate made of a refractory inorganic material, it is possible to remarkably improve the heat shield property against the heat of a fire in the case of a fire.
