Since the heat insulating material 14 and the tile body 12 are mechanically coupled to each other in this way, the two can be secured for a long period of time without relying on the adhesive force of the adhesive as in the conventional case. . An adhesive may be interposed between the heat insulating material 14 and the tile body 12 as in the conventional case, and the two may be joined by the adhesive. Furthermore, when the depth of the recess 18 on the rear surface of the tile body 12 is shallow, the heat insulating material 14
When a sufficient bond cannot be secured between the tile body 12 and the tile body 12 only with the adhesive, an anchor member as described later may be integrally anchored to the heat insulating material 14 and attached to the bonded portion.

On the other hand, the anchor member 16 is the building frame 8
The mortar 6 applied to the surface is anchored and the outer insulating tile 10 is integrally attached to the surface of the skeleton 8. Here, as the anchor member 16, an organic or inorganic fibrous or mesh-like three-dimensional fiber member having napped portions 22a and 22b formed on both surfaces thereof is used.

In the outer heat insulating tile shown in FIG. 2, the concave portion 18 formed on the back surface of the tile body 12 is formed so as to gradually spread in the lateral direction from the opening portion to the bottom portion to form a dovetail groove. It was done. Since the concave portion 18 is a dovetail groove in this manner, the heat insulating material 18 that bites into the dovetail groove is caught and becomes difficult to come out. By forming the dovetail groove as the recess 18 in this manner, the integrity of the tile body 12 and the heat insulating material 14 can be further enhanced.

In the outer insulation tile 10 shown in FIG. 3,
A step portion 14a is formed on the peripheral edge portion of the heat insulating material 14, and the heat insulating materials 14 of the outer heat insulating tiles 10 adjacent to each other are meshed with each other via the step portion to be jointed. By jointing the heat insulating materials 14 to each other in this manner, it is possible to prevent the mortar 6 on the back side of the outer heat insulating tile 10 from leaking to the front side.
