FIG. 1 is a sectional view of a substrate 1A made of an inorganic hardened material according to an embodiment, FIG. 2 is a front perspective view, FIG. 3 is a rear perspective view, and FIG. 4 is a construction sectional view.

On the front surface side of the substrate 1A, there are provided ridges (hook portions) 2 extending horizontally in the horizontal direction. The projection 2 has an engaging surface 2a on the upper surface which is inclined upward toward the front, and engages with a dovetail-shaped engaging groove 4 on the back surface of the tile 3. The ridges 2 are provided in a plurality of stages vertically with a predetermined interval.

A slight gap is formed between the vertical surface of the engaging groove 4 of the tile 3 and the front surface of the ridge 2 to ensure air permeability.
5 is an adhesive, B is a breathable waterproof paper, and C is a heat insulating material.

A vertical groove V extending in the vertical direction is provided on the back surface of the substrate 1A. Since the vertical groove V serves as a passage for moisture, the substrate 1A
The substrate 1A can be installed so that the back surface (the surface other than the vertical groove V) of the above directly contacts the breathable waterproof paper B.

An opening (ventilation hole) 6 is provided to connect the front surface of the substrate 1A to the vertical groove V on the back surface of the substrate. Through the opening 6, part of the moisture in the vertical groove V can be discharged to the front side of the substrate 1A.

In this embodiment, the opening 6 is open to the engaging surface 2a of the ridge 2. The water that tries to collect on the locking surface 2a is extracted to the back surface of the substrate 1A through the opening 6, so that the water does not collect on the locking surface 2a. Therefore, the board 1A
It can prevent damage caused by frost damage. The water that has passed through the opening 6 drops through the vertical groove V on the back side of the substrate 1A.

FIG. 5 shows a different substrate 1B, and a horizontal groove H extending in the lateral direction (horizontal direction) is provided on the back surface of the substrate 1B. When this horizontal groove H is provided, moisture on the back side of the substrate 1B easily flows into the vertical groove V through the horizontal groove H, so that the moisture discharging effect is high.
