Further, the folded lower portion 23 and the folded upper portion 24 are formed along the longitudinal direction of the front and rear end portions of the main body 18, and are folded vertically or vertically folded from the main body 18 and then inward. It is folded horizontally with the main body 18 to prevent the intrusion of rainwater and the like, while ensuring the same thickness as the clay roof tiles and improving the strength in the longitudinal direction.

  As shown in FIG. 2, the valley roof tile 11 is formed by cutting the titanium metal plate into a groove plate 25 into a tapered substantially rectangular shape, and the groove plate 25 is formed into the shape by a press molding machine. Yes. This groove plate 25 has a length in the longitudinal direction set to 307 mm and a length in the width direction set to 315 mm. As shown in FIG. 2, a pair of notch grooves 26 are formed on both side end portions and rear end portions. 29 are formed, and the front end 30 is formed in a curved shape.

  Then, as shown by arrows A to E in FIG. 1, after the both side end portions of the groove plate 25 are bent in a curved shape to form the rising portion 19, the center tip of the rising portion 19 is moved to the notch groove. 26 is folded inwardly to form the screw groove 21, the front and rear portions of the rising portion 19 are bent outward to form a nail clamp margin 22, and the front end portion has an L-shaped longitudinal section. The bottom of the fold is formed by forming a folded lower portion 23 while the rear end portion is folded along the notch groove 29 to form the folded upper portion 24.

  Further, a backup material 27 made of styrene foam is interposed between the valley tile 11 and the base plate 13. This backup material 27 is formed in a rectangular shape with a length of 1500 mm in the longitudinal direction and a length of 140 mm in the width direction, and a step of 15 mm is formed for every 250 mm in the longitudinal direction. It is laid down along the direction. On the upper surface of the backup material 27, the valley tiles 12 are rolled up in a row as indicated by an arrow G. Therefore, although the valley tile 12 is set as thin as 0.3 mm, it is reinforced by the backup material 27 and the heat insulating effect of the roof is also improved.

  On the other hand, the roof tile 11 is curved and formed in a semicircular cross section, and has a helical portion 28 engaged with the helical groove 21 in the opening, and the length in the longitudinal direction and the width direction is 300 mm. The titanium metal plate cut into a square shape is pressed and formed. That is, as indicated by an arrow H, the front end of the opening is folded inward to form the helix 28, and the front and rear ends are folded back and brought into contact with the inner peripheral surface.

  The pile roof 12 after this molding has a length in the longitudinal direction set to 290 mm, and the distance between the openings is set to 274 mm. Moreover, the said helical part 28 is formed in the width of 13 mm along the longitudinal direction of an opening part, and prevents the invasion of rain water by the capillary phenomenon after an assembly | attachment.

  Then, as shown in the arrow I, the mountain roof tile 12 is covered with the roof tile pillow 15 while being assembled with the shell groove 21. Thereafter, the pile roof tiles 12 are overlapped with each other every 40 mm in the longitudinal direction, and nails are driven in. Is fixed to the tile pillow 15, whereby a titanium tile roof is constructed.

  Table 1 shows the results of a mechanical property test of industrial pure titanium (thickness 0.5 to less than 15 mm) of “JIS Type 1” and a bending test of the industrial pure titanium (thickness 0.5 to less than 5 mm). Is shown. This mechanical property test shows the results of tensile strength and elongation, and the bending test shows the results of bending angle and inner radius.

According to Table 1, the commercially pure titanium, indicated as tensile strength "210-410N / mm ^2", shown resistant "165 N / mm ² or more", indicated as elongation "27% or more", The bending angle is indicated as “180 °” and the inner radius is indicated as “double thickness”.

  Then, since the valley roof tile 11 and the mountain roof tile 12 are made of “JIS Type 1” industrial pure titanium, they have the same strength as steel and have excellent strength per weight, that is, specific strength. It can be confirmed.

Table 2 shows a mass table of 1 m ² value of the main tile roof made of titanium and the main clay tile roof according to the present embodiment. Here shown the mass of Tanikawara and Yamakawara both roof (1 m ² value), and the mass of the underlying timber of both the roof (1 m ² value).
