[0008] An embodiment of a batten tile will be described with reference to Figs. 1 to 4. As shown in Fig. 1(a), cross tiles 10 are installed in order on the roof substrate to form the flat surface of the roof. The cross tiles 10 are installed such that the cross section 12 covers and conceals the insertion section 11 of the installed cross tile 10 from above. The cross tiles 10 are also installed such that the head section 14 covers and conceals the bottom section 13 of the installed cross tile 10 from above.

[0009] As shown in Fig. 1(b), the cross tile 10 has a tile surface 15 and a head end surface 16. The head end surface 16 is continuous with the tile surface 15 at the end on the head 14 side. The corner formed by the tile surface 15 and the head end surface 16 is called a head end 17. At the head end 17 of the cross tile 10, the angle θ between the tile surface 15 and the head end surface 16 is an acute angle.

[0010] The angle θ is an angle according to the inclination angle of the tile surface 15 when the batten tile 10 is actually installed, and is the angle at which rainwater that has traveled along the tile surface 15 to reach the head end 17 falls from the head end 17 without traveling along the head end face 16. The angle θ is preferably equal to or greater than a predetermined angle at which a decrease in strength at the head end 17 is suppressed. The angle θ is preferably within the range of 76°±4°.

[0011] (Manufacturing method) As shown in FIG. 2, the manufacturing method of the batten tile includes a rough surface forming step (step S101), a molding step (step S102), a processing step (step S103), a drying step (step S104), and a firing step (step S105).

[0012] In the rough surface forming step (step S101), the clay as the raw material is kneaded and the air in the clay is removed, and then a rough surface having a shape similar to that of the batten tile 10 is formed. In the molding step (step S102), the rough material is set in a mold and pressed by a press to form a green mold for the tile 10.

[0013] In the processing step (step S103), various processes are performed on the green mold while it is set in a predetermined jig. For example, a hole drilling process is performed to form the through holes 18 (see FIG. 1) used to fix the tile 10.

[0014] 3, with the green mold 20 set in a jig 21, taper processing is performed by cutting a part of the green mold 20 so that the angle θ between the tile surface 15 and the head-side end face 16 becomes an acute angle. The taper processing is performed using a processing tool 23 such as a metal spatula.

[0015] In the drying step (step S104), the green mold that has been subjected to various processes is thoroughly dried. In the firing step (step S105), the dried green mold is fired according to a predetermined firing schedule, thereby producing the cross tile 10.

[0016] (action) As shown in Figure 4, in the case of a shingle tile 10, the angle θ between the tile surface 15 and the head end face 16 is an acute angle, so that rainwater 25 that runs along the tile surface 15 to reach the head end 17 falls without running down the head end face 16.

[0017] The effects of this embodiment will be described. (1) Since the angle θ between the tile surface 15 and the head side end face 16 is an acute angle, drainage at the head side end 17 can be improved.

[0018] (2) By setting the angle θ to a predetermined angle or more, the drainage at the head end 17 can be improved while suppressing a decrease in strength.

[0019] (3) The angle θ is made acute by tapering the green mold 20. This eliminates the need to create a new mold. In addition, the angle θ can be easily changed depending on the inclination of the shingle 10 when actually installed.

[0020] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. The angle θ can be changed appropriately according to the inclination of the cross tile 10 when actually installed.

[0021] In the above embodiment, in the processing step (step S103), the angle θ between the tile surface 15 and the head side end face 16 is made acute by tapering the green mold 20 using the processing tool 23. However, the present invention is not limited to this, and the angle θ between the tile surface 15 and the head side end face 16 may be made acute by changing the shape of the mold and pressing when forming the green mold 20.

[0022] The technical ideas that can be understood from the above-described embodiment and modified examples will be described. (Appendix 1) The angle between the tile surface and the head side end face is 72° or more, which makes it possible to improve drainage at the head side end while suppressing a decrease in strength.

[0023] (Appendix 2) The angle between the tile surface and the head side end face is 80° or less, which can more reliably improve drainage at the head side end. [Explanation of symbols]
