After the joint material 11 is hardened, the joint material tile 1C is manufactured by removing the joint material 11 and the tile 12 from the sheet 40A.

  FIG. 11 (b) is a schematic cross-sectional view illustrating an example of a method for manufacturing the jointed tile unit 1D.

  A groove 41a having the same width as the joint width of the joint tile unit 1D is provided on the surface of the sheet 40B. The tiles 22 are arranged at intervals on the surface of the sheet 40B. Next, the joint material 21 is filled in the joint portion and the groove 41a. After the joint material 21 is cured, the joint-attached tile unit 1D is manufactured by removing the joint material 21 and the tile 22 from the sheet 40B.

  FIG. 11 (c) is a schematic cross-sectional view for explaining an example of a method for producing the jointed tile unit 1E.

  First, what adhered the tile 32 on the net 33 at intervals is placed on the surface of the sheet 40A having a flat surface. Next, the joint material 31 is filled in the joint portion. The filled joint material 31 goes around to the back surface of the tile 32 and the side end surface of the net 33. At this time, since the net 33 serves as a spacer and a gap is formed between the back surface of the tile 32 and the front surface of the sheet 40A, the joint material 31 easily goes around from the joint portion to the back surface of the tile 12. After the joint material 31 is cured, the obtained tile unit 1E with joint is removed from the sheet 40A.

  The above embodiment is an example of the present invention, and the present invention is not limited to the above embodiment. For example, the net 33 of the tile unit 1E in FIG. 8 has an orthogonal cross shape composed of warp yarns 33a parallel to one side of the tile 32 and weft yarns 33b orthogonal to the one side. It is not limited to this. For example, it may have a net shape composed of a first yarn extending in an oblique direction with respect to one side of the tile and a second yarn orthogonal to the first yarn. The mesh of the net is not limited to a square or a rectangle as described above, but may be a quadrangle such as a rhombus or a polygon other than a quadrangle such as a hexagon. Furthermore, a so-called 3 comprising a warp yarn, a yarn that obliquely crosses clockwise (for example, 60 ° oblique) with respect to the warp yarn, and a yarn that obliquely crosses counterclockwise (for example, 60 ° oblique). It may be a shaft-type net or a four-axis net with a weft thread orthogonal to the warp thread.
