There are two connected. Since this tile unit 1 can construct a plurality of tiles in one tiling operation and is effective for reducing construction work and shortening the construction period, it has been widely used for construction of interior and exterior tiles. It is used.

  Such a tile unit 1 is manufactured by aligning a plurality of tiles 2 by placing them in a formwork or the like with the back side up, and bonding a connecting body such as paper to the back side of the tile (for example, a special feature). (Kaihei 8-109730). In recent years, a tile unit has been developed in which a net made of a high elastic modulus fiber such as glass fiber is bonded to the back surface of a tile alignment body instead of a synthetic resin film or paper.

FIG. 7 (a) is a schematic longitudinal sectional view showing a method of attaching the tile unit 1 to the wall surface 4. The tile wall 1 is made of a modified silicon-based or epoxy adhesive or the like. The agent layer 5 is applied. In addition, the tile unit 1 of FIG. 7 (a) has shown the cross section which follows the AA line of FIG.
