PURPOSE: To let a tile be firmly set onto a building frame with ease by provid ing the tile with a slant which is formed by chamfering, thereby setting the tile while the tile is being fixed by means of the slant piece of a fixture the fixing piece of which is fixed into a wall bed.

CONSTITUTION: More than two sides of a tile in a square, a rectangular or in a polygon as a front face form, which has two parallel sides at the opposite sides, are chamfered so that each slant 2 is formed. In the second place, the fixing piece 4 of a fixture 3 is fixed in a wall bed, the tile 1 is set thereafter from one side toward the opposite direction while the tile 1 is being movably supported by two slant pieces 5 and 6 at the two sides of the slant 2. Therefore, the tile can be firmly set so that it will never come off even when it is subjected to physical impact such as earthquakes, fire and the like.
