The tile is brought in a position, vertical to a base (9) of the recess in the angle. The thickness of each tile decreases at its corners or edges. Each tile is formed symmetrically in the cross section. The tile has a convex curved bottom at its corners or edges. Each tile has a partial flat bearing surface (5) within its central area.
