| 摘要 |
The present invention relates to a curved under-tile or covering-tile with the width of the tile decreasing from one end to the other in order to allow the fitting of a plurality of tiles in the form of a line with interlocking between tiles by means of tenons produced on the concave face of the tile near its wider end and near each of its lateral edges with housings made in the other end of the tile. In accordance with the invention, the said tenons 13 are delimited towards the inside of the tile by a surface 15 which is parallel to, or diverges with respect to, the internal axial plane 16 of the tile. The invention makes it possible to disassemble laid tiles in order to change them and stack them head to tail. <IMAGE>
