Press-fitted decoration tiles

Abstract

The present disclosure relates to press-fitted decoration tiles installed as finishing materials on an indoor floor surface of a building, an apartment and/or a house is disclosed, wherein a coupling force among decoration tiles is excellent through mutually press-fitted plurality of decoration tiles to prevent the decoration tiles from being distanced and disengaged and to free from adhesive harmful to human body, the press-fitted decoration tiles including a groove unit formed at each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile, and a lug unit formed at each other lengthwise marginal circumference and other cross-wise marginal circumference of the rectangular decoration tile that face the each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile.

1 . A press-fitted decoration tile that is employed in construction work on an indoor floor surface, the tile comprising:
 a groove unit formed at each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile; and   a lug unit formed at each other lengthwise marginal circumference and other cross-wise marginal circumference of the rectangular decoration tile that face the each one lengthwise marginal circumference and one cross-wise marginal circumference of the rectangular decoration tile,   wherein the groove unit includes a lug formed at a distal end of an external side of the decoration tile and a coupling groove formed at an inner side, wherein the lug is formed from a floor surface of the decoration tile at the distal end of an external side with a height lower than a thickness of the decoration tile, and the coupling groove is slantly formed on an upper surface of the decoration tile with a height lower than that of an upper end of the lug, and wherein the lug unit includes a coupling lug formed at a distal end of an external side of the decoration tile and a groove formed at an inner side, wherein the coupling lug is formed at the distal end of an external side of the decoration tile from an upper surface of the decoration tile at a height lower than a thickness of the decoration tile, and the groove is formed on the floor surface of the decoration tile with a height higher than that of a bottom end of the coupling lug, and wherein the coupling lug formed at the distal end of the external side of the lug unit is outwardly slanted at a distal end thereof, an inclination of an outer circumferential surface of the distal end is 40°˜50°, the groove formed at the inner side of the lug unit is slanted at an inner circumferential surface of the external side, and an inclination of the inner circumferential surface of the external side is 10°˜20°.
