Easily installable decoration tile

Abstract

An easily installable decoration tile is disclosed, whereby a plurality of tiles can be tightly and securely fastened by allowing the coupling lugs to be inserted into the coupling grooves, and allowing the rugged lugs to be inserted into the rugged grooves, to increase coupling force between tiles, to increase durability of the tiles after construction works are done, to dispense with use of adhesives and to free dwellers from being worried about hazards, and surfaces of coupling lugs and rugged lugs, and coupling grooves and rugged grooves formed on the distal end of the decoration tiles are coated with aerosol to form a coated layer to prevent the decoration tiles from being polluted with liquid foreign objects and to prevent the decoration tiles from being discolored and generating odor.

1 . An easily installable decoration tile that is employed in construction work on an indoor floor surface ( 20 ), the tile comprising: a coupling lug ( 20 ) protrusively formed at a distal end of a tile body ( 10 ) to a lengthwise direction of the tile body ( 10 ); a rugged lug ( 21 ) adjacent to the coupling lug ( 20 ) and protrusively formed at an inner side of the tile body ( 10 ); a coupling groove ( 30 ) formed at the other distal end of the tile body ( 10 ) to a lengthwise direction of the tile body ( 10 ) to correspond to the coupling lug ( 20 ); a rugged groove ( 31 ) formed adjacent to the coupling groove ( 30 ) at an external side of the tile body ( 10 ) to correspond with the rugged lug ( 21 ); and a coated layer ( 40 ) formed on surfaces of the coupling lug ( 20 ) and rugged lug ( 21 ), and the coupling groove ( 30 ) and rugged groove ( 31 ). 
     
     
         2 . The decoration tile of  claim 1 , wherein the coupling lug ( 20 ) is protrusively formed in a trapezoidal shape narrowing from an upper side of the distal end of the body ( 10 ) toward the external side, and the coupling groove ( 30 ) is grooved in a trapezoidal shape narrowing from an upper side of the other distal end of the body ( 10 ) toward an internal side. 
     
     
         3 . The decoration tile of  claim 1 , wherein the rugged lug ( 21 ) is positioned adjacent to a bottom of the coupling lug ( 20 ) to be protrusively formed in three to five screw thread shapes toward an inner side direction of the body ( 10 ), and formed in a lengthwise direction of the body ( 10 ). 
     
     
         4 . The decoration tile of  claim 1 , wherein the rugged groove ( 31 ) is positioned adjacent to a bottom of the coupling groove ( 30 ) at an external side of the body ( 10 ) to be concavely formed in three to five screw thread shapes toward an external side direction of the body ( 10 ) to correspond to the rugged lug ( 21 ). 
     
     
         5 . The decoration tile of  claim 1 , wherein the coated layer ( 40 ) is formed by coating aerosol on surfaces of the coupling lug ( 20 ) and rugged lug ( 21 ), and the coupling groove ( 30 ) and rugged groove ( 31 ). 
     
     
         6 . The decoration tile of  claim 1 , wherein one rugged lug ( 21 ) is formed adjacent to a bottom of the coupling lug ( 20 ) toward an inner side direction of the body ( 10 ) in a screw thread shape, and one rugged groove ( 31 ) is formed adjacent to a bottom of the coupling groove ( 30 ) toward an external side direction of the body ( 10 ) in a screw thread shape.
