Prefab material for adjusting level of floor

Abstract

The present invention relates to a sectional floor-covering capable of adjusting level, which includes a height adjusting block; a supporter coupled to the upper surface of the height adjusting block; slip floorings coupled to the upper surface of the supporter; and horizon adjusting devices mounted to the height adjusting block. The height adjusting blocks and supporters are assembled and installed at a desired position, and slip floorings are mounted and fixed on the assembled height adjusting blocks and supporters so as to install the floor to a wanted height.

1 . A sectional floor covering capable of adjusting level, the sectional floor covering comprising: 
 a height adjusting block;    a supporter coupled to the upper surface of the height adjusting block;    slip floorings coupled to the upper surface of the supporter; and    horizon adjusting devices mounted to the height adjusting block,    wherein the height adjusting block includes:    connecting tongues formed on the upper surface of the height adjusting block;    vertical holes perforating the upper and lower surfaces of the height adjusting block; and    built-in nuts embedded and fixed into the vertical holes,    wherein the supporter includes:    connecting holes formed in the lower surface of the supporter and coupled with the connecting tongues;    vertical working holes formed in positions corresponding to the vertical holes under a condition in which the supporter is coupled with the height adjusting block, and perforating the upper and lower surfaces of the supporter;    connection protrusions extending from a side of the upper surface of the supporter and protruding vertically;    connection receiving parts extending from the other side of the upper surface of the supporter; and    slip flooring connection pins formed on the upper surface of the supporter, wherein the connection protrusions are coupled with the connection receiving parts formed on another supporter, which is installed adjacent to the present supporter,    wherein the sling flooring includes a coupling groove formed in the lower surface thereof, receiving the slip flooring connection pin and coupled with the supporter,    wherein the horizon adjusting device includes:    a screw bar having a screw thread;    a head part formed at a side end portion of the screw bar; and    a driver hole of a “+” or “−”shape formed in the front end of the other side end portion of the screw bar, wherein the screw bar is inserted into the lower surface of the height adjusting block and coupled with the built-in nut.    
   
   
       2 . A sectional floor covering capable of adjusting level according to  claim 1 , further comprising a locking nut fastened to the screw bar of the horizon adjusting device.  
   
   
       3 . A sectional floor covering capable of adjusting level according to  claim 1 , wherein the head part of the horizon adjusting device is packed with a rubber cover.  
   
   
       4 . A sectional floor covering capable of adjusting level according to  claim 1 , wherein the height adjusting block has drain holes formed in the lower surface thereof.  
   
   
       5 . A sectional floor covering capable of adjusting level according to  claim 1 , wherein the height adjusting block has connecting grooves formed in the lower surface thereof, so that a number of height adjusting blocks can be piled up by coupling the connecting tongues and the connecting grooves with each other.
