Device for joining floor tiles and installation method thereof

Abstract

A device for joining floor tiles, having at least one joint unit; each joint unit has an L-shaped frame and a floor tile fixing plate; the L-shaped frame is provided with block members intersected with each other. The L-shaped frame is provided with inner engaging slots and outer engaging slots at an inner side and outer side respectively on upper surfaces of the block members. The inner engaging slots are engaged with inner engaging hooks disposed on the floor tile fixing plate. The outer engaging slots are engaged with outer engaging hooks on bottom sides of floor tile fixing plates of adjacent joint units. Also provided is an installation method of floor tiles.

1 . A device for joining floor tiles, comprising at least one joint unit; each joint unit comprises an L-shaped frame and a floor tile fixing plate; an upper surface of a straight vertical arm of the L-shaped frame and an upper surface of a straight horizontal arm of the L-shaped frame are each provided with a block member; the block member of the straight vertical arm and the block member of the straight horizontal arm are configured to be intersected with each other; inner engaging slots are provided on an upper surface of the L-shaped frame at an inner side of each block member; outer engaging slots are provided on an upper surface of the L-shaped frame at an outer side of each block member; the inner engaging slots engage with inner engaging hooks disposed on a bottom surface of a corresponding floor tile fixing plate along two adjacent peripheral edges of the corresponding floor tile fixing plate; the outer engaging slots engage with outer engaging hooks provided on a bottom surface along a peripheral edge of each of two other floor tile fixing plates of corresponding two other adjacent joint units. 
     
     
         2 . The device of  claim 1 , wherein the inner engaging hooks and the outer engaging hooks have identical structures and are evenly distributed on the bottom surface of each floor tile fixing plate along four peripheral edges thereof. 
     
     
         3 . The device of  claim 2 , wherein each of the inner engaging hooks has a left hook and a right hook spaced apart and symmetrically arranged. 
     
     
         4 . The device of  claim 3 , wherein a positioning slot is provided between every two adjacent inner engaging slots; each positioning slot matches with a corresponding positioning block also provided between every two adjacent inner engaging hooks. 
     
     
         5 . The device of  claim 1 , wherein the block member has a height greater than a thickness of the floor tile fixing plate but smaller than a thickness of a floor tile. 
     
     
         6 . The device of  claim 1 , wherein an upper surface of the floor tile fixing plate is applied with an adhesive layer for fixing a floor tile. 
     
     
         7 . The device of  claim 1 , wherein an upper surface of the floor tile fixing plate is opened with anti-shrinking through holes through the floor tile fixing plate; a bottom surface of the floor tile fixing plate is provided with supporting rods extending downwardly. 
     
     
         8 . An installation method of floor tiles using the device of  claim 1 , comprising the following steps:
 joining the L-shaped frame and the floor tile fixing plate to form the joint unit; more than one of said joint unit is formed; assembling all the joint units on a level ground;   removing a release paper on an upper surface of an adhesive layer of each floor tile fixing plate;   after the device is assembled, placing each of the floor tiles into a corresponding rectangular opening enclosed by the block members; adhering each of the floor tiles with a corresponding floor tile fixing plate removed of the release paper; and   filling in gaps between adjacent floor tiles by using seam filling adhesives.   
     
     
         9 . The installation method of  claim 8 , wherein the adhesive layer of the floor tile fixing plate is a layer of self-adhesive material. 
     
     
         10 . The installation method of  claim 8 , wherein in each row of L-shaped frames disposed on the level ground, one end of a corresponding L-shaped frame is joined with a vertical straight arm of another adjacent L-shaped frame.
