PURPOSE:To prevent occurrence of a difference in levels between flooring materials by making a rigid connecting piece movably housed in a cut-in groove that is provided to the upper part of a flooring material, by placing another flooring material adjoining thereto with the cut-in groove provided at the position roughly corresponding to the above-mentioned groove and by making the connecting piece move to the adjoining groove. CONSTITUTION:An unit type flooring material 4 is formed of a floor board base 1, a sound insulating sheet 2 and a wooden surface piece 3. And to the position of the sound insulating sheet 2 facing an adjoining flooring material, a cut-in groove 5 is provided and a rigid connecting piece 6 made from steel plate or the like is inserted and housed therein so that the piece becomes movable within the groove. Then another flooring material 4' is placed adjoining the first one, and the cut-in groove 5' is provided to the position roughly corresponding to that of the cut-in groove 5. With the adjoining two flooring materials placed side by side, the connecting piece 6 is moved with a magnet 7 placed over the floor surface so that the piece is engaged in both of the adjoining cut-in grooves 5 and 5'. Thereby a tongue is formed in the grooves and by such simple method thereof, a difference in level that degrades a floor function can be prevented from occurring. |
