PROBLEM TO BE SOLVED: To securely prevent floor sound generated even in a woody floor in which a tightly-constructed tongue joint is partially formed. SOLUTION: The woody floor is formed by placing a plurality of woody floor materials A having tongues 2, 3 on the under-floor ground 4 while performing tongue joint. A low-viscosity adhesive 30 is infused into the space between vertical cut-end surfaces Q which is at the top of the tongue in the lateral direction of part of the tongue joints of the woody floor materials A. Then the vertical cut-end surfaces Q of the woody floor materials A at least in the lateral direction, which are opposed to each other, are integrally fixed by the infused adhesive 30. Because of this, the displacement of a position can be eliminated which is generated between the vertical cut-end surfaces of the tongue joint of the woody floor materials A in the lateral direction, which are opposed to each other. As a result, floor sound can be prevented. COPYRIGHT: (C)2009,JPO&INPIT
