PURPOSE:To obtain high sound insulating performance, and reduce component members, and sharply improve construction efficiency. CONSTITUTION:In the upper floor section of a wood construction building whose main constructing members 27, 28 such as a roof, a wall and a beam or the like are composed of wood material, in the case of constructing a floor section, the lower face of a frame body 21 formed of core materials 20a assembled in a frame-shape is first stickedly provided with an inorganic surface material 22 to form a floor panel 20. Next, plural number of the floor panels 20 are arranged with the inorganic surface material 22 set on the side of the lower face and in the direction of the surface, and coupledly fixed by the main constructing members 27, 28. A sound insulating member 35 is next arrangedly provided on the inorganic surface member 22 between the core materials 20a of the floor panel 20. A floor finishing material 23 is then spreadedly provided on the upper face of the floor panel 20 to construct a floor section. |
