PROBLEM TO BE SOLVED: To improve construction efficiency and quality by providing a horizontal member with a plate member wider than that, which is fixed thereto, and laying a wood large-section long material on the plate member and fixing the same. SOLUTION: A wood plate member 3 is fixed to the upper surface of a horizontal member 2 in a wooden building frame by nails 4 or the like, a square timber large- section long material 1 is laid on the upper surface of the plate 3, and the long material 1 is fixed from the lower surface of the plate 3 by nails 4 or the like. Secondly, tongues are provided on mutual adjacent surfaces if desired, and after the plate member 3 is fixed on the horizontal member 2, with the tongues suitably stored rather closely, the long material 1 is temporarily placed up to the end of the floor surface. After the gap between the mutual adjacent parts of the long material 1 is substantially equally expanded, the long material 1 is fixed to the plate 3. Subsequently, a gap is provided on a header side of the long material 1 to be loaded with gap filling member. Thus, nails can be easily driven, torsion of a large-section long material, which is probably caused with the passage of time can be restrained, and deformation due to expansion and shrinkage caused in the lower surface of the large-section long material can be restrained so as to hardly cause play of the floor.
