Washer 2 provided between mounting members such as the beam 18 and the base 19
In the main washer 27, similar bolt holes 7 and nail holes 8 corresponding to the bolt holes 7 and nail holes 8 of the substrate 1 are formed, so that the depth of the nail holes 8 in this case is Since the thickness of the base plate 1 and the thickness of the main washer 27 become the sum of the thickness and the guide of the nail 16 to be driven, the nail 16 is prevented from tilting when the nail 16 is driven, and the driven nail 16 is fixed. The metal fitting 9 can be prevented from moving in the lateral direction. When the above-mentioned brace is constructed, it is usually performed as shown in FIG. As shown in the figure, the fixing bracket 9 is positioned on the spar 18 and the base 19 between the two pillars 17, 17 and one side of the pillar 17 different from each other, and the bolt hole 7 and the nail hole 8 are aligned. It is fixed with a bolt 15 having a nut and a nail 16 respectively.
In this case, the bolt 15 is fixed by penetrating a wooden attachment member such as the beam 18 and the base 19. The brace rod 12 may have its annular portion 10 fitted to the shaft core 6 of each fixture 9 in advance, or after the fixture 9 has been fixed as described above. As described above, in the brace member 13 composed of the fixing metal 9 and the brace bars 12, 12, the brace bars 12, 12 corresponding to the diagonally up and down directions are connected by the turnbuckle 14 and tightened.
