The screw nail 6 is driven into the mounting holes 52 and 53 of the vertical material contact plate portion 12 and the horizontal member contact plate portion 13 and fixed. Although the screw nail 6 is used in the present structure, the bracing 4 may be fixed to the joint using ordinary nails, screws, screws, coach bolts or the like. In this way, the bracing 4 can be firmly fixed to the joint between the vertical member 2 and the horizontal member 3.

The bracing fixing structure of the present embodiment is
A structure in which a brace 4 is fixed to a joint between a column 2 as a vertical member and a base 3 as a horizontal member using the brace fixing bracket 1, and an end 4 a of the brace 4 is It is processed into a shape along the above-mentioned joint, and the above-mentioned brace abutment plate 11 is abutted and fixed to the side surface 4a of the brace with a nail, a screw, or the like, and the above-mentioned vertical material abutment plate of the brace fixing bracket 10 Numeral 12 is fixed to the upper surface 2a of the column 2 and the horizontal member contact plate 13 is fixed to the side surface 3a of the base 3 by nails or screws.

According to the brace fixing structure of the present embodiment, as shown in FIG. 3, the brace fixing is performed so as not to interfere with other structural hardware such as the hole-down hardware 7 for securing the strength of the structure. Since the metal fittings are fixed, a synergistic effect of the effect of other structural hardware and the effect of bracing can be expected. That is, even after the brace 4 is fixed, the brace fixing bracket 1 does not become an obstacle, and the hole-down hardware 7 can be easily arranged along the column 2, or Even if the base is tightened by the hole-down hardware 7 prior to fixing the brace 4, the brace 4 can be easily fixed.

As described above, the bracing fixture 10 of the present embodiment is used.

For example, the vertical material contact plate portion and the horizontal member contact plate portion may be formed by bending a part of one metal plate as in the above embodiment, Another metal piece may be formed by welding or mechanically joining. In addition, the side edge 1 of the bracing fixture 10
2a and the side edge 13a are each linear,
Each may be curved or may have a single or multiple steps in the middle. The lower edge of the bracing abutment plate 11 connecting the side edge 12a and the side edge 13a is not only linear, but also has a curved shape or a shape having a single or a plurality of steps in the middle. Is also good.

Further, the vertical material abutting plate portion 12 and the horizontal member abutting plate portion 13 do not have to be symmetrical to each other. For example, the vertical material abutting plate may be attached in accordance with the mounting angle of the brace. The size and shape of the contact plate portion 12 and the horizontal member contact plate portion 13 may be changed. Further, the shape, dimensions, and the like of other parts can be appropriately set without departing from the spirit of the present invention.
