Are fixed at right angles to a crossbar fixing part 2 having a plurality of (two) nail holes 2a and a plurality (two of them) of bolt holes 2b. At the side edge, a bracing fixing part 3 having a plurality of (six in the figure) nail holes 3a and one (sometimes two or more) bolt holes 3b is attached to the pillar fixing part 1. And the column fixing part 2 and the column fixing part 2 are provided at right angles to each other and are connected to each other.

As shown in FIG. 4 and FIG. 5, the seismic reinforcement metal A for column bracing has the column fixing portion 1 on the side surface of the column 5, and the crossbar fixing portion 2 on the top surface of the base (crossbar) 6. Then, the fixing members 3 for the bracing are brought into contact with the bracing 7, respectively, and the bolts 11, 12, 13 are inserted through the bolt holes 1b, 2b, 3b of the fixing portions 1, 2, 3, respectively. The nail 9 is driven into the pillar 5, the base 6, and the brace 7 from the nail holes 1a, 2a, 3a of the fixing portions 1, 2, 3, respectively, and the nuts 11a, 12a, 13a are screwed respectively, and the columns 5 and the base 6 and the bracing 7 are attached together by being tightly connected.

The bolts 12 are generally known lag screw bolts, but may be anchor bolts embedded in the concrete foundation 15 in advance. The seismic retrofitting A on the right side of the column 5 in FIG. 4 is in the first and third bolt holes 1b from above in FIG. 1 of the column fixing portion 1, and the seismic retrofitting A on the left is in the second from the top. The bolt 11 is inserted through the fourth bolt hole 1b.

Reference numeral 17 denotes a seismic isolation washer, which is mounted between the nut 12a and an auxiliary seismic reinforcing metal described later. As shown in FIG. 7, this seismic isolation washer 17 is composed of a metal washer 17a integrally provided with a round washer 17a made of metal or the like, and absorbs an external force such as an earthquake by the elasticity of the seismic isolation rubber 17b. It has a structure to obtain a restoring force.

As shown in FIG. 6, the post-brace seismic retrofitting metal A is also used for integrally connecting the column fixing portion 5 to the trunk difference (crossbar) 8 and the brace 7. In this case, the fixing part 2 for the rung of the seismic reinforcement metal A is brought into contact with the upper surface or the lower surface of the stud 8, and is attached to the stud 8 with a nail 9 and a normal bolt (including a lug screw bolt) 18 and a nut 18a. In addition, the column fixing portion 1 (hidden on the opposite side of the column 5 in FIG. 6) and the bracing fixing portion 3 are brought into contact with the side surface of the column 5 and the bracing 7 to obtain the case shown in FIGS. Similarly, the nail 5 is attached to the column 5 and the brace 7 with the bolts 11 and 13 and the nuts 11a and 13a.

The nuts 25a and 26a are screwed into the bolts 26, respectively, and the nails 9 are driven into the base 6 from the nail holes 21a. It is attached to the body and attached.

In this aseismic strengthening structure, the reinforced aseismic strengthening hardware B prevents the base 6 from rising and laterally offset from the concrete foundation 15. Therefore, seismic resistance and durability are further improved.

As the bolt 26, a lag screw bolt other than a normal bolt can be used. As the anchor 25, a resin adhesive anchor, a mechanically driven all anchor, an embedded anchor, or the like can be used. In the case of the resin adhesive anchor 25, a pilot hole is made in the concrete foundation 15 with a concrete drill, an adhesive capsule is buried therein, and the anchor 25 is driven with an electric hammer drill or the like. In general, drill holes for concrete screws are also made with concrete drills.

In a state where the concrete screw 15 is brought into contact with the side surface of the base 6, the concrete screw 24 is screwed into the concrete foundation 15 from the screw hole 31 c, and the nut 25 a is screwed into the all anchor 25 inserted into the anchor hole 31 d. The nail 9 is driven into the base 6 through the nail holes 31a and 32a, and the nails 9 are attached to the concrete foundation 15 and the base 6 by being integrally tightened.

Also in this seismic retrofit structure, the base seismic retrofitting hardware C prevents the base 6 from rising and laterally offset with respect to the concrete foundation 15, so that the seismic resistance and durability are further improved. The seismic retrofitting C for the base can be used alone to compensate for the lack of anchor bolts, regardless of whether the seismic retrofitting A for column bracing or the auxiliary seismic retrofitting B is used.

Although the pillar 5 in the figure is a corner pillar that is susceptible to falling, the present invention can be applied to other pillars. 4 to 6, the nails 9 and the concrete screws 24 are shown in numbers less than the number of the nail holes 1a, 2a, 3a, 21a, 31a, 32a and the screw holes 21c, 31c. The same number or a number close to it is used.
