ボルト設置精度及び作業効率の向上が期待できる。As described above, according to the present invention, since the exposed fixed column base is made of precast concrete which has been factory-produced in advance, the cast-in-place concrete casting formwork is unnecessary, and the cast-in-place concrete and the in-situ rebar are not required. The construction period can be shortened, for example, it is unnecessary, and cost reduction can be expected. In addition, the use of dimensional adjustment pedestals to fix the anchor bolts eliminates the need for adjustment washers, which was necessary with conventional exposed fixed column bases, and the displacement of anchor bolts that occurred during concrete casting. Can be prevented, and an improvement in anchor bolt installation accuracy and work efficiency can be expected.
