と鉄骨柱建込み精度を悪化する。The beam construction method in the conventional prior column main fastening method described above is such that a bolt hole is pre-drilled in a factory at a design dimension position in a beam joint portion of a steel frame column, a steel frame beam and a splice plate. However, the drilled bolt holes are matched at the site. Therefore, the bolt hole position may be different due to manufacturing error of the steel frame column and the steel frame beam or the installation accuracy of the steel frame column. In such a case, if the reamer is hooked up on site to match the bolt hole positions, it will be dangerous because the work will be done at a high place. Further, if the bolt hole positions are forcibly matched with each other, the steel frame column installation accuracy is deteriorated.
