The present invention has the above configuration and has the following advantages and features.
アンカーボルトと鉄筋の兼用により、鉄骨部
分を包み込んだ鉄筋コンクリートの充填が容易
になり、断面寸法を小さくできる。 The dual use of anchor bolts and reinforcing bars makes it easier to fill the steel frame with reinforced concrete, making it possible to reduce cross-sectional dimensions.
鉄骨部分より鉄筋コンクリート部分の鉄筋へ
の応力の伝達が直接となり信頼性が向上する。 Stress is transmitted more directly to the reinforcing bars in the reinforced concrete part than in the steel frame part, improving reliability.
鉄骨建方時の高さ調整をナツトで容易にで
き、品質の向上が図れる。 The height of the steel frame can be easily adjusted using nuts, improving quality.
仮設用アンカーフレームが不要となる。 No need for temporary anchor frames.
アンカーをプレハブのフレームとすることに
より、アンカーボルト相互の誤差が極小とな
り、またアンカーボルトとしての付着性能が向
上する。 By using a prefabricated frame as the anchor, errors between the anchor bolts are minimized, and the adhesion performance of the anchor bolts is improved.
