CONSTRUCTION METHOD OF CONCRETE-FILLED STEEL PIPE, CONCRETE-FILLED STEEL PIPE COLUMN, AND COLUMN MEMBER
To provide a construction method of a concrete-filled steel pipe which can construct without using an erecting facility such as a crane, a timbering, a jack and a hanging member, and which can reduce work time of assembly and efficiently construct by filling concrete concurrently with assembly.SOLUTION: A construction method of a concrete-filled steel pipe comprises: installing a plurality of steel pipes with different outer diameters in a nesting shape; and pushing up, when an arbitrary steel pipe except the outermost steel pipe among the steel pipes installed in the nesting shape is a steel pipe A, the steel pipe A by a filling pressure of concrete, until an outer diameter widened portion provided in the steel pipe A comes in contact with an inner diameter narrowed portion provided in a steel pipe installed at an outside of the steel pipe A by one.SELECTED DRAWING: Figure 5
【課題】コンクリート充填鋼管の施工方法において、クレーンや、支保工及びジャッキ、吊り材等の立上げ設備を用いることなく施工でき、また組立てと同時にコンクリートを充填していくことにより、組立ての作業時間を削減し、効率的な施工が可能なコンクリート充填鋼管の施工方法を提供すること。【解決手段】コンクリート充填鋼管の施工方法であって、外径の異なる複数の鋼管を入れ子状に設置し、前記入れ子状に設置した鋼管のうち最外の鋼管を除く任意の鋼管を鋼管Ａとしたとき、コンクリートの充填圧力により、当該鋼管Ａに設けた外径拡幅部と、当該鋼管Ａの１つ外側に設置した鋼管に設けた内径縮幅部とが接触するまで、当該鋼管Ａを押し上げることを特徴とするコンクリート充填鋼管の施工方法。【選択図】図５
