SHAPED STEEL PILE BEARING BUILDING, AND METHOD FOR IMPLANTING SHAPED STEEL PILE
PROBLEM TO BE SOLVED: To provide a shaped steel pile and a method for implanting the shaped steel pile that can be implanted to a defined depth easily and that is superior in bearing capacity compared with a conventional one.SOLUTION: This invention is a method for implanting a shaped steel pile 1 bearing a building. In the shaped steel pile 1, a closed pile region 20 and an opening pile region 30 are arranged contiguously in a laterally cross-sectional direction. The closed pile region 20, in which a hollow part is formed within the interior surrounded by a sidewall, is surrounded by a first sidewall having the shape of C in a view from the laterally cross-sectional direction, and the opening pile region 30, which is formed between a pair of second sidewalls facing each other that extend from both ends of the first sidewall, includes a lateral opening 30a formed between the tip edges of the second sidewalls. When the pile head of the shaped steel pile 1 is struck during implantation of the shaped steel pile 1, the second sidewalls are deformed so that the width of the opening pile region 30 is expanded, and the shaped steel pile 1 is implanted in a ground by the pressure of earth charged in the closed pile region 20 and the opening pile region 30 via a tip opening formed on the tip of the shaped steel pile in a longitudinal direction.SELECTED DRAWING: Figure 2
【課題】規定深さまで打ち込むことが容易で、且つ、従来に比べて支持力の優れた形鋼杭及びその打ち込み方法を提供する。【解決手段】建造物を支持する形鋼杭１の打ち込み方法であって、形鋼杭１は、側壁によって囲まれた内側に中空部が形成されると共に、横断面方向視がＣ形状を有する第１側壁によって囲まれた閉塞杭領域２０と、第１側壁の両端から延設される一対の対向する第２側壁間に形成される開放杭領域３０であって第２側壁の先端縁間に形成される側方開口部３０aを含む開放杭領域３０が横断面方向に連設され、形鋼杭１の打ち込み時に形鋼杭１の杭頭を打撃した際、その長手方向の先端に形成された先端開口を通じて閉塞杭領域２０及び開放杭領域３０に充填された土圧によって、開放杭領域３０を拡幅するように第２側壁を変形させつつ形鋼杭１を地盤に打ち込む。【選択図】図２
