PRE-STRESSED CONCRETE PILE
To provide a pre-stressed concrete pile which can be easily manufactured and easily constructed without requiring a chipping work of an axial reinforcement.SOLUTION: A concrete portion 3 to be removed is provided at one side in an axial direction of a pile main body portion 2 formed of pre-stressed concrete. A partition back plate 4 having a larger diameter than that of the pile main body portion 2 is provided at a boundary portion of the pile main body portion 2 and the concrete portion 3 to be removed. A plurality of tendon steel materials 6 are arranged inside the pile main body portion 2, and its one end portion is fixed to the partition back plate 4. An axial reinforcement 7 is arranged from at least a part of the pile main body portion 2 to the concrete portion 3 to be removed.SELECTED DRAWING: Figure 1
【課題】容易に製造できるとともに、軸方向鉄筋のはつり出し作業が不要で容易に施工できるプレストレストコンクリート杭を提供する。【解決手段】プレストレストコンクリートで成形された杭本体部２の軸方向の一方側に除去予定コンクリート部３を設ける。また、杭本体部２と除去予定コンクリート部３との境界部分に、杭本体部２より外径が大きい仕切座板４を設ける。杭本体部２内に複数の緊張鋼材６を配設し、その一端部を仕切座板４に固定する。また、杭本体部２の少なくとも一部から除去予定コンクリート部３にわたって軸方向鉄筋７を配設する。【選択図】図１
