PILE AND FOUNDATION JOINT METHOD AND PILE HEAD JOINT STRUCTURE
To provide a simple method for efficiently improving pull-out strength and bending resistance, in a pile head joint part for joining a pile head part to a foundation of a building.SOLUTION: A pile and foundation joint method for joining a pile head part and a foundation of a building includes the steps of: embedding the lower half of a pre-stress introduction member to which tension has been previously introduced to concrete placed to the pile side, and fixing the lower half thereof thereto; embedding the upper half of the pre-stress introduction member to the concrete constituting the foundation, together with a pile head reinforcement member projecting upward from the pile; and curing the concrete constituting the foundation, and then releasing the tension of the pre-stress introduction member.SELECTED DRAWING: Figure 1
【課題】杭頭部と建物の基礎とを接合する杭頭接合部において、効率よく引抜き耐力と曲げ耐力の向上を図る簡略な方法を提供する。【解決手段】杭頭部と建物の基礎とを接合する、杭と基礎の接合工法であって、あらかじめ張力が導入されたプレストレス導入部材の下半を、杭側に打設されるコンクリートに埋設し固定する工程と、前記プレストレス導入部材の上半を、前記杭から上方に突出する杭頭補強部材とともに前記基礎をなすコンクリートに埋設する工程と、該基礎をなすコンクリートが硬化したのち、前記プレストレス導入部材の張力を解放する工程と、を含む。【選択図】図１
