PILE HEAD JOINT STRUCTURE, EARTHQUAKE PROOF REINFORCEMENT METHOD OF EXISTING STRUCTURE, AND REPAIR METHOD OF PILE HEAD JOINT PORTION OF EXISTING STRUCTURE
To easily change an energy absorbing member.SOLUTION: In a pile head joint structure for joining a foundation 3 of an upper structure with a main pile 2, a connection portion of the foundation 3 and the main pile 2 is joined by a semi-rigid joining which partially allows rotation of the foundation 3. The pile head joint structure comprises: an outer pipe pile 4 disposed coaxially with the main pile 2 so as to surround the main pile 2; a flat plate energy absorbing member 5 connected to a radially outer side of the outer pipe pile 4; and a ring-shaped receiving member 6 fastened to the foundation 3 and connecting the flat plate energy absorbing member 5 to the foundation 3.SELECTED DRAWING: Figure 1
【課題】エネルギー吸収部材の交換を容易に行うことができる。【解決手段】上部構造物の基礎３と本杭２を接続するための杭頭接合構造であって、基礎３と本杭２の接続部は、基礎３の回転を一部許容する半剛接合により接合され、本杭２の周囲を取り囲むように本杭２と同軸に配置された外管杭４と、外管杭４の径方向外側に接続された平板エネルギー吸収部材５と、基礎３に定着され、平板エネルギー吸収部材５を基礎３に接続するリング状受け部材６と、を備えた構成の杭頭接合構造を提供する。【選択図】図１
