PILE HEAD REINFORCEMENT STRUCTURE
To provide a pile head reinforcement structure which can sufficiently secure a stress transfer action and a fixing force, can reduce possibility such as to cause interference with bar arrangement buried in the foundation, facilitates a work of providing the pile head part so as to transfer the stress, and can appropriately secure a structural strength.SOLUTION: A pile head reinforcement structure has a pile head reinforcement member 3 whose an upper side is buried in the foundation in order to transmit a force acting on a pile head part 1a between a pile 1 and foundation 2 and a lower side is provided so as to transfer a stress to a steel-made portion of the pile head part, in which the pile head reinforcement member has a lateral plate-like portion 3h striding right above the pile head part, the lateral plate-like portion connects vertical plate-like portions 3a arranged on both sides of the pile head part, in the pile head reinforcement member, the lateral plate-like portion is joined to the pile head part to transfer a stress with the steel-made portion of the pile head part, and a through hole 3b penetrating the vertical plate-like portion in a lateral direction and a projection part 3d projecting from the surface of the vertical plate-like portion are provided.SELECTED DRAWING: Figure 9
【課題】応力伝達作用及び定着力を十分に確保することが可能であって、基礎中に埋設される配筋と干渉が生じるおそれを低減できると共に、杭頭部に対して応力伝達可能に設ける作業を容易化することが可能で、構造強度を適切に確保できる杭頭補強構造を提供する。【解決手段】杭１と基礎２との間で杭頭部１ａに作用する力を伝達するために、基礎中に上部側が埋設されると共に、下部側が杭頭部の鋼製部分と応力伝達可能に設けられる杭頭補強部材３を有する杭頭補強構造であって、杭頭補強部材は、杭頭部の直上を跨ぐ横向き板状部分３ｈを備え、横向き板状部分は、杭頭部の両側に配置される上下方向縦向き板状部分３ａを連結し、杭頭補強部材は、横向き板状部分が杭頭部に接合されて杭頭部の鋼製部分との間で応力伝達すると共に、上下方向縦向き板状部分を横向きに貫通する貫通孔３ｂと、上下方向縦向き板状部分の表面から突設される突出部３ｄとを備える。【選択図】図９
