PILE HEAD SEMI-RIGID JOINT STRUCTURE
To provide a pile head semi-rigid joint structure which can reduce shear force transmitted to a pile head part from a foundation and flexural stress.SOLUTION: A pile head semi-rigid joint structure includes: a foundation 2 positioned below a structure; a pile body 3 which is penetrated into a ground G and is arranged so as to be separated from a lower end 21 of the foundation 2; a joint part 8 including a reinforcement steel pipe 4 surrounding the periphery of a pile head part 34 of the pile body 3, and a filling part 6 formed so as to fill the inside of the reinforcement steel pipe 4 with a filler 61; and an edge cutting part 5 which is arranged between the foundation 2 and the joint part 8, is brought into contact with the lower end 21 of the foundation 2 and an upper end part 81 of the joint part 8, and has a contact surface 512 formed so as to be larger than an upper end face 42 of the reinforcement steel pipe 4.SELECTED DRAWING: Figure 1
【課題】基礎から杭頭部に伝達されるせん断力および曲げ応力を小さくすることができる杭頭半剛接合構造を提供する。【解決手段】構造物の下方に位置する基礎２と、地盤Ｇに貫入され、基礎２の下端部２１から離れて配置された杭体３と、杭体３の杭頭部３４の周囲を包囲する補強鋼管４と、補強鋼管４の内部に充填材６１を充填して形成される充填部６と、を備える接合部８と、基礎２と接合部８との間に配置され、基礎２の下端部２１と接合部８の上端部８１に当接し、補強鋼管４の上端面４２より大きく形成された当接面５１２を備えた縁切り部５と、を備える。【選択図】図１
