PILE HEAD PIN JOINING STRUCTURE
PROBLEM TO BE SOLVED: To provide a pile head pin joining structure capable of easily reducing flexural stress caused in a joining part between a foundation pile and an upper structure, without using special material and construction method, while reducing a member cross section of the foundation pile and the upper structure.SOLUTION: A pile head pin joining structure 1 is arranged between a foundation pile 2 buried in an underground part of a building and an upper structure 3, and comprises a composite spring mechanism 6 composed of a shaft material part 4 for exhibiting shear capacity and a coil spring part 5 for reducing axial rigidity, and the shaft material part 4 of the composite spring mechanism 6 is inserted and arranged into a pile head part 7 of the foundation pile 2, and the coil spring part 5 of the composite spring mechanism 6 is inserted and arranged into a space 11 inside of a column of the upper structure 3 via a through-hole 10 of a baseplate 9 provided on the column lower end 8 of the upper structure 3, and the foundation pile 2 and the upper structure 3 are joined.
【課題】基礎杭と上部構造物の部材断面を縮小しながら、特殊な材料や施工方法を用いることなく簡便に、基礎杭と上部構造物との接合部分に生じる曲げ応力を小さくすることのできる杭頭ピン接合構造を提供すること。【解決手段】建物の地中部に埋設された基礎杭２と上部構造物３との間に配設する杭頭ピン接合構造１であって、せん断耐力を発揮する軸材部４と軸剛性を低下させるコイルばね部５とからなる複合ばね機構６を備え、複合ばね機構６の軸材部４が基礎杭２の杭頭部７に挿入配置され、複合ばね機構６のコイルばね部５が上部構造物３の柱下端８に設けられたベース板９の貫通孔１０を介して上部構造物３の柱内部の空間１１に挿入配置されて、基礎杭２と上部構造物３とが接合されていることを特徴とする。【選択図】図１
