PILE HEAD JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a pile head joint structure that can efficiently reinforce a joint part of a pile head part of a foundation pile and foundation concrete; and in which reinforcing bars made of materials with poor weldability can be used and the number of the reinforcing bars can be reduced; and that can achieve elimination of overcrowding arrangement of the reinforcing bars above the pile head.SOLUTION: A pile head joint structure 40 joining a foundation pile 44 and foundation concrete 48 integrally includes a plurality of joint members 42 to which lower ends of reinforcing bars 46 are joined. The plurality of joint members 42 are joined to an outer peripheral surface 44b of a pile head 44a such that they are spaced apart, and a length in a direction corresponding to a circumferential direction of the pile head 44a is longer than a length in a direction corresponding to a radial direction of the pile head 44a. Each of the joint members 42 is formed by a single solid member that has an upper surface substantially in parallel with an upper end surface of the pile head 44a and a lateral surface facing the outer peripheral surface 44b. On the upper surface of the joint member 42, a plurality of through holes into which the lower ends of the reinforcing bars 46 can be inserted are formed.SELECTED DRAWING: Figure 1
【課題】基礎杭の杭頭部と基礎コンクリートの接合部を効果的に補強することができ、かつ溶接性の悪い材料からなる補強鉄筋を用いることもできると共に、補強鉄筋の本数を減らすことができ、かつ杭頭部の上方における過密配筋の解消を図ることができる杭頭接合構造を提供する。【解決手段】基礎杭４４と基礎コンクリート４８を一体的に接合させる杭頭接合構造４０において、補強鉄筋４６の下端部が接合される複数の接合部材４２を備え、複数の接合部材４２は、杭頭部４４ａの外周面４４ｂに間隔をあけて接合されると共に、その杭頭部４４ａの円周方向に相当する方向の長さが、その杭頭部４４ａの径方向に相当する方向の長さよりも長く、接合部材４２のそれぞれは、杭頭部４４ａの上端面に略平行な上面と外周面４４ｂに対向する側面とを有する単一の中実部材により形成され、接合部材４２の上面には、補強鉄筋４６の下端部が挿通可能な貫通孔が複数形成された。【選択図】図１
