PILE HEAD REINFORCEMENT MEMBER AND PILE HEAD REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a pile head reinforcement member and a pile head reinforcement structure capable of: securing sufficient stress conveyance capability between a pile and a foundation and sufficient fastening force to a pile head part; reducing a possibility of interference with a reinforcing bar embedded in the foundation; and enhancing construction work quality around the pile head part by reducing a number of welding processes and securing appropriate structural strength, as the reinforcement structure and a constituent member used therewith.SOLUTION: A pile head reinforcement member 1 is for conveying force exerted on a pile head 2a between a pile 2 and a foundation, and includes: a plate-form material 4 provided in a vertical direction laterally on an outer peripheral surface 2c of the pile head part and embedded in foundation concrete CB that constitutes the foundation; a bar steel 5 inserted inward into the pile head part and fastened to the pile head part through pile concrete CP filled in the pile; a through-hole 11 formed to pierce through the plate-form material in a lateral direction; and a protrusion 12 protruded from a plate surface of the plate-form material, around the through-hole. The plate-form material and the bar steel are provided such that stress may be conveyed therebetween.SELECTED DRAWING: Figure 4
【課題】杭と基礎の間の応力伝達作用及び杭頭部に対する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、補強構造としても、それに用いる構成部品としても、溶接工数を削減することで杭頭部周りの施工上の品質を向上することが可能で、構造強度を適切に確保できる杭頭補強部材及び杭頭補強構造を提供する。【解決手段】杭２と基礎との間で杭頭部２ａに作用する力を伝達するための杭頭補強部材１であって、杭頭部の外周面２ｃ側方に縦向きで設けられ、基礎を構築する基礎コンクリートＣＢ中に埋設するための板状材４と、杭頭部内方に挿入され、杭内方に充填される杭コンクリートＣＰを介して杭頭部に定着させるための棒鋼５と、板状材に横向きに貫通形成された貫通孔１１と、板状材にその板面から貫通孔周りに突設された突出部１２とを備え、板状材と棒鋼とは相互に応力伝達可能に設けられている。【選択図】図４
