PILE HEAD CAP AND BUILDING FOUNDATION

To provide a pile head cap and a foundation structure for which on-site work such as welding steel plates for pile heads is not required.SOLUTION: A pile head cap 1 comprises: a steel plate part 11; and a plurality of protrusions 12 that protrude downward from the bottom surface of the steel plate part 11, and that face the inner circumferential surface of a pile head 51 on the upper edge side while the pile head 51 of a steel pipe pile 5 is covered with the pile head cap 1 from above. On the bottom surface of the steel plate part 11, a rib part 13 that is connected to the protrusions 12 to improves the rigidity and strength of the steel plate part 11 is provided.SELECTED DRAWING: Figure 1 【課題】現場での杭頭への鉄板溶接といった作業を不要にできる杭頭キャップおよび基礎構造を提供する。【解決手段】杭頭キャップ１は、鋼鉄板部１１と、上記鉄板部１１の下面側から下方に突出し、上記鋼管杭５の杭頭５１に上から被せられた状態で上記杭頭５１の上縁側の内周面に対向する複数の突出部１２と、を備える。また、上記鉄板部１１の下面には、上記突出部１２に接続されて上記鉄板部１の剛性や強度を向上させるリブ部１３が設けられている。【選択図】図１
