FOUNDATION OF SUPPORT POST
PROBLEM TO BE SOLVED: To provide a foundation of a support post that resists tensile force exerted in a direction to pull out a spiral pile, especially to a swinging direction of the support post.SOLUTION: A foundation of a support post includes a base plate 4 provided at a bottom end of a support post 3, a plurality of long holes formed through the base plate 4, and a spiral pile formed by spirally twisting a flat steel material, and inserted into the long hole and screwed into a ground. The long hole is roughly orthogonal to a swinging direction of the support post 3 when seen in a planar view, and provided at one or more locations each on both sides of a line of swing passing through the support post 3. An angle of the long hole in a longitudinal direction is between 45° and 135° to the line of swing.SELECTED DRAWING: Figure 3
【課題】スパイラル杭を引く抜く方向に作用する引張力に対して特に支柱の揺動方向に応じて対抗することが可能な支柱基礎を提供する。【解決手段】支柱３の下端に設けられたベースプレート４と、ベースプレート４に形成された複数の長孔と、平鋼からスパイラル状に捻じられてなると共に長孔に差し込まれて地中に捻じ込まれるスパイラル杭とを備え、長孔は、平面視で支柱３の揺動し得る方向に対して略直交すると共に支柱３を通過する揺動ラインの両側にそれぞれ１箇所以上に亘り設けられ、その長手方向の角度は、揺動ラインに対して４５°以上１３５°以下であることを特徴とする。【選択図】図３
