COLUMN BASE FIXING STRUCTURE AND COLUMN BASE FIXING METHOD
PROBLEM TO BE SOLVED: To provide a column base fixing structure capable of increasing pull-out strength while preventing upsizing of a concrete foundation, and a column base fixing method.SOLUTION: An anchor member 3 comprises an anchor bolt 31 that is provided to be capable of rotating on its axis, and an auxiliary member 32 that is eccentrically provided. Thus, pull-out strength can be increased by increasing an area of contact with a grout material 4; a clearance between the anchor member 3 and a hole part 2A can be secured; and upsizing of a concrete foundation G can be prevented because enlargement of a diameter of the hole part 2A becomes unnecessary.
【課題】コンクリート基礎の大型化を防ぎつつ引き抜き耐力を向上させることができる柱脚固定構造及び柱脚固定方法を提供すること。【解決手段】アンカー部材３が軸周りに回転自在に設けられたアンカーボルト３１と、偏心して設けられた副部材３２と、を備えていることで、グラウト材４との接触面積を大きくして引き抜き耐力を向上させることができるとともに、アンカー部材３と穴部２Ａとのクリアランスを確保することができ、穴部２Ａを大径化する必要がなく、コンクリート基礎Ｇが大型化することを防止することができる。【選択図】図３
