GROUT FORM AND COLUMN BASE

To provide a grout form which has achieved improvement in workability and to provide a column base.SOLUTION: A column base 1 includes: a column 2 for supporting a building; a column base foundation 3 for supporting the column 2; a base plate 4 mounted on the column 2, and connected to the foundation 3; a grout form 10 used when filling a grout material 6 in a gap of the base 3 and the base plate 4; and a column base cover member mounted on the foundation 3, and provided so as to cover a lower end part of the column 2, the base plate 4, and the grout form 10. The grout form 10 has a first member 11 and a second member 12 connected so as to surround the base plate 4. In the direction in which the first member 11 and the second member 12 are opposing to each other, a mounting claw provided in the first member 11 is detachably mounted with respect to a mounting hole provided at the second member 12, and the first member 11 is connected to the second member 12 with one part being overlapped.SELECTED DRAWING: Figure 2A 【課題】施工性の向上を図ったグラウト型枠及び柱脚を提供する。【解決手段】柱脚１は、建物を支持する柱２と、柱２を支持する柱脚基礎３と、柱２に取り付けられ、基礎３に連結されるベースプレート４と、基礎３及びベースプレート４の隙間にグラウト材６を充填する際に用いられるグラウト型枠１０と、基礎３上に取り付けられ、柱２の下端部、ベースプレート４及びグラウト型枠１０を覆うように設けられた柱脚カバー部材とを備えている。グラウト型枠１０は、ベースプレート４を囲むように連結される第１部材１１及び第２部材１２を有している。第１部材１１と第２部材１２が対向する方向において第１部材１１に設けられた取り付け爪が、第２部材１２に設けられた取り付け穴に対し着脱可能に取り付けられており、第１部材１１が第２部材１２と一部重なり合って連結されている。【選択図】図２Ａ
