The adjustment portion includes an attachment member, a first adjustment member, and a second adjustment member. The attachment member is inserted into an attachment hole of the formwork attachment portion and is engaged with a formwork so as to attach the formwork attachment portion to an outer surface of the formwork. The first adjustment member is disposed between the outer surface of the formwork and a back surface of the formwork attachment portion. The second adjustment member protrudes from the back surface of the formwork attachment portion toward the formwork, and engages with an adjustment hole of the formwork attachment portion to be able to adjust a protrusion amount toward the formwork.
1 . An anchor support that is configured to support an anchor provided in a foundation, the anchor support comprising:
a formwork attachment portion configured to be attached to an outer surface of a formwork of the foundation;
an anchor support portion extending from the formwork attachment portion and supporting the anchor; and
an adjustment portion that is configured to adjust at least one of a first angle in a vertical direction and a second angle in a horizontal direction of the anchor support portion with respect to the formwork, wherein
the formwork attachment portion includes an attachment hole and an adjustment hole, and
the adjustment portion includes:
an attachment member inserted into the attachment hole of the formwork attachment portion and configured to be engaged with the formwork to attach the formwork attachment portion to the outer surface of the formwork;
a first adjustment member disposed between the outer surface of the formwork and a back surface of the formwork attachment portion; and
a second adjustment member protruding from the back surface of the formwork attachment portion toward the formwork, and engaging with the adjustment hole of the formwork attachment portion to be able to adjust a protrusion amount toward the formwork.
2 . The anchor support according to claim 1 , wherein the first adjustment member includes an inclined surface inclined such that a thickness of the first adjustment member increases in a direction along the outer surface of the formwork, or multiple stepped surfaces in which the thickness of the first adjustment member increases in a direction along the outer surface of the formwork.
3 . The anchor support according to claim 1 , wherein
the adjustment hole includes a first adjustment hole, a second adjustment hole, and a third adjustment hole,
the adjustment portion includes three second adjustment member disposed in the first adjustment hole, the second adjustment hole, and the third adjustment hole, respectively,
the first adjustment hole is disposed above the second adjustment hole or the third adjustment hole in the vertical direction, and
the first adjustment hole is disposed at a position away from the second adjustment hole or the third adjustment hole in the horizontal direction.
4 . The anchor support according to claim 1 , further comprising a main body support portion provided on a lower surface of the anchor support portion to support the anchor support portion,
wherein the main body support portion is configured to be disposed on an upper surface of the formwork.
5 . The anchor support according to claim 1 , wherein
the formwork attachment portion includes an attachment plate-shaped member disposed to extend in the vertical direction along the formwork,
the anchor support portion includes an anchor support plate-shaped member intersecting the attachment plate-shaped member, and
the anchor support plate-shaped member is formed integrally with the attachment plate-shaped member.
6 . An anchor installation method of installing an anchor in a formwork by using an anchor support, the anchor support including a formwork attachment portion configured to be attached to an outer surface of the formwork of a foundation and an anchor support portion that supports the anchor, the anchor installation method comprising:
attaching the formwork attachment portion to the outer surface of the formwork by an attachment member such that a gap is provided between the outer surface of the formwork and a back surface of the formwork attachment portion;
disposing a first adjustment member in the gap; and
adjusting an angle of the anchor support portion with respect to the formwork by protruding a second adjustment member from the back surface of the formwork attachment portion toward the formwork, the second adjustment member being engaged with an adjustment hole provided in the formwork attachment portion, and by adjusting a protrusion amount toward the formwork.
