Abstract
A fixture for setting rebar at a predetermined distance from the rim of an excavated pit includes elongated first and second legs each having a proximal end and a distal end, the first and second legs rigidly joined at their mutual proximal ends to form an L-shape; an angle adjustment device carried by the first leg, comprising a foot movable towards or away from the first leg along an axis generally parallel to the second leg; a support bracket carried by the first leg at a predetermined offset distance from the proximal end thereof; and a hook extending from the distal end of the second leg, generally parallel to the first leg.
Claims15
A fixture for setting rebar at a predetermined distance from the rim of an excavated pit, comprising:
- elongated first and second legs each having a proximal end and a distal end, the first and second legs rigidly joined at their mutual proximal ends to form an L-shape;
- an angle adjustment device carried by the first leg, comprising a foot movable towards or away from the first leg along an axis generally parallel to the second leg;
- a support bracket carried by the first leg at a predetermined offset distance from the proximal end thereof;
- and
- a hook extending from the distal end of the second leg, generally parallel to the first leg.
A method for setting rebar at a predetermined distance from the rim of an excavated pit, comprising:
- placing a plurality of fixtures at spaced-apart locations around the rim of a pit excavated into the earth, the pit defined by a recessed floor bounded by a generally vertical perimeter wall and being surrounded by a rim, and wherein an upstanding form is disposed around the perimeter of the rim laterally offset from the perimeter wall, each fixture including:
- elongated first and second legs each having a proximal end and a distal end, the first and second legs rigidly joined at their mutual proximal ends to form an L-shape;
- an angle adjustment device carried by the first leg, comprising a foot movable towards or away from the first leg along an axis generally parallel to the second leg;
- a support bracket joined to the first leg at a predetermined offset distance from the proximal end thereof;
- and
- a hook extending from the distal end of the second leg, generally parallel to the first leg;
- positioning the hook of each of the fixtures in engagement with the form;
- adjusting each of the fixtures using the angle adjustment device so that the first leg is plumb;
- and
- placing a length of rebar into the pit, engaged with the support brackets of the plurality of fixtures, such that the rebar is positioned at a substantially uniform vertical offset distance from the rim.
