Abstract
A column shoe assembly can include a shoe body that defines an internal cavity with a rear wall. A lower rod opening can open into the internal cavity and defines a connection axis. An access opening can open into the internal cavity on an opposite side of the connection axis from the rear wall. A thickened rim can extend along a perimeter of the access opening.
Claims20
A column shoe assembly comprising:
- a shoe body that defines:
- an internal cavity that is closed continuously around a rear side and at opposite lateral sides by a rear wall and side walls of the shoe body;
- a lower rod opening aligned to receive a first section of rod along a connection axis into the internal cavity;
- an upper wall that secures a second section of rod opposite the lower rod opening;
- an access opening that opens into the internal cavity at a front side of the shoe body, with a rim of the shoe body extending around the access opening,
- the rim, as measured along a cross section perpendicular to the connection axis, having a first material thickness that is larger, at a location between the connection axis and the access opening, than a second material thickness of the shoe body along the rear wall.

A column shoe assembly comprising:
- a column shoe, including a shoe body that is integrally formed and defines:
- an internal cavity with a rear wall;
- a lower rod opening that opens into the internal cavity and defines a connection axis;
- a front access opening into the internal cavity on an opposite side of the connection axis from the rear wall;
- and
- a thickened rim extending along a perimeter of the front access opening;
- a first section of rod extending through the lower rod opening along the connection axis, the first section of rod being threadedly secured within the internal cavity with a threaded fastener that is fully within the internal cavity and accessible via the front access opening for threaded adjustment along the first section of rod;
- and
- a second section of rod secured to an upper side of the shoe body to extend away from the column shoe opposite the lower rod opening.

A method of connecting concrete sections, the method comprising:
- providing a first concrete section with a first threaded rod protruding from an end of the first concrete section;
- providing a second concrete section with a column shoe assembly embedded therein, the column shoe assembly including:
- a column shoe with a shoe body that includes an internal cavity with a rear wall, a lower opening that opens into the internal cavity, a front access opening into the internal cavity on an opposite side of a connection axis from the rear wall, and a thickened rim extending along a perimeter of the front access opening;
- and
- a second rod secured to an upper side of the shoe body, opposite the lower opening, and extending from the column shoe within the second concrete section;
- aligning the first and second concrete sections to insert the first threaded rod through the lower opening, along the connection axis, into the internal cavity of the column shoe;
- and
- threadedly securing the first threaded rod within the internal cavity by accessing the first threaded rod within the internal cavity via the front access opening.
