Abstract
A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other and a cross tie having opposed first and second ends, where at least the first sidewall is a removable sidewall removably secured to the first end of the cross tie. The second sidewall is removably secured to the second end of the cross tie and may be a removable sidewall or a non-removable sidewall. The concrete form also includes a spacer positioned between the first sidewall and the first end of the cross tie. The spacer may be removable along with the first sidewall. Concrete forming assemblies and methods may incorporate concrete forms as described herein.
Claims20
A concrete form comprising:
- a first sidewall and a second sidewall positioned in parallel and spaced relation to each other to define a cavity, with inner surfaces of the first and second sidewalls facing the cavity;
- a cross tie having opposed first and second ends and having first and second flat securement plates on the first end, wherein the first sidewall is removably secured to the first end of the cross tie by first and second removable fasteners extending through the first sidewall and embedded in the first and second securement plates, respectively, and the second sidewall is secured to the second end of the cross tie;
- and
- first and second spacers positioned between the first sidewall and the first end of the cross tie to define a space between the first sidewall and the cross tie, wherein the first and second spacers are connected to the first sidewall and removably connected to the cross tie by the first and second fasteners, such that the first and second fasteners extend through the first and second spacers, respectively,
- wherein each of the first and second spacers has a first side engaging the inner surface of the first sidewall and a second side opposite the first side, the second side of the first and second spacers engaging the first and second securement plates, respectively, and wherein the first securement plate has a larger area than the second side of the first spacer, and the second securement plate has a larger area than the second side of the second spacer, and
- wherein the concrete form is configured for use in forming a concrete structure within the cavity by introducing concrete into the cavity and allowing the concrete to solidify.

An assembly comprising:
- a first concrete form comprising:
- a first sidewall and a second sidewall positioned in parallel and spaced relation to each other to define a first cavity, with inner surfaces of the first and second sidewalls facing the first cavity;
- a first cross tie having opposed first and second ends and having a flat securement plate on the first end, wherein the first sidewall is removably secured to the first end of the first cross tie by a removable fastener extending through the first sidewall and embedded in the securement plate, and the second sidewall is secured to the second end of the first cross tie;
- and
- a spacer positioned between the first sidewall and the first end of the first cross tie to define a space between the first sidewall and the first cross tie, wherein the spacer is connected to the first sidewall and removably connected to the first cross tie by the fastener, such that the fastener extends through the spacer,
- wherein the spacer has a first side engaging the inner surface of the first sidewall and a second side opposite the first side, the second side of the spacer engaging the securement plate, and wherein the securement plate has a larger area than the second side of the spacer;
- and
- a second concrete form comprising:
- a third sidewall and a fourth sidewall positioned in parallel and spaced relation to each other to define a second cavity, with inner surfaces of the third and fourth sidewalls facing the second cavity;
- and
- a second cross tie having opposed first and second ends, wherein the third sidewall is secured to the first end of the second cross tie, and the fourth sidewall is secured to the second end of the second cross tie,
- wherein the first concrete form is stacked upon the second concrete form such that the first and second cavities are continuous with each other, and wherein the assembly is configured for use in forming a concrete structure by introducing concrete into the first and second cavities and allowing the concrete to solidify.
