Abstract
A concrete form for holding a concrete product in place during a curing process with at least one side movable by a rotary driven power source and a actuator. A rotary power tool with a helical cutout combinable to a second adapter on the rotary driven power source to rotate the rotary driven power source to power the actuator and move the at least one side.
Claims15
A system for breaking a bond between a concrete form and a concrete product with a rotary power tool, wherein the concrete form holds the concrete product in place during a curing process, wherein the concrete form comprises of at least one portion movable with respect to the concrete product to break the bond between concrete product and the concrete form, the system comprising:
- an actuator combined to the concrete form for moving the at least one portion of the concrete form with respect to the concrete product;
- a rotary driven power source combined to the actuator for driving the actuator for moving the at least one portion of the concrete form with respect to the concrete product;
- a first adapter combinable to the rotary power tool, the first adapter comprising an outer surface, an inner surface, a top surface normal to an axis of rotation connecting the outer surface and the inner surface, two opposing flat faces that are each perpendicular to the axis of rotation and extend axially downward from the top surface and two helical cutouts each beginning at the bottom of a flat face of the two opposing flat faces and extending to the top surface;
- and
- a second adapter combinable to the rotary driven power source.
A system for stripping concrete forms from a concrete product, the system comprising:
- a concrete form for holding a concrete product in place during a curing process, wherein the concrete form comprises of at least one side movable with respect to the product to separate the concrete form from the product;
- an actuator combined to the concrete form for moving the at least one side with respect to the concrete product;
- and
- a rotary driven power source combined to the actuator for driving the actuator for moving the at least one side with respect to the concrete product;
- a second adapter combinable to the rotary driven power source;
- a first adapter combinable to the second adapter, the first adapter comprising an outer surface, an inner surface, a top surface normal to an axis of rotation connecting the outer surface and the inner surface, two opposing flat faces that are each perpendicular to the axis of rotation and extend axially downward from the top surface, and two helical cutouts each beginning at the bottom of a flat face of the two opposing flat faces and extending to the top surface, wherein the first adapter is drivable by a rotary power tool.
A system for breaking a bond between a concrete form and a concrete product that is at least partially cured in the concrete form using a rotary driven power tool, wherein the concrete form comprises at least one actuator for moving a portion of the concrete form with respect to the concrete product, the system comprising:
- a rotary driven power source combinable to the actuator for driving the actuator to move the portion of the concrete form with respect to the concrete product to break the bond between the concrete form and the concrete product;
- a first adapter combinable to a rotary power tool, the first adapter comprising an outer surface, an inner surface, a top surface normal to an axis of rotation connecting the outer surface and the inner surface, two opposing flat faces that are each perpendicular to the axis of rotation and extend axially downward from the top surface, and two helical cutouts each beginning at the bottom of a flat face of the two opposing flat faces and extending to the top surface;
- and
- a second adapter combinable to a rotary driven power source.
