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.

Claims (27)

1. 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 two sides movable with respect to the concrete product to separate the concrete form from the concrete product;

an actuator combined to each of the at least two sides of the concrete form and connected in parallel each for moving simultaneously one side of the at least two sides with respect to the concrete product; and

a power source combined to each actuator for driving each actuator for moving the at least two sides with respect to the concrete product.

2. The system of claim 1 , wherein the power source is a rotary driven power source.

3. The system of claim 2 , wherein the rotary driven power source is a rotary pump comprising of a transmission shaft for operating the rotary pump.

4. The system of claim 3 , and further comprising a rotary power tool combinable to the transmission shaft of the rotary pump for rotating the transmission shaft and operating the rotary pump.

5. The system of claim 4 , and further comprising:

a first adapter combinable to the rotary power tool 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 transmission shaft of the rotary pump for providing one-way rotation of the transmission shaft of the rotary pump to protect the pump.

6. The system of claim 5 , wherein the first adapter comprises a helical cutout to prevent the second adapter and the transmission shaft from being rotated in one direction.

7. 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 two sides each movable with respect to the concrete product to separate the concrete form from the concrete product;

an actuator combined to each of the at least two sides of the concrete form and connected in parallel each for moving simultaneously one side of the at least two sides with respect to the concrete product; and

a rotary driven power source combined to each actuator for driving each actuator for moving the at least two sides with respect to the concrete product.

8. The system of claim 7 , and further comprising a rotary power tool combinable to the rotary driven power source for rotating the rotary driven power source and operating the rotary driven power source.

9. The system of claim 8 , and further comprising:

a first adapter combinable to the rotary power tool 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 for providing one-way rotation of the rotary driven power source to protect the rotary driven power source.

10. The system of claim 9 , wherein the first adapter comprises a helical cutout to prevent the second adapter and the rotary driven power source from being rotated in one direction.

11. The system of claim 10 , wherein the first adapter comprises opposing flat faces to mate with the second adapter to rotate the second adapter.

12. The system of claim 11 , wherein the second adapter comprises opposing protruding lugs that are engaged by the opposing flat faces of the first adapter to rotate the second adapter.

13. A system for stripping concrete forms comprising at least one movable side from a concrete product, the system comprising:

a first adapter combinable to a rotary power tool 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, wherein when the rotary driven power source is combined to an actuator, the rotary driven power source drives the actuator for moving the at least one movable side with respect to the concrete product.

14. The system of claim 13 , wherein the second adapter comprises opposing protruding lugs that are engaged by the opposing flat faces of the first adapter to rotate the second adapter.

15. The system of claim 14 , and further comprising a rotary power tool combinable to the first adapter.
