Abstract

A pavement dowel bar assembly is reinforced to maintain the alignment of dowel bars during the paving process. An exemplary dowel bar assembly includes a side frame having at least one bracing member. The bracing member is convertible between a first, stored position and a second, deployed position. When in the first, stored position, the bracing member is generally parallel to a plane defined by the side frame. In the second, deployed position, the bracing member is at an angle relative to the plane of the side frame. The dowel bar assembly may further include a plurality of dowel bars and a second side frame. Also described herein are methods of reinforcing a pavement dowel bar assembly with a convertible bracing member.

Claims

1. A concrete pavement dowel bar assembly comprising:

a side frame including at least one bracing member, said side frame further comprising;

a first connector defining a support for a first dowel bar;

a second connector defining a support for a second dowel bar;

a first cross member joining the first connector with the second connector;

a second cross member spaced apart from the first cross member, the second cross member joining the first connector with the second connector, the space between the first and second cross members defining the plane of the side frame; and

said at least one bracing member being convertible between a first, stored position and a second, deployed position, wherein when in the stored position, the at least one bracing member is generally parallel to a plane defined by the side frame, and when in the second, deployed position, the at least one bracing member is disposed at an angle relative to the plane of the side frame.

2. The assembly of claim 1, wherein the at least one bracing member further comprises a first end portion coupled to at least one of the first cross member or the first connector, a second end portion coupled to at least one of the second cross member and the first connector, and an intermediate portion extending between the first end portion and the second end portion, wherein the intermediate portion is convertible between the stored first position and the deployed second position.

3. The assembly of claim 1, further comprising a first dowel bar and a second dowel bar, each of the first and second dowel bars having an end portion coupled to the side frame.

4. The assembly of claim 3, wherein each of the first dowel bar and the second dowel bar has a midpoint generally halfway between a first end portion and a second end portion of the dowel bar and the at least one bracing member does not extend beyond the dowel bar midpoint when in the second, deployed position.

5. The assembly of claim 2, wherein the intermediate portion further comprises a first arm extending from the first end portion that converges with a second arm extending from the second end portion.

6. The assembly of claim 5, further comprising a brace stiffener coupled to at least one of the first arm or second arm.

7. The assembly of claim 1, further comprising a second side frame.

8. The assembly of claim 1, wherein the at least one bracing member further comprises an end portion coupled to at least one of the first cross member or the first connector, and an arm extending from the end portion, wherein the arm is convertible between the stored first position and the deployed second position.

9. The assembly of claim 8, further including a brace stiffener coupled to the arm.

10. The assembly of claim 1, wherein the at least one bracing member includes an arm extending from at least one of the first cross members or the second cross member.

11. The assembly of claim 10, wherein the at least one bracing member includes a brace stiffener coupled to the arm.

12. A concrete pavement dowel bar assembly comprising:

a side frame including at least one bracing member, said side frame further comprising;

a first connector defining a support for a first dowel bar;

a second connector spaced apart from the first connector, the second connector defining a support for a second dowel bar, and the space between the first and second connectors defining the plane of the side frame;

a cross member joining the first connector with the second connector; and

said at least one bracing member being convertible between a first, stored position and a second, deployed position, wherein when in the stored position, the at least one bracing member is generally parallel to a plane defined by the side frame, and when in the second, deployed position, the at least one bracing member is disposed at an angle relative to the plane of the side frame.

13. The assembly of claim 12, wherein the at least one bracing member further comprises a first end portion coupled to the first connector, a second end portion coupled to at least one of the cross member or the first connector, and an intermediate portion extending between the first and second end portions, wherein intermediate portion is convertible between the stored first position and the deployed second position.

14. The assembly of claim 12, further comprising a first dowel bar and a second dowel bar, each of the first and second dowel bars having an end portion coupled to the side frame.

15. The assembly of claim 14, wherein each of the first dowel bar and the second dowel bar has a midpoint generally halfway between a first end portion and a second end portion of the dowel bar and the at least one bracing member does not extend beyond the dowel bar midpoint when in the second, deployed position.

16. The assembly of claim 12, wherein the intermediate portion further comprises a first arm extending from the first end portion that converges with a second arm extending from the second end portion.

17. The assembly of claim 16, further comprising a brace stiffener coupled to at least one of the first arm or second arm.

18. The assembly of claim 12, further comprising a second side frame.

19. A method of reinforcing a concrete pavement dowel bar assembly, the method comprising:

providing a side frame for the concrete pavement dowel bar assembly, the side frame having a plurality of connectors for connecting to a plurality of dowel bars, a cross member joining the plurality of connectors, and at least one bracing member convertible between a first, stored position and a second, deployed position;

converting the at least one bracing member to the second, deployed position from the first, stored position, wherein when in the stored position, the at least one bracing member is generally parallel to a plane defined by the side frame, and when in the second, deployed position, the at least one bracing member is disposed at an angle relative to the plane of the side frame.

20. The method of claim 19, wherein the at least one bracing member is converted to the deployed position by bending an intermediate portion of the at least one bracing member such that said intermediate portion is configured to contact a support surface.
