Abstract

A bridge overhang bracket assembly includes a top member having an upper surface. The top member and a diagonal member are pivotally attached proximate to respective distal and upper ends thereof. The diagonal member and a side member are pivotally attached proximate to respective lower and bottom ends thereof. A connection element is mounted to the top member and is pivotally attached to a top end of the side member. The connection element is translatable along the top member to adjust a longitudinal position of the connection element relative to the top member. The connection element does not extend above the upper surface of the top member.

Claims

1. A bridge overhang bracket assembly, comprising:

a top member extending lengthwise between a proximal end and a distal end, the top member comprising an upper surface;

a diagonal member extending lengthwise between a lower end and an upper end, the top member and the diagonal member being pivotally attached proximate to the respective distal and upper ends thereof;

a side member extending lengthwise between a bottom end and a top end, the diagonal member and the side member being pivotally attached proximate to the respective lower and bottom ends thereof; and

a connection element mounted to the top member and pivotally attached to the top end of the side member, the connection element translatable along the top member for adjusting a longitudinal position of the connection element relative to the top member between the proximal and distal ends thereof,

wherein the connection element does not extend above the upper surface of the top member.

2. The assembly of claim 1, wherein the connection element is generally flush with the upper surface of the top member.

3. The assembly of claim 2, wherein the connection element does not extend below a lower surface of the top member.

4. The assembly of claim 3, wherein the connection element is generally flush with the lower surface of the top member.

5. The assembly of claim 1, wherein the top member comprises first and second channel members, each extending lengthwise between the proximal and distal ends of the top member, an inner surface of the first channel member facing and spaced laterally from an inner surface of the second channel member to define a slot, and the connection element is disposed within the slot.

6. The assembly of claim 5, wherein the connection element comprises first and second plates, an outer surface of the first plate arranged to engage the inner surface of the first channel member, and an outer surface of the second plate arranged to engage the inner surface of the second channel member.

7. The assembly of claim 6, wherein the connection element comprises:

a plurality of bores extending between and generally orthogonal to the first and second plates; and

a first pivot pin received in one of the plurality of bores in sliding fit between the outer surfaces of the first and second plates, the side member being pivotally attached to the first pivot pin.

8. The assembly of claim 7, wherein the first pivot pin comprises a first passage for receiving the side member.

9. The assembly of claim 8, wherein the side member comprises a threaded rod, and the first passage of the first pivot pin comprises a thread engaging element for engaging the threaded rod of the side member, such that rotation of the threaded rod about its axis causes the first pivot pin to move along an axial length of the side member.

10. The assembly of claim 7, comprising a tie bar, and the connection element comprises a second pivot pin received in one of the plurality of bores in sliding fit between the outer surfaces of the first and second plates, the tie bar being pivotally attached to the second pivot pin.

11. The assembly of claim 10, wherein the second pivot pin comprises a second passage for receiving the tie bar, and the second passage is laterally offset relative to the first passage of the first pivot pin.

12. The assembly of claim 11, wherein the tie bar comprises a threaded rod, and the second passage of the second pivot pin comprises a thread engaging element for engaging the threaded rod of the tie bar, such that rotation of the threaded rod about its axis causes the second pivot pin to move along an axial length of the tie bar.

13. The assembly of claim 6, wherein the connection element comprises at least one aperture extending between the first and second plates, the at least one aperture for receiving a respective at least one bolt to fix the longitudinal position of the connection element relative to the top member.

14. The assembly of claim 13, wherein each of the first and second channel members comprises a plurality of holes arranged between the proximal and distal ends, the plurality of holes permitting a plurality of fixed positions of the connection element along the top member.

15. The assembly of claim 14, wherein at least a portion of the plurality of holes are aligned horizontally along the first and second channel members.

16. The assembly of claim 15, wherein at least a portion of the plurality of holes are offset vertically from others of the plurality of holes.

17. The assembly of claim 1, wherein the diagonal member comprises at least one connection tab arranged intermediate the upper and lower ends, the connection tab for receiving a bolt to connect the top and diagonal members together in a shipping/storage position.

18. The assembly of claim 17, wherein the at least one connection tab is disposed on an upper surface of the diagonal member.

19. A bridge overhang bracket assembly, comprising:

a top member extending lengthwise between a proximal end and a distal end, the top member comprising upper and lower surfaces;

a diagonal member extending lengthwise between a lower end and an upper end, the top member and the diagonal member being pivotally attached proximate to the respective distal and upper ends thereof;

a side member extending lengthwise between a bottom end and a top end, the diagonal member and the side member being pivotally attached proximate to the respective lower and bottom ends thereof;

a tie bar extending lengthwise between a first end for attachment to a support structure and a second end; and

a connection element mounted to the top member and pivotally attached to the top end of the side member and the second end of the tie bar, the connection element translatable along the top member for adjusting a longitudinal position of the connection element relative to the top member between the proximal and distal ends thereof,

wherein the connection element does not extend above the upper surface of the top member or below the lower surface of the top member.

20. A method of assembling a bridge overhang bracket assembly, the method comprising:

pivotally connecting a top member and a diagonal member proximate to respective distal and top ends thereof;

pivotally connecting the diagonal member and a side member proximate to respective lower and bottom ends thereof;

mounting a connection element to the top member;

pivotally connecting a top end of the side member to the connection element;

translating the connection element along the top member to adjust a longitudinal position of the connection element relative to the top member; and

fixing the longitudinal position of the connection element relative to the top member,

wherein, in step of translating, the connection element does not extend above an upper surface of the top member.
