Abstract

A system for paving a bridge comprising a screed rail configured to support a concrete paver and a plurality of adjustable width barrier brackets to support the screed rail with a bridge barrier, where each adjustable width barrier brackets comprise a rail support bracket and an “L” barrier bracket which allows for width adjustment by translation of the rail support bracket through the “L” barrier bracket.

First claim

We claim:

1. A system for supporting a concrete paver, of the type having a motorized truss and a motorized reciprocating carriage, the system comprising:
a plurality of adjustable barrier brackets, each of which is configured to be placed over a pre-existing barrier and is able to be reconfigured to reduce any free space between any contact portion of any adjustable barrier bracket and a barrier, without any material being wedged between said contact portion and any barrier;
wherein each of said plurality of adjustable barrier brackets is able to be reconfigured without the use of any tools; and wherein each of said plurality of adjustable barrier brackets comprises a rail support bracket and an “L” barrier bracket; and
wherein said “L” barrier bracket further comprises a first L plate and a second L plate, and a connection plate; which are configured in combination to permit the rail support bracket to translate through the “L” barrier bracket.

2. The system of claim 1 wherein said rail support bracket is configured with surface features capable of cooperating with other members to temporarily fix a width dimension for said adjustable barrier bracket.

3. A system for supporting a concrete paver by a portion of a bridge comprising:
a plurality of barrier brackets each being configured to be placed over a barrier and having:
a first side support bracket;
a second side clamping bracket;
a rail support system coupled to a lower portion of said first side support bracket;
structure configured to cooperate with both said first side support bracket and said second side clamping bracket to permit regulation of a width characteristic of a barrier bracket by controlled relative movement therebetween; and
a rail disposed between and supported by said plurality of barrier bracket.

4. The system of claim 3 wherein said first side is a paving side and said second side is a non-paving side and wherein said structure is one of a portion of said paving side support bracket, said non-paving side, clamping bracket, or an additional member which engages both said paving side support bracket and said non-paving side clamping bracket.

5. The system of claim 4 wherein said structure comprises a pin and wherein said rail is a screed rail.

6. The system of claim 5 wherein said pin engages a protuberance or a hole in each of said paving side support bracket and said non-paving side clamping bracket.

7. The system of claim 6 wherein said pin engages a hole through each of said paving side support bracket and said non-paving side clamping bracket.

8. The system of claim 7 wherein said non-paving side clamping bracket further comprises a first L plate and a second L plate.

9. The system of claim 8 wherein said pin engages both of said first L plate and said second L plate.

10. The system of claim 9 further comprising plurality of contact pads disposed at positions where contact between the adjustable barrier bracket is configured to engage with a bridge barrier.

11. A system, configured to be placed over a barrier, for supporting a concrete paver by said barrier having a predetermined barrier width characteristic, comprising:
a) means for supporting a rail, with a width adjustment hole array;
b) means for providing an “L” barrier connection, with a pair of coaxial holes;
c) means for changing an alignment of said pair of coaxial holes in said “L” barrier connection from being aligned with said first array hole in said width adjustment hole array, by translating the “L” barrier connection along the means for supporting a rail support so as to be in alignment with a second array hole in said width adjustment hole array; and
e) means for creating an adjusted barrier bracket by pushing a first pin through a second one of said pair of coaxial holes in said “L” barrier connection, pushing the pin through said second array hole and then through said first one of said pair of coaxial holes in said “L” barrier connection.

12. The system of claim 11 wherein said means for supporting a rail has a barrier bracket tube disposed thereon.

13. The system of claim 12 wherein said barrier bracket tube has a height adjustable rail support system disposed therein and wherein the concrete implement is a paver.

14. The system of claim 11 wherein the system is free of any material wedged between any portion of any of a plurality of adjusted brackets and a barrier.

15. A system for supporting a concrete paver, of the type having a motorized truss and a motorized reciprocating carriage, the system comprising:
an adjustable barrier bracket, which is configured to be placed over a pre-existing barrier and is able to be reconfigured to reduce any free space between any contact portion of any adjustable barrier bracket and a barrier, without any material being wedged between said contact portion and any barrier; and
wherein said adjustable barrier bracket is able to be reconfigured without rotating a first threaded member with respect to a second threaded member.

16. The system of claim 15 wherein said adjustable barrier bracket comprises a rail support bracket and an “L” barrier bracket.
