Barrier connection system and connector for use therein

1. A roadway barrier system comprising:

first and second connectors, each connector comprising:

a mounting section attached to an end of a respective roadway barrier unit, the mounting section comprising a web having inner and outer faces;

first and second connector elements at respective sides of the mounting section;

the first connector element comprising an inwardly extending flange that is spaced from the inner face of the mounting section to at least partially define a recess therebetween;

the second connector element comprising an outwardly extending flange joined to the mounting section by a web, wherein the second connector element is devoid of an inwardly extending flange;

the inwardly and outwardly extending flanges of the respective first and second connector elements being dimensioned and orientated such that, when the first and second connectors, each having the same configuration, are each mounted at respective ends of adjacent roadway barrier units and connected together, the outwardly extending flange of the first connector is received within and fully fills the recess of the second connector to form a flush-fitting attachment of the first and second connectors to prevent relative roadway barrier unit translation and rotation, and to form a roadway barrier.

2. The roadway barrier system of claim 1 , wherein the outer face of the mounting section is mounted to an outer surface of an end wall of the respective roadway barrier unit via at least one of screws, bolts, welds, and a connected bracket that is cast into barrier material.

3. A roadway barrier unit, comprising:

first and second connectors, each connector at opposite ends of a roadway barrier unit body, each connector having the same configuration, and each connector comprising:

a mounting section attached to a respective end of the roadway barrier unit body, the mounting section having inner and outer faces;

first and second connector elements at respective sides of the mounting section;

the first connector element comprising an inwardly extending flange that is spaced from the inner face of the mounting section to at least partially define a recess there between;

the second connector element comprising an outwardly extending flange joined to the mounting section, wherein the second connector element is devoid of an inwardly extending flange;

the inwardly and outwardly extending flanges being dimensioned and orientated such that both flanges extend to a distal end in the same direction and that, when the first connector of a first roadway barrier unit and a second connector of an adjacent roadway barrier unit are connected together, the outwardly extending flange of the first connector of the first roadway barrier unit is received within and fully fills the recess of the second connector of the adjacent roadway barrier unit to form a flush-fitting attachment that prevents relative roadway barrier unit translation and rotation, and to form a roadway barrier.

4. The roadway barrier unit of claim 3 , wherein the outwardly extending flange of the second connector element of each connector has generally the same contour and orientation as the inwardly extending flange of the first connector element of each connector.

5. The roadway barrier unit of claim 4 , wherein the inwardly and outwardly extending flanges each have a generally arcuate profile.

6. The roadway barrier unit of claim 3 , wherein respective webs of each connector extend between each of the outwardly and inwardly extending flanges and the mounting section.

7. The roadway barrier unit of claim 3 , with each connector having a unitary construction.

8. A method of assembling a roadway barrier, by connecting together a series of roadway barrier units, comprising the steps of:

(a) providing a plurality of roadway barrier units of claim 4 , with the connectors of each roadway barrier unit in a similar orientation with respect to a respective adjacent roadway barrier unit; and

(b) engaging one connector of the roadway barrier unit with the connector of the adjacent roadway barrier unit by inserting the outwardly extending flange of the connector of the roadway barrier unit into the recess of the connector of the adjacent roadway barrier unit.

9. The method of claim 8 , wherein the connectors of the adjacent roadway barrier units are orientated at substantially 180° with respect to each other in the assembled roadway barrier.

10. The method of claim 8 , wherein step (b) includes vertically aligning the respective connectors of an adjacent pair of roadway barrier units, then lowering one roadway barrier unit into engagement with the other roadway barrier unit.

11. The roadway barrier system of claim 1 , further comprising more than two roadway barrier units connected together in an end-to-end relationship.

12. The roadway barrier system of claim 1 , wherein the first and second connectors have chamfered edges.

13. The roadway barrier unit of claim 3 , wherein the first and second connectors have chamfered edges.

14. The roadway barrier system of claim 1 , wherein at least one of the first and second connectors comprises steel plate or a plastic material such as polycarbonate.

15. The roadway barrier unit of claim 3 , wherein at least one of the first and second connectors comprises steel plate or a plastic material such as polycarbonate.
