An elongated hollow rotationally molded high density polyethylene highway barrier has two elongated generally parallel sidewalls, two generally vertical end walls, and a plurality of longitudinal reinforcing members extending from one end wall to the other. The longitudinal reinforcing members extend from respective vertical end walls and terminate in loops which may be joined to like loops on an adjacent barrier for interconnecting the barriers. The longitudinal reinforcing members are typically steel cables. In one form, both end walls have central vertical notches arranged so that the notch end of one barrier may be aligned with the notch end of another barrier and the two barriers moved toward one another with the notches aligned. In this form, there are two steel cables passing through longitudinal holes in each barrier to be joined within the two aligned end notches. In another form, one barrier end is notched vertically while the opposite end has a central vertical protrusion. The protrusion and notch are arranged so that the notch end of one barrier may be aligned with the protrusion end of another barrier and the two barriers moved toward one another with the notch receiving the protrusion to aid in maintaining alignment of the two barriers. In this form, there are four steel cables received in external sidewall grooves. Straps may be provided for retaining the cables in the grooves.
In a New Jersey style barricade system having a plurality of individual hollow molded water-fillable barriers each having interior and exterior surfaces, the barriers being aligned end-to-end in the barricade system, an improved system for joining adjacent barrier ends comprising:
An elongated hollow rotationally molded high density polyethylene highway barrier having a pair of elongated generally parallel sidewalls, a plurality of generally vertical internal reinforcing members extending along each sidewall, a plurality of external longitudinally extending reinforcing members, and a plurality of internal transverse reinforcing members spanning the barrier between a vertical reinforcing member extending along one side wall and a corresponding reinforcing member extending along the opposite sidewall.
An elongated hollow rotationally molded high density polyethylene highway barrier having a pair of elongated generally parallel sidewalls, a pair of generally vertical end walls, a plurality of internal longitudinal reinforcing members comprising a pair of hollow plastic tubes extending through the end walls to provide a pair of hollow cores through the barrier from one end to the other, and the means for joining one barrier to an adjacent barrier comprises a pair of cables, one passing through each tube, and each cable having a bight at each free end for connection with an adjacent barrier, the internal longitudinal reinforcing members extending from one end wall to the other, and means extending from respective vertical end walls for joining one barrier to an adjacent barrier.
An elongated hollow rotationally molded high density polyethylene New Jersey style highway barrier having a pair of elongated generally parallel sidewalls, a pair of generally parallel longitudinally extending cable receiving grooves in each sidewall, a pair of generally vertical end walls, at least two removable longitudinal reinforcing members extending from one vertical end wall to the other and extending from respective vertical end walls for joining one barrier to an adjacent barrier, the longitudinal reinforcing members comprising a plurality of cables, one cable disposed in each groove, each cable having opposite ends terminating in closed loops near respective barrier ends for connection with an adjacent barrier.
