ABSTRACT:
A sectional shock-absorbing and motorist warning highway barrier is provided in the form of multi-component sections about four feet in length, and adapted to be joined together in end-to-end relation to form a continuous barrier, each section being made up of four vertically aligned horizontal components, providing a top component, and two mid-components of uniform thickness, and a flared bottom component, such components having offsets at opposed ends thereof for aligning successive sections with such offsets having transverse apertures for receiving bolts in securing together successive sections, abutting surfaces of the horizontal components having aligned offsets of semi-spherical contour to receive spherical plastic bumper members protrudingly and rotatably supported in the assembled section. The horizontal components are fashioned from concrete, suitably encased in plastic shells, and the spherical plastic bumper members may be either air filled, or filled with water or sand for added weight. The offsets for aligning successive sections are for direct section-to-section engagement, or for reception of vertically oriented, and suitably flexible interfitting connecting members. With either type of section-to-section connections the free ends of a multi-sectional assemblage are provided with appropriately contoured vertical connecting members interfitting with the aligning offsets, preferably including means providing visibility enhancement.
