Abstract
A crash barrier that includes barrier sections that are overlappingly joined in assembly. Each section includes a concave center segment cojoined to upper and lower convex sections. Elongated longitudinally extended studs are punched out of one end of each section within the concave center segment. The studs are arranged to engage receiving slots in the other end of each section to facilitate assembly and alignment of the sections upon vertically disposed posts that are driven into the ground. A special machine for assembling and aligning the sections with the support posts is also disclosed.
Claims8
A crash barrier that includes:
- longitudinal barrier sections that are arranged so that one end section of a first barrier section overlaps the other end of a second adjacent barrier section to establish overlapping regions between adjacent barrier sections,
- a first interlocking means for connecting one end section of a first barrier section to an opposite end section of a second adjacent barrier section, said interlocking means further including an elongated longitudinally disposed stud that is integrally formed in the overlapping region of said first barrier section and is slidably received within a slot formed in the overlapping region of said second adjacent barrier section to lock adjacent sections together in assembly,
- fastening means in each overlapping region to further secure the adjacent barrier sections together in assembly, and
- vertically disposed support elements connected to the barrier in each overlapping region.
A method of erecting a crash barrier that includes the steps of
- integrally forming an elongated longitudinally disposed stud in one end of each barrier section and a slotted hole in the opposite end of each barrier section,
- placing a first barrier section flat upon the ground and a second barrier section on top of the first barrier section so that one end of a first section overlaps the opposite end of the next adjacent section,
- inserting the stud of each first section into the slot of each second section and exerting a force on the adjacent sections to interlock the adjacent sections together to form a connected run of sections,
- raising the sections of a run into a vertical plane and positioning the overlapping regions of adjacent sections on spaced apart vertical supports,
- driving the supports into the ground and checking the depth of each support,
- detecting automatically when a mounting hole formed in each overlapping region is aligned with a receiving hole in a vertical support, and
- securing each overlapping region to a support by mounting a fastener in each aligned hole.
