ROUNDWOOD HIGHWAY GUARDRAILS |
摘要 |
Road safety guardrails are constituted by vertical wooden posts carrying at least one horizontal rail made up of wooden logs which are connected end-to-end by pairs of metal straps which are interconnected by bolts, each passing through both straps and one or other of the logs. Each inter-log connection is reinforced by incorporating metal rods that run through each log and intersect the diametrical plane containing the bolts for interconnecting the straps. |
