发明名称 RAIL JOINT ASSEMBLY USING EMBEDDED LOAD TRANSFER KEYS AND METHOD THEREFOR
摘要 A rail joint assembly joining the ends of two rails together includes a pair of joint bars. Each joint bar having one side configured to the rail web side. Mechanical fasteners mount the joint bars to the web sides. Pairs of load bearing keys are embedded in web counter bores at predetermined depths into the webs and embedded in adjacent joint bar counter bores at predetermined depths into the joint bars. The pairs of keys in the webs and the joint bars transfer railway loads through the joint and substantially strengthen the rail joint assembly.
