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.

The present invention is directed at an improved device for joining together abutting railway rails between two railway ties. The rails to be joined together have a head portion, a web portion and a toe portion. The saddle is split at the bottom and joined with the two bottom (lower) bolts. The saddle hugs the base of the rail at the joint preventing differential vertical (shearing) displacement of the two rail ends. This can be used in insulated and non-insulated joints. The bolts are isolated from the bars and saddle and directly contact the rail.

A rail joint assembly is provided for joining abutting railroad rails with an electrically-insulated joint. The rail joint assembly comprises abutting railroad rails compressing an insulating gasket therebetween and rail joint bars secured through a plurality of holes by fasteners to the adjacent railroad rails. The rail joint bars comprise a body and an insulating spacer comprising a porous mesh screen and washer. A layer of epoxy is sandwiched between a rail joint bar and railroad rail and comprises a rigid epoxy on lateral portions of a first side of a rail joint bar and a flexible epoxy placed on a central portion of the first side of a rail joint bar. Rail joint bars are rectangular shaped and may have a cutout.

The temporary rail bridge (20) of the illustrated embodiment includes a bridge number (20) that is coupled to a track rail (16) by screw clamps (24). Each of the screw clamps (24) includes an internal tensioning component such as a spring (58) that allows for fast installation of the rail bridge (20) and maintains continuous pressure engagement in operation. The rail bridge (20) reduces track closure time due to rail damage and associated costs and inconvenience.

A track element for a linear motor vehicle, providing both for guiding and traction of the vehicle, and a track using such an element. The track comprises rails having a cavitied limb and a sole piece. The walls of the limb are at an angle of from 2* to 5* to each other. Provided at the top of the limb is a tubular bead-shaped portion. A means for fish-plating the rails comprises at least one sealing joint and a fish plate straddling two rails and slid into two corresponding cavities.

A rail connection for overhead or suspended conveyors or the like in which the rail ends are connected with one another by connection means. According to the invention, the connection means comprises at least one centering bolt member arranged at the rails of a rail joint, this centering bolt member being displaceable in the direction of the rails and serving to interconnect both rail ends.
摘要:
Two rail ends are temporarily interconnected by two clamping members extending along the webs of the rail ends by bridging the rail ends to hold the webs clamped therebetween. The two clamping members are centrally anchored on a spacing member positioned between the rail ends.
