A conducting rail retention system includes a plurality of conducting rails and a rail support assembly. The rail support assembly includes a support pole, the support pole including a top end and a bottom end, a support plate, the support plate being attached to the top end of the support pole, the support plate including a rail support portion on a top surface of the support plate, and a pair of rail clamps movable relative to one another from a rail unlock position to a rail interlock position securing the plurality of conducting rails to the support assembly.

A bearing apparatus has a mounting element for mounting a construction element of a steel construction, a base element to be fastened to a supporting structure and an adjustable compensation device for adjusting a height position and an angular position of the mounting element relative to the base element and supporting the mounting element at the base element in direction of a virtual main axis. The compensation device comprises a mechanical series connection of a lockable articulated joint arrangement and a supporting column. The unlocked articulated joint arrangement allows the mounting element to be pivoted relative to the base element about any pivot axis orthogonally intersecting the main axis. The supporting column has a length which is variable by screwing an inner column in an outer column of the supporting column. A screwed-in position of the supporting column is fixed by the construction element mounted to the mounting element.

A direct fixation fastener in a track fixation system includes a track plate forming cutouts in opposite ends thereof, a first end restraint positioned in a first of the cutouts and a second end restraint positioned in a second of the cutouts. Each of the end restraints includes at least one fastener hole therein, such as an elongated fastener hole for lateral adjustment, and an uplift-limiting protrusion including a hook portion extending over the track plate. The fastener further includes a jacket including a non-metallic jacket material attaching the track plate to each of the first end restraint and the second end restraint and extending therebetween.
