An attachment device for provisionally or temporarily connecting a tie plate to a rail includes a U-shaped fixing clamp inserted slightly into a bore of the tie plate. A force-locking connection between the tie plate and the fixing clamp is established with the aid of a clamping bolt. A stop nose automatically also effects a connection between the tie plate and the rail. A simplified tie renewal can be performed as a result of the provisional or temporary connection. A method for producing an attachment device constructed as a fixing clamp is also provided.

A direction-fixation mount secures a track assembly to a flat upper surface of a fixed substrate. The track assembly includes a flat plate having a pair of opposite end edges, a track sitting on the plate, and fasteners securing the track to the plate. The direct-fixation mounting assembly has an elastomeric pad of predetermined stiffness underneath the plate and atop the surface so that the track and plate bears downward via the pad on the surface, and a pair of end restraints each having a rigid outer part fixed to the substrate offset outward from a respective one of the end edges of the plate, a rigid inner part spaced inward from the outer part and fixed to the respective outer end edge of the plate, and an elastomeric mass separate from the pad and fixed to and between the respective inner and outer parts.
摘要:
A sole, ribbed or slide chair plate for a foot of a railroad rail provided with two spaced flat bearing surfaces between which is a concave surface allowing for non tipping of the rail when in place if the bottom of the rail has a convex surface and a shim fitting on top of the plate having a top surface composed of two spaced flat bearing surfaces between which is a concave surface.

A tie cap rail holder for securing a railroad rail to its supporting tie comprises a cap dimensioned to seat gravitationally over the top of the tie in a restricted, longitudinally slidable fit. The cap has on its upper surface a rail seat dimensioned to receive the rail base. On one side of the rail seat an upwardly and inwardly extending detent is dimensioned and positioned for engaging and retaining the adjacent side margin of the rail base. A plurality of the holders are adapted for opposite placement on adjacent ties, with their respective detents engaging opposite side margins of the rail base, thereby securing the rail to the ties.
摘要:
The invention relates to a support for a system for fastening a rail on a substrate, having an angle bracket, which has a base section with a contact surface associated with the respective substrate, also having a supporting section, standing on the base section, which on its free front side associated with the rail to be fastened has a bearing surface, and also having a through hole formed in the base section for inserting a fastening element intended for fixing the angle bracket on the substrate. With such a support reliable support of the rail in service, also with greater tolerance for positioning the individual components, according to the invention is ensured by the fact that the through hole at least in a direction aligned parallel to the contact surface has an over-measure in relation to the circumference of the part, in the assembled condition sitting in the through hole, of the fastening element and by the fact that an additional locking piece, cooperating with the fastening element for fixing the angle bracket in a particular relative position obtained by a relative movement of fastening element and angle bracket, is also provided.
