摘要:
The rail attachment according to the invention is designed for lateral adjustment by up to 15 mm in both directions and it permits vertical adjustment by up to 50 mm without flexural stressing of the screw connection between the attachment and the rigid concrete substructure. According to the invention, the lateral forces are conducted away into the concrete carrier panel (3) via an adjustment profile (2) which is arranged under the webbed panel (9) and conducts away force. An elastic intermediate panel (4) made of elastomer is arranged under the ribbed panel (9) in order to ensure the functionally necessary elasticity.

The invention relates to a solid trackway (1) for rail vehicles having a substantially continuous bedding of the rails (2) on a concrete slab (3), wherein the rail (2) is supported with the foot thereof on an elastic intermediate layer (7). The solid trackway (1) further comprises a side guide piece (8) supporting and guiding the rail (2) in the horizontal direction. The rail (2) is mounted on the concrete slab (3) at discrete mounting points (9) by means of a mounting means (12). Only the elastic intermediate layer (7) is disposed between the rail (2) and the concrete slab (3).

An assembly for mounting a longitudinally extending track on a substrate has a track plate having a top face adapted to carry the track and formed unitarily below the top face with a plurality of longitudinally extending tongues, a base plate at least partially below the track plate, adapted to be anchored to the substrate, horizontally surrounding the tongues of the track plate, and formed with a plurality of longitudinally extending tongues transversely spaced from, longitudinally interleaved with, and horizontally at least partially level with the tongues of the track plate. The track plate and base plate are wholly out of direct engagement with and spaced vertically and/or horizontally from each other. An elastic jacket or liner is engaged between the plates and between the tongues of the track plate and the tongues of the base plate.

Disclosed are different embodiments of a railway tie assembly for securing a rail along a railway track. In one embodiment, the assembly comprises a plurality of composite polymer crossties fabricated from a composition comprising an asphaltic component, a polymeric composition component and a strengthening agent; and a pair of rail clips for securing the rail across each of said composite polymer crossties, wherein each of the rail clips comprises a rail-engagement portion configured to engage a corresponding railseat, and an anchoring portion to be anchored to a given crosstie and cooperate with the rail-engagement portion to secure the corresponding railseat against a load-bearing surface of the given crosstie.
摘要:
The invention relates to a system for fastening a rail (S) to an underlying surface, comprising an underlay plate (4), which has a support surface (20) for the rail (S) to be fastened, and at least one guide plate (5, 6) which is seated on the underlay plate (4) and has a through-opening (38) intended for a clamping element (8, 9) and leading from the free upper side (37) of said guide plate to its lower side (44) resting on the underlay plate (4), which clamping element, with the system completely mounted, is guided through the through-opening (38) and fixedly connected to the underlying surface, wherein a latching connection between the underlay plate (4) and the guide plate (5, 6) is formed in the region of the through-opening (38) of the guide plate (5, 6) by at least one latching arm (25, 26) which engages through the through-opening (38) of the guide plate (5, 6) and has at its free end a latching projection (27, 28) which positively interacts with a stop formed on the guide plate (5, 6). In order to simplify the mounting of the system on the respective underlying surface, a cutout (42, 43) is formed in the circumferential surface (40) delimiting the through-opening (38) of the guide plate (5, 6), in which cutout the respectively assigned latching arm (25, 26) is seated.
