Definitions

  • the invention relates to a system for fastening a rail.
  • the system includes in general terms the components needed to secure the rail, while the mounting of the rail refers to the concrete mounting of the rail as given in practical conditions.
  • Fastening systems and fasteners of this type are for example in WO 03/04 6284 A1 , the German patent application DE 33 24 225 A1 or the German utility model DE 201 22 524 U1 described. They serve in particular for supporting a rail on a so-called solid ground. Such solid substrates are also referred to as "fixed carriageway" and, in contrast to a track superstructure formed from loose gravel, have no inherent resilience.
  • the solid substrate itself can be formed, for example, by concrete slabs on which the rails are mounted directly, or by sleepers, which are also made of solid material, such as concrete.
  • the fastening system comprises sleepers that form the substrate on which the rails are to be attached
  • these thresholds usually lateral stop shoulders. These limit on the one hand laterally between a recess in which sit the rail and the components required for their attachment.
  • the shoulders serve as stops against which the guide plates intended for laterally guiding the respective rail are supported.
  • these guide plates are either fixed directly to the solid ground or the respective threshold or fixed via intermediate components, such as force distribution plates on the ground.
  • the fastening elements additionally serve for tensioning spring elements which exert a holding force directed towards the solid base on the rail foot.
  • additional shims and fasteners are needed to properly align and hold the rails.
  • the known fastening systems ensure a secure hold of the rails of a track body even under the highest loads, such as occur in high-speed operation. Due to the large number of elements required for each individual attachment point, however, the cost of producing and mounting such a fastening system is considerable.
  • the invention was based on the object to provide a system for fastening a rail that can be mounted in a simple manner so that a sufficient positional securing of the support element is ensured.
  • This object is with respect to a system for mounting a rail on a substrate, which provided for laterally guiding the rail guide plate having a ground surface associated with the base, a support member which is provided, the guide plate in the assembled position on its from the Support rail side facing against a stop and to a guide plate associated contact surface and the stop associated support surface has a spring element which is intended to be supported on the guide plate and at least one spring arm for exerting an elastic holding force on the foot of the rail ,
  • a tensioning means for tensioning the spring element comprises, according to the invention solved in that the support member has a support shoulder, which is intended to be supported in the mounting position on the ground and thereby to grip under the standing surface of the guide plate, there ss the guide plate over the support shoulder in the area where the guide plate and the support shoulder overlap is supported on the ground.
  • the above-mentioned object with respect to a fastening of a rail on a substrate which guides a guide plate, which stands with its footprint on the ground and the rail side, a support element, which with a contact surface on a corresponding contact surface of the guide plate abuts and is supported by a support surface on a stop, a supported on the guide plate spring element which exerts at least one spring arm an elastic holding force on the foot of the rail, and a clamping means by which the spring element is clamped against the guide plate, according to the invention thereby has been solved that the support member has a support shoulder which is supported on the ground and thereby engages under the standing surface of the guide plate, that the guide plate in the region in which overlap the support shoulder and the guide plate, on the support shoulder on the Unt reason is supported.
  • the central idea of the invention is that in a fastening system according to the invention and a fastening according to the invention the guide plate is on the support element.
  • the support member is loaded in this way over a large area by the force acting in the direction of gravity force, by which the guide plate is held in position. In this way, any unintentional lifting of the Support element even then reliably prevented if the support element has not been optimally mounted or material wear has occurred over time, as a result, the prevailing friction between the support element and the guide plate decreases.
  • the assembly of a system according to the invention to a fastening according to the invention is particularly simple. This is achieved in that the paragraph present on the support element according to the invention is designed so that it engages in the mounting position below the guide plate. Accordingly, after a corresponding positioning of the support element, the guide plate only has to be placed on the relevant section of the support element. This can be done in a very simple movement, which requires neither special knowledge nor special tools.
  • the support member and the guide plate are not only positively connected to each other, but this positive connection is superimposed with a frictional, caused by the force exerted by the guide plate on the support portion of the support member clamping forces connection, which is an automatic release of support member and guide plate safely prevented from its proper mounting position.
  • the invention is suitable for such fastening systems and fasteners in which the rail is mounted on a serving as a base threshold on which a shoulder is formed, which forms the stop on which the support member is supported.
  • a corresponding stop on a plate extending over a large area or to form it by means of an additional angle element mounted on a threshold or a plate.
  • a groove may be formed in a conventional manner, which extends in the longitudinal direction of the rail to be fastened at the transition to the stop.
  • a shoulder of the guide plate engages in this groove a shoulder of the guide plate to secure the position of the guide plates in a direction transverse to the rail direction by a positive fit. If such a groove is formed in the threshold, so in a system according to the invention, the support shoulder of the support member is formed so that it sits in the groove when fully assembled. The groove can thus be used in addition to securing the position of the support element.
  • a material-saving and easier-to-install embodiment of the invention is, however, characterized in that the guide plate in the region of its side portion assigned to the support element has a recess into which the support shoulder of the support element engages. This recess preferably extends over the entire length of the support element measured in the longitudinal direction of the rail. In this way, the support member and the guide plate can be during assembly mounted in the ground state in the longitudinal direction of the rail relative to each other until their proper position is reached.
  • the support section acts like a guide rail.
  • This function can additionally be assisted by the fact that the recesses have at least two step-wise offset sections whose depth measured transversely to the longitudinal extent of the rail is different and the support section of the support element is shaped such that it rests positively against the surfaces of the shoulders of the recess.
  • An optimal support of the guide plate results in this case when the deepest portion of the recess is associated with the ground.
  • a multi-stage design of the recess and the friction surface between the support member and the guide plate is increased, whereby after tightening the guide plate on the ground a further improved security in the position assurance of the support element is achieved.
  • the position assurance of the support element can be additionally supported by the fact that on the support element and the guide plate mutually corresponding form elements are designed for the positive connection of the support element and the mold element.
  • the mold elements may be designed as projecting ribs and recessed, correspondingly shaped recesses. These may for example be formed on the contact surface of the support element as a strip-like projections and / or recesses, which are positively doubled with at least one correspondingly shaped forward and / or return, which is formed on the respective contact surface of the support element associated bearing surface of the guide plate.
  • more than one such shaped element is preferably formed on the contact surface associated with the guide plate.
  • the conditions are created that in a fastening according to the invention, the guide plate and the support element are particularly securely connected to each other and large friction surfaces are available on the existing by the installation self-locking unintentional displacement of the support element in the finished mounted state is prevented.
  • a further increased security against unwanted displacement can be achieved in that the form elements extend substantially perpendicular to the base of the guide plate. By aligned and interlocking mold elements, any displacement of the support member in the longitudinal direction of the guide plate is prevented in the mounting position.
  • the effectiveness of the loading of the supporting element with the holding force transmitted by the guide plate can be further improved by forming a loading section on the guide plate, which rests in the assembly position on the free upper side of the supporting element.
  • a loading section on the guide plate, which rests in the assembly position on the free upper side of the supporting element.
  • elements for positive connection on the free upper side of the support member may be formed in the area in the mounting position of the loading section the guide plate is covered.

  • a projection may be formed on the side of the guide plate associated with the rail to be fastened, which under the mounting base engages under the base plate or the rail foot.
  • This projection prevents particularly safe and yet easy way lifting the guide plate under unfavorable operating conditions.
