Definitions

  • the invention relates to a frame for a track covering for a slab track according to the preamble of claim 1.
  • a track covering of a slab track is known, which is produced by pouring a sheet metal frame with in-situ concrete.
  • the sheet metal frame serves as permanent formwork.
  • Such a frame is placed on each long side of a rail. It has been shown that the distance between adjacent frames, measured perpendicular to the longitudinal direction of the rails, is too large for non-rail vehicles with narrow rubber tires. However, the adjacent frames cannot be arranged as close to one another as would be necessary to ensure safe trafficability with a rail-bound vehicle. The reason for this is, among other things, that the attachment of the rails to the rail supports of the slab track would be covered. For safety reasons, however, it must be possible to check these attachments at any time.
  • a slab track is known in which a free area between the cover element designed as a precast concrete part and the rail is covered by a one-piece metal sheet that is attached to the precast concrete part and protrudes into the free area in the direction of the rail.
  • the invention is based on the object of further developing a generic frame in such a way that the track covering of a slab track is possible in such a way that it can be safely driven on with a rail-bound vehicle and at the same time a fastening device for fastening the rail can be checked in the operating position of the frame is.
  • the longitudinal sheet metal is shaped in such a way that it has an inspection section for forming an inspection space for inspecting a fastening device for fastening the rail when the track covering is in the operating position. Furthermore, the longitudinal sheet metal is shaped in such a way that, when the frame is in use, it has a travel section for forming a concrete surface that can be driven over by the rail-bound vehicle. When in use, a first, greatest distance between a rail plane of the rail and the inspection section is greater than a second, smallest distance between the rail plane and the travel section. When the frame is in use, the rail plane is oriented perpendicular to the concrete surface to be formed. The rail plane borders on the rail head of the rail on the side of the rail head facing the frame.
  • the longitudinal plate can be shaped in such a way that the frame can be placed close enough to the rail to ensure that the track covering can be safely driven over by a rail-bound vehicle, and at the same time the longitudinal plate can be shaped in such a way that the fastening device can be inspected in this position of use is possible.
  • the fastening device can be inspected by looking in the same direction the fastening device can be viewed from above on the rail.
  • the longitudinal plate can be shaped in such a way that in the position of use between the rail and the inspection section the inspection space for inspecting the fastening device is formed.
  • the frame advantageously has a total of two longitudinal plates and two end plates. However, it can also be provided that the frame has only one longitudinal metal sheet and is otherwise formed by wooden boarding.
  • the frame is a sheet steel frame, in particular made of galvanized sheet steel.
  • the frame expediently has an opening at the bottom.
  • in-situ concrete poured into the frame can adapt to the floor surface of the slab track and absorb forces very well when hardened.
  • the opening of the frame is lined with a separating film before the in-situ concrete is introduced.
  • the base of the slab track is therefore not touched by the in-situ concrete. This ensures that the in-situ concrete can adapt to the subsoil when poured, but the frame can still be removed without any problems because the in-situ concrete is not firmly connected to the subsoil.
  • the frame is intended to rest on a rail support of the slab track in the operational position, that a lower tangential plane running perpendicular to the rail plane touches the rail support from above, and that the inspection section in the operational position is attached to the lower tangent plane adjacent. This ensures that the inspection section can be placed in the position of use at the point where the inspection space is required for inspecting the fastening device.
  • the frame When in use, the frame has a vertical direction that runs perpendicular to the lower tangential plane.
  • the frame has a high area.
  • the high area extends in the vertical direction from the lower tangent plane to an edge of the frame.
  • the driving section is expediently arranged at least in the upper half of the high area. This ensures that the driving section of the longitudinal plate, which is used to form the concrete surface that can be driven over by the rail-bound vehicle, is arranged in the area in which the concrete surface is to be formed.
  • the inspection section advantageously extends in the longitudinal direction at least over a section of the longitudinal side of the rail of the frame. Provision can also be made for the inspection section to extend over the entire longitudinal side of the rail of the frame.
  • the inspection section and the driving section are next to each other in the vertical direction in the operational position.
  • the driving section is expediently arranged above the inspection section.
  • the driving section is arranged exclusively in the upper half of the high area in the operational position.
  • the longitudinal sheet metal arranged on the rail longitudinal side of the frame runs obliquely to the rail plane of the rail, at least in the high region above the lower tangential plane.
  • the longitudinal plate is expediently oriented in the high area at an angle of 10° to 30° to the rail plane.
  • the inspection section and the driving section are next to one another in the longitudinal direction when in use.
  • the inspection section is advantageously designed in such a way that, in the operational position, it extends in the longitudinal direction over at least 70% of the entire extension of a rail bearing in the longitudinal direction. A sufficiently large inspection space can thereby be formed. This allows the fastening device, by means of which the rails are fastened to the rail support, to be inspected.
  • the driving section extends over the entire vertical area of the longitudinal plate in the operational position with respect to the vertical direction.
  • the high area is above the lower tangent plane.
  • the travel section When in use, expediently runs parallel to the plane of the rails.
  • the inspection section When in use, expediently runs parallel to the plane of the rails. As a result, simple production of the longitudinal sheet metal is possible.
  • a width of the frame measured perpendicular to the rail plane can be adjusted by means of an adjustment device. This allows, for example, the distance between the frame and a tunnel edge path to be adjusted. This allows very narrow gaps to be created between the frame and an edge path. Any tolerances in the edge of the border path can be compensated for by adjusting the width of the frame. In this way, a constant joint width can be achieved.
  • the longitudinal plate has an opening for a support element for supporting the longitudinal plate on a floor of the solid track.
  • the longitudinal plate can be supported in a simple manner.
  • the concrete surface and the in-situ concrete below the concrete surface are subjected to severe bending loads.
  • the bending tensile stresses are supported by the longitudinal sheet metal carried away by the support element.
  • the in-situ concrete can be poured without inserting reinforcement.
  • the longitudinal plate has a protruding section which, when the frame is in the operating position, borders on the lower tangential plane, and that the protruding section runs transversely to the rail plane in the operating position.
  • the protruding section can be provided to protrude over a rail bearing in the direction of a rail when in use. As a result, a gap between the rail and the frame can be made very small. This increases safety when driving on the track cover with a non-rail vehicle.
  • the driving section expediently protrudes in relation to the projection section and in relation to the inspection section in the direction of the plane of the rails in the operating position.
  • the opening for the support element for supporting the longitudinal plate on the floor of the solid track is advantageously arranged in the projection section of the longitudinal plate.
  • a support element is expediently introduced into the opening, which extends in the vertical direction in the position of use.
  • the support element is arranged in the opening so that it can be displaced in the vertical direction when it is in use.
  • the floor of the slab track is usually not completely level. Its height can vary by +/- 20 mm. Such variations can be compensated for by the displaceable arrangement of the support element in the opening.
  • the support element can be displaced in the opening in such a way that the support element stands on the floor of the slab track.
  • the supporting element is designed to be hollow for filling with in-situ concrete. This allows the in-situ concrete when pouring into the hollow Adapt the support element to unevenness on the slab track floor. In this way, forces can be optimally transferred from the hardened in-situ concrete via the ground to the slab track.
  • the support element is expediently a sheet metal tube with any desired cross-sectional contour.
  • the support element is a post made of solid material.
  • the opening is advantageously arranged in the area of a travel section.
  • the support is provided by the support element directly in the area in which forces may be transmitted from a rail-bound vehicle via the concrete surface formed by the driving section to the hardened in-situ concrete and the driving section of the longitudinal plate.
  • the longitudinal plate can be supported in areas between the rail supports.
  • support can be provided in the areas in which the protruding section would otherwise have no downward support.
  • the opening is expediently arranged below the concrete surface to be formed by the driving section, which can be driven over by the rail-bound vehicle.
