Definitions

  • the invention relates to a sleep block unit for railroad track systems, comprising a sleep block and a threshold shoe partially surrounding this sleep block, the sleep block having a head area and a foot area with side panels and a bottom surface, and wherein the head area is longer and wider than the foot area such that between There is a paragraph in the header area and the foot area.
  • Threshold block units are used in so-called slab tracks, which are increasingly preferred to the so-called ballast lanes, because it increases the performance of the road in terms of achievable speeds and reduces maintenance costs.
  • Such sleeper block assemblies include a generally concrete block, a generally molded rubber shoe that receives the block, and a resilient elastomeric damper disposed between the bottom of the block and the bottom of the shoe.
  • a mounting system for a rail is arranged on top of the block. The shoe is poured with concrete.
  • the documents EP1017906B1 and DE4335516A1 both show a threshold block with a threshold shoe partially surrounding it, wherein at the upper edge of the threshold shoe an elastic sealing lip abutting the substantially vertically oriented outer wall of the threshold block is arranged.
  • These arrangements have the disadvantage that during the vertical movements of the sleeper block, the sealing lip rubs against the outer wall of the sleeper block and is thus subject to wear, as a result of which the sealing effect decreases over time.
  • an arrangement is described with a threshold block and a threshold shoe, the latter having at the upper edge a circumferential sealing arrangement which sealingly engages in a specially provided, circumferential groove in the sleeper block. This groove complicates the manufacture of the threshold block.
  • the patent application describes FR2840330A1 an arrangement with a threshold block and a threshold shoe, the latter having at the upper edge a relatively complicated sealing arrangement, the lower With the help of a flowable sealing material is created.
  • the invention is based on the object to provide a threshold block unit of the type mentioned, in which the seal assembly is simple and yet subjected to low wear during operation.
  • a circumferential sealing lip is arranged, which is directed upwards and outwards and abuts the shoulder.
  • This solution according to the invention has the particular advantage that the vertical direction of the threshold block in the sleeper shoe deforms the sealing lip essentially vertically in the elastic region and does not rub against an outer wall of the sleeper block as in the case of known threshold block units. As a result, the sealing lip is less worn, whereby the sealing effect is maintained longer and the threshold block unit has a longer life.
  • the shoulder forms a contact surface, which is partially oriented at least approximately parallel to the bottom surface. This contact surface presses the compression lip of the emerging block in the sleeper shoe vertically together.
  • a transition region between sidewalls of the foot region and the heel is rounded. In this rounding fits the advantageous Sealing lip, so that there is a relatively large contact surface between the sealing lip and the threshold block.
  • a circumferential, outwardly directed nose is arranged on the threshold shoe in the foot region of the sealing lip.
  • this nose serves as an indicator of the level of the concrete with which the threshold block unit is to be cast in, on the other hand the nose forms a stable base for the sealing lip.
  • both the foot region of the sleeper block and the sleeper shoe decrease in length and width from top to bottom.
  • the Figures 1 and 2 each show a partially cutaway side view of an embodiment of an inventive threshold block unit 1, with a view once on the long and once on the short side of the threshold block unit 1, which has a substantially rectangular plan.
  • the threshold block unit 1 corresponds to those described in the document except for the sealing lip 14 described below DE10196374B4 is described and consists of a threshold block 2 made of concrete and a surrounding this on a portion of its height threshold shoe 3 made of elastomeric material, preferably made of rubber.
  • the threshold block 2 has a head portion 4 with a bearing surface 5 for rail fastening means (not shown).
  • the threshold block 2 has a foot region 6 which is shorter and narrower than the head region 4, so that a heel 10 exists between the head region 4 and the foot region 6.
  • the side wall surfaces 7 of the foot portion 6 are slightly inclined, so that the length and width of the foot portion 6 decrease downward. Thus, the replacement of the threshold block unit 1 is made possible without the surrounding concrete has to be broken.
  • the bottom surface of the threshold block 2 is designated. Said paragraph 10 forms a circumferential, in the outer region at least approximately parallel to the bottom surface 8 oriented contact surface, whose function will be described below.
  • the transition region 9 between the side wall surfaces 7 and the shoulder 10 is preferably rounded as shown.
  • the threshold shoe 3 has four side walls 11 and a bottom 12 and between the bottom surface 8 of the threshold block 2 and the bottom 12 of the threshold shoe 3, an elastic insert 15 is arranged, which allows a vertical movement of the threshold block 2 in the threshold shoe 3 during operation under load.
  • On the outer walls 11 of the threshold shoe 3 is a horizontally extending nose thirteenth arranged in the concreting of the threshold block unit 1 as an orientation for the level of concrete to be maintained, which in the Figures 1 and 2 indicated by line 16.
  • a circumferential sealing lip 14 is arranged, whose free end is directed outwards and rests from below on the contact surface formed by the shoulder 10.
  • the sealing lip 14 is resiliently bent by the contact surface, always keeping in contact with the contact surface and thereby reliably seals the gap between the threshold shoe 3 and the threshold block 2.
  • the resilient bending results in relatively little friction between the sealing lip 14 and the sleeper block 2, so that the inventive threshold block unit 1 despite a simpler structure has a longer life than known threshold block units.
