Definitions

  • a rail of a railway track is supported on rail support blocks arranged at intervals under the rail. These blocks are embedded in a concrete slab.
  • the slab is commonly poured around the blocks, but it is also known to place the blocks in corresponding cavities in a slab.
  • a resilient member is present between each block and the slab.
  • EP 919 666 discloses a system wherein a rail support block is placed in a prefabricated tray, e.g. of plastic or concrete.
  • the tray is adapted to be embedded in the concrete slab.
  • elastic elements are arranged, in particular between the tray and the bottom of the block and between each side face of the tray and the opposed face of the block. The fixation of the tray with its elastic elements to the block is based on the clamping forces created by a precompression of the elastic elements by the block as it is placed in the tray.
  • the present invention aims to propose one or more measures that allow to obtain an improved resilient railway support block assembly and/or improved manufacturing method therefor.
  • the prefabricated resilient member comprises an outer tray and inner tray arranged within said outer tray, and said prefabricated resilient member further comprises a resilient intermediate structure being arranged between said outer and inner trays.
  • the present invention further more relates to a method for manufacturing a rail support block assembly, wherein the inventive resilient member is prefabricated, the block is manufactured, and then the block is fixed in the inner tray of the resilient member.
  • An advantage provided by the resilient member according to the invention is that the manufacturing of said member can take place by specialized company in a controlled environment. In this manner perfect quality of the resilient member can be ensured.
  • the process step of creating the adhesion between the inner tray and the block is found to be less complicated and sensitive than the adhesion discussed above between the pourable resilient material and the concrete components as discussed with reference to applicants prior art assembly. Therefore said adhesion can take place at the location of the production of the concrete block or even at another location (e.g. at the railway installation site).
  • the prefabricated resilient member 1 has an outer tray 2 and an inner tray 3 arranged within said outer tray 2.
  • the inner tray 3 has dimensions here so that it can be held spaced from the outer tray 2 in all directions.
  • said distance between the main faces of the inner and outer trays 2,3 generally is preferably at least 5 millimetres and preferably at most 20, more preferably at most 15 millimetres.
  • a resilient intermediate structure 5 is arranged between said outer and inner trays 2,3. Said structure 5 here also interconnects said trays 2,3 so as to form a unitary assembly with said trays, preferably as said structure 5 is bonded to the faces of each of the trays 2,3.
  • the resilient structure 5 has been obtained by arranged the trays 2,3 spaced from each other and then pouring (or similar) a suitable elastomeric material between the outer and the inner tray 2,3. As the material has been poured (or similar) between the trays 2,3 the material bonds to essentially the entirety of the main faces of the inner and outer trays 2,3, preferably so that no interface exists which would allow for the ingress of water or the like.
  • the outer and inner trays 2,3 are spaced from one another so as to have no points of contact and the intermediate resilient layer 5 allows for elastic motion of the inner tray (which will receive the block) in all directions.
  • the elastomeric material of structure 5 and the trays 2,3 are preferably designed and selected such that a strong adherence or bond is obtained between the inner faces of the trays and the elastomeric material.
  • the elastomeric material can a polyurethane elastomer, such as e.g. Corkelast made by the applicant.
  • FIG. 1 shows a sandwich type prefabricated resilient member, wherein a layer of the elastomeric material 5 is sandwiched between the trays 2,3.
  • the resilient intermediate structure 5, here layer of elastomeric material 5, is adapted to maintain its resiliency during its service life.
  • said structure 5 (and the resilient assembly in which it is integrated) should be able to serve in railways lines as specified in UIC code 700, "Classification of lines and resulting load limits for wagons", a relevant code of the International Union of Railways.
  • the inner faces of the trays 2,3 are preferably made with an adhesion enhancing surface, e.g. rough as in the drawings, and/or provided with adhesion enhancing formations, such as ribs, lugs, etc.
  • the inner faces of the trays 2,3 can be subjected to an adhesion enhancing pre-treatment, e.g. a mechanical treatment or a chemical treatment.
  • an adhesion enhancing pre-treatment e.g. a mechanical treatment or a chemical treatment.
  • the trays 2,3 can be made from the same or from different materials.
  • the inner tray could be made from plastic and the outer tray of metal.
  • a metallic outer tray would result in a high resistance against damage and/or penetration of the outer tray possibly affecting the functioning of the resilient material.
  • a metallic outer tray e.g. of steel, could also be chosen as it could allow for mounting or integrating the tray into a steel structure, e.g. on a steel plate or on a steel member of a railway bridge or the like.
  • the steel outer tray could be provided e.g. with a flange which can be fastened to said further steel structure.
  • the wall thickness of the trays 2,3 could be the same or differ e.g. depending on the selected material and/or application
  • one or more preformed elastic elements e.g. an elastic mat or plate (e.g. of a suitable foam), are placed between the trays 2,3 and possibly adhered to both trays using a suitable adhesive.
  • an elastic mat or plate e.g. of a suitable foam
  • any remaining spaces between the trays 2,3 are filled with a pourable elastomeric material, as explained with regard to structure 5 in figure 1.
  • Figure 1 further shows an example of a railway support block 10.
  • This block 10 here is made a pourable material which is poured in a suitable mould at a production location.
  • the block 10 is made of concrete. It is envisaged that said concrete can be a polymer concrete. Other concrete containing embodiments of the block, e.g. including reinforcement materials, are also envisaged.
  • the block could also be made of other materials, such as from steel, e.g. a cast block or a welded steel block.
  • the block 10 has a top 11, a bottom 12 and peripheral wall 13.
  • the block 10 is adapted as a monobloc for supporting a single rail of a railway track, but the block could also be designed as a duo-block supporting two or even more rails (as a railway sleeper).
  • the block 10 here has a significant height.
  • one or more rail fastener members 15 are provided on the block 10. Also an elastic plate 16 is positioned here on top of the block 10, which will lie under the rail.
  • FIG 2 it is also shown that the block 10 has been fixed in the inner tray 3 here, as is preferred, by application of a suitable adhesive 17 between the inner tray 3 and the block 10.
  • This adhesive preferably hardens so as to be rigid in hardened condition, thereby rendering the inner tray 3 a unitary body with the block 10.
  • Such adhesives are known I the field and are e.g. sold under the trade name DEX.
  • the inner dimensions of the inner tray 3 are preferably selected so as to take account of any variations of the dimensions of the block 10 as a result of the block production method.
  • figure 3 it is shown that the assembly of figure 2 is mounted on a rail 20 to be installed.
  • said rail 20 is held in its desired position by temporary supports.
  • a concrete or asphalt slab 25 has been poured below the rail 20 so as to embed the resilient member 1 in the slab 25.
  • the outer tray 2 can have a roughened exterior and/or anchoring formations (e.g. ribs(s), lug(s), bolts or pins, etc. protruding outwards from the tray 2).
  • outer tray 2 with inward sloping peripheral wall or parts thereof, so that the embedded outer tray can not be pulled upwards out of the slab.
  • a tray could be provided with one or more perforations.
  • the assembly is not embedded but fastened onto a substructure, e.g. on a substructure plate (metal or concrete) or a beam.
