Definitions

  • the invention relates to a connecting lug for a rail butt joint, the lug being screwed to the rails, in particular screwed high-strength, and possibly glued, the lug body essentially filling the cavity between the rail head, rail web and rail foot made of high-strength, in particular fiber-reinforced plastic, as a one-piece molded body is and has at least four passage openings for connecting screws, and wherein the tab body is reinforced on its outer side in the installed state by a rib extending from one to the other end face of the tab body, which extends over a substantial part of the tab body height.
  • a connecting lug of the type specified in the introduction which is known from EP-A1-0 229 860, consists of a fiber-reinforced material in which all fibers are unidirectionally aligned parallel to the tensile stress, with other fibers with particularly high tensile strength being inserted in the lower region of the lug.
  • the invention aims to provide a connecting strap made of plastic, which has higher strength and extended uses compared to the known design.
  • the connecting bracket according to the invention is characterized in that the same tensioning elements extend in the bracket body between the two end faces, via which the bracket body can be pretensioned.
  • the tensioning elements extend in the tension zone and in the Pressure zone of the tab body.
  • each tensioning element is formed by a wire made of metal or plastic, which is embedded in the tab body or guided in channels of the tab body and is held in the pretensioned state by anchor plates on the end faces of the tab body.
  • each tensioning element can be formed by a pre-tensioned tension wire embedded in the strap body, which is provided with projections on its outside and cut off on the end faces of the strap body.
  • the connecting straps can advantageously be adapted to the respective application with regard to the stresses to be absorbed, the bending strength of the connecting straps also being able to be increased significantly.
  • the connecting lug shown for the insulating connection of the butt ends of rails S, S ' has a substantially parallelepipedal, designed as a molded body tab body 1 made of plastic, which is provided in the embodiment shown with four through openings 2 for (not shown) connecting screws, which in the middle of the tab body height are formed.
  • the tab body 1 is reinforced on its outer side in the installed state by a rib 3 which extends over the length of the body from face to face. As shown in FIG. 1, the rib 3 is widened in the area of the passage openings 2 and in the middle of the tab over a substantial part of the body height, which is more than 50% of the height.
  • an adhesive layer of up to 2 mm in the web area and approximately 0.2 mm in the head and foot area is applied to the flap body on the side facing the flap chamber, and the flap is then screwed to the rails with high strength.
  • a fast-curing adhesive in particular methacrylate adhesive, is expediently used as the adhesive.
  • High-strength plastic which is reinforced in particular with glass fibers, is used as the material for forming the tab body 1, unsaturated polyester being particularly suitable.
  • tensioning elements 4 extend in the longitudinal direction of the flap body 1, which extend outside the through openings 2 from one end face of the flap body to the other, etc. in the tension and compression zones of the tab.
  • each tensioning element is designed as a smooth tensioning wire 4 made of metal or plastic, which is embedded directly in the pre-tensioned state when the tab body is cast.
  • the smooth tension wires 4 are cut off on the end faces of the tab body 1.
  • the smooth tensioning wires 4 can also be guided in channels of the bracket body 1 and, after the prestressing, can be held on the end faces by anchor plates (not shown).
  • the tensioning wires can be provided on their outside with ribs or other projections which ensure that the prestressed wires are anchored in the plastic within the scope of the adhesive length. These tension wires are also cut off at the end faces of the tab body after the shaping.
  • the tension wires can also be designed so that they are provided at predetermined longitudinal intervals with welded small disks that secure anchoring in the plastic. If plastic tension wires are used, they can be reinforced by embedded fiber material, such as carbon fibers, etc.
