Definitions

  • the invention relates to a dowel consisting primarily of plastic for fastening rails to prestressed concrete sleepers.
  • dowels in particular in the form of so-called shaft dowels made of plastic, which later hold the rail fastening screws, are used as built-in parts in the form of the sleepers during the manufacture of the sleepers. By concreting in, these dowels are then brought into close contact with the sleeper body.
  • the invention has for its object to provide a way to attach a dowel of the type specified, primarily a plastic plug, so in the formwork that it maintains its tight fit when pouring the concrete and vibrations by shaking that he but when applying the prestress to the sleeper, as long as it is still in the formwork form, the compression of the sleeper body is not impeded.
  • this object is achieved in that the dowel at the introducer for the rail fastening bolt has an attachment connected to the dowel body by a predetermined breaking point, by means of which the dowel can be positively connected to the bottom plate of the formwork which forms the threshold cover surface.
  • This approach expediently has a cylindrical shape; it can advantageously be inserted into a recess in the base plate.
  • the extension can have a barb gripping behind the base plate on the outer circumference.
  • the wall of the approach expediently has openings which can be designed as slots running in the direction of the surface lines of the approach.
  • the attachment can also have cam-like thickenings on the outer circumference, with which it can be inserted through corresponding enlargements of the bore in the base plate and can be locked by rotating it about its longitudinal axis in the manner of a bayonet catch.
  • the thickenings expediently have a shoulder intended for contact with the base plate.
  • the shoulder on the outer circumference can have a thread with which it can be screwed into a corresponding thread in the wall of the bore.
  • a cylinder socket can be inserted into the bore, in which the counter thread is arranged.
  • a seal made of an elastic material for. B. a rubber ring arranged.
  • the fastening device for the dowel is formed by an approach made of the same material as this.
  • This approach is integrally connected to the dowel when installed; this ensures particularly easy handling.
  • there is a predetermined breaking point between the dowel body and the fastening device which can shear under the compression caused by the pre-tensioning of the sleeper body, in any case no disturbing resistance to the compression opposed, so that this can run undisturbed and the dowel sits exactly in the intended position in the final state.
  • a threshold dowel 1 made of plastic which has 2 grooves 3 in the inner wall of the cylindrical dowel body for screwing in a rail fastening screw and profiles 4 on the outside for adhesion in the threshold body, is at its lower end 5 in the illustration in FIG. 1, the introducer for one Rail fastening bolt, integrally connected to a cylindrical extension 6 via a predetermined breaking point.
  • the predetermined breaking point 7 is formed in the exemplary embodiment shown by constriction on both sides in circumferential grooves; it can also be formed by one-sided constriction, by perforation or by a combination of these measures.
  • the wall 8 of the extension 6 is provided at the free end opposite the predetermined breaking point 7 with a circumferential, barb-like shoulder 9 which engages behind the base plate 10 of a formwork form and rests against its surface.
  • a sealing ring 12 made of rubber or the like is arranged between the lower end face 11 of the dowel body 2 and the surface of the base plate 10.
  • the dowel 1 is fastened in the form of the form by a hammer blow in the direction of arrow 13 from above onto the dowel 1.
  • a hammer blow in the direction of arrow 13 from above onto the dowel 1.
  • an annular compressive force arises in the extension.
  • the wall 8 of the extension 6 is provided with a number of longitudinal slots 15, which cause the cylindrical extension to deform radially inwards under the action of the annular pressure force and can slide through the bore 16 in the base plate 10.
  • the threshold dowel 1 is fixed in that the shoulder 9 engages in the elastic compression of the sealing ring 12 on the underside of the floor panel 10.
  • FIGS. 2 and 3 differ from those according to FIG. 1 in that the attachment 6a or 6b.
  • the corresponding mating thread is provided in each case in a cylinder connector 17, which extends the bore in the base plate 10 of the formwork in the axial direction.
  • the projection 6c has at its lower, free end two diametrically opposed cam-like thickenings 18, each of which has a shoulder 19.
  • the dowel 1 can be inserted with the extension 6c into the bore 16 in the floor plate 10 of the formwork, the thickenings 18 being guided through corresponding extensions 20 of the bore 16.
  • the dowel 1 By turning the dowel 1 in the direction of arrow 21, the thickenings 18 below the base plate 10 come out of the area of the extensions 20, so that the shoulders 19 rest against the base plate 10 from below and fix the dowel. A certain amount of tension can again be brought about by the elastic sealing ring 12.
