Definitions

  • the invention relates to a fastening element for fastening railroad tracks on a solid road, d. H. Rail fastening for ballastless Superstructure with the help of a hardenable mass.
  • the attachment according to the known solution is done in such a way that in a borehole of the subsurface filled with mortar a fastening element is used with an anchoring area. In the mouth area of the A centering sleeve is attached to the borehole.
  • the centering sleeve has on the circumference longitudinal grooves on when inserting the fastener displacing the mortar mass into the borehole.
  • an anchor is proposed here, which is essentially three Main sections, the threaded anchor fitting, a transition area that forms a transition cone and one Plug.
  • the anchor is in the borehole with the help of a destructible glass cartridge set.
  • EP-A-0713 014 is a by means of a curable mass in a borehole of a component fixable anchor bolt known, the anchoring part is formed by a cone bolt covered with a plastic jacket. On a pin arranged on the end face of the anchoring part is a Mixing head attached, which is detachably connected to the anchor bolt. Since therefore There is no fixed connection between the anchor bolt and the mixing head torque is not transmitted to the mixing head nor is the mixing head able to absorb tensile forces acting on the anchor bolt.
  • the ring-shaped for this purpose and offset to one another in the axial direction has arranged cams, hammered into the borehole. To put enabling the anchor bolt by hammering in is the amount and the Grain size of the tensile impact materials of the composite mass limited, so that due to the lower strength of the composite after curing result in lower holding values.
  • the invention has for its object a fastener for attachment train railroad tracks on a solid carriageway in such a way that on the one hand a good mixing of the compound mass in the rotation gear and on the other hand the mixing head for anchoring effect of the anchor bolt in particular also contributes to an increasing tensile load.
  • the Anchor bolts Due to the firm connection between anchor bolt and mixing head, the Anchor bolts are set in the rotation gear. Due to the helical shape Arranged ribs on the mixing head create the hardened mortar core in the Inclined surfaces engaging behind the borehole, which reinforce the anchoring effect of the Reinforce the anchor bolt arranged cones, especially when there is tensile load. The inclined surfaces and the cone also result in a spreading effect, that occurs when cracks occur, for example by squeezing in the solid carriageway can arise, compensates for the loss of shark strength. to The anchorage effect can be further improved over part of the Length of the bolt section may be profiled.
  • the invention is based on the embodiment shown in the drawing explained in more detail.
  • the anchor bolt 16 shown in FIG. 1 has a bolt section 10, which is provided with a profile 5 over part of its length.
  • the The front area of the anchor bolt 16 has a cone 6, which adjoins Mixing head 7 connects.
  • the mixing head 7 is arranged helically and radially projecting ribs 7b, the outer dimension of which is somewhat smaller than the borehole diameter in the concrete slab.
  • the between the ribs 7b Trained grooves 7a enable the anchor bolt 16 to be driven in Flow of the compound mass.
  • At the rear end of the anchor bolt 16 is one self-locking hexagon nut 30 on a corresponding connection thread screwed. Between the hex nut 30 and one over the Anchor bolt slipped centering bushing 3, a compression spring 2 is arranged, the serves as a biasing force element.
  • FIG 2 the fastening of a railroad track 14 is shown.
  • the rail 14 becomes a rib track plate 9 with a support plate 11 aligned on the concrete support plate 8 and through the mounting holes 15 of the Ribbed track plate 9 and support plate 11, the drill holes 17 in the concrete support plate 8 drilled.
  • the rail 14 is with tension clamps 12, which are clamped with a nut 1 are attached to the ribbed track plate 9.
  • the drill holes is the composite 13 in this by injection or by means of a Cartridge inserted.
  • the anchor bolt is set in the rotational gear, whereby the compound mass is mixed and the annular gap between the anchor bolt 16 and the wall of the borehole 17 is filled.
