Definitions
- the invention relates to a turnbuckle for connecting Wegankem after the Preamble of claim 1.
- a ballastless track for rails on where rail vehicles drive, with adjacent deck plates, it is customary to brace the road slabs by means of tie rods against each other.
- the Tie rods usually extend through the adjacent deck plates.
- At least the ends of the tie rods have an external thread. turnbuckles connect the ends of the adjoining tie rods.
- EP 0 516 612 A1 shows a ballastless superstructure. From Concrete manufactured slab panels and their breakthroughs for receiving the Tie rods have tolerances. In addition, the road plates can not always straight and in a plane next to each other, there curves and elevations the railway are provided. This has the consequence that in the past used turnbuckles the flat screw supports for the clamping nuts cause disadvantageous that the tie rods acted on the clamping with bending forces be, which in extreme cases even to a plastic deformation of the ends the tie rod leads.
- the invention is based on the object, a turnbuckle for connecting tie rods nachzusenten according to the preamble of claim 1 such that it on End of the tie rods no longer comes to constraints or bending.
- any Mounting positions of the carriage plates and also large manufacturing tolerances are not affect more on the connection of tie rods. It can be ensured that the tie rods are charged only with pure tensile forces, making this one get longer life. Furthermore, it is advantageously achieved that the tie rod after tightening no longer laterally through the slot from the turnbuckle can slip out.
- the turnbuckle 1 is formed like a chain link. It has a thin cross section in the middle region. At the ends 2, to which the tie rods 3 are fixed, a larger cross-section is provided. In this area bearing surfaces 4 are arranged for the nuts 5 indoors.
- the tie rods 3 are formed at least at their ends 6 with an external thread, which cooperate with the nuts 5, so that the nuts 5 a Clamping the tie rods 3 takes place.
- the ends 2 of the turnbuckle 1 are extending laterally outwardly with it Slits 7 formed. Through these slots, the tie rods 3 can be inserted laterally are already wearing at their ends 6, the nuts 5.
- the support surface 4 on the turnbuckle 1 spherical is convex.
- the nut 5 is located on the flat counter surface 10 of the disc 8. Misalignments of nuts 5 due non-aligned tie rods 3 or other manufacturing and dimensional tolerances can now by moving the spherical concave contact surface 9 of the Disc 8 on the spherical convex bearing surface 4 on the turnbuckle 1 in a simple Be compensated.
