- the invention relates to a railway sleeper or slab track with at least one invention
- Screw anchor and an associated sleeper screw are screws anchor and an associated sleeper screw.
- Screw anchors for setting in concrete in a railway sleeper are used in railway construction to connect rail and sleeper.
- the rail fastening is over
- Screw dowels are often made of plastic and can be poured in the production of a concrete sleeper or a slab track in this.
- One reason for providing a plastic anchor is that an electric
- Screw anchor known in the cavity in a ring groove, a sealing ring is arranged.
- the sealing ring lies with a
- Threshold screw and prevents the ingress of
- the invention has for its object to provide a screw plug for the concreting in a railway sleeper and a railway sleeper or slab track with at least one such screw with an improved
- Threshold screw a threaded section with outside at
- the screw plug comprises a in the installed state near the dowel opening located upper section without
- the screw anchor is characterized that in the upper part of a high-quality material
- Elasticity is arranged, which extends in the installed state to form an upwardly projecting bead-like elevation beyond the plane of the dowel opening upwards and reduces the free opening cross-section of the interior of the upper portion.
- the material with high elasticity is thus not only in the interior of the dowel opening arranged to a
- Tolerance-related gap between sleeper screw and dowels seal but extends upward beyond the plane of the dowel opening, whereby when flush with the top of the threshold final upper portion of the anchor material with high elasticity extends beyond the top of the threshold upwards. In this way, a barrier is created, which prevents water located on the top of the threshold in the
- the material with high elasticity is a separate component, which is attached to the upper portion. It may thus be the material with high elasticity to a sealing ring, which in a suitable manner with the upper
- Part section is connected, such as glued or welded to this.
- the separate component has a dovetail-shaped projection which engages positively in an annular groove on the upper portion. In this way, the
- Material is sufficiently compressible to be inserted into such a groove, to widen it again and to be held positively in the groove.
- the separate component is mounted on the upper section.
- the provided as a separate component material can be expanded with high elasticity and attached as a sleeve on the upper portion and holds
- the material with high elasticity is molded onto the upper section. In this way, the assembly costs can be further reduced, but are higher
- the external thread is a round thread, which has proven to be very favorable in terms of adhesion at radial stresses between dowels and concrete material.
- erdübel further at least one provided in the longitudinal direction outside of the screw plug positive-locking element
- Positive locking elements serve to prevent undesired rotation of the screw plug relative to the concrete sleeper and contribute to the reliability of the invention
- the material is high in elasticity
- the railway sleeper or slab according to the invention with at least one screw anchor according to the invention is designed so that the force engagement between the sleeper screw and dowel is displaced into the deeper dowel area and accordingly also in the deeper area of the threshold or slab track. In this way the tension can be reduced.
- Screw anchor has a widening towards the insertion opening conical area. In this way, the engagement between the thread of the sleeper screw and the screw plug is displaced into the lower region of the plug, i. in the deeper dowel area, further from the
- Insertion hole is located away.
- the sleeper screw so that it has a first and a second cylindrical portion.
- the first cylindrical portion has a larger core diameter than the second cylindrical portion and is closer to the screw head than the second cylindrical portion.
- the core diameter is understood to mean that diameter which is defined by the deepest thread grooves.
- a third possibility is to reduce the force engagement by the design of the dowel thread, e.g. by the
- Figure 1 shows a first embodiment of a
- Figure 2 shows a second embodiment of a
- Figure 3 shows a third embodiment of a
- Figure 4 represents a screw according to the invention with screwed-in sleeper screw
- Figure 5 shows an alternative design of a
- Threshold screw for use with a screw according to the invention shows.
- the screw plug 10 shown in Fig. 1 consists of
- Plastic material is divided into several sections. These are, for the first, a lower partial section 12 with a substantially cylindrical shape, a threaded section 14 and an upper partial section 16. In the region of
- Threaded portion 14 are numerous threads 18, which in the area of the external thread as a round thread
- an internal thread 19 which may also be designed as a round thread, but may differ from the external thread 18 with respect to the thread pitch and thread pitch.
- the upper portion 16 is substantially cylindrical in shape and formed integrally with the threaded portion 14 as well as the lower portion 12.
- form-fitting elements may be provided in the form of running in the longitudinal direction of the screw dowel ribs 20, which after encapsulation of the screw with the concrete mass of a railway sleeper or festivals
- the screw plug shown in Fig. 1 is with a
- Sealing member 22 is provided which extends from the upper end surface 24 of the upper portion 16 upwards. When the end face 24 is flush with the top of a
- Seal member 22 above the top of the threshold also upwards.
- the sealing element 22 also narrows the opening 26 of the
- Screw anchor so that after screwing a
- Threshold screw is applied.
- the extension of the sealing element 22 is from the
- the sealing element 22 has a dovetail-shaped annular ridge 30 which engages positively in a dovetail-shaped annular groove 32 in an upper flange portion of the upper portion 16.
- the sealing element 22 is made of a material with a high
- Threshold screw in the screw plug can adapt to the outer contour of the screw and can be applied to this.
- the sealing element 22 extends over the
- top end surface 24 and thus can not only the ingress of moisture and dirt in the
- Screw anchor with inserted threshold screw prevent, but already as an overcurrent barrier for on the
- Threshold top serve accumulated water.
- Fig. 2 corresponds substantially to that of Figure 1, but differs by the design of the sealing element 22.
- the sealing element extends to the top side
- the advantage of the provided on the outer circumference cylindrical skirt 38 is that they inevitably occur in a concrete sleeper Compensate for contractions and helps prevent radial stresses with any radial cracks go out of the dowel.
- the sealing element 22 bulges at radial pressure upwards and forms there as an overcurrent barrier for accumulated on top of the threshold or slab track water.
- the attachment of the sealing element shown in Fig. 2 can be done in different ways. On the one hand, a positive connection as shown in Fig. 1 between the upper portion of the dowel and the sealing element may be present. Alternatively, it is also possible that
- Sealing element offers the possibility of not only the
- Concrete threshold to extend and thus to provide an overcurrent barrier for water on the concrete sleeper.
- Embodiment of FIG. 2 exist with respect to the Providing a cylindrical skirt 38, which is designed in one piece with the sealing element 22.
- the correspondence with the embodiment of FIG. 1 is with reference to FIG.
- Opening cross-section 24 which is less than the cylindrical inner wall 28 of the upper portion 16.
- the sealing element extends over the end face 24 upwards and thus also forms the not yet compressed
- the screw anchor 10 each have a in
- FIG. 4 differs from the embodiment of FIG. 4, in which the portion 16 of the screw plug has no cylindrical shape, but is widened conically towards the opening 26.
- the sealing element 22 shown in Fig. 4 substantially corresponds to that of FIG. 3, wherein it can be seen that the elastic deformation of the opening 26 in the
- the screw 50 has a screw head 52 with a
- Section 14 of the anchor into engagement with the internal thread 19 of the anchor, whereas in the conically widening
- Section 16 of the anchor 10 the screw thread 58 only slightly or not at all touches the inner wall of the dowel. In this way, the force engagement between the sleeper screw and the surrounding dowel is displaced into the deeper dowel area 14 to the near-surface To reduce stresses in the threshold area or in the area of the slab track.
- Screw thread is substantially cylindrical, but the surrounding dowel is widened.
- the sleeper screw can be designed so that the thread is provided only in a certain area of the sleeper screw, whereby also the force engagement between the sleeper screw and dowels can be moved to the deeper dowel area.
- the threshold screw shown in Fig. 5 is an example of this and has several sections. A first cylindrical portion 60 connects to the
- Screw head 52 has no external thread.
- the first section 60 merges via an intermediate section 62 into a second section 64, which is also cylindrical, but in some areas threaded elevations 66 of the
- External thread 58 has. If the receiving dowel is shaped correspondingly to the threshold screw 50 shown in FIG. 5, it is clear that the threads 66 only engage in a corresponding internal thread of the dowel in the lower region of the dowel, whereas the first section 60 engages on a smooth, i.e. not provided with an internally threaded wall of the dowel. This measure also serves to shift the force intervention in the deeper area of the anchor and thus the surrounding threshold or slab track. All embodiments have in common that by the
- Design of the anchor is a seal upwards and inwards, resulting in the electrical resistance of the
