Definitions
- the invention relates to a concrete sleeper for a fixed carriageway, with a dowel stone, which is inserted with its upper portion in a lower side recess of the concrete sleeper and elastically supported by means of a ring made of an elastomer and with its lower portion in a fillable recess of a cover layer of fixed roadway is used.
- a concrete sleeper for a fixed carriageway.
- the fixed carriageway comprises a lower support layer, a first applied asphalt layer and a second asphalt layer applied as a cover layer.
- the cover layer has recesses into which a dowel is inserted, which is thus arranged with its lower portion in the recess and with its upper portion in the lower side recess of the concrete sleeper.
- the concrete sleeper is designed as a broad threshold, d. H. between two adjacent concrete sleepers only a small distance is provided.
- Such a fixed track is offered by the applicant under the name Getrac (registered trademark).
- Getrac registered trademark
- the arranged between the concrete sleeper and the dowel elastic ring is conically formed on its outer side, whereby the insertion is facilitated.
- At the bottom of the concrete sleeper is a thin fleece to compensate for any unevenness of the top layer.
- Such solid roadways with elastic intermediate layers represent a mass-spring system can be transmitted by the vibrations and structure-borne noise to adjacent areas, buildings and structures. These waves can Both in the audible frequency range cause noise (secondary airborne sound) as well as cause vibrations of the floor or buildings. In the design of such a fixed track is therefore sought, the
- the invention is therefore based on the object of specifying a concrete sleeper for a fixed carriageway, by which vibrations are transmitted less strongly to adjacent areas.
- a sole made of an elastic material is arranged on the underside of the concrete sleeper.
- the invention is based on the recognition that a considerable improvement, i. a reduction of the vibration emissions can be achieved by the spring of the mass-spring system tolerated as tolerated superstructure as possible and the above the spring arranged mass is increased.
- a sole made of an elastic material is arranged on the underside of the concrete sleeper, whereby the mass (concrete sleeper) mounted on the spring (sole) is considerably increased compared to a merely elastically mounted rail of a conventional solid pavement.
- the sole of the concrete sleeper according to the invention may be made of an elastomer, particularly preferred being EPDM (ethylene-propylene-diene monomer).
- the sole may be loose or alternatively connected to the concrete sleeper, e.g. B. glued.
- the sole is designed according to static and dynamic requirements, in particular the thickness and the rigidity of the sole are dimensioned such that a required or desired
- the depressions can reach 1, 5 mm to 4 mm in such a sole.
- the sole may be provided on one or both sides with a fleece.
- a development of the invention may provide that the sole has a recess in the region of the lower-side recess for the dowel brick.
- this recess also at the threshold ends
- the dowel of the concrete sleeper according to the invention has a step with a downwardly enlarged diameter, wherein the outer edge of the step is preferably rounded. The rounded step prevents the ring made from the elastomer from being damaged by the millions of drop-in movements that occur during operation. Since no sharp edge is present at this point, unlike in the prior art, damage to the elastomeric ring is avoided.
- the width of the step of the dowel block can be so dimensioned that the ring rests approximately at half its radial width on the level of the dowel block.
- the underside recess of the concrete sleeper has a circumferential preferably rounded step, against which the ring abuts with its upper outer corner.
- the ring is approximately at half its radial width at the level of the concrete sleeper. This means that the ring, which has a quadrangular or approximately rectangular cross-section, on two diagonally opposite
- Corner points rests so that it undergoes shear deformation under load and deformed much like a parallelogram. This deformation is based on the one hand with its upper, outer corner at the level of
- the ring may be formed as a square, square or hexagonal enclosure.
- the ring is thus clamped at the concrete sleeper invention above and below, as he on the top of the step of the recess of the concrete sleeper and at the bottom of the dowel stone or rests. It is essential that the ring stored at the top on its outside and at the bottom on its inside
- the invention relates to a fixed carriageway, comprising several
- Base layer are embedded, wherein the cover layer or the support layer has on its upper side recesses for the dowel bricks, which are filled with a potting compound.
- Fig. 1 is a side view of a concrete sleeper according to the invention
- Fig. 2 is a plan view of the concrete sleeper of Fig. 1;
- Fig. 3 is a cross-sectional view of one in a fixed
- FIG. 4 shows a longitudinal section of the embedded in a solid roadway
- the concrete sleeper 1 shown in Figs. 1 and 2 in a side view and a plan view is formed as a broad threshold and comprises two
- Threshold blocks 2, 3 at the top rail supports 4, 5 are formed.
- the two threshold blocks 2, 3 are connected by a middle section 6
- the in this embodiment described broad threshold is not to be understood as a limitation, since the concrete sleeper can also have a different shape, such as a cuboid shape.
- the threshold blocks 2, 3 form with the rail supports 4, 5 and the central portion 6 an integral, monolithic component.
- Below the threshold blocks 2, 3 is in each case a sole 7, 8 arranged from an elastic material.
- the sole is made of EPDM (ethylene-propylene-diene monomer) and has a thickness of 14 mm.
- the specified thickness is not to be understood as a limitation, but the thickness of the sole can typically be between 6 and 20 mm, the sole thickness used is used in the context of the design of the stiffness and the
- the concrete sleeper 1 On its underside, the concrete sleeper 1 has in its middle section 6 an annular recess 9 into which a dowel block with an elastomeric ring can be inserted. When installed, the concrete sleeper 1 is above the
- Dowel stone coupled with the base course of a fixed carriageway, so that horizontal forces can be transferred to the ground. Vertical forces are introduced from the concrete sleeper 1 via the sole 7, 8 in the base course. At a fixed roadway, at least every second or third concrete sleeper is provided with a dowel.
- Fig. 3 shows the concrete sleeper 1 cut in the transverse direction in the region of its recess, after installation in a fixed carriageway.
- the concrete sleeper 1 has a plurality of reinforcing bars 10, 1 1, which may be limp or biased.
- a dowel brick 12 is arranged, which is secured with an assembly line 13.
- an elastic ring 14 which is made of an elastomer.
- the dowel block 12 has a step 15. Below level 15, the dowel brick 12 has a larger one
- the recess 9 of the concrete sleeper 1 has a peripheral step 17 with an outwardly enlarged diameter, at this stage 17 is the ring 14 with its upper outer corner.
- the step 17 is rounded as the step 15, whereby damage to the ring 14 is avoided under load deformation.
- Fig. 3 it is shown that the ring 14 approximately at its half radial width at the step 17 of the recess 9 of the
- an asphalt base layer 18 is provided with recesses 19 for the dowels 12.
- the recesses 19 are cylindrical and adapted to the size of the dowels 12, the depth of the recesses 19 is chosen so that below the dowel stone inserted together with the concrete sleeper, a free space 20 remains, the
- the concrete sleepers 1 have rail fastenings, which - unlike conventional fixed carriageways - are not highly elastic rail fastenings.
- the rail fastenings used allow compensation in height and lateral direction.
- the height compensation is made possible by documents of different thicknesses, the side compensation by angle guide plates of different widths.
