Definitions

  • the invention relates to fixed carriageways for rail-bound traffic, as described in the preamble of claims 1, 23 and 36.
  • Rail-bound traffic requires firm carriageways, for example for high-speed lines where particularly high demands are placed on the positional stability and, in turn, particularly on the stability against lateral shifting of the tracks, which cannot be achieved with conventional ballast bedding of the track.
  • the sleepers must at least in the direction of the longitudinal axis of the sleeper - i.e. transversely to the track axis - be elastic but immovable.
  • the track should also be kept vertically movable on the base course in defined bearings, in order to prevent vertical relative movements between the base course and the sleeper, which occur every time the track is traveled by elastic deformation of the intermediate layer between the sleeper and base course, but also due to the rail deformation from the forward and backward Trailing wave are possible to be able to record harmless in the long run.
  • the potting of the space between the threshold and the shear force base does not guarantee permanent vertical mobility. There is a risk that the potting will become brittle due to aging. The indispensable horizontal dowelling would be at least endangered in the long run. It is difficult to check or re-shed the space due to its restricted accessibility. A non-destructive lifting of the track grate in the event of a repair is not possible due to the gluing of the threshold and the shear force base. It is not possible in practice to manufacture the transverse force base with a precise fit.
  • the object of the invention is to eliminate all or part of the above-described defects of the known solid carriageway in various proposed solutions, but at least to further develop and improve the known solution.
  • Claim 1 describes a fixed roadway in which individual, dowel-like devices are provided for at least some of the sleepers, each holding the threshold separately.
  • Claim 23 describes a solid roadway in which the dowel-like device, which keeps the sleeper horizontally immovable on the base layer, is a prefabricated and can be formed on the sleeper - expediently already during its manufacture - cone-shaped element.
  • the vertical mobility is achieved with a vertically slidable elastomeric shoe cast into the recess of the base layer.
  • Claim 36 describes a fixed carriageway with dowel-like devices in the form of ribs formed integrally with the base layer, between which the sleepers are held in their axis in a non-displaceable but vertically movable manner.
  • Anchors according to claim 10 can be made of different materials, e.g. Concrete, synthetic resin, steel or ceramic can be made.
  • Claim 35 gives a proposal for an economical use of dowel-like devices in a solid roadway.
  • the dowel-like devices holding the sleepers in their longitudinal axis only have to be arranged in the number on the track that corresponds to the expected horizontal forces acting on the track. It can therefore suffice to provide only individual sleepers, expediently at the same distance, between sleepers without dowelling. In the case of biblock sleepers in particular, the arrangement of the device alternately at one of the two ends of the threshold is recommended.
  • Dowel-like devices that can be mounted on the outside of the threshold, as described, for example, in claims 30-34, are also suitable for rigidly and immovably fixing the track in the desired position for a limited period of time until the grout hardens sufficiently is.
  • the vertical mobility between the threshold and the base layer has to be temporarily suspended on the corresponding device parts - for example, by screwing to the adjacent components threshold (claims 30, 33, 34) or base layer (claim 31). Changes in the track axis during assembly - for example due to temperature jumps - can be prevented in this way. After the grout has hardened, the screw connections are loosened and the dowel-like devices can work in the intended manner.
  • standard thresholds are of great economic importance for the solid carriageway. Without any change, standard thresholds can be used on a solid roadway according to claims 36 u. 37 can be used.
  • the disadvantage of this solution is the trough between the rib-like ribs running alongside the sleepers as a device 7, which has disadvantages for drainage.
  • dowel-like devices have sufficiently small cross-sectional dimensions, they can be arranged in closed recesses in the sill, which still leave sufficient concrete cross-section laterally in the longitudinal axis of the sill to carry out prestressing rods therein. In the case of the sleepers used for the solid carriageway, construction height can then be saved.
  • Advantageous solutions for devices that easily meet these conditions are primarily oar-shaped devices according to claims 24-29.
  • the tube sleeve in which the oarlock of a oar-like dowel is guided, is appropriately closed with a lid after installation of the dowel to protect it against the ingress of day water.
  • a continuous slot in the threshold will generally be expedient, which causes a reduction in the static height of the threshold in the slot area and thus necessitates an increase in the threshold height. This may to increase the threshold weight and to stabilize the track position.
  • a slot also gives the possibility, particularly important for dowel bodies according to claims 13-20, of inspecting the deformation bearings and possibly carrying out repairs without having to lift the track for this.
  • a useful embodiment of the invention is measures by which a time-saving, economical final assembly is achieved.
  • Such a measure is the pre-assembly of the dowel body on the threshold according to claims 21 u. 22.
  • Another expedient embodiment is a solid roadway according to claim 5 and 5/1. It may be useful for economic or technical reasons - for example in the case of engineering structures, such as bridges - to run solid roadways over base layers made of concrete or steel, in which the production of recesses is difficult for the dowel-like devices.
  • the recesses for anchoring the dowel bodies can expediently be worked into the base layer with the aid of known cutting methods in an advantageously likewise fully mechanized operation immediately preceding the rail laying train.
  • a groove-shaped recess is provided in the base layer, it enables the sleepers to be arranged without restrictions, regardless of any changing sleeper spacings, e.g. in curves or in turnout areas, - measures to save complex casting compound for casting the dowel-like devices are a determining factor for the economy of the tramway construction.
  • Filling bodies inserted into the recess in the area between the threshold dowels serve to save potting compound. These are poured in with a simpler hydraulic mortar, which can also be used for everyone to pour out the recess in certain areas. In order to ensure that the filler body flows around on all sides through the high-quality mortar and thus prevent the ingress of day water, the filler bodies can be provided with warts as spacers. It is also possible to seal these areas with asphalt.
  • Full flow around the dowel body with grout according to claim 7 can be ensured by convex or concave design with ventilation channel of the bottom surface of the dowel body in the recess, the quality of the integration of the dowel body in the recess by roughening and / or profiling the side surfaces of the dowel body and / or recess as well as by spraying on an adhesion promoter.
  • the solid carriageway according to the invention is based on the base layer 1 with an essentially flat surface 2 on which monoblock sleepers 3 (FIG. 1) or biblock sleepers 10 (FIG. 2) can be laid.
  • the thresholds 3, 10 lie in the regions 4 on flexible compensation layers 6 on the base layer 1. Between the regions 4, the region 5 extends under the sole surface of the monoblock threshold 3 in which the threshold 3 does not rest and forms an open joint 18.
  • this area is particularly suitable for a central arrangement of dowel-like devices 7.
  • the devices 7 are expediently arranged in the area of a block 11.
  • the dowel-like devices have the task of introducing the horizontal forces acting transversely to the same axis from the track into the supporting layer 1 and of keeping the threshold 3, 10 against lateral displacement.
  • the devices 7 have a lower part 8, which is anchored non-positively in the support layer 1, and an upper part 9, which holds the threshold 3, 10 like an abutment against displacements in the longitudinal axis of the threshold. Since the track can perform vertical movements while driving, the threshold 3, 10 is expediently held vertically movable by the upper part 9 of the device 7.
  • the devices 7 can be anchored in the base layer in different ways.
  • Bolt-like devices 14 can be fastened directly into the base layer using drilled dowels (Fig. 35) or driven-in (Fig. 34). They can also be cast in prefabricated trough-shaped continuous or locally limited recesses 12 or 13.
  • fillers 59 can be inserted in the sections 58 between the connections of devices 7 with low-quality mortar for closing in the channel-like recess 12.
  • the fillers can have wart-like projections 81 in order to achieve a solid encapsulation of the filler.
  • the oar-like devices 7 are expediently guided in sleeves 15 in the threshold 3, 10.
  • the oarlock 14 is driven through a recess 48 into an expansion dowel 45.
  • the jaws of the expansion anchor 45 are pressed against the side surfaces of the recess 12, 13 and thus anchor the oarlock. Then a sleeve 15 is pushed over the oarlock, the sleeve is poured with grout 49 and protected with a lid 17 against the ingress of day water. A foam pad 16 can also be inserted between the oarlock and the lid. Between the oarlocks 14 and the sleeve 15, a leading elastic sleeve 50 can be inserted, which improves the lubricity of the bulge in the sleeve. 30, a dynamic force-damping elastic sleeve 50 is arranged on the outside around the sleeve 15. The sleeve 15 itself can be made of elastic damping material.
  • FIGS. 28 and 29 show a oar-like device 7 which can be preassembled.
  • the oar 14 anchored in an anchor body 28 has a length slightly exceeding the height of the threshold 3, 10. It is inserted from below through the sleeve 15 until its upper end, which is provided with a bore 26, emerges from the sleeve. With the help of a split pin 27, the device is held in this position until the final assembly and is lowered during the final assembly by loosening the split pin into the recess 12, 13 and cast with mortar 29.
  • FIGS. 34 and 35 show examples of oar-like devices 7 anchored directly - without previously produced recesses 12, 13 in the base layer 1.
  • an oar 14 with its lower part 51 is inserted into the base layer 1 by means of a threshold 3, 10 provided sleeve 15 driven.
  • the upper part 52 of the doll 14 slidably holds the threshold in the sleeve.
  • the sleeve is closed with a cover 17.
  • the threshold is pegged in the support area 5.
  • the surface 2 of the base layer 1 can bulge out at the point of penetration of the ball 14.
  • the compensation layer 6 is left out at point 53.
  • the threshold can be trough-shaped.
  • the dowel is anchored with its lower part 51 in the base layer 1 with a drilled-in adhesive dowel.
  • Devices 7 can be cast as dowel bodies 19 (FIGS. 11-15).
  • the dowel body 19 is poured through the pouring channel 23 in the threshold 3. It is formed by the recess 22 in the threshold, the space of the joint 18 under the sole surface 44 of the threshold within the sealing strand 20 and the recess 13 or the space of the recess 12 delimited by formwork 21.
  • the upper boundary surface must be 72 of the recess 22 can be covered with a flexible cushion 73 so that the dowel body 19 can move vertically in the recess without hindrance.
  • a displacement body 24 can be inserted into the cavity for the dowel body 19.
  • a further embodiment of a device 7 is a prefabricated dowel body 30. It can be produced in a simple cubic form (see pattern shapes in Fig. 31 / 1-6). With its upper part it engages horizontally non-positively, vertically movable in the recess 22; with its lower part it is firmly cast into the base layer.
  • FIGS. 15-21 A preferred embodiment of the dowel body 30 is shown in FIGS. 15-21. With its side surfaces 33, the upper part 31 springs back relative to the side surfaces 36 of its lower part 32.
  • the recess 22 is expediently designed with conically widening side surfaces 34.
  • a deformation bearing 35 was clamped in the space 37 bounded laterally by the surfaces 33 and 34 and below by the recess 41. Its elasticity allows vertical movements of the dowel body 30 in the space of the recess which is kept free above it, while the dowel body is held in the recess 22 horizontally non-positively.
  • the recess can be a continuous slot 74.
  • the dowel body 30 expediently has an approximately longitudinal rectangular shape.
  • the deformation bearings 35 are then only required on the sides 75 of the slot running transversely to the longitudinal axis of the threshold.
  • the sections 43 of the deformation bearing 35 which bear against the sides 75 are connected by webs 87.
  • Good quality of their composite in a recess 12, 13 is important for the effectiveness of the dowel bodies 30.
  • This can be additionally improved by suitable known measures such as adhesion promoters, profiling or roughening of the side surfaces of the recess 12, 13 and the lower part 32 of the dowel body 30 and in that the part 32 is fully surrounded by grout.
  • suitable known measures such as adhesion promoters, profiling or roughening of the side surfaces of the recess 12, 13 and the lower part 32 of the dowel body 30 and in that the part 32 is fully surrounded by grout.
