Definitions

  • the invention relates to a track superstructure and substructure for rail-bound vehicles, rails being detachably connected to the rail foot directly or indirectly, preferably via intermediate plates, with sleepers which in turn rest on the ballast bed on the ground.
  • ballast-free track substructure and superstructure In the case of track support structures, a distinction must be made between two fundamentally different superstructures. between the conventional structure with the ballast bed and the so-called ballast-free track substructure and superstructure.
  • the ballastless construction usually consists of an in-situ made concrete support block, which can have steel reinforcement, on which either support plates or sleepers rest.
  • the interposition of a leveling layer is provided, which should not only bring about the leveling, but also ensure the uniform transmission of force between sleepers or carrier plate and in-situ concrete.
  • This power transmission should, for example, only transmit vibrations in a damped manner.
  • it is necessary that a certain deflection of the rails occurs when loaded by the rail vehicles. This deflection can either be achieved by an elastic mounting of the sleepers, for example by rubber loafers or the like, or or in addition, an elastic intermediate layer can be provided under the rails.
  • ballastless superstructure many developments have been made in the field of ballastless superstructure, in particular a smaller one Construction height is possible and for constructions in which a stationary concrete body already exists, such as bridges or tunnels, almost maintenance-free operation is possible.
  • the further advantage of the so-called ballastless superstructure is that it has lower overall heights and thus allows tunnels, if the ballast bed is removed and a ballastless superstructure is provided, to transport higher goods on normal wagons, especially containers, truck bodies and the like, without expanding the tunnel profile .
  • a superstructure with gravel As it would be possible with a superstructure with gravel.
  • the development work, especially for high-speed railways, of the ballastless superstructure has been particularly advanced.
  • Thresholds for a substructure with ballast are exposed to particularly high loads.
  • sleepers consist of well-dried oak wood, which is impregnated before use, especially with tar products, so that it is particularly resistant to weathering and microbiological attack.
  • the rails are usually connected to the threshold by so-called rail nails.
  • the threshold as such has a sound and shock-absorbing effect.
  • Wood is also particularly polluting when it comes to processing wooden sleepers that are no longer usable. These wooden sleepers cannot be burned easily since they burn a large number of extremely polluting exhaust gases.
  • the present invention has set itself the task of creating a track superstructure and substructure that has good sound-insulating properties, at the same time a displacement of the sleepers on the ballast bed is particularly effectively prevented, and in which normal maintenance of the ballast bed, for example by track tamping machines, can be carried out.
  • the concrete sleepers are each connected to at least two rails and rest on a ballast bed on the ground, consists essentially of it that the concrete sleepers have at least one coating on their surfaces exposed to the ballast bed, which with rubber-elastic materials, for. B. rubber, polyurethane or the like., Is constructed and is at least partially adhesively bonded to the surface of the concrete sleeper.
  • the power transmission between the wheel and the ballast bed is in any case damped, so that especially high-frequency vibrations, which lead to premature undesired settlement of the ballast bed, are only passed on with lower force peaks, so that the service life of a ballast bed can be increased.
  • a coating significantly increases the displacement resistance of the sleeper on the ballast bed compared to an uncoated concrete sleeper, so that a longer service life is also guaranteed in this regard.
  • the maintenance work on the ballast bed can be carried out with the usual track tamping machines, since neither foils od. Like. Are provided in the ballast bed, which are destroyed immediately when tamping. Another advantage is that vibrations in the audible range are only passed on in a damped manner, so that a lower environmental impact due to sound emissions is also guaranteed at the same time.
  • the preferred layer thickness is between 1 and 5 mm, in this area, on the one hand, there is an optimum service life of particularly favorable values for sound insulation and high resistance to displacement of the concrete sleepers on the ballast bed. If this coating is provided over the entire surface, then the sound emission of the concrete sleeper with respect to the air is also still considerably reduced, with no additional work being required during production.
  • a multilayer coating is provided, a particularly good optimization of the properties can be achieved.
  • a coating with a high resistance to tearing and tear propagation can be provided on the surface which is in direct contact with the ballast bed, so that the subsequent layers or layer can take on other properties.
  • a layer can be provided which has a particularly high sound insulation and a further coating can be provided which has a particularly high internal damping during the transmission of impacts that lead to premature disruption of the ballast bed.
  • the coating has a film
  • prefabricated materials can also be used, whereby particularly simply only at the preferred locations, e.g. B. on the lower contact surface, such coatings can be provided, thus enabling anisotropic properties of the threshold.
  • an adhesive in particular an adhesion promoter, can be provided between the coating and the concrete sleeper.
  • the coating is a coating applied by spraying, particularly good control of the thickness of the coating can be achieved, both particularly uniform coatings in the layer thickness and with a continuous transition being able to be achieved, as a result of which the service life of the coating can be significantly increased.
  • the coating is a coating applied by dipping, a particularly uniform coating with continuous transition areas can be achieved, for example, by dipping once. Furthermore, there is the possibility that by immersing the coatings which have not yet fully set, a particularly intensive anchoring of individual layers in one another is achieved.
  • a particularly advantageous embodiment which ensures a uniform property profile even at lower temperatures, is that the coating with a hydraulic binder, especially cement, for. B. Portland cement, a plastic with a T ⁇ max value, determined according to DIN 53 445, of at most - 8 ° C and optionally with fillers is constructed.
  • a hydraulic binder especially cement, for. B. Portland cement, a plastic with a T ⁇ max value, determined according to DIN 53 445, of at most - 8 ° C and optionally with fillers is constructed.
  • Such coatings even at low temperatures, still have the desired viscoelastic properties, at the same time giving the coating particularly good adhesion to the concrete sleepers and also allowing the coating to heal or reconnect the layer to the concrete sleeper during operation.
  • the coating has pores, in particular closed pores, then on the one hand an additional possibility for changing the spring characteristic of the coating can be achieved, wherein, in particular with closed pores, the sound-conducting behavior can be influenced, for example.
  • the coating has fillers, e.g. B. stone flour, a significant change in the specific weight of the coating can be achieved, whereby both changes in the spring characteristics, for. B. by providing rubber-elastic fillers, such as rubber scrap or the like., Or by increasing the mass, to thereby achieve a change in the sound conducting properties.
  • fillers e.g. B. stone flour
  • the threshold is also at least partially coated on the surfaces not impacted by the ballast, sound radiation through the thresholds can be avoided in a particularly advantageous manner, while the coating can also serve as a vibration-damping underlay under the rail fastenings with appropriate mechanical properties.
  • the threshold 1 shown in FIG. 1 is constructed from a concrete B 400 and has a double prestressed reinforcement 2 and 3. For the sake of clarity, no coating on the threshold is shown.
  • the threshold 1 made of concrete shown in FIG. 2 has two channels 4 and 5, each of which is guided in a cross and in which, after the concrete has at least partially hardened, a steel reinforcement 6, 7 is provided, which is prestressed.
  • a component can be pre-stressed by the reinforcement in the present case, a threshold made of concrete is provided with compressive stresses, so that the compressive stresses are first released when tensile stresses are applied.
  • Such pre-stressing of components is always desirable when there are large differences in the properties of tensile stress and compressive stress.
  • plastic dowels 8 are also provided, which cooperate with rail nails 9.
  • the rail 10 rests on the angle guide plate 13 with its foot 11 via an intermediate layer 12 made of rubber-elastic material. Under the angle guide plate 13, an intermediate plate 14 is also made of rubber-elastic material.
  • the rails are held against the threshold via the rail nails 9 and the tensioning clamps 15.
  • Each threshold has at least two rails, the thresholds being designed as continuous thresholds which have a substantially constant cross section over their entire length.
  • the layer thickness is 3.5 mm.
  • the coating was applied by spraying and has a Shore hardness A of 73.
  • the coating consists of a polyurethane which is composed of a polyether polyol (Baytec FP PU 0308 from Bayer) and a modified 4,4 / -diisocyanatodiphenylmethane (Desmodur PU 0309 from Bayer). Between the concrete sleeper and the coating, an adhesion promoter, also based on polyurethane, is provided dissolved in a solvent, which is applied thinly. After the solvent has evaporated, the coating can be applied.
  • a slack reinforcement 20 made of rib steel is provided.
  • the concrete sleeper is provided with a full-surface coating 21 with a thickness of 2 mm, which has a further coating 23 on the coating 21 on its bottom surface 22.
  • the coating 21 corresponds in its composition and application to the coating 18 according to FIG. 1, whereas the coating 22 chemically corresponds to the coating according to FIG. 1, but this further coating was applied by knife coating, as a result of which the further coating is about 20% higher Has a density (1.1 mg / m3) than the coating applied by spraying.
  • the tear propagation resistance (measured according to DIN 53 515) is approx. 10% greater than when processing by spraying (16 kN / m). On the one hand, this significantly increases the durability of the coating on the floor surface, and at the same time there is a higher resistance to displacement.
  • a slack reinforcement 20 is also provided, with a triple coating, u. between a layer 18 of sprayed polyurethane with a thickness of 2 mm according to FIGS. 2 and 3, a further layer 24 also made of polyurethane, but applied by dipping with a thickness of 2 mm and an outer coating 25 made of a film with a thickness of 0.5 mm, which was obtained by hot pressing a polypropylene nonwoven, which was mechanically applied to the still moist further layer 24.
  • Such a structure for the coating of a threshold is more labor-intensive, however, due to the lower density of the sprayed coating, for example, the sound transmission can be better inhibited, whereas the dipped coating made of polyurethane has a higher mass and accordingly has better mechanical damping properties and the hot-pressed polypropylene nonwoven film has a particularly high strength due to the disorientation of the fibers of the random fiber fleece and both the mechanical stresses during operation, in particular by lateral forces, and the mechanical stresses the stuffing of the ballast bed can be taken into account particularly cheaply.
  • the concrete sleeper shown in FIG. 5 has a coating of polyurethane in a layer thickness of 3 mm on its surfaces acted upon by the ballast bed. A continuous transition of the coating to twice the layer thickness is provided on the beveled surfaces 27, so that the surface 28 is provided with a layer 26 with 6 mm.
  • These coatings can have a multi-layer structure, with particular preference being given to coatings made of a material which have particularly high damping, such as polyurethanes.
  • the layer can also be applied here by dipping, spraying, knife coating, gluing.
  • Concrete sleepers were each provided with two rail nails, which in turn served as a handle for diving, the concrete sleepers equipped in this way in a suspension with 100 parts by weight of cement and one aqueous dispersion of plastic and a filler, e.g. B. stone flour, were dipped.
  • a filler e.g. B. stone flour
  • the plastics used were a styrene-butadiene polymer with 50 parts by weight and a T ⁇ max value according to DIN 53 445 of -70 ° C or 120 parts by weight of butyl acrylate with a T ⁇ max value of + 18 ° C or 5 parts by weight of an acrylic butyl ester with a T ⁇ max -Value of - 46 ° C or 100 parts by weight of an acrylic butyl ester with a T ⁇ max -Value of - 46 ° C.
  • Coatings of this type are distinguished by particularly good sound insulation, and at the same time, even after tamping, if, for example, the coating is partially detached from the threshold, this coating becomes adhesive again with the threshold connects.
  • All sleepers designed according to the invention have a significantly higher displacement resistance on the ballast bed than they correspond to conventional concrete sleepers, so that a particularly high stability against displacement is guaranteed, particularly in the curves. It was completely surprising that sleepers designed in accordance with the invention also survive the mechanical tamping process with tamping machines, even after a 5-fold tamping process, essentially with unchangeable operational properties. This behavior was surprising in itself, but it should be due to the fact that the coating is elastic and thus during the tamping process, for example when a large gravel grain is pressed into the ground along the side surface of the sleeper, the coating can dodge due to its elastic properties , so that only a minor injury occurs.
  • the fillers are not only stone powder, but also other fillers, such as rubber granules and, depending on the desired changes in properties, vermiculites and pearlites and the like. Like., in question.
  • foils u.
  • outermost layer but also as the middle and innermost layer
  • perforated, foamed, extruded films can also be used, depending on the desired range of properties.
