Definitions
- the present invention relates to a method for fastening rails to a concrete body by screwing, at least one steel plate and at least one electrically insulating layer being laid between the rail foot and the concrete body, and to the lateral guiding forces of the rails and the steel plate connected to them be picked up by a practically vertical, outside upstand of the concrete body. Furthermore, the invention relates to a device for fastening rails on a concrete body by screwing, at least one steel plate and at least one electrically insulating layer being present between the rail foot and the concrete body.
- the rail is laid on a ribbed plate, which connects the rail to the wooden sleeper using a tension clamp, sleeper screw and washer.
- the rail is connected to the ribbed plate by means of a tension clamp, hook screw washer and nut.
- the ribbed plate is then connected to the wooden sleeper with sleeper screws and spring washers.
- the parts used for this have been standardized for years and are available practically everywhere and at any time.
- a threshold which consists of two concrete blocks.
- the concrete blocks have raised edges, whereby there is a material between the raised edge and the support plates. that is, which is permanently elastic and should transmit the forces from the rail to the concrete block. It is obviously an elastic steel band.
- the invention has for its object to provide a method for laying and fastening rails on a concrete body by screwing, in which at least one steel plate and an electrically insulating layer are in turn present between the rail foot and the concrete body, but in which the special bead in the concrete body and the special angle guide plates can be dispensed with, and yet the cornering forces from the rail can be reliably transferred to the concrete, thanks to a practically vertical, upstand on the outside.
- the invention has set itself the task of reducing the sound and vibration transmission from the rail to the ground and thus to the environment and to increase the safety of the installed rail track, especially in the event that the screw connection to the concrete body has loosened or even pulls out or breaks.
- the attachment should preferably take place in such a way that a shock-absorbing spring-back takes place.
- the device according to the invention for fastening rails to a concrete body by screwing, with at least one steel plate and at least one electrically insulating layer being present between the rail foot and the concrete body is characterized in that the concrete body has a practically vertical upstand on the outside, which has the Lateral guide forces of the rails and the steel plate connected to them and that a plastic layer is present between the steel plate and the lateral upstand, this plastic layer preferably completely filling this space.
- this can be done using U-profiles of different thicknesses. In particular, if these are thermoplastically deformable, this U-profile can then be connected to the steel plate by briefly heating from both ends in such a way that the material can no longer slip.
- plastic wedges Similar measures are of course also possible when using plastic wedges, provided that they are thermoplastic. If the space between the upstand and the steel plate is cast with a multi-component resin, a part that cannot be moved is obtained anyway. In addition, it is also possible in principle to design the electrically insulating plastic base so that it encompasses the steel plate resting thereon.
- a ribbed plate on an elastic lower layer for easier track construction, to place an intermediate layer of elastomers thereon and to screw the rail thereon using the conventional tension clamp, sleeper screw and washers.
- the screw is fastened in the concrete slab using a standard dowel.
- the following structure can be used for the more heavily loaded area: a ribbed plate is placed on an elastomer plate and, if necessary, a beveled plastic compensating plate, which in turn is screwed to the concrete body using a sleeper screw, spring washer and plastic dowel.
- the rail is placed on the ribbed plate and screwed to the ribbed plate with the usual tension clamp, hook screw, nut and washer.
- Figure 1 shows in cross section and in plan view an attachment according to the invention for lower loads.
- Figure 2 shows in cross section and in plan view an attachment for heavy loads.
- FIG. 3 shows these types of fastening on a concrete sleeper.
- FIG. 4 shows these types of fastening on a concrete support plate and
- FIG. 5 shows the fastening on longitudinal concrete beams.
- Figure 6 shows in cross section a fastening system according to the prior art with a specially shaped bead of the concrete body and specially designed angle guide plates.
- Figure 7 shows an attachment according to the prior art with a complex dowel system.
- FIG. 8 shows a sleeper screw with a thread in the area of the concrete body and a threaded part with a nut instead of a screw head.
- FIGS. 9 to 11 show a special screw connection with a sleeper screw, which enables shock-absorbing spring-back, as a side view, as an oblique side view and in the installed state.
- the space between the longitudinal concrete beams can be filled with soil, substrate or the like and even greened according to the invention.
- reinforced concrete slabs must continue to do so care must be taken to ensure that the space has surface drainage in a suitable manner, which must not result in moisture penetration of the subsurface by dust, dirt, snow or ice, and does not impair the bedding resistance.
- the upstand that is used according to the invention is most easily already produced during the manufacture of the concrete parts. As already mentioned, they could be milled, ground or cut if necessary. In principle, it is of course also possible to cut a notch in an initially smooth concrete body, which has a practically vertical upward edging, at least on the outside. If there is an upstand on the inside, this is not harmful, but this second upstand on the inside has no influence on the function and stability of the laid track. Furthermore, such a construction leads to an unnecessary consumption of material at a point where this material no longer fulfills a function and makes drainage and self-cleaning of the support plate more difficult.
- a certain level compensation can take place by means of different thickness compensation plates.
- the track is preferably laid so that the rails remain parallel to the ground. Elevations in curves are practically done exclusively by appropriate Inclination of the concrete body in relation to the surface. However, it is entirely possible to compensate for the height of the insulation board between 1 and 10 mm and the intermediate layer between approx. 4 and 50 mm and to correct the rail position.
- a major advantage of the method according to the invention is that the rail can be fastened to a ribbed plate using standard elements such as ribbed plates, sleeper screws, spring washers, hook screws with nuts and washers, tension clamps and plastic dowels. This also simplifies the logistics when laying and repairing rails laid according to the invention.
- the screw connection can also be carried out using sleeper screws which have an asymmetrical thread. These ensure a firmer fit in plastic dowels.
- the screwing is then preferably carried out using sleeper screws, which not only have an asymmetrical thread, but also a machine thread, for example a metric or inch thread part, instead of a screw head in the upper part. have a mother. This part of the machine thread enables a height adjustment of the ribbed plate without having to loosen the collar tie screw from the concrete body.
- Figure 8 shows such a screw.
- a shock-absorbing spring-back with a special threshold screw.
- It is a sleeper screw with a sleeper screw thread at the lower end, a middle part that is cylindrical or oval and has no thread, an upper part that is cylindrical and has a machine thread, an upper tip that acts as a hexagon head or hexagon imbus is configured, an optionally eccentrically designed plastic collar bushing fitting around the central cylindrical or oval part of the screw, a spiral spring fitting around the cylindrical part of the screw and a lockable stop nut fitting on the machine thread.
- the sleeper screw thread preferably corresponds to the standard of European railways, but differently dimensioned sleeper screw threads can also be used.
- the metric thread shown as an example also preferably corresponds to the standard of the European railways, however other machine threads such as metric threads or inch threads can also be used here.
- the plastic collar bushing can also be oval or with an eccentric bore, so that either an undesired turning of the collar bushing in the borehole can be prevented, or a change in position of the rail support can be brought about by turning.
- the socket is made of a plastic that is able to insulate against track currents. While the inside diameter of the bushing corresponds to the diameter of the cylindrical part of the collar sleeper screw, the collar bushing fits on the outside into a correspondingly prepared borehole of the sleeper or the rail support.
- the upper tip of the sleeper screw is preferably designed as a hexagon head, but can also be configured as a hexagon headbus. Square heads or square imbus tips or other polygonal tips can in principle also be used, but are less suitable for practical use and the standard tools available there. Finally, it is possible to design a central part of the screw with a polygon instead of the polygon tip. Such collar sleeper screws can be tightened with an appropriate key.
- the spiral spring is preferably ground at right angles on its top and bottom, so that a full-surface support on the socket on the one hand and the stop nut on the other hand is ensured.
- the coil spring has the task of applying a defined contact pressure from the sleeper screw via the coil spring and bush to a rail support part to be fastened. The coil spring should never be on "block - left
- the spring is guided over the cylindrical part of the sleeper screw without damaging the machine thread in the upper part of the sleeper screw.
- the spiral spring is preferably made of spring steel such as 38 Si 7.
- the stop nut which has the task of ensuring a defined contact pressure on the coil spring and thus on the collar bushing, is designed in such a way that it cannot come loose by itself. This is preferably done by an inserted plastic ring in the upper part, which is smaller in diameter than the machine thread in the upper part of the sleeper screw. When the nut is screwed onto the sleeper screw, the plastic ring presses into the thread without damaging it. An automatic loosening of the stop nut is not possible even with dynamic loads.
- the stop nut can also be cranked in the upper area and thereby prevented from loosening independently.
- this configuration has the disadvantage that the threaded part on the sleeper screw is damaged or even destroyed, and reuse is therefore no longer possible.
- the sleeper screw is connected to the surface by screwing it into the polygonal head or polygonal bus Prefabricated borehole and / or a corresponding dowel made of plastic or similar suitable materials with synchronous thread or shaft diameters.
- This new sleeper screw is therefore universally applicable and can therefore easily replace the types of sleeper screws previously used.
- a disadvantage of all previously known fastenings of rails on concrete support plates or concrete longitudinal beams by screwing is that rail vibrations occur in particular in the high-speed range, which lead to an undesirable load on the screw connections of the rails to the concrete supporting plate or concrete longitudinal beams.
- These rail vibrations in the curve area are of particular importance, so that this limits the maximum speed of the trains in the curves.
- These rail vibrations can be greatly reduced, so that they are practically no longer of importance and no longer remain a limiting factor for the maximum permissible speed if the screw connection is carried out at uneven intervals.
- the rail of the outer side is screwed at shorter intervals than the inner side. It is particularly preferred to choose the distances chaotically irregular, since this leads to the strongest suppression of rail vibrations.
- This type of screwing is the subject of DE-197 06 442.6.
- the screw connection is preferably carried out according to the method according to the invention, in which at least one steel plate and at least one electrically insulating layer are laid between the rail foot and the concrete body, and the cornering forces of the rails and the steel plate connected to them are absorbed by a practically vertical, external upstand of the concrete body be, a plastic layer is installed between the steel plate and the lateral upstand.
- the screw connection is preferably carried out using sleeper screws which have an asymmetrical thread.
- sleeper screws which have an asymmetrical thread.
