Definitions
- the present invention relates to a method for establishing a positionally accurate connection on a travel path for a track-bound vehicle, in particular a magnetic levitation train, between a carrier and at least one essentially continuous attachment part attached to the carrier and running in the longitudinal direction of the carrier for guiding the vehicle , wherein the attachment has guide and / or drive elements. Furthermore, the invention relates to a corresponding route.
- Generic routes are usually designed as elevated railways, in which a carrier has functional parts for guiding the vehicle, in particular magnetic high-speed railways.
- the functional parts must be arranged on the carrier with extreme precision and with only slight deviations from one another.
- the beams are usually made of concrete or steel.
- the attachments arranged on the carrier with the functional elements are usually screwed together after precise machining of the contact surfaces.
- the console itself is cast or strained in the carrier. Finally, the attachment is screwed onto the console.
- EP 0 987 370 A1 discloses a guideway in which the bracket is screwed onto a concrete support or is concreted in according to another exemplary embodiment.
- the console in turn has head plates, which form the connection surface to an attachment.
- the attachment is screwed onto the head plates.
- a further generic travel path which has attachments with functional elements arranged on a carrier.
- the attachments have a web running along the carrier, on which functional elements such as sliding surfaces, side guide rails and stators are arranged.
- a cross member is welded to the web at a distance from one another at right angles to the web.
- the free end of the cross member in turn has a connecting plate which is also welded at right angles to the cross member.
- the attachment is screwed onto the carrier via holes in the connecting plate.
- components are also arranged discretely on the carrier, which are fastened to the carrier and to which in turn the attachment is fastened, welded on here.
- a disadvantage of this design is also the high manufacturing and assembly costs when attaching the attachment to the carrier.
- the object of the present invention is therefore to avoid the disadvantages mentioned and to create an inexpensive and easily producible route.
- the essentially continuous add-on part running in the longitudinal direction of the support is connected to the support directly by means of a rod which at least partially projects through the add-on part and is attached to the support on the other hand.
- the attachment is arranged directly on the carrier.
- the attachment is therefore not on consoles or cross beams attached. Rather, it is connected directly to the carrier.
- the rod is mounted on the one hand in the add-on part and on the other hand in the carrier.
- the rod is preferably a tie rod.
- a flaky reinforcing steel, screws or other steels can also be used.
- the tensioning advantageously takes place in the carrier and / or on the side of the carrier opposite the fastening point.
- the tie rod is either anchored in the carrier itself or runs through the carrier and is attached to the opposite side of the carrier.
- the attachment is then tightened, for example, by means of a nut which stretches the tie rod and thereby presses the attachment against the carrier.
- the carrier especially if it is made of concrete, does not experience any harmful tensile stresses. At the attachment point, the concrete is therefore essentially only exposed to compressive stresses which are particularly advantageous for concrete.
- At least one intermediate piece is arranged between the carrier and the attachment, through which the tension rod runs.
- the intermediate piece creates the required position and distance of the attachment in relation to the carrier or an opposite, parallel attachment.
- the adapter allows the attachment to be positioned very precisely.
- the required deviation of the guide and drive elements, which are arranged on the attachment, from the straight line of the carrier is brought about by means of the intermediate pieces, which have different dimensions. This creates a particularly inexpensive manufacturing process. It is particularly simple if the intermediate piece is concreted or made from a hardenable mass.
- the add-on part can either be concreted, for example on the top chord of the carrier, or subsequently, after alignment and fixing of the add-on part, or it can be made from the hardenable mass.
- the add-on part is aligned and fixed in position, then the intermediate piece between the add-on part and the carrier is concreted or manufactured with the aid of a suitable formwork, and finally the formwork is removed again.
- the intermediate piece and / or connecting surfaces of the add-on parts can be machined in order to ensure the exact position of the add-on part.
- the connecting surface between the carrier and the intermediate piece or, if an intermediate piece is not present, the connecting surface of the carrier can be machined accordingly before the attachment part is connected to the carrier.
- the intermediate piece is advantageously concreted or produced from a hardenable mass. This creates a particularly precise position of the interface to the attachment.
- the attachment essentially consists of a base body, on which the side guide rails, slide strips and / or stator brackets are subsequently arranged. A fine Direction of these functional elements can be done in relation to the attachment.
- the add-on part is connected to the carrier by means of at least one rod running in the transverse direction of the carrier, in particular a tensioning rod.
- the rod projects on the one hand through a continuous component of the add-on part that runs in the longitudinal direction of the carrier, and on the other hand is fastened to the carrier.
- the rod is preferably a tie rod.
- a flaky reinforcing steel, screws or other steels can also be used.
- the component running in the longitudinal direction of the add-on part is advantageously a web with guide and / or drive elements also arranged thereon and running in the longitudinal direction of the add-on part.
- the tensioning rod clamps the attachment against the carrier, whereby an exact position of the attachment is obtained.
- the use of a large number of screw connections or additional welded connections can essentially be avoided.
- the attachment connects the attachment directly to the carrier. No component is required which is fastened to the carrier and on which the add-on part is in turn arranged.
- a connecting part, which arranges the attachment on the carrier, is fastened on the one hand in the attachment and on the other hand on the carrier. If the add-on part with the rods is arranged on the carrier independently of the opposite add-on parts, then a simple independent exchange of the add-on parts is possible.
- the tendon is advantageously a tendon without a bond.
- a particularly simple and high tension is applied, as a result of which the attachment is reliably and permanently attached to the carrier. It is also possible to simply replace the attachment to carry out maintenance or repair work if necessary.
- a tension rod made of fiber-reinforced plastic has proven to be particularly advantageous because it can exert high forces and, on the other hand, is not subject to corrosion.
- the end of the tie rod is a thread or a head on which the add-on part rests.
- a tensioning device which provides the tensioning rod with sufficient tension, is arranged in the center of the support, on the intermediate piece or on the attachment itself.
- tie rod is divided so that it can be fastened, screwed and / or pretensioned from the inside of the beam, a particularly simple design is created, since two attachments can be attached simultaneously using a single clamping device.
- tensioning rod has protective caps to secure the position during concreting and / or to protect against mechanical damage or corrosion, advantageous processing is possible without any further protective measures.
- the add-on part in particular the side guide element, has openings for screwing the add-on part and / or for prestressing the tensioning rod. This significantly increases the accessibility to the tie rod, which simplifies and speeds up assembly.
- an intermediate piece is arranged between the carrier and the attachment, the positioning of the attachment with respect to the carrier is simplified.
- the intermediate piece is to be designed so that there is no power transmission between the tie rod and the intermediate piece.
- the attachment does not affect the attachment of the attachment directly to the carrier.
- the intermediate piece can be made continuously along the carrier and the attachment. However, it is preferably arranged at least in the area of the tension rods. On the one hand, the intermediate piece creates a certain distance between the attachment and the carrier. On the other hand, it serves as the contact surface of the attachment, so that the attachment can be positioned exactly by the intermediate piece.
- the intermediate piece or the connection surface on the carrier is additionally connected to the attachment in a form-fitting manner, a particularly good absorption of transverse forces is made possible. Compliance with the exact location of the This means that the component can also be retained even under unfavorable influences.
- the intermediate piece is advantageously concreted onto the upper chord of the carrier. A displacement of the intermediate piece on the carrier can thus be ruled out and the position of the attachment can be maintained in a particularly advantageous manner.
- the intermediate piece is made of metallic, non-metallic-organic material and / or organic material and / or composite materials, in particular high-strength concrete or fiber concrete, the compressive force exerted on the intermediate piece is absorbed particularly well without the position of the add-on part changing.
- the intermediate piece has head bolts and / or anchor rods for fastening in the support, or if the intermediate piece is held by a connecting reinforcement which protrudes from the support, a particularly advantageous connection of the intermediate piece to the support is created, which position even under high external forces can't change.
- the intermediate piece has a reinforcement, in particular a spiral reinforcement, which preferably absorbs the tensile forces from the prestressing reinforcement of the prestressing rod. This prevents the intermediate piece from being destroyed by a high clamping force.
- a redundant fastening system is provided, by means of which the attachment part can be adjusted.
- the redundant fastening system also enables an error in the fastening, for example a decrease in the pretensioning force, to be visually visible and, on the other hand, to reliably prevent the attachment from being able to be completely detached from the carrier. If that If the redundant fastening system is designed to be open to faults, faults in the fastening can be optically recognized very quickly and then rectified.
- a watercourse is provided on the intermediate piece with a water drainage for drainage, which drainage is arranged essentially vertically.
- a water drainage for drainage which drainage is arranged essentially vertically.
- rain or melt water can be drained away from the carrier in a targeted manner without the attachment and thus the functional elements for guiding the vehicle being impaired by the water.
- the water drain is arranged such that the water is directed past the functional parts of the attachment.
- a particularly light version of the intermediate piece is obtained in that it has at least one, preferably two webs, which rest at one end on the carrier and, with their second end, has a system for the attachment that is arranged essentially perpendicular to the extension of the webs ,
- the intermediate piece can be block-shaped, L-shaped, T-shaped or U-shaped.
- the distance between two of the intermediate pieces in the longitudinal direction of the travel path is essentially an integral part of the length of the add-on part. This uniform arrangement of the intermediate pieces causes a uniform loading of the attachment and its fastening elements.
- the attachments which are usually shorter than the carrier, are fastened to the carrier in abutting fashion. At the joint of two attachments sometimes a single, possibly longer intermediate piece is arranged. This longer adapter bridges the two successive attachments.
- FIG. 1 shows a cross section of a carrier with directly attached parts
- Figure 2 is a perspective view of Figure 1 without carrier
- Figure 3 is a detailed view of a strained attachment.
- Figure 1 shows a section through a guideway girder 1, which has webs 2 and 3 and an upper flange 4.
- the carrier 1 can also have a lower flange, not shown, in order to increase the stability of the carrier 1.
- the carrier 1 shown here is made of concrete. In another embodiment, not shown, the carrier 1 could, however, also be made of other materials, for example as a steel structure.
- Add-on parts 5 are arranged at the spaced ends of the upper chord 4.
- the add-on parts 5 are modules with specific lengths.
- the individual modules are lined up in the longitudinal direction of the carrier 1 and connected to the upper goods 4.
- Various functional elements for driving a vehicle are arranged on the attachments 5. These functional elements must have a very exact position in order to be able to operate a magnetic levitation train vehicle without problems, for example.
- the functional elements of the attachment 5 are a slide bar 6, one Lateral guide rail 7 and a stator holder 8 with a stator 9 attached to it.
- the attachment 5 consists of a compact module which is screwed onto the support 1 at the construction site, for example. An exact pre-machining of the contact points between the attachment 5 and the carrier 1 ensures an exact alignment of the attachment 5 with the functional elements.
- the attachment 5 has a continuous web 10 running along the carrier 1.
- the web 10 represents a connection between the slide bar 6 and the stator holder 8. Together with the side guide rail 7, this results in a box-like design, which in itself is very stable.
- the add-on part 5 is connected to the carrier 1, in particular its upper flange 4, on the web 10.
- a tie rod 11 is provided.
- the tensioning rod 11 tensions the attachment 5 with the interposition of an intermediate piece 12 against the upper chord 4 of the carrier 1.
- the tensioning rod 11 has at one end a thread with a nut 15 which is assigned to the attachment 5.
- the other end of the tension rod 11 is connected to a tensioning device 16.
- the clamping device 16 is located in an assembly opening 20 of the carrier 1 and is arranged essentially in the center of the carrier 1.
- the tensioning device 16 is connected to a further tensioning rod 11 '.
- the tensioning device 16 can thus be used to tension the guide system for the magnetic levitation train, that is to say both of the attachment parts 5 and 5 ′ lying opposite one another, to the carrier 1.
- the tensioning rod 16, the tension rod 11 or 11 ' which consists for example of steel or fiber-reinforced plastic, is tensioned in such a way that the attachments 5, 5' are pressed firmly onto the carrier 1 or the intermediate piece 12.
- the prestressing and the arrangement of the tensioning rod 11 on the web 10, which essentially runs through the entire attachment 5 in the longitudinal direction of the attachment 5 and thus advantageously represents a load-bearing component for the attachment 5, ensures secure attachment of the attachment 5 in the correct position guaranteed on the carrier even when crossing with a magnetic levitation railway vehicle.
- a pressure plate 17 is provided in the present exemplary embodiment, which transmits the force from the tension rod 11 into the attachment 5.
- the carrier 1 is made of concrete and the intermediate piece 12 made of metal.
- the intermediate piece 12 has head bolts 13 which protrude into the upper flange 4 of the carrier 1 and are concreted in there.
- the head bolts 13 establish a firm connection between the intermediate piece 12 and the carrier 1. This ensures an exact position of the attachment 5 on the carrier 1.
- the intermediate piece 12 becomes part of the carrier 1 through the connection to the carrier 1 via the head bolts 13.
- the attachment part 5 could also be clamped directly to the upper flange 4 of the carrier Carrier 1 take place.
- the intermediate piece 12 if it is made of metal, on the other hand, is somewhat more advantageously suitable for machining the contact surface with the web 10 in order to create a defined contact surface here, for example by exciting machining or by welding material.
- the intermediate piece is made of concrete, it can be advantageous be when a connection between the intermediate piece and the beam is created by a reinforcement.
- FIG. 2 shows a perspective illustration of the exemplary embodiment from FIG. 1, the carrier 1 itself not being drawn for reasons of clarity. It can be seen from the illustration in FIG. 2 that a plurality of tensioning rods 11, 11 'are arranged along the attachments 5, 5' for fastening the attachments 5, 5 '. Two opposite fastening points of the attachments 5, 5 'are each provided with a tensioning device 16 and two tensioning rods 11, 11'. The two tension rods 11 and 11 'are tensioned by means of a single tensioning device 16. The attachments 5 and 5 'are pressed against the carrier 1 via the intermediate pieces 12.
- the attachments 5, 5 ' have a shorter length than the carrier 1.
- the intermediate pieces 12 'are each provided with two openings so that the tension rod of the first attachment part can be passed through the first opening and the tension rod of the second attachment part can be passed through the second opening.
- the intermediate pieces 12 are continuous. This means that individual parts of the intermediate pieces 12, 12 'are not arranged on the carrier 1, but rather that a single component running along the carrier the intermediate piece 12 forms.
- an intermediate piece 12, 12 ' can also be dispensed with entirely and the add-on part 5, 5' can be clamped directly to the carrier 1.
- Figure 3 shows an enlarged section of a fastening of the attachment 5 on the carrier 1.
- the intermediate piece 12 used in this embodiment is made of concrete. It can either be installed as an independent component or cast onto the carrier 1. For this purpose, a connecting reinforcement for the fixed connection of the intermediate piece 12 and the beam 1 is advantageous.
- the intermediate piece 12 can be cast in between the add-on part 5 and the carrier 1.
- an auxiliary device is used, with which the attachment 5 is held and fixed in a predetermined, defined position relative to the carrier. Then the area of the later intermediate piece is provided with formwork and the concrete is poured in. After the concrete has hardened, the formwork and the auxiliary device can be removed again. The attachment 5 then maintains the previously set position even after the attachment 5 has been tightened. A processing of the connection points between the web 10 and the intermediate piece 12 or the end face of the upper flange 4 is therefore not necessary.
- the tendon 11 is a tendon without a bond with the concrete, which makes subsequent tensioning possible.
- an assembly opening 21 is arranged in the side guide rail 7. Through the mounting opening 21, the nut 15 of the tie rod 11 can be screwed and thus the tie rod 11 can be tensioned.
- the redundant fastening system consists of two bolts 23 which are fastened in the intermediate piece 12.
- the web 10 of the add-on part 5 has an enlarged bore 24 in relation to the bolts 23. If the attachment via the tension rod 11 and the nut 15 fails, the add-on part 5 sags onto the bolts 23 and is then temporarily kept there. During an inspection it should be noted that the bore 24 is in contact with the bolt 23 on its upper side. The attachment 5 can then be repaired or readjusted.
- a reinforcing plate 22 is provided, which is welded at right angles to the longitudinal axis of the attachment 5 between the web 10, the slide bar 6, the side guide rail 7 and the stator bracket 8.
- the add-on part 5 becomes a stable, independent module, which can be clamped to the carrier 1 with a precise shape.
- other, stable designs of the attachment 5 are also possible.
- the intermediate piece 12 is formed continuously along the upper flange 4, it is advantageous if water drains 25 are arranged in the intermediate piece 12. As a result, rain and melt water is largely drained from the attachment 5, whereby the functionality of the guide elements for the vehicle is not impaired. It is particularly advantageous if the water drain 25 is designed such that the water draining largely away from the functional elements of the attachment 5, e.g. is directed towards the carrier 1.
- the present invention is not limited to the embodiments shown. Combinations with one another and other designs which are within the scope of the patent claims are also possible.
- the design and the material of the intermediate piece 12 can be different than in the exemplary embodiments shown.
- the tailpiece 12 can also be dispensed with entirely, without having to forego the secure attachment of the attachment with the type according to the invention.
- the particular advantage of the invention is that fasteners are saved and thus the manufacture and assembly can be done faster and cheaper.
