Description

Die Erfindung bezieht sich auf einen Fahrweg für Landverkehrswege, vorzugsweise für Magnetschwebebahnen, z. B. TRANSRAPID, mit auf in Ortbeton- oder Fertigteilbauweise gefertigten Unterbauten angeordneten Fertigteil-Fahrwegträgern, die wenigstens einen hohlen bewehrten Spannbeton-Längsträger aufweisen, und mit quer zur Fahrbahn durchgehenden, den Spannbeton-Längsträger beidseits überkragenden, als getrennte Bauteile gefertigten Fahrwegplatten.The invention relates to a driveway for land transport routes, preferably for magnetic levitation trains, e.g. B. TRANSRAPID, with on-site concrete or precast construction manufactured substructures arranged prefabricated guideway girders, which have at least one hollow reinforced prestressed concrete longitudinal member, and with the prestressed concrete side member running across the carriageway on both sides cantilevered guideway slabs manufactured as separate components.

Ein solcher Fahrweg ist aus der DE 298 09 580 U1 bekannt, wobei dort die Fahrweg-Längsträger aus Stahl bestehen.Such a guideway is known from DE 298 09 580 U1, the guideway side members there are made of steel.

Ähnlich wie die ebenfalls vorgeschlagenen, jedoch wegen der Korrosionsanfälligkeit und der erhöhten Schallemission und der dadurch resultierenden Belastung der Umwelt nachteiligen Stahlkonstruktion sind die bisherigen Beton-Fertigteil-Fahrwegträger - man vgl. hierzu beispielsweise die DE 41 15 936 A1 - grundsätzlich so aufgebaut, dass ein hohler bewehrter Spannbeton-Längsträger mit trapezförmigem Querschnitt vorgesehen ist, dessen oben liegender größerer Basisschenkel links und rechts verlängert ist. Üblicherweise ist die Verlängerung bis auf die Gesamtbreite des Fahrwegs ausgelegt, so dass lediglich noch die fahrwegseitigen Komponenten des Trag- und Führungssystems des Fahrweges (Seitenführungsschienen, Gleitleisten und Statorpakete) angebracht werden müssen.Similar to those also proposed, but because of the susceptibility to corrosion and the increased noise emission and the resulting load The previous precast concrete guideway girders are environmentally harmful steel structures - cf. for this, for example, DE 41 15 936 A1 - in principle constructed in such a way that a hollow reinforced prestressed longitudinal member with a trapezoidal shape Cross section is provided, the larger base leg located above left and right is extended. The extension is usually up to the total width of the route is designed so that only the route side Components of the supporting and guiding system of the guideway (side guide rails, Slide rails and stator packs) must be attached.

Ein solcher Spannbeton-Längsträger lässt sich einigermaßen wirtschaftlich lediglich als gerütteltes Betonformteil herstellen, das eine besondere an den Enden aufgefächerte Bewehrung erforderlich macht. Dies wiederum erfordert einen praktisch vollen Querschnitt im Endbereich zur Unterbringung der Bewehrungseisen und auch in den Hohl- und Mittelbereichen sind immer noch Wanddicken von mindestens 30 bis 40 cm erforderlich, um in gerüttelter Betonbauweise die notwendige Festigkeit zu gewährleisten. Diese Schwierigkeiten gelten prinzipiell auch bei einer Hybridkonstruktion, bei der seitlichen Arme der Spannbeton-Längsträger nicht auf die volle Fahrwegbreite ausgelegt sind, sondern etwas verkürzt sind. An die verkürzten Arme sind in aufwendiger Weise maßhaltige Stahlelemente angeschraubt, die ihrerseits wiederum die fahrwegseitigen Komponenten des Trag- und Führungssystems bilden bzw. haltern. Auch hier muss der Spannbeton-Längsträger mit den verkürzten Armen durch Rütteln in einer Form hergestellt werden, was wiederum die vorstehend beschriebenen Schwierigkeiten mit dem erhöhten Gewicht mit sich bringt, das nicht nur im Hinblick auf den erhöhten Materialaufwand, sondern insbesondere auch wegen der schwierigen Handhabbarkeit der Fertigteile beim Einbau an der Baustelle unerwünscht ist.Such a prestressed concrete longitudinal beam can only be reasonably economical produce as a shaken concrete part that has a special one at the ends fanned reinforcement is required. This in turn requires a practical one full cross section in the end area to accommodate the reinforcement bars and even in the hollow and middle areas there are still wall thicknesses of at least 30 to 40 cm required to achieve the necessary in shaken concrete construction To ensure strength. In principle, these difficulties also apply with a hybrid construction, with the lateral arms of the prestressed concrete side members are not designed for the full width of the route, but are somewhat shortened. On the shortened arms are screwed onto dimensionally stable steel elements, which in turn are the trackside components of the support and Form or maintain a management system. Here too, the prestressed concrete side member must be used with the shortened arms made by shaking in a mold be, which in turn the difficulties described above with the brings with it increased weight, not only in view of the increased material expenditure, but especially because of the difficult handling the finished parts are undesirable when installed on site.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Fahrweg für Magnetschwebebahnen der eingangs genannten Art so auszugestalten, dass die Spannbeton-Längsträger einfacher, kostengünstiger und mit geringeren Wandstärken und damit geringeren Gewichten hergestellt werden können.The invention is therefore based on the object of a guideway for magnetic levitation trains of the type mentioned in such a way that the prestressed concrete longitudinal beams easier, cheaper and with smaller wall thicknesses and thus lower weights can be manufactured.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass der oder die Spannbeton-Längsträger als im Wege der Schleuderbetonfertigung hergestellte Spannbetontragrohre mit flachen oberen Auflageschultern für die Fahrwegplatten ausgebildet sind.To achieve this object, the invention provides that the one or more Prestressed concrete longitudinal beams as manufactured by means of centrifugal concrete production Prestressed concrete support pipes with flat upper support shoulders for the guideway slabs are trained.

Durch die Auftrennung von Trägerelement und Fahrwegsplatte, wobei die Fahrwegplatten sowohl bewehrte Betonplatten, als auch Stahlblechkonstruktionen sein können, d. h. durch den Verzicht darauf an den Spannbeton-Längsträger seitlich die Auflageschenkel für den Fahrweg mit anzubetonieren, lässt sich der Spannbeton-Längsträger als im wesentlichen rohrförmiges symmetrisches Schleuderbetonbauteil fertigen. Diese Schleuderbetonfertigung ermöglicht nicht nur geringere Wandstärken und damit geringere Gewichte, sondern man erhält auf diese Art und Weise ein durchgehend hohles Trägerbauteil, das im Inneren einen großen durchgehenden Raum zur Verlegung von Kabeln und Versorgungsleitungen bietet. Die Auflageschultern sollen dabei unter anderem durch seitlich über die im wesentlichen zylindrische Rohrform überstehende Verstärkungsrippen gebildet sein, wobei diese Verstärkungsrippen mit den um eine Größenordnung stärker auskragenden Flanschen der bisherigen Fahrwegträgern nicht zu vergleichen sind. Durch diese überstehenden Rippen zur Erzielung einer etwas größeren Auflagefläche wird die Unwucht des Trägers - die im übrigen bei der Fertigung durch andere Maßnahmen noch weiter ausgeglichen werden kann, worauf aber weiter unten noch eingegangen werden soll - klein genug gehalten, so dass eine einfache Schleuderbetonfertigung möglich ist.By separating the support element and guideway slab, the guideway slabs be both reinforced concrete slabs and sheet steel constructions can, d. H. by not using the prestressed concrete side member on the side the prestressed concrete side member can be concreted with the support legs for the track as a substantially tubular symmetrical spun concrete component manufacture. This centrifugal concrete production not only enables less Wall thicknesses and thus lower weights, but you get this way and way a continuously hollow support member that has a large inside provides continuous space for laying cables and supply lines. The support shoulders should, among other things, laterally over the in essentially cylindrical tubular shape projecting reinforcing ribs be, these reinforcing ribs with the order of magnitude stronger cantilevered flanges of the previous guideway girders cannot be compared are. Through these protruding ribs to achieve a slightly larger one The support surface becomes the unbalance of the wearer - which, incidentally, during manufacture can be compensated for by other measures, but what to be discussed further below - kept small enough so that one simple centrifugal concrete production is possible.

Im Gegensatz zu den bei den üblichen bisherigen Konstruktionen etwa 20 m - 31 m langen Fertigteil-Fahrwegträgern und den natürlich entsprechend lange auszubildenden Spannbetontragrohren in Schleuderbetonbauweise sollen in Weiterbildung der Erfindung die Fahrwegplatten aus einer Mehrzahl von kurzen beabstandeten Fahrwegplatten-Segmenten von vorzugsweise ca. 6 m Länge bestehen. Diese Plattensegmente sind wesentlich schneller austauschbar und in Wartungs- oder Reparaturfällen einzeln von den Typenträgern demontierbar und somit auch reparaturfreundlich, insbesondere bei der bevorzugten Fertigung als Stahlblechkonstruktion, in Maschinen leicht zu fräsen und damit exakt zu bearbeiten, im Gegensatz zu den vorhandenen direkt anbetonierten Fahrwegplatten. Die Plattensegmente zur Bildung einer Fahrwegplatte können durch Verschraubungen, ähnlich wie bei vorhandenen Schwellensystemen einfach und dauerhaft an den Spannbetontragrohren befestigt werden. Als weiterer Vorteil ist herauszuheben, daß die Segmente exakt montierbar sind.In contrast to the 20 m - 31 in the usual previous constructions m long prefabricated guideway girders and of course the correspondingly long apprentices Prestressed concrete support pipes in centrifugal concrete construction should be in further training of the invention, the guideway panels are made of a plurality of short spaced Track slab segments are preferably approximately 6 m in length. These plate segments can be exchanged much faster and in maintenance or Repairs can be dismantled individually from the type holder and thus also easy to repair, especially in the preferred production as a sheet steel construction, In contrast, it is easy to mill in machines and can therefore be machined precisely to the existing concrete slabs. The plate segments To form a guideway slab, screw connections, similar as with existing threshold systems, simply and permanently on the Prestressed concrete support pipes are attached. Another advantage is that that the segments can be assembled exactly.

Die Aufteilung der Fahrwegplatte eines Fertigteil-Fahrwegträgers von etwa 20 m - 31 m Länge in eine Mehrzahl von Plattensegmenten hat nicht nur den Vorteil einer einfacheren und auch genaueren Bearbeitbarkeit dieser Plattensegmente und einer einfacheren Handhabbarkeit. Neben dem nochmals erheblich verringerten Gewicht des notwendig als einteiliges Bauteil an der Baustelle zu handhabenden Spannbetontragrohrs braucht bei dessen Verlegung die Fahrwegplatte noch nicht angeschraubt sein, so dass das Gewicht - unabhängig von der bereits erheblichen Gewichtseinsparung durch die Schleuderbetonfertigung - nochmals reduziert ist. The division of the guideway slab of a prefabricated guideway girder of about 20 m - 31 m length in a plurality of plate segments not only has the advantage of one easier and also more precise machinability of these plate segments and easier handling. In addition to the significantly reduced Weight of the one-piece component to be handled at the construction site The guideway slab does not yet need prestressed concrete support pipe when laying it be screwed on so that the weight - regardless of the already considerable Weight saving through the centrifugal concrete production - is reduced again.

Darüber hinaus bietet die Aufteilung der Fahrwegplatte in einzelne Plattensegmente den Vorteil, dass eine einfachere Querneigung des Fahrwegs in Kurven erzielt werden kann und insbesondere die Übergangsbereiche zwischen den verschiedenen Neigungsabschnitten einfacher gestaltet werden.In addition, the division of the guideway slab into individual slab segments offers the advantage that an easier cross slope of the road in curves can be achieved and in particular the transition areas between the different Slope sections can be made easier.

Ein großes Problem bei derartigen Fertigteil-Fahrwegträgern bilden die hohen Temperaturunterschiede bei den bisherigen monolithischen Strukturen. Oben wird die Fahrwegplatte durch die Sonnenaufstrahlung heiß, während der darunter liegende Spannbeton-Längsträger im Schatten liegt und deshalb kühl bleibt. Es er-geben sich dadurch sehr hohe Beanspruchungen, die sich durch die angeschraubten - vorteilhafterweise noch in einzelne Plattensegmente unterteilten - Fahrwegplatten sehr viel besser abfangen lassen. Gegenüber einem ebenfalls vom Gewicht her leichten Stahlfahrweg, bei dem auch der Längsträger als Stahlträger ausgebildet ist, ist das Schallresonanzverhalten der erfindungsgemäßen Konstruktion wesentlich besser und man braucht vor allem auch keinen Korrosionsschutz.A big problem with such precast track girders are the high ones Temperature differences in the previous monolithic structures. Above the driveway slab is hot from the sun's rays, while the one below it Prestressed concrete side members lie in the shade and therefore remain cool. There is very high loads resulting from the screwed on - advantageously divided into individual plate segments - Have the guideway plates intercepted much better. Towards one too light weight steel guideway, in which the longitudinal beam as steel beam is formed, the sound resonance behavior of the invention Construction much better and above all you don't need any corrosion protection.

Bei einer aufgeständerten Fahrwegführung, bei der üblicherweise sogenannte A-Stützen Verwendung finden, soll das mittig zur Fahrwegplatte angeordnete Spannbetontragrohr mit nachträglich anbetonierten Stützkonsolen zur Lagerung auf den Stützpfeilern versehen sein. Zu diesem Zweck können in die Spannbetontragrohre Gewindebuchsen zum Einschrauben von in eine Stützkonsole einragenden Verankerungsstäben eingebettet sein und darüber hinaus können die Spannbetontragrohre im Auflagebereich der Stützkonsole zusätzlich eine aufgerauhte Oberfläche aufweisen, so dass auch hierdurch eine bessere Verbindung zwischen Spannbetontragrohr und Stützkonsole gewährleistet ist.In the case of a raised guideway, in which usually so-called A-pillars are used To be used is that which is arranged in the center of the track slab Prestressed concrete support pipe with retrofitted concrete brackets for storage be provided on the pillars. For this purpose you can use the prestressed concrete support pipes Threaded bushings for screwing in protruding into a support bracket Anchor rods can be embedded and in addition, the Prestressed concrete support pipes in the support console's support area also have a roughened Have surface, so that this also results in a better connection between the prestressed concrete support pipe and the support bracket is guaranteed.

Zur seitlichen Überhöhung des Fahrwegs in Kurvenabschnitten können Zwischenkeile zwischen die Auflageschultern der Spannbetontragrohre und die Fahrwegplatten eingebracht sein, oder - insbesondere bei sehr starken Überhöhungen in Kurvenabschnitten - die Spannbetontragrohre verdreht an den Stützkonsolen anbetoniert sein.Intermediate wedges can be used to elevate the travel path laterally in curve sections between the support shoulders of the prestressed concrete support pipes and the track slabs be introduced, or - especially in the case of very strong cant Curve sections - the prestressed concrete support pipes twisted onto the support brackets his.

Die erfindungsgemäße Ausgestaltung eines Fahrwegs mit im Wege der Schleuderbetonfertigung hergestellten Spannbetontragrohren lässt sich auch bei einem Fahrweg mit ebenerdiger Fahrwegführung hervorragend einsetzen. Hierzu wird bislang entweder eine durchgehende Mittelstützwand, oder eine Vielzahl von quer zur Fahrbahn gestellten niedrigen relativ eng beabstandeten (Abstand 3 bis 5 m) Querstützwänden vorgesehen - ein Überstand von ca. 80 bis 100 cm über dem Boden ist ja wegen des Übergreifens der Transrapid-Wagenkonstruktion um die Seitenwände des Fahrwegs auch bei der sogenannten ebenerdigen Fahrwegführung erforderlich, auf denen die Fertigteil-Fahrwegträger aufsitzen. Neben dem erhöhten Aufwand durch die in kurzen Abständen aufeinander anzuordnenden und wegen der hohen Gewichte tief im Boden zu verankernden Querstützen ergibt sich dadurch eine sehr hohe störende Schallbelastung durch einen lauten Ratterton infolge der ständigen Luftturbulenzen u. a. an den Querstützwänden, hervorgerufen durch hohe Fahrgeschwindikeiten.The inventive design of a driveway with the way of spun concrete production manufactured prestressed concrete support pipes can also be Excellent use of track with ground-level routing. To do this So far, either a continuous central support wall or a large number of crossways low, relatively closely spaced from the road (distance 3 to 5 m) Cross support walls provided - a protrusion of about 80 to 100 cm above the Soil is because of the overlap of the Transrapid carriage construction around Sidewalls of the driveway also with the so-called ground-level guideway required on which the precast track beams are seated. Next to the increased effort due to the need to be arranged at short intervals and because of the high weights results in cross supports to be anchored deep in the ground a very high disturbing noise level due to a loud Ratterton due to the constant air turbulence u. a. on the transverse support walls, caused by high driving speeds.

Um dies zu vermeiden ist erfindungsgemäß bei ebenerdiger Fahrwegsführung vorgesehen, dass zwei parallel in Abstand im Auflagerbereich miteinander verbundene Spannbetontragrohre, die gemeinsam die als getrenntes Bauteil gefertigte Fahrwegplatte, vorzugsweise in Form einzelner Plattensegmente, tragen, direkt auf den Bodenfundamenten abgestützt sind. Hierzu sollen die Spannbetontragrohre neben den oberen Auflageschultern mit seitlichen Abflachungen versehen sein, so dass sie bei einer Höhe von ca. 80 cm trotz der Nebeneinanderordnung in Abstand nur eine Gesamtbreite aufweisen, die deutlich unter der Breite des Fahrwegs zurückbleibt. Neben den vorstehend bereits angesprochenen Vorteilen hinsichtlich der Schall-entwicklung hat die erfindungsgemäße Konstruktion aus geschleuderten, vorgespannten, miteinander verbundenen Rechteckrohren mit einer Höhe von 60 bis 80 cm, die direkt auf den Bodenfundamenten abgestützt sind, den Vorteil, dass man sehr viel weniger Fundamente pro Streckeneinheit braucht. Während man bisher drei Fundamente je Fahrwegplatte von 6,20 m vorsehen musste, genügen bei der erfindungsgemäßen Konstruktion zwei endseitig angeordnete Fundamente auf die Gesamtlänge der Spannbetontragrohre von 20 m - 31 m. Dies bedeutet eine erhebliche Vereinfachung bei der Erstellung des Fahrwegs.In order to avoid this, according to the invention, the guideway is at ground level provided that two connected to each other in parallel at a distance in the support area Prestressed concrete support pipes, which together made the one as a separate component Wear guideway slab, preferably in the form of individual slab segments, are supported directly on the ground foundations. For this purpose, the prestressed concrete support pipes provided with side flats next to the upper support shoulders be at a height of about 80 cm despite the juxtaposition at a distance only have an overall width that is clearly below the width of the route remains. In addition to the advantages already mentioned above the construction according to the invention has a sound development from hurled, pre-tensioned, interconnected rectangular tubes with a height of 60 to 80 cm, which is supported directly on the ground foundations are the advantage that you have a lot less foundations per stretch needs. While there were three foundations per 6.20 m track slab had to provide, two ends are sufficient in the construction according to the invention arranged foundations on the total length of the prestressed concrete support pipes from 20 m - 31 m. This means a significant simplification when creating the Driveway.

Darüber hinaus eignet sich der Freiraum zwischen den geschleuderten Rechteckrohren zur geschützten Aufnahme von Kabeln und Versorgungsleitungen. Die im wesentlichen als Rechteckrohre ausgebildeten Spannbetontragrohre können dabei mit besonderem Vorteil seitlich an einen als Rechteckprofil ausgebildeten, seinerseits mit dem Bodenfundamenten verschraubbaren Stahlrahmen im Auflagerbereich angeschraubt sein.The space between the flung rectangular tubes is also suitable for the protected reception of cables and supply lines. The in can be designed essentially as rectangular pipes with particular advantage on the side of a square profile, in turn steel frame screwable to the base foundations in the support area be screwed on.

Bei einer ebenerdigen Fahrwegführung mit den erfindungsgemäßen hochkantgestellten geschleuderten Spannbetonrechteckrohren können diese über einen Keil-Zwischenträger an den Bodenfundamenten abgestützt sein, so dass man nicht für jede Neigung spezielle Fahrwegträger braucht, die dann wiederum spezielle Schleuderformen erforderlich machen.In the case of a ground-level guideway with the edged ones according to the invention centrifuged prestressed concrete rectangular pipes can do this via an intermediate wedge carrier be supported on the ground foundations, so that you can not stand for each slope needs special guideway supports, which in turn require special ones Make centrifuge molds necessary.

Um den nachteiligen Effekt eines Sich-Durchbiegens der ja über große Abschnitte freitragend verlegten Fertigteil-Fahrwegträger zu vermeiden, kann zum einen vorgesehen sein, dass die Spannbetontragrohre mit einer leichten Wölbung nach oben gefertigt werden, derart, dass sie in aufgelagerten Zustand aufgrund des Eigengewichts und des Gewichts der darauf lagernden Fahrwegplatte eine genau horizontale ebene Position einnehmen. Zum anderen kann die Wölbung nach oben so bemessen werden, daß die horizontale Position auch unter Verkehrlast erzielt wird.The disadvantageous effect of bending over large sections To avoid cantilevered prefabricated guideway girders can be provided on the one hand be that the prestressed concrete support pipes with a slight curvature after are manufactured in such a way that they are in the stored state due to the Own weight and the weight of the guideway slab on it exactly Take up a horizontal, flat position. On the other hand, the curvature can go up be dimensioned so that the horizontal position even under traffic load is achieved.

Darüber hinaus kann zum Auffangen des hohen Zuggewichts im unteren Abschnitt der Spannbetontragrohre in diesen Bereichen eine verstärkte Bewehrung aus dickeren und/oder dichter gepackten Spannstählen vorhanden sein. It can also be used to catch the high draw weight in the lower section the reinforced concrete support pipes in these areas reinforced reinforcement from thicker and / or densely packed prestressing steels.

Zur Herstellung der erfindungsgemäßen Spannbetontragrohre ist in Ausgestaltung der Erfindung eine Schleuderbetonform vorgesehen, bei der das die Außenform des Spannbetontragrohrs bestimmende Formblech mit asymmetrisch um die Rotationsachse verteilt angeordneten Stützrippen derart versehen ist, dass dadurch in Verbindung mit den unsymmetrisch verteilten Spannstählen die durch den erhöhten Betonanteil im Bereich der Auflageschultern gegebene Unwucht ausgeglichen wird. Dieser automatische Unwuchtausgleich - der natürlich nur deshalb möglich ist, weil die Fahrbahnplatten nicht wie bei bisherigen Betonfahrwegen direkt an den Fahrwegträgern angeformt sind, sondern als Einzelbauteile an den im Wege des Schleuderbetons hergestellten Spannbetontragrohren befestigt werden - lässt sich die Schleuderbetonfertigung sehr rationell und auch mit entsprechend hohen Rotationsgeschwindigkeiten und damit hoher Betondichte und dementsprechend geringerer Wandstärke realisieren.To manufacture the prestressed concrete support pipes according to the invention is in development the invention a centrifugal concrete mold is provided, in which the outer shape of the prestressed concrete support pipe with asymmetrical about the axis of rotation distributed support ribs is provided such that in connection with the asymmetrically distributed prestressing steel due to the increased The proportion of concrete in the area of the support shoulders compensates for any imbalance becomes. This automatic unbalance compensation - of course only because of that is possible because the pavement slabs are not directly as with previous concrete driveways are formed on the guideway girders, but as individual components on the in Pre-cast concrete support pipes made by centrifugal concrete are attached - The centrifugal concrete production can be done very efficiently and also with it high rotation speeds and thus high concrete density and accordingly Realize thinner walls.

Die in den Figuren 1 und 2 dargestellte Fahrwegkonstruktion für eine aufgeständerte Fahrwegführung - die mehrere Meter hohe Stütze 1 ist in Fig. 2 lediglich andeutungsweise dargestellt und in Fig. 1 völlig weggelassen worden - besteht im wesentlichen aus einem Spannbetontragrohr 2 und den als gesonderte Bauteile gefertigten Fahrwegplatten 3, wobei diese Fahrwegplatten nicht in gleicher Länge wie das Spannbetontragrohr 2 ausgebildet sind, sondern aus einzelnen Plattensegmenten mit entsprechend kürzerer Länge hergestellt werden. Dies ermöglicht, unabhängig von der Fertigung dieser Fahrwegplatten 3 als bewehrte Betonplatten oder, wie dargestellt, als Stahlblechkonstruktion, eine erheblich einfachere Bearbeitung der Fahrwegplatten. Insbesondere aber ermöglicht die völlige Trennung der Fahrwegplatten und des eigentlichen Längsträgers eine Ausbildung des Längsträgers als, zumindest angenähert symmetrische und damit nur geringe Unwucht zeigendes, Rohr, das demzufolge im Wege der Schleuderbetonfertigung hergestellt werden kann. Bislang war der gesamte Oberbau, den die Fahrwegplatte 3 zeigt, zusammen mit dem tragenden Längsrohr, das bisher üblicherweise einen trapezförmigen, nach oben erweiterten Querschnitt aufwies, als einteiliges Bauteil gefertigt worden, was eine sinnvolle Schleuderbetonfertigung nahezu unmöglich machte. Darüber hinaus musste dieses Bauteil ja in jedem Fall unabhängig von seiner Art der Fertigung als ganzes gehandhabt werden. Das hohe Gewicht wegen der erhöhten Wandstärken der gerüttelten Spannbetonlängsträger in Verbindung mit dem Gewicht der daran einstückig befestigten Fahrwegplatten macht die Verlegung solcher Fertigteil-Fahrwegträger mit einer Baulänge von etwa 20 m - 31 m zu einem höchst komplizierten Einbauverfahren, ebenso die Präzision der Fahrwegsplattenoberfläche.The guideway construction shown in Figures 1 and 2 for an elevated Route guidance - the several meter high support 1 is only hinted at in FIG. 2 shown and completely omitted in Fig. 1 - consists in essentially from a prestressed concrete support pipe 2 and as separate components manufactured guideway slabs 3, these guideway slabs not being of the same length how the prestressed concrete support tube 2 are formed, but from individual plate segments be produced with a correspondingly shorter length. This makes possible, regardless of the production of these track slabs 3 as reinforced concrete slabs or, as shown, as a sheet steel construction, a considerably easier processing of the track slabs. In particular, however, enables complete separation the guideway slabs and the actual side member are designed as Longitudinal beam as, at least approximately symmetrical and therefore only slight Unbalancing pipe, which consequently by means of centrifugal concrete production can be manufactured. So far, the entire superstructure was the track slab 3 shows, together with the supporting longitudinal tube, which has hitherto been customary had a trapezoidal, enlarged cross-section as a one-piece Component has been made, which makes a meaningful centrifugal concrete production almost impossible made. In addition, this component had to be independent in every case be handled as a whole by its type of manufacture. The high weight because of the increased wall thickness of the shaken prestressed concrete Connection with the weight of the track plates attached in one piece makes the laying of such precast track beams with a length of about 20 m - 31 m for a highly complicated installation process, as is the precision the guideway surface.

Zur Bildung der Auflageschultern 4, an denen entsprechende Auflagerabschnitte 5 der Fahrwegplatten 3 angeschraubt werden können, bedarf es lediglich gering über die zylindrische Rohrform des Spannbetontragrohrs 2 überstehender Verstärkungsrippen 6, die eine nennenswerte Unwucht nicht mit sich bringen, jedenfalls keine Unwucht und keine Unsymmetrie in dem Sinne, dass sie einer Schleuderbetonfertigung entgegen stünde.To form the support shoulders 4 on which corresponding support sections 5 the guideway plates 3 can be screwed on, it only requires a small amount reinforcing ribs projecting over the cylindrical tube shape of the prestressed concrete support tube 2 6, which do not bring any significant imbalance, at least no unbalance and no asymmetry in the sense that it is a centrifugal concrete production would be contrary.

Durch die Schleuderbetonfertigung ergibt sich ein durchgehender großer innerer Hohlraum 7, der zur Verlegung von Kabeln und Versorgungsleitungen dienen kann. Bei der Schleuderbetonfertigung des Spannbetontragrohrs 2 werden im Abstützbereich auf den Pfeilern 1, also im allgemeinen endseitig an den 20 m - 31 m langen Spannbetontragrohren Gewindebuchsen 8 eingelegt, in welche Verankerungsstäbe 9 eingeschraubt werden können. Diese dienen zur Verankerung in Stützkonsolen 10 mit Hilfe derer das Spannbetontragrohr 2 mit der Fahrwegplatte 3 auf den Stützen 1 abgestützt ist. Die dabei zusätzlich vorgesehenen, vorzugsweise gefederten, Stützfüße 11 sind an sich bekannt und brauchen daher an dieser Stelle nicht näher beschrieben werden. Die erfindungsgemäße Trennung der Fahrwegplatten von den Spannbetontragrohren 2 ermöglicht eine sehr einfache Fahrbahnüberhöhung in Kurven, wie dies in den Figuren 3 bis 5 dargestellt ist. Zu diesem Zweck braucht man nur Keilplatten 12 und eine zusätzliche Distanzplatte 13 im Befestigungsbereich der Fahrwegplatte 3 am Stützrohr 2 zwischenzuordnen. Stattdessen oder gegebenenfalls auch zusätzlich dazu kann gemäß Fig. 6 auch vorgesehen sein, dass das Spannbetontragrohr um seine Längsachse verdreht ist, also beispielsweise entsprechend verdreht an die Konsole 10 anbetoniert ist. Von besonderem Vorteil ist die geteilte Ausbildung der Fahrwegplatten als einzelnen kurze Plattensegmente speziell bei dieser Fahrwegüberhöhung gemäß den Fig. 3 bis 5, da hierdurch die Neigung nicht konstant innerhalb eines Fertigteil-Fahrwegträgers mit 20 m - 31 m Länge gleich bleiben muss, sondern die Plattensegmente von jeweils etwa 6,20 m unterschiedliche Neigungen aufweisen könnte.The production of centrifugal concrete results in a large, continuous interior Cavity 7, which are used to lay cables and supply lines can. During the centrifugal concrete production of the prestressed concrete support pipe 2 are in the support area on the pillars 1, generally at the ends at 20 m - 31 m long prestressed concrete support pipes threaded bushings 8 inserted into which anchoring rods 9 can be screwed. These are used for anchoring in Support brackets 10 with the help of which the prestressed concrete support pipe 2 with the track slab 3 is supported on the supports 1. The additionally provided, preferably spring-loaded, support feet 11 are known per se and therefore need this Not be described in more detail. The separation of the invention Track slabs from the prestressed concrete support pipes 2 enable a very simple Elevation of the carriageway in curves, as shown in FIGS. 3 to 5. To for this purpose one only needs wedge plates 12 and an additional spacer plate 13 in the fastening area of the track plate 3 on the support tube 2. Instead of this, or possibly also in addition to it, according to FIG. 6 it can also be provided that the prestressed concrete support tube rotates about its longitudinal axis is, for example, concreted accordingly to the console 10 is. The split design of the guideway slabs is particularly advantageous as individual short plate segments especially for this cant track increase 3 to 5, as this means that the inclination is not constant within one Precast track with 20 m - 31 m length must remain the same, but the Plate segments of approximately 6.20 m each have different inclinations could.

In den Fig. 7 und 8 ist schematisch eine Aufsicht bzw. ein Schnitt durch einen Fahrweg bei ebenerdiger Fahrwegführung dargestellt. Hierbei erkennt man eine oder mehrere Fahrwegplatten 3 mit etwa 6,20 m Länge, die über zwei parallel in Abstand zueinander angeordnete und durch ein Rechteckstahlrohr 14 miteinander am Auflager verschraubte Spannbetonrohre 2' direkte auf dem Bodenfundament 15 aufgelagert ist. Bodenfundamente 15, die zusätzlich noch mit Verankerungspfeilern 16 versehen sein können, müssen nur jeweils in einem Abstand, der der Länge eines Fertigteil-Fahrwegträgers, also im gezeigten Ausführungsbeispiel etwa 20 m - 31 m vorgesehen werden, während bisher bei der Abstützung der Fertigteil-Fahrwegträger mit Hilfe von in 3-Meter-Abständen angeordneten Querstützwänden nahezu zehnmal so viele Fundamente erforderlich waren. Neben dem inneren durchgehenden Hohlraum 7' der im wesentlichen als Rechteckrohre ausgebildeten Spannbetontragrohre 2' eignet sich besonders auch der Zwischenraum zwischen den Spannbeton - Rechteckträgern zur Aufnahme von Kabeln und Versorgungsleitungen.7 and 8 is a schematic view or a section through a Route shown at ground level route guidance. Here you can see one or several guideway slabs 3 with a length of about 6.20 m, which are parallel over two Distance from each other and through a rectangular steel tube 14 with each other Prestressed concrete pipes 2 'screwed to the support directly on the floor foundation 15 is supported. Floor foundations 15, which also have anchoring piers 16 can only be provided at a distance that the Length of a prefabricated guideway girder, i.e. in the exemplary embodiment shown about 20 m - 31 m can be provided, while previously supporting the Prefabricated guideway girders with the help of transverse support walls arranged at 3-meter intervals almost ten times as many foundations were required. Next the inner continuous cavity 7 'which is essentially a rectangular tube trained pre-stressed concrete support pipes 2 ', the space is also particularly suitable between the prestressed concrete rectangular beams to hold cables and supply lines.

In Fig. 9 ist ein der Fig. 7 entsprechender Schnitt dargestellt, wobei durch eine auf dem Fundament 15 angeordnete Keilplatte 17 eine Fahrwegneigung als Kurvenüberhöhung erzielt wird.In Fig. 9 a section corresponding to Fig. 7 is shown, with a through the wedge plate 17 arranged on the foundation 15 has a path inclination as curve elevation is achieved.

Die Fig. 10 zeigt einen vergrößerten Schnitt durch ein Spannbetontragrohr 2, in dem auch die in unterschiedlichen kreiszylindrischen Ebenen 18 und 19 angeordneten Spannstähle 20 bzw. 21 mit angedeutet sind. Die Spannstähle sind dabei in der unteren, den Auflageschultern 4 abgelegenen, Hälfte des Spannbetontragrohrs 2 dichter gepackt, gegebenenfalls auch stärker ausgebildet, um in diesem unteren besonders stark auf Zug durch das auflastende Gewicht beanspruchten Bereich eine erhöhte Bewehrung zu erzielen. Diese unsymmetrische Verteilung der Bewehrung kann nun in Verbindung mit einer unsymmetrischen Verteilung der Stützrippen 22 zur Versteifung des Formblechs 23 innerhalb einer Schleuderbetonform 24 gemäß Fig. 11 dazu ausgenutzt werden, dass das erhöhte Stahlgewicht im unteren Bereich des zu fertigenden Spannbetontragrohrs das erhöhte Betongewicht im Bereich der Auflageschultern und der überstehenden Verstärkungsrippen 6 gerade ausgleicht, so dass eine Unwucht vermieden ist und demzufolge die Schleuderbetonfertigung in besonders einfacher Weise und mit besonders hohen Rotationsgeschwindigkeiten möglich ist.10 shows an enlarged section through a prestressed concrete support pipe 2, in which also arranged in different circular cylindrical planes 18 and 19 Prestressing steels 20 and 21 are also indicated. The prestressing steels are in the lower, the support shoulders 4 remote half of the prestressed concrete support pipe 2 packed more densely, possibly also more trained to be in this the lower ones are particularly stressed by tension due to the weight Area to achieve increased reinforcement. This asymmetrical distribution the reinforcement can now be combined with an asymmetrical distribution of the Supporting ribs 22 for stiffening the shaped plate 23 within a spun concrete form 24 according to FIG. 11 can be used to increase the steel weight in the lower area of the prestressed concrete support pipe to be manufactured Concrete weight in the area of the support shoulders and the protruding reinforcing ribs 6 just compensates so that an unbalance is avoided and consequently centrifugal concrete production in a particularly simple manner and with special high rotational speeds is possible.
