Description

Die Erfindung betrifft einen Bahnsteig, von dessen Fundamenten Sockel aufragen mit mindestens Zwei Längsträgern, mit Ausgleichsmitteln und mit mindestens einer von den Längsträgern getragenen Betonplatte.The invention relates to a platform, from the foundations of which protrude bases with at least two longitudinal beams, with compensating means and with at least one concrete slab carried by the longitudinal beams.

DE 38 26 096 A1 beschreibt einen Bausatz und ein Verfahren zur Herstellung eines Bahnsteigs. Der in Zulieferwerkstätten vorgefertigte Bausatz besteht im wesentlichen aus Betonsockeln, die in vordefinierten Abständen auf das Erdreich oder ein Fundament gesetzt werden, darauf zu befestigenden Längsträgern und die Längsträger quer überdeckenden, beidseitig überkragenden Betonplatten. Als Fundamente können unterhalb der Betonsockel Bohrpfähle vorgesehen sein. Die Betonsockel sind an ihrem unteren Ende durch ein horizontal verlaufendes Joch verbunden, von dem sie nach oben aufragen. Die Längsträger, von denen mindestens zwei parallel zueinander angeordnet sind, liegen mit ihren Enden auf je einem Betonsockel auf. Die Größe der einzelnen auf den Längsträgern aufliegenden Betonplatten ist durch ihr Gewicht beschränkt. Die zwischen den einzelnen Betonplatten bestehenden Fugen haben Aussparungen, die durch eine Zementplombe verriegelt sind. Die Fugen sind außerdem mit elastischem Material vergossen, um eine ebene Lauffläche zu erhalten.DE 38 26 096 A1 describes a kit and a method for producing a platform. The kit, which is prefabricated in supplier workshops, essentially consists of concrete bases, which are placed at predefined intervals on the ground or a foundation, longitudinal members to be fastened thereon and the longitudinal members transversely overlapping, protruding concrete slabs on both sides. Bored piles can be provided as foundations below the concrete base. The concrete bases are connected at their lower ends by a horizontal yoke, from which they rise upwards. The longitudinal beams, of which at least two are arranged parallel to one another, lie with their ends on a concrete base. The size of the individual concrete slabs resting on the longitudinal beams is limited by their weight. The joints between the individual concrete slabs have recesses that are locked by a cement seal. The joints are also potted with elastic material to maintain a level tread.

Die vielen Fugen erfordern nicht nur bei der Errichtung des Bahnsteigs eine hohe Genauigkeit bei der Ausrichtung der Längsträger, um Stufen zwischen den Betonplatten zu verhindern, sie stellen darüberhinaus eine besonders witterungsanfällige Schwachstelle des Bahnsteigs dar. Salz und Feuchtigkeit können in die Fugen eindringen und von dort aus nicht nur die Betonplatte, sondern auch die darunterliegenden Längsträger und Pfosten zerstören. Darüberhinaus entsteht zwischen jeder Einheit aus verschiedenen Betonplatten und mindestens zwei Längsträgern an deren Stoßstelle zu der nächsten Einheit eine Schwachstelle, so daß eine Kraftübertragung über eine solche Einheit hinaus nicht erfolgt.The many joints not only require a high level of accuracy in the alignment of the longitudinal beams when erecting the platform to prevent steps between the concrete slabs, they are also a particularly vulnerable weak point of the platform. Salt and moisture can penetrate into the joints and from there not only destroy the concrete slab, but also the longitudinal members and posts underneath. In addition, a weak point arises between each unit from different concrete slabs and at least two side members at their abutment to the next unit, so that there is no power transmission beyond such a unit.

Der Erfindung liegt die Aufgabe zugrunde, einen kostengünstigen, gegenüber Umwelteinflüssen widerstandsfähigen Bahnsteig und ein Verfahren zu seiner Errichtung zur Verfügung zu stellen, wobei der Bahnsteig vielseitig einsetzbar sein soll und spätere Umbauten erleichtern soll.The invention has for its object to provide an inexpensive platform that is resistant to environmental influences and a method for its construction, the platform should be versatile and should facilitate subsequent conversions.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen der Patentansprüche 1 bzw. 9.This object is achieved according to the invention with the features of claims 1 and 9.

Bei der Erfindung ist der Bahnsteig eine Kombination solcher Komponenten, die als Fertigbauteile an die Baustelle gebracht werden mit aus Ortbeton auf der Baustelle erstellten Komponenten. Durch die Verwendung separater Fertigteile als Sockel wird es ermöglicht, verschieden hohe Bahnsteige zu errichten und dabei stets die gleichen Fundamente und Längsträger zu verwenden. Die Verbindung der Längsträger mit der Betonplatte aus Ortbeton zu einem Tragwerk verringert den erforderlichen Materialeinsatz für die Längsträger, die aus Stahlbeton oder Stahlprofilen bestehen. Dabei wirkt die die Verankerungselemente umschließende Betonplatte als Flansch für die Längsträger und sie erlaubt auch eine Kraft- und Momentenübertragung über die Stoßstellen zweier hintereinander liegender Längsträger hinweg.In the invention, the platform is a combination such components that are brought to the construction site as prefabricated components with components created from in-situ concrete on the construction site. The use of separate prefabricated parts as a base makes it possible to erect platforms of different heights and always use the same foundations and side members. The connection of the side members with the concrete slab made of in-situ concrete to a supporting structure reduces the material required for the side members, which consist of reinforced concrete or steel profiles. The concrete slab enclosing the anchoring elements acts as a flange for the side members and it also allows force and torque transmission across the joints of two side members lying one behind the other.

In Kurvenbereichen bilden die Längsträger einen Polygonzug, wobei die Längsträger tangential zu einer Parallelen an den Gleiskörper verlaufen. Da die Betonplatte am Ort hergestellt wird, kann sie durchgehend ausgebildet sein. Durch die Fertigung der Betonplatte am Errichtungsort ist eine Anpassung der Betonplatte an den Kurvenbereich leichter möglich.The longitudinal beams form a polygon in curve areas, the longitudinal beams being tangential to a parallel to the track body. Since the concrete slab is made on site, it can be continuous. By manufacturing the concrete slab at the place of installation, it is easier to adapt the concrete slab to the curve area.

Sollte es bei einem Wechsel der an dem Bahnsteig haltenden Fahrzeugtypen erforderlich sein, den Bahnsteig der Höhe nach anzupassen, so erlaubt die Verbindung von Betonplatte und Längsträgern zu einem Tragwerk, den ganzen Oberbau des Bahnsteigs mittels hydraulischer Pressen anzuheben und die als separate Fertigteile angeordneten Sockel durch Sockel einer anderen Höhe zu ersetzen. Dabei können der Oberbau und die Fundamente des Bahnsteigs weiter verwendet werden. Bei einem Umbau des Bahnsteigs werden so Kosten eingespart und die Umbauzeit verringert.If it is necessary to adjust the height of the platform when changing the type of vehicle stopping on the platform, the connection of the concrete slab and side members to a supporting structure allows the entire superstructure of the platform to be lifted by means of hydraulic presses and the bases arranged as separate finished parts To replace a base of a different height. The superstructure and the foundations of the platform can continue to be used. When the platform is converted, costs are saved and the conversion time is reduced.

Damit das Ausrichten der Pfosten erleichtert wird, können sich mehrere Pfosten auf einem gemeinsamen Fundament abstützen.To make it easier to align the posts, several posts can be supported on a common foundation.

Der erfindungsgemäße Bahnsteig verbindet die Vorteile einer Fertigbauweise mit den Vorteilen der Bauweise am Errichtungsort. Der Bahnsteig hat eine durchlaufende Betonplatte, die unempfindlich gegen Korrosion und Witterungseinflüsse ist, und er kann wegen der verwendeten Fertigbauteile in einer kurzen Zeit errichtet werden.The platform according to the invention combines the advantages of a prefabricated construction with the advantages of the construction at the place of construction. The platform has a continuous concrete slab that is insensitive to corrosion and weathering, and it can be erected in a short time due to the prefabricated components used.

Bei einer bevorzugten Ausführungsform weisen die Längsträger in ihrem oberen Bereich auf der den jeweils anderen Längsträgern zugeordneten Seite Nuten auf, die zur Aufnahme von Verschalungsteilen für die Herstellung der Betonplatte aus Ortbeton dienen. In diese Nuten kann eine verlorene Schalung eingesetzt werden, so daß in dem Bereich zwischen den Längsträgern die Verschalung für die Betonplatte leicht und kostengünstig erstellt werden kann.In a preferred embodiment, the longitudinal members have grooves in their upper region on the side assigned to the respective other longitudinal members, which are used to receive formwork parts for the production of the concrete slab from in-situ concrete. A lost formwork can be inserted into these grooves so that the formwork for the concrete slab can be created easily and inexpensively in the area between the longitudinal beams.

Bei der Errichtung des Bahnsteigs nach dem erfindungsgemäßen Verfahren werden nach dem Setzen der Fundamente, die vorgefertigt oder am Ort gegossen sein können, die Sockel aufgesetzt, wobei für jeden der mindestens zwei nebeneinanderliegenden Längsträger mindestens zwei Sockel angeordnet werden. Nach dem Überprüfen der Höhe der Sockel und ggf. dem Ausgleich von Abweichungen mittels Distanzelementen werden die Längsträger aufgelegt. Anschließend wird die Schalung für die Betonplatte aufgebaut. Dazu wird auch die verlorene Schalung benutzt. Damit während der Betonierarbeiten der Bahnbetrieb nicht gestört wird, ist vorgesehen, beim Betonieren der in Richtung auf die Gleise überkragenden Bereiche der Betonplatte eine verfahrbare Schalung zu verwenden. Die verfahrbare Schalung ist auf eigenen Schienen geführt und erstreckt sich im wesentlichen nur unterhalb der Betonplatte, so daß der Bahnbetrieb nicht beeinträchtigt wird. Nachdem der Beton eine ausreichende Festigkeit erreicht hat, kann die verfahrbare Verschalung schnell abgesenkt, verfahren und an einem anderen Bereich der Betonplatte wieder angehoben werden.When the platform is erected using the method according to the invention, after the foundations, which can be prefabricated or cast on site, the bases are put on, at least two bases being arranged for each of the at least two adjacent longitudinal beams. After checking the height of the base and, if necessary, compensating for deviations using spacer elements, the side members are put on. The formwork for the concrete slab is then built up. The lost formwork is also used for this. So that the railway operations are not disturbed during the concreting work, Use movable formwork when concreting the areas of the concrete slab projecting towards the tracks. The movable formwork is guided on its own rails and extends essentially only below the concrete slab, so that the railway operation is not affected. After the concrete has reached a sufficient strength, the movable formwork can be quickly lowered, moved and raised again in another area of the concrete slab.

Der in einer ersten Ausführungsform in Fig. 1 im Schnitt gezeigte Bahnsteig 10 ist neben einem Gleiskörper 20 angeordnet. Der Bahnsteig 10 verläuft im wesentlichen parallel zu dem Gleiskörper 20 und weist mehrere Fundamente 30 auf, die sich jeweils in einer Vertikalebene senkrecht zu dem Gleiskörper 20 erstrecken und längs des Gleiskörpers 20 verteilt angeordnet sind. Jedes Fundament 30 steht auf einer Kiesschicht 32 oder auf einem auf andere Weise vorbereiteten Untergrund. Auf der Oberseite 34 der Fundamente 30 sind Sockel 36 angeordnet, die gegenüber den Fundamenten 30 gegen seitliches Verschieben mit Sicherungselementen 38 gesichert sind. Auf den Sockeln liegen zum Ausgleich von Höhenabweichungen Distanzelemente 40 auf. Oberhalb der Distanzelemente 40 und mit den Sockeln 36 verbunden sind Längsträger 42 angeordnet, die zusammen mit einer Betonplatte 44 ein Tragwerk 46 bilden. Auf der Oberseite 48 der Betonplatte 44 ist ein Belag 50 aufgebracht, der die Lauffläche des Bahnsteigs 10 bildet.The platform 10 shown in section in a first embodiment in FIG. 1 is arranged next to a track body 20. The platform 10 runs essentially parallel to the track body 20 and has a plurality of foundations 30, each of which is in a vertical plane Extend perpendicular to the track body 20 and are arranged distributed along the track body 20. Each foundation 30 stands on a gravel layer 32 or on a surface prepared in another way. On the upper side 34 of the foundations 30, bases 36 are arranged, which are secured with respect to the foundations 30 against lateral displacement with securing elements 38. Spacers 40 rest on the bases to compensate for height deviations. Longitudinal members 42 are arranged above the spacer elements 40 and connected to the bases 36, which together with a concrete plate 44 form a supporting structure 46. On the upper side 48 of the concrete slab 44, a covering 50 is applied, which forms the running surface of the platform 10.

Die den Belag 50 tragende Betonplatte 44 kragt auf der dem Gleiskörper 20 zugewandten Seite des dem Gleiskörper 20 zugewandten Längsträgers 42 frei über, so daß unterhalb der Betonplatte 44 ein Fluchttunnel 52 gebildet ist. Auch auf der dem Gleiskörper 20 abgewandten Seite des dem Gleiskörper 20 abgewandten Längsträgers 42 kragt die Betonplatte 44 über den Längsträger 42 hinaus. Die durch die Belastung des Bahnsteigs 10 auftretenden Kräfte werden in die Längsträger 42 eingeleitet. Die in Fig. 1 gezeigten aus Stahlbeton vorgefertigten Längsträger 42 weisen an ihrer Oberseite abstehende Verankerungselemente 54 auf, die als Muniereisen in die Längsträger 42 einbetoniert sind und beim Gießen der Betonplatte 44 von dem Ortbeton der Betonplatte 44 umschlossen werden. Dadurch erhält das Tragwerk 46 aus den vorgefertigten Längsträgern 42 und der am Ort gegossenen Betonplatte 44 eine zusammenhängende Struktur, so daß die Belastungen verteilt werden und die Längsträger 42 sowie die Betonplatte 44 schwächer dimensioniert werden können als die Einzelbauteile des bekannten Bausatzes.The concrete plate 44 carrying the covering 50 projects freely over the side of the longitudinal member 42 facing the track body 20, so that an escape tunnel 52 is formed below the concrete plate 44. On the side of the longitudinal beam 42 facing away from the track body 20, the concrete slab 44 also projects beyond the longitudinal beam 42. The forces arising from the loading of the platform 10 are introduced into the side members 42. The longitudinal beams 42 prefabricated from reinforced concrete shown in FIG. 1 have anchoring elements 54 protruding on their upper side, which are concreted into the longitudinal beams 42 as ammunition iron and are enclosed by the in-situ concrete of the concrete plate 44 when the concrete plate 44 is poured. This gives the structure 46 of the prefabricated side members 42 and the cast in place 44 a coherent structure, so that the loads are distributed and the side members 42 and the concrete plate 44 can be dimensioned weaker than the individual components of the known kit.

Zur Sicherung der Längsträger 42 und damit des Tragwerks 46 gegen Verschieben auf den Sockeln 36 weisen die Längsträger an ihren Stirnseiten 56 Aussparungen 58 auf, in die Dollen oder Splinte als Sicherungselemente 60 eingreifen. Zur Aufnahme der Sicherungselemente 60 weisen die quaderförmigen Sockel 36 einen zentral angeordneten Kanal 62 auf, der von der Oberseite 64 bis zur Unterseite 66 des Sockels 36 durchgeht.To secure the side members 42 and thus the supporting structure 46 against displacement on the bases 36, the side members 56 have cutouts 58 on their end faces, into which oarlocks or split pins engage as securing elements 60. To accommodate the securing elements 60, the cuboid bases 36 have a centrally arranged channel 62 which extends from the top 64 to the bottom 66 of the base 36.

Zur Aufnahme der Sicherungselemente 38, die den Sockel 36 gegenüber dem Fundament sichern und die ebenfalls Dollen oder Splinte sein können, sind in dem Sockel 36 parallel verlaufende durchgehende Kanäle 68 angeordnet, die seitlich neben dem Längsträger 42 in den Sockelecken liegen und zu dem zentral angeordneten Kanal 62 den gleichen Abstand aufweisen. Das Fundament weist acht vertikale Schächte 70 auf, die entsprechend der Verteilung der durchgehenden Kanäle 68 in den Sockeln 36 in zwei Gruppen angeordnet sind und in die die Sicherungselemente 38 eingreifen. Die Schächte 70 gehen durch die gesamte Höhe des Fundaments 30 hindurch.To accommodate the securing elements 38, which secure the base 36 with respect to the foundation and which can also be oarlocks or split pins, parallel through-channels 68 are arranged in the base 36, which lie laterally next to the side member 42 in the base corners and are arranged centrally to it Channel 62 have the same distance. The foundation has eight vertical shafts 70, which are arranged in two groups according to the distribution of the continuous channels 68 in the bases 36 and in which the securing elements 38 engage. The shafts 70 pass through the entire height of the foundation 30.

Die Sicherungselemente stehen lose auf dem Untergrund des Fundaments auf und erstrecken sich bis nahe der Oberseite des Blockes. An ihren Enden sind sie nicht mit Verankerungselementen versehen.The securing elements stand loosely on the base of the foundation and extend to near the top of the block. They are not provided with anchoring elements at their ends.

Im Gegensatz zu den Sockeln 36, die vorzugsweise aus Stahlbeton hergestellt werden, bestehen die Distanzelemente 40 aus Metall. Die Distanzelemente 40 weisen wie die Sockel 36 einen zentralen Kanal und durchgehende Kanäle auf, jedoch sind sie flach ausgebildet, damit sie zum Ausgleich von Höhendifferenzen verwendet werden können. Die Distanzelemente 40 sind Scheiben, die in der für den Höhenausgleich erforderlichen Anzahl aufeinandergelegt werden können.In contrast to the bases 36, which are preferably made of reinforced concrete, the spacer elements 40 consist of metal. Like the base 36, the spacer elements 40 have a central channel and continuous channels, but they are designed to be flat so that they can be used to compensate for height differences. The spacer elements 40 are disks that in the number required for height compensation can be stacked on top of one another.

Die Sockel 36 und das Tragwerk 46 werden von Fundamenten 30 getragen, von denen eines in Fig. 1 in Seitenansicht gezeigt ist. Damit eine maschinelle Reinigung des Gleiskörpers 20 möglich ist, reicht das Fundament 30 nicht bis in den Bereich der dem Gleiskörper 20 zugewandten Längsseite 86 der Betonplatte 44, sondern es hält zu dem Gleiskörper einen Abstand ein. Das Fundament 30 ist ein aus Stahlbeton vorgefertigtes Fertigteil, das quaderförmig ausgebildet ist. Das Fundament 30 dient der Abstützung zweier in einer zu dem Gleiskörper 20 senkrechten Vertikalebene angeordneter Sockel 36.The base 36 and the supporting structure 46 are supported by foundations 30, one of which is shown in side view in FIG. 1. So that a mechanical cleaning of the track body 20 is possible, the foundation 30 does not extend into the area of the long side 86 of the concrete slab 44 facing the track body 20, but it maintains a distance from the track body. The foundation 30 is a prefabricated part which is prefabricated from reinforced concrete and has a cuboid shape. The foundation 30 serves to support two bases 36 arranged in a vertical plane perpendicular to the track body 20.

In Fig. 4 ist eine zweite Ausführungsform des Bahnsteigs 10 während des Baus gezeigt. Der Bahnsteig 10 weist separate Fundamente 30 für jeden Sockel 36 auf. Die Sockel 36 sind auf den Fundamenten 30 mit Sicherungselementen 38 wie in der ersten Ausführungsform gesichert. Auf der Oberseite 64 der Sockel 36 liegen Längsträger 42 auf, die mit einer Betonplatte 44 zu einem Tragwerk verbunden sind. Die Betonplatte 44 ist als Ortbetonplatte gegossen, wobei der zwischen den Längsträgern 42 des Bahnsteigs 10 liegende Bereich a beim Betonieren von einer verlorenen Schalung 72 abgestützt ist und die überkragenden Bereiche b und c jeweils mit einer verfahrbaren Schalung 74 abgestützt sind. Die verlorene Schalung 72 greift in Nuten 76 ein, die auf der dem Bereich a zugewandten Seite der Längsträger 42 in deren oberen Bereich gebildet sind. Die Abstützung der verlorenen Schalung 72 in den Nuten 76 erlaubt eine einfache, kostengünstige und schnelle Montage der für die Betonierung der Ortbetonplatte 44 erforderlichen forderlichen Schalung. Die verfahrbare Schalung 74 besteht aus einem Gestell 78, das über Rollen 80 in eigenen Schienen 82 geführt ist. Eine der beiden Schienen 82 je verfahrbarer Schalung 74 ist auf den Fundamenten 30 abgestützt und die andere verläuft entlang dem Gleiskörper auf dem Boden aufliegend. Auf dem Gestell 78 liegt eine Schaltafel 84 auf, die auch die Längsseiten 86 der Betonplattte 44 umgreift. Die Schaltafel 84 kann abgesenkt und nach dem Verfahren in den Schienen 82 wieder angehoben werden.4 shows a second embodiment of the platform 10 during construction. The platform 10 has separate foundations 30 for each base 36. The bases 36 are secured on the foundations 30 with securing elements 38 as in the first embodiment. On the top 64 of the base 36 there are longitudinal beams 42 which are connected to a concrete plate 44 to form a supporting structure. The concrete slab 44 is cast as an in-situ concrete slab, the area a lying between the longitudinal beams 42 of the platform 10 being supported by a lost formwork 72 during concreting and the projecting areas b and c each being supported by a movable formwork 74. The lost formwork 72 engages in grooves 76 which are formed on the side of the longitudinal beams 42 facing the region a in the upper region thereof. The support of the lost formwork 72 in the grooves 76 allows a simple, inexpensive and quick assembly of the necessary for the concreting of the in-situ concrete slab 44 required formwork. The movable formwork 74 consists of a frame 78 which is guided on rollers 80 in its own rails 82. One of the two rails 82 for each movable formwork 74 is supported on the foundations 30 and the other runs along the track body lying on the ground. On the frame 78 there is a formwork panel 84 which also encompasses the long sides 86 of the concrete slab 44. The formwork panel 84 can be lowered and raised again in the rails 82 after the movement.

Die Betonplatte 44 des in Fig. 4 gezeigten Bahnsteigs 10 ist etwa in der Mitte leicht abgeknickt, so daß der Bahnsteig 10 etwa in seiner Mitte eine Senke bildet, um über einen Ablaufkanal eine Entwässerung des Bahnsteigs 10 zu bewirken. In üblicher Weise ist der Bahnsteig 10 auch mit Pfosten 88 zur Anbringung von Hinweistafeln oder ähnlichem und mit einem Kabelkanal 90 versehen.The concrete slab 44 of the platform 10 shown in FIG. 4 is slightly kinked approximately in the middle, so that the platform 10 forms a depression approximately in the middle in order to effect a drainage of the platform 10 via a drainage channel. In the usual way, the platform 10 is also provided with posts 88 for attaching notice boards or the like and with a cable duct 90.

Zur Herstellung des Bahnsteigs 10 werden nach dem Setzen der Fundamente 30 die separaten Sockel 36 aufgesetzt und anschließend die Längsträger 42 auf die Sockel 36 aufgelegt. Das Bedecken der Längsträger 42 mit der Betonplatte 44 erfolgt durch Gießen der Betonplatte 44 aus Ortbeton, wobei die aufragenden Verankerungselemente 54 umschlossen werden. Beim Gießen der Ortbetonplatte 44 wird der Beton mittels einer Schalung abgestützt.To manufacture the platform 10, the separate bases 36 are placed after the foundations 30 have been placed, and then the longitudinal members 42 are placed on the bases 36. The longitudinal beams 42 are covered with the concrete slab 44 by pouring the concrete slab 44 from in-situ concrete, the upstanding anchoring elements 54 being enclosed. When pouring the in-situ concrete slab 44, the concrete is supported by means of a formwork.

Der zwischen den Längsträgern 42 liegende Bereich a der Betonplatte wird mittels der verlorenen Schalung 72 abgestützt, die in den Nuten 76 gehalten ist. Die überkragenden Bereiche der Betonplatte 44 sind dagegen mittels der verfahrbaren Schalung 74 unterstützt.The area a of the concrete slab lying between the longitudinal beams 42 is supported by the lost formwork 72 which is held in the grooves 76. The projecting areas of the concrete slab 44, on the other hand, are supported by the movable formwork 74.

Wenn durch die Einführung neuer Straßenbahnwagen die Anpassung des Bahnsteigs 10 der Höhe nach erforderlich wird, werden die lose eingesteckten Sicherungselemente 38 aus den Fundamenten 30 und den Sockeln 36 nach oben herausgezogen. Es werden hydraulische Pressen aufgestellt, mittels derer das Tragwerk 46 angehoben wird, bis die Sicherungselemente 60 die Sockel 36 freigeben. Die Sockel 36 werden durch Sockel 36 mit einer anderen Höhe ersetzt oder es werden Distanzelemente 40 aufgelegt oder entfernt. Anschließend wird das Tragwerk 46 abgesenkt, bis es wieder auf den Sockeln 36 aufliegt, und es werden die Sicherungselemente 38 in die Kanäle 68 und Schächte 70 gesteckt.If the height of the platform 10 needs to be adjusted due to the introduction of new tram cars, the loosely inserted securing elements 38 are pulled up out of the foundations 30 and the bases 36. Hydraulic presses are set up, by means of which the supporting structure 46 is raised until the securing elements 60 release the base 36. The bases 36 are replaced by bases 36 with a different height, or spacer elements 40 are placed or removed. The supporting structure 46 is then lowered until it rests on the bases 36, and the securing elements 38 are inserted into the channels 68 and shafts 70.
