Abstract
Description
Die Erfindung bezieht sich auf eine betonlose Schwelle für eine feste Fahrbahn, in
der durch Schienen zu einem Gleisrost vormontierte Schwellen nach dem Ausrichten
des Gleisrostes über einer Tragplatte zumindest teilweise in eine Fahrbahnplatte
einbetoniert sind oder nach dem sogenannten Züblin-Verfahren in eine
vorbetonierte Platte eingerüttelt werden, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a concrete sleeper for a fixed carriageway, in
the pre-assembled by rails to a track grid thresholds after alignment
the track grid on a support plate at least partially in a carriageway slab
or in accordance with the so-called Züblin method in a
vorbetonierte plate are vibrated, according to the preamble of
Neben Ausführungsformen von Betonschwellen - unabhängig davon, ob es sich um Einblock- oder Zweiblockschwellen handelt - bei denen die Armierung einfache Baustahlstangen sind, die durch Bügel miteinander verbunden sein können, ist in der Patentschrift DE 198 16 407 C1 auch bereits eine Schwelle vorgeschlagen worden, bei der die Bewehrung durch sogenannte Gitterträger gebildet ist, die bevorzugt teilweise aus den nur unvollständig ausbetonierten Betonschwellen unten heraussteht, um einen besseren Verbund zur Vergussmasse der eigentlichen Fahrbahn zu erzielen. Nach wie vor ist die Schwelle aber zumindest teilweise im oberen Bereich, also dort wo die Schienenauflager liegen, als Betonschwelle ausgebildet. Nur im unteren Bereich ist dieser Beton bei der Schwelle ausgespart worden.In addition to embodiments of concrete sleepers - regardless of whether it is are single-block or double-block sleepers - where the reinforcement is simple Construction steel bars are, which can be connected to each other by brackets, is in the patent DE 198 16 407 C1 already proposed a threshold in which the reinforcement is formed by so-called lattice girders, the prefers partly from the incompletely concreted concrete sleepers below stands out, in order to better bond to the casting compound of the actual Roadway to achieve. Still, the threshold is at least partially in the upper area, ie where the rail supports lie, designed as a concrete sleeper. Only at the bottom of this concrete is recessed at the threshold Service.
Dies gilt sogar noch in erhöhtem Maße für eine Schwelle wie sie in der US 2 272 218 beschrieben ist. Dort sind Schienenbefestigungsplatten direkt auf die Schwellenarmierung aufgeschraubt, die dann allerdings zusammen mit diesen Schienenbefestigungsplatten im Beton einer normalen Einblockbetonschwelle vergossen sind. Ein irgendwie gearteter verbesserter Verbund einer solchen Schwelle bei Einbindung in eine feste Fahrbahn ist somit natürlich nicht mehr zu erzielen.This is even more true for a threshold as shown in US Pat. No. 2,272 218 is described. There are rail mounting plates directly on the Threshold armature screwed on, but then together with these Rail fastening plates in concrete of a normal single block concrete sleeper are shed. Some kind of improved composite of such Threshold for integration into a fixed carriageway is of course no longer possible achieve.
Eine betonlose Metallschwelle zeigt auch bereits die US-A-4,285,115. Bei dieser Konstruktion werden gewinkelte hohle Metallprofile, die zur Beschwerung mit Beton ausgegossen sein können, zu zick-zack förmigen Strukturen zusammengeschraubt und dienen dann als Schwellenrost zum Aufbringen der Schienen. Dieser aus den Metallprofilen gebildete Schwellenrost wird aber oben auf eine Fahrbahnplatte 30 aufgebracht und nicht, wie dies bei festen Fahrbahnen der Fall ist, vollständig in die Vergussmasse der Fahrbahnplatte eingebettet.A concrete-free metal sleeper already shows US-A-4,285,115. At this Construction will be angled hollow metal profiles, which will be weighted with concrete can be poured out, screwed together into zigzag-shaped structures and then serve as a threshold grating for applying the rails. This Threshold grid formed from the metal profiles but is on top of a carriageway slab 30 applied and not, as is the case with fixed roads, completely embedded in the potting compound of the carriageway slab.
Der Erfindung liegt die Aufgabe zugrunde, eine Schwelle für eine feste Fahrbahn so auszubilden, dass Sie einfacher herstellt werden kann und erheblich leichter ist, so dass der Antransport und die Verarbeitung an der Baustelle wesentlich einfacher erfolgen kann und dass sie einen besseren Verbund mit der Fahrbahnplatte ergibt.The invention is based on the object, a threshold for a fixed carriageway so that it can be made easier and is much easier so that the transport and processing at the construction site much easier can be done and that they have a better bond with the deck plate results.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass
- den Schwellenarmierungen und den Schienenbefestigungsplatten Abstandhalter, vorzugsweise in Form stehender Stahlstege oder Stahlkästen, zwischengeordnet sind, und
- die Schienenbefestigungsplatten mit angeschweißten gegebenenfalls die Abstandhalter durchsetzenden Betonankern, insbesondere Kopfbolzen zur Einbindung in die Fahrbahnplatte versehen sind.
- the threshold reinforcements and the rail mounting plates spacers, preferably in the form of standing steel webs or steel boxes, are interposed, and
- the rail mounting plates are provided with welded possibly the spacers passing through the concrete anchors, in particular head bolts for integration in the deck slab.
Gemäß der vorliegenden Erfindung besteht die Schwelle also nur noch aus der eigentlichen Schwellenarmierung ohne jegliche Betonumhüllung, wobei natürlich spezielle Vorkehrungen, nämlich ein Anschweißen der Schienenbefestigungsplatten erforderlich ist, um die Schiene mit dieser Armierung verbinden zu können. Das eigentliche Ausbetonieren erfolgt ausschließlich beim Betonieren der Fahrbahnplatte, wobei im Gegensatz zu der angesprochenen Anordnung nach der DE 198 16 407 C1 nicht nur der unten aus den Teilbetonierungen einer Betonschwelle herausstehende Teil der Schwellenarmierung in den Beton der Fahrbahnplatte eingebettet wird, sondern die gesamte Schwellenbewehrung. Dies erspart den ganzen Herstellungsschritt des Betonierens der Schwelle bzw. der Einzelblöcke der Schwelle und hat dabei den zusätzlichen Vorteil, dass die ja nur auf ihre Armierung reduzierten Schwellen - die natürlich auch nur für feste Fahrbahnen einsetzbar sind und nicht für übliche aufliegende Konstruktionen oder Schotterkonstruktionen - sehr viel leichter sind. Dies vereinfacht den Transport der Schwellen zu einer Gleisbaustelle ganz erheblich und darüber hinaus ist auch die Handhabung der vorgefertigten Gleisroste, die über einer festen Tragschicht mit Hilfe von Portalen oder Hebespindeln ausgerichtet und dann einbetoniert werden, wesentlich einfacher.According to the present invention, therefore, the threshold consists only of the actual threshold reinforcement without any concrete cladding, of course special precautions, namely welding the rail fastening plates is required to connect the rail with this reinforcement can. The actual concreting takes place exclusively when concreting the roadway slab, in contrast to the mentioned arrangement according to the DE 198 16 407 C1 not only the bottom of the partial concretions of a concrete sleeper protruding part of the threshold reinforcement into the concrete of the deck slab is embedded, but the entire threshold reinforcement. This saves the entire manufacturing step of concreting the threshold or individual blocks the threshold and has the added advantage that yes only on their armor reduced thresholds - which of course only for solid lanes can be used and not for conventional superposed structures or ballast constructions - are much easier. This simplifies the transport of Thresholds to a track construction site quite considerably and beyond that is also the Handling of prefabricated track grates, which over a solid base course with Help of portals or lifting spindles are aligned and then embedded in concrete, much easier.
Dadurch, dass die Schienenfußträger mit angeschweißten, gegebenenfalls die Abstandhalter durchsetzenden, Kopfbolzen oder anderer Betonanker zur Einbindung in die Fahrbahnplatte versehen sind ergibt sich ein besonders fester Verbund der Schienenbefestigungsplatten mit dem Beton der Fahrbahnplatte und damit eine besonders feste Halterung der Schienen.The fact that the rail support with welded, possibly the Spacers passing through, head bolts or other concrete anchor for integration provided in the deck slab results in a particularly strong bond the rail fastening plates with the concrete of the deck slab and thus a particularly firm mounting of the rails.
Mit besonderem Vorteil sollen dabei die Schienenbefestigungsplatten nicht unmittelbar auf den Schwellenarmierungen aufgeschweißt sein, sondern den Schwellenarmierungen und den Schienenbefestigungsplatten können in Ausgestaltung der Erfindung Abstandhalter, vorzugsweise in Form stehender Stahlplatten oder Stahlkästen zwischengeordnet sein.With special advantage, the rail mounting plates should not directly welded on the threshold reinforcements, but the threshold reinforcements and the rail fastening plates can in configuration the invention spacer, preferably in the form of standing steel plates or Steel boxes be interposed.
Gemäß einem ersten Ausführungsbeispiel der vorliegenden Erfindung kann die Bewehrung - ähnlich der bereits mehrfach angesprochenen DE 198 16 407 C1 - zwei parallel nebeneinander verlaufende Gitterträger mit jeweils drei die Kanten eines dreieckigen Prismas bildenden Längsstangen und zwei diese verbindenden Mäanderschlangen umfassen.According to a first embodiment of the present invention, the Reinforcement - similar to the already repeatedly discussed DE 198 16 407 C1 - two parallel lattice girders, each with three edges a triangular prism forming longitudinal bars and two connecting them Include meandering snakes.
Bei einer solchen Ausbildung mit Gitterträgern als Schwellenbewehrung können die Gitterträger darüber hinaus zusätzlich unten durch eine angeschweißte Mäanderschlange miteinander verbunden sein, wodurch eine entsprechende Stabilisierung im unteren Bereich der Bewehrung gegeben ist. Die entsprechende Stabilisierung im oberen Bereich ergibt sich durch die Abstandhalter.In such training with lattice girders as threshold reinforcement can In addition, the lattice girder down through a welded meander snake be connected to each other, creating a corresponding stabilization is given in the lower part of the reinforcement. The corresponding stabilization in the upper area results from the spacers.
Neben der Möglichkeit, auf die oberen Längsstangen der Gitterträger jeweils zwei beabstandete, quer zur Schwellenachse verlaufende Stahlplatten je Schienenfußträger aufzuschweißen, die die bereits angesprochenen Abstandhalter bilden, kann auch vorgesehen sein, dass die beiden Gitterträger durch im Wesentlichen U-förmige Bügel miteinander verbunden sind, auf deren obenliegende Basisschenkel die Abstandhalter aufgeschweißt sind. In diesem Fall erfolgt das Aufschweißen der Abstandhalter dann entweder quer zur Schwellenachse oder bevorzugt auch parallel zur Schwellenachse.In addition to the possibility of two on the upper longitudinal bars of the lattice girders spaced, transverse to the threshold axis extending steel plates per rail foot to weld on, which form the already mentioned spacers, can also be provided that the two lattice girders by essentially U-shaped brackets are connected to each other, on the upper base leg the spacers are welded on. In this case, the welding takes place the spacer then either transverse to the threshold axis or preferred also parallel to the threshold axis.
In manchen Anwendungsfällen ist es erwünscht, dass die Schienenbefestigungsplatten oberhalb der Vergussoberkante der Fahrbahnplatte liegen, was sich bei einer erfindungsgemäßen Konstruktion besonders einfach dadurch erzielen lässt, dass unter dem Schienenbefestigungsplatte ein über die Vergussoberkante überstehender Stahlkasten angeordnet ist. Dieser Stahlkasten kann entweder direkt auf der Schwellenarmierung aufgeschweißt sein, oder aber auf den bereits genannten Abstandhalter-Stahlplatten.In some applications, it is desirable that the rail mounting plates above the casting top of the deck slab lie, which is at particularly easy to achieve by a construction according to the invention that under the rail mounting plate over the Vergussoberkante protruding Steel box is arranged. This steel box can either be direct be welded on the Schwellenarmierung, or on the already mentioned Spacer steel plates.
Gemäß einem zweiten Ausführungsbeispiel der vorliegenden Erfindung kann die Schwellenarmierung wenigstens einen, vorzugsweise zwei parallel nebeneinander liegende, Profilträger umfassen, wobei die Profilträger unterschiedlich ausgebildet sein können. So eignen sich für die erfindungsgemäßen Zwecke sowohl Z-, U-, T-T-Profile oder aber auch einfache Winkelprofile. According to a second embodiment of the present invention, the Schwellenarmierung at least one, preferably two parallel to each other lying, profile carrier, wherein the profile carrier designed differently could be. For example, Z, U, T-T profiles are suitable for the purposes according to the invention or even simple angle profiles.
In Ausgestaltung der Erfindung hat es sich dabei als zweckmäßig erwiesen, dass die vertikalen oder zumindest teilweise vertikal verlaufenden Schenkel der Profilträger mit Löchern versehen sind, die sowohl zum Einlegen von Längsarmierungen der Fahrbahnplatte dienen, als auch einen besseren Verbund mit dem Beton der Fahrbahnplatte durch das Eindringen des Betons in diese Löcher bewirken.In an embodiment of the invention, it has proven to be expedient that the vertical or at least partially vertical legs of the profile carrier are provided with holes, both for inserting longitudinal reinforcements serve the deck slab, as well as a better bond with the concrete cause the deck slab by the penetration of the concrete in these holes.
Um eine leichtere und einfachere Verarbeitung an der Baustelle zu erzielen, hat es sich als zweckmäßig erwiesen, die vorgefertigten Gleisroste aus Schienen und Schwellen zunächst auf der Tragschicht der Fahrbahn abzustellen und erst sukzessive nach einem Vorausrichten anzuheben, auszurichten und dann das Vergießen der Schwellen in die Fahrbahnplatte zu bewerkstelligen.To achieve easier and easier processing on site, it has proved to be useful, the prefabricated track grates rails and First of all, turn off sleepers on the base course of the carriageway and only gradually after pre-aligning, raise, align and then shed the sleepers in the deck plate to accomplish.
Um dies auch bei den erfindungsgemäßen betonlosen Schwellen zu erreichen, kann - insbesondere dann, wenn an die Unterseite der Profilträger noch einer zusätzlichen Verankerung dienende Kopfbolzen angeschweißt sind - vorgesehen sein, dass die Profilträger mit vorzugsweise ebenfalls als T-Trägerabschnitte ausgebildeten Aufstellfüßen zum Aufstellen des Gleisrostes auf der Tragschicht versehen sind. Dabei versteht es sich von selbst, dass die Aufstellfüße natürlich höher sind als die Kopfbolzen, damit nicht ein Aufsetzen auf diesen Kopfbolzen mit der Gefahr einer Verbiegung oder eines Abbrechens stattfinden kann.In order to achieve this also in the concrete-free sleepers according to the invention, can - especially if, to the underside of the profile support nor an additional Anchoring serving head bolts are welded - provided be that the profile carrier with preferably also designed as a T-beam sections Provided feet for setting up the track grid on the support layer are. It goes without saying that the Aufstellfüße course higher are as the head bolts, so not a putting on this head bolt with the risk of bending or breaking off may take place.
Gemäß einem weiteren Ausführungsbeispiel kann es vorgesehen werden, seitlich an einen durchgehenden Profilträger im Bereich der Schienen kurze Profilträger zur Bildung einer verbreiterten Aufliegefläche für die Schienenfußplatten tragende herkömmliche Lager zu befestigen, vorzugsweise anzuschweißen.According to a further embodiment, it may be provided laterally to a continuous Profile carrier in the region of the rails short profile carrier to form a widened support surface for the Schienenfußplatten bearing conventional To fix bearing, preferably to weld.
Schließlich liegt es auch noch im Rahmen der Erfindung, Teile, die nicht korrosionsgeschützt in Beton eingebettet sind, ganz oder teilweise aus Edelstahl, wetterfestem Stahl, Stahl mit verzinkter oder sonstiger korrosionsverhindernder Oberflächenbeschichtung zu bestehen.Finally, it is also within the scope of the invention, parts that are not embedded in concrete corrosion protection, in whole or in part Made of stainless steel, weatherproof steel, galvanized steel or other corrosion-resistant surface coating.

Die in den Fig. 1 und 2 dargestellte betonlose Schwelle 1 besteht lediglich aus der
über die Schwellenlänge im Wesentlichen durchgehende Armierung, wobei angesichts
des fehlenden Ausbetonierens der Schwelle vor ihrer Verarbeitung an der
Baustelle eine Unterscheidung zwischen Monoblock- und Zweiblockschwellen überhaupt
nicht mehr gegeben ist. An die Schwellenbewehrung 2 ist über einen
Abstandhalter 3, der in den Fig. 1 und 2 durch zwei beabstandete Stahlstege 4
gebildet ist, ein Schienenbefestigungsplatte 5 angeschweißt, auf dem die Schiene
6 in herkömmlicher Weise befestigt werden kann. Beim Ausführungsbeispiel nach
den Fig. 1 und 2 besteht die Schwellenarmierung 2 aus zwei Gitterträgern 7 und 8,
von denen jeder aus drei die Kanten eines dreieckigen Prismas bildenden Längsstangen
9, 10, 11 und zwei diese verbindenden Mäanderschlangen 12, 13 besteht.
Die erfindungsgemäßen betonlosen Schwellen werden an der Baustelle zunächst
mit den Schienen zu einem Gleisrost vormontiert, der nach einer Ausrichtung
über einer vorzugsweise als hydraulisch gebundene Tragschicht ausgebildeten
festen Auflageschicht 27 in die Fahrbahnplatte 14 einbetoniert wird, wobei
üblicherweise, aber nicht zwingend wie sich aus anderen Ausführungsbeispielen
weiter unten ergeben wird, die Oberkante 15 der Betonschicht bis zur Unterkante
der Schienenfußträger 5 reicht. In die Fahrbahnplatte 14 können selbstverständlich
noch Längsarmierungen 16 mit eingebracht sein, die vor dem Ausbetonieren
einfach in die offene Struktur der Gitterträger eingeschoben und gegebenenfalls
mit diesen verbunden werden können. An die Schienenfußträger 5 sind zusätzlich
Kopfbolzen 17 angeschweißt, die eine bessere Einbindung in die Fahrbahnplatte
14 und damit eine besonders feste Verankerung dieser die Kräfte auf die Schiene
6 auffangenden Schienenfußträger bewerkstelligen. Zur Stabilisierung der
Schwellenbewehrung auf der Unterseite kann eine an die unteren Längsstangen
10 und 11 angeschweißte Mäanderschlange 18 dienen.The
Das Ausführungsbeispiel nach den Fig. 3 und 4 unterscheidet sich von dem nach
Fig. 1 im Wesentlichen dadurch, dass die beiden Gitterträger 7 und 8 durch im
Wesentlichen U-förmige Bügel 19, die an die Gitterträger 7 und 8 angeschweißt
sein können, miteinander verbunden sind, wobei die den Abstandhalter bildenden
Stahlplatten 4 in diesem Fall parallel zur Schwellenachse auf dem Basisschenkel
20 des U-Bügels 19 aufgeschweißt sind. Bei 17 erkennt man in den Fig. 3 und 4
wiederum zur Verankerung in der Fahrbahnplatte dienende am Schienenfußträger
5 befestigte, insbesondere angeschweißte, Kopfbolzen.The embodiment according to FIGS. 3 and 4 differs from that according to FIG
Fig. 1 essentially in that the two
Beim Ausführungsbeispiel nach den Fig. 5 und 6 sind die beiden nebeneinander
angeordneten Gitterträger 7 und 8 umgekehrt wie bei den Ausführungsbeispielen
nach den Fig. 1 bis 4 angeordnet, also die Spitze des dreieckigen Querschnitts
weist nach unten. Ansonsten hat man auch in diesem Fall wieder die als Abstandhalter
dienenden Stahlplatten 4 auf dem im Ausführungsbeispiel nach den Fig. 5
und 6 noch eine weiterer als Stahlkasten ausgebildeter Abstandhalter 21 angeordnet
ist, auf dem erst der Schienenfußträger 5 aufgeschweißt ist. Dieser kastenförmige
Abstandhalter 21 liegt wie gezeigt zur Gänze oder gegebenenfalls
auch nur teilweise oberhalb der Oberkante 15 der Fahrbahnplatte 14, was natürlich

arranged
Beim Ausführungsbeispiel nach den Fig. 7 und 8 besteht die Bewehrung 2 aus
zwei parallel nebeneinander angeordneten T-Profilträgern 22, die wiederum durch
die einen Abstandhalter bildenden Stahlplatten 4 miteinander verbunden sind. Neben
den Kopfbolzen 17 zur unmittelbaren festen Verankerung der Schienenfußträger
5 im Beton der Fahrbahnplatte 14, sind an der Unterseite der T-Profilträger
22 weitere Kopfbolzen 23 angeschweißt, die eine zusätzliche bessere Verankerung
der T-Träger in der Fahrbahnplatte bewirken. Um trotz des Vorsehens dieser
Kopfbolzen 23 einen Gleisrost aus Schwellen gemäß Fig. 7 und 8 vor dem Anheben
und Ausbetonieren auf der festen Unterlagsschicht 13 vorübergehend abstellen
zu können, sind als T-Trägerabschnitte ausgebildete Aufstellfüße 24 vorgesehen,
welche die Kopfbolzen 23 nach unten überragen.In the embodiment according to FIGS. 7 and 8, the

Das Ausführungsbeispiel nach den Fig. 12 bis 14, bei dem als Schwellenbewehrung
nur ein einziger durchgehender T-Träger 22' verwendet wird, ist zur Bildung
einer verbreiterten Auflagefläche im Bereich der Schienenbefestigungen jeweils
mit kurzen T-Profilträgern 25 versehen, die vorzugsweise mit dem Armierungs-T-Träger

lassen sich handelsübliche Lager 26 (siehe insbesondere Fig. 13) zwischen
der Schwellenarmierung und den Schienenfußträgern 5 verwenden.The embodiment of FIGS. 12 to 14, in which as threshold reinforcement
only a single continuous T-bar 22 'is used, is for formation
a widened bearing surface in the region of the rail fasteners in each case
provided with short T-
