Abstract
Description
Die Erfindung bezieht sich auf eine Schwelle zum Anordnen auf einer im wesentlichen ebenen Unterlage, insbesondere bestimmt für eine feste Fahrbahn, vorzugsweise mit unterlagenseitig aufweisenden Ausnehmungen, die zumindest bereichsweise mit einer sowohl an der Unterlage als auch an der Schwelle haftenden oder sich mit diesen verbindenden Vergußmasse ausfüllbar sind, wobei die Schwelle über zumindest ein eine Aussparung der Schwelle durchsetzendes Spindelelement höhenverstellbar ist, das in einer die Schwelle von ihrer Oberseite bis zur Unterseite durchgehenden Aussparung verläuft, und eine in der Aussparung verdrehgesicherte Mutter oder gleichwirkendes Element umfaßt.The invention relates to a threshold for placing on a substantially flat base, in particular intended for a solid roadway, preferably with Document-side recesses, at least in some areas with a both adhering to or attaching to the base as well as to the threshold Potting compound can be filled, the threshold over at least one Recess of the threshold penetrating spindle element is adjustable in height one recess that runs through the threshold from the top to the bottom extends, and comprises a nut or equivalent element secured against rotation in the recess.
Ein Gleisoberbau mit Schienenschwellen und Schotter zeigt trotz vielfältiger Verbesserungen im Geschwindigkeitsbereich von zum Beispiel mehr als 200 km/h insbesondere technische Grenzen, so daß mehr und mehr auf die Konstruktion einer festen Fahrbahn mit stabilen steifen Schwellenlagerungen zurückgegriffen wird. Dabei wird die Schwelle wie Betonschwelle auf Asphalt- oder Betontragplatten oder in entsprechende Tröge eingebracht und sodann in einer Vergußmasse wie Beton oder Asphalt teilweise eingegossen. Eine Höhenjustierung kann dabei über innerhalb der Schwelle verlaufende Spindeln erfolgen. Um eine gute Verbindung mit der Vergußmasse zu erzielen, können die Schwellen sohlenseitig Ausnehmungen aufweisen. Hierdurch erfolgt auch eine Fixierung gegenüber horizontalen Beanspruchungen, insbesondere bei Kurvenfahrten (DE 34 29 413 A1).A track superstructure with rail sleepers and ballast shows despite various improvements in particular in the speed range of more than 200 km / h technical limits, so that more and more on the construction of a solid roadway with stable, stiff sleeper bearings. The Threshold like concrete threshold on asphalt or concrete slabs or in corresponding Troughs introduced and then partially in a casting compound such as concrete or asphalt poured. A height adjustment can be made within the threshold Spindles take place. To achieve a good connection with the sealing compound, you can the thresholds have recesses on the sole side. This also results in a Fixation against horizontal loads, especially when cornering (DE 34 29 413 A1).
Eine Schwelle der eingangs genannten Art ist der DE 40 37 849 Al zu entnehmen. Um die Schwelle höhenverstellbar auszubilden, erstreckt sich über die Höhe der Schwelle eine von einer Spindel durchsetzte Führungsbuchse, in der eine Gewindehülse verankert ist, zu der die Spindel drehbar ist. A threshold of the type mentioned can be found in DE 40 37 849 A1. Around The height of the threshold is adjustable and extends over the height of the threshold a guide bush penetrated by a spindle, in which a threaded sleeve is anchored to which the spindle is rotatable.
Um die Schwellen in Gleisrichtung insbesondere im Bereich einer Weiche zu fixieren, ist eine Bewehrung (Querbewehrung) vorgesehen, die aus üblichen Bewehrungseisen wie Rundstählen bestehen kann. Hierzu werden die Schwellen quer zu ihrer Längsrichtung durchbohrt, um anschließend die Bewehrung hindurchzuziehen. Sodann wird die Schwelle vergossen, wobei die Vergußmasse oberhalb der Bewehrung verlaufen muß.In order to fix the sleepers in the track direction, especially in the area of a switch, Reinforcement (transverse reinforcement) is provided, which consists of conventional reinforcing bars how round steels can exist. For this purpose, the sleepers are transverse to their longitudinal direction pierced to then pull the reinforcement through. Then will shed the threshold, with the sealing compound running above the reinforcement got to.
Durch diese Maßnahme wird die Bewehrung integraler Bestandteil der Schwelle, so daß ein Austausch dieser ohne Zerstören der Bewehrung nicht möglich ist. Um sicherzustellen, daß die Bohrungen zu einer unzulässigen Zerstörung der Schwelle selbst nicht führen, müssen diese in relativ großem Abstand zur Sohle eingebracht werden. Dies hat zur Folge, daß die Schwelle recht hoch eingegossen werden muß.With this measure, the reinforcement becomes an integral part of the threshold, so that an exchange of these is not possible without destroying the reinforcement. To ensure, that the bores to an inadmissible destruction of the threshold itself does not lead, these must be introduced at a relatively large distance from the sole. this has with the result that the threshold must be poured in quite high.
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Schwelle der eingangs genannten Art zur Verfügung zu stellen, die sicher auf der Unterlage befestigbar ist und problemlos Querkräfte aufnehmen kann. Auch zielt ein Teilaspekt der Erfindung auf eine einfache Montage bzw. Ausrichtung sowohl in horizontaler als auch in vertikaler Richtung ab. Ferner soll die Möglichkeit gegeben sein, mit einfachen Hilfsmitteln die Schwelle von der Unterlage wieder zu entfernen.The present invention is based on the problem of a threshold of the beginning to provide the type mentioned, which can be securely attached to the base and can easily absorb lateral forces. A partial aspect of the invention also targets easy assembly and alignment both horizontally and vertically Direction down. Furthermore, there should be the possibility of using simple aids Remove the threshold from the base.
Schließlich liegt der vorliegenden Erfindung das Problem zugrunde, eine Schwelle, insbesondere Betonschwelle bestimmt für eine feste Fahrbahn derart weiterzubilden, daß auf einfache Weise eine Bewehrung mehrerer aufeinanderfolgender Schwellen, insbesondere solche einer Weiche mit in Längsrichtung eines Gleises laufender Bewehrung erfolgen kann, ohne daß an der Schwelle eine möglicherweise zu einer Schwächung führende Bearbeitung notwendig ist. Auch soll gegebenenfalls ein Austausch einer Schwelle erfolgen können, ohne daß die Bewehrung selbst zerstört wird.Finally, the present invention addresses the problem of a threshold in particular to further develop concrete sleepers for a solid carriageway, that simple reinforcement of several successive sleepers, especially those of a switch with reinforcement running in the longitudinal direction of a track can take place without a possible weakening at the threshold leading processing is necessary. An exchange should also take place if necessary a threshold can occur without the reinforcement itself being destroyed.
Das Problem wird erfindungsgemäß im wesentlichen dadurch gelöst, daß die von dem Spindelelement durchsetzte Aussparung über eine Stufe übergehend einen oberen und einen unteren Abschnitt unterschiedlicher Querschnitte umfasst, daß sich zumindest bereichsweise in dem unteren Abschnitt eine erste Hülse des Spindelementes erstreckt, die mit einem auf der Unterlage sich abstützenden Element verbunden ist und von der eine sich zumindest bereichsweise in den oberen Abschnitt erstreckende, drehbar zu der ersten Hülse ausgebildete zweite Hülse ausgeht, die in die an der Stufe abgestützte verdrehgesicherte Mutter oder ein gleichwirkendes Element eingreift.According to the invention, the problem is essentially solved in that the Spindle element passes through an upper and a recess a lower section of different cross-sections that at least partially a first sleeve of the locker element extends in the lower section, which is connected to an element supported on the base and from which an at least partially extending in the upper section, rotatable to the trained first sleeve formed second sleeve, which in the supported on the step secured against rotation Mother engages or an equivalent element.
Durch Drehen der oberen Hülse kann folglich die Schwelle angehoben bzw. abgesenkt werden, so daß eine vertikale Ausrichtung möglich ist.The threshold can consequently be raised or lowered by turning the upper sleeve be so that vertical alignment is possible.
Durch diese Maßnahme ist der weiteren sichergestellt, daß ein problemloses Lösen der Schwelle auch dann erfolgen kann, wenn die Ausnehmungen untergossen sind; denn beim Drehen der zweiten Hülse und ein damit einhergehendes Anheben der Schwelle erfolgt ein automatisches Abheben dieser von der Unterlage wie Fahrbahn.This measure further ensures that problem-free solving of the Threshold can also occur if the recesses are cast under; because when turning the second sleeve and an associated raising of the threshold this is automatically lifted off the surface like the road.
Vorzugsweise umfasst das Spindelement eine sich auf der Unterlage abstützende Platte, die in einer Auskammerung der Schwelle angeordnet und von Wandungen der Auskammerung umfangsseitig umgeben ist. Durch diese Maßnahme ist sichergestellt, daß beim Untergießen der Schwelle Vergußmaterial nicht in die Auskammerung gelangen kann.The locker element preferably comprises a support that is supported on the base Plate arranged in a cavity of the threshold and from walls of the Chamber is surrounded on the circumference. This measure ensures that when pouring the threshold potting material not in the chamber can reach.
Um auch bei angehobener Schwelle sicherzusteilen, daß in die Auskammerung Vergußmasse nicht gelangen kann, sieht eine Weiterbildung der Erfindung vor, daß die Platte einen umlaufenden sich in die Auskammerung erstreckenden Rand aufweist, wobei die Höhe des Randes zumindest gleich dem maximalen durch das Spindelelement ermöglichenden Hub ist.In order to ensure, even when the threshold is raised, that potting compound is in the chamber a further development of the invention provides that the Plate has a peripheral edge extending into the cavity, wherein the height of the edge is at least equal to the maximum through the spindle element enabling stroke.
Die Spindelplatte weist vorzugsweise eine Rechteckform auf, so daß folglich die die Auskammerung begrenzenden Wandungen ebenfalls eine Rechteckform bilden.The spindle plate preferably has a rectangular shape, so that consequently the Walls delimiting the chamber also form a rectangular shape.
Das Problem wird auch durch eine Schwelle dadurch gelöst, daß aufeinanderfolgende Schwellen über eine in Gleisrichtung verlaufende von den Schwellen ausgehende Bewehrung in Form von vorzugsweise Bewehrungseisen wie Rundstählen verbindbar sind, wobei die Bewehrung unterhalb der Schwelle verlaufend von von der Schwelle ausgehenden Befestigungselementen gehalten ist.The problem is also solved by a threshold that successive Thresholds over a track extending from the sleepers Reinforcement in the form of preferably reinforcing bars such as round steel can be connected are, with the reinforcement below the threshold extending from the threshold outgoing fasteners is held.
Abweichend vom vorbekannten Stand der Technik verläuft die Bewehrung nicht innerhalb der Schwelle, sondern unterhalb von dieser, so daß nach Fertigstellung der Schwelle Bohrungen oder ähnliches nicht erforderlich sind. Dadurch, daß die Bewehrung sohlenseitig verläuft, ist ein Eingießen der Schwelle losgelöst von der Bewehrung nur in dem Umfang erforderlich, daß das erforderliche Fixieren gewährleistet ist.In contrast to the prior art, the reinforcement does not run within the threshold, but below this, so that after completion of the Threshold bores or the like are not required. In that the reinforcement running on the sole side, the threshold is cast in separately from the reinforcement only necessary to the extent that the required fixing is guaranteed.
Insbesondere ist die Bewehrung lösbar mit dem Befestigungselement verbunden, so daß folglich ein Austausch einer Schwelle möglich ist, ohne daß die Bewehrung beschädigt wird.In particular, the reinforcement is detachably connected to the fastener, so that consequently, a threshold can be exchanged without damaging the reinforcement becomes.
Nach einer bevorzugten Ausführungsform geht die Befestigung von einem Plattenelement aus, das auf der Unterlage abstützbar ist, über die die Schwelle zur Unterlage justierbar ist. Durch diese Maßnahmen verläuft die Bewehrung im definierten Abstand zur Unterlage.According to a preferred embodiment, the attachment starts from a plate element from which can be supported on the base, via which the threshold to the base is adjustable. With these measures, the reinforcement runs at a defined distance to the pad.
Zur Lagefixierung der Bewehrung kann das Plattenelement auf seiner der Schweile zugewandten Seite Aufnahmen in Form von offenen Lagern oder geschlossenen Bügeln aufweisen. Ersteres beitet die Möglichkeit, daß auch ein nachträgliches Befestigen der Bewehnung wie Rundstahl auf dem Plattenelement möglich ist.To fix the reinforcement in position, the plate element on its side facing the weld can Side recordings in the form of open bearings or closed brackets exhibit. The former offers the possibility that a subsequent attachment of the Reinforcement of how round steel is possible on the plate element.
Auch bietet diese Ausführungsform den Vorteil, daß die Schwelle ausgetauscht werden kann, ohne daß das Plattenelement und die von disem ausgehende Bewehrung entfernt werden müssen.This embodiment also has the advantage that the threshold can be replaced can without removing the plate element and the reinforcement emanating from it Need to become.
Ein Lösungsvorschlag sieht vor, daß das Befestigungselement von einem die Schwelle durchsetzenden Schraub- oder Spindelelemenent ausgeht und zur Sohle der Schwelle abstandsveränderbar ist. A proposed solution provides that the fastener from one of the threshold penetrating screw or spindle element and to the bottom of the threshold distance is variable.
Bei einer Schwelle in Form einer Betonschwelle mit in Längsrichtung verlaufenden Bewehrungseisen ist vorgesehen, daß das Befestigungselement in der Schwelle verankert ist und vorzugsweise von einem Bewehrungseisen ausgeht. Dabei kann das Befestigungselement eine hülsenartige bzw. klammerartig wirkende Aufnahme für die aufeinanderfolgende Schwellen verbindende Bewehrung aufweisen.With a sleeper in the form of a concrete sleeper with lengthways Reinforcing iron is provided that the fastener is anchored in the threshold and is preferably based on a rebar. The fastener can a sleeve-like or clip-like receptacle for the successive Have reinforcement connecting thresholds.
Bei einer weiteren Ausführungsform geht von vorzugsweise in einer parallel zur Schwellenunterseite sich erstreckenden Ebene verlaufenden Bewehrungseisen ein U-förmiger Bügel mit parallel oder in etwa parallel zur Schwellenunterseite verlaufenden Seitenschenkelabschnitten als Befestigung für die Bewehrung aus, die mit den Seitenschenkelabschnitten in einer Art verbunden werden können, wie diese aus der Bewehrungstechnik bekannt ist.In a further embodiment, preferably in a parallel to Reinforcing iron extending underneath the plane extending a U-shaped plane Stirrups with parallel or approximately parallel to the underside of the threshold Side leg sections as a fastening for the reinforcement made with the side leg sections can be connected in a way like this from reinforcement technology is known.
Auch kann die Befestigung ein U-förmiges Blechelement sein, dessen Querschenkel sich entlang einer innerhalb der Schwelle angeordneten Mutter einer Verschraubung wie Durchsteckverschraubung erstreckt und dessen Seitenschenkel die Schwelle sohlenseitig durchsetzen und Durchbrechungen für die Bewehrung aufweisen. Nach diesem Vorschlag wird die zum Befestigen einer Rippenplatte oder eines Gleitstuhls bereits vorhandene Durchsteckverschraubung benutzt, um als Verankerung für die Befestigung der Bewehrung zu dienen. The attachment can also be a U-shaped sheet metal element, the cross leg of which along a nut of a screw connection arranged inside the threshold such as Push-through fitting extends and the side leg of the threshold on the sole side enforce and have openings for the reinforcement. According to this suggestion becomes the one already available for attaching a ribbed plate or a sliding chair Push-through fitting used to anchor the attachment of the To serve reinforcement.

In den Fig. 1 bis 9, in denen grundsätzlich gleiche Elemente mit gleichen Bezugszeichen versehen sind, sind Längs- bzw. Querschnitte von Betonschwellen (10) dargestellt, die für eine feste Fahrbahn bestimmt sind. Dabei sind die den Figuren 1, 3 und 9 zu entnehmende Betonschwellen (10) in einem Betontrog (12) mit Füllbeton (14) eingegossen. Andere Möglichkeiten der Lagefixierung der Betonschwelle (10) sind gleichfalls gegeben. So kann die Betonschwelle (10) zum Beispiel auf Betonplatten aufliegen.1 to 9, in which basically the same elements are provided with the same reference numerals, longitudinal or cross sections of concrete sleepers (10) are shown, which are intended for a solid roadway. The concrete sleepers (10) shown in FIGS. 1, 3 and 9 are cast in a concrete trough (12) with filler concrete (14). Other possibilities for fixing the position of the concrete sleeper (10) are also given. For example, the concrete sleeper (10) can be used on concrete slabs lie on.
Unabhängig davon kann die Betonschwelle (10) über ein Spindelelement (16) zu einer Unterlage, die nicht dargestellt ist, höhenverstellt werden.Regardless of this, the concrete sleeper (10) can be made into a via a spindle element (16) Pad, which is not shown, can be adjusted in height.
Ferner weist die Betonschwelle (10) unterseitig eine Strukturierung auf, die mit dem Füllbeton (14) oder einem anderen Gießmaterial ausgefüllt wird, um einen Formschluß sicherzustellen, der ein Verrücken der Schwelle (10) bei auf diese einwirkenden Querkräften ausschließt.Furthermore, the concrete sleeper (10) has a structuring on the underside which corresponds to the Filling concrete (14) or other pouring material is filled to a positive fit ensure that the threshold (10) moves when there are transverse forces acting on it excludes.
Die Betonschwelle (10) weist in ihrer Längsrichtung verlaufende Bewehrungseisen auf, die beispielhaft mit den Bezugszeichen (18) und (20) versehen sind.The concrete sleeper (10) has reinforcing bars running in its longitudinal direction, which are provided with the reference numerals (18) and (20) by way of example.
Um aufeinanderfolgende Betonschwellen (10) insbesondere im Bereich einer Weiche zueinander zu fixieren, verläuft in Längsrichtung der von den Betonschwellen (10) aufgenommenen Schienen (22) eine Bewehrung (Querbewehrung), die aus bekannten Bewehrungseisen wie Rundstählen besteht. Um die Bewehrung auf einfache Weise mit den Betonschwellen (10) zu verbinden, ohne daß diese nachbearbeitet werden müssen und ohne daß die Betonschwelle (10) im nicht gewünschten Umfang eingegossen werden muß, ist erfindungsgemäß vorgesehen, daß die Bewehrung unterhalb der Schwelle (10), also entlang ihrer Sohle (24) in nachstehend beschriebener Weise verläuft, wobei gegebenenfalls eine lösbare Verbindund vorgesehen ist. Hierdurch ergibt sich der Vorteil, daß ein Austausch bzw. Erneuern von Betonschwellen (10) möglich ist, ohne daß die Bewehrung selbst zerstört werden muß.Around successive concrete sleepers (10), particularly in the area of a switch to fix to each other runs in the longitudinal direction of the concrete sleepers (10) recorded rails (22) a reinforcement (transverse reinforcement), which from known Reinforcing bars such as round steel exist. To easily use the reinforcement to connect the concrete sleepers (10) without having to be reworked and without the concrete sleeper (10) being poured in to an undesired extent must be provided according to the invention that the reinforcement below the Threshold (10), that is along its sole (24) in the manner described below runs, with a detachable connection and possibly being provided. This gives the advantage that an exchange or renewal of concrete sleepers (10) is possible, without the reinforcement itself having to be destroyed.
Nach dem Ausführungsbeispiel der Fig. 1 und 2 erfolgt eine Befestigung einer durch einen Rundstab (26) gebildeten Bewehrung mittels eines Bügels (28), der in die Betonschwelle (10) eingegossen wird. Hierzu wird der Bügel (28) auf zwei Rundstählen (18), (20) der Längsbewehrung der Betonschwelle (10) gelegt, die in einer Ebene verlaufen, die sich parallel zur Sohle (24) erstreckt. According to the embodiment of FIGS. 1 and 2, a through is attached a round bar (26) formed reinforcement by means of a bracket (28) in the concrete sleeper (10) is poured. For this purpose, the bracket (28) is placed on two round steels (18), (20) the longitudinal reinforcement of the concrete sleeper (10), which run in one plane, which extends parallel to the sole (24).
Der U-förmige Bügel (28) weist parallel zur Sohle (24) verlaufende Seitenschenkelendabschnitte (32) und (34) auf, die quer zur Längsrichtung der Betonschwelle (10) verlaufen und mit dem Rundstahl (26) in gewohnter Weise wie zum Beispiel durch Schweißen oder mit Draht verbunden werden.The U-shaped bracket (28) has side leg end sections running parallel to the sole (24) (32) and (34), which are transverse to the longitudinal direction of the concrete sleeper (10) run and with the round steel (26) in the usual way such as through Welding or connecting with wire.
Nach dem Ausführungsbeispiel der Fig. 3 sind abweichende Befestigungen für ebenfalls vorzugsweise aus Rundeisen bestehende Bewehrungen (36) und (38) vorgesehen.According to the embodiment of FIG. 3, different attachments are also for Reinforcements (36) and (38) preferably made of round bars are provided.
Die Bewehrungen (36) sind auf einer Platte (40) befestigt, die Teil des Spindelelementes (16) ist. Das Spindelelement (16) zur Höhenjustierung der Betonschwelle (10) durchsetzt eine Aussparung (42) in der Betonschwelle (10) und umfaßt einen zylindrischen oberen Abschnitt (44) und einen zylindrischen unteren Abschnitt (46). Der untere Abschnitt (46) ist in seinem Durchschnitt größer als der obere Abschnitt (44), so daß zwischen diesen eine Stufe (48) verläuft. Von der Platte (40) geht eine Hülse (50) aus, die sich bis in den unteren Abschnitt (46) durch die Aussparung (42) erstreckt.The reinforcements (36) are attached to a plate (40), which is part of the spindle element (16) is. The spindle element (16) for height adjustment of the concrete sleeper (10) passes through a recess (42) in the concrete sleeper (10) and comprises a cylindrical upper section (44) and a cylindrical lower section (46). Of the lower section (46) is larger on average than the upper section (44), so that a step (48) runs between them. A sleeve (50) goes from the plate (40) from which extends into the lower section (46) through the recess (42).
Innerhalb des oberen Abschnitts (44) der Durchbrechung (42) erstreckt sich eine weitere Hülse (52), die sich einerseits auf der unteren Hülse (50) abstützt und andererseits ein Außengewinde aufweist, auf das eine Mutter (54) geschraubt ist, die im unteren Abschnitt (46) der Durchbrechung (42) angeordnet ist, wobei auf der Mutter (54) bzw. auf einer auf dieser vorhandenen Scheibe die Stufe (48) aufliegt. Ferner ist die Mutter (54) verdrehgesichert, so daß beim Drehen der oberen Hülse (52), die beabstandet zur Oberseite der Schwelle (10) endet, ein Anheben bzw. Absenken dieser erfolgt. Um die Hülse (53) drehen zu können, sind diametral zueinander angeordnete Einkerbungen (56) vorhanden.Another extends within the upper section (44) of the opening (42) Sleeve (52), which is supported on the one hand on the lower sleeve (50) and on the other Has external thread, on which a nut (54) is screwed, the lower section (46) of the opening (42) is arranged, on the nut (54) or on a step (48) rests on this existing disc. Furthermore, the mother (54) secured against rotation, so that when rotating the upper sleeve (52) which is spaced from Top of the threshold (10) ends, this is raised or lowered. To the To be able to turn the sleeve (53) are notches (56) arranged diametrically to one another available.
Damit nach dem Justieren einerseits ein unkontrolliertes Verstellen der oberen Hülse (52) ausgeschlossen und andererseits die Schwelle (10) selbst verankert wird, ist ein Bolzen bzw. eine Schraube (58) vorhanden, der die obere Hülse (52) durchsetzt und mit seinem Außengewinde und einem in der Innenwandung der unteren Hülse (50) eingelassenen Innengewinde zusammenwirkt. Durch den Bolzen (58) erfolgt eine kraftschlüssige Verbindung zwischen der Schwelle (10) und der Eingießmasse über die eingegossene Stülzplatte (60) bzw. die Bewehrung (74). Der Kopf des Bolzens (58) liegt nach seinem Anziehen auf der Schwelle (10) und verschließt gleichzeitig die Durchbrechung (42).So that after the adjustment, on the one hand, an uncontrolled adjustment of the upper sleeve (52) excluded and on the other hand the threshold (10) itself is anchored Bolts or a screw (58) available, which passes through the upper sleeve (52) and with its external thread and one embedded in the inner wall of the lower sleeve (50) Internal thread interacts. The bolt (58) provides a positive connection Connection between the threshold (10) and the pouring compound via the cast Backing plate (60) or the reinforcement (74). The head of the bolt (58) lies after his Tighten on the threshold (10) and at the same time closes the opening (42).
Auf der der Betonschwelle (10) zugewandten Seite der Platte (40) sind quer zur Längsrichtung der Betonschwelle (10) U-förmige Bügel (60), (62) befestigt, die zusammen mit der Platte (40) rohr- oder hülsenförmige Aufnahmen (64), (66) für die Querbewehrungen (36) bilden.On the side of the plate (40) facing the concrete sleeper (10) are transverse to the longitudinal direction the concrete sleeper (10) U-shaped bracket (60), (62) attached together with the plate (40) tubular or sleeve-shaped receptacles (64), (66) for the transverse reinforcements (36) form.
Entsprechende Aufnahmen (64) und (66) sind auch für die Bewehrungen (38) vorgesehen. Eine hierzu erforderliche Platte (68) ist jedoch nicht Teil eines Spindelelementes, sondern allein mit Hilfe eines Bolzens (70) zur Betonschwelle (10) lagefixiert. Dabei wird vorzugsweise der Bolzen (10) in einem Umfang angezogen, daß die Oberseiten der U-förmigen Elemente (60) und (62) unterseitig an der Betonschwelle (10) anliegen. Um ein entsprechendes Verstellen zu ermöglichen, geht von der Platte (68) eine Hülse (72) mit Innengewinde aus, in die der Bolzen (70) eingreift.Corresponding receptacles (64) and (66) are also provided for the reinforcements (38). However, a plate (68) required for this is not part of a spindle element, but only fixed in position with the aid of a bolt (70) to the concrete sleeper (10). The bolt (10) is preferably tightened to such an extent that the upper sides of the U-shaped elements (60) and (62) on the underside of the concrete sleeper (10) issue.

Abweichend von dem Ausführungsbeispiel der Fig. 3 und 5 können Bewehrungen (106) und (108) auch auf zur Betonschwelle (10) hin offene Lager (107) und (109) gelegt werden, um durch Anziehen der Platte (68) mittels des Bolzens (70) die Bewehrungen (106) und (108) zwischen der Unterseite der Betonplatte (10) und den U-förmigen Lagern (107) und (109) festzuklemmen.In contrast to the exemplary embodiment in FIGS. 3 and 5, reinforcements (106) and (108) also placed on bearings (107) and (109) open towards the concrete sleeper (10) the reinforcements by tightening the plate (68) by means of the bolt (70) (106) and (108) between the underside of the concrete slab (10) and the U-shaped ones Clamp bearings (107) and (109).
Anhand der Fig. 10 bis 12 sollen noch einmal wesentliche Merkmale einer für eine feste Fahrbahn bestimmten Schwelle (110) erläutert werden. Auch wird erneut auf das eine Höhenverstellung der Schwelle (110) ermöglichendes wie bereits im Zusammenhang mit den Fig. 3 und 4 beschriebenes Spindelelement eingegangen werden.With the help of FIGS. 10 to 12, essential features are once again intended for one fixed roadway certain threshold (110) are explained. Also on the again a height adjustment of the threshold (110) enables as already in connection 3 and 4 spindle element described.
Der Fig. 10 ist eine Seitenansicht und teilweise im Schnitt der vorzugsweise aus Beton bestehenden Schwelle (110) zu entnehmen, die im Ausführungsbeispiel aus zwei Abschnitten (112) und (114) besteht, die starr über eine Platte (116) miteinander verbunden sind.Fig. 10 is a side view and partly in section, which is preferably made of concrete existing threshold (110), which in the exemplary embodiment consists of two sections (112) and (114), which are rigidly connected to one another via a plate (116) are.
Die Schwelle (110) liegt auf einer befestigten Fläche als Unterlage (118) wie Asphaltdecke oder einer oder mehrerer Betonplatten auf. Die Schwelle (110) weist im Bereich außerhalb nachstehend beschriebener und den Fig. 3 und Fig. 4 entsprechende Spindelelemente (120), (122) und (124), (126) senkrecht zur Längsrichtung der Schwelle (110) verlaufende Rippen auf, von denen zwei rein beispielhaft mit den Bezugszeichen (128) und (130) versehen sind. Sofern die Schwelle (110) eine Betonschwelle ist, handelt es sich bei den Rippen (128) und (130) um Aufbetonierungen.The threshold (110) lies on a paved surface as a base (118) such as an asphalt surface or one or more concrete slabs. The threshold (110) points in the area outside of the spindle elements described below and corresponding to FIGS. 3 and 4 (120), (122) and (124), (126) perpendicular to the longitudinal direction of the threshold (110) running ribs, two of which are purely exemplary with the reference numerals (128) and (130) are provided.
