- the double sliding threshold is firmly held together by the dovetail-shaped teeth of the respective rear walls, the manufacture of the individual elements is relatively complex and complex and there is a risk that the dovetail-shaped teeth will break out even in the event of a slight or weak vehicle impact, so that the entire double sliding threshold is destroyed in the impact area.
- the invention has for its object to provide a sleeper of the type mentioned, the half elements can be used on the one hand alone or on the other hand in the form of a double sleeper and are relatively easy to manufacture and their composition into a double sleeper by horizontal displacement of the half elements is possible.
- the half-elements are made from plate-shaped sections, that in each case the plate section of the half-element facing away from traffic runs perpendicularly, and that for connecting the rear walls of two half-elements lying against one another back to back by means of an eyelet / bolt connection the half-elements have tabs provided with bolt-receiving bores, which protrude from the half-element in the direction away from the carriageway, the tabs being provided with openings in opposite backs.
- the e.g. Half elements designed as hollow bodies can be used for a single sliding threshold or also for a double sliding threshold without any changes.
- spacers are arranged between the rear walls of half-elements arranged in two spaced rows as a double sliding threshold.
- the bottom walls of the half-elements protruding perpendicularly from the rear walls each consist of two spaced-apart plate sections; the bottom walls are preferably provided with sliding feet.
- the plate sections forming the upper sides of the half elements preferably run perpendicular to the rear walls.

- the back-to-back half-elements 2 and 3 are held together with a bolt / eyelet connection.
- the bolts have bent ends 24 so that they can be inserted through their brackets 25; however, they cannot slip through.
- Flanges 30, 32 are welded to the inner sides of the rear walls 4 and 5, which receive the bolts 20 or 21 in corresponding bores.
- the flanges 30 are fastened to the rear wall 4 and engage through slots 31 in the rear wall 5; the flanges 32 are fastened to the rear wall 5 and engage through slots 33 in the rear wall 4.

- the filler material or the housing is in the event of a vehicle impact, in particular a stronger vehicle impact understandably destroyed, while the composite back walls 50 and 51 act as a drawstring. If the two half-elements, which together form a double sliding threshold, are provided with sliding feet, the sliding threshold is displaced from its rest position in a more or less strong vehicle impact and bulges accordingly. Experiments have shown that bulges of up to 1.5 m are possible without the drawstring breaking.
- a single half element can also be used as a single sliding threshold, in which case the half element may need to be anchored to the ground or to the traffic area.
- two half-elements 70 and 71 are arranged at a distance from one another, with profile iron, tubular profiles or the like between these half-elements as spacers. Find use.
- These profile irons 72 and 73 are at their free ends by plates 74, 75 which in turn e.g. are connected by screw connections 76 to the respective rear wall 77 of the half element 71 or 78 of the half element 70.
- FIGS. 4 and 5 show two different possibilities of connecting the rear walls to one another.
- these two connection options differ in that, in the embodiment according to FIG. 4, the half elements are also directly connected to one another in the longitudinal direction of the sliding threshold, while in the embodiment according to FIG. 5 the individual half elements are only connected to the opposite half elements.
- the respective half-elements 2 and 3, as can be seen from FIGS. 4 and 5, are each firmly connected to one another with their rear walls 4 and 5 adjacent to one another.
- each rear wall has a slot and a tab in one plane, at least two such planes being provided on the half-elements.
- FIGS. 4 and 5 are the same with respect to the connection just described.
- tabs 80 and 81 are provided, which are also provided with holes and in a plane below or above the tabs 32 and 30 lie. These tabs connect the individual half elements directly in the longitudinal direction of the sliding threshold, so that not only the individual bolts and the corresponding tabs 30 and 32 are stressed in a vehicle impact, but also the tabs 80 and 81 cooperate.

Abstract
Description
Die Erfindung bezieht sich auf eine Gleitschwelle für Verkehrswege, welche aus quer zur Fahrtrichtung miteinander verbundenen, als Fertigteile hergestellte, auf die Fahrbahn aufgesetzten, jeweils als Gehäuse ausgebildeten gleich hohen Halbelementen besteht, deren Querschnitt jeweils einen Teilquerschnitt des Querschnitts einer aus zwei Reihen von Halbelementen erstellbaren Doppelgleitschwelle bildet.The invention relates to a sliding threshold for traffic routes, which consists of interconnected transverse to the direction of travel, manufactured as finished parts, placed on the carriageway, each designed as a housing half elements, the cross section of which is a partial cross section of the cross section of one of two rows of half elements Double sliding threshold forms.
Aus dem DE-GM 87 08 908 ist eine derartige Gleitschwelle bekannt. Die Rückwand der einzelnen Halbelemente ist jeweils mit einem schwalbenschwanzförmigen Profil versehen, so daß zwei Halbelemente - ggfs. versetzt zueinander von oben aus ineinander geschoben werden können. Es wird zwar ein fester Zusammenhalt der Doppelgleitschwelle durch die schwalbenschwanzförmige Verzahnung der jeweiligen Rückwände erreicht, es ist jedoch die Herstellung der einzelnen Elemente relativ aufwendig und kompliziert und es besteht die Gefahr, daß die schwalbenschwanzförmigen Zacken schon bei einem geringfügigen oder schwachen Fahrzeugaufprall ausbrechen, so daß die ganze Doppelgleitschwelle im Aufprallbereich zerstört wird.Such a sliding threshold is known from DE-GM 87 08 908. The rear wall of the individual half-elements is each provided with a dovetail-shaped profile, so that two half-elements can be pushed into one another from above, possibly offset from one another. Although the double sliding threshold is firmly held together by the dovetail-shaped teeth of the respective rear walls, the manufacture of the individual elements is relatively complex and complex and there is a risk that the dovetail-shaped teeth will break out even in the event of a slight or weak vehicle impact, so that the entire double sliding threshold is destroyed in the impact area.
Der Erfindung liegt die Aufgabe zugrunde, eine Gleitschwelle der eingangs erwähnten Art zu schaffen, deren Halbelemente einerseits allein oder anderseits auch in Form einer Doppelgleitschwelle benutzt werden können und relativ leicht herstellbar sind und deren Zusammensetzung zu einer Doppelgleitschwelle durch horizontales Verschieben der Halbelemente möglich ist.The invention has for its object to provide a sleeper of the type mentioned, the half elements can be used on the one hand alone or on the other hand in the form of a double sleeper and are relatively easy to manufacture and their composition into a double sleeper by horizontal displacement of the half elements is possible.
Die Aufgabe wird dadurch gelöst, daß erfindungsgemäß die Halbelemente aus plattenförmigen Abschnitten hergestellt sind, daß jeweils der dem Verkehr abgewandte, die Rückwand bildende Plattenabschnitt des Halbelements lotrecht verläuft und daß zum Verbinden der Rückwände zweier Rücken an Rücken aneinanderliegender Halbelemente mittels einer Ösen/Bolzen-Verbindung die Halbelemente mit die Bolzen aufnehmenden Bohrungen versehene Laschen aufweisen, die in fahrbahnabgekehrter Richtung vom Halbelement abstehen, wobei jeweils den Laschen zugeordnete Öffnungen in gegenüberliegenden Rücken vorgesehen sind. Die z.B. als Hohlkörper ausgebildeten Halbelemente lassen sich für eine Einzelgleitschwelle oder auch für eine Doppelgleit-Schwelle ohne jegliche Veränderungen verwenden.The object is achieved in that, according to the invention, the half-elements are made from plate-shaped sections, that in each case the plate section of the half-element facing away from traffic runs perpendicularly, and that for connecting the rear walls of two half-elements lying against one another back to back by means of an eyelet / bolt connection the half-elements have tabs provided with bolt-receiving bores, which protrude from the half-element in the direction away from the carriageway, the tabs being provided with openings in opposite backs. The e.g. Half elements designed as hollow bodies can be used for a single sliding threshold or also for a double sliding threshold without any changes.
Nach einer bevorzugten Ausführungsform der Erfindung sind zwischen den Rückwänden von in zwei beabstandeten Reihen als Doppelgleitschwelle angeordneten Halbelemente Abstandshalter angeordnet. Zweckmäßigerweise bestehen die von den Rückwänden senkrecht abstehenden Bodenwände der Halbelemente jeweils aus zwei beabstandeten Plattenabschnitten;
vorzugsweise sind die Bodenwände mit Gleitfüßen versehen.According to a preferred embodiment of the invention, spacers are arranged between the rear walls of half-elements arranged in two spaced rows as a double sliding threshold. Expediently, the bottom walls of the half-elements protruding perpendicularly from the rear walls each consist of two spaced-apart plate sections;
the bottom walls are preferably provided with sliding feet.
Die die oberen Seiten der Halbelemente bildenden Plattenabschnitte verlaufen vorzugsweise senkrecht zu den Rückwänden. Nach einer bevorzugten Ausführungsform der Erfindung steht vom Rand der von der Rückwand senkrecht abstehenden Bodenwand des Halbelements ein annähernd lotrecht angeordneter, streifenförmiger Plattenabschnitt als Abweisfläche beim Fahrzeugaufprall ab. Das Halbelement kann einen in ihm angeordneten Füllkörper tragen; dabei kann der Füllkörper aus einem Kunststoffgehäuse, ggfs. mit einem Füllstoff, z.B. Reifenrecyclingmaterial bestehen.The plate sections forming the upper sides of the half elements preferably run perpendicular to the rear walls. According to a preferred embodiment of the invention, an approximately vertically arranged, strip-shaped plate section protrudes from the edge of the bottom wall of the half-element projecting perpendicularly from the rear wall as a deflecting surface in the event of a vehicle impact. The half element can carry a packing element arranged in it; the filler can be made of a plastic housing, possibly with a filler, e.g. Tire recycling material exist.
Nach einer anderen Ausführungsform der Erfindung bestehen die Abschnitte aus Stahl. Schließlich ist es möglich, daß die Rückwände einerseits die Laschen tragen und andererseits Schlitze zum Durchstecken der Laschen aufweisen.According to another embodiment of the invention, the sections are made of steel. Finally, it is possible that the rear walls on the one hand carry the tabs and on the other hand have slots for pushing the tabs through.

Eine Doppelgleitschwelle 1 nach Fig. 1 besteht aus zwei spiegelbildgleich ausgebildeten Halbelementen 2, 3, die mit ihren jeweiligen Rückwänden 4 und 5 aneinander befestigt sind. Wie aus Fig. 4 und 5 ersichtlich ist, sind die jeweiligen Halbelemente jedoch so in bezug aufeinander versetzt miteinander verbunden, daß die in Querrichtung verlaufende Fugen 6 bzw. 7 zwischen den einzelnen Halbelementen in etwa auf der Hälfte des gegenüberliegenden Halbelemente verlaufen.A double sliding threshold 1 according to FIG. 1 consists of two
Auf diese Weise wird bei einer Verbindung der beiden Rückwände 4 und 5 - wie z.B. weiter unten näher beschrieben - ein Verbund geschaffen, der aus einzelnen Halbelementen zusammengesetzt ist, welche z.B. eine Höhe von ca. 50 cm und eine Fußbreite von 25 cm besitzen.In this way, when connecting the two
Es liegt auf der Hand, daß das Profil der Halbelemente beliebig sein kann. Im vorliegenden Fall ist von einem Profil ausgegangen, bei dem an eine lotrechte Abweisfläche im Bodenbereich 8 eine schräge Auffahrfläche 9 angeschlossen ist, wobei im Kronenbereich der Halbelemente wiederum eine beispielsweise 10 cm hohe lotrechte Abweisfläche 10 vorgesehen ist.It is obvious that the profile of the half elements can be arbitrary. In the present case, a profile is assumed in which an oblique drive-on
Bei der in Fig. 1 dargestellten Ausführungsform finden ca. 4 mm starke Stahlplatten Verwendung. Während es natürlich möglich ist, die jeweiligen Stirnseiten oder zumindest nur eine Stirnseite eines Halbelements mit einer dem gesamten Queschnitt des letzteren entsprechenden Stahlplatte abzuschließen, können - wie dargestellt - auch an ihren beiden Enden offene Halbelemente Verwendung finden, deren Bodenwand 11 aus zwei aufeinandergerichteten Flanschen besteht, so daß die Zugänglichkeit des Inneren der Halbelemente vom Boden aus gewährleistet ist. Die Rückwand 5 und der etwa 10 cm hohe lotrechte Abweisabschnitt 8 des Halbelementes kann durch zwei oder drei T-förmige Streben 12 ausgesteift werden.In the embodiment shown in FIG. 1, approximately 4 mm thick steel plates are used. While it is of course possible to close the respective end faces or at least only one end face of a half element with a steel plate corresponding to the entire cross section of the latter, open half elements can also be used at their two ends, the
Wie weiter unten näher beschrieben, werden die Rücken an Rücken anliegenden Halbelemente 2 und 3 mit einer Bolzen/Ösen-Verbindung zusammengehalten.As described in more detail below, the back-to-back half-
Die jeweiligen Bolzen 20 bzw. 21 erstrecken sich beispielsweise auf einer Höhe von 30 cm und sind durch Löcher oder Schlitze 22 in der Stirnwand 23 von oben in die Halbelemente einführbar. Die Bolzen weisen abgekröpfte Enden 24 auf, so daß sie durch ihre Halterungen 25 zwar durchgesteckt werden können; sie können jedoch nicht hindurchrutschen.The
Jeweils an den Innenseiten der Rückwände 4 und 5 sind Flansche 30,32 angeschweißt,die in entsprechenden Bohrungen die Bolzen 20 oder 21 aufnehmen. Die Flansche 30 sind an der Rückwand 4 befestigt und greifen durch Schlitze 31 in der Rückwand 5; die Flansche 32 sind an der Rückwand 5 befestigt und greifen durch Schlitze 33 in der Rückwand 4. Die Wirkungsweise der Flansche 80,81 wird weiter unten näher erläutert.
Bei der in Fig. 2 dargestellten Ausführungsform ist wieder von einer Doppelgleitschwelle mit spiegelbildgleichen Querschnitt ausgegangen worden.In the embodiment shown in FIG. 2, a double sliding threshold with a mirror-image-like cross-section has again been assumed.
Die Rückwände sind mit lotrecht von ihnen abstehenden Bodenwänden 56, 57 verbunden, die gegebenenfalls mit Gleitfüßen versehen sein können. Im unteren Bereich der Halbelemente sind wiederum von der Bodenwand 56 bzw. 57 senkrecht abstehende Abweisstreifen 58, 59 vorgesehen, die lotrecht verlaufen.The rear walls are connected to
In den Raum zwischen der Stirnwand 54 der Rückwand 51 der Bodenwand 56 und der Abweiswand 58 ist ein Füllkörper 60 eingesetzt.A
Dieser Füllkörper kann aus einem Kunststoffgehäuse bestehen, in welchem z.B. Reifenrecyclingmaterial enthalten ist. Auf der einen Seite kann, wie mit der strichierten Linie 61 angedeutet, der Querschnitt dieses Kunststoffgehäuses in etwa dem Querschnitt der Halbelemente 1 und 2 nach Fig.1 angepaßt sein, auf der anderen Seite ist auch eine Ausführungsform eines Querschnitts möglich, wie er mit der strichierten Linie 62 angedeutet ist.This filler body can consist of a plastic housing in which e.g. Tire recycling material is included. On the one hand, as indicated by the
Das Füllmaterial bzw. das Gehäuse wird bei einem Fahrzeugaufprall, insbesondere einem stärkeren Fahrzeugaufprall verständlicherweise zerstört, während die zusammengesetzten Rückenwände 50 und 51 gewissermaßen als Zugband wirken. Sollten die beiden Halbelemente, die zusammen eine Doppelgleitschwelle bilden, mit Gleitfüßen versehen sein, so wird bei einem mehr oder weniger starken Fahrzeugaufprall die Gleitschwelle aus ihrer Ruhestellung verschoben und beult sich entsprechend aus. Versuche haben gezeigt, daß Ausbeulungen bis zu 1,5 m möglich sind, ohne daß das Zugband reißt.The filler material or the housing is in the event of a vehicle impact, in particular a stronger vehicle impact understandably destroyed, while the
Es liegt auf der Hand, daß auch ein einzelnes Halbelement als Einzelgleitschwelle Verwendung finden kann, wobei in diesem Fall eine Verankerung des Halbelements mit dem Erdboden oder mit der Verkehrsfläche erforderlich sein dürfte.It is obvious that a single half element can also be used as a single sliding threshold, in which case the half element may need to be anchored to the ground or to the traffic area.
Nach Fig. 3 sind zwei Halbelemente 70 und 71 im Abstand voneinander angeordnet, wobei zwischen diesen Halbelementen als Abstandhalter Profileisen, rohrförmige Profile o.dgl. Verwendung finden. Diese Profileisen 72 und 73 sind an ihren freien Enden durch Platten 74, 75 die wiederum z.B. mit Schraubverbindungen 76 mit der jeweiligen Rückwand 77 des Halbelements 71 bzw. 78 des Halbelements 70 verbunden sind.According to Fig. 3, two half-
Auf die eben beschriebene Weise ist es erstmalig möglich, gleich ausgebildete Halbelemente,die jeweils eine Einzelgleitschwelle bilden, im Abstand voneinander anzuordnen, sei es als verschiebbare Doppelgleitschwelle oder sei es als mit dem Erdboden bzw. dem Verkehrsweg verankerte Doppelgleitschwelle.In the way just described, it is possible for the first time to arrange half-elements of the same design, each of which forms a single sliding threshold, at a distance from one another, either as a sliding double sliding threshold or as a double sliding threshold anchored to the ground or the traffic route.
Bei der eben beschriebenen Ausführungsform ist von einem in sich geschlossenen Hohlprofil - zusammengesetzt aus Stahlplatten - ausgegangen worden, wobei jeweils Profileisen 80 und 81 den etwa 10 cm hohen lotrechten Abweisbereich der Halbelemente aussteifen und abstützen.In the embodiment just described is composed of a self-contained hollow profile Steel plates - were started, with
Die in Fig. 4 und 5 dargestellten Längsschnitte durch eine Anzahl von fest miteinander verbundenen Halbelementen 2 bzw. 2 zeigen zwei unterschiedliche Verbindungsmöglichkeiten der Rückwände aneinander.The longitudinal sections shown in FIGS. 4 and 5 through a number of firmly connected
Grundsätzlich unterscheiden sich diese beiden Verbundmöglichkeiten dadurch, daß bei der Ausführungsform nach Fig. 4 auch die Halbelemente in Gleitschwellenlängsrichtung unmittelbar miteinander fest verbunden sind, während bei der Ausführungsform nach Fig. 5 eine Verbindung der einzelnen Halbelemente lediglich mit den gegenüberliegenden Halbelementen vorgenommen ist.Basically, these two connection options differ in that, in the embodiment according to FIG. 4, the half elements are also directly connected to one another in the longitudinal direction of the sliding threshold, while in the embodiment according to FIG. 5 the individual half elements are only connected to the opposite half elements.
Die jeweiligen Halbelemente 2 und 3 sind, wie aus Fig. 4 und 5 ersichtlich, jeweils versetzt zueinander mit ihren Rückwänden 4 und 5 aneinanderliegend miteinander fest verbunden.The respective half-
Während die an der Rückwand 4 verschweißten Laschen 30 durch die Schlitze 31 hindurchgesteckt sind, sind die Laschen 32, die an der Wand 5 angeschweißt sind, durch die Schlitze 33 in der Rückwand 4 hindurchgesteckt. Die Anordnung erfolgt wechselseitig, so daß jede Rückwand in einer Ebene einen Schlitz und eine Lasche aufweist, wobei mindestens zwei solcher Ebenen an den Halbelementen vorgesehen sind.While the
Die Ausführungsform nach Fig. 4 und 5 gleichen sich in bezug auf die eben beschriebene Verbindung.The embodiment of FIGS. 4 and 5 are the same with respect to the connection just described.
In Fig. 4 ist jedoch noch eine zusätzliche Verbindung in Längsrichtung der Gleitschwelle vorgesehen, wobei parallel zu den Rückwänden 4 und 5 Laschen 80 bzw. 81 vorgesehen sind, die ebenfalls mit Bohrungen versehen sind und in einer Ebene unterhalb bzw. oberhalb der Laschen 32 bzw. 30 liegen. Diese Laschen verbinden die einzelnen Halbelemente unmittelbar in Längsrichtung der Gleitschwelle, so daß bei einem Fahrzeugaufprall nicht nur die einzelnen Bolzen und die entsprechenden Laschen 30 und 32 beansprucht werden, sondern auch die Laschen 80 und 81 mitwirken.In Fig. 4, however, an additional connection is provided in the longitudinal direction of the sliding threshold, with parallel to the
