Abstract

A joint bridging arrangement comprises a bridging unit having a central portion, side parts, and anchoring units adjoining the longitudinal sides of the side parts. The side parts are pivotably connected to the central portion for movement about a pivot axis parallel to the longitudinal axis of the bridging arrangement. Cleats or legs of the side part and anchoring unit are interengaged and relatively slidable at an acute angle relative to the upper side of the center part. The upper-most surface of the bridging unit includes a portion having a wedge shaped cross section corresponding to the acute angle so that the transition from the bridging to the anchoring units, and hence to the structural parts bridged by the joint is essentially stepless.

Description

Die Erfindung betrifft eine Fugenüberbrückungsvorrichtung aus einer Überbrückungseinheit und zwei an deren Längsseiten angeschlossenen Verankerungseinheiten. Letztere sind jeweils auf ihrer der Überbrückungseinheit zugewandten Längsseite mit einer seitlich offenen Nut versehen, worin die Überbrückungseinheit eingreift.The invention relates to a joint bridging device comprising a bridging unit and two anchoring units connected on the long sides thereof. The latter are each provided on their longitudinal side facing the bridging unit with a laterally open groove, in which the bridging unit engages.

Bei einer derartigen, aus der DE-A-35 29 877 bekannten Vorrichtung besteht die Überbrückungseinheit aus zwei in senkrechter Richtung zur Fugenlängserstreckung teleskopartig ineinanderschiebbaren Überbrückungsteilen, von denen das eine, im Querschnitt stimmgabelförmig ausgebildete Teil das andere, im Querschnitt rechteckförmig ausgebildete Teil zwischen seinen Schenkeln aufnimmt. Die einander abgewandten äußeren Randstreifen der Überbrückungsteile sind zylinderförmig gestaltet und lagern in entsprechend halbschalenförmig ausgebildeten Nuten der Verankerungseinheiten.In such a device known from DE-A-35 29 877, the bridging unit consists of two bridging parts which can be telescopically pushed into one another in the vertical direction to the longitudinal extent of the joint, one of which has a part with a tuning fork-shaped cross-section and the other part with a rectangular cross-section between its legs records. The outer edge strips of the bridging parts facing away from one another are cylindrical in shape and are supported in correspondingly half-shell-shaped grooves in the anchoring units.

Mit der bekanten Vorrichtung kann nicht nur die Überbrückung einer sich in der Breite verändernden Fuge zwischen zwei Bauwerksteilen aufrechterhalten werden, sondern auch ein Niveauausgleich erfolgen, wenn sich die beispielsweise einen Boden bildenden Bauwerksteile relativ zueinander in vertikaler Richtung verlagern. Während nämlich die Verankerungseinheiten an den Fugenlängsrändern mit den jeweiligen Bauwerksteilen starr verbunden sind, ist der Überbrückungseinheit eine Schwenkbewegung um die Mittelachse der durch die Nuten gebildeten Lagerschalen in den Verankerungseinheiten ermöglicht, wenn die Bauwerksteile ihr Niveau relativ zueinander verändern. Dadurch ist ein im wesentlichen fließender Übergang von der Oberfläche eines Bauwerksteils zu der eines anderen erreichbar. Bei einer Veränderung der Fugenbreite wird die Überbrückung dadurch aufrechterhalten, daß die Überbrückungsteile mehr oder weniger tief teleskopartig in Eingriff bleiben.With the known device, not only can the bridging of a joint which changes in width be maintained between two building parts, but also a level compensation can take place if the building parts, for example forming a floor, are displaced in the vertical direction relative to one another. While the anchoring units are rigidly connected to the respective structural parts at the longitudinal edges of the joints, the bridging unit is one Pivoting movement around the central axis of the bearing shells formed by the grooves in the anchoring units is made possible when the structural parts change their level relative to one another. This enables an essentially smooth transition from the surface of one part of the building to that of another. When the joint width is changed, the bridging is maintained in that the bridging parts remain more or less deeply telescopically engaged.

In Abhängigkeit von der Querschnittsstärke der Überbrückungsteile entsteht zwangsläufig eine mehr oder weniger ausgeprägte Stufe im Bereich des Übergangs von einem Bauwerksteil zum anderen. Um die in jedem Falle störende Höhe einer derartigen Stufe möglichst gering zu halten, ist es aus der DE-A-30 15 011 bekannt, bei einer derartigen Vorrichtung die Querschnittsstärken der Überbrückungsteile kleiner zu halten, als es das aus den Belastungen zu erwartende Biegemoment erfordert. Damit der Einsatz der Vorrichtung in hochbelasteten Bereichen, wie in Böden von Lagerhallen, Supermärkten und anderen, mit durch entsprechende Radlasten von Gabelstaplern und dergleichen beanspruchten Bodenflächen nicht zu einer Verformung der Überbrückungsteile führt, ist bei der bekannten Vorrichtung an einem der Fugenlängsränder eine Stützschiene fest eingespannt, durch die wenigstens ein Überbrückungsteil unterfangen wird. Um Veränderungen der Fugenbreite zu berücksichtigen, kann die Stützschiene nur mit einem Längsrandstreifen fest eingespannt werden und darf sich nur über die zu erwartende minimale Fugenbreite erstrecken. Die somit seitlich frei vorragende Stützschiene muß mit zunehmender Fugenbreite eine erhöhte Belastung aufnehmen, die sich aus der Lasteintragung im von der Einspannseite entferntesten Bereich ergibt. Das daraus resultierende Biegemoment erfordert nicht nur eine Stützschiene mit einem entsprechend großen Widerstandsmoment, sondern auch Einspannmittel, die den zu erwartenden Hebelkräften standhalten.Depending on the cross-sectional thickness of the bridging parts, a more or less pronounced step inevitably arises in the area of the transition from one building part to the other. In order to keep the height of such a step, which is disruptive in any case, as low as possible, it is known from DE-A-30 15 011 to keep the cross-sectional thicknesses of the bridging parts smaller in such a device than the bending moment to be expected from the loads requires . So that the use of the device in highly stressed areas, such as in the floors of warehouses, supermarkets and others, with floor surfaces claimed by corresponding wheel loads of forklifts and the like does not lead to deformation of the bridging parts, a support rail is firmly clamped in one of the longitudinal edges of the joint in the known device , by which at least one bridging part is underpinned. In order to take changes in the joint width into account, the support rail can only be firmly clamped with a longitudinal edge strip and may only extend over the expected minimum joint width. The support rail, which projects freely to the side, must absorb an increased load with increasing joint width, which results from the load entry in the area furthest from the clamping side. The resulting bending moment not only requires a support rail with a correspondingly large section modulus, but also clamping devices that can withstand the expected lever forces.

Bei einer aus der DE-A-31 51 516 bekannten Überbrückungsvorrichtung sind die Überbrückungsteile durch eine Stützschiene stabilisiert, die beidseitig mit jeweils einem Längsrandstreifen in eine Nut eingeschoben ist, welche in den Überbrückungsteilen selbst vorgesehen ist. Federn, die zu beiden Seiten zwischen der Stützschiene und dem Boden der Nuten eingespannt sind, halten die Stützschiene unabhängig vom Breitenzustand der Fuge stets in Fugenmitte. Während die Überbrückungsteile mit Unterseiten auf der Stützschiene aufliegen, bildet die Oberseite der Überbrückungsteile eine gemeinsame Tangente zu ihren beiden in den Lagerschalen gehaltenen zylinderförmigen Randstreifen. Da schließlich die Überbrückungsteile im Bereich ihrer ineinandergreifenden Randstreifen einen im Grundriß mäanderförmigen Kantenverlauf aufweisen und so kongruent ausgebildet sind, daß mit Zähnen des einen Überbrückungsteils Zahnlücken des anderen Überbrückungsteils mehr oder weniger ausfüllbar sind, lassen sich auch durchgehende Stufen im Übergangsbereich der Überbrückungsteile vermeiden. Statt dessen entstehen jedoch je nach Breitenzustand der Fuge mehr oder weniger große Durchbrüche entsprechend den nicht durch Zähne ausgefüllten Teilen der Zahnlücken. Dadurch kann in diese Konstruktion Wasser und Schmutz eindringen, womit die Haltbarkeit und die Funktionsfähigkeit erheblich beeinträchtigt werden. Eine Abdichtung der Konstruktion läßt sich jedoch nur mit einem erheblichen zusätzlichen Aufwand erreichen, wobei die Abdichtungsebene nur unterhalb der ineinandergreifenden Überbrückungsteile vorgesehen werden kann, so daß diese selbst auch bei aufwendigen Abdichtungsmaßnahmen weiterhin ungeschützt bleiben müssen.In a bridging device known from DE-A-31 51 516, the bridging parts are stabilized by a support rail which is inserted on both sides with a longitudinal edge strip into a groove which is provided in the bridging parts themselves. Springs that are clamped on both sides between the support rail and the bottom of the grooves always hold the support rail in the center of the joint, regardless of the width of the joint. While the bridging parts rest with their undersides on the support rail, the top of the bridging parts forms a common tangent to their two cylindrical edge strips held in the bearing shells. Finally, since the bridging parts in the area of their interlocking edge strips have a meandering edge profile in the outline and are designed to be congruent so that teeth of one bridging part can fill gaps in the other bridging part more or less, continuous steps in the transition region of the bridging parts can also be avoided. Instead, however, arise depending on the latitude the joint more or less large openings corresponding to the parts of the tooth gaps not filled by teeth. This allows water and dirt to penetrate into this construction, which significantly affects durability and functionality. Sealing of the construction can, however, only be achieved with considerable additional effort, the sealing level being able to be provided only below the interlocking bridging parts, so that they must remain unprotected even with complex sealing measures.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art so auszubilden, daß mit ihr nicht nur über eine Fuge hinweg ein weitgehend stufenloser fließender Übergang von einer Bauwerksfläche zur anderen erreichbar ist, sondern dazu auch auf ein aufwendiges Unterstützungssystem für die Überbrückungseinheit verzichtet werden kann und insbesondere auch bei keinem Breitenzustand der Fugen Durchbrüche entstehen, so daß mit der Vorrichtung ebenso eine wirksame Abdichtung erzielbar ist.The invention has for its object to provide a device of the type described in such a way that not only can a largely smooth transition from one building surface to another be reached across a joint, but also a complex support system for the bridging unit can be dispensed with breakthroughs can occur, especially when the joints are not wide, so that an effective seal can also be achieved with the device.

Zur Lösung dieser Aufgabe wird von einer Fugenüberbrückungsvorrichtung der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.To achieve this object, a joint bridging device of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in the characterizing part of the same.

Nach der erfindungsgemäßen Ausbildung ist die dreiteilige Überbrückungseinheit in sich gelenkig, während die Verankerungseinheiten mit Nuten versehen sind, worin die Seitenteile der Überbrückungseinheit mit Leisten als Federn eingreifen. Dabei ergibt sich die Möglichkeit, die oberen, überlagernden Leisten der Überbrückungs- bzw. der Verankerungseinheiten verhältnismäßig dünn und die überlagerten Leisten der Überbrückungseinheit bzw. der Verankerungseinheiten in einer für die zu erwartende Kraftübertragung ausreichenden Stärke zu dimensionieren, da die gesamte Kraftübertragung von der Überbrückungseinheit auf die beiden Verankerungseinheiten über die letztgenannten Leisten erfolgt. Da weiterhin erfindungsgemäß die den Breitseiten der Leisten zugewandten Laibungsseiten der Nuten eben oder konkav bzw. konvex ausgebildet sind und im wesentlichen in einem spitzen Winkel zur Oberseite des Mittelteils der Überbrückungseinheit verlaufen, ist die Voraussetzung dafür geschaffen, die oberen Leisten der Überbrückungseinheit bzw. der Verankerungseinheiten mit einem entsprechend der Neigung der Laibungsseiten nach außen bzw. innen hin keilförmig abnehmenden Querschnitt auszuführen. Dadurch kann die Stärke der oberen Leisten sogar auf Null auslaufen und ihre Oberseite sich somit stufenlos an die Oberseiten der Verankerungseinheiten bzw. an die der Seitenteile der Überbrückungseinheit anschließen. Es genügt dazu, daß die jeweilige Unterseite der oberen Leisten der Überbrückungseinheit bzw. der Verankerungseinheiten ebenso in einem spitzen Winkel verläuft wie die ihr zugewandte und sie aufnehmende betreffende Oberseite der oberen Leisten der Verankerungseinheiten bzw. die Oberseite der entsprechenden Leisten der Überbrückungseinheit.According to the embodiment of the invention, the three-part bridging unit is articulated in itself, while the anchoring units are provided with grooves, in which the side parts of the bridging unit engage with strips as springs. This results in the possibility of dimensioning the upper, superimposed strips of the bridging or anchoring units relatively thinly and the superimposed strips of the bridging unit or anchoring units in a thickness sufficient for the expected power transmission, since the entire power transmission from the bridging unit the two anchoring units are carried out via the last mentioned last. According to the invention, since the reveal sides of the grooves facing the broad sides of the strips are flat or concave or convex and essentially run at an acute angle to the upper side of the central part of the bridging unit, the prerequisite is created for the upper strips of the bridging unit or the anchoring units with a cross-section that decreases in a wedge-shaped manner outwards or inwards in accordance with the inclination of the reveal sides. As a result, the thickness of the upper strips can even run to zero and their upper side can thus be connected continuously to the upper sides of the anchoring units or to the side parts of the bridging unit. It is sufficient for the respective underside of the upper strips of the bridging unit or the anchoring units to run at an acute angle as well as the top side of the upper strips of the anchoring units facing them and receiving them Top of the corresponding bars of the bridging unit.

Es versteht sich, daß es zweckmäßig ist, die Randkanten der oberen Leisten der Überbrückungseinheit bzw. die entsprechenden Leisten der Verankerungseinheiten nicht nach Art einer Messerschneide auszubilden, sondern über einen kleinen Radius abzurunden, wodurch noch keine gravierende Störung im fließenden Übergang entsteht.It goes without saying that it is expedient not to design the edge edges of the upper strips of the bridging unit or the corresponding strips of the anchoring units in the manner of a knife edge, but rather to round them off over a small radius, as a result of which no serious disturbance in the flowing transition arises.

Für die Stabilität der erfindungsgemäßen Konstruktion ist jedenfalls kein über die Fugenbreite reichendes Unterstützungselement erforderlich. Weiterhin lassen sich Durchbrüche in der Überbrückungseinheit vermeiden, so daß mit der Überbrückungsvorrichtung insgesamt auch eine dichte Fugenabdeckung erzielbar ist.In any case, no support element extending over the joint width is required for the stability of the construction according to the invention. Furthermore, breakthroughs in the bridging unit can be avoided, so that overall a tight joint covering can also be achieved with the bridging device.

Nach einer Ausgestaltung der Erfindung weist die Verankerungseinheit ein im Querschnitt etwa U-förmiges Anchlußprofil mit zur Vorrichtungsmitte hin konvergierend geneigten Schenkeln auf, von denen der untere, eine Auflage für die Seitenteile der Überbrückugseinheit bildende Schenkel länger ist als der obere, in eine Nut des Seitenteils der Überbrückungseinheit hineinragende Schenkel.According to one embodiment of the invention, the anchoring unit has a cross-section approximately U-shaped connecting profile with legs that converge towards the center of the device, of which the lower leg, which forms a support for the side parts of the bridging unit, is longer than the upper leg, into a groove in the side part legs protruding into the bridging unit.

Vorzugsweise umfassen die Lagerschalen die zylinderförmigen Randstreifen des Mittelteils um mehr als 180°, so daß ein selbsttätiges Lösen des Mittelteils von den Randstreifen in senkrechter Richtung zur Längserstreckung der Konstruktion ausgeschlossen ist, wenn sich zudem die Zylinderform der Randstreifen über vorzugsweise etwa 270° erstreckt. Da dadurch das Mittelteil auf seiner Unterseite noch nicht zu sehr eingekerbt wird, verbleibt gleichwohl ein völlig ausreichend bemessener Schwenkbereich für die Einzelteile der Überbrückungseinheit, womit selbst extrem große Setzbewegungen von Bauwerksteilen berücksichtigt werden können.The bearing shells preferably encompass the cylindrical edge strips of the central part by more than 180 °, so that automatic detachment of the central part from the edge strips in a direction perpendicular to the longitudinal extent of the construction is excluded if the cylindrical shape also changes the edge strip preferably extends over approximately 270 °. Since this means that the middle part is not yet indented too much on its underside, there remains a completely sufficiently dimensioned swivel range for the individual parts of the bridging unit, with which even extremely large setting movements of structural parts can be taken into account.

Wenn die Fugenlaibungen statt in Form von schiefen Ebenen in einem großen Radius bogenförmig verlaufen, wobei der jeweils tiefste bzw. höchste Punkt des Bogens vorzugsweise senkrecht unterhalb der Mittelachse der Lagerschalen liegt, welche die Seitenteile bilden, läßt sich bei einer Veränderung der Fugenbreite die Niveauveränderung der Oberfläche der Überbrückungseinheit noch stärker reduzieren als bei völlig eben ausgerichteten Fugenlaibungen, die in einem spitzen Winkel zur Horizontalen verlaufen.If the joint reveals are curved in a large radius instead of in the form of inclined planes, with the deepest or highest point of the arch preferably lying perpendicularly below the central axis of the bearing shells, which form the side parts, the level change of the joint width can be changed when the joint width is changed Reduce the surface of the bridging unit even more than with completely flush joint reveals that run at an acute angle to the horizontal.

Um alle Einzelteile der Vorrichtung in senkrechter Richtung zur Längserstreckung untrennbar miteinander zu verbinden, sieht eine weitere Ausgestaltung der Erfindung vor, daß die Breite des Öffnungsquerschnitts der Nuten in der Überbrückungseinheit und den Verankerungseinheiten kleiner ist als die Querschnittsbreite der Nuten im übrigen, wozu im Bereich des Öffnungsquerschnitts der Nuten am jeweiligen Rand der Leiste der Verankerungseinheiten und am jeweiligen Rand der Leiste der Überbrückungseinheit gegeneinander gerichtete Nasen angeformt sind.In order to inseparably connect all of the individual parts of the device in the vertical direction to the longitudinal extent, a further embodiment of the invention provides that the width of the opening cross section of the grooves in the bridging unit and the anchoring units is smaller than the cross-sectional width of the grooves in the rest, which in the area of Opening cross-section of the grooves on the respective edge of the bar of the anchoring units and on the respective edge of the bar of the bridging unit are directed against each other.

Diese Ausgestaltung stellt auch sicher, daß bei einem etwaigen Verklemmen der Überbrückungseinheit mit einer der beiden Verankerungseinheiten dieser Zustand nicht dazu führt, daß die Überbrückungseinheit mit zunehmender Fugenbreite ihre Verbindung mit der anderen Verankerungseinheit verliert.This configuration also ensures that if the bridging unit becomes jammed with one of the two anchoring units, this condition does not result in the bridging unit losing its connection with the other anchoring unit with increasing joint width.

Nach einer weiteren Ausgestaltung der Erfindung besteht jede Verankerungseinheit aus einem mit einem winkelförmigen Basisprofil ergänzten Anschlußprofil, wobei das Basisprofil einen als Fußstück ausgebildeten horizontalen Schenkel aufweist, worauf in parallelem Abstand voneinander zwei vertikal ausgerichtete Schenkel angeordnet sind, die formschlüssig und senkrecht zu ihrer Längserstreckung zudem kraftschlüssig in hinterschnittene Aussparungen der unteren leisten des Anschlußprofils eingreifen.According to a further embodiment of the invention, each anchoring unit consists of a connection profile supplemented with an angular base profile, the base profile having a horizontal leg designed as a foot piece, whereupon two vertically aligned legs are arranged at a parallel distance from one another, which are also positively and perpendicular to their longitudinal extension engage in undercut recesses in the lower strips of the connection profile.

Durch diese Ausgestaltung läßt sich ein einheitlich ausgebildetes Anschlußprofil verwenden, das mit verschiedenen Basisprofilen kombinierbar ist, die sich insbesondere durch ihre unterschiedliche Schenkelhöhe unterscheiden, um somit beispielsweise an verschiedene Bodenbelagsstärken angepaßt zu werden. Die Anordnung von zwei vertikal ausgerichteten Schenkeln auf dem Fußstück des Basisprofils führt zu einer stabilen Positionierung des Anschlußprofils, das dadurch auch einer Kippbelastung standhalten kann.With this configuration, a uniformly designed connection profile can be used, which can be combined with different base profiles, which differ in particular by their different leg heights, in order to be adapted, for example, to different floor covering thicknesses. The arrangement of two vertically aligned legs on the base of the base profile leads to a stable positioning of the connection profile, which can also withstand a tipping load.

Schließlich ist nach einer weiteren Ausgestaltung jedes Anschlußprofil aus zwei lösbar miteinander verbundenen, je einen Schenkel bildenden Leisten zusammengesetzt.Finally, according to a further embodiment, each connection profile is composed of two strips, each detachably connected and forming a leg.

Durch diese Ausgestaltung lassen sich die jeweils den unteren Schenkel des Anschlußprofils bildenden Profilteile vorweg entlang den zu überdeckenden Fugen an den Bauwerksteilen montieren und daran beispielsweise durch Schraubverbindungen die den zweiten Schenkel bildenden Profilteile zusammen mit der Überbrückungseinheit anbringen, so daß die Vervollständigung der Vorrichtung zu einem möglichst späten Zeitpunkt nach entsprechendem Baufortschritt erfolgen kann.With this configuration, the respective profile parts forming the lower leg of the connecting profile can be mounted beforehand along the joints to be covered on the building parts and attached to them, for example by screw connections, the profile parts forming the second leg together with the bridging unit, so that the device is completed as much as possible can take place late after appropriate construction progress.

In der Zeichnung sind verschiedene Ausführungsbeispiele einer erfindungsgemäßen Überbrückungsvorrichtung jeweils in einem Querschnitt dargestellt:Various exemplary embodiments of a bridging device according to the invention are each shown in a cross section in the drawing:

Fig. 1 zeigt eine Vorrichtung mit einer Überbrückungseinheit 1, die aus einem im Querschnitt etwa rechteckförmigen Mittelteil 2 und zwei an dessen Längsseiten gelenkig angeschlossenen Seitenteilen 3 zusammengesetzt ist. Dazu sind zwei Randstreifen 4 des Mittelteils 2 zylinderförmig ausgebildet und in entsprechend ausgebildeten Lagerschalen 5 der Seitenteile 3 gehalten.1 shows a device with a bridging unit 1, which is composed of a central part 2 which is approximately rectangular in cross section and two side parts 3 which are articulated on the longitudinal sides thereof. For this purpose, two edge strips 4 of the middle part 2 are cylindrical and are held in correspondingly formed bearing shells 5 of the side parts 3.

Zusätzlich zu einer Lagerschale 5 ist in jedem Seitenteil 3 eine Nut 6 vorgesehen, deren im spitzen Winkel geneigt zur Vorrichtungsmitte verlaufende Laibungen durch Leisten 7 und 8 definiert sind. Während die jeweils obere Leiste 7 im Querschnitt nach außen keilförmig abnimmt, ist die jeweils untere Leiste 8 mit einer nach oben weisenden, den Öffnungsquerschnitt der Nut 6 einengenden Nase 9 versehen.In addition to a bearing shell 5, a groove 6 is provided in each side part 3, the soffits, which are inclined at an acute angle to the center of the device, are defined by strips 7 and 8. While the respective upper bar 7 decreases in a wedge shape in cross-section, the respective lower bar 8 is provided with an upwardly pointing nose 9, which narrows the opening cross section of the groove 6.

Jedes Seitenteil 3 der Überbrückungseinheit 1 greift mit seiner Leiste 8 in eine Nut 10 einer Verankerungseinheit 11. Die Laibungen der Nut 10 sind durch Leisten 12 und 13 definiert. Während die jeweils obere Leiste 12 mit einer nach unten weisenden, den Querschnitt der Nut 10 einengenden Nase 14 versehen ist, erstreckt sich die jeweils untere Leiste 13 in ihrer Breite zu beiden Seiten über die Breite der Leiste 8 des jeweiligen Seitenteils 3 und bietet eine schiefe, zur Vorrichtungsmitte hin geneigte Auflage- und Gleitebene für die Überbrückungseinheit 1.Each side part 3 of the bridging unit 1 engages with its strip 8 in a groove 10 of an anchoring unit 11. The reveals of the groove 10 are defined by strips 12 and 13. While the respective upper bar 12 is provided with a downward-pointing nose 14 which narrows the cross section of the groove 10, the respective lower bar 13 extends in width on both sides across the width of the bar 8 of the respective side part 3 and offers an oblique one , support and sliding plane inclined towards the center of the device for the bridging unit 1.

Verändert sich die Breite einer durch die Vorrichtung abgedeckten Fuge 15 zwischen zwei Bauwerksteilen 16 oder verändert eines der Bauwerksteile 16 gegenüber dem anderen sein Niveau, bleibt gleichwohl in beiden Fällen ohne Stufenbildung ein fließender Übergang von einer Bauwerksoberfläche 16′ zur anderen erhalten.If the width of a joint 15 covered by the device changes between two building parts 16 or if one of the building parts 16 changes its level compared to the other, in both cases a smooth transition from one building surface 16 'to the other remains in both cases.

Fig. 2 zeigt eine Vorrichtung, die sich gegenüber der in Fig. 1 dargestellten in zwei Bereichen unterscheidet:FIG. 2 shows a device which differs from the one shown in FIG. 1 in two areas:

Zum einen ist jede Verankerungseinheit 11 nicht einstückig ausgebildet, sondern aus lösbar miteinander verbundenen Leisten 12 und 13 zusammengesetzt, wozu Senkkopfschrauben 17 über die Vorrichtungslänge verteilt in entsprechende Bohrungen jeder Leiste 12 eingelassen und in Gewindebohrungen der Leisten 13 eingedreht sind.On the one hand, each anchoring unit 11 is not formed in one piece, but is instead composed of strips 12 and 13 which are detachably connected to one another, for which purpose countersunk screws 17, distributed over the length of the device, are inserted into corresponding bores in each strip 12 and are screwed into threaded bores in the strips 13.

Zum andern veranschaulicht die links dargestellte, mit einem Schraubenbolzen 18 am betreffenden Bauwerksteil 16 befestigte Verankerungseinheit 11 und das betreffende Seitenteil 3 der Überbrückungseinheit 1, daß die Laibungen der Nuten 6 und 10 in großen Radien R₁ bis R₄ um einen Mittelpunkt M konvex bzw. konkav geformt verlaufen können, wobei der Mittelpunkt M in einer zur Oberseite der Vorrichtung senkrechten Ebene liegt, die durch die Mittelachse der zugehörigen Lagerschale 5 läuft.On the other hand, it illustrates the one shown on the left, with a screw bolt 18 on the relevant structural part 16 attached anchoring unit 11 and the relevant side part 3 of the bridging unit 1 that the reveals of the grooves 6 and 10 in large radii R₁ to R₄ around a center point M can be convex or concave, the center point M in a plane perpendicular to the top of the device lies, which runs through the central axis of the associated bearing shell 5.

Schließlich sind auch noch in stirnseitigen Bohrungen der Leisten 13 Preßstifte 19 eingetrieben, mit denen sich Teillängen der Vorrichtung in an sich bekannter Weise fluchtend aneinanderschließen lassen.Finally, 13 press pins 19 are also driven into the front-side bores of the strips, with which partial lengths of the device can be aligned in a manner known per se.

Fig. 3 zeigt eine Vorrichtung mit einer Überbrückungseinheit gemäß Fig. 1, wobei jede Verankerungseinheit 11 um ein Basisprofil 20 ergänzt ist, das jeweils aus einem Fußstück 21 und darauf angeordneten, unterschiedlich hoch reichenden, vertikal ausgerichteten Schenkeln 22, 23 besteht, die formschlüssig in Nuten des unteren Schenkels 13 der jeweiligen Verankerungseinheit 11 eingreifen.Fig. 3 shows a device with a bridging unit according to Fig. 1, wherein each anchoring unit 11 is supplemented by a base profile 20, each of which consists of a foot piece 21 and vertically oriented legs 22, 23 arranged thereon, which reach different heights and which form-fit in Engage grooves of the lower leg 13 of the respective anchoring unit 11.

Fig. 4 zeigt in vergrößertem Maßstab eine linke Hälfte der Vorrichtung gemäß Fig. 1, wobei sowohl im zylinderförmigen Randstreifen 4 des Mittelteils 2 der Überbrückungseinheit 1 wie auch in der oberen Leiste 12 der Verankerungseinheit 11 eine elastische Dichtungsschnur 24 bzw. 25 eingelassen ist, welche zwischen diesen Teilen und der Lagerschale 5 bzw. der Leiste 7 eine Abdichtung herstellt, so daß sich die Vorrichtung in einer wasserdichten Ausführungsform präsentiert.Fig. 4 shows on an enlarged scale a left half of the device according to Fig. 1, wherein an elastic sealing cord 24 and 25 is embedded both in the cylindrical edge strip 4 of the central part 2 of the bridging unit 1 and in the upper bar 12 of the anchoring unit 11 creates a seal between these parts and the bearing shell 5 or the strip 7, so that the device presents itself in a watertight embodiment.

Fig. 5 zeigt in vergrößertem Maßstab die linke Hälfte der Vorrichtung, wie sie im wesentlichen in Fig. 2 als rechte Hälfte dargestellt ist, wobei die gleichen Abdichtungsvorkehrungen, wie in Fig. 4 dargestellt, getroffen sind. Fig. 5 verdeutlicht insbesondere, daß die Senkkopfschrauben 17 zur Verbindung der Leisten 12 und 13 in einer Linie mit den Schraubenbolzen 18 zur Befestigung der Verankerungseinheiten 11 an den Bauwerksteilen 16 angeordnet sein können.Fig. 5 shows on an enlarged scale the left half of the device, as it is shown essentially in Fig. 2 as the right half, the same sealing arrangements as shown in Fig. 4 have been taken. 5 illustrates in particular that the countersunk screws 17 for connecting the strips 12 and 13 can be arranged in a line with the screw bolts 18 for fastening the anchoring units 11 to the structural parts 16.

Im Ausführungsbeispiel gemäß Fig. 6 sind die beiden Seitenteile 3 der Überbrückungseinheit 1 jeweils mit nur einer Leiste 8 versehen, die in eine Nut 10 der Verankerungseinheit 11 eingreift. Die Laibungen der Nut 10 und ebenso die Seitenflächen der Leiste 8 verlaufen in großen konkaven bzw. konvexen Bögen um einen Mittelpunkt M, wobei dieser in einer zur Oberseite der Vorrichtung senkrechten Ebene liegt, die durch die Mittelachse der zugehörigen Lagerschale 5 verläuft, jedoch entsprechend tief unterhalb des Niveaus der Bauwerksoberfläche 16′ liegt. Um den gleichen Mittelpunkt M ist auch eine konvexe Tragfläche der Leiste 13 der Verankerungseinheit 11 gebogen, worauf eine entsprechend konkav gebogene Fläche des Seitenteils 3 der Überbrückungseinheit 1 aufliegt. Die Leiste 12 jeder Verankerungseinheit 11 nimmt im Querschnitt zur Fugenmitte hin etwa keilförmig ab, so daß mit der Leiste 12 ebenso ein stufenloser Übergang bewerkstelligt wird wie in den Ausführungsbeispielen der Fig. 1 bis 5 mit der Leiste 7 der Seitenteile 3.In the exemplary embodiment according to FIG. 6, the two side parts 3 of the bridging unit 1 are each provided with only one strip 8, which engages in a groove 10 of the anchoring unit 11. The soffits of the groove 10 and also the side surfaces of the strip 8 run in large concave or convex arcs around a center point M, which lies in a plane perpendicular to the upper side of the device, which runs through the central axis of the associated bearing shell 5, but correspondingly deep is below the level of the building surface 16 '. A convex supporting surface of the strip 13 of the anchoring unit 11 is also bent around the same center point M, on which a correspondingly concavely curved surface of the side part 3 of the bridging unit 1 rests. The strip 12 of each anchoring unit 11 decreases approximately wedge-shaped in cross-section towards the center of the joint, so that the strip 12 also achieves a continuous transition as in the exemplary embodiments in FIGS. 1 to 5 with the strip 7 of the side parts 3.

Das Ausführungsbeispiel gemäß Fig. 7 unterscheidet sich vom Ausführungsbeispiel der Fig. 6 im wesentlichen dadurch, daß die Verankerungseinheiten 11 jeweils aus zwei durch Schrauben 17 lösbar miteinander verbundenen Leisten 12 und 13 zusammengesetzt sind. Dazu befindet sich in den Leisten 13 jeweils eine hinterschnittene Nut 26, worin hammerkopfförmige Muttern 27 zur Aufnahme der Schrauben 17 eingeschoben sind.The embodiment of FIG. 7 differs from the embodiment of FIG. 6 essentially in that the anchoring units 11 are each composed of two strips 12 and 13 releasably connected by screws 17. For this purpose, there is in each case an undercut groove 26 in the strips 13, in which hammer-head-shaped nuts 27 for inserting the screws 17 are inserted.

In allen Ausführungsbeispielen gleiten Tragteile der Überbrückungseinheit 1 auf zur Vorrichtungsmitte hin geneigten bzw. ansteigenden und im Bedarfsfall mit einer Beschichtung versehenen Auflageflächen der Verankerungseinheiten 11, wodurch bei jeder Fugenbreite die Oberseite der Vorrichtung ohne Stufenbildung in die Bauwerksoberfläche der durch die Fuge 15 getrennten Bauwerksteile 16 übergeht.In all of the exemplary embodiments, supporting parts of the bridging unit 1 slide onto support surfaces of the anchoring units 11 which are inclined or rising towards the center of the device and, if necessary, provided with a coating, as a result of which the top of the device merges into the building surface of the building parts 16 separated by the joint 15 at each joint width without step formation .
