Description

Die Erfindung betrifft eine Vorrichtung zum Überbrücken von Dehn- und Bewegungsfugen in einem Bauwerksboden und besteht aus zwei Verankerungseinheiten und einer Überbrückungseinheit. Die Überbrückungseinheit ist an ihren Längsrändern gelenkig mit jeweils einer Verankerungseinheit verbunden und durch zwei ineinandergreifende Brückenglieder gebildet. Von den Brückengliedern greift das eine patrizenförmig ausgebildete Brückenglied mit einer Feder in eine Nut des anderen entsprechend matrizenförmig ausgebildeten Brückengliedes je nach dem Breitenzustand der Fuge mehr oder weniger tief ein.The invention relates to a device for bridging expansion and movement joints in a building floor and consists of two anchoring units and a bridging unit. The bridging unit is articulated at its longitudinal edges to an anchoring unit and is formed by two interlocking bridge members. Of the bridge members, one of the male bridge members with a spring engages more or less deeply in a groove of the other corresponding male link member, depending on the width of the joint.

Eine derartige Vorrichtung ist aus der DE-PS 35 29 877 bekannt, wobei die Überbrückungseinheit aus zwei in senkrechter Richtung zur Fugenlängserstreckung und horizontal teleskopartig ineinanderschiebbaren Überbrückungsgliedern besteht, von denen das eine im Querschnitt stimmgabelförmig ausgebildete Glied das andere im Querschnitt rechteckförmig ausgebildete Glied zwischen seinen Schenkeln aufnimmt. Die voneinander abgewandten äußeren Randstreifen der Brückenglieder sind zylinderförmig gestaltet und lagern gelenkig in entsprechend schalenförmig ausgebildeten Nuten der Verankerungseinheiten.Such a device is known from DE-PS 35 29 877, wherein the bridging unit consists of two bridging members which can be telescopically pushed into one another in the vertical direction to the longitudinal extension of the joint and horizontally telescopically, one of which has a section with a tuning fork-shaped cross-section and the other with a cross-sectionally rectangular section between its legs records. The outer edge strips of the bridge members facing away from one another are cylindrical in shape and are articulated in correspondingly shell-shaped grooves in the anchoring units.

Mit der bekannten 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 den Bauwerksboden bildenden Teile relatiy 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. Bei einer Veränderung der Fugenbreite wird die Überbrückung dadurch aufrechterhalten, daß die beiden die Überbrückungseinheit bildenden Brückenglieder mehr oder weniger tief teleskopartig in Eingriff bleiben.With the known device, not only can the bridging of a joint of varying width between two structural parts be maintained, but also a level compensation if the parts forming the building floor move relative to each other in the vertical direction. While the anchoring units are rigidly connected to the respective structural parts on the longitudinal edges of the joint, the bridging unit is capable of pivoting movement about the central axis of the bearing shells formed by the grooves in the anchoring units when the structural parts change their level relative to one another. When the width of the joint is changed, the bridging is maintained in that the two bridge members forming the bridging unit remain more or less telescopically engaged.

In Abhängigkeit von der Querschnittsstärke der Brückenglieder entsteht bei der bekannten Vorrichtung zwangsläufig eine mehr oder weniger tiefe offene Rinne insbesondere zwischen der Stirnseite eines oberen Schenkels des stimmgabelförmigen Überbrückungsgliedes und der dieser Stirnseite gegenüberliegenden Seite eines oberen Randstreifens der Verankerungseinheit. Je nach Breitenzustand der Fuge erfährt die Rinne zudem eine mehr oder weniger große Verbreiterung.Depending on the cross-sectional thickness of the bridge members, a more or less deep open channel inevitably arises in the known device, in particular between the front side of an upper leg of the tuning fork-shaped bridging member and the side of an upper edge strip of the anchoring unit opposite this front side. Depending on the width of the joint, the channel also widened to a greater or lesser extent.

Es ist nicht nur aufwendig, die Rinnen bei der bekannten Vorrichtung ständig sauberzuhalten, um die Funktionsfähigkeit der Vorrichtung nicht zu beeinträchtigen, sondern auch nachteilig, daß durch die Rinnen eine stoßfreie Befahrbarkeit eines mit derartigen Überbrückungsvorrichtungen ausgestatteten Bodens vereitelt ist. Fahrzeugrollen können je nach ihrem Außendurchmesser in die Rinnen einsinken und die Gleichförmigkeit der Fahrbewegung erheblich stören. Die dabei auftretenden Stoßbelastungen können zu Beschädigungen sowohl an den Fahrzeugen wie auch an den die Fugen abdeckenden Vorrichtungen führen. Es kann sich aber auch die Unfallgefahr beim Begehen der so ausgerüsteten Böden erhöhen, da in den Rinnen Schuhabsätze festklemmbar sind. Ganz allgemein verursachen die Rinnen mangels eines fließenden Übergangs Stolperstellen.It is not only expensive to keep the channels in the known device constantly clean so as not to impair the functionality of the device, but also disadvantageous in that the channels prevent a bump-free accessibility of a floor equipped with such bridging devices. Vehicle roles can vary depending on their Sink the outer diameter into the gutters and significantly disrupt the uniformity of the movement. The resulting shock loads can damage both the vehicles and the devices covering the joints. However, the risk of accidents when walking on the floors equipped in this way can also increase, since shoe heels can be clamped in the channels. In general, the channels cause stumbling points due to the lack of a smooth transition.

Der Erfindung liegt die Aufgabe zugrunde, eine stabile Vorrichtung zum Überbrücken von Dehn- und Bewegungsfugen aus zwei Verankerungseinheiten und einer nur aus zwei Gliedern bestehenden Überbrückungseinheit zu schaffen, bei der auch entsprechend kräftig dimensionierte Glieder der Überbrückungseinheit einen über Fugen hinweg durchgehenden fließenden Übergang von einem Bauwerksteil zu einem anderen ermöglichen.The invention has for its object to provide a stable device for bridging expansion and movement joints from two anchoring units and a bridging unit consisting of only two members, in which also appropriately dimensioned members of the bridging unit a seamless transition from one part of the building across joints allow to another.

Zur Lösung dieser Aufgabe wird von einer Vorrichtung 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 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.

Durch die erfindungsgemäße Neigung der Nut und Feder in einem spitzen Winkel zur Ebene des Bauwerksboden kann nicht nur der untere Schenkel des matrizenförmigen Brückenglieds, sondern auch der die Nut abdeckende Schenkel von seinem freien Ende aus zunehmend stärker ausgebildet sein und dadurch dem Biegemomentverlauf angepaßt werden. Am freien Ende kann die Schenkelstärke dagegen so sehr reduziert sein, daß die Oberseite des die Nut abdeckenden Schenkels ohne eine ausgeprägte Stufenbildung in die Oberseite der Feder übergeht. Je größer der Neigungswinkel der Nut und Feder gewählt wird, um so kräftiger lassen sich die Schenkel des matrizenförmigen Brückenglieds keilförmig ausbilden, wobei ein durchgehender, nahezu völlig niveaugleicher fließender Übergang von einem Bauwerksteil zum anderen gewährleistet bleibt.Due to the inclination of the tongue and groove according to the invention at an acute angle to the level of the building floor, not only the lower leg of the matrix-shaped bridge member, but also the leg covering the groove can become increasingly stronger from its free end be formed and thereby be adapted to the bending moment curve. At the free end, on the other hand, the leg thickness can be reduced so much that the top of the leg covering the groove merges into the top of the tongue without any pronounced step formation. The greater the angle of inclination of the tongue and groove is selected, the stronger the legs of the matrix-shaped bridge member can be wedge-shaped, whereby a continuous, almost completely level flowing transition from one part of the building to the other is guaranteed.

Nach einer Ausgestaltung der Erfindung sind der Nut bzw. Feder abgewandte Randstreifen der Brückenglieder jeweils bogenförmig zum Bauwerksboden hinweisend ausgebildet und greifen in eine entsprechend bogenförmig verlaufende Nut ein, die in jeder Verankerungseinheit vorgesehen ist.According to one embodiment of the invention, the edge strips of the bridge members facing away from the tongue or groove are each formed in an arc-shaped manner pointing towards the building floor and engage in a correspondingly arc-shaped groove which is provided in each anchoring unit.

Durch diese Ausbildung lassen sich die Brückenglieder mit den Verankerungseinheiten so gelenkig verhaken, daß im montierten Zustand die Brückenglieder gegenüber den Verankerungseinheiten in ausreichendem Maße verschwenkbar bleiben, jedoch nicht unbefugterweise aus den Nuten der Verankerungseinheiten entfernt werden können.With this design, the bridge members can be hooked to the anchoring units in such an articulated manner that in the assembled state the bridge members remain sufficiently pivotable relative to the anchoring units, but cannot be removed from the grooves of the anchoring units without authorization.

Vorzugsweise ist dazu die in den Verankerungseinheiten jeweils vorgesehene Nut zur Fugenseite hin durch ein Walzenstück und von der Fugenseite weg durch ein Schalenstück begrenzt. Dieses übergreift jeweils einen bogenförmigen Randstreifen eines Brückenglieds und bildet mit diesem gleichfalls einen fließenden Übergang von der Oberseite des Brückenglieds zu einer Stirnfläche der Verankerungseinheit.For this purpose, the groove provided in the anchoring units is preferably delimited to the joint side by a roller piece and away from the joint side by a shell piece. This overlaps an arcuate edge strip of a bridge member and likewise forms a smooth transition from the top of the bridge member to an end face of the anchoring unit.

Vorzugsweise ist jede Verankerungseinheit aus einem Winkelprofil gebildet, an dessen zum Bauwerksboden senkrecht ausgerichteten und nach oben weisenden Schenkel das Walzenstück und das Schalenstück angeformt sind.Each anchoring unit is preferably formed from an angular profile, on the legs of which are oriented vertically to the building floor and point upwards, the roller piece and the shell piece are formed.

Soll die Vorrichtung in Bauwerksböden eingesetzt werden, wobei unterschiedlich starke Bodenbeläge in Betracht kommen, kann es sich zur Reduzierung einer Vielzahl von Verankerungseinheiten aus unterschiedlichen Winkelprofilen empfehlen, die Verankerungseinheit aus einem Winkelprofil zu bilden, auf dessen zum Bauwerksboden senkrecht ausgerichteten und nach oben weisenden Schenkel ein Zwischenprofil aufsetzbar ist, an dem das Walzenstück und das Schalenstück angeformt sind.If the device is to be used in building floors, with floor coverings of different thicknesses being considered, it may be advisable to reduce the number of anchoring units from different angled profiles by forming the anchoring unit from an angled profile on the leg perpendicular to the building floor and pointing upwards Intermediate profile can be placed on which the roller piece and the shell piece are molded.

Bei einer derartigen Ausbildung genügt es, zur Berücksichtigung unterschiedlich starker Bodenbeläge verschieden hohe Zwischenprofile auf einheitliche Winkelprofile aufzusetzen, um die Verankerungseinheiten an die jeweils geforderte Belagstärke anzupassen.With such a design, it is sufficient, in order to take into account floor coverings of different thicknesses, to place intermediate profiles of different heights on uniform angle profiles in order to adapt the anchoring units to the required covering thickness.

Schließlich sieht eine Ausgestaltung der Erfindung noch vor, daß die Querschnittsmittelachse der Nut und Feder in einem konkaven oder konvexen Bogen verläuft, dessen Radius mindestens der zweifachen maximalen Fugenbreite entspricht.Finally, an embodiment of the invention provides that the central cross-sectional axis of the tongue and groove runs in a concave or convex arc, the radius of which corresponds to at least twice the maximum joint width.

Durch diese Ausgestaltung kann der fließende Übergang von einem Bauwerksteil zum anderen noch dadurch verbessert werden, daß die Oberseite der Brückenglieder in einem entsprechend konkaven oder konvexen Bogen verlaufen, der bei einer Niveauveränderung eines Bauwerksteils gegenüber dem anderen und auch bei sich ändernder Fugenbreite zwischen den Bauwerksteilen den fließenden Übergang zwischen diesen weiterhin garantiert.With this configuration, the smooth transition from one part of the building to the other can be further improved in that the top of the bridge members run in a correspondingly concave or convex arc, which in the event of a change in the level of one part of the building relative to the other and also in the case of a change in the joint width between the parts of the building, the smooth transition between them is still guaranteed.

Die Vorteile der erfindungsgemäßen Vorrichtung lassen sich wie folgt zusammenfassen:
- Die Vorrichtung stellt ein zweigelenkiges Teleskopsystem dar, wobei die Überbrückungseinheit aus nur zwei Brückengliedern besteht und die beiden Verankerungseinheiten wahlweise jeweils ein oder zweiteilig ausgebildet sein können.
- Die Vorrichtung ermöglicht eine weitgehend ebene Sichtfläche, wobei selbst bei dreidimensionalen Relativbewegungen der durch die Fugen getrennten Bauteile ein stoßfrei überfahrbarer Übergang aufrechterhalten wird.
- Die gelenkige hakenförmige Verbindung zwischen der Überbrückungseinheit und den Verankerungseinheiten führt zu einem sehr günstigen Verhältnis zwischen der Sichtbreite und der maximalen Fugenbreite.
- Die Vorrichtung läßt sich in einer geringen Bauhöhe ausführen, wobei sich zudem aufeinanderfolgende Längen der Vorrichtungseinzelteile versetzt zueinander anordnen lassen, so daß sich eine seiten- und höhengleiche Verbindung der Vorrichtungseinzelteile über die volle Fugenlänge gewährleisten läßt.
- Schließlich läßt sich die Vorrichtung besonders vorteilhaft in Hartestrichen einsetzen, ohne daß Aussparungen im Bauwerksboden erforderlich sind.The advantages of the device according to the invention can be summarized as follows:
- The device is a two-articulated telescope system, the bridging unit consists of only two bridge members and the two anchoring units can optionally be formed in one or two parts.
- The device enables a largely flat visible surface, whereby a smooth transition that can be driven over is maintained even with three-dimensional relative movements of the components separated by the joints.
- The articulated hook-shaped connection between the bridging unit and the anchoring units leads to a very favorable ratio between the visible width and the maximum joint width.
- The device can be carried out in a low overall height, wherein successive lengths of the individual device parts can also be arranged offset from one another, so that an equal-sided and equal connection of the individual device parts can be ensured over the full joint length.
- Finally, the device can be used particularly advantageously in hard screeds without the need for recesses in the building floor.
