Description

Einleitungintroduction

Die Erfindung betrifft eine Vorrichtung zur Überbrückung einer Fuge zwischen zwei Bauwerksteilen, mit zwei auf jeweils einander gegenüber liegenden Seiten der Fuge mit dem jeweiligen Bauwerksteil verankerbaren Verankerungseinheiten und einer die beiden Verankerungseinheiten verbindenden und die Fuge überbrückenden Überbrückungseinheit, wobei die Vorrichtung in Abhängigkeit einer sich ändernden Breite der Fuge eine sich anpassende Breite annimmt und wobei die Verankerungseinheiten und/oder die Überbrückungseinheit aus Aluminium bestehende Strangpressprofile sind.The invention relates to a device for bridging a joint between two parts of the structure, with two anchoring units anchored on respective opposite sides of the joint to the respective structural part and a bridging unit connecting the two anchoring units and bridging the joint, the device being dependent on a changing width the joint assumes an adaptive width and wherein the anchoring units and / or the bridging unit are extruded aluminum profiles.

Vorrichtungen zur Überbrückung einer Dehnfuge, die im Folgenden auch als Fugenprofil bezeichnet werden, sind derart aufgebaut, dass sie unter Verbindung zweier Bauwerksteile horizontale Relativbewegungen zwischen den beiden Bauwerksteilen, wie sie z.B. an Brücken- oder Gebäudebauabschnitten auftreten, zulassen. Solche Relativbewegungen können durch Witterungsverhältnisse, Bauzustände oder Belastungen der Bauwerksteile entstehen. Die Fugenprofile bestehen in der Regel aus zwei Verankerungseinheiten, die jeweils mit den ihnen zugeordneten Bauwerksteilen über Befestigungsflansche fest verbunden sind, und aus einer Überbrückungseinheit, die entweder aus einem an den Verankerungseinheiten befestigten flexiblen bzw. faltbaren Material oder zwei oder mehreren zu den Verankerungseinheiten und relativ zueinander beweglich gelagerten starren Bauteil aufgebaut sind.Devices for bridging an expansion joint, which are also referred to below as joint profile, are constructed such that, with the connection of two structural parts, horizontal relative movements between the two structural parts, as e.g. at bridge or building sections, allow. Such relative movements can be caused by weather conditions, construction conditions or loads on the building parts. The joint profiles usually consist of two anchoring units, which are fixedly connected to their associated building parts via mounting flanges, and a bridging unit, either from a fixed to the anchoring units flexible or foldable material or two or more to the anchoring units and relative movably mounted rigid component are constructed.

Dergestalt ausgebildete Fugenprofile sind dem Stand der Technik nach bekannt. So beschreiben z.B. die Druckschriften CA 2 194 506 , DE 30 20 035 A1 , DE 23 44 225 A1 und CH 548 491 Fugenprofile, bei denen die Überbrückungseinheit aus einem elastischen und/oder faltbaren Material besteht, wobei bei den beiden letzteren Druckschriften zusätzlich ein zu den Verankerungseinheiten bewegliches, starres Trägerbauteil eingebaut ist, das das elastische Überbrückungsteil tragend unterstützt. Starre, bezüglich der Verankerungseinheiten beweglich gelagerte Bauteile als Überbrückungseinheiten, die insbesondere für Brückenbauwerke Verwendung finden, werden in unterschiedlicher Ausführung z.B. in den Druckschriften DE 197 05 531 A1 und DE 30 50 317 C1 offenbart. Diese starren Bauteile werden in der Regel aus Stahl hergestellt, können jedoch auch aus stranggepresstem Aluminium oder aber Kunststoff ( DE 20 2005 014 500 U1 ) bestehen.Such trained joint profiles are known in the art. For example, describe the pamphlets CA 2 194 506 . DE 30 20 035 A1 . DE 23 44 225 A1 and CH 548 491 Joint profiles in which the bridging unit consists of an elastic and / or foldable material, wherein in the two latter documents in addition to the anchoring units movable, rigid support member is installed, which supports supporting the elastic bridging member. Rigid, with respect to the anchoring units movably mounted components as bridging units, which are used in particular for bridge structures are in different versions, for example in the publications DE 197 05 531 A1 and DE 30 50 317 C1 disclosed. These rigid components are usually made of steel, but can also be made of extruded aluminum or plastic ( DE 20 2005 014 500 U1 ) consist.

Der Nachteil der aus Stahl hergestellten Fugenprofile liegt darin, dass sie optisch nicht immer ansprechend sind, insbesondere können sie nach einiger Zeit Rostspuren aufweisen, die sich oft auch auf die angrenzenden Betonbauteile ausbreiten. Leichter und schneller herzustellende Fugenprofile aus Aluminium oder Kunststoff, deren Optik länger erhalten bleibt, haben dagegen den Nachteil, dass sie durch eine zum Teil unzureichende Oberflächenhärte eine geringere Abriebfestigkeit aufweisen und damit höhere Kosten durch Wartung und Erneuerung verursachen. Um dies zu umgehen, sind aus dem Stand der Technik auch Fugenprofile bekannt, die vollständig aus Edelstahl hergestellt sind. Neben dem höheren Fertigungsaufwand gegenüber den Fugenprofilen aus stranggepresstem Aluminium oder Kunststoff wirken sich bei den aus Edelstahl gefertigten Fugenprofilen zusätzlich die erheblich höheren Materialkosten nachteilig aus.The disadvantage of the joint profiles made of steel is that they are not always visually appealing, in particular, they may after some time have rust marks, which often spread to the adjacent concrete components. On the other hand, lighter and faster joint profiles made of aluminum or plastic, whose appearance remains longer, have the disadvantage that they have lower abrasion resistance due in some cases to insufficient surface hardness and thus to higher costs due to maintenance and renewal. To avoid this, joint profiles are known from the prior art, which are made entirely of stainless steel. In addition to the higher production costs compared to the joint profiles made of extruded aluminum or plastic, the considerably higher material costs also have a disadvantageous effect on the joint profiles made of stainless steel.

Aufgabetask

Aufgabe der vorliegenden Erfindung ist es daher, ausgehend von den aus dem Stand der Technik her bekannten, einfach und kostengünstig herzustellenden Fugenprofile aus stranggepresstem Aluminium, die Eigenschaften und die Optik der Fugenprofiloberflächen zu verbessern.It is therefore an object of the present invention to improve the properties and the appearance of the joint profile surfaces, starting from the extrusion profiles of extruded aluminum which are known from the prior art and can be produced easily and cost-effectively.

Lösungsolution

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass die Verankerungseinheiten und/oder die Überbrückungseinheit zum Teil aus Edelstahl und/oder Messing und/oder Bronze bestehen. Dadurch wird unter Beibehaltung des preisgünstigen und leicht auch mit größeren Ausmaßen herzustellende Aluminium-Strangpressprofils teures Edelstahl-, Messing- bzw. Bronzematerial eingespart. Auch gesteigerten Anforderungen an die Ästhetik in der Architektur kann damit auf kostensparende Weise entsprochen werden, insbesondere wenn in dem Bauwerk auch sonst "silberfarbige" Edelstahlteile oder eher "goldfarbige" Messingteile bzw. bronzefarbige Teile Verwendung finden. Gegenüber einer Lackbeschichtung zeichnen sich die erfindungsgemäß vorgeschlagenen "Echtmetall-Beschichtungen" durch eine verbesserte Haltbarkeit aus.This object is achieved according to the invention in that the anchoring units and / or the bridging unit consist partly of stainless steel and / or brass and / or bronze. This saves expensive stainless steel, brass or bronze material while retaining the inexpensive extruded aluminum profile, which can easily be produced with larger dimensions. Also, increased demands on the aesthetics of architecture can thus be met in a cost-saving manner, especially if otherwise "silver-colored" stainless steel parts or rather "gold-colored" brass parts or bronze-colored parts are used in the building. Compared with a lacquer coating, the inventively proposed "real metal coatings" are characterized by improved durability.

Eine bevorzugte Ausführungsform ist dabei, dass im Einbauzustand der Vorrichtung nur die sichtbaren Oberflächenbereiche aus Edelstahl und/oder Messing und/oder Bonze bestehen, was bei hoher Abriebfestigkeit der Profiloberfläche und langanhaltender guter Optik zu einer Materialeinsparung und damit Kostenersparnis führt. Um eine einheitliche Optik zu gewährleisten, sollen jedoch vorteilhafter Weise sämtliche sichtbaren Oberflächenbereiche im Einbauzustand der Vorrichtung aus Edelstahl und/oder aus Messing und/oder aus Bronze bestehen.A preferred embodiment is that in the installed state of the device only the visible surface areas made of stainless steel and / or brass and / or Bonze exist, resulting in high abrasion resistance of the tread surface and long-lasting good appearance to a material saving and thus cost savings. To ensure a uniform appearance, However, all visible surface areas in the installed state of the device should advantageously consist of stainless steel and / or brass and / or bronze.

Eine weitere Ausführungsform sieht vor, dass die Aluminium-Strangpressprofile mit Edelstahl und/oder Messing und/oder Bronze beschichtet werden. Die Beschichtung kann dabei aus einer Edelstahl-, Messing- oder Bronzefolie oder einer Edelstahl- oder Messing- oder Bronzeplattierung bestehen, was wiederum zu einer zusätzlichen Materialersparnis führt, ohne die Optik oder die Abriebfestigkeit zu beeinträchtigen. Für eine gute Haftung der Beschichtung am Aluminium-Strangpressprofil soll diese mit dem Aluminium-Strangpressprofil stoffschlüssig verbunden werden. Dies kann insbesondere durch Verkleben geschehen, wobei als Kleber dafür vorzugsweise ein Zweikomponenten-Epoxidharzklebstoff vorgesehen ist.A further embodiment provides that the aluminum extruded profiles are coated with stainless steel and / or brass and / or bronze. The coating may consist of a stainless steel, brass or bronze foil or a stainless steel or brass or bronze cladding, which in turn leads to an additional material savings, without affecting the appearance or the abrasion resistance. For a good adhesion of the coating on the aluminum extruded profile it should be materially connected to the aluminum extruded profile. This can be done in particular by gluing, wherein as a glue for preferably a two-component epoxy resin adhesive is provided.

Weiterhin ist es von Vorteil, wenn die Folie oder Plattierung aus Edelstahl, Messing oder Bronze gefalzt ist und zwei in einem Winkel zueinander verlaufende und durch eine Kante voneinander getrennte Flächen des Aluminium-Strangpressprofils überdeckt. Dies führt zu einem zusätzlichen Halt der Folie bzw. der Plattierung am Aluminium-Strangpressprofil.Furthermore, it is advantageous if the foil or plating is folded from stainless steel, brass or bronze and covers two mutually at an angle and separated by an edge surfaces of the aluminum extruded profile. This leads to an additional hold of the film or the cladding on the aluminum extruded profile.

Zur Erzielung einer Elastizität des Fugenprofils ist in einer speziellen Ausführungsform vorgesehen, dass die Überbrückungseinheit zumindest teilweise aus einem gummielastischen Material besteht. Alternativ kann es sinnvoll sein, das Kompensationsvermögen für Relativbewegungen dadurch zu schaffen, dass die Überbrückungseinheit vorteilhafter Weise an den gegenüberliegenden Enden der Seitenteile mit der jeweils zugeordneten Verankerungseinheit gelenkig verbunden ist.To achieve an elasticity of the joint profile is provided in a special embodiment that the bridging unit consists at least partially of a rubber-elastic material. Alternatively, it may be useful to provide the compensation capability for relative movements in that the bridging unit is advantageously connected at the opposite ends of the side parts with the respectively associated anchoring unit articulated.

Damit selbst bei Relativbewegungen der Bauwerksteile unabhängig von der Winkelposition des die Überbrückungseinheit mit der Verankerungseinheit verbindenden Gelenks zu jeder Zeit nur Edelstahl-, Messing- oder Bronzeoberflächen zu sehen sind, ist insbesondere vorgesehen, dass die Edelstahl-, Messing- oder Bronzebeschichtung im einem Bereich von an den Enden der Seitenteile befindlichen Drehgelenkbuchsen einen gekrümmten Endabschnitt aufweist. Dieser gekrümmte Endabschnitt erstreckt sich unter einer Kante einer Drehgelenkhalterung hinweg in einen Spaltbereich zwischen dieser Drehgelenkhalterung und der Drehgelenkbuchse hinein.Thus, even with relative movements of the building parts regardless of the angular position of the bridging unit with the anchoring unit connecting joint at any time only stainless steel, brass or bronze surfaces can be seen, is provided in particular that the stainless steel, brass or bronze coating in a range of At the ends of the side parts located rotary joint bushings has a curved end portion. This curved end portion extends below an edge of a hinge mount into a gap area between this hinge mount and the pivot socket.

Schließlich sieht eine besondere Ausgestaltungsform der Erfindung vor, dass die Breite der Überbrückungseinheit dadurch veränderbar ist, dass zwei Teile der starr ausgeführten Überbrückungseinheit nach Art einer Nut-Feder-Verbindung ineinander verschiebbar sind. Dies erlaubt in hohem Maße einen Bewegungsausgleich bei Relativbewegungen der Bauwerksteile durch Witterungseinflüsse, unterschiedliche Bauzustände oder Belastungen bei gleichzeitiger hoher Tragkraft senkrecht zur Oberfläche des Fugenprofils.Finally, a particular embodiment of the invention provides that the width of the bridging unit can be changed by virtue of the fact that two parts of the rigidly executed bridging unit are slidable into one another in the manner of a tongue and groove connection. This allows a high degree of motion compensation for relative movements of the building parts due to weather conditions, different construction conditions or loads with simultaneous high load capacity perpendicular to the surface of the joint profile.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels für eine Beschichtung einer Vorrichtung zur Überbrückung einer Dehnfuge mit Edelstahl näher erläutert. Bei einer alternativen oder kombinierten Beschichtung der Vorrichtung mit Messing oder Bronze könnte die Ausführung analog erfolgen.In the following, the invention will be explained in more detail with reference to an embodiment shown in the drawing for a coating of a device for bridging an expansion joint with stainless steel. In an alternative or combined coating of the device with brass or bronze, the execution could be analogous.

Die auf den Befestigungsflanschen 9 sitzenden Drehgelenkhalterungen 10 werden mittels Schrauben 17 gesichert. An den Drehgelenkhalterungen 10 sind dehnfugenseitig Drehgelenkachsen 19 a n-gebracht, die im zusammengebauten Zustand der Vorrichtung 1 in Drehgelenkbuchsen 20 der Seitenteile 7 der Überbrückungseinheit 5 sitzen, um Drehgelenke 18 zu bilden, die dem Ausgleich von vertikalen Relativbewegungen der Bauwerksteile 3 dienen, wie sie durch Setzerscheinungen oder auch Belastungen der Bauwerksteile 3 senkrecht zur Fugenprofiloberfläche auftreten können.Through holes in the mounting flanges 9 are, as in FIG. 2 illustrates the anchoring units 4 by means of anchors 11 attached to the building parts 3. The seated on the mounting flanges 9 pivot supports 10 are secured by screws 17. On the hinge brackets 10 are expansion joint side pivot axes 19 a n-brought sitting in the assembled state of the device 1 in pivot bushings 20 of the side parts 7 of the bridging unit 5 to form hinges 18, which serve to compensate for vertical relative movements of the building parts 3, as they can occur by settling or even loads of building parts 3 perpendicular to the joint profile surface.

By coating the top of the swivel mounts 10 with stainless steel foil or in the form of a stainless steel plating also the fastening screws 17 which connect the swivel mounts 10 with the mounting flanges 9, protected against environmental influences or against disassembly by unauthorized persons. The stainless steel coating 23 should have a thickness of about 1.0 mm and is in the FIGS. 1 to 3 shown for better identification by a thickened line.

In die Hohlräume der Nuten 14 eindringende Feuchtigkeit und Schmutz könnten die Beweglichkeit des Mittelteils 6 der Überbrückungseinheit 5 einschränken und somit die Funktion der Vorrichtung 1 zur Überbrückung von Dehnfugen beeinträchtigen. Um dies zu verhindern, befinden sich an der Oberseite des Mittelteils 6 der Überbrückungseinheit 5 endseitig zu den Bauwerksteilen 3 hin in Nuten eingebettete in Form von Schnüren ausgebildete Dichtungen 21 aus einem gummielastischen Material, die zusammen mit den oberen Wangen 12 die Nuten 14 der Seitenteile 7 von oben abdichten. Gleichartige Dichtungen 22 befinden sich an der Oberseite der Drehgelenkbuchsen 20, die den Spalt zwischen den Drehgelenkhalterungen 10 und den Drehgelenkbuchsen 20 verschließen, um auch hier dauerhaft eine einwandfreie Beweglichkeit zu gewährleisten. Diese Beweglichkeit der Drehgelenke 18 wird zudem durch einen von der Edelstahlbeschichtung 23 freigehaltenen schmalen Bereich 24 auf dem oberen Teil der Drehgelenkbuchsen 20 sichergestellt.In the cavities of the grooves 14 penetrating moisture and dirt could limit the mobility of the central part 6 of the bridging unit 5 and thus affect the function of the device 1 for bridging expansion joints. To prevent this, are located at the top of the central part 6 of the bridging unit 5 end to the building parts 3 out in grooves embedded in the form of strings seals 21 made of a rubber-elastic material, which seal together with the upper cheeks 12, the grooves 14 of the side parts 7 from above. Similar seals 22 are located at the top of the pivot bushings 20, which close the gap between the swivel mounts 10 and the pivot bushings 20, to ensure a permanent mobility here, too. This mobility of the hinges 18 is also ensured by a kept free of the stainless steel coating 23 narrow portion 24 on the upper part of the pivot bushes 20.

Alternativ kann jedoch auch dieser auf dem oberen Teil der Drehgelenkbuchsen 20 befindliche Bereich 24 mit einer Edelstahlbeschichtung 23 abgedeckt werden. Die Edelstahlbeschichtung 23 wird dazu auf der äußeren Seite des oberen Teils der Drehgelenkbuchsen 20 gekrümmt um diese herumgeführt und verklebt. Dabei erstreckt sich dann die Edelstahlbeschichtung 23 unter einer Kante 25 der Drehgelenkhalterung 10 hinweg in den Spalt zwischen dem oberen Teil der Drehgelenkbuchse 20 und der Drehgelenkhalterung 10 hinein, und zwar soweit, dass in jeder Winkelposition des Drehgelenks 18 von den Oberflächenseiten der Verankerungseinheiten 4 und der Überbrückungseinheiten 5 her nur die Edelstahlbeschichtung 23 zu sehen ist. Dies gewährleistet zu jedem Zeitpunkt eine einheitliche gute Oberflächenoptik. Die Abdichtung des Spaltes zwischen den Drehgelenkbuchsen 20 und den Drehgelenkhalterungen 10 durch schnurförmige Dichtungen 22 wird durch diese alternative Ausführung nicht berührt.Alternatively, however, this located on the upper part of the pivot bushes 20 area 24 can be covered with a stainless steel coating 23. The stainless steel coating 23 is curved on the outer side of the upper part of the pivot bushings 20 around this and led around and glued. In this case, then the stainless steel coating 23 extends under an edge 25 of the pivot bracket 10 in the gap between the upper part of the pivot bushing 20 and the pivot bracket 10 in, to the extent that in any angular position of the pivot joint 18 from the surface sides of the anchoring units 4 and Bridging 5 ago only the stainless steel coating 23 can be seen. This ensures a uniform, good surface appearance at all times. The sealing of the gap between the pivot bushes 20 and the pivot supports 10 by cord-shaped seals 22 is not affected by this alternative embodiment.
