Abstract

The member comprises two sheet metal edge strips (11,12) and a synthetic rubber middle strip (30) joined to the edge strips by vulcanisation. At one end of the expansion member, the edge strips are joined together to form a zero movement point. Along the synthetic rubber strip, one edge strip (12) is overlapped over the other to form a protective covering. Preferably, one (11) of the strips has a cut-out in the area of the zero movement point and the other edge strip is welded to the edge of the cut-out.

Description

Die Erfindung betrifft ein Dilatationselement zur Fugenüberbrückung an Bauwerken. Ein solches Dilatationselement ist z.B. aus der DE-OS 31 00 775, insbesondere Seite 6, letzter Absatz, bekannt. Einzelheiten zu Dilatationselementen mit Bewegungsnullpunkt finden sich auch z.B. in der DE-PS 17 09 019 und in der DE-PS 24 29 430. Der Inhalt der drei genannten Schriften wird insoweit hiermit zum Gegenstand der Offenbarung in der vorliegenden Anmeldung gemacht, so daß sich hier eine detaillierte Beschreibung der Funktion des Dilatationselements mit Bewegungsnullpunkt erübrigt.The invention relates to a dilation element for bridging joints on buildings. On such a dilation element is e.g. from DE-OS 31 00 775, in particular page 6, last paragraph, known. Find details of dilation elements with zero movement also e.g. in DE-PS 17 09 019 and in DE-PS 24 29 430. The The content of the three cited documents is hereby the subject of the disclosure made in the present application, so that here is a detailed description of the Function of the dilatation element with zero point of movement is superfluous.

Bei dem aus der erstgenannten Druckschrift bekannten Dilatationselement wurde eine Blechabdeckung unmittelbar auf die Oberseite des Kunstgummimittelstreifens aufvulkanisiert. Diese Blechabdeckung, auch Zunge genannt, mußte als getrenntes Bauteil hergestellt werden, wobei die beiden Blechrandstreifen aus einem einzigen Blech hergestellt, also über den Bewegungsnullpunkt hinweg einstückig miteinander verbunden waren. In dem sich von dem Bewegungsnullpunkt weg erstreckenden längeren Teil des Dilatationselements mußte zwischen den Blechrandstreifen bei der Herstellung ein Freiraum ausgestanzt werden, um eine Dilatationsbewegung zu ermöglichen. -Dadurch lag zwischen den Blechrandstreifen der Kunstgummimittelstreifen nach dem Vulkanisieren zunächst frei. Die getrennt hergestellte Blechabdeckung oder Zunge diente dazu, diesen freien Bereich des Kunstgummimittelstreifens zum Schutz gegen Umwelteinflüsse (Sonneneinstrahlung, Ozon, Feuchtigkeit, Eis, Staub und anderer Schmutz, aber auch gegen Betreten durch Bauarbeiter usw.) abzudecken und zu sichern. Die Blechabdeckung oder Zunge wurde in einem Arbeitsgang längs des Mittelbereichs unmittelbar auf die Oberseite des Kunstgummimittelstreifens aufvulkanisiert.In the dilation element known from the first-mentioned publication, a sheet metal cover was used vulcanized directly onto the top of the synthetic rubber center strip. This Sheet metal cover, also called tongue, had to be manufactured as a separate component, whereby the two sheet metal edge strips are made from a single sheet, i.e. above the zero point of movement were integrally connected together. In which is from the zero point of motion extending longer part of the dilatation element had to be between the Sheet metal edge strips are punched out during manufacture to allow a dilation movement to enable. -This was between the sheet metal edge strips of the synthetic rubber center strips initially free after vulcanization. The separately manufactured sheet metal cover or tongue was used to protect this free area of the synthetic rubber center strip against environmental influences (solar radiation, ozone, moisture, ice, dust and others Cover and secure dirt, but also against entry by construction workers etc.). The The sheet metal cover or tongue became immediate in one pass along the central area vulcanized onto the top of the synthetic rubber center strip.

Für die Abdeckung des Kunstgummimittelstreifens mußte also das die Blechrandstreifen bildende Grundblech in entsprechender Weise durch Ausstanzen vorbereitet werden. Zusätzlich mußte die Blechabdeckung oder Zunge getrennt hergestellt werden. Dies bedeutet einen entsprechenden Mehraufwand.For the covering of the synthetic rubber center strip, this had to be the metal edge strips forming base plate are prepared in a corresponding manner by punching. additionally the sheet metal cover or tongue had to be made separately. This means one corresponding additional effort.

Aus DE-A-32 35 687 ist daneben ein Dehnungsausgleichselement (Dilatationselement) bekannt, das zwei Blechrandstreifen aufweist, die Teile eines einzigen, trapezförmig zugeschnittenen Bleches sind. Dieses Blech hat eine in Längsrichtung verlaufende mittlere Schnittlinie, die sich von der breiten Trapezseite bis zu einer runden Ausstanzung erstreckt, die nahe der schmalen Trapezseite angebracht ist. Die beidseitig des Schnittes verlaufenden Teile des Blechs bilden somit zwei miteinander verbundene Blechrandstreifen. Auch zur Herstellung dieses Dilatationselements mußte also das Grundblech entsprechend durch Schneiden und Ausstanzen vorbereitet werden.From DE-A-32 35 687 there is also an expansion compensation element (dilation element) known that has two sheet metal edge strips, the parts of a single, trapezoidally cut Are sheets. This sheet has a middle one running in the longitudinal direction Cutting line, which extends from the broad trapezoidal side to a round cutout, which is attached near the narrow trapezoidal side. The two sides of the cut Parts of the sheet thus form two interconnected sheet metal edge strips. Also for Production of this dilatation element had to go through the base plate accordingly Cutting and punching are prepared.

Durch die Erfindung soll ein konstruktiv einfacher ausgebildetes und in einem einfacheren Fertigungsverfahren kostengünstiger herstellbares Dilatationselement geschaffen werden.The invention is designed to be structurally simpler and simpler Manufacturing processes cost-effective to produce dilatation element.

Das erfindungsgemäße Dilatationselement ist in dem Patentanspruch 1 gekennzeichnet.The dilation element according to the invention is characterized in claim 1.

Hiernach werden zunächst statt eines einstückigen, im Mittelbereich ausgestanzten Grundblechs zwei einzelne Blechrandstreifen separat voneinder oder getrennt hergestellt und im Bereich des Bewegungsnullpunkts aneinander befestigt, um eine Dilatationsbewegung des Blechgebildes nach Art einer Stimmgabel zu ermöglichen, wobei sich also die beiden Blechrandstreifen quer zu dem Kunstgummimittelstreifen umso weiter relativ zueinander bewegen können, je weiter deren Teile von dem Bewegungsnullpunkt entfernt sind. Die getrennten Blechrandstreifen werden so aneinander befestigt, daß sie sich in Längsrichtung des Dilatationselements einander überlappen und somit im Überlappungsbereich selbst die gewünschte Blechabdeckung bilden. Ein zusätzliches Blechteil oder eine Zunge ist zur Bildung der Abdeckung nicht mehr erforderlich.According to this, instead of a one-piece base plate punched out in the central area two separate sheet metal edge strips separately from each other or manufactured separately and in the area of the zero point of motion attached to each other to prevent a dilatation movement of the sheet metal structure according to Art to enable a tuning fork, so that the two metal edge strips transversely to the Artificial rubber center strips can move relative to each other, the further their Parts are removed from the zero point of motion. The separated sheet metal edge strips are attached to each other so that they are in the longitudinal direction of the dilating element overlap and thus form the desired sheet metal cover in the overlap area itself. An additional sheet metal part or a tongue is no longer required to form the cover.

Fig. 1a zeigt zwei ebene, etwa rechtwinkelige längliche Blechrandstreifen 11 und 12 zur Herstellung eines Dilatationselements. Der eine Blechrandstreifen 11 weist an einem Ende eine Ausnehmung 13 auf, die durch einen Rand 14 begrenzt ist, der sich parallel zur Längsrichtung der beiden Blechrandstreifen 11, 12 erstreckt.Fig. 1a shows two flat, approximately rectangular elongated sheet metal edge strips 11 and 12 for Production of a dilatation element. One sheet edge strip 11 has at one end a recess 13 which is bounded by an edge 14 which is parallel to the longitudinal direction of the two metal edge strips 11, 12 extends.

Zur Herstellung eines Dilatationselements wird der rechte Blechrandstreifen 12 über den linken Blechrandstreifen 11 soweit nach links geschoben, bis der obere Teil der Seitenkante 15 des Blechrandstreifens 12 an dem Rand 14 der Ausnehmung 13 anliegt. Dieser Teil der Seitenkante 15 wird an dem Rand 14 dicht befestigt, insbesondere mit dem Rand 14 zur Bildung einer Schweißnaht 17 (Fig. 1b) dicht verschweißt. Die Schweißnaht 17 ist vorzugsweise durch stumpfes Verschweißen der beiden Blechrandstreifen 11, 12 "auf Stoß miteinander" gebildet. Dabei überlappt vorzugsweise der gemäß der Zeichnung untere linke Teil des rechten Blechrandstreifens 12 den unteren rechten Teil des linken Blechrandstreifens 11 zur Bildung eines Überlappungsbereichs 16. Der rechte Blechrandstreifen 12 könnte im Überlappungsbereich 16 auch unter dem entsprechenden Teil des linken Blechrandstreifens 11 liegen.To produce a dilatation element, the right metal edge strip 12 is placed over the Left edge strip 11 pushed to the left until the upper part of the side edge 15 of the sheet metal edge strip 12 abuts the edge 14 of the recess 13. This part of the Side edge 15 is tightly attached to the edge 14, in particular with the edge 14 to Formation of a weld seam 17 (Fig. 1b) tightly welded. The weld 17 is preferred by butt welding the two sheet metal edge strips 11, 12 "butt with one another" educated. In this case, the lower left part of the right sheet metal edge strip 12 to the lower right part of the left sheet metal edge strip 11 Formation of an overlap area 16. The right metal edge strip 12 could be in the overlap area 16 also lie under the corresponding part of the left metal edge strip 11.

Das so hergestellte einstückige Blechgebilde hat im Bereich 18 der Schweißnaht 17 einen Bewegungsnullpunkt und seine davon wegweisenden Enden sind quer zu der Schweißnaht 17 relativ zueinander beweglich, so daß nach Einbau des Dilatationselements über einer Fuge an einem Bauwerk die dort auftretenden Bewegungen durch das Dilatationselement quer zu dessen Längsrichtung aufgenommen werden können.The one-piece sheet-metal structure thus produced has one in the area 18 of the weld seam 17 The zero point of motion and its ends pointing away therefrom are transverse to the weld seam 17 movable relative to each other, so that after installing the dilatation element over a joint a building the movements occurring there through the dilation element across whose longitudinal direction can be recorded.

Zur Abdichtung der so überbrückten Bauwerksfuge ist an der Unterseite des Dilatationselements an die beiden Blechrandstreifen 11, 12 ein Mittelstreifen 30 aus Kunststoff oder Gummi (Kunstgummi) anvulkanisiert, der sich im wesentlichen über die ganze Länge des Dilatationselements bis in den Bereich 18 des Bewegungsnullpunkts oder über diesen hinaus erstreckt. Vorzugsweise verläuft der Kunstgummimittelstreifen 30 über die ganze Länge des Dilatationselements parallel zu den Blechrandstreifen 11 und 12. Durch die Überlappung 16 der Blechrandstreifen 1 1 und 12 ist eine Blechabdeckung über dem Kunstgummimittelstreifen 30 gebildet, so daß dieser gegen die oben beschriebenen Umwelteinflüsse geschützt ist.To seal the bridged structural joint is on the underside of the dilatation element a central strip 30 made of plastic or Vulcanized rubber (synthetic rubber) that extends essentially over the entire length of the Dilatation element up to or beyond the region 18 of the zero point of motion extends. The synthetic rubber center strip 30 preferably extends over the entire length of the Dilatation element parallel to the sheet metal edge strips 11 and 12. Through the overlap 16 the sheet metal edge strip 1 1 and 12 is a sheet metal cover over the synthetic rubber center strip 30 formed so that it is protected against the environmental influences described above.

Im Überlappungsbereich 16 liegt der rechte Blechrandstreifen 12 auf der dem Kunstgummimittelstreifen 30 abgewandten Seite des Dilatationselements (Fig. 4). Hierdurch ist trotz der Ausnehmung 13 in dem linken Blechrandstreifen 11 eine über die ganze Länge des Dilatationselements durchgehende Abdeckung 16 gebildet, so daß auch die Ausnehmung 13 abgedeckt ist und das fertige Dilatationselement in Längsrichtung durchgehende Oberflächen ohne Unterbrechungen aufweist.In the overlap area 16, the right sheet metal edge strip 12 lies on that of the synthetic rubber center strip 30 facing away from the dilatation element (Fig. 4). This is despite the Recess 13 in the left metal edge strip 11 over the entire length of the dilatation element continuous cover 16 formed so that the recess 13th is covered and the finished dilation element in the longitudinal direction continuous surfaces has no interruptions.

Für das in den Fig. 2a und 2b dargestellte zweite Ausführungsbeispiel sind zwei gleichartige, längs des ganzen Dilatationselements ohne Unterbrechungen durchlaufende Blechrandstreifen 22, 23 (ohne Ausnehmung 13) vorgesehen. Wie die Zeichnung zeigt, überlappt der rechte Blechrandstreifen 22 den linken Blechrandstreifen 21. Im Bereich 25 des Bewegungsnullpunkts ist der rechte Blechrandstreifen 22 auf dem linken Blechrandstreifen 21 dicht befestigt, insbesondere aufgelötet oder aufgeklebt. Man könnte hier auch an eine Schweißverbindung, z.B. durch Punktschweißen, denken. Eine Schweißverbindung der beiden aufeinanderliegenden Flächen wird jedoch kaum so dicht wie eine Klebe- oder Lötverbindung.For the second exemplary embodiment shown in FIGS. 2a and 2b, two identical, Continuous sheet metal edge strips running continuously along the entire dilatation element 22, 23 (without recess 13) are provided. As the drawing shows, the right one overlaps Sheet metal edge strip 22 the left sheet edge strip 21. In the area 25 of the zero point of movement the right metal edge strip 22 is tightly fastened on the left metal edge strip 21, especially soldered or glued. You could also get a welded joint here, e.g. by spot welding, think. A welded connection of the two superimposed However, surfaces hardly become as dense as an adhesive or soldered connection.

Auch bei diesem Ausführungsbeispiel nach Fig. 2b ergibt sich ein Überlappungsbereich 26 zwischen den beiden Blechrandstreifen 21 und 22. An deren Unterseite ist wiederum ein Kunstgummimittelstreifen 30 anvulkanisiert, wie es auch aus Fig. 4 ersichtlich ist. Auch bei diesem Ausführungsbeispiel läuft der Kunstgummimittelstreifen 30 vorzugsweise über die ganze Länge des Dilatationselements durch.An overlap region 26 also results in this embodiment according to FIG. 2b between the two sheet metal edge strips 21 and 22 Vulcanized synthetic rubber middle strip 30, as can also be seen from FIG. 4. Also at In this exemplary embodiment, the synthetic rubber center strip 30 preferably runs over the entire length of the dilatation element.

Für das in den Fig. 3a und 3b dargestellte dritte Ausführungsbeispiel sind wiederum zwei gleichartige, im wesentlichen rechteckige Blechrandstreifen 31, 32 vorgesehen. Hier weist jedoch der eine Blechrandstreifen 32 zur späteren Abgrenzung des Bereichs 35 des Bewegungsnullpunkts einen quer zu seiner Längsrichtung verlaufenden Einschnitt 33 auf. Im übrigen verlaufen beide Blechrandstreifen 31, 32 über die ganze Länge des späteren Dilatationselements ohne Unterbrechungen, also insbesondere ohne eine Ausnehmung 13. Das Verbinden der beiden Blechrandstreifen 31, 32 miteinander kann dabei wie bei dem Beispiel gemäß Fig. 2b erfolgen. Der rechte Blechrandstreifen 32 wird jedoch vorzugsweise mit dem linken Blechrandstreifen 31 scherenartig derart zusammengefügt, daß der Blechrandstreifen 32 auf der in der Zeichnung unteren Seite des Einschnitts 33 zur Bildung eines Überlappungsbereichs 36 über dem anderen Blechrandstreifen 31 liegt, während dieser Blechrandstreifen 32 auf der anderen, in der Zeichnung oben liegenden Seite des Einschnitts 33 zur Bildung des Bereichs 35 des Bewegungsnullpunkts unter dem anderen Blechrandstreifen 31 liegt. Die Anordnung kann auch umgekehrt getroffen werden. Im Bereich 35 sind die beiden Blechrandstreifen 31, 32 wiederum dicht miteinander verbunden, wie bei dem Beispiel nach Fig. 2b. Im Bereich des Einschnitts 33 wird der Blechrandstreifen 32 vorzugsweise entsprechend abgekröpft. Zusätzlich kann auch der andere Blechrandstreifen 31 im Bereich gegenüber dem Einschnitt 33 entsprechend in entgegengesetzter Richtung abgekröpft sein. Diese quer zur Längsrichtung der Blechrandstreifen 31, 32, bzw. parallel zu dem Einschnitt 33 verlaufenden Abkröpfungen sind in der Zeichnung nicht wiedergegeben.For the third exemplary embodiment shown in FIGS. 3a and 3b there are again two Similar, substantially rectangular sheet metal edge strips 31, 32 are provided. Here points however, the one sheet metal edge strip 32 for later delimitation of the region 35 of the zero point of motion an incision 33 extending transversely to its longitudinal direction. in the the rest of the two sheet metal edge strips 31, 32 run over the entire length of the later dilatation element without interruptions, in particular without a recess 13. Das The two sheet metal edge strips 31, 32 can be connected to one another as in the example according to FIG. 2b. The right sheet metal edge strip 32 is, however, preferably with the Left sheet edge strip 31 assembled like a scissors such that sheet edge strip 32 on the lower side of the cut 33 in the drawing to form an overlap region 36 lies above the other sheet metal edge strip 31, while this sheet metal edge strip 32 on the other, in the drawing above side of the incision 33 to form the Area 35 of the zero point of movement lies under the other sheet edge strip 31. The The order can also be reversed. In area 35 are the two sheet metal edge strips 31, 32 in turn tightly connected to one another, as in the example according to FIG. 2b. in the In the area of the incision 33, the sheet metal edge strip 32 is preferably bent accordingly. In addition, the other sheet metal edge strip 31 in the area opposite the Incision 33 be cranked accordingly in the opposite direction. This across Longitudinal direction of the sheet metal edge strips 31, 32, or extending parallel to the incision 33 Elbows are not shown in the drawing.

Eine entsprechende, schräg zur Längsrichtung des Dilatationselements verlaufende Abkröpfung kann auch bei dem Ausführungsbeispiel nach Fig. 1a und Fig. 1b im Bereich der schrägen Kante 19 des Blechrandstreifens 11 an einem oder an beiden Blechrandstreifen 11, 12 vorgesehen sein.A corresponding bend running obliquely to the longitudinal direction of the dilation element can also in the embodiment of FIGS. 1a and 1b in the area of inclined edge 19 of the sheet metal edge strip 11 on one or both sheet metal edge strips 11, 12 may be provided.

Fig. 4 zeigt, daß derjenige Blechrandstreifen 12; 22; 32, der im Überlappungsbereich 16; 26; 36 auf der dem Kunstgummimittelstreifen 30 abgewandten Seite des Dilatationselements liegt, längs des Überlappungsbereichs 16; 26; 36 abgekröpft ist (Abkröpfung 27). Damit liegen die Unterseiten der beiden Blechrandstreifen 11, 12 bzw. 21, 22 bzw. 31, 32 in dem Bereich, in dem der Kunstgummimittelstreifen 30 anvulkanisiert ist, in einer Ebene, so daß ein gutes Vulkanisieren möglich ist. Ohne die Abkröpfung 27 würde der rechte Blechrandstreifen 12; 22; 32 mit seiner Unterseite eine Stufe gegenüber der Unterseite des linken Blechrandstreifens 11; 21; 31 bilden, so daß das Anvulkanisieren des Kunstgummimittelstreifens 30 schwieriger wäre.Fig. 4 shows that the sheet metal edge strip 12; 22; 32, which in the overlap area 16; 26; 36 lies on the side of the dilatation element facing away from the synthetic rubber middle strip 30, along the overlap region 16; 26; 36 is cranked (cranking 27). With that lie the Undersides of the two sheet metal edge strips 11, 12 or 21, 22 or 31, 32 in the area in which the vulcanized rubber strip 30 is vulcanized in one plane, so that a good Vulcanization is possible. Without the offset 27, the right metal edge strip 12; 22; 32 with its underside a step opposite the underside of the left metal edge strip 11; 21; Form 31, so that the vulcanization of the synthetic rubber center strip 30 more difficult would.

Wie Fig. 4 ferner zeigt, ist vorzugsweise der Kunstgummimittelstreifen 30 an die Unterseiten der Blechrandstreifen 11; 21; 31 bzw. 12; 22; 32 nur in zwei Bereichen jeweils mit der Breite A anvulkanisiert, während in dem dazwischen liegenden mittleren Bereich B der Kunstgummimittelstreifen 30 nicht an die Blechrandstreifen anvulkanisiert ist, um die erforderliche, quer zur Längsrichtung des Dilatationselements gerichtete Dehnungs- oder Schrumpfbewegung zuzulassen. Um beim Vulkanisiervorgang ein Anvulkanisieren des Bereichs B an die Unterseite der Blechrandstreifen zu verhindern, kann in diesem Bereich ein Trennmittel, z. B. Silikon oder ein Trennlack oder auch eine Trennfolie (nicht gezeigt) eingebracht werden. As FIG. 4 further shows, the synthetic rubber center strip 30 is preferably on the undersides the sheet metal edge strip 11; 21; 31 or 12; 22; 32 only in two areas each with the width A vulcanized, while in the intermediate area B the synthetic rubber center strip 30 is not vulcanized to the sheet metal edge strips in order to achieve the required stretching or shrinking movement directed transversely to the longitudinal direction of the dilatation element permit. In order to vulcanize the area B to the vulcanizing process To prevent the underside of the metal edge strips, a release agent, e.g. B. Silicone or a release lacquer or a release film (not shown) can be introduced.

Im Gegensatz hierzu wird im Bereich 18; 25; 35 des Bewegungsnullpunkts der Kunstgummimittelstreifen 30 vorzugsweise vollflächig an die Unterseite der Blechrandstreifen 11, 12; 21, 22; 31, 32 anvulkanisiert, da hier eine Querbewegung, also ein Dehnen oder Schrumpfen des Kunstgummimittelstreifens 30 nicht erforderlich ist.In contrast, in area 18; 25; 35 of the zero point of motion of the synthetic rubber median strips 30 preferably all over the underside of the sheet metal edge strips 11, 12; 21 22; 31, 32 vulcanized, since here a transverse movement, that is, a stretching or shrinking of the Artificial rubber center strip 30 is not required.

Für die Fertigung des Dilatationselements werden zunächst die Blechrandstreifen 11, 12; 21, 22; 31, 32 getrennt hergestellt, gegebenenfalls mit der Ausnehmung 13 oder mit dem Einschnitt 33, und, wie oben beschrieben, zur Herstellung des Überlappungsbereichs 16; 26; 36 miteinander dicht verbunden, wobei jede geeignete Verbindungsart wie Schweißen, Löten oder Kleben angewendet werden kann. Anschließend wird der Kunstgummimittelstreifen 30 an die Unterseite der miteinander verbundenen Blechrandstreifen 11, 12; 21, 22; 31, 32 anvulkanisiert.For the manufacture of the dilatation element, the sheet metal edge strips 11, 12; 21 22; 31, 32 manufactured separately, possibly with the recess 13 or with the incision 33, and, as described above, for producing the overlap region 16; 26; 36 tightly connected with each other, using any suitable type of connection such as welding, soldering or gluing can be applied. Then the synthetic rubber middle strip 30 to the underside of the interconnected sheet metal edge strips 11, 12; 21, 22; 31, 32 vulcanized.
