Definitions
- the invention relates to a dilatation element, the one Training the subject of the elder European patent application 97 117 944.5, which is therefore as a stand of technology in accordance with Article 54 (3) EPC.
- the separately produced sheet metal edge strips are in the area of the zero point of motion for example, tightly attached to each other in that area with each other are welded, soldered or glued.
- the present invention relates to a further development that is simple in terms of production technology and is inexpensive to manufacture and yet the required firm connection of Ensure sheet metal edge strips with each other in the area of the zero point of motion.
- the metal edge strips are by means of a to form the zero point of movement rubber film inserted and vulcanized between them firmly connected.
- It can be a synthetic rubber made of the same or a corresponding one Trade material like the synthetic rubber median strip, which the stretching movements of the Allows dilation element, or the rubber sheet can be made of another, with sheet metal vulcanizable material exist as an additional element between the sheet metal edge strips is inserted and that can be very thin.
- the drawing shows an oblique view of the underside of a dilatation element according to the invention, with individual parts of the element cut off to illustrate the overall structure are shown.
- the dilation element consists of two flat, approximately rectangular, elongated sheet metal edge strips 41 and 42. With these is a synthetic rubber middle strip 30 by vulcanization connected as the drawing shows.
- the sheet metal edge strip 42 overlaps the other sheet metal edge strip 41 on its underside so far that at the top of the element (in the Drawing the bottom) an overlap 46 is formed along the element.
- Their meaning derives from the older European application mentioned above (protection of the element and in particular the synthetic rubber middle strip 30 against environmental influences).
- the sheet metal edge strips 41 and 42 are thereby fixed to one another in an end region 45 connected that in this area 45 a rubber sheet 47 is inserted, with the one hand the Underside of the metal edge strip 41 and on the other hand the top of the metal edge strip 42 are vulcanized.
- the rubber film 47 extends in the longitudinal direction of the dilatation element from one end over a small part of its length. Also has the rubber sheet 47 approximately the width of the overlap area between the sheet metal edge strips 41 and 42. In this way, an area 45 is formed in the vulcanizing zone of the rubber film 47 in FIG which the parts of the dilation element are practically immovable against each other (zero point of movement).
- the stretching movements of the dilation element are on the opposite End initiated, where the largest in the installed state on the synthetic rubber center strip 30 Elongation of the element occurs transversely to its longitudinal direction. Because of the fixed connection in the area 45 by means of the rubber film 47 there is practically no or at most one very little transverse movement on the dilatation element, so that in the area 45 practically one Movement zero point is formed, whereby the entire dilatation element according to Art a tuning fork can move (zero point of movement in area 45, greatest lateral movement at the opposite end).
- non-vulcanizable masking tape 48 prevents vulcanization of the Sheet metal edge strips 41 and 42 in relation to the synthetic rubber central strip 30 in the central area thereof, to there the stretchability of the synthetic rubber center strip 30 transversely to the longitudinal direction to maintain the dilatation element or not to impair it. Still seals the synthetic rubber middle strip 30 the structural joint bridged by the dilatation element completely.
- the right sheet metal edge strip 42, the Masking tape 48 and the synthetic rubber center strip 30 shown cut off. Indeed these parts extend over the same length as the left metal edge strip 41. Only the vulcanized rubber sheet 47 extends from one end of the dilation element forth to the formation of the zero point of movement in the area 45 only over a relative short distance in the longitudinal direction of the dilatation element.
- the dilation element can therefore can be manufactured from the individual parts in a single operation.

Abstract
Description
Die Erfindung betrifft ein Dilatationselement, das eine Weiterbildung des Gegenstandes der älteren europäischen Patentanmeldung 97 117 944.5 darstellt, die somit als Stand der Technik gemäβ Artikel 54 (3) EPÜ anzusehen ist.The invention relates to a dilatation element, the one Training the subject of the elder European patent application 97 117 944.5, which is therefore as a stand of technology in accordance with Article 54 (3) EPC.
Nach dieser sind die getrennt hergestellten Blechrandstreifen im Bereich des Bewegungsnullpunkts zum Beispiel dadurch aneinander dicht befestigt, daß sie in diesem Bereich miteinander verschweißt, verlötet oder verklebt sind.After this, the separately produced sheet metal edge strips are in the area of the zero point of motion for example, tightly attached to each other in that area with each other are welded, soldered or glued.
Die vorliegende Erfindung entsprechend den Patentansprüchen betrifft eine Weiterentwicklung, die fertigungstechnisch einfach und kostengünstig herzustellen ist und die trotzdem die erforderliche feste Verbindung der Blechrandstreifen miteinander im Bereich des Bewegungsnullpunkts sicherstellt.The present invention according to the claims relates to a further development that is simple in terms of production technology and is inexpensive to manufacture and yet the required firm connection of Ensure sheet metal edge strips with each other in the area of the zero point of motion.
Erfindungsgemäß sind die Blechrandstreifen mittels einer zur Bildung des Bewegungsnullpunkts dazwischen eingelegten und anvulkanisierten Gummifolie fest miteinander verbunden. Dabei kann es sich um einen Kunstgummi aus dem gleichen oder einem entsprechenden Material wie der Kunstgummimittelstreifen handeln, der die Dehnungsbewegungen des Dilatationselements ermöglicht, oder die Gummifolie kann aus einem anderen, mit Blech vulkanisierfähigen Material bestehen, das als zusätzliches Element zwischen die Blechrandstreifen eingelegt ist und das sehr dünn sein kann. Für alle solche Materialien wird in der vorliegenden Beschreibung der Begriff "Gummifolie" verwendet.According to the invention, the metal edge strips are by means of a to form the zero point of movement rubber film inserted and vulcanized between them firmly connected. It can be a synthetic rubber made of the same or a corresponding one Trade material like the synthetic rubber median strip, which the stretching movements of the Allows dilation element, or the rubber sheet can be made of another, with sheet metal vulcanizable material exist as an additional element between the sheet metal edge strips is inserted and that can be very thin. For all such materials, the present description of the term "rubber sheet" used.
Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels anhand der einzigen Figur der Zeichnung. Further advantages and details of the invention emerge from the following description an embodiment with reference to the single figure of the drawing.
Die Zeichnung zeigt in Schrägansicht die Unterseite eines erfindungsgemäßen Dilatations-elements, wobei einzelne Teile des Elements zur Verdeutlichung des Gesamtaufbaus abgeschnitten dargestellt sind.The drawing shows an oblique view of the underside of a dilatation element according to the invention, with individual parts of the element cut off to illustrate the overall structure are shown.
Das Dilatationselement besteht aus zwei ebenen, etwa rechtwinkligen, länglichen Blechrandstreifen
41 und 42. Mit diesen ist durch Vulkanisation ein Kunstgummimittelstreifen 30
verbunden, wie die Zeichnung zeigt. Der Blechrandstreifen 42 überlappt den anderen Blechrandstreifen
41 an dessen Unterseite so weit, daß an der Oberseite des Elements (in der
Zeichnung die Unterseite) eine längs des Elements durchgehende Überlappung 46 gebildet ist.
Deren Bedeutung ergibt sich aus der oben genannten älteren europäischen Anmeldung (Schutz
des Elements und insbesondere des Kunstgummimittelstreifens 30 gegen Umwelteinflüsse).The dilation element consists of two flat, approximately rectangular, elongated sheet
Die Blechrandstreifen 41 und 42 sind in einem Endbereich 45 fest miteinander dadurch
verbunden, daß in diesem Bereich 45 eine Gummifolie 47 eingelegt ist, mit der einerseits die
Unterseite des Blechrandstreifens 41 und andererseits die Oberseite des Blechrandstreifens 42
vulkanisiert sind. Die Gummifolie 47 erstreckt sich in Längsrichtung des Dilatationselements
von dessen einem Ende her über einen kleinen Teil seiner Länge. Außerdem hat die Gummifolie
47 etwa die Breite des Überlappungsbereichs zwischen den Blechrandstreifen 41 und 42.
Auf diese Weise ist in der Vulkanisierzone der Gummifolie 47 ein Bereich 45 ausgebildet, in
dem die Teile des Dilatationselements praktisch gegeneinander unbeweglich sind (Bewegungsnullpunkt).
Die Dehnbewegungen des Dilatationselements werden an dem entgegengesetzten
Ende eingeleitet, wo also im Einbauzustand an den Kunstgummimittelstreifen 30 die größte
Dehnung des Elements quer zu seiner Längsrichtung auftritt. Wegen der festen Verbindung
im Bereich 45 mittels der Gummifolie 47 ergibt sich hier praktisch keine oder höchstens eine
sehr geringe Querbewegung an dem Dilatationselement, so daß im Bereich 45 praktisch ein
Bewegungsnullpunkt ausgebildet ist, wodurch das ganze Dilatationselement sich nach Art
einer Stimmgabel bewegen kann (Bewegungsnullpunkt im Bereich 45, größte Querbewegung
am entgegengesetzten Ende).The sheet
Zwischen den einander überlappenden Blechrandstreifen 41 und 42 einerseits und dem
Kunstgummimittelstreifen 30 andererseits ist ein nicht vulkanisierbares Abdeckband 48
eingelegt, das schmaler ist als der Kunstgummimittelstreifen 30. Da somit der Kunstgummimittelstreifen
30 nur mit seinen äußeren Längsrändern an den Blechrandstreifen 41 und 42
anliegt, ist nur in diesem Bereich eine Vulkanisation zwischen diesen Bauteilen zur Verbindung
der Blechrandstreifen 41 und 42 miteinander mittels des Kunstgummimittelstreifens 30
möglich. Dagegen verhindert das nicht vulkanisierbare Abdeckband 48 eine Vulkanisation der
Blechrandstreifen 41 und 42 gegenüber dem Kunstgummimittelstreifen 30 in dessen Mittelbereich,
um dort die Dehnfähigkeit des Kunstgummimittelstreifens 30 quer zur Längsrichtung
des Dilatationselements aufrecht zu erhalten bzw. nicht zu beeinträchtigen. Trotzdem dichtet
der Kunstgummimittelstreifen 30 die durch das Dilatationselement überbrückte Bauwerksfuge
vollständig ab.Between the overlapping sheet
In der Zeichnung sind zur Verdeutlichung des Aufbaus der rechte Blechrandstreifen 42, das
Abdeckband 48 und der Kunstgummimittelstreifen 30 abgeschnitten dargestellt. Tatsächlich
erstrecken sich diese Teile über die gleiche Länge wie der linke Blechrandstreifen 41.
Lediglich die einvulkanisierte Gummifolie 47 erstreckt sich von einem Ende des Dilatationselements
her zur Bildung des Bewegungsnullpunkts im Bereich 45 nur über eine verhältnismäßig
kurze Entfernung in Längsrichtung des Dilatationselements.In the drawing, the right sheet
Durch Verwendung einer Gummifolie 47 zum festen Verbinden der Blechrandstreifen 41 und
42 im Bereich 45 des Bewegungsnullpunkts ist es möglich, die Vulkanisationsverbindung in
diesem Bereich gleichzeitig mit dem Vulkanisiervorgang zwischen den Blechrandstreifen 41
und 42 und dem Kunstgummimittelstreifen 30 herzustellen. Das Dilatationselement kann also
in einem einzigen Arbeitsgang aus den Einzelteilen gefertigt werden.By using a
