Definitions

  • the invention relates to an expansion joint tape according to the preamble of claim 1.
  • Such expansion joint tape is known from DE-PS 27 22 139 or CH-PS 606 663.
  • the edge sections are split into two tab-like parts, between which a slot remains, in each of which a side strip is fastened.
  • the underside, flap-like part of the edge sections is longer than the top-side, flap-like part, so that the side strips consisting of fabric or non-woven are exposed on the top of the edge sections.
  • this side strip also extends beyond the outer edge of the lower lobe-like part, that is, transversely away from the central section.
  • the known expansion joint tape already gives rise to corrugations prior to laying, which are extremely cumbersome when laying and gluing the tape.

  • the expansion joint tape according to the invention is characterized in claim 1.
  • This expansion joint tape can be laid and glued smoothly and without the formation of waves, so that it adheres better and more evenly than the previously known tape, which forms folds at the locations of the corrugations when laying and does not adhere perfectly.
  • the expansion joint tape according to the invention is made of the elastic material, in particular synthetic rubber, over its entire width, the deniability of the expansion joint tape is practically limited to its central section due to the reinforcement and / or coating of the surfaces of the edge sections on both sides by means of the side strips. while the edge sections are no longer stretchable due to the side strips applied to them.
  • the expansion joint tape according to the invention can be laid smoothly even in damp or wet conditions at the construction site, since it does not warp on one side or form waves due to its symmetrical edge structure.
  • the side strips consist of a fabric, a fleece or a bituminous mass and are pressed into the edge sections, so that these parts are connected to one another in a particularly firm and laminate-like manner.
  • This pressing can take place, for example, during or after the vulcanization of the edge sections consisting of synthetic rubber.
  • EP-A-0 306 834 describes a multilayer joint bridging material and a method for its production.
  • the material should only be manufactured at the construction site itself. However, it can also be manufactured as a prefabricated component and brought to the construction site as such.
  • the joint bridging material consists of at least three parts: On the edges of a transition (joint), a sealing layer and, if necessary, a rubber-elastic layer are first applied in succession.
  • thermosetting resin a layer of a thermosetting resin
  • thermoplastic or elastomeric plastic that completely covers the transition and the previous layer structure, which in turn is then coated at the edges with a second layer of thermosetting resin, whereupon a further soaked if necessary Cover layer follows.
  • the actual joint bridging material or the prefabricated component thus consists of an elastic central section bridging a building joint in the installed state and two lateral edge sections arranged above and below it which are rigid after the resin has hardened. To build this element, the layers are placed loosely on top of one another and chemically bond with one another. The layers can only be built up and connected in a horizontal plane.
  • thermoplastic or elastomeric plastic layer is itself elastic; however, by embedding them between the two thermosetting resin layers and curing them, the entire layer structure on the side of the joint to be bridged becomes hard and rigid.
  • the joint bridging material thus produced is not flexible; it cannot be laid over edges or corners, and its shape can no longer be changed after production. Manufacturing and installation are time consuming and expensive, and yet the scope is limited.
  • the side strips applied to the wall sections on both sides for the hot laying of the expansion joint tape form a heat shield which is extremely resistant to heating. Even with extremely strong heating, the material applied as a side strip to the edge sections does not burn, since it is reinforced by the elastic material directly underneath, which can dissipate the heat. On the other hand, the elastic material lying under the side strips cannot burn because it is protected by the side strips acting as a heat shield.
  • the side strips made of inextensible and, in particular, soakable material, together with the underlying edge sections made of elastic material form a laminate construction that is extremely resistant to heat. Should the material of the side strips burn to a certain extent, this laminate structure offers a rough surface on the top and the underside without corrugations, which remains level and connects well and tightly to the roof skin.
  • Claim 3 indicates an advantageous possibility for the material selection of the side strips, which results in a good adhesion to the building structure on which the expansion joint tapes are to be attached.
  • the longitudinal edges of the side strips on the central section are stepped in the transverse direction in such a way that they overlap the central section to different degrees on its two surfaces.
  • the elastic material is made rigid only on one surface by the applied side strip, while on the opposite surface the elastic material is exposed, that is to say it can absorb tensile stresses occurring transversely to the longitudinal direction of the band.
  • the gradation of the side stripes forms on the elastic material at the transition from the middle section to the edge sections a transition zone for train initiation. This prevents the side strips from detaching from the elastic material or tearing off the elastic material at the transition point to the side strips.
  • the measure just described can thus significantly extend the life of the expansion joint tape, since the tape can accommodate a much larger number of movement games.
  • This embodiment is particularly advantageous for those cases in which the side strips are glued directly to hard substrates, such as concrete, using a synthetic resin or are only clamped laterally between components. If the side strips are glued with bitumen or if the side strips themselves contain bitumen, the graded formation of the side strips is not so important because the bitumen mass itself is still to a certain extent elastic.
  • the side strips consist of a fabric or fleece, there is a risk that, when the expansion joint tape is installed, moisture will penetrate into the side strips from the central section and be transported through these to the sides transversely to the longitudinal direction of the expansion joint tape. This danger is particularly present if the side strips are not glued or glued clean up to the middle section.
  • the longitudinal edges of the side strips adjoining the central section can be pressed into the elastic edge sections to such an extent that the material of the edge sections is more or less exposed.

In this case, however, a bead can be formed on at least one of the lateral longitudinal edges of the band, which lies laterally on the outside in the production machine. When producing a single expansion joint tape in a correspondingly wide machine, such beads can be present on both longitudinal edges.

Abstract

The expansion joint strip is composed of elastic material, in particular synthetic rubber. It has a central portion (1) for bridging a construction joint and two lateral edge portions (3), to which virtually inextensible side strips (5; 15, 17) are attached as adhesive agents with respect to the construction member. The side strips (5; 15, 17) are applied to both surfaces of the edge portions (3), in particular pressed on, and are flush with their longitudinal edges (7). The side strips (5; 15, 17) can be composed of woven or nonwoven fabric, bituminous masses or a combination of these materials. They can be stepped on the central portion (1) or pressed into the material of the edge portions (3), so that a particularly advantageous transverse-pull introduction and/or sealing is possible there. <IMAGE>

Description

Die Erfindung betrifft ein Dehnfugenband entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to an expansion joint tape according to the preamble of claim 1.

Ein solches Dehnfugenband ist aus der DE-PS 27 22 139 oder CH-PS 606 663 bekannt. Hierbei sind die Randabschnitte in je zwei lappenartige Teile aufgespalten, zwischen denen ein Schlitz verbleibt, in dem jeweils ein Seitenstreifen befestigt ist. Der unterseitige, lappenartige Teil der Randabschnitte ist dabei länger als der oberseitige, lappenartige Teil ausgebildet, so daß an der Oberseite der Randabschnitte der aus Gewebe oder Vlies bestehende Seitenstreifen freiliegt. Darüber hinaus erstreckt sich dieser Seitenstreifen auch über die äußere Kante des unteren lappenartigen Teils hinaus, also quer vom Mittelabschnitt weg frei nach außen. Es ergibt sich somit ein bezüglich Oberseite und Unterseite des Dehnfugenbands unsymmetrischer Aufbau, bei dem an der Oberseite eine größere Fläche des Seitenstreifens freiliegt und bei dem an der Unterseite eine größere Fläche des elastischen Materials bzw. des Kunstgummis freiliegt. Unmittelbar neben dem Mittelabschnitt liegt an den beiden Randabschnitten oben und unten das elastische Material frei.Such expansion joint tape is known from DE-PS 27 22 139 or CH-PS 606 663. Here, the edge sections are split into two tab-like parts, between which a slot remains, in each of which a side strip is fastened. The underside, flap-like part of the edge sections is longer than the top-side, flap-like part, so that the side strips consisting of fabric or non-woven are exposed on the top of the edge sections. In addition, this side strip also extends beyond the outer edge of the lower lobe-like part, that is, transversely away from the central section. This results in an asymmetrical structure with respect to the top and bottom of the expansion joint tape, in which a larger area of the side strip is exposed on the top and in which a larger area of the elastic material or synthetic rubber is exposed on the underside. Immediately next to the middle section, the elastic material is exposed at the two edge sections above and below.

Infolge dieses bezüglich Oberseite und Unterseite unsymmetrischen Aufbaues ergeben sich bei dem bekannten Dehnfugenband schon vor dem Verlegen Wellungen, die beim Verlegen und Verkleben des Bandes ausgesprochen hinderlich sind. Diese Wellungen verstärken sich, wenn, wie auf Baustellen im Freien üblich, die Dehnfugenbänder Feuchtigkeitseinflüssen ausgesetzt sind. Ein einwandfrei dichtes Verkleben der Randabschnitte der Dehnfugenbänder mit der Baukonstruktion ist dann nicht möglich.As a result of this asymmetrical structure with respect to the top and bottom, the known expansion joint tape already gives rise to corrugations prior to laying, which are extremely cumbersome when laying and gluing the tape. These undulations increase when, like on construction sites usual outdoors, the expansion joint tapes are exposed to moisture. It is then not possible to ensure that the edge sections of the expansion joint tapes are properly sealed.

Im modernen Bauwesen werden Flachdächer u.dgl. vorwiegend mit schweißbaren Dachbahnen eingedeckt, die mit heißsiegelfähigen Klebestoffen oder bituminösen Massen getränkt oder beschichtet sind. Zum Verlegen dieser Dachbahnen und zum Einkleben der Dehnfugenbänder zwischen diese Dachbahnen müssen daher die Dachbahnen und/oder die Randabschnitte der Dehnfugenbänder mit starken Brennern erhitz und angeschmolzen werden (sogenanntes Flämmen). Oie erhitzten und angeschmolzenen Bereiche werden dann lediglich zusammengepreßt, um die Klebeverbindung und Abdichtung zu bilden.Flat roofs and the like are used in modern construction. mainly covered with weldable roofing membranes that are soaked or coated with heat-sealable adhesives or bituminous materials. To lay these roofing membranes and to glue the expansion joint tapes between these roofing membranes, the roofing membranes and / or the edge sections of the expansion joint tapes must be heated and melted with strong burners (so-called flaming). The heated and melted areas are then only pressed together to form the adhesive connection and seal.

Bei dem bekannten Dehnfugenband besteht bei dieser Heißverlegung die Gefahr, daß zumindest der seitlich freiliegende äußere Randbereich der Seitenstreifen verbrennt. Darüber hinaus kann auch das elastische Material bzw. der Kunstgummi der Randabschnitte an der Außenseite der oberen und unteren lappenartigen Teile verbrennen. Es ist dann keine einwandfreie Klebverbindung und Abdichtung des Dehnfugenbandes mit der Baukonstruktion möglich.In the known expansion joint tape, there is a risk with this hot laying that at least the laterally exposed outer edge area of the side strips burns. In addition, the elastic material or the synthetic rubber of the edge sections on the outside of the upper and lower tab-like parts can burn. It is then not possible to have a perfect adhesive bond and seal the expansion joint tape with the building construction.

Der Erfindung liegt daher die Aufgabe zugrunde, das Dehnfugenband so auszubilden, daß es sich glatt und ohne Wellungen verlegen und verkleben läßt und daß es gegen ein Erhitzen beim Verlegen unempfindlich ist.The invention is therefore based on the object of designing the expansion joint tape in such a way that it can be laid and glued smoothly and without corrugations and that it is insensitive to heating when laying.

Das erfindungsgemäße Dehnfugenband ist in Anspruch 1 gekennzeichnet.The expansion joint tape according to the invention is characterized in claim 1.

Damit erhält man einen bezüglich Oberseite und Unterseite des Dehnfugenstreifens symmetrischen Aufbau. Dieses Dehnfugenband läßt sich glatt und ohne Wellenbildung verlegen und verkleben, so daß es besser und gleichmäßiger haftet als das vorbekannte Band, das an den Stellen der Wellungen beim Verlegen Falten bildet und nicht einwandfrei klebt. Obwohl das erfindungsgemäße Dehnfugenband über seine ganze Breite aus dem elastischen Material, insbesondere Kunstgummi, besteht, ist durch die beidseitige Armierung und/ oder Beschichtung der Oberflächen der Randabschnitte mittels der Seitenstreifen die Denfähigkeit des Dehnfugenbandes praktisch auf dessen Mittelabschnitt beschränkt, während die Randabschnitte durch die darauf aufgebrachten Seitenstreifen nicht mehr dehnfähig sind. Damit sind nicht nur Wellungen oder Falten an den Randabschnitten vermieden, sondern diese bieten an ihrer Oberseite und ihrer Unterseite rauhe Oberflächen, die sich glatt verlegen und vollflächig einwandfrei verkleben lassen, so daß sich zusammen mit den Dachabdichtungsbahnen ein Sandwich-Aufbau ergibt, durch den die am Dehnfugenband bzw. dessen Mittelabschnitt auftretenden Zugkräfte einwandfrei aufgenommen und übertragen werden können, ohne daß das Dehnfugenband aus dem Schichtaufbau herausreißt. Zusätzliche Befestigungsmittel für die Randbereiche des Dehnfugenbandes, beispielsweise Verschraubungen mit dem Baukörper, sind im allgemeinen nicht nötig.This gives a symmetrical structure with respect to the top and bottom of the expansion joint strip. This expansion joint tape can be laid and glued smoothly and without the formation of waves, so that it adheres better and more evenly than the previously known tape, which forms folds at the locations of the corrugations when laying and does not adhere perfectly. Although the expansion joint tape according to the invention is made of the elastic material, in particular synthetic rubber, over its entire width, the deniability of the expansion joint tape is practically limited to its central section due to the reinforcement and / or coating of the surfaces of the edge sections on both sides by means of the side strips. while the edge sections are no longer stretchable due to the side strips applied to them. Not only are corrugations or folds avoided at the edge sections, but they also offer rough surfaces on their top and bottom that can be laid smoothly and glued over their entire surface, so that together with the roof sealing sheeting, a sandwich construction results, through which the tensile forces occurring on the expansion joint tape or its middle section can be absorbed and transmitted without the expansion joint tape tearing out of the layer structure. Additional fasteners for the edge areas of the expansion joint tape, for example screw connections to the structure, are generally not necessary.

Selbst bei Feuchtigkeit oder Nässe an der Baustelle läßt sich das erfindungsgemäße Dehnfugenband glatt verlegen, da es infolge seines symmetrischen Randaufbaues sich nicht einseitig verzieht oder Wellen bildet.The expansion joint tape according to the invention can be laid smoothly even in damp or wet conditions at the construction site, since it does not warp on one side or form waves due to its symmetrical edge structure.

Dies wird besonders dadurch unterstützt, daß erfindungsgemäß die Seitenstreifen aus einem Gewebe, aus einem Vlies oder aus einer bituminösen Masse bestehen und in die Randabschnitte eingepreßt sind, so daß also diese Teile besonders fest und laminatartig miteinander verbunden sind. Dieses Einpressen kann beispielsweise während oder nach der Vulkanisation der aus Kunstgummi bestehenden Randabschnitte erfolgen.This is particularly supported by the fact that, according to the invention, the side strips consist of a fabric, a fleece or a bituminous mass and are pressed into the edge sections, so that these parts are connected to one another in a particularly firm and laminate-like manner. This pressing can take place, for example, during or after the vulcanization of the edge sections consisting of synthetic rubber.

Die EP-A-0 306 834 beschreibt ein mehrschichtiges Fugenüberbrückungsmaterial und ein Verfahren zu seiner Herstellung. Dabei soll das Material in vielen Fällen erst an der Baustelle selbst hergestellt werden. Es kann jedoch auch als vorgefertigtes Bauelement hergestellt und als solches an die Baustelle gebracht werden. In beiden Fällen besteht das Fugenüberbrückungsmaterial aus mindestens drei Teilen: Auf die Ränder eines Übergangs (Fuge) werden nacheinander zunächst gegebenenfalls eine Versiegelungsschicht und gegebenenfalls eine gummielastische Schicht aufgebracht. Darauf folgt in jedem Fall eine Schicht aus einem Duroplastharz, anschließend eine den Übergang und den vorhergehenden Schichtaufbau vollständig überdeckende Schicht aus einem thermoplastischen oder elastomeren Kunststoff, die ihrerseits an den Rändern anschließend mit einer zweiten Schicht aus Duroplastharz beschichtet wird, worauf ggf. noch eine getränkte Abdeckschicht folgt. Das eigentliche Fugenüberbrückungsmaterial bzw. das vorgefertigte Bauelement besteht also aus einem elastischen, im Einbauzustand eine Baufuge überbrückenden Mittelabschnitt und zwei darüber und darunter angeordneten seitlichen Randabschnitten, die nach dem Aushärten des Harzes starr sind. Zum Aufbau dieses Elements werden die Schichten lose übereinandergelegt und verbinden sich chemisch miteinander. Aufbau und Verbindung der Schichten miteinander können nur in einer waagerechten Ebene erfolgen. Die thermoplastische oder elastomere Kunststoffschicht ist zwar selbst elastisch; durch ihre Einbettung zwischen die beiden Duroplastharzschichten und durch deren Aushärung wird jedoch der gesamte Schichtaufbau seitlich der zu überbrückenden Fuge hart und starr. Das so hergestellte Fugenüberbrückungsmaterial ist also nicht flexibel; es kann nicht über Kanten oder Ecken verlegt werden, und es kann nach der Herstellung nicht mehr in seiner Form verändert werden. Herstellung und Einbau sind also zeitaufwendig und teuer, und trotzdem ist der Anwendungsbereich beschränkt.EP-A-0 306 834 describes a multilayer joint bridging material and a method for its production. In many cases, the material should only be manufactured at the construction site itself. However, it can also be manufactured as a prefabricated component and brought to the construction site as such. In both cases, the joint bridging material consists of at least three parts: On the edges of a transition (joint), a sealing layer and, if necessary, a rubber-elastic layer are first applied in succession. This is followed in each case by a layer of a thermosetting resin, followed by a layer of a thermoplastic or elastomeric plastic that completely covers the transition and the previous layer structure, which in turn is then coated at the edges with a second layer of thermosetting resin, whereupon a further soaked if necessary Cover layer follows. The actual joint bridging material or the prefabricated component thus consists of an elastic central section bridging a building joint in the installed state and two lateral edge sections arranged above and below it which are rigid after the resin has hardened. To build this element, the layers are placed loosely on top of one another and chemically bond with one another. The layers can only be built up and connected in a horizontal plane. The thermoplastic or elastomeric plastic layer is itself elastic; however, by embedding them between the two thermosetting resin layers and curing them, the entire layer structure on the side of the joint to be bridged becomes hard and rigid. The joint bridging material thus produced is not flexible; it cannot be laid over edges or corners, and its shape can no longer be changed after production. Manufacturing and installation are time consuming and expensive, and yet the scope is limited.

Bei dem erfindungsgemäßen Dehnfugenband bilden die auf die Wandabschnitte beidseitig aufgebrachten Seitenstreifen für die Heißverlegung des Dehnfugenbandes ein Hitzeschild, das außerordentlich widerstandsfähig gegen Erhitzung ist. Selbst bei außerordentlich starker Erhitzung verbrennt das als Seitenstreifen auf die Randabschnitte aufgebrachte Material nicht, da es durch das unmittelbar darunter liegende elastische Material verstärkt ist, das die Hitze ableiten kann. Andererseits kann auch das unter den Seitenstreifen liegende elastische Material nicht verbrennen, weil es durch die als Hitzeschild wirkenden Seitenstreifen geschützt ist. Die aus undehnbarem und insbesondere tränkbarem Material bestehenden Seitenstreifen bilden also zusammen mit den darunter liegenden Randabschnitten aus elastischem Material eine gegen Hitze außerordentlich widerstandsfähige Laminatkonstruktion. Sollte dennoch das Material der Seitenstreifen bis zu einem gewissen Grad abbrennen, bietet dieser Laminataufbau an der Oberseite und der Unterseite eine rauhe Oberfläche ohne Wellungen, die eben bleibt und sich gut und dicht mit der Dachhaut verbindet.In the expansion joint tape according to the invention, the side strips applied to the wall sections on both sides for the hot laying of the expansion joint tape form a heat shield which is extremely resistant to heating. Even with extremely strong heating, the material applied as a side strip to the edge sections does not burn, since it is reinforced by the elastic material directly underneath, which can dissipate the heat. On the other hand, the elastic material lying under the side strips cannot burn because it is protected by the side strips acting as a heat shield. The side strips made of inextensible and, in particular, soakable material, together with the underlying edge sections made of elastic material, form a laminate construction that is extremely resistant to heat. Should the material of the side strips burn to a certain extent, this laminate structure offers a rough surface on the top and the underside without corrugations, which remains level and connects well and tightly to the roof skin.

Besonders vorteilhaft ist es, wenn gemäß Anspruch 2 die Seitenstreifen mit den Längskanten der Randabschnitte bündig sind. Es steht dann an den Längskanten kein Material frei nach außen über, also weder das Material der Seitenstreifen noch das Material der Randabschnitte, so daß sich ein einwandfreier seitlicher Abschluß ergibt, dem nicht die Gefahr der Wellenbildung des Bandes anhaftet und der sich sauber und einwandfrei verlegen und verkleben läßt.It when the side strips are flush with the longitudinal edges of the edge sections is particularly advantageous. There is then no material freely projecting outwards at the longitudinal edges, that is to say neither the material of the side strips nor the material of the edge sections, so that there is a perfect lateral closure, which does not adhere to the risk of the band forming waves and which is cleanly and properly laid and can stick together.

Anspruch 3 kennzeichnet eine vorteilhafte Möglichkeit für die Materialwahl der Seitenstreifen, wodurch sich eine gute Haftvermittlung zu der Baukonstruktion ergibt, an der die Dehnfugenbänder anzubringen sind.Claim 3 indicates an advantageous possibility for the material selection of the side strips, which results in a good adhesion to the building structure on which the expansion joint tapes are to be attached.

Wenn die Seitenstreifen an den oberen und unteren Oberflächen des Dehnfugenbandes am Mittelabschnitt mit ihren inneren Seitenrändern unmittelbar übereinanderliegend enden, ist hierdurch eine praktisch starre Einspannstelle des Mittelabschnitts gebildet. Es liegt also praktisch ein sprunghafter Übergang von dem elastischen Mittelabschnitt zu den beiden durch die Seitenstreifen starr gemachten Randabschnitten vor. Bei starker Beanspruchung des Dehnfugenbandes kann diese Stelle als Schwachstelle wirken, d.h. bei zu starker Querdehnung kann sich an dem dem Mittelabschnitt benachbarten Bereich der Randabschnitte die Verbindung zwischen dem elastischen Material und den beidseitigen Seitenstreifen infolge der eingeleiteten Kräfte lösen, oder das elastische Material des Mittelabschnitts kann beim Übergang in die Randabschnitte sogar abreißen.If the side strips on the upper and lower surfaces of the expansion joint tape at the central section end with their inner side edges lying directly one above the other, a practically rigid clamping point of the central section is hereby formed. So there is practically an abrupt transition from the elastic middle section to the two edge sections made rigid by the side strips. If the expansion joint tape is subjected to heavy wear, this point can act as a weak point, i.e. If the transverse stretch is too strong, the connection between the elastic material and the side strips on both sides can come loose at the region of the edge sections adjacent to the central section, or the elastic material of the central section can even tear off during the transition into the edge sections.

Um diese Gefahr zu vermeiden, ist gemäß Anspruch 5 in Weiterbildung der Erfindung vorgesehen, daß die Längsränder der Seitenstreifen am Mittelabschnitt derart in Querrichtung abgestuft sind, daß sie den Mittelabschnitt an seinen beiden Oberflächen unterschiedlich weit überlappen. Dadurch wird im Überlappungsbereich das elastische Material nur an einer Oberfläche durch den aufgebrachten Seitenstreifen starr gemacht, während auf der gegenüberliegenden Oberfläche das elastische Material freiliegt, also noch quer zur Längsrichtung des Bandes auftretende Zugspannungen aufnehmen kann. Die Abstufung der Seitenstreifen bildet also an dem elastischen Material am Übergang vom Mittelabschnitt zu den Randabschnitten eine Übergangszone zur Zugeinleitung. Dadurch ist ein Ablösen der Seitenstreifen von dem elastischen Material oder ein Abreißen des elastischen Materials an der Übergangsstelle zu den Seitenstreifen verhindert.In order to avoid this danger, it is provided according to claim 5 in a development of the invention that the longitudinal edges of the side strips on the central section are stepped in the transverse direction in such a way that they overlap the central section to different degrees on its two surfaces. As a result, in the area of overlap, the elastic material is made rigid only on one surface by the applied side strip, while on the opposite surface the elastic material is exposed, that is to say it can absorb tensile stresses occurring transversely to the longitudinal direction of the band. The gradation of the side stripes forms on the elastic material at the transition from the middle section to the edge sections a transition zone for train initiation. This prevents the side strips from detaching from the elastic material or tearing off the elastic material at the transition point to the side strips.

Durch die soeben geschilderte Maßnahme kann somit die Lebensdauer des Dehnfugenbandes wesentlich verlängert werden, da das Band eine wesentlich größere Zahl von Bewegungsspielen aufnehmen kann. Diese Ausführungsform ist besonders für solche Fälle vorteilhaft, bei denen die Seitenstreifen mittels eines Kunstharzes unmittelbar an harte Unterlagen, wie Beton, angeklebt oder zwischen Bauteilen nur seitlich eingeklemmt werden. Bei einer Verklebung der Seitenstreifen mit Bitumenmasse oder wenn die Seitenstreifen selbst Bitumen enthalten, ist die abgestufte Ausbildung der Seitenstreifen nicht so wesentlich, weil die Bitumenmasse selbst noch bis zu einem gewissen Grad elastisch ist.The measure just described can thus significantly extend the life of the expansion joint tape, since the tape can accommodate a much larger number of movement games. This embodiment is particularly advantageous for those cases in which the side strips are glued directly to hard substrates, such as concrete, using a synthetic resin or are only clamped laterally between components. If the side strips are glued with bitumen or if the side strips themselves contain bitumen, the graded formation of the side strips is not so important because the bitumen mass itself is still to a certain extent elastic.

Wenn die Seitenstreifen aus einem Gewebe oder Vlies bestehen, besteht die Gefahr, daß im eingebauten Zustand des Dehnfugenbandes vom Mittelabschnitt her Feuchtigkeit in die Seitenstreifen eindringt und durch diese quer zur Längsrichtung des Dehnfugenbandes nach den Seiten hin transportiert wird. Diese Gefahr ist insbesondere dann gegeben, wenn die Seitenstreifen nicht sauber bis zum Mittelabschnitt hin eingeklebt oder überklebt werden. Um einen solchen Feuchtigkeitstransport durch die Seitenstreifen hindurch zu unterbinden, können in Weiterbildung der Erfindung gemäß Anspruch 6 die an den Mittelabschnitt angrenzenden Längsränder der Seitenstreifen so weit in die elastischen Randabschnitte eingepreßt werden, daß dort das Material der Randabschnitte mehr oder weniger freiliegt. Dieses elastische Material bildet dann eine Wassersperre oder Feuchtigkeitssperre am Übergang vom Mittelabschnitt zu den Seitenstreifen, so daß in diese keine Feuchtigkeit mehr eindringen kann. Eine solche Wassersperre kann an einer oder an beiden Oberflächen des Dehnfugenbandes vorgesehen sein. Das freiliegende elastische Material der Randabschnitte kann dann auch zu einer unmittelbaren Abdichtung zwischen dem Dehnfugenband und den benachbarten Bauteilen herangezogen werden, indem solche Bauteile unmittelbar an dem Randabschnitt befestigt werden, beispielsweise durch Schrauben, die durch das Dehnfugenband hindurchgeführt werden und an denen keine Feuchtigkeitsbrücken entstehen können, weil solche Befestigungselemente allseitig von dem elastischen Material umgeben sind.If the side strips consist of a fabric or fleece, there is a risk that, when the expansion joint tape is installed, moisture will penetrate into the side strips from the central section and be transported through these to the sides transversely to the longitudinal direction of the expansion joint tape. This danger is particularly present if the side strips are not glued or glued clean up to the middle section. In order to prevent such moisture transport through the side strips, in a further development of the invention, the longitudinal edges of the side strips adjoining the central section can be pressed into the elastic edge sections to such an extent that the material of the edge sections is more or less exposed. This elastic material then forms a water barrier or moisture barrier at the transition from the central section to the side strips, so that moisture can no longer penetrate them. Such a water barrier can be provided on one or both surfaces of the expansion joint tape. The exposed elastic material of the edge sections can then also be used for a direct seal between the expansion joint tape and the adjacent components, in that such components are fastened directly to the edge section, for example by screws which are passed through the expansion joint tape and on which none Moisture bridges can arise because such fasteners are surrounded on all sides by the elastic material.

Eine solche Ausbildung ist vor allem im Grundbau vorteilhaft, wenn also das Dehnfugenband im Bereich des Grundwassers verlegt wird. Die beschriebene Wassersperre kann dann an der Wasserseite des Dehnfugenbandes, beim Grundbau insbesondere an dessen Unterseite, angeordnet werden.Such training is particularly advantageous in foundation engineering, if the expansion joint tape is installed in the area of the groundwater. The water barrier described can then be arranged on the water side of the expansion joint tape, in particular on the underside of the basic construction.

Wenn gemäß Anspruch 7 die infolge der abgestuften Anordnung der Seitenstreifen weiter zum Mittelabschnitt hin vorragenden Längsränder der Seitenstreifen so weit in das elastische Material eingepreßt sind, daß an dieser Stelle das Material der Randabschnitte mindestens teilweise freiliegt, ergibt sich eine besonders einfache Herstellung des Dehnfugenbandes. In der Vulkanisiermaschine können dann die Längsränder der Seitenstreifen derart in das elastische Material eingepreßt werden, daß an einer Oberfläche die Seitenstreifen in Querrichtung geringfügig schräg auslaufend in das elastische Material eingepreßt sind, während auf der gegenüberliegenden Oberfläche durch eine entsprechende Prägeform eine Abstufung des Seitenstreifens am Übergang zum Mittelabschnitt erzielt wird. Mit einfach gestalteten Prägevorrichtungen ergibt sich somit in der Herstellungsmaschine der zweckmäßige gewünschte Querschnitt des Oehnfugenbandes.If, according to claim 7, the longitudinal edges of the side strips projecting further towards the central section due to the graduated arrangement of the side strips are pressed so far into the elastic material that the material of the edge sections is at least partially exposed at this point, the expansion joint tape is particularly easy to produce. In the vulcanizing machine, the longitudinal edges of the side strips can then be pressed into the elastic material in such a way that on one surface the side strips are pressed slightly obliquely into the elastic material in the transverse direction, while on the opposite surface, the side strip is graded at the transition by a corresponding embossing shape to the middle section is achieved. With simply designed embossing devices, the expedient, desired cross section of the expansion joint tape is thus obtained in the production machine.

Eine entsprechende Ausbildung kann gemäß Anspruch 8 an den äußeren seitlichen Längskanten des Dehnfugenbandes vorgenommen werden, so daß auch an diesen äußeren Längskanten eine Wassersperre und eine Abdichtungsmöglichkeit gegeben sind.A corresponding design can be made according to claim 8 on the outer lateral longitudinal edges of the expansion joint tape, so that a water barrier and a sealing option are also provided on these outer longitudinal edges.

Vorzugsweise ist gemäß Anspruch 9 die Dicke der Seitenstreifen an beiden Oberflächen des Dehnfugenbandes unterschiedlich. Für eine günstige Einleitung des Querzuges ist es dabei vorteilhaft, wenn der weiter nach außen abgesetzte Seitenstreifen dicker und damit weniger dehnbar ist als der andere, weiter zum Mittelabschnitt hin vorragende Seitenstreifen, der dann noch eine gewisse Elastizität aufweist. Auch läßt sich ein dünnerer Seitenstreifen, der weiter zum Mittelabschnitt hin vorragt, leichter in das elastische Material des Randstreifens einpressen als ein dickerer Seitenstreifen. Durch die unterschiedliche Dicke der Seitenstreifen an beiden Oberflächen ergeben sich somit in gewissem Maße unterschiedliche Eigenschaften an beiden Oberflächen, wobei trotzdem die eingangs geschilderten Vorteile der Wellungs- und Faltenfreiheit des Dehnfugenbandes und der Hitzeabschirmung beibehalten werden.According to claim 9, the thickness of the side strips on both surfaces of the expansion joint tape is preferably different. For a favorable introduction of the transverse pull, it is advantageous if the side strip which is set further outward is thicker and therefore less stretchable than the other side strip which projects further towards the central section and which then still has a certain elasticity. It is also easier to press a thinner side strip, which protrudes further toward the central section, into the elastic material of the edge strip than a thicker side strip. Due to the different thickness of the side stripes on both Surfaces thus have to a certain extent different properties on both surfaces, while the advantages described at the outset of the fact that the expansion joint tape and the absence of wrinkles and the heat shielding are retained.

Das erfindungsgemäße Dehnfugenband kann derart hergestellt werden, daß in einer entsprechend breiten Maschine mehrere gleichartige Bänder nebeneinander zunächst in einem Stück und in einem Durchlauf gefertigt und anschließend durch Aufschneiden in Längsrichtung voneinander getrennt werden. Dann liegen an den Schnittkanten die Seitenstreifen bündig mit dem dazwischenliegenden Randstreifen. Dabei kann aber gemäß Anspruch 10 an mindestens einer der seitlichen Längskanten des Bandes, die in der Herstellungsmaschine seitlich außen liegt, ein Wulst ausgebildet werden. Bei Herstellung eines einzigen Dehnfugenbandes in einer entsprechend breiten Maschine können solche Wulste an beiden Längsrändern vorhanden sein. Diese Wulste bilden nicht nur einen optisch sauberen seitlichen Abschluß des Dehnfugenbandes, sondern sie dienen zusätzlich als Wassersperre am äußeren Längsrand des Bandes, da hierbei der ggfs. saugfähige Seitenstreifen nicht bis zum äußeren Rand reicht sondern durch den Wulst begrenzt ist.The expansion joint tape according to the invention can be produced in such a way that in a correspondingly wide machine, several similar tapes are produced next to one another first in one piece and in one pass and then separated from one another in the longitudinal direction by cutting. Then the side strips lie flush on the cut edges with the edge strip in between. In this case, however, a bead can be formed on at least one of the lateral longitudinal edges of the band, which lies laterally on the outside in the production machine. When producing a single expansion joint tape in a correspondingly wide machine, such beads can be present on both longitudinal edges. These beads not only form an optically clean side closure of the expansion joint tape, but also serve as a water barrier on the outer longitudinal edge of the tape, since the possibly absorbent side strip does not extend to the outer edge but is limited by the bead.

ist eine schematische Schnittansicht eines dritten Beispiels.
Three embodiments of the invention are described below with reference to the drawing.

shows schematically in oblique view a portion of an expansion joint tape according to the invention;
Fig. 2
shows a schematic end view of another embodiment;
Fig. 3
is a schematic sectional view of a third example.

Gemäß Fig. 1 besteht das Dehnfugenband aus einem Streifen eines elastischen Materials, insbesondere Kunstgummi, der einen Mittelabschnitt 1 sowie zwei damit einstückig verbundene, insbesondere gemeinsam vulkanisierte Randabschnitte 3 aus einem einheitlichen Material aufweist. Auf der Oberseite und auf der Unterseite der Randabschnitte 3 sind Seitenstreifen 5 aus einem im wesentlichen undehnbaren Material angebracht, das mit einem Dichtungsmittel oder einer Klebemasse tränkbar ist, so daß die Seitenstreifen 5 als Haftvermittler zu einer Baukonstruktion dienen, an der das Dehnfugenband angebracht bzw. mit der es verbunden wird. In der Einbaustellung liegt der Mittelabschnitt 1 über der zu überbrückenden Fuge, so daß das Dehnfugenband nicht nur die Fuge überbrückt, sondern an seinen beiden Randabschnitten 3 die unterschiedlichen Bewegungen des Bauwerkes mitmachen kann, wobei sich der Mittelabschnitt 1 mehr oder weniger dehnt, zusammenzieht oder durchwölbt.1, the expansion joint tape consists of a strip of elastic material, in particular synthetic rubber, which has a central section 1 and two integrally vulcanized, in particular vulcanized, edge sections 3 made of a uniform material. On the top and on the underside of the edge portions 3, side strips 5 made of an essentially inextensible material are attached, which can be impregnated with a sealant or an adhesive, so that the side strips 5 as Adhesion promoters are used to build a structure to which the expansion joint tape is attached or to which it is connected. In the installed position, the central section 1 lies above the joint to be bridged, so that the expansion joint tape not only bridges the joint, but can also take part in the different movements of the structure at its two edge sections 3, the central section 1 expanding, contracting or arching more or less .

Die Seitenstreifen 5 sind mit den Längskanten 7 der Randabschnitte 3 bündig. Die Seitenstreifen 5 werden bei der Herstellung des Dehnfugenbandes in die Randabschnitte 3 eingepreßt, beispielsweise während des Vulkanisierens des elastischen Materials bzw. des Kunstgummis des Mittelabschnitts/und der Randabschnitte 3 oder unmittelbar nach diesem Vulkanisieren beim Abkühlen des Bandes.The side strips 5 are flush with the longitudinal edges 7 of the edge sections 3. The side strips 5 are pressed into the edge sections 3 during the production of the expansion joint tape, for example during the vulcanization of the elastic material or the synthetic rubber of the middle section / and the edge sections 3 or immediately after this vulcanization when the tape cools.

Die Seitenstreifen 5 können aus unterschiedlichen Materialien bestehen. Beispielsweise können sie durch ein undehnbares oder oder im wesentlichen undehnbares Gewebe oder ein entsprechendes Vlies gebildet sein, das beidseitig auf die Randabschnitte 3 aufgeklebt oder aufvulkanisiert oder in diese eingebettet ist. Insbesondere kann das Gewebe oder Vlies aus geeigneten Kunststoffen bestehen.The side strips 5 can consist of different materials. For example, they can be formed by an inextensible or or essentially inextensible fabric or a corresponding fleece which is glued or vulcanized onto the edge sections 3 on both sides or embedded in them. In particular, the fabric or fleece can consist of suitable plastics.

Die Seitenstreifen 5 können auch aus einer bituminösen Masse bestehen, die auf die Randabschnitte 3 aufgeklebt oder aufvulkanisiert wird, so daß diese Seitenstreifen selbst Dichtungs- und Klebeeigenschaften haben und sich mit dem gleichartigen Material beispielsweise von bituminösen Dachbahnen gut und dicht verbinden, insbesondere bei der Heißverlegung oder beim Einflämmen.The side strips 5 can also consist of a bituminous mass which is glued or vulcanized onto the edge sections 3, so that these side strips themselves have sealing and adhesive properties and bond well and tightly to the same material, for example of bituminous roofing membranes, particularly when laying hot or when flaming.

Schließlich können die Seitenstreifen 5 aus einer Kombination der beiden vorgenannten Materialien bestehen, also beispielsweise aus einem mit einer bituminösen Masse getränkten Gewebe oder Vlies. In allen Fällen bilden die Seitenstreifen 5 zusammen mit den Randabschnitten 3 einen bezüglich Oberseite und Unterseite des Dehnfugenbandes symmtrischen Aufbau, so daß es praktisch gleichgültig ist, welche Seite des Bandes beim Verlegen nach oben oder nach unten kommt. Es ist auch ein aufrechtstehender oder geneigter Einbau des Dehnfugenbandes möglich.Finally, the side strips 5 can consist of a combination of the two aforementioned materials, that is to say, for example, of a fabric or fleece impregnated with a bituminous mass. In all cases, the side strips 5 together with the edge sections 3 form a structure symmetrical with respect to the top and bottom of the expansion joint tape, so that it is practically irrelevant which side of the tape comes up or down when laying. An upright or inclined installation of the expansion joint tape is also possible.

Die Seitenstreifen 5 werden sandwichartig mit der Baukonstruktion verbunden, beispielsweise zwischen Dachbahnen eingeklebt oder eingeflämmt. Die Adhäsionskraft der Sandwich-Konstruktion ist dabei ohne weiteres größer als die größten auf das elastische Material des Mittelabschnitts 1 wirkenden Zugkräfte, so daß sich auch bei den größten am Band auftretenden Dehnungskräften das Band nicht von der Baukonstruktion lösen kann. Die Dehnung des Bandes ist dabei auf den Mittelabschnitt 1 beschränkt, der bei entsprechender Elastizität des Materials schmal gehalten werden kann. Eine zusätzliche Befestigung des mit den Seitenstreifen armierten Dehnfugenbandes an der sonstigen Baukonstrukion, beispielsweise durch Verschrauben, ist im allgemeinen nicht erforderlich.The side strips 5 are connected to the building structure in a sandwich-like manner, for example glued or flamed between roofing sheets. The adhesive force of the sandwich construction is easily greater than the greatest tensile forces acting on the elastic material of the central section 1, so that the band cannot detach itself from the building construction even with the greatest elongation forces occurring on the band. The stretch of the band is limited to the central section 1, which can be kept narrow with the appropriate elasticity of the material. An additional fastening of the expansion joint tape reinforced with the side strips to the other building construction, for example by screwing, is generally not necessary.

Bei dem Ausführungsbeispiel von Fig. 2 sind zu beiden Seiten des elastischen Mittelabschnitts 1 auf die elastischen Randstreifen 3 Seitenstreifen 15 und 17 unterschiedlicher Gestalt aufgebracht. An der oberen Oberfläche der Randstreifen 3 sind Seitenstreifen 15 aufgebracht, die eine größere Dicke haben als die an der Unterseite der Randstreifen 3 aufgebrachten Seitenstreifen 17. Wie bei dem Ausführungsbeispiel nach Fig 1 bestehen die Seitenstreifen 15 und 17 aus einem im wesentlichen nicht dehnfähigen Material, beispielsweise einem Gewebe oder einem Vlies. Die unteren Seitenstreifen 17 ragen mit ihren inneren Längsrändern 17a weiter zum Mittelabschnitt 1 vor als die oberen Seitenstreifen 15 mit ihren inneren Längsrändern 15a. Zwischen den zusammengehörigen Längsrändern 15a und 17a ergibt sich also eine Abstufung mit der (quer zur Längsrichtung des Dehnfugenbandes gemessenen) Breite a. Dieser Bereich dient zur Einleitung des auf das Dehnfugenband wirkenden Querzuges von den Seitenstreifen 15, 17 in den Mittelbereich 1. Im Bereich des Mittelabschnitts 1 sind die Längsränder 17a der unteren Seitenstreifen 17 bei der Herstellung so weit in die Randabschnitte 3 eingepreßt, daß im Bereich der Längsränder 17a mindestens am Randbereich neben dem Mittelabschnitt 1 das Material der Randabschnitte 3 durch das Material der Seitenstreifen 17 durchdringt und an der Unterseite freiliegt, was aus der Zeichnung nicht ersichtlich ist. Wie in Fig .2 angedeutet ist, verläuft somit das Material der Seitenstreifen 17 von auβen her zum Mittelabschnitt 1 hin in das Material der Randstreifen 3 hinein. Eine entsprechende Ausbildung konnte an beiden Oberflächen des Dehnfugenbandes getroffen sein, also auch für die seitlichen Längsränder 15a der oberen Seitenstreifen 15. Diese Ausbildung kann dadurch erreicht werden, daß in der Vulkanisiermaschine geeignete Werkzeuge vorhanden sind, die die unteren Längsränder 17a dadurch von unten her in die Randstreifen 3 einpressen, daß an der Oberseite des Dehnfugenbandes Gegenhaltewerkzeuge angeordnet sind, die seitlich neben dem Mittelabschnitt 1 eine Abstufung der Längsränder 15a erzeugen, wie in Fig. 2 gezeigt.In the embodiment of FIG. 2, side strips 15 and 17 of different shapes are applied to the elastic edge strips 3 on both sides of the elastic central section 1. Side strips 15 are applied to the upper surface of the edge strips 3, which have a greater thickness than the side strips 17 applied to the underside of the edge strips 3. As in the exemplary embodiment according to FIG. 1, the side strips 15 and 17 consist of a substantially non-stretchable material, for example a fabric or a fleece. The lower side strips 17 project further with their inner longitudinal edges 17a toward the central section 1 than the upper side strips 15 with their inner longitudinal edges 15a. Between the associated longitudinal edges 15a and 17a there is a gradation with the width a (measured transversely to the longitudinal direction of the expansion joint tape). This area serves to initiate the transverse tension acting on the expansion joint tape from the side strips 15, 17 into the central area 1. In the area of the central section 1, the longitudinal edges 17a of the lower side strips 17 are pressed so far into the edge sections 3 during manufacture that in the area of the Longitudinal edges 17a, at least at the edge region next to the central section 1, the material of the edge sections 3 penetrates through the material of the side strips 17 and is exposed on the underside, which is not evident from the drawing. As indicated in FIG. 2, the material of the side strips 17 thus runs from the outside towards the central section 1 into the material of the edge strips 3. A corresponding design could be made on both surfaces of the expansion joint tape, that is to say also for the lateral longitudinal edges 15a of the upper side strips 15. This design can be achieved in that suitable tools are present in the vulcanizing machine, which thereby lower the lower longitudinal edges 17a from below Press here into the edge strips 3 that counter-holding tools are arranged on the upper side of the expansion joint tape, which produce a gradation of the longitudinal edges 15a laterally next to the central section 1, as shown in FIG. 2.

Eine entsprechende Ausbildung kann an den äußeren seitlichen Längskanten 7 und 19 des Dehnfugenbandes vorgenommen sein. Die äußeren Längsränder 17b der Seitenstreifen 17 sind hier von der unteren Oberfläche des Dehnfugenbandes her so weit in die Randabschnitte 3 eingepreßt, daß dort das Material der Randabschnitte 3 mindestens teilweise freiliegt, wobei wiederum die Längsränder 17b von der Mitte des Bandes her nach außen verlaufend mehr und mehr in das elastische Material der Randstreifen 3 eingepreßt sind. Es ergibt sich für die Längsränder 17a und 17b eine in Fig. 2 übertrieben schräg dargestellte Querschnittsform.A corresponding training can be made on the outer lateral longitudinal edges 7 and 19 of the expansion joint tape. The outer longitudinal edges 17b of the side strips 17 are pressed here from the lower surface of the expansion joint tape so far into the edge sections 3 that the material of the edge sections 3 is at least partially exposed there, the longitudinal edges 17b again extending more from the center of the tape and are more pressed into the elastic material of the edge strips 3. For the longitudinal edges 17a and 17b, a cross-sectional shape shown exaggeratedly obliquely in FIG. 2 results.

Analog zu den Abstufungen im Bereich der inneren Längsränder 15a ergibt sich auch eine entsprechende Abstufung für die äußeren Längsränder 15b durch entsprechende Prägewerkzeuge in der Vulkanisierform.Analogous to the gradations in the area of the inner longitudinal edges 15a, there is also a corresponding gradation for the outer longitudinal edges 15b by means of corresponding embossing tools in the vulcanizing mold.

Wie Fig. 2 andeutet, ist die Dicke der Seitenstreifen 17 an der unteren Oberfläche des Dehnfugenbandes geringer als die Dicke der Seitenstreifen 15 an der oberen Oberfläche. Hierdurch wird nicht nur die Ausbildung der in Fig. 2 gezeigten Querschnittsform in der Vulkanisierpresse erleichtert, sondern es ergibt sich auch eine besonders vorteilhafte Ausführung für den Zugeinleitungsbereich a zu beiden Seiten des Mittelabschnitts 1. Weil die Längsränder 17a dünner sind als die Längsränder 15a, wird die Elastizität im Übergangsbereich a mehr oder weniger aufrechterhalten, so daß ein allmählicher Elastizitätsübergang vom Mittelabschnitt 1 zu den durch die Seitenstreifen 15 und 17 abgedeckten Randabschnitten 3 gegeben ist.As indicated in FIG. 2, the thickness of the side strips 17 on the lower surface of the expansion joint tape is less than the thickness of the side strips 15 on the upper surface. This not only facilitates the formation of the cross-sectional shape shown in FIG. 2 in the vulcanizing press, but also results in a particularly advantageous embodiment for the train introduction area a on both sides of the central section 1. Because the longitudinal edges 17a are thinner than the longitudinal edges 15a the elasticity is more or less maintained in the transition region a, so that there is a gradual transition of elasticity from the central section 1 to the edge sections 3 covered by the side strips 15 and 17.

Fig. 2 zeigt schließlich, daß die äußere Längskante 7 des Dehnfugenbandes derart ausgebildet sein kann, daß die äußeren Längsränder 15b und 17b mit dem Außenrand des Randabschnitts 3 bündig sind. Bei einer anderen Ausgestaltung kann an der seitlichen äußeren Längskante 19 ein Wulst 19a vorgesehen sein, der derart abgestuft ist, daß er selbst an der Oberfläche des Dehnfugenbandes freiliegt, und an den sich, in Richtung auf den Mittelabschnitt 1, also in Querrichtung des Fugenbandes, der Seitenstreifen 15 mit seinem Längsrand 15b bündig anschließt, so daß an der Oberfläche ein glatter Übergang von dem Wulst 19a zu dem Längsrand 15b des Seitenstreifens 15 gegeben ist.Fig. 2 shows that the outer longitudinal edge 7 of the expansion joint tape can be designed such that the outer longitudinal edges 15b and 17b are flush with the outer edge of the edge portion 3. In another embodiment, a bead 19a can be provided on the lateral outer longitudinal edge 19 which is stepped in such a way that it is exposed even on the surface of the expansion joint tape and on which, in the direction of the central section 1, that is to say in the transverse direction of the joint tape, the side strip 15 connects flush with its longitudinal edge 15b, so that on the surface there is a smooth transition from the bead 19a to the longitudinal edge 15b of the side strip 15.

Zur Verdeutlichung der Verhältnisse ist insbesondere in Fig. 2 die Dicke des Dehnfugenbandes und der Seitenstreifen im Verhältnis zur Breite übertrieben groß dargestellt.To clarify the situation, the thickness of the expansion joint tape and the side strips in relation to the width is shown in an exaggerated manner, in particular in FIG. 2.

Bei dem Ausführungsbeispiel nach Fig. 3, die nur einen Teil des Querschnittes des Dehnfugenbandes zeigt, ist mindestens an einem der Randabschnitte 3, und zwar mindestens an dessen oberer Oberfläche 3a ein zusätzlicher, über diese Oberfläche 3a erhabener Flächenteil 13 vorgesehen, der aus dem gleichen elastischen Material gebildet ist wie der Randstreifen 3. Ein entsprechender erhabener Flächenteil 13 könnte bei Bedarf auch an der anderen, unteren Oberfläche des Randstreifens 3 vorgesehen sein. Der erhabene Flächenteil 13 bildet eine Dichtungsfläche zur Anlage gegen andere Bauwerksteile und eine Wassersperre gegen das seitliche Durchdringen von Feuchtigkeit quer zur Längsrichtung des Bandes. Hierbei kann insbesondere der Seitenstreifen 5 (Gewebe, Vlies, bituminöse Masse) quer zur Längsrichtung des Dehnfugenbandes über den erhabenen Flächenteil 13 durchlaufen und bei der Herstellung in diesen so weit eingepreßt sein, daß das elastische Material des Randabschnittes 3 an der Oberfläche des Flächenteils 13 mindestens teilweise freiliegt. Damit kann diese freiliegende Oberfläche in besonders günstiger Weise als Abdichtungsfläche und/oder als Wassersperre dienen.In the embodiment according to FIG. 3, which shows only a part of the cross section of the expansion joint tape, at least on one of the edge sections 3, namely at least on its upper surface 3a, an additional surface part 13 raised above this surface 3a is provided, which is made of the same elastic material is formed like the edge strip 3. A corresponding raised surface part 13 could, if necessary, also be provided on the other, lower surface of the edge strip 3. The raised surface part 13 forms a sealing surface for bearing against other structural parts and a water barrier against the lateral penetration of moisture transversely to the longitudinal direction of the band. Here, in particular, the side strip 5 (fabric, fleece, bituminous mass) can run transversely to the longitudinal direction of the expansion joint tape over the raised surface part 13 and be pressed into it so far during manufacture that the elastic material of the edge section 3 at least on the surface of the surface part 13 partially exposed. This exposed surface can thus serve in a particularly advantageous manner as a sealing surface and / or as a water barrier.

Der erhabene Flächenteil 13 kann sich in Streifenform längs des Dehnfugenbandes über dessen ganze Länge erstrecken, bei der Darstellung gemäß Fig. 3 also senkrecht zur Zeichenebene, so daß der erhabene Flächenteil 13 bei der Herstellung des Dehnfugenbandes gemeinsam mit diesem in einem kontinuierlichen Durchlaufverfahren gefertigt werden kann.The raised surface part 13 can extend in strip form along the expansion joint tape over its entire length, in the illustration according to FIG. 3 so perpendicular to the plane of the drawing, so that the raised surface part 13 can be produced together with the same in a continuous continuous process during the production of the expansion joint tape .

Fig. 3 zeigt eine praktische Anwendung des Dehnfugenstreifens. An einer Baustelle werden im Bereich des erhabenen Flächenteils 13 eines oder mehrere Löcher 14 senkrecht zur Ebene des Dehnfugenbandes durch den Randabschnitt 3 und dessen Seitenstreifen 5 hindurch angebracht. Da sich der erhabene Flächenteil 13 über die Länge des Dehnfugenbandes erstreckt, können die Löcher 14 an jeder beliebigen bzw. erforderlichen Stelle angebracht werden. Durch jedes Loch 14 kann ein Anker 21 eingesetzt werden, der in die Unterkonstruktion unterhalb des Dehnfugenbandes eingreift und dort befestigt wird, beispielsweise eingeschraubt oder einbetoniert wird. Der Anker 21 trägt einen Ankerteller 23 mit einer an dessen Unterseite anvulkanisierten Gummiauflage 25 (Kunstgummi oder anderes elastisches Material). Über den Anker 21 kann ein weiteres Bauteil, beispielsweise ein Winkelblech 27, aufgesetzt und mittels einer Mutter 29 festgeschraubt werden. Beim Anziehen der Mutter 29 drückt die Gummiauflage 25 des Ankertellers 23 auf den erhabenen Flächenteil 13 des Randstreifens 3 und bewirkt somit an dieser Stelle eine Feuchtigkeitsabdichtung. Das Winkelblech 27 ist nur als Beispiel gezeigt. Es können hier beliebige andere Baukonstruktionen befestigt werden.Fig. 3 shows a practical application of the expansion joint strip. At a construction site, one or more holes 14 are made perpendicular to the plane of the expansion joint tape in the area of the raised surface part 13 through the edge section 3 and its side strips 5. Since the raised surface part 13 extends over the length of the expansion joint tape, the holes can 14 can be attached at any or required location. An anchor 21 can be inserted through each hole 14, which engages in the substructure below the expansion joint tape and is fastened there, for example screwed in or concreted in. The armature 21 carries an anchor plate 23 with a rubber pad 25 vulcanized onto its underside (synthetic rubber or other elastic material). A further component, for example an angle plate 27, can be placed over the anchor 21 and screwed tight by means of a nut 29. When the nut 29 is tightened, the rubber pad 25 of the anchor plate 23 presses on the raised surface part 13 of the edge strip 3 and thus effects a moisture seal at this point. The angle plate 27 is only shown as an example. Any other construction can be attached here.

Die Abdichtung zwischen dem erhabenen Flächenteil 13 und der Gummiauflage 25 am Anker 23 kann verbessert werden, wenn diese beiden Teile 13 und 25 miteinander verklebt oder miteinander kalt vulkanisiert werden. In jedem Fall erfolgt durch die aneinander anliegenden Teile 13 und 25 eine Abdichtung im Bereich des Ankers 21.The seal between the raised surface part 13 and the rubber pad 25 on the armature 23 can be improved if these two parts 13 and 25 are glued together or cold vulcanized together. In any case, the abutting parts 13 and 25 provide a seal in the area of the armature 21.
