Abstract

An elastomeric sectional strip, for sealing an expansion joint on a building. Each edge of the strip is thickened for engagement in a corresponding one of a pair of grooves bordering the joint edges and is characterized by a three-point mounting of its thickened edge region inside each of said grooves. Each three point mounting is constituted by: (a) a bulge on an upper side of the edge region, in which case said bulge is located inside said groove adjacent its opening; (b) a shoulder projecting in the form of a wedge into said groove in the opposite direction to the insertion direction on an underside of said edge region, in which case after complete insertion, said shoulder bears against a corresponding stop face of the groove and (c) a camber on said upper side of said edge region close to its outer end.

Description

Die Erfindung betrifft ein elastomeres.Profilband zum Abdichten von bauwerkseitigen Dehnungsfugen, dessen Ränder für den Anschluß in entsprechenden Nuten der Fugenränder jeweils verdickt ausgebildet sind.The invention relates to an elastomeric profile strip for sealing structural expansion joints, the edges of which are thickened for connection in corresponding grooves in the joint edges.

Derartige Profilbänder sind in mannigfacher Ausführung bekannt. Sie unterscheiden sich u.a. hinsichtlich ihres Faltprinzips, der Befestigungsart, der verwendeten Materialien od. dgl. Für ihre Ausgestaltung ist beispielsweise auch das Anwendungsgebiet von wesentlichem Einfluss; ein Profilband in Dehnungsfugen von Verkehrswegen unterliegt selbstverständlich gänzlich anderen Anforderungen als ein für dieAbdichtung von Dehnungsfugen im Hochbau vorgesehenes Profilband.Such profile tapes are known in manifold designs. They differ among other things with regard to their folding principle, the type of fastening, the materials used or the like. For their configuration, for example, the field of application is also of considerable influence; A profile tape in expansion joints of traffic routes is of course subject to entirely different requirements than a profile tape intended for sealing expansion joints in building construction.

Ein bekanntes Profilband für Dehnungsfugen (CH-PS 520 823) besitzt als Hohlprofil ausgebildete Befestigungsränder. Die Hohlprofile lassen sich gut zusammenfalten, sind jedoch schwierig einzuführen und unzureichend gegen Herausreissen gesichert.A known profile tape for expansion joints (CH-PS 520 823) has fastening edges designed as a hollow profile. The hollow profiles can be folded up easily, but are difficult to insert and insufficiently secured against tearing out.

Bei einem anderen bekannten Profilband zum Abdichten von Dehnungsfugen (DE-GM 6 605 223) sind die Befestigungsränder mit widerhakenähnlichen Vorsprüngen versehen, die sichin einem fugenrandseitigen Nutenhohlraum verspreizen. Derartige Profilbänder lassen sich nur schwer montieren und zwar wegen der damit verbundenen Quetsch- und Verformungsarbeit. Diese Arbeit - wird häufig noch dadurch erschwert, daß in engen Fugen die seitlichen Nuten für die Aufnahme der Befestigungsränder der Profilbänder nur schwer zugänglich sind.In another known profile tape for sealing expansion joints (DE-GM 6 605 223), the fastening edges are provided with barb-like projections which spread out in a groove cavity on the edge of the joint. Such profile strips are difficult to assemble because of the squeezing and deformation work involved. This work - is often made more difficult by the fact that in narrow joints the lateral grooves for receiving the fastening edges of the profile strips are difficult to access.

An einem anderen bekannten Profilband (DE-OS 30 47 904) sind zur Erleichterung der Montage an den freien Enden der Befestigungsränder abwinkelbare Leisten angeformt. Diese Leisten legen sich beim Einschieben der Befestigungsränder in die entsprechenden Nuten gegen das Bandprofil im Bereich der Befestigungsränder an und verspreizen sich nach dem vollständigen Einschieben gegen Stützflächen, ausgebildet an entsprechenden Hohlraumerweiterungen der Befestigungsnuten. Andererseits verhindern die genannten Leisten eine wünschenswerte Verdickung der Befestigungsränder.On another known profile tape (DE-OS 30 47 904), bendable strips are molded onto the free ends of the fastening edges to facilitate assembly. When inserting the fastening edges into the corresponding grooves, these strips lie against the band profile in the region of the fastening edges and, after being completely inserted, expand against supporting surfaces formed on corresponding cavity extensions of the fastening grooves. On the other hand, the mentioned strips prevent a desirable thickening of the fastening edges.

Schließlich gibt es noch Profilbänder (US 3 888 599) bei denen die Randverdickung unter Ausnutzung der Formelastizität eines Vollgummiteils in die entsprechende Befestigungsnut eingequetscht wird. Auch hier ist die Montage erschwert und die Sicherung egen Herausreissen gering.Finally, there are profile strips (US 3 888 599) in which the edge thickening takes advantage of the formula elasticity of a solid rubber part in the corresponding Mounting groove is squeezed. Here, too, the assembly is difficult and the protection against tearing out is low.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Profilband mit erhöhter Sicherheit gegen Zugbeanspruchung zu schaffen, das sich mit geringem Aufwand montieren lässt, trotzdem aber eine einfache, für das Extrusionsverfahren besonders vorteilhafte Profilierung aufweist.The present invention has for its object to provide a profile tape with increased security against tensile stress, which can be assembled with little effort, but still has a simple, particularly advantageous for the extrusion process profiling.

Diese Aufgabe wird erfindungsgemäß an einem Profilband der eingangs genannten Art dadurch gelöst, daß

  • a) eine Erhöhung an der Oberseite des Randbereichs, wobei die Erhöhung innerhalb der Nut benachbart deren Öffnung angeordnet ist,
  • b) einen entgegen der Einschubrichtung (F1) in die Nut keilförmig vorspringenden Ansatz an der Unterseite des Randbereichs, wobei sich der Ansatz nach dem vollständigen Einschieben gegen eine entsprechende Rastfläche der Nut abstützt und
  • c) eine Auswölbung an der Oberseite des Randbereichs an oder nahe dessen äusseren Ende.
This object is achieved in a profile strip of the type mentioned in that
  • a) an elevation at the top of the edge region, the elevation being arranged within the groove adjacent to its opening,
  • b) a projection protruding in a wedge shape against the direction of insertion (F1) into the groove on the underside of the edge region, the projection being supported against a corresponding latching surface of the groove after the insertion is complete and
  • c) a bulge on the top of the edge area at or near its outer end.

Gemäß Merkmal a) dient die obere Erhöhung als Gegenlager und als Dichtlippe, d.h. bei vollständig in die Befestigungsnut eingeschobenem Randbereich befindet sich die Erhöhung im Inneren der Nut, wo sie an die benachbarte Innenwand dichtend angedrückt wird. Außerdem können die beiderseitigen Erhöhungen zur Montageerleichterung dadurch beitragen, daß sie Ansatzflächen für Montagewerkzeuge bilden (Fig. 4).According to feature a), the upper elevation serves as a counter bearing and as a sealing lip, i.e. when the edge region is pushed completely into the fastening groove, the elevation is located inside the groove, where it is pressed tightly against the adjacent inner wall. In addition, the increases on both sides can make assembly easier by forming attachment surfaces for assembly tools (FIG. 4).

Der an der Unterseite vorhandene Vorsprung dient der Begrenzung des Einschiebewegs bei der Montage des Profilbands; auf diese Weise ist eine genaue Begrenzung der Nutentiefe nicht erforderlich.The protrusion on the underside serves to limit the insertion path when mounting the profile strip; in this way an exact limitation of the groove depth is not necessary.

Gemäß Merkmal b) dient der nach unten vorspringende keilförmige Ansatz der Sicherung des Randbereichs des Bandprofils gegen Ausziehen aus der entsprechenden Befestigungsnut. In Zusammenwirken mit den Merkmalen a) und c) genügt es, diesen Ansatz verhältnismäßig schwach auszubilden, so daß die Verformungsarbeit bei der Montage gering ist. Die Keilform des Ansatzes erleichtert den Einbau. Eine zur Dehnungsfuge hinweisende Stützfläche des Ansatzes kommt bei vollständig eingeschobenem Randbereich gegen eine entsprechende Rastfläche der Nut, ausgebildet durch eine innere Nuterweiterung zur Anlage.According to feature b), the downwardly projecting wedge-shaped attachment serves to secure the edge region of the band profile against being pulled out of the corresponding fastening groove. In cooperation with the features a) and c), it is sufficient to make this approach relatively weak, so that the deformation work during assembly is low. The wedge shape of the approach facilitates installation. A support surface of the extension, pointing towards the expansion joint, comes into contact with a corresponding latching surface of the groove when the edge region is fully inserted, formed by an internal groove extension.

Das Zusammenwirken zwischen den Merkmalen a), b) und c) geschieht in der Weise, daß in der entgültigen Montagestellung die zur Profilbandoberseite hin vorgesehene Auswölbung am äußeren Ende des Randbereichs so stark gegen die benachbarte Nutenwand aufläuft, daß der äußere Randbereich insgesamt von der Nutenwand weg umgelenkt wird, was man auch mit einerArt Nickbewegung des äußeren Randbereichs des Profilbands umschreiben könnte. Infolge der beschriebenen , unter entsprechender Materialverspannung erzeugten Umlenkung des äußeren Randbereichs wird der keilförmige Ansatz an dessen Unterseite verstärkt hinter die entsprechende Rastfläche der Nut im Sinne einer Erhöhung der Rastwirkung angedrückt. Dabei wirkt die Erhöhung auf der Profilbandoberseite (Dichtlippe) als Gegenlager für die Umlenkung des äußeren Randbereiches. Der Einbauzustand ist also gekennzeichnet durch eine verspannte Dreipunktlagerung zwischen den Abstützpunkten von Auswölbung, Erhöhung und keilförmigem Ansatz (Fig. 3).The interaction between the features a), b ) and c) takes place in such a way that, in the final assembly position, the bulge provided towards the top of the profiled tape at the outer end of the edge area runs so strongly against the adjacent groove wall that the outer edge area as a whole extends from the groove wall is deflected away, which could also be described with a kind of pitching movement of the outer edge area of the profiled tape. As a result of the described deflection of the outer edge region, which is produced with appropriate material bracing, the wedge-shaped attachment on its underside is increasingly pressed behind the corresponding latching surface of the groove in order to increase the latching effect. The increase on the top of the profile strip (sealing lip) acts as a counter bearing for the deflection of the outer edge area. The installation state is therefore characterized by a braced three-point bearing between the support points of bulge, elevation and wedge-shaped shoulder (Fig. 3).

Die auf der Gegenseite der Auswölbung vorhandene Hohlkehle bzw. eine entsprechende konkave Form des äußeren Randbereichs ist notwendig, um diesen bei Beginn des Einführens in die Befestigungsnut entsprechend umzulenken, was sich unter Zuhilfenahme eines Montagewerkzeugs besonders vorteilhaft auswirkt. Die Hohlkehle erlaubt ferner trotz der kopfartigen Verdickung des äußeren Randbereichs dessen zwangloses Einführen durch den verengten äußeren Nutabschnitt und dient als Rastfläche für das Profilband, wenn es in den Fugenspalt eingelegt wird (Fig. 4). Sebstverständlih ist im Rahmen der Ertindung eine an das Profilband, insbesondere dessen Randbereich angepaßte bestimmte Ausbildung der Befestigungsnut wesentlich. Hierzu schlägt die Erfindung vor, daß die Nuten jeweils einen an die Querschnittsform der verdickten Randbereiche angepaßten Hohlquerschnitt aufweisen, der jedoch die obere Auswölbung des Profilbands nicht aufweist und dessen Höhe im Eingangsbereich geringer ist als die Profildicke des Randbereichs, gemessen durch den unteren Ansatz.The fillet on the opposite side of the bulge or a corresponding concave shape of the outer edge region is necessary in order to deflect it accordingly at the start of insertion into the fastening groove, which has a particularly advantageous effect with the aid of an assembly tool. Despite the head-like thickening of the outer edge area, the fillet also allows it to be inserted freely through the narrowed outer groove section and serves as a locking surface for the profile strip when it is inserted into the joint gap (FIG. 4). Sebstverständlih is within the E rtindung a shape adapted to the profile strip, in particular the edge region forming the attachment groove certain essential. To this end, the invention proposes that the grooves each have a hollow cross section which is adapted to the cross-sectional shape of the thickened edge regions, but which does not have the upper bulge of the profiled strip and whose height in the entrance region is less than the profile thickness of the edge region, measured by the lower shoulder.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert. Es zeigt

  • Fig. 1 einen Querschnitt durch die linke Hälfte eines Profilbands außerhalb der Befestigungsnut,
  • Fig. 2 den Randbereich des Profilbands gemäß Fig. 1 halb in die Befestigungsnut eingeschoben,
  • Fig. 3 den Randbereich des Profilbands gemäß den Figuren 1 und 2, vollständig in die Befestigungsnut eingeschoben und
  • Fig. 4 einen vollständigen Profilbandquerschnitt in einer Lage unmittelbar vor Beginn des Montagevorgangs.
An embodiment of the invention is explained below with reference to the drawing. It shows
  • 1 shows a cross section through the left half of a profile strip outside the fastening groove,
  • 2 the edge area of the profile strip according to FIG. 1 half inserted into the fastening groove,
  • Fig. 3, the edge region of the profile strip according to Figures 1 and 2, fully inserted into the mounting groove and
  • Fig. 4 shows a complete profile cross section in a position immediately before the start of the assembly process.

In den Figuren 1 bis 3 ist das Montieren in drei Phasen dargestellt, wobei das Profilband selbst nur jeweils äs Teilquerschnit nämlich in Fig. 1 als Halbschnitt und in den Figuren 2 und 3 jeweils lediglich ein Querschnitt durch den Randbereich dargestellt ist. In Fig. 4 hingegen sind die beiden eine Dehnungsfuge 2 begrenzenden Fugenränder 3, 4 sowie zwischen diesen das vollständige Profilband 1 in der Ausgangsstelleung für die Montage, dargestellt.In FIGS. 1 to 3, the assembly is shown in three phases, the profile strip itself being shown only as a partial cross-section, namely in FIG. 1 as a half section and in FIGS. 2 and 3 only a cross section through the edge region. 4, on the other hand, shows the two joint edges 3, 4 delimiting an expansion joint 2 and between them the complete profile strip 1 in the starting position for assembly.

In dem hier gewählten Ausführungsbeispiel sind die Fugenränder 3,4 im wesentlichen als U-Profile dargestellt, deren Schenkel eine Nut 5 für den Anschluß eines Randbereichs.6 eines Profilbands 1 bgrenzen. Die Nut 5 besitzt einen verengten Eintrittsquerschnitt bzw. im Inneren einen erweiterten Nutenhohlraum 15, der u.a. durch eine nach innen weisende Rastfläche 7 des unteren Schenkels des U-Profils begrenzt ist. Jeder Randbereich des Profilbands 1 umfaßt an der Oberseite eine Erhöhung 8 sowie eine Auswölbung 9 am äußeren Ende des Randbereichs 6.In the exemplary embodiment selected here, the joint edges 3, 4 are shown essentially as U-profiles, the legs of which delimit a groove 5 for connecting an edge region 6 of a profile strip 1. The groove 5 has a narrowed inlet cross-section or an enlarged groove cavity 15 inside, which is delimited, inter alia, by an inwardly facing latching surface 7 of the lower leg of the U-profile. Each edge region of the profiled strip 1 comprises an elevation 8 on the upper side and a bulge 9 at the outer end of the edge region 6.

An der Unterseite umfaßt der Randbereich 6 etwa gegenüber der genannten Erhöhung 8 einen Vorsprung 10 sowie einen keilförmigen Ansatz 11. Gegenüber der Auswölbung 9 besitzt die Profilunterseite eine Hohlkehle 12. Im übrigenist der Profilquerschnitt im Randbereich 6 etwas dicker als im übrigen Querschnittsbereich des Profilbands 1. Die Achse a verläuft vertikal durch die mittlere Umbiegung 13 des Profilbands 1.On the underside, the edge area 6 comprises a protrusion 10 and a wedge-shaped projection 11, as compared to the elevation 8 mentioned. Compared to the bulge 9, the underside of the profile has a groove 12. In addition, the profile cross section in the edge area 6 is somewhat thicker than in the rest of the cross-sectional area of the profile strip 1. The axis a runs vertically through the central bend 13 of the profile strip 1.

Gemäß Fig. 2 ist der Randabschnitt 6 etwa zur Hälfte in das Innere der Nut 5 eingeschoben. Im Bereich des verengten Eintrittsquerschnitts legt sich der an der Bandunterseite vorgesehene keilförmige Ansatz 11 beim Einschieben gem.Pfeil F1 an die Unterseite des Profilbands an. Das Einschieben kann durch ein in Richtung des Pfeils P1 an der Erhöhung 8 angesetztes Werkzeug, welches selbst nicht dargestellt ist, erfolgen.2, the edge section 6 is inserted approximately half into the interior of the groove 5. In the area of the narrowed inlet cross-section, the wedge-shaped shoulder 11 provided on the underside of the band lies against the underside of the profiled band when pushed in according to arrow F1. The insertion can be carried out by a tool attached to the elevation 8 in the direction of the arrow P1, which tool itself is not shown.

Gemäß Fig. 3 ist der Randbereich 6 vollkommen in die Nut 5 eingeschoben. Die Erhöhung 8 liegt dabei an der zugeordneten Wand der Nut 5 an. Die Erhöhung 8 bildet das Gegenlager und eine Dichtlippe gegen das Eintreten von Wasser. Der Nutenhohlraum 15 ist so bemessen, daß bei vollständig eingeschobenem Randbereich 6 die Auswölbung 9 durch die Wand der Nut nach unten abgelenkt, der keilförmige Ansatz 11 somit fest gegen die Rastfläche 7 des Nutenhohlraums 15 angedrückt wird. Der untere Vorsprung 10 bildet gewissermaßen einen Anschlg gegen zu weites Einschieben des Randbereichs 6 in die Nut 5. An der Oberseite des vollständig eingeschobenen Randbereichs 6 ergibt sich ein Ausgleichsraum 14 zum Ausgleich von Toleranzabweichungen. Die Lage der Auswölbung 9 und der Erhöhung 8 relativ zum keilförmigen Ansatz 11 ist durch die Hebelarme h1 und h2 gekennzeichnet.3, the edge region 6 is completely inserted into the groove 5. The elevation 8 lies against the assigned wall of the groove 5. The increase 8 forms the counter bearing and a sealing lip against the ingress of water. The groove cavity 15 is dimensioned so that the bulge 9 through when the edge region 6 is fully inserted the wall of the groove is deflected downward, the wedge-shaped projection 11 is thus pressed firmly against the locking surface 7 of the groove cavity 15. The lower projection 10 forms, so to speak, a stop against the edge region 6 being pushed too far into the groove 5. On the upper side of the completely inserted edge region 6 there is a compensation space 14 for compensating for tolerance deviations. The position of the bulge 9 and the elevation 8 relative to the wedge-shaped extension 11 is characterized by the lever arms h 1 and h 2 .

In Zusammenhang mit Fig. 3 wird deutlich, daß der mit dem beschriebenen Profilband erzielte feste Halt des in die Nut 5 eingeschobenen Randbereichs 6 wesentlich durch eine gesteuerte Deformation des Randbereichs 6 im Inneren der Nut 5 bewirkt wird. Infolge der gemäß Pfeil F2 nach unten gerichteten Ablenkung des äußeren, die Auswölbung 9 aufweisenden Endes des Randbereichs 6 kommt es zu einer Verspreizung des unteren Ansatzes 11 gegen die Rastfläche 7 der Nutwandung. Damit wird der Gesamtquerschnitt des Randbereichs 6 einschließlich des Ansatzes 7 bei Zugbeanspruchung wirksam, d.h. die Zugbelastung kann entsprechend groß sein.In connection with FIG. 3, it is clear that the firm hold of the edge region 6 inserted into the groove 5, which is achieved with the profile strip described, is essentially brought about by a controlled deformation of the edge region 6 in the interior of the groove 5. As a result of the downward deflection of the outer end of the edge region 6, which has the bulge 9, according to the arrow F2, the lower shoulder 11 is spread out against the latching surface 7 of the groove wall. The total cross section of the edge region 6 is thus inclusive the approach 7 effective in tensile stress, ie the tensile load can be correspondingly large.

Fig. 4 zeigt schematisch ein Montagewerkzeug 16 mit ausklappenden Flügeln 17 am unteren Ende. Wird das Montagewerkzeug gemäß Pfeil F3 angehoben, so unterfangen die Enden der Flügel 17 die in der gezeichneten Lage des Profilbands nach innen gerichteten Erhöhungen 8, so daß das Profilband insgesamt angehoben wird. Die Hohlkehlen 12 an der Unterseite der Randbereiche 6 legen sich an den unteren Schenkel des jeweiligen Randprofils 3, 4 an und bewirken auf diese Weise ein Umlenken der Enden jedes Randbereichs gemäß Pfeil F4 in das Innere der Nuten 5 hinein. Nach erfolgter Umlenkung in die horizontale Läge der Randbereiche 6 werden diese ebenfalls mit einem Wemzeug durch weiteres Andrücken an die Erhöhungen 8 in Richtung des Pfeiles F1 (Fig. 2) vollständig in die Nuten 5 eingeschoben.Fig. 4 shows schematically an assembly tool 16 with flaps 17 at the lower end. If the assembly tool is raised in accordance with arrow F3, the ends of the wings 17 undercut the elevations 8 which are directed inwards in the position of the profiled strip, so that the profiled strip is lifted as a whole. The fillets 12 on the underside of the edge regions 6 lie against the lower leg of the respective edge profile 3, 4 and in this way bring about a deflection of the ends of each edge region according to arrow F4 into the interior of the grooves 5. After deflection into the horizontal position of the edge regions 6, these are also completely pushed into the grooves 5 with a tool by further pressing on the elevations 8 in the direction of the arrow F1 (FIG. 2).
