Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstel lung von innen liegenden Fugenbändern aus extru dierbarem, elastischem Werkstoff mit quer zur Längsrichtung eingefügten Armierungsstäben und die nach dem Verfahren hergestellten Fugenbänder.The invention relates to a method of manufacture inner joint tapes made of extru dable, elastic material with across Reinforcing bars inserted in the longitudinal direction and the Joint tapes produced by the process.
Durch die DE-PS 29 26 581 ist ein Verfahren zur Herstellung derartiger Fugenbänder bekannt gewor den, bei dem der zu extrudierende Werkstoff für ein Fugenband in zwei vertikal voneinander getrennte Teilströme aufgeteilt wird. In die Trennwand zwi schen den Teilströmen wird, abgeschirmt gegen die Teilströme, nacheinander je ein Armierungselement eingeschoben, in einem horizontalen Stapel bis zur Zone der Zusammenführung der beiden Teilströme geführt und in Abständen einzeln zwischen die Teilströme eingefügt.DE-PS 29 26 581 is a method for Production of such joint tapes has become known the one where the material to be extruded for a Joint tape in two vertically separated Partial streams is divided. In the partition between the partial flows is shielded against the Partial flows, one reinforcement element each inserted in a horizontal stack up to Zone of the merging of the two partial flows guided and spaced individually between the Partial streams inserted.
Die extrudierte Masse der Teilströme umschließt die eingefügten Stäbe unter der Wirkung des dort herr schenden niedrigen Druckes und des von außen auf die Teilströme wirkenden hohen Druckes.The extruded mass of the partial flows encloses the inserted rods under the effect of mister there low pressure and from the outside the partial flows of high pressure.
Diese geschilderte Arbeitsweise gewährleistet zwar eine kontinuierliche Produktion von quer armierten Fugenprofilen.This method of operation guarantees a continuous production of cross-armored Joint profiles.
Sie gewährleistet diese Funktion aber nur bei Verwendung von Armierungsstäben mit vorzugsweise rundem Querschnitt.It only guarantees this function for Use of reinforcing bars with preferably round cross section.
Bei anderen Profilen, z. B. flachen Stahlprofilen, kann der notwendige Unterdruck in der Zone des Umschließens der Armierungsstäbe durch den Kunst stoff nicht zuverlässig gesichert werden. With other profiles, e.g. B. flat steel profiles, can the necessary negative pressure in the zone of Enclosing the reinforcing bars through art cannot be reliably secured.
Runde Armierungsstäbe stoßen aber leichter durch den Werkstoff des Fugenbandes. Damit das vermieden wird, ist es notwendig, dieselben an ihren Enden abzurunden oder mit Fasen zu versehen. Das erfor dert einen hohen Arbeitsaufwand.Round reinforcing bars penetrate more easily the material of the joint tape. So that avoided it is necessary to end them at the same round off or bevelled. The requ a lot of work.
Verzichtet man auf diesen kostenintensiven Arbeits gang, kann der Grat am Ende dieser Stäbe auch die Dichtungen für die Sicherung des Unterdruckes beim Extrudieren zerstören.If you do without this costly work gang, the ridge at the end of these rods can also be the Seals for securing the vacuum at Destroy extrude.
Die nachteiligen Wirkungen dieser scharfkantigen Enden der Armierungsstäbe im Fugenband werden noch dadurch verstärkt, daß der der Formgebung folgende Schrumpfvorgang den Kunststoff über diese Kanten spannt und das Durchstoßen fördert.The adverse effects of this sharp edged The ends of the reinforcing bars in the joint tape will still be reinforced by the fact that the shape follows Shrink the plastic over these edges tense and encourages puncture.
Bei durchstoßenen Fugenbändern sind die Armierungs stäbe beim Transport zur Baustelle, beim Einfügen in die Betonwände und auch im eingesetzten Ge brauchszustand der Luft und der Feuchtigkeit ausge setzt, beginnen zu rosten und beeinträchtigen so die Funktion des Fugenbandes in nachteiliger Weise.When the joint tapes are pierced, the reinforcements are rods during transport to the construction site, when inserting in the concrete walls and also in the used Ge condition of the air and moisture sets, start to rust and so impair the function of the joint tape in a disadvantageous manner.
Ungehärtete Drähte können sich, verwendet als Armierungsstäbe, auch beim Eingießen in den Beton verbiegen. Eine Korrektur ist dann nicht mehr möglich. So eingegossene Fugenbänder erfüllen ihre Funktion nicht mehr.Unhardened wires can become used as Reinforcing bars, even when pouring into the concrete bend. A correction is then no longer possible. Joint tapes cast in this way fulfill their requirements Function no longer.
Durch die DE-PS 30 11 225 ist ein ähnliches Verfah ren zur Herstellung dieser Fugenbänder bekannt geworden. Bei diesem Verfahren werden zwischen zwei horizontalen Platten quer zum entstehenden Fugen band Armierungsstäbe in Form flacher, platinenför miger Elemente zugeführt. Oberhalb und unterhalb dieser Platten wird über eine schräge Zuführung das zu extrudierende Material unter Druck herangeführt und über die Breite des Fugenbandes verteilt. DE-PS 30 11 225 is a similar procedure Ren known for the production of these joint tapes become. In this process, between two horizontal slabs across the resulting joints tied reinforcement bars in the form of flat, platfor miger elements supplied. Above and below this plate is the one through an inclined feed material to be extruded under pressure and distributed over the width of the joint tape.
Am Ende der Führungsplatten treffen sich die Teil ströme und umschließen die dort taktweise freigege benen Armierungsstäbe.The parts meet at the end of the guide plates currents and enclose the intermittent releases there reinforcement bars.
Die Armierungsstäbe, die vollständig von dem Kunst stoff umschlossen sind, werden so - zusammen mit dem Kunststoff - durch die profilierte Düse des Extruders gepreßt.The reinforcing bars, made entirely of art are enclosed in this way - together with the plastic - through the profiled nozzle of the Extruders pressed.
Insbesondere durch den letztgenannten Vorgang entstehen eine Reihe erheblicher Nachteile.In particular through the latter process there are a number of significant disadvantages.
Dadurch, daß der Armierungsstab die Düse mit durchquert, wird die Kunststoffschicht, die den Stab einschließt, im Querschnitt verringert. Beim nachfolgenden Abkühlvorgang, bei dem die Kunst stoffprofile etwa um 10% schrumpfen, folgt dieser eingefügte Stab diesem Schrumpfungsvorgang nicht. Das Fugenprofil wird wellig und die Gefahr, daß die Armierungsstäbe mit ihren scharfkantigen Enden die extrem dünne Kunststoffschicht durchstoßen, ist erheblich.The fact that the reinforcing rod with the nozzle traverses, the plastic layer that the Includes bar, reduced in cross section. At the subsequent cooling process, in which the art shrink fabric profiles by about 10%, this follows inserted rod does not shrink this process. The joint profile becomes wavy and there is a risk that the Reinforcing bars with their sharp-edged ends pierce extremely thin plastic layer considerably.
Die so gefertigten Teile sind zwar auf Baustellen leichter und mit weniger Aufwand handhabbar, weil hier der Einsatz von Federstahl möglich ist. Ein Verbiegen der Armierungsstäbe kann daher nahezu ausgeschlossen werden.The parts manufactured in this way are on construction sites easier and easier to handle because here the use of spring steel is possible. A Bending the reinforcing bars can therefore almost be excluded.
Das Durchstoßen der Außenwände an den Enden der Armierungsstäbe kann aber auch hier nicht mit Sicherheit vermieden werden.Puncturing the outer walls at the ends of the Reinforcing bars cannot be used here either Security can be avoided.
Man versuchte dem letztgenannten Mangel dadurch zu begegnen, daß man den Querschnitt der Düse des Extruders vergrößerte. Das gelang zwar, aber man vergrößerte damit auch unnötigerweise den Quer schnitt des Fugenbandes in den Bereichen, in denen sich keine Armierungsstäbe befanden. Die Fugenbän der werden teuer und schwer. This attempted to address the latter shortcoming encounter that the cross section of the nozzle of the Extruder enlarged. That did work, but one it also unnecessarily enlarged the cross cut the joint tape in the areas where there were no reinforcing bars. The joint tapes it will be expensive and heavy.
Der Erfindung liegt die Aufgabe zugrunde ein Ver fahren für die Herstellung von Fugenbändern mit quer eingefügten Armierungselementen vorzuschlagen, das gewährleistet, daß die Armierungselemente in beliebiger Form eingefügt werden können und eine Zerstörung des Kunststoffes o. dgl. im Bereich der Enden dieser Stäbe praktisch ausgeschlossen werden kann.

Die Form der Armierungselemente ist nicht mehr an die des Stabes gebunden, sondern kann jede beliebi ge Form einnehmen, die den gestellten Anforderun gen genügt. Auch Stäbe mit beliebigem Profil und scharfen Kanten sind einsetzbar.The shape of the reinforcement elements is no longer on that of the staff, but can be any take the form that meets the requirements is enough. Also bars with any profile and sharp edges can be used.
Die Verbindung der beiden Teilprofile kann je nach den vorhandenen Möglichkeiten nach einem der An sprüche 2 bis 5 erfolgen. Die Vorbereitung des Verbindungsvorganges richtet sich dann nach dem jeweiligen Verbindungsverfahren.The connection of the two sub-profiles can depend on the existing possibilities according to one of the An sayings 2 to 5. The preparation of the The connection process then depends on the respective connection method.
Bei der Verwendung von einzelnen, stabförmigen Armierungselementen ist es sinnvoll, die Zuführung derselben nach Anspruch 6 zu realisieren. When using single, rod-shaped Reinforcing elements, it makes sense to feed to implement the same according to claim 6.
Das Zusammenpressen der Teilprofile nach Anspruch 7 ist für die hier notwendige Massenproduktion mit hoher Zuverlässigkeit und geringem Energieaufwand möglich.The pressing of the partial profiles according to claim 7 is involved in the mass production necessary here high reliability and low energy consumption possible.
Das Verfahren nach Anspruch 8 ist dann zweckmäßig, wenn für das Kühlen Wasser unter hohem Druck zur Verfügung steht.The method according to claim 8 is then expedient if for cooling water under high pressure Available.
Die Ansprüche 9 bis 12 beinhalten vorteilhaft gestaltete Fugenbänder, die durch das erfindungsge mäße Verfahren herstellbar sind.Claims 9 to 12 contain advantageously designed joint tapes by the fictional appropriate processes can be produced.
Insbesondere, die in den Ansprüchen 11 und 12 defi nierten Fugenbänder, sind mit geringem Vorrich tungsaufwand herstellbar.In particular, the defi in claims 11 and 12 jointed joint tapes, are with little Vorrich manufacturing effort.
Sie gewährleisten die Grundfunktion der Armie rungselemente, vermeiden scharfe Kanten im Inneren des Fugenbandes vollständig und reduzieren den Materialeinsatz für die Armierungselemente in erheblicher Weise.They ensure the basic function of the armie elements, avoid sharp edges inside of the joint tape completely and reduce the Material use for the reinforcement elements in considerably.
Das Fugenband bleibt flexibel und ist auch auf Wickeln speicherfähig und transportierbar.The joint tape remains flexible and is also open Windable storage and transportable.
Durch das Verfahren ist es möglich, den Querschnitt des Profiles des Fugenbandes auf ein Minimum zu reduzieren und erhebliche Mengen an Material einzu sparen.Through the process it is possible to get the cross section the profile of the joint tape to a minimum reduce and insert significant amounts of material save up.
Die Erfindung soll nachstehend an Ausführungsbei spielen näher erläutert werden. In den dazugehöri gen Zeichnungen zeigen:The invention is intended to be carried out below play will be explained in more detail. In the associated show drawings:

Fig. 6 einen schematischen Querschnitt durch die Vorrichtung zur Herstellung eines Fugenbandes aus thermoplastischem Kunststoff. Fig. 6 shows a schematic cross section through the device for producing a joint tape made of thermoplastic material.
Die genormten Fugenbänder der definierten Art haben den prinzipiellen Aufbau, wie er in Fig. 1 darge stellt ist.The standardized joint tapes of the defined type have the basic structure as it is shown in Fig. 1 Darge.
Diese Fugenbänder 1 dienen dazu, vorzugsweise horizontale Stoßkanten von Betonteilen gegen das Eindringen von Wasser abzudichten.These joint tapes 1 are used to preferably seal horizontal abutting edges of concrete parts against the ingress of water.
Sie sind in senkrechter Lage mit ihrem unteren Abschnitt in eine erste, untere Wand etwa bis zu ihrem Mittelteil eingegossen.They are in a vertical position with their lower one Section into a first, lower wall approximately up to poured into their middle part.
Zur Vermeidung des Eindringens von Wasser entlang der Oberfläche des Fugenbandes 1 sind eine oder mehrere Dichtungslippen quer zur möglichen Durch laufrichtung des Wassers angeordnet.To avoid the penetration of water along the surface of the joint tape 1 , one or more sealing lips are arranged transversely to the possible direction of flow of the water.
Im äußeren Bereich befinden sich mehrere kleine, rippenartige Vorsprünge, die sich längs des Fugen bandes erstrecken und nach der Art der Labyrinth dichtungen evtl. kriechendes Wasser zurückhalten.In the outer area there are several small, rib-like projections that run along the joint Bandes extend and according to the type of labyrinth Retain seals and possibly creeping water.
Der mittlere Abschnitt des Fugenbandes 1 nimmt ge ringfügige Bewegungen der Betonteile gegeneinander auf und dient der direkten Abschirmung des Wassers zum anderen Raum. The middle section of the joint tape 1 takes ge slight movements of the concrete parts against each other and serves the direct shielding of the water to the other room.
Der obere Teil des Fugenbandes ist in gleicher Weise gestaltet wie der untere Teil.The upper part of the joint tape is the same Designed like the lower part.
Mit dem Ziel, zu vermeiden, daß der mittlere Teil, beim Eingießen des Betons für die obere Wand, in nachteiliger Weise seitlich abgeknickt wird und das Fugenband seine Funktion nicht mehr erfüllen kann, ist mindestens der mittlere Abschnitt des Fugenbandes durch querliegende Armierungselemente 13, die im Abstand voneinander angeordnet sind, verstärkt.With the aim of avoiding that the middle part, when pouring the concrete for the upper wall, is bent sideways disadvantageously and the joint tape can no longer fulfill its function, at least the middle section of the joint tape is provided by transverse reinforcement elements 13 are spaced apart, reinforced.
Für das Einbringen dieser Armierungselemente 13, in den Fig. 1 und 2, ausgebildet als Armierungsstab 131, wird das Fugenband 1 aus zwei unabhängig voneinander hergestellten Teilprofilen 11, 12 zusam mengesetzt und nach dem Einbringen der Armierungs elemente 13 miteinander verbunden.For the introduction of these reinforcing elements 13, shown in Figs. 1 and 2, designed as a reinforcing bar 131, the joint strip 1 consists of two independently prepared partial profiles 11, 12 together quantity sets and elements according to the introduction of the reinforcement 13 is connected.
Zu diesem Zweck besitzen die Teilprofile 11, 12 parallel zur längeren Achse ihres Querschnittes eine ebene Fläche. Diese ebenen Flächen beider Teilprofile 11, 12 sind gegeneinander gerichtet. Sie nehmen zwischen sich die Armierungsstäbe 13 auf und werden nach entsprechender Vorbereitung durch einen an sich bekannten Verbindungsvorgang unter Druck miteinander verbunden.For this purpose, the partial profiles 11 , 12 have a flat surface parallel to the longer axis of their cross section. These flat surfaces of both partial profiles 11 , 12 are directed towards each other. They hold the reinforcing bars 13 between them and, after appropriate preparation, are connected to one another under pressure by a known connecting process.
Das Verfahren zur Herstellung des Fugenbandes 1 ist dadurch gekennzeichnet, daß aus einem, in plasti scher Form vorliegendem Kunststoff 2 mit Hilfe eines. Extruders durch zwei entsprechende Düsen 31, 32 zwei zueinander spiegelbildliche Teilprofile 11, 12 hergestellt werden.The process for producing the joint tape 1 is characterized in that from a plastic 2 present in plastic form with the help of a. Extruder through two corresponding nozzles 31 , 32 two mutually mirror-image partial profiles 11 , 12 are produced.
Sie werden nach dem Austritt aus ihrer Düse 31, 32 durch die Führungsrolle 4 im definierten Abstand voneinander geführt. After emerging from their nozzle 31 , 32, they are guided by the guide roller 4 at a defined distance from one another.
In diesem Bereich wird über ein Führungsrohr 5 aus einem seitlich angeordneten Magazin (nicht darge stellt) in einem vorgegebenen Takt je ein Armie rungsstab 131 eingeführt und durch Absenken des Ablegers 51 auf der ebenen Fläche des unteren Teilprofiles 12 abgelegt.In this area, a reinforcement rod 131 is inserted via a guide tube 5 from a laterally arranged magazine (not shown) in a predetermined cycle and is deposited by lowering the branch 51 on the flat surface of the lower partial profile 12 .
Eine Heizvorrichtung, die insbesondere aus einem Wärme abstrahlenden Heizstab 6 besteht, werden die beiden einander gegenüberliegenden Flächen der Teilprofile 11, 12, die nach dem Extrudieren nur geringfügig abgekühlt waren, wieder erwärmt, so daß die Temperatur an den ebenen Flächen wieder bis nahe an den Schmelzpunkt erhöht wird.A heating device, which consists in particular of a heat radiating heating element 6 , the two opposite surfaces of the partial profiles 11 , 12 , which were only slightly cooled after extrusion, are heated again, so that the temperature on the flat surfaces again close to the Melting point is increased.
Zwischen den Druckwalzen (7), die aus der Stützwal ze 71 und den Preßwalzen 72 bzw. 73 bestehen, werden die beiden Teilprofile 11, 12 mit ihren zusätzlich erwärmten Flächen aneinander gepreßt und dabei miteinander verschweißt.Between the pressure rollers ( 7 ), which consist of the support roller ze 71 and the press rollers 72 and 73 , the two partial profiles 11 , 12 are pressed together with their additionally heated surfaces and thereby welded together.
Eine anschließend angeordnete Kühlvorrichtung 8 senkt die Temperatur des fertigen Fugenbandes 1.A subsequently arranged cooling device 8 lowers the temperature of the finished joint tape 1 .
Das Fugenband 1 schrumpft nach dem Schweißvorgang nur noch geringfügig und nimmt dabei seine endgül tige Form an.The joint tape 1 shrinks only slightly after the welding process and takes on its final shape.
Von besonderem Vorteil ist bei diesem geschilderten Verfahren, daß die beiden Teilprofile 11, 12 vor dem Einlegen bzw. Einbinden der Armierungselemente 13 bereits um 70 bis 80% ihres Schrumpfungsvorganges vollendet haben.It is of particular advantage in this described method that the two partial profiles 11 , 12 have already completed their shrinking process by 70 to 80% before inserting or integrating the reinforcing elements 13 .
Das Aufwärmen der inneren Oberflächen vor dem Schweißvorgang führt nicht noch einmal zu einer seitlichen Ausdehnung der Teilprofile 11, 12. The warming up of the inner surfaces before the welding process does not again lead to a lateral expansion of the partial profiles 11 , 12 .
Nachdem die Armierungselemente 13 zwischen den Teilprofilen 11, 12 eingeschlossen sind, werden diese unter relativ hohem elastischen Druck so zusammengepreßt, daß die Armierungselemente 13 vollständig zwischen den zusammengeschweißten Flächen eingeschlossen werden.After the reinforcing elements 13 are enclosed between the partial profiles 11 , 12 , these are pressed together under relatively high elastic pressure in such a way that the reinforcing elements 13 are completely enclosed between the welded surfaces.
Es ist von Vorteil, wenn in dem Querschnittsbereich des Fugenbandes 1, in dem die Armierungselemente 13 eingefügt sind, Druckwalzen 72 mit elastischer Oberfläche eingesetzt werden und in den Randzonen Druckwalzen 73 mit starrem Randprofil angeordnet sind.It is advantageous if pressure rollers 72 with an elastic surface are used in the cross-sectional area of the joint tape 1 , in which the reinforcing elements 13 are inserted, and pressure rollers 73 with a rigid edge profile are arranged in the edge zones.
Beide Druckwalzen 72, 73 dann man unabhängig vonei nander lagern und gegen die Teilprofile 11, 12 pressen, die ihrerseits von einer profilierten Stützwalze 71 geführt werden.Both pressure rollers 72 , 73 are then stored independently of one another and pressed against the partial profiles 11 , 12 , which in turn are guided by a profiled support roller 71 .
Auf diese Weise gewährleistet man, daß vor allem die Randzonen des Fugenbandes 1 vollständig ge schlossen sind und das Eindringen von Wasser zwi schen die Teilprofile 11, 12 absolut ausgeschlossen bleibt.In this way, it is ensured that, in particular, the edge zones of the joint tape 1 are completely closed and the penetration of water between the partial profiles 11 , 12 is absolutely excluded.
Zur Vorbereitung des Verbindungsvorganges kann man auch andere Mittel und Verfahren anwenden.To prepare the connection process you can use other means and procedures.
So ist es möglich, daß anstelle des Schweißvorgan ges ein Klebevorgang zum Verbinden der beiden Teilprofile 11, 12 durchgeführt wird.So it is possible that a gluing process for connecting the two partial profiles 11 , 12 is carried out instead of the welding process.
Zur Vorbereitung dieses Vorganges sprüht man auf die beiden miteinander zu verbindenden Flächen entweder ein Lösungsmittel für den Werkstoff der Teilprofile 11, 12 oder aber einen Haftkleber, der mit den Oberflächen der Teilprofile 11, 12 chemisch reagiert und unter Druck zu einer festen, stoffli chen Verbindung führt. To prepare this process, either a solvent for the material of the partial profiles 11 , 12 or a pressure sensitive adhesive is sprayed onto the two surfaces to be connected to one another, which reacts chemically with the surfaces of the partial profiles 11 , 12 and under pressure to form a solid, material-like connection leads.
Stellt man diese Teilprofile 11, 12 aus Gummi her, so kann man durch das Aufbringen von Schwefelpulver oder von Schwefel freisetzenden Stoffen den Verbin dungsvorgang vorbereiten und durch Einbringen von Wärme und Druck die beiden Teilprofile durch Vulka nieren miteinander verbunden.If you make these sub-profiles 11 , 12 from rubber, you can prepare the connec tion process by applying sulfur powder or sulfur-releasing substances and by introducing heat and pressure the two sub-profiles are connected together by vulcanizing.
Zur Erzeugung des Verbindungsdruckes muß man nicht unbedingt mit Walzen 72, 73 arbeiten.It is not absolutely necessary to work with rollers 72, 73 to generate the connection pressure.
Es ist auch möglich, daß der Verbindungsdruck durch das Kühlwasser erzeugt wird, das unter hohem Druck durch eine Breitschlitzdüse (Kühlvorrichtung 8) quer auf die Teilprofile 11, 12 gepreßt wird.It is also possible that the connection pressure is generated by the cooling water, which is pressed under high pressure through a slot die (cooling device 8 ) transversely onto the partial profiles 11 , 12 .
Mit bestimmten Vorteilen ist es auch möglich, den Druck für das Verbinden der Teilprofile 11, 12 durch einen schwingenden Stößel zu erzeugen. Dieser Stößel, angetrieben mit einer Bewegung in zwei Richtungen, kann auch Transportfunktionen - ähnlich dem Transporteur an Nähmaschinen übernehmen.With certain advantages, it is also possible to generate the pressure for connecting the partial profiles 11 , 12 by means of an oscillating plunger. This pestle, driven with a movement in two directions, can also perform transport functions - similar to the feed dog on sewing machines.
Das Einbringen der Armierungselemente 13 ist bei diesem Verfahren nicht mehr an die technologischen Bedingungen beim Extrudieren des Gesamtprofiles gebunden.In this method, the introduction of the reinforcing elements 13 is no longer tied to the technological conditions when extruding the overall profile.
Für das Einführen der Armierungselemente 13 zwi schen die Teilprofile 11, 12 steht ein größerer Raum zur Verfügung.For the insertion of the reinforcing elements 13 between the partial profiles 11 , 12 , a larger space is available.
Man ist mit dem beschriebenen Verfahren nicht mehr daran gebunden, gleiche Bedingungen über die gesamte Arbeitsbreite für das Einbinden der Armie rungsstäbe in den noch flüssigen Kunststoffstrom zu gewährleisten. One is no longer familiar with the method described tied to equal conditions over the total working width for integrating the armie rods in the still liquid plastic stream guarantee.
Damit hat man die Möglichkeit, auch Armierungsele mente 13 zu verwenden, die sich in Querrichtung nur über den Bereich erstrecken, der für das senk rechte Einbinden des oberen Fugenbandabschnittes unbedingt notwendig ist.This gives you the opportunity to use Armierungsele elements 13 , which extend in the transverse direction only over the area that is absolutely necessary for the vertical inclusion of the upper joint tape section.
Auf diese Weise sind mit dem vorliegenden Verfahren erhebliche Materialeinsparungen einerseits für die Armierungselemente 13 und andererseits für die Fugenbänder insgesamt möglich.In this way, considerable material savings are possible with the present method on the one hand for the reinforcing elements 13 and on the other hand for the joint tapes as a whole.
Die Dicke der schmalen Bereiche der Fugenbänder 1 kann auf ein Minimum reduziert werden, weil ihr Querschnitt beim Einbinden der Armierungselemente 131 weder geschwächt, noch durch die Schrumpfspan nungen übermäßig belastet wird.The thickness of the narrow areas of the joint tapes 1 can be reduced to a minimum because their cross-section when weaving the reinforcing elements 131 is neither weakened nor excessively stressed by the shrinkage stresses.
Der relativ große Raum zur Einführung der Armie rungselemente 13 gestattet es, auch endlos mitein ander verbundene Armierungselemente 131/1311; 132, 133, einzusetzen, die in der Ebene der zu verbindenden ebenen Flächen seitlich ausgelenkt sind.The relatively large space for the introduction of the reinforcement elements 13 allows reinforcement elements 131/1311 ; 132 , 133 , to be used, which are laterally deflected in the plane of the flat surfaces to be connected.
So ist es z. B. möglich, zwei einander unmittelbar benachbarte Armierungsstäbe 131 mittig durch flexible Verbindungselemente 1311 miteinander zu koppeln. Eine so entstehende Kette kann endlos zwischen die Teilprofile 11, 12 eingefügt werden (Fig. 5).So it is z. B. possible to couple two directly adjacent reinforcing bars 131 in the middle by flexible connecting elements 1311 . A chain created in this way can be inserted endlessly between the partial profiles 11 , 12 ( FIG. 5).
Ebenso ist es möglich, die Armierungselemente 132, 133 durch zick-zack- (Fig. 3) oder meanderför mig (Fig. 4) gebogene, endlose Drähte 133, 132 zu bilden. It is also possible to form the reinforcing elements 132 , 133 by zigzag ( Fig. 3) or meandering ( Fig. 4) bent, endless wires 133 , 132 .
Auseinandergezogene Windungen oder Spiralen aus relativ dünnem Draht sind in gleicher Weise als Armierungselemente 13 verwendbar.Pulled-out turns or spirals made of relatively thin wire can be used in the same way as reinforcing elements 13 .
Beim Einsatz dieser endlosen Armierungselemente 131/1311, 132, 133 kann man mit einfachen bogenför migen Führungen komplizierte Magaziniervorrichtun gen vermeiden.When using these endless reinforcement elements 131/1311 , 132 , 133 one can avoid complicated magazinungsvorrichtun conditions with simple bogenför guides.
Bei einer weiteren Form des Verfahrens werden die einzelnen Teilprofile 11, 12 räumlich und/oder zeitlich voneinander getrennt extrudiert, und auf einem bzw. zwei Wickeln gespeichert.In a further form of the method, the individual partial profiles 11 , 12 are extruded separately from one another in terms of space and / or time, and stored on one or two coils.
Zum Zwecke des Verbindens der beiden Teilprofile 11, 12 werden diese von den Wickeln abgezogen. Die Armierungsprofile 13 werden eingefügt, die ebenen Flächen für die Verbindung vorbereitet und unter Druck im beschriebenen Sinne miteinander verbunden.For the purpose of connecting the two partial profiles 11 , 12 , these are pulled off the coils. The reinforcement profiles 13 are inserted, the flat surfaces prepared for the connection and connected to one another under pressure in the manner described.
