Abstract

An injection hose intended for sealing expansion joint in concrete structures. The hose is in the form a continuous hollow extrusion (12), made of elastic, flexible material, with a continuous longitudinal bore (10) and at least one longitudinal groove (16). The groove (16) is connected to the bore (10) by means of apertures (22) in the wall of the extrusion and is fitted with a sealing strip (24), made of compressible, elastic material, which extends over the apertures (22). Production of the hose is made particularly simple and inexpensive by virtue of the fact that the width of the groove openings (26) is less than the diameter of the sealing strip (24) and that the means of holding the sealing strip (24) in place are formed by making undercuts in the side (30) of the groove (16).

Description

Die Erfindung betrifft einen Injektionsschlauch mit einem Profilstrang aus biegsamem, elastisch nachgiebigem Material, der einen durchgehenden Längskanal und mindestens eine durchgehende, über bodenseitige Durchbrüche mit dem Längskanal kommunizierende, durch seitliche Nutenflanken begrenzte und an einer Nutöffnung im wesentlichen radial offene Längsnut aufweist, und mit einem in der Längsnut angeordneten, mit Haltemitteln in dieser festgehaltenen, die Durchbrüche übergreifenden Dichtungsschnur aus gummielastisch nachgiebigen, vorzugsweise kompressiblem Material. Die Erfindung betrifft weiter ein Verfahren zur Herstellung eines solchen Injektionsschlauchs.The invention relates to an injection hose with a Profile strand made of flexible, resilient Material that has a continuous longitudinal channel and at least a continuous, through openings on the bottom communicating with the longitudinal channel, through lateral groove flanks limited and essentially at a slot opening has radially open longitudinal groove, and with a arranged in the longitudinal groove, with holding means in this held across the breakthroughs Sealing cord made of elastic, preferably compressible material. The invention further relates to a method for producing a such injection hose.

Injektionsschläuche dieser Art werden vorwiegend zum dauerhaften Abdichten von Arbeits- und Bewegungsfugen an Bauwerken, insbesondere an Betonbauwerken eingesetzt. Zu diesem Zweck wird der beim Betoniervorgang in die Fuge eingesetzte Injektionsschlauch über den Längskanal mit einem aushärtbaren Dichtstoff in flüssiger oder pastöser Form so unter Druck beaufschlagt, daß der Dichtstoff durch die Durchbrüche hindurch unter Abheben der Dichtschnur in die abzudichtende Fuge injiziert wird. Es ist ein Injektionsschlauch dieser Art bekannt (EP 0 522 327 A), bei welchem die Haltemittel für lose in die Längsnuten eingelegte Dichtungsschnüre durch einen über den Profilstrang gezogenen Strumpf aus einem dünnen, flüssigkeitsdurchlässigen oder sich unter der Einwirkung der Injektionsflüssigkeit auflösenden Material gebildet sind. Das Überziehen des Haltestrumpfes über die lose eingelegten Dichtschnüre und die Festlegung des Haltestrumpfes an den Enden eines abgelängten Profilstrangs bereiten fertigungstechnisch erhebliche Schwierigkeiten, die zu einer Verteuerung des Produkts führen. Dieser Nachteil macht sich vor allem bei einem nicht runden Querschnitt des Profilstrangs bemerkbar. Auch die Handhabung des mit dem Haltestrumpf überzogenen Profilstrangs läßt in der Praxis zu wünschen übrig.Injection hoses of this type are mainly used permanent sealing of construction and movement joints used on structures, especially on concrete structures. For this purpose, the in the concreting process Groove inserted injection hose over the longitudinal channel with a curable sealant in liquid or pasty form so pressurized that the Sealant through the openings while lifting off the sealing cord is injected into the joint to be sealed becomes. An injection hose of this type is known (EP 0 522 327 A), in which the holding means for loose sealing cords inserted into the longitudinal grooves by a sock pulled over the profile strand from a thin, liquid permeable or under the Exposure to the material dissolving the injection liquid are formed. Putting on the stocking about the loosely inserted sealing cords and the fixing of the stocking at the ends of a cut Profile strands prepare considerable manufacturing technology Difficulties that lead to an increase in the price of the product to lead. This disadvantage arises especially with one not round cross-section of the profile strand noticeable. Also the handling of the one covered with the holding stocking Profile strands leave something to be desired in practice.

DE 94 02 078 U betrifft einen Abdeckstreifen mit einer angepaßten Ausbildung. Zum Austreten von Injektionsmasse sind Durchtrittslöcher 1 im dann (unter Druck) durchgebogenen Abdeckstreifen vorgesehen. Der Profilstrang weiss keine Durchbrüche, sondern einen Querkanal zum Abdeckstreifen hin auf. Der Stand der Technik aus EP 0 692 584 A ist dem aus DE 94 02 078 U in etwa gleich wertig (Einlage 7, Trennschlitz 13).DE 94 02 078 U relates to a cover strip with a adapted training. For leakage of injection compound through holes 1 are then bent (under pressure) Cover strips provided. The profile strand has no openings, but a cross channel to the cover strip. The prior art from EP 0 692 584 A is that from DE 94 02 078 U approximately equivalent (insert 7, separating slot 13).

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, einen Injektionsschlauch der eingangs angegebenen Art sowie ein Verfahren zu dessen Herstellung zu entwickeln, womit die Herstellung ohne Funktionsnachteil vereinfacht und die Handhabung des Injektionsschlauchs verbessert werden kann.Proceeding from this, the invention is based on the object an injection hose of the type specified Art as well as a process for its production develop, with which the production without functional disadvantage simplified and the handling of the injection hose can be improved.

Zur Lösung dieser Aufgabe werden die in den Ansprüchen 1 und 12 angegebenen Merkmalskombinationen vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindungen ergeben sich aus den Unteransprüchen.To solve this problem are in the claims 1 and 12 specified combinations of features proposed. Advantageous refinements and developments of the inventions result from the subclaims.

Die erfindungsgemäße Lösung geht von dem Gedanken aus, daß bei einer geeigneten Formgestaltung des Profilstrangs auf die Verwendung eines Haltestrumpfes ohne Funktionsnachteil gänzlich verzichtet werden kann. Um dies zu erreichen, wird gemäß der Erfindung vorgeschlagen, daß die Öffnungsweite der Nutöffnung kleiner als der Durchmesser der Dichtungsschnur ist und daß die Haltemittel durch Hinterschneidungen in den Nutenflanken der Längsnut gebildet sind. Mit diesen Maßnahmen wird erreicht, daß die Dichtungsschnur aufgrund ihrer Eigenelastizität ausreichend fest in der Längsnut festgeklemmt werden kann, so daß sie beim Aufwickeln des Injektionsschlauchs auf eine Transportrolle, beim Ablängen von der Transportrolle und bei der Handhabung nicht verlorengeht. Die Dichtungsschnur dichtet den Längskanal gegen Flüssigkeitszutritt von außen ab, während sie bei einer Beaufschlagung des Längskanals mit flüssigem Dichtstoff unter Druck einen Austrittsspalt für den Dichtstoff nach außen freigibt, ohne aus der Längsnut verdrängt zu werden. Dadurch wird auch sichergestellt, daß nach Beendigung des Injektionsvorgangs sich der Durchtrittsspalt automatisch wieder schließt, so daß der Längskanal ohne Flüssigkeitseintritt von außen wieder leergesaugt werden kann.The solution according to the invention is based on the idea that with a suitable shape of the profile strand on the use of a holding stocking without Functional disadvantage can be dispensed with entirely. Around to achieve this is proposed according to the invention, that the opening width of the groove opening is smaller than is the diameter of the sealing cord and that the Holding means through undercuts in the groove flanks the longitudinal groove are formed. With these measures is achieved that the sealing cord due to their Self-elasticity clamped sufficiently firmly in the longitudinal groove can be so that when winding the Injection hose on a transport roller, when cutting to length from the transport roller and during handling not lost. The sealing cord seals the Longitudinal channel against liquid access from the outside while them when the longitudinal channel is loaded with liquid sealant under pressure an exit gap for the sealant to the outside without leaving the Longitudinal groove to be displaced. This also ensures that after completing the injection process the passage gap closes automatically, so that the longitudinal channel without liquid entry from the outside can be sucked empty again.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß der Durchmesser der Dichtungsschnur größer als die Tiefe der hinterschnittenen Längsnut ist, so daß ein Teil der in die Längsnut eingesetzten Dichtungsschnur radial über die Nutöffnung übersteht und dabei durch den Nutenrand eingeschnürt wird. Vorteilhafterweise sind hierzu die Nutenflanken im Bereich ihrer öffnungsseitigen Ränder im Profil hakenartig nach dem Nuteninneren gebogen. Grundsätzlich ist es auch möglich, daß die Nutenflanken zu diesem Zweck schwalbenschwanzartige Hinterschneidungen bilden. A preferred embodiment of the invention provides that the diameter of the sealing cord is larger than that Depth of the undercut longitudinal groove is, so that a Part of the sealing cord inserted in the longitudinal groove protrudes radially beyond the slot opening and through the groove edge is constricted. Advantageously are the groove flanks in the area of their opening side Edges in profile like hooks on the inside of the groove bent. Basically, it is also possible that the groove flanks are dovetail-like for this purpose Form undercuts.

Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß mindestens eine weitere, gegenüber dem Längskanal geschlossene, an ihren Seitenflanken hinterschnittene und außenseitige offene Längsnut vorgesehen ist, in der ein elastisch nachgiebiger, biegsamer Dichtungsstreifen aus unter Wasseraufnahme quellfähigem Material formschlüssig angeordnet ist. Mit einem solchen Dichtungsstreifen wird erreicht, daß bei Wassereintritt in eine Fuge der Dichtstreifen aus der betreffenden Längsnut nach außen quillt und die Fuge gegen Wasserdurchtritt abdichtet.Another preferred embodiment of the invention stipulates that at least one other, compared to the Longitudinal channel closed, undercut on its side flanks and provided on the outside open longitudinal groove is in which an elastically flexible, flexible sealing strip made of swellable material under water is arranged positively. With one Sealing strip is achieved that when water enters in a joint of the sealing strips from the concerned Longitudinal groove swells outwards and the joint prevents water penetration seals.

Der Profilstrang weist zweckmäßig ein mehreckiges, vorzugsweise dreieckiges Profil mit mittig angeordnetem Längskanal auf, an dessen Profilecken die mit den bodenseitigen Durchbrüchen versehenen und mit den Dichtungsschnüren bestückten Längsnuten angeordnet sind. Die zum Längskanal geschlossenen, mit den quellfähigen Dichtungsstreifen bestückten Profilnuten sind bei dieser Ausgestaltung zweckmäßig in den im wesentlichen ebenen Profilseiten des Profilstrangs angeordnet.The profile strand expediently has a polygonal, preferably triangular profile with a central one Longitudinal channel, on the profile corners of which with the bottom Breakthroughs and with the sealing cords equipped longitudinal grooves are arranged. The closed to the longitudinal channel, with the swellable Sealing strips equipped profile grooves are with this Design expedient in the main arranged flat profile sides of the profile strand.

Während der Profilstrang zweckmäßig aus einem Kautschuk, vorzugsweise aus EPDM-Kautschuk besteht, sind die Dichtungsschnüre zweckmäßig aus einem kompressiblem Moosgummi hergestellt. Die unter der Einwirkung von Wasser aufquellenden Dichtungsstreifen können aus einem mit Quellmittel, wie Urethanharz, Polyvinylalkohol oder Acrylharz versetzten Gummi bestehen. While the profile strand is expediently made of a rubber, The sealing cords are preferably made of EPDM rubber expediently from a compressible foam rubber manufactured. The under the influence of water swelling sealing strips can be made from a Swelling agents such as urethane resin, polyvinyl alcohol or Acrylic resin mixed rubber exist.

Bei der Herstellung der Injektionsschläuche wird nach dem erfindungsgemäßen Verfahren der aus einem Kautschuk bestehende Profilstrang über einen den Längskanal erzeugenden Dorn unter Einbringen der hinterschnittenen Längsnuten extrudiert und anschließend vulkanisiert und abgekühlt, wobei vor oder während des Vulkanisierungsvorgangs zumindest in einem Teil der Längsnuten des über den Dorn transportierten Profilstrangs im Abstand voneinander angeordnete Bodendurchbrüche unter Materialverdrängung eingedrückt werden. Anschließend werden dem vom Dorn abgezogenen und abgekühlten Profilstrang im Durchlauf von der Seite her von einer Vorratsrolle abgewickelte Dichtungsschnüre und/ oder Dichtungsstreifen zugeführt und in die zugehörigen Längsnuten eingedrückt. Der auf diese Weise konfektionierte biegsame Profilstrang wird schließlich partieweise auf Transportrollen aufgerollt und in der gewünschten Länge abgelängt.When manufacturing the injection hoses, the inventive method of a rubber existing profile strand over a longitudinal channel generating Mandrel by inserting the undercut Longitudinal grooves extruded and then vulcanized and cooled, before or during the vulcanization process at least in part of the longitudinal grooves of the Profile strands transported over the mandrel at a distance Bottom openings arranged from each other with material displacement be pushed in. Then be the extruded and cooled profile strand in a pass from the side from a supply roll unwound sealing cords and / or sealing strips fed and pressed into the associated longitudinal grooves. The flexible in this way Finally, the profile strand is transported in batches on transport rollers rolled up and cut to the desired length.

Der in der Zeichnung dargestellte Injektionsschlauch ist zum Abdichten von Arbeits- und Bewegungsfugen in Betonbauwerken bestimmt. Er weist einen mit einem zentralen Längskanal 10 versehenen, im Querschnitt im wesentlichen dreieckigen Profilstrang 12 auf, der im Bereich seiner Eckkanten 14 mit Längsnuten 16 und im Bereich seiner Seitenflächen 18 mit Längsnuten 20 versehen ist. Die Längsnuten 16 kommunizieren über im Abstand voneinander angeordnete bodenseitige Durchbrüche 22 mit dem Längskanal 10 und sind mit Dichtungsschnüren 24, aus einem gummielastischen, nachgiebigen und kompressiblen Material, wie Moosgummi, bestückt. Die Öffnungsweite der Nutöffnungen 26 ist kleiner als der Durchmesser der Dichtungsschnüre 24. Da auch die Nutentiefe kleiner als der Durchmesser der Dichtungsschnüre 24 ist, greifen die Dichtungsschnüre 24 durch die Nutöffnungen 26 nach außen durch und werden im Bereich des Öffnungsspalts durch die nach innen gebogenen Ränder 28 der Nutenflanken 30 in der in Fig. 1 gezeigten Weise eingeschnürt. Die Dichtungsschnüre 24 übergreifen innerhalb der Längsnuten 16 die Durchbrüche 22 und dichten dadurch den Längskanal gegen Flüssigkeitszutritt von außen her ab. Wird dagegen der Längskanal 10 unter Druck mit einem flüssigen Injektionsmittel beaufschlagt, so geben die nachgiebigen Dichtungsschnüre 24 Durchtrittsspalte für den Austritt des Injektionsmittels nach außen hin frei, ohne aus ihrer Längsnut 16 herausgedrängt zu werden. Als aushärtbare flüssige Injektionsmittel kommen beispielsweise wassermischbare, reaktiv härtende Kunstharze, Harze auf Vinylesterbasis, Polyurethanharze, Feinzement, Epoxidharze oder dergleichen in Betracht. The injection hose shown in the drawing is for sealing construction and movement joints in Concrete structures determined. He assigns one with a central one Longitudinal channel 10 provided, in cross section essentially triangular profile strand 12 on the area its corner edges 14 with longitudinal grooves 16 and in the area its side surfaces 18 provided with longitudinal grooves 20 is. The longitudinal grooves 16 communicate via at a distance openings on the bottom arranged from each other 22 with the longitudinal channel 10 and are with sealing cords 24, made of a rubber-elastic, compliant and compressible Equipped with material such as foam rubber. The opening width the groove openings 26 is smaller than that Diameter of the sealing cords 24. Since the groove depth smaller than the diameter of the sealing cords 24, the sealing cords 24 reach through the groove openings 26 to the outside and are in the area of Opening gap through the inwardly curved edges 28 of the groove flanks 30 in the manner shown in FIG. 1 constricted. The sealing cords 24 overlap within the longitudinal grooves 16 the openings 22 and seal thereby the longitudinal channel against liquid ingress from the outside. In contrast, the longitudinal channel 10 below Pressurized with a liquid injection agent, so give the flexible sealing cords 24th Passage gap for the injection agent to exit free to the outside without leaving its longitudinal groove 16 to be pushed out. As a curable liquid injection agent come, for example, water-miscible, reactive curing synthetic resins, resins based on vinyl esters, Polyurethane resins, fine cement, epoxy resins or the like into consideration.

Die in den Seitenflächen 18 des Profilstrangs 12 angeordneten Längsnuten 20 sind bodenseitig zum Längskanal 10 hin geschlossen. Sie weisen schwalbenschwanzförmig hinterschnittene Nutenflanken 32 auf und enthalten einen unter der Einwirkung von Wasser quellfähigen Dichtungsstreifen 34, der in der Nut formschlüssig verankert ist. Bei Wasserzutritt kann der Dichtungsstreifen bei geeigneter Materialwahl auf ein Mehrfaches seines Volumens aufquellen und einen zwischen dem Profilstrang 12 und einer benachbarten Betonfläche gebildeten Spalt gegen Wasserdurchtritt abdichten.The arranged in the side surfaces 18 of the profile strand 12 Longitudinal grooves 20 are on the bottom side of the longitudinal channel 10 closed. They have a dovetail shape undercut groove flanks 32 and contain one under the influence of water swellable sealing strips 34, which is positively anchored in the groove is. If there is water ingress, the sealing strip can with a suitable choice of material to a multiple of its Swell volume and one between the profile strand 12 and an adjacent concrete surface formed gap Seal against water penetration.

Aus dem Funktionsschema nach Fig. 2 ist ersichtlich, daß die für die Herstellung des Profilstrangs 12 bestimmte plastische Formmasse einem Extruder 40 über den Einlaß 42 zugeführt und mit Hilfe eines Antriebs 44 durch ein formgebendes Werkzeug 46 über einen Dorn 48 gepreßt wird. Der aus Metall bestehende Dorn 48 sorgt für die Ausbildung des Längskanals 10 im Profilstrang und dient außerdem den Noppenwalzen 52, mit denen die Durchbrüche 22 im Bereich der Längsnuten 16 in das noch plastische Strangmaterial eingebracht werden, als Widerlager. In der Vulkanisierungs- und Kühlstrecke 54, die je nach Extrusionsgeschwindigkeit mehrere zehn Meter lang sein kann, wird der Profilstrang ausgehärtet. In einer Konfektionierungsstufe 56 werden die von Vorratsrollen 58, 60 abgezogenen Dichtungsschnüre 24 und Dichtungsstreifen 34 dem vorbeilaufenden Profilstrang 12 im Durchlauf zugeführt und in die zugehörigen Längsnuten 16, 20 eingewalzt. Der auf diese Weise vorkonfektionierte Profilstrang 12 wird schließlich partieweise auf Transportrollen 62 aufgewickelt und in der Schneidstation 64 auf die gewünschte Länge abgelängt. Zusammenfassend ist folgendes festzustellen: Die Erfindung bezieht sich auf einen Injektionsschlauch, der für die Abdichtung von Arbeits- und Bewegungsfugen in Betonbauwerken bestimmt ist. Der Injektionsschlauch weist einen Profilstrang 12 aus biegsamem elastisch nachgiebigem Material auf, der einen durchgehenden Längskanal 10 und mindestens eine Längsnut 16 aufweist. Die Längsnut kommuniziert über bodenseitige Durchbrüche mit dem Längskanal und ist mit einer die Durchbrüche übergreifenden Dichtungsschnur 24 aus gummielastisch nachgiebigem, kompressiblem Material bestückt. Eine besonders einfache und kostengünstige Herstellung des Injektionsschlauchs wird dadurch ermöglicht, daß die Öffnungsweite der Nutöffnungen 26 kleiner als der Durchmesser der Dichtungsschnur 24 ist, und daß die Haltemittel zum Festhalten der Dichtungsschnur durch Hinterschneidungen in den Nutenflanken 30 der Längsnut gebildet sind.2 it can be seen that that intended for the manufacture of the profile strand 12 plastic molding compound an extruder 40 over the Inlet 42 fed and by means of a drive 44th by means of a shaping tool 46 via a mandrel 48 is pressed. The metal mandrel 48 ensures for the formation of the longitudinal channel 10 in the profile strand and also serves the knob rollers 52 with which the Breakthroughs 22 in the area of the longitudinal grooves 16 in the still plastic strand material are introduced as an abutment. In the vulcanization and cooling section 54, which depending on the extrusion speed several tens of meters can be long, the profile strand is cured. In a packaging stage 56, those of supply rolls 58, 60 removed sealing cords 24 and Sealing strip 34 the passing profile strand 12 fed in the pass and into the associated longitudinal grooves 16, 20 rolled. The prefabricated in this way Profile strand 12 finally becomes a lot wound on transport rollers 62 and in the Cutting station 64 cut to the desired length. In summary, the following can be stated: The invention refers to an injection hose designed for the sealing of construction and movement joints in concrete structures is determined. The injection hose points a profile strand 12 made of flexible, resilient Material on a continuous longitudinal channel 10 and has at least one longitudinal groove 16. The longitudinal groove communicates with the floor through openings Longitudinal channel and is with an overlapping breakthroughs Sealing cord 24 made of resilient, compressible material. A special one simple and inexpensive manufacture of the injection hose is made possible by the opening width of the slot openings 26 is smaller than the diameter of the Sealing cord 24, and that the holding means for Holding the sealing cord through undercuts are formed in the groove flanks 30 of the longitudinal groove.
