Description

Die Erfindung betrifft einen Verpreßschlauch zum Herstellen von wasserundurchlässigen oder nur gering wasserdurchlässigen, gasdichten und/oder kraftschlüssigen Bauwerksfugen mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a compression hose for the manufacture of water-impermeable or only slightly water-permeable, gas-tight and / or non-positive structural joints with the features of the generic term of claim 1.

Bei der Herstellung von Bauwerken werden auf Fundamente, Bodenplatten oder dergleichen Wandabschnitte aufgesetzt. An diesen Anschlußstellen besteht die Gefahr der Wasserdurchlässigkeit. Um eine Abdichtfunktion oder Wassersperre zu bilden, werden im Bereich von derartigen Bauwerksfugen Verpreßschläuche angebracht. Zumeist werden die Anschlußwände auf die Fundamente oder Bodenplatten anbetoniert. Die Verpreßschläuche haben dabei die Aufgaben, zum einen in sich stabil zu bleiben, damit für den Fall der Undichtigkeit ein Injektionsmaterial in Schlauchlängsrichtung unter einem gewissen Förderdruck hindurchgeführt werden kann. Zum anderen soll ermöglicht sein, daß das Injektionsmaterial durch in dem Schlauch vorgesehene Durchbrechungen nach außen tritt, um eine dichtende Wirkung zu entfalten. Die Austrittsrichtung ist quer zur Schlauchlängsrichtung gesehen, so daß ggf. beim Anbetonieren auftretende Hohlräume durch Eindringen des Injektionsmaterials abgedichtet werden können. In the manufacture of structures, foundations, floor slabs or the same wall sections placed. At these junctions there is Danger of water permeability. To a sealing function or water barrier too form, are in the area of such structural joints grouting hoses appropriate. Mostly the connecting walls are on the foundations or Concrete base plates. The compression hoses have the tasks to one to remain stable in itself, so in the event of a leak Injection material in the longitudinal direction of the hose under a certain delivery pressure can be passed through. On the other hand, it should be possible for that Injection material through openings provided in the hose outside occurs to develop a sealing effect. The exit direction is transverse seen to the longitudinal direction of the hose, so that possibly occurring when concreting Cavities can be sealed by penetrating the injection material.

Des weiteren besteht die Aufgabe darin, daß während dem Anbetonieren der Anschlußwände die Durchbrechungen des Verpreßschlauches nicht zugesetzt werden bzw. daß die Betonmilch oder anderes Material, welches beim Herstellen einer Anschlußbetonierung eingesetzt wird, nicht in den Verpreßschlauch eindringt und diesen zusetzt.Furthermore, the task is that during the concreting the Connection walls the openings of the compression hose not clogged or that the concrete milk or other material used in the manufacture a connection concrete is used, does not penetrate the grouting hose and add to it.

Es ist bspw. ein Verpreßschlauch bekannt geworden, der einen Innenschlauch aufweist, in welchem quer zum Längsförderkanal Bohrungen eingebracht sind. Diese Bohrungen sind tangential durchgeführt, so daß sich eine Verbindung zum Längsförderkanal u nd zwei Austrittsöffnungen aus dem Innenschlauch ergeben. Um den Innenschlauch herum ist eine dünne, aus weichem Kunststoff ausgebildete Hülle vorgesehen, welche eng an dem Innenschlauch anliegt und die Bohrungen umschließt. Durch die geschlossene Außenhülle soll verhindert werden, daß während dem Anschlußbetonieren die Betonmilch in den Längsförderkanal des Innenschlauch e indringen kann u nd d iesen zusetzt. Dieser V erpreßschlauch ermöglicht zwar eine hinreichende Längsförderung des Injektionsmaterials, jedoch ist erforderlich, daß das Injektionsmaterial die den Innenschlauch umgebende Außenhülle derart aufweitet, daß diese platzt, um in die durch das Anschlußbetonieren entstandenen Hohlräume zu gelangen. Sofern ein Platzen des Schlauches nicht erfolgen sollte, kann lediglich ein radiales Dehnen der Außenhülle gegeben sein, wodurch jedoch feine haarrißförmige Hohlräume durch das Injektionsmaterial nicht geschlossen werden können.For example, a compression hose has become known that has an inner hose has, in which holes are made transversely to the longitudinal conveying channel. These holes are carried out tangentially, so that there is a connection to Longitudinal conveyor channel and two outlet openings result from the inner hose. Around the inner tube is a thin, made of soft plastic Envelope provided, which is close to the inner tube and the holes encloses. The closed outer shell is intended to prevent during the concreting the concrete milk into the longitudinal conveyor channel of the The inner hose can penetrate and clog it. This compression hose enables sufficient longitudinal conveyance of the injection material, however it is necessary that the injection material surrounds the outer sleeve surrounding the inner tube expands in such a way that it bursts into concrete through the connection cavities. Unless the hose bursts should not take place, only a radial stretching of the outer shell can be given be, however, creating fine hairline-shaped cavities through the injection material cannot be closed.

US-A-5,290,045 offenbart einen ähnlichen Verpreßschlauch bei dem die Außenhulle Durchborungen aufweist und aus einem wasserdehnbaren Gummi besteht, um das Eindringen von Betonmilch zu verhindern.US-A-5,290,045 discloses a similar compression hose in which the Outer shell has perforations and made of a water-elastic rubber to prevent the ingress of concrete milk.

Alternativ zu diesem Verpreßschlauch ist ein ähnlicher Verpreßschlauch bekannt geworden, der versetzt zu den Bohrungen im Schlauchmantel in einer Außenhülle, deren Wandstärke wesentlich stärker als die des vorbeschriebenen Verpreßschlauches ist, schlitzförmige Durchbrechungen aufweist. Diese schlitzförmigen Durchbrechungen in der Außenhülle sind versetzt zu den Bohrungen des Schlauchmantels angeordnet. Dadurch bedarf es eines erhöhten Druckes, um die relativ stark ausgebildete Außenhülle gegenüber dem Schlauchmantel aufzuweiten, um ein anschließendes Austreten des Injektionsmaterials durch die Durchbrechungen zu bewirken. Darüber hinaus ist die Herstellung derartiger Verpreßschläuche durch ein Koextrusionsverfahren relativ kostenintensiv. As an alternative to this compression hose, a similar compression hose is known become, which is offset to the holes in the hose jacket in an outer shell, whose wall thickness is much stronger than that of the above Compression hose, has slot-shaped openings. These slit-shaped Openings in the outer shell are offset from the holes in the Hose jacket arranged. This requires an increased pressure to the widening the relatively strong outer shell compared to the hose jacket, for a subsequent escape of the injection material through the openings to effect. In addition, the manufacture of such Injection hoses using a coextrusion process are relatively expensive.

Des weiteren ist ein Verpreßschlauch der Firma Reuß unter der Bezeichnung Duxpa-Rund bekannt geworden, welcher zum Verpressen von Injektionsmaterial eingesetzt wird. Der Schlauchmantel ist aus einem über die gesamte Wandstärke verteilten porenartigen Material ausgebildet, so daß ein dünnflüssiges Injektionsharz unter Druck durch die Poren gleichförmig austreten kann.Furthermore, a compression hose from Reuss is known as Duxpa-Rund became known, which is used to inject injection material is used. The hose jacket is made of one over the entire wall thickness distributed pore-like material, so that a low-viscosity injection resin can emerge uniformly through the pores under pressure.

Dieser Verpreßschlauch weist zwar den Vorteil auf, daß nur ein Schlauchmaterial verwendet w ird und somit dessen Herstellung einfach und kostengünstig ist, jedoch ist durch die porenartige Beschaffenheit des Verpreßschlauches der Nachteil gegeben, daß die Betonmilch oder dergleichen die zum Außenmantel hin offenen Poren zusetzt und beim Verpressen des Injektionsmaterials einen Austritt des Injektionsmaterials verhindert. Des weiteren weist dieser Verpreßschlauch den Nachteil auf, daß die Eigensteifigkeit dieses Verpreßschlauches gering ist, wodurch während dem Verpressen zunächst eine komplette Aufweitung des Schlauches erfolgt bevor ein Austritt des Injektionsharzes durch die Poren erfolgt, sofern diese nicht verklebt sind. Durch Anliegen des Verpreßschlauches in den Hohlräumen wird des weiteren das Austreten des Injektionsharzes bzw. des Injektionsmaterials in die benachbarten Risse beeinträchtigt.This compression hose has the advantage that only one hose material is used and thus its manufacture is simple and inexpensive, however is the disadvantage due to the pore-like nature of the compression hose given that the concrete milk or the like that open to the outer jacket Clogged pores and when the injection material is injected, the injection material emerges prevented. Furthermore, this compression hose has the Disadvantage that the inherent rigidity of this compression hose is low, which during the pressing process, a complete expansion of the hose takes place before the injection resin emerges through the pores, if these are not glued. By pressing the compression hose in the cavities furthermore the leakage of the injection resin or the injection material impaired in the neighboring cracks.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Verpreßschlauch zu schaffen, der einfach und kostengünstig herzustellen ist, D urchbrechungen aufweist, die beim Verpreßvorgang relativ leicht öffnen und ein Austreten des Injektionsmaterials ermöglichen sowie während dem Anbetonieren einer Wand oder dergleichen zufriedenstellende Verschließeigenschaften aufweist und der eine glatte Außenhaut aufweist, um ein Anhaften von Flüssigkeit oder Material des Bauwerkes zu verhindern.The invention is therefore based on the object of a compression hose create that is easy and inexpensive to manufacture, has openings, which open relatively easily during the pressing process and leakage of the injection material allow as well as while concreting a wall or the like has satisfactory sealing properties and one smooth outer skin to prevent adherence of liquid or material Prevent building.

Diese Aufgabe wird durch einen Verpreßschlauch mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a compression hose with the features of the claim 1 solved.

Durch den von innen nach außen abnehmenden Grad der Verschäumung des Schlauchmaterials eines Schlauchmantels ist ermöglicht, mit einem einteiligen Verpreßschlauch eine gute Längsförderung des Injektionsmaterials, eine Verschließeigenschaft der Durchbrechungen gegen von außen eindringende Flüssigkeiten oder Materialien während der Verarbeitung als auch eine glatte Außenhaut zu erzielen. Due to the decreasing degree of foaming from the inside out Hose material of a hose jacket is made possible with a one-piece Injection hose a good longitudinal conveyance of the injection material, a sealing property breakthroughs against liquids penetrating from outside or materials during processing as well as a smooth outer skin to achieve.

Durch einen an einem Innenraum in Schlaucherstreckungsrichtung angrenzenden porenartigen Bereich ist ermöglicht, daß eine leichte Öffnung der Durchbrechungen zum Innenraum erfolgt, so daß ein quasi düsenförmiger Austritt des Injektionsmaterials aus dem Schlauchmaterial gegeben ist. Durch den an einen Außenraum angrenzenden ungeschäumten o der nahezu u ngeschäumten Bereich wird eine hohe Festigkeit des Verpreßschlauches erzielt, wodurch auch die Durchbrechungen gute Wiederverschließeigenschaften aufweisen. Gleichzeitig kann dadurch eine glatte Außenhaut erzielt werden, wodurch einerseits ein Ankleben oder Haften von Flüssigkeit wie Betonmilch oder anderweitigem Material verhindert wird. Diese Ausgestaltung weist des weiteren den Vorteil auf, daß das Injektionsmaterial unmittelbar nach dem Austreten aus der Durchbrechung sich gleichförmig und ungehindert zwischen dem Schlauch und einem angrenzenden Wandabschnitt ausbreitet.By an adjacent to an interior in the hose extension direction pore-like area allows easy opening of the openings to the interior, so that a quasi nozzle-shaped outlet of the injection material is given from the hose material. By going to an outside space adjoining unfoamed o the almost non-foamed area achieved a high strength of the compression hose, which also caused the openings have good resealability. At the same time this can a smooth outer skin can be achieved, which on the one hand sticks or Adherence of liquids such as concrete milk or other material prevented becomes. This configuration also has the advantage that the injection material immediately uniform after exiting the opening and unimpeded between the hose and an adjacent wall section spreads.

Gleichzeitig kann durch die von innen nach außen abnehmende Verschäumung des Schlauchmaterials erzielt werden, daß während dem Verpressen des Verpreßschlauches bzw. dem Fördern des Injektionsmaterials eine nur bedingte radiale Aufweitung des Verpreßschlauches gegeben ist. Darüber hinaus weist der erfindungsgemäße Verpreßschlauch den Vorteil auf, daß wahlweise die Geometrie des Innenraumes als auch die Geometrie des Schlauchmantels, im Querschnitt gesehen, unabhängig voneinander gewählt und variiert werden kann. Durch die Einteiligkeit kann in Abhängigkeit der Extrusionsdüsen eine Variantenvielfalt an Geometrien des Innenraumes in Schlaucherstreckungsrichtung und Außenumfangs oder Querschnitts des Schlauchmantels ausgewählt werden.At the same time, foaming can decrease from the inside to the outside of the hose material are achieved that during the pressing of the compression hose or conveying the injection material is only a conditional one radial expansion of the compression hose is given. In addition, the Compression hose according to the invention has the advantage that the geometry is optional of the interior as well as the geometry of the hose jacket, in cross section seen, can be chosen and varied independently. Through the One-piece design can vary depending on the extrusion nozzles Geometries of the interior in the hose extension direction and outer circumference or cross-section of the hose jacket can be selected.

Die erfindungsgemäßen Verpreßschläuche können des weiteren in verschiedentlichen extrodierfähigen Kunststoffmaterialien hergestellt werden, wodurch eine funktionsgerechte Anwendung an unterschiedlichen Einsatzfällen ermöglicht ist.The compression hoses according to the invention can also be used in various ways extrudable plastic materials are produced, thereby creating a Functional application is possible in different applications.

Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Verpreßschlauches sind in den weiteren Unteransprüchen angegeben.Further advantageous refinements of the compression hose according to the invention are specified in the further subclaims.

In Figur 1 ist eine perspektivische Darstellung eines Verpreßschlauches 11 dargestellt. Dieser weist einen kreisrunden Profilkörper 12 auf, durch welchen ein Innenraum 13 als Längsförderkanal zur Längsförderung von Injektionsmaterial ausgebildet ist. Der Profilkörper 12 weist Durchbrechungen 14 auf, welche von dem Innenraum 13 durch die Wandstärke des Profilkörpers 12 nach außen in einen den Profilkörper 12 umgebenden Außenraum 16 führen. Die Durchbrechungen 14 sind bspw. gleichmäßig über den Umfang verteilt angeordnet und verlaufen längs der Längsachse 15 des Verpreßschlauches 11 in vorzugsweise regelmäßigen Abständen, welche frei bestimmbar sind. Im Ausführungsbeispiel sind vier gleichmäßig über den Umfang verteilt angeordnete Reihen von Durchbrechungen 14 in dem Verpreßschlauch 11 vorgesehen. In Abhängigkeit der Länge der Durchbrechungen als auch in Abhängigkeit der Verwendung des Injektionsmaterials können die Durchbrechungen, welche vorzugsweise als schlitzförmige Einstiche ausgebildet sind, länger oder kürzer ausgebildet sein und der Abstand der aufeinanderfolgenden Schlitze ist daran angepaßt. Alternativ können die Durchbrechungen auch tangential oder in einer zwischen radialer und tangentialer Lage in den Längsförderkanal münden. Die Durchbrechungen können anstelle einer geradlinigen, schlitzförmigen Ausgestaltung auch einen wellenlinienförmigen, sichelförmigen, V-oder W-förmigen Verlauf oder dergleichen aufweisen. Des weiteren kann die Anzahl der Reihen variiert werden. Vorzugsweise entspricht der Abstand zwischen den Schlitzen annähernd der doppelten Schlitzlänge.In Figure 1, a perspective view of a compression hose 11 is shown. This has a circular profile body 12 through which an interior 13 designed as a longitudinal conveying channel for the longitudinal conveyance of injection material is. The profile body 12 has openings 14, which from the interior 13 through the wall thickness of the profile body 12 to the outside in one Guide profile body 12 surrounding outer space 16. The openings 14 are For example, arranged evenly distributed over the circumference and run along the Longitudinal axis 15 of the compression hose 11, preferably at regular intervals, which are freely definable. In the exemplary embodiment, four are even Rows of openings 14 in arranged around the circumference the compression hose 11 provided. Depending on the length of the openings as well as depending on the use of the injection material the perforations, which are preferably formed as slot-shaped punctures are longer or shorter and the distance between the successive Slots is adapted to it. Alternatively, the openings can also tangentially or in a between radial and tangential position in the longitudinal conveyor channel lead. The openings can instead of a straight, slit-shaped design also a wavy, crescent, V or W-shaped course or the like. Furthermore, the number of the rows can be varied. The distance between preferably corresponds the slots approximately twice the slot length.

In Figur 2 ist ein Querschnitt des Profilkörpers 12 dargestellt, anhand dessen die Ausbildung der Verschäumung des Schlauchmaterials näher erörtert wird. Unterstützend w ird h ierbei a uch auf die Figur 3 bezug genommen, welche graphisch beispielhaft die Varianten über den Verlauf des Verschäumungsgrades über die Wandstärke darstellt. An den Innenraum 13 des Verpreßschlauches 11 angrenzend ist ein Bereich 17 vorgesehen, der porenartig ausgebildet ist. Der Anteil der Poren wird durch den Zusatz an Bläh- oder Treibmittel bestimmt, das die Verschäumung bewirkt. Dem Bereich 17 sind vorzugsweise 50 bis 65 % des Treibmittelanteils zugesetzt. Der Grad bzw. der Anteil der Ausbildung der Poren wird des weiteren durch die Extrusionsgeschwindigkeit, die Abkühlung als auch den verwendeten Kunststoff bestimmt. Der porenartige Bereich 17 weist vorteilhafterweise den größten Anteil an Verschäumung unmittelbar an den Innenraum 13 angrenzend auf und der Grad der Verschäumung nimmt zum Außenraum 16 hin ab. Der porenartige Bereich 17 umfaßt wenigstens ein Drittel der Wandstärke des Profilkörpers 12, so daß eine nur geringfügige Aufweitung des Verpreßschlauches 11 während dem Fördern des Injektionsmaterials gegeben ist. Von dem Außenraum 16 nach innen gesehen weist der Profilkörper 12 einen Bereich 18 auf, der ungeschäumt oder nahezu ungeschäumt ausgebildet ist. Dieser Bereich 18 umfaßt wenigstens ein Viertel der Wandstärke. Dadurch wird die Eigensteifigkeit des Profilkörpers 12 erzielt, so daß während dem Anbetonieren der Anschlußwand der Profilkörper 12 seine Querschnittform aufrechterhält. In einem Übergangsbereich 19 zwischen den Bereichen 17 und 18 nimmt der Grad der Verschäumung vorzugsweise kontinuierlich ab. In diesem Bereich 19 kann ein Treibmittelanteil von 30 bis 50 % vorgesehen sein.In Figure 2, a cross section of the profile body 12 is shown, based on which the Formation of the foaming of the hose material is discussed in more detail. supportive Reference is also made here to FIG. 3, which is shown graphically the variants on the course of the degree of foaming via the Represents wall thickness. Adjacent to the interior 13 of the compression hose 11 an area 17 is provided which is pore-like. The share of Pores are determined by the addition of blowing or blowing agents that cause foaming causes. The area 17 is preferably 50 to 65% of the proportion of blowing agent added. The degree or proportion of the formation of the pores is the further by the extrusion speed, the cooling and the used Plastic determined. The pore-like region 17 advantageously has the largest proportion of foaming directly adjacent to the interior 13 and the degree of foaming decreases towards the outside space 16. The pore-like region 17 comprises at least one third of the wall thickness of the profile body 12, so that only a slight expansion of the compression hose 11th during the conveyance of the injection material. From the outside 16 viewed inwards, the profile body 12 has an area 18 which is not foamed or is almost unfoamed. This area 18 comprises at least a quarter of the wall thickness. This creates the inherent rigidity of the profile body 12 achieved so that during the concreting of the connecting wall of the profile body 12 maintains its cross-sectional shape. In a transition area 19 between areas 17 and 18 the degree of foaming preferably increases continuously. In this area 19, a blowing agent content of 30 to 50% should be provided.

Der Anteil der Verschäumung kann, wie in Figur 3 dargestellt ist, einer Hyperbelfunktion 20 entsprechend zumindest angenähert sein. Die Ausgestaltung der einzelnen Bereiche 17, 18 und 19 ist variabel. Die Einflußgrößen zur Einstellung der Verhältnisse der Bereiche 17, 18, 19 zueinander können sowohl die Größe des Schlauches als auch die Wandstärke des Profilkörpers 12 als auch die Art bzw. Geometrie des Profilkörpers 12 sowie das verwendete Schlauchmaterial sein. Bspw. können sowohl leicht dehnbare Materialien wie gummielastische Kunststoffmaterialien, z. B. Silikone, als auch weniger kompressible Materialien oder kaum dehnbare Materialien eingesetzt werden.The proportion of foaming can, as shown in Figure 3, a hyperbolic function 20 be at least approximated accordingly. The design of the individual Areas 17, 18 and 19 are variable. The influencing variables for setting the Ratios of the areas 17, 18, 19 to each other can both the size of the Hose and the wall thickness of the profile body 12 as well as the type or Geometry of the profile body 12 and the hose material used. For example. can easily stretch materials such as rubber-elastic plastic materials, z. B. silicones, as well as less compressible materials or hardly stretchable materials are used.

Der Grad der V erschäumung k ann a uch kontinuierlich g emäß d em V erlauf 20a über die Wandstärke gesehen abnehmen. Durch den Anteil der zugeführten Menge an Treib- oder Blähmittel als auch durch die Verarbeitungsgeschwindigkeit wird der Verlauf der Kurven 20, 20a, 20b, welche den Grad der Verschäumung verteilt über die Wandstärke darstellen, bestimmt. Unterschiedliche Temperatureinflüsse können ebenfalls einen von den in Figur 3 dargestellten Verläufen oder beliebig davon abweichenden Verläufen bewirken. Die alternativen Verläufe sind bevorzugt zwischen den Bezugsziffern 20 und 20b. Selbstverständlich können auch jegliche, weitere Verläufe entsprechend vorgesehen sein.The degree of foaming can also be continuous according to the course 20a decrease over the wall thickness. By the proportion of the quantity supplied of blowing agents or blowing agents as well as the processing speed the course of the curves 20, 20a, 20b, which distributes the degree of foaming represent about the wall thickness, determined. Different temperature influences can also be one of the courses shown in Figure 3 or any cause deviating courses. The alternative courses are preferred between reference numerals 20 and 20b. Of course, any further courses can be provided accordingly.

Die in Figur 2 dargestellten Bereiche 17, 18, 19 verlaufen konzentrisch zueinander, wodurch der Verpreßschlauch 11 unabhängig der Einbaulage gleiche Verhältnisse aufweist. In Abhängigkeit der Geometrie des Profilkörpers 12 kann vorgesehen sein, daß einzelne Sektionen der Wandstärke im Verlauf der Verschäumung vom Innenraum 13 zum Außenraum 16 unterschiedlich ausgebildet sind, um eine bevorzugte Ausdehnungsrichtung oder eine bevorzugte Querförderung von Injektionsmaterial zu erzielen. Die Einteilung der Sektionen kann durch die Wahl der Geometrie unterstützt werden. Dabei kann sowohl der Innenraum 13 als auch der Außenraum 16 in seiner Geometrie voneinander abweichen, d. h. daß bspw. ein eckiger Außenumfang und ein runder Innenlängsförderkanal oder umgekehrt miteinander kombiniert werden, wobei bestimmte Ausdehnungseffekte oder eine leichtere Öffnung der Durchbrechungen durch die Gestaltung von Sektion unterstützt werden können.The regions 17, 18, 19 shown in FIG. 2 run concentrically to one another, whereby the compression hose 11 the same conditions regardless of the installation position having. Depending on the geometry of the profile body 12 can be provided be that individual sections of wall thickness in the course of foaming are designed differently from the interior 13 to the exterior 16 a preferred direction of expansion or a preferred transverse conveyance of To achieve injection material. The division of the sections can be made by choice the geometry are supported. Both the interior 13 and the outer space 16 differ from one another in its geometry, d. H. that e.g. an angular outer circumference and a round inner longitudinal conveyor channel or vice versa can be combined with each other, whereby certain expansion effects or a Easier opening of the openings is supported by the design of the section can be.

In Figur 4 ist eine alternative Ausgestaltung eines Verpreßschlauches 11 gemäß Figur 1 dargestellt. Dieser Verpreßschlauch 11 weist einen sechseckigen Profilkörper 12 auf, welcher mit einem sternförmigen Innenraum 13 ausgebildet ist. Der sechseckige Profilkörper 12 und der sternförmige Innenraum 13 sind derart zueinander positioniert, daß die spitz zulaufenden Verjüngungen 22 zu den Kanten 23 des sechseckigen Außenumfangs hin ausgerichtet sind. Gleichzeitig sind Durchbrechungen 14 an den Kanten 23 des sechseckigen Profilkörpers 12 vorgesehen, welche bis in die spitz zulaufenden Verjüngungen 22 des sternförmigen Innenraumes sich erstrecken. Dadurch kann ein zusätzlicher düsenförmiger Effekt zur Querförderung des Injektionsmaterials gegeben sein. Der Bereich 17 erstreckt sich vorteilhafterweise mit einer betragsmäßig gleichbleibenden Breite um den sternförmigen Innenraum 13. Dadurch kann zusätzlich der Effekt erzielt werden, daß während dem Verarbeiten des Schlauches durch Anbetonieren die Durchbrechungen 14 aufgrund der äußeren Krafteinwirkung der Anschlußwand oder dergleichen geschlossen gehalten werden.An alternative embodiment of a compression hose 11 according to FIG Figure 1 shown. This compression hose 11 has a hexagonal profile body 12, which is formed with a star-shaped interior 13. The hexagonal profile body 12 and the star-shaped interior 13 are mutually such positions that the tapered taper 22 to the edge 23rd of the hexagonal outer circumference are aligned. At the same time there are breakthroughs 14 provided on the edges 23 of the hexagonal profile body 12, which up to the tapered taper 22 of the star-shaped interior extend. This can create an additional nozzle-like effect Cross delivery of the injection material may be given. The area 17 extends advantageously with a constant width in terms of amount star-shaped interior 13. In this way, the effect can additionally be achieved that the openings during the processing of the hose by concreting 14 due to the external force of the connecting wall or the like be kept closed.

Diese Ausgestaltung ermöglicht eine präzise Einbringung der Durchbrechungen 14 zu den spitz zulaufenden Verjüngungen 22, da das Schlitzwerkzeug an einer Fläche 27 am Außenumfang des Profilkörpers 12 an-greift. Der Verpreßschlauch 11 gemäß Figur 5 kann alternativ zum Verpreßschlauch gemäß Figur 4 einen Bereich 17 aufweisen, der an die Außenkontur des Verpreßschlauches 11 angepaßt ist. Ebenso kann alternativ ein kreisrunder Bereich 28 vorgesehen sein, der den sternförmigen Innenraum 13 vollständig umgibt.As an alternative to FIG. 4, a compression hose 11 is provided, in which the tapers 22 of the star-shaped interior 13 are provided such that these along a longitudinal central axis 26 of individual surfaces 27 of the hexagonal Profile body 12 run. This configuration enables a precise introduction the openings 14 to the tapered taper 22, since the Slotted tool engages a surface 27 on the outer circumference of the profile body 12. The compression hose 11 according to FIG. 5 can alternatively to Compression hose according to FIG. 4 have an area 17 which is connected to the outer contour the compression hose 11 is adapted. Alternatively, a circular one Area 28 may be provided which completely completes the star-shaped interior 13 surrounds.

Ebenso kann die Anzahl der Kanten des Außenprofiles und die Anzahl der Verjüngungen 22 voneinander abweichen. Die Ausgestaltung des Bereichs 17 ist ebenso wahlweise möglich und nicht auf die beschriebene und dargestellte Ausführungsformen gemäß Figur 4 und 5 beschränkt.The embodiments shown in Figures 4 and 5 are polygonal on each Customizable external cross section. Likewise, the number of edges of the outer profile and the number of taper 22 differ. The Design of the area 17 is also possible and not on the described and illustrated embodiments according to Figures 4 and 5 limited.

In Figur 6 ist eine weitere alternative Ausführungsform eines Verpreßschlauches 11 dargestellt. Bspw. weist der Verpreßschlauch 11 ein achteckiges Außenprofil auf. Der Innenraum 13 ist abweichend zu einem kreisrunden Innenraum gemäß Figur 1 und 2 und einem sternförmigen Innenraum 13 gemäß Figur 4 und 5 als blumenförmiger oder mehrfach-kleeblattförmiger Innenraum 13 ausgebildet. Die Zuordnung der Durchbrechungen 14 zu dem Innenraum 13 kann derart erfolgen, daß diese eine Verbindung zwischen zwei Blättern 31 schaffen oder daß jedem Blatt 31 eine Reihe von Durchbrechungen 14 zugeordnet ist. Ebenso kann anstelle von acht gleichmäßig über den Umfang verteilte Reihen von Durchbrechungen 14 eine höhere oder niedere gerade und ungerade Anzahl von Reihen von Durchbrechungen 14 vorgesehen sein. Auch kann der Bereich 17 betragsmäßig mit gleichem Abstand sich um den Innenraum 13 erstrecken oder mit einem annähernd gleichbleibenden Radius um die Mittelachse 15 den Innenraum 13 umgeben. Des weiteren kann auch eine sektionsweise unterschiedliche Ausgestaltung des Verschäumungsgrades sowohl über den Umfang und/oder auch über den Querschnitt verteilt vorgesehen sein.FIG. 6 shows a further alternative embodiment of a compression hose 11 shown. For example. the compression hose 11 has an octagonal outer profile on. The interior 13 is different from a circular interior according to Figures 1 and 2 and a star-shaped interior 13 according to Figures 4 and 5 as flower-shaped or multi-leaf clover-shaped interior 13 is formed. The The openings 14 can be assigned to the interior 13 in such a way that these create a connection between two sheets 31 or that each Sheet 31 is assigned a series of openings 14. Likewise, instead of of eight rows of openings evenly distributed over the circumference 14 a higher or lower even and odd number of rows of openings 14 may be provided. The area 17 can also amount extend the same distance around the interior 13 or with an approximately constant radius around the central axis 15 surround the interior 13. Furthermore, a different configuration in sections can also be used the degree of foaming both over the scope and / or over the Cross section can be provided distributed.

In Figur 7 ist eine alternative Ausführungsform eines Verpreßschlauches 11 dargestellt. Bei diesem Verpreßschlauch 11 ist Befestigungsabschnitt 36 vorgesehen, der einstückig an den Schlauchmantel 12 anschließt. Dieser Befestigungsabschnitt 36 wird gleichzeitig mit dem Schlauchmantel 12 extrudiert. Dieser kann sich durchgehend über die gesamte Länge des Schlauches erstrecken oder wie in Figur 7 dargestellt abschnittsweise vorgesehen sein. Die Ausgestaltung und Form der Ausnehmung 37 zwischen den Befestigungsabschnitten 36 ist beliebig. Vorteilhafterweise sind die Befestigungsabschnitte 36 und Ausnehmungen 37 abwechselnd zueinander in gleichen Maßen ausgebildet, so daß diese durch ein rotierende Werkzeug hergestellt werden können. Diese Befestigungsabschnitte 36 weisen den Vorteil auf, daß Befestigungsbolzen in einfacher Weise auf dem Untergrund angebracht werden können, ohne daß, wie bisher im Stand der Technik bekannt, B efestigungsklammern z unächst s eparat a uf d em Schlauch aufgesetzt werden, um diese anschließend mit einem Befestigungsmittel auf der Unterlage zu fixieren. In Figur 7 ist der Befestigungsabschnitt symmetrisch zu dem Schlauchmantel vorgesehen. Es kann ebenso vorgesehen sein, daß bspw. eine untere Auflagefläche, deren Seitenkante 38 im Schnitt dargestellt ist, tangential in den Außenumfang des Schlauches mündet, so daß eine ebene Auflagefläche gegeben ist.
