INJEKTIONSSCHLAUCH FÜR ARBEITSFUGEN AN BETONBAUWERKENINJECTION HOSE FOR JOINTS ON CONCRETE CONSTRUCTIONS
Beschreibung:Description:
Die Erfindung bezieht sich auf einen Injektionsschlauch für Arbeitsfugen an Betonbauwerken, mit einem im wesentlichen flüssigkeitsundurchlässigen, aus flexiblem Material wie Gummi oder Kunststoff bestehenden, einen Durchtrittskanal um¬ schließenden Grundkörper, welcher in seiner äußeren Mantel¬ fläche mit wenigstens einer sich über seine Länge erstrecken- den rillenartigen Vertiefung ausgestattet ist, in welche über deren Länge verteilt radiale Öffnungen für den Austritt von Injektionsflüssigkeit aus dem Durchtrittskanal münden und in welcher ein die Öffnungen überdeckender Streifen aus unter dem Innendruck der Injektionsflüssigkeit kompressiblem Mate- rial aufgenommen ist, und mit einer den Grundkörper und den Streifen schlauchartig umgebenden flüssigkeitsdurchlässigen Umhüllung.The invention relates to an injection hose for construction joints on concrete structures, with an essentially liquid-impermeable base body, which consists of flexible material such as rubber or plastic and encloses a through-channel and which in its outer jacket surface extends with at least one over its length. the groove-like recess is provided, into which radial openings for the injection liquid emerge from the passage channel, distributed over its length, and in which a strip covering the openings is accommodated from material which is compressible under the internal pressure of the injection liquid, and with one the base body and liquid-permeable covering surrounding the strip in the manner of a tube.
Aus der DE-GM 84 25 518 ist ein Injektionsschlauch für Ar- beitsfugen an Betonbauwerken mit einer im wesentlichen zylin¬ drischen flüssigkeitsdurchlässigen Wandung aus flexiblem Material, wie Gummi oder Kunststoff, bekannt, bei welcher die Wandung einen sich über ihre Länge erstreckenden Schlitz für den Austritt der Injektionsflüssigkeit aufweist, die Wandung im Bereich des Schlitzes eine sich ebenfalls über ihre Länge axial erstreckende Vertiefung für die Aufnahme eines den Schlitz überdeckenden Streifens aus unter dem Druck der In¬ jektionsflüssigkeit kompressiblem Material aufweist, und bei welchem die Wandung mit dem Streifen von einem Schlauch aus flüssigkeitsdurchlässigem Material umgeben ist. Ein solcher Injektionsschlauch hat herstellungstechnische Nachteile und wegen des im Vergleich zur Breite der Vertiefung relativ schmalen Austrittsschlitzes sind relativ hohe Verpressdrucke erforderlich, ohne daß man eine zuverlässig gleichmäßige Verteilung der Injektionsflüssigkeit über den Umfang des Injektionsschlauches erzielen kann.From DE-GM 84 25 518 an injection hose for construction joints on concrete structures with an essentially cylindrical liquid-permeable wall made of flexible material, such as rubber or plastic, is known, in which the wall has a slot extending over its length for the If the injection liquid emerges, the wall in the area of the slot has a recess, which also extends axially along its length, for receiving a strip covering the slot from material which is compressible under the pressure of the injection liquid, and in which the wall with the strip of one Hose is surrounded by liquid permeable material. Such an injection hose has manufacturing disadvantages and because of the relatively narrow outlet slit compared to the width of the recess, relatively high compression pressures are required without a reliably uniform one Distribution of the injection liquid over the circumference of the injection hose can achieve.
Diese Nachteile sind bei dem aus der DE-OS 35 12 470 bekann- ten Injektionsschlauch weitgehend dadurch vermieden, daß mehrere radiale Öffnungen im Grundkörper und die zugeordneten Vertiefungen und Streifen über den Umfang des Grundkörpers winkelsymmetrisch bezüglich der Längsmittelachse verteilt sind. Dies erfordert allerdings einen höheren Fertigungsauf- wand.These disadvantages are largely avoided in the injection hose known from DE-OS 35 12 470 in that several radial openings in the base body and the associated depressions and strips are distributed angularly symmetrically with respect to the longitudinal center axis over the circumference of the base body. However, this requires a higher manufacturing effort.
Aufgabe der Erfindung ist es, einen Injektionsschlauch der eingangs genannten Art vorzuschlagen, welcher bei einfacher Herstellung und verhältnismäßig niedrigen Verpressdrucken eine gleichmäßige Verteilung der Injektionsflüssigkeit über den Umfang des Injektionsschlauches zuläßt, so daß Arbeits¬ fugen beispielsweise auch mit Zement zuverlässig verpreßt werden können.The object of the invention is to propose an injection hose of the type mentioned at the outset which, with simple manufacture and relatively low compressive pressures, permits a uniform distribution of the injection liquid over the circumference of the injection hose, so that joints can also be reliably pressed, for example with cement.
Diese Aufgabe wird nach der Erfindung entweder dadurch ge¬ löst, daß eine einzige Vertiefung mit vorbestimmter Steigung wendeiförmig in der äußeren Mantelfläche des Grundkörpers umläuft oder dadurch, daß die einzige Vertiefung achsparallel verläuft, aber eine Öffnungsweite von mehr als 90° hat.According to the invention, this object is achieved either in that a single depression with a predetermined slope rotates helically in the outer circumferential surface of the base body, or in that the single depression runs axially parallel but has an opening width of more than 90 °.
Mit Hilfe beider Lösungswege wird die Fertigung des Injek¬ tionsschlauches vereinfacht, da nur eine einzige Vertiefung in der Mantelfläche des Grundkörpers vorgesehen werden muß, andererseits sind die Nachteile eines durchgehenden Schlitzes in dem Grundkörper vermieden, weil über die Länge des Grund¬ körpers verteilte radiale Durchtrit'tsöffnungen vorgesehen sind, und es wird entweder aufgrund der wendeiförmigen Ge¬ stalt der Vertiefung oder der verhältnismäßig großen Breite der Vertiefung überraschend eine außerordentlich gleichmäßige Verteilung der Injektionsflüssigkeit über den Umfang des Injektionsschlauches erzielt, so daß Arbeitsfugen mit höherer Sicherheit abgedichtet werden können.With the help of both solutions, the manufacture of the injection hose is simplified since only a single depression has to be provided in the lateral surface of the base body, on the other hand the disadvantages of a continuous slot in the base body are avoided because radial passage distributed over the length of the base body 'openings are provided, and there is surprisingly an extraordinarily uniform distribution of the injection liquid over the circumference of the depression either due to the helical shape of the depression or the relatively large width of the depression Injection hose achieved so that construction joints can be sealed with greater security.
Von besonderem Vorteil ist es, wenn die Umhüllung aus einem großmaschigen, die Mantelfläche des Grundkörpers und die Außenfläche des Streifens eng umschließenden dehnungsarmen Gewebe besteht, weil auf diese Weise der Injektionsschlauch beim Verpressen der Injektionsflüssigkeit keinerlei Umfangs¬ erweiterung erfährt, sondern lediglich eine innere Ventil- Wirkung aufgrund des Zusammendrückens des Streifenmaterials zum Tragen kommt. Denn der Streifen, welcher bei Vorliegen eines äußeren Druckes, beispielsweise des Betondruckes, die Öffnungen in der rillenförmigen Vertiefung schließt, und zwar um so besser je höher der Außendruck ist, wird unter dem Verpreßdruck von innen derart komprimiert, daß die Injek¬ tionsflüssigkeit leicht austreten kann. Aufgrund des deh¬ nungsarmen Gewebes kann hierbei der Injektionsschlauch seinen Querschnitt nicht verändern, was andernfalls zu einer unvoll¬ ständigen Abdichtung der Arbeitsfuge führen könnte.It is particularly advantageous if the sheathing consists of a large-mesh, low-stretch fabric that closely encloses the outer surface of the base body and the outer surface of the strip, because in this way the injection hose does not expand in size when the injection liquid is pressed, but only an inner valve Effect due to the compression of the strip material comes into play. This is because the strip, which closes the openings in the groove-shaped depression when there is external pressure, for example the concrete pressure, and the better the external pressure is, the inside compresses under the compression pressure in such a way that the injection liquid easily escapes can. Because of the low-stretch fabric, the injection hose cannot change its cross-section, which could otherwise lead to incomplete sealing of the construction joint.
Bei einer weiteren Ausgestaltung der Erfindung, bei welcher die verhältnismäßig breite Vertiefung achsparallel zum Durch¬ trittskanal verläuft, kann zur Materialersparnis vorgesehen sein, daß der Durchtrittskanal exzentrisch in dem zylindri- sehen Grundkörper angeordnet ist.In a further embodiment of the invention, in which the relatively wide recess runs axially parallel to the passage, it can be provided that the passage is arranged eccentrically in the cylindrical base body to save material.
Herstellungstechnisch ist es von Vorteil, wenn der Streifen unter Vorspannung in die Vertiefung eingeklebt ist.From a manufacturing point of view, it is advantageous if the strip is glued into the recess under pretension.
Im Rahmen der Erfindung können mit Vorteil in an sich bekann¬ ter Weise die seitlichen Begrenzungsflanken der Vertiefung und des Streifens von radial außen nach radial innen schräg aufeinander zulaufen. Hierbei ergibt sich ein besonders gün¬ stiger Öffnungsquerschnitt bei Anstehen des Verpreßdruckes von innen und eine besonders zuverlässige Abdichtung des Durchtrittskanals bei Anstehen eines Druckes von außen.Within the scope of the invention, the lateral boundary flanks of the depression and the strip can advantageously run obliquely towards one another from radially outside to radially inside in a manner known per se. This results in a particularly favorable opening cross-section when the pressing pressure is present from the inside and a particularly reliable seal of the passage when pressure is applied from the outside.
Der Öffnungsquerschnitt kann auch dadurch bei zuverlässiger Abdichtung günstig beeinflußt werden, daß die Breite der Basisfläche der Vertiefung nur geringfügig größer als der Durchmesser der Öffnungen ist.The opening cross section can also be favorably influenced with reliable sealing, that the width of the base surface of the recess is only slightly larger than the diameter of the openings.
In besonderer Ausgestaltung der Erfindung weisen die Vertie- fung und der Streifen einen im wesentlichen einander entspre¬ chenden trapezförmigen Querschnitt auf, mit leicht gekrümmter Basisfläche und dem Schlauchumfang entsprechend gekrümmter Außenfläche, so daß im Ruhezustand der Streifen die Vertie¬ fung praktisch vollständig ausfüllt.In a special embodiment of the invention, the recess and the strip have an essentially corresponding trapezoidal cross-section, with a slightly curved base surface and an outer surface correspondingly curved to the tube circumference, so that the recess practically completely fills the recess when the strip is at rest.
Der Abstand der radialen Öffnungen in der Vertiefung liegt in der Größenordnung von 1 bis 3 cm, ihr Durchmesser zwischen etwa 3 und 5 mm. Für den Querschnitt des Durchtrittskanals ist ein Durchmesser zwischen etwa 5 und 10 mm je nach Ver- pressmaterial zweckmäßig. Die Tiefe der Vertiefung liegt etwa in der Größenordnung zwischen 2 und 5 mm. Dies entspricht dann auch der Stärke der Streifen in nicht komprimiertem Zustand. Für den Grundkörper eignet sich als Material ins¬ besondere Polyvinylchlorid, für den Streifen Schaumgummi, Moosgummi oder Neopren. Die schlauchartige Umhüllung kann ein großmaschiges dehnungsarmes Klöppelgewebe sein.The distance between the radial openings in the recess is of the order of 1 to 3 cm, their diameter between about 3 and 5 mm. For the cross section of the passage channel, a diameter between about 5 and 10 mm is expedient, depending on the molding material. The depth of the depression is approximately in the range between 2 and 5 mm. This then also corresponds to the thickness of the strips in the uncompressed state. Polyvinyl chloride is particularly suitable as the material for the base body, and foam rubber, foam rubber or neoprene is suitable for the strip. The tube-like covering can be a large-mesh, low-stretch bobbin fabric.

Der Injektionsschlauch 1 besteht aus einem Grundkörper 2, der eine im wesentlichen hohlzylindrische Wandung hat und dadurch einen durchgehenden entwender zentralen (Fig. 1a, 1d und 3) oder exzentrischen achsparallelen zylindrischen Durchtritts¬ kanal 3 bildet. Durch den Durchtrittskanal 3 wird von einem Ende oder beiden Enden des Injektionsschlauches 1 bzw. ggf. auch bei dazwischen vorgesehenen Anschlüssen von diesen her eine später aushärtende Injektionsfiüssigkeit eingepreßt, um sie über die Länge einer abzudichtenden Arbeitsfuge eines Betonbauwerkes, in welche der Injektionsschlauch 1 eingelegt ist, zu verteilen. Die äußere Mantelfläche 4 des GrundkörpersThe injection hose 1 consists of a base body 2 which has an essentially hollow cylindrical wall and thereby forms a continuous steal central (Fig. 1a, 1d and 3) or eccentric axially parallel cylindrical passage channel 3. Through the passage channel 3, a later hardening injection fluid is pressed in from one end or both ends of the injection hose 1 or possibly also with connections provided therebetween, in order to extend it over the length of a construction joint to be sealed Distribute concrete structure in which the injection hose 1 is inserted. The outer lateral surface 4 of the base body
2 ist gemäß Fig. 1a und 1d mit einer sich über die Länge des Grundkörpers 2 erstreckenden rillenartigen wendeiförmig um- laufenden Vertiefung 5 ausgestattet. In die Vertiefung 5 münden über deren Länge verteilt radiale Öffnungen 6 für den Austritt von Injektionsflüssigkeit aus dem DurchtrittskanalAccording to FIGS. 1a and 1d, 2 is equipped with a groove-like, circumferential recess 5 extending over the length of the base body 2. Radial openings 6 for the discharge of injection liquid from the passage channel open into the recess 5 distributed over their length
3 in die abzudichtende Arbeitsfuge. In die Vertiefung 5 ist ein die Öffnungen 6 überdeckender langgestreckter Streifen 7 (Fig. 1b) eingelegt. Der Streifen 7 besteht aus einem unter dem Innendruck (Verpreßdruck) der Injektionsflüssigkeit kom- pressiblen Material, wie Neopren. Um den Streifen 7 in der Vertiefung 5 zu halten und eine Aufweitung des Querschnitts des Injektionsschlauchs 1 auch beim Verpressen zu vermeiden, ist der Grundkörper 2 mit dem eingelegten Streifen 7 eng von einer schlauchartigen flüssigkeitsdurchlässigen Umhüllung 8 umgeben. Aufgrund des Umstandes, daß die einzige Vertiefung 5 wendeiförmig umläuft, kann trotz der Verwendung nur eines einzigen Streifens 7 die Injektionsflüssigkeit beim Verpres- sen praktisch über den gesamten Umfang des Injektionsschlau¬ ches 1 verteilt gleichmäßig austreten. Die Umhüllung 8 be¬ steht vorzugsweise aus einem großmaschigen, die Mantelfläche3 in the construction joint to be sealed. An elongated strip 7 (FIG. 1b) covering the openings 6 is inserted into the recess 5. The strip 7 consists of a material such as neoprene that is compressible under the internal pressure (compression pressure) of the injection liquid. In order to keep the strip 7 in the recess 5 and to avoid widening the cross section of the injection hose 1 even when pressing, the base body 2 with the inserted strip 7 is closely surrounded by a hose-like liquid-permeable covering 8. Due to the fact that the single recess 5 rotates in a helical shape, the injection liquid can emerge evenly distributed over the entire circumference of the injection hose 1 despite the use of only a single strip 7. The covering 8 preferably consists of a large-meshed surface
4 des Grundkörpers 2 und die Außenfläche 9 des Streifens 7 eng umschließenden dehnungsarmen Gewebe, welche ein Auswei- chen des Streifens 7 auch bei erhöhtem Innendruck (Verpre߬ druck) verhindert. Die Großmaschigkeit des Gewebes gewähr¬ leistet einen ungestörten Austritt der Injektionsflüssigkeit beim Verpressen über den gesamten Umfang des Injektions¬ schlauches 1, während es umgekehrt ein Druck von außen, z.B. des Betons, auf den Streifen 7 zuläßt, wodurch dieser fest in die Vertiefung 5 eingepreßt und für eine Abdichtung des In¬ jektionsschlauches 1 von außen gesorgt wird, so daß keine nachteiligen Materialien in den Durchtrittskanal 3 gelangen und diesen verstopfen können. Durch die erfindungsgemäße Lösung ist daher eine jederzeit funktionsfähige innere Ven- tileinrichtung geschaffen, welche eine gleichmäßige Vertei¬ lung der Injektionsflüssigkeit beim Verpressen einer abzu¬ dichtenden Arbeitsfuge ohne Aufweitung des Injektions¬ schlauchquerschnittes gewährleistet.4 of the base body 2 and the outer surface 9 of the strip 7 tightly enclosing low-stretch fabric, which prevents the strip 7 from dodging even with increased internal pressure (compression pressure). The large mesh size of the tissue ensures an undisturbed discharge of the injection liquid during compression over the entire circumference of the injection hose 1, while conversely a pressure from the outside, for example of the concrete, allows the strip 7, as a result of which the latter is pressed firmly into the recess 5 and to ensure that the injection hose 1 is sealed from the outside, so that no disadvantageous materials get into the passage 3 and can block it. The solution according to the invention therefore enables an internal function that is functional at all times. created valve device, which ensures a uniform distribution of the injection liquid when pressing a work joint to be sealed without widening the injection hose cross-section.
Wenn, wie aus Fig 2 ersichtlich, der Durchtrittskanal 3 ex¬ zentrisch in dem zylindrischen Grundkörper 2 angeordnet ist, kann der Schlauchquerschnitt trotz einer verhältnismäßig großen Dicke des Streifens 7 und daher einer guten Öffnungs- und Schließfunktion einen verhältnismäßig geringen Quer¬ schnitt haben. Die Ausführungsform gemäß Fig. 2 bezieht sich dabei auf einen Injektionsschlauch 1 , bei welchem die Vertie¬ fung 5 und der Streifen 7 achsparallel zu dem Durchtritts¬ kanal 3 verlaufen und die Vertiefung 5 eine Öffnungsweite α von weniger oder mehr als 90° hat.If, as can be seen from FIG. 2, the passage channel 3 is arranged eccentrically in the cylindrical base body 2, the hose cross section can have a relatively small cross section despite a relatively large thickness of the strip 7 and therefore a good opening and closing function. The embodiment according to FIG. 2 relates to an injection hose 1 in which the recess 5 and the strip 7 run axially parallel to the passage channel 3 and the recess 5 has an opening width α of less or more than 90 °.
Bei der in Fig. 3 dargestellten Ausführungsform handelt es sich ebenfalls um einen Injektionsschlauch 1 , dessen Vertie¬ fung 5 und Streifen 7 achsparallel zu dem Durchtrittskanal 3 verlaufen, die Vertiefung 5 erstreckt sich aber über eine Öffnungsweite α von mehr als 90°, so daß auf diese Weise beim Verpressen eine hinreichend gleichmäßige Verteilung der In¬ jektionsflüssigkeit beim Verpressen über den Umfang des In¬ jektionsschlauches 1 erzielbar ist.The embodiment shown in FIG. 3 is also an injection hose 1, the recess 5 and strips 7 of which run axially parallel to the passage 3, but the recess 5 extends over an opening width α of more than 90 °, so that in this way, a sufficiently uniform distribution of the injection liquid can be achieved when pressing over the circumference of the injection hose 1 during the pressing.
Allen dargestellten besonderen Ausgestaltungen ist gemeinsam, daß die seitlichen Begrenzungsflanken 10 der Vertiefung 5 und des Streifens 7 von radial außen nach radial innen schräg aufeinander zu verlaufen. Die Vertiefung 5 und der Streifen 7 weisen dann vorzugsweise einen im wesentlichen einander entsprechenden trapezförmigen Querschnitt auf, mit leicht gekrümmter Basisfläche 11 des Streifens 7 bzw. der Vertiefung 5 und dem Schlauchumfang entsprechend gekrümmter Außenfläche 9 des Streifens 7. Allen Ausführungen ist auch gemeinsam, daß die breite der Basisfläche 11 der Vertiefung 5 nur geringfü- gig größer als der Durchmesser der radialen Öffnungen 6 ist, so daß die innere Ventileinrichtung des erfindungsgemäßen Injektionsschlauches 1 schon bei verhältnismäßig niedrigen Verpreßdrucken öffnet, andererseits aber bei Druckbeaufschla- gung des Streifens 7 von außen eine zuverlässige Abdichtung gewährleistet ist. Anstelle des trapezförmigen Querschnitts der Vertiefung kann diese selbstverständlich auch jede belie¬ bige andere Form aufweisen, solange sie zur Aufnahme eines entsprechenden komprimierbaren Streifens, einer Rundschnur oder dgl. geeignet ist. So kann sie halbrund, oval oder dgl. ausgeformt sein. It is common to all the special configurations shown that the lateral boundary flanks 10 of the depression 5 and the strip 7 run obliquely towards one another from radially outside to radially inside. The depression 5 and the strip 7 then preferably have an essentially corresponding trapezoidal cross section, with a slightly curved base surface 11 of the strip 7 or the recess 5 and the outer circumference 9 of the strip 7, which is curved corresponding to the tube circumference. All versions also have in common that the width of the base surface 11 of the recess 5 is only slightly gig is larger than the diameter of the radial openings 6, so that the inner valve device of the injection hose 1 according to the invention opens even at relatively low compression pressures, but on the other hand a reliable seal is ensured when the strip 7 is pressurized from the outside. Instead of the trapezoidal cross section of the depression, it can of course also have any other shape as long as it is suitable for receiving a corresponding compressible strip, a round cord or the like. So it can be semicircular, oval or the like. Shaped.
