The outside (8) of the insert can be set back relative to an imaginary plane (10) connecting the lateral edges (9) of the base face (11) of the basic element. The side flanks (6) of the indentation can project wedged shape relative to each other. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Dichtung für Arbeitsfugen in und an Betonbauwerken mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a seal for construction joints in and on concrete structures with the features of the preamble of claim 1.

Eine Dichtung dieser Art ist aus dem DE-GM 84 25 518 bekannt. Sie ist als Injektionsschlauch ausgebildet. Der aus Gummi oder Kunststoff gefertigte Schlauch besitzt eine flüssigkeitsdurchlässige Wandung. Diese Wandung weist einen sich über ihre Länge erstreckenden Schlitz für den Austritt einer Injektionsflüssigkeit auf. In der Wandung ist im Bereich des Schlitzes eine sich ebenfalls über ihre Länge erstreckende Vertiefung für die Aufnahme eines den Schlitz überdeckenden Streifens vorgesehen, der aus einem unter dem Druck der Injektionsflüssigkeit volumsveränderndem Material besteht. Die Wandung mit den Streifen ist von einem Schlauch aus flüssigkeitsdurchlässigem Material umschlossen. Dieser Injektionsschlauch besteht somit aus drei zusammengefügten Teilen, die ein langgestrecktes flexibles Gebilde darstellen. Der erwähnte Streifen aus kompressiblem Material ist aus Moosgummi gefertigt.A seal of this type is known from DE-GM 84 25 518. It is designed as an injection hose. The hose made of rubber or plastic has a liquid-permeable wall. This wall has a slot extending over its length for the discharge of an injection liquid. Provided in the wall in the area of the slot is a depression, likewise extending over its length, for receiving a strip covering the slot, which is made of a material that changes volume under the pressure of the injection liquid. The wall with the strips is enclosed by a tube made of liquid-permeable material. This injection hose thus consists of three joined parts that form an elongated, flexible structure. The aforementioned strip of compressible material is made of foam rubber.

Vergleichbare Konstruktionen zeigen und beschreiben folgende Druckschriften: DE-GM 91 11 114, DE-GM 83 00 766, DE-OS 33 20 875, DE-OS 34 00 654, DE-OS 35 12 470, DE-OS 41 23 067, DE-OS 41 24 628 und EU-PS 199 108. Soll beispielsweise auf einer Betondecke eine Betonmauer errichtet werden, so wird ein Schlauch der vorstehend erwähnten Art auf die Betonplatte gelegt und hier fixiert, und zwar innerhalb jenes Bereiches, der von der Schalung für die zu errichtende Mauer begrenzt ist. Die beiden Enden des Schlauches werden nach außen geführt. Ist der Beton für die Mauer in die Schalung eingebracht und ist er in der Folge ausgehärtet, so wird in den Schlauch eine Injektionsflüssigkeit eingepreßt, die die zwischen Platte und Mauer befindlichen Fugen dichtend füllt. Alle diese Dichtungen sind relativ aufwendig gebaut.Comparable constructions show and describe the following documents: DE-GM 91 11 114, DE-GM 83 00 766, DE-OS 33 20 875, DE-OS 34 00 654, DE-OS 35 12 470, DE-OS 41 23 067, DE-OS 41 24 628 and EU-PS 199 108. If, for example, a concrete wall is to be erected on a concrete ceiling, a hose of the type mentioned above is placed on the concrete slab and fixed here, specifically within that area of the formwork for the wall to be built is limited. The two ends of the hose are led outside. Once the concrete for the wall has been placed in the formwork and has subsequently hardened, an injection liquid is injected into the hose, which fills the joints between the plate and the wall in a sealing manner. All of these seals are relatively expensive.

Bekannt sind ferner Dichtungsmaterialien aus Kunststoffmassen (DE-OS 42 26 198 und DE-OS 42 26 385), die beim Kontakt mit Wasser aufquellen und die zur Fugenabdichtung oder auch zum Ausgleich von Dimensionsänderungen im Hoch-, Tief- und Ingenieurbau oder in anderen technischen Bereichen eingesetzt werden. Aus diesem Material werden Streifen mit beispielsweise rechteckigem Querschnitt gefertigt. Bei der Errichtung eines Mauerwerkes, wie vorstehend beschrieben, werden solche Streifen auf die Betonplatte aufgelegt und fixiert, und zwar innerhalb der Schalung, die für die zu errichtende Mauer dient. Wird ein solcher Dichtstreifen eventuell bei regennassem Wetter verlegt, so quillt er auf, bevor der Beton für die Mauer in die Schalung eingebracht werden kann. Erreicht er dabei sein maximales Volumen, so ist seine Dichtfähigkeit in der Folge in Frage gestellt. Diese Dichtung ist nach Fertigstellung der Mauer nicht mehr zugänglich.Also known are sealing materials made of plastic materials (DE-OS 42 26 198 and DE-OS 42 26 385), which swell on contact with water and which are used to seal joints or to compensate for dimensional changes in civil engineering, civil engineering or other technical applications Areas are used. Strips with, for example, a rectangular cross section are made from this material manufactured. When erecting masonry, as described above, such strips are placed and fixed on the concrete slab, within the formwork that serves for the wall to be erected. If such a sealing strip is installed in wet weather, it will swell before the concrete for the wall can be placed in the formwork. If it reaches its maximum volume, its sealing ability is subsequently called into question. This seal is no longer accessible after completion of the wall.

Von diesem Stand der Technik geht die Erfindung aus und sie zielt darauf ab, eine Dichtung der erwähnten Art vorzuschlagen, die die aufgezeigten Nachteile nicht besitzt, die also einfacher aufgebaut ist und die auch noch nach ihrer Verlegung und Einbindung in das Mauerwerk beeinflußbar ist und welche auch bei regennassem Wetter eingebaut werden kann, ohne daß sie dadurch in der Folge ihre Dichtfähigkeit verliert; vor allem aber soll die erfindungsgemäße Dichtung von vorne herein bereits bessere Dichteigenschaften aufweisen als die bislang bekannten vergleichbaren Konstruktionen. Zur Lösung dieser komplexen Aufgabe schlägt die Erfindung jene Maßnahmen vor, die Inhalt und Gegenstand des kennzeichnenden Teiles des Patentanspruches 1 sind.The invention is based on this prior art and it aims to propose a seal of the type mentioned which does not have the disadvantages shown, which is therefore of simpler construction and which can also be influenced after it has been installed and incorporated into the masonry, and which can be installed even in rainy weather, without losing its sealing ability as a result; but above all, the seal according to the invention should already have better sealing properties from the outset than the previously known comparable constructions. To solve this complex problem, the invention proposes those measures that are the content and subject of the characterizing part of claim 1.

Eine zweckmäßige Ausführungsform der Erfindung wird anhand der Zeichnung näher erläutert, ohne dadurch die Erfindung auf eben dieses Ausführungsbeispiel einzuschränken. Die Figur zeigt den Querschnitt der erfindungsgemäßen Dichtung.An expedient embodiment of the invention is explained in more detail with reference to the drawing, without thereby restricting the invention to this exemplary embodiment. The figure shows the cross section of the seal according to the invention.

Die Dichtung besitzt einen Grundkörper 1 aus elastischem Material, der hier beim gezeigten Ausführungsbeispiel die Gestalt eines gleichschenkligen Dreieckes aufweist. Das Verhältnis der Breite B der Basiskante 9 - 9 zur Höhe H des Querschnittes beträgt annähernd 1,5. Dieser Grundkörper 1 besitzt eine innere, längsverlaufende, bohrungsartige Ausnehmung 2. Diese hier im Querschnitt kreisrunde Ausnehmung 2 ist so groß und liegt in der Weise innerhalb des Querschnittes des Grundkörpers 1, daß die Wandung 3 dieser Ausnehmung 2 mit den beiden Außenflächen 4 des Grundkörpers 1 je eine längsverlaufende, dünnwandige Sollbruchstelle 14 begrenzt. Im Basisbereich besitzt dieser Grundkörper 1 eine längsverlaufende, nutartige Vertiefung 5, deren Seitenflanken 6 keilartig gegeneinander vorspringen. In dieser nutenartigen Vertiefung 5 liegt die Einlage 7 aus quellbarem Material, die zweckmäßigerweise in diese nutartige Vertiefung 5 eingegossen ist. Die Außenseite 8 der aus quellbarem Dichtungsmaterial bestehenden Einlage 7 ist gegenüber einer gedachten, die Randkanten 9 der Basisfläche 11 des Grundkörpers 1 verbindenden Ebene 10 etwas zurückversetzt, so daß diese Außenseite 8, wenn die Dichtung auf eine ebene Fläche aufgelegt wird, von dieser etwas distanziert ist.The seal has a base body 1 made of elastic material, which here has the shape of an isosceles triangle in the embodiment shown. The ratio of the width B of the base edge 9 - 9 to the height H of the cross section is approximately 1.5. This base body 1 has an inner, longitudinal, bore-like recess 2. This recess 2, which is circular in cross section here, is so large and lies within the cross section of the base body 1 in such a way that the wall 3 of this recess 2 with the two outer surfaces 4 of the base body 1 each a longitudinal, thin-walled predetermined breaking point 14 limited. In the base region, this base body 1 has a longitudinal, groove-like depression 5, the side flanks 6 of which protrude toward one another in a wedge-like manner. In this groove-like recess 5 lies the insert 7 made of swellable material, which is expediently cast into this groove-like recess 5. The outside 8 of the insert 7, which consists of swellable sealing material, is opposite an imaginary one, the edge edges 9 of the base surface 11 of the base body 1 connecting level 10 slightly set back, so that this outer side 8, when the seal is placed on a flat surface, is somewhat distanced from this.

Die Breite B der Basisfläche 11 des Grundkörpers 1 ist größer als die Breite b der Einlage 7 und die von den Randkanten 9 ausgehende Basisfläche 11 des Grundkörpers 1 schließt mit einer gedachten, diese Randkanten 1 verbindenden Ebene 10 zur Bildung von an die Seitenränder der Einlage 7 anschließende Dichtlippen 12 einen spitzen Winkel α ein. Dieser spitze Winkel α beträgt annähernd 15°.The width B of the base surface 11 of the base body 1 is greater than the width b of the insert 7 and the base surface 11 of the base body 1 starting from the edge edges 9 closes with an imaginary plane 10 connecting these edge edges 1 to form the side edges of the insert 7 subsequent sealing lips 12 an acute angle α. This acute angle α is approximately 15 °.

Zwischen der nutartigen Vertiefung 5 und der Ausnehmung 2 ist noch ein Trennschlitz 13 eingearbeitet. Besitzt die Dichtung nach dem gezeigten Ausführungsbeispiel einen dreieckförmigen Querschnitt, so liegt es im Rahmen der Erfindung, diesen Querschnitt auch rechteckig oder trapezförmig zu gestalten. Anstelle einer Ausnehmung 2 können innerhalb eines solchen Querschnittes auch mehrere solche parallel verlaufende Ausnehmungen vorgesehen werden. Die Umfangskontur dieser Ausnehmung 2 ist nicht an die Kreisform gebunden. Auch eine vieleckige Umfangskontur wäre denkbar, wobei dann dieser Querschnitt gegenüber dem Außenquerschnitt der Dichtung so gelegt ist, daß eventuell eine Ecke dieses Querschnittes der Ausnehmung 2 zur Bildung der Sollbruchstelle 14 dient.Between the groove-like recess 5 and the recess 2, a separating slot 13 is also incorporated. If the seal according to the exemplary embodiment shown has a triangular cross section, it is within the scope of the invention to also make this cross section rectangular or trapezoidal. Instead of a recess 2, a plurality of such parallel recesses can also be provided within such a cross section. The circumferential contour of this recess 2 is not tied to the circular shape. A polygonal circumferential contour would also be conceivable, in which case this cross section is placed relative to the outer cross section of the seal in such a way that a corner of this cross section of the recess 2 is used to form the predetermined breaking point 14.

Diese Dichtung wird auf einer Baustelle in der Weise verlegt, wie dies eingangs im Zusammenhang mit den vorbekannten Konstruktionen erörtert wurde. Die beiden Enden der Dichtung werden aus der Schalung herausgeführt. Diese Dichtung kann auch bei regennassem Wetter verwendet werden, weil, wie die Abbildung zeigt, durch die Dichtlippen 12 die Einlage 7 aus quellfähigem Material von der Auflagefläche, hier durch die gedachte Ebene 10 dargestellt, distanziert ist. Ist der Beton zur Errichtung der Mauer eingefüllt, so lastet sein Gewicht auf der Dichtung auf und drückt dabei die Dichtlippen 12 flach und damit die Einlage 7 an die Auflagefläche, wobei nun die Einlage 7 aufzuquellen beginnt, wenn sie durch diesen Kontakt mit der Auflagefläche benetzt wird. Sollte in der Folge festgestellt werden, daß die bestehende Bauwerksfuge durch diese Dichtung nicht ausreichend abgedichtet werden konnte, beispielsweise weil der eingebrachte Beton einen allzu großen Schwund aufweist, so wird mittels bekannter Vorrichtungen in diese Dichtung, und zwar in die Ausnehmung 2, eine Injektionsflüssigkeit mit hohem Druck (beispielsweise 200 bar) eingepreßt. Die unter diesem hohen Druck stehende Injektionsflüssigkeit reißt nicht nur die Sollbruchstellen 14 auf und ermöglicht es der Injektionsflüssigkeit nach außen in die abzudichtenden Fugen zu treten, auch über den Trennschlitz 13 wird die Einlage 7 mit ihrer Außenseite 8 fest an die Auflageebene gedrückt. Auf diese Weise können nachträglich auftretende Dichtungsmängel effektiv behoben werden.This seal is installed on a construction site in the manner that was initially discussed in connection with the previously known constructions. The two ends of the seal are led out of the formwork. This seal can also be used in rainy weather because, as the illustration shows, the insert 7 made of swellable material is spaced from the contact surface, here represented by the imaginary plane 10, by the sealing lips 12. If the concrete is filled to erect the wall, its weight rests on the seal and thereby presses the sealing lips 12 flat and thus the insert 7 against the contact surface, the insert 7 now starting to swell when it wets through this contact with the contact surface becomes. If it is subsequently determined that the existing structural joint could not be adequately sealed by this seal, for example because the concrete introduced has an excessive shrinkage, then an injection liquid is used in this seal, namely in the recess 2, using known devices high pressure (for example 200 bar). The injection liquid under this high pressure not only tears open the predetermined breaking points 14 and enables the injection liquid to step outside into the joints to be sealed, the insert 7 is also pressed with its outer side 8 firmly against the support plane via the separating slot 13. In this way, subsequent sealing defects can be effectively remedied.

Die erfindungsgemäße Dichtung ist nicht nur einfacher aufgebaut als die eingangs erwähnten Konstruktionen, sie ist trotz des vereinfachten Aufbaues hinsichtlich der ihr zugedachten Funktion erheblich effizienter.The seal according to the invention is not only of simpler construction than the constructions mentioned at the beginning, it is considerably more efficient in terms of the function intended for it, despite the simplified construction.
