Abstract

The lining for collection troughs, collection spaces or the like made of concrete having at least one expansion joint consists of a plastic coating covering the entire surface above the surface of the concrete. In order to allow the arrangement of an expansion joint and to rule out associated cracks in the coating in the case of a plastic coating whose elasticity in the cured state is extremely small, a layer (9) made of plastic is arranged in a depression (3) which is formed on both sides of the expansion joint (2) and is open upwards, which layer has an upwardly directed curve (8) above the expansion joint (2), and the depression (3) is filled with formation of a joint (10) up to above the curve (8) with a curable material, and the coating (11), extending approximately up to the joint (10), is connected integrally to the layer (9) in the edge region of the depression (3). <IMAGE>

Description

Die Erfindung bezieht sich auf einen chemisch beständigen, flüssigkeitsdichten Belag für Auffangwannen, Auffangräume oder dgl. aus Beton mit mindestens einer Dehnungsfuge, be­stehend aus einer vollflächigen, oberhalb der Betonoberflä­che befindlichen Beschichtung aus Kunststoff.The invention relates to a chemically resistant, liquid-tight covering for collecting trays, collecting rooms or the like. Made of concrete with at least one expansion joint, consisting of a full-surface coating of plastic located above the concrete surface.

Zum Schutz der Umwelt, insbesondere von Boden und Grundwasser, ist für Anlagen, in denen wassergefährdende Stoffe gelagert oder umgeschlagen werden, der Bau von Auffangwannen bzw. Auf­fangräumen vorgeschrieben. Derartige Auffangwannen bzw. Auf­fangräume werden normalerweise aus Beton hergestellt. Beton selbst ist nicht ausreichend flüssigkeitsdicht, so daß die Be­tonoberfläche durch eine besondere Beschichtung abgedichtet werden muß. Eine Beschichtung, die auch gegen organische Löse­mittel, Öle, Chlorkohlenwasserstoffe und andere organische Ver­bindungen beständig ist, besteht beispielsweise aus einem mit einer Glasfasermatte laminierten Furanharz.To protect the environment, especially soil and groundwater, the construction of collecting trays or collecting rooms is mandatory for systems in which water-polluting substances are stored or handled. Such collecting trays or collecting rooms are usually made of concrete. Concrete itself is not sufficiently liquid-tight, so that the concrete surface must be sealed with a special coating. A coating that is also resistant to organic solvents, oils, chlorinated hydrocarbons and other organic compounds consists, for example, of a furan resin laminated with a glass fiber mat.

Die Bau- und Prüfgrundsätze für Beschichtungen von Beton-, Putz- und Estrichflächen an Auffangwannen und Auffangräumen des Instituts für Bautechnik schreiben vor, daß eine solche Beschichtung Risse bis 0,2 mm dauerhaft überbrücken muß. Um Spannungen in Estrich- oder Betonflächen, die insbesondere beim Aushärten und bei thermischen Einflüssen auftreten, zu vermeiden, müssen Estrich- oder Betonflächen ab einer gewissen Größe eine Dehnungsfuge aufweisen, die sich über die gesamte Höhe bzw. Dicke des Estriches bzw. des Betons erstreckt. Der­artige Dehnungsfugen werden beispielsweise durch das Einsetzen von Streifen aus geschäumtem Polystyrol gebildet und haben eine Breite von etwa 2,0 - 5,0 cm. Derartige Dehnungsfugen lassen sich jedoch durch einen Kunststoff, beispielsweise laminiertes Furanharz, dessen Elastizität im ausgehärteten Zustand äußerst gering ist, nicht überbrücken. Aus diesem Grunde wurde bei der­artig beschichteten Auffangwannen bzw. Auffangräumen bisher davon abgesehen, eine Dehnungsfuge anzuordnen. Dies führt ab einer gewissen. Grundfläche zu Spannungen im Beton, die ihrer­seits die Rißbildung in der Beschichtung nicht ausschließt. Da­mit wird eine solche Beschichtung und damit die Auffangwanne bzw. der Auffangraum unbrauchbar.The building and testing principles for coatings on concrete, plaster and screed surfaces on collecting basins and collecting rooms of the Institute of Building Technology stipulate that such a coating must permanently bridge cracks of up to 0.2 mm. In order to avoid stresses in screed or concrete surfaces, which occur in particular during curing and thermal influences, screed or concrete surfaces must have an expansion joint from a certain size that extends over the entire height or thickness of the screed or concrete . Such expansion joints are formed, for example, by inserting strips of foamed polystyrene and have one Width of about 2.0 - 5.0 cm. However, such expansion joints cannot be bridged by a plastic, for example laminated furan resin, the elasticity of which is extremely low in the hardened state. For this reason, it has so far been avoided to arrange an expansion joint in collecting trays or collecting rooms coated in this way. This leads to a certain. Base area for tension in the concrete, which in turn does not exclude the formation of cracks in the coating. Such a coating and thus the collecting trough or the collecting space are therefore unusable.

Der Erfindung liegt nun die Aufgabe zugrunde, einen chemisch beständigen, flüssigkeitsdichten Belag für Auffangwannen, Auf­fangräume oder dergleichen aus Beton, der aus einer Beschich­tung aus Kunststoff besteht, so auszugestalten, daß auch die Anordnung einer Dehnungsfuge möglich und damit verbundene Risse in der Beschichtung ausgeschlossen sind.The invention is based on the object, a chemically resistant, liquid-tight covering for sumps, collecting rooms or the like made of concrete, which consists of a coating of plastic, so that the arrangement of an expansion joint is possible and associated cracks in the coating are excluded .

Zur Lösung dieser Aufgabe wird bei dem Belag gemäß der Erfin­dung vorgeschlagen, daß in einer beidseitig der Dehnungsfuge geformten, nach oben offenen Mulde eine Schicht aus einem Kunststoff angeordnet ist, die über der Dehnungsfuge eine nach oben gerichtete Wölbung aufweist und daß die Mulde unter Bil­dung einer Fuge bis oberhalb der Wölbung mit einem aushärtbaren Werkstoff ausgefüllt und die sich annähernd bis zur Fuge er­streckende Beschichtung im Randbereich der Mulde einstückig mit der Schicht verbunden ist. Durch diese Ausbildung treten in der Schicht im Bereich der Wölbung keine Zugspannungen, sondern nur geringfügige Biegespannungen auf, die zu keinerlei Beschädi­gungen der Schicht und damit der Beschichtung führen.To solve this problem, it is proposed in the covering according to the invention that a layer of plastic is arranged in an upwardly open recess formed on both sides of the expansion joint, which has an upward curvature above the expansion joint and that the recess to form a The joint is filled with a hardenable material up to the arch and the coating that extends almost to the joint in the edge region of the trough is integrally connected to the layer. As a result of this design, tensile stresses do not occur in the layer in the area of the curvature, but only slight bending stresses which do not lead to any damage to the layer and thus to the coating.

Weitere Merkmale eines Belages gemäß der Erfindung sind in den Ansprüchen 2 - 17 offenbart.Further features of a covering according to the invention are disclosed in claims 2-17.

Die Erfindung wird nachfolgend anhand in einer Zeichnung darge­stellter Ausführungsbeispiele näher erläutert. Dabei zeigen

  • Fig. 1 einen Schnitt durch einen Belag gemäß der Erfindung und
  • Fig. 2 einen Schnitt durch eine weitere Ausbildung eines Be­lages.
The invention is explained in more detail below with reference to exemplary embodiments shown in a drawing. Show
  • Fig. 1 shows a section through a covering according to the invention and
  • Fig. 2 shows a section through a further formation of a covering.

In den Figuren 1 und 2 der Zeichnung ist eine Betonplatte 1 ausschnittsweise dargestellt, die im dargestellten Bereich mit einer Fuge 2 versehen ist. Über dieser Fuge 2 befindet sich eine nach oben offene Mulde 3, die symmetrisch zur Dehnungsfu­ge 2 angeordnet ist und beispielsweise einen trapezförmigen Querschnitt aufweist. Nachdem die Betonoberfläche zum Ausgleich von vorhandenen Unebenheiten abgespachtelt wurde, wird auf den Boden 4 der Mulde 3 eine Elastomerfolie 5, beispielsweise durch Klebung, befestigt. Bedarfsweise kann vor dem Aufbringen des Klebers eine Grundierung aufgetragen werden. Sodann wird auf diese Elastomerfolie 4 und mittig über der Dehnungsfuge 2 eine Schnur 6 aus beispielsweise elastischem Schaumstoff gelegt, die in den dargestellten Ausführungsbeispielen elliptischen Quer­schnitt besitzt. Bedarfsweise kann diese Schnur 6 auch einen anderen Querschnitt aufweisen. Sodann wird die gesamte Mulde 3 sowie die übrige Oberfläche der Betonplatte 1 mit einer aufkleb­baren Elastomerfolie 7 versehen, die über der Schnur 6 eine Wöl­bung 8 bildet.1 and 2 of the drawing, a concrete slab 1 is shown in detail, which is provided with a joint 2 in the area shown. Above this joint 2 is an upwardly open trough 3, which is arranged symmetrically to the expansion joint 2 and has, for example, a trapezoidal cross section. After the concrete surface has been filled to compensate for any unevenness, an elastomer film 5 is attached to the bottom 4 of the recess 3, for example by gluing. If necessary, a primer can be applied before applying the adhesive. Then a cord 6 made of, for example, elastic foam is placed on this elastomer film 4 and in the middle above the expansion joint 2, which has an elliptical cross section in the exemplary embodiments shown. If necessary, this cord 6 can also have a different cross section. Then the entire trough 3 and the rest of the surface of the concrete slab 1 are provided with an adhesive elastomer film 7 which forms a curvature 8 above the cord 6.

Im Anschluß an diese Elastomerfolie 8 wird die Mulde 5 mit einer glasfaserverstärkten Kunstharzbeschichtung 9 versehen, die sich gemäß dem Ausführungsbeispiel der Fig. 1 über die Mul­de 3 hinaus um einen vorbestimmten Betrag auf die obere Fläche der Betonplatte 1 erstreckt und die in gleicher Weise wie die Elastomerfolie 8 über der Schnur 6 eine Wölbung 8 bildet. Im Anschluß daran wird die Mulde 3 unter Bildung einer Fuge 10 mit einem Gemisch aus Furanharz und keramischen Zusätzen, beispiels­weise keramischen Platten, ausgefüllt, wobei sich die Oberfläche dieser Füllung annähernd mit der durch die Elastomerfolie 7 be­deckten Oberfläche der Betonplatte 1 in einer Ebene befindet. Sodann wird auf die gesamte Oberfläche der Betonplatte 1 eine Beschichtung 11 aus einem laminierten Furanharz aufgebracht, die sich mit den aus der Mulde 3 herausragenden Endbereichen 12 der Schicht 9 einstückig verbindet und in diesem Ausführungsbeispiel kurz vor der Fuge 10, beispielsweise in der Innenecke von Win­kelprofilschienen 13 aus rostfreiem Stahl, endet. Jeweils ein Schenkel dieser Winkelprofilschienen 13 begrenzt die Fuge 10. Auf den so ausgebildeten Belag können bedarfsweise keramische Platten 14 aufgebracht werden, die mittels eines Furanharzkit­tes 15 verlegt und ebenfalls mittels Furanharz verfugt sind. Die Fuge 10 wird anschließend mit einer elastischen Fugenmasse ausgefüllt. Bedarfsweise kann der Bereich der Schicht 9 über der Schnur 6 mittels eines Bandes 16 aus leicht verformbaren und weitgehend chemisch beständigem Werkstoff, der keine Haf­tung mit der Schicht 9 eingeht, beispielsweise aus Kupfer, ab­gedeckt sein, durch das die Wölbung 8 beim Ausfüllen der Mulde 3 geschützt wird. Die Winkelprofilschienen 13 können über be­sondere Pratzen 17 in der Füllung der Mulde 3 verankert sein.Following this elastomer film 8, the trough 5 is provided with a glass fiber-reinforced synthetic resin coating 9 which, according to the exemplary embodiment in FIG. 1, extends beyond the trough 3 by a predetermined amount onto the upper surface of the concrete slab 1 and which forms a curvature 8 above the cord 6 in the same way as the elastomer film 8. Subsequently, the trough 3 is filled with a mixture of furan resin and ceramic additives, for example ceramic plates, forming a joint 10, the surface of this filling being approximately in one plane with the surface of the concrete plate 1 covered by the elastomer film 7. Then a coating 11 made of a laminated furan resin is applied to the entire surface of the concrete slab 1, which connects in one piece with the end regions 12 of the layer 9 protruding from the trough 3 and in this exemplary embodiment shortly before the joint 10, for example in the inner corner of angle profile rails 13 stainless steel ends. One leg of each of these angular profile rails 13 delimits the joint 10. If necessary, ceramic plates 14 can be applied to the covering formed in this way, which are laid by means of a furan resin cement 15 and are also jointed by means of furan resin. The joint 10 is then filled with an elastic joint compound. If necessary, the area of the layer 9 above the cord 6 can be covered by means of a tape 16 made of easily deformable and largely chemically resistant material which does not adhere to the layer 9, for example made of copper, through which the curvature 8 when filling the trough 3 is protected. The angle rails 13 can be anchored in the filling of the trough 3 via special claws 17.

Bei dem Ausführungsbeispiel der Fig. 2 endet die Schicht 9 aus laminiertem Furanharz an der Oberkante der Mulde 3. Nach dem Ausfüllen der Mulde 3 wird auch hier auf die gesamte Ober­fläche der Betonplatte 1 eine Beschichtung 11 aus laminiertem Furanharz aufgebracht, die sich muldenförmig in die Mulde 3 erstreckt und ebenfalls an den Innenecken von Winkelprofil­schienen 13 anliegt. Hier verbindet sich die Beschichtung 11 im oberen Bereich der Mulde 3 mit der Schicht 9, so daß ein ge­schlossener, flüssigkeitsdichter und chemisch beständiger Be­lag entsteht. Bei diesem Ausführungsbeispiel werden mittels eines Verlegekittes 15 keramische Platten 14 so innerhalb des oberen Bereiches der Mulde 3 verlegt, daß dieselben mit der Oberfläche der Beschichtung 11 in einer Ebene abschließen. Auf den übrigen Bereich der Beschichtung 11 werden hier keine kera­mischen Platten 14 verlegt.In the embodiment of FIG. 2, the layer 9 of laminated furan resin ends at the upper edge of the trough 3. After the trough 3 has been filled, a coating 11 of laminated furan resin is also applied to the entire surface of the concrete slab 1, which coating trough-shaped in the Trough 3 extends and also abuts the inner corners of angle rails 13. The coating 11 joins here in the upper area of the trough 3 with the layer 9, so that a closed, liquid-tight and chemically resistant covering is formed. In this exemplary embodiment, ceramic tiles 14 are laid within the upper region of the depression 3 by means of a laying cement 15 in such a way that they terminate in one plane with the surface of the coating 11. No ceramic plates 14 are laid here on the remaining area of the coating 11.

Bedarfsweise können die zwischen den Elastomerfolien 7,8 und der Schnur 6 verbleibenden Räume 18, die etwa dreieckigen Querschnitt aufweisen, mit einer elastischen Masse ausgefüllt werden. Ferner ist es möglich, zwischen der Elastomerfolie 7 und der Beschichtung 11 bzw. der Schicht 9 aus laminiertem Furanharz eine elektrisch leitende Spachtelschicht vorzusehen, die es ermöglicht, daß die Beschichtung 11 aus laminiertem Fu­ranharz mittels eines Funkenprüfgerätes auf Porenfreiheit über­prüft werden kann. Für den Fall, daß keine keramischen Plat­ten 14 verwendet werden, kann die Beschichtung 11 mittels ei­ner besonderen Spachtelmasse, die mineralische, schuppenför­mige Füllstoffe enthält, abgeschlossen werden. Dadurch wird der Diffusionswiderstand erheblich gesteigert.If necessary, the spaces 18 remaining between the elastomer films 7, 8 and the cord 6, which have an approximately triangular cross section, can be filled with an elastic mass. Furthermore, it is possible to provide an electrically conductive filler layer between the elastomer film 7 and the coating 11 or the layer 9 made of laminated furan resin, which enables the coating 11 made of laminated furan resin to be checked for freedom from pores by means of a spark tester. In the event that no ceramic plates 14 are used, the coating 11 can be finished off by means of a special filler that contains mineral, scale-like fillers. This significantly increases the diffusion resistance.

In Abänderung der erläuterten Ausführungsbeispiele kann die Beschichtung 11 und die Schicht 9 auch aus Polyesterharz, Vinylesterharz, Phenolharz oder Epoxidharz bestehen und mit anderen Fasern, beispielsweise Kohlenstoffasern, laminiert bzw. verstärkt sein.In a modification of the exemplary embodiments explained, the coating 11 and the layer 9 can also consist of polyester resin, vinyl ester resin, phenolic resin or epoxy resin and can be laminated or reinforced with other fibers, for example carbon fibers.
