Definitions
- the invention relates to a waterproof sealing membrane, which is particularly suitable for use in building and civil engineering.
- plastic films as a sealing material in such a way that the sheet-like films are applied overlapping to a substrate and a tape made of self-adhesive profiled sealant, e.g. B. made of butyl rubber, between the foils.
- the adhesive tape required for this is inserted for the purpose of transport and handling when laying between two layers of a removable protective film, for example made of silicone paper.
- a removable protective film for example made of silicone paper.
- From DE-A 2510162 it is known to provide rubber sealing sheets with an adhesive tape already during their manufacture; an adhesive tape is attached to a longitudinal edge on the top and another adhesive tape on the opposite edge on the bottom.
- the adhesive tapes can be covered with silicone paper.
- Plastic sealing sheets can also be welded with the help of solvents or by heating.
- a sealing membrane known from DE-GM 79 07 342 consists of a bitumen layer which is covered on the underside with a non-woven material and on the top with sand, a blank, uncovered zone being provided for connection in the edge region. Heating is required to weld the sheets.
- sealing materials consist of a flexible film with a coating of a self-adhesive sealing compound.
- the preferred material for the sealant is a bitumen / rubber compound. This material too is laid overlapping in strips in such a way that the self-adhesive sealant adheres to the surface to be sealed and is protected by the cover film. In the overlap area, the self-adhesive sealing compound of the upper sheet lies on the cover sheet of the lower sheet, so that bonding of the sheet to the sheet is achieved.
- the sheets are not completely smooth, e.g. B. due to unevenness of the substrate, or in the case of tensions due to temperature fluctuations, however, incomplete bonding between the sealing compound and the film or the formation of capillaries through which water can penetrate can occur in the overlap region.
- US-A-39 00 102 discloses a sealing sheet which consists of sealing compound between a carrier film and a protective film made of silicone paper, the latter being removed before the material is used. Therefore, the sealing material is firmly bonded to the substrate with all the disadvantages associated with it. Due to the cold flow of the sealing compound under pressure, the compound can be squeezed out a little laterally. However, such a cold river cannot be controlled, so that this supernatant does little to ensure a safe connection of the tracks to one another. The connection of the overlapping sheets is therefore essentially between the self-adhesive sealant of the respective upper sheet and the carrier film of the respective lower sheet.
- the invention is based on the object of developing a sealing membrane which not only has the advantages of the conventional materials, but moreover can be laid particularly conveniently and without problems and thereby provides a completely watertight layer.
- a reliably tight, homogeneous connection is to be achieved in the overlap area of the sealing sheets, laying on substrates of all kinds is possible, and application of further materials by gluing is not excluded.
- the invention relates to a sealing membrane for use in building construction and civil engineering on the basis of a plastic-elastic self-adhesive sealing compound which is enclosed between two flexible layers, the upper layer not covering the sealing compound in the region of one longitudinal side and thus a protrusion for the overlapping connection of the webs, which is characterized in that the lower layer, which is not removably connected to the sealing compound, does not cover the sealing compound in the region of the opposite longitudinal side and thus also forms an overhang for the overlapping connection of the webs.
- sealant can only be bonded to sealant in those areas where sealant has escaped beyond the edge of the carrier film due to cold flow, ie appropriate pressure application, which will only be the case in places.
- the upper layer in the area of one long side and the lower layer in the area of the other long side leave a narrow strip of the sealing compound as a fixing edge, which is arranged on the side opposite the overlap projection.
- Bitumen / rubber mixtures are particularly suitable as sealing compounds, whereby their excellent temperature properties are important: They can still be bent by 180 ° down to - 30 ° C and, on the other hand, do not show any flow up to temperatures of + 80 ° C. H. sufficient stability. It is possible to lay the sealing membrane at temperatures around 0 ° C, since the self-adhesive properties of the sealing compound are then sufficient for a homogeneous connection.
- a suitable sealing compound for the geomembrane according to the invention consists, for. B. from 40 to 80 parts by weight of bitumen (softening point 60 to 100 ° C according to DIN 1995), 15 to 45 parts of aromatic oil and 5 to 15 parts of rubber, for. B. a styrene / butadiene copolymer.
- the layer thickness for the self-adhesive sealant is between approximately 0.4 and 3 mm, preferably between 1 and 2 mm, in particular approximately 1.5 mm.
- Films made from polyvinyl chloride or fluoride, EPDM rubber, butyl rubber, chloroprene or natural rubber are suitable.
- the thickness of the foils is between 40 and 500, preferably between 60 and 200, in particular around 100 ⁇ m. When using laminated foils, for example, two foils, each 50 11 m thick, can be joined together.
- Metal foils are also suitable for certain purposes, although they have a lower elasticity.
- the sealing membrane according to the invention can also be constructed in such a way that the upper flexible layer consists of a film and the lower one consists of a non-woven fabric or a plastic film laminated with a non-woven fabric. In this way, a sealing membrane is obtained which can be glued to a substrate much better than a plastic film with the aid of adhesive, which can be particularly desirable if the sealing membranes cannot be weighed down after installation, for example with the aid of a gravel fill.
- the lower flexible layer of the sealing membrane according to the invention consists of a mesh fabric, so that by pushing against the substrate, sticking through (self-adhesive in places with the substrate) can be achieved. In all of these cases, the homogeneous and tight connection is achieved in the seam or overlap area between the webs in that one self-adhesive side area lies over another.
- the sealing sheets according to the invention can be manufactured and used in different widths.
- a favorable width is about 0.9 to 1.2 m.
- the width of the self-adhesive area on the upper surface along one side and on the lower surface along the opposite side should be up to 10 cm, e.g. B. about 2 to 8, advantageously 4 to 7, but in particular about 7 to 8 cm.
- the overlap area can have a smaller width because a particularly homogeneous and tight connection is achieved by the meeting of two areas with self-adhesive sealant.
- the optionally provided fixing edge is normally much narrower than the opposite overhang for the overlapping connection of the webs.
- the fixing edge accordingly preferably has a width of approximately 0.5 to 2, in particular approximately 1 cm.
- the fixing edge is also covered with a protective film, for example silicone paper. It is used to fix the sheets on the sub-floor without additional aids, which makes laying considerably easier.
- the fixing edge lying on the top enables subsequent layers, e.g. B. of protective fleeces or the like.
- the self-adhesive areas of the sealing membrane according to the invention are advantageously covered with a removable protective film which is removed when the material is laid. Siliconized paper is preferably used for this.
- the sealing sheet according to the invention made of self-adhesive plastic-elastic sealing compound between two flexible layers is characterized in particular by the fact that the upper layer to a certain extent floats on the lower one, which considerably favors a compensation of mechanical or thermal stresses.
- the production of the sealing membrane according to the invention with a self-adhesive sealing compound enclosed between two flexible layers can be carried out in a particularly advantageous manner in such a way that a roll mill with two cooled rolls, the two layer materials, eg. B. two films are fed from above in a funnel shape, with a silicone paper strip being carried overlapping in a somewhat larger width in each edge region.
- the sealing compound is placed in the funnel formed by the two supplied films and the silicone paper and the layer thickness of the sealing compound and at the same time that of the finished sealing membrane are controlled by the distance between the two rollers.
- the area on the two long sides, used for gluing the sealing membrane during later overlapping laying, is obtained in that the film does not reach the edge of one side, but is replaced by the removable silicone paper.
- the 1 consists of a self-adhesive sealant 11 between two films 12 and 13.
- the upper film 12 does not extend to the long side 17, so that a strip of the self-adhesive sealant is exposed in the area of this side in the longitudinal direction.
- the lower film 13 does not extend to the opposite longitudinal side 16, so that an exposed self-adhesive area is present in the area of this side on the underside.
- the self-adhesive areas on both sides on the upper and lower surface of the sealing membrane are each covered with a removable protective film (e.g. made of silicone paper) 14 and 15, which are removed when the membranes are laid.
- the protective film preferably protrudes slightly from the side so that it can be removed more easily.
- the films 13 'and 12' opposite the films 12 and 13 leave a narrow strip 18, 19 of the sealing compound 11 free. This creates a fixing edge, which considerably facilitates the laying of the sheets.
- the fixing edge 19 on the underside causes adhesion to the substrate, while the fixing edge 18 on the upper side causes additional layers to be fixed.
- the protective films 14, 15 prevent the material from sticking in the area of the fixing edges during transport and storage.

Description
Die Erfindung betrifft eine wasserdichte Dichtungsbahn, welche sich insbesondere zur Verwendung im Hoch- und Tiefbau eignet.The invention relates to a waterproof sealing membrane, which is particularly suitable for use in building and civil engineering.
Es ist bereits bekannt, Folien aus Kunststoff in der Weise als Dichtungsmaterial zu verwenden, daß man die bahnförmigen Folien überlappend auf einen Untergrund aufbringt und zur Verbindung der Bahnen im Überlappungsbereich ein Band aus selbstklebender profilierter Dichtungsmasse, z. B. aus Butylkautschuk, zwischen die Folien legt. Das hierfür benötigte Klebeband ist zum Zweck des Transports und der Handhabung bei der Verlegung zwischen zwei Schichten einer abziehbaren Schutzfolie, beispielsweise aus Silikonpapier, eingelegt. Aus der DE-A 2510162 ist es bekannt, Dichtungsbahnen aus Gummi bereits bei ihrer Herstellung mit einem Klebeband zu versehen ; dabei ist ein Klebeband an einem Längsrand an der Oberseite und ein weiteres Klebeband an dem gegenüberliegenden Rand an der Unterseite angebracht. Die Klebebänder können mit Silikonpapier abgedeckt sein.It is already known to use plastic films as a sealing material in such a way that the sheet-like films are applied overlapping to a substrate and a tape made of self-adhesive profiled sealant, e.g. B. made of butyl rubber, between the foils. The adhesive tape required for this is inserted for the purpose of transport and handling when laying between two layers of a removable protective film, for example made of silicone paper. From DE-A 2510162 it is known to provide rubber sealing sheets with an adhesive tape already during their manufacture; an adhesive tape is attached to a longitudinal edge on the top and another adhesive tape on the opposite edge on the bottom. The adhesive tapes can be covered with silicone paper.
Dichtungsbahnen aus Kunststoff können auch mit Hilfe von Lösungsmitteln oder durch Erhitzen verschweißt werden.Plastic sealing sheets can also be welded with the help of solvents or by heating.
Die Verlegung derartiger Dichtungsbahnen ist sehr umständlich und schon bei geringsten Ungenauigkeiten beim Einlegen des Klebebandes oder beim Verschweißen wird im Überlappungsbereich keine dichte Verbindung erhalten.The laying of such sealing sheets is very cumbersome and even with the slightest inaccuracies when inserting the adhesive tape or when welding, no tight connection is obtained in the overlap area.
Eine aus dem DE-GM 79 07 342 bekannte Dichtungsbahn besteht aus einer Bitumenschicht, die auf der Unterseite mit einem Vliesmaterial und auf der Oberseite mit Sand abgedeckt ist, wobei zur Verbindung im Randbereich eine blanke, nicht abgedeckte Zone vorgesehen ist. Zum Verschweißen der Bahnen muß erhitzt werden.A sealing membrane known from DE-GM 79 07 342 consists of a bitumen layer which is covered on the underside with a non-woven material and on the top with sand, a blank, uncovered zone being provided for connection in the edge region. Heating is required to weld the sheets.
Aus der DE-A 1621 939 sind ferner Dichtungsmaterialien bekannt, welche aus einer flexiblen Folie mit einer Beschichtung aus einer selbstklebenden Dichtungsmasse bestehen. Das bevorzugte Material für die Dichtungsmasse ist eine Bitumen/Kautschukmasse. Auch dieses Material wird bahnweise überlappend in der Weise verlegt, daß die selbstklebende Dichtungsmasse an dem abzudichtenden Untergrund haftet und durch die Deckfolie geschützt ist. Im Überlappungsbereich liegt die selbstklebende Dichtungsmasse der oberen Bahn auf der Deckfolie der unteren Bahn, so daß eine Verklebung von Masse auf Folie erreicht wird.From DE-A 1621 939 sealing materials are also known which consist of a flexible film with a coating of a self-adhesive sealing compound. The preferred material for the sealant is a bitumen / rubber compound. This material too is laid overlapping in strips in such a way that the self-adhesive sealant adheres to the surface to be sealed and is protected by the cover film. In the overlap area, the self-adhesive sealing compound of the upper sheet lies on the cover sheet of the lower sheet, so that bonding of the sheet to the sheet is achieved.
Bei nicht vollständig glatter Verlegung der Bahnen, z. B. wegen Unebenheiten des Untergrundes, oder bei Spannungen aufgrund von Temperaturschwankungen kann es jedoch im Überlappungsbereich zu einer unvollständigen Verklebung zwischen Dichtungsmasse und Folie bzw. zu einer Bildung von Kapillaren kommen, durch welche Wasser eindringen kann.If the sheets are not completely smooth, e.g. B. due to unevenness of the substrate, or in the case of tensions due to temperature fluctuations, however, incomplete bonding between the sealing compound and the film or the formation of capillaries through which water can penetrate can occur in the overlap region.
Aus der US-A 41 72830 ist es bekannt, ein Dichtungsmaterial der vorstehend angegebenen Art so abzuwandeln, daß auf die Bitumen/Kautschukmasse eine an der Außenseite silikonisierte Polyethylenfolie als Deckschicht aufgebracht wird, welche einen etwa 10 cm breiten Randbereich nicht abdeckt ; letzterer ist mit einer abziehbaren Schutzfolie bedeckt. Auf diese Weise wird bei überlappender Verlegung der Bahnen eine bessere Verbindung erreicht, doch kann auf die silikonisierte Oberfläche kein weiteres Material aufgeklebt werden. Es kommt hinzu, daß sich derartige bitumenbeschichtete Dichtungsbahnen nicht überall einsetzen lassen ; sie sind beispielswiese nicht für eine Verlegung auf Wärmedämm-Materialien aus Polystyrol geeignet, welche in zunehmendem Maße sowohl im Innenausbau als auch für Dachabdeckungen eingesetzt werden.From US-A 41 72830 it is known to modify a sealing material of the type specified above in such a way that a polyethylene film siliconized on the outside is applied as a covering layer to the bitumen / rubber composition, which does not cover an approximately 10 cm wide edge area; the latter is covered with a removable protective film. In this way, a better connection is achieved when the sheets are laid overlapping, but no further material can be glued to the siliconized surface. In addition, bitumen-coated waterproofing membranes of this type cannot be used everywhere; for example, they are not suitable for laying on thermal insulation materials made of polystyrene, which are being used to an increasing extent both in interior fittings and for roof coverings.
Die US-A-39 00 102 offenbart eine Dichtungsbahn, welche aus Dichtungsmasse zwischen einer Trägerfolie und einer Schutzfolie aus Silikonpapier besteht, wobei letztere vor Einsatz des Materials abgezogen wird. Es erfolgt deshalb eine feste Verklebung des Abdichtungsmaterials mit dem Untergrund mit allen damit verbundenen Nachteilen. Aufgrund des kalten Flusses der Dichtungsmasse unter Druckeinwirkung kann die Masse seitlich etwas herausgepreßt werden. Ein derartiger kalter Fluß kann jedoch nicht kontrolliert werden, so daß dieser Überstand zu einer sicheren Verbindung der Bahnen untereinander wenig beiträgt. Die Verbindung der überlappend verlegten Bahnen erfolgt deshalb im wesentlichen zwischen der selbstklebenden Dichtungsmasse der jeweils oberen Bahn und der Trägerfolie der jeweils unteren Bahn.US-A-39 00 102 discloses a sealing sheet which consists of sealing compound between a carrier film and a protective film made of silicone paper, the latter being removed before the material is used. Therefore, the sealing material is firmly bonded to the substrate with all the disadvantages associated with it. Due to the cold flow of the sealing compound under pressure, the compound can be squeezed out a little laterally. However, such a cold river cannot be controlled, so that this supernatant does little to ensure a safe connection of the tracks to one another. The connection of the overlapping sheets is therefore essentially between the self-adhesive sealant of the respective upper sheet and the carrier film of the respective lower sheet.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Dichtungsbahn zu entwickeln, welche nicht nur die Vorteile der herkömmlichen Materialien aufweist, sondern sich darüber hinaus besonders bequem und problemlos verlegen läßt und dabei eine völlig wasserdichte Schicht liefert. Insbesondere soll mit Hilfe der Erfindung eine zuverlässig dichte, homogene Verbindung im Überlappungsbereich der Dichtungsbahnen erzilet werden, eine Verlegung auf Substraten aller Art möglich und ein Aufbringen weiterer Materialien durch Verkleben nicht ausgeschlossen sein.In contrast, the invention is based on the object of developing a sealing membrane which not only has the advantages of the conventional materials, but moreover can be laid particularly conveniently and without problems and thereby provides a completely watertight layer. In particular, with the aid of the invention, a reliably tight, homogeneous connection is to be achieved in the overlap area of the sealing sheets, laying on substrates of all kinds is possible, and application of further materials by gluing is not excluded.
Gegenstand der Erfindung ist eine Dichtungsbahn zur Verwendung im Hoch- und Tiefbau auf Basis einer plastisch-elastischen selbstklebenden Dichtungsmasse, die zwischen zwei flexiblen Schichten eingeschlossen ist, wobei die obere Schicht die Dichtungsmasse im Bereich einer Längsseite nicht abdeckt und so einen Überstand für die überlappende Verbindung der Bahnen bildet, welche dadurch gekennzeichnet ist, daß die nicht abziehbar mit der Dichtungsmasse verbundene untere Schicht die Dichtungsmasse im Bereich der gegenüberliegenden Längsseite nicht abdeckt und damit ebenso einen Überstand für die überlappende Verbindung der Bahnen bildet.The invention relates to a sealing membrane for use in building construction and civil engineering on the basis of a plastic-elastic self-adhesive sealing compound which is enclosed between two flexible layers, the upper layer not covering the sealing compound in the region of one longitudinal side and thus a protrusion for the overlapping connection of the webs, which is characterized in that the lower layer, which is not removably connected to the sealing compound, does not cover the sealing compound in the region of the opposite longitudinal side and thus also forms an overhang for the overlapping connection of the webs.
Man erreicht so über den ganzen Überlappungsbereich der Bahnen eine zuverlässige Verklebung durch Kontakt von Dichtungsmasse mit Dichtungsmasse. Bei der OS-A-39 00 102 kann dagegen eine Verklebung von Dichtungsmasse mit Dichtungsmasse nur in den Bereichen erfolgen, wo durch kalten Fluß, d. h. entsprechende Druckanwendung Dichtungsmasse über den Rand der Trägerfolie hinausgetreten ist, was nur stellenweise der Fall sein wird.This way you can reach all over lapping area of the webs reliable bonding by contact of sealant with sealant. With OS-A-39 00 102, on the other hand, sealant can only be bonded to sealant in those areas where sealant has escaped beyond the edge of the carrier film due to cold flow, ie appropriate pressure application, which will only be the case in places.
Gemäß einer bevorzugten Ausführungsform lassen die obere Schicht im Bereich der einen Längsseite und die untere Schicht im Bereich der anderen Längsseite einen schmalen Streifen der Dichtungsmasse als Fixierungsrand frei, welcher jeweils auf der dem Überlappungsüberstand gegenüberliegenden Seite angeordnet ist.According to a preferred embodiment, the upper layer in the area of one long side and the lower layer in the area of the other long side leave a narrow strip of the sealing compound as a fixing edge, which is arranged on the side opposite the overlap projection.
Als Dichtungsmasse sind Bitumen/Kautschukmischungen besonders geeignet, wobei ihre hervorragenden Temperatureigenschaften wichtig sind : Sie lassen sich noch bis - 30 °C um 180° biegen und zeigen andererseits bis zu Temperaturen von + 80 °C noch kein Fließen, d. h. eine ausreichende Standfestigkeit. Eine Verlegung der Dichtungsbahnen ist bereits bei Temperaturen um 0 °C möglich, da die selbstklebenden Eigenschaften der Dichtungsmasse dann für eine homogene Verbindung schon ausreichen. Eine geeignete Dichtungsmasse für die erfindungsgemäße Dichtungsbahn besteht z. B. aus 40 bis 80 Gewichtsteilen Bitumen (Erweichungspunkt 60 bis 100 °C nach DIN 1995), 15 bis 45 Teilen aromatisches Öl und 5 bis 15 Teilen Kautschuk, z. B. einem Styrol/Butadien-Copolymer. Die Schichtdicke für die selbstklebende Dichtungsmasse liegt zwischen etwa 0,4 und 3 mm, vorzugsweise zwischen 1 und 2 mm, insbesondere bei etwa 1,5 mm.Bitumen / rubber mixtures are particularly suitable as sealing compounds, whereby their excellent temperature properties are important: They can still be bent by 180 ° down to - 30 ° C and, on the other hand, do not show any flow up to temperatures of + 80 ° C. H. sufficient stability. It is possible to lay the sealing membrane at temperatures around 0 ° C, since the self-adhesive properties of the sealing compound are then sufficient for a homogeneous connection. A suitable sealing compound for the geomembrane according to the invention consists, for. B. from 40 to 80 parts by weight of bitumen (softening point 60 to 100 ° C according to DIN 1995), 15 to 45 parts of aromatic oil and 5 to 15 parts of rubber, for. B. a styrene / butadiene copolymer. The layer thickness for the self-adhesive sealant is between approximately 0.4 and 3 mm, preferably between 1 and 2 mm, in particular approximately 1.5 mm.
Als Folien eignen sich solche aus Polyvinylchlorid oder -fluorid, EPDM-Kautschuk, Butylkautschuk, Chloropren oder Naturkautschuk, d. h. Materialien mit einer ausreichenden Elastizität, die selbst bei größerer mechanischer oder thermischer Beanspruchung nicht reißen, insbesondere aber Polyolefinfolien, d. h. Folien aus Polyethylen oder Polyethylen/Polypropylen, die mono- oder biaxial gestreckt sein können. Die Stärke der Folien liegt zwischen 40 und 500, vorzugsweise zwischen 60 und 200, insbesondere bei etwa 100 µm. Bei Verwendung von laminierten Folien können beispielsweise zwei Folien von je 50 11m Stärke miteinander verbunden sein.Films made from polyvinyl chloride or fluoride, EPDM rubber, butyl rubber, chloroprene or natural rubber are suitable. H. Materials with sufficient elasticity that do not tear even with greater mechanical or thermal stress, but in particular polyolefin films, i. H. Films made of polyethylene or polyethylene / polypropylene, which can be stretched mono- or biaxially. The thickness of the foils is between 40 and 500, preferably between 60 and 200, in particular around 100 μm. When using laminated foils, for example, two foils, each 50 11 m thick, can be joined together.
Für bestimmte Zwecke sind auch Metallfolien geeignet, obwohl sie eine geringere Elastizität besitzen.Metal foils are also suitable for certain purposes, although they have a lower elasticity.
Besonders günstig sind mit Metallen, z. B. mit Aluminium oder Kupfer bedampfte Kunststoffolien oder laminierte Metall/Kunststoffolien, z. B. aus einer Aluminiumfolie zwischen zwei Polyethylenfolien. Derartige Folien zeichnen sich insbesondere durch ihre Wasserdampfdichtigkeit aus, was sie z. B. zur Verwendung im Kühlhausbau besonders geeignet macht.Are particularly cheap with metals such. B. with aluminum or copper vapor-coated plastic films or laminated metal / plastic films, for. B. from an aluminum foil between two polyethylene foils. Such films are particularly characterized by their water vapor tightness, which they z. B. makes particularly suitable for use in cold store construction.
Die erfindungsgemäße Dichtungsbahn kann auch so aufgebaut sein, daß die obere flexible Schicht aus einer Folie und die untere aus einem Faservlies oder einer mit einem Faservlies kaschierten Kunststoffolie besteht. Man erhält auf diese Weise eine Dichtungsbahn, welche sich wesentlich besser als eine Kunststoffolie mit Hilfe von Klebstoff mit einem Untergrund verkleben läßt, was insbesondere dann wünschenswert sein kann, wenn die Dichtungsbahnen nach dem Verlegen nicht beschwert werden können, beispielsweise mit Hilfe einer Kiesschüttung. Eine weitere Möglichkeit besteht darin, daß die untere flexible Schicht der erfindungsgemäßen Dichtungsbahn aus einem Gittergewebe besteht, so daß durch Andrücken an den Untergrund ein Durchkleben (stellenweise Selbstverklebung mit dem Untergrund) erreicht werden kann. Im Naht- bzw. Überlappungsbereich zwischen den Bahnen wird in allen diesen Fällen die homogene und dichte Verbindung jeweils dadurch erreicht, daß ein selbstklebender Seitenbereich über einem anderen liegt.The sealing membrane according to the invention can also be constructed in such a way that the upper flexible layer consists of a film and the lower one consists of a non-woven fabric or a plastic film laminated with a non-woven fabric. In this way, a sealing membrane is obtained which can be glued to a substrate much better than a plastic film with the aid of adhesive, which can be particularly desirable if the sealing membranes cannot be weighed down after installation, for example with the aid of a gravel fill. Another possibility is that the lower flexible layer of the sealing membrane according to the invention consists of a mesh fabric, so that by pushing against the substrate, sticking through (self-adhesive in places with the substrate) can be achieved. In all of these cases, the homogeneous and tight connection is achieved in the seam or overlap area between the webs in that one self-adhesive side area lies over another.
Die Dichtungsbahnen gemäß Erfindung können in unterschiedlichen Breiten hergestellt und eingesetzt werden. Eine günstige Breite liegt bei etwa 0,9 bis 1,2 m. Die Breite des selbstklebenden Bereiches an der oberen Fläche längs der einen Seite und an der unteren Fläche längs der gegenüberliegenden Seite soll bis zu 10 cm, z. B. etwa 2 bis 8, günstigerweise 4 bis 7, insbesondere aber etwa 7 bis 8 cm betragen. Gegenüber den Materialien der DE-OS 16 21 939 ist es ein zusätzlicher Vorteil der erfindungsgemäßen Dichtungsbahn, daß der Überlappungsbereich eine geringere Breite aufweisen kann, weil durch das Aufeinandertreffen von zwei Bereichen mit selbstklebender Dichtungsmasse eine besonders homogene und dichte Verbindung erreicht wird.The sealing sheets according to the invention can be manufactured and used in different widths. A favorable width is about 0.9 to 1.2 m. The width of the self-adhesive area on the upper surface along one side and on the lower surface along the opposite side should be up to 10 cm, e.g. B. about 2 to 8, advantageously 4 to 7, but in particular about 7 to 8 cm. Compared to the materials of DE-OS 16 21 939, it is an additional advantage of the sealing membrane according to the invention that the overlap area can have a smaller width because a particularly homogeneous and tight connection is achieved by the meeting of two areas with self-adhesive sealant.
Der gegebenenfalls vorgesehene Fixierungsrand ist normalerweise wesentlich schmäler als der gegenüberliegende Überstand für die überlappende Verbindung der Bahnen. Der Fixierungsrand hat demgemäß vorzugsweise eine Breite von etwa 0,5 bis 2, insbesondere etwa 1 cm. Der Fixierungsrand ist ebenfalls mit einer Schutzfolie, beispielsweise einem Silikonpapier abgedeckt. Er dient einmal zur Fixierung der Bahnen auf dem Untergrund ohne zusätzliche Hilfsmittel, was die Verlegung beträchtlich erleichtert. Der an der Oberseite liegende Fixierungsrand ermöglichst zum anderen ein Festlegen nachfolgender Schichten, z. B. von Schutzvliesen oder dergleichen.The optionally provided fixing edge is normally much narrower than the opposite overhang for the overlapping connection of the webs. The fixing edge accordingly preferably has a width of approximately 0.5 to 2, in particular approximately 1 cm. The fixing edge is also covered with a protective film, for example silicone paper. It is used to fix the sheets on the sub-floor without additional aids, which makes laying considerably easier. On the other hand, the fixing edge lying on the top enables subsequent layers, e.g. B. of protective fleeces or the like.
Für die Lagerung und den Transport werden die selbstklebenden Bereiche der erfindungsgemäßen Dichtungsbahn günstigerweise mit einer abziehbaren Schutzfolie abgedeckt, welche beim Verlegen des Materials entfernt wird. Bevorzugt findet hierfür silikonisiertes Papier Verwendung.For storage and transport, the self-adhesive areas of the sealing membrane according to the invention are advantageously covered with a removable protective film which is removed when the material is laid. Siliconized paper is preferably used for this.
Die erfindungsgemäße Dichtungsbahn aus selbstklebender plastisch-elastischer Dichtungsmasse zwischen zwei flexiblen Schichten zeichnet sich insbesondere dadurch aus, daß die obere Schicht gewissermaßen auf der unteren schwimmt, was einen Ausgleich von mechanischen oder thermischen Spannungen beträchtlich begünstigt. Darüber hinaus vereinigt dieses Material in sich praktisch die vorteilhaften Eigenschaften einer einfachen Kunststoffolie und einer mit einer Dichtungsmasse beschichteten Kunststoffolie : Es kann auch dort verlegt werden, wo die direkte Aufbringung von Bitumen- oder Klebemassen, sei es durch Gießen, Streichen oder in Form von Bitumen-Trägerfolien, nicht möglich ist ; gegenüber einfachen Folien weist das Material selbstheilende Eigenschaften auf, weil die Dichtungsmasse selbst Löcher in beiden Deckfolien verschließt, wie sie beispielsweise beim Durchtreten von einzelnen Kiessteinen beim Verlegen des Materials entstehen können.The sealing sheet according to the invention made of self-adhesive plastic-elastic sealing compound between two flexible layers is characterized in particular by the fact that the upper layer to a certain extent floats on the lower one, which considerably favors a compensation of mechanical or thermal stresses. In addition, this unites Material in itself the advantageous properties of a simple plastic film and a plastic film coated with a sealing compound: It can also be installed where the direct application of bitumen or adhesive compounds, whether by pouring, brushing or in the form of bitumen carrier films, is not is possible ; Compared to simple foils, the material has self-healing properties because the sealing compound itself closes holes in both cover foils, such as can occur when individual gravel stones pass through when laying the material.
Die Verwendung von dünnen Einzelfolien gibt der Gesamtbahn eine große Flexibilität, die besser ist als diejenige von dicken Abdichtungsbahnen aus einer Einzelfolie mit vergleichbarer Festigkeit.The use of thin individual foils gives the entire web great flexibility, which is better than that of thick sealing webs made of a single foil with comparable strength.
Die Herstellung der erfindungsgemäßen Dichtungsbahn mit einer zwischen zwei flexiblen Schichten eingeschlossenen selbstklebenden Dichtungsmasse kann in besonders günstiger Weise so erfolgen, daß einem Walzenstuhl mit zwei gekühlten Walzen die beiden Schichtmaterialien, z. B. zwei Folien von oben trichterförmig zugeführt werden, wobei in jeweils einem Randbereich ein Silikonpapierstreifen überlappend in etwas größerer Breite mitgeführt wird. Die Dichtungsmasse wird in den von den beiden zugeführten Folien und dem Silikonpapier gebildeten Trichter gegeben und die Schichtdicke der Dichtungsmasse und zugleich auch die der fertigen Dichtungsbahn werden durch den Abstand der beiden Walzen voneinander gesteuert. Der zum .Verkleben der Dichtungsbahn beim späteren überlappenden Verlegen dienende Bereich an den beiden Längsseiten wird dadurch erhalten, daß hier an je einer Seite die Folie nicht bis zum Rand reicht, sondern durch das abziehbare Silikonpapier ersetzt ist.The production of the sealing membrane according to the invention with a self-adhesive sealing compound enclosed between two flexible layers can be carried out in a particularly advantageous manner in such a way that a roll mill with two cooled rolls, the two layer materials, eg. B. two films are fed from above in a funnel shape, with a silicone paper strip being carried overlapping in a somewhat larger width in each edge region. The sealing compound is placed in the funnel formed by the two supplied films and the silicone paper and the layer thickness of the sealing compound and at the same time that of the finished sealing membrane are controlled by the distance between the two rollers. The area on the two long sides, used for gluing the sealing membrane during later overlapping laying, is obtained in that the film does not reach the edge of one side, but is replaced by the removable silicone paper.
Zur näheren Erläuterung der Erfindung sotten die beiliegenden Zeichnungen dienen ; es zeigen
- Figur 1 eine perspektivische geschnittene Darstellung der erfindungsgemäßen Dichtungsbahn,
- Figur 2 einen Schnitt durch zwei überlappend verlegte Dichtungsbahnen gemäß einer weiteren Ausführungsform der Erfindung.
- FIG. 1 shows a perspective sectional illustration of the sealing membrane according to the invention,
- Figure 2 shows a section through two overlapping sealing sheets according to another embodiment of the invention.
Die Dichtungsbahn der Figur 1 besteht aus einer selbstklebenden Dichtungsmasse 11 zwischen zwei Folien 12 und 13. Die obere Folie 12 reicht nicht bis zur Längsseite 17, so daß im Bereich dieser Seite in Längserstreckung ein Streifen der selbstklebenden Dichtungsmasse frei liegt. In ähnlicher Weise reicht die untere Folie 13 nicht bis zu der gegenüberliegenden Längsseite 16, so daß im Bereich dieser Seite an der Unterseite ein freiliegender selbstklebender Bereich vorhanden ist. Die selbstklebenden Bereiche an den beiden Seiten auf der oberen bzw. unteren Fläche der Dichtungsbahn sind jeweils mit einer abziehbaren Schutzfolie (z. B. aus Silikonpapier) 14 bzw. 15 abgedeckt, welche beim Verlegen der Bahnen entfernt werden. Die Schutzfolie steht vorzugsweise seitlich etwas über, damit sie sich leichter entfernen läßt.1 consists of a self-
Beim überlappenden Verlegen der Bahnen liegt die Seite 16 über der Seite 17, so daß die von den Folien 12 bzw. 13 nicht abgedeckten Bereiche der selbstklebenden Dichtungsmasse 11 unmittelbar aufeinandertreffen und zu einer homogenen, dauerhaften und wasserdichten Verbindung führen. Wie Figur 2 zeigt, wird eine voll befriedigende Verbindung schon bei einer Überlappung der Bahnen erreicht, bei welcher die klebenden Schichten zu einem wesentlichen Teil direkt aufeinanderliegen, zum Teil aber auch eine Verklebung zwischen Klebeschicht und Folie stattfindet.When the sheets are laid overlapping, the
Die den Folien 12 und 13 gegenüberliegenden Folien 13' und 12' lassen bei der in Figur 2 gezeigten Ausführungsform einen schmalen Streifen 18, 19 der Dichtungsmasse 11 frei. Dadurch wird ein Fixierungsrand gebildet, der die Verlegung der Bahnen beträchtlich erleichtert. Der Fixierungsrand 19 an der Unterseite bewirkt eine Haftung am Untergrund, während der Fixierungsrand 18 an der Oberseite die Festlegung weiterer Schichten bewirkt. Ein Verkleben des Materials im Bereich der Fixierungsränder bei Transport und Lagerung wird durch die Schutzfolien 14, 15 verhindert.In the embodiment shown in FIG. 2, the films 13 'and 12' opposite the
