Abstract
Description
Die Erfindung betrifft einen Abdichtungsaufbau mit einer Abdichtungsschicht als Isolierung und einem zwischen dieser und der Nutz- und Verschleißschicht liegenden Isolierschutzmaterial.The invention relates to a sealing structure with a sealing layer as insulation and an insulating protective material lying between this and the wear and wear layer.
Auf die letzte bzw. oberste Abdichtungslage der Abdichtungsschicht eines Abdichtungsaufbaus von Dächern, insbesondere Flachdächern, sowie von Balkonen, Terrassen und Parkdecks wird im allgemeinen eine Nutz- oder Verschleißschicht aufgebracht. Diese besteht je nach Nutzung wahlweise aus:A wear or wear layer is generally applied to the last or uppermost sealing layer of the sealing layer of a sealing structure for roofs, in particular flat roofs, as well as for balconies, terraces and parking decks. Depending on the usage, this consists of:
Betonplatten, Keramikplatten oder ähnlichem, Ortbetontafeln, Kies, Sand oder Substratschichten für Begrünungen.Concrete slabs, ceramic slabs or the like, in-situ concrete slabs, gravel, sand or substrate layers for greening.
Derartige Nutz- oder Verschleißschichten bestehen, wie die vorliegenden Beispiele zeigen, meist aus harten Materialien, die zudem oft scharfkantig sind und schädigende statische und dynamische Kräfte auf die Abdichtung übertragen können.Such wear or wear layers, as the present examples show, mostly consist of hard materials, which are also often sharp-edged and can transmit damaging static and dynamic forces to the seal.
Es ist Regel der Technik, daß Schutzschichten aus Isolierschutzmaterial zwischen der Abdichtungsschicht und der Nutz- und Verschleißschicht eines Abdichtungsaufbaus eingebaut werden. Ein solcher Schutz, wie er sich in den letzten Jahren immer mehr eingebürgert hat, wird konventionellerweise durch eine sogenannte Bautenschutzmatte/Bahn erzielt, die auf die letzte bzw. oberste Abdichtungslage aufgelegt wird, bevor die Nutz- und Verschleißschicht aufgebracht wird. So bildet sie eine mechanisch schützende abpuffernde Zwischenlage zwischen den Abdichtungslagen und den Nutz- und Verschleißschichten. Derartige Bautenschutzplatten/matten haben eine Dicke zwischen 6 bis 20 mm und bestehen aus polyurethangebundenem Kunststoff oder Gummigranulat. Sie werden von Spezialfirmen im Block oder auf einem Band hergestellt und sind verhältnismäßig teuer. Diese Bautenschutzplatten/matten werden als Bahnen in Rollenform oder Plattenform angeliefert.It is the rule of technology that protective layers of insulating protective material are installed between the sealing layer and the wear and tear layer of a sealing structure. Such protection, as has become more and more common in recent years, is conventionally achieved by a so-called building protection mat / membrane, which is placed on the last or topmost sealing layer before the wear and tear layer is applied. In this way it forms a mechanically protective buffering intermediate layer between the sealing layers and the wear and tear layers. Such building protection panels / mats have a thickness between 6 to 20 mm and consist of polyurethane-bonded plastic or rubber granulate. They are manufactured in block or on tape by specialist companies and are relatively expensive. These building protection panels / mats are delivered as sheets in roll form or plate form.
Die Aufgabe derartiger Bautenschutzplatten/matten als Isolierschutzmaterial besteht, genauer gesagt, darin, beim Aufbringen der Nutz- oder Verschleißschichten Stöße, Kantenpressungen und Punktbelastungen aufzufangen bzw. abzupuffern, die die Abdichtungslagen verletzen und zu Undichtigkeiten führen könnten. Außerdem sollen derartige Bautenschutzplatten/matten im Langzeitverhalten das Durchdrücken von scharfkantigem Kies, Steinen, Betonplattenkanten und ähnlichem verhindern, da ein solcher ständiger Druck die Unversehrtheit der Abdichtungslagen stark gefährdet.The task of such building protection panels / mats as insulation protection material, more precisely, is to absorb or buffer shocks, edge pressures and point loads when the wear or wear layers are applied, which could damage the sealing layers and lead to leaks. In addition, such building protection panels / mats should prevent the pressing through of sharp-edged gravel, stones, concrete slab edges and the like in long-term behavior, since such constant pressure severely endangers the integrity of the sealing layers.
Die bisher als Isolierschutzmaterial bekannten Bautenschutzplatten/matten sind relativ steif und unhandlich und erfordern einen verhältnismäßig hohen Kunststoff- bzw. Gummigranulataufwand, damit sie ihre Funktion als mechanische Schutzschicht über Abdichtungsschichten ausreichend erfüllen können. Außerdem sind sie selbst für Abdichtungszwecke nicht geeignet, da sie porös, d.h. wasserdurchlässig sind.The building protection plates / mats known hitherto as insulation protection material are relatively stiff and bulky and require a relatively high amount of plastic or rubber granulate, so that they can adequately fulfill their function as a mechanical protective layer via sealing layers. In addition, they are not suitable even for sealing purposes because they are porous, i.e. are permeable to water.
Die Abdichtungsfunktion ist jedoch erwünscht, wenn man Bautenschutz-Bahnen vielseitiger einsetzen will. Die Lagerhaltung vieler Materialien wird gemindert und Produktionskosten werden gesenkt.However, the sealing function is desirable if you want to use building protection sheeting in a more versatile way. The storage of many materials is reduced and production costs are reduced.
Aus dem DE-U-89 03 704 ist eine bituminöse Dachbahn mit einer beidseitig mit Bitumen beschichteten Trägereinlage und einer die Rutschfestigkeit der Dachbahn erhöhenden Armierung bekannt, worin die Armierung ein auf der Oberseite der Dachbahn haftendes Gitter und/oder ein sichtbare Erhöhungen und Vertiefungen in der Dachbahnoberfläche hervorrufendes grobkörniges Material ist, welches in das Bitumen eingebettet ist. Das grobkörnige Material kann ein grobkörniges Mehl aus Kunststoff, Gummi bzw. Kautschuk, Mineral oder dergleichen und/oder ein grobkörniger Sand sein. In dieser Dachbahn sind die Körner des grobkörnigen Materials (Granulat) vollständig in der Bitumenschicht eingebettet, indem das Granulat in das Bitumen gemischt und mit diesem gemeinsam auf die Trägereinlage aufgetragen wird. Diese Bitumen und Granulat aufweisende Materialschicht besteht infolgedessen zu einem erheblichen Anteil aus Bitumen. Zweck dieser Maßnahme ist es, eine Materialschicht zu schaffen, die wesentlich aus Bitumen besteht und die sichtbaren Erhöhungen und Vertiefungen auf der Oberfläche derart aufweist, daß die Bitumenoberfläche in ihrer Rutschfestigkeit beachtlich verbessert wird und diese Bitumenoberfläche vorzugsweise eine stärkere Verankerung eines - ebenfalls die Rutschfestigkeit beträchtlich erhöhenden - Gitters ermöglicht. Diese Dachbahn, die einen sofortigen Schutz des Holzwerkstoffs des Dachs gewährleisten soll, wird auf die tragende Dachunterkonstruktion aus Holzschalung aufgenagelt und besitzt daher als Trägereinlage eine perforierbare Trägereinlage, die durch harte und scharfkantige Materialien einer Nutz- und Verschleißschicht perforiert werden kann, so daß sich diese Dachbahn schon deswegen nicht als Isolierschutzmaterial in einem Abdichtungsaufbau der eingangs genannten Art eignet.From DE-U-89 03 704 a bituminous roofing membrane with a bituminous support insert and a reinforcement which increases the slip resistance of the roofing membrane is known, wherein the reinforcement is a grid adhering to the top of the roofing membrane and / or a visible elevation and depression in the coarse-grained material that causes the roofing membrane surface and is embedded in the bitumen. The coarse-grained material can be a coarse-grained flour made of plastic, rubber or rubber, mineral or the like and / or a coarse-grained sand. In this roofing membrane, the grains of the coarse-grained material (granulate) are completely embedded in the bitumen layer by mixing the granulate into the bitumen and applying it together with the carrier insert. As a result, this layer of material containing bitumen and granules consists to a large extent of bitumen. The purpose of this measure is to create a material layer which consists essentially of bitumen and which has visible elevations and depressions on the surface in such a way that the bitumen surface is considerably improved in its slip resistance and this bitumen surface preferably has a stronger anchorage - also the slip resistance is considerable elevating - grid allows. This roofing membrane that is instant To protect the wood material of the roof, is nailed to the supporting roof substructure made of wooden formwork and therefore has a perforated support insert as a support insert, which can be perforated by hard and sharp-edged materials of a wear and tear layer, so that this roofing membrane alone does not therefore serve as an insulating protection material suitable in a sealing structure of the type mentioned.
Aus der DE-B-1 151 108 ist eine wärmedämmende Abdeckung für Gebäudedächer bekannt, die wenigstens eine Schicht aus bitumierter Dachpappe umfaßt, auf deren Unterseite grobkörniger expandierter Kork angebracht ist. Dieser grobkörnige expandierte Kork hat die hauptsächliche Aufgabe, Ventilationszwischenräume zwischen der Unterlage dieser Abdeckung und der bitumierten Dachpappe sicherzustellen und dient, wie in der DE-B 1 151 108 beschrieben ist, dazu, bisher vorgesehene Steinchenbestreuungen auf der Unterseite der Dachpappe zu ersetzen. Eine solche Abdeckung eignet sich jedoch nicht als Isolierschutzmaterial zwischen einer üblichen Abdichtungschicht und einer aus harten und scharfkantigen Materialien bestehenden Nutz- oder Verschleißschicht.From DE-B-1 151 108 a heat-insulating cover for building roofs is known, which comprises at least one layer of bituminized roofing paper, on the underside of which coarse-grained expanded cork is attached. This coarse-grained expanded cork has the main task of ensuring ventilation gaps between the base of this cover and the bituminized roofing felt and, as described in DE-B 1 151 108, serves to replace previously provided stone sprinkling on the underside of the roofing felt. However, such a cover is not suitable as an insulating protective material between a conventional sealing layer and a wear or wear layer consisting of hard and sharp-edged materials.
Weiter ist aus der GB-A-1 032 964 eine flexible, wasserfeste Membrane bekannt, die eine faserige Basis oder einen faserigen Träger umfaßt, die bzw. der auf wenigstens einer Seite mit einer wasserfesten Zusammensetzung beschichtet ist, in deren Oberflächenschichten vorstehende Mineralteilchen eingebettet sind, wobei sich ein Film aus synthetischem Polymer über die die Mineralteilchen enthaltende äußere Oberfläche der Membrane erstreckt, wobei des der Zweck des Films aus synthetischem Polymer ist, zu bewirken, daß sich das Granulat, das von der Witterung "abgewettert" wird, besser hält (transparente Be schichtung). Diese bekannte Membrane ist eine Abdichtungslage und keine Isolierschutzbahn. Die Herstellung geschieht beispielsweise so, daß ein mit Bitumen imprägniertes Jutegewebe mit oxydiertem Bitumen , welches einen hohen Anteil Schiefer enthält (z.B. 35 Gew.-%), beschichtet und im noch heißen Zustand mit Sand bestreut wird. Diese Membrane kann ebenfalls durch harte und scharfkantige Materialien einer Nutz- oder Verschleißschicht perforiert werden und ist daher auch nicht als Isolierschutzmaterial in dem eingangs genannten Abdichtungsaufbau geeignet.Furthermore, GB-A-1 032 964 discloses a flexible, waterproof membrane which comprises a fibrous base or a fibrous carrier which is coated on at least one side with a waterproof composition, in the surface layers of which protruding mineral particles are embedded , with a film of synthetic polymer extending over the outer surface of the membrane containing the mineral particles, the purpose of the film of synthetic polymer being to cause the granules which are "weathered" by the weather to hold better ( transparent be layering). This well-known membrane is a sealing layer and not an insulating protective sheet. The production takes place, for example, in such a way that a jute fabric impregnated with bitumen is coated with oxidized bitumen, which contains a high proportion of slate (for example 35% by weight), and is sprinkled with sand while it is still hot. This membrane can also be perforated by hard and sharp-edged materials of a wear or wear layer and is therefore not suitable as an insulating protection material in the sealing structure mentioned at the beginning.
Aufgabe der Erfindung ist dem demgegenüber insbesondere, einen Abdichtungsaufbau mit einer Abdichtungsschicht als Isolierung und einem zwischen dieser und der Nutz- und Verschleißschicht liegenden Isolierschutzmaterial zur Verfügung zu stellen, bei welchem Isolierschutzmaterial das Verhältnis zwischen Materialaufwand und mechanischer Schutzwirkung gegen Perforationen durch statische und dynamische Kräfte auf die Abdichtungsschicht möglichst optimal ist, und das handlich verarbeitet werden kann.In contrast, the object of the invention, in particular, is to provide a sealing structure with a sealing layer as insulation and an insulating protective material lying between this and the wear and wear layer, in which insulating protective material the relationship between material expenditure and mechanical protective action against perforations by static and dynamic forces is established the sealing layer is as optimal as possible, and that can be processed easily.
Diese Aufgabe wird mit einem Abdichtungsaufbau der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß das Isolierschutzmaterial wenigstens eine Schutzmaterialschicht umfaßt, die im wesentlichen aus Granulat aus elastischem Natur- und/oder Kunststoff hergestellt und durch ein Klebemittel auf eine Unterlage ein- oder beidseitig aufgebracht ist, wobei das Granulat durch Einstreuen in das Klebemittel aufgebracht ist, und wobei die Unterlage perforationsfest bzw. -widerstandsfähig ist.This object is achieved according to the invention with a sealing structure of the type mentioned at the outset in that the insulating protective material comprises at least one protective material layer which is essentially produced from granules of elastic natural and / or plastic and is applied to an underlay on one or both sides by an adhesive, wherein the granules are applied by sprinkling in the adhesive, and wherein the base is perforation-resistant or resistant.
Durch die perforationsfeste bzw. -widerstandsfähige Unterlage wird einerseits die Menge an Granulat aus elastischem Natur- und/oder Kunststoff, im Gegensatz zu marktüblichen Bautenschutzplatten/bahnen wesentlich vermindert, und andererseits wird die Schutzwirkung von Abdichtungen gegen statische und dynamische Einwirkungen voll erreicht, so daß insgesamt ein ausgezeichnetes Verhältnis zwischen Materialaufwand und Abdichtungsschutzwirkung erzielt wird.Due to the perforation-resistant or resistant underlay, on the one hand the amount of granulate made of elastic natural and / or plastic is significantly reduced, in contrast to commercially available building protection panels / sheets, and on the other hand the protective effect of seals against static and dynamic effects is fully achieved, so that overall, an excellent ratio between material expenditure and sealing protection effect is achieved.
In Weiterentwicklung der Erfindung ist der Abdichtungsaufbau so ausgebildet, daß die aus Granulat bestehende Schutzmaterialschicht mittels klebendem Abdichtungsmaterial auf die perforationsfeste bzw. dehn- und reißfeste Unterlage aufgebracht ist.In a further development of the invention, the sealing structure is designed such that the protective material layer consisting of granules is applied to the perforation-resistant or stretch-resistant and tear-resistant base by means of adhesive sealing material.
Auf diese Weise wird auf einer oder beiden Seiten der perforationsfesten, dehn- und reißfesten Unterlage eine Abdichtungsschicht aufgebracht, welche dem Isolierschutzmaterial in dem Abdichtungsaufbau nach der Erfindung zusätzlich zu ihrer Schutzfunktion Abdichtungseigenschaften verleiht. Dadurch wird nicht nur die Abdichtungsfunktion der darunterliegenden Abdichtungslagen unterstützt, sondern dieses Isolierschutzmaterial eröffnet die Möglichkeit einer vielseitigeren Anwendbarkeit. Es kann auch für Abdichtungszwecke und im Fußbodenbereich als Abdichtungs- und Schutzbahn eingesetzt werden.In this way, a sealing layer is applied to one or both sides of the perforation-resistant, stretch-resistant and tear-resistant base, which gives the insulating protective material in the sealing structure according to the invention, in addition to its protective function, sealing properties. This not only supports the sealing function of the underlying sealing layers, but this insulation protection material opens up the possibility of a more versatile application. It can also be used for waterproofing purposes and in the floor area as a waterproofing and protective membrane.

Ein Verfahren zur Herstellung des Isolierschutzmaterials des erfindungsgemäßen Abdichtungsaufbaus zeichnet sich dadurch aus, daß eine perforationsfeste, reiß- und dehnfähige Unterlage, die vorzugsweise bahnförmig ist, ein- oder beidseitig mit einem Kleber mit Abdichtungseigenschaften belegt bzw. beschichtet wird.

Um eine besonders gute Verankerung des Granulats in dem klebenden Material und der/den dichtenden Deckschichten zu erreichen, wird das Verfahren bevorzugt so ausgeführt, daß das Granulat zur optimalen Haftung nach dem Einstreuen in das Klebemittel eingewalzt wird.In order to achieve particularly good anchoring of the granules in the adhesive material and the sealing cover layers, the process is preferably carried out in such a way that the granules are rolled into the adhesive for optimum adhesion after being sprinkled on.
Weiter kann zur Erzielung eines besonders guten Zusammenhalts des Granulats, wie oben erwähnt, das Granulat nach der Beschichtung bzw. dem Einstreuen mit einem klebenden Material bzw. Klebstoff übersprüht bzw. eingesprüht werden. Zum Einsprühen bzw. Übersprühen soll vorzugsweise das gleiche Klebemittel verwendet werden, mit dem auch die perforationsfeste bzw. reiß- und dehnfähige Unterlage/Einlage vor dem Aufbringen des Granulats ein- oder beidseitig belegt bzw. beschichtet wird.Furthermore, in order to achieve particularly good cohesion of the granules, as mentioned above, the granules can be sprayed or sprayed with an adhesive material or adhesive after coating or sprinkling. For spraying or overspraying, the same adhesive should preferably be used with which the perforation-resistant or tearable and stretchable underlay / insert is coated or coated on one or both sides before the granulate is applied.
