Description

Die Erfindung betrifft ein Verfahren zum Verlegen von zumindest an einer Fläche kaltselbstklebenden Bitumenabdichtungsbahnen, bei der man mehrere derartige Bitumenabdichtungsbahnen längs eines Randstreifens einander überlappend mit der kaltselbstklebenden Fläche auf eine abzudichtende Unterlage weisend auf diese auflegt und sie im überlappenden Randstreifen durch gegenseitiges Andrücken miteinander verbindet. Außerdem betrifft die Erfindung eine Bitumenabdichtungsbahn, die zur Durchführung dieses Verfahrens geeignet ist.The invention relates to a method for laying at least at a surface Kaltselbstklebenden bitumen waterproofing membranes, in the several such bituminous sealing sheets along a marginal strip overlap each other with the cold self-adhesive surface indicating a pad to hang on these and she im overlapping margins by mutual pressing together combines. Moreover, the invention relates to a bitumen waterproofing membrane, which is suitable for carrying out this method.

Es sind kaltverklebende Bitumenabdichtungsbahnen bekannt, bei denen die Bitumenmasse durch spezielle Zusätze selbstklebend ausgerüstet ist. Üblicherweise werden diese selbstklebend ausgebildeten Bitumenabdichtungsbahnen mit Trennfolien oder Trennpapieren abgedeckt und erst bei der Verlegung abgezogen. Die Kaltverklebung hat in letzter Zeit sehr an Bedeutung gewonnen, da das Verlegeverfahren schnell, einfach und sauber ist und die Gefahr durch den Umgang mit heißem Bitumen oder mit offener Flamme vermieden werden kann. Allerdings ist der Einsatz von kaltverklebten Bahnen auf trockenes Wetter und trockenen Untergrund begrenzt. Wenn die notwendigen Bedingungen nicht vorliegen, muß in herkömmlicher Weise eine Heißverklebung stattfinden. Bei Bitumenabdichtungsbahnen, die kaltselbstklebend ausgebildet sind, kann jedoch im Randbereich, in dem sich die Bitumenabdichtungsbahnen überlappen, eine solche Wärmebehandlung nicht stattfinden, da die einander überlappenden Bitumenabdichtungsbahnen beim Verlegen bereits miteinander verkleben und somit eine Wärmebehandlung im Überlappungsbereich verhindern.Cold-bonding bituminous sealing sheets are known in which the bituminous compound is self-adhesive with special additives is. Usually, these are self-adhesive Bitumen waterproofing membranes covered with release liners or release papers and only deducted when laying. The cold glueing has Recently, very important because the laying process fast, easy and clean and the danger of dealing with hot bitumen or with an open flame can be avoided. However, the use of cold-glued webs is dry Limited weather and dry ground. If the necessary Conditions are not present, must in a conventional manner a hot bonding occur. For bitumen waterproofing membranes, which are self-adhesive are formed, but can in the edge region in which the Bitumen waterproofing sheets overlap, such a heat treatment not take place because the overlapping bituminous membranes already glue together when laying and thus one Prevent heat treatment in the overlap area.

Aus der EP 0 352 394 A1 ist eine Bitumenabdichtungsbahn bekannt, die in zwei Bereiche aufgeteilt ist, nämlich einen kaltselbstklebenden Bereich und einen schmalen Randstreifen, der wärmeverschweißbar ist. Dieser ist aus einem anderen Material hergestellt als der übrige kaltselbstklebende Bereich. Außerdem erstreckt sich dieser thermisch verschmelzbare Randbereich nicht über den gesamten Überlappungsbereich, sondern nur über etwa den halben Überlappungsbereich, der Überlappungsbereich ist also geteilt ausgebildet. Dadurch ergibt sich eine deutlich erschwerte Herstellung, und es werden auch extrem hohe Anforderungen an die Verlegegenauigkeit gestellt, da beide Teilbereiche des Überlappungsbereiches mit der darunterliegenden Bitumenabdichtungsbahn in Kontakt kommen müssen, der innenliegende kaltselbstklebende Streifen soll nämlich eine spontane Verklebung erzielen, der außen liegende Randstreifen soll dann thermisch zusätzlich verklebt werden.EP 0 352 394 A1 discloses a bituminous waterproofing membrane, which is divided into two areas, namely a Kaltselbstklebenden Area and a narrow edge strip, which is heat-sealable. This is made of a different material than the rest of the self-adhesive Kaltselbstklebende Area. In addition, this thermally fusible extends Edge area not over the entire overlap area, but only about half the overlap area, the Overlap area is thus designed to be shared. This results a much more difficult production, and it is also extremely high Requirements placed on the installation accuracy, since both sub-areas the overlap area with the underlying bitumen waterproofing membrane must come into contact, the internal cold self-adhesive Strip should namely achieve a spontaneous bonding, the outer edge strip is then thermally bonded additionally become.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Verfahren so auszuführen, daß bei der Verlegung von kaltselbstklebenden Bitumenabdichtungsbahnen bei Bedarf in geeigneter Weise eine Verbindung im Überlappungsbereich durch Wärmebehandlung möglich wird, wobei die Anforderungen an die Verlegegenauigkeit nicht allzu hoch sind.It is an object of the invention to carry out a generic method in such a way that in the laying of cold self-adhesive bitumen waterproofing membranes If necessary, a suitable connection in the Overlap area is possible by heat treatment, the Requirements for installation accuracy are not too high.

Diese Aufgabe wird bei einem Verfahren der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß man Bitumenabdichtungsbahnen verwendet, deren kaltselbstklebende Fläche sich über die gesamte Fläche der Bitumenabdichtungsbahnen erstreckt und vor dem Auflegen der Bitumenabdichtungsbahnen auf die Unterlagen einseitig nur im Bereich des gesamten, einen Überlappungsbereich ausbildenden Randstreifens mit einer die kaltselbstklebenden Eigenschaften beseitigenden Abdeckung versehen ist.This object is achieved in a method of the type described above Art according to the invention solved by that bituminous membranes whose self-adhesive surface extends over the entire surface Surface of the bituminous membranes extends and before the Applying the bitumen waterproofing membranes to the underlay on one side only in the area of the whole, forming an overlap area Edge strip having a cold self-adhesive properties Cover is provided.

In dieser Weise ausgestattete Bitumenabdichtungsbahnen verkleben beim Auflegen auf die Unterlage aufgrund der kaltselbstklebenden Eigenschaften in der gewohnten Weise mit der Unterlage, allerdings erfolgt eine solche Verklebung nicht in dem Bereich des Randstreifens, der mit einer Abdeckung versehen ist. Dabei wird eine Bitumenabdichtungsbahn verwendet, die besonders einfach aufgebaut ist, da die Unterseite einheitlich kaltselbstklebend ausgebildet ist. Im Randstreifen, und zwar in dem gesamten den Überlappungsbereich bildenden Randstreifen, werden die kaltselbstklebenden Eigenschaften aufgehoben, sei es durch eine Abstreuung, sei es durch einen aufgelegten Folienstreifen etc.Glue in this way equipped bitumen waterproofing membranes when laying on the surface due to the self-adhesive cold Properties in the usual way with the underlay, however such adhesion does not occur in the region of the marginal strip, which is provided with a cover. This is a bitumen waterproofing membrane used, which is particularly simple, since the bottom is formed uniformly cold self-adhesive. In the border strip, in the entire edge strip forming the overlap area, the self-adhesive properties are canceled it by a scattering, be it by an applied film strip Etc.

Wenn der Verleger beabsichtigt, die einander überlappenden Bitumenabdichtungsbahnen nicht durch eine Kaltselbstverklebung miteinander zu verkleben, sondern durch eine Wärmeverklebung, wird so vorgegangen, daß man die Bitumenabdichtungsbahn in einer Richtung und Reihenfolge verlegt, bei denen der mit einer Abdeckung versehene Randstreifen der oberen Bitumenabdichtungsbahn die darunterliegende Bitumenabdichtungsbahn überlappt, und daß man zumindest die obere der beiden überlappenden Bitumenabdichtungsbahnen im Überlappungsbereich vor dem Zusammendrücken erwärmt und dadurch die Verhinderung der Klebefähigkeit in dem von der Abdeckung überdeckten Randstreifen aufhebt.If the publisher intends to overlap the overlapping bituminous membranes not by a cold self-adhesive together to stick, but by a heat bonding, this is done, that the bitumen waterproofing membrane in one direction and Assigned order in which the provided with a cover Edge strip of the upper bitumen waterproofing membrane underneath Bitumen waterproofing membrane overlaps, and that at least the upper the two overlapping Bitumenabdichtungsbahnen in the overlapping area warmed up before compression and thereby the Prevention of adhesiveness in the cover covered by the cover Edge trim picks up.

Das Vorsehen der Abdeckung bewirkt also, daß der Benutzer die oben liegende Bitumenabdichtungsbahn im Bereich der Überlappung noch von der unteren Bitumenabdichtungsbahn anheben kann, da hier keine spontane Verklebung durch die Kaltselbstklebeeigenschaften erfolgt. Dies ermöglicht eine Wärmebehandlung, beispielsweise durch ein Heißluftgebläse oder durch eine offene Flamme, und diese Wärmebehandlung stellt die Klebefähigkeit des mit der Abdeckung versehenen Randstreifens wieder her, sei es durch Aufschmelzen des Bitumenmaterials, sei es durch thermische Entfernung der Abdeckung, sei es durch eine Kombination beider Maßnahmen.The provision of the cover thus causes the user to use the above lying bitumen waterproofing membrane in the overlap still from the lower bitumen waterproofing membrane, since there is no spontaneous bonding takes place by the cold self-adhesive properties. This allows a heat treatment, for example by a hot air blower or by an open flame, and this heat treatment represents the adhesiveness of the trim strip provided with the cover again, whether by melting the bitumen material, be it by thermal removal of the cover, be it through a Combination of both measures.

Dabei ist es günstig, wenn man den mit einer Abdeckung versehenen Randstreifen der oberen Bitumenabdichtungsbahn zum Erwärmen von der unteren Bitumenabdichtungsbahn abbiegt, um so gezielt eine Wärmebehandlung in dem abgedeckten Randstreifen zu ermöglichen. Da durch die Abdeckung eine Verklebung mit der darunterliegenden Bitumenabdichtungsbahn verhindert wird, ist dies ohne weiteres möglich.It is advantageous if you provided the with a cover Edge strip of the upper bitumen waterproofing membrane for heating the lower bitumen waterproofing membrane turns so as to selectively heat treatment to allow in the covered edge strip. There through the cover a bond with the underlying bitumen waterproofing membrane is prevented, this is easily possible.

Wenn der Benutzer jedoch feststellt, daß die Bedingungen für eine Kaltselbstverklebung vorliegen, wird gemäß einer bevorzugten Ausführungsform der Erfindung so vorgegangen, daß man die Bitumenabdichtungsbahnen in einer Richtung und Reihenfolge verlegt, bei denen der mit einer Abdeckung versehene Randstreifen der oberen Bitumenabdichtungsbahn nicht auf der unteren Bitumenabdichtungsbahn aufliegt, sondern auf der der unteren Bitumenabdichtungsbahn abgewandten Seite auf der Unterlage. In diesem Falle liegt also die obere Bitumenabdichtungsbahn mit einem kaltselbstklebenden Randstreifen an der unteren Bitumenabdichtungsbahn an und kann einfach durch Andrücken mit dieser sicher verklebt werden. Auf der gegenüberliegenden Seite der oberen Bitumenabdichtungsbahn wird durch den mit einer Abdeckung versehenen Streifen zwar diese Bitumenabdichtungsbahn in einem schmalen Randbereich nicht mit der Unterlage klebend verbunden, dies ist jedoch unerheblich, da die Abdichtung zur Unterlage durch die auf diesen Randstreifen auf der oberen Seite aufgelegte nächste Bitumenabdichtungsbahn übernommen wird. Nach den Fachregeln reicht zur Herstellung der Sicherheit gegen Windsog eine Verklebung von 50 % der Fläche aus.However, if the user determines that the conditions for a Kaltselbstverklebung be present, according to a preferred embodiment the invention proceeds so that the bituminous membranes relocated in a direction and order in which the provided with a cover edge strip of the upper bitumen waterproofing membrane not on the lower bitumen waterproofing membrane rests, but facing away from the lower bitumen waterproofing membrane Side on the pad. In this case, so is the upper Bitumen waterproofing membrane with a cold self-adhesive edge strip on the lower bitumen waterproofing membrane and can easily through Pressing with this glue securely. On the opposite Side of the upper bitumen waterproofing membrane is covered with the Although a cover provided strip this bitumen waterproofing membrane Do not stick to the base in a narrow edge area connected, but this is irrelevant, since the seal to the pad by the laid on these margins on the upper side next bitumen waterproofing membrane is taken. According to the specialist rules is sufficient to produce the security against wind suction gluing from 50% of the area.

Die Kaltselbstklebeeigenschaft kann beispielsweise durch Abstreuen des Überlappungsbereichs beseitigt werden. Bei einer Wärmebehandlung wird das umgebende Bitumenmaterial aufgeschmolzen und kann sich somit mit einer darunterliegenden Bitumenabdichtungsbahn verbinden, wobei die Abstreuungspartikel eingebettet werden.The cold self-adhesive property can be, for example, by scattering of the overlap area are eliminated. In a heat treatment The surrounding bitumen material is melted and can thus associate with an underlying bituminous waterproofing membrane, wherein the scattering particles are embedded.

Bei einer anderen Ausführungsform ist vorgesehen, daß die Abdeckung durch Auflegen eines Vlieses oder einer Folie vorgenommen wird. Diese können durch die Wärmeentwicklung beseitigt werden, beispielsweise durch Aufschmelzen, so daß dadurch einerseits die kaltselbstklebende Oberfläche wieder freigelegt wird, andererseits wird die Klebeeigenschaft durch die Erwärmung des Bitumenmaterials erhöht.In another embodiment it is provided that the cover by placing a fleece or a film is made. These can be eliminated by the heat, for example by melting, so that on the one hand the self-adhesive Kaltselbstklebende Surface is exposed again, on the other hand, the adhesive property increased by the heating of the bitumen material.

Der Erfindung liegt auch die Aufgabe zugrunde, eine Bitumenabdichtungsbahn mit mindestens einer kaltselbstklebenden Fläche so auszubilden, daß mit ihr wahlweise eine kaltselbstklebende oder eine warmklebende Stoßverbindung herstellbar ist.The invention is also based on the object, a bitumen waterproofing membrane with at least one self-adhesive surface, that with her optionally a Kaltselbstklebende or a hot glue Butt joint can be produced.

Diese Aufgabe wird bei einer Bitumenabdichtungsbahn der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß sich die kaltselbstklebende Fläche über die gesamte Fläche der Bitumenabdichtungsbahn erstreckt und daß der gesamte, einen Überlappungsbereich ausbildende Randstreifen der kaltselbstklebenden Fläche mit einer Abdeckung versehen ist, die die Kaltselbstklebeeigenschaften der kaltselbstklebenden Fläche beseitigt.This object is achieved with a bituminous membrane of the above described type according to the invention solved in that the self-adhesive Kaltselbstklebende Surface over the entire surface of the bitumen waterproofing membrane extends and that the whole, an overlap area forming edge strips of the self-adhesive Kaltsfläche with a cover provided that the cold self-adhesive properties of the self-adhesive Kaltselfklebenden Surface eliminated.

Dabei ist es günstig, wenn die Abdeckung derart gewählt ist, daß der abgedeckte Randstreifen durch Wärmebehandlung klebend wird.It is advantageous if the cover is selected such that the Covered edge strip is adhesive by heat treatment.

Der Randstreifen kann beispielsweise eine Breite von 4 bis 8 cm aufweisen.The edge strip may for example have a width of 4 to 8 cm.

The following description of preferred embodiments of the invention is used in conjunction with the drawings for further explanation. Show it:

a perspective view of the laid according to Figure 1 bituminous membranes with a one-sided illustration for illustration only lifted bitumen waterproofing membrane and

a view similar to Figure 1 at a Kaltselbstklebenden connection of the adjacent Bitumenabdichtungsbahnen.

Eine Unterlage 1, beispielsweise eine Dachfläche, wird zur Abdichtung mit nebeneinanderliegenden Bitumenabdichtungsbahnen 2 abgedeckt. Diese Bitumenabdichtungsbahnen 2 können beliebig aufgebaut sein, wesentlich ist lediglich, daß eine Fläche, die nachstehend als Unterseite 3 bezeichnet wird, mit einem kaltselbstklebenden Material versehen ist, also mit einem Material, das bei normalen Umgebungstemperaturen mit der Unterlage 1 verklebt, wenn die Bitumenabdichtungsbahn 2 auf diese Unterlage 3 aufgelegt wird.A pad 1, for example, a roof surface, is for sealing with adjacent bitumen waterproofing membranes 2 covered. These bitumen waterproofing membranes 2 can be constructed arbitrarily, is essential merely that a surface, which below as the bottom 3 is designated, with a self-adhesive Kaltselbstklebenden Material is provided, so with a material that at normal ambient temperatures glued to the substrate 1, when the bitumen waterproofing sheet 2 on this pad 3 is launched.

Der übrige Aufbau der Bitumenabdichtungsbahnen kann sehr unterschiedlich sein, es ist möglich, mehrere Bitumenschichten übereinander innerhalb der Bitumenabdichtungsbahn vorzusehen, diese kann auch an der Oberseite kaltselbstklebend ausgebildet sein, sie kann an der Oberseite mit einer Folie abgedeckt sein, etc.The rest of the structure of the bitumen waterproofing membranes can be very different, it is possible several Bitumen layers one above the other within the bitumen waterproofing membrane This can also be applied to the The upper side can be made of self-adhesive cold she can be covered at the top with a foil, etc.

Die Bitumenabdichtungsbahn 2 ist an einer Längsseite in einem Randstreifen 4, der beispielsweise eine Breite zwischen 4 und 6 cm aufweist, mit einer Abdeckung 5 versehen, welche in diesem Randstreifen 4 die kaltselbstklebende Unterseite 3 abdeckt und damit die Kaltselbstklebeeigenschaften des Randstreifens 4 beseitigt. Diese Abdeckung 5 kann beispielsweise eine mineralische Abstreuung sein, es ist jedoch auch die Auflage einer Folie oder eines Vlieses denkbar. Damit wird also die Kaltselbstklebeeigenschaft nur in dem schmalen Randstreifen 4 beseitigt, nicht aber auf der übrigen Unterseite 3.The bituminous sealing sheet 2 is on a longitudinal side in an edge strip 4, for example, a width between 4 and 6 cm, with a cover. 5 provided, which in this edge strip 4, the kaltselbstklebende Bottom 3 covers and thus the cold self-adhesive properties of the edge strip 4 eliminated. This cover 5, for example, a mineral But it is also the edition of one Foil or a nonwoven conceivable. So that is the Cold self-adhesive property only in the narrow border strip 4 eliminated, but not on the rest of the bottom Third

Die in dieser Weise vorbereiteten Bitumenabdichtungsbahnen 2 werden üblicherweise mit auf die Unterseite 3 aufgelegter Abziehfolie geliefert, die in der Zeichnung nicht dargestellt ist.The prepared in this way bitumen waterproofing membranes 2 are usually with on the bottom 3 Applied peel-off foil, which in the drawing not shown.

Beim Verlegen der Bitumenabdichtungsbahnen 2 wird diese Abziehfolie vor dem Verlegen abgezogen, so daß die kaltselbstklebende Unterseite 3 freigelegt wird, anschließend wird die Bitumenabdichtungsbahn 2 auf die Unterlage 1 aufgelegt und durch Andrücken mit dieser kaltselbstklebend verklebt.When laying the bituminous membranes 2 this is Peel off before laying, so that the cold self-adhesive bottom 3 is exposed, then the bituminous sealing sheet 2 is placed on the Pad 1 is applied and by pressing with this cold glued self adhesive.

Die nächste Bitumenabdichtungsbahn wird in der gleichen Weise vorbereitet und dann derart auf die Unterseite 3 aufgelegt, daß der Randstreifen 4 mit der Abdeckung 5 die bereits verlegte Bitumenabdichtungsbahn überlappt. Dies führt einmal dazu, daß diese zweite Bitumenabdichtungsbahn 2 mit der kaltselbstklebenden Unterseite 3 in dem neben der ersten Bitumenabdichtungsbahn 2 angeordneten Bereich mit der Unterlage 1 verklebt wird, zum anderen wird aber eine Verklebung des Randstreifens 4 mit der bereits vorher verlegten und nunmehr unterhalb des Randstreifens 4 liegenden Bitumenabdichtungsbahn 2 verhindert. The next bitumen waterproofing membrane will be in the same Way prepared and then on the bottom 3 placed on the edge strip 4 with the cover. 5 overlaps the already laid bitumen waterproofing membrane. This leads once to this second bitumen waterproofing membrane 2 with the self-adhesive underside 3 in arranged next to the first bituminous sealing sheet 2 Area is glued to the pad 1, for but another is a bonding of the edge strip. 4 with the previously laid and now below of the edge strip 4 lying Bitumenabdichtungsbahn second prevented.

Um in diesem Bereich trotzdem eine dichte Verklebung zu erreichen, ist es daher möglich, den Randstreifen 4 von der darunterliegenden Bitumenabdichtungsbahn 2 anzuheben und aufzufalten, wie es in Figur 1 am rechten Rand der zweiten Bitumenabdichtungsbahn erkennbar ist. In den dadurch entstehenden Zwickel können mit Hilfe einer geeigneten Heizvorrichtung 6 Heißluft oder Flammgase eingeleitet werden, so daß die Unterseite des mit der Abdeckung 5 versehenen Randstreifens 4 aufgeheizt wird. Diese Aufheizung führt dazu, daß die Klebefähigkeit des Randstreifens 4 wiederhergestellt wird, sei es durch Wegschmelzen der folien- oder vliesförmigen Abdeckung, sei es durch Aufschmelzen des Bitumenmaterials, sei es durch eine Kombination beider Maßnahmen.In order to still in this area a tight bond to reach, it is therefore possible, the edge strip 4 of the underlying bituminous membrane 2 lift and unfold, as shown in Figure 1 on the right edge the second bitumen waterproofing membrane is recognizable. In The resulting gusset can with the help of a suitable heating device 6 hot air or flame gases be initiated so that the bottom of the with the Cover 5 provided edge strip 4 is heated. This heating causes the adhesiveness of the Marginal strip 4 is restored, whether through Melting away the foil or fleece-shaped cover, be it by melting the bitumen material, be it through a combination of both measures.

Nach diesem Aufheizvorgang ist es ohne weiteres möglich, den Randstreifen 4 durch Andrücken dauerhaft mit der darunterliegenden Bitumenabdichtungsbahn 2 zu verkleben, und zwar auch bei Bedingungen, die eine Kaltselbstverklebung nicht gestatten.After this heating process, it is easily possible the edge strip 4 by pressing permanently with to bond the underlying bituminous sealing sheet 2, and even under conditions that a cold self-adhesive do not allow.

Die Verlegung der Bitumenabdichtungsbahnen 2 kann aber auch wahlweise in der Weise erfolgen, daß die obere Bitumenabdichtungsbahn 2 nicht mit dem mit einer Abdekkung 5 versehenen Randstreifen 4 auf die darunterliegende Bitumenabdichtungsbahn 2 aufgelegt wird, sondern mit dem gegenüberliegenden Rand, der weiterhin kaltselbstklebend ausgebildet ist. Es ist dadurch möglich, die obere Bitumenabdichtungsbahn 2 in dem überlappenden Randbereich direkt durch Andrücken kaltselbstklebend mit der zuerst verlegten Bitumenabdichtungsbahn 2 zu verbinden, ohne daß die geschilderte Erwärmung des Randbereiches notwendig wäre.The laying of the bituminous membranes 2 but can also optionally done in such a way that the upper Bitumen waterproofing membrane 2 not with the one with a cover 5 provided edge strip 4 on the underlying Bitumen waterproofing membrane 2 is applied, but with the opposite edge, which continues to be self-adhesive is trained. It is thereby possible the upper bituminous sealing sheet 2 in the overlapping one Edge area directly by pressing cold self-adhesive with the first laid bituminous membrane 2 to connect, without the described heating of the Border area would be necessary.

Der mit einer Abdeckung 5 versehene Randstreifen 4 liegt bei dieser in Figur 3 dargestellten Verlegungsart im Abstand von der zuerst verlegten Bitumenabdichtungsbahn 2 unmittelbar auf der Unterlage 1 auf und verhindert in dem schmalen Randstreifen 4 eine Verklebung mit der Unterlage 1.The provided with a cover 5 edge strip. 4 lies with this type of installation shown in FIG at a distance from the first laid bitumen waterproofing membrane 2 directly on the pad 1 and prevented in the narrow edge strip 4 a bond with the pad 1.

Dies ist jedoch unerheblich, da die Abdichtung durch die Kaltselbstverklebung mit der nachfolgenden Bitumenabdichtungsbahn 2 vorgenommen wird, der nicht selbstklebende Randstreifen 4 verhindert lediglich, daß die Bitumenabdichtungsbahn 2 vollflächig mit der Unterlage 1 verklebt wird. Da der Randstreifen 4 gegenüber der Gesamtfläche der Bitumenabdichtungsbahn 2 jedoch nur eine Fläche in der Größenordnung von 2 - 5 % ausmacht, ist dies unerheblich, man erhält trotzdem eine vollständig ausreichende Festlegung der Bitumenabdichtungsbahn 2 auf der Unterlage 1.However, this is irrelevant, since the seal by the cold self-bonding with the subsequent bitumen waterproofing membrane 2 is made, which is not self-adhesive Edge strip 4 only prevents the Bitumen waterproofing membrane 2 over the entire surface with the base 1 is glued. Since the edge strip 4 opposite the Total area of the bituminous waterproofing membrane 2 but only an area of the order of 2 - 5%, this is irrelevant, you still get a complete adequate definition of the bitumen waterproofing membrane 2 on the pad 1.

Der Benutzer hat also bei Verwendung derselben Bitumenabdichtungsbahn 2 die Wahl, diese Bitumenabdichtungsbahn 2 entweder so zu verlegen, daß im überlappenden Randbereich eine Kaltselbstverklebung erfolgt oder daß im überlappenden Randbereich eine Verklebung erst durch eine Wärmebehandlung erfolgen kann. Es genügt dazu, die Verlegerichtung der Bitumenabdichtungsbahnen zu ändern, so daß auf die darunterliegende Bitumenabdichtungsbahn 2 entweder ein nicht mit einer Abdeckung versehener Randbereich der nächsten Bitumenabdichtungsbahn 2 aufgelegt wird oder ein mit einer Abdeckung 5 versehener Randbereich.The user therefore has when using the same bitumen waterproofing membrane 2 the choice, this bitumen waterproofing membrane 2 either so that in the overlapping Edge area is done a cold self-adhesive or that in the overlapping edge area gluing only through a heat treatment can take place. It is enough to do that Change the laying direction of the bitumen waterproofing membranes, so that on the underlying bitumen waterproofing membrane 2 either a not provided with a cover Edge area of the next bitumen waterproofing membrane 2 launched is or provided with a cover 5 Border area.

Claims (10)

  1.
