Definitions
- the invention relates to a bitumen or polymer bitumen welding track with scattering according to the preamble of claim 1.
- Such welding tracks are used in building construction and civil engineering to seal buildings against water, especially on flat roofs. Since they are provided with slate surface protection, they can be installed with the sealing package at the top and are particularly protected against the weather. The surface protection therefore enables a sophisticated layer structure without gravel fill. Slate chippings are particularly suitable as material for scattering, but other materials such as e.g. Sand, mica or the like can be used. This scattering adheres to the top of the welding path, which is therefore comparatively easy to produce by sprinkling and rolling the sprinkling material onto the still liquid cover layer. It is therefore permanently liable.
- a skin covering the building surface to be stored is produced in place from welding tracks according to the invention. This results in a limited length of the web, which must be delivered and processed as a roll and is therefore determined by the manageable weight. In general, about 30 kg / roll is added
- a sprinkling-free path edge of approx. 10 cm is provided on one longitudinal edge.
- the underside of the adjacent welding path adheres to the top of the edge.
- such a strip is formed by a factory-made separating film, the underside of which is connected to the top of the still soft covering compound before the welding path is sprinkled. During the laying process, this film is detached by means of a flame and the entire underside of the top sheet is glued to the adjacent welding sheet. Since this film is only removed by the heat of a welding flame, the edge strip remains free of scatter even when the web is scattered during the production process.
- the invention connects to known welding tracks of this type. These welding tracks are usually laid as a top layer, particularly when storing flat roofs.
- the first welding sheet which forms the roof skin, can be welded over the entire surface to the underside of the scattered welding sheet. This prevents, inter alia, that penetration of water through the non-adhesive edge of the scattered welding path of the top layer penetrates water, that is, it can penetrate into the stored structure.
- regular custody is expensive and labor-intensive.
- the safety of the edge bonds plays a decisive role, especially when it comes to the application with sprinkled top layer sheets, double-layer or straight-layer. That depends on the perfect base and the care with which the welding track was applied to the area to be kept. Inadequate welding and other errors during installation, but also unforeseen effects during the use of the building can lead to building damage due to water penetration.
- the invention has for its object to provide reliable storage with a welding track, which is easily converted for this purpose.
- the stray-free transverse strips of the adjoining new welding tracks enable head seams which are welded to the underside of the respective transverse strip-free transverse edge on the welding track adjoining in the longitudinal direction according to the invention. Since these cross connections with the longitudinal weld seam form an uninterrupted weld as a result of the uninterrupted adhesive surface and the weld tracks in the contiguous storage skin are therefore welded together on all four edges, undershot water cannot arise. Avoiding this only requires careful welding, which experience has shown can be guaranteed by flaming on the construction site.
- the invention has the advantage that it can be implemented with the means usual hitherto according to the production processes of the known type specified at the outset.
- the new welding tracks are therefore not much more complex than the known ones and can basically be processed as known.
- the safeguards produced from this can have two or more layers and can be provided in particular in the embodiment described at the beginning.
- the invention also enables single-layer storage without the risk of water forming under the surface, but with continuous surface protection due to the scattering of the bituminous welding tracks.
- These single-layer safeguards are relatively easier and less expensive.
- the scatter-free adhesive strips that run through the longitudinal and transverse seams do not require any changes to the organization of the construction site work, because the protruding parts of the web can easily be separated and attached to the first laid web.
- the invention is implemented with the features of claim 2, whereby the transverse welds of a given roof skin receive the same strength as the longitudinal welds, which among other things. is important because of the tensile forces.
- both strips as the transverse and the longitudinal edges of the new web, are realized with the foils which have been described at the beginning.
- the welding path (1) shown in FIG. 1 has an exemplary structure according to FIG. 2.
- its underside (3) consists of a thermoplastic elastomer bitumen (4) to which a glass fabric (5) is connected.
- a thermoplastic elastomer bitumen (6) in which a polyester fabric (7) is embedded.
- the top (8) consists of a scatter (10) on a layer (9) of elastomer bitumen.
- the spreading is usually formed by slate chippings.
- the web is of limited length for the reasons described at the beginning and accordingly has longitudinal edges (11, 12) and transverse edges (14, 15).
- a film (16) adheres to the layer (9) along one of the longitudinal edges (12). The film forms a streak-free strip (17).
- This adhesive edge adheres to the underside (3) as soon as the covering compound is plasticized with a flame.
- a stray-free strip (18) is provided along the transverse edge (15), on which the underside (3) of the welding track (1) adheres.
- This transverse stripe (18) forms with the longitudinal stripe a continuous, uninterrupted, scatter-free adhesive surface over the longitudinal edge (12) and the transverse edge (15).
- the free longitudinal strip (17) and the scatter-free transverse strip (18) are of the same width.
- the transverse strip (18) is formed by a film (19) which is detached when it is flamed.
- the film (19) is butted in front of the film (16).
- a flat roof (20) is shown in detail, which has a circumferential parapet (21).
- the storage of the rising inner parapet edge (22) and the top (23) of the parapet is not shown in detail.
- the top (24) of the flat roof (20) is kept with a continuous roof skin. This is in one layer and consists of the welded tracks (1) welded to one another according to FIGS. 1 and 2.
- the laying begins with the membrane (25), which ends with the transverse edge (14) with the parapet (21).
- the underside of the following welding path (26) is glued onto the strip (18), which is done by flaming an edge strip adjoining the transverse edge (14) onto the adhesive material. This is done in such a way that the longitudinal edges (11, 12) of the web (25) with the longitudinal edges (11, 12) the web (26) are aligned. As a result, a continuous, scatter-free strip is formed on the side formed by the transverse edge (12) from the partial length (17) of the adjoining webs (25, 26).
- the web (26) is therefore provided with a cutting edge (27).
- the cut end carries the stray-free transverse stripe (18) and the rest of the stray-free transverse stripe (17).
- the cut remainder (28) is aligned with its cutting edge (27) with the transverse edge (14) and forms the approach for a further welding path, not shown, which, like the welding path (26) with the welding path (25), is with the rest (28) can be connected.
- the result is a fully welded roof skin (29), only part of which is shown in Fig. 3, but in which the continuous adhesive surfaces (17, 18) exclude undershot water.
Abstract
Description
Die Erfindung betrifft eine Bitumen- oder Polymerbitumen-Schweißbahn mit Abstreuung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a bitumen or polymer bitumen welding track with scattering according to the preamble of
Derartige Schweißbahnen dienen im Hoch- und Tiefbau zur Abdichtung von Gebäuden gegen Wasser, insbesondere auf Flachdächern. Da sie mit dem Oberflächenschutz Schiefer versehen sind, können sie mit dem Dichtpaket oben verlegt werden und sind insbesondere gegen Witterungseinflüsse geschützt. Der Oberflächenschutz ermöglicht daher einen anspruchsvollen Schichtaufbau ohne Kiesschüttung. Als Material kommt für die Abstreuung insbesondere Schiefersplitt in Betracht, jedoch sind hierfür auch andere Materialien, wie z.B. Sand, Glimmer oder desgleichen verwendbar. Diese Abstreuung haftet auf der Oberseite der Schweißbahn, die sich deshalb vergleichsweise einfach produzieren läßt, indem auf die noch flüssige Deckschicht das Bestreumaterial aufgestreut und eingewalzt wird. Somit haftet es dauerhaft.Such welding tracks are used in building construction and civil engineering to seal buildings against water, especially on flat roofs. Since they are provided with slate surface protection, they can be installed with the sealing package at the top and are particularly protected against the weather. The surface protection therefore enables a sophisticated layer structure without gravel fill. Slate chippings are particularly suitable as material for scattering, but other materials such as e.g. Sand, mica or the like can be used. This scattering adheres to the top of the welding path, which is therefore comparatively easy to produce by sprinkling and rolling the sprinkling material onto the still liquid cover layer. It is therefore permanently liable.
Aus erfindungsgemäßen Schweißbahnen wird eine die zu verwahrende Gebäudefläche abdeckende Haut an Ort und Stelle hergestellt. Daraus ergibt sich eine begrenzte Länge der Bahn, die als Rolle angeliefert und verarbeitet werden muß und sich deshalb nach dem handhabbaren Gewicht bestimmt. Im allgemeinen geht man von ca. 30 kg/Rolle beiA skin covering the building surface to be stored is produced in place from welding tracks according to the invention. This results in a limited length of the web, which must be delivered and processed as a roll and is therefore determined by the manageable weight. In general, about 30 kg / roll is added
5 m Länge und 1 m Breite aus, was zu einer rechteckigen Schweißbahn führt, deren längere Dimension in der Regel bei ca. 5 m liegt. Da die Unterseite einer solchen Schweißbahn nicht sicher auf der Abstreuung haftet, ist an einer Längskante ein bestreufreier Bahnenrand von ca. 10 cm vorgesehen. Auf der Oberseite des Randes haftet die Unterseite der benachbarten Schweißbahn. Im allgemeinen wird ein solcher Streifen von einer fabrikmäßigen Trennfolie gebildet, deren Unterseite vor dem Abstreuen der Schweißbahn mit der Oberseite der noch weichen Deckmasse verbunden wird. Beim Verlegevorgang wird diese Folie mittels Flamme weggelöst und somit die Unterseite der Oberbahn mit der benachbarten Schweißbahn vollflächig verklebt. Da diese Folie nur durch die Hitze einer Schweißflamme abgelöst wird, bleibt der Randstreifen auch beim Abstreuen der Bahn während des Produktionsvorgangs abstreuungsfrei.5 m in length and 1 m in width, which leads to a rectangular welding track, the longer dimension of which is usually around 5 m. Since the underside of such a welding path does not adhere securely to the scatter, a sprinkling-free path edge of approx. 10 cm is provided on one longitudinal edge. The underside of the adjacent welding path adheres to the top of the edge. In general, such a strip is formed by a factory-made separating film, the underside of which is connected to the top of the still soft covering compound before the welding path is sprinkled. During the laying process, this film is detached by means of a flame and the entire underside of the top sheet is glued to the adjacent welding sheet. Since this film is only removed by the heat of a welding flame, the edge strip remains free of scatter even when the web is scattered during the production process.
Die Erfindung schließt sich an bekannte Schweißbahnen dieser Art an. Diese Schweißbahnen werden in aller Regel insbesondere bei der Verwahrung von Flachdächern als Oberlage verlegt. Die erste, die Dachhaut bildende Schweißbahn, ist vollflächig mit der Unterseite der abgestreuten Schweißbahn verschweißbar. Dadurch wird u.a. verhindert, daß durch die nicht mit Kleberand versehenen Querstöße der abgestreuten Schweißbahn der Oberlage eindringendes Wasser unterläufig wird, d.h. in das verwahrte Bauwerk eindringen kann. Allerdings ist die Regelverwahrung durch ihre Doppellagigkeit materialaufwendig und arbeitskostenintensiv.
Insbesondere bei der Ausführung mit bestreuten Oberlagenbahnen, doppellagig oder gerade einlagig, spielt die Sicherheit der Randverklebungen eine entscheidende Rolle. Das hängt von der einwandfreien Unterlage und von der Sorgfalt ab, mit der die Schweißbahn auf die zu verwahrende Fläche aufgebracht worden ist. Mangelhafte Verschweißungen und andere Fehler bei der Verlegung, aber auch unvorhergesehene Einwirkungen während der Nutzung des Gebäudes können zu Gebäudeschäden durch eindringen-des Wasser führen.The invention connects to known welding tracks of this type. These welding tracks are usually laid as a top layer, particularly when storing flat roofs. The first welding sheet, which forms the roof skin, can be welded over the entire surface to the underside of the scattered welding sheet. This prevents, inter alia, that penetration of water through the non-adhesive edge of the scattered welding path of the top layer penetrates water, that is, it can penetrate into the stored structure. However, due to its double layer, regular custody is expensive and labor-intensive.
The safety of the edge bonds plays a decisive role, especially when it comes to the application with sprinkled top layer sheets, double-layer or straight-layer. That depends on the perfect base and the care with which the welding track was applied to the area to be kept. Inadequate welding and other errors during installation, but also unforeseen effects during the use of the building can lead to building damage due to water penetration.
Der Erfindung liegt die Aufgabe zugrunde, eine zuverlässige Verwahrung mit einer Schweißbahn zu schaffen, die zu diesem Zweck auf einfache Weise umgestaltet ist.The invention has for its object to provide reliable storage with a welding track, which is easily converted for this purpose.
Diese Aufgabe löst die Erfindung mit den Merkmalen des Anspruches 1. Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche.The invention solves this problem with the features of
Gemäß der Erfindung werden durch die abstreuungsfreien Querstreifen der aneinander anschließenden neuen Schweißbahnen Kopfnähte ermöglicht, die mit der Unterseite der jeweils querstreifenfreien Querkante an der in Längsrichtung anschließenden Schweißbahn gemäß der Erfindung verschweißt sind. Da diese Querverbindungen mit der Längsschweißnaht infolge der ununterbrochenen Haftfläche eine demgemäß ununterbrochene Verschweißung bilden und die Schweißbahnen in der zusammenhängenden Verwahrungshaut mithin an allen vier Kanten miteinander verschweißt sind, kann unterläufiges Wasser nicht entstehen. Dessen Vermeidung setzt lediglich sorgfältige Verschweißungen voraus, was sich erfahrungsgemäß auf der Baustelle durch Aufflämmen gewährleisten läßt.According to the invention, the stray-free transverse strips of the adjoining new welding tracks enable head seams which are welded to the underside of the respective transverse strip-free transverse edge on the welding track adjoining in the longitudinal direction according to the invention. Since these cross connections with the longitudinal weld seam form an uninterrupted weld as a result of the uninterrupted adhesive surface and the weld tracks in the contiguous storage skin are therefore welded together on all four edges, undershot water cannot arise. Avoiding this only requires careful welding, which experience has shown can be guaranteed by flaming on the construction site.
Die Erfindung hat den Vorteil, daß sie sich mit den bislang üblichen Mitteln nach den Herstellungsverfahren der eingangs angegebenen bekannten Art verwirklichen läßt.The invention has the advantage that it can be implemented with the means usual hitherto according to the production processes of the known type specified at the outset.
Die neuen Schweißbahnen sind daher nicht wesentlich aufwendiger als die bekannten und lassen sich grundsätzlich wie bekannt verarbeiten. Die hieraus hergestellten Verwahrungen können zwei- oder mehrlagig sein und insbesondere in der eingangs beschriebenen Ausführung vorgesehen werden. Die Erfindung ermöglicht jedoch erstmalig auch einlagige Verwahrungen ohne die Gefahr der Bildung von unterläufigem Wasser, jedoch mit durchgehendem Oberflächenschutz durch die Aufstreuungen der bituminösen Schweißbahnen. Diese einlagigen Verwahrungen sind relativ einfacher und weniger kostspielig. Die über die Längs- und Quernähte durchgehenden abstreuungsfreien Klebstreifen setzen auch keine geänderte Organisation der Baustellenarbeiten voraus, weil sich die überstehenden Bahnteile einfach abtrennen und an die zuerst verlegte Bahn wieder ansetzen lassen.The new welding tracks are therefore not much more complex than the known ones and can basically be processed as known. The safeguards produced from this can have two or more layers and can be provided in particular in the embodiment described at the beginning. However, for the first time, the invention also enables single-layer storage without the risk of water forming under the surface, but with continuous surface protection due to the scattering of the bituminous welding tracks. These single-layer safeguards are relatively easier and less expensive. The scatter-free adhesive strips that run through the longitudinal and transverse seams do not require any changes to the organization of the construction site work, because the protruding parts of the web can easily be separated and attached to the first laid web.
Vorzugsweise wird die Erfindung mit den Merkmalen des Anspruches 2 verwirklicht, wodurch die Querschweißungen einer gegebenen Dachhaut die gleiche Festigkeit wie die Längsschweißungen erhalten, was u.a. wegen der Zugkräfte von Bedeutung ist.Preferably, the invention is implemented with the features of claim 2, whereby the transverse welds of a given roof skin receive the same strength as the longitudinal welds, which among other things. is important because of the tensile forces.
Gemäß einem weiteren, im Anspruch 3 gekennzeichneten Merkmal werden beide Streifen, als der Quer- und der Längsränder der neuen Bahn mit den Folien verwirklicht, die eingangs beschrieben worden sind.According to a further feature, characterized in
Hierdurch können auf der Baustelle die gleichen Mittel und Arbeitskräfte wie bisher für die Verschweißungen eingesetzt werden, ohne daß Umstellungen erforderlich werden.As a result, the same means and manpower as previously can be used for the welds on the construction site without the need for adjustments.

Die in Fig. 1 dargestellte Schweißbahn (1) hat einen beispielsweisen Aufbau nach Fig. 2. Hiernach besteht ihre Unterseite (3) aus einem thermoplastischen Elastomerbitumen (4), an das sich ein Glasgewebe (5) anschließt. Darauf folgt ein thermoplastisches Elastomerbitumen (6), in das ein Polyestergewebe (7) eingebettet ist. Die Oberseite (8) besteht aus einer Abstreuung (10) auf einer Schicht (9) aus Elastomerbitumen. Die Abstreuung wird in der Regel von Schiefersplitt gebildet.
Die Bahn ist aus den eingangs beschriebenen Gründen von begrenzter Länge und weist dementsprechend Längskanten (11, 12), sowie Querkanten (14, 15) auf. Längs einer der Längskanten (12) haftet auf der Schicht (9) eine Folie (16). Die Folie bildet einen abstreuungsfreien Streifen (17). Dieser Kleberand haftet auf der Unterseite (3), sobald die Deckmasse mit einer Flamme plastifiziert wird. Längs der Querkante (15) ist ein abstreuungsfreier Streifen (18) vorgesehen, auf dem die Unterseite (3) der Schweißbahn (1) haftet. Dieser Querstreifen (18) bildet mit dem Längsstreifen eine über die Längskante (12) und die Querkante (15) durchgehende, ununterbrochene, abstreuungsfreie Haftfläche.The welding path (1) shown in FIG. 1 has an exemplary structure according to FIG. 2. Hereafter, its underside (3) consists of a thermoplastic elastomer bitumen (4) to which a glass fabric (5) is connected. This is followed by a thermoplastic elastomer bitumen (6) in which a polyester fabric (7) is embedded. The top (8) consists of a scatter (10) on a layer (9) of elastomer bitumen. The spreading is usually formed by slate chippings.
The web is of limited length for the reasons described at the beginning and accordingly has longitudinal edges (11, 12) and transverse edges (14, 15). A film (16) adheres to the layer (9) along one of the longitudinal edges (12). The film forms a streak-free strip (17). This adhesive edge adheres to the underside (3) as soon as the covering compound is plasticized with a flame. A stray-free strip (18) is provided along the transverse edge (15), on which the underside (3) of the welding track (1) adheres. This transverse stripe (18) forms with the longitudinal stripe a continuous, uninterrupted, scatter-free adhesive surface over the longitudinal edge (12) and the transverse edge (15).
Wie sich aus der Darstellung der Fig. 1 ergibt, sind der freie Längsstreifen (17) und der abstreuungsfreie Quer-streifen (18) von gleicher Breite.As can be seen from the illustration in FIG. 1, the free longitudinal strip (17) and the scatter-free transverse strip (18) are of the same width.
Der Querstreifen (18) wird von einer Folie (19) gebildet, die beim Flämmen abgelöst wird. Um die durchgehende, ununterbrochene, abstreuungsfreie Haftfläche (17, 18) zu bilden, ist die Folie (19) stumpf vor die Folie (16) gestoßen.The transverse strip (18) is formed by a film (19) which is detached when it is flamed. In order to form the continuous, uninterrupted, scatter-free adhesive surface (17, 18), the film (19) is butted in front of the film (16).
In Fig. 3 ist ausschnittsweise ein Flachdach (20) dargestellt, welches eine umlaufende Attika (21) aufweist. Die Verwahrung der aufgehenden Attikainnenkante (22) und der Oberseite (23) der Attika ist im einzelnen nicht dargestellt. Die Oberseite (24) des Flachdaches (20) wird mit einer durchgehenden Dachhaut verwahrt. Diese ist einlagig und bestehht aus den miteinander verschweißten Schweißbahnen (1) gemäß den Fig. 1 und 2.In Fig. 3, a flat roof (20) is shown in detail, which has a circumferential parapet (21). The storage of the rising inner parapet edge (22) and the top (23) of the parapet is not shown in detail. The top (24) of the flat roof (20) is kept with a continuous roof skin. This is in one layer and consists of the welded tracks (1) welded to one another according to FIGS. 1 and 2.
Die Verlegung beginnt mit der Bahn (25), welche mit ihrer Querkante (14) mit der Attika (21) abschließt. Auf den Streifen (18) wird die Unterseite der folgenden Schweißbahn (26) aufgeklebt, was durch Aufflämmen eines an die Querkante (14) anschließenden Randstreifens auf das Klebematerial erfolgt. Das geschiet in der Weise, daß die Längskanten (11, 12) der Bahn (25) mit den Längskanten (11, 12) der Bahn (26) ausgefluchtet werden. Infolgedessen bildet sich an der von der Querkante (12) gebildeten Seite ein durchgehender, abstreuungsfreier Streifen aus den Teillänge (17) der aneinander anschließenden Bahnen (25, 26).The laying begins with the membrane (25), which ends with the transverse edge (14) with the parapet (21). The underside of the following welding path (26) is glued onto the strip (18), which is done by flaming an edge strip adjoining the transverse edge (14) onto the adhesive material. This is done in such a way that the longitudinal edges (11, 12) of the web (25) with the longitudinal edges (11, 12) the web (26) are aligned. As a result, a continuous, scatter-free strip is formed on the side formed by the transverse edge (12) from the partial length (17) of the adjoining webs (25, 26).
In der Darstellung ist angenommen, daß die Dachfläche mit weniger als zwei Bahnen in einer Richtung abgedeckt werden kann. Daher ist die Bahn (26) mit einer Schnittkante (27) versehen. Das abgeschnittene Ende trägt den abstreuungsfreien Querstreifen (18) und den Rest des abstreuungsfreien Querstreifens (17). Der abgeschnittene Rest (28) wird mit seiner Schnittkante (27) mit der Querkante (14) ausgefluchtet und bildet den Ansatz für eine weitere, nicht dargestellte Schweißbahn, die sich ebenso wie die Schweißbahn (26) mit der Schweißbahn (25) mit dem Rest (28) verbinden läßt. Im Ergebnis entsteht eine vollflächig abgeschweißte Dachhaut (29), von der in Fig. 3 nur ein Teil dargestellt ist, in der aber die durchgehenden Klebeflächen (17, 18) unterläufiges Wasser ausschließen.In the illustration it is assumed that the roof surface can be covered with less than two sheets in one direction. The web (26) is therefore provided with a cutting edge (27). The cut end carries the stray-free transverse stripe (18) and the rest of the stray-free transverse stripe (17). The cut remainder (28) is aligned with its cutting edge (27) with the transverse edge (14) and forms the approach for a further welding path, not shown, which, like the welding path (26) with the welding path (25), is with the rest (28) can be connected. The result is a fully welded roof skin (29), only part of which is shown in Fig. 3, but in which the continuous adhesive surfaces (17, 18) exclude undershot water.
