Abstract

Bei einem Verfahren zur Herstellung eines Dachrandelements (11) aus Polystyrol, insbesondere EPS oder XPS, mit einer im Inneren des Dachrandelements (11) waagrecht verlaufenden Schiene (18) zum Anschluss weiterer Elemente an der Oberseite des Dachrandelements (11) ist erfindungsgemäß vorgesehen, dass man einen Heizdraht von der Seite einführt, sodass ein Schlitz (16) von der Seite bis zu der geplanten Position für die Schiene (18) entsteht, dass man dann mit dem Heizdraht den Raum für die Schiene ausschneidet und schließlich den Heizdraht durch denselben Schlitz (16) wieder aus dem Dachrandelement herausführt, wonach man den ausgeschnittenen Körper ausschiebt und die Schiene (18) einführt. Auf diese Weise bleibt die Oberseite des Dachrandelements unversehrt, nur auf der Seite gibt es durch den Schlitz (16) eine Möglichkeit, dass Feuchtigkeit eindringen kann. Um auch diese zu beseitigen, ist es zweckmäßig, dass man das Dachrandelement danach beschichtet, wodurch der Schlitz (16) geschlossen wird.In a method for producing a roof edge element (11) made of polystyrene, in particular EPS or XPS, with a rail (18) running horizontally inside the roof edge element (11) for connecting further elements to the upper side of the roof edge element (11), it is provided according to the invention Inserting a heating wire from the side, so that a slot (16) from the side to the planned position for the rail (18) is formed, that then cut with the heating wire, the space for the rail and finally the heating wire through the same slot ( 16) again leads out of the roof edge element, after which one pushes out the cut-out body and introduces the rail (18). In this way, the top of the roof edge element remains intact, only on the side there is a way through the slot (16) that moisture can penetrate.

Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Dachrandelements aus Polystyrol, insbesondere EPS oder XPS, mit einer waagrecht verlaufenden Schiene zum Anschluss weiterer Elemente an der Oberseite des Dachrandelements, wobei die Schiene im Inneren des Dachrandelements angeordnet ist.The present invention relates to a method for producing a roof edge element made of polystyrene, in particular EPS or XPS, with a horizontally extending rail for connecting further elements on the upper side of the roof edge element, wherein the rail is arranged in the interior of the roof edge element.

Stand der TechnikState of the art

Solch ein Dachrandelement ist z.B. in WO 2012/122576 A beschrieben. Im oberen Bereich ist eine als "Haltebalken" bezeichnete Schiene vorgesehen. Zu diesem Zweck wird auf der Oberseite ein nach oben offener Ausschnitt ausgeschnitten, in den der Haltebalken eingelegt wird. Der Ausschnitt wird dann mit einem Teil des herausgeschnittenen Materials verschlossen.Such a roof edge element is eg in WO 2012/122576 A described. In the upper part of a designated as "holding bar" rail is provided. For this purpose, an upwardly open cut-out is cut on the top, in which the retaining bar is inserted. The cutout is then closed with a portion of the cut out material.

Nachteilig bei dieser Lösung ist, dass zwei vertikale Schlitze verbleiben, die von einer etwa horizontalen Fläche ausgehen. Auf horizontalen Flächen kann sich jedoch sehr lange Feuchtigkeit halten, die dann in das Dachrandelement eindringt. Auch wenn das Dachrandelement nach dem Einlegen der Schiene beschichtet wird, so besteht doch die Gefahr, dass die Beschichtung im Laufe der Jahre Risse bekommt, durch die dann erst wieder Feuchtigkeit eindringen kann.A disadvantage of this solution is that two vertical slots remain, starting from an approximately horizontal surface. On horizontal surfaces, however, moisture can hold for a very long time, which then penetrates into the roof edge element. Even if the roof edge element is coated after inserting the rail, there is the danger that the coating cracks over the years through which then moisture can penetrate again.

Aus US 5842276 A und aus US 5943775 A (Letztere ist eine sogenannte "continuation in part" Ersterer) ist bekannt, Wandelemente aus Polystyrol zu fertigen, in die ausgehend von einer Seitenfläche Schlitze mit einem Heizdraht geschnitten werden, sodass danach in diese Schlitze Verstärkungselemente mit C-förmigem Querschnitt eingeschoben werden können. Infolge dieser Verstärkungselemente können die Wandelemente als tragende Elemente eingesetzt werden. Die Schlitze bzw. die Verstärkungselemente verlaufen senkrecht. Die Verstärkungselemente können aus der senkrechten Wandfläche vorstehen, damit weiterer Elemente angeschlossen werden können.Out US 5842276 A and from US 5943775 A (The latter is a so-called "continuation in part" former) is known to produce wall elements made of polystyrene, are cut in the starting from a side surface slits with a heating wire, so that thereafter can be inserted into these slots reinforcing elements with C-shaped cross-section. As a result of these reinforcing elements, the wall elements can be used as load-bearing elements. The slots or the reinforcing elements are perpendicular. The reinforcing elements can protrude from the vertical wall surface so that further elements can be connected.

In WO 2015/140715 ist ein ganz ähnliches Wandelement beschrieben. Hier wird aber zusätzlich zu dem Schlitz für das Verstärkungselement, das wiederum aus der Wandfläche vorsteht, auch ein im Querschnitt kreisrunder Kanal ausgeschnitten, der später mit Beton verfüllt wird.In WO 2015/140715 a very similar wall element is described. Here, however, in addition to the slot for the reinforcing element, which in turn protrudes from the wall surface, also a circular in cross-section channel cut, which is later filled with concrete.

Kurzbeschreibung der ErfindungBrief description of the invention

Es ist Aufgabe der vorliegenden Erfindung, den Nachteil des bekannten Dachrandelements zu beseitigen und ein Dachrandelement zu schaffen, das der Witterung länger standhält.It is an object of the present invention to eliminate the disadvantage of the known roof edge element and to provide a roof edge element that withstands the weather longer.

Diese Aufgabe wird durch ein Verfahren der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass man einen Heizdraht von der Seite einführt, sodass ein Schlitz von der Seite bis zu der geplanten Position für die Schiene entsteht, dass man dann mit dem Heizdraht den Raum für die Schiene ausschneidet und schließlich den Heizdraht durch denselben Schlitz wieder aus dem Dachrandelement herausführt, wonach man den ausgeschnittenen Körper ausschiebt und die Schiene einführt. Damit verbleibt nur ein einziger Schlitz, und der geht von einer senkrechten Fläche aus, wo Wasser relativ schnell abrinnt, sodass Feuchtigkeit nur wesentlich kürzer darauf verbleibt als auf einer waagrechten Fläche.This object is achieved by a method of the type mentioned in the present invention by introducing a heating wire from the side, so that a slot from the side to the planned position for the rail is created, that then with the heating wire the space for the rail cut out and finally leads out the heating wire through the same slot back from the roof edge element, after which pushes out the cut body and introduces the rail. This leaves only a single slot, and this starts from a vertical surface, where water runs off relatively quickly, so that moisture remains only much shorter than on a horizontal surface.

Es ist zweckmäßig, dass man das Dachrandelement danach beschichtet, wodurch der Schlitz geschlossen wird. Auf senkrechten Flächen besteht laut Norm nur die Notwendigkeit, dass die Beschichtung 25 Frost/Tau-Wechseln standhält, sodass man mit herkömmlichen Putzen auskommen kann. (Dies deshalb, weil Frost/Tau-Wechsel nur dann kritisch sind, wenn gleichzeitig Nässe dazukommt.) Wenn man für das Beschichten ein Wasser abweisendes und witterungsbeständiges Material verwendet, kann man diese Norm aber weitaus übertreffen. Man bekommt so auf einfache Weise ein Dachrandelement, das über Jahrzehnte der Witterung standhält.It is expedient that the roof edge element is then coated, whereby the slot is closed. On vertical surfaces, according to the standard, there is only a need for the coating to withstand 25 freeze / thaw cycles, so you can get by with conventional brushing. (This is because frost / dew changes are only critical when wet is added at the same time.) However, using a water-repellent and weather-resistant material for coating can far exceed this standard. You can easily get a roof edge element that withstands decades of weather.

Kurze Beschreibung der ZeichnungsfigurenShort description of the drawing figures

An Hand der beiliegenden Zeichnungen wird die vorliegende Erfindung näher erläutert. Es zeigt: Fig. 1 ein erfindungsgemäßes Dachrandelement von der Seite; Fig. 2 den Bereich links oben von Fig. 1 in vergrößertem Maßstab; Fig. 3 zeigt das Dachrandelement, bestimmungsgemäß verbaut; und Fig. 4 zeigt ein Detail von Fig. 3.With reference to the accompanying drawings, the present invention will be explained in more detail. It shows: Fig. 1 an inventive roof edge element from the side; Fig. 2 the area at the top left of Fig. 1 on an enlarged scale; Fig. 3 shows the roof edge element, installed as intended; and Fig. 4 shows a detail of Fig. 3 ,

Beschreibung der AusführungsartenDescription of the embodiments

Das Dachrandelement 11 weist oben zwei Schienen 18 auf, die zur Befestigung eines Attikablechs 21 (siehe Fig. 3) dienen. Diese Schienen 18 (siehe Fig. 1) haben von der Oberseite einen Abstand von 2 bis 5 cm. Die Breite der Schienen 18 beträgt mindestens 5 cm, damit sie sicher im Polystyrol halten. Die Schienen 18 können aus Holz, Aluminium oder Kunststoff (insbesondere PVC) bestehen.The roof edge element 11 has at the top two rails 18, which are used for fastening a Attikablechs 21 (see Fig. 3 ) serve. These rails 18 (see Fig. 1 ) have a distance of 2 to 5 cm from the top. The width of the rails 18 is at least 5 cm, so they safely hold in polystyrene. The rails 18 may be made of wood, aluminum or plastic (especially PVC).

Die Besonderheit besteht darin, dass die Oberfläche über den Schienen vollständig geschlossen ist.The special feature is that the surface over the rails is completely closed.

Dies wird dadurch erreicht (siehe Fig. 2), dass bei der Herstellung ein Heizdraht seitlich in das Dachrandelement 11 eingeführt wird, sodass ein Schlitz 16 geschmolzen wird. Dann wird der Heizdraht entlang einer rechteckigen Bahn 17 geführt, sodass der darin befindliche Quader vom restlichen Dachrandelement 11 getrennt wird. Schließlich wird der Heizdraht wieder entlang des Schlitzes 16 aus dem Dachrandelement 11 herausgeführt. Der entstandene Quader lässt sich einfach in Längsrichtung (also normal zur Zeichenebene) hinausschieben, sodass eine entsprechende Schiene 18 eingeschoben werden kann.This is achieved (see Fig. 2 ) that during manufacture a heating wire is inserted laterally into the roof edge element 11 so that a slot 16 is melted. Then, the heating wire is guided along a rectangular path 17, so that the cuboid therein is separated from the rest of the roof edge element 11. Finally, the heating wire is led out again along the slot 16 from the roof edge element 11. The resulting cuboid can simply be pushed out in the longitudinal direction (ie normal to the plane of the drawing) so that a corresponding rail 18 can be inserted.

Man erkennt unmittelbar, dass die Oberseite des Dachrandelements 11 völlig unversehrt bleibt, lediglich die vertikale Fläche ist durch einen einzigen Schlitz 16 unterbrochen. An diese Stelle gelangt aber nur wenig Feuchtigkeit, sodass es ausreichend ist, diese Fläche mit normalem Putz zu beschichten. Dies kann bereits bei der Herstellung des Dachrandelements 11 geschehen, sodass das Dachrandelement 11 auch schon vor dem Versetzen vor Feuchtigkeit geschützt ist. Bevorzugt wird das Dachrandelement 11 jedoch an beiden senkrechten Seiten und an der Oberseite mit einer speziellen Fassadenprofilbeschichtung versehen, die wesentlich wasserfester ist als herkömmlicher Putz.It can be seen immediately that the top of the roof edge element 11 remains completely intact, only the vertical surface is interrupted by a single slot 16. At this point, but only little moisture, so it is sufficient to coat this surface with normal plaster. This can already take place during the production of the roof edge element 11, so that the roof edge element 11 is also protected against moisture even before being displaced. Preferably, however, the roof edge element 11 is provided on both vertical sides and on the top with a special facade profile coating, which is much more waterproof than conventional plaster.

Fig. 3 zeigt das bestimmungsgemäß verbaute Dachrandelement 11. Auf einer Wand 22 ist eine Decke 23 aufgelegt. An der Wand 22 wird in üblicher Weise eine Fassadendämmung 29 angebracht. Auf der Decke 23 und dem oberen Ende der Fassadendämmung 29 wird ein Dachrandelement 11 aufgelegt und mittels einer Befestigungsschiene 25, die am Dachrandelement 11 verankert ist, so fixiert, dass es bündig mit der Fassadendämmung 29 abschließt. Nun legt man auf die Decke 23 eine Dampfsperre (nicht dargestellt) auf und zieht sie seitlich an dem Dachrandelement 11 ca. 10 cm hoch, damit eine Wanne gebildet wird. Auf die Dampfsperre legt man eine Gefälledämmung 24. Die Dicke der Gefälledämmung 24 nimmt in einer Richtung ab (in der Fig. 3 nicht erkennbar), sodass die Dachfläche leicht geneigt ist, obwohl die Decke 23 exakt waagrecht ist. Fig. 3 shows the intended purpose built roof edge element 11. On a wall 22, a ceiling 23 is placed. On the wall 22 a facade insulation 29 is attached in the usual way. On the ceiling 23 and the upper end of the facade insulation 29, a roof edge member 11 is placed and by means of a mounting rail 25, which is anchored to the roof edge element 11, fixed so that it is flush with the facade insulation 29. Now put on the ceiling 23 a vapor barrier (not shown) and pulls them laterally on the roof edge element 11 about 10 cm high, so that a tub is formed. On the vapor barrier you put a Gefälledämmung 24. The thickness of the Gefälledämmung 24 decreases in one direction (in the Fig. 3 not visible), so that the roof surface is slightly inclined, although the ceiling 23 is exactly horizontal.

In die Ecke zwischen Gefälledämmung 24 und Dachrandelement 11 wird ein Keil 26 gelegt, damit eine Dampfbremse 27 ohne Abstand auf die Gefälledämmung 24 gelegt und bis einschließlich zur oberen Flachseite des Dachrandelements 11 gelegt werden kann. Auf die Dampfbremse 27 kommt dann im Bereich der Gefälledämmung 24 eine Kiesschüttung (nicht dargestellt), z.B. 5 cm hoch.In the corner between Gefälledämmung 24 and roof edge member 11, a wedge 26 is placed so that a vapor barrier 27 can be placed without spacing on the slope insulation 24 and placed up to and including the upper flat side of the roof edge element 11. On the vapor barrier 27 then comes in the region of the Gefälledämmung 24 a gravel (not shown), e.g. 5 cm high.

Nun kommen die erfindungsgemäß eingesetzten Schienen 18 zum Einsatz (siehe Fig. 4): Man befestigt oberhalb der Schienen 18 an der Oberseite des Dachrandelements 11 Leisten 31 mit Schrauben 32, wodurch der Rand der Dampfbremse 27 (in Fig. 4 nicht dargestellt; siehe Fig. 3) verankert wird. Die Schrauben 32 durchdringen das über den Schienen 18 liegende Polystyrol und finden in den Schienen 18 ihren Halt.Now, the rails 18 used according to the invention are used (see Fig. 4 ): It attaches above the rails 18 at the top of the roof edge member 11 strips 31 with screws 32, whereby the edge of the vapor barrier 27 (in Fig. 4 not shown; please refer Fig. 3 ) is anchored. The screws 32 penetrate the polystyrene lying over the rails 18 and find their support in the rails 18.

Schließlich wird in üblicher Weise die Fassade hergestellt: man bringt auf der Fassadendämmung 29 und der Außenseite des Dachrandelements 11 ein Netz (eine Armierung) mit Spachtelmasse auf und darauf den Putz, insgesamt mit 30 bezeichnet.Finally, in the usual way, the facade is made: it brings on the facade insulation 29 and the outside of the roof edge element 11 a network (a reinforcement) with putty on it and the plaster, collectively designated 30.

Zuletzt befestigt man das Attikablech 21: Auf die Leisten 31 schraubt man mit Schrauben 34 ein Brett 33. Dieses dient als Auflage für einen so genannten Saumstreifen (Haftstreifen) 35, der mit Schrauben 36 befestigt wird. Auf diesen Saumstreifen 35 kann man dann das Attikablech 21 aufschieben, das zu diesem Zweck entsprechende Winkel 37 aufweist. Dadurch wird erreicht, dass das Attikablech 21 keinerlei Löcher für Schrauben hat, sodass dessen Wasserdichtigkeit mit Sicherheit gegeben ist. Das Brett 33 verhindert, dass sich der Saumstreifen 35 und das Attikablech 21 bei Belastung nach unten durchbiegen. Durch die Leisten 31, die nicht gleich dick sein müssen, kann die Neigung des Bretts 33 und somit des Saumstreifens 35 und des Attikablechs 21 verändert werden.Finally, the Attikablech 21 is fastened: a board 33 is screwed onto the strips 31 with screws 34. This serves as a support for a so-called hem strip (adhesive strip) 35, which is fastened with screws 36. On this hem strip 35 you can then postpone the Attikablech 21, which has corresponding angle 37 for this purpose. This ensures that the Attikablech 21 has no holes for screws, so that its waterproofness is given with certainty. The board 33 prevents the hem strip 35 and the Attikablech 21 bend under load down. Through the bars 31, which need not be the same thickness, the inclination of the board 33 and thus the seam strip 35 and the Attikablechs 21 can be changed.

Durch die vorliegende Erfindung ist das Dachrandelement 11 zuverlässig gegen eindringende Feuchtigkeit geschützt, auch bevor das Attikablech 21 angebracht wird. Bauunterbrechungen schaden daher in keiner Weise.By the present invention, the roof edge member 11 is reliably protected against moisture penetration, even before the Attikablech 21 is attached. Construction interruptions therefore do not harm in any way.

Mit dem erfindungsgemäßen Dachrandelement 11 wurden Auszugsversuche durchgeführt, d.h. es wurde versucht, eine angeschraubte Leiste 31 mit Gewalt vom Dachrandelement 11 zu entfernen. Dabei zeigte sich, dass die Leisten 18 sicher im Dachrandelement 11 verankert blieben, es wurden die Schrauben 32 aus den Leisten 18 gerissen. Der Schlitz 16 schwächt das Polystyrol also nicht so stark, dass die Leiste 18 herausgebrochen wird. Für den Versuch wurden etwa alle 50 cm Schrauben 32 gesetzt. Folgende Ergebnisse wurden erzielt (die Auszugskraft bezieht sich jeweils auf eine Schraube): Tabelle 1 Leiste Querschnitt [mm] Auszugskraft [N] Holzleiste 50x15 1837 Aluminiumleiste 50x3 1503 PVC-Leiste 60x3 1935 - - 369 With the roof edge element 11 according to the invention extraction tests were carried out, ie it was tried to remove a bolted bar 31 by force from the roof edge element 11. It was found that the strips 18 were securely anchored in the roof edge element 11, the screws 32 were torn from the strips 18. The slot 16 does not weaken the polystyrene so much that the bar 18 is broken. For the experiment about every 50 cm screws 32 were set. The following results were obtained (the pull-out force refers to one screw each): <b> Table 1 </ b> strip Cross section [mm] Pull-out force [N] wood strip 50x15 1837 aluminum bar 50x3 1503 PVC-strip 60x3 1935 - - 369

Die letzte Zeile wurde an einem Dachrandelement aus Polystyrol gemessen, das mit DKF 75 (eine von Austrotherm frei erhältliche Beschichtungsmasse) 6 mm dick beschichtet war und bei dem kein Loch geschnitten (und somit keine Leiste eingelegt) wurde. Man sieht, dass die Auszugskraft ohne Leiste zu gering ist und durch die Leiste stark erhöht wird. Man sieht auch, dass die Leiste selbst jedenfalls mit einer Kraft von mehr als 2-1935 N/m im Polystyrol gehalten ist, trotz des Schlitzes 16.The last line was measured on a roof edge element made of polystyrene coated with DKF 75 (a coating material available from Austrotherm) 6 mm thick and with no hole cut (and thus no strip inserted). It can be seen that the pull-out force without a bar is too low and is greatly increased by the bar. It can also be seen that the strip itself is held in polystyrene with a force of more than 2-1935 N / m, despite the slot 16.
