The gutters (1,1') are twisted into each other, by opening out the water fold (3), to be soldered together at the overlap. The roof gutter is of copper, zinc plate, galvanized steel plate, fine steel or aluminum.

Description

Die Erfindung betrifft einerseits eine Dachrinne gemäß den Merkmalen im Oberbegriff des Anspruchs 1 und andererseits ein Verfahren zur Herstellung solcher Dachrinnen.The invention relates on the one hand a gutter according to the features in the preamble of claim 1 and on the other hand, a method for producing such gutters.

Dachrinnen werden schußweise sich endseitig überlappend an der Unterkante (Traufe) eines Daches angebracht, um das von der Dachfläche abfließende Regenwasser aufzufangen und in ein Fallrohr abzuleiten. Dachrinne und Fallrohr werden unter anderem aus Kupfer, Zinkblech, verzinktem Stahlblech, Edelstahl oder Aluminium hergestellt. Dachrinnen aus Kupfer sind besonders hochwertig.Gutters become shotwise overlapping each other on the lower edge (eaves) a roof mounted to catch the runoff from the roof surface rainwater and divert into a downpipe. Gutter and downpipe will be among others made of copper, zinc sheet, galvanized sheet steel, stainless steel or aluminum. Gutters made of copper are particularly high quality.

Häufig wird eine Hängedachrinne mit halbkreisförmigem Querschnitt verwendet. Diese weist eine halbrunde Auffangschale (Rinnensohle) auf mit einem Wasserfalz an der einen Längsseite und einem eingedrehten Wulst an der anderen Längsseite. Maße und Werkstoffe von Hängedachrinnen sind in der deutschen Norm DIN 18 461 bzw. der europäischen Norm EN 612 festgelegt. Eine gattungsgemäße Dachrinne ist ebenfalls aus dem Dokument BE 75 53 81-A bekannt.Frequently, a suspended gutter with a semicircular cross-section is used. These has a semicircular drip tray (trough sole) with a Wasserfalz at the a longitudinal side and a screwed bead on the other longitudinal side. Dimensions and Hanging roof gutters are in the German standard DIN 18 461 or the European standard EN 612. A generic gutter is also from the document BE 75 53 81-A known.

Die einzelnen Dachrinnen sind üblicherweise 3 m lang und werden beim Verlegen schußweise aneinander gesetzt. Sie überlappen sich dann endseitig und werden im Überlappungsbereich untereinander wasserdicht verlötet. An der Dachunterkante wird die Dachrinne durch Rinnenhalter befestigt. The individual gutters are usually 3 m long and are laid when laying shot against each other. They then overlap each other and become in the Overlapping area soldered to each other waterproof. At the roof bottom is the gutter attached by gutter bracket.

Bei der Montage gestaltet sich das Ineinanderfügen der Enden der einzelnen Dachrinnen umständlich. Insbesondere die vorderen Wulste müssen vom Dachdecker unter Kraftaufwand regelrecht "ineinandergewürgt" werden. Hierbei besteht nicht nur die Gefahr, daß sich die Dachrinnen verbiegen und dann nicht mehr einwandfrei überlappend ineinanderliegen, sondern auch, daß sich der Monteur verletzt. In der Praxis behilft man sich dadurch, daß man die Wulste im Überlappungsbereich abschneidet und die Stöße stumpf aneinanderlötet. Dies ist jedoch mit zusätzlichem Aufwand verbunden und kann sowohl die Dichtheit als auch das äußere Erscheinungsbild der Naht nachteilig beeinflussen. Bei einer anderen Behelfsmaßnahme schneidet man mit einer Blechschere einen Zwickel aus dem Wulst. Damit verbindet sich jedoch der Nachteil, daß sich eine Wulst öffnen kann, so daß es zu einem Verwurf zwischen den aneinander gefügten Dachrinnen kommt.When assembling the nesting of the ends of the individual gutters designed laborious. In particular, the front beads must from the roofer under Force effort are literally "interlocked". This is not just the Danger that the gutters bend and then no longer perfectly overlapping nestled, but also that the mechanic injured. In practice This is done by cutting off the beads in the overlap area and the butt joints butt. However, this is associated with additional effort and can be both the tightness and the appearance of the seam adversely affect. With another makeshift measure one cuts with one Tin snips a gusset from the bead. However, this is associated with the disadvantage that a bead can open so that it is a throw between them Grooved gutters come.

Die US-PS 2,145,486 offenbart eine Dachrinne mit einem eingedrehten Wulst sowie einem Längsschenkel an einem Längsrand und mit einer 180°-Faltung am anderen Längsrand. An einem Ende ist der Wulst derart kurvenförmig beschnitten, dass er in einen kompletten Wulst einer zweiten Dachrinne mit rechtwinkling zur Längsachse verlaufender Stirnseite axial eingeschoben werden kann. Auch der Längsschenkel im Inneren des Wulstes fehlt in diesem Längenabschnitt.US-PS 2,145,486 discloses a gutter with a screwed bead as well one longitudinal leg at one longitudinal edge and with a 180 ° fold at the other Longitudinal edge. At one end, the bead is cut in such a curvilinear shape that it enters a complete bead of a second gutter with rechtwinkling to the longitudinal axis extending end face can be inserted axially. Also the longitudinal leg in Inside of the bead is missing in this length section.

Außerdem weist die Dachrinne im Bereich des beschnittenen Wulstes über den wesentlichen Umfangsbereich ihrer Auffangwanne eine S-förmige Faltung auf. Durch diese Faltung wird ein Aufnahmespalt geschaffen, in den das nicht beschnittene Ende einer Auffangwanne einer Dachrinne eingeschoben werden kann.In addition, the gutter in the area of the truncated bead on the essential peripheral area of their drip tray on an S-shaped fold. By this fold creates a receiving cleft into which the uncut End of a sump of a gutter can be inserted.

Die Herstellung der bekannten Dachrinne ist kompliziert, da nicht nur der Wulst beschnitten, sondern auch die S-förmige Faltung vor dem Runden der Auffangwanne gefertigt werden muss.The production of the known gutter is complicated because not only the bead trimmed, but also the S-shaped fold before rounding the drip tray must be made.

Der Erfindung liegt daher ausgehend vom Stand der Technik die Aufgabe zugrunde, eine Dachrinne zu schaffen, die eine einfachere Montage erlaubt. Weiterhin ist es Aufgabe der Erfindung, ein Verfahren zur Herstellung einer solchen Dachrinne aufzuzeigen.The invention is therefore based on the object of the prior art, the task To create a gutter, which allows easier installation. It is still the task of the invention to show a method for producing such a gutter.

Die Lösung des gegenständlichen Teils der Aufgabe besteht nach der Erfindung in den kennzeichnenden Merkmalen des Anspruchs 1.The solution of the objective part of the task according to the invention in the characterizing features of claim 1.

Kernpunkt der Erfindung bildet die Maßnahme, den nach innen gerichteten Längsschenkel des vorderen Wulstes einer Dachrinne von einer Stirnseite des Wulstes ausgehend gegenüber der Länge des Wulstes in Form einer Aussparung verkürzt auszubilden. Die Länge der Aussparung entspricht in etwa dem Überlappungsmaß zwischen zwei Dachrinnen. The core of the invention forms the measure, the inwardly directed longitudinal leg of the front bead of a gutter starting from a front side of the bead shortened form the length of the bead in the form of a recess. The length of the recess corresponds approximately to the overlap between two gutters.

Die Aussparung ermöglicht es, daß zwei Dachrinnen ohne großen Aufwand endseitig sich überlappend aneinander gesetzt werden können. Hierzu wird die anzusetzende Dachrinne mit ihrem Wulst auf die bereits montierte Dachrinne geschoben. Die Dachrinne ist dabei um ihre Längsachse nach vorne gedreht, so daß die Öffnung der Dachrinne nach vorne zum Monteur hin weist. Anschließend wird die angesetzte Dachrinne in die montierte Dachrinne gedreht. Dies ist möglich, da im Überlappungsbereich der Dachrinnen mindestens an einer Dachrinne der innen liegende Längsschenkel fehlt. Die Dachrinnen können so um die Längsachse des Wulstes ineinandergedreht werden, ohne daß die Drehbewegung durch die Längsschenkel behindert wird.The recess allows two gutters without much effort end can be placed overlapping each other. For this purpose, the Gutter with its bead pushed onto the already installed gutter. The gutter is rotated about its longitudinal axis to the front, so that the opening of the gutter facing forwards to the mechanic. Then the attached gutter turned into the mounted gutter. This is possible because in the overlapping area of the Gutters at least on a gutter of the inner longitudinal leg is missing. The gutters can thus be rotated around the longitudinal axis of the bead, without the rotational movement is hindered by the longitudinal legs.

Danach wird der Wasserfalz am dachseitigen Längsrand aufgezogen und die Dachrinnen ineinander gefügt.Thereafter, the Wasserfalz is raised at the roof-side longitudinal edge and the gutters intertwined.

Die beiden Dachrinnen liegen dann im Überlappungsbereich sauber und spannungsfrei aufeinander, so daß sie ohne Probleme verlötet werden können.The two gutters are then in the overlap area clean and stress-free on each other, so that they can be soldered without problems.

Die erfindungsgemäße Dachrinne ermöglicht mithin eine einfachere Montage. Dies erleichtert das Arbeiten wesentlich, da die Verlegung häufig über Kopf von einer Leiter oder einem Gerüst aus ausgeführt werden muß. Zusätzliche Schneidarbeiten an den Enden der Dachrinnen bei der Montage werden vermieden.The gutter invention thus allows easier installation. This facilitates working essential as the laying often overhead of a ladder or a scaffolding must be carried out. Additional cutting work on the Ends of the gutters during assembly are avoided.

Auch wenn es grundsätzlich möglich ist, den Längsschenkel einer erfindungsgemäßen Dachrinne an beiden Endseiten verkürzt auszubilden, wird es für die Praxis als zweckmäßig angesehen, eine Aussparung nur an einer Seite vorzusehen.Even if it is possible in principle, the longitudinal leg of an inventive Shortening gutter on both end sides, it is useful for the practice considered to provide a recess only on one side.

Die Lösung des verfahrensmäßigen Teils der Aufgabe besteht in den Merkmalen des Anspruchs 2. The solution of the procedural part of the task consists in the features of Claim 2.

Danach wird der Ausschnitt für die Verkürzung des Längsschenkels vor der Wulstherstellung eingebracht. Hierzu werden an einem Längsrand eines in Bandform bereitgestellten Ausgangsmaterials zunächst in einem der Länge einer Dachrinne entsprechenden Abstand seitliche Ausnehmungen erstellt und das Ausgangsmaterial im Bereich der Ausnehmungen rechtwinklig zu seiner Längserstreckung in Blechstreifen geteilt. Das Herstellen der Ausnehmungen und das Teilen in Blechstreifen kann gleichzeitig oder in nacheinander folgenden Arbeitsschritten erfolgen. Anschließend werden die Blechstreifen in bekannter Weise zu Dachrinnen endgeformt.Thereafter, the cutout for the shortening of the longitudinal leg before the bead production brought in. For this purpose, at a longitudinal edge of a band shape initially provided material corresponding in one of the length of a gutter Distance created lateral recesses and the starting material in the Area of the recesses perpendicular to its longitudinal extent in metal strips divided. Making the recesses and dividing into metal strips can be done simultaneously or in successive steps. Then be the sheet metal strips in a known manner to gutters molded.

Eine zweckmäßige Vorgehensweise bei der Endformung besteht darin, zunächst den Wasserfalz zu knicken und den Wulst einzudrehen. Anschließend wird der Blechstreifen in einem Rollenformsatz biegewalztechnisch zur halbrunden Dachrinne geformt.An expedient procedure in the final shaping is, first the Buckle water fold and screw in the bead. Subsequently, the sheet metal strip formed in a roll form set bending roll technology to semicircular gutter.

Das erfindungsgemäße Verfahren ermöglicht eine rationelle und einfache Herstellung von Dachrinnen mit einem an einer Endseite verkürzten Längsschenkel.The inventive method allows a rational and simple production gutters with a longitudinal leg shortened at one end side.

Die Figur 1 zeigt einen Querschnitt einer halbrunden Dachrinne 1 gemäß DIN 18 461. Die Dachrinne 1 weist eine Auffangschale 2 auf mit einem angeformten Wasserfalz 3 am dachseitigen Längsrand 4 und einem eingedrehten Wulst 5 am äußeren Längsrand 6.1 shows a cross section of a semicircular gutter 1 according to DIN 18 461. The gutter 1 has a drip tray 2 on with a molded Wasserfalz 3 at the roof-side longitudinal edge 4 and a screwed bead 5 at the outer longitudinal edge. 6

Der Wulst 5 ist in seiner Konfiguration annähernd hohlzylindrisch. Mit einem gegenüber dem Radius R1 des Wulstes 5 kleineren Radius R2 schließt sich ein etwa zur Längsachse LA des Wulstes 5 gerichteter, im wesentlichen ebener Längsschenkel 7 an. Zwischen dem Übergang 8 von dem Wulst 5 auf den Längsschenkel 7 und der benachbarten Außenseite 9 der Auffangschale 2 ist ein Spalt 10 ausgebildet.The bead 5 is approximately hollow cylindrical in configuration. With a relation to the radius R 1 of the bead 5 smaller radius R 2 is followed by a directed approximately to the longitudinal axis LA of the bead 5, substantially flat longitudinal leg 7 at. Between the transition 8 of the bead 5 on the longitudinal leg 7 and the adjacent outer side 9 of the drip tray 2, a gap 10 is formed.

Wie anhand der Figuren 2 und 3 deutlich wird, ist der Längsschenkel 7 einer Dachrinne 1', 1" durch eine Aussparung 11 gegenüber der Länge LW des Wulstes 5 von einer Stirnseite 12 ausgehend verkürzt ausgebildet.As is clear from FIGS. 2 and 3, the longitudinal leg 7 of a gutter 1 ', 1 "is shortened from a front side 12 by a recess 11 opposite the length L W of the bead 5.

Die Länge L11 der Aussparung 11 entspricht in etwa dem Überlappungsmaß Ü zwischen den Dachrinnen 1', 1". Der Wulst 5 erstreckt sich über die gesamte Länge LD einer Dachrinne 1', 1". Durch die Aussparung 11 kann die Dachrinne 1" bei der Montage endseitig mit ihrem Wulst 5 auf die Dachrinne 1' gesteckt werden. Danach werden die Dachrinnen 1', 1" spannungsfrei ineinander gedreht, ohne daß sich die Längsschenkel 7 von Dachrinne 1' und 1" hierbei behindern können. The length L 11 of the recess 11 corresponds approximately to the overlap dimension Ü between the gutters 1 ', 1 ". The bead 5 extends over the entire length L D of a gutter 1', 1". Through the recess 11, the gutter 1 "can be put on the gutter 1 'at the end with its bead 5. Thereafter, the gutters 1', 1" are rotated without tension into each other without the longitudinal legs 7 of the gutter 1 'and 1 "can hinder this.

Anschließend werden die Dachrinnen 1', 1" durch Aufziehen des Wasserfalzes 3 am Längsrand 4 ineinander gefügt und im Überlappungsbereich 13 verlötet.Then the gutters 1 ', 1 "by mounting the Wasserfalzes 3 am Longitudinal edge 4 joined together and soldered in the overlapping area 13.

In der Figur 4 ist ein Ausschnitt aus einem bandförmigen Ausgangsmaterial 14 dargestellt, von dem Blechstreifen 15 abgeteilt werden, die zur Herstellung von Dachrinnen dienen, deren Längsschenkel an beiden Endseiten durch Aussparungen verkürzt sind.FIG. 4 shows a detail of a ribbon-shaped starting material 14, are separated from the metal strip 15, which is used to produce gutters serve, the longitudinal limbs are shortened at both end sides by recesses.

Hierzu werden an einem Längsrand 16 in einem der Länge LD einer Dachrinne entsprechenden Abstand seitliche Ausnehmungen 17 erstellt. In dem hier erläuterten Fertigungsbeispiel ist die Ausnehmung 17 doppelt so lang wie eine spätere Aussparung im Längsschenkel einer Dachrinne. Durch Teilen des Ausgangsmaterials 14 rechtwinklig zu seiner Längserstreckung in der Mitte der Ausnehmungen 17 erhält man Blechstreifen 15 mit seitlichen Ausnehmungen 17', 17" an beiden Enden.For this purpose, at a longitudinal edge 16 in a length L D of a gutter corresponding distance lateral recesses 17 are created. In the manufacturing example explained here, the recess 17 is twice as long as a later recess in the longitudinal leg of a gutter. By dividing the starting material 14 at right angles to its longitudinal extent in the middle of the recesses 17 is obtained sheet metal strip 15 with lateral recesses 17 ', 17 "at both ends.

Die Herstellung der Ausnehmungen 17 und das Teilen in Blechstreifen 15 kann gleichzeitig oder in nacheinander folgenden Arbeitsschritten erfolgen.The preparation of the recesses 17 and the parts in metal strip 15 can simultaneously or in successive steps.

Einen Blechstreifen 18, der nur an einem Ende 19 eine Ausnehmung 20 besitzt, zeigt Figur 5. Die Ausnehmung 20 ist am Längsrand 21 gleichzeitig mit dem Abteilen des Blechstreifens 18 von einem in Bandform bereitgestellten Ausgangsmaterial erstellt worden. Die Tiefe der Ausnehmung H20 entspricht der Höhe eines an dem Wulst einer Dachrinne ausgebildeten Längsschenkels.FIG. 5 shows a metal strip 18 which has a recess 20 only at one end 19. The recess 20 has been created at the longitudinal edge 21 simultaneously with the division of the metal strip 18 from a starting material provided in strip form. The depth of the recess H 20 corresponds to the height of a formed on the bead of a gutter longitudinal leg.

Bei der Endformung (siehe Figuren 6 bis 8) eines Blechstreifens 22 wird zunächst der Wasserfalz 23 geknickt und der Wulst 24 eingedreht. Der Längsschenkel 25 des Wulstes 24 ist entsprechend den vorstehenden Erläuterungen endseitig verkürzt ausgebildet. Anschließend wird der so vorbereitete Blechstreifen 22 in einem Rollenformsatz 26 durch Biegewalzen zur halbrunden Dachrinne 27 geformt. In the final shaping (see Figures 6 to 8) of a metal strip 22 is first the Wasserfalz 23 kinked and the bead 24 screwed. The longitudinal leg 25 of the bead 24 is formed according to the above explanations shortened end. Subsequently, the thus prepared sheet metal strip 22 in a roll molding set 26th formed by bending rolls to semicircular gutter 27.

    c) the gap (10) has a width such that during assembly, a roof gutter (1") to be attached can be placed with its bead (5, 24) on an already assembled roof gutter (1') so as to overlap one another on the end face and the roof gutter (1") to be attached can then be rotated about the longitudinal axis (LA) of the bead (5, 24) into the assembled roof gutter (1').
  2. Method for producing roof gutters according to claim 1, characterised in that lateral recesses (17, 20) are produced initially on one longitudinal edge (16, 21) of a starting material (14) provided in strip form at a spacing (LD) corresponding to the length of a roof gutter (1, 1', 1", 27) and in the region of the recesses (17, 20) the starting material (14) is divided into sheet metal strips (5, 18, 22) at right angles to its longitudinal extension, whereupon the water fold (3, 23) is formed by bending on one sheet metal strip (15, 18, 22) and the bead (5, 24) is turned in and in that the sheet metal strip (15, 18, 22) thus prepared is then formed in a roller forming assembly (26) by roll bending to form the semicircular roof gutter (1, 1', 1", 27).
