Abstract

A girder for supporting roof elements (5) along their edges consists of a profiled metal plate which forms an upwardly open, trough-shaped channel (1) having longitudinal edge strips (3), bent outwards on both sides, for connection of two series of elements. In order to prevent the blockage of the channel (1) by ice, the two side walls (2) of the groove (1) are connected to one another below their top edge by a cover plate (6), parallel to the bottom, which either passes over the full length of the groove and has passage openings (7) mutually spaced in the longitudinal direction of the channel or is composed of individual sections spaced apart from one another. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Träger zum randseitigen Abstützen von Dachelementen, bestehend aus einem Blechprofil, das eine nach oben offene, trogförmige Rinne mit beidseitigen, auswärtsgebogenen Längsrandstreifen zum Anschließen zweier Dachelementreihen bildet.The invention relates to a carrier for supporting roof elements on the edge, consisting of a sheet metal profile which forms an upwardly open, trough-shaped channel with bilateral, outwardly bent longitudinal edge strips for connecting two rows of roof elements.

Dachelemente, gleichgültig ob plattenförmig oder pro-0 filiert, werden randseitig auf Trägern abgestützt, die zum Abtragen der auftretenden Kräfte dienen. Das über die Dachelemente abfließende Regenwasser wird dabei in gesonderten Dachrinnen aufgefangen, was insbesondere dann zu Schwierigkeiten führt, wenn das Dach aus zwei oder mehreren Reihen von Dachelementen zusammengesetzt ist, weil in einem solchen Fall auch zwischen den aneinanderstoßenden Dachelementreihen Dachrinnen vorzusehen sind. Diese Dachrinnen schließen im allgemeinen an die beiden I-förmigen Träger der aneinanderstoßenden Dachelementreihen an und ragen in das Gebäudeinnere, so daß sich an der Unterseite der Dachrinnen Kondenswasser bilden kann, wenn die Unterseite nicht durch eine Isolierschicht abgedeckt wird. Außerdem besteht die Gefahr, daß die Dachrinnen durch Schnee und gefrierendes Wasser ausgefüllt werden, was zu einer Behinderung des Abflusses beispielsweise von Schmelzwasser führt, das sich ansammelt und über die Dachrinnen hinaus in das Dach eindringt.Roof elements, regardless of whether they are panel-shaped or pro-0 filleted, are supported on the edges on beams that serve to dissipate the forces that occur. The rainwater flowing out over the roof elements is collected in separate gutters, which leads to difficulties in particular when the roof is composed of two or more rows of roof elements, because in such a case gutters must also be provided between the rows of roof elements that abut one another. These gutters generally connect to the two I-shaped beams of the abutting rows of roof elements and protrude into the interior of the building, so that condensation can form on the underside of the gutters if the underside is not covered by an insulating layer. There is also a risk that the gutters are filled with snow and freezing water, which hinders the drainage of, for example, melt water that accumulates and penetrates into the roof through the gutters.

Um gesonderte Dachrinnen neben den Stützträgern für die Dachelemente zu vermeiden, ist es bereits bekanntgeworden (GB-PS 1 303 627), als Träger ein eine trogförmige Rinne bildendes Blechprofil einzusetzen, das zum Anschließen der Dachelemente auswärtsgebogene Längsrands treifen aufweist. Für zwei aneinanderstoßende Dachelementreihen ist auf Grund dieser Trägerausbildung nur mehr ein gemeinsamer Träger erforderlich, der zugleich als Dachrinne zwischen den beiden Dachelementreihen dient. Obwohl mit Hilfe dieser bekannten Trägerkonstruktion der Aufwand für die gesamte Dachkonstruktion herabgesetzt werden kann, bleibt auch bei solchen Trägern das Problem bestehen, wie mit einfachen Mitteln eine Schnee- und insbesondere eine Eisansammlung im Rinnteil des Trägers verhindert werden kann, um das Abfließen von Wasser stets sicherzustellen.To separate gutters next to the support beams for To avoid the roof elements, it has already become known (GB-PS 1 303 627) to use a sheet-metal profile forming a trough-shaped groove as a support, which has outwardly bent longitudinal edges for connecting the roof elements. For two abutting rows of roof elements, only one common beam is required due to this support design, which also serves as a gutter between the two rows of roof elements. Although with the help of this known support structure the effort for the entire roof structure can be reduced, the problem remains with such supports as well, how snow and in particular ice accumulation in the gutter part of the support can be prevented with simple means to keep the water from flowing away ensure.

Damit Dachrinnen nicht durch Festkörper, beispielsweise Blätter oder Schutt, verstopft werden können, ist es bereits bekannt (US-PS 2 271 081) diese Dachrinnen mit einem geneigten Schlitzblech zu überdachen, das einerseits ein eindringen des Wassers in die Dachrinnen und anderseits ein Abgleiten der Festkörper von der Traufe über die Dachrinnen hinweg ermöglichen soll. Mit Hilfe eines solchen Schlitzbleches läßt sich zwar das Verstopfen von Dachrinnen durch Festkörper und auch durch Schnee vermeiden, nicht aber eine Eisbildung innerhalb der Dachrinnen, was wiederum zu einer Verstopfung führen kann.So that gutters cannot be clogged by solid objects, such as leaves or debris, it is already known (US Pat. No. 2,271,081) to roof these gutters with an inclined slotted plate, which on the one hand penetrates the water into the gutters and on the other hand slides off Should allow solids from the eaves over the gutters. With the aid of such a slotted sheet, clogging of gutters by solid bodies and also by snow can be avoided, but not ice formation within the gutters, which in turn can lead to blockage.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Träger der eingangs geschilderten Art so zu verbessern, daß ein Eindringen von Wasser zwischen den Dachelementen und dem Träger auf Grund einer Verstopfung der Rinne insbesondere Eis wirksam vermieden werden kann.The invention is therefore based on the object of improving a support of the type described in such a way that penetration of water between the roof elements and the support due to blockage of the channel, in particular ice, can be effectively avoided.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die beiden Seitenwände der Rinne unterhalb ihres oberen Randes durch ein bodenparalleles Deckblech miteinander verbunden sind, das entweder über die Rinnenlänge durchgeht und Durchtrittsöffnungen in einem gegenseitigen Abstand in Rinnenlängsrichtung aufweist oder aus einzelnen mit Abstand voneinander angeordneten Abschnitten zusammengesetzt ist.The invention solves the problem in that the two side walls of the channel are connected below their upper edge by a cover plate parallel to the floor, which either over the channels passes through length and has passage openings at a mutual distance in the longitudinal direction of the channel or is composed of individual sections arranged at a distance from one another.

Das die Seitenwände der Rinne verbindende Deckblech verleiht dem Träger nicht nur eine größere Festigkeit, sondern schließt vor allem einen von der Rinne umgebenden Raum ab, der vom Gebäudeinneren her erwärmt werden kann, so daß der Träger zumindest im wesentlichen die Gebäudeinnentemperatur annehmen wird, was zunächst die Kondenswasserbildung auf der in das Gebäudeinnere ragenden Seite des Rinnenprofils verhindert. Daß sich auf der Unterseite des Deckbleches, das die Außentemperatur annehmen wird, Kondenswasser bilden kann, spielt keine Rolle, weil dieses Kondenswasser ja über die Rinne abfließen kann. Die vom Gebäudeinneren her erfolgende Erwärmung des durch das Deckblech abgedeckten Rinnenraumes verhindert außerdem, daß das durch die Durchtrittsöffnungen eindringende Wasser innerhalb der Rinne friert und dadurch die Rinne verstopft. Mit dem erfindungsgemäßen Träger kann somit die sichere Ableitung des anfallenden Regen- und Schmelzwassers gewährleistet werden.The cover plate connecting the side walls of the channel not only gives the support greater strength, but above all closes off a space which is surrounded by the channel and which can be heated from inside the building, so that the support will at least essentially assume the inside temperature of the building, which initially prevents the formation of condensation on the side of the channel profile protruding into the interior of the building. It does not matter that condensation can form on the underside of the cover plate, which will take on the outside temperature, because this condensation can flow off via the channel. The heating of the gutter space covered by the cover plate from the inside of the building also prevents the water penetrating through the passage openings from freezing inside the gutter and thereby clogging the gutter. With the carrier according to the invention, the safe discharge of the rain and melt water can thus be ensured.

Damit sich ein Wärmepolster innerhalb der Rinne ausbilden kann, dürfen die Druchtrittsöffnungen nicht zu eng nebeneinander angeordnet werden, sondern müssen in einem entsprechenden, in Rinnenlängsrichtung gemessenen Abstand voneinander liegen. Der Abstand darf aber selbstverständlich auch nicht zu groß sein, damit sichergestellt werden kann, daß das anfallende Wasser auch tatsächlich durch die Durchtrittsöffnungen in die Rinne gelangt. Da mit einer gewissen Wasserströmung auch auf dem Deckblech gerechnet werden muß, ist das Deckblech unterhalb des oberen Randes der Seitenwände der Rinne angeordnet, um einen Kanal zu bilden, der das Überfließen der Seitenwände der Rinne und damit das Eindringen des Wassers in das Dach ausschließt.So that a thermal cushion can form inside the channel, the through-openings must not be arranged too closely next to each other, but must be at a corresponding distance from each other, measured in the longitudinal direction of the channel. However, the distance must of course not be too large either, so that it can be ensured that the water actually gets through the through openings into the channel. Since a certain water flow must also be expected on the cover sheet, the cover sheet is arranged below the upper edge of the side walls of the channel to form a channel which prevents the overflow of the side walls of the channel and thus the penetration of water into the roof.

Die Durchtrittsöffnungen im Deckblech können durch geeignete Löcher gebildet werden. Es ist aber auch möglich, das Deckblech aus einzelnen mit Abstand voneinander angeordneten Abschnitten zusammenzusetzen, wobei das von den Dachelementen abfließende Wasser durch die Zwischenräume zwischen den einzelnen Deckblechabschnitten in die Rinne eindringt.The openings in the cover plate can through suitable holes are formed. However, it is also possible to assemble the cover plate from individual sections arranged at a distance from one another, the water flowing off the roof elements penetrating into the channel through the spaces between the individual cover plate sections.

Wie bereits ausgeführt wurdep ist der Abstand der Durchtrittsöffnungen voneinander von Bedeutung, damit innerhalb des durch das Deckblech abgedeckten Innenraumes ein Wärmepolster aufgebaut werden kann. Wie sich herausgestellt hat, werden diesbezüglich günstige Verhältnisse sichergestellt, wenn der gegenseitige Abstand der Durchtrittsöffnungen im Deckblech bzw. die Länge der einzelnen Deckblechabschnitte wenigstens der doppelten Rinnenbreite entspricht. Beträgt die Fläche der Durchtrittsöffnungen bzw. die freie Fläche zwischen den Deckblechabschnitten dabei höchstens ein Vierzigstel der Deckblechfläche einschließlich der Durchtrittsöffnungen bzw. der Durchtrittsflächen zwischen den einzelnen Deckblechabschnitten, so werden alle Bedingungen in vorteilhafter Weise erfüllt,As has already been stated, the distance between the through openings is important so that a thermal cushion can be built up within the interior covered by the cover plate. As has been found, favorable conditions are ensured in this regard if the mutual distance between the through openings in the cover plate or the length of the individual cover plate sections corresponds to at least twice the channel width. If the area of the passage openings or the free area between the cover sheet sections is at most a fortieth of the cover sheet area including the passage openings or the passage areas between the individual cover sheet sections, all conditions are advantageously met,

Sind schließlich zwischen den Seitenwänden der Rinne an das Deckblech anschließende, diese miteinander verbindende, an das Deckblech quer zur Rinnen anschließende Stegbleche vorgesehen, die mit Abstand oberhalb des Rinnenbodens enden, so wird nicht nur die Festigkeit des Trägers gegen ein Beulen erhöht, sondern auch zusätzlich eine Luftbewegung in Längsrichtung der Rinne unterbunden, wasselbstverständlich die Ausbildung von Wärmepolstern innerhalb der abgedeckten Rinne unterstützt. Diese Stegbleche dürfen aber den Abfluß des in die Rinne gelangenden Wassers nicht behindern. Sie müssen daher mit Abstand oberhalb des Rinnenbodens enden.Finally, are provided between the side walls of the channel to the cover plate, connecting them to each other, connecting to the cover plate transversely to the channels, which end at a distance above the channel bottom, not only increases the strength of the carrier against buckling, but also additionally prevents air movement in the longitudinal direction of the channel, which of course supports the formation of heat cushions within the covered channel. However, these web plates must not hinder the outflow of the water entering the channel. They must therefore end at a distance above the channel floor.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigen

  • Figur 1 einen erfindungsgemäßen Träger zum randseitigen abstützen von Dachelement in Querschnit, und
  • Figur 2 diesen Träger im Längsschnitt, jedoch in einem kleineren Maßstab.
The subject matter of the invention is shown in the drawing, for example. Show it
  • Figure 1 shows a carrier according to the edge support of roof element in cross-section, and
  • Figure 2 shows this carrier in longitudinal section, but on a smaller scale.

Wie insbesondere Fig. 1 zeigt, bildet der dargestellte Träger eine nach oben offene, trogförmige Rinne 1, an deren Seitenwände 2 auswärtsgebogene Längsrandstreifen 3 anschließen. Auf diesen Längsrandstreifen 3 sind über Anschlußstücke 4 Dachelemente 5 abgestützt, die an sich beliebig geformt sein können. Gemäß dem Ausführungsbeispiel bestehen die Dachelemente 5 aus rechteckigen Blechtafeln, die sowohl An Längsrichtung als auch in Querrichtung gewölbt sind, um vergleichsweise große Spannweiten bei geringen Blechstärken zu erzieler. Obwchl nach Fig. 1 die Dachelemente 5 nur auf einer Längsseite des Trägers ange- deutet sind, können selbstverständlich auf beiden Längsrandstreifen 3 Dachelementreihen befestigt werden.As shown in FIG. 1 in particular, the carrier shown forms an upwardly open, trough-shaped channel 1, on the side walls 2 of which are connected by outwardly curved longitudinal edge strips 3. On this longitudinal edge strip 3 4 roof elements 5 are supported via connectors, which can be arbitrarily shaped. According to the exemplary embodiment, the roof elements 5 consist of rectangular metal sheets which are curved both in the longitudinal direction and in the transverse direction in order to achieve comparatively large spans with low sheet thicknesses. 1, the roof elements 5 are only indicated on one longitudinal side of the carrier, 3 rows of roof elements can of course be attached to both longitudinal edge strips.

Die Seitenwände 2 der Rinne sind unterhalb ihres oberen Randes durch ein bedenparalleles Deckblech 6 erbunden, das mit der Rinne 1 ein Kastenprofil für den Träger bildet. Um das von den Dachelementen 5 abfließende Wasser in der Rinne 1 sammeln zu können, weist das über die Rinnenlänge durchlaufende Deckblech 6 Durchtrittsöffnungen 7 auf, die in Rinnenlängsrichtung mit einem Abstand voneinander angeordnet sind der wenigstens der doppelten Rennenbreite entspricht, Wegen dieses vergleichsweise großen Abstandes der Durchtrittsöffnungen voneinander kann sich innerhalb des durch das Deckblech 6 abgedeckten Innenraumes ein Wärmepolster ausbilden, und zwar durch die Erwärmung der Rinne 1 vom Rauminneren her. Dieser Wärmepolster bedingt eine entsprechende Temperatur des Trägers, so daß sich auf der in das Rauminnere ragenden Seite der Rinne kein Kondenswasser bilden kann. Die bei niedriger Außentemperatur zufolge des Wärmepolsters erwärmte Rinne 1 verhindert aber auch, daß Wasser an der Rinne anfriert und sie verlegt. Die sichere Wssserabfuhr ist folglich auch im winter gewährleistet.The side walls 2 of the channel are connected below their upper edge by a cover plate 6 parallel to the bed, which forms a box profile for the carrier with the channel 1. In order to be able to collect the water flowing away from the roof elements 5 in the channel 1, the cover plate 6 which runs over the channel length has through openings 7 which are arranged in the longitudinal direction of the channel at a distance from one another which corresponds to at least twice the width of the race, because of this comparatively large distance of Through openings of one another, a heat cushion can form within the interior covered by the cover plate 6, specifically by heating the channel 1 from the interior of the room. This heat cushion causes a corresponding temperature of the carrier, so that no condensation can form on the side of the channel that projects into the interior of the room. The gutter 1, which is heated at a low outside temperature due to the heat cushion, also prevents water from freezing to the gutter and laying it. The safe water drainage is therefore guaranteed even in winter.

Zur Aussteifung des Trägers können quer zur Rinne 1 verlaufende Stegbleche 8 zwischen den Seitenwänden 2 angeordnet werden, wobei diese an das Deckblech 6 anschließenden Stegbleche 8 mit Abstand vom Rinnenboden 9 enden müssen, um den Wasserfluß in der Rinne 1 nicht zu behindern. Neben ihrer die Festigkeit des Trägers betreffenden Aufgabe besitzen die Stegbleche 8 auch noch die Wirkung, den durch das Deckblech 6 abgedeckten Raum der Rinne in einzelne Kammern zu unterteilen, wodurch eine größere Luftströmung innerhalb der Rinne unterbunden wird, was wiederum die Ausbildung von Wärmepölstern fördert.To stiffen the girder, web plates 8 extending transversely to the channel 1 can be arranged between the side walls 2, these web plates 8 adjoining the cover plate 6 having to end at a distance from the channel bottom 9 so as not to impede the water flow in the channel 1. In addition to their task concerning the strength of the support, the web plates 8 also have the effect of dividing the space of the channel covered by the cover plate 6 into individual chambers, as a result of which a larger air flow within the channel is prevented, which in turn promotes the formation of heat pads.

Die Erfindung ist selbstverständlich nicht auf das dargestellte Ausführungsbeispiel beschränkt. So kann beispielsweise die im Querschnitt trapezförmige Rinnenform des Ausführungsbeispiels ohne weiteres durch ein U-Profil oder ein Muldenprofil ersetzt werden, wenn diese Profile den stsatischen Anforderungen entsprechen. Hinsichtlich der Wasserabführung und der Kondenswasserbildung kommt es nur auf die weitgehende Abdeckung der Rinne an, so daß die Rinne zumindest im abgedeckten Bereich nicht der Außentemperatur ausgesetzt ist.The invention is of course not limited to the illustrated embodiment. For example, the groove shape of the exemplary embodiment, which is trapezoidal in cross section, can easily be replaced by a U profile or a trough profile if these profiles meet the static requirements. With regard to water drainage and the formation of condensation, it is only a question of the extensive covering of the channel, so that the channel is not exposed to the outside temperature, at least in the covered area.
