Description

Die Erfindung betrifft ein Firstabdichtungs- und -belüftungselement, das unter Firststeinen oder gegebenenenfalls anderen Firstabdeckungsteilen auf einer Firstbohle anzubringen ist und nach Auflage eine Wölbungsfläche beschreibt und das herausgehobene Auflager für die Innenflächen der Firststeine besitzt, unterhalb seiner äußeren Randbereiche mit eindrückbaren Randstreifen unterfüttert ist und über seine Wölbungsfläche verteilte Luftdurchtrittsöffnungen besitzt, die in Bereichen außerhalb der Auflager angeordnet sind.The invention relates to a ridge sealing and ventilation element, which is to be attached under ridge stones or possibly other ridge cover parts on a ridge screed and, after being placed on it, describes a curvature surface and has the raised support for the inner surfaces of the ridge stones, is lined with push-in edge strips below its outer edge regions and above its curved surface has distributed air passage openings which are arranged in areas outside the supports.

Ein solches Firstabdichtungs- und -belüftungselement ist aus der deutschen Offenlegungsschrift 3 533 822 bekannt. Dieses Element, das nach Auflage eine Wölbungsfläche beschreibt, wird über die ganze Länge direkt auf die Firstbohle genagelt. Auf der nach außen zeigenden Fläche sind vereinzelte, kreisrunde Auflager und spiegelbildlich zu beiden Seiten der Firstbohle liegende runde Lüftungsöffnungen vorgesehen, wobei die Lüftungsöffnungen mit einer Wulst umgeben sind. Unterhalb ist die Wölbungsflache an den äußersten Randbereichen mit eindrückbaren Randstreifen unterfüttert. Üblicherweise werden die vorgenannten Firstabdichtungs- und -belüftungselemente zwischen einem Firststein aus Beton oder Firstziegel aus gebranntem Ton und der Firstbohle angebracht, um das Gewicht der aufgereihten Firststeine aufzunehmen und eine Belüftung unterhalb der Firststeine im Firstbereich zu gewährleisten.Such a ridge sealing and ventilation element is known from German Offenlegungsschrift 3 533 822. This element, which describes a vaulted surface after laying, is nailed directly onto the ridge plank over the entire length. On the outward-facing surface there are individual, circular supports and mirrored round ventilation openings on both sides of the ridge screed, the ventilation openings being surrounded by a bead. Below, the arched area is lined with push-in edge strips at the outermost edge areas. Usually, the above-mentioned ridge sealing and ventilation elements are attached between a ridge stone made of concrete or ridge tile made of fired clay and the ridge screed in order to absorb the weight of the ridge stones lined up and to ensure ventilation below the ridge stones in the ridge area.

Eine Verbesserung der Firstabdichtungs- und -belüftungselemente ist darauf gerichtet, den Materialverbrauch für die Aufstellung derartiger Elemente zu verringern, d.h. ein relativ dünnes Material zu verwenden, wobei die Belüftungseigenschaften des Elementes gegenüber dem bekannten Element zumindest gleichrangig, möglichst jedoch noch verbessert sein soll.An improvement of the ridge sealing and ventilation elements is aimed at reducing the material consumption for the installation of such elements, i.e. to use a relatively thin material, the ventilation properties of the element compared to the known element should be at least equal, but if possible should be improved.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Auflager als vereinzelt angeordnete, mit ihren Seitenflächen quer zur Fahrtrichtung stehende Flossen gestaltet sind, die in Abstand von der Firstlinie beginnen, entlang den Elementseitenkanten angeordnet sind und über die Elementseitenkanten nach außen überstehen.According to the invention the object is achieved in that the supports are designed as individually arranged fins with their side surfaces transverse to the direction of travel, which start at a distance from the ridge line, are arranged along the element side edges and protrude beyond the element side edges.

Hierdurch ergeben sich zahlreiche Lüftungswege. Insbesondere sind quer zur Firstrichtung verlaufende Lüftungswege in ausreichendem Maß und mit verhältnismäßig großem Querschnitt verwirklicht. Es ist jedoch auch längs der Firstrichtung ein Belüftungsstrom ermöglicht.This results in numerous ventilation routes. In particular, ventilation paths running transversely to the ridge direction are realized to a sufficient extent and with a relatively large cross-section. However, a ventilation flow is also possible along the ridge direction.

Die Elemente werden bevorzugt aus Kunststoff hergestellt, beispielsweise Polyvinylchlorid oder Polyethylen. Es sei jedoch nicht ausgeschlossen, Elemente auch aus Blech zu formen. Insbesondere bei einer Herstellung aus Kunststoff lassen sich die Flossen aus Vollmaterial oder aber auch als ausgestülpte Hohlkörper gestalten, und zwar vorzugsweise einstückig mit dem übrigen Material des Elementes. Dabei sei ausdrücklich auch auf die Möglichkeit verwiesen, daß das Firstabdichtungs- und -belüftungslement unmittelbar nach der Herstellung zunächst plan liegt und erst unter der Last der Firststeine eine Wölbungsfläche ausbildet. Um die dafür erforderliche Wölbfähigkeit zu verbessern, stehen vorzugsweise die Flossen in Abstand von der Firstlinie und sind dazu noch etwas schräg geschnitten, wobei sich zwei Knickbereiche ergeben, die zwischen Flossen und Firstlinie verlaufen.The elements are preferably made of plastic, for example polyvinyl chloride or polyethylene. However, it is not out of the question to also form elements from sheet metal. In particular in the case of production from plastic, the fins can be made from solid material or else as an inverted hollow body, preferably in one piece with the remaining material of the element. We expressly refer to the possibility that the ridge sealing and ventilation element lies flat immediately after manufacture and only forms a vaulted surface under the load of the ridge stones. In order to improve the required arching ability, the fins are preferably at a distance from the ridge line and are also cut somewhat obliquely, with two There are buckling areas that run between the fins and the ridge line.

Die Anordnung der Flossen geschieht im allgemeinen in Reihen, wobei wenigstens ein Teil der Flossen auch in kammartigen Reihen angeordnet sein kann, die sich über die Wölbung des Elementes erstrecken. Hierbei wird die Auflagelast des Firststeines besonders gut über die Fläche verteilt. Dabei ist auch möglich, Reihen von derartigen Flossen auf über die Wölbung der Elemente verlaufenden Sicken anzuordnen, so daß eine besonders tragfähige Anordnung gegeben ist.The fins are generally arranged in rows, at least some of the fins also being able to be arranged in comb-like rows which extend over the curvature of the element. Here the bearing load of the ridge stone is distributed particularly well over the surface. It is also possible to arrange rows of such fins on beads running over the curvature of the elements, so that a particularly stable arrangement is given.

Eine weitere Ausgestaltung liegt darin, wenigstens eine der Seitenkanten des Elementes treppenartig abzustufen, wobei die Stufen sich in Firstrichtung erstrecken. Diese Gestaltung hat den Vorteil, daß entlang der Stufenkanten jeweils nachträglich oder während des Herstellens mit Hilfe von Schneidwerkzeugen ein Streifen nach dem anderen entsprechend jeweils einer Stufe abgeschnitten werden kann, so daß aus breiten schmalere Elemente hergestellt werden können, die damit für die entsprechenden Firststeine in einfacher Weise angepaßt sind. Zur Herstellung ist demnach nur noch ein Werkzeug erforderlich; die Lagerhaltung ist auch wesentlich verbilligt, wenn jeweils nur eine breite Form vorgegeben ist.A further embodiment is to step down at least one of the side edges of the element in a step-like manner, the steps extending in the ridge direction. This design has the advantage that along the step edges each later or during manufacture with the help of cutting tools, one strip after the other can be cut off one step at a time, so that wider, narrower elements can be produced, which are therefore suitable for the corresponding ridge stones are easily adapted. Accordingly, only one tool is required for production; warehousing is also significantly cheaper if only a broad form is specified.

Die Lüftungsschlitze sind als Einschnitte gestaltet, die bekanntermaßen spiegelbildlich zu beiden Seiten der Firstlinie liegen, und so eine gute Luftdurchspülung des unmittelbaren Firstbereiches zu ermöglichen.The ventilation slots are designed as incisions, which are known to be mirror images on both sides of the ridge line, thus allowing good air purging in the immediate ridge area.

Üblicherweise haben die Lüftungsöffnungen eine längliche Rechteckform, wobei die Langseite entlang des Firstes liegt. Die Lüftungsöffnungen sind in bekannter Weise umgeben von einem Randsteg oder von einer Rundwulst, so daß Kondenswasser oder eingedrücktes Regenwasser nicht in die Lüftungsöffnung fließen kann. Diese Randstreifen können auch noch so gestaltet sein, daß sie nach oben hin eine schiffbugartige Form besitzen, an der das Wasser sich nicht stauen kann. Die Lüftungsöffnungen können auch in voneinander abgesetzten, entlang der Firststeine aufgereihten Hohlsockeln angeordnet sein.The ventilation openings usually have an elongated rectangular shape, with the long side lying along the ridge. The ventilation openings are surrounded in a known manner by an edge web or by a round bead, so that condensed water or indented rainwater is not can flow into the ventilation opening. These edge strips can also be designed so that they have a bow-like shape at the top, at which the water can not build up. The ventilation openings can also be arranged in hollow bases which are set apart from one another and lined up along the ridge blocks.

Darüberhinaus ist möglich, unterhalb der Lüftungsöffnungen kleine, kastenartige Flugschneesammler anzuordnen, wie sie aus einer anderen Anmeldung des Anmelders bekannt sind; alternativ dazu ist es auch möglich, die Lüftungsöffnungen zur Firstseite hin von einem nach unten überragenden Rand zu umgeben, wobei vorzugsweise der untere Rand zusammen mit einem Boden eine Wanne bildet, die wiederum in ihrem Boden und/oder Rändern Belüftungsperforationen aufweist.Furthermore, it is possible to arrange small, box-like flying snow collectors below the ventilation openings, as are known from another application by the applicant; alternatively, it is also possible to surround the ventilation openings towards the ridge side by a rim projecting downwards, the lower rim preferably forming a trough together with a bottom, which in turn has ventilation perforations in its bottom and / or edges.

In der Figur 1 ist ein Firstabdichtungs- und belüftungselement in einer ersten Ausführungsform, Bezugszahl 100, dargestellt. Das Element wird unter einer Reihe von Firststeinen üblicher Form angeordnet. Gegebenenfalls können auch noch andere Firstabdeckungsteile zwischen dem Firststein und dem Element 100 angebracht sein, die jedoch im wesentlichen an der Aufgabe und Funktion der nachfolgend zu beschreibenden Elemente 100 oder 200 bzw. 300 nichts ändern. Anstelle von Firststeinen können auch Firstziegel aus gebranntem Ton in verschiedener Breite und Wölbung eingesetzt werden. Es sei auch nicht ausgeschlossen, das Element zur Grateindeckung zu verwenden.1 shows a ridge sealing and ventilation element in a first embodiment, reference number 100. The element is arranged under a series of ridge stones of the usual shape. If necessary, other ridge cover parts can also be attached between the ridge stone and the element 100, which however, essentially do not change the task and function of the elements 100 or 200 or 300 to be described below. Instead of ridge bricks, fired clay ridge bricks in various widths and curvatures can also be used. It is also not excluded to use the element to cover the ridges.

Das Firstabdichtungs- und -belüftungselement 100 ist aus einer eingefärbten, 1 - 3 mm dicken Kunststoffolie, beispielsweise Polyvinylchlorid, oder aus einem entsprechenden, gespritzten Kunststoffmaterial, z. B. Polyethylen, hergestellt. Es ist modulartig aufgebaut, wobei die Modullänge M beträgt und im vorliegenden Fall jeweils eine über einen Teil der Wölbung verlaufende Sicke 7, 8 umfaßt. Ein einzelnes Element 100 kann zwei, vier oder mehr derartiger Modulen umfassen. Beim Verlegen wird das Element 100 überlappend angeordnet. Es wird hierzu jeweils auf die vorhandene Firstbohle aufgenagelt. Die Firststeine werden dann mit Firstklammern befestigt, wie dies bei der üblichen Firstverlegetechnik bekannt ist.The ridge sealing and ventilation element 100 is made from a colored, 1-3 mm thick plastic film, for example polyvinyl chloride, or from a corresponding, injection-molded plastic material, e.g. B. polyethylene. It has a modular structure, the module length being M and, in the present case, each comprising a bead 7, 8 running over part of the curvature. A single element 100 may include two, four, or more such modules. When laying the element 100 is arranged overlapping. For this purpose, it is nailed to the existing ridge screed. The ridge stones are then fastened with ridge clips, as is known in the usual ridge laying technique.

Unterhalb seiner äußeren Randbereiche 3, 4 ist das Element mit eindrückbaren Randstreifen 5, 6 unterfüttert, die sich auf die firstseitigen Dacheindeckungsplatten dichtend auflegen und dort für weitgehende Abdichtung gegen Wasser und Staub sorgen.Below its outer edge areas 3, 4, the element is lined with push-in edge strips 5, 6, which lie sealingly on the ridge-side roof covering panels and provide extensive sealing against water and dust there.

Das gewölbte Element 100 besitzt im Abstand von jeweils einer Modullänge M über einen Teil der Wölbung verlaufende Sicken 7, 8, die im Scheitelbereich des Elementes unterbrochen sind und in den übrigen Bereichen für eine Versteifung sorgen. Ferner sind auf der Sicke zahlreiche Auflager 10, 11 angebracht, deren Seitenflächen quer zur Firstrichtung stehen. Diese Auflager werden als "Flossen" bezeichnet, da sie die Form von aerodynamisch geformten flossenartigen Gebilden haben und dabei gleichzeitig die Funktion des Auflagers, zusammen mit der darunterliegenden Sicke 7, 8, erfüllen. Die Flossen 10, 11 sind in kammartigen Reihen oben auf den Sicken 7, 8 angeordnet und im vorliegenden Fall als ausgestülpte Hohlkörper gestaltet, wobei diese Form insbesondere dann gewählt wird, wenn die Firstabdichtungs- und -belüftungselemente 100 im Tiefziehverfahren hergestellt werden. Darüber hinaus sind die Flossen 9 als auf der Wölbungsfläche ruhende Kammstege gestaltet. Die Flossen 9 stehen über den Elementseiten nach außen über und haben einen Abstand von der Firstlinie, so daß insgesamt das Element 100 um die Firstlinie herum gebogen bzw. gewölbt werden kann, wenn die schweren Firststeine aufliegen.The arched element 100 has beads 7, 8 running at a distance of one module length M each over a part of the curvature, which are interrupted in the apex region of the element and provide stiffening in the other regions. Furthermore, numerous supports 10, 11 are attached to the bead, the side surfaces of which are transverse to the ridge direction. These supports are referred to as "fins" because they have the shape of aerodynamically shaped fin-like structures and at the same time the function of the support, together with the underneath bead 7, 8. The fins 10, 11 are arranged in comb-like rows on top of the beads 7, 8 and, in the present case, are designed as inverted hollow bodies, this shape being selected in particular when the ridge sealing and ventilation elements 100 are produced using the deep-drawing process. In addition, the fins 9 are designed as comb webs resting on the arch surface. The fins 9 project beyond the element sides and are at a distance from the ridge line, so that the element 100 can be bent or arched around the ridge line when the heavy ridge stones lie on it.

Ein weiteres Merkmal der Firstabdichtungs- und -belüftungselemente 100 bilden Belüftungsöffnungen 16, 17. Die Belüftungsöffnungen 16, 17 sind jeweils paarig, je einer Modullänge zugeordnet spiegelbildlich zu beiden Seiten der Firstlinie (-.-.-.) liegend ausgebildet. Es handelt sich im vorliegenden Falle um etwa rechteckige Öffnungen, deren längere Seite parallel zum First verläuft. Die Lüftungsöffnungen 16, 17 sind von einer nach oben überstehenden Randwulst 19 umgeben, die verhindert, daß Wasser in die Öffnungen 16 bzw. 17 einfließen kann.A further feature of the ridge sealing and ventilation elements 100 is formed by ventilation openings 16, 17. The ventilation openings 16, 17 are each formed in pairs, each assigned to a module length, as a mirror image on both sides of the ridge line (-.-.-.). In the present case, these are roughly rectangular openings, the longer side of which runs parallel to the ridge. The ventilation openings 16, 17 are surrounded by an upstanding bead 19, which prevents water from flowing into the openings 16 and 17, respectively.

In der Figur 1 sind zwei Ausführungsformen derartiger Belüftungsöffnungen dargestellt. Während es sich bei der Öffnung 16 um eine einfache, durchgestanzte Öffnung mit Randwulst handelt, ist bei der Öffnung 17 die Lüftungsöffnung zur Firstseite hin nach unten von einem überragenden Rand 18 umgeben. Weiterhin ist der untere Rand zusammen mit einem Boden so ausgebildet, daß eine Wanne gebildet ist, die etwa 2 - 6 cm unterhalb der oberen Wölbungsfläche ihren Tiefpunkt hat. Der Boden 21 und/oder die Ränder 18 sind mit Lüftungsperforationen 22, 23 ausgestattet, die für eine ausreichende Belüftung im Firstbereich sorgen. Jeweils in Längsrichtung gesehen können drei oder vier derartiger Perforationen 22, 23 vorgesehen sein.FIG. 1 shows two embodiments of such ventilation openings. While the opening 16 is a simple, punched-through opening with an edge bead, the ventilation opening at the opening 17 is surrounded by a protruding edge 18 toward the ridge side. Furthermore, the lower edge is formed together with a bottom in such a way that a trough is formed which has its low point approximately 2-6 cm below the upper arch surface. The bottom 21 and / or the edges 18 are provided with ventilation perforations 22, 23, which ensure adequate ventilation in the ridge area. Seen in the longitudinal direction, three or four such perforations 22, 23 can be seen be provided.

In den Figuren 2 und 3 ist ein weiteres gewölbtes Firstabdichtungs- und -belüftungselement 200 dargestellt, das unter einer Reihe von Firststeinen 1 üblicher Form anzuordnen ist.FIGS. 2 and 3 show a further curved ridge sealing and ventilation element 200, which is to be arranged under a row of ridge stones 1 of the usual shape.

Das Firstabdichtungs- und -belüftungselement 200 ist aus einer eingefärbten, 1 - 3 mm dicken Kunststoffolie oder aus einem entsprechenden, gespritzten Kunststoffmaterial hergestellt. Es ist modulartig aufgebaut, wobei die Modullänge M beträgt und diese wiederum etwa der halben Firststein-Länge entspricht. Ein einzelnes Element 200 kann zwei, zweieinhalb oder drei derartiger Module aufnehmen. Beim Verlegen wird das Element vorzugsweise überlappend angeordnet. Es wird hierzu jeweils auf die vorhandene Firstbohle 2 aufgenagelt. Die Firststeine werden dann mit (nicht dargestellten) Firstklammern befestigt, wie dies bei der üblichen Firstverlegetechnik bekannt ist.The ridge sealing and ventilation element 200 is made from a colored, 1-3 mm thick plastic film or from a corresponding, injection-molded plastic material. It has a modular structure, the module length being M and this in turn corresponding to approximately half the ridge length. A single element 200 can accommodate two, two and a half, or three such modules. When laying the element is preferably arranged overlapping. For this purpose, it is nailed onto the existing ridge screed 2. The ridge stones are then fastened with ridge brackets (not shown), as is known in the conventional ridge laying technique.

Unterhalb seiner äußeren Randbereiche 3, 4 ist das Element mit eindrückbaren Randstreifen 5, 6 unterfüttert, die sich auf die firstseitigen Dacheindeckungsplatten dichtend auflegen und dort für weitgehende Abdichtung gegen Wasser und Staub sorgen.Below its outer edge areas 3, 4, the element is lined with push-in edge strips 5, 6, which lie sealingly on the ridge-side roof covering panels and provide extensive sealing against water and dust there.

Das gewölbte Element 200 besitzt im Abstand von jeweils einer halben Modullänge M über die Wölbung verlaufende Sicken 7', 8', die für eine Versteifung sorgen. Ferner sind auf der konvex gewölbten Außenseite zahlreiche Flossen angebracht, deren Seitenflächen quer zur Firstrichtung stehen. Die Flossen sind im vorliegenden Falle als ausgestülpte Hohlkörper gestaltet, wobei diese Form insbesondere dann gewählt wird, wenn die Firstabdichtungs- und -belüftungselemente 200 im Tiefziehverfahren hergestellt werden. Aus Vollmaterial werden die Flossen dann hergestellt sein, wenn das Element 200 im Spritzgußverfahren produziert wird.The arched element 200 has beads 7 ', 8' which run over the curvature at intervals of half a module length M and which provide stiffening. Furthermore, numerous fins are attached to the convexly curved outside, the side surfaces of which are transverse to the ridge direction. In the present case, the fins are designed as inverted hollow bodies, this shape being chosen in particular when the ridge sealing and ventilation elements 200 are produced using the deep-drawing process. The fins are made of solid material be made when the element 200 is injection molded.

Wie erkennbar, sind die Flossen 10 teilweise in kammartigen Reihen 14 angeordnet, die sich über die Wölbung des Elementes 200 erstrecken. Um insbesondere den Lufteintritt im Kantenbereich bei aufgelegten Firststeinen zu erleichtern, sind die Flossen 9 entlang der Elementkante angeordnet; sie stehen auch über die Kante nach außen vor. Die Randbereiche 3, 4 des dargestellten Firstabdichtungs- und -belüftungselementes 200 sind treppenartig abgestuft, wobei sich Stufen 15 jeweils von einer Höhe und Breite von etwa 8 - 20 mm ergeben. Diese Abstufungen ermöglichen es, daß jeweils entlang einer Stufenkante geschnitten wird, wobei dieser Schnitt schon beim Hersteller, jedoch auch später erfolgen kann und dadurch schmalere Elemente ergibt, die an entsprechend schmalere Firststeine angepaßt sind.As can be seen, the fins 10 are partially arranged in comb-like rows 14 which extend over the curvature of the element 200. The fins 9 are arranged along the edge of the element in order in particular to facilitate the air entry in the edge area when the ridge tiles are in place; they also protrude outward beyond the edge. The edge regions 3, 4 of the ridge sealing and ventilation element 200 shown are stepped, steps 15 each having a height and width of approximately 8-20 mm. These gradations enable a cut to be made along a step edge, this cut being made by the manufacturer, but also later, and thereby resulting in narrower elements which are adapted to correspondingly narrower ridge stones.

Ein wesentliches Merkmal der Firstabdichtungs- und -belüftungselemente 200 bilden Belüftungsöffnungen 16', 17'. Die Belüftungsöffnungen 16', 17' sind jeweils paarig zu je zwei pro halber Modullänge spiegelbildlich zu beiden Seiten der Firstlinie liegend ausgebildet. Es handelt sich um etwa rechteckige Öffnungen, deren längere Seite parallel zum First verläuft. Die Lüftungsöffnungen sind von einer nach oben überstehenden Randwulst 19 umgeben, die verhindert, daß Wasser in die Öffnung 16' bzw. 17' einfließen kann. Dabei ist die Randwulst zum First hin schiffsbugartig vorgewölbt bzw. geformt, wobei verhindert wird, daß Wasser gestaut wird. Der Randsteg ist jedoch nur so hoch bemessen, daß die Belüftung im übrigen nicht behindert wird. Weitere Flossen 11 sind jeweils noch direkt im Scheitelbereich angeordnet und nehmen das Gewicht des Firststeines in diesem Bereich auf.An essential feature of the ridge sealing and ventilation elements 200 are ventilation openings 16 ', 17'. The ventilation openings 16 ', 17' are each formed in pairs, each mirroring the half length of the module, lying on both sides of the ridge line. These are roughly rectangular openings, the longer side of which runs parallel to the ridge. The ventilation openings are surrounded by an upstanding bead 19, which prevents water from flowing into the opening 16 'or 17'. The edge bead is bulged or shaped toward the ridge like a ship's bow, preventing water from being stowed. However, the edge web is only dimensioned so high that the ventilation is otherwise not hindered. Further fins 11 are each arranged directly in the apex area and take up the weight of the ridge stone in this area.

Schließlich ist noch möglich, kastenförmige Flugschneesammler 20 von oben in die Belüftungsöffnungen 16', 17' einzustecken. Durch seine spezielle Kammerausformung wird ein Eindringen von Flugschnee in den Bodenraum verhindert. Bei Tauwetter schmilzt der gesammelte Flugschnee und sammelt sich in einer Bodenwanne, so daß er dort verdunsten kann. Der Flugschneesammler ist mit zahlreichen, lamellenartig abgedeckten Seitenöffnungen ausgestattet, die gewährleisten, daß der Lüftungsquerschnitt der Belüftungsöffnung 17' im wesentlichen voll erhalten bleibt. Derartige Flugschneesammler werden in etwas vergrößerter Form vom Anmelder angeboten. Für den vorliegenden Fall ist eine speziel]e Anpassung, insbesondere Verkleinerung, der bekannten Flugschneesammler erforderlich.Finally, it is still possible to insert box-shaped flying snow collector 20 from above into the ventilation openings 16 ', 17'. Due to its special chamber shape, flying snow cannot penetrate into the floor space. In the case of thaw, the collected flying snow melts and collects in a floor pan so that it can evaporate there. The flying snow collector is equipped with numerous, lamellar covered side openings, which ensure that the ventilation cross section of the ventilation opening 17 'is essentially fully preserved. Such fly snow collectors are offered by the applicant in somewhat enlarged form. In the present case, a special adaptation, in particular downsizing, of the known snow drift collectors is required.

In den Figuren 4a und 4b ist ein Firstabdichtungs- und -belüftungselement in einer dritten Ausführungsform, Bezugszahl 300, dargestellt. Das Element 300 wird unter einer Reihe von Firststeinen üblicher Form angeordnet. Während es nach der Fertigung zunächst eine plane Form hat (Figur 4b) bildet sich eine Wölbungsfläche unter der Last der Firststeine aus. Das Element 300 ist aus einer eingefärbten, 1 - 3 mm dicken Kunststoffolie, wie bei den anderen Ausführungsbeispielen, ausgebildet. Es ist ebenfalls modulartig aufgebaut, wobei die Modullänge M beträgt und im vorliegenden Fall jeweils einen im Firstbereich angeordneten Hohlsockel 30 umfaßt. Der Hohlsockel nimmt eine Breite von etwas mehr als die Firstbohlenbreite ein. In seine Oberseite sind Belüftungsöffnungen 16 eingeschnitten, die jeweils spiegelbildlich zu beiden Seiten der Firstlinie verlaufen. Weiterhin sind an den vier Ecken des Hohlsockels 30 vier Abstandsnoppen 31 aufgesetzt, die nach oben stehen. Auf diesen Abstandsnoppen 31 ruht die Innenseite des aufliegenden Firstabdeckelementes im Bereich des Scheitels. Um die Hohlsockel 30 nach innen zur Firstlatte hin abzustützen, sind ferner noch zwischen den Lüftungsöffnungen 16 liegende Abstandsnocken 34 vorgesehen. Weiterhin sind die Hohlsockel mit jeweils zwei in Firstrichtung verlaufenden Stegen 32 verbunden. Seitlich zu den Hohlsockeln 30 ist Element 300 an seinen Seiten mit Flossen 9 versehen, die zum Scheitel hin ausgerichtet sind. Es handelt sich dabei um ähnliche Elemente wie die der Bezugszahl 9 gemäß Figur 1. Zum Unterschied dazu sind die Elemente an ihrer Innenseite schräg nach innenlaufend abgeschnitten (Schräge 33). Der Bereich zwischen der Schräge 33 und der Außenseite der Hohlsockel, bezeichnet mit "K", stellt einen Knickbereich dar, der nicht so stark belastet ist, wenn die Firststeine aufliegen und der damit die Wölbungsfläche erzeugt, die das Firstabdichtungsund -belüftungselement 300 kompatibel zu 30 den gewölbten Firststeinen macht.A ridge sealing and ventilation element in a third embodiment, reference number 300, is shown in FIGS. 4a and 4b. The element 300 is arranged under a row of ridge stones of conventional shape. While it initially has a flat shape after production (FIG. 4b), a curved surface is formed under the load of the ridge stones. The element 300 is formed from a colored, 1-3 mm thick plastic film, as in the other exemplary embodiments. It is also constructed in a modular manner, the module length being M and, in the present case, each comprising a hollow base 30 arranged in the ridge area. The hollow base has a width of slightly more than the ridge plank width. In its upper side, ventilation openings 16 are cut, each of which runs in mirror image on both sides of the ridge line. Furthermore, four spacer knobs 31 are placed on the four corners of the hollow base 30, which protrude upwards. The inside of the ridge covering element lying on it rests in the region of the apex on these spacer knobs 31. To the hollow base 30 inward towards the ridge batten, spacing cams 34 are also provided between the ventilation openings 16. Furthermore, the hollow bases are each connected to two webs 32 running in the ridge direction. To the side of the hollow bases 30, element 300 is provided on its sides with fins 9 which are oriented towards the apex. These are similar elements to that of reference number 9 according to FIG. 1. In contrast to this, the elements on their inside are cut obliquely inwards (bevel 33). The area between the bevel 33 and the outside of the hollow base, denoted by "K", represents a kink area which is not so heavily loaded when the ridge stones lie on it and which thus produces the arch surface which the ridge sealing and ventilation element 300 is compatible with 30 the domed ridge stones.

Wesentlich ist, daß auch hier die Flossen 9 seitlich über die Außenkante der Flügelteile des Elementes überstehen. Damit wird ausgeschlossen, daß die aufliegenden, schweren Firststeine mit ihrem Rand bis auf die Außenkante zu liegen kommen und den Quer-Luftstrom unterbrechen.It is essential that the fins 9 protrude laterally beyond the outer edge of the wing parts of the element. This prevents the heavy ridge stones lying on top from resting on the outer edge and interrupting the cross-air flow.

Das Element gemäß Figuren 4a und 4b kann in vorteilhafter Weise in einfach zu erstellenden Kunststoff-Werkzeugen gespritzt oder tiefgezogen werden, wobei zunächst eine plane Form gemäß Figur 4b erzeugt wird, die erst im Anwendungsfall sich nach unten wölbt. Im Bereich der Firstbohle erfolgt keine Trennung des Luftstromes, da die nach unten und oben stehenden Nocken bzw. Noppen einen ungehinderten Luftstrom auch quer zur Firstlatte erfolgen lassen.The element according to FIGS. 4a and 4b can advantageously be injection molded or deep-drawn in plastic tools that are easy to create, a plane shape according to FIG. 4b initially being produced, which bulges downward only in the application. There is no separation of the air flow in the area of the ridge screed, since the cams or knobs standing up and down allow an unimpeded air flow to take place transversely to the ridge batten.
