Abstract

The clasp (3), on engaging over the roof pantile with the stirrup, engages behind the roof lath with which it forms a positive engagement. The connection of the clasp with the stirrup to form a structural unit is by a rib (6), the profile of which is reinforced against bending. The quadratic to rectangular profile of the stirrup is reinforced at least along the stirrup rib with a rib profile. The rib profile, starting from the root of the rib (8) of the stirrup, reaches over a part (1) of the stirrup arm. The structural unit comprising clasp and stirrup is E-shaped.

Description

Die Erfindung betrifft eine Dachpfannensicherung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a roof tile fuse according to the preamble of claim 1.

Derartige Dachpfannensicherungen bezwecken, das Abheben der Dachpfannen von den Dachlatten zu verhindern, vor allem, wenn erhebliche Windkräfte auf die Dachpfannen einwirken, die z.B. mit Vorsprüngen an ihrer Unterseite formschlüssig auf den Dachlatten aufliegen. Erfindungsgemäß werden dazu Bügel verwendet, die die Dachpfannen zusätzlich auf den Dachlatten halten und dadurch dem Abheben der Vorsprünge von den Dachlatten entgegenwirken. Diese Bügel werden in aller Regel beim Eindecken des Daches angebracht und liegen im fertigen Dach unter der Eindeckung, weil sie auf die den Dachlatten zugekehrten Kanten der Pfannen drücken.Such roof tile protections are intended to take off to prevent the roof tiles from the battens especially when there are significant wind forces on the roof tiles act, e.g. with protrusions on hers Place the underside positively on the roof battens. According to the invention, brackets are used for this additionally hold the roof tiles on the roof battens and thereby lifting the projections from the roof battens counteract. These hangers are used in everything Usually attached and lying when covering the roof in the finished roof under the covering because it is on the edges of the pans facing the roof battens to press.

Es ist bereits bekannt, Dachpfannen auf diese Weise zusätzlich auf den Dachlatten zu halten, die bislang nur mit ihrem Auflagegewicht gegen das Abheben oder Abrutschen von den Dachlatten gesichert sind. Dazu verwendet man Bügel in Form von Krampen, die mit einem Schenkel in die Dachlatte eingetrieben werden und mit ihrem anderen Schenkel auf die Dachpfannen in der beschriebenen Weise einwirken. Solche allgemein U-förmigen Bügel müssen aus Metall bestehen, wozu man in der Regel Stahldrahtabschnitte verwendet, die an einem Ende eines ihrer U-Schenkel angespitzt werden, um das Eintreiben in die Dachlatte zu erleichtern.It is already known to tile this way additionally to keep on the roof battens that so far only with their weight against lifting or Slipping off the roof battens are secured. To one uses brackets in the form of cramps with one leg are driven into the roof batten and with her other leg on the roof tiles act as described. Such in general U-shaped brackets must be made of metal, which is why usually used steel wire sections that to be pointed at one end of one of her U-legs, to facilitate driving into the roof batten.

Bei den üblichen Stahlqualitäten und den bislang als ausreichend angesehenen Drahtstärken der krampenförmigen Bügel zeigt sich indessen, daß bei den auftretenden Sogkräften, die die Windbelastung der Dacheindeckung an den Dachpfannen erzeugt, die von der Sicherung ausgeübten Druckkräfte nicht ausreichen. Die Dachpfannensicherung durch die beschriebenen Krampen ist daher unbefriedigend. Die Handhabung solcher Dachpfannensicherungen ist zudem vergleichsweise aufwendig, da das Einschlagen der Krampen wegen der U-Form und der Elastizität des Stahldrahtes besonders dann schwierig wird, wenn der notwendige vorschriftsmäßige Sitz in der Dachlatte und auf den Dachpfannen erreicht werden soll. Diese Schwierigkeit vergrößert sich noch erheblich, wenn die Dacheindeckung nachträglich durch Verschieben einzelner Pfannen korrigiert werden muß, was häufig vorkommt. Dann muß unter Umständen eine Reihe zunächst eingeschlagener Krampen wieder gelöst und durch neu eingeschlagene Bügel ersetzt werden, wobei häufig die zunächst eingeschlagenen Krampen verlorengehen. With the usual steel grades and so far as sufficiently regarded wire thicknesses of the cramped Temple shows, however, that in the occurring Suction forces affecting the wind load of the roof covering generated on the roof tiles by the fuse applied pressure forces are not sufficient. The Roof tile protection through the described staples is therefore unsatisfactory. The handling of such Roof tile protection is also comparatively complex, because the cramping is due to the U-shape and the elasticity of the steel wire particularly then becomes difficult when the necessary proper Seat in the roof batten and on the roof tiles should be achieved. This difficulty increases still significant when the roof covering is added corrected by moving individual pans must be what often happens. Then under Possibly a series of cramps that were initially driven in loosened again and replaced with new brackets will be, often the first struck Staples are lost.

Desweiteren ist aus der DE-U-90 16 795 eine Befestigungsklammer für Dachpfannen oder -platten bekannt, die als U-förmige Klammer ausgeführt ist, wobei die beiden Schenkel der Klammer die Dachpfanne und Dachlatte umgreifen und über eine Federkraft aneinanderpressen, so daß eine kraftschlüssige Verbindung zwischen Dachpfanne und Dachlatte entsteht.Furthermore, DE-U-90 16 795 is a fastening clip for roof tiles known or plates, which is designed as a U-shaped bracket, wherein the two legs of the clamp embrace the roof tile and the batten and press against each other via a spring force, so that a non-positive connection between the roof tile and the batten.

Zusätzlich weist die Befestigungsklammer nach DE-U-90 16 795 an dem an der Dachlatte liegenden Schenkel eine kopfartige Abkantung auf, die zusätzlich einen Formschluß zwischen Dachlatte und Befestigungsklammer erzeugt. Der wesentliche Nachteil dieser Befestigungsklammer ist jedoch darin zu sehen, daß durch die formschlüssige Verbindung zwischen Dachlatte und Befestigungsklammer diese nur für diejenigen Dächer einsetzbar ist, bei denen die Abmessungen der Dachlatte und der Dachpfanne auf die Abmessungen der Befestigungsklammer abgestimmt sind.In addition, the mounting bracket according to DE-U-90 16 795 on the at Legs lying on the roof batten have a head-like bend, which also has a Form-fit generated between the roof batten and the mounting bracket. The essential The disadvantage of this mounting bracket is, however, that due to the positive connection between the roof batten and the fastening clip this can only be used for those roofs where the dimensions the roof batten and the roof tile to the dimensions of the mounting bracket are coordinated.

Die Erfindung geht einen anderen Weg, dessen Grundgedanke im Anspruch 1 wiedergegeben ist. Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche.The invention takes a different approach, the basic idea of which is reproduced in claim 1. Other features the invention are the subject of the dependent claims.

Gemäß der Erfindung erfolgt die Anbringung des Bügels durch eine Spange, wodurch die aus Bügel und Spange bestehende Baueinheit gleichzeitig die Dachpfanne mit dem Bügel übergreift und die Dachlatte hintergreift, um die Baueinheit kraftschlüssig festzulegen, wobei für den Kraftschluß eine der bislang nicht ausgenutzten Seiten, z.b. die Rückseite der Dachlatte verwendet wird. Dazu benötigt man in aller Regel kein besonderes Werkzeug. Durch die entgegengesetzte Bewegung lassen sich die Spange und der Bügel wieder entfernen und gegebenenfalls wiederverwenden. According to the invention, the bracket is attached through a clasp, which makes the strap and clasp existing unit simultaneously with the roof tile reaches over the bracket and reaches behind the roof batten, in order to determine the structural unit non-positively, whereby one of the previously unused for the adhesion Pages, e.g. used the back of the roof batten becomes. Usually you don't need anything special Tool. By the opposite movement the clasp and the bracket can be removed and reuse if necessary.

Es hat sich überraschend herausgestellt, daß die aus der Spange und dem Bügel bestehende Baueinheit eine erheblich höhere Formsteifigkeit aufweisen kann, die stärkere Haltekräfte auf die Dachpfanne ausübt als es mit den Drahtkrampen bislang möglich gewesen ist. Diese Formsteifigkeit läßt sich weiter steigern, wenn man die aus Spange und Bügel bestehende Baueinheit mit den Merkmalen des Anspruches 2 profiliert. In diesem Fall erhält man nämlich ein in der Hauptbiegerichtung erhöhtes Widerstandsmoment. Die dadurch erzielte verstärkte Sicherung läßt sich mit den Merkmalen des Anspruches 3 weiter verbessern, insbesondere wenn auch noch von den Merkmalen des Anspruches 4 Gebrauch gemacht wird. Denn hierdurch erhält man nicht nur ein günstiges Stegprofil, sondern auch noch eine Verstärkung am eingespannten Ende des Bügelschenkels, der auf die Dachpfanne drückt.It has surprisingly been found that the out the clasp and the bracket existing unit can have significantly higher stiffness exerts stronger holding forces on the roof tile than it does has been possible with the wire staples so far. This stiffness can be further increased if one the assembly consisting of clasp and bracket profiled with the features of claim 2. In in this case you get one in the main bending direction increased section modulus. The thereby achieved increased security can be with the features of claim 3 further improve, in particular if still use the features of claim 4 is made. Because this doesn't get you just a cheap web profile, but also one Reinforcement at the clamped end of the stirrup leg, that presses on the roof tile.

Wie sich insbesondere ergeben hat, läßt sich mit der Erfindung nunmehr eine Dachpfannensicherung verwirklichen, die nicht mehr auf die Verwendung von Metall, insbesondere von Stahldraht für den Bügel beschränkt ist. Vielmehr können Baueinheiten der erfindungsgemäßen Art außer aus Metall unbedenklich auch aus thermoelastischen Kunststoffen, wie etwa Polyethylen oder Polyvinylchlorid hergestellt, d.h. insbesondere in Spritzgußformen gefertigt werden. Das ermöglicht eine auf die Funktion der Spange und des Bügels abgestellte optimale Formgebung, die im Ergebnis dazu führt, daß eine bis zu 80 % höhere Durchbiegungslast der Baueinheit gegenüber dem vorbekannten Drahtbügel erzielt werden kann.As has emerged in particular, the Invention now realize a roof tile protection, who no longer rely on the use of metal, particularly limited by steel wire for the bracket is. Rather, units of the invention Kind in addition to made of metal thermoelastic plastics, such as polyethylene or polyvinyl chloride, i.e. in particular are manufactured in injection molds. This allows one geared to the function of the clasp and the bracket optimal shape, the result of this leads to an up to 80% higher deflection load the unit compared to the previously known wire bracket can be achieved.

Insbesondere tragen dazu die Merkmale des Anspruches 5 bei. Denn hierbei wird durch die E-Form der aus Spange und Bügel bestehenden Baueinheit eine bessere Umklammerung der Dachlatte bei gleichzeitig verbesserter Formsteifigkeit der Dachpfannensicherung gemäß der Erfindung erzielt.In particular, the features of the claim contribute to this 5 at. Because here the E-shape turns the Clasp and bracket existing unit better Clasping the roof batten with improved at the same time Dimensional rigidity according to the roof tile protection achieved the invention.

Die Festlegung der Spange auf der Dachlatte hängt natürlich hauptsächlich von der Reibung ab, welche vornehmlich an der Unterseite der Dachlatte dem Abziehen der Spange entgegenwirkt. Da hiervon zugleich die Stärke der Dachpfannensicherung abhängt, empfiehlt es sich, reibungserhöhende Mittel insbesondere gemäß den Merkmalen des Anspruches 6 vorzusehen. Solche Mittel können im übrigen weitgehend unabhängig von dem Werkstoff, der für die Dachpfannensicherung gewählt wird, nach Anspruch 7 ausgebildet sein. Die hierbei vorgesehene Verzahnung erhöht die Reibung noch erheblich, wenn sie entsprechend den Merkmalen des Anspruches 8 ausgebildet wird.The fixing of the clasp on the roof batten naturally depends mainly on the friction, which mainly peeling off at the bottom of the roof batten counteracts the clasp. Since at the same time the It depends on the strength of the roof tile protection himself, friction-increasing means in particular according to the Provide features of claim 6. Such means can be largely independent of the material, which is chosen for the roof tile protection, be formed according to claim 7. The one provided here Gearing significantly increases friction, if they correspond to the features of claim 8 is trained.

Gemäß einer weiteren Ausführungsform der Erfindung (Anspruch 12) ermöglicht die neue Dachpfannensicherung nicht nur die Festlegung der übergriffenen Dachpfanne mit dem Bügel, sondern auch die diese Dachpfanne mindestens teilweise überdeckende Dachpfanne wird von dem gleichen Bügel festgehalten, wofür der Bügel mit einem zusätzlichen Niederhalter versehen ist. Das bedeutet, daß in der Dacheindeckung die Ober- und die Unterkanten aller Dachpfannen bei konsequenter Anbringung der erfindungsgemäßen Dachpfannensicherung gegen Abheben von den Dachlatten gesichert sind.According to a further embodiment of the invention (Claim 12) enables the new roof tile protection not just the definition of the overlapped roof tile with the bracket, but also this roof tile roof tile covering at least partially is held by the same bracket for which the Provide bracket with an additional hold-down device is. That means that in the roof covering the Upper and lower edges of all roof tiles with consistent Attachment of the roof tile protection according to the invention secured against lifting off the roof battens are.

Die Erfindung hat daher den Vorteil, daß die Dachpfannen auch bei extremen Windbelastungen auf dem Dach liegen bleiben und Dachschäden weitgehend ausgeschlossen werden können. Das geschieht durch den mit dem Bügel zusammenwirkenden Niederhalter, der im Vergleich mit der einfachen Dachpfannensicherung nach dem Hauptpatent grundsätzlich keinen größeren Fertigungs- und Materialaufwand bedeutet.The invention therefore has the advantage that the roof tiles even with extreme wind loads on the The roof remains lying and roof damage is largely excluded can be. That happens with the the clamp interacting hold-down, which in comparison with the simple roof tile protection the main patent basically no major manufacturing and material expenditure means.

Es ist zweckmäßig, die Erfindung mit den Merkmalen des Anspruches 13 zu verwirklichen, da hiermit bereits bei Anbringung der Dachpfannensicherung auf der Dachlatte der Niederhalter in seine Ausgangsstellung zur Sicherung der aufliegenden Dachpfanne gebracht wird. Das ist dadurch möglich, daß der Niederhalter und die Baueinheit aus dem Bügel und der Spange in einem einteiligen Formkörper auch den Niederhalter enthält.It is useful to the invention with the features of claim 13 to implement, since hereby already when installing the roof tile protection on the The hold down roof batten in its initial position brought to secure the overlying roof tile becomes. This is possible because the hold-down device and the assembly from the bracket and the clasp in a one-piece molded body also the hold-down device contains.

In der Regel ist es zweckmäßig, aber auch ausreichend, die aufliegende Dachpfanne kraftschlüssig mit dem Niederhalter festzulegen. Dies geschieht mit den Merkmalen des Anspruches 14 durch Ausbildung des Niederhalters als Klemme, welche die freie Kante der aufliegenden Dachpfanne übergreift.As a rule, it is useful, but also sufficient, the overlay roof tile with non-positively the hold-down. This happens with the Features of claim 14 by training the hold-down as a clamp, which the free edge of the overlaps the roof tile.

Obwohl man auch in einer Baueinheit die Klemme als eigene Baugruppe ausbilden kann, bedeutet es eine Vereinfachung des Bügels, wenn die bereits vorhandenen Teile für die Klemme ausgenutzt werden können. Daher ist die Merkmalgruppe des Anspruches 15 zweckmäßig, weil hierbei die Klemme den Bügelsteg nutzt, um die Klemmwirkung herbeizuführen.Although the clamp is also used as a unit can form their own assembly, it means one Simplify the temple if the already existing Parts for the clamp can be used. Therefore, the group of features of claim 15 is appropriate because the clamp uses the stirrup, to bring about the clamping effect.

Besonders einfach gestaltet sich die Erfindung, wenn man in der Klemme einen offenen Haken vorsieht, der gemäß dem Merkmal des Anspruches 16 die Kante der aufliegenden Dachpfanne übergreift. Man kann dann nämlich die aufliegende Dachpfanne von oben nach unten in die Klemme einschieben und benötigt dann keinen weiteren Arbeitsgang, um den Kraftschluß herbeizuführen. Dabei ermöglicht die Tiefe des Hakenmaules den Ausgleich von Unterschieden in den Dachpfannen und ihrer Verlegung auf dem Dach.The invention is particularly simple if one provides an open hook in the clamp, which according to the feature of claim 16, the edge of the overlying Reaches over the roof tile. Then you can the roof tile from top to bottom insert into the clamp and then does not need any further operation to bring about the adhesion.

Die bei 1 in Fig. 1 dargestellte Dachpfannensicherung weist in Baueinheit einen Bügel 2, der zum Halten einer nicht dargestellten Dachpfanne auf einer Dachlatte dient, und eine Spange 3 auf, welche die Baueinheit 1 auf der Dachlatte hält. Die Baueinheit wird nach Auflegen der Dachpfanne auf die Dachlatte über die obere Kante der Dachpfanne und die Dachlatte aufgeschoben und untergreift mit ihrem Außenschenkel 4 die Dachlatte. Mit der Innenseite 5 geht sie eine kraftschlüssige Verbindung mit der Unterseite der Dachlatte ein.The roof tile protection shown at 1 in Fig. 1 has a bracket 2 in the unit, which for holding a roof tile, not shown, on a roof batten serves, and a clasp 3, which the unit 1 holds on the roof batten. The unit is after placing the roof tile on the roof batten the top edge of the roof tile and the roof batten pushed on and reaches under with its outer leg 4 the roof batten. With the inside 5 it goes one positive connection with the bottom of the Roof batten.

Die Verbindung der Spange und des Bügels in der Baueinheit 1 erfolgt durch einen Steg 6, dessen Profil gemäß dem Ausführungsbeispiel gegen Durchbiegung nach oben, d.h. in Abheberichtung der Dachpfanne und damit in Hauptbiegerichtung verstärkt ist. Zur Verstärkung des Steges 6, der gemäß dem Ausführungsbeispiel ein quadratisches bis rechteckiges Profil aufweist, dient eine Rippe 7, die ebenfalls ein allgemein rechteckiges Profil aufweist, die jedoch an ihrer mit der Oberseite des Stegprofiles 6 gemeinsamen Unterseite schmaler als der Steg ausgebildet ist, also eine geringere Breite b als die Breite B des Steges 6 in dieser Dimension aufweist. Die Anordnung der beiden miteinander verschmolzenen Steg- und Rippenprofile ist aber so getroffen, daß sich eine zentralsymmetrische Anordnung des Rippenprofils auf dem Stegprofil ergibt. Senkrecht zur Zeichenebene der Fig. 2 entsteht dadurch ein verstärktes Widerstandsmoment des Steges 6 in der Hauptbiegerichtung.The connection of the clasp and the bracket in the assembly 1 is done by a web 6, the profile according to the embodiment against deflection after above, i.e. in the lifting direction of the roof tile and thus is reinforced in the main bending direction. For reinforcement of the web 6, which according to the embodiment has a square to rectangular profile a rib 7, which is also a generally rectangular Has profile, but at their with the Top of the web profile 6 common bottom is narrower than the web, that is, a smaller one Width b as the width B of the web 6 in this dimension. The arrangement of the two fused web and rib profiles but is such that there is a centrally symmetrical Arrangement of the rib profile on the web profile results. Perpendicular to the drawing plane of FIG. 2 arises thereby an increased section modulus of the Web 6 in the main bending direction.

Das Rippenprofil erstreckt sich gemäß dem Ausführungsbeispiel nicht nur über die Länge L des Steges 6, sondern auch über eine gewisse Länge des Außensteges 8 des Bügels in der Baueinheit 1. Diese Länge bildet die Stegwurzel 9 und ist in Fig. 1 mit 1 bezeichnet. Hierdurch wird auch das Widerstandsmoment des Bügelschenkels 8 an der Einspannstelle in den Steg 6 verstärkt und die Haltekraft auf die Dachpfanne vergrößert.The rib profile extends according to the embodiment not just over the length L of the web 6, but also over a certain length of the outer web 8 of the bracket in the assembly 1. This length forms the web root 9 and is designated by 1 in FIG. 1. This also means the section modulus of the bracket leg 8 at the clamping point in the Web 6 reinforced and the holding force on the roof tile enlarged.

Insgesamt ergibt sich dadurch eine allgemein E-förmige, aus der Spange 3 und dem Bügel 2 bestehende Baueinheit 1, wobei die Spange 3 einen längeren Außenschenkel 4 und einen Zwischenschenkel 10 umfaßt, während der andere, kürzere Außenschenkel 8 des Bügels 2 die Dachpfanne übergreift und der Formrücken von dem Steg 6 und der Rippe 7 gebildet wird. Der Zwischenschenkel 10 untergreift die Dachpfanne und legt sich auf die Oberseite der Dachlatte. Zur Erleichterung des Aufschiebens der Baueinheit 1 auf die Dachpfanne und die Dachlatte ist der Zwischenschenkel 10 mit einer Schneide 11 versehen. Overall, this results in a generally E-shaped, consisting of the clasp 3 and the bracket 2 Unit 1, the clasp 3 a longer one Includes outer leg 4 and an intermediate leg 10, while the other, shorter outer leg 8 of the bracket 2 overlaps the roof tile and the back of the form is formed by the web 6 and the rib 7. The Intermediate leg 10 engages under the roof tile and lies on the top of the roof batten. To make things easier of postponing unit 1 on the Roof tile and the roof batten is the intermediate leg 10 provided with a cutting edge 11.

Die Innenseite des Außenschenkels 4 ist mit reibungserhöhenden Mitteln versehen. Diese befinden sich auf einer Rippe 12, deren ebenfalls rechteckiges Profil mit dem Rechteckprofil des Außenschenkels 4 vereinigt ist. Die reibungserhöhenden Mittel bestehen dabei aus einer Verzahnung 14, die gemäß dem dargestellten Ausführungsbeispiel als Schrägverzahnung ausgebildet ist. Diese Schrägverzahnung hat Zahnrücken 15, welche in Abzugsrichtung der Baueinheit 1 von der Dachpfanne und der Dachlatte ansteigend ausgebildet sind.The inside of the outer leg 4 is with provide friction-increasing agents. These are on a rib 12, which is also rectangular Profile with the rectangular profile of the outer leg 4 is united. The means to increase friction exist thereby from a toothing 14, which according to the illustrated Embodiment as helical teeth is trained. This helical toothing has tooth backs 15, which in the withdrawal direction of the unit 1 from the roof tile and the roof batten rising are.

Der in den Figuren dargestellte Gegenstand ist ein Formkörper, der vorzugsweise aus Kunststoff im Spritzgußverfahren hergestellt wird. Der thermoelastische Kunststoff läßt sich inert ausbilden, so daß Korrosionen der Dachpfannensicherung nicht zu befürchten sind. Die Haltekräfte, die die Baueinheit 1 auf die Dachlatten ausübt, sind außerordentlich hoch, so daß eine ausreichende Sicherung erreichbar ist. Es genügt daher, in der Regel für jede Dachlatte jeweils eine Baueinheit 1 vorzusehen. Sie wird nach Auflegen der Dachpfanne auf die Dachlatte von oben auf diese Teile aufgeschoben und hält sich dann kraftschlüssig mit ihrer Spange 3 auf der Dachlatte.The object shown in the figures is a Shaped body, which is preferably made of plastic in the Injection molding process is produced. The thermoelastic Plastic can be made inert, so that there is no fear of corrosion of the roof tile protection are. The holding forces that the assembly 1 on the roof battens are extremely high, so that adequate security can be achieved. It is therefore sufficient, usually for each roof batten to provide a structural unit 1. It will hang up the roof tile onto the roof batten from above on this Parts pushed on and then holds firmly with her clasp 3 on the roof batten.

Die allgemein mit 31 bezeichnete Dachpfannensicherung weist gemäß der Ausführungsform nach den Fig. 3 und 4 in Baueinheit einen Bügel 32 zum Halten einer auf einer Dachlatte A aufliegenden Dachpfanne B gegen abhebende Windkräfte auf und verwirklicht außerdem eine Spange 33, welche die Baueinheit 31 auf der Dachlatte A hält. Die Baueinheit wird nach Auflegen der Dachpfanne B auf die Dachlatte A aufgeschoben und untergreift mit ihrem Außenschenkel 34 die Dachlatte A.

Zur Verstärkung des Steges 36, der gemäß dem dargestellten Ausführungsbeispiel ein quadratisch bis rechteckiges Profil aufweist, dient eine Rippe 37, die ebenfalls ein allgemein rechteckiges Profil aufweist, jedoch an ihrer mit der Oberseite des Stegprofiles 36 gemeinsamen Unterseite schmaler als der Steg 36 ausgebildet ist, also eine geringere Breite als die Breite des Steges in dieser Dimension aufweist. Die Anordnung der beiden miteinander verschmolzenen Steg- und Rippenprofile ist aber so getroffen, daß sich eine zentralsymmetrische Anordnung des Rippenprofils auf dem Stegprofil ergibt. In der Zeichenebene entsteht dadurch ein verstärktes Widerstandsmoment des Steges 36 in der Hauptbiegerichtung, die durch die abhebende Tendenz der Dachpfannen von den Dachlatten gegeben ist.The connection of the clasp 33 and the bracket 32 in the Unit 31 takes place via a web 36, the profile according to the embodiment against bending upwards, i.e. in the lifting direction of the roof tile B and is therefore reinforced in the main bending direction. For Reinforcement of the web 36, which according to the illustrated Embodiment a square to rectangular Has a profile, a rib 37 is used also has a generally rectangular profile, however at their with the top of the web profile 36th common bottom formed narrower than the web 36 is a smaller width than that Has width of the web in this dimension. The Arrangement of the two fused webs and rib profiles is made so that a centrally symmetrical arrangement of the rib profile results on the web profile. In the drawing plane arises thereby an increased section modulus of the Web 36 in the main bending direction, through the lifting tendency of the roof tiles from the roof battens given is.

Das Rippenprofil erstreckt sich nicht nur über die Länge des Steges 36, sondern auch über eine gewisse Länge eines Außensteges 38 des Bügels 32. Diese Länge bildet die Stegwurzel 39. Hierdurch wird auch das Widerstandsmoment des Bügelschenkels 38 an der Einspannstelle in den Steg 36 verstärkt und die Haltekraft auf die Dachpfanne B vergrößert.The rib profile not only extends over the Length of the web 36, but also over a certain Length of an outer web 38 of the bracket 32. This length forms the bridge root 39. This also causes the section modulus of the bracket leg 38 at the clamping point reinforced in the web 36 and the holding force enlarged to the roof tile B.

Insgesamt ergibt sich insoweit eine allgemein E-förmige, aus der Spange 33 und dem Bügel 32 bestehende Baueinheit 31, wobei die Spange 33 einen der Dachpfanne B und der Dachlatte A in seiner Länge angepaßten Außenschenkel und einen Zwischenschenkel 40 umfaßt, während der andere Außenschenkel 38 die in der Dacheindeckung unterliegende Dachpfanne B übergreift und der Rücken des Formkörpers von dem Steg 36 und der Rippe 37 gebildet wird. Der Zwischenschenkel 10 liegt unter der Unterkante der Dachpfanne B und kommt an der Unterkante der Dachlatte A zur Anlage.Overall, this results in a generally E-shaped, consisting of the clasp 33 and the bracket 32 Unit 31, the clasp 33 one of the roof tile B and the roof batten A adjusted in length Outer leg and an intermediate leg 40 comprises, while the other outer leg 38 which in overlaps the roof tile B underneath and the back of the molded body from the web 36 and the rib 37 is formed. The intermediate leg 10 lies under the lower edge of the roof tile B and comes on the lower edge of the roof batten A to the system.
