Description

Die Erfindung betrifft ein extrudierbares Ein- oder Mehr­kammer-Profilelement nach dem Oberbegriff des Patentanspru­ches 1.The invention relates to an extrudable single or multi-chamber profile element according to the preamble of claim 1.

Profilelemente dieser Art sind an sich bekannt, beispiels­weise aus dem deutschen Patent 26 33 731. Ein solches Profil­element weist an seinen seitlichen Enden Verbindungselemente auf, durch die es mit Nachbarelementen gleicher Ausführungsform verbunden oder verklammert werden kann, so daß aus den Profil­elementen eine Dachfläche oder Bautafel zusammengesetzt wird. Derartige Profile werden überwiegend zur Bildung von Ober­lichtern, Lichtwänden und Lichtdächern eingesetzt. Bei der Ver­wendung für Lichtdächer tritt das Problem auf, daß besonders im Winter durch aufliegenden Schnee eine hohe Flächenbelastung auf die Profilelemente ausgeübt wird und die Gefahr besteht, daß sie sich nach innen durchbiegen. Das Element nach dem Deutschen Patent 26 33 731 weist zwar eine gekrümmte Ober- und Unterwand auf, diese Krümmung reicht bei großflächigen Bautafeln jedoch nicht aus, um den durch Schneeauflage hervorgerufenen Flächen­belastungen standzuhalten.Profile elements of this type are known per se, for example from German Patent 26 33 731. Such a profile element has connecting elements at its lateral ends, by means of which it can be connected or clamped to neighboring elements of the same embodiment, so that a roof surface or building board is formed from the profile elements is put together. Such profiles are mainly used to form skylights, light walls and skylights. When used for light roofs, the problem arises that, especially in winter, a high surface load is exerted on the profile elements by snow on top and there is a risk that they will bend inwards. The element according to German Patent 26 33 731 has a curved top and bottom wall, but this curvature is not sufficient for large-area building panels to withstand the surface loads caused by snow cover.

Einander benachbarte Profilelemente nach diesem Stand der Technik bilden mit ihren seitlichen Verbindungsstücken jeweils einen im wesentlichen rechteckförmigen Verriegelungskanal, in die ein bandartiges Riegelelement eingesetzt wird. An den Flä­chen, bei denen die Verbindungsstücke der benachbarten Elemente aneinanderliegen, bilden sich Kapillarspalte. Die Oberwand bei dem Verriegelungselement nach dem Stand der Technik ist nach außen konvex gekrümmt, so daß die Übergangsstelle zwischen der Oberwand und dem zugehörigen Verbindungsstück tiefer liegt als der restliche Teil der Oberwand. An dieser Übergangsstelle sam­melt sich somit bei Regen Wasser, das über die zwischen den Verbindungsstücken einander benachbarter Elemente vorhandenen Kapillarspalte in den Verriegelungskanal eindringen kann. Es kommt damit in den Verriegelungskanälen zu Wasseransammlungen, und dieses Wasser kann auf der Unterseite der Verriegelungs­kanäle ebenfalls durch die dort vorhandenen Kapillarspalte zwischen den Paßflächen der einander benachbarten Profilele­mente zur Innenseite des Daches hin austreten.Neighboring profile elements according to this state of the art each form with their lateral connecting pieces an essentially rectangular locking channel into which a band-like locking element is inserted. Capillary gaps form on the surfaces where the connecting pieces of the adjacent elements abut one another. The top wall in the locking element according to the prior art is convexly curved outwards, so that the transition point between the top wall and the associated connecting piece is lower than the remaining part of the top wall. At this transition point, water therefore collects when it rains, which can penetrate into the locking channel via the capillary gaps present between the connecting elements of adjacent elements. It this leads to water accumulation in the locking channels, and this water can also escape to the inside of the roof through the capillary gaps on the underside of the locking channels between the mating surfaces of the adjacent profile elements.

Aufgabe der Erfindung ist dementsprechend, ein Profilement nach dem Stand der Technik so auszugestalten, daß seine Stei­figkeit und damit seine Flächenbelastbarkeit erhöht wird. Dabei soll weiter die Oberwand eines solchen Profilelementes so ge­staltet werden, daß die Gefahr eines Wassereintritts in den Hohlraum, der zwischen zwei aneinandergesetzten Profilelementen gebildet wird, reduziert ist.The object of the invention is accordingly to design a profiled element according to the prior art in such a way that its rigidity and thus its surface loading capacity is increased. The top wall of such a profile element should also be designed so that the risk of water ingress into the cavity, which is formed between two profile elements placed against one another, is reduced.

Diese Aufgabe wird mit einem Ein- oder Mehrkammer-Profil­element nach dem Oberbegriff des Patentanspruches 1 gelöst, das erfindungsgemäß die in seinem Kennzeichenteil aufgeführten Merkmale aufweist.
Weitere, vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved with a single or multi-chamber profile element according to the preamble of claim 1, which according to the invention has the features listed in its characterizing part.
Further advantageous embodiments of the invention result from the subclaims.

Gemäß der Erfindung ist vorgesehen, daß die Kammeroberwand in ihrem Mittelteil entgegengesetzt gekrümmt ist zu den an den Kammerseitenwänden angrenzenden Bereichen. Dabei ist die Krüm­mung der Kammeroberwand vorzugsweise so gewählt, daß ihr tiefster Punkt von der Übergangsstelle Kammeroberwand/seitliche Endwand entfernt liegt. Insbesondere entspricht die Krümmung der Kammeroberwand einer Kosinus-Kurve. Die Kammerunterwand ist vorzugsweise spiegelsymmetrisch zur Kammeroberwand ausgebildet, so daß beim Zusammensetzen der Profilelemente nicht auf die räumliche Orientierung geachtet werden muß.According to the invention, it is provided that the chamber top wall is curved in its central part in the opposite direction to the regions adjoining the chamber side walls. The curvature of the chamber top wall is preferably selected so that its lowest point is located away from the transition point between the chamber top wall and the lateral end wall. In particular, the curvature of the chamber wall corresponds to a cosine curve. The lower chamber wall is preferably mirror-symmetrical to the upper chamber wall, so that the spatial orientation does not have to be taken into account when assembling the profile elements.

Nach einer weiteren Ausgestaltung ist zwischen der Kammer­oberwand und der Kammerunterwand eine Trennwand angeordnet. Aufgrund dieser Trennwand wird eine Konvektionsströmung zwi­schen der kalten Kammeroberwand und der warmen Kammerinnenwand verhindert, so daß die Wärmeisolationswirkung des Profil­elementes erhöht wird.According to a further embodiment, a partition is arranged between the upper chamber wall and the lower chamber wall. Because of this partition, a convection flow between the cold chamber wall and the warm chamber inner wall is prevented, so that the thermal insulation effect of the profile element is increased.

Das erfindungsgemäße Profilelement kann auch als Mehr­kammerlement ausgebildet sein, d.h. das einstückig extrudierte Profilelement weist in seitlicher Richtung mehrere nebenein­anderliegende Kammern auf. Zwischen den einzelnen Kammern sind vorzugsweise rechteckförmige Kanäle ausgebildet, in die Metall­profile eingeschoben werden können, um dadurch die Tragfähig­keit des gesamten Daches, das aus den erfindungsgemäßen Profil­ementen zusammengesetzt ist, zu erhöhen. Da ein solches Metall-­Versteifungselement eine Kältebrücke zwischen der Oberseite des Daches und der Innenseite bildet, wird zweckmäßigerweise in diesem rechteckförmigen Kanal eine Zwischenwand vorgesehen. Eine solche Zwischenwand kann in der Nahe der Kammerunterwand oder in der Nahe der Kammeroberwand oder auch bei der Unterwnd wie der Oberwand angeordnet sein, und sie unterbricht die Käl­tebrücke zwischen der Außen- und der Innenseite des Daches. Vorzugsweise wird die Zwischenwand so angeordnet, daß sie zu­sammen mit der angrenzenden Kammeroberwand bzw. Kammerunterwand einen stetigen Übergang bildet.The profile element according to the invention can also be designed as a multi-chamber element, ie the one-piece extruded profile element has a plurality of adjacent chambers in the lateral direction. Are between the individual chambers preferably rectangular channels, into which metal profiles can be inserted, thereby increasing the load-bearing capacity of the entire roof, which is composed of the profile elements according to the invention. Since such a metal stiffening element forms a cold bridge between the top of the roof and the inside, an intermediate wall is expediently provided in this rectangular channel. Such an intermediate wall can be arranged in the vicinity of the chamber lower wall or in the vicinity of the chamber upper wall or also on the lower wall and the upper wall, and it interrupts the cold bridge between the outside and the inside of the roof. The partition is preferably arranged in such a way that it forms a continuous transition together with the adjoining upper or lower wall of the chamber.

Im folgenden wird die Erfindung anhand der in den Figuren dargestellten Ausführungsbeispiele beschrieben und näher erläu­tert. Es zeigen:

  • Figur 1 ein erstes Ausführungsbeispiel für ein erfin­dungsgemäßes Einkammer-Profilelement;
  • Figur 2 ein weiteres Ausführungsbeispiel für ein erfin­dungsgemäßes Einkammer-Profilelement;
  • Figur 3 ein erstes Ausführungsbeispiel für ein erfin­dungsgemäßes Mehrkammer-Profilelement;
  • Figur 4 ein anderes Ausführungsbesispiel für ein Mehr­kammer-Profilelement nach der Erfindung;
  • Figur 5 ein weiteres Ausführungsbeispiel eines Mehrkam­mer-Profilelementes.
The invention is described and explained in more detail below with reference to the exemplary embodiments shown in the figures. Show it:
  • Figure 1 shows a first embodiment of a single-chamber profile element according to the invention;
  • Figure 2 shows a further embodiment of a single-chamber profile element according to the invention;
  • Figure 3 shows a first embodiment of a multi-chamber profile element according to the invention;
  • Figure 4 shows another embodiment of a multi-chamber profile element according to the invention;
  • Figure 5 shows another embodiment of a multi-chamber profile element.

Die Figur 1 zeigt einen Querschnitt durch ein erstes Aus­führungsbeispiel eines erfindungsgemäßen Profilelementes. Die Kammeroberwand ist wellenförmig so gekrümmt, daß ihr Mittelteil 7 nach außen konvex vorgewölbt ist, während die an die Endwände 2 angrenzenden Bereiche 6 nach außen konkav gekrümmt sind. Die Krümmung der seitlichen Bereiche ist so ausgestaltet, daß der tiefste Punkt 14 niedriger liegt als die Übergangsstelle 15 zwischen der Kammeroberwand und der seitlichen Endwand 2. Für eine besondere Steifigkeit des Profilelementes gegen eine Durchbiegung wird der Krümmungsradius für den Mittelteil 7 der Kammeroberwand 4 so gewählt, daß er kleiner oder gleich dem halben Abstand der seitlichen Endwände 1 ist. Der Mittelteil der Kammeroberwand und der Mittelteil der spiegelsymmetrisch ausgebildete Kammerunterwand wirken damit wie ein Versteifungs­rohr.Figure 1 shows a cross section through a first embodiment of a profile element according to the invention. The upper wall of the chamber is curved in a wave shape so that its central part 7 is convexly curved outwards, while the regions 6 adjoining the end walls 2 are curved concavely outwards. The curvature of the lateral areas is designed in such a way that the lowest point 14 is lower than the transition point 15 between the upper chamber wall and the lateral end wall 2. The radius of curvature for the central part 7 of the upper chamber wall 4 is chosen for a particular stiffness of the profile element against deflection that it is less than or equal to that half the distance between the side end walls 1. The middle part of the chamber top wall and the middle part of the mirror-symmetrically formed chamber bottom wall thus act like a stiffening tube.

In vertikaler Richtung ist die Kammer 3 des Profil­elementes durch eine Trennwand 9 in eine obere Kammer 3′ und eine untere Kammer 3˝ aufgeteilt. Die Trennwand 9 verhindert eine Konvektionsströmung zwischen der kalten Kammeroberwand 4 (Dachaußenseite) und der warmen Kammerinnenwand 5 (Dachinnen­seite). Das Profilelement besteht aus lichtdurchlässigem Kunst­stoff, insbesondere aus Polyvinylchlorid oder Polycarbonat.In the vertical direction, the chamber 3 of the profile element is divided by a partition 9 into an upper chamber 3 'and a lower chamber 3'. The partition 9 prevents a convection flow between the cold chamber top wall 4 (roof outside) and the warm chamber inside wall 5 (roof inside). The profile element consists of translucent plastic, in particular polyvinyl chloride or polycarbonate.

Die Figur 2 zeigt ein weiteres Ausführungsbeispiel für ein erfindungsgemäßes Einkammerprofilelement, bei dem die Kammer­oberwand 4 und die Kammerunterwand 5 invers zu dem Ausführungs­beispiel der Figur 1 verlaufen. Bei diesem Element wirkt der Mittelteil 7 der Kammeroberwand 4 wie eine Sammelrinne für Regenwasser, daß dadurch von den Übergängen 15 zwischen der Kammeroberwand und der Seitenwand 1 ferngehalten wird.FIG. 2 shows a further exemplary embodiment of a single-chamber profile element according to the invention, in which the upper chamber wall 4 and the lower chamber wall 5 run inversely to the exemplary embodiment in FIG. 1. In this element, the middle part 7 of the chamber top wall 4 acts like a collecting gutter for rainwater in that it is kept away from the transitions 15 between the chamber top wall and the side wall 1.

Die Figur 3 zeigt ein Ausführungsbeispiel für ein Mehrkam­mer-Profilelement nach der Erfindung. Mehrere Einkammer-Profile 3, 13, 23 sind zu einem Mehrkammer-Profilelement zusammenge­setzt und einstückig ausgebildet. Zwischen den einzelnen Kam­mern 3, 13, 23 sind rechteckförmige Kanäle 10 ausgebildet, in die zur Versteifung Metallprofile 11 eingeschoben werden kön­nen. Um zu verhindern, daß diese Metallprofile 11 eine Kälte­brücke zwischen der Dachaußenseite und der Dachinnenseite bil­den, sind diese Kanäle 10 von einer Zwischenwand 8 durchzogen. In der Figur 3 befindet sich diese Zwischenwand 8 direkt neben der Kammerunterwand 5, und das Versteifungselement 11 ruht auf ihr. Die Gestaltung kann jedoch auch umgekehrt sein, so daß die Zwischenwand 8 an der Kammeroberwand gebildet ist und sich das Metallprofil 11 unterhalb dieser Wand befindet. Dieser Aufbau ergibt sich, wenn die Ausführungsform nach Figur 3 auf den Kopf gestellt wird.Figure 3 shows an embodiment of a multi-chamber profile element according to the invention. Several single-chamber profiles 3, 13, 23 are assembled to form a multi-chamber profile element and are formed in one piece. Rectangular channels 10 are formed between the individual chambers 3, 13, 23, into which metal profiles 11 can be inserted for reinforcement. In order to prevent these metal profiles 11 from forming a cold bridge between the outside of the roof and the inside of the roof, these channels 10 are traversed by an intermediate wall 8. In FIG. 3, this intermediate wall 8 is located directly next to the lower chamber wall 5, and the stiffening element 11 rests on it. However, the design can also be reversed, so that the intermediate wall 8 is formed on the chamber top wall and the metal profile 11 is located below this wall. This structure results when the embodiment according to FIG. 3 is turned upside down.

Ebenso wie bei den Ausführungsformen der Figuren 1 und 2 sind die einzelnen Kammern 3, 13, 23 von Trennwänden 9 geteilt, durch die die Wärmeisolationswirkung des Profilelementes ge­steigert wird.As in the embodiments of FIGS. 1 and 2, the individual chambers 3, 13, 23 are divided by partitions 9, by means of which the thermal insulation effect of the profile element is increased.

Die Figur 4 zeigt ein weiteres Ausführungsbeispiel, das dem der Figur 3 im wesentlichen entspricht. Bei ihm ist im Unterschied zu der Ausführungsform nach Figur 3 die Zwischen­wand 8 gegenüber der Kammerunterwand nach innen versetzt, wodurch sich eine noch bessere Isolationswirkung als bei der Ausführungsform der Figur 3 ergibt.FIG. 4 shows a further exemplary embodiment which essentially corresponds to that of FIG. 3. In contrast to the embodiment according to FIG. 3, the intermediate wall 8 is offset inwards relative to the lower chamber wall, which results in an even better insulation effect than in the embodiment of FIG. 3.

Das Ausführungsbeispiel nach Figur 5 zeigt zwei aneinan­dergesetzte Mehrkammerprofilelemente, die in den Kanälen 10 an der Kammeroberwand wie auch an der Kammerunterwand solche Zwi­schenwände 8 aufweisen. Die Elemente sind symmetrisch ausge­staltet, so daß man beim Zusammenbau der Profilelemente nicht auf ihre räumliche Orientierung achten muß. Die Anschlußflan­schen der Elemente sind wie bei den Elementen nach dem Patent P 26 33 731 ausgestaltet, die Elememte werden mit den ineinandergesetzen Flanschen und der Verriegelungsschiene 16 aneinander verklammert.The exemplary embodiment according to FIG. 5 shows two multi-chamber profile elements placed one against the other, which have such intermediate walls 8 in the channels 10 on the upper chamber wall as well as on the lower chamber wall. The elements are designed symmetrically so that you do not have to pay attention to their spatial orientation when assembling the profile elements. The connecting flanges of the elements are designed as for the elements according to the patent P 26 33 731, the elements are clamped together with the nested flanges and the locking rail 16.
