Description

Die Erfindung betrifft ein Befestigungssystem für eine Dachabdeckung oder Wandverkleidung, die aus selbsttragenden, im Querschnitt U-förmigen Elementen besteht, die parallel nebeneinander gelegt mit an ihren hochstehenden Schenkeln durch Auswärtsbiegen angeformten und unterschiedlich dicken Wulsträndern ineinandergreifen und durch zwischen jeweils benachbarten Elementen bis in die ineinandergreifenden Wulstränder sich hinein erstreckende Halter abgestützt sind, die aus Profilträgerabschnitten bestehen und in der Breite eines Elementes entsprechenden gegenseitigen Abständen auf quer zur Längsrichtung der Elemente angeordneten Trägern befestigt sind, wobei unter jedem Halter eine Isolierunterlage angeordnet ist.The invention relates to a fastening system for a roof covering or wall cladding, which consists of self-supporting, cross-sectionally U-shaped elements which are placed in parallel side by side with bead edges formed on their upstanding legs by bending outwards and interlocking and interlocking between adjacent elements Bead edges extending into brackets are supported, which consist of profiled sections and are fixed in the width of an element corresponding mutual spacing on brackets arranged transversely to the longitudinal direction of the elements, wherein an insulating pad is arranged under each holder.

Ein derartiges Befestigungssystem ist aus US-A-4 337 606 bekannt.Such a fastening system is known from US-A-4 337 606.

Bei einer Dachabdeckung bezeichnet man diese Träger als Pfetten, auf denen das Gewicht der Dachabdeckung ruht. Das Gewicht wird über die Halterübertragen, die als Profilträgerabschnitte beispielsweise im Querschnitt T-förmig ausgebildet sind, wobei das auf dem Kopf stehende T-Profil mit dem hochstehenden Steg sich zwischen benachbarten Dachabdeckungs-Elementen bis in die ineinandergreifenden Wulstränder dieser Elemente hineinerstreckt. Diese aus Metall bestehenden Halter bilden Kältebrücken zwischen der Aussenseite und der Innenseite der Dachabdeckung, während statt dessen eine Isolierung zwischen den Trägern und der Vielzahl von Haltern, die die Verbindung zu den ebenfalls aus Metall bestehenden Dachabdeckungs- Elementen herstellen, bauphysikalisch wesentlich vorteilhafter wäre. Die erwähnte metallische Verbindung zwischen der Innenseite und der Aussenseite überträgt auch den Schall, sodass auch in dieser Hinsicht eine fehlende Isolierung einen Mangel darstellt.In the case of a roof covering, these beams are called purlins on which the weight of the roof covering rests. The weight is transferred via the holder, which is designed as a profile support section, for example in cross section T-shaped, the upside-down T-profile with the upstanding web extending between adjacent roof covering elements into the interlocking bead edges of these elements. These metal brackets form thermal bridges between the outside and the inside of the roof covering, while instead insulation between the brackets and the large number of brackets that connect to the roof covering elements, which are also made of metal, would be significantly more advantageous in terms of building physics. The aforementioned metallic connection between the inside and the outside also transmits the sound, so that a lack of insulation is also a defect in this regard.

Bei der Montage werden die im Querschnitt U-förmigen und mit den Wulsträndern an den hochstehenden Schenkeln übereinandergreifenden Dachabdeckungs- oder Wandelemente auf den Haltern abgestützt, welche in der Breite eines Elementes entsprechenden Abständen voneinander, d.h. in konstanten Abständen, auf dem auch als Pfette bezeichneten Träger zu befestigen sind. Die Abstände der Befestigungsstellen auf dem Träger müssen vorher auf diesem ausgemessen und gekennzeichnet werden.During assembly, the roofing or wall elements, which are U-shaped in cross-section and overlap with the bead edges on the upstanding legs, are supported on the brackets, which are spaced from one another by the width of an element, i.e. at constant intervals, to be fastened on the support, also known as a purlin. The distances between the mounting points on the beam must be measured and marked on the beam beforehand.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, zwischen den Haltern, auf denen die Dachabdeckungs- oder Wandverkleidungs-Elemente aufliegen und den jeweils zur Abstützung einer Vielzahl von Haltern dienenden Trägern eine Wärme- und Schallisolierung vorzusehen und gleichzeitig mit dieser Massnahme eine wesentliche Vereinfachung der Montagearbeit in der Weise zu erreichen, dass die Abstände zwischen den auf jedem der Träger zu befestigenden Haltern nicht mehr ausgemessen zu werden brauchen. Die Lösung dieser Aufgabe erfolgt gemäss den Merkmalen nach Anspruch 1. Bevorzugte Ausführungsformen ergeben sich aus den abhängigen Ansprüchen.The present invention was therefore based on the object to provide heat and sound insulation between the brackets on which the roof covering or wall cladding elements lie and the brackets serving in each case to support a plurality of brackets, and at the same time this measure considerably simplifies the assembly work in such a way that the distances between the holders to be fastened on each of the supports no longer need to be measured. This object is achieved according to the features of claim 1. Preferred embodiments result from the dependent claims.

Bei einer bevorzugten Ausführungsform ist ein bandförmiges vorzugsweise aufrollbares Material in konstanten Abständen voneinander mit einzelnen Isolierunterlagen verbunden. Als Befestigungsart kann eine Klebverbindung oder eine Befestigung durch Hineinschlagen von an den Isolierunterlagen vorgesehenen spitzen Vorsprüngen in das bandförmige Material vorgesehen sein. Der Vorteil dieser Methode besteht darin, dass man erst auf der Baustelle ein Isolierunterlagenband mit den geforderten Abständen zwischen den Isolierunterlagen erstellt und dabei für das die Trägerfunktion übernehmende Band ein preisgünstigeres minderwertigeres Material verwendet, auf dem die aus einem hochwertigeren Kunststoffmaterial bestehenden Isolierunterlagen befestigt werden, wobei dieses Material temperaturbeständig, alterungsbeständig und elektrisch nicht leitfähig sein muss. Statt eines bandförmigen Trägermaterials könnten auch zwei parallele Schnüre mit einzelnen Isolierunterlagen verbunden werden. Jede Isolierunterlage weist oberseitig eine Montagefläche in der Grösse des Fussteils eines Halters auf, sodass bei Anordnung je eines Halters auf der Montagefläche jeder der einzelnen lsolierunterlagen die Abstände der Halter richtig eingehalten sind.In a preferred embodiment, a band-shaped, preferably rollable material is connected at constant intervals from one another with individual insulating pads. An adhesive connection or a fastening by hammering in pointed projections provided on the insulating pads into the band-shaped material can be provided as the type of fastening. The advantage of this method is that an insulating pad tape with the required spacing between the insulating pads is only created on the construction site and a cheaper, lower-quality material is used for the tape taking over the carrier function, on which the insulating pads made of a higher-quality plastic material are attached, whereby this material must be temperature-resistant, aging-resistant and not electrically conductive. Instead of a band-shaped carrier material, two parallel cords could also be connected with individual insulation pads. Each insulating pad has a mounting surface the size of the foot part of a holder on the top side, so that when a holder is arranged on the mounting surface of each of the individual insulating pads, the distances between the holders are correctly maintained.

Bei einer weiteren bevorzugten Ausführungsform sind eine Vielzahl von Isolierunterlagen und das sie verbindende Material einstückig ausgebildet, sodass ein sich längs erstreckendes streifenförmiges Material vorliegt, in dem die für die Anordnung eines Halters vorgesehenen Montageflächen in bestimmter Weise markiert sind. Dies kann in Gestalt einer Vertiefung in der Grösse des Fussteils des Halters ausgeführt sein, oder auch in Gestalt einer Erhöhung, d.h. dass das Materialband Bereiche mit erhöhter Materialstärke aufweist. Ferner können die Stellen zur Plazierung eines Halters auch durch Anschläge markiert sein, beispielsweise in Form von leistenförmigen quer über das streifenförmige Material sich erstreckenden Erhöhungen, gegen welche der Fussteil eines Halters anzulegen ist. Statt einer Leiste können auch nur einzelne hochstehende Noppen die Anschläge bilden. Schliesslich können auch die Anschlagleisten in Kombination mit aufgrund erhöhter Materialstärke höherliegenden Montageflächen kombiniert werden. Ebenso ist es möglich, ein aufrollbares streifenförmiges Material von konstanter Materialstärke in Abständen voneinander mit vorbereiteten Klebeflächen für die Anordnung je eines Halters zu versehen oder nur mit gestanzten Löchern zu versehen, durch die hindurch die Halter auf dem Träger festgeschraubt werden.In a further preferred embodiment, a multiplicity of insulating underlays and the material connecting them are formed in one piece, so that there is a longitudinally extending strip-shaped material in which the mounting surfaces provided for the arrangement of a holder are marked in a certain way. This can be in the form of a recess in the size of the foot part of the holder, or also in the form of an elevation, ie the material band has areas with increased material thickness. Furthermore, the places for placing a holder can also be marked by stops, for example in the form of strip-shaped elevations extending transversely over the strip-shaped material, against which the foot part of a holder is to be placed. Instead of a bar, only single upstanding knobs can form the stops. Finally, the stop bars can also be combined in combination with mounting surfaces that are higher due to the increased material thickness. It is also possible to provide a roll-up strip-shaped material of constant material thickness at intervals from one another with prepared adhesive surfaces for the arrangement of one holder each, or to provide only punched holes through which the holder on the Carrier screwed.

In Fig. 1 ist das Prinzip einer Dachabdeckung dargestellt, bei der bekannte, im Querschnitt U-förmige Dachabdeckungselemente 1, die in Wirklichkeit eine über viele Meter, vorzugsweise über das gesamte Dach sich erstreckende Länge aufweisen, parallel nebeneinander angeordnet sind und die an ihren hochstehenden Schenkeln 2 angeformten, an den beiden Schenkeln unterschiedlich dicken Wulstränder 3 und 4 übereinander greifen, wodurch jeweils benachbarte Dachabdeckungselemente 1 miteinander verbunden sind. Die Dachabdeckungselemente 1 sind auf Haltern 5 abgestützt, die Abschnitte von T-Profilträgern sind, von denen der hochstehende Schenkel 6 sich zwischen benachbarten Dachabdeckungselementen 1 in die übereinandergreifenden Wulstränder 3 und 4 hinein erstreckt. Der zum Schenkel 6 rechtwinklige Fussteil 7 jedes Halters 5 ruht auf einem quer zur Längsrichtung der Elemente 1 sich erstreckenden Träger 8, von denen eine Mehrzahl in Abständen voneinander als Pfetten die Dachkonstruktion tragen. Auf diesen Trägern 8 müssen die Halter 5 in konstanten Abständen voneinander, die der Breite eines Dachabdeckungselementes 1 entsprechen, montiert werden und dabei soll gleichzeitig eine Wärmedämmung und Schallisolierung zwischen dem Träger 8 und den Haltern 5 erreicht werden. Zu diesem Zweck ist in Fig. 1 auf der Oberfläche des Trägers 8 zwischen diesem und den Fussteilen 7 der Halter 5 ein streifenförmiges Material 9 mit Isoliereigenschaften angeordnet, das dem Ausführungsbeispiel gemäss Fig. 6 entspricht. Dieses streifenförmige Material oder Band 9 besitzt von seiner Oberfläche vorstehende, querverlaufende Anschlagleisten 10, gegen die jeweils der Fussteil 7 eines Halters 5 angelegt wird, wodurch eine korrekte Abstandseinhaltung zwischen den einzelnen Haltern 5 bei der Montage erreicht wird, ohne dass diese Abstände abgemessen zu werden brauchen.In Fig. 1, the principle of a roof covering is shown, in which known, in cross-section U-shaped roof covering elements 1, which in reality have a length extending over many meters, preferably over the entire roof, are arranged in parallel next to each other and which stand up at them Legs 2 integrally formed, on the two legs of different thickness bead edges 3 and 4 engage one above the other, whereby adjacent roof covering elements 1 are connected to each other. The roof covering elements 1 are supported on holders 5, which are sections of T-profile beams, of which the upstanding leg 6 extends between adjacent roof covering elements 1 into the overlapping bead edges 3 and 4. The foot part 7 of each holder 5, which is at right angles to the leg 6, rests on a support 8 which extends transversely to the longitudinal direction of the elements 1, of which a plurality bear the roof structure at a distance from one another as purlins. The holders 5 must be mounted on these supports 8 at constant distances from one another, which correspond to the width of a roof covering element 1, and at the same time thermal insulation and sound insulation between the supports 8 and the holders 5 are to be achieved. For this purpose, a strip-shaped material 9 with insulating properties, which corresponds to the exemplary embodiment according to FIG. 6, is arranged on the surface of the carrier 8 between the latter and the foot parts 7 of the holder 5. This strip-shaped material or band 9 has transverse stop strips 10 protruding from its surface, against which the foot part 7 of a holder 5 is placed, whereby correct spacing between the individual holders 5 is achieved during assembly without these distances being measured need.

Der mit der Erfindung verfolgte Zweck wird erreicht, wenn unter jedem Halter 5 eine Isolierunterlage vorhanden ist und diese in gleichmässigen Abständen aneinandergereiht sind.The purpose pursued by the invention is achieved when an insulating pad is present under each holder 5 and these are strung together at regular intervals.

In Fig. 2 ist eine einfache Ausführungsform dieser Art dargestellt, bei der an einem bandförmigen, aufrollbaren Material 15 in konstanten Abständen voneinander Isolierunterlagen 16 befestigt sind. Der Vorteil dieser Ausführungsform besteht darin, dass ein preiswertes Bandmaterial verwendet werden kann, an welchem die Isolierunterlagen 16 aus hochwertigerem Kunststoffmaterial, das die gewünschten Eigenschaften für die Wärmedämmung und Schallisolierung aufweist, befestigt werden. Ein weiterer Vorteil besteht darin, dass der konstante Abstand zwischen den Isolierunterlagen 16 kleiner oder grösser gemacht werden kann, wenn Dachabdeckungselemente 1 einer geringeren oder einer grösseren Breite verlegt werden sollen. Das bandförmige Material 15 mit den lsolierunterlagen 16 kann auf der Baustelle hergestellt werden, sodass je nach Bedarf die Isolierunterlagen 16 in kleinerem oder grösserem Abstand voneinander befestigt werden. Dazu benötigt man nur eine einfache zeichnerisch nicht dargestellte Abstandslehre und möglichst einfache Methode für die Befestigung, wofür es zahllose Möglichkeiten gibt. In Fig. 3a - c sind drei Beispiele aus den vorhandenen Möglichkeiten dargestellt. Die Isolierunterlage 16 gemäss Fig. 3a weist einen Schlitz 17 für das bandförmige Material 15 auf und die Seite oberhalb des Schlitzes weist an drei Seiten aus dem Kunststoffmaterial herausgeschnittene Lappen 18 auf, die zwecks Befestigung nach unten in das bandförmige Material, das in Fig. 3a nicht dargestellt ist, hineingeschlagen werden. Bei der Ausführungsform gemäss Fig. 3b ist nur ein an drei Seiten herausgeschnittener Lappen 19, der unterseitig zugespitzt ist, vorhanden, der zwecks Befestigung nach unten in das bandförmige Material hineinzuschlagen ist. Die lsolierunterlage gemäss Fig. 3c ist dank einer flexiblen Zone in der Mitte ganz aufklappbar und trägt innenseitig spitze Vorsprünge 20, die beim Zusammenklappen dieser Isolierunterlage um das bandförmige Material 15 herum sich in dieses hineindrücken.FIG. 2 shows a simple embodiment of this type, in which insulating pads 16 are fastened to a band-shaped, rollable material 15 at constant intervals from one another. The advantage of this embodiment is that an inexpensive strip material can be used, to which the insulating pads 16 made of higher-quality plastic material, which have the desired properties for thermal insulation and sound insulation, are attached. Another advantage is that the constant distance between the insulating pads 16 can be made smaller or larger if roof covering elements 1 of a smaller or a larger width are to be laid. The band-shaped material 15 with the insulating underlays 16 can be produced on the construction site, so that the insulating underlays 16 are fastened at a smaller or greater distance from one another as required. All you need is a simple distance gauge, not shown in the drawing, and the simplest possible method for fastening, for which there are countless possibilities. 3a-c show three examples from the available options. The insulating pad 16 according to FIG. 3a has a slot 17 for the band-shaped material 15 and the side above the slot has tabs 18 cut out of the plastic material on three sides, which for the purpose of fastening down into the band-shaped material shown in FIG. 3a is not shown. In the embodiment according to FIG. 3b there is only one tab 19 cut out on three sides and tapered on the underside, which is to be hammered down into the band-shaped material for the purpose of fastening. The insulating base according to FIG. 3c can be opened completely thanks to a flexible zone in the middle and has pointed projections 20 on the inside, which in the case of Collapse this insulating pad around the band-shaped material 15 and press it into it.

Für die Anordnung der Isolierunterlagen 16 in bestimmten Abständen voneinander können jedoch auch statt des bandförmigen Materials zwei parallele Schnüre verwendet werden. Neben dieser die erwähnten Vorteile aufweisenden Ausführungsform gibt es zahlreiche Möglichkeiten für eine einstückige Ausführungsform, bei der die Isolierunterlagen und das zwecks Aneinanderreihung diese verbindene Material einstückig ausgebildet sind und vorzugsweise aus einem geeigenten Kunststoffmaterial bestehen.For the arrangement of the insulating pads 16 at certain distances from each other, two parallel cords can be used instead of the band-shaped material. In addition to this embodiment having the advantages mentioned, there are numerous possibilities for a one-piece embodiment in which the insulating pads and the material connecting them for the purpose of stringing them together are formed in one piece and preferably consist of a suitable plastic material.

Bei der in Fig. 4 dargestellten Ausführungsform weist ein streifenförmiges und aufrollbares Isoliermaterial 21 mit selbstklebenden Haftmitteln versehene, quer verlaufende Abschnitte 22 in der Grösse des Fussteils eines Halters auf, wobei die konstanten Abstände zwischen diesen Abschnitten 22 der Breite eines Dachabdeckungs-oder Wandverkleidungselementes 1 entsprechen.In the embodiment shown in FIG. 4, a strip-shaped and rollable insulating material 21 provided with self-adhesive adhesives has transverse sections 22 the size of the foot part of a holder, the constant distances between these sections 22 corresponding to the width of a roof covering or wall covering element 1 .

Die gleiche Ausgestaltung zeigt die Ausführungsform gemäss Fig. 5, bei der die mit Haftmittel versehenen Abschnitte 22 an einem dickeren streifenförmigen Material 23 angeordnet sind, das nicht oder nur beschränkt aufrollbar ist.The same embodiment is shown in the embodiment according to FIG. 5, in which the sections 22 provided with adhesive are arranged on a thicker strip-shaped material 23 which cannot be rolled up or can only be rolled up to a limited extent.

Die Ausführungsform gemäss Fig. 6 ist der in Fig. 1 dargestellte Isoliermaterialstreifen 9 mit querverlaufenden Anschlagleisten 10, die für die Einhaltung der Abstände zwischen den Haltern bestimmt sind. Statt der einen Leiste 10 können gemäss Fig. 7 auch zwei parallele Leisten 10 und 11 vorgesehen sein, zwischen die der Fussteil 7 eines Halters 5 anzuordnen ist. Ferner können bei der Ausführungsform gemäss Fig. 8 auch nur je auf einer Querlinie angeordnete vorgestanzte Löcher 12 vorhanden sein, durch die hindurch die Halter 5 auf dem streifenförmigen Isoliermaterial 9 in den richtigen Abständen voneinander mittels bis in den Träger sich hineinerstreckender Schrauben, vorzugsweise Selbstbohrschrauben, befestigt werden.The embodiment according to FIG. 6 is the insulating material strip 9 shown in FIG. 1 with transverse stop strips 10, which are intended for maintaining the distances between the holders. Instead of one strip 10, two parallel strips 10 and 11 can also be provided, according to FIG. 7, between which the foot part 7 of a holder 5 is to be arranged. Furthermore, in the embodiment according to FIG. 8 there can also be only pre-punched holes 12 arranged on a transverse line, through which the holders 5 on the strip-shaped insulating material 9 are spaced at the correct distances from one another by means of screws, preferably self-drilling screws, which extend into the carrier. be attached.

Bei den Ausführungsformen gemäss Fig. 9 und Fig. 10 sind in einem Materialstreifen 25 in Abständen voneinander querverlaufende Abschnitte 26 mit verminderter Materialstärke ausgebildet. Diese bilden jeweils einen Rezess, in welchen ein Halter 5 für die Abstützung der Dachabdeckungselemente eingesetzt wird. Bei der Ausführungsform gemäss Fig. 9 sind diese Abschnitte 26 an der Oberseite des Materialstreifens 25 ausgebildet, während bei der Ausführungsform gemäss Fig. 10 die Abschnitte 26 an der Oberseite wie auch an der Unterseite ausgebildet sind, wobei man zweckmässig das Abstandsmass zwischen diesen Abschnitten 26 an der Oberseite anders wählt als an der Unterseite, sodass ein solcher Materialstreifen 25 für zwei verschiedene Bedarfsfälle bezüglich der Breite der Dachabdeckungselemente verwendet werden kann.In the embodiments according to FIGS. 9 and 10, sections 26 with reduced material thickness are formed in a material strip 25 at intervals from one another. These each form a recess in which a holder 5 is used to support the roof covering elements. In the embodiment according to FIG. 9, these sections 26 are formed on the upper side of the material strip 25, while in the embodiment according to FIG. 10 the sections 26 are formed on the upper side as well as on the underside, the spacing between these sections 26 expediently being used selects differently on the top than on the bottom, so that such a material strip 25 can be used for two different needs with regard to the width of the roof covering elements.

Bei den Ausführungsformen gemäss Fig. 11 und Fig. 12 weist der Materialstreifen 27 in gleichen Abständen voneinander querverlaufende Abschnitte 28 mit erhöhter Materialstärke auf, die somit einen Sockel für die Anordnung je eines Halters 5 bilden. Bei der Ausführungsform gemäss Fig. 12 besitzt der Sockel 28 noch zusätzlich Begrenzungsleisten 29, zwischen die der Halter 5 einzusetzen ist.In the embodiments according to FIGS. 11 and 12, the material strip 27 has sections 28 of increased material thickness which run transversely from one another at equal intervals and which thus form a base for the arrangement of one holder 5 each. In the embodiment according to FIG. 12, the base 28 also has additional limiting strips 29, between which the holder 5 is to be inserted.

Bei den Ausführungsformen gemäss Fig. 13 und Fig. 14 besitzt ein Materialstreifen 30 an einer Längskante gemäss Fig. 13 oder an beiden Längskanten gemäss Fig. 14 ein hochstehendes Bord 31 mit einer Hohlkehle 32. In dem Bord 31 sind in Abständen voneinander Schlitze 33 ausgebildet, in die jeweils ein Halter 5 mit seinem hochstehenden Steg 6 hineingeschoben wird, wobei der Fussteil 7 des Halters 5 in die Hohlkehle 32 eingreift.In the embodiments according to FIGS. 13 and 14, a material strip 30 has a raised rim 31 with a groove 32 on one longitudinal edge according to FIG. 13 or on both longitudinal edges according to FIG. 14. Slots 33 are formed at intervals in the rim 31 , into each of which a holder 5 with its upstanding web 6 is inserted, the foot part 7 of the holder 5 engaging in the groove 32.

Es versteht sich, dass noch weitere Ausführungsvarianten möglich sind, mit denen das Ziel erreicht wird, gleichzeitig mit der Verlegung einer Isoliermaterialschicht zwischen einem Träger und den darauf anzuordnenden Haltern die richtigen Abstände zwischen den Haltern zu markieren.It goes without saying that still further design variants are possible with which the goal is achieved to mark the correct distances between the holders simultaneously with the laying of an insulating material layer between a carrier and the holders to be arranged thereon.

Da die Träger aus Stahl und die Halter vorzugsweise aus Aluminium bestehen, würden sich ohne das zwischen diesen angeordnete Isoliermaterial verschiedene Spannungspotentiale ergeben, so dass bei Anwesenheit von Feuchtigkeit ein Strom fliessen kann und dadurch bezüglich der Träger und der Halter das eine Material das andere Material zerstören würde, weshalb das Isoliermaterial neben den vorgenannten Funktionen zusätzlich auch die wichtige Funktion hat, Schäden dieser Art zu verhindern.Since the supports are made of steel and the holders are preferably made of aluminum, different voltage potentials would result without the insulating material arranged between them, so that a current can flow in the presence of moisture and thus one material destroy the other material with respect to the supports and the holders would, which is why the insulating material also has the important function of preventing such damage in addition to the aforementioned functions.
