Der Erfindung liegt die Aufgabe zugrunde, ein Abdichtungs- und Befestiguπgssystem für Bauelemente auf einem Schragdach, insbesondere für großflächige photovoltaische Module oder thermische Sonnenkollektoren, zur Verfugung zu stellen, das unabhängig von den Abmessungen der Dacheindeckungsplatten auch nachträglich auf einer eingelatteten Dachflache anbringbar istThe invention has for its object to provide a sealing and fastening system for components on a pitched roof, in particular for large-area photovoltaic modules or thermal solar collectors, which can also be retrofitted to a matted roof surface regardless of the dimensions of the roofing panels
Erfindungsgemaß wird die Aufgabe dadurch gelost, daß das Abdichtungs- und Befestigungssystem zumindest folgende Funktionsteile aufweist: in First- Traufπchtung auf Dachlatten anordbare Auflageelemente, Unterlagen, welche die Aufiageelemente seitlich überragen, und an den Auflageelementen montierbare Tragerelemente.According to the invention, the object is achieved in that the sealing and fastening system has at least the following functional parts: support elements which can be arranged on roof battens in ridges, documents which project laterally beyond the support elements, and support elements which can be mounted on the support elements.
Bei der Montage wird im Bereich der für die Bauelemente vorgesehenen Flache pro in einer Linie zu verlegenden Bauelementen zumindest ein sich über die Lange der Flache erstreckendes Auflageelement auf den Dachlatten befestigt. Das Auflageelement kann ein Holzbrett oder ein Profilkorper, vorzugsweise einDuring assembly, at least one support element extending over the length of the surface is fastened to the roof battens in the area of the surface provided for the components per component to be laid in a line. The support element can be a wooden board or a profiled body, preferably a
Hohlprofilkorper sein. Sofern das Auflageelement ein Holzbrett ist, wird eine dieses seitlich überragende Unterlage aufgebracht Auf die Unterlage werden die Tragerelemente aufgelegt und durch die Unterlage hindurch an den Auflageelementen befestigt. Sofern das Auflageelemeπt witterungsbeständig ist, kann die Unterlage auch unter dem Auflageelement angebracht werden. Trägerelement mit Unterlage, Trägerelement mit Auflage oder Unterlage mit Auflage oder auch alle drei Funktionselemente gemeinsam können einstückig ausgeführt sein.Be hollow profile body. If the support element is a wooden board, a support projecting laterally from this is applied to the support, the support elements are placed and through the support to the Support elements attached. If the support element is weatherproof, the support can also be attached under the support element. Carrier element with support, support element with support or support with support or all three functional elements together can be made in one piece.
Danach werden zwischen den Auflageelementen Deckelemente verlegt, die im Bereich ihrer Längsränder von den Unterlagen überdeckt werden . Deckelemente können Dacheindeckungsplatten oder spezielle Unterdeckelemente sein . Die Unterlagen können im Bereich ihrer Längsränder mit den Deckelementen dicht verbunden sein, beispielsweise durch eine klebende Verbindung.Then cover elements are laid between the support elements, which are covered by the documents in the area of their longitudinal edges. Cover elements can be roof covering panels or special lower cover elements. The documents can be tightly connected to the cover elements in the area of their longitudinal edges, for example by an adhesive connection.
Vorteilhafterweise sind an den Längsrändern der Unterlagen auf der Unterseite Stränge aus selbstklebenden Material vorgesehen, die bei Anlieferung mit einer Schutzfolie abgedeckt sind . Anschließend werden die Bauelemente auf denStrands of self-adhesive material are advantageously provided on the underside of the longitudinal edges of the documents and are covered with a protective film on delivery. Then the components on the
Trägerelementen montiert. Die Montage der Bauelemente kann in Richtung vom First zur Traufe erfolgen, wobei Deckelemente jeweils erst kurz vor Verlegung eines Bauelements eingebaut werden. Dadurch ist jeweils ein freier Zugang zur Montagestelle von der Traufe her möglich.Carrier elements mounted. The components can be installed in the direction from the ridge to the eaves, with cover elements only being installed shortly before laying a component. This allows free access to the assembly point from the eaves.
Vorteilhafterweise weist das Abdichtungs- und Befestigungssystem zwischen den Auflageelementen verlegbare Unterdeckelemente auf, die seitlich von den Unterlagen überdeckbar sind . Vorteilhafterweise sind die Unterdeckelemente im Bereich ihrer Längsränder erhöht ausgebildet, beispielsweise in Form von Aufkantuπgen oder Sicken, so daß seitlich kein Wasser austreten kann.The sealing and fastening system advantageously has lower deck elements which can be laid between the support elements and which can be covered laterally by the documents. Advantageously, the lower deck elements are raised in the area of their longitudinal edges, for example in the form of upstands or beads, so that no water can escape from the side.
Die Unterdeckelemente können ähnlich einer Kette in First-Trauf-Richtung miteinander verbunden werden, wenn ein Unterdeckelement zumindest firstseitig und traufseitig Verbindungselemente aufweist, so daß ein traufseitig folgendes Unterdeckelement mit dem firstseitig benachbarten Unterdeckelement zugfest verbiπdbar ist.The lower deck elements can be connected to one another like a chain in the first eaves direction if a lower deck element has connecting elements at least on the ridge side and on the eave side, so that a lower deck element following on the eave side can be connected to the lower deck element adjacent to the ridge side in a tensile manner.
Vorteilhafterweise sind die Verbindungselemente als Hakenfalze ausgebildet, wobei das firstseitige Verbindungselement als U-förmiger Falz am firstseitigen Rand auf der Oberseite und das traufseitige Verbindungselement als U-förmigerAdvantageously, the connecting elements are designed as hook folds, the ridge-side connecting element as a U-shaped fold on the ridge-side edge on the top and the eaves-side connecting element as a U-shaped
Falz am traufseitigen Rand auf der Unterseite ausgebildet sind . Eine Abdichtung zu firstseitig folgenden Dacheindeckungsplatten und eine einfache Befestigung der Unterdeckelemente ist möglich, wenn firstseitig zumindest ein Ankerbauteil vorgesehen ist, das unter den firstseitig benachbarten Dacheindeckungsplatten verlegbar ist und ein traufseitiges Verbiπdungselement für ein Unterdeckelement aufweist. Das Ankerbauteil leitet abfließendes Wasser sicher auf die Oberseite der Unterdeckelemente. Das Ankerbauteil überbrückt den Abstand zwischen der unteren firstseitigen Reihe der Dacheindeckungsplatten und dem obersten Unterdeckelement. Es versteht sich, daß das Ankerbauteil auch als etwas längeres oberstes Unterdeckelement ausgebildet sein kann.Fold on the eaves-side edge are formed on the underside. A seal to the roof covering panels following on the ridge side and a simple fastening of the lower deck elements is possible if at least one anchor component is provided on the ridge side, which can be laid under the roof covering panels adjacent to the ridge side and has an eaves-side connecting element for a lower roof panel. The anchor component safely directs water to the top of the lower deck elements. The anchor component bridges the distance between the lower row of roof covering plates on the ridge side and the uppermost lower deck element. It is understood that the anchor component can also be designed as a somewhat longer top lower deck element.
Infolge der kettengliedartigen Ausbildung der Unterdeckelemente kann durch Verschieben zum First hin ein Unterdeckelement ausgehängt werden, so daß insbesondere an photovoltaischen Bauelementen deren Unterseite für Wartungs- oder Reparatur-Arbeiten zugänglich ist.As a result of the chain link-like design of the lower deck elements, a lower deck element can be unhooked by shifting towards the ridge, so that the underside of the photovoltaic components is accessible for maintenance or repair work.
Eine Abdichtung zu traufseitig folgenden Dacheindeckungsplatten wird erreicht, wenn zumindest ein traufseitiger Anschlußstreifen vorgesehen ist, der unter den Unterlagen und gegebenenfalls unter den Unterdeckelemeπten sowie über den traufseitig folgenden Dacheindeckungsplatten verlegbar ist. Zur Abstützung des traufseitigen Anschlußstreifens kann ein Stützbrett parallel zu den Dachlatten vorgesehen werden.Sealing to the eaves-side roofing panels is achieved if at least one eaves-side connecting strip is provided, which can be laid under the documents and, if necessary, under the under-cover elements and over the eaves-side roofing panels. A support board can be provided parallel to the roof battens to support the eaves-side connecting strip.
Eine besonders dichte Abdichtung zu traufseitig folgenden Dacheindeckungsplatten ist möglich, wenn der traufseitige Anschlußstreifen an die Kontur der traufseitig folgenden Dacheindeckungsplatten anformbar ist. Hierzu eignet sich ein zumindest in Längsrichtung streckbares Material, das an seinem traufseitigen Rand auf der Unterseite einen Strang aus selbstklebendem Material aufweist.A particularly tight seal to the roof covering panels following on the eaves side is possible if the eaves-side connecting strip can be molded onto the contour of the roof covering panels following on the eaves side. A material that is stretchable at least in the longitudinal direction and has a strand of self-adhesive material on the underside of its eaves side is suitable for this.
Die Trägerelemente können mit Befestigungselementen wie Schrauben oder Nägeln in einfacher Weise an dem Auflageelement über der Unterlage befestigt werden, wenn eine Unterlage aus einem elastomeren Werkstoff wie Polyisobutylen besteht, so daß die Unterlage sie durchsetzende Befestigungselemente der Trägerelemente abdichtet.The carrier elements can be fastened with fastening elements such as screws or nails to the support element above the base in a simple manner if a base consists of an elastomeric material such as polyisobutylene, so that the base seals fastening elements of the carrier elements which penetrate them.
Vom First her auf dem Dach ablaufende Flüssigkeit wird sicher auf die Oberseite der Bauelemente geleitet, wenn ein firstseitiger Anschlußstreifen vorgesehen ist, der unter den firstseitig benachbarten Dacheindeckungsplatten und auf dem firstseitigen Randabschπitt eines oder mehrerer nebeneinanderliegeπder Bauelemente verlegbar ist.Liquid running from the ridge on the roof is safely conducted to the top of the components if a ridge-side connecting strip is provided is which can be laid under the roof covering panels adjacent to the ridge side and on the ridge side edge section of one or more components lying next to one another.
Auf die Unterseite eines Trägerelements gelangte Flüssigkeit wird abgeführt und kann verdunsten, wenn das Trägerelement im Querschnitt ein offenes Profil aufweist.Liquid that has reached the underside of a carrier element is drained off and can evaporate if the carrier element has an open profile in cross section.
Vorteilhafterweise ist das Trägerelement im Querschnitt als hutförmiges Profil ausgebildet.The cross section of the carrier element is advantageously designed as a hat-shaped profile.
