Description

Die Erfindung betrifft einen Bausatz nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a kit according to the preamble of claim 1.

Aus der DE 34 21 107 A ist ein aus Modulelementen aufgebautes Giebeldach bekannt. Dieses weist zu beiden Seiten des Firstes anordbare plattenförmige Bauteile auf, welche die Dachfläche bilden. Ein Bauteil weist zumindest eine Deckplatte auf, an deren Unterseite in First-Trauf-Richtung verlaufende Sparren angeordnet sind. Die Sparren zweier einander gegenüberliegender Bauteile sind im Bereich ihrer firstseitigen Enden gelenkig miteinander verbunden, so daß sich eine zusammenklappbare Dachkonstruktion ergibt.DE 34 21 107 A discloses a gable roof made up of modular elements. This has plate-shaped components that can be arranged on both sides of the ridge which form the roof area. One component has at least one cover plate, rafters are arranged on the underside of the rafters. The Rafters of two opposing components are in the area of their ridge-side Ends hinged together so that there is a collapsible Roof construction results.

Aus der EP 0 103 333 ist ein aus Plattenelementen aufgebautes Giebeldach bekannt. Dieses weist zu beiden Seiten des Firstes anordbare plattenförmige Bauteile auf, welche die Dachfläche bilden. In einem Bauteil kann ein Durchbruch für ein Dachfenster vorgesehen sein. Ein Bauteil weist zumindest eine Deckplatte auf, an deren Unterseite eine parallel zum First bzw. zur Traufe verlaufende Pfette angeordnet ist. An beiden Stirnenden wird eine Pfette jeweils in einer U-förmigen Stütze aufgenommen, die an einer in First-Traufrichtung verlaufenden Leiste befestigt ist. Die Leisten sind an den Giebelwänden bzw. an Sparren befestigt.EP 0 103 333 discloses a gable roof constructed from plate elements. This has plate-shaped components which can be arranged on both sides of the ridge, which form the roof area. A breakthrough for a roof window can be made in a component be provided. A component has at least one cover plate, on the underside thereof a purlin running parallel to the ridge or eaves is arranged. At both A purlin is received in each end in a U-shaped support, the is attached to a strip running in the eaves direction. The lasts are on attached to the gable walls or rafters.

Nachteilig an den bekannten Ausführungen ist die Tatsache, daß sämtliche Bauteile in Länge und Breite speziell für das jeweilige Dach hergestellt werden müssen.A disadvantage of the known designs is the fact that all components in length and width have to be manufactured specifically for the respective roof.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Bausatz zu schaffen, bei dem nur wenige Bauteile an die tatsächliche Länge und Breite des Dachs angepasst werden müssen. The invention is therefore based on the object of creating a kit which only a few components are adapted to the actual length and width of the roof Need to become.

Diese Aufgabe wird gemäß den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved in accordance with the features of patent claim 1.

Während die Länge der Tragteile und gegebenenfalls des Traufdeckteils und/oder des Firstdeckteils der Länge des Daches anzupassen ist, muß nur zumindest eines der Randtragteile in seiner Breite werkseitig so angefertigt werden, daß die Randtragteile in auf dem Dach eingebautem Zustand einen Abstand voneinander aufweisen, der einem Rastermaß entspricht. Vorzugsweise werden beide Randtragteile in gleicher Breite angefertigt. Da heute viele Häuser in Fertigbauweise erstellt werden, sind die Abmessungen der Gebäude vereinheitlicht. Aufgrund dieser Gegebenheiten sind auch die Längen der Dächer und somit die Längen der Tragteile und der Deckteile relativ einheitlich. Auch können unwesentliche Differenzen durch unterschiedliche Dachüberstände ausgeglichen werden.During the length of the supporting parts and possibly the eaves cover part and / or the Ridge deck part is to be adapted to the length of the roof, only at least one of the Edge support parts in width are made in the factory so that the edge support parts have a distance from each other when installed on the roof, the corresponds to a grid dimension. Preferably, both edge support parts are the same Width made. As many prefabricated houses are built today, they are Unified building dimensions. Because of these conditions, too the lengths of the roofs and thus the lengths of the supporting parts and the cover parts relative uniformly. Insignificant differences can also be caused by different roof overhangs be balanced.

Um bei einem Dach, dessen Breite größer als die Breite eines Seriendeckteils zuzüglich der Breite zweier Randtragteile ist, die Breite der Öffnung auf die einheitliche Breite der Deckteile von vorzugsweise 3,60 m zu reduzieren, können zusätzlich Serientragteile mit einer einheitlichen Breite vorgesehen werden. Vorzugsweise ist die Breite eines Serientragteils gleich einem ganzzahligen Bruchteil der Breite eines Seriendeckteils. Serientragteile sind vorzugsweise 6 m lang und 1,20 m breit. Dadurch ergibt sich ein Rastermaß für die Breite der Fläche zwischen den Randtragteilen von 1,20 m, wobei durch weitere Serientragteile von beispielsweise 90 cm und von 60 cm Breite ein noch engeres Rastermaß von 30 cm erzielt werden kann. Es versteht sich, daß bei passender Breite des Daches auch Serientragteile als Randtragteile eingesetzt werden können.In order for a roof whose width is greater than the width of a standard roof panel plus is the width of two edge support parts, the width of the opening to the uniform Width of Can reduce deck parts of preferably 3.60 m additional standard support parts with a uniform width be provided. Preferably the width is one Series support part equal to an integer fraction of the width of a series cover part. Standard load-bearing parts are preferably 6 m long and 1.20 m wide. This results in a grid dimension for the width of the area between the edge support parts of 1.20 m, whereby by further series support parts of, for example, 90 cm and 60 cm wide, an even narrower grid size of 30 cm can be achieved. It goes without saying that when fitting Width of the roof also standard support parts as edge support parts can be used.

Die Länge der freien Fläche zwischen den Tragteilen wird durch die Differenz zwischen deren Länge und der Summe der Längen von Traufdeckteil, Firstdeckteil und Seriendeckteil bzw. Seriendeckteilen bestimmt. Um gegebenenfalls eine verbleibende Lücke zu schließen, kann ein Ausgleichsdeckteil mit der einheitlichen Breite des Rastermaßes und individuell angepaßter Länge vorgesehen werden.The length of the free area between the supporting parts is determined by the difference between their length and the sum of the lengths of eaves cover part, ridge cover part and series cover part or Series cover parts determined. To possibly a remaining one To close the gap, a compensating cover part with the uniform width of the grid size and individual adapted length can be provided.

Somit sind lediglich die Randtragteile in ihrer Breite und das Ausgleichsdeckteil in seiner Länge auf die individuellen Abmessungen des Daches abzustimmen, während die übrigen Bauteile in hoher Stückzahl mit einheitlichen Abmessungen hergestellt werden können. Es versteht sich, daß die Breite des Traufdeckteils, des Firstdeckteils, des Ausgleichsdeckteils und des Seriendeckteils stets gleich ist. Ein bevorzugtes Seriendeckteil ist 1,20 m lang und 3,60 m breit. Es versteht sich, daß in First-Trauf-Richtung mehrere Seriendeckteile aneinandergefügt werden können, und daß ein Seriendeckteil auch als Traufdeckteil oder als Firstdeckteil verwendet werden kann.Thus, only the edge support parts in their width and that Compensating cover part in its length to the individual Adjust dimensions of the roof while the rest Large quantities of components with uniform dimensions can be produced. It is understood that the width the eaves cover part, the ridge cover part, the Compensating cover part and the series cover part is always the same. A preferred series cover is 1.20 m long and 3.60 m wide. It is understood that in the first eaves direction several Series cover parts can be joined together, and that a Standard cover part also as eaves cover part or as ridge cover part can be used.

Dies bietet fertigungstechnisch den Vorteil, daß Serientragteile, Firstdeckteile, Traufdeckteile und Seriendeckteile serienmäßig in hoher Stückzahl mit einheitlichen Abmessungen hergestellt werden können. Die Verbindung der Deckteile mit den Tragteilen bzw. dieser untereinander kann beispielsweise durch Verschraubung erfolgen.This offers the advantage in terms of production technology that Standard support parts, ridge cover parts, eaves cover parts and Standard cover parts in large quantities with uniform dimensions can be produced. The Connection of the cover parts with the supporting parts or this with each other, for example, by screwing respectively.

Ein Tragteil weist zumindest einen in First-Trauf-Richtung verlaufenden Träger auf, der dem Tragteil eine hohe Biegesteifigkeit verleiht. Der Träger kann beispielsweise aus Stahl bestehen und als Fachwerkträger oder als I-Profil mit Durchbrüchen im Steg zur Gewichtsersparnis ausgeführt sein. Um das ästhetische Bild der Tragteile nicht zu beeinträchtigen, kann der Träger gekammert sein.A supporting part has at least one in the first eaves direction trending carrier, the support part a high Flexural rigidity gives. The carrier can for example be made of Steel exist and as a truss or as an I-profile Breakthroughs in the web to save weight. Around not to impair the aesthetic appearance of the supporting parts, the carrier can be chambered.

Die Deckteile sind selbsttragend ausgebildet und werden von den Tragteilen abgestützt. Die Deckteile können ähnlich wie die Tragteile Träger aufweisen, die in diesem Fall parallel zur Traufe bzw. zum First verlaufen und die Ausführung von sehr breiten selbsttragenden Deckteilen ermöglichen.The cover parts are self-supporting and are from supported the supporting parts. The deck parts can be similar to the supporting parts have carriers, which in this case are parallel to the eaves or to the ridge and the execution of enable very wide self-supporting cover parts.

Die Anordnung von Trägern, welche die Trag- bzw. Deckteile nicht überragen, ermöglicht eine glatte Ausbildung der dem Dachinnenraum zugewandten Fläche der Dachunterkonstruktion. Dadurch ergibt sich eine niedrige Höhe der Bauteile und somit ein zusätzlicher Raumgewinn.The arrangement of beams, which the support or cover parts not towering, enables a smooth formation of the Area of the roof substructure facing the interior of the roof. This results in a low component height and thus an additional gain in space.

Ein wesentliches Merkmal der Erfindung besteht darin, daß der Bausatz in First-Trauf-Richtung verlegbare Tragteile, welche freitragend ausgebildet sind und die Last des Daches auf Pfetten übertragen, und an den Tragteilen befestigte selbsttragende Deckteile aufweist. Es versteht sich, daß bei einem sehr breiten Dach mit mehr als einem Abschnitt mit Seriendeckteilen zwischen diesen jeweils zumindest ein Serientragteil vorzusehen ist.An essential feature of the invention is that the kit in Support elements that can be laid in the first eaves direction, which are self-supporting are trained and the load of the roof on purlins transferred, and self-supporting attached to the supporting parts Has cover parts. It goes without saying that with a very wide roof with more than one section with standard cover parts between these at least one series support part is to be provided.

Die Stoßkanten der Bauteile können stumpf aneinanderstoßend, mit einem Stufenfalz mit Vorsprung/Rücksprung oder mit einer Nut-Feder-Verbindung ausgeführt werden. Zwischen den Bauteilen ist eine Dichtung vorgesehen, insbesondere im Bereich der Oberseiten der Bauteile eine luft- und regendichte Dichtung. The abutting edges of the components can be butted together, with a step fold with projection / recess or with one Tongue-and-groove connection. Between the components a seal is provided, particularly in the area of An airtight and rainproof seal on the top of the components.

Die Dichtung kann beispielsweise als separater elastischer Dichtungsstreifen, vorzugsweise aus Neopren oder dergleichen, oder als auf die Stoßflächen der Bauteile aufgebrachte Beschichtung aus dauerelastischem Material ausgeführt sein.The seal can, for example, as a separate elastic Sealing strips, preferably made of neoprene or the like, or as applied to the abutting surfaces of the components Coating made of permanently elastic material.

Um einen den individuellen Wünschen des Bauherrn entsprechenden Ausbau des Dachraumes zu ermöglichen, kann das Seriendeckteil mit einem Dachsystemteil versehen sein, beispielsweise mit einer Dachgaube, einem Dachfenster, einem Schornsteindurchlaß, einem Lüftungselement, einem Solarmodul oder dergleichen. Aufgrund der Vereinheitlichung ist es auch möglich, ein anfangs eingebautes Seriendeckteil nachträglich gegen ein anderes Seriendeckteil mit einem speziellen Dachsystemteil auszutauschen. Beispielsweise kann bei einem späteren Ausbau des Dachraumes ein geschlossenes Seriendeckteil gegen ein solches mit einem Dachfenster oder mit einer Dachgaube ausgetauscht werden.To meet the client's individual wishes to enable appropriate expansion of the roof space Series cover part be provided with a roof system part, for example with a dormer window, a skylight, a Chimney outlet, a ventilation element, a solar module or similar. Because of the standardization it is too possible, a built-in series cover part at a later date against another series cover with a special Replace roof system part. For example, with a later expansion of the attic a closed Series cover part against such with a skylight or can be replaced with a dormer window.

Die Verwendung von zwei Ausgleichsdeckteilen bietet den Vorteil, daß mit Hilfe dieser die Position des Seriendeckteils zwischen Traufe und First verändert werden kann, um beispielsweise eine Dachgaube entsprechend der Dachneigung und den Bauvorschriften in der vorgeschriebenen Brüstungshöhe einbauen zu können. Ein Deckteil mit einem Dachfenster, einem Schornsteindurchlaß oder einem Lüftungselement kann schmaler als ein Seriendeckteil ausgeführt sein, beispielsweise in halber Breite, und es können seitlich Sonderpaßdeckteile vorgesehen werden, um insbesondere die Position eines Schornsteindurchlasses der Lage des Schornsteins im Gebäude exakt anzupassen.The use of two compensating cover parts offers the Advantage that with the help of this the position of the series cover part between eaves and ridge can be changed to for example a dormer according to the roof pitch and the building regulations in the prescribed parapet height to be able to install. A cover with a skylight, one Chimney opening or a ventilation element can be narrower be designed as a series cover part, for example in half width, and there may be special fitting cover parts on the side be provided in particular the position of a Chimney outlet of the position of the chimney in the building to adapt exactly.

Die Bauteile des Bausatzes können monolithisch aus einem gießbaren Werkstoff wie Beton hergestellt sein. Eine sehr leichte Ausführung der Bauteile ergibt sich, wenn sie aus einem geopolymeren Werkstoff, aus Leichtbeton oder aus Schaumbeton hergestellt sind. The components of the kit can be monolithic from one castable material such as concrete. A very easy execution of the components results when they are made a geopolymer material, made of lightweight concrete or Foam concrete are made.

Um eine besonders gute Schall- und Wärmedämmung zu erreichen, können die plattenförmigen Bauteile des Bausatzes sandwichartig ausgeführt sein mit Deckschichten und einer dazwischenliegenden Schall- und/oder Wärmedämmschicht. Als Deckschicht können beispielsweise Span- oder Leichtbetonplatten verwendet werden. Zur Schalldämmung kann beispielsweise Mineralwolle und zur Wärmedämmung kann Mineralwolle und/oder Polyurethanschaum vorgesehen sein. Um den Ausbau des Dachinnenraums zu erleichtern, kann die dem Dachinnenraum zugewandte Deckschicht bereits werkseitig konfektioniert sein, beispielsweise durch einen Anstrich, eine Beschichtung oder eine Verkleidung.In order to achieve particularly good sound and heat insulation, can the plate-shaped components of the kit be sandwiched with facings and one intermediate sound and / or thermal insulation layer. As Top layer can for example chipboard or Lightweight concrete slabs are used. Can be used for sound insulation for example mineral wool and for thermal insulation Mineral wool and / or polyurethane foam can be provided. Around to facilitate the expansion of the roof interior Cover layer facing the roof interior already at the factory be made up, for example by a coat of paint Coating or cladding.

Eine paßgenaue Montage des Bausatzes wird erreicht, wenn er in weiterer Ausgestaltung der Erfindung außerdem zumindest ein im Traufbereich verlegbares Fußpfettenteil aufweist, auf dem die Tragteile traufseitig abstützbar sind.A precisely fitting assembly of the kit is achieved if it is in Another embodiment of the invention also at least one in Eaves area that can be laid on the purlin part on which the Supporting parts can be supported on the eaves side.

Die Tragteile können an ihren firstseitigen Enden scharnierartig miteinander verbünden sein, so daß es ausreicht, wenn für ein Satteldach zwei Fußpfettenteile verlegt werden.The supporting parts can at their first-sided ends be hinged together so that it is sufficient if two parts of the purlin for a gable roof be relocated.

Bei unverbundenen Tragteilen ist es vorteilhaft, wenn der Bausatz zusätzlich zumindest ein im Firstbereich parallel zum First verlegbares Firstpfettenteil aufweist, an dem die plattenförmigen Tragteile firstseitig befestigbar sind. Im zuletzt genannten Fall können die Tragteile an ihren firstseitigen Enden auf Gehrung zugeschnitten sein, so daß sie im Firstbereich stumpf aneinanderstoßen. Andernfalls kann im Firstbereich ein im Querschnitt keilförmiges Firstelement verlegt werden, das die Tragteile miteinander verbindet und den dazwischen bestehenden Spalt abdichtet. Das Firstelement kann gleichzeitig eine Abstützung für aufzulegende Firstpfannen bilden. Die Anzahl und Anordnung der Pfettenteile des Bausatzes ist generell nicht beschränkt und hängt von der Form des Daches ab. So kann beispielsweise der Bausatz für ein zusammengesetztes Pultdach vier oder mehr Pfettenteile aufweisen.With unconnected supporting parts, it is advantageous if the Kit additionally at least one in the ridge area parallel to the Has ridge purlin part that can be installed, on which the plate-shaped supporting parts can be fastened on the ridge side. in the the latter case, the supporting parts on their ridge-side ends to be mitred so that they butt in the ridge area. Otherwise, in Ridge area is a ridge element that is wedge-shaped in cross section be laid that connects the supporting parts with each other and seals the gap between them. The ridge element can also be a support for on-hook Form ridge pans. The number and arrangement of the purlin parts the kit is generally not limited and depends on the Shape of the roof. For example, the kit for a Compound pent roof four or more purlin parts exhibit.

Die Pfettenteile des Bausatzes können massiv ausgeführt sein, beispielsweise aus Stahl, Beton, Holz oder Verbundwerkstoff. Eine sehr leichte und dennoch stabile Ausführung ergibt sich, wenn ein Pfettenteil als Hohlprofil ausgebildet ist. Diese Ausbildung bietet den zusätzlichen Vorteil, daß Leitungen für Strom, Gas, Wasser, Abgas oder dergleichen innerhalb der Pfettenteile verlegt werden können.The purlin parts of the kit can be solid, for example made of steel, concrete, wood or composite material. A very light, yet stable design results if a purlin part is designed as a hollow profile. This Training offers the additional advantage that lines for Electricity, gas, water, exhaust gas or the like within the Purlin parts can be laid.

Die Pfettenteile können im Querschnitt unterschiedlich ausgebildet sein. So kann ein im Firstbereich zu verlegendes Firstpfettenteil beispielsweise einen dreieckigen der Dachneigung entsprechenden Querschnitt aufweisen. Vorteilhafterweise ist der Querschnitt der Pfettenteile jedoch rund, so daß die in First-Trauf-Richtung verlegten Tragteile bei verschiedenen Dachneigungen stets tangential an die Pfettenteile anlegbar sind. Ein derartiges Pfettenteil kann beispielsweise rohrförmig ausgebildet sein und Lochreihen mit in Umfangsrichtung verlaufenden Langlöchern aufweisen. Ein Tragteil kann rechtwinklig von seiner Innenfläche ausgehende Verbindungselemente, beispielsweise Schraubbolzen, aufweisen, die in die Langlöcher des Pfettenteils einbringbar sind, so daß eine Verschraubung des Tragteils mit dem Pfettenteil möglich ist.The purlin parts can have different cross sections be trained. So can be installed in the ridge area Ridge purlin part, for example, a triangular one Have the appropriate cross-section of the roof pitch. However, the cross section of the purlin parts is advantageous round, so that the supporting parts are laid in the first eaves direction with different roof pitches always tangent to the Purlin parts can be put on. Such a purlin part can for example, be tubular and have rows of holes have elongated holes extending in the circumferential direction. On The supporting part can extend at right angles from its inner surface Have connecting elements, for example screw bolts, which can be introduced into the elongated holes of the purlin part, so that a screw connection of the support part to the purlin part is possible.

Die Auflage auf dem Pfettenteil erfolgt vorzugsweise unter Zwischenlage von Distanzelementen, so daß First- und Traufdeckteil nicht auf dem Pfettenteil aufliegen, sondern ausschließlich über die Tragteile abgestützt werden. Das Distanzelement kann eine an das plattenförmige Bauteil anlegbare plane Oberseite und eine der Krümmung des Pfettenteils entsprechend konkav geformte Unterseite aufweisen.The rest on the purlin part is preferably under Intermediate layer of spacer elements, so that ridge and Eaves cover part do not rest on the purlin part, but are supported only on the supporting parts. The Spacer can be attached to the plate-shaped component attachable flat top and one of the curvature of the Part of the purlin correspondingly concave underside exhibit.

Die Montage der gesamten Dachunterkonstruktion ab Oberkante des obersten Geschosses ist möglich, wenn der Bausatz in weiterer Ausgestaltung der Erfindung Giebelteile aufweist, die entsprechend dem Querschnittsprofil des herzustellenden Daches geformt sind. Für ein einfaches Satteldach kann das Giebelteil beispielsweise als in der Vorderansicht dreieckiges den Giebel bildendes Fertigteil ausgeführt sein. Um den Transport eines schweren und großformatigen Giebelteils zu erleichtern, kann das Giebelteil aus einzelnen Segmenten zusammenfügbar sein. Das Giebelteil kann bereits mit Fenstern, beispielsweise mit einem großflächigen dreieckigen Giebelfenster, versehen sein. Je nach Anordnung und Anzahl der Fenster kann das Giebelteil fachwerkartig ausgebildet sein. Das Giebelteil kann beispielsweise auch so geformt sein, daß es das Querschnittsprofil für ein zusammengesetztes Pultdach oder ein Mansarddach vorgibt.Installation of the entire roof substructure from the top edge of the top floor is possible if the kit is in a further embodiment of the invention has gable parts which according to the cross-sectional profile of the roof to be manufactured are shaped. The gable part can be used for a simple gable roof For example, as the front view triangular the gable precast element. To transport a heavy and large-sized gable part the gable part can be assembled from individual segments. The gable part can already have windows, for example with a large triangular gable window. Depending on the arrangement and number of windows, the gable part can be designed like a truss. The gable part can for example, be shaped so that it Cross-sectional profile for a composite pent roof or a Mansard roof pretends.

Für ein einfaches Walmdach kann der Bausatz ein in der Vorderansicht dreieckiges Walmgiebelteil aufweisen, das an seiner Unterseite der Walmneigung entsprechend angeschrägt ist, so daß eine plane Auflage auf die Decke bzw. auf die giebelseitige Wand des Gebäudes möglich ist. Da ein Walmdach in der Draufsicht zwischen der vom Firstende ausgehenden Fallinie, der Traufe und dem Grat eine dreieckige Randfläche aufweist, ist es vorteilhaft, wenn im Bausatz dreieckige erste Paßdeckteile vorgesehen sind, welche jeweils die Fläche zwischen Randtragteil und Walmgiebelteil ausfüllen. In diesem Fall wird das rechteckige Randtragteil ausgehend vom Anfallpunkt des Daches montiert.For a simple hipped roof, the kit can be installed in the Front view of triangular hip gable part that have bevelled accordingly on its underside to the hip inclination is, so that a flat support on the ceiling or on the gable wall of the building is possible. There is a hipped roof in the top view between the one starting from the ridge end Fall line, the eaves and the ridge a triangular edge has, it is advantageous if triangular first in the kit Fitting cover parts are provided, each covering the surface Fill between the edge support part and the hip gable part. In this Case, the rectangular edge support part is based on Fitting point of the roof mounted.

Für ein Krüppelwalmdach kann der Bausatz ein in der Vorderansicht etwa dreieckiges mit einer schräg zum First hin abgewinkelten Spitze ausgeführtes Krüppelwalmgiebelteil und trapezförmige zweite Paßdeckteile aufweisen, welche jeweils die Fläche zwischen Randtragteil und Krüppelwalmgiebelteil ausfüllen, denn auch in diesem Fall wird das rechteckige Randtragteil ausgehend vom Anfallpunkt des Daches montiert.The kit can be used for a half-hipped roof Front view roughly triangular with a sloping towards the ridge angled tip made of crippled whale gable part and have trapezoidal second fitting cover parts, each the area between the edge support part and the crippled whale gable part fill in, because in this case too, the rectangular Edge support part mounted starting from the point of attack of the roof.

Eine Belastung des Bauwerks im Bereich der Fußpfettenteile sowie durch Abstützungen des Firstpfettenteils wird vermieden, wenn in besonders vorteilhafter Ausgestaltung der Erfindung die Pfettenteile freitragend ausgebildet und an ihren Enden mit den Giebelteilen verbindbar sind, so daß diese die gesamte Last des Daches auf das Gebäude übertragen.A load on the structure in the area of the purlin parts as well as by supporting the ridge purlin part, if in a particularly advantageous embodiment of the invention the purlin parts are self-supporting and at their ends are connectable to the gable parts so that they cover the entire Load of the roof transferred to the building.

Bei der Montage, beispielsweise auf dem Rohbau von Reihenhäusern mit quer zur Trennwand verlaufendem First, können die Giebelteile auf die Trennwände der einzelnen Reihenhäuser aufgesetzt werden, so daß das Aufmauern des Giebels entfällt. Ähnlich ist es bei der Sanierung von Altbauten, denn die Trennwände zwischen benachbarten Gebäuden sind als Brandschutzwände meistens stärker ausgebildet als die traufseitigen Wände. Die Giebelteile können jeweils mit Ankern oder Winkeln befestigt werden und anschließend durch die Pfettenteile ausgesteift werden.During assembly, for example on the shell of Row houses with ridges running across the partition, can the gable parts on the partitions of each Row houses are placed so that the building of the Gable does not apply. It is similar with the renovation of Old buildings, because the partitions between neighboring buildings are usually designed as fire protection walls stronger than that Eaves walls. The gable parts can each with anchors or angles and then through the Purlin parts are stiffened.

Ein Fußpfettenteil ist in diesem Fall so ausgebildet, daß es die aus der Abstützung der Tragteile resultierende in Richtung zur Traufe wirkende Kraftkomponente als Querkraft aufzunehmen vermag. Über die Verbindung des Fußpfettenteils mit dem Giebelteil werden die Kräfte auf das betreffende Giebelteil übertragen. Hierbei wird die der Gewichtskraft des Daches entsprechende vertikale Kraftkomponente über die Giebelteile in die Giebelwände geleitet, so daß die traufseitigen Wände des Gebäudes frei von Belastungen durch das Dach bleiben. Daher kann traufseitig auf eine tragende Wand des Gebäudes verzichtet werden, und es kann beispielsweise eine Glasfassade vorgesehen werden. Die horizontalen Kraftkomponenten werden ebenfalls von den Giebelteilen aufgenommen, so daß keine Zuganker erforderlich sind.In this case, a purlin part is designed so that it the direction resulting from the support of the supporting parts Force component acting on the eaves as shear force can. About the connection of the purlin part with the Gables are the forces on the gable in question transfer. This is the weight of the roof corresponding vertical force component over the gable parts led into the gable walls, so that the eaves-side walls of the building remain free of loads from the roof. Therefore, the eaves side can be on a load-bearing wall of the building can be dispensed with, and for example a glass facade be provided. The horizontal force components are also taken from the gable parts, so that none Tie rods are required.

Zur Befestigung der Pfettenteile kann ein Giebelteil von seinen Rändern beabstandete Aufnahmen für die Enden der Pfettenteile aufweisen. Die Ausbildung einer Aufnahme bietet in zweierlei Hinsicht Vorteile. Erstens kann ein Drehmoment um die Längsachse des Pfettenteils aufgenommen werden, das infolge der nicht mittig als Querkraft in das Pfettenteil eingeleiteten in Trauf-Richtung wirkenden Kraftkomponente entsteht. Zweitens kann durch die Aufnahmen stets eine paßgenaue Verbindung zwischen Giebelteil und Pfettenteil erreicht werden. Die Übertragung der Kräfte kann beispielsweise durch Formschluß erfolgen, indem die Geometrie der Aufnahme an den Querschnitt des Pfettenteils angepaßt ist. Der Abstand der Aufnahmen zu den Rändern der Giebelteile gewährleistet, daß die im Traufbereich verlegten Fußpfettenteile stets oberhalb der Geschoßdecke des Gebäudes schweben und keine Kräfte auf diese übertragen. Nur bei einem sehr breiten Dach ist eine zusätzliche Abstützung etwa in der Mitte der Pfettenteile erforderlich. Bei einem schmalen Dach kann im Bereich des Traufdeckteils auf das Fußpfettenteil verzichtet werden, so daß ein Giebelteil lediglich im Bereich eines Tragteils einen Abschnitt eines Fußpfettenteils aufweist. In diesem Fall ist der Abschnitt des Fußpfettenteils vorzugsweise als kurzer freitragender Tragarm ausgebildet, der biegesteif mit dem Giebelteil zu verbinden ist.A gable part from its edges spaced receptacles for the ends of the Have purlin parts. The training of a recording offers advantages in two ways. First, torque can be around the longitudinal axis of the purlin part are included as a result of not being centered as a transverse force in the purlin part initiated force component acting in the eaves direction arises. Second, the recordings can always be one precise connection between the gable section and the purlin section can be achieved. The transfer of forces can for example, by form fit, by the geometry the recording is adapted to the cross section of the purlin part. The distance of the recordings to the edges of the gable parts ensures that those laid in the eaves area Parts of the purlin always above the floor of the building hover and transfer no forces to it. Only one very wide roof is an additional support approximately in the Middle of the purlin parts required. With a narrow roof can in the area of the eaves cover part on the purlin part be dispensed with, so that a gable part only in the area of a support part a section of a purlin part having. In this case, the section of the purlin part preferably designed as a short self-supporting arm, the is rigidly connected to the gable part.

Eine Aufnahme kann beispielsweise als Durchbruch, Vertiefung oder als auf die Innenfläche des Giebelteils aufgesetzter Beschlag ausgebildet sein. Ein Beschlag kann beispielsweise mit einem Flansch am Giebelteil anbringbar sein und eine rechtwinklig zum Flansch bzw. zum Giebelteil angeordnete Halbschale zur Aufnahme des Pfettenteils aufweisen. Die Halbschale und das Pfettenteil können beispielsweise durch Bolzen miteinander verbindbar sein, so daß die Dachunterkonstruktion beim Aufbau möglichst schnell aussteifbar ist. Es versteht sich, daß am Giebelteil auch ein von seiner Innenfläche ausgehender angeformter Vorsprung als Aufnahme vorgesehen sein kann.A recording can, for example, as a breakthrough, deepening or as placed on the inner surface of the gable part Fitting be formed. A fitting can for example be attachable with a flange on the gable part and a arranged at right angles to the flange or to the gable part Have a half-shell to hold the purlin part. The Half-shell and the purlin part can be, for example Bolts can be connected so that the Roof substructure as quickly as possible during construction is stiffenable. It is understood that on the gable part also molded projection proceeding from its inner surface as Recording can be provided.

Die plattenförmigen Bauteile des Bausatzes können bereits werkseitig auf ihrer Oberseite mit Dachlatten versehen sein, so daß sie sofort nach der Montage mit Dachpfannen eingedeckt werden können.The plate-shaped components of the kit can already factory-fitted with roof battens on the top, so that they are covered with roof tiles immediately after assembly can be.

Die plattenförmigen Bauteile können ohne Dachlatten eingedeckt werden, wenn sie auf der Oberseite mit parallel zum First verlaufenden Vorsprüngen versehen sind, die in üblichen Dachlattenabständen voneinander angeordnet sind.The plate-shaped components can be covered without roof battens if they are on top with parallel to the ridge extending projections are provided in the usual Roof slat distances are arranged from each other.

Das aufwendige Eindecken mit Dachpfannen kann entfallen, ohne daß auf das ansprechende äußere Erscheinungsbild einer derartigen Deckung verzichtet werden muß, wenn die plattenförmigen Bauteile auf ihrer Oberseite entsprechend der Form von Dachpfannen profiliert sind.The elaborate roofing with roof tiles can be omitted without that on the appealing external appearance of a such cover must be waived if the plate-shaped components on their top according to the Form of roof tiles are profiled.

Die plattenförmigen Bauteile können auf ihrer Oberseite auch mit Dachbahnmaterial versehen sein, wobei die Abdeckung bereits werkseitig erfolgen kann. Als Dachbahnmaterial kommen vorzugsweise für die Abdichtung von Flachdächern bewährte Erzeugnisse in Frage.The plate-shaped components can also on their top be provided with roofing material, the cover can already be done at the factory. Come as roofing membrane material tried and tested, preferably for sealing flat roofs Products in question.

Eine rasche und regensichere Montage der Dachunterkonstruktion ist möglich, wenn Tragteile und Traufdeckteile im Bereich ihres traufseitigen Randes mit einer Dachrinne versehen sind. Bei der Montage sind lediglich die einzelnen Abschnitte der Dachrinne dichtend miteinander zu verbinden. Eine besonders einfache Konstruktion ergibt sich, wenn der traufseitige Rand der Tragteile und Traufdeckteile nach oben hin abgewinkelt ist, so daß nach der Montage in die dadurch gebildete Rinne lediglich ein über die gesamte Breite der Traufe verlaufender Streifen aus Dachbahnmaterial einzulegen ist.A quick and rainproof installation of the roof substructure is possible if supporting parts and eaves cover parts are in the area their eaves-side edge are provided with a gutter. During assembly, only the individual sections of the Connect the gutter to each other in a sealing manner. A special one simple construction results when the eaves-side edge of the supporting parts and eaves cover parts angled upwards is, so that after assembly in the groove formed by it only one that runs across the entire width of the eaves Strips of roofing membrane material must be inserted.

In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel der Erfindung dargestellt, das im folgendem näher erläutert wird.In the drawing, a preferred embodiment of the Invention shown, which is explained in more detail below.
