Description

Die Erfindung bezieht sich auf einen Fertigteildachbaukasten für Bauwerke, welcher eine Mehrzahl von modularen, selbsttragenden Einzelelementen enthält sowie auf modulare Elemente für einen derartigen Fertigteildachbaukasten.The invention relates to a prefabricated roof box for buildings, which contains a plurality of modular, self-supporting individual elements as well as modular elements for such a prefabricated roof box.

Aus der FR 2414597 A sind selbsttragende Dachelemente bekannt geworden, welche einen zargenartigen Rahmen mit einer Abdeckplatte aufweisen. Im Prinzip handelt es sich hier um einen Baukasten zur Errichtung eines Dachstuhles, bei welchem die einzelnen Elemente zusammengesteckt werden und durch die Verbindung mit benachbarten Elementen zu einer tragenden Dachkonstruktion verbunden werden, die an entsprechenden Trägern wiederum abgestützt werden kann. Die sich insgesamt nach dem Zusammenbau der einzelnen untereinander verschiedenen Dachelemente ergebende Dachfläche kann in der Folge mit einer Dacheindeckung ausgestattet werden, wobei beispielsweise zunächst Leisten an den selbsttragenden Dachelementen festgelegt werden, welche eine Dacheindeckung aus Dachziegeln ermöglichen. Die bekannte Ausbildung setzte zum einen eine große Anzahl verschiedener Elemente voraus und war zum anderen nur durch nachträgliches Eindecken entsprechend als Witterungsschutz geeignet und abgedeckt. Eine unmittelbare Herstellung eines Daches durch Kombination einer geringen Anzahl modularer Einzelelemente ist mit den bekannten Lösungen nicht möglich.From FR 2414597 A self-supporting roof elements have become known which have a frame-like frame with a cover plate. In principle, this is a construction kit for the construction of a roof truss, in which the individual elements are plugged together and connected by the connection with adjacent elements to a supporting roof structure, which in turn can be supported on corresponding carriers. The total resulting after assembly of the individual mutually different roof elements roof surface can be equipped with a roofing in the sequence, for example, first strips are fixed to the self-supporting roof elements, which allow roofing of roof tiles. The known training firstly required a large number of different elements and was suitable and covered only by subsequent covering accordingly as weather protection. A direct production of a roof by combining a small number of modular individual elements is not possible with the known solutions.

Die Erfindung zielt nun darauf ab, einen Fertigteildachbaukasten der eingangs genannten Art zu schaffen, bei welchem mit einem Minimum an voneinander verschiedenen Elementen unmittelbar mit der Verlegung der Elemente auch eine Dacheindeckung ermöglicht wird und mit einer geringen Anzahl voneinander verschiedener Elemente eine große Anzahl von verschiedenen Dachformen und an unterschiedliche Grundrisse angepassten Dachformen ermöglicht wird.The invention now aims to provide a finished product roof box of the type mentioned, in which with a minimum of different elements directly with the laying of the elements also a roofing is possible and with a small number of different elements a large number of different roof shapes and adapted to different layouts roof shapes is made possible.

Zur Lösung dieser Aufgabe besteht der erfindungsgemäße Fertigteildachbaukasten im Wesentlichen darin, dass jedes modulare Einzelelement ein Tragelement mit Anschlussstellen für benachbarte Trageelemente sowie eine mit dem Trageelement verbundene oder einstückig mit diesem ausgebildete Dachhaut aufweist und dass jedes modulare Element in der Vertikalprojektion einen rechteckigen, insbesondere quadratischen, Grundriss aufweist, dessen Grundrissform modular mit in der Vertikalprojektion gleichen Maßen für eine definierte Dachneigung vorliegt. Dadurch, dass die Modularität einheitlich beibehalten wird und Elemente zum Einsatz gelangen, welche in der Vertikalprojektion jeweils gleichen Grundriss aufweisen, wird ein System geschaffen, bei welchem die Tragelemente gemeinsam mit der jeweils mit den Tragelementen verbundenen oder einstückig mit diesen ausgebildeten Dachhaut so zusammengebaut werden können, dass die Dachhaut eines modularen Einzelelementes die Dachhaut eines benachbarten modularen Einzelelementes in der Falllinie und damit in der Abtropflinie übergreift, sodass unmittelbar eine entsprechend dichte Konstruktion gewährleistet ist. Die Verwendung einer einheitlichen modularen Grundrissform und Grundrissabmessung erlaubt es die Anzahl von verschiedenen modularen Einzelelementen für die Eindeckung unterschiedlicher Grundrisse auf ein Minimum zu reduzieren, wobei insbesondere für eine definierte Dachneigung mit nur drei von einander verschiedenen modularen Elementen das Auslangen gefunden werden kann.To solve this task, the prefabricated roof box according to the invention consists essentially in the fact that each modular Single element has a support element with connection points for adjacent support elements and connected to the support member or integrally formed with this roof skin and that each modular element in the vertical projection has a rectangular, in particular square, floor plan whose floor plan form modular with the same dimensions in the vertical projection for a defined Roof pitch is present. The fact that the modularity is uniformly maintained and elements are used, which in each case have the same plan in the vertical projection, a system is provided in which the support elements can be assembled together with each associated with the support elements or integrally formed with these roof skin in that the roof skin of a modular individual element overlaps the roof skin of an adjacent modular individual element in the fall line and thus in the drop line, so that a correspondingly dense construction is ensured immediately. The use of a uniform modular floor plan and floor plan allows to reduce the number of different modular single elements for the coverage of different layouts to a minimum, in particular for a defined roof pitch with only three mutually different modular elements Auslangen can be found.

In besonders vorteilhafter Weise ist der Fertigteildachbaukasten hierbei so weitergebildet, dass wenigstens drei voneinander verschiedene modulare Einzelelementtypen im Baukasten vorhanden sind, wobei neben einen quadratischen Grundriss aufweisenden Elementen mit ebener Dachhaut ein zweiter modularer Elementtyp mit sich über eine Diagonale des Elementes erstreckendem Grat oder konvexer Krümmung sowie ein dritter modularer Elementtyp mit sich über eine Diagonale erstreckender Senke bzw. konkaver Krümmung zur Ausbildung einer Ichse vorgesehen ist. Die im Wesentlichen quadratischen Grundrissformen werden somit einheitlich für einfache Dachelemente und Dachgratelemente beibehalten, wobei dann, wenn von einem quadratischen oder rechteckigen Grundriss des Gebäudes abweichende Dachkonstruktionen realisiert werden sollen, zusätzlich auch noch modulare Elemente zur Ausbildung einer Ichse vorgesehen sein müssen. Auch hier wird für die Ichsenelemente die Modularität beibehalten um in der Folge den Anschluss der modular gleichen, und insbesondere auf gleichen Grundriss in der Vertikalprojektion und gleiche Dachneigung ausgelegte Standardeinzelelemente zu gewährleisten. Die Ichsenelemente sollen aber gleichzeitig sicherstellen, dass Regenwasser ohne Behinderung abgeleitet wird, und es ist aus diesem Grund für Ichsenelemente vorgesehen, diese mit im wesentlichen L-förmiger Draufsicht aus drei Elementen mit im Wesentlichen gleichem quadratischen Grundriss in der Vertikalprojektion zusammenzusetzen bzw. einstückig mit der L-Form auszubilden und in dieser vorgefertigten Form einzusetzen. Dies hat den Vorteil, dass an den Anschlussstellen des mittleren der drei modularen Grundelemente an die seitlich angeschlossenen Standardelemente eine ebene Abdichtung in der Dachhautebene vorgenommen werden kann, sodass Regenwasser ungehindert abfließen kann. Bevorzugt ist die Ausbildung hierbei so getroffen, dass das Ichsenelement in der Vertikalprojektion eine Fläche aufweist, welche einem ungeradzahligen Vielfachen der Fläche eines modularen Einzelelements mit ebener oder grat-förmiger Dachhaut entspricht und in der Draufsicht eine L-Form ergibt.In a particularly advantageous manner, the prefabricated roof box here is further developed so that at least three different modular single element types are available in the kit, in addition to a square plan having elements with a flat roof skin, a second modular element type with extending over a diagonal of the element ridge or convex curvature and a third modular element type is provided with a diagonally extending depression or concave curvature for forming an ego. The substantially square plan shapes are thus uniform for maintain simple roof elements and roof ridge elements, in which case, if different from a square or rectangular floor plan of the building roof structures are to be realized, in addition, even modular elements must be provided to form an ego. Again, the modularity is maintained for the Isen elements in order to ensure the connection of the modular same, and in particular on the same floor plan in the vertical projection and the same roof pitch designed standard individual elements. The Ichsenelemente but at the same time to ensure that rainwater is discharged without hindrance, and it is for this reason provided for Ichsenelemente to assemble them with a substantially L-shaped plan view of three elements with substantially the same square plan in the vertical projection or integral with the Form L-shape and use in this prefabricated form. This has the advantage that at the junctions of the middle of the three modular base elements to the laterally connected standard elements a level seal in the roof skin level can be made so that rainwater can flow freely. Preferably, the training is in this case made such that the Ichsen element in the vertical projection has a surface which corresponds to an odd multiple of the surface of a modular single element with a flat or burr-shaped roof skin and in plan view results in an L-shape.

In den Fällen der Verbindung von modularen Elementen, welche quer zur Falllinie der Dachhaut links und rechts von der Dachhaut mit einem Element verbunden werden, müssen gesonderte Dichtleisten angeordnet werden, um das gewünschte Maß an Witterungsbeständigkeit, Resistenz und Dichtheit sicher zu gewährleisten.In the cases of the connection of modular elements, which are connected transversely to the fall line of the roof skin left and right of the roof skin with an element, separate sealing strips must be arranged to ensure the desired level of weather resistance, resistance and tightness safely.

Modulare Elemente für einen Fertigteildachbaukasten der eingangs genannten Art sind erfindungsgemäß zargenförmig ausgebildet und weisen an ihren Seitenflächen Anschlussstellen für Verbinder zweier benachbarter Tragelemente auf. Die Seitenflächen können auch mit Zugbändern armiert ausgebildet sein. Eine derartige Konstruktion ermöglicht die Verwendung besonders leichter Werkstoffe, da die erforderliche Stabilität durch die an den Seitenflächen angeordneten Zugbänder gewährleistet wird. Die Zugbänder können dabei auch die für die sichere Verbindung der modularen Elemente erforderlichen Lasten aufnehmen und dies auch dann, wenn für die Zargen- bzw. die Rahmenkonstruktion des Tragelementes leicht und statisch weniger belastbare Baumaterialien eingesetzt werden. Eine Belastung der Tragelemente in Längsrichtung der Zugbänder wird insbesondere dann vermieden, wenn die gegenseitige Verbindung der Zugbänder benachbarter Tragelemente derart erfolgt, dass die Tragelemente selbst einander nicht berühren, d.h. in Abstand voneinander angeordnet sind. Eine derartige Verbindung benachbarter Tragelemente lässt sich mit einheitlich gestalteten Verbindern bevorzugt dann verwirklichen, wenn, wie es einer erfindungsgemäßen Weiterbildung entspricht, die Ausbildung so getroffen ist, dass jeweils zwei zueinander parallel verlaufende Zugbänder an den Seitenflächen der Zargen festgelegt sind, welche mit der Dachoberkante einen spitzen Winkel einschließen. Dadurch, dass die Zugbänder nicht parallel zur Dachoberkante bzw. zur Ebene der Dachhaut angeordnet sind, können einfache und besonders stabile Verbinder mit kreuzförmigem Querschnitt eingesetzt werden, welche bei gleich bleibender Formgebung an keiner Stelle über die Höhe der Tragelemente bzw. der Zargen der Tragelemente vorragen. Bei entsprechend steifen Materialien für die Zarge und insbesondere bei einstückiger Ausbildung mit der Dachhaut kann die selbsttragende Konstruktion auch auf Armierungsbänder verzichten und unmittelbar mit den Verbindern verschraubt werden.Modular elements for a prefabricated roof box of the type mentioned are formed according to the invention frame-shaped and have at their side surfaces connecting points for connectors of two adjacent support elements. The side surfaces can also be formed reinforced with drawstrings. Such a construction allows the use of particularly lightweight materials, since the required stability is ensured by the arranged on the side surfaces drawstrings. The drawstrings can also take the necessary for the secure connection of the modular elements loads and this even if for the frame or the frame construction of the support element light and static less resilient building materials are used. A load on the support elements in the longitudinal direction of the drawstrings is avoided in particular when the mutual connection of the drawstrings of adjacent support elements takes place in such a way that the support elements themselves do not touch one another, ie are arranged at a distance from one another. Such a connection of adjacent support elements can preferably be realized with uniformly shaped connectors, if, as it corresponds to a development of the invention, the training is such that in each case two mutually parallel drawstrings are fixed to the side surfaces of the frames, which with the roof top Include sharp angles. The fact that the drawstrings are not arranged parallel to the roof top edge or the plane of the roof skin, simple and very stable connector can be used with cruciform cross-section, which protrude with constant shape at any point on the height of the support elements or the frames of the support elements , In accordance with rigid materials for the frame and especially in one-piece design with the roof skin, the self-supporting construction can dispense with reinforcing tapes and bolted directly to the connectors.

Mit Vorteil sind die Verbinder von einen kreuzförmigen Querschnitt aufweisenden Verbindungsträgern gebildet, wobei, wie bereits erwähnt, in besonders einfacher Weise eine entsprechende Dichtheit der Dachhaut dann gewährleistet werden kann, wenn die Dachhaut von einer Blecheindeckung gebildet ist.Advantageously, the connectors of a cross-shaped cross-section having connecting members are formed, wherein, as already mentioned, in a particularly simple manner a corresponding Tightness of the roof skin can then be ensured if the roof skin is formed by a sheet metal covering.

Eine besonders niedrig bauende und damit transportfreundliche Ausgestaltung der Tragelemente bzw. der Einzelelemente lässt sich dadurch erreichen, dass zwei einander gegenüberliegende Seitenflächen der Zargen prallelogrammförmigen oder trapezförmigen Umriss aufweisen und zwei in Höhenrichtung versetzte Stirnflächen mit im Wesentlichen rechteckigem Querschnitt an die Seitenflächen angeschlossen sind. Derartig modulare Elemente können in beliebiger Weise gestapelt werden und unmittelbar für eine bestimmte Dachneigung vorgefertigt werden, wobei die Verbindung mit einfachen und für alle Elemente gleichen Verbindern ermöglicht wird. Eine trapezförmige Umrissform der Seitenflächen erlaubt hierbei die Ausbildung einer ebenen Unterkante bzw. Untersicht der Zargen.A particularly low-build and thus transport-friendly design of the support elements or the individual elements can be achieved in that two opposing side surfaces of the frames have a concave or trapezoidal outline and two offset in the vertical direction end faces are connected with a substantially rectangular cross-section of the side surfaces. Such modular elements can be stacked in any way and prefabricated directly for a particular roof pitch, the connection is made possible with simple and for all elements the same connectors. A trapezoidal outline of the side surfaces allows the formation of a flat bottom edge or bottom view of the sides.

Die Dichtheit der Dachhaut lässt sich im Fall von Blecheindeckungen in einfacher Weise dadurch gewährleisten, dass die Blecheindeckung an der höher liegenden Stirnfläche aufwärts und an der niedriger liegenden Stirnfläche abwärts gewinkelt bzw. abgekantet ausgebildet ist.The tightness of the roof skin can be ensured in the case of sheet metal roofs in a simple manner by the fact that the sheet metal cover is formed at the higher end face upwards and at the lower end face downwardly bent or bent.

In Falllinie bzw. Abflussrichtung wird die Dichtheit derartiger Fertigteildachbauelemente durch die Überlappung bzw. das Übergreifen der aufwärts bzw. abwärts gewinkelt bzw. abgekanteten Enden der Blecheindeckung gewährleistet. In dem quer zu dieser Richtung verlaufenden Anschlussbereich können jeweils aufwärts ragende Stege bzw. Aufkantungen vorgesehen sein, wobei dann die Dichtheit in einfacher Weise dadurch gewährleistet werden kann, dass für einander benachbarte aufwärts ragende Stege bzw. Aufkantungen der Blecheindeckung im Querschnitt U-förmige Abschluss- bzw. Dichtleisten angeordnet sind.In the fall line or outflow direction, the tightness of such prefabricated roof elements is ensured by the overlapping or overlapping of the upward or downward angled or bent ends of the sheet metal covering. In each case upwardly projecting webs or upstands may be provided in the connecting region extending transversely to this direction, in which case the tightness can be ensured in a simple manner by virtue of the fact that adjacent upwardly projecting webs or raised edges of the sheet metal cover have a U-shaped cross-section. or sealing strips are arranged.

Besonders klein bauende und stabile Verbinder lassen sich dadurch erzielen, dass die kreuzförmigen Querschnitt aufweisenden Verbindungsträger an ihrer Oberkante und/oder Unterkante nach Art einer vierseitigen Pyramide abgeschrägte Kanten aufweisen.Particularly small and stable connectors can be achieved in that the cross-shaped cross-section having connecting carrier at its upper edge and / or lower edge in the manner of a four-sided pyramid have bevelled edges.

Die Erfindung wird nachfolgend anhand von in der Zeichnung schematisch dargestellten modularen Elementen für die Herstellung eines Fertigteildaches näher erläutert. In dieser zeigen Fig.1 eine perspektivische Ansicht eines ersten modularen Einzelelementes mit ebener Dachhaut, Fig.2 zwei miteinander verbundene abgewandelte modulare Elemente in der Darstellung entsprechend Fig.1, Fig.3 ein Eckelement mit in der Vertikalprojektion gleichem Grundriss und einer Firstkante, Fig.4 eine Mehrzahl von miteinander verbundenen Ichsenelementen, welche jeweils den dreifachen modularen Grundriss aufweisen, Fig.5 eine Seitenansicht eines Modularelements teilweise im Schnitt und Fig.6 und Fig.7 eine Draufsicht bzw. eine perspektivische Ansicht eines Grundrissbeispiels, bei welchen die modularen Elemente zur Dachdeckung verwendet wurden.The invention will be explained in more detail with reference to modular elements schematically illustrated in the drawing for the production of a prefabricated roof. 1 shows a perspective view of a first modular single element with a flat roof skin, FIG. 2 two mutually connected modified modular elements in the representation according to FIG. 1, FIG. 3 shows a corner element with the same plan in the vertical projection and a ridge edge, FIG 4 shows a side view of a modular element partly in section and FIG. 6 shows a top view or a perspective view of a plan example in which the modular elements were used for roofing.

In Fig.1 ist ein selbsttragendes Fertigteildacheinzelelement dargestellt, welches ein kastenförmiges Tragelement 1 aufweist, an welchem über eine Mehrzahl von Schrauben 2 jeweils Zugbänder 3 festgelegt sind. Die zueinander jeweils parallel angeordneten Zugbänder 3 verlaufen an den Stirnflächen 4 des Tragelementes 1 zur Ebene der Dachhaut 5 parallel, wohingegen sie an den Seitenflächen 6 zur Ebene der Dachhaut 5 geneigt verlaufen. Die Seitenflächen 6 des zargenförmigen Grundkörpers des Tragelementes 1 weisen hiebei den Umriss eines Trapezes auf, wohingegen die Stirnflächen 4 im Wesentlichen einen rechteckigen Umriss aufweisen.FIG. 1 shows a self-supporting finished part single element which has a box-shaped support element 1, on which tension strips 3 are respectively fastened by means of a plurality of screws 2. The mutually parallel tension bands 3 extend parallel to the end faces 4 of the support element 1 to the plane of the roof skin 5, whereas they extend inclined to the side surfaces 6 to the roof skin 5 level. The side surfaces 6 of the frame-shaped base body of the support element 1 hiebei the outline of a trapezoid, whereas the end faces 4 have a substantially rectangular outline.

Die Dachhaut 5 ist hiebei als Blechdach ausgebildet und weist in Falllinie einander übergreifende Falze auf, wobei der jeweils vertikal abwärts gekantete Abschnitt 7 einen aufwärts gekanteten Abschnitt 8 des nachfolgenden Einzelelementes übergreift. Zur Verbindung benachbarter Tragelemente und damit benachbarter Einzelelemente sind im Querschnitt im Wesentlichen kreuzförmige Verbindungsträger 9 vorgesehen, deren Oberkante 10 zu einem gemeinsamen Knotenpunkt 11 pyramidenförmig verlaufen, sodass der Verbindungsträger nicht über die Dachhaut vorragt und dennoch in Höhenrichtung aneinander anschließende Tragelemente und damit aneinander anschließende Einzelelemente sicher verbinden kann. Die zur Dachhaut 5 geneigt verlaufenden Zugbänder 3 ermöglichen hiebei den Anschluss jeweils gleich ausgestalteter Verbindungsträger 9.The roof skin 5 is hiebei formed as a sheet metal roof and has in case of line cross-folds, wherein the respective vertically downwardly bent portion 7 a upwardly folded portion 8 of the subsequent single element overlaps. For connecting adjacent support elements and thus adjacent individual elements substantially cross-shaped connection carrier 9 are provided in cross-section, the upper edge 10 to a common node 11 in a pyramid shape, so that the connection carrier does not protrude beyond the roof and yet in the height direction adjoining support elements and thus adjoining individual elements safely can connect. The inclined to the roof skin 5 extending drawstrings 3 hiebei allow the connection of the same equally designed connection carrier. 9

Bei der Ausbildung nach Fig.2 sind jeweils Tragkörper 1 und Dachhaut 5 einstückig miteinander ausgebildet, wobei auf außen liegenden Armierungen bzw. Zugbänder verzichtet wurde.2 shows two modified modular square elements with a module edge length a can be seen, which are tightly interconnected. In the embodiment according to Figure 2 each support body 1 and roof skin 5 are integrally formed with each other, was dispensed with outside reinforcements or drawstrings.

Bei der Darstellung nach Fig.3 weist das im Grundriss bzw. der Vertikalprojektion quadratische Einzelelement einen Grat 12 auf, wodurch sich Abschlusselemente realisieren lassen, an welche an den aufgekanteten seitlichen Bereichen 14 der Verblechung wiederum modulare Grundelemente, wie sie in Fig.1 dargestellt sind, angeschlossen werden können. Der dichte Anschluss wird durch nicht dargestellte U-förmige Leisten gewährleistet, welche benachbarte aufgekantete Bereiche 13 und 14 übergreifen.In the illustration according to FIG. 3, the single element in the ground plan or the vertical projection has a ridge 12, whereby closure elements can be realized, to which at the upturned lateral regions 14 of the lamination again modular basic elements, as shown in FIG , can be connected. The tight connection is ensured by U-shaped strips, not shown, which overlap adjacent upended portions 13 and 14.

Bei der Darstellung nach Fig.4 sind nun Ichsenelemente 15 ersichtlich, welche in der Draufsicht jeweils aus drei eine quadratische Vertikalprojektion mit der Modulkantenlänge a aufweisenden Teilen bestehen und einstückig mit im wesentlichen L-förmiger Draufsicht ausgebildet sind. Die beiden seitlichen Teile 16 und 17 sind hiebei mit einem zentralen Teil 18 einstückig ausgebildet, sodass das Ichsenelement 15 insgesamt die dreifache Grundfläche des modularen quadratischen Querschnittes der Einzelelemente aufweist. Dies erlaubt die seitliche Verbindung mit Einzelelementen, wie sie in Fig.1 dargestellt sind, unter Einhaltung des gleichen Rastermaßes, wobei die Kombination von drei derartigen Rasterelementen zu einem gemeinsamen Ichsenelement 15 den Vorteil hat, dass an den gedachten Berührungslinien 19 auf die im Fall von benachbarten Einzelelementen ersichtliche Aufkantung 13 oder 14 verzichtet werden kann, sodass sich eine zusammenhängende Fläche für den Abfluss von Regenwasser ausbilden lässt, welches längs der Ichse in Falllinie abfließen kann.In the illustration of Figure 4 now Ichsenelemente 15 can be seen, which consist in plan view each of three a square vertical projection with the module edge length having a parts and are integrally formed with a substantially L-shaped plan view. The two lateral parts 16 and 17 are hiebei integrally formed with a central part 18, so that the ichsen element 15th has a total of three times the base area of the modular square cross-section of the individual elements. This allows the lateral connection with individual elements, as shown in Figure 1, while maintaining the same pitch, the combination of three such raster elements to a common Ichsenelement 15 has the advantage that at the imaginary lines of contact 19 in the case of adjacent uprights 13 or 14 can be dispensed with, so that a contiguous area can be formed for the outflow of rainwater, which can flow along the Ise in fall line.

In Fig.5 sind zwei miteinander verbundene modulare Grundelemente entsprechend der Fig.2 in der Seitenansicht teilweise im Schnitt dargestellt, wobei die Seitenwangen 6 der Tragelemente im wesentlichen trapezförmigen Umriss aufweisen, sodass sicht trotz des Höhenversatzes im Bereich der einander übergreifenden Ab- bzw. Aufkantungen 7 bzw. 8 der Dachhaut 5 eine ebene Unterkante 20 ergibt.In Figure 5, two interconnected modular basic elements are shown partially in section in the side view in Fig. 2, wherein the side walls 6 of the support elements have substantially trapezoidal outline, so view despite the height offset in the region of the overlapping Ab- or Aufkantungen 7 and 8 of the roof skin 5 results in a flat bottom edge 20.

Mit den gezeigten drei modularen Einzelelementen, welche jeweils selbsttragend ausgebildet sind, lassen sich unterschiedliche Grundrisse eindecken, wobei eine Abdichtung zwischen benachbarten Grundelementen entsprechend Fig.1 durch Aufschieben eines im Querschnitt im Wesentlichen U-förmigen, in Fig.1 nicht dargestellten, Teiles auf benachbarte aufwärts ragende Flansche 13 der Dachhaut erzielt wird. Beispiele für derartige Grundrisse sind in den Fig.6 bzw. Fig.7 dargestellt, wobei hier die modularen Grundelemente mit 21, die modularen Gratelemente mit 22 und die modularen Ichsenelemente mit 23 bezeichnet sind.With the three modular individual elements shown, which are each designed to be self-supporting, different floor plans can be covered, wherein a seal between adjacent basic elements according to Figure 1 by pushing a substantially U-shaped in cross-section, not shown in Figure 1, part to adjacent Upwardly projecting flanges 13 of the roof skin is achieved. Examples of such floor plans are shown in FIGS. 6 and 7, in which the modular base elements are designated by 21, the modular ridge elements by 22 and the modular earth elements by 23.
