Abstract
A cupola for a large building is supported on a framework formed by a number of separate frames. Each frame consists of two curved upper members (4) arranged parallel to each other and a single lower member (5) which is more sharply curved than the two upper members (4). The two upper members are connected to each other by cross members (9) and each upper member is connected to the lower member by struts (6) of different lengths to produce a structure of triangular cross-section. The size of the triangle is a minimum at the middle of the frame and a maximum at each end. USE - Buildings with large span roofs without any intermediate supports.
Description
Die Erfindung bezieht sich auf ein Tragwerk für Gebäude mit kuppelartiger Innenraumbegrenzung.
Mit der Erfindung soll die Aufgabe gelöst werden, Gebäude - insbesondere Hallen - in Leichtbauweise mit einer stützenfreien grossen Spannweite und vergleichsweise grosser Scheitelhöhe erstellen zu können.
Diese Aufgabe wird durch die im Kennzeichen des Anspruches 1 genannten Merkmale gelöst.
Als Folge der optimalen Kraftübertragung ist es auch bei grosser Spannweite möglich, mit vergleichsweise leichten Bauteilen auszukommen.
Ausserdem ergibt sich auch eine unter ästhetischen Gesichtspunkten ansprechende Gestaltung.
In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. Es zeigen:
Fig. 1 eine Ansicht eines erfindungsgemässen Tragwerkes
Fig. 2 eine perspektivische Ansicht einer Tragelement-Hälfte vor dem Zusammenbau
Fig. 3 eine Ausführungsvariante der Abstützung.
Das Tragwerk ist bestimmt für Gebäude, insbesondere Hallen oder dgl., deren Innenraum 2 kuppelförmig begrenzt ist. Zwei gleich vorfabrizierte Tragelemente 1 gemäss Fig. 2 werden im Scheitel entlang einer Trennfuge 12 zusammengefügt.
Jedes Tragelemente 1 enthält zwei zueinander parallele, voneinander in Horizontalrichtung distanzierte, gewölbte Obergurten 4 und im Abstand unterhalb derselben einen stärker gebogenen Untergurt 5.
Jeder Obergurt ist durch lamellenförmige, geradlinige Streben 6 mit dem Untergurt 5 kraftschlüssig verbunden. Diese Streben 6 haben entlang den Gurten 4, 5 unterschiedliche Längen und unterschiedliche Neigungen. An den Aussenseiten sind diese Streben 6 am längsten und nehmen gegen den Scheitelpunkt kontinuierlich ab. Ein an die Aussenseiten der Lamellen 6 angelegtes imaginäres Band beschreibt eine verwundene Form. Die Stützen 7 bilden zusammen mit den Deckenelementen 9 eine Dreieckform, deren Inhalt gegen den Scheitel sukzessive abnimmt. Der Untergurt 5 wird beidseits durch auf dem Boden 3 ruhende innere Stützen 7 abgestützt. Die Stützstellen sind vorzugsweise als Gelenke 14 ausgebildet. Die beiden Obergurten 4 werden durch äussere Stützen 8 abgestützt, die höher sind als die innern Stützen 7.
Die Stützfläche 16 ist vorzugweise als ein in Grenzen linear verschiebbares Gleitlager ausgebildet, um unterschiedliche Durchbiegung der Obergurten 4 auszugleichen. Die äussern Stützen 8 können auch als Teil einer Gebäudewand ausgebildet werden.
Die beiden Obergurten 4 sind durch quer zur Längsrichtung der Gurten verlaufende Deckenelemente - insbesondere Holzbretter - überdeckt und verbunden. Oberhalb dieser Deckenelemente befindet sich vorzugsweise eine Wärmedämmschicht und darüber eine Deckhaut 10 aus konventionellem Material.
Obergurten 4 und Untergurt 5 werden vorzugsweise als gebogen verleimte Holzträger ausgebildet. Die Streben 6 sind ebenfalls vorzugsweise aus Holz und haben einen gleichbleibenden rechteckigen Querschnitt, wobei die längere Achse quer zur Gurtlängsrichtung verläuft.
In Fig. 3 ist eine Ausführungsvariante für die Abstützung der Obergurten 4 dargestellt. Hier werden die auf die Obergurten wirkenden Kräfte durch ein Gelenk 18 aufgenommen, das an einer starren Wand 20, beispielsweise einer Gebäudewand abgestützt ist.
Für eine Halle oder dgl. werden mehrere der beschriebenen Tragelemente 1 hintereinander angeordnet und oben miteinander verbunden.
Durch die Möglichkeit der Vorfabrikation ist ein rascher Baufortschritt am Bauplatz möglich.
An Stelle von Holz könnten für die Tragelemente 1 auch andere geeignete Materialien treten.
Bei einer typischen Ausführungsform beträgt der horizontale Abstand zwischen den Stützen 7 etwa das 1,5fache der Scheitelhöhe.
The invention relates to a structure for buildings with a dome-like interior boundary.
The object of the invention is to be able to create buildings - in particular halls - in a lightweight construction with a column-free large span and a comparatively large apex height.
This object is achieved by the features mentioned in the characterizing part of claim 1.
As a result of the optimal power transmission, it is possible to get by with comparatively light components even with a large span.
In addition, there is also an aesthetically appealing design.
Exemplary embodiments of the subject matter of the invention are shown in the drawing. Show it:
Fig. 1 is a view of a structure according to the invention
Fig. 2 is a perspective view of a support element half before assembly
Fig. 3 shows a variant of the support.
The structure is intended for buildings, in particular halls or the like. The interior of which is delimited in a dome shape. Two identical prefabricated support elements 1 according to FIG. 2 are joined at the apex along a parting line 12.
Each support element 1 contains two arched upper chords 4 which are parallel to one another, distanced from one another in the horizontal direction, and a more curved lower chord 5 at a distance below them.
Each upper chord is non-positively connected to the lower chord 5 by lamellar, straight struts 6. These struts 6 have different lengths and different inclinations along the belts 4, 5. These struts 6 are longest on the outside and decrease continuously towards the apex. An imaginary band applied to the outside of the slats 6 describes a twisted shape. The supports 7 together with the ceiling elements 9 form a triangular shape, the content of which gradually decreases towards the apex. The lower flange 5 is supported on both sides by inner supports 7 resting on the floor 3. The support points are preferably designed as joints 14. The two upper chords 4 are supported by outer supports 8, which are higher than the inner supports 7.
The support surface 16 is preferably designed as a sliding bearing that can be displaced linearly within limits in order to compensate for different deflection of the upper chords 4. The outer supports 8 can also be formed as part of a building wall.
The two upper straps 4 are covered and connected by ceiling elements running transversely to the longitudinal direction of the straps - in particular wooden boards. A thermal insulation layer is preferably located above these ceiling elements and a cover skin 10 made of conventional material is located above it.
Upper chords 4 and lower chord 5 are preferably designed as curved, glued wooden beams. The struts 6 are also preferably made of wood and have a constant rectangular cross section, the longer axis running transversely to the longitudinal direction of the belt.
FIG. 3 shows an embodiment variant for supporting the upper chords 4. Here the forces acting on the upper chords are absorbed by a joint 18 which is supported on a rigid wall 20, for example a building wall.
For a hall or the like, several of the support elements 1 described are arranged one behind the other and connected to one another at the top.
Thanks to the possibility of prefabrication, rapid construction progress on the construction site is possible.
Instead of wood, other suitable materials could also be used for the support elements 1.
In a typical embodiment, the horizontal distance between the supports 7 is approximately 1.5 times the apex height.
