Abstract

The spatial support structure, e.g. for the mounting of a facade at a building, has two parallel support assemblies (1,2), where their neighboring intersections (3,4) are connected with each other by orthogonal pressure rods (5). The tensioning cables (11-14) between the structures have diagonal cable sections (11a-14a), so that the start and end of each cable are secured to the same structure. Each cable is passed longitudinally through the support assembly intersections, with a cable diagonal section gripping both ends of all the rods (5.1-5.5). An external anchor (9) blocks any relative movements between the two support assemblies.

Description

Die Erfindung betrifft eine räumliche Tragwerksanordnung mit zwei parallel im Abstand zueinander angeordneten ebenen Tragwerken, wobei zueinander benachbarte Tragwerksknoten der beiden Tragwerke durch Orthogonal-Druckstäbe miteinander verbunden sind, und mit Spannseilen, die zwischen Tragwerksknoten der beiden Tragwerke verlaufende Diagonal-Seilabschnitte aufweisen.The invention relates to a spatial structure arrangement with two parallel planes spaced apart Structures, with adjacent structural nodes of the two structures by orthogonal compression rods are connected to each other, and with tension cables, which between the structure nodes of the two structures Have diagonal rope sections.

Räumliche Tragwerksanordnungen, die zwei parallele ebene Tragwerke aufweisen, müssen durch Diagonal-Verstrebungen stabilisiert werden. Ein typisches Ausführungsbeispiel solcher räumlichen Tragwerksanordnungen sind zweischalige Gebäudefassaden, die aus einem das eine Tragwerk bildenden inneren Fassadengitter und einem das andere Tragwerk bildenden äußeren Fassadengitter bestehen. Die Diagonal-Verstrebungen bestehen üblicherweise aus Spannseilen, die diagonal in den einzelnen Feldern der Tragwerksanordnung verlaufen und eine Auskreuzung dieser Felder bilden. Die Diagonal-Seile sind jeweils an ihren Enden mit den Tragwerksknoten verbunden, so daß ein mit Spannseilen ausgekreuztes Fachwerk gebildet wird.Spatial structure arrangements, the two parallel planes Structures must have diagonal struts be stabilized. A typical embodiment Such spatial structure arrangements are double-shell Facades of buildings that form a structure inner facade grille and one the other structure forming outer facade grid. The diagonal struts usually consist of tension cables that diagonally in the individual fields of the structure run and form an intersection of these fields. The Diagonal ropes are at their ends with the Structural nodes connected so that one with tensioning ropes crossed truss is formed.

Bei unsymmetrischem Zwang kann es zu hohen Beanspruchungen der Elemente der Tragwerksanordnung, insbesondere der Diagonal-Spannseile kommen. Diese Beanspruchungen können die Materialfestigkeit übersteigen, so daß es zu einem Bruch und sogar zu einem Versagen der gesamten räumlichen Tragwerksanordnung kommen kann. Diese Gefahr besteht insbesondere bei Leichtbauweise. Eine Abhilfemöglichkeit besteht bisher nur darin, eine Überdimensionierung der Stäbe und Spannseile der Tragwerksanordnung vorzusehen, um einem Stabilitätsversagen vorzubeugen. Damit wird von der angestrebten Leichtbauweise aber wieder abgewichen.In the case of asymmetrical constraints, high stresses can arise the elements of the structure, in particular the Diagonal tensioning ropes come. These strains can exceed the material strength, so that it becomes a Breakage and even failure of the entire spatial Structural arrangement can come. This is a danger especially with lightweight construction. A remedy so far only consists of overdimensioning the To provide rods and tension cables of the structure arrangement to to prevent stability failure. So that from the desired lightweight construction deviated again.

Aufgabe der Erfindung ist es daher, eine räumliche Tragwerksanordnung der eingangs genannten Gattung zu schaffen, bei der auch bei Leichtbauweise eine Überbeanspruchung von Bauelementen der Tragwerksanordnung vermieden wird.The object of the invention is therefore a spatial Structure arrangement of the type mentioned at the beginning create, even with a lightweight construction Overuse of components of the structure arrangement is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jedes Spannseil nur an seinen beiden Seilenden an dem selben Tragwerk verankert ist, daß jedes Spannseil an den von ihm durchlaufenen Tragwerksknoten längsbeweglich geführt ist, und daß an den Tragwerksknoten an beiden Enden jedes Orthogonal-Druckstabs jeweils mindestens ein Diagonal-Seilabschnitt angreift.This object is achieved in that each tension rope only on its two rope ends on the same structure is anchored that each tensioning rope to the the structure nodes it traverses are longitudinally movable is guided, and that at the structural nodes at both ends each orthogonal push rod at least one Diagonal rope section attacks.

Da die Spannseile nicht an jedem Tragwerksknoten, sondern nur an den Seilenden fest angeschlossen sind und an den übrigen Tragwerksknoten durchlaufen, können Verformungen, die sich aus auf die Tragwerksanordnung einwirkenden Zwang ergeben, weitestgehend spannungsfrei aufgenommen werden. Auch bei einer sich infolge des Zwangs ergebenden Relativverschiebung zwischen den beiden Tragwerken wird eine Überlastung der Spannseile vermieden. Because the tension cables are not at every structural node, but instead are only firmly attached to the rope ends and to the through the remaining structural nodes, deformations, the constraint acting on the structure result, are taken up largely without tension. Even with a result of the constraint Relative displacement between the two structures overloading of the tensioning ropes avoided.

Bei der Ausführung der räumlichen Tragwerksanordnung als zweischalige Gebäudefassade kann es insbesondere durch Temperaturunterschiede zu Relativverschiebungen zwischen den beiden Fassadengittern kommen. Die erfindungsgemäße Anordnung der Spannseile verhindert dabei, daß ein zu einem Stabilitätsversagen von Fassadenbauteilen führender Zwang entstehen kann.When executing the spatial structure arrangement as double-skin building facade can in particular by Temperature differences to relative shifts between the two facade grids. The invention Arrangement of the tensioning ropes prevents one from one Stability failure of facade components leading constraint can arise.

Gemäß einer Ausgestaltung des Erfindungsgedankens ist vorgesehen, daß die mögliche Relativverschiebung zwischen den beiden Tragwerken durch eine äußere Verankerung begrenzt ist. Damit wird konstruktiv eine Grenze der möglichen Relativverschiebungen zwischen den beiden Tragwerken vorgegeben, ohne daß beim Erreichen dieser Grenze die Gefahr eines Stabilitätsversagens besteht.According to an embodiment of the inventive concept provided that the possible relative shift between the two structures by an external anchor is limited. This will constructively limit the possible relative shifts between the two Structures specified without having reached them Limit there is a risk of stability failure.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Further advantageous embodiments of the The idea of the invention is the subject of further Dependent claims.

Die Erfindung wird nachfolgend an Ausführungsbeispielen näher erläutert, die in der Zeichnung dargestellt sind. Es zeigt:

  • Fig. 5 und 6 abgewandelte Ausführungsformen räumlicher Tragwerksanordnungen in Darstellungen gemäß der Fig. 1.
    • The invention is explained in more detail below using exemplary embodiments which are illustrated in the drawing. It shows:
  • 1 is a vertical section of a building facade as an example of a spatial structure arrangement of two flat structures in the undeformed state,
  • 2 shows the structure of FIG. 1 after a vertical relative displacement between the two structures,

  • Fig. 4 is a section along the line IV-IV in Fig. 3, and
  • 5 and 6 modified embodiments of spatial structure arrangements in representations according to FIG. 1st

    • Die in den Fig. 1-4 am Beispiel einer zweischaligen Gebäudefassade in Stahlbauweise dargestellte räumliche Tragwerksanordnung weist ein inneres ebenes Tragwerk 1 und ein äußeres ebenes Tragwerk 2 auf, die durch die beiden ebenen Gittertragwerke der Gebäudefassade gebildet werden. Die beiden Tragwerke 1 und 2 sind parallel und im Abstand zueinander angeordnet. Jeweils benachbarte Tragwerksknoten 3 und 4 der beiden Tragwerke 1, 2 sind jeweils durch einen Orthogonal-Druckstab 5 miteinander verbunden.1-4 using the example of a two-shell Building facade shown in steel construction spatial Structure arrangement has an inner planar structure 1 and an outer flat structure 2 on by the two flat lattice structures of the building facade are formed. The two structures 1 and 2 are parallel and at a distance arranged to each other. Neighboring structural nodes 3 and 4 of the two structures 1, 2 are each by a Orthogonal pressure rod 5 connected to each other.

    Das innere Tragwerk 1 ist durch Verankerungen 6, 7 mit tragenden Gebäudeteilen 8 verbunden. Das äußere Tragwerk 2 ist durch mindestens eine äußere Verankerung 9 an einer Gebäudewand 10 elastisch abgestützt, wodurch eine mögliche Relativverschiebung zwischen den beiden Tragwerken 1, 2 begrenzt ist.The inner structure 1 is anchored with 6, 7 load-bearing parts of the building 8 connected. The outer structure 2 is by at least one external anchor 9 Building wall 10 supported elastically, making a possible Relative displacement between the two structures 1, 2 is limited.

    Mehrere Spannseile 11, 12, 13 und 14 stabilisieren die räumliche Tragwerksanordnung. Aus der unterschiedlichen Strichdarstellung der Spannseile 11, 12, 13 und 14 in Fig. 1 erkennt man, daß jedes Spannseil 11, 12, 13 und 14 an seinen beiden Seilenden jeweils an dem selben Tragwerk 1 bzw. 2 verankert ist und das jedes Spannseil 11, 12, 13 und 14 zwischen Tragwerksknoten 3, 4 der beiden Tragwerke 1, 2 verlaufende Diagonal-Seilabschnitte 11a, 12a, 13a und 14a aufweist. Die beiden sich über die gesamte Höhe der Tragwerksanordnung erstreckenden Spannseile 11 und 12 weisen darüber hinaus Längs-Seilabschnitte 11b bzw. 12b auf.Several tensioning cables 11, 12, 13 and 14 stabilize the spatial structure. From the different Line representation of the tensioning cables 11, 12, 13 and 14 in Fig. 1 you can see that each tensioning rope 11, 12, 13 and 14 its two rope ends on the same structure 1 or 2 is anchored and that each tensioning cable 11, 12, 13 and 14 between structural nodes 3, 4 of the two structures 1, 2 extending diagonal rope sections 11a, 12a, 13a and 14a having. The two covered the entire height of the Supporting arrangement extending tension cables 11 and 12 also have longitudinal cable sections 11b and 12b on.

    Man erkennt, daß das Spannseil 11 am äußeren Tragwerksknoten 4 des in Fig. 1 obersten Orthogonal-Druckstabs 5.1 verankert ist. Ein Diagonal-Seilabschnitt 11a verläuft zu dem inneren Tragwerksknoten 2 des nächsten Orthogonal-Druckstabs 5.2. In den nächsten beiden Feldern und über den Orthogonal-Druckstab 5.3 hinweg verläuft das Spannseil 11 in zwei Längs-Seilabschnitten 11b bis zum inneren Knoten 3 des Orthogonal-Druckstabs 5.4 und von dort als Diagonal-Seilabschnitt 11a zum äußeren Tragwerksknoten 4 des in der Fig. 1 untersten Orthogonal-Druckstabs 5.5 und ist dort verankert. Symmetrisch hierzu verläuft das Spannseil 12, das jeweils an den inneren Tragwerksknoten 3 der Orthogonal-Druckstäbe 5.1 und 5.5 verankert ist.It can be seen that the tension cable 11 on the outside Structure node 4 of the uppermost orthogonal compression rod in FIG. 1 5.1 is anchored. A diagonal section of rope 11a runs to the inner structural node 2 of the next Orthogonal push rod 5.2. In the next two fields and this runs across the orthogonal pressure rod 5.3 Tension rope 11 in two longitudinal rope sections 11b to inner node 3 of the orthogonal compression rod 5.4 and from there as a diagonal rope section 11a to the outer structure node 4 of the lowest orthogonal push rod 5.5 and is anchored there. This runs symmetrically Tension rope 12, each on the inner structure node 3rd the orthogonal pressure rods 5.1 and 5.5 are anchored.

    Die beiden Spannseile 13 und 14 bestehen nur aus zwei Diagonal-Seilabschnitten 13a bzw. 14a. Das Spannseil 13 ist am äußeren Tragwerksknoten 4 des Orthogonal-Druckstabs 5.2 verankert und verläuft zum inneren Tragwerksknoten 3 des Orthogonal-Druckstabs 3 und von dort zu seiner Verankerung am äußeren Tragwerksknoten 4 des Orthogonal-Druckstabs 5.4. Das Spannseil 14 verläuft symmetrisch hierzu. Zu jedem an einem (1) der beiden Tragwerke (1, 2) verankerten Spannseil (12, 14) ist somit symmetrisch ein an dem jeweils anderen Tragwerk (2) verankertes Spannseil (11, 13) angeordnet. The two tension cables 13 and 14 consist of only two Diagonal rope sections 13a and 14a. The tension cable 13 is at the outer structural node 4 of the orthogonal compression rod 5.2 anchored and runs to the inner structural node 3 of the Orthogonal pressure rod 3 and from there to anchor it on the outer structural node 4 of the orthogonal compression rod 5.4. The tension cable 14 runs symmetrically to this. To everyone one (1) of the two structures (1, 2) anchored tension rope (12, 14) is thus symmetrical one to the other Structure (2) anchored tension cable (11, 13) arranged.

    Wie in den Fig. 3 und 4 gezeigt, ist das hier als Beispiel dargestellte Spannseil 12 an dem von ihm durchlaufenen Tragwerksknoten 4 längsbeweglich geführt. Das Spannseil 12 läuft über einen am Orthogonal-Druckstab 5.2 angeordneten Umlenksattel 15 und erstreckt sich durch eine Öffnung 16 des Orthogonal-Druckstabs 5.2. Der Diagonal-Seilabschnitt 13a des Spannseils 13 greift mittels eines Ösenspannschlosses 17 am Orthogonal-Druckstab 5.2 an.As shown in FIGS. 3 and 4, this is an example here shown tensioning rope 12 on the one he passed through Structural nodes 4 guided longitudinally. The tension rope 12 runs over a arranged on the orthogonal pressure rod 5.2 Deflection saddle 15 and extends through an opening 16 of the orthogonal push rod 5.2. The diagonal rope section 13a of the tensioning cable 13 engages by means of a Eyelet turnbuckle 17 on the orthogonal pressure rod 5.2.

    Fig. 2 zeigt die Tragwerksanordnung aus Fig. 1 nach einer Vertikalverschiebung des äußeren Tragwerks 2 relativ zu dem inneren Tragwerk 1. Die dadurch bedingte Längenänderung der Diagonalen der einzelnen Felder führt nicht zu einer Überbeanspruchung der Spannseile, weil diese an den Tragwerksknoten 3 bzw. 4 über die Umlenksättel 15 durchlaufen. Jedes Spannseil 11, 12, 13 und 14 weist zwei Diagonal-Seilabschnitte auf, von denen der eine in gleichem Maße verlängert wird, wie der jeweils andere Diagonal-Seilabschnitt verkürzt wird. Dadurch bleibt die Gesamtlänge des Spannseils unverändert.Fig. 2 shows the structure of Fig. 1 after a Vertical displacement of the outer structure 2 relative to that inner structure 1. The resulting change in length of the Diagonals of the individual fields do not lead to one Overstraining of the tensioning ropes, because these on the Structural nodes 3 and 4 via the deflection saddles 15 run through. Each tensioning rope 11, 12, 13 and 14 has two Diagonal rope sections, one of which is in the same Dimensions are extended like the other diagonal rope section is shortened. This keeps the overall length of the tension rope unchanged.

    Während beim Ausführungsbeispiel gemäß Fig. 1 eine gerade Anzahl von Feldern der Tragwerksanordnung dargestellt ist, nämlich vier Felder, sind in den Fig. 5 und 6 abgewandelte Ausführungsbeispiele mit fünf bzw. drei Feldern dargestellt. Man erkennt, daß auch hierbei jedes Spannseil nur an seinen beiden Seilenden an dem selben Tragwerk verankert ist und daß bei einer Relativverschiebung zwischen den beiden Tragwerken 1 und 2 die Seillängen unverändert bleiben, so daß eine Überlastung der Spannseile vermieden wird.While a straight in the embodiment of FIG. 1 Number of fields of the structure arrangement is shown, namely four fields are modified in FIGS. 5 and 6 Embodiments with five or three fields shown. It can be seen that here, too, each tensioning rope only on its two rope ends on the same structure is anchored and that with a relative displacement between the two structures 1 and 2 the rope lengths remain unchanged, so that an overload of the tensioning ropes is avoided.
