Title
(DE) TRAGSTRUKTUR FÜR FREIFORMFLÄCHEN IN BAUWERKEN
(EN) SUPPORTING STRUCTURE FOR FREEFORM SURFACES IN BUILDINGS
(FR) STRUCTURE PORTEUSE POUR DES SURFACES DE FORME LIBRE DANS LE BÂTIMENT
Abstract
(DE)
Tragstruktur (8) für gekrümmte Hüllgeometrien in Bauwerken bestehend aus Trägerelementen (4), die jeweils zu die Hüllgeometrie aufspannende N-Ecken (N=3,4,...), die jeweils ein planares Flächenelement (5) umgrenzen, zusammengesetzt sind, und die Trägerelemente (4) aneinandergrenzender N-Ecke jeweils einen gemeinsamen Knotenbereich (3) bilden, in dem die Trägerelemente (4) zusammenstoßen, und in zumindest einem Abschnitt der Hüllgeometrie die Ebene eines Flächenelements (5) und die jeweiligen Ebenen der Flächenelemente (5) zweier in nicht - parallelen Raumrichtungen angrenzenden N-Ecken in unterschiedlichen Ebenen liegen. Erfindungsgemäß ist vorgesehen, dass die Trägerelemente (4) in diesem Abschnitt jeweils 4- oder 6 -Ecke bilden, und die Träger elemente (4) jeweils eine Längsachse (L) aufweisen, die sich geradlinig zwischen jeweils zwei Knotenbereichen (3) erstreckt und parallel zur gedachten Schnittlinie der ihm zugeordneten Flächenelementebenen verläuft, wobei der Querschnitt der Trägerelemente (4) normal zu deren Längsachse entlang der gesamten Längsachse des Trägerelements (4) jeweils einen relativen Drillwinkel von 0° aufweist.
(EN)
Supporting structure (8) for curved envelope geometries in buildings consisting of support elements (4) which are each combined to form N-sided polygons (N=3,4,...) which span the envelope geometry and which each enclose a planar surface element (5), and the support elements (4) of adjacent N-sided polygons each form a common node region (3) in which the support elements (4) abut, and the plane of a surface element (5) and the respective planes of the surface elements (5) of two N-sided polygons which adjoin in non-parallel spatial directions lie in different planes in at least one portion of the envelope geometry. According to the invention, the support elements (4) in this portion each form 4- or 6-sided polygons, and the support elements (4) each have a longitudinal axis (L) which extends in a straight line between in each case two node regions (3) and runs parallel to the imaginary intersection line of the surface element planes associated with said portion, wherein the cross section of the support elements (4) normal to their longitudinal axis in each case has a relative twist angle of 0° along the entire longitudinal axis of the support element (4).
(FR)
L'invention concerne une structure porteuse (8) pour des géométries de coque courbes dans le bâtiment, qui se compose d'éléments porteurs (4) qui sont assemblés à chaque fois pour former N coins (N=3, 4,…) sous-tendant la géométrie de coque, ces coins étant adjacents à un élément de surface plan (5). Les éléments porteurs (4) des N coins adjacents forment une région de nœud commune (3) par l'aboutement des éléments porteurs (4) les uns contre les autres. De plus, dans au moins une partie de la géométrie de coque, le plan d'un élément de surface (5) et les plans respectifs des éléments de surface (5) de deux des N coins adjacents dans des directions spatiales non parallèles sont situés dans des plans différents. Conformément à l'invention, les éléments porteurs (4) forment dans cette partie à chaque fois 4 ou 6 coins, et les éléments porteurs (4) présentent chacun un axe longitudinal (L) qui s'étend en ligne droite entre deux régions de nœud (3) et parallèlement à la ligne de coupe imaginaire du plan d'élément de surface associé. La section transversale des éléments porteurs (4) présente, perpendiculairement à leur axe longitudinal, le long de l'axe longitudinal total de l'élément porteur (4), un angle de torsion relatif de 0°.
