Description
Balkenrost als Traggerippe einer Deckenkonstruktion mit viereckigen Grundrißflächen Es ist bekannt, daß zur Eindeckung von rechteckigen Deckenflächen am Umfang gelagerte und in den beiden Hauptachsenrichtungen bewehrte Deckenplatten aus Eisenbeton mit großem Vorteil verwendet werden können, da die im Bereich der Ecken auftretenden diagonalen Momente (Drillungsmomente) eine erhebliche Entlastung des übrigen Deckenfeldes bewirken. Die Anwendung dieser kreuzweise gespannten Deckenplatten ist indessen in Anbetracht des schnell anwachsenden Eigengewichtes auf kleinere Spannweiten beschränkt.Beam grating as a supporting framework of a ceiling construction with square Ground plan areas It is known that to cover rectangular ceiling areas Ceiling slabs supported on the circumference and reinforced in the two main axis directions made of reinforced concrete can be used with great advantage, since those in the area of Diagonal moments (torsional moments) occurring in corners provide considerable relief of the rest of the ceiling field. The use of these cross-tensioned ceiling tiles is, however, smaller in view of the rapidly growing weight Limited spans.
Es ist ferner bekannt, daß zur Eindeckung von größeren mehreckigen Deckenflächen als Traggerippe Scharen von sich kreuzenden Deckenbalken verwendet werden können; dieselben liegen dann zu den Umfassungslinien parallel oder verbinden kreuzweise die beiden Längsseiten. Bei dieser Anordnung wird in der Hauptsache eine Verteilung der Knotenlasten auf zwei oder mehrere Tragglieder bewirkt, nicht aber eine besondere Verminderung der maßgebenden Feldmomente, da keine Drillungsmomente entstehen können.It is also known that to cover larger polygonal Ceiling surfaces used as a supporting framework for multitudes of intersecting ceiling beams can be; they then lie parallel to or connect to the circumferential lines cross the two long sides. With this arrangement there is mainly one Distribution of the nodal loads on two or more support members causes, but not a special reduction in the decisive field moments, as there are no torsional moments can arise.
Gegenstand vorliegender Erfindung ist eine besondere Anordnung der Deckenbalken zu den Auflagemauern o. dgl., die nicht nur eine Lastverteilung bewirkt, sondern auch Drillungsmomente von gewünschter Größenanordnung zur Entlastung der Feldmomente schafft. Bei gleicher Feldgröße und Belastung ergeben sich dann Feldmomente, die mindestens um 40 °/o kleiner sind als die bei der bisher üblichen Anordnung, mithin kann an Deckenstärke und an Bewehrung erheblich gespart werden.The present invention is a special arrangement of the Ceiling beams to the supporting walls or the like, which not only causes load distribution, but also torsional moments of the desired size arrangement to relieve the Creates field moments. With the same field size and load, there are then field moments, which are at least 40% smaller than those in the conventional arrangement, this means that considerable savings can be made in terms of slab thickness and reinforcement.
In Abb. i ist eine Ausführungsart der neuen Tragkonstruktion schematisch dargestellt. Der Diagonal'balken a. ruht auf dem kurzen Eckbalken b auf. Biegt sich das Feld unter der Belastung durch, so dreht sich der Balken a um den weniger nachgiebigen Auflagerpunkt im Balken b, d. h. versucht sich von der Ecke abzuheben. Der Widerstand hiergegen erzeugt ein Gegenmoment und somit eine entsprechende Verringerung des Feldmomentes, wobei die Zwischenbalken c zum Lastenausgleich beitragen.An embodiment of the new supporting structure is schematically shown in Fig. I shown. The diagonal bar a. rests on the short corner beam b. Bends the field under the load through, the bar a rotates around the less flexible Support point in the beam b, d. H. tries to stand out from the corner. The resistance against this generates a counter-torque and thus a corresponding reduction in the Field moment, where the intermediate bars c contribute to load balancing.
In Abb. a ist der Leitgedanke der Erfindung weiter schematisiert. Die Einteilung der Feldmitte c ist für die Wirkungsweise des Tragwerks nicht von ausschlaggebender Bedeutung. Wesentlich ist der Diagonalbalken a als Verbindungsglied zwischen Feld und Ecke im Zusammenhang mit dem Eckbalken b.In Fig. A, the main idea of the invention is further schematized. The division of the field center c is not of importance for the mode of operation of the structure crucial importance. The diagonal bar a is essential as a connecting link between field and corner in connection with the corner beam b.
