KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein im Querschnitt dreieckiger, aus zwei schrägen, in einem gemeinsamen Obergurt zusammenstoßenden Trägern gebildeter Hallenbinder mit rahmenartigen Stützfüßen.The subject of the invention forms a triangular cross-section, made of two oblique, Hall trusses formed in a common upper chord with colliding girders frame-like support feet.
Die Lagerung des Hallenbinders geschieht derartig, daß je zwei feste und zwei bewegliche Auflager einander diagonal gegenüberliegen. The storage of the hall girder is done in such a way that two fixed and two movable The supports are diagonally opposite each other.
ίο In der Zeichnung ist skizzenhaft durch die Fig. ι eine Ansicht, durch die Fig. 2 ein Grundriß des Binders mit Angabe der Lagerung dargestellt und durch die Fig. 3 ein senkrecht zu den Bindern geführter Schnitt durch die Dachfläche einer unter Verwendung der neuen Binder abgedeckten Halle.ίο In the drawing is sketchy through the Fig. Ι a view through which Fig. 2 is a plan view of the binder with details of the storage and by FIG. 3 is a section perpendicular to the binders through the roof of a hall covered using the new trusses.
Bei Wind von links in der Längsrichtung des Binders (vgl. Fig. 1) wird der Obergurt des Trägers T1 (vgl. Fig. 2) gezogen, der des Trägers T2 gedrückt; bei Wind von rechts tritt das Umgekehrte ein. Jedesmal heben sich im Obergurt die Spannkräfte teilweise auf. Es kommt sogar vor, daß die Gesamtkraft aus Winddruck in der Querrichtung des Gebäudes auf einzelne Obergurtstäbe entlastend wirkt.When there is wind from the left in the longitudinal direction of the girder (cf. FIG. 1), the upper chord of the carrier T 1 (cf. FIG. 2) is pulled, that of the carrier T 2 is pressed; in the case of wind from the right, the opposite occurs. Each time the tension forces in the upper chord are partially canceled out. It even happens that the total force from wind pressure in the transverse direction of the building has a relieving effect on individual upper chord bars.
Der für den Obergurt erforderliche Eisenquerschnitt wird daher durch die vorgesehene Lagerung des Trägers vermindert.The iron cross-section required for the top chord is therefore determined by the Reduced storage of the carrier.
Infolge wagerechter Kräfte quer zum Binder bleibt der Obergurt wie bei allen bekannten, aus zwei schrägliegenden, in einem gemeinsamen Obergurt zusammenstoßenden Fachwerken bestehenden Trägern spannungslos, da beispielsweise bei der in Fig. 3 gegebenen Art des Kraftangriffs der Obergurt des linken Trägers gedrückt, der des rechten dagegen in demselben Maße gezogen wird.As a result of horizontal forces across the girder, the upper chord remains as with all known, made of two inclined trusses that meet in a common upper flange Existing girders without tension, since, for example, in the type of force application given in FIG. 3, the upper belt of the left The carrier on the other hand is pulled to the same extent.
