Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand .der Erfindung ist ein aus Blech hergestellter Träger für Decken mit gröfseren Spannweiten, , welcher die Herstellung der Decken in einfacher und billiger Weise ermöglicht. The subject of the invention is a sheet metal carrier for ceilings with larger ones Spans, which enables the production of the ceilings in a simple and inexpensive manner.
Der Träger besteht aus gewöhnlichem Schwarzblech und bildet im Querschnitt ein gleichschenkliges Dreieck, von welchem die beiden Schenkel als Widerlager für die Deckensteine dienen.The carrier consists of ordinary black plate and forms a cross-section isosceles triangle, of which the two legs act as an abutment for the Ceiling stones are used.
In der beiliegenden Zeichnung stellenPlace in the accompanying drawing
Fig. ι und 2 Querschnitte derartiger Träger undFig. Ι and 2 cross sections of such carriers and
Fig. 3 und 4 Längenschnitte derselben dar.Fig. 3 and 4 are longitudinal sections of the same.
Fig. 5 zeigt einen Querschnitt einer unter Verwendung dieser Träger hergestellten massiven Decke.Fig. 5 shows a cross section of a solid made using these carriers Ceiling.
Die Ausführung der Träger geschieht in der Weise, dafs diese auf der Baustelle zunächst genau abgelängt, sodann mit einer aus Stützen und Zugstangen bestehenden Armirung versehen und schliefslich mit Cementmörtel ausgegossen werden. Die Träger werden dann, nachdem der Mörtel abgebunden hat, in entsprechenden Abständen verlegt, worauf man die Steine zwischen den Trägern ohne Schalung oder Lehrgerüst vermauert. Die im Innern des Trägers angeordnete Stütze ist in der Zeichnung ebenfalls dargestellt; sie besteht nämlich aus unter der Trägermitte angeordneten Flacheisen α b und c im Dreieckverband, wobei die bei d durch das eigentliche Stützeisen α hindurchgeführte Zugstange e in bekannter Weise die auf die Trägermitte wirkende Last auf die Trägerenden überträgt. Die Zugstange e ist an beiden Enden des Trägers in gleichfalls bekannter Weise durch eine dort angeordnete Verschlufsplatte geführt und mit Gewinde und Mutter zum festen Anziehen versehen. Statt der soeben besprochenen kann auch eine aus α und b allein gebildete, mit mehreren Zugstangen efg h versehene Armirung angeordnet werden (Fig. 4), die für gröfsere Belastungen bestimmt ist.The construction of the girders is done in such a way that they are first precisely cut to length on the construction site, then provided with a reinforcement consisting of supports and tie rods and finally poured with cement mortar. After the mortar has set, the girders are then laid at appropriate intervals, whereupon the stones are bricked up between the girders without formwork or falsework. The support arranged inside the carrier is also shown in the drawing; it consists namely of the carrier center arranged flat iron α b and c in the trefoil formation, wherein the through-run draw bar at d α by the actual back iron e transmits in known manner the load acting on the support center on the beam ends. The pull rod e is passed at both ends of the carrier in a likewise known manner through a locking plate arranged there and provided with a thread and nut for tight tightening. Instead of the one just discussed, a reinforcement formed from α and b alone and provided with several tie rods efg h can be arranged (Fig. 4), which is intended for greater loads.
