Description
Eisenbetonbalken. Die vorliegende Erfindung hat einen unter Verwendung von Hohlsteinen hergestellten Eisenbetonbalken zum Gegenstand.
Gemäss der Erfindung sind die Hohlsteine im Abstand von einander in der Zugzone des Betons angeordnet und weisen einen durch gehenden Längskanal auf, durch welchen Armierungszugeisen hindurchgeführt sind; dabei ist dieser Kanal mit Beton ausgefüllt, so dass die Zugeisen in ihrer ganzen Aus dehnung in Beton eingebettet sind.
Die Zeichnung veranschaulicht in den Fig. 1, 2 und 3 ein Ausführungsbeispiel des Eisenbetonbalkens. Es zeigen: Fig. 1 die Seitenansicht, Fig. 2 eine perspektivische Ansicht, Fig. 3 einen Querschnitt des Balkens. Beim dargestellten Beispiel sind im Beton der Zugzone des Balkens Hohlsteine h in Abstand voneinander angeordnet.
Diese Hohl steine weisen beispielsweise drei übereinander angeordnete, durchgehende in der Längs richtung der Steine sich erstreckende Hohl räume auf, von welchen der untere b, durch welchen das Armierungseisen je hindurch geführt ist, mit Beton ausgefüllt ist, so dass die Zugarmierung auf ihrer ganzen Länge im Beton eingebettet bleibt. Die Druckzone d des Balkens, die an den Enden des Balkens liegenden Teile a, in denen sich die aufge bogenen Einlagen e befinden, sowie die Stege s zwischen den Hohlkörpern, in wel chen sich die Zug- und Druckzone verbin dende Bügel befinden, sind voll in Beton ausgeführt.
Reinforced concrete beams. The subject of the present invention is a reinforced concrete beam made using hollow blocks.
According to the invention, the hollow blocks are arranged at a distance from one another in the tensile zone of the concrete and have a continuous longitudinal channel through which reinforcement bars are passed; this channel is filled with concrete so that the pull bars are embedded in concrete in their entirety.
The drawing illustrates in FIGS. 1, 2 and 3 an embodiment of the reinforced concrete beam. The figures show: FIG. 1 the side view, FIG. 2 a perspective view, FIG. 3 a cross section of the beam. In the example shown, hollow stones h are arranged at a distance from one another in the concrete of the tension zone of the beam.
These hollow stones have, for example, three superposed, continuous in the longitudinal direction of the stones extending hollow spaces, of which the lower b, through which the reinforcing iron is ever passed, is filled with concrete, so that the tensile reinforcement over its entire length remains embedded in the concrete. The pressure zone d of the beam, the parts a lying at the ends of the beam, in which the bent inserts are located, and the webs s between the hollow bodies, in which the tension and pressure zone are connec dende stirrups, are full executed in concrete.
