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.

PATENTANSPRUCH: Eisenbetonbalken; dadurch gekennzeich net, dass im Beton der Zugzone des Balkens Hohlsteine in Abstand voneinander angeordnet sind, welche einen durchgehenden Längs kanal aufweisen, durch welchen Armierungs- zugeisen hindurchgeführt sind, wobei der genannte Längskanal mit Beton ausgefüllt ist, so dass die Armierungseisen in ihrer ganzen Ausdehnung im Beton eingebettet sind. PATENT CLAIM: Reinforced concrete beams; characterized in that in the concrete of the tensile zone of the beam hollow stones are arranged at a distance from each other, which have a continuous longitudinal channel through which reinforcement bars are passed, said longitudinal channel being filled with concrete, so that the reinforcement bars in their entire extent are embedded in the concrete. UNTERANSPRÜCI1: Eisenbetonbalken nach Patentanspruch, dadurch gekennzeichnet, dass die Hohlsteine mindestens zwei übereinander liegende Längs kanäle aufweisen, und dass die Armierungs- zugeisen durch den untern Längskanal hin durchgeführt sind. SUB-CLAIM: Reinforced concrete beam according to patent claim, characterized in that the hollow bricks have at least two longitudinal channels lying one above the other, and that the reinforcing bars are passed through the lower longitudinal channel.
