   Balkenkonstruktion aus armiertem Beton. 



   Gegenstand der vorliegenden Erfindung ist eine Ausführungsform jener Balken und Gebäiko aus armiertem Beton, hei welchen in bekannter Weise in die Betonmasse als   Zuggurte   dienende gerade Eisenstangen sowie abgebogene Eisenstangen eingebettet sind, deren mittleres Stück horizontal in einer durch die Zugstangen gehenden Vertikalebene liegt, während die beiderseits sich   anschliessenden     Stangenstücke   schräg nach aufwärts gerichtet sind und welche gerade, aus Bandeisen U-förmig gestaltete und entsprechend der   Beanspruchung   des Balkens in diesem verteilte Bügel zur Verbindung der geraden mit den abgebogenen Eisenstangen aufweisen.

   Der Erfindung gemäss werden die abgebogenen Stangen mit ihren   wagerechten   Endteilen in das nächste Balkenfach verlängert und daselbst in bekannter Weiso mittelst nach abwärts gerichteter Bügel in den Beton eingebunden, so dass die über mehrere Stützpunkte reichenden ssetonbalken   als kontinuierliche Träger   wirken.

   Beam construction made of reinforced concrete.



   The subject of the present invention is an embodiment of those beams and buildings made of reinforced concrete, in which, in a known manner, straight iron bars and bent iron bars are embedded in the concrete mass serving as tension straps, the middle piece of which lies horizontally in a vertical plane passing through the tie bars, while the two sides adjoining rod pieces are directed obliquely upwards and which have straight, U-shaped made of iron band and according to the stress on the beam in this distributed bracket to connect the straight with the bent iron rods.

   According to the invention, the bent rods are extended with their horizontal end parts into the next beam compartment and there integrated into the concrete in the known manner by means of downwardly directed brackets, so that the sseton beams, which extend over several support points, act as continuous beams.

   The parts 2 ″ of the rod 2 that adjoin the inclined rod parts 2 ′ at the top

 are embedded in the beam parts located in C and extend with the ends 2 '″ protruding beyond the support or bearing points C of the beam into the beam compartment which is initially located.



   A lifting of these rod parts 2 '' 'is prevented by several brackets a pushed over them from above, the downwardly directed legs of which are firmly embedded in the concrete body. The rod ends 2 "1 extending in the opposite direction support the beam at the support point ('.

Claims

PATENT CLAIM: Beam construction made of reinforced concrete, equipped in a known manner with an iron bar 1 serving as a tension belt, bent iron bars 2, 2 ', 2 ", the middle piece 2 of which is horizontal and in the vertical plane of the bar 1, while the bar pieces 2' are in the same vertical plane the support point C are directed obliquely upwards, as well as with straight, U-shaped made of strip iron and corresponding <Desc / Clms Page number 2> the stress of the beam in this distributed bracket 8 for connecting the iron rods 1 with the bent iron rods 2, 2 ', 2 ", thereby marked,

that the bar 2 ″ running in the horizontal direction is extended to the bar 2 ″ ″ in the next beam compartment and is integrated into the concrete there in a known manner by means of the downwardly directed bracket a. EMI2.1
