  Hohlstein zur Herstellung von Steinbetoneisendecken. 



   Es sind bereits Hohlsteine für Decken mit einer lotrechten Mittelrippe und beiderseits derselben angeordneten bogenförmigen Rippen bekannt, welche sich vom Steinscheitel zum Fusspunkt der Seitenwand erstrecken. Demgegenüber besteht die Erfindung darin, dass geradlinige, schräge Seitenrippen dicht unterhalb des Steinscheitels von der Mittelrippe abzweigen und sich gegen Hüften der   Steinseitenwände   stützen.   Hindurch   wird der Vorteil erreicht. dass die Abstützung der Steinseitenwände und die Druckverteilung im Stein günstiger wird. Dadurch, dass die Seitenrippen nicht genau im Scheitel angeschlossen sind, wird erreicht, dass die Knicklänge der auf Druck beanspruchten Mittelrippe kleiner wird. 



   Die Zeichnung, welche den Erfindungsgegenstand beispielsweise darstellt, zeigt in Fig. 1 den Querschnitt durch eine Reihe von Hohlsteinen in Verbindung mit der aufgebrachten Beton- 
 EMI1.1 
 wird der Vorteil erreicht, dass die Abstützung der   Steinseitenwändp   und die Druckverteilung im Stein günstiger wird. 



   Die am Fusse der beiden Längsseiten mit je einer Einkerbung d versehenen Hohlsteine   ut   werden aneinandergereiht und die verbleibenden Zwischenräume in bekannter Weise mit einer 
 EMI1.2 
 welche mittels Bügel i miteinander verbunden sind.

  Hollow stone for the production of stone concrete iron ceilings.



   There are already known hollow stones for ceilings with a vertical central rib and arc-shaped ribs arranged on both sides of the same, which extend from the stone apex to the base of the side wall. In contrast, the invention consists in that straight, inclined side ribs branch off from the central rib just below the stone apex and are supported against the hips of the stone side walls. This achieves the advantage. that the support of the stone side walls and the pressure distribution in the stone is more favorable. The fact that the side ribs are not connected exactly at the apex ensures that the buckling length of the center rib, which is subjected to compression, is reduced.



   The drawing, which represents the subject of the invention, for example, shows in Fig. 1 the cross section through a series of hollow stones in connection with the applied concrete
 EMI1.1
 the advantage is achieved that the support of the stone side walls and the pressure distribution in the stone is more favorable.



   The hollow stones ut, each provided with a notch d at the foot of the two long sides, are strung together and the remaining spaces in a known manner with a
 EMI1.2
 which are connected to one another by means of bracket i.
