  Ziegelhohlbalken (Hourdy). 



   Den im   Deckenbau     verwendeten Ziege) hohlbalken,   den sogenannten Hourdys, haftet der   Ubelatand   an, dass dieselben (bei gesehener Tragfähigkeit) über eine gewisse verhältnismässig geringe Länge und Höhe hinaus nicht hergestellt werden können, weil sonst das aus praktischen Rücksichten - wie dem Transport und der handbabung durch den Arbeiter auf dem   Bauplatz-   noch zulässige   Maximalgewicht überschritten werden würde.   Die Erfindung hilft nun diesem 
 EMI1.1 
   eigentümlichen   Eigenschaft ausgeht, welche darin besteht. dass die Zugfestigkeit desselben bloss einen Bruchteil der Druckfestigkeit ausmacht.

   Diese neue Querschnittsgestaltung kennzeichnet sich   gegenüber   dem Querschnitt der bekannten Ziegelhohlbalken und überhaupt aller, auch der Eisenträger des Hochbaues, dadurch aus. dass der Ober-und Untergurt nicht   mehr gleich gross   sind, dass vielmehr der Untergurt, die Basis, verbreitert oder verstärkt ist. 



   Nun sind wohl Hourdys bekannt, bei welchen die Basis, sei es durch Schrägstellung der Seitenwände oder durch Flanschen, verbreitert ist. Diese Verbreiterung wird jedoch   lediglich zu dem Zweck   
 EMI1.2 
 wobei gegebenenfalls der Obergurt überdies verschwächt ist, so   dass Material zur Vergrösserung   des Hourdys in   der Länge oder Höhe bei gleicher Tragfähigkeit   ohne Überschreitung des Maximal   gewichtes gewonnen wird.

   Die grössere   Länge aber, die der neue Hourdy gegenäber einem bisherigen Hourdy gleicher Tragfähigkeit aufweist, schafft den Vorteil, dass der   Abstand zwischen   zwei   Deckentraversen (Eisenträgern) vergrössert,   dadurch die Zahl derselben verringert wird.   Der Vorteil der grösseren Höhe hinwider ist   darin gelegen, dass die Höhe der über den   Hourdv   einzubringenden Aufschüttung vermindert, damit aber die tote Belastung herabgesetzt wird. wodurch schwächere Deekentraversen verwendet werden   können.

  Brick hollow beam (Hourdy).



   The hollow goat beams used in ceiling construction, the so-called hourdys, are adhered to by the Ubelatand that they (given the load-bearing capacity) cannot be made beyond a certain relatively short length and height, because otherwise this is for practical reasons - such as transport and handbabung by the worker on the construction site - the maximum weight allowed would be exceeded. The invention now helps this
 EMI1.1
   peculiar property that consists in it. that the tensile strength of the same is only a fraction of the compressive strength.

   This new cross-sectional design is distinguished from the cross-section of the known hollow brick beams and all of them, including the iron girders of building construction. that the upper and lower chords are no longer the same size, that rather the lower chord, the base, is widened or reinforced.



   Hourdys are now well known in which the base is widened, be it by inclining the side walls or by flanges. However, this broadening is only for the purpose
 EMI1.2
 the top chord may also be weakened, so that material for enlarging the hourdy in length or height is obtained with the same load-bearing capacity without exceeding the maximum weight.

   However, the greater length that the new Hourdy has compared to a previous Hourdy with the same load-bearing capacity creates the advantage that the distance between two ceiling cross members (iron girders) is increased, thereby reducing the number of them. On the other hand, the advantage of the greater height is that the height of the embankment to be brought in above the Hourdv is reduced, but the dead load is thus reduced. so that weaker deeke trusses can be used

   Ribs lead from the side parts to the base, which send two ribs to the apex and reinforced in the lower part. are. In Fig. 6 a blanket assembled from the new Hourdys is illustrated. The one hourdy (see the halves on the ends)
