Description

  

  Stahlbewehrter     Holzbalken.       Gegenstand der Erfindung bildet ein stahl  bewehrter Holzbalken. Die Erfindung besteht  darin, dass die Bewehrung zur Aufnahme der  Zugspannung dienende Rundstähle aufweist,  welche an ihren Enden rechtwinklig abge  bogene Spitzen aufweisen, die in den Holz  balken eingeschlagen sind, wobei noch in Ab  ständen am Balken befestigte Eisenschnallen  zum Halten der Stähle vorgesehen sind. Die       Wirkung    der Bewehrung ist also mit jener  von Stahlbeton vergleichbar.  



  Die Berechnung derartig bewehrter Holz  balken muss ähnlich dem Rechnungsverfahren  für auf Biegung beanspruchten Stahlbeton er  folgen. Die erforderlichen Annahmen hierzu  (Verhältnis der     Elastizitätszahlen    und der  gleichen) müssen auf Grund von Versuchen  bestimmt werden.  



  Der Vorteil eines solcherart bewehrten  Holzbalkens liegt vor allem darin, dass an dem  Balken selbst keinerlei Bearbeitung erforder  lich ist und die Bewehrung mit einfachen  Mitteln sogar am Bau selbst hergestellt wer  den kann.  



  In beiliegender Zeichnung ist eine Aus  führungsform des Erfindungsgegenstandes  veranschaulicht. Es zeigt:         Fig.    1 drei zur Bewehrung vorgearbeitete  Randstähle und Eisenschnallen zu deren Be  festigung,       Fig.    2 einen Querschnitt durch einen be  wehrten Balken,       Fig.    3 eine Seitenansicht eines bewehrten  Balkens.  



  Der dargestellte, einen rechteckigen Quer  schnitt aufweisende Holzbalken a weist an  seiner Unterseite eine Bewehrung b auf, wel  che aus Rundstählen besteht, die an beiden  Enden umgebogen und zu Spitzen d     ausge-          schmiedet    sind, die in den Holzbalken einge  schlagen sind. Die Rundstähle sind ferner  mittels Schnallen c, die in Abständen von  etwa 1,50 m voneinander am Balken mit  Nägeln e festgenagelt sind, am Balken befe  stigt.



  Steel-reinforced wooden beam. The invention forms a steel-reinforced wooden beam. The invention consists in that the reinforcement for absorbing the tensile stress has round steel bars which have bent tips at their ends at right angles, which are hammered into the wooden beams, with iron buckles attached to the beams at intervals to hold the steels. The effect of the reinforcement is therefore comparable to that of reinforced concrete.



  The calculation of wooden beams reinforced in this way must be carried out in a similar way to the calculation method for reinforced concrete subjected to bending. The necessary assumptions for this (ratio of elasticity numbers and the like) must be determined on the basis of tests.



  The main advantage of such a reinforced wooden beam is that no processing whatsoever is required on the beam itself and the reinforcement can even be produced on the building itself using simple means.



  In the accompanying drawing, an embodiment of the subject invention is illustrated. It shows: Fig. 1 three pre-machined edge steels and iron buckles for their attachment, Fig. 2 is a cross section through a be reinforced beam, Fig. 3 is a side view of a reinforced beam.



  The illustrated, a rectangular cross-section having wooden beam a has on its underside a reinforcement b, wel che consists of round steel, which are bent at both ends and forged into points d that are hammered into the wooden beam. The round bars are also fastened to the beam by means of buckles c, which are nailed to the beam with nails e at intervals of about 1.50 m from one another.
