Description

  

  Schalldämpfende Auskleidung eines Raumes    Die Erfindung bezieht sich auf eine schall  dämpfende Auskleidung eines Raumes, ins  besondere für     Düsentriebwerksprüfstände.     



  Bisher verwendete man bei derartigen       Auskleidungen    beispielsweise ein schall  schluckendes Material, welches mittels     geloeh-          ter    Blechplatten an der Wand festgehalten  wurde. In     Düsentriebwerksprüfständen    und  ähnlichen Räumen treten jedoch erhebliche  thermische und korrosive Belastungen auf,  welche zu einer raschen Zerstörung der     ge-          loeliten    Blechplatten führten.

   Die Erfindung       beseitigt    die geschilderte Schwierigkeit und ist  dadurch gekennzeichnet, dass an der Wand  des Raumes mit Abstand     voneinander    Balken       befestigt    sind, welche zwischen sich, im     Ab-          #;aand    von der Wand, eine aus gelochten Stei  nen     bestehende        Ausfachung    tragen, und     dass     der Zwischenraum zwischen dieser     Ausfa-          chung    und der Wand mit schallabsorbieren  dem Material ausgefüttert ist.  



  Eine besonders zweckmässige, stabile und  doch billige Ausführung ergibt sich, wenn die  Balken aus Beton bestehen und um in die  Wand eingelassene Halter gegossen sind.  



  Als schallabsorbierendes Material kann       beispielsweise    Mineralwolle verwendet werden,       gegebenenfalls    in der handelsüblichen Form  von vorgefertigten Matten.  



  Ein Ausführungsbeispiel der Erfindung  wird an Hand der Zeichnung näher erläutert.  in welcher in     Fig.    1 die Vorderansicht und  in Fis. 2 ein Schnitt durch einen Teil einer  erfindungsgemässen Auskleidung gezeigt. ist.  



  Um in die Wand 2 des Raumes einge  lassene Halter 1 sind Betonbalken 3 gegossen,         ;velche    gegebenenfalls durch Armierungen 4  versteift sein können. Nachdem der Beton fest  geworden ist, kann das     schallsehluckende    Ma  terial 5 in Form von loser     Mineralwolle,        Mine-          ralwollmatten,    Platten aus mineralischen  Stoffen, beispielsweise Asbest oder     derglei-          ehen,    an die Wand 2 gelegt werden. Davor.       -wird    nun die Schicht 6 von gelochten Steinen  befestigt. Als Steine können beispielsweise  handelsübliche gelochte Backsteine oder ge  lochte Zementsteine benutzt werden.



  Sound-absorbing lining of a room The invention relates to a sound-absorbing lining of a room, in particular for jet engine test stands.



  So far, for example, a sound-absorbing material has been used in such linings, which was fixed to the wall by means of perforated sheet metal plates. In jet engine test stands and similar rooms, however, considerable thermal and corrosive loads occur, which led to the rapid destruction of the gelatinized sheet metal plates.

   The invention eliminates the described difficulty and is characterized in that beams are attached to the wall of the room at a distance from one another, which between them, at a distance from the wall, carry an infill made of perforated stones and that the The space between this recess and the wall is lined with sound-absorbing material.



  A particularly useful, stable and yet cheap design is obtained when the beams are made of concrete and are cast around holders embedded in the wall.



  Mineral wool, for example, can be used as the sound-absorbing material, possibly in the commercially available form of prefabricated mats.



  An embodiment of the invention is explained in more detail with reference to the drawing. in which in Fig. 1 the front view and in Fis. 2 shows a section through part of a lining according to the invention. is.



  Concrete beams 3 are cast around the holder 1 let into the wall 2 of the room, and if necessary they can be stiffened by reinforcements 4. After the concrete has set, the sound-absorbing material 5 can be placed on the wall 2 in the form of loose mineral wool, mineral wool mats, panels made of mineral materials, for example asbestos or the like. Before. - Layer 6 is now attached by perforated stones. Commercially available perforated bricks or perforated cement stones, for example, can be used as stones.
