Wie dargestellt, bilden eine Vielzahl von Schalldämmelementen 10 eine schalldämmende Schicht in Form einer Wand, einer Decke eines Bodens od. dgl.« Diese Elemente bestehen aus schalldämmendera Material 12, vie Fiberglas od. dgl,. Zwischen zwei gegenüberliegenden und das schalldämmende Material umhüllenden Wandungen 13, 15, die aus geeignetem Material, beispielsweise aus galvanisiertem Metall bestehen.As shown, form a variety of soundproofing elements 10 a sound-absorbing layer in the form of a wall, one Ceiling of a floor or the like. «These elements consist of sound-absorbing material 12, such as fiberglass or the like. Between two opposite walls 13, 15 enveloping the sound-absorbing material, which are made of suitable Material, for example made of galvanized metal.
Jede der Wandungen 13 hat eine Anlagefläche 14, von der aus sich an jedem Ende Flanken 18 nach innen erstrecken, von denen wiederum Flansche 20 horizontal nach außen abgewinkelt sind und zwar in einem Bereich, der etwa in der mittleren Teilungsebene der Schalldämmelemente 10 liegt. Die äußere Abdeckung 15 hat eine Außenfläche 16 mit an beiden Enden abgewinkelten Flanken 22, die gegen die Flanken 18 der Verkleidung 14 gerichtet sind. Auch die Außenverkleidung weist horizontal verlaufende Flansche 24 auf, so daß bei Zusammenstellung die Flanschen 20 und 24 miteinander in parallelem Kontakt stehen.Each of the walls 13 has a contact surface 14 from which flanks 18 extend inwardly at each end, of which in turn flanges 20 angled horizontally outward are in an area which lies approximately in the middle dividing plane of the sound insulation elements 10. The outer Cover 15 has an outer surface 16 with at both ends angled flanks 22 against the flanks 18 of the Cladding 14 are directed. The outer cladding also has horizontally extending flanges 24 so that at Composition the flanges 20 and 24 are in parallel contact with one another.

Falls drei oder mehr Schalldämmelemente 10 zu verbinden sind, so werden beide Enden jedes Elementes mit benachbarten Planschen versehen.If three or more soundproofing elements 10 are to be connected, so both ends of each element are provided with adjacent paddles.
Wenn eine Vielzahl von Schalldämmelementen 10 in Form einer Wandung od. dgl. vorzusehen sind, so werden sie fest durch U-förmige Verbinder 38 zusammengehalten, die einen Quersteg 30 aufweisen, der vorzugsweise so angeordnet ist, daß er mit der Außenfläche 16 der Elemente in einer Ebene liegt. An den Quersteg 30 schließen sich Schenkelflächen 32 und 34 an.If a plurality of sound insulation elements 10 or the like in the form of a wall are to be provided, they will be firmly through U-shaped connector 38 held together, which has a transverse web 30, which is preferably arranged so that it lies in one plane with the outer surface 16 of the elements. Leg surfaces 32 and 34 adjoin the crosspiece 30.
Die Schenkelfläche , 32 in einem kurzen, abgewinkelten Flansch 36, der den Flansch 24 berührt und die Schenkelfläche 34 endet in gleicher Weise mit einem Flansch 40, der den anderen Flansch 24 berührt. Der Quersteg 30 ist mit einem Loch 39 versehen. Ein anderer U-förmiger Verbinder 42 hat einen Quersteg 44, der mit der Ebene der Außenverkleidung 14 fluchtet. Von innen ist gegen diesen Quersteg eine Büchse 46 geschweißt. Zwei Schenkelflächen 48 und 52 schließen sich an den Quersteg 44 an und enden in Flanschen 50 und 54, die nach innen abgewinkelt sind, ähnlich den Flanschen 36 und 40.The leg surface, 32 in a short, angled flange 36 that contacts the flange 24 and the leg surface 34 ends in the same way with a flange 40 which contacts the other flange 24. The crosspiece 30 is with a hole 39 is provided. Another U-shaped connector 42 has a transverse web 44 that coincides with the plane of the outer panel 14 aligns. A bushing 46 is welded from the inside against this crosspiece. Two leg surfaces 48 and 52 adjoin the crosspiece 44 and terminate in flanges 50 and 54 which are angled inward, similar to the Flanges 36 and 40.

Ein Schraubbolzen 56 ist in das Loch 39 gesteckt und in die Büchse 46 eingeschraubt. Dadurch können die Verbinder 38 und 42 gegeneinander gezogen werden, wenn der Bolzen 56 in die Büchse 46 eingeschraubt wird, wobei die Plansche 36 und fest gejpn die Flansche 20 und 24 gezogen werden. In gleicher Weise werden die Flansche 50 und 54 fest gegen die Flansche und 24 der Außenwandung 13 gezogen. Bei der anderen Ausführungsform gem. Fig. 3 ist eine mit einer Gewindebohrung versehene Scheibe bzw. Leiste 60 vorgesehen, wobei ein Schraubbolzen 64 in die Gewindebohrung 62 eingeschraubt ist und über diese herausragt. Wenn der Schraubbolzen fest in die Leiste 60 eingeschraubt wird, so werden die Flansche 50 und 54 fest zusammengespannt und damit auch die Außenverkleidung 13 und 15. Unmittelbar unter der Leiste 60 ist komprimierte Glasfaser 66 angeordnet, die als Schalldämmmaterial dient. Bei der Ausführungsform gem. Fig. 4 ist ein im Querschnitt kleinerer u-förmiger Verbinder 70 vorgesehen, der innerhalb des u-förmigen Verbinders 42 angeordnet ist. Am Quersteg 72 des Verbinders 70 ist eine mit Innengewinde versehene Büchse 74 eingeschweißt. Zwischen diesen Verbindern 42 und 72 ist Schalldämmmaterial 76 angeordnet. Der Verbinder 70 ist mit Schenkelflächen 78 und 80 versehen,"die sich gegen die Flansche 50 und 54 abstützen* Bin Schraubbolzen 82 erstreckt sich vom Loch 39 aus in die mit Innengewinde versehene Büchse und beim Anziehen dieses Schraubbolzens wird der kleine Verbinder 72 gqpn die Flansche 50 und 54 verspannt, wodurch ebenfalls die gesamte Schalldämmanordnung bzw. deren _g_A screw bolt 56 is inserted into the hole 39 and screwed into the sleeve 46. This allows the connectors 38 and 42 to be pulled against each other when the bolt 56 is screwed into the sleeve 46, pulling the tabs 36 and, firmly connected, the flanges 20 and 24. In the same way, the flanges 50 and 54 are drawn firmly against the flanges 14 and 24 of the outer wall 13. In the other embodiment according to FIG. 3, a washer or bar 60 provided with a threaded hole is provided, a screw bolt 64 being screwed into the threaded hole 62 and protruding beyond it. When the screw bolt is screwed tightly into the strip 60, the flanges 50 and 54 are clamped tightly together and thus also the outer cladding 13 and 15. Compressed glass fiber 66 is arranged immediately below the strip 60 and serves as a soundproofing material. In the embodiment according to FIG. 4, a U-shaped connector 70 with a smaller cross-section is provided, which is arranged inside the U-shaped connector 42. An internally threaded bushing 74 is welded onto the crosspiece 72 of the connector 70. Soundproofing material 76 is arranged between these connectors 42 and 72. The connector 70 is provided with leg surfaces 78 and 80 which bear against the flanges 50 and 54. A bolt 82 extends from hole 39 into the internally threaded socket and as this bolt is tightened, the small connector 72 becomes the flanges 50 and 54 braced, whereby the entire sound insulation arrangement or its _g_

Elemente gegeneinander gezogen und befestigt werden. Durch die Einbringung von Glasfasern 12 zwischen die Stege 72 und 74 wird die ganze Verbindung ebenfalls zur Schalldämmf unkt ion mit herangezogen.Elements are pulled against each other and fastened. By introducing glass fibers 12 between the webs 72 and 74 the entire connection is also used for the sound insulation function.
Ein kompressibles Material 58, wie Gummi, Kunststoff od. dgl. können auf den Flanschen 50 und 54, wie aus Fig. 6 erkennbar, angeordnet werden, um die ganze Anordnung zusätzlich schalldichter zu machen.A compressible material 58, such as rubber, plastic or the like, can be applied to the flanges 50 and 54, as can be seen from FIG. be arranged in order to make the whole arrangement additionally soundproof.
Gem. Fig. 7 ist der kleinere Verbinder 70 mit Gewindebüchsen 86 versehen, die auf der Innenfläche seines Quersteges 72 aufgeschweißt sind, welche in gewünschter Distanz voneinander aufgebracht werden können. Die Ausführungsformen gem. Fig. 3 und 4 haben den Vorteil, daß sich auf den Außenflächen der Verbinder 42 keine Verfärbungen ergeben, da an diesen Verbindern keine Aufnahmeelemente für die Schraubbolzen zu schweißen sind. According to FIG. 7, the smaller connector 70 is provided with threaded bushings 86 which are positioned on the inner surface of its transverse web 72 are welded, which at the desired distance from each other can be applied. The embodiments according to. Fig. 3 and 4 have the advantage that on the outer surfaces the connector 42 does not result in discoloration, since no receiving elements for the screw bolts need to be welded on these connectors.
