Schalldämpfender Schichtstoff.Sound absorbing laminate.

Der Betrieb einer Pfahlramme in Wohnbereichen ist infolge des von dieser erzeugten betäubenden Lärms ebenso ein Öffentliches Ärgernis wie eine Notwendigkeit. Dies trifft besonders für Explosionsrammen bzw. Brennkraft-Handrammen zu, die für schwere Arbeit verwendet werden. Es wurde versucht, diese Belästigung dadurch zu mildern, daß die Ramme und der Pfahl von einem Schaft umgeben werden, der mit einem schalldämpfenden Material ausgekleidet ist. Als schalldämpfendes Material wurden mehrere Schichtstoffe vorgeschlagen, beispielsweise Kombinationen aus einer Stahlplatte und Polyurethanschaum.Operating a post driver in residential areas is as much a public nuisance as it is a necessity due to the deafening noise it generates. This is especially true for explosion rams or internal combustion hand rams that are used for heavy work. Attempts have been made to alleviate this nuisance in that the ram and the pile are surrounded by a shaft which is lined with a sound-absorbing material. Several laminates have been proposed as sound-absorbing material, for example combinations of a steel plate and polyurethane foam.

409884/0925409884/0925

Es wurde festgestellt, daß für die vorerwähnte schwere Arbeit diese Schichtstoffe noch viel zu wünschen übrig lassen. Erstens hielt der Kunststoff den hohen Temperaturen nicht stand, die in dem Schalldämpfungsschaft durch das schwere Gerät erzeugt wurden, und zweitens war die Geräuschdämpfungswirkung nicht ganz ausreichend.It was found that these laminates left much to be desired for the aforementioned heavy work permit. First, the plastic did not withstand the high temperatures in the silencer shaft were generated by the heavy equipment, and secondly, the noise suppressing effect was not quite sufficient.

Durch die Erfindung wird ein Schichtstoff vorgeschlagen, der eine optimale Wirkung gibt, widerstandsfähig gegen hohen Temperaturen und Stöße ist und eine sehr gute Schalldämpfung ergibt. Der erfindungsgemäße Schichtstoff ist an einer Aussenflache mit einer feinmaschigen Metalldrahtgaze, z.B. Kupfergaze mit 15 - 25, vorzugsweise 20, Drähten je Zentimeter, wobei die Dicke jedes Drahtes zwischen 0,15 und 0,40 mm ist und vorzugsweise 0,30 mm beträgt. Diese Gaze dient, wenn sie auf die dem Geräusch und der Wärme zugekehrte Seite aufgebracht ist, dazu, die Wärme der Abgase der Pfahlramme zu leiten und abzuleiten, um eine örtliche Überhitzung zu verhindern. Drahtgaze der erwähnten Art ist, was die Schalldämpfungseigenschaften betrifft, besser geeignet als Blech. Das letztgenannte Material kann den Schall durch mehrfache Reflexion zwischen den Innenwänden des Schftes sowie längs des Metalls selbst zur Aussenseite des Schaftes (an seinem oberen und an seinem unteren Ende) wesentlich besser leiten als die erfindungsgemäß verwendete Drahtgaze.The invention proposes a laminate which gives an optimal effect and is resistant to high temperatures and shocks and results in very good sound absorption. The laminate according to the invention is on an outer surface with a fine-meshed metal wire gauze, e.g. copper gauze with 15-25, preferably 20, wires per centimeter, the thickness of each wire is between 0.15 and 0.40 mm and is preferably 0.30 mm. This gauze is used when responding to the sound and the side facing the heat is applied to conduct and dissipate the heat of the pile driver's exhaust gases, to prevent local overheating. Wire gauze of the type mentioned is what the soundproofing properties concerns, more suitable than sheet metal. The latter material can generate sound through multiple reflections between the inner walls of the shaft and along the metal itself to the outside of the shaft (on its upper and lower end) much better than the wire gauze used according to the invention.

Gemäß einer bevorzugten Ausführungsform der Erfindung wird eine weitere Verbesserung durch die Verwendung einer verhältnismässig dicken "Decke" aus geräuschdämpfendem Material, wie lose gepackte Glasfaser oder Mineralfaser, und einer dünneren Lage aus hochdichtem flexiblemAccording to a preferred embodiment of the invention, there is a further improvement through the use a relatively thick "blanket" made of sound-absorbing Material, such as loosely packed fiberglass or mineral fiber, and a thinner layer of high density flexible

409884/0925409884/0925

Material, Beispielsweise kann eine Glasfaserdecke von 5' - 10 cm und vorzugsweise 7 cm Dicke verwendet werden und die dünnere Lage besteht vorzugsweise aus einer Folie aus Gummi oder Kunststoff mit einer Füllung aus Bleipartikeln. Diese dünnere. Lage dient dazu, helle Geräusche zu dämpfen, die durch die erwähnte Dicke hindurehtreten können» Beispielsweise kann eine Gummioder Vinylkunststoff-Folie mit einer Dicke von 0,5 bis 1,5 mm und vorzugsweise von einem Millimeter mit einer Bleipulverfüllung und einem spezifischen Gewicht vonMaterial, for example, a fiberglass ceiling can be made of 5 '- 10 cm and preferably 7 cm thick can be used and the thinner layer is preferably made of a sheet of rubber or plastic with a filling Lead particles. This thinner one. Layer serves to attenuate bright noises that come through the thickness mentioned can »For example, a rubber or vinyl plastic film with a thickness of 0.5 to 1.5 mm and preferably one millimeter with a lead powder filling and a specific weight of

2,5 - 5 g je cm und vorzugsweise von etwa 3,5 g/cm verwendet werden. Das Bleipulver kann der Folie durch eine gleichmässige Verteilung desselben in dem Material der Folie während der Herstellung der letzteren einverleibt werden. Zur Erhöhung der Festigkeit kann die Folie mit einer oder mehreren Leinwandlagen fest verbunden werden. Vorzugsweise muß Sorge dafür getragen werden, daß die Decke aus geräuschdämpfendem Material nicht von Wasser oder öl durchdrungen wird, da ihre Wirksamkeit dadurch nachteilig beeinflußt werden würde. Um dies zu vermeiden, kann die Decke mit einer Schutzfläche versehen werden. Dies kann dadurch geschehen, daß die Decke beispielsweise mit einem faltbaren flächenhaflen Material, wie ein leichtes Leinwandgewebe (canvas cloth), das durch Imprägnieren unbrennbar gemacht worden ist, beschichtet oder "umhüllt" wird. Eine "Teflon"-Folie kann ebenfalls verwendet werden oder ein Glasfasertuch, das mit Teflon oder einem anderen hitzebeständigen Kunststoff beschichtet ist, und diese Folie bzw. dieses Tuch kann auf nur einen Teil der Fläche der Decke aufgebracht werden, nämlich nur auf diejenige Fläche, von der aus öl oder Wasser in die Decke eindringen kann. Ferner können die Flächen der Decke selbst mit einer Beschichtung aus2.5-5 g per cm and preferably about 3.5 g / cm can be used. The lead powder can pass through the foil a uniform distribution of the same in the material of the film incorporated during the manufacture of the latter will. To increase the strength, the film can be firmly connected to one or more layers of canvas will. It is preferable to ensure that the ceiling is made of sound-absorbing material is not penetrated by water or oil, since their effectiveness would be adversely affected. To avoid this, the ceiling can be provided with a protective surface. This can be done in that the ceiling, for example, with a foldable flat handle Material, such as a light canvas cloth, which has been made incombustible by impregnation, is coated or "enveloped". A "Teflon" film Can also be used or a fiberglass cloth covered with Teflon or other heat resistant plastic is coated, and this film or this cloth can be applied to only part of the surface of the ceiling only on the surface from which oil or water can penetrate the ceiling. Furthermore can the surfaces of the ceiling itself with a coating

einem - vorzugsweise hitzebeständigen - wasser- und ölbeständigen Kunststoff behandelt werden.a - preferably heat-resistant - water and oil-resistant plastic.

Um dem Schichtstoff Steifigkeit und Robustheit bzw. Stabilität zu ve&eihen, kann dieser mit einer Lage aus einer ziemlich schweren Metallgaze verwendet werden. Beispielsweise kann eine zinkbeschichtete Stahldrahtgaze mit einer Maschenweite von etwa 4 mm und einer Drahtdicke von etwa 1 mm verwendet werden. Zweckmässig wird diese Drahtgaze an der am weitesten nach innen liegenden Seite des Schichtstoffes angeordnet, d.h. auf derjenigen Seite, von der das Geräusch kommt, so daß die vorerwähnte feinmaschige wärmeableitende Gaze die zweite Lage bildet. Die gröbetce Gaze wirkt mit der feineren zur Wärmeableitung zusammen. In order to give the laminate rigidity and robustness or stability, it can be provided with a layer made of a fairly heavy metal gauze can be used. For example, a zinc-coated steel wire gauze with a mesh size of about 4 mm and a wire thickness of about 1 mm can be used. This becomes useful Wire gauze arranged on the furthest inward side of the laminate, i.e. on the side from which the noise comes, so that the aforementioned fine-meshed heat-dissipating gauze forms the second layer. the coarser gauze works together with the finer gauze to dissipate heat.

Ein bevorzugter Aufbau des Schichtstoffes besteht daher aus einer schweren Metallgaze an der Innenseite, an der das Geräusch entsteht, der feinen Metallgaze, dann der dicken Glasfaser- oder anderen Decke, die gegebenenfalls teilweise oder ganz von einer geeigneten Folie bedeckt oder umhüllt sein kann, und dann aus der Gummifolie od. dgl. ait Bleipulver.A preferred structure of the laminate therefore consists of a heavy metal gauze on the inside on which the noise occurs, the fine metal gauze, then the thick glass fiber or other cover, which can optionally be partially or completely covered or enveloped by a suitable film, and then from the rubber sheet or the like with lead powder.

Der erfindungsgemäße Schichtstoff kann in Form von vorgefertigten Platten aus zusammenhaftenden Lagen hergestellt und aufgebracht werden, welche ausreichend aneinander haften, um den Transport, die Handhabung und den Einbau leicht zu machen, oder er kann innerhalb des Rahmens an der Stelle, an welcher er verwendet werden soll, oder in einem Werk aufgebaut werden.The laminate according to the invention can be produced in the form of prefabricated panels from layers that adhere together and applied, which adhere sufficiently to each other to make transport, handling and installation easy to make, or it can be inside the frame at the point where it is intended to be used, or in a work to be built.

Teils eines erfindungsgemäßen Schichtstoffes und eines Rahmens, an dem er angebracht werden soll, beispielsweise dargestellt.Part of a laminate according to the invention and one Frame to which it is to be attached, shown for example.

Ein offener Rahmen, beispielsweise ein offenes Gehäuse aus Stahlträgern ist um eine Geräuschquelle, beispielsweise um eine Pfahlramme, herum angeordnet, die nicht gezeigt ist, deren Stellung jedoch mit drei bezeichnet ist. Dieser Rahmen kann aus einigen ziemlich schweren vertikalen Trägern und leichteren horizontalen Trägern 1 bestehen, zwischen denen geneigte und vertikale Träger 2 angeordnet sind, welche die schweren Träger zur Bildung eines starren Rahmens verbinden, der leicht zusammengebaut und zerlegt, werden kann und/oder Teile aufweisen kann, schwenkbar an einem Pfahlrammengerüst gelagert sind, um das öffnen und Schliessen des Gehäuses zu ermöglichen, welches die Geräuschquelle völlig umgibt, jedoch oben und unten offen ist.An open frame, for example an open housing made of steel beams, is around a source of noise, for example around a pile driver, which is not shown but whose position is indicated by three. This frame can consist of some fairly heavy vertical beams and lighter horizontal beams 1, between which inclined and vertical beams 2 are arranged, which the heavy beams to form a rigid Connect frame that is easily assembled and disassembled, can be and / or can have parts, are pivotably mounted on a pile driver frame to open and Closing the housing to allow the source of the noise completely surrounds, but is open at the top and bottom.

An diesem Rahmen bzw, Gehäuse ist ein Schichtstoff U befestigt. Der Rahmen kann beispielsweise ein zylindrisches oder polygonales Gehäuse bilden, dessen vertikale Achse sich mit dem in den Boden einzutreibenden Pfahl in Ausfluchtung befindet, und der Schichtstoff 4 wird an diesem in Form von ebenen oder teilzylindrisch gekrümmten Platten angebracht werden, die vom Rahmen durch nachstehend näher beschriebene geeignete Mittel getragen werden.A laminate U is attached to this frame or housing. The frame can for example form a cylindrical or polygonal housing, the vertical axis of which is in alignment with the pile to be driven into the ground and the laminate 4 is attached to it in Form of flat or part-cylindrical curved plates are attached to the frame by below in more detail appropriate means described are carried.

Die Schichtstoffρlatten k an der Innenseite des Gehäuses weist eine schwere Metallgaze 5 auf, die dazu dient, dem Schichtstoff Steifigkeit und Robustheit bzw. Stabilität zu verleihen, beispielsweise eine Gaze aus zinkbeschichtetem Stahldraht mit Maschen von etwa ·+ mm und einer Drahtstärke von 1 mm.The laminate plates k on the inside of the housing has a heavy metal gauze 5, which is used to give the laminate rigidity and robustness or stability, for example a gauze made of zinc-coated steel wire with meshes of about + mm and a wire thickness of 1 mm.

Mit 6 ist eine Lage aus einer feinmaschigen Kupferdrahtgaze bezeichnet und mit 7 ein leichtes Leinwandtuch, welches bei dem dargestellten Ausführungsbexspiel die Decke 8 völlig umgibt. Diese Decke besteht aus lose gepackten hitzebeständigen Fasern, wie erwähnt. Die Decke ist an ihrer Aussenflache, d.h. an ihrer der Geräuschquelle 3 abgekehrten Fläche mit einer Gummifolie 9 bedeckt, welche über ihre ganze Oberfläche mit Bleipulver beispielsweise dadurch versehen worden ist, daß Bleipulver mit dem Gummi- oder Kunststoffmaterial gründlich vermischt wurde. Durch dieses Pulver wird der Folie das notwendige spezifische Gewicht und damit die notwendige Massenträgheit zur Dämpfung heller Geräusche gegeben. Das Tuch 7 kann zwischen dem Tuch 8 und der schweren Lage 9 vorgesehen werden, statt daß es diese auch umgibt.With 6 a layer of a fine-meshed copper wire gauze is referred to and with 7 a light canvas, which completely surrounds the ceiling 8 in the illustrated Ausführungsbexspiel. This blanket is made of loose packed refractory fibers as mentioned. The ceiling is on its outer surface, i.e. at its source of noise 3 remote surface covered with a rubber sheet 9, which over its entire surface with lead powder has been provided, for example, by thoroughly mixing lead powder with the rubber or plastic material was mixed. This powder gives the film the necessary specific weight and thus the necessary Inertia given to dampen bright noises. The cloth 7 can be between the cloth 8 and the heavy Layer 9 can be provided instead of surrounding it.

Der Schichtstoff 4 kann mit allen Lagen 5, 6, 7, 8 und 9 als zusammenhängender Körper einen Verbund bilden, der handhabbar und transportfähig ist und mit dem Rahmen durch geeignete Halterungen, Zusammenbauschienen od. dgl., in einer dem Fachmann an sich bekannten Weise verbunden werden, beispielsweise um wärmeisolierende Platten an den Wänden von Kühlräumen in Schiffen und Kühlhäusern anzubringen,The laminate 4 can with all layers 5, 6, 7, 8 and 9 as a coherent body form a composite that is manageable and transportable and with the frame by suitable holders, assembly rails or the like, connected in a manner known per se to the person skilled in the art be, for example, heat-insulating panels on the walls of cold rooms in ships and cold stores to attach

Ferner kann der Schichtstoff am Rahmen dadurch befestigt werden, daß die schwere Gaze 5 und die feine Gaze 6 mit den Trägern des Rahmens durch Punktschweissen fest verbunden werden oder dadurch, daß die erwähnten Lagen mit diesen vernietet werden, wie schematisch durch wenige kleine Nieten 10 dargestellt, und dadurch, daß die Decke mit der Guaraiifolie 9 und mit dem Leinwandtuch 7 durch flexible Metallbügel 11 umhüllt wird, die sich zwischen den vertikalen Trägern des Rahmens erstrecken, und Flüge1-Further, the laminate can be attached to the frame by the heavy gauze 5 and the fine gauze 6 with firmly connected to the girders of the frame by spot welding be or by the fact that the layers mentioned are riveted to them, as schematically by a few small rivets 10 shown, and in that the ceiling with the Guaraiifolie 9 and with the canvas 7 through flexible metal bracket 11 is enveloped, which extend between the vertical beams of the frame, and flights1-

muttern 12 auf Bolzen 13, die an den Rahmenträgern 1 befestigt sind, und dadurch die Teile 7, 8 und 9 gegen die Gazeschichten 5,6 drücken, ohne jedoch die Decke wesentlich zusammenzudrücken.nuts 12 on bolts 13, which are attached to the frame girders 1, and thereby parts 7, 8 and 9 press against the gauze layers 5,6 without, however, significantly compressing the cover.

Das durch Rahmen und Schichtstoffplatten gebildete Gehäuse kann oben und unten ganz oder teilweise offen sein, damit Rohre hindurchgeführt werden können, die zur Pfahlramme od. dgl. und von dieser weg führen, damit die Abgase abgeleitet werden können und Raum für denDurchtritt des in den Boden einzutreibenden Pfahls besteht. Das Gehäuse kann sehr viel langer als die eigentliche Pfahlramme sein, so daß das am oberen und am unteren Ende des Gehäuses austretende Geräusch bereits wesentlich gedämpft oder absorbiert worden ist, bevor es diese erreicht.The housing formed by the frame and laminate panels can be completely or partially open at the top and bottom so that pipes can be passed through that lead to the pile driver or the like and away from it, so that the exhaust gases can be discharged and space for the penetration of the fuel to be driven into the ground Stake. The housing can be much longer than the actual pile driver, so that at the top and noise emerging from the lower end of the housing has already been substantially attenuated or absorbed, before it reaches this.
