Description

Schalldämm wand mit Vertikalpfosten und einer Vielzahl von Dämmelementen  Sound insulation wall with vertical posts and a variety of insulation elements
Die Erfindung betrifft eine Schalldämm wand mit Vertikalpfosten und einer Vielzahl von Dämmelementen der im Oberbegriff des Anspruchs 1 genannten Gattung. The invention relates to a sound-insulating wall with vertical posts and a plurality of insulating elements referred to in the preamble of claim 1 genus.
Schalldämmwände vorbekannter Bauform werden üblicherweise aus Vertikalpfosten aufgebaut, die in regelmäßigen Abständen, beispielsweise entlang einer Straße, einer Industrieanlage oder entlang eines Gleises aufgestellt werden und zwischen die plat- tenförmige Dämmelemente eingesetzt werden. Derartige Dämmelemente umfassen ein Blechgehäuse, insbesondere aus Aluminium, in dessen Innenraum eine Dämmeinlage gehalten ist. Soundproof walls of prior art design are usually constructed of vertical posts which are placed at regular intervals, for example along a road, an industrial plant or along a track and are inserted between the plate-shaped insulating elements. Such insulation elements comprise a sheet-metal housing, in particular of aluminum, in the interior of which an insulating insert is held.
An Gleisstrecken werden Schalldämmwände mit geringem Abstand zu den Gleisen aufgebaut. An Bahnstrecken, insbesondere an Hochgeschwindigkeits-Gleisstrecken treten an den Dämmelementen pulsierende Luftdrucklasten auf, die durch die Druckwellen vorbeifahrender Züge erzeugt werden. Um die daraus resultierenden mechanischen Lasten dauerhaft aufnehmen zu können, wurde in der DE 10 2007 034 134 AI vorgeschlagen, dass das Blechgehäuse einen quer zu seiner Längsachse liegenden Hohlquerschnitt aufweist und dass Umfangwände des Blechgehäuses durch mindestens ein bezogen auf diesen Hohlquerschnitt abgekantetes Blech gebildet sind. On track tracks sound insulation walls are built with a short distance to the tracks. On railway lines, especially on high-speed railway tracks occur on the insulation elements pulsating air pressure loads generated by the pressure waves passing trains. In order to be able to permanently absorb the mechanical loads resulting therefrom, DE 10 2007 034 134 A1 has proposed that the sheet metal housing have a hollow cross section lying transversely to its longitudinal axis and that peripheral walls of the sheet metal housing are formed by at least one sheet metal bent relative to this hollow cross section.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schalldämmwand der eingangs genannten Art zu schaffen, die kostengünstiger herstellbar ist. The present invention has for its object to provide a sound-absorbing wall of the type mentioned, which is less expensive to produce.
Diese Aufgabe wird durch eine Schalldämmwand der eingangs genannten Gattung mit den Merkmalen des Anspruchs 1 gelöst. Mit der vorliegenden Erfindung wird erreicht, dass gegenüber der bekannten Ausführung die endseitige Gestaltung der Dämmelemente einfacher und billiger ist, da weniger Einzelteile notwendig sind und Material sowie Montagekosten entfallen. Die Gestaltung der Lärmschutzelemente mit stirnseitig offenen Enden führt zu einer Verringerung der Schallausbreitung um die Kante des Lärmschutzelementes herum, weil dort kein Metall mehr vorhanden ist. Schall der das Metall zum Schwingen bringt wird also nicht mehr durch Metall um diese Kante weitergeleitet. Ein weiterer positiver Aspekt besteht darin, dass der Abstand von der Stirnseite des Dämmelements zum gegenüberliegenden Abschnitt des Vertikalpfostens zusätzlich zu einer Schallreduzierung führt, weil kein exakt definierter Schwingungsknoten für eine Schallwelle mehr vorhanden ist. This object is achieved by a sound insulating wall of the type mentioned with the features of claim 1. With the present invention it is achieved that over the known design, the end-side design of the insulating elements is easier and cheaper, since fewer items are necessary and material and installation costs omitted. The design of the noise protection elements with ends open at the ends leads to a reduction of the sound propagation around the edge of the noise protection element, because there is no more metal there. Sound that makes the metal vibrate is therefore no longer passed through metal around this edge. Another positive aspect is that the distance from the end face of the Dämmelements to the opposite portion of the vertical post in addition to a reduction in noise, because no exactly defined node for a sound wave is more available.
In weiterer Ausgestaltung der Erfindung sind der obere Halter und der untere Halter vorzugsweise Strangpressprofile aus Aluminium. Sie können als offene oder geschlossene Profile ausgebildet sein. Derartige Profile können auf einfache Weise in der gewünschten Form hergestellt werden und haben ein geringes Gewicht. Diese Bauteile werden bevorzugt ohne scharfe Kanten hergestellt, so dass die Gefahr von Verletzungen nicht gegeben ist. Zweckmäßigerweise weist der obere Halter bezogen auf den Querschnitt zwischen seitlichen Profilen einen Aufnahmeraum und über diesem einen trapezförmigen Abschnitt mit einer Zwischenwand auf. Vorzugsweise weist der untere Halter bezogen auf den Querschnitt zwischen seitlichen Profilen einen Aufnahmeraum und unter diesem eine Mittenwand auf, wobei in der Mittenwand eine Erhöhung zur Bildung seitlicher Kanäle vorgesehen ist. Alternativ hierzu ist es auch möglich, an der Mittenwand zum Aufnahmeraum gerichtete Stützen anzuordnen, zwischen denen Kanäle gebildet sind. Die Bildung der Kanäle hat den Vorteil, dass Feuchtigkeit, die sich am Dämmstoffkörper niederschlägt, nach unten abläuft und somit in die Kanäle gelangt und in diesen in Längsrichtung des Dämmelementes abgeführt wird. In a further embodiment of the invention, the upper holder and the lower holder are preferably extruded aluminum profiles. They can be designed as open or closed profiles. Such profiles can be easily manufactured in the desired shape and have a low weight. These components are preferably made without sharp edges, so that the risk of injury is not given. Conveniently, the upper holder with respect to the cross section between lateral profiles on a receiving space and on this a trapezoidal section with an intermediate wall. Preferably, the lower holder with respect to the cross section between lateral profiles a receiving space and under this a center wall, wherein in the middle wall an increase to the formation of lateral channels is provided. Alternatively, it is also possible to arrange on the center wall to the receiving space directed supports between which channels are formed. The formation of the channels has the advantage that moisture, which is reflected on the insulating body, runs down and thus enters the channels and is discharged in these in the longitudinal direction of the insulating element.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass am oberen Halter und/oder unteren Halter stirnseitig angeordnete Stopper vorgesehen sind, welche die Dämmelemente in ihrer Längsrichtung an den Vertikalpfosten abstützen. Dadurch wird sichergestellt, dass die Dämmelemente sich nicht in deren Längsrichtung verschieben. Zweckmäßigerweise weist der obere Halter und/oder untere Halter stirnseitige Öffnungen auf, in die ein Befestigungsabschnitt der Stopper einsteckbar ist. Dadurch werden keine zusätzlichen Befestigungsmittel erforderlich und die Montage vereinfacht. Bevorzugt ist die Öffnung zur Aufnahme des Befestigungsabschnitts in dem trapezförmigen Abschnitt des oberen Halters gebildet. According to an advantageous embodiment of the invention it is provided that provided on the upper holder and / or lower holder end-side stopper, which support the insulation elements in their longitudinal direction on the vertical posts. This ensures that the insulation elements do not move in their longitudinal direction. Conveniently, the upper holder and / or lower holder on the front side openings into which a fixing portion of the stopper can be inserted. This eliminates the need for additional fasteners and simplifies assembly. Preferably, the opening for receiving the attachment portion is formed in the trapezoidal portion of the upper holder.
Von Vorteil ist, wenn die Stopper aus einem EPDM bestehen. Zweckmäßigerweise sind die Stopper als ein im Wesentlichen T-förmiger oder L-förmiger Körper gestaltet, wodurch es möglich ist, den Stopper am Dämmelement zu befestigen, indem ein Schenkel des Körpers in eine der stirnseitigen Öffnungen des Halters eingesteckt ist. Die Stopper liegen vorzugsweise an einem Steg des Vertikalpfostens an. It is advantageous if the stoppers consist of an EPDM. Conveniently, the stoppers are designed as a substantially T-shaped or L-shaped body, whereby it is possible to attach the stopper to the insulating member by a leg of the body is inserted into one of the frontal openings of the holder. The stoppers are preferably applied to a web of the vertical post.
Die Vertikalpfosten weisen gegenüberliegende Schenkel auf, zwischen denen die Enden der Dämmelemente aufgenommen und gegen diese mittels Koppelelementen abgestützt sind. Eine solche Anordnung hat den Vorteil, dass die Koppelelemente in jedem Belastungszustand (Vollkompression und Vollentlastung) stets Kontakt zu dem Dämmelement bzw. zu den Blechen des Gehäuses haben und auf diese Weise auch bei starker Einwirkung von Schallwellen auf das Dämmelement eine gute Dämpfungswirkung erreicht wird. Vorzugsweise umfasst ein solches Koppelelement ein Strangpressprofil mit einer Aufnahmenut und ein Dämpferelement mit einem Fuß, wobei der Fuß des Dämpferelementes in der Aufnahmenut gehalten ist. In weiterer Ausgestaltung umfasst das Strangpressprofil einen Halteabschnitt und eine im Abstand zu diesem angeordnete Anschlagleiste, die als Verdrehsicherung für Schrauben dient. Das Dämpferelement besteht vorzugsweise aus einem EPDM-Profil das einen inneren Dämpfungskörper und einen äußeren Dämpfungskörper und einen dazwischenliegenden Hohlraum umfasst. Eine solche Ausführung des Dämpferelements bietet unterschiedliche Dämpfungswirkungen, da die Dämpfungscharakteristik zunächst durch den äußeren Dämpfungs- körper bestimmt wird und erst bei Auftreffen des äußeren Dämpfungskörpers auf den inneren Dämpfungskörper eine andere Charakteristik der elastischen Eigenschaften bewirkt wird. Ein wesentlicher Vorteil der Koppelelemente ist deren Austauschbarkeit, nämlich durch die Verschraubung am Pfosten und das Einziehen des Dämpferelements in die Aufnahmenut. The vertical posts have opposite legs between which the ends of the insulating elements are received and supported against them by means of coupling elements. Such an arrangement has the advantage that the coupling elements in any load condition (full compression and full relief) always have contact with the insulating element or to the sheets of the housing and in this way, even with strong exposure to sound waves on the insulating a good damping effect is achieved. Preferably, such a coupling element comprises an extruded profile with a receiving groove and a damper element with a foot, wherein the foot of the damper element is held in the receiving groove. In a further embodiment, the extruded profile comprises a holding section and a stop bar arranged at a distance therefrom, which serves as an anti-twist device for screws. The damper element preferably consists of an EPDM profile which comprises an inner damping body and an outer damping body and an intermediate cavity. Such an embodiment of the damper element offers different damping effects, since the damping characteristic is initially determined by the outer damping mechanism. body is determined and only upon impact of the outer damping body on the inner damping body, a different characteristic of the elastic properties is effected. A major advantage of the coupling elements is their interchangeability, namely by the screw on the post and the insertion of the damper element in the receiving groove.

Die einzelnen Dämmelemente 3 sind als längliche Platten ausgebildet, die sich entlang einer Längsachse erstrecken, die horizontal zwischen den einzelnen Vertikalpfosten 2 verläuft. Zwischen zwei benachbarten Vertikalpfosten sind jeweils mehrere Dämmelemente 3 übereinander gestapelt. Für die Montage werden zunächst die Vertikalpfosten 2 aufgestellt und anschließend die Dämmelemente 3 von oben eingeführt und übereinander zwischen den Vertikalpfosten 2 gestapelt. Level of the insulating elements with arranged at the ends of the insulating elements stoppers. Fig. 1 shows a side view of an inventively designed sound insulating wall 1, which is formed by a number of vertical posts 2 with plate-shaped insulating elements 3 arranged therebetween. The vertical posts 2 have in the embodiment shown at its lower end depending on a screw 4, with which they are attached to a base, not shown. It may also be expedient to drive the vertical posts 2 into the ground, to embed them or to fix them in some other way. The individual insulating elements 3 are formed as elongated plates which extend along a longitudinal axis which extends horizontally between the individual vertical posts 2. Between two adjacent vertical posts a plurality of insulating elements 3 are stacked one above the other. For installation, first the vertical posts 2 are set up and then the insulation elements 3 are inserted from above and stacked one above the other between the vertical posts 2.
In Fig. 2 ist ein vertikaler Schnitt durch die Schalldämmwand 1 gezeigt. Der vom Schraubflansch 4 vertikal nach oben ragende Vertikalpfosten 2 besitzt seitliche Schenkel 5 zwischen denen die Enden der Dämmelemente 3 gehalten sind. Die Dämmelemente 3 besitzen einen Hohlquerschnitt, in dem jeweils ein die gesamte Höhe des Dämmelements 3 einnehmender Dämmstoffkörper 7 angeordnet ist. In Fig. 2 is a vertical section through the sound insulating wall 1 is shown. The vertically upwardly projecting from the screw flange 4 vertical post 2 has lateral legs 5 between which the ends of the insulating elements 3 are held. The insulating elements 3 have a hollow cross-section, in each of which a total height of the insulating element 3 engaging insulating body 7 is arranged.
In Fig. 3 ist ein vertikaler Schnitt durch ein Dämmelement 3 dargestellt, das ein Gehäuse 6 und einen darin befindlichen Dämmstoffkörper 7 umfasst. Das Gehäuse 6 besteht aus zwei abgekanteten Blechen 8 und 9, die sich im Decken und Bodenbereich des Gehäuses 6 formschlüssig überlappen. Der Bodenbereich des Gehäuses 6 ist als eine in Längsrichtung des Dämmelements 3 verlaufende Nut 10 gestaltet, wohingegen der Deckenbereich als Feder 11 geformt ist. Diese Formgebung ermöglicht es, dass die jeweils darüber bzw. darunter angeordneten Dämmelemente 3' und das Dämmelement 3 formschlüssig ineinandergreifen. Das der Schallquelle und somit beispielsweise den Gleisen zugewandte Blech 8 ist im vertikalen Abschnitt als Lochblech ausgeführt, so dass die Druck- bzw. Schallwellen in das Gehäuse 6 eintreten und vom Dämmstoffkörper 7 absorbiert werden können. Das Blech 9 auf der der Schallquelle abgewandten Seite ist im vertikalen Abschnitt ungelocht. Beide Bleche 8, 9 bestehen vorzugsweise aus Aluminium mit einer Blechdicke von ca. 1,5 mm. Selbstverständlich sind je nach Anforderungen und Einsatzbedingungen auch andere Blechdicken möglich, beispielsweise im Bereich von 1 ,0 mm bis 2,0 mm. In Fig. 3 is a vertical section through an insulating element 3 is shown, which comprises a housing 6 and an insulating body 7 therein. The housing 6 consists of two folded sheets 8 and 9, which overlap positively in the ceiling and bottom portion of the housing 6. The bottom region of the housing 6 is designed as a groove 10 extending in the longitudinal direction of the insulating element 3, whereas the ceiling region is shaped as a spring 11. This shaping makes it possible for the insulating elements 3 'and the insulating element 3 respectively disposed above and below to engage in one another in a form-fitting manner. The sound source and thus, for example, the tracks facing sheet 8 is designed in the vertical section as a perforated plate, so the pressure or sound waves can enter the housing 6 and be absorbed by the insulating body 7. The sheet 9 on the side facing away from the sound source is unperforated in the vertical section. Both sheets 8, 9 are preferably made of aluminum with a sheet thickness of about 1.5 mm. Of course, depending on the requirements and conditions of use, other sheet thicknesses are possible, for example in the range of 1, 0 mm to 2.0 mm.
Im Deckenbereich ist in dem Gehäuse 6 ein oberer Halter 12 angeordnet, der so gestaltet ist, dass ein trapezförmiger Abschnitt 13 der Form der Feder des Gehäuses 6 entspricht und zwischen seitlichen Profilen 14 ein Aufnahmeraum 15 für den oberen Abschnitt des Dämmstoffkörpers 7 gebildet ist, wobei der trapezförmige Abschnitt 13 eine Zwischenwand 13' aufweist. Der trapezförmige Abschnitt 13 und die seitlichen Profile 14 sind hohl ausgebildet, so dass im oberen Halter 12 am Ende stirnseitige Öffnungen 16 und 16' vorhanden sind. Im Bodenbereich ist in dem Gehäuse 6 ein unterer Halter 17 vorgesehen, der so gestaltet ist, dass zwischen seitlichen Profilen 18 eine der Nut 10 des Gehäuses 6 angepasste Form gegeben ist, wobei eine Mittenwand 18' zwischen den Profilen 18 angeordnet ist und darüber ein Aufnahmeraum 19 für den unteren Abschnitt des Dämmstoffkörpers 7 gebildet ist. Zwischen den seitlichen Profilen 18 ist die Mittenwand 18' mit einer zum Dämmstoffkörper 7 gerichteten Erhöhung 21 versehen, so dass seitliche Kanäle 20 gebildet werden, die eventuell am Dämmstoffkörper 7 sich niederschlagende Feuchtigkeit und demnach nach unten laufende Tropfen in Längsrichtung des Dämmelements 3 abführen. In the ceiling area, an upper holder 12 is arranged in the housing 6, which is designed so that a trapezoidal portion 13 corresponds to the shape of the spring of the housing 6 and between side profiles 14, a receiving space 15 is formed for the upper portion of the Dämmstoffkörpers 7, wherein the trapezoidal section 13 has an intermediate wall 13 '. The trapezoidal section 13 and the lateral profiles 14 are hollow, so that in the upper holder 12 at the end end openings 16 and 16 'are present. In the bottom area, a lower holder 17 is provided in the housing 6, which is designed so that between the side profiles 18 of the groove 10 of the housing 6 adapted shape is given, with a center wall 18 'is disposed between the profiles 18 and above a receiving space 19 is formed for the lower portion of the insulating body 7. Between the lateral profiles 18, the middle wall 18 'is provided with an elevation 21 directed towards the insulating body 7, so that lateral channels 20 are formed, which possibly dissipate moisture which precipitates on the insulating body 7 and thus drops running downwards in the longitudinal direction of the insulating element 3.
Die Fig. 4 zeigt eine Seitenansicht eines Stoppers 22, der im Ausführungsbeispiel einen T-förmig gestalteten Körper 23 mit einem Anschlagbereich 24 und von diesem abstehenden Schenkel 25 umfasst. An den äußeren Kanten des Anschlagbereichs 24 kann dieser abgeflacht sein. In Fig. 4 ist eine Ansicht des Stoppers 22 in Richtung des Pfeils V in Fig. 4 gezeigt. Das in Fig. 4 gezeigte Maß h entspricht der Höhe der Öffnung im trapezförmigen Abschnitt 13, und das in Fig. 5 gezeigte Maß b entspricht der unteren Breite der Trapezform dieser Öffnung, so dass der Schenkel 25 in diese Öffnung 16 einsteckbar ist und auf diese Weise der Stopper 22 befestigt wird. 4 shows a side view of a stopper 22, which in the exemplary embodiment comprises a T-shaped body 23 with a stop region 24 and leg 25 protruding therefrom. At the outer edges of the stop portion 24, this may be flattened. In Fig. 4 is a view of the stopper 22 in the direction of arrow V in Fig. 4 is shown. The dimension h shown in FIG. 4 corresponds to the height of the opening in the trapezoidal section 13, and the dimension b shown in FIG. 5 corresponds to the lower one Width of the trapezoidal shape of this opening, so that the leg 25 can be inserted into this opening 16 and in this way the stopper 22 is attached.
Die Fig. 6 zeigt einen Ausschnitt eines Horizontalschnitts durch eine Schalldämmwand 1 im Bereich eines die Enden der Dämmelemente 3 haltenden Vertikalpfostens 2. Der Vertikalpfosten 2 besteht aus einem Trägerprofil, das gegenüberliegende Schenkel 5 bzw. 5' und einen diese verbindenden Steg 26 umfasst. An den einander zugewandten Seiten der Schenkel 5 bzw. 5' sind Koppelelemente 27 angeordnet, die mittels Schrauben 28 und Muttern 29 an den Schenkel 5 bzw. 5' befestigt sind. Das Koppelelement 27 besteht vorzugsweise aus einem Aluminium-Strangpressprofil 31 und einem 6 shows a section of a horizontal section through a sound-absorbing wall 1 in the region of a vertical post 2 holding the ends of the insulating elements 3. The vertical post 2 consists of a carrier profile which comprises opposite legs 5 and 5 'and a web 26 connecting them. On the mutually facing sides of the legs 5 and 5 'coupling elements 27 are arranged, which are fastened by means of screws 28 and nuts 29 to the legs 5 and 5'. The coupling element 27 is preferably made of an aluminum extruded profile 31 and a
Dämpferelement 32 vorzugsweise aus EPDM. Das Strangpressprofil weist in einem Halteabschnitt 33 eine Aufnahmenut für einen Fuß 34 des Dämpferelements 32 auf. Die Koppelelemente 27 können unterschiedliche Höhen aufweisen, so dass Dämmelemente unterschiedlicher Dicke im Vertikalpfosten fixiert werden können. Bei einem eingesetzten Dämmelement 3 liegen äußere Dämpfungskörper 30 unter Vorspannung an den Blechen 8, 9 an, so dass ein ständiger Kontakt zum Dämmelement 3 gegeben ist. Bis zu einer bestimmten Größe werden auch Maßtoleranzen des Dämmelements 3 und/oder des Vertikalpfostens 2 ausgeglichen. Damper element 32, preferably made of EPDM. The extruded profile has in a holding portion 33 a receiving groove for a foot 34 of the damper element 32. The coupling elements 27 may have different heights, so that insulation elements of different thickness can be fixed in the vertical post. In an insulating element 3 used external damping body 30 are biased to the sheets 8, 9, so that a constant contact with the insulating element 3 is given. Up to a certain size and dimensional tolerances of Dämmelements 3 and / or the vertical post 2 are compensated.
Aus Fig. 6 geht hervor, dass die Enden bzw. Stirnseiten der Dämmelemente 3 offen sind. Der Abstand der Dämmelemente 3 zu dem Steg 26 des Vertikalpfostens 2 wird durch den endseitig angeordneten Stopper 22 aufrechterhalten, wie dies durch Fig. 7 deutlich wird. Die Fig. 7 zeigt einen Ausschnitt eines Vertikalschnitts durch die Schalldämmwand 1 im Bereich eines Vertikalpfostens 2. In der Ebene der Dämmelemente 3 befinden sich zu beiden Seiten des Stegs 26 die Enden der übereinander angeordneten Dämmelemente 3. In die Öffnungen 16 sind endseitig die Schenkel 25 des jeweiligen Körpers 23 eingesetzt, so dass die Stopper 22 auf diese Weise befestigt sind. Mittels der Anschlagbereiche 24 stützen sich die Dämmelemente 3 an dem Steg 26 des Vertikalpfostens 2 ab. Die erfindungsgemäße Gestaltung mit offenen Stirnseiten der Enden der Dämmelemente fuhrt zu einer Verringerung der Schallausbreitung, da gegenüber den bekannten Anordnungen metallische Teile entfallen sind, so dass die Schwingungen in diesem Bereich reduziert werden. Durch das offene Ende der Dämmelemente entwickelt sich dort kein definierter Schallschwingungsknoten, sondern es entsteht vielmehr eine unscharfe Schallreflexionsfläche, nämlich eine Überlagerung aus Schwingungsknoten und Schwingungsbäuchen. Wie sich überraschenderweise herausgestellt hat, verbessert sich dadurch die Schallabsorption im Randbereich des Dämmelements. From Fig. 6 shows that the ends or end faces of the insulating elements 3 are open. The distance of the insulating elements 3 to the web 26 of the vertical post 2 is maintained by the stopper 22 arranged at the end, as is clear from Fig. 7. In the plane of the insulating elements 3 are located on both sides of the web 26, the ends of the superimposed insulating elements 3. In the openings 16 are the ends of the legs 25th of the respective body 23, so that the stoppers 22 are fixed in this way. By means of the stop regions 24, the insulating elements 3 are supported on the web 26 of the vertical post 2. The design according to the invention with open end faces of the ends of the insulating elements leads to a reduction of the propagation of sound, as compared to the known arrangements metallic parts are omitted, so that the vibrations are reduced in this area. Due to the open end of the insulating elements, there is no defined sonic vibration node developing there, but instead a blurred sound reflection surface is formed, namely a superposition of vibration nodes and antinodes. As has surprisingly been found, this improves the sound absorption in the edge region of the Dämmelements.
