Mit dem im folgenden beschriebenen Drahtkorb können Lärmschutzwände errichtet werden, mit denen sehr hohe Schalldämmwerte erzielbar sind. So können mit aus solchen Drahtkörben erstellte Lärmschutzwände einen Schalldämmwert von mehr als 25 dB(A) ohne weiteres aufweisen.Noise barriers can be installed with the wire basket described below to achieve very high sound insulation values. Thus, noise barriers made from such wire baskets can easily have a sound insulation value of more than 25 dB (A).
Der Drahtkorb wird aus einzelnen Drahtgittern zusammengesetzt. Wie aus
Mit Abstand zu den Seitenwänden 4 befindet sich innerhalb des Drahtkorbes jeweils ein Trenngitter 7, das ebenfalls als Drahtgitter mit senkrecht einander kreuzenden Gitterstäben ausgebildet ist. In
Die äußeren Kammern 12, 13 nehmen Füllgut auf, das beispielsweise aus Steinen besteht. Sie können unterschiedlichster Art und Größe sein, insbesondere im Hinblick auf ein gewünschtes Aussehen der zu errichtenden Lärmschutzwand ausgewählt werden. Anstelle der Steine kann in die Kammern 12, 13 beispielsweise auch Erde oder eine Mischung aus Steinen und Erde eingebracht werden. Dadurch kann die aus den Drahtkörben zu errichtende Lärmschutzwand optisch an die vorhandene Umgebung optimal angepaßt werden.The
Der Aufnahmeraum 11 enthält das zur Schalldämmung vorgesehene Material, das in Richtung auf die Seitenwände 4 durch die in den Kammern 12, 13 befindliche Schüttung verdeckt ist. Für die Schalldämmung wird Sand 14 verwendet, der sich in einem Sack 15 befindet. Er ist vorteilhaft aus Vlies hergestellt. Er ist so groß, daß er, wenn er mit Sand gefüllt ist, den Aufnahmeraum 11 vollständig ausfüllt. Die Trenngitter 7 stabilisieren den Sack 15 an seinen einander gegenüberliegenden Längsseiten. An den anderen Seiten wird der Sack 15 durch einen Teil der Drahtgitter 1 bis 3 und 6 abgestützt.The receiving
Der Sack 15 ist vollständig geschlossen. Die Distanzhalter 8 beschädigen den Sack 15 nicht, da die Enden der Distanzhalter zur Bildung der Haken 9, 10 abgerundet sind.The
Die Trenngitter 7 ragen mit den freien Enden ihrer Längs- und Querdrähte in die Drahtgitter 1 bis 3 und 6. Eine gesonderte Befestigung der Trenngitter 7 mit diesen Drahtgittern 1 bis 3 und 6 ist nicht erforderlich.The
Wie sich aus
Die
Bei der Herstellung der Lärmschutzwand werden zunächst die beiden äußeren Kammern 12, 13 mit Steinen, Erde und dergleichen gefüllt. Die Kammern 12, 13 bleiben durch die Distanzhalter 8 formstabil. Dann wird in den Aufnahmeraum 11 der Sack 15 eingelegt, der nunmehr mit Sand gefüllt wird. An den Stirnseiten des Sackes 15 entstehen in der beschriebenen Weise zwischen den Gitterstäben 19, 20 der Trennwand 2 oder 3 die Ausbauchungen 23, die sich bis in den jeweils benachbarten Korb 16, 17 ausdehnen. Der Sack 15 des jeweils benachbarten Drahtkorbes legt sich mit seinen Ausbauchungen an die Ausbauchungen des Sackes 15 des anderen Drahtkorbes an, wodurch die durch die Querdrähte verursachten Lücken geschlossen werden. Auf diese Weise werden einwandfrei geschlossene Fugen zwischen den aneinanderstoßenden Säcken 15 gebildet, so daß sich keine Schalldämmverluste ergeben.In the manufacture of the noise barrier, first the two
Mit der beschriebenen Ausbildung kann ein statisch stabiles Bauwerk erstellt werden. Bauhöhen, wie sie für Lärmschutzwände üblich sind, können damit problemlos realisiert werden. Dabei läßt sich der Drahtkorb einfach und preiswert fertigen und errichten. Es werden für ihn nur die Drahtgitter 1 bis 4, 6 sowie der Sack 15 verwendet. Sand als Absorbermaterial zum Einfüllen in den Sack 15 steht überall zur Verfügung. Der Sack 15 kann beispielhaft eine Breite von nur 20 cm aufweisen, um Schalldämmwerte von 25 dB(A) zu gewährleisten.With the described training, a statically stable structure can be created. Building heights, as they are customary for noise barriers, can thus be easily realized. Here, the wire basket can be easily and inexpensively manufacture and build. It will be used only the
Die
Vorteilhaft ist es jedoch, im Bereich der gefüllten Säcke 15 der Drahtkörbe 21, 22 eine Zwischenlage 24 vorzusehen, die die Lücke zwischen den aneinanderstoßenden Säcken 15 in der Einbaulage schließt. Die Zwischenlage 24 besteht vorteilhaft aus einem schlauchförmigen Sack 25, der mit Sand 26 gefüllt ist. Seine Höhe und vorzugsweise auch seine Breite entspricht der Höhe und Breite der Säcke 15 in den Drahtkörben 21, 22. Werden die benachbarten Drahtkörbe 21, 22 dicht aneinandergesetzt, dann wird der Sand 26 im Sack 25 so verdrängt, daß die Zwischenräume zwischen den Ausbauchungen 23 der Drahtkörbe 21, 22 ausgefüllt werden (
Der Drahtkorb gemäß den
Gemäß
Zwischen den voneinander abgewandten Seitenwänden 4 der Kammern 12 und 13 sind weitere Distanzhalter 8' vorgesehen, die sich über die ganze Breite des Drahtkorbes erstrecken und mit ihren Hakenenden 9' und 10' jeweils in eine der Seitenwände 4 eingehängt sind. Die so angeordneten Distanzhalter 8' durchqueren den Aufnahmeraum 11 quer, vorzugsweise senkrecht zu dessen Längserstreckung. Die Distanzhalter 8' sind bis auf ihre größere Länge gleich ausgebildet wie die Distanzhalter 8. Bei der Ausführungsform gemäß
Auf jedem Distanzhalter 8' sind jeweils zwei im Bereich der Kammern 12 und 13 liegende Distanzrohre 28 vorgesehen. Jedes Distanzrohr 28 hat eine Länge, die der Breite der Kammern 12 und 13 entspricht. Die Distanzrohre 28 gewährleisten, daß der Aufnahmeraum 11 mit dem darin befindlichen Sack 15 (in
Wie insbesondere die
In ihrem überstehenden Endabschnitt weist das Rohrende 29 miteinander fluchtende Durchstecköffnungen 31, 31' auf, die in einem Winkelabstand von 90° zu den Aussparungen 33, 33' liegen. Zur Befestigung der Distanzrohre 28 an den Trennwänden 7 wird durch die Durchstecköffnungen 31, 31' ein Stift 32 gesteckt, dessen freies Ende über die Durchstecköffnungen 31' ragt (
Um die Distanzhalter 8' mit den Distanzrohren 28 in den Drahtkörben zu montieren, wird zunächst auf den in Einschubrichtung rückwärtigen Teil des Distanzhalters 8' eines der Distanzrohre 28 geschoben. Es wird so auf den Distanzhalter 8' aufgesetzt, daß sein die Aussparungen 33, 33' aufweisendes Ende 29 in Steckrichtung nach vorn weist. Danach wird der Distanzhalter 8' mit seinem vorderen Hakenende 10' durch eine Maschenöffnung in der Seitenwand 4, zum Beispiel der Kammer 12, und weiter durch eine mit dieser fluchtenden Maschenöffnung der Trennwand 7 geschoben. Danach wird der Distanzhalter 8' mit seinem vorderen Hakenende 10' durch (nicht dargestellte) Öffnungen im Sack 15, danach durch eine Maschenöffnung im benachbarten Trenngitter 7 der Kammer 13 und schließlich durch eine mit dieser fluchtenden Maschenöffnung in deren Seitenwand 4 geschoben. Danach wird der Distanzhalter 8' so im Korb ausgerichtet, daß sein rückwärtiges Hakenende 9' in einen benachbarten Querdraht der Seitenwand 4 der Kammer 12 eingehängt werden kann. Dabei befindet sich das Distanzrohr 28 in der Kammer 12 zwischen den einander benachbarten Seiten- und Trennwänden 4 und 7. In dieser Lage liegt das Distanzrohr 28 mit seinem anderen Rohrende 35 am Gitter 4 innenseitig an, während sein Ende 29 so ausgerichtet werden muß, daß ein Gitterstab der Trennwand 7 in die Aussparungen 33, 33' zu liegen kommt. Danach kann das Distanzrohr 28 am Trenngitter 7 arretiert werden, wozu der Stift 32 von oben durch die Öffnungen 31, 31' des Rohrendes 29 gesteckt wird. Anschließend wird von der Seitenwand 4 der Kammer 13 aus durch die Maschenöffnung, durch die der Distanzhalter 8' mit seinem Hakenende 10' ragt, das andere Distanzrohr 28 über das Hakenende 10' geschoben und so ausgerichtet, daß einer der Gitterstäbe der Trennwand 7 der Kammer 13 in die Aussparungen 33, 33' zu liegen kommt. Das andere Ende 35 des Distanzrohrs 28 liegt von innen an der Seitenwand 4 der Kammer 13 an. Danach kann auch dieses Distanzrohr 28 mit dem Stift 32 gesichert werden. Nun muß nur noch das andere Hakenende 10' des Distanzhalters 8' in den benachbarten Querdraht der Seitenwand 4 eingehängt werden, um eine einwandfreie Befestigung des Distanzhalters 8' im Drahtkorb zu gewährleisten. Entsprechend werden auch alle anderen Distanzhalter 8' mit ihren Distanzrohren 28 an den Drahtkorbwänden 4, 7 montiert.To mount the spacers 8 'with the
Die montierten Stifte 32 liegen innerhalb des Aufnahmeraumes 11. Wie sich aus
Die beschriebene Anordnung und Ausbildung der Distanzhalter 8, 8' der Distanzrohre 28 gewährleisten eine hohe Formsteifigkeit der Kammern 12 und 13 und des Aufnahmeraumes 11, so daß diese beim Befüllen und während des Gebrauchs des Drahtkorbes nicht übermäßig verformt werden.The described arrangement and design of the
Mit den Distanzrohren 28 ist es sicher möglich, die Trennwände 7 des Aufnahmeraumes 11 gegeneinander abzustützen, so daß der Aufnahmeraum 11 bereits befüllt werden kann, bevor die Kammern 12 und 13 mit Steinen oder dergleichen befüllt werden. Die Distanzrohre 28 verhindern, daß die Trennwände 7 beim Füllen des Sackes 15 mit Sand nach außen ausbauchen. Gleichzeitig stellen die mit ihren Hakenenden 9', 10' in die Seitenwände 4 eingehängten Distanzhalter 8' sicher, daß die Seitenwände 4 durch die Füllung der Kammern 12, 13 nicht oder nur wenig nach außen ausbauchen.With the
Bei der Montage lassen sich die Hakenenden 9' bzw. 10' der Distanzhalter 8' problemlos durch den Sack 15 schieben. Er kann hierfür kleine Durchstecköffnungen aufweisen. Bei entsprechendem Sackmaterial ist es möglich, daß das Hakenende 9' bzw. 10' beim Montagevorgang die Sackwandung durchbricht.During assembly, the hook ends 9 'and 10' of the spacer 8 'can easily push through the
Die Distanzhalter 8' mit den Distanzrohren 28 werden ebenso wie die Distanzhalter 8 so verteilt im Drahtkorb angeordnet, daß die Seitenwände 4 und die Trennwände 7 optimal gegen Verformung durch die im Aufnahmeraum 11 und in den Kammern 12, 13 befindlichen Materialien abgestützt sind. In den Kammern 12, 13 können zusätzlich auch die Distanzhalter 8 gemäß den
Der transportable Drahtkorb gemäß
Die Einbuchtungen 36, 37 werden dadurch gebildet, daß die horizontalen Querdrähte der Drahtgitter 2, 3 in diesem Bereich entsprechend gebogen sind. Die Querdrähte können über die Höhe des Drahtkorbes in ungleichen Abständen angeordnet sein, wie
Die Lärmschutzwand gemäß
In der Lärmschutzwand liegen die Drahtkörbe mit den seitlichen Gitterabschnitten 2', 2" und 3', 3''' der Drahtgitter 2 bzw. 3 aneinander an, wobei zwischen ihnen die Aufnahmekanäle 42 bis 44 gebildet sind. Die darin angeordneten Sandsäcke ragen ebenso wie die Sandsäcke 15 in den Aufnahmeräumen 11 durch die Gitteröffnungen in den Bodenabschnitten 38, 39. Die Gitteröffnungen haben entsprechend große Querschnitte. Dadurch liegen die gefüllten Sandsäcke 15 in den Aufnahmeräumen 11 und in den Aufnahmekanälen 42 bis 44 über die Höhe der Gitterkörbe lückenlos aneinander an. Die Trennfugen zwischen den gefüllten Sandsäcken werden vollständig verschlossen. Auf diese Weise wird eine einwandfreie Abdichtung der Fugen der Drahtkörbe erreicht. Während bei der Ausführungsform nach
Die
Es können mehrere solcher Drahtkorbpaare zur Bildung einer längeren Lärmschutzwand nebeneinander gesetzt werden. Dann werden entsprechend der Ausführungsform gemäß
Je nach Höhe der zu errichtenden Lärmschutzwand können auch mehr als zwei Drahtkörbe aufeinander gesetzt werden. Die aufeinander gesetzten Drahtkörbe können auch gleich groß sein. Dann hat die Lärmschutzwand über ihre Höhe konstante Dicke.Depending on the height of the noise barrier to be built and more than two wire baskets can be placed on each other. The stacked wire baskets can also be the same size. Then the noise barrier has constant thickness over its height.
Es ist ferner möglich, nebeneinander unterschiedlich breite Drahtkörbe zu setzen. Die Einbuchtungen sind dabei so an den Drahtkörben vorgesehen, daß sie bei aneinander gesetzten Drahtkörben die Aufnahmekanäle bilden.It is also possible to set side by side different width wire baskets. The indentations are provided on the wire baskets that they form the receiving channels in each other set wire baskets.
Bei den dargestellten Ausführungsformen sind die Einbuchtungen 36, 37 außermittig in den stirnseitigen Drahtgittern 2, 3 vorgesehen, so daß die Kammern 12, 13 unterschiedlich groß sind. Die Einbuchtungen 36, 37 können selbstverständlich auch mittig in den Drahtgittern 2, 3 angeordnet sein. In diesem Fall sind die Kammern 12, 13 gleich groß.In the illustrated embodiments, the
