In Fig. 1 wird mit 1 das Pfostenelement bezeichnet, das in der bevorzugten erfindungsgemäßen Ausführungsform einen I-förmigen Querschnitt aufweist. Die Pfostenelemente können auch aus Vierkantrohren gebildet sein. An diesem Pfosten 1 ist die linke Seite des erfindungsgemäßen Rahmens des Lärmschutzwandsegments anliegend angeordnet, z.B. eingeschoben oder angelascht. In gleicher Weise ist der nicht abgebildete rechte Pfosten an der rechten Kante des Rahmens ausgebildet.In Fig. 1, 1 denotes the post element which, in the preferred embodiment according to the invention, has an I-shaped cross section. The post elements can also be formed from square tubes. At this post 1 is the left side of the frame of the noise barrier wall segment according to the invention arranged adjacent, eg inserted or lashed. In the same way, the right post, not shown, is formed on the right edge of the frame.
Der Rahmen besteht aus zwei vertikalen Rahmenholmen 2, dem unteren horizontalen Rahmenholm 5 und den beiden oberen Versteifungsholmen 3 und 4, die derart an den oberen Endbereichen der vertikalen Rahmenholme 2 angeschlagen sind, daß sie diese miteinander verbinden und den Schlitz bilden, durch den wenigstens eine Schallschluckplatte 8 geführt ist. Der vordere Versteifungsholm 3 ist mit den seitlichen vertikalen Rahmenholmen 2 starr verbunden bzw. einstückig ausgebildet. Andererseits ist der hintere Versteifungsholm 4 demontabel ausgebildet, d.h., daß er beispielsweise mit einer lösbaren Schraube 4b oder einem anderen an sich bekannten Befestigungselement in seiner Position lösbar fixiert ist.The frame consists of two
Auf den nach innen weisenden Flächen der vertikalen Rahmenholme 2 sind in einer Halterung 6 Federgummis 7 angeordnet, an denen jeweils eine senkrechte Kante der Schallschluckplatte 8 in montiertem Zustand anliegt.On the inward-facing surfaces of the vertical frame spars 2 6 spring rubbers 7 are arranged in a holder, against each of which a vertical edge of the
In gleicher Weise ist auf der nach innen weisenden Fläche des unteren horizontalen Rahmenholmes 5 Halterung 6 mit Federgummi 7 angeordnet, an dem die Unterkante der Schallschluckplatte 8 anliegt.In the same way, holder 6 with spring rubber 7 is arranged on the inward-facing surface of the lower horizontal frame spar 5, against which the lower edge of the
In den Versteifungsholmen 3 und 4 ist, bevorzugt mittig bezüglich der innen liegenden Schallschluckplatte 8, eine die Schallschluckplatte 8 an dieser Stelle durchtretene Bohrung 9 ausgebildet; in montiertem Zustand befindet sich in der koaxialen Öffnung (koaxial bezogen auf die Achse der Bohrung 9) in der Schallschluckplatte 8 ein ringförmiges Bauelement 9a, das zum einen die Distanz zwischen den Holmen 3 und 4 hält und zum anderen die Schallschluckplatte 8 in montiertem Zustand sichert, wenn ein Gewindebolzen in die Bohrung 9 eingebracht und die Anordnung durch den Gewindebolzen und eine Kontermutter gesichert und verriegelt ist. Durch eine Befestigung der Schallschluckplatte 8 nahezu in der Mitte ist ein ungehindertes Arbeiten des Glases gewährleistet.In the stiffening bars 3 and 4, preferably centrally in relation to the inner
Eine bevorzugte Ausführungsform des erfindungsgemäßen Rahmens wird ausschnittsweise in Fig. 2 wiedergegeben. Bei dieser Aufsicht auf den Eckenbereich des Rahmens besitzen die Bezugszeichen die zuvor gegebene Bedeutung, wobei jedoch in den nach innen weisenden Flächen der vertikalen Rahmenholme 2 jeweils mindestens eine senkrecht verlaufende Nut ausgebildet ist, in der Halterung 6 und Federgummi 7, vorzugsweise mit U-förmigem Querschnitt, angeordnet sind. In dieser Nut wird die anliegende Kante der Schallschluckplatte 8 anliegend gesichert.A preferred embodiment of the frame according to the invention is shown in detail in FIG. 2. In this view of the corner area of the frame, the reference numerals have the meaning given above, but in each case at least one perpendicular groove is formed in the inwardly facing surfaces of the vertical frame spars 2, in the holder 6 and spring rubber 7, preferably with a U-shaped one Cross section, are arranged. The adjacent edge of the
Bevorzugt ist in gleicher Weise auf der nach innen weisenden Fläche des unteren horizontalen Rahmenholms 5 eine entsprechende Nut mit innen liegender Halterung 6 und Federgummi 7 ausgebildet, in der die Unterkante der schluckplatte 8 anliegend gesichert ist.In the same way, a corresponding groove is preferably formed in the same way on the inward-facing surface of the lower horizontal frame spar 5 with an inner holder 6 and spring rubber 7, in which the lower edge of the
In Fig. 3 wird schematisch dargestellt, wie die Randbereiche des erfindungsgemäßen Rahmens in den Pfosten 1 lösbar gesichert sind. Hierbei liegt die Rahmenvorderkante im Bereich der vertikalen Rahmenholme 2 an einem freien Schenkel des Trägers 1 mit U- bzw. I-förmigem Querschnitt flächig an, während zwischen dem anderen freien Schenkel des Trägers 1 und der anderen Seite der vertikalen Rahmenholme 2 ein Klemm- bzw. Distanzelement 10 angeordnet ist, das sich beispielsweise auf der Innenseite des einen freien Schenkels des Trägers 1 abstützt und dessen anderes Ende gegen die gegenüberliegende Seite des vertikalen Rahmenholms 2 verriegelnd preßt. Dadurch, daß dieser Klemmbolzen oder dieser Distanzhalter lösbar ausgebildet ist, ist eine überaus leichte und bequeme Montage und Demontage des Rahmens des erfindungsgemäßen Lärmschutzwandsegments möglich.In Fig. 3 it is shown schematically how the edge regions of the frame according to the invention are releasably secured in the post 1. Here, the front edge of the frame lies flat in the area of the vertical frame spars 2 on a free leg of the carrier 1 with a U-shaped or I-shaped cross-section, while a clamping or. Between the other free leg of the carrier 1 and the other side of the vertical frame spars 2
Vorzugsweise ist die in den Rahmen eingeschobene Schallschluckplatte 8 um bis zu 50 % höher als der Rahmen bzw. als die vertikalen Rahmenholme 2, so daß, umgekehrt ausgedrückt, bei vorgegebener Segmenthöhe der Rahmen eine Höhe haben muß, die nur etwa zwei Drittel der Höhe der Schallschluckplatte 8 beträgt.Preferably, the is inserted into the frame
Aus Gründen der Festigkeit und Stabilität besteht die Schallschluckplatte 8 dazu aus einem Kunstglasmaterial, insbesondere einem Acrylglasmaterial.For reasons of strength and stability, the
Bei einem bevorzugten Ausführungsbeispiel der Erfindung ist die Schallschluckplatte aus Acrylglaselementen zusammengesetzt, die an ihren vertikalen Rändern spundwandartig ineinandergreifende Sicken und Stege aufweisen.In a preferred exemplary embodiment of the invention, the sound-absorbing plate is composed of acrylic glass elements which have beads and webs that interlock with one another at their vertical edges.
Bei einem weiteren bevorzugten Ausführungsbeispiel der Erfindung besteht die Schallschluckplatte 8 aus einem Kunstglas, insbesondere einem Acrylglas mit eingegossenen Polyamidfäden, das beispielsweise unter der Bezeichnung "Paraglas" von der Firma Degussa auf dem Markt erhältlich ist.In a further preferred exemplary embodiment of the invention, the
Die Materialien eines derartigen Kunstglases sind so gewählt, daß die eingebetteten Polyamidfäden keine Molekülbindung mit dem Kunstglas, insbesondere dem Acrylglas eingehen. Das hat den Vorteil, daß bei einem Aufprall eines Fahrzeuges die Schallschluckplatte zwar reißen kann, aber aufgrund der eingebetteten Polyamidfäden, die in Folge der fehlenden Molekülbindung im Acrylglas gleiten können, der Zusammenhalt erhalten bleibt. Fangnetze zum Schutz bei Aufprallunfällen, die bisher notwendig sind, erübrigen sich dadurch.The materials of such an artificial glass are chosen so that the embedded polyamide threads do not form a molecular bond with the synthetic glass, in particular the acrylic glass. This has the advantage that the sound absorbing plate can tear in the event of a vehicle crash, but the cohesion is retained due to the embedded polyamide threads, which can slide in the acrylic glass due to the lack of molecular bonding. This eliminates the need for safety nets to protect against impact accidents that were previously necessary.
Wenn weiterhin die eingebetteten Polyamidfäden schwarz gefärbt und vertikal angeordnet sind, ist gleichzeitig der vorgeschriebene Vogelschutz gewährleistet.If the embedded polyamide threads are also dyed black and arranged vertically, the prescribed bird protection is guaranteed at the same time.
Bei einem Lärmschutzwandsegment mit diesem Aufbau ist es möglich, statt der bisher notwendigen Pfostenfolge von etwa 2 m eine Pfostenfolge von nur etwa 5 bis 6 m mit mehreren, insbesondere drei Schallschutzplatten vorzusehen und die Schallschluckplatten bis zu einem Meter über den Rahmen vorstehen zu lassen. Die nebeneinander liegenden Schallschutzplatten sind an den Stoßstellen durch Kunststoffprofile aus Polykarbonat miteinander verbunden. Das hat zur Folge, daß die aufgrund der kurzen Pfostenfolge bei den bekannten Lärmschutzwänden stark beeinträchtigte Sicht erheblich verbessert ist.In the case of a noise protection wall segment with this structure, it is possible, instead of the previously required post sequence of about 2 m, to provide a post sequence of only about 5 to 6 m with several, in particular three, soundproof panels let the sound absorbing plates protrude up to one meter above the frame. The adjacent soundproofing panels are connected to each other at the joints by plastic profiles made of polycarbonate. As a result, the view, which is severely impaired due to the short post sequence in the known noise barriers, is considerably improved.
Der erfindungsgemäße Rahmen mit oder ohne innen liegender Schallschluckplatte 8 kann fabrikmäßig vorgefertigt werden; nach Setzen der Pfosten 1 in entsprechendem Abstand und entsprechender Ausrichtung kann durch Einschub der Rahmen zwischen die Pfosten die erfindungsgemäße Lärmschutzwand in kürzester Zeit montiert werden. Soll eine Schallschluckplatte 8 nachträglich eingebaut oder ausgebaut werden, ohne den Rahmen auszutauschen, wird in einfacher Weise der demontable Versteifungsholm 4 demontiert, die Schallschluckplatte 8 entnommen oder eingeführt und der Holm 4 wieder montiert.The frame according to the invention with or without an internal
