Das schallabsorbierende Bauelement 1 ist beidseitig mit der Vorsatzschale 3 aus Blähglas bedeckt. Die zur Lärmquelle gerichtete Oberfläche der ebenen Vorsatzschale 3 aus Blähglas kann eben oder strukturiert sein.The sound-absorbing component 1 is with the side strip 4 positively in a double U-profile. 5 a usually perpendicular to a base plate. 6 standing support 7 of a noise protection system used. The sound-absorbing component 1 is double-sided covered with the facing shell 3 made of expanded glass. The to Noise source directed surface of the flat facing shell 3 made of expanded glass can be flat or structured be.

    Alternativ zur Tragplatte 2 aus Beton kann die Tragplatte 2 aus Glasfaserbeton, mehrschichtigen Holzplatten oder Kunststoffplatten gebildet sein.As an alternative to the support plate 2 made of concrete, the support plate 2 made of fiberglass concrete, multilayer wood panels or plastic plates.

    Zur Herstellung einer Lärmschutzwand wird der Boden einer Schalung (8) mit einer Schicht aus einer Vielzahl von neben einander liegenden oder direkt aneinander liegenden plattenförmigen Blähglaselementen bedeckt und auf die Schicht Beton mit einer einstellbaren Mindestdickflüssigkeit aufgegossen. Je nach eingestellter Mindestdickflüssigkeit dringt der Beton beim Aufgießen bis zu 3 mm in die Oberfläche der die Vorsatzschale 3 bildenden, liegenden Blähglaselemente ein, so dass beim Aushärten eine feste Verbindung zwischen Tragplatte 2 und Vorsatzschale 3 entsteht und die so gebildete Lärmschutzwand aus der Schalung 8 gehoben und in die Stützen 7 des Lärmschutzsystems gehoben werden kann.To make a noise barrier, the floor a formwork (8) with a layer of a plurality from side by side or directly to each other covered lying plate-shaped Blähglaselementen and on the concrete layer with an adjustable Poured minimum thickness. Depending on the set Minimum thickness of the concrete penetrates the concrete Pour up to 3 mm in the surface of the attachment 3 forming, lying Blähglaselemente a, so that when curing a firm connection between Support plate 2 and 3 attachment shell arises and lifted the thus formed noise barrier from the formwork 8 and lifted into the supports 7 of the noise control system can be.

    Zur Herstellung einer Lärmschutzwand, die beidseitig mit der Vorsatzschale 3 aus Blähglas bedeckt ist, werden die vertikal angeordneten Schalungen (8) mit einer Schicht aus einer Vielzahl von neben einander liegenden oder direkt aneinander liegenden plattenförmigen Blähglaselementen bedeckt und der Beton mit einer einstellbaren Mindestdickflüssigkeit vertikal eingegossen. Je nach eingestellter Mindestdickflüssigkeit dringt der Beton beim Eingießen in die Oberfläche der die Vorsatzschale 3 bildenden Blähglaselemente ein, so dass beim Aushärten eine feste Verbindung zwischen Tragplatte 2 und Vorsatzschalen 3 entsteht und die so gebildete Lärmschutzwand aus der geöffneten Schalung (8) gehoben und in die Stützen 7 des Lärmschutzsystems gehoben werden kann.For making a noise barrier, the two-sided covered with the facing shell 3 made of expanded glass the vertically arranged formworks (8) with a Layer of a variety of juxtaposed or directly adjacent plate-shaped Blähglaselementen covered and the concrete with an adjustable Minimum thick liquid poured vertically. Depending on the set minimum thickness the concrete penetrates into the surface when pouring the facing shell 3 forming Blähglaselemente a, so that when curing a firm connection between Support plate 2 and 3 attachment shells arises and the like formed noise barrier from the open formwork (8) lifted and in the supports 7 of the noise protection system can be lifted.

    Alternativ zur Herstellung einer Lärmschutzwand mit auf- oder eingegossenem Beton auf die Vorsatzschale 3 können die Blähglaselemente auf die Tragplatte 2 einoder beidseitig aufgeklebt, gedübelt, mit Anker oder im Rahmen aufgebracht werden.Alternatively to the production of a noise barrier with poured or cast concrete on the front shell. 3 can the Blähglaselemente on the support plate 2 aoder glued on both sides, dowelled, with anchor or be applied in the frame.

    Lärmschutzwände oder schallabsorbierende Vorsatzschalen 3 können zur Befestigung an auf der Baustelle bereits vorhandene Wände auch geklebt, gedübelt und/oder mit Ankern und Rahmen befestigt werden. Im Tunnelbau ist die Tragplatte 2 aus Glasfaserbeton in Verbindung mit der Vorsatzschale 3 aus Blähglas als besonders dünnwandiges schallabsorbierendes Bauelement 1 mit Ankern durch die Seitenstreifen 4 auch bei beengten Raumverhältnissen in die Tunnelwandung montierbar. Noise barriers or sound-absorbing facing shells 3 can already be attached to at the construction site existing walls also glued, dowelled and / or anchored with anchors and frame. In tunnel construction is the support plate 2 made of fiberglass in conjunction with the front shell 3 made of expanded glass as special thin-walled sound-absorbing component 1 with anchors through the side strips 4 even in cramped Space conditions in the tunnel wall mountable.
