Description

Lärmschutz-ElementNoise protection element

Die Erfindung betrifft ein neuartiges Lärmschutz - Element mit einem auf der dem Schall zugewandten Seite befindlichen Lochblech, einer dahinter, liegenden Stahlrahmenkonstruktion und einer auf der schallabgewandten Seite angebrachten witterungsbeständigen Holzbetonplatte. Dieses Lämischutz-Element ist nach gestalterischen und statischen Vorgaben in Bezug auf Ausfuhrungsdetails des Lochbleches, Gesamtfarbgebung, Farbgebung der Einzelteile des Elementes und deren Ausführung individuell und variabel gestaltbar und erreicht durch dieseThe invention relates to a new type of noise protection element with a perforated sheet on the side facing the sound, a steel frame construction behind it and a weather-resistant wood concrete plate on the side facing away from the sound. This noise protection element can be individually and variably designed according to design and static specifications in relation to the design details of the perforated sheet, overall coloring, coloring of the individual parts of the element and their design and achieves

&iacgr;&ogr; neuartige Kombination eine hohe Schallabsorption sowie insgesamt eine hohe Schalldämmung.This innovative combination provides high sound absorption and overall high sound insulation.

Stand der Technik: State of the art :

Schon seit längerem werden Lärmschutz - Elemente aus Aluminium oder Edelstahl in verschiedenen Längen zwischen 2000 mm und 4000 mm, Höhen von 330 mm bis 500 mm und einer Tiefe von 120 mm hergestellt. Die Vorderseiten der bisher gebräuchlichen Elemente sind aus Lochblechen hergestellt. Diese Lochbleche haben einen Lochanteil, welcher der Absorptionsfläche entspricht, von ca. 30 %. Die Materialstärken dieser Lochbleche liegen bei Aluminium bei 0,8 mm und bei Edelstahl bei 1,2 mm. Die in Blech ausgeführte Rückseite dieser Elemente wird dann ohne Lochanteil ausgeführt. Als Schallabsorber wird zwischen den Blechen meist ein maximal 40 mm starker Faserdämmstoff eingesetzt. Dadurch liegt das Gewicht solcher Elemente bei 22 kg/qm. Bedingt durch den niedrigen Öffhungsanteil in der Frontfläche (dem Schall zugewandt) werden nur Schallabsorptionswerte von maximal 8 dB erreicht, die somit an der unteren Grenze des in der ZTV Lsw 88 als „hochabsorbierend" (>= 8 dB) festgelegten Wertebereiches liegen.Noise protection elements made of aluminum or stainless steel have been manufactured for some time now in various lengths between 2000 mm and 4000 mm, heights from 330 mm to 500 mm and a depth of 120 mm. The front sides of the elements used to date are made of perforated sheets. These perforated sheets have a hole proportion, which corresponds to the absorption surface, of around 30%. The material thickness of these perforated sheets is 0.8 mm for aluminum and 1.2 mm for stainless steel. The back of these elements, made of sheet metal, is then made without any holes. A fiber insulation material with a maximum thickness of 40 mm is usually used between the sheets as a sound absorber. This means that the weight of such elements is 22 kg/m². Due to the low proportion of openings in the front surface (facing the sound), only sound absorption values of a maximum of 8 dB are achieved, which are therefore at the lower limit of the value range defined in ZTV Lsw 88 as "highly absorbent" (>= 8 dB).

Beschreibung:Description:

Aufgabe der Erfindung ist es, ein Lärmschutz - Element zu entwickeln, welches sehr gute Schallabsorptionswerte mit der einfachen Konstruktion einer Metallfront verbindet. Hierbei wird anstelle einer Faserdämmstoffplatte eine Holzbetonplatte hinter der Metallfront eingesetzt. Die tragende Funktion dieses Lärmschutzelementes übernimmt eine Stahlrahmenkonstruktion, die sich zwischen dem Lochblech und der Holzbetonplatte befindet. Dadurch bildet sich automatisch eine Luftschicht zwischen der Front und der Holzbetonplatte, die die Schallabsorption bzw. Schalldämmung zusätzlich verbessert.The aim of the invention is to develop a noise protection element that combines very good sound absorption values with the simple construction of a metal front. Instead of a fiber insulation board, a wood concrete board is used behind the metal front. The supporting function of this noise protection element is taken over by a steel frame construction that is located between the perforated sheet and the wood concrete board. This automatically creates an air layer between the front and the wood concrete board, which further improves sound absorption and sound insulation.

Die Erfindung wird nachstehend am Ausfuhrungsbeispiel mit Figur 1 erläutert.
Nach Figur 1 besteht das Lärmschutz-Element aus einem, dem Lärm zugewandten Lochblech 1 und einer Holzbetonplatte 4 auf der dem Schall abgewandten Seite. Befestigt werden das Lochblech 1 und die Holzbetonplatte 4 an einer dazwischen liegenden Stahlrahmenkonstruktion 2. Diese Stahlrahmenkonstruktion 2 umschließt das gesamte Lärmschutz-Element und hält das Lochblech 1 und die Holzbetonplatte 4 auf Abstand. Somit ergibt sich dort eine Luftschicht 3, die eine Verbesserung der Schallabsorption bewirkt.The invention is explained below using the exemplary embodiment shown in Figure 1.
According to Figure 1, the noise protection element consists of a perforated sheet 1 facing the noise and a wood concrete slab 4 on the side facing away from the sound. The perforated sheet 1 and the wood concrete slab 4 are attached to a steel frame construction 2 in between. This steel frame construction 2 encloses the entire noise protection element and keeps the perforated sheet 1 and the wood concrete slab 4 at a distance. This creates an air layer 3 there, which improves sound absorption.
