Definitions

  • the invention relates to a noise barrier according to the preamble of claim 1.
  • Noise barriers are erected on traffic routes in order to protect adjacent residential areas from the noise emanating from the traffic route.
  • noise barriers consist of steel, galvanized posts with interposed, interchangeable wall elements. Depending on the building material and wall system, certain frequencies are more or less attenuated. Elements that mainly reflect the sound have a small wall cross section and exist for example made of concrete, metal or plastic profiles. In contrast, elements that absorb sound for the most part are made wider and consist of a porous material, for example an open-pored expanded clay, facing concrete or rock wool. The sound penetrates the open-pored materials and is converted into heat.
  • a noise barrier known from DE-OS 38 12 394, which consists of a framework for holding and receiving wall parts, the wall parts consisting of planted cassettes which are stacked to form the wall height.
  • Such a noise barrier does not disturb the landscape, but offers an aesthetically successful sight. It offers a biotope for many small creatures and ensures that pollutants are removed and good heat absorption.
  • a noise protection wall constructed in accordance with DE-OS 38 12 394 sufficiently fulfills the 'Technical regulations and guidelines for the implementation of noise protection walls on roads' (ZTV-Lsw 88), which prescribe a reduction of the A-weighted sound insulation value by at least 25 dB .
  • a particular disadvantage is that in the case of noise barriers constructed according to DE-OS 38 12 394, vertical pipes for load distribution had to be installed subsequently in order to increase the stability of the noise barrier to the value required in ZTV-Lsw 88.
  • the invention has for its object to improve a noise protection wall of the type mentioned in such a way that its sound insulation and stability is increased with about the same installation and cost, without reducing the green, pollutant-reducing area.
  • the airborne sound insulation is approximately 31 to 36 dB, so that the technical regulation that 25 dB is required, more than is fulfilled.
  • a noise barrier of the type mentioned at the outset means that the noise is felt only about half as loud.
  • the low and medium frequencies, which are perceived as very disturbing are particularly insulated.
  • the fiber cement slab arranged in the middle in no way disturbs the visual impression and does not reduce the green area.
  • the installation of a fiber cement board is neither complex nor cost-intensive.
  • the intrinsic stability of the cassettes is significantly improved with the fiber cement board. It is therefore not necessary to install additional scaffolding elements.
  • the fiber cement board is at least 8 mm thick.
  • the mass achieved thereby shifts the natural resonance of the fiber cement board into a deep, uncritical frequency range, so that no excitation in the natural resonance can take place due to the disturbing sound frequencies.
  • the watering mat is arranged on both sides of the fiber cement board in the horizontal edge zones of a cassette.
  • the watering mat can be on horizontal edge of the cassette can be arranged in one piece or a one-piece watering mat can be arranged between two cassettes.
  • the cassette 20 shown in FIG. 2 differs from that shown in FIG. 1 in that it has an 8 mm thick fiber cement plate 26 as a nutrient medium on both sides no vegetation mat, but only a mineral fiber insulation board 24, which is greened directly.
  • the inherent stability of the cassette 10, 20 is significantly increased by the fiber cement plate 26, so that otherwise usual frame elements for stiffening the cassette can be omitted in practice.
  • FIG. 3 shows in an enlarged detail from FIG. 1 the lower end region of the cassette 10.
  • a one-piece watering mat 30 is arranged on the lower horizontal edge of the cassette 10. This has the effect that the water supplied via drip irrigation at the upper end of the noise barrier is retained in the cassettes and is dispensed to the plants in even doses on both sides of the fiber cement plate.
  • washing mat in two parts and to arrange it on both sides of the fiber insulation panel 16 in the edge region of the cassette.
  • FIG. 5 shows a graphical representation of the measured values of the noise insulation test of the cassette, which was carried out as part of the test procedure according to ZTV-Lsw 88.
  • the test procedure is called DIN 52 210-03-M-L-P-W.
  • the frequency f is shown on the abscissa, while the sound insulation index R is entered on the ordinate.
  • the sound insulation measured for the noise barrier according to the invention is between 34 and 39 dB. The particularly good insulation properties in the medium and low frequency range can be seen.
