Definitions

  • the invention relates to an ecological noise barrier in lightweight construction with sound-absorbing insulation materials from natural and renewable raw materials, in particular a noise barrier against traffic noise, which is arranged with vertical, anchored in a foundation columns on roads or other sources of noise.
  • Noise protection thus becomes a fundamental need for environmental protection. Also for reasons of environmental protection are in the selection of materials for noise protection such aspects as environmental impact, ecology, economy but also waste disposal and acceptance of local residents to consider. From these points of view, noise protection measures based on renewable raw materials such as wood and straw have proved their worth.
  • the Noise protection modules consist of a piling device with crossbeams, to which a roof device is attached. Each noise protection module has a height of about 3 m, a length of about 5 m and a width of 75 cm to 110 cm. The spaces between the piles are filled with conventional straw bales in the known dimensions. In this way, a noise protection wall of any length can be built by juxtaposing the noise protection modules.
  • noise barrier in lightweight construction, for example, in the DE 42 12 172 A1 described.
  • the noise barrier consisting of stacked rockwool does not meet all ecological requirements.
  • the noise protection wall presents comparatively even and uniform attack surfaces, which are sprayed with graffiti to an increasing extent on traffic routes. From the overall aesthetic perspective, graffiti-contaminated noise barriers are extremely unsatisfactory for travelers.
  • Sound barrier walls at railway embankments are exposed to significant dynamic loads due to pressure fluctuations, which require a solid construction due to passing high-speed trains. Due to pressure waves and suction waves at the beginning and end of high-speed trains, the holders of the soundproofing elements can be loosened over time such that the soundproofing elements themselves tend to oscillate. For this reason, aluminum noise control elements must have a relatively large mass in order to avoid natural vibrations. Otherwise, the impact of the pressure waves and suction waves creates structure-borne noise in the noise protection wall, which is emitted by vibrations on the surface as airborne sound. The input impedance of the noise barrier must then be increased by increasing the mass. Otherwise, the noise barrier must be dampened with sound deadening or with heavy mats. For the reasons mentioned aluminum noise barriers are less well suited for lightweight construction.
  • the invention aims an ecological noise barrier in lightweight construction with sound-absorbing insulation materials from natural and renewable raw materials, which can be constructed with technically simple means and with good sound insulation properties also has a high stability against dynamic loads on roads and railways with high-speed trains.
  • the dimensions of the chopped straw particles or straws should be in a range between 10 mm to 50 mm, preferably between 20 mm and 30 mm.
  • flexible wedge-shaped sound absorption elements made of straw are so insensitive to pressure waves that they are suitable for use on high-speed roads. Pressure waves and suction waves do not cause natural oscillations in sound-absorbing elements made of straw. The weight and mass of the sound-absorbing elements can therefore be kept low. In this way, the wedge-shaped sound-absorbing elements can be stored by simple means by hand, transported and mounted without additional lifting equipment.
  • Wedge-shaped sound absorption elements are stackable due to their dimensions with a small footprint.
  • the wedge-shaped sound-absorbing elements can be manufactured inexpensively and offered in large quantities in retail, for example in hardware stores and sold.
  • the sale in the retail sector offers the possibility of individual and cost-effective construction of noise barriers by individual persons if the available funds of the municipalities are insufficient for noise abatement measures.
  • wedge-shaped noise protection elements with sound-absorbing insulation made of straw the currently still unsolved problem of noise control on busy traffic routes can be met with simple means.
  • wedge-shaped sound-absorbing elements do not provide a graffiti attack surface.
  • the ecological noise protection wall with wedge-shaped noise protection elements made of straw thus offers a high level of economy in terms of sound, visual and financial aspects for reducing and avoiding environmental pollution caused by noise.
  • the wedge-shaped sound-absorbing elements can be arranged vertically or horizontally.
  • the wedge-shaped sound-absorbing elements are preferably stacked horizontally cassettes above each other and each provided with a roof.
  • each horizontally arranged, wedge-shaped sound-absorbing element is at its upper wedge surface provided with an arranged at an angle shingles and protected against weather conditions.
  • a further increase in noise reduction can be achieved by a weather-resistant and sound-absorbing surface coating of the roof shingle.
  • the roof shingle can be used in a conventional manner for attaching solar modules.
  • the lower side surface of the wedge-shaped Schallschluckiatas of straw is provided according to a further embodiment of the invention with a perforated cover.
  • the perforated cover is preferably made of a flexible, perforated or textile membrane to withstand the pressure loads on railways with high speed trains to maintain the mold.
  • the wedge-shaped sound absorption elements are fixed together with the roof shingle and the cover on a support plate, which preferably consists of untreated larch wood, which is similarly well suited in terms of ecology and durability.
  • an ecological noise protection wall is shown in lightweight construction, which is composed of individual wedge-shaped Schallschluck instituten 1.
  • the wedge-shaped sound absorption elements 1 are stacked like a cassette between vertical supports 2.
  • the vertical supports 2 are formed by double T flange carriers or two U - carriers, which are anchored in foundations 3 in the ground.
  • the double T-flange carrier have a U-shaped post chamber 4, in which the wedge-shaped sound-absorbing elements 1 are inserted from above.
  • the noise protection wall can be provided with a roof as a whole and, in addition, can be equipped with a splash guard in the lower area.
  • the noise barrier can be provided with a plant vegetation not shown, whereby the sound-absorbing effect, the climatic influence on the environment and the aesthetic effect are significantly increased. Through plant growth, the aging resistance of the noise barrier can be increased because precipitation and moisture are kept away by the vegetation.
  • a wedge-shaped soundproofing element 1 shown in FIG. 2 has a roof shingle 6 made of wood as a roofing for the weather protection.
  • the roof shingle 6 is inclined at an angle of approximately 45 degrees.
  • each wedge-shaped sound-absorbing element 1 is provided on its upper wedge surface with a roof shingle 6 and protected against the effects of weather.
  • the sound waves impinging on the roof shingle 6 are reflected by the angle of incidence on the lower side surface 7 of the wedge-shaped sound-absorbing element 1 and absorbed by the sound-absorbing substance 8.
  • the reverberant inner surfaces of the sound absorption element 1 can be provided with a sound-absorbing coating.
  • the sound-absorbing material 8 consists mainly of straw, stalks or fibers of plant origin. Under straw are the stalks of cereals to understand, while under stalks are essentially to understand the stems of the grasses. As stalks, for example, the stems of bamboo, rice and sugar cane are called.
  • Natural fibers of plant origin are, for example, cotton fibers or nonwovens of cotton, coconut, hemp, flax and cellulose fibers and cellulosic Fibers like bamboo fibers.
  • animal fibers such as sheep's wool can be used as Schallschluckstoff 8.
  • the invention should not be limited to the renewable raw materials mentioned in the exemplary embodiment.
  • other natural insulation materials suitable for noise protection can be used. These include inorganic insulating materials or sound-absorbing materials such as glass wool, mineral wool, rockwool or slag fibers and felt products which cause sound absorption.
  • Schallschluckstoff 8 can likewise be used for particles processed wood, wood wool and small pieces of wood chips and cellulose particles.
  • the lower side surface 7 of the wedge-shaped Schallschluckiatas 1 in Figure 2 is provided for wind protection with a perforated soundproof cover 9.
  • the perforated cover 9 is to maintain the mold preferably made of a flexible, perforated or textile membrane that withstands the pressure loads on railways with high-speed trains.
  • a sound-transmitting or sound-absorbing fabric for example, a coarse plastic fabric or glass fiber fabric may be used.
  • a flexible cover 9 is a variety of materials into consideration. These may consist of an air-permeable, soft or limp-set plastic or of textile materials which are provided with a corresponding impregnation.
  • a wide-meshed fabric comes into consideration when the meshes are smaller than the tubular particles of straw or stalks, so that they are prevented from falling out.
  • Films should have a low basis weight and have sufficient sound transmission, so that the absorption capacity of the noise barrier is not permanently impaired.
  • the shape of the air passage openings is arbitrary. They can be configured slot-shaped or hole-shaped.
  • a perforated cover 9 may likewise be formed of a different material such as metal or aluminum.
  • a perforated cover 9 may likewise be formed of a different material such as metal or aluminum.
  • the sound-absorbing material 8 in a one-piece molded cladding made of aluminum or another desired metal and to protect against the weather.
  • the wedge-shaped sound-absorbing elements 1 according to FIG. 3 with the roof shingle 6 and the cover 9 are mounted on a support plate 11.
  • the support plate 11 is preferably in the aspect of ecology from untreated larch wood, which has a good suitability for these purposes durability.
  • resistant larch - heartwood is used, which has a lasting decades lasting durability without environmentally harmful preservative with a proper structural protection.
  • individual sound-absorbing elements 1 should become unusable over time, they can easily be replaced by hand and disposed of in an environmentally friendly manner.
  • no hoists are required.
  • Other resistant types of wood are, for example, native hardwood such as oak or the Canadian softwood robinia.
  • native softwood species with usually more limited resistance may be used. These are the native softwoods larch and Douglas fir. With additional constructive wood protection measures, the life of the wood can be extended.
  • the support plate 11 in the exemplary embodiment of the untreated larch - heartwood has at the upper side edge 12 a milled from the solid spring 13 and at the lower edge 15 a groove 13 corresponding to the groove 14.
  • the support plates 11 can be connected in this way by means of the tongue and groove arrangement form-fitting firmly together and soundproof.
  • the groove 14 at the lower edge 15 and the side groove 16 at the two lateral edges 17 a mounting relief for the insertion of Dämmst Shape 18 in the space between the artificial stones 5 and the supports second
  • the compression band is a pre-compressed polyurethane-based foam sealing tape that expands slowly after insertion into a joint and seals against the seam edges.
  • the compression band is provided with a self-adhesive layer. With the self-adhesive layer, the compression band is fastened in the groove bottom 19. Shortly before assembly, the protective strip 20 of the compression band can be removed. After assembly, the compression band can expand. The joints between the supports 2 and the gap between the artificial stones 5 can thus permanently against sound be sealed. In this way, the assembly is facilitated by the delayed expansion of the compression band in the groove 14.
  • the wedge-shaped sound-absorbing elements 1 are inserted according to Figure 2 in the direction of arrow 21 in the post chamber 4.
  • the wedge-shaped sound-absorbing elements 1 are thereby held between the supports 2.
  • corresponding chamber woods 22 may be provided in the post chamber 4. If the support plate 11 is laterally reinforced in the region of the post chamber 4 with a chamber wood 22, a solid overall structure of the noise protection wall can be achieved. Robinia or oak is used for the chamber wood, which is better suited for the mechanical loads on high-speed lines.
  • the wedge-shaped sound-absorbing elements 1 can be arranged on the front side and the rear side of the support plate 11.
  • the wedge-shaped sound absorption elements 1 are easy to stack due to the geometric design.
  • the horizontally stacked wedge-shaped sound-absorbing elements 1 shown in FIG. 5 require a small space requirement during storage and during transport when being marketed. In this way, noise barriers can be built without much effort and at a low cost.
  • the wedge-shaped sound-absorbing elements 1 have an extremely low weight compared to conventional soundproof walls.
  • the noise barrier can be built along railway embankments and car terraces, even on difficult to access sections without heavy hoists and without interrupting the traffic.
  • the noise barrier wall of wedge-shaped sound-absorbing elements 1 has no joints or weak points with respect to a proper sound absorption.
