Definitions

  • the invention relates to a soundproof wall according to the preamble of patent claim 1.
  • Soundproof walls which are used in various types of training, play a special role in passive noise protection measures. They usually have brackets to which the soundproofing elements are attached, which have been developed according to different criteria.
  • the soundproofing elements are made of different materials such as plastic, metal or glass and have different shapes. The shape plays an important role here, since it decisively determines the reflection and damping properties of the soundproofing elements.
  • the patent specification CH 671 054 A5 is based on this principle. Then two lightweight concrete layers are placed on a solid supporting plate, the uppermost pyramid-shaped elevations, which should show a particularly high absorption capacity.
  • This principle is expanded in patent specification DE 44 11 003 A1, in that the elevations are formed from other geometric bodies with a conical, truncated cone or prism-shaped cross-sectional structure, and in patent specification WO 98/26131 by a particularly dense arrangement of the elevations.
  • the invention has for its object to provide a soundproof wall of the type mentioned, which has an improved noise reduction compared to previous soundproof walls and is easy and safe to install.
  • the mixture of expanded glass or expanded clay on the one hand and cement on the other hand has a lower density than the mixtures usually used in the prior art for the at least one soundproofing element. This makes it possible to transport and store the protective wall according to the invention much more easily and with less effort than with conventional soundproof walls.
  • the at least one soundproofing element has an open-pore, highly porous layer and an adjoining porous layer or, alternatively, an open-pore, highly porous layer, an adjoining porous layer and another adjoining dense or porous layer , wherein the dense layer is made of potting material and the open-pore, highly porous layer is arranged facing the noise source.
  • the open-pore, highly porous layer has a large specific Surface and thus has numerous pores, which are available to absorb the sound. With the help of the porous layer or the further dense or porous layer, a soundproofing element is thus ultimately created which has a sufficiently high strength and is easy to process and process.
  • the open-pore, highly porous layer takes up about a quarter of the volume of the at least one soundproofing element and the porous layer takes up about half to three quarters of the volume of the at least one soundproofing element.
  • the soundproofing element according to the invention can thus also be produced in a few steps and thus extremely cost-effectively.
  • the at least one soundproofing element has at least one reinforcement, preferably made of steel or plastic, whereby according to a first embodiment the at least one reinforcement is provided between the open-pore, highly porous layer and the adjacent porous layer, or according to a further embodiment one first reinforcement between the open-pore, highly porous layer and the adjacent porous layer and a second reinforcement in the further dense or porous layer is provided.
  • the strength, in particular flexural and torsional strength, of the soundproofing wall according to the invention is further improved. This largely ensures that, even in high heat, not entire plate parts of the soundproofing element can fall off a ceiling, for example, but at most no pieces that cannot harm anyone.
  • the porous layer advantageously consists of a denser mixture of expanded glass or expanded clay with cement. This creates a simple possibility of ultimately producing the open-pore, highly porous layer and the porous layer using the same ingredients and merely changing the porosity of the material.
  • the porous layer and / or the further dense or porous layer is preferably reinforced with mineral or glass fibers by means of insulating strips.
  • the surface of the open-pore, highly porous layer is wave-shaped or provided with groove-shaped depressions.
  • the sound-insulating properties of the soundproofing wall according to the invention are further improved, such a soundproofing wall being able to be used primarily in the area of passenger traffic, in particular on motorways.
  • At least one mounting element is provided, by means of which the at least one soundproofing element can be fixed, wherein according to a first embodiment, the at least one mounting element has one or more screws which completely penetrate the at least one soundproofing element and with which the at least one soundproofing element can be fastened to a wall and / or a ceiling and / or to a pile-shaped support of the at least one support element, or according to another embodiment the at least one support element has an H-shaped or U-shaped support support and a tensioning device by means of which the soundproofing element can be fixed to the respective support beam.
  • the soundproofing element according to the invention can thus be easily attached to a wall or a ceiling or to a floor in such a way that the soundproofing element is held securely in its place even in the event of a fire. This applies in particular when the soundproofing wall according to the invention is used in tunnels.
  • the support beams mentioned it is also possible, for example, to mount the soundproofing wall according to the invention on roads or in the vicinity of noisy factory premises or on railway lines.
  • the tensioning device is a tensioning screw which partially penetrates the soundproofing element and which is screwed into the soundproofing element inserted into the support beam and braced together with the latter against the support beam. That’s it at least one soundproofing element is held securely in or on the support beam and is effectively prevented from sliding out of it.
  • a preferably continuous insulation made of plastic or special rubber is inserted between the soundproofing element and the support or between the soundproofing element and the support support of the at least one mounting element, which is preferably in the state of the at least one mounting element fixed to the at least one mounting element is pressed together.
  • the sound waves are thus prevented from passing through the space provided between the at least one mounting element and the soundproofing element.
  • the sound insulation of the soundproofing wall according to the invention is further improved.
  • Fig. 1 with horizontal cross sections through a soundproof wall
  • FIG. 2 shows horizontal cross sections through the soundproofing wall with two soundproofing elements (FIG. 2a) or one soundproofing element (FIG. 2b) per support as a holding element;

  • the H-shaped support beam 3 and the U-shaped support beam 4 form a mounting element 15 of the soundproofing wall 14, by means of which the at least one soundproofing element 1 can be fixed.
  • a continuous insulating band made of plastic or special rubber is inserted between each soundproofing element 1 and the respective support beams 3, 4 of the holding element 15.
