Definitions

  • the invention relates to a sound absorption element, consisting of a body held by a carrier made of foam, preferably polyurethane foam, which is provided with a smooth or with an elevation and depression profile outer surface.
  • Such a sound absorption plate is known as a sound chamber closure, etc. for a sound chamber, formed from the web walls and the rear wall of an E-shaped concrete block, which is used to build sound insulation walls.
  • the profile outer surface is formed from rib fields running orthogonally to one another, and a continuous stiffening plate, on one or both sides of which the foam layer is arranged, serves as the carrier.
  • the invention has for its object to provide a simple and inexpensive sound insulation system that is used in industry and trade, but also in sports halls, gymnasiums, music schools and the like. can be used universally, both in old and new buildings, etc. for room noise reduction.
  • the sound absorption element of the type mentioned at the outset is characterized in that the carrier is formed by a lattice work, preferably made of wire, which is connected to the foam body and supports it at least at edge zones.
  • Wire or steel lattice works are in themselves in construction, e.g. as a carrier for plaster or shotcrete layers, known for a long time.
  • flat and round absorbers can be produced in a simple manner in the manner according to the invention; particularly advantageous in that the latticework is glued to the profiled foam body. It is preferably provided that the latticework extends over the entire surface of the profiled foam body; in some cases it may be sufficient to arrange the support only in an edge area of the element.
  • Another feature of the invention is that parts of the latticework, preferably on opposite sides of a plate-shaped profiled foam body or on the End faces of a roller-shaped profiled body, protrude above the profiled body to form anchoring parts; these protruding wire ends enable particularly simple fastening of the elements, in particular in a framework consisting of known U-profiles, in the web and leg parts of which rows of holes are formed, the anchoring parts of the elements being able to be brought into engagement with holes in these rows of holes.
  • both types of absorbers can be hooked into the holes of the U-profiles with the same mounting distance, it being possible for the flat absorber to be arched by a prestress.
  • both types of absorbers are suitable for horizontal and vertical installation.
  • the absorbers By mounting on the U-profiles, the absorbers can be hung at any distance, and all structural conditions can be taken into account. Furthermore, these U-profiles can be used to attach lighting fixtures and other installations, which saves costs.
  • wire grids or other wire baskets as supports, practically all visual and design wishes can be met, and furthermore, the wire grids have a safety advantage that should not be underestimated in the event of a fire, since the flame-retardant foam cannot fall prematurely on fire-fighting teams when exposed to heat.
  • Dirty absorbers can be removed and cleaned in a short time thanks to the simple suspension, e.g. vacuumed off, and sprayed again with a special paint or impregnating agent.
  • the round absorber 1 consists of a cylindrical lattice work in the form of a wire basket 2, comprising circularly curved wires 3 and perpendicular wires 4.
  • U-profiles 7 can (in a manner not shown) form scaffolds for holding the elements 1, depending on the requirements.
  • an absorption material Specially treated, for example flame-retardant and / or bacteriostatically equipped foam 10 is glued on with a curled surface, and the two openings of the basket 2 on its end faces are closed with a foam layer 10 ', as can be seen in FIG.
  • the flat absorber 11 shown in Figure 3 consists of a wire mesh 12, with. horizontal wires 13 and vertical wires 14 and with wire ends 15 projecting on each narrow side on the end wires 14 '.
  • This grid 12 is glued on both sides with foam plates 20, which are curled.
  • the lower end 15 of the wires 14 ' can be bent at right angles, which results in a secure fixing in the U-profile 17.
  • the wire ends 5 serving as anchoring parts are of different lengths on different sides of the element, above and below. Due to the different length of the wire ends, the hanging is and fixation of the absorber possible with rigidly mounted hangers formed by the U-profiles.
  • the round absorber is pressed with the longer wire ends upwards or laterally up to the wire cylinder against the perforated profile, and then the absorber is brought into the horizontal or vertical position and engaged on the opposite side with the two shorter wire ends.
  • the foam absorption material 20 is expediently glued above the wire cylinder on one side above or below, preferably on the side with the longer wire ends, as can be seen from FIG. 4, so that this protruding foam material takes on a spring effect and pushes the absorber back into the correct position or fixed in this position.
  • the material 20 can also be connected to the lattice work by riveting or stapling. Instead of a nubbed profile outer surface, it can also have a corrugated or smooth surface.
  • any distance from absorber to absorber can be maintained or achieved, taking into account the structural conditions and the respective requirements for elements necessary for sound insulation.
  • the absorbers can be bent by bending the wires "the 15 according to Figure 4 are secured in one direction and at a right angle, without this affecting the hanging and unhooking of the absorber plates 11.
  • Such a fuse is advantageous in the construction of cabins, shielding or partition walls and the like.
  • the foam 20 can be left on both long sides horizontal installation of the flat absorbers also a closed surface made of foam absorption material can be obtained.
  • the elements can of course also be in the form of cubes, pyramids, cones or the like. be made.
  • the lattice may not only have orthogonal fields as shown, but also triangular or others.
