Definitions

  • the invention relates to a soundproofing element with the features according to the preamble of claim 1.
  • Sound insulation elements are used to create acoustic wall coverings in buildings to improve sound absorption, noise protection walls and the like.
  • the mainly acoustically effective sound-absorbing packing e.g. a mineral fiber fleece, arranged on the back of an acoustic tile (grid tile) so that it covers the holes opening there, and is held in place by a rectangular brick frame.
  • the shape and size of the brick frame is matched to the acoustic tile and with it, e.g. connected by gluing.
  • soundproofing elements with this design are attached to a wall that determines the size of the noise barrier.
  • a walling of the soundproofing elements in the association is desirable per se for structural reasons - and also prescribed according to DIN 1053 - however, for design reasons, a cross joint laying is regularly required. For these, however, a separate static proof of strength must be provided.
  • a soundproofing element of the type specified at the outset is known (DE-U 66 01 653), which is constructed in one piece, for example with mineral wool Has filled cavity and is delimited on one side by a perforated wall.
  • the production by means of the extrusion process makes it possible to manufacture the soundproofing element in different lengths, as a result of which the time required for bricking is reduced.
  • a disadvantage of this known soundproofing element is that, particularly when used as acoustic wall covering in the interior of buildings, it must be made of a very good quality ceramic material in order to avoid uneven shrinkage or warping during the firing process, which make the connection unsafe during processing and can also impair the external appearance that is important for such soundproofing elements.
  • the object of the invention is to propose a soundproofing element of the type specified at the outset, which permits simpler and therefore cheaper production and is simple Can be processed in association with visible cross joint.
  • the soundproofing element according to the invention can be bricked up in a bond with a visible cross joint, because a natural joint is created between the acoustic tiles, for example square, connected to the continuous U-shell.
  • the soundproofing element according to the invention is also advantageous over the known soundproofing elements with rectangular brick frames described at the outset. Because in that the holder in the soundproofing element according to the invention is no longer designed as a brick frame, but in the form of a flat U-shell has, a plurality of acoustic tiles, side by side or one above the other, combined with the continuous - and in this case approximately groove-shaped - U-shell to form a soundproofing unit and processed in this form. Such a procedure is not possible with the known soundproofing elements because the brick frames forming the holder for the sound absorbing pack are completely sealed off from one another.
  • the bracket formed by the U-shell does not completely enclose the sound-absorbing pack, but leaves it free on two opposite sides. However, this does not interfere with the functionality, because the sound-absorbing pack, which preferably consists of a mineral fiber fleece, has sufficient inherent rigidity that prevents it from falling out or swelling out.
  • the U-shell is expediently produced by the extrusion process, preferably ceramic material, e.g. Sound, is used.
  • ceramic material e.g. Sound
  • this method can be used to produce any length of the U-shell corresponding to the number of acoustic tiles to be arranged next to or on top of one another.
  • any other molding process e.g. for molded concrete parts, conceivable.
  • a soundproofing element essentially consists of at least two lattice tiles 1 with straight perforation or oblique perforation (FIG. 4), a sound absorption pack 2 covering the back of the lattice tiles 1 in the form of a plate made of a mineral fiber fleece and a holder 3 in the form of a U-shaped cross section.
  • shaped Shell which surrounds the sound absorbing pack 2 from above and below - in Fig. 3 - and whose U-legs 4 are glued with their front edges to the back of the lattice brick 1.
  • each lattice brick 1 has an approximately square shape and the dimensions of the U-shell 3 are adapted to this.
  • the sound absorbing pack 2 does not take up the entire space that is available between the rear of the lattice tiles 1 and within the U-shell 3. Rather, there is a free space 6 between the pack 2 and the plate-shaped web 5 of the U-shell 3, the size of which can influence the sound absorption capacity of the soundproofing element in a certain sense. However, it goes without saying that the space 6 can also be filled with another pack.
  • a plurality of lattice tiles 1 can be arranged next to one another and by an undivided U-shell 3 into one Unity.
  • the length of the U-shell 3 then corresponds to the total length of the lattice tiles 1 arranged next to one another.
  • the sound-absorbing pack 2 can be formed by a strip of an absorption material, the length of which also corresponds to that of the overall arrangement.
  • Such sound absorption units can be prefabricated and processed on the construction site, in a vertical or horizontal arrangement, considerably faster than the known soundproofing elements with a rectangular frame and in association.
  • the length of the U-shell can also be considered to choose the length of the U-shell to be greater than the total length of the acoustic tiles attached to it.
  • the protruding part of the U-shell or the like can be anchored in adjacent masonry. be used.
