Definitions

  • the invention relates to a sound-absorbing building board for cladding interior walls, in particular to a ceiling plate, with a carrier layer made of a perforated carrier plate with holes distributed over the entire surface of the carrier plate and sound-absorbing material lying on the carrier plate.
  • Sound absorbing building boards are used where the acoustic conditions of a room are to be influenced.
  • the most widespread use is as a ceiling panel, although sound-absorbing wall panels are also installed.
  • ceilings made of sound-absorbing building boards one also speaks of acoustic ceilings. If we speak of acoustic ceilings in the following, these explanations also apply to acoustic wall cladding.
  • the first main type uses porous board bodies, such as chipboard or mineral fiber boards. These panels themselves are sound absorbing and can be used to produce an acoustic ceiling without additional sound absorbing devices.
  • the plates are self-supporting and can be manufactured with relatively large dimensions due to their load-bearing capacity. It is also known to build such sound-absorbing structures to cover plates on their visible side with a microporous film, as described in DE-PS 1 053 173.
  • the microporous film generally does not have the task of improving the sound-absorbing properties of the carrier plate, but rather serves to achieve a different surface structure without simultaneously taking into account the sound-absorbing properties, since sound-absorbing plates do not always fully meet architectural requirements if there is no visible side covering .
  • the plate can also be made washable by applying a microporous film which is provided with a porous coating.
  • perforated carrier plates which can consist of both metal and non-metallic materials, such as gypsum, wood, in particular plywood or asbestos cement. These panels are not sound-absorbing themselves.
  • the sound absorption is brought about by a relatively thick layer of sound-absorbing material, for example mats made of glass fibers or of asbestos fibers, which is placed on the back of the plate.
  • the sound waves penetrate the holes and are dampened in the sound-absorbing material.
  • a disadvantage of this type of acoustic ceiling is that the sound-absorbing material becomes dirty over time and there is no possibility of cleaning.
  • the sound-absorbing material When removing individual ceiling panels, the sound-absorbing material must also be removed, which is often associated with partial destruction of the material and the corresponding amount of dirt, especially when large mats cover several panels. Even without repairs, particles of the sound absorbing material can fall out through the holes. A de Contamination of sound absorption material that lies behind the panels is not possible. In the production of acoustic ceilings there is the disadvantage that the laying of the sound-absorbing material is associated with the development of dust, which can also be harmful to health, especially when processing asbestos fiber material.
  • the disadvantages of the types of plates described are avoided with a building board according to DE-OS 29 30 123.
  • the building board described there has a carrier layer made of a perforated metal sheet.
  • the sound-absorbing layer is arranged on the visible side of the metal sheet and is firmly connected to the metal sheet, the sound-absorbing layer having a thickness of at most 5 mm.
  • the sound absorbing layer is only effective in the area of the holes. Since the total area of all holes is in any case significantly smaller than the total area of the plate, the sound-absorbing layer is only partially used.
  • the invention is based on the object of designing a sound-absorbing building board of the type mentioned above in such a way that a maximum of sound-absorbing effect is achieved with a minimum of sound-absorbing material.
  • sound-absorbing material is essentially only where it is acoustically effective, namely in the holes in the carrier board.
  • the sound absorbing material contained in the holes is fully utilized for sound absorption, so that the desired sound damping effect is achieved with a minimum of sound absorbing material.
  • Filling the holes also has the advantage that the ceiling tiles are dustproof so that they cover the space below the construction can protect plates from dust.
  • the sound absorbing material has a good hold within the holes.
  • Sound-absorbing material according to claim 2 is particularly advantageous. Such material can be introduced into the holes and then solidifies.
  • a thin layer on the back makes it easier to fill in the holes, since it is possible to coat the entire back with sound-absorbing material and from this layer the holes are filled.
  • a visible side layer is preferably arranged on the front side of the carrier plate (claim 4).
  • Such a layer has the advantage that the perforated pattern on the visible side is invisible and can therefore meet any architectural requirement.
  • the visible side layer can in turn consist of the same material as the hole filling and is then thin from the point of view that sound-absorbing material that is not arranged in the area of the holes has no acoustic effect anyway.
  • the visible side layer can also consist of a different material than the hole filling (claim 6).
  • an acoustically transparent film can be used (claim 7) or the visible side layer can be made of an applied mass, e.g. a paint or filler.
  • a protective layer can be arranged on the back, which consists of a different material than the hole filling (claim 9).
  • a protective layer can, for example Serve corrosion protection.
  • the acoustic flow resistance advantageously increases from the front to the rear. This can be achieved, for example, by using layers with different resistances (claims 11 and 12). Acoustic resistance increasing from front to back has the advantages that the absorption properties. the plate can be improved.
  • the carrier plate can be made of any material that gives the building board an overall sufficient strength.
  • Metal sheet is particularly suitable (claim 13).
  • thicknesses come into consideration, as specified in claim 14.
  • the carrier plate can also consist of non-metallic materials (claim 15), in which case greater thicknesses are possible than when using sheet metal, namely thicknesses as specified in claim 16. Even a relatively thin sheet of metal results in a sufficiently thick layer of sound-absorbing material within each hole.
  • the holes it is also possible for the holes to be filled with sound-absorbing material only over part of their length.
  • acoustic flow resistance Areas for the acoustic flow resistance of the sound-absorbing material are given in claims 17 and 18.
  • DIN sheet 52 213 For the concept of acoustic flow resistance, reference is made to DIN sheet 52 213 from December 1958.
  • the required flow resistance can be achieved in different ways. In the case of a thick layer of sound-absorbing material, as can be considered, for example, in the case of carrier plates made of non-metallic material, a sound-absorbing material of relatively high specific permeability can be selected, in which case the desired acoustic flow resistance is created by a larger layer thickness. If a thinner backing plate is used, one usually becomes one Use sound-absorbing material that has a greater flow resistance in relation to the thickness.
  • the ceiling construction according to FIG. 1 has as a support device for ceiling panels 1 a system of band grid profiles 2 and 3 arranged at right angles to one another. Square band fields are formed by these band grid profiles and are filled by the ceiling panels 1.
  • the plate shown has a square plan shape and is profiled so that it forms a four-sided pyramid with the inclined surfaces 4 to 7 (see also Fig. 2). The surfaces 4 to 7 meet at edges 8 to 11. At the edges, the plate has upward bevels 12.
  • the shape of the plate can be any.
  • a flat plate 13 is shown, which also has a square plan shape and edge bends 14.
  • Two diagonal beads 15 and 16 extend across the plate, which serve to stiffen the plate, but are covered from the visible side.
  • the invention is not concerned with the basic shape of the plates described, but with their structure, which will be described below with reference to FIG. 4.
  • the plate 13 (correspondingly also the plate 1 according to FIG. 2) has, it is assumed in the exemplary embodiments discussed with reference to the drawing, a carrier layer 17 in the form of a perforated sheet.
  • the perforated sheet 17 is pierced by many holes 20, the arrangement of which can be seen from Fig..5.
  • Fig. 5 shows that the holes 20 are evenly distributed.
  • the pattern of the distribution may differ from FIG. 5.
  • the hole arrangement and the hole size can vary within wide limits.
  • the proportion of holes, ie the total area of all holes, can be in the range from 4% to 40% of the total area of the plate.
  • the thickness 5 ; of the sheet depends on the material of the sheet, the percentage of holes and the overall size of the sheet. A common thickness when using sheet steel is 1 mm.
  • the holes 20 are filled with a sound-absorbing material 21.
  • a layer 22 made of the same material with which the holes are filled.
  • the thickness s 2 of this layer is small. Only the parts of the layer 22 which lie within the edges of the holes 20 have a sound-absorbing effect.
  • the thickness s 2 can be, for example, 0.5 mm.
  • the sound-absorbing material 21 and the layer 22 can be designed in accordance with DE-PS 1 053 173, i.e. a preferably non-combustible fibrous support, e.g. in fleece or fabric form, which is mixed with a mixture of substances forming open micropores during hardening.
  • the plate is preferably to proceed in such., That first the beading 15, 1 6 are mounted. The beads extend upward, so that there are no projections on the visible side formed by the layer 22 are available. The sound-absorbing material is then applied to the plate while it is still malleable. So much material is added that all holes 20 are filled and then there is still a residue for the formation of layer 22. After the sound-absorbing material has hardened, the edge folds 14 are produced. Then the plate can be painted on its visible side (in Fig. 4 below).
  • the thin layer 22 forms a smooth outer surface.
  • the cavity 15 ' which forms the bead on the underside of the sheet metal plate 17, is filled by the sound-absorbing material and is accordingly not visible.
  • Fig. 6 shows the area of the edge bend 14. At this edge bend there is a bend 21 of 90 °. Tearing of the layer 22 in the bend area is avoided if the bend is either made before the layer is applied or the layer is only solidified (after it has been applied before the bend) when the bend has been made.
  • Fig. 7 shows a partial section through a plate designated overall by 23, which is composed of two or more sheets 24 and 25.
  • the sheets 24 and 25 have edge folds 24a and 25a which are connected to one another, e.g. by spot welding.
  • the joint 26 on the underside is also filled with sound-absorbing material 22 and is therefore not visible.
  • the plate according to FIG. 8 is designated 27 overall.
  • This plate also has a support 28 in the form of a hole ten sheets.
  • a support 28 in the form of a hole ten sheets.
  • This embodiment is suitable if the requirement is not made that the hole pattern on the visible side of the plate should be invisible.
  • the sound-absorbing effect is very good, since only the sound-absorbing material that is in the area of the holes is involved in the sound absorption.
  • the plate 31 according to FIG. 9 in turn has a carrier 32 in the form of a perforated sheet.
  • the holes 33 are filled with sound-absorbing material 34.
  • This embodiment is inexpensive to manufacture. The production can be carried out by pouring a certain excess of material onto the back of the metal sheet 32, so that complete filling of the holes 33 is ensured and the layer 35 is formed from the excess material.
  • the plate 36 according to FIG. 10 also has a carrier 37 in the form of a perforated metal sheet.
  • the holes 38 are filled with sound-absorbing material 39.
  • This material 39 forms on the back a thin layer 40, ig, as well as in the embodiment of F. 9.
  • a further layer 41 which consists of a different material than the hole filling.
  • the layer 41 can be formed by a lacquer.
  • Embodiments are also possible in which a visible side layer and a rear side layer are made of another Material consists of the material with which the holes are filled. It is advantageous here that the visible side layer has a relatively small acoustic flow resistance, the hole filling has a greater acoustic flow resistance and the rear side layer has an even greater acoustic flow resistance. This brings the advantage mentioned in the introduction to the description.
  • a visible side layer can be completely transparent acoustically, so it only has the task of giving the visible side a desired appearance. The sound attenuation then takes place exclusively above this layer, mainly in the material that fills the holes in the metal sheet.
  • An acoustically transparent material is e.g. a thin plastic film, e.g. with a thickness of 0.02 mm or less.
