Definitions

  • the present invention concerns a dividing wall element in accordance with the preamble of Claim 1 hereinbelow.
  • Such dividing wall elements are for the most part constituted by gypsum plaster boards arranged at a certain distance from each other, possibly with a filling of heat insulation material.
  • Such dividing wall elements are preferably used as room partitions and are distinguished by their light-weight structure and the speed with which they can be installed.
  • Such dividing wall elements are therefore very often used for interior finishing work and in this connection have to comply with a series of criteria, namely compact and simple structure, ease of fabrication, stability, and quick and easy installation.
  • the prior art document DE-26 11 033 discloses a fire-protecting wall with outer walls of gypsum and internal layers of mats of fibre such as mineral wool.
  • the document FR 1 576 287 discloses a dividing wall for noise-insulating with several layers, which are separated by flat rods and which has a paper structure in the middle.
  • the present invention sets out to design a dividing wall element for use as a room partition with excellent sound insulation properties, with a simple design and economic as far as costs are concerned.
  • the filling between the outer skins which are generally made of gypsum plaster board, consists of a sandwich arrangement of several layers of insulating materials, each differently specified as regards its heat or sound absorption capacity and / or its elastic behaviour.
  • the multi-layer filling is particularly character ized by the fact that at least one layer of insulating material that is in direct contact with the outer skin, but preferably both layers of insulating material adjacent to the outer skins, is / are coupled with the outer skins - which are especially made of gypsum plaster board - as far as oscillation behaviour is concerned.
  • This oscillation coupling of the outermost insulating layers is preferably obtained by designing the inner insulating layers with good elastic properties, so that upon incorporation between the outer skins they will build up restoring forces that act on the insulating layers adjacent to the outer skins, i.e. the two outermost insulating layers, and press them permanently against the outer skins. In this way one assures that the outer filling layers will oscillate with the outer skins, which has the effect of conferring excellent sound insulation properties upon the dividing wall element.
  • the inner layer is made of a material with a porous and / or open structure, namely mineral wool, and preferably a material with a small gross density in the range between 14 and 25 kg/m 3 , preferably between 16 and 18 kg/m 3 , especially 17 kg/m 3 , which leads to a very considerable elastic capacity of the layer and the building up of appropriate restoring forces when the sandwich structure is incorporated between the outer skins.
  • the outer filling layers i.e.
  • the layers adjacent to the outer skins are designed to be heavier than this inner layer, especially with a gross density in the range between 100 and 370 kg/m 3 , preferably between 150 and 185 kg/m 3 , especially in the range between 160 and 175 kg/m 3 .
  • the outer skins with the immediately adjacent layers are designed to be as heavy and resilient as possible.
  • the outer insulation layers will likewise be made of mineral wool. Preferably, however, these outer insulation layers should also have springy characteristics, since these are of advantage as regards the oscillation coupling and the sound absorption capacity.
  • the central insulating layer can also be designed as a multi-layer system.
  • the filling in accordance with the invention is accordingly made up of a mix of layers with good sound absorption capacity and substantial heat insulation, and this renders the dividing wall element suitable for being used in many different applications.
  • the dividing wall element can be advantageously constituted as a prefabricated element, more particularly, a composite element in which especially the outer layers of insulating material are attached to the two outer skins, possibly glued, and the insulating layers are also attached to each, preferably by gluing.
  • a kind of sandwich composite consisting of the central layer and the insulating layers adjacent to it more or less as a semi-finished product in which the individual layers are lying loosely in contact with each other and are kept together in a pre-stressed condition by means of band-like hoops.
  • the semi-finished product is then placed between the outer skins, after which the hoops are removed,, so that the pre-compression will keep the outermost layer of insulating material firmly in contact with the outer skins.
  • the dividing wall element 1 illustrated by the figure has two outer skins 2 and 3, which constitute the external surfaces of dividing wall element 1 and are for the most part made of gypsum plaster board. Between these outer skins or gypsum plaster boards 2, 3, which are separated by a certain distance, there is arranged a filling that in the example here illustrated consists of the layers, especially three layers of insulating material 4, 5 and 6.
  • the insulating layers 4 to 6 are preferably made of mineral wool.
  • the two insulating layers 4 and 6 adjacent to the outer skins 2 and 3 are so constituted as to be heavy as compared with the central insulating layer 5, but not to the point of being devoid of resilience.
  • the central insulating layer 5 is characterized by a comparatively great elasticity. More particularly, the elastic behaviour of the of the central insulating layer 5 is so chosen that upon inclusion between the adjacent insulating layers 4 and 6, the appropriately oversized central layer will be compressed and build up restoring forces, so that the two insulating layers adjacent to the outer skins will be permanently pressed against these outer skins.
  • the distance between the inner faces of the two outer skins 2 and 3 amounts to 100 mm.
  • the two outer insulating layers 4 and 6 are designed to have a thickness of 32 mm each, while the central insulating layer has a thickness of 40 mm, which means that, taken together, the three insulating layers are oversized by 4 mm, this oversize being compensated by compression of the central layer.
  • the two outer insulating layers 4 and 6 have a gross density of 175 kg/m 3
  • the central insulating layer 5 has a much smaller gross density of 17 kg/m 3 , i.e. the central insulating layer is characterized by a porous open structure as compared with the massive and heavy design of the outer insulating layers 4 and 6. Incorporation of the central insulating layer in the dividing wall element sets up restoring forces acting on the outer insulating layers 4 and 6, so that these will become acoustically or oscillationally coupled with the outer skins 2 and 3
  • the distance between the two outer skins amounts to 50 mm.
  • the two outer insulating layers will then preferably have a thickness of 12 mm each, while the thickness of the central insulating layer will once again amount to 40 mm.
  • the gross density of the two outer insulating layer in this case amounts to 160 kg/m 3 , while the central insulating layer has a density of 17 kg/m 3 .
  • the invention is not by any means limited to the two embodiments that have just been described and the particular values associated with them.
  • embodiments in which only one of the insulating layers adjacent to the outer skins is oscillationally coupled with its outer skin due to a design that confers an appropriately high elasticity upon the inner insulating layer or layers can also be advantageous.
  • outer skins 2, 3 to be constituted by gypsum plaster boards
  • sheet metal having a thickness of, say, 0.6 mm for the outer skins, in which case the overall thickness of the dividing wall element in accordance with the invention may be advantageously chosen in the range between 70 and 120 mm.
  • the single-layer filling with an insulating material having a thickness of 70 mm yielded a sound absorption characteristic R W of 43 dB independently of the gross density of the material and with flow resistances greater than 5 kPa s/m 2 .
  • the sound absorption characteristic R W was found to be reduced by 1 dB and had a value of 42 dB.
  • the multi-layer filling in accordance with the invention consisting of two outer insulating layers having a thickness of 22 mm each and a gross density of 195 kg/m 3 that were combined with a 20 mm thick central insulating layer having a gross density of 19 kg/m 3 , on the other hand, yielded a sound absorption characteristic Rw of 47 db.
  • the sandwich-type filling in accordance with the invention therefore improved the sound absorption characteristic Rw by up to 5 dB.
  • Comparable improvements were obtained in the tests performed on 100 mm thick CW profiles.
  • the flow resistance was set to at least 5 kPa s/m 2 in all cases.
  • the comparison values were determined as 46 dB with a single-layer filling having a thickness of 95 mm and a gross density of 27 kg/m 3 , and likewise as 46 dB when the thickness amounted to 80 mm and the gross density to 26 kg/m 3 .
  • a total of four multi-layer fillings in accordance with the invention were tested.
  • the sandwich-type filling in accordance with the invention therefore improved the sound absorption characteristic R W once again by up to 5 dB.
  • the central insulating layer may itself be structured as a multi-layer system. Particularly suitable are also fillings with four insulating layers or two insulating layers. When only two insulating layers are used, only one of the insulating layers will be acoustically coupled with the outer skin, i.e. designed as an appropriately heavy layer with a high gross density, while the other insulating layer will have a substantially smaller gross density and appropriately good elastic properties.
  • the central layer should have an appropriately porous and / or open structure and be capable of building up permanent restoring forces.
