Definitions

  • the invention relates to a soundproofing element with at least one in the position of use of the sound source facing insulating layer of tubular plant material and at least one remote in the position of use of the sound source layer of a curable binder.
  • the invention relates to a method for producing such a soundproofing wall with at least one in the operating position of the soundproofing element of the sound source facing Dämm Anlagen of tubular plant material and at least one in the position of use of the soundproofing element of the sound source facing away layer of a curable binder.
  • noise protection One of the central tasks of environmental and health protection is noise protection. Acoustic emissions, such as those caused by the vehicles driving along them along motorways or rail routes, place a high burden on neighbors. Structural measures, in particular soundproof walls, can effectively protect residential areas along such routes from noise. In this case, the height, material and distance of the noise protection wall to the sound source with regard to a good insulation effect of great importance. The material used and the surface condition of the same on the sound source side facing determines whether the incident sound is mainly absorbed or reflected.
  • noise protection wall Depending on the material used for the noise barriers, the absorption rate and service life of the noise protection wall as well as production costs are very different. In terms of ecological construction, it is desirable to use resource-conserving and possibly renewable building materials and to abstain from toxic or otherwise harmful substances. At first glance, wooden noise protection walls fulfill these requirements, but in practice, the wood must be provided with chemicals to extend the service life, which means that it can not be used without hesitation.
  • reed as a sound absorber is for example from the German Utility Model 92 12 474.7 known. It describes a soundproof wall which, in a kind of sandwich construction, contains sound-absorbing material between two wall elements, preferably waste material or excavated material from ground works. On the wall elements reed mats o. ⁇ . Are fixed in one or more layers on at least one side as sound insulation.
  • the basic structure is any stable construction. The disadvantage, however, is the relatively high cost of building such a wall that can not be delivered and set up virtually prefabricated, but must be built on site.
  • Object of the present invention is therefore to provide a soundproofing element of the initially mentioned kind, which has very good sound-insulating properties, consists of environmentally friendly materials and is inexpensive to manufacture.
  • an above-mentioned soundproofing element in which the at least one insulating layer of tubular plant material and the at least one binder layer are arranged in a frame made of wood, which and at least one binder layer is at least partially pressed into the at least one insulating layer.
  • the at least one insulating layer of tubular plant material takes from the sound source originating sound and absorbs it to a large extent.
  • tubular plant materials for the insulating layer for example, reed, straw or bamboo come into question. These materials are very well suited for soundproofing, as they have excellent sound absorption due to their structure. In addition, such materials are often available in sufficient quantity and are therefore very inexpensive to purchase. Also, tubular plant materials can be processed relatively easily.
  • the at least one binder layer prevents the sound from passing through the soundproofing element.
  • the binder layer partially pressed into the insulating layer gives the insulating layer the requisite stability and strength which would not be present with the tubular vegetable material alone.
  • the combination of at least one such insulating layer and binder layer good sound insulation values can be achieved even with small thicknesses of sound insulation elements and thus low production costs and low weight. Since such soundproofing elements, as they are arranged in the form of noise barriers, for example, along motorways and train routes, constitute large attack surfaces for winds, a frame made of wood for reinforcement is arranged. By such a framework, the transport of the entire soundproofing element is considerably simplified and also speeds up the installation at the site.
  • At least one strip can be arranged on each side of the frame. By attaching one or more such strips falling out of the layers is prevented.
  • connection of the strips can be formed for example by threaded rods and corresponding nuts.
  • pressing of the layers can also be carried out without tools.
  • reeds absorb the sound very well, mainly because of its structure, it is advantageous if at least one insulating layer consists of this material.
  • reeds are considered to be largely rot-proof and is a low-cost, renewable resource that is easy to process and biodegradable.
  • the binder layer is preferably made of the environmentally friendly building material loam.
  • other pasty materials such as cement slurry, concrete or the like can be used.
  • the frame of the soundproofing element is usually exposed to high stress from the weather, it is advantageous if this consists of heat-treated wood, since such a treated wood is more resistant and thus more durable.
  • the use of chemicals for impregnation can be dispensed with in heat treated wood.
  • At least one further insulating layer on the side of the binder layer facing away from the operating position of the sound source.
  • This additional layer also has the function of protecting the binder layer from the effects of the weather, in particular moisture.
  • the at least one further insulating layer is likewise formed from vegetable tubular material, in particular reeds.
  • the at least one further insulating layer may be formed of cork, since cork is also a renewable raw material and has good sound insulation properties.
  • the additional insulating layer of hemp can be formed.
  • the at least one insulating layer is treated with a fire retardant, preferably an intumescent agent in the event of fire.
  • At least the outer insulating layer is preferably arranged so that the tubular plant material of the insulating layer is oriented substantially vertically in the position of use. This allows rainwater to run better and not penetrate deeper into the layer. In addition, such an arrangement provides for improved stability.
  • the tubular plant material of superimposed insulating layers can also be at an angle, preferably of substantially 90 °, be oriented to each other. This crosswise arrangement further increases the stability and also reduces the sound transmission.
  • the insulating layer facing the sound source consists of reeds with a thickness of 20-120 mm, the binder layer of clay with a thickness of about 3-20 mm and the further insulation layer of reed with a thickness of approx. 10-60 mm, as in this area an optimal ratio between the respective layer thicknesses and the achieved sound absorption is achieved.
  • practical experiments were carried out using loam as a binder and reed as a tubular plant material.
  • a cover element connected to the frame with openings for receiving the sound, at least on the side facing the sound source in the position of use.
  • the cover is formed by lamellar spaced from each other arranged strips.
  • a louver-like arrangement of slats obliquely to the vertical direction can also drain rainwater better.
  • the cover may be formed by a perforated plate.
  • the object of the invention is also achieved by an above-mentioned method for producing a soundproofing element, in which the at least one insulating layer is arranged in a frame made of wood, then a layer of the curable binder in liquid or pasty form on the in the position of use the soundproofing element of the sound source side facing away from the at least one insulating layer is applied, and the binder layer is pressed in still liquid or pasty form in the insulating layer.
  • the sound insulation elements described above can be relatively quickly and inexpensively. When pressing the binder this penetrates between the individual elements of the tubular material and acts after curing as a barrier to the sound and additionally as a reinforcement for the insulating layer.
  • the layer of curable binder may conveniently be sprayed onto the insulating layer.
  • the curable binder can be brushed onto the insulating layer with the aid of a suitable tool. Both methods allow a uniform application of the binder on the entire surface in a short time.
  • At least one further insulating layer can be arranged on the side facing away from the soundproofing element in the position of use of the soundproofing element.
  • An optimal reinforcement is achieved in that the at least one insulating layer, the at least one binder layer and any other insulating layers are pressed using both sides of the frame arranged strips.
  • the at least one insulating layer and any further insulating layers can be treated with a fire retardant, preferably an intumescent agent in the event of fire.
  • the at least one insulating layer and any further insulating layers are treated with a pest-protecting agent.
  • the attachment to the in the position of use of the soundproofing element of the sound source side facing a Abdeckelements with openings for receiving the sound not only improves the sound insulation, but also offers the opportunity to achieve a visually appealing solution.
  • the protection against the weather, especially rainwater, can be improved.
  • Fig. 1 is a soundproofing element 1 as seen from the sound source in side view.
  • the soundproofing element 1 has a frame 4 made of wood, in which at least one insulating layer 2, 2 'of tubular plant material and at least one layer 3 of a curable binder are arranged.
  • the frame 4 is preferably made of heat treated wood, so that it withstands the weather longer.
  • the embodiment shown consists of two insulating layers 2, 2 'facing the sound source in the position of use of the soundproofing element 1 and a further insulating layer 2 ", which is arranged on the side facing away from the sound source.
  • the tubular plant material of the outer, the sound source facing insulation layer 2 ' is arranged substantially vertically. This gives the soundproofing element 1 a higher stability and also facilitates the drainage of rainwater.
  • the insulating layer 2 arranged behind it has an orientation which is rotated by 90 ° with respect to the insulating layer 2 ', ie the tubular, vegetable material is orientated substantially horizontally.
  • the binder layer 3 for example made of clay, is partially pressed into the insulating layer 2.
  • a further insulating layer 2 '' is arranged, in which the binder layer 3 may also be pressed.
  • the frame 4 surrounds the insulating layers 2, 2 ', 2 "and the binding agent layer 3 and gives the soundproofing element 1.
  • a corresponding stability is provided by the strips 5 arranged on the outside of the frame 4, causing the insulating layers 2, 2', 2 '' and the binder layer 3 is prevented from the frame 4.
  • the opposing strips 5 can be connected to one another, for example by means of threaded rods 6 and corresponding nuts 7. In this way, the insulating layers 2, 2 ', 2 "and binder layer 3 can be pressed.
  • Fig. 3 shows a sectional view through a preferred embodiment of a soundproofing element 1 consisting of two in the use position of the sound source facing insulation layers 2, 2 'of reeds with a total thickness d 1 of 100 mm, a binder layer 3 of clay with a thickness d 2 of 10 mm and an insulating layer 2 "facing away from the sound source in the position of use, with a thickness d 3 of 20 mm, with such a soundproofing element 1 with a total thickness d of approximately 125 mm (by the pressing of the clay reduces the calculated total thickness of 130 mm) insulation values of 29 dB could be achieved.
  • Fig. 4 shows a sectional view of a multi-layer acoustic insulation element 1, wherein two binder layers 3, 3 'between three insulating layers 2, 2', 2 '' are arranged.
  • the binder layer 3 is partially pressed into the insulating layers 2, 2 'and the binder layer 3' partially in the insulating layers 2 ', 2''.
