Definitions

  • the present invention relates to a multi-layer, sound-absorbing structure covered with bulk-resistant plants for the production of sound-absorbing noise protection devices, such as sound-absorbing noise barriers or noise protection walls on highways and airports, for delimitation from residential and / or industrial areas.
  • the stone or glass wool is not only pressed, but also expediently laminated with a glass fiber fleece. It is important that the sound absorption capacity of the stone or glass due to the lamination do not want to experience any impairment.
  • a glass fiber fleece is used for the lamination, which is produced according to the so-called aerodynamic process and which consists of randomly arranged glass staple fibers and a binder based on a melamine-formaldehyde resin.
  • the glass fiber fleece is porous and remains permeable to water and air.
  • multi-layer, sound-absorbing structures covered with plants which consist of a plurality of structural elements offset from one another in the vertical direction and composed of two layers running parallel to one another.
  • One layer is formed from a non-combustible inorganic material, namely a loose fill of blast furnace slag, and the other layer is a substrate layer.
  • the blast furnace slag is completely or partially (basket-like) covered by a wire mesh.
  • the blast furnace slag is held together by the wire mesh.
  • the blast furnace slag absorbs noise because the sound gets caught in the spaces (indentations and channels) that are abundant in the loose fill.
  • the upper component is set back so far from the lower component that there is a distance, the surface of which is partially formed by the substrate layer in which plants grow.
  • the plants have a purely decorative task. In this way you want to ensure that the structure in the landscape is not disruptive.
  • the structures described can and will be used for cladding or cladding built to protect against noise or Walls used in residential or industrial areas.
  • the slag layer must be quite thick if you want to achieve a significant sound-absorbing effect.
  • the space available for the construction is limited in many ways, so that the thickness of the slag layer is limited.
  • the slag layer is gradually destroyed by weather influences, in particular ice and snow, and then has to be renewed.
  • the lifespan of such a structure is correspondingly short.
  • the subject matter of the invention is thus a multi-layer, sound-absorbing structure covered with bulk-resistant plants for the production of sound-absorbing noise protection devices outdoors, such as sound-absorbing noise barriers or noise barriers on motorways and airports, to differentiate them from residential areas or industrial areas.
  • the structure according to the invention is distinguished by an improved sound absorption capacity and an increased service life compared to the previously known ones.
  • the overgrowth with bed-resistant plants not only serves decorative purposes, but also forms an integral part of the structure according to the invention.
  • the bed-resistant plants which are preferably willow species, are pressed against the stone fiber layer and the heels by the wire mesh, which consists of rust-proof, preferably PVC-coated, spot-welded wire mesh. These roots take root where the plants come into contact with the surface of the stone fiber layer and the substrate layer of the heels. The roots penetrate both the S teinmaschine für and the substrate layer. A real network of roots forms in the structure, which gives the structure a natural hold.
  • the hold is further strengthened by inserting the plant shoots reaching the height of the following paragraph by bending or bending into the substrate layer of this paragraph and letting roots take root.
  • a real machining is created, as it has long been known for attachments for slopes and slopes. Machining is based on the property of the bulk-resistant plants to form roots wherever they are resisted on the surface and where food is offered.
  • Species of willow are particularly suitable for the growth of the structure according to the invention. These are not only characterized by a particularly high resistance to filling, but also by a great ability to regenerate. They heal quickly in the case of injuries, for example from stone chips, and they have the ability to form adventitious roots and new, complete plants from woody parts.
  • Wire mesh has the function of mechanically fastening the structure.
  • the wire mesh has a stabilizing effect and prevents the structure from collapsing under the snow load, particularly when the structure is exposed to special loads, for example in heavy snowfall.
  • the vegetation is extremely decorative and makes the structure appear like a natural hedge.
  • the vegetation can also be cared for like a hedge, i.e. be cut or trimmed.
  • the structure according to the invention thus proves to be extraordinarily landscape-friendly. In no way does it appear in the landscape as a foreign body.
  • the overgrowth of the structure is also environmentally friendly in that it absorbs pollutants, especially carbon oxides, from the environment and releases oxygen into the air.
  • the proportion of stone fiber layer to substrate layer on the surface of the heel is preferably 2: 1, the ratio of the width of the heel to the height of the individual stone fiber mats forming the stone fiber layer is preferably 1: 8 to 1:12.
  • the stone fiber mats generally have a height of 60-80 cm and a thickness of approximately 5 cm.
  • the wire mesh is convexly curved several times in the vertical as well as several times in the horizontal direction and likewise the stone fiber mats are convexly curved several times in the horizontal direction and simply in the vertical direction.
  • the stone fiber layer consists of pressed rock wool and is laminated on one side with a porous glass fiber fleece.
  • the glass fiber fleece preferably consists of randomly arranged glass staple fibers and a binder based on a melamine-formaldehyde resin, the proportion of the binder in the glass fiber fleece being 12-18%, has a weight per unit area of 50-100 g / m 2 and a porosity of 1000 - 3000 1 / m 2 / sec. according to DI N 53857.
  • the high porosity of the glass fiber fleece makes it permeable to water and air.
  • the sound absorption capacity of the rock wool is not affected by the lamination.
  • An adhesive based on a phenol-formaldehyde resin is expediently used as the adhesive for the lamination.
  • an approximately 20% aqueous phenol-formaldehyde resin solution is suitable.
  • the A ufkaschtechnik is done with conventional Kaschiervorraumen.
  • the working conditions such as lamination speed, drying speed, drying temperature etc., naturally depend on the special adhesive used.
  • the stone fiber layer as an inorganic natural product, is a particularly plant-friendly material and as such has the ability to store water, which is crucial for the viability of the plants.
  • the stone fiber layer also protects the substrate layer from drying out as a result of external weather conditions, such as winds and solar radiation.
  • the substrate layer is determined according to horticultural considerations or experiences. It preferably has a heterogeneous structure and, in addition to humus or soil, contains artificial materials which are indifferent to the plants and have a water-storing effect and, if possible, also have a sound-absorbing effect.
  • the substrate layer generally has a thickness of 15-30 cm.
  • One or more layers of bulk material follow the substrate layer.
  • a first layer of bulk material can consist, for example, of blast furnace slag and a second layer of bulk material can consist of a mixture of clay and sand.
  • a layer of bulk material can also consist, for example, of waste flour, as is the case with the treatment of household waste, or of sieve residues, as is the case with the treatment of household waste.
  • waste treatment products are used as bulk material, it may be expedient to provide a separating layer between the substrate layer and the adjacent bulk material layer in order to prevent the ingress of pollutants, which are contained in the waste treatment products, from the bulk material layer into the substrate layer prevent.
  • the release layer is then preferably - a made of pressed mineral wool - rock fiber layer on one side with a porous glass fiber fleece and a porous Pol mervlies y on the basis of core / sheath fibers laminated with a porous glass fiber fleece or both sides, namely adjacent to the substrate layer Side surface with the glass fiber fleece and optionally the side surface with the polymer fleece bordering on the bulk material layer, wherein the glass fiber fleece preferably let Apel fibers of randomly arranged G and a binder based on a melamine-formaldehyde resin, wherein the proportion of the binder to the glass fiber fleece 12 - 18%, a basis weight of 50 - 100 g / m 2 and a porosity of 1000 - 3000 1 / m I / sec.
  • the polymer fleece is preferably based on randomly arranged core / sheath fibers, the core of which is made of polypropylene and the sheath of which is polyethylene, the weight ratio of polypropylene to polyethylene being 70:30, a weight per unit area of 280 g / m 2 and has a water permeability of 30 1 / m 2 / sec. (10 cm WS).
  • the separating layer is preferably in the form of a sack, and is a glass fiber layer consisting of pressed glass wool, which is coated on one side with a porous polymer fleece
  • the polymer nonwoven is preferably based on randomly arranged core / sheath fibers, the core of which is made of polypropylene and the sheath of which is made of polyethylene, the weight ratio of propylene to polyethylene being 70:30, a weight per unit area of 280 g / m 2 and one Water permeability of 30 1 / m 2 / sec.
  • the glass fiber fleece preferably consists of randomly arranged glass staple fibers and a binder based on a Melamine-formaldehyde resin, the proportion of the binder in the glass fiber fleece is 12-18%, has a weight per unit area of 50-100 g / m 2 and a porosity of 1000-3000 1 / m 2 / sec. according to DIN 53857.
  • the lamination is carried out on conventional lamination devices in a manner known per se.
  • the polymer fleece is laminated on, for example, using an adhesive based on an acrylate dispersion modified with a rosin ester resin.
  • the glass fiber fleece is laminated on, for example, using an adhesive based on a phenol-formaldehyde resin. An approximately 20% aqueous phenol-formaldehyde resin solution has proven to be suitable.
  • the polymer fleece has a particularly high tear strength and has a low porosity, which ensures that practically no pollutants get from the bulk material layer into the substrate layer.
  • living plant stems can be provided, which give the structure further stability with their roots.
  • further living plant stems are also provided in pairs in the substrate layer, between which wires are tensioned for anchoring the structure.
  • the living plant stems can also be replaced by plastic rods covered with plastic.
  • a concrete wall can also be provided. Fastening hooks are then provided on the concrete wall at the same height as the living plant trunks or metal rods located on both sides, between which wires are tensioned for anchoring the structure.
  • living plant trunks or plastic rods covered with plastic are also provided in the substrate layer, to which the wire mesh is anchored with the aid of wires.
  • the living plant stems and / or metal rods provided for anchoring the structure and the living plant stems and / or metal rods provided for anchoring the wire mesh can of course also be the same.
  • the wire mesh is convexly curved several times in the horizontal and several times in the vertical direction. At the intersection of the convex curvatures, the wire mesh is connected to the plant trunks or metal rods via wires.
  • the shape of a sack closes in the event that the separating layer between the substrate layer and the bulk material layer has and the bulk material consists of sieve residues, as they arise in the treatment of household waste, the sack directly on the (outer) stone fiber layer at the level of the cut surfaces of the curvatures of the wire mesh or the stone fiber layer.
  • a layer of a loose fill of blast furnace slag, burning peat or lignite can be provided between the wire mesh and the stone fiber layer as a further layer.
  • the shoots of the bedding-resistant plants then grow through the gaps in the loosely heaped layer and cover the structure with a particularly dense plant covering.
  • the structure according to the invention represents a living unit and can be addressed as a veritable eco-system that can be maintained practically indefinitely. It is noteworthy that the new structure is viable without any artificial irrigation.
  • the lower stone fiber mat can also remain uncovered and can be provided with a water-repellent and washable impregnation, for example a silicone impregnation.
