Definitions

  • the present invention involves a design of a sound barrier of the type comprising upright supports or pillars configured for anchoring in the ground, while between said supports or pillars are fastened elongated and primarily horizontally extending shield elements consisting of one or more layers of sheets and one or more layers of sound-absorbing granule material.
  • the sound-absorbing granules are based on recycled glass fiber.
  • the invention likewise concerns a method of producing a sound barrier.
  • the purpose of the invention is to indicate a new type of soundproofing material and a design for an improved sound barrier, primarily intended for mounting along railroad tracks or highways with high traffic density etc., served by high-speed trains - such as electrically powered high-speed trains or motor vehicles in the case of highways.
  • a further purpose of the invention is to utilize granules based on recycled glass fiber, where the glass fiber has previously been used in wind turbine blades, sailboats, and other non-polluting components.
  • the fiberglass granules which are used are mechanically crushed into pieces varying in length and thickness, and therefore the granules which are used are not homogeneous in size.
  • Utilization of the indicated granules can help alleviate the major environmental storage problems affecting the wind turbine industry, among others, in connection with the stockpiling of used wind turbine blades, as well as waste products and scraps from new production of wind turbine blades, for example.
  • a further purpose of the invention is to make a sound barrier which is not destroyed by either wind, water, or temperature changes, including frost, such that the elements of the sound barrier are resistant to the climate in which the sound barrier is installed.
  • a purpose of the invention is to utilize the raw granules in loose form, where the granules are not further processed in any way or processed for any purpose other than pure granules.
  • Design of sound barriers of the type comprising upright supports or pillars configured for anchoring in the ground, while between said supports or pillars are fastened elongated and primarily horizontally extending shield elements consisting of one or more layers of sheets and one or more layers of sound-absorbing granule material.
  • the sound-absorbing granules are based on recycled glass fiber.
  • the sound barrier is special in that the shield elements are designed as assembled cassette structures and outfitted with means for blowing in of granules or the granules are packed in sack means that are directly placed in the shielding elements, wherein the granules are hygroscopic and packed in a sack material made of a water-soluble film.
  • the granules are preferably used loose.
  • the high density thus allows one to produce "slender sound barrier cassettes" due to the high weight per unit area.
  • the fiberglass granules by virtue of their loose form can thus be directly shoveled, poured, blown, inflated, guided, led, or otherwise introduced directly into the soundproofing cassette, e.g., by conveyor belt, with the help of screw conveyors, or otherwise.
  • the granules is blown into the cassettes.
  • the fiberglass granules can be introduced for example in sack means, where the sack means are made of a water-soluble film material.
  • the sack can furthermore be directly positioned in the shielding element or the shielding element can be afterwards placed in a sack filled in this way. There are further possibilities for lining the sack.
  • the granules will be supplied to a type of tube, such as a round tube or a rectangular tube, and preferably connected to funnel for supply of granules at one end of the tube, and where the other end of the tube has a connection to sacks for filling with said granules.
  • a type of tube such as a round tube or a rectangular tube
  • the sack or membrane can be endless for example in the form of tubes or hoses, making it possible for one end to be closed, gathered, or in some other way halt the passage of granules, which are possibilities, not necessities, as desired and required for the handling, packing and filling of granules in cassettes. Depending on the surroundings, one possibility can thus be to place a filled sack or membrane with granule material at the application site for the sound barrier.
  • the granules are loose and can be subjected to water also means that the granules are broken up by frost and thus become even more pieces, which simply means a fine dividing of the material, not having as such any functional importance to the soundproofing effect of the granules.
  • the sack material is soluble in water, so that the granules can be placed in the cassette as a whole, after which the sack is dissolved and the granules then obtain a surface which enables a larger contact surface in regard to uptake of water and thus an increasing of what the skilled person understands as being weight per unit area.
  • water-soluble films examples are known from PVOH, PVA, and PVAL.
  • water-soluble films are used in many compounds - including as a "form releaser" - since epoxy does not adhere to polyvinyl alcohol.
  • the combination of the granules being hydroscopic and thus taking up water and the sack likewise dissolving on account of the permeable fiber membrane means that the fibers will remain in the sack under dry conditions.
  • the sound barrier cassette When the sound barrier is set up, the sound barrier cassette will be subjected to the weather conditions and the sack will be dissolved.
  • the binder in the crushed fiberglass granules is typically epoxy, so that the water-soluble film thus will not bind to it. Films which are not water-soluble will be perforated to allow for absorption.
  • the use of the water-soluble film only finds exclusive application as a filler packaging during the production process of the cassette, so that noise pollution etc. is avoided.
  • the packaging will be intact during transport and thus also act as a sound barrier during transport. Thus, it will not be possible for any noise pollution to occur during the production process or in a logistical connection, when the sound barrier cassettes are being handled in closed premises or rooms.
  • One or more sheets are reflective and/or one or more sheets are corrugated.
  • perforations in one or more sheets which perforations are not larger than those which are able to hold back the granules.
  • the design of the sound barrier is of the type comprising upright supports or pillars, which can be anchored in the ground, wherein there are secured between said supports or pillars elongated primarily horizontally extending shield elements, consisting for example of thin-wall profiled metal sheets and a core of a sound-absorbing granule material, characterized in that granules are used which are based on recycled glass fiber.
  • the sound barrier is distinguished in being designed such that granules can be blown into an assembled cassette structure.
  • the cassette which is designed to be filled with granules is characterized in being able to be provided with an internal stiffening.
  • it can be an internal stiffening. In this way, one achieves further shape stability and strength.
  • there can be an external stiffening instead of an internal one, or as a supplement to an internal stiffening.
  • the sound barrier is characterized in that the absorption is different and varies as a consequence of the fiber size blown in.
  • the sound barrier is characterized in that the granules have no further processing or crushing.
  • the glass fibers have thus been used previously for another purpose, but can now be used for an entirely different purpose instead of being taken to a dump site.
  • the glass fiber can thus typically be a waste material or a waste product made into granules with no further processing. That is, the granules as the starting product do not have to be supplied with liquids, undergo heat treatment or the like, in order to be used for the mentioned purpose.
  • the sound barrier is characterized in that the granules are hygroscopic and thus take up water.
  • the hygroscopic property will contribute to an increased density and thus an increased soundproofing.
  • the sound barrier is characterized in being designed so that it can be mounted in a way such that the granules are blown in after the mounting.
  • the cassettes are configured such that they can be connected and have one or more channels, so that the granules can be blown in after mounting. The blowing or other filling method can occur after the cassette has been mounted in pillars on-site.
  • the cassette can furthermore be designed with a removable sheet or an opening, so that the granules can be filled into the cassettes.
  • a removable sheet or an opening is placed so that the removal and the refilling of the granules can be done with the cassette mounted in pillars on-site.
  • the sound barrier design according to the invention is characterized in that the sound barrier is designed such that granule fill can be blown into the wall of the shield.
  • the sound barrier thus becomes absorbing from both sides facing the noise source - such as a railway or highway.
  • the sound barrier cassette is based on a self-supporting structure with internal stiffening - such that the granules etc. only act as absorbing and soundproofing material - characterized by its high density and good absorbing properties.
  • noise can be absorbed by means of the fill which is blown into the shield, thereby achieving an extremely effective absorption of the sound pressure waves from, e.g., passing high-speed trains or a motor vehicle or some other noise source, in that the sound pressure waves are effectively absorbed in the granules.
  • the absorption in the sound barrier as a whole is thereby increased very significantly.
  • the sound barrier design according to the invention is such that the cassette can be produced in various self-supporting configurations.
  • a cassette consists of a top and a bottom, as well as side pieces, all of which are connected to form an assembled frame.
  • the frame is provided with a net or a perforated sheet. Behind the net or the perforated sheet is mounted a fiber membrane, which allows for the passage of air. If the granules are already filled into a sack or a net of corresponding material and/or with corresponding function, the providing of a net or a perforated sheet for the frame can be omitted.
  • the permeable fiber membrane allows for passage of the blowing air and at the same time acts as a filter, so that the granules are held back by the fiber membranes.
  • the internal configuration of the shield will have many different designs in order to achieve sufficient stability.
  • the sound barrier shown in Fig. 1-4 is built as a self-supporting structure.
  • the cassette is mounted in or on pillars, such as those with an H-profile, which are anchored in the ground, and between which the cassettes are mounted primarily horizontally as running shielding elements.
  • the cassette for example consists of thin-wall profiled metal sheets 4 and a filled core 9 of a sound-absorbing granule material.
  • the sound barrier 10 as shown can also comprise various profile sheets and corrugated trapezoidal sheets, which form a mechanical barrier and front side of the shield 10. What is common to all the sheets which are mounted on the front is that they are perforated to one degree and extent or another.
  • the shield consists of a top profile 1, a bottom profile 2 and side pieces 6, which are joined into a shape-stable and self-supporting frame.
  • the internal stiffening 8 ensures that the cassette remains stable.
  • a mechanical net 4 is mounted in order to hold back the granules 9.
  • Behind this net is mounted a permeable fiber membrane 3. The fiber membrane allows the passage of the blowing-in air, but at the same time holds back the blown-in granules.
  • Figure 2 shows an empty cassette with a sheet, here a side piece 6 and top profile with a hole 7 for blowing in of granules.
  • the cassette is designed for serial connection to identical cassettes.
  • Figures 3 and 4 show a cassette or a shield element 10 which is placed on a base 12 such as the ground and with connection means for a hose 11 for blowing in of granules in the form of recycled glass fiber.
  • Figure 5 shows a cassette 10 which is designed to receive granules.
  • the cassette 10 shown can receive one or more sound-reflecting sheets and at the same time receive granules, see the previous figures.
