Description
Granulatfyldt absorberende støjskærm Frembringelsens områdeGranule-filled absorbent noise screen Area of production
Den foreliggende frembringelse angår en indretning ved støjskærm af den type, der omfatter lodrette støtter eller stolper udformet til forankring i jorden og hvor der mellem nævnte støtter eller stolper er fastgjort aflange i hovedsagen vandret forløbende skærmelementer bestående af et eller flere lag af plader samt et eller flere lag af lydabsorberende granulat materiale.The present invention relates to a noise shield device of the type comprising vertical supports or posts formed for anchoring in the ground and wherein elongated generally extending horizontally extending screen elements consisting of one or more layers of plates and one or more layers are fixed between said supports or posts. several layers of sound-absorbing granular material.
Frembringelsen angår ligeledes en metode til etablering af en støjskærm. Frembringelsens baggrundThe production also relates to a method for establishing a noise shield. The background of the creation
Ved opstilling af støjskærm langs med eksempelvis jernbaner, som er betjent af højhastighedstog kan det ofte være problematisk at opnå den ønskede og påkrævende støjdæmpning og absorption.When setting up noise screens along, for example, railways operated by high-speed trains, it can often be problematic to achieve the desired and required noise reduction and absorption.
Fra DK 177352 Bl er en støjskærm kendt, hvor der i støjskærmen anvendes granulat af eksempelvis fiberglas, hvor granulatet bindes sammen ved hjælp af en klæber til en sammenhængende måtte, der er dækket med en vanduigennemtrængelig membran. Den nævnte støjskærm er således ikke modstandsdygtig overfor vand, idet vand ødelægger den sammenhængende klæbeeffekt, hvor tilførslen af vand yderligere vil kunne forårsage frostsprængninger og hvor støjskærmen hermed dels vil blive ødelagt og dels vil den støjskærmende effekt mindskes.From DK 177352 B1 a noise shield is known, where granules of, for example, fiberglass are used, in which the granules are bonded together by means of an adhesive to a continuous mat covered with a water-impermeable membrane. The said noise shield is thus not resistant to water, as water destroys the cohesive adhesive effect, where the supply of water can further cause frostbite and whereby the noise shield will thereby partly be destroyed and partly the noise shielding effect will be reduced.
Frembringelsens baggrund På den baggrund er det formålet med frembringelsen at angive en ny type støjdæmpning smateriale og indretning ved en forbedret støjskærm, der primært er udviklet til montering langs med jernbanetrækninger eller motorveje med høj trafiktæthed etc., der betjenes af højhastighedstog - eksempelvis elektrisk drevne højhastighedstog henholdsvis motordrevne automobiler for vejenes vedkomne.Background of production On this basis, the purpose of the generation is to specify a new type of noise reduction material and device for an improved noise shield, which is primarily designed for mounting along railways or high-traffic highways, etc., operated by high-speed trains - for example, electric high-speed trains motor vehicles for the roads, respectively.
Det er yderligere et formål med frembringelsen, at der benyttes granulat baseret på genanvendt glasfiber, hvor glasfiberen tidligere har været anvendt i vindmølle vinger, sejlbåde og andre ikke forurenende komponenter.It is a further object of the invention to use granules based on recycled fiberglass, where the fiberglass has previously been used in wind turbine blades, sailboats and other non-polluting components.
Glasfibergranulatet, der anvendes, er mekanisk neddelt til stykker, der varierer i længde og tykkelse, og det anvendte granulat er derfor ikke homogent i størrelse.The fiberglass granules used are mechanically subdivided into pieces that vary in length and thickness, and therefore the granules used are not homogeneous in size.
Anvendelse af det pågældende granulat vil kunne medvirke til afhjælpning af de store miljømæssige opmagasineringsproblemer, som blandt andet vindmøllebranchen er berørte af, i forbindelse med deponi af udtjente vindmøllevinger, samt spildvarer og rester fra ny produktion af eksempelvis vindmøllevinger.The use of the granules in question could help to alleviate the major environmental storage problems that, among other things, the wind turbine industry is concerned with in the landfill of waste wind turbines, as well as waste products and residues from new production of, for example, wind turbine blades.
Det er yderligere et formål med frembringelsen at lave en støjskærm, der ikke bliver ødelagt af hverken vind, vand eller temperatursvingninger herunder frost, og således at støjskærmens elementer er modstandsdygtige overfor det klima støjskærmene opsættes i.It is a further object of the invention to make a noise shield which is not destroyed by neither wind, water nor temperature fluctuations including frost, and so that the noise shield elements are resistant to the climate noise screens are set up in.
Endelig er det formålet med frembringelsen at anvende den rå granulat i løs form, hvor granulaten ikke er efterbehandlet på nogen måde eller behandlet til noget andet end blot granulat.Finally, the purpose of the preparation is to use the raw granules in loose form, where the granules are not processed in any way or treated for anything other than mere granules.
Beskrivelse af frembringelsenDescription of the production
Indretning ved støjskærm af den type, der omfatter lodrette støtter eller stolper udformet til forankring i jorden, og hvor der mellem nævnte støtter eller stolper er fastgjort aflange i hovedsagen vandret forløbende skærmelementer bestående af et eller flere lag plader samt et eller flere lag af lydabsorberende granulatmateriale. Det lydabsorberende granulat er baseret på genanvendt glasfiber, hvor granulatet fortrinsvist anvendes løst. Den høje rumvægt tillader således at fremstille ’’slanke støjskærmskassetter” på grund af den høje overfladevægt.Device by noise shield of the type comprising vertical supports or posts designed for anchoring in the ground, and wherein said support or posts are fixed to elongated generally extending screen elements consisting of one or more layers of plates and one or more layers of sound-absorbing granular material . The sound-absorbing granule is based on recycled fiberglass, where the granule is preferably used loosely. The high room weight thus allows to produce '' slender noise screen cartridges '' due to the high surface weight.
Glasfibergranulatet kan således i kraft af sin løse form direkte skovles, hældes, blæses, pustes, føres, ledes eller på anden vis, f.eks. på transportbånd, ved hjælp af snegleføringer eller andet indføres direkte i et skærmelements kassette.Thus, by virtue of its loose form, the fiberglass granule can be directly shoveled, poured, blown, breathed, guided, guided or otherwise, e.g. on conveyor belts, by means of auger guides or otherwise inserted directly into the screen of a screen element.
Alternativt kan glasfibergranulatet indføres i eksempelvis en pose eller et net, hvor posen eller nettet kan være af plast, polymer, gummi eller et hvilket som helst andet ønsket og anvendeligt materiale. Et posemateriale kan for eksempel være lavet af en membran og enten være væskeuigennemtrængeligt eller væskegennemtrængeligt og således permeabelt, hvor eksempelvis perforeringer tillader vand, luft og lyd at passere. Et net kan for eksempel være fleksibelt fremstillet ved ekstrudering.Alternatively, the fiberglass granule may be introduced into, for example, a bag or net, where the bag or net may be of plastic, polymer, rubber or any other desired and useful material. For example, a bag material may be made of a membrane and be either liquid impermeable or liquid permeable and thus permeable where, for example, perforations allow water, air and sound to pass. For example, a mesh may be flexibly manufactured by extrusion.
Posen eller nettet kan desuden være direkte positioneret i skærmelementet eller skærmelementet kan efterfølgende isættes eller ilægges en sådan fyldt pose eller net. Der er yderligere muligheder for foring af posen eller nettet.In addition, the bag or net may be directly positioned in the screen member or the screen member may subsequently be inserted or loaded into such a filled bag or net. There are additional options for lining the bag or net.
Rent praktisk vil granulatet blive tilført en form for rør, eksempelvis et rundt rør eller et firkantrør og fortrinsvist forbundet til en tragt for tilførsel af granulat i den ene ende af røret, og hvor der i rørets anden ende er forbindelse til poser eller net til fyldning med nævnte granulat.In practical terms, the granulate will be fed into a form of tube, for example a round tube or square tube, and preferably connected to a funnel for supplying granules at one end of the tube and where at the other end of the tube is connected to bags or nets for filling. with said granules.
Pose eller membran kan være endeløse i form af eksempelvis rør eller strømper, der muliggør, at en ende kan lukkes, samles eller på anden vis stoppe gennemløb af granulat, hvilket efter ønske og behov for håndteringen, pakningen og fyldningen af granulat i kassetter er muligheder, ikke nødvendigheder. Af hensyn til omgivelserne kan det således være en mulighed at isætte en fyldt pose eller membran med granulatmateriale på anvendelsesstedet for støjskærmen.The bag or diaphragm may be endless in the form of, for example, tubes or stockings that allow an end to be closed, assembled or otherwise stop the passage of granules, which as desired and need for handling, packing and filling of granules in cartridges are possible , not necessities. Thus, for the sake of the environment, it may be possible to insert a filled bag or membrane with granular material at the point of application of the noise shield.
Det at granulatet er løst og gerne må udsættes for vand, kan også medføre, at granulatet frostsprænger og således bliver til endnu flere stykker, hvilket blot betyder en findeling af materialet, hvilket ikke som sådan har nogen funktionel betydning for granulatets lydisolerende effekt. I yderligere alternative udførselsformer kan posematerialet ligeledes være opløseligt i vand, således at granulatet kan placeres i kassetten som en enhed, hvorefter posen opløses og granulatet dernæst får en overflade, der muliggør en større kontaktoverfla-de med henblik på optagelse af vand og således en forøgelse af det, som en fagmand vil forstå som værende o verflade vægten.The fact that the granulate is dissolved and may be exposed to water can also cause the granulate to freeze and thus become even more pieces, which simply means a comminution of the material, which as such has no functional significance for the sound insulating effect of the granulate. In further alternative embodiments, the bag material may also be soluble in water, so that the granulate may be placed in the cassette as a unit, after which the bag is dissolved and the granulate then provided with a surface which allows a larger contact surface for water uptake and thus an increase. of what a person skilled in the art will understand as being obliterated.
Eksempler på vandopløselige folier kendes fra PVOH, PVA, og PVAL.Examples of water-soluble films are known from PVOH, PVA, and PVAL.
Anvendelse af vandopløselige folier benyttes i mange forbindelser - blandt andet som “form releaser” - dersom epoxy ikke klæber til Polyvinyl alcohol. Kombinationen med at granulatet er hygroskopisk og dermed vandsugende og posen ligeledes opløses udefra på grund af den permeable fibermembran betyder, at fibrene under tørre forhold vil forblive i posen. Når støjskærmen sættes op vil støjskærmskassetten blive udsat for vejrlige forhold og posen vil blive opløst. Bindemidlet i det neddelte glasfibergranulat er typisk epoxy, hvorfor den vandopløselige folie således ikke vil binde sig til denne. Folier der ikke er vandopløselig skal perforeres for at tillade absorption. Absorption ved en granulatopfyldt vandopløselig folie opstår, når folien kommer i kontakt med fugtighed og vand. Der er således ingen grund til at anvende perforeret folie, når der anvendes vandopløselige folier. Anvendelse af vandopløselige folier er kendt i forbindelse med andre elementer, men er aldrig anvendt i forbindelse med hygroskopisk glasfibergranulat i forbindelse med en støjskærm.The use of water-soluble films is used in many compounds - including as "form releases" - if epoxy does not adhere to Polyvinyl alcohol. The combination of the granulate being hygroscopic and thus water-sucking and the bag also dissolving from the outside due to the permeable fiber membrane means that the fibers will remain in the bag under dry conditions. When the noise shield is set up, the noise shield cassette will be exposed to weather conditions and the bag will dissolve. The binder in the broken glass fiber granulate is typically epoxy, so the water-soluble film will not bind to it. Non-water-soluble films must be perforated to allow absorption. Absorption by a granular filled water-soluble film occurs when the film comes in contact with moisture and water. Thus, there is no need to use perforated foil when using water-soluble foils. The use of water-soluble films is known in connection with other elements, but has never been used in connection with hygroscopic fiberglass granules in connection with a noise shield.
Anvendelsen af den vandopløselige folie, finder udelukkende kun anvendelse som en fyldningsemballage under fremstillingsproceduren af kassetten, således at støvgener etc. undgås. Emballagen vil være intakt under transport og dermed også virke som en støvbarriere under transport. Der vil således ikke kunne opstå støvgener under fremstilling sproceduren samt i logistik sammenhæng, hvor støjskærmskassetterne håndteres i lukkede lokaler eller rum.The use of the water-soluble film is only used as a filling package during the manufacturing process of the cassette, so that dust nuisance etc. is avoided. The packaging will be intact during transport and thus also act as a dust barrier during transport. Thus, no dust nuisance can occur during the fabrication procedure as well as in the logistics context where the noise shield cassettes are handled in closed rooms or rooms.
En eller flere plader er reflekterende og/eller en eller flere plader er korrugerede.One or more sheets are reflective and / or one or more sheets are corrugated.
Der kan være perforeringer i en eller flere plader, hvilke perforeringer ikke er større end, at de er i stand til at tilbageholde granulatet. I en speciel udførelse er indretningen ved støjskærm af den type, der omfatter lodrette støtter eller stolper, som kan forankres i jorden, hvor der mellem nævnte støtter eller stolper er fastgjort aflange i hovedsagen vandret forløbende skærmelementer, der eksempelvis består af tyndvæggede profilerede metalplader samt en kerne af et lydabsorberende granulat materiale, som er ny ved, at der benyttes granulat som er base- ret på genanvendt glasfiber. Ydermere er støjskærmen speciel ved at være udformet til, at der kan indblæses granulat i en samlet kassettekonstruktion.There may be perforations in one or more plates, which perforations are no greater than being able to retain the granulate. In a particular embodiment, the device by noise shield is of the type comprising vertical supports or posts which can be anchored to the ground, whereby said support or posts are fixed elongated, generally horizontally extending screen elements, for example consisting of thin-walled profiled metal plates and a core of a sound-absorbing granular material which is new in that granules based on recycled fiberglass are used. Furthermore, the noise shield is special in that it is designed to allow granules to be injected into a total cassette structure.
Dermed opnås, at granulatet ikke skal limes eller på anden måde forarbejdes inden indblæsningen. I en udførelse er kassetten, som er udformet til at fyldes op med granulat, speciel ved at være udformet til at kunne tilføjes intern afstivning. Alternativt kan der være en intern afstivning. Dermed opnås yderligere formstabilitet og styrke. I en yderligere alternativ udførselsform kan der være en ekstern afstivning i stedet for en intern eller som et supplement til en intern afstivning. I en udførelse er støjskærmen speciel ved, at absorptionen er forskellig og varieres som følge af den indblæste fiberstørrelse. I en udførelse er støjskærmen speciel ved, at granulatet er uden yderligere forarbejdning eller nedbrydning. Fortrinsvis har glasfiberen altså tidligere været anvendt til andre formål, men kan nu anvendes til noget ganske andet, i stedet for blot at blive deponeret. Glasfiberen som således typisk er et affaldsmateriale eller et affaldsprodukt laves til granulat uden nogen yderligere forædling. Det vil sige, at granulatet ikke som udgangspunkt behøves at få tilført væsker, gennemgå en varmebehandling eller tilsvarende for at kunne anvendes til det nævnte formål. I en udførelse er støjskærmen speciel ved, at granulatet er hygroskopisk og således vandsugende. Den hygroskopiske egenskab vil bidrage til en øget vægtfylde og dermed en øget støjdæmpning. I en udførelse er støjskærmen speciel ved at være udformet til at kunne monteres således, at granulatet indblæses efter monteringen. I en speciel konfiguration er kassetterne udformet således, at de kan forbindes og har en eller flere kanaler, således at granulatet kan indblæses efter montering. Indblæsningen eller anden fyldningsmetode kan ske efter at kassetten er monteret i stolper on-site.This ensures that the granulate must not be glued or otherwise processed before the blow-in. In one embodiment, the cartridge, which is designed to be filled with granules, is specially designed to be capable of being added to internal stiffening. Alternatively, there may be an internal bracing. This provides further shape stability and strength. In a further alternative embodiment, there may be an external bracing instead of an internal bracing or as a supplement to an internal bracing. In one embodiment, the noise shield is special in that the absorption is different and varied as a result of the blown fiber size. In one embodiment, the noise shield is special in that the granulate is without further processing or degradation. Thus, the fiberglass has previously been used for other purposes, but can now be used for something quite different, instead of just being deposited. The glass fiber, which is thus typically a waste material or waste product, is made into granules without any further processing. That is, as a starting point, the granules do not need to be supplied with liquids, undergo a heat treatment or the like in order to be used for the said purpose. In one embodiment, the noise shield is special in that the granulate is hygroscopic and thus water-sucking. The hygroscopic property will contribute to increased density and thus an increased noise reduction. In one embodiment, the noise shield is special in being designed to be mounted so that the granulate is blown in after mounting. In a particular configuration, the cartridges are designed so that they can be connected and have one or more channels so that the granules can be blown in after mounting. The blow-in or other filling method can be done after the cassette is mounted in posts on-site.
Kassetten kan ydermere være udformet med en aftagelig plade eller en åbning, således at granulatet kan genfyldes i kassetterne. En sådan plade eller en sådan åbning er pla ceret således, at fjernelsen af og genfyldningen af granulatet kan ske med kassetten monteret i stolper on-site.The cassette may further be formed with a removable plate or opening so that the granules can be refilled into the cassettes. Such a plate or opening is positioned such that the removal and refilling of the granulate can be effected with the cassette mounted in posts on-site.
Indretningen ved støjskærmen ifølge frembringelsen er speciel ved, at støjskærmen er indrettet således, at der kan indblæses granulatfyld ind i skærmvæggen. Støjvæggen bliver således absorberende fra begge sider, der vender imod støjkilden - eksempelvis jernbanen eller motorvejen. Støjskærmskassetten er baseret på en selvbærende konstruktion med intern afstivning - således at granulatet etc. kun virker som absorberende og lydisolerende materiale - som er ny ved sin høje rumvægt og gode absorberende egenskaber. På den måde vil støj kunne absorberes ved hjælp af det opfyld, der er blæst ind i skærmen og herved opnås en yderst effektiv absorption af lydtrykbølgerne fra eksempelvis et passerende højhastighedstog eller et motordrevet køretøj eller andre støjkilder, idet tryklydbølgeme effektivt absorberes i granulatet. Absorptionen i støjskærmen som en enhed forøges dermed meget betydeligt.The device at the noise shield according to the invention is special in that the noise shield is arranged so that granular fill can be blown into the screen wall. The noise wall thus becomes absorbent from both sides facing the noise source - for example the railway or the highway. The noise shield cassette is based on a self-supporting structure with internal stiffening - so that the granules etc. only act as absorbent and sound insulating material - which is new due to its high room weight and good absorbent properties. In this way, noise can be absorbed by the filling blown into the screen, thereby obtaining a highly efficient absorption of the sound pressure waves from, for example, a passing high-speed train or a motor vehicle or other noise sources, the pressure sound waves being effectively absorbed in the granulate. The absorption in the noise screen as a unit is thus greatly increased.
Fortrinsvis er indretningen ved støjskærmen ifølge frembringelsen udformet således, at kassetten kan fremstilles i forskellige selvbærende udformninger.Preferably, the device at the noise shield according to the invention is designed so that the cassette can be manufactured in various self-supporting designs.
En kassette består af en top og en bund samt sidestykker, som alle forbindes til en samlet ramme.A cassette consists of a top and a bottom as well as side pieces, all of which are connected to a single frame.
Rammen forsynes med et net eller en perforeret plade. Bag nettet eller den perforerede plade monteres en fibermembran, som tillader passage af luft. Er granulatet allerede fyldt i en pose eller et net af tilsvarende materiale og/eller med tilsvarende funktion kan forsyningen af rammen med et net eller en perforeret plade undlades. I endestykkerne er der fremstillet et indblæsningshul, således at granulatet kan indblæses fra hver ende eventuelt for efterfyldning.The frame is provided with a net or a perforated plate. Behind the mesh or perforated plate is mounted a fiber diaphragm which allows air passage. If the granulate is already filled in a bag or net of similar material and / or with similar function, the supply of the frame with a net or perforated plate may be omitted. In the end pieces an injection hole is made so that the granulate can be blown in from each end possibly for backfilling.
Herved opnås en god opfyldning. Den permeable fibermembran tillader passage af indblæsningsluften og virker samtidig som et filter, således at granulatet tilbageholdes af fibermembranen.This results in a good filling. The permeable fiber membrane permits passage of the supply air and at the same time acts as a filter, so that the granulate is retained by the fiber membrane.
Afhængig af skærmens længde vil den interne udformning af skærmen udformes på mange måder for at opnå tilstrækkelig stabilitet. T egningsbeskri velseDepending on the length of the screen, the internal design of the screen will be designed in many ways to achieve sufficient stability. Character description

Detaljeret beskrivelse af frembringelsenDetailed description of the production
Den i fig. 1-4 viste støjskærm er opbygget som en selvbærende konstruktion. Kassetten monteres i eller på stolper, eksempelvis med H-profil, der er forankret i jorden, og hvorimellem kassetterne er monteret i hovedsagen vandret som forløbende skærmelementer. Kassetten består af eksempelvis tyndvæggede 4, profilerede metalplader samt en opfyldt kerne 9 af et lydabsorberende granulat materiale. Støjskærmen 10 kan som vist også omfatte forskellige profilplader og korrugerede trapez-plader, som danner en mekanisk barriere og forside på skærmen 10. Fælles for alle pladerne der monteres på fronten er, at de er perforerede i en eller anden grad og udstrækning. Det vil være yderst enkelt at sørge for potentialudligning af alle metaldele i en støjskærm af den beskrevne type, således at den også bliver velegnet til brug langs med jernbaner med elektrisk drevne tog. Skærmen består af et topprofil 1, et bundprofil 2 samt sidestyk- ker 6, der sammenføjes til en form stabil og selvbærende ramme. Den interne afstivning 8 sikrer, at kassetten forbliver stabil. For at holde på granulatet 9, monteres der et mekanisk net 4. Bag dette net monteres der en permeabel fibermembran 3. Fibermembranen tillader passage af indblæsningsluften, men holder samtidig det indblæste granulat tilbage.The FIG. 1-4 noise shield is constructed as a self-supporting structure. The cassette is mounted in or on posts, for example with an H-profile, which is anchored in the ground, and between which the cassettes are mounted essentially horizontally as protruding screen elements. The cassette consists of, for example, thin-walled 4, profiled metal sheets and a filled core 9 of a sound-absorbing granular material. As shown, the noise shield 10 may also comprise various profile plates and corrugated trapezoidal plates which form a mechanical barrier and front face of the screen 10. Common to all the panels mounted on the front is that they are perforated to some extent and extent. It will be extremely easy to provide potential equalization of all metal parts in a noise shield of the type described so that it will also be suitable for use along railways with electrically powered trains. The screen consists of a top profile 1, a bottom profile 2 and side pieces 6, which are joined together to form a stable and self-supporting frame. The internal stiffener 8 ensures that the cassette remains stable. To hold the granulate 9, a mechanical mesh 4 is mounted. Behind this mesh is mounted a permeable fiber membrane 3. The fiber membrane allows passage of the supply air, but at the same time retains the injected granulate.
Figur 2 viser jf. figur 1 en tom kassette med en plade, her et sidestykke 6 en topprofil med et hul 7 til indblæsning af granulat. Kassetten er udformet til seriekobling med identiske kassetter.Figure 2 shows, cf. Figure 1, an empty cassette with a plate, here a side section 6 a top profile with a hole 7 for blowing granules. The cartridge is designed for serial coupling with identical cartridges.
Figur 3 og 4 viser en kassette eller et skærmelement 10, der er placeret på et underlag 12 såsom jorden og med forbindelsesmidler til en slange 11 til indblæsning af granulat i form af genanvendt glasfiber.Figures 3 and 4 show a cassette or screen element 10 located on a substrate 12 such as the ground and with connecting means to a hose 11 for blowing granular in the form of recycled fiberglass.
Figur 5 viser en kassette 10, der er udformet til at modtage et granulat. Den viste kassette 10 kan modtage en eller flere lydreflekterende plader og samtidig modtage et granulat jf. tidligere figurer.Figure 5 shows a cassette 10 designed to receive a granulate. The cassette 10 shown may receive one or more sound-reflecting plates and at the same time receive a granulate as per previous figures.
