Description
DK 202100102 U3 1 Indretning af støjskærm og etablering af en støjskærm. Frembringelsens område Den foreliggende frembringelse angår en granulatfyldt eller fiberfyldt støjskærm og fremgangsmåder til etablering af en støjskærm. Frembringelsens baggrund Ved opstilling af støjskærm langs med eksempelvis jernbaner, som er betjent af højhastighedstog kan det ofte være problematisk at opnå den ønskede og påkrævende støj- dempning og absorption.DK 202100102 U3 1 Arrangement of noise screen and establishment of a noise screen. Field of the invention The present invention relates to a granulate-filled or fiber-filled noise screen and methods for establishing a noise screen. Background of the production When setting up noise barriers along, for example, railways which are operated by high-speed trains, it can often be problematic to achieve the desired and demanding noise attenuation and absorption.
Der er tidligere fremstillet støjskærme, hvor skærmene er tildannet af plader af sammenpressede granulater af genanvendt glasfiberholdigt materiale, f.eks. i form af neddelte vindmøllevinger, hvor granulaterne holdes sammen af en lim/klæber eller lignende. En sådan konstruktion er beskrevet i DK 177352 B1. Det er også kendt fra EP 0762382 Al og US 5484970 A at fremstille støjskærme, hvor granulat i form af neddelte plastik produkter, såsom kassettebånd, er fyldt i poser og ophængt i en støjskærm konstruktion.Noise shields have previously been manufactured in which the shields are formed from sheets of compressed granules of recycled fiberglass-containing material, e.g. in the form of divided wind turbine blades, where the granules are held together by a glue / adhesive or the like. Such a construction is described in DK 177352 B1. It is also known from EP 0762382 A1 and US 5484970 A to manufacture noise screens in which granules in the form of divided plastic products, such as cassette tapes, are filled in bags and suspended in a noise screen construction.
Det benyttede granulat er baseret på ”genanvendt” glas- eller kulfiber. Hermed skal forstås at glas- eller kulfiberen har tidligere været anvendt i vindmøllevinger, sejlbåde og andre ikke forurenende komponenter, og tilvejebringer et alternativ til anvendelse af eksempelvis udtjente vindmøllevinger, hvor glas- kulfiberen indgår i nye konstruktioner, således at deponi undgås.The granules used are based on "recycled" glass or carbon fiber. By this is meant that the glass or carbon fiber has previously been used in wind turbine blades, sailboats and other non-polluting components, and provides an alternative to the use of, for example, obsolete wind turbine blades, where the glass carbon fiber is included in new constructions, so that landfill is avoided.
Glas-/kulfiberen er mekanisk neddelt til granulat i stykker, der varierer i længde og tykkelse. Det anvendte granulat er derfor ikke homogent.The glass / carbon fiber is mechanically divided into granules into pieces that vary in length and thickness. The granules used are therefore not homogeneous.
I de seneste år har været et øget fokus på genanvendelse af plastholdige materialer, som f.eks. plastikposer, plastbeholdere mv., som ellers tidligere vil blive brændt af eller deponeret på store lossepladser. Plastmaterialet kan neddeles til granulat med en relevant ensartet størrelse og genanvendes til fremstilling af nye plastprodukter. Frembringelsens formål På den baggrund er det formålet med frembringelsen at angive en ny typeIn recent years, there has been an increased focus on recycling plastic materials, such as plastic bags, plastic containers, etc., which will otherwise previously be burned off or deposited in large landfills. The plastic material can be divided into granules of a relevant uniform size and recycled for the production of new plastic products. Purpose of the production On that basis, the purpose of the production is to specify a new type
DK 202100102 U3 2 støjdæmpningsmateriale 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.DK 202100102 U3 2 noise reduction material and device for an improved noise screen, which is primarily developed for installation along railway lines or motorways with high traffic density, etc., which are operated by high-speed trains - for example electrically powered high-speed trains or motor vehicles for road use.
Beskrivelse af frembringelsen 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 et lydabsorberende granulat materiale. Som kerne benyttes et granulat, der har en størrelse og udformning, der er tilpasset til indblæsning af granulatmaterialet. Støjskærmen ifølge frembringelsen er kendetegnet ved, at skærmelementerne omfatter kassetter, der er udformet med en valgfri lem, en låge eller tilsvarende midler til tømning og/eller fyldning af kassetten.Description of the invention Device by noise shield of the type comprising vertical supports or posts designed for anchoring in the ground, and where elongate substantially horizontal screen elements consisting of one or more layers of plates and one or more layers are attached between said supports or posts. of a sound-absorbing granular material. As the core, a granulate is used which has a size and design which is adapted for blowing the granulate material. The noise screen according to the invention is characterized in that the screen elements comprise cassettes formed with an optional limb, a door or similar means for emptying and / or filling the cassette.
En eller flere plader er af reflekterende og/eller en eller flere plader er korrugerede plader. Der kan være perforeringer i en eller flere plader, hvilke perforeringer til- bageholder granulatet.One or more plates are of reflective and / or one or more plates are corrugated plates. There may be perforations in one or more plates, which perforations retain the granulate.
Fortrinsvis er indretningen ved støjskærmen ifølge frembringelsen udformet således, at kassetten kan fremstilles i forskellige selvbærende udformninger.Preferably, the device at the noise screen according to the invention is designed so that the cassette can be manufactured in different self-supporting designs.
En kassette består af en top og en bund samt sidestykker, som alle forbindes til en samlet ramme. Rammen forsynes med et net eller en perforeret plade. Bag nettet eller den perforerede plade monteres en fibermembran som tillader passage af luft. I en eller begge endestykker og/eller sidestykker er der fremstillet et indblæsningshul, således at granulatet kan indblæses fra siden, top eller bund 1 kassetten. Indblæsningshullet kan være tilpasset til størrelsen på indblæsningsudstyret.A cassette consists of a top and a bottom as well as side pieces, all of which are connected to a single frame. The frame is provided with a net or a perforated plate. Behind the net or the perforated plate is mounted a fiber membrane which allows the passage of air. A supply hole is made in one or both end pieces and / or side pieces, so that the granulate can be blown in from the side, top or bottom of the cassette. The supply hole can be adapted to the size of the supply equipment.
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, kendetegnet ved, at der benyttes granulat med en størrelse, der er tilpasset til indblæsning af granulat materialet. Ydermere er støjskærmen speciel ved at være udformet til, at granulatet kan indblæses i en samletIn a special embodiment, the device at the noise screen is of the type comprising vertical supports or posts which can be anchored in the ground, where elongate, substantially extending screen elements are fastened between said supports or posts, consisting for example of thin-walled profiled metal plates and a core of a sound-absorbing granular material, characterized in that granules with a size adapted for blowing the granular material are used. Furthermore, the noise shield is special in that it is designed so that the granulate can be blown into a combined
DK 202100102 U3 3 kassettekonstruktion. Dermed opnås, at granulatet ikke skal limes sammen eller på anden måde forarbejdes inden indblæsningen. Dette reducerer arbejdsprocessen i forbindelse med fyldning af kassetten. 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.DK 202100102 U3 3 cassette construction. This ensures that the granules do not have to be glued together or otherwise processed before the injection. This reduces the workflow associated with loading the cartridge. In one embodiment, the cassette, which is designed to be filled with granules, is special in that it is designed to be able to be added to internal bracing. Alternatively, there may be an internal brace. This achieves additional dimensional stability and strength.
I en udførelse er støjskærmen speciel ved, at absorptionen er forskellig og varieres som følge af den indblæste størrelse på granulatet. Med udtrykket ”granulat” skal der her forstås en størrelse og udformning, inkl. korn, spåner og flager, der kan indblæses ved hjælp af konventionelt indblæsningsudstyr.In one embodiment, the noise shield is special in that the absorption is different and varies due to the blown size of the granulate. By the term "granulate" is meant here a size and design, incl. grain, shavings and flakes that can be blown in using conventional blowing equipment.
I en udførelse er støjskærmen speciel ved, at granulatet, f.eks. i form af spåner eller flager, har en størrelse, så granulatet kan indblæses i kassetten uden yderligere forarbejdning eller nedbrydning. Dette er særlig fordelagtigt, da de kommercielt tilgængelige fiberholdige produkter, f.eks. vindmøllevinger, fra affaldsproducenterne ofte har en så stor størrelse, at det kræver en finere neddeling og filtrering før granulatet kan indføres i kassetten. Endvidere muliggør dette bruges af standard kommercielt tilgængeligt indblæsningsudstyr, såsom slanger og pumper. Herved elimineres behovet for specielt tilpasset indblæsningsudstyr, hvorved omkostningerne også reduceres.In one embodiment, the noise shield is special in that the granulate, e.g. in the form of shavings or flakes, have a size so that the granules can be blown into the cassette without further processing or degradation. This is particularly advantageous as the commercially available fibrous products, e.g. wind turbine blades, from the waste producers often have such a large size that it requires a finer division and filtration before the granules can be introduced into the cassette. Furthermore, this allows the use of standard commercially available supply equipment, such as hoses and pumps. This eliminates the need for specially adapted supply equipment, which also reduces costs.
I en udførelse er støjskærmen speciel ved, at granulatet er hygroskopisk og således vandsugende. Den hygroskopiske egenskab vil bidrage til en øget vægtfylde og der- med en øget støjdæmpning.In one embodiment, the noise shield is special in that the granulate is hygroscopic and thus water-absorbent. The hygroscopic property will contribute to an increased density and thus an increased noise reduction.
I en udførelse er støjskærmen speciel ved at være udformet til at kunne monteres såle- des, 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. Monteringen kan ske efter, at kassetten er monteret i H- stolper on-site.In one embodiment, the noise screen is special in that it is designed to be able to be mounted so that the granulate is blown in after mounting. In a special configuration, the cassettes are designed so that they can be connected and have one or more channels so that the granulate can be blown in after mounting. Mounting can be done after the cassette is mounted in H-posts on-site.
Kassetten kan ydermere være udformet med en lem, en låge eller en aftagelig plade ellerThe cassette can furthermore be designed with a hatch, a door or a removable plate or
DK 202100102 U3 4 en hængslet eller roterbar plade, der er arrangeret foran en åbning i kassetten, således at granulatet kan genfyldes i kassetterne. En sådan plade er placeret således, at fjernelsen af og/eller genfyldningen af granulatet kan ske med kassetten monteret i H-stolper on-site.DK 202100102 U3 4 a hinged or rotatable plate arranged in front of an opening in the cassette so that the granules can be refilled in the cassettes. Such a plate is positioned so that the removal and / or refilling of the granulate can take place with the cassette mounted in H-posts on-site.
Indretningen ved støjskærmen ifølge frembringelsen er speciel ved, at støjskærmen er indrettet således, at der kan indblæses granulatfyld ind i skærmvæggens skærmelementer. Støjvæggen bliver således absorberende på begge sider, der vender imod støjkilden - eksempelvis jernbanen eller motorvejen.The device at the noise screen according to the invention is special in that the noise screen is arranged so that granular filling can be blown into the screen elements of the screen wall. The noise wall thus becomes absorbent on both sides facing the noise source - for example the railway or the motorway.
Støjskærmselementerne/kassetten er baseret på en selvbærende konstruktion med intern afstivning — således at granulatet etc. kun virker som absorberende materiale. 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, idet tryklydbølgerne effektivt absorberes i granulatet. Absorptionen i støjskærmen som en enhed forøges meget betydeligt. Herved opnås en god opfyldning. Den permeable fibermembran tillader passage af indblæsningsluften og virker samtidig som et filter, således at granulatet tilbageholdes af fibermembranen. Der kan være arrangeret en fibermembran nær henholdsvis forsiden og bagsiden af kassetten. Afhængig af skærmens længde vil den interne udformning af skærmen udformes på mange måder for at opnå tilstrækkelig stabilitet. I en udførelse er støjskærmen speciel ved, at granulatet er fremstillet af et genanvendt materiale eller et overskudsmateriale, såsom glas-/kulfiberholdige materialer eller plastmaterialer. Fiber af andre typer kan med fordel også anvendes. Med udtrykket ”genanvendt” skal der forstås et produkt, der tidligere har været anvendt til et bestemt formål, f.eks. udtjente komposit- eller plastprodukter. Med udtrykket ”overskud” kan der forstås et materiale, der er tilbage eller tilovers efter produktionen af et andet produkt, feks. overskydende glas-/kulfiber eller plastgranulater.The noise shield elements / cassette are based on a self-supporting construction with internal bracing - so that the granulate etc. only acts as an absorbent material. In this way, noise can be absorbed by means of the filling blown into the screen and thereby a highly efficient absorption of the sound pressure waves from, for example, a passing high-speed train or a motor vehicle is obtained, the pressure sound waves being efficiently absorbed in the granulate. The absorption in the noise screen as a unit increases very significantly. This results in a good filling. The permeable fiber membrane allows the passage of the supply air and at the same time acts as a filter, so that the granulate is retained by the fiber membrane. A fibrous membrane may be arranged near the front and back of the cassette, respectively. Depending on the length of the screen, the internal design of the screen will be designed in many ways to achieve sufficient stability. In one embodiment, the noise shield is special in that the granulate is made of a recycled material or a surplus material, such as glass / carbon fiber-containing materials or plastic materials. Fiber of other types can also be used to advantage. By the term "recycled" is meant a product that has previously been used for a specific purpose, e.g. obsolete composite or plastic products. The term "surplus" can mean a material that is left over or left over after the production of another product, e.g. excess glass / carbon fiber or plastic granules.
DK 202100102 U3 Granulatet kan med fordel være fremstillet af et polymer baseret plastmateriale, f.eks. Polypropylen (PP), Polyethylen (PE), Polyamid (PA), Akrylonitril-butadien-styren (ABS), Polystyren (PS), polyoxymethylen (POM), Polykulat (PC), eller en kombination deraf. 5 I en udførelse er støjskærmen speciel ved, at granulatet er indblæst direkte i kassetten eller indblæst i en lukket afgrænset lomme formet inde i kassetten. Granulatet kan 1 den foreliggende frembringelse med fordel indblæses direkte ind i kernen af kassetten via indblæsningsåbninger i rammen, som nævnt tidligere. Granulatet kan dermed holdes mekanisk på plads mellem de to fibermembraner. Et valgfrit supplerende lag af et permeabelt fleksibelt materiale kan være arrangeret bag ved fibermembranen. Dette fleksible lag kan også være med til mekanisk at holde granulatet på plads. Alternativt kan to lag af fibermembraner anvendes.DK 202100102 U3 The granulate can advantageously be made of a polymer based plastic material, e.g. Polypropylene (PP), Polyethylene (PE), Polyamide (PA), Acrylonitrile-butadiene-styrene (ABS), Polystyrene (PS), Polyoxymethylene (POM), Polyculate (PC), or a combination thereof. In one embodiment, the noise shield is special in that the granulate is blown directly into the cassette or blown into a closed delimited pocket formed inside the cassette. In the present invention, the granulate can advantageously be blown directly into the core of the cassette via blowing openings in the frame, as mentioned earlier. The granulate can thus be held mechanically in place between the two fiber membranes. An optional supplementary layer of a permeable flexible material may be arranged behind the fibrous membrane. This flexible layer can also help to mechanically hold the granulate in place. Alternatively, two layers of fiber membranes can be used.
Kun ét fleksibelt lag kan være arrangeret i rammen, enten bag den forreste eller bagerste fibermembran. Alternativt kan der være arrangeret et fleksibelt lag bagved begge fibermembraner. Det fleksible lag kan fastgøres til fibermembranen og/eller selve rammen under samlingen af kassetten, eller være mekanisk fikseret i kassetten når denne er samlet. Dermed opnås en ekstra beskyttelse i tilfælde af at der skulle gå hul gå fibermembranen eller det fleksible lag. Frembringelsen angår desuden fremgangsmåder til etablering af en støjskærm ifølge frembringelsen.Only one flexible layer can be arranged in the frame, either behind the front or rear fiber membrane. Alternatively, a flexible layer may be arranged behind both fiber membranes. The flexible layer can be attached to the fiber membrane and / or the frame itself during the assembly of the cassette, or be mechanically fixed in the cassette when it is assembled. This provides extra protection in the event of a hole in the fiber membrane or the flexible layer. The invention further relates to methods for establishing a noise screen according to the invention.
En fremgangsmåde til etablering af støjskærmen består i at tilvejebringe støtter eller stolper forankret i et underlag som jorden; at tilvejebringe skærmelementer, fortrinsvist kasseformede skærmelementer, mellem støtter eller stolper; at indblæse granulat i de fortrinsvist kasseformede skærmelementer, og hvor kassetter 1 skærmelementerne er udført med en valgfri lem, låge eller tilsvarende midler til tømning og/eller fyldning af granulatet. En alternativ fremgangsmåde til etablering af støjskærmen består i at tilvejebringe flere støtter eller stolper forankret i et underlag som jorden; at tilvejebringe flere skærmelementer, fortrinsvist kasseformede skærmelementer, mellem støtter eller stolper på en sådan vis, at flere skærmelementer er forbundet med en kanal; hvorefterOne method of establishing the noise shield is to provide supports or posts anchored in a substrate such as the ground; providing screen elements, preferably box-shaped screen elements, between supports or posts; blowing granules into the preferably box-shaped screen elements, and wherein cassettes 1 the screen elements are made with an optional limb, door or similar means for emptying and / or filling the granulate. An alternative method of establishing the noise screen is to provide several supports or posts anchored in a substrate such as the ground; providing several screen elements, preferably box-shaped screen elements, between supports or posts in such a way that several screen elements are connected to a channel; after which
DK 202100102 U3 6 der indblæses granulat i flere skærmelementer. Kassetten kan med fordel være udstyret med mindst to lag af et permeabelt, fleksibelt materiale, der tilsammen dannet en lukket afgrænset lomme til opbevaring af granulatet. Lommen kan være forbundet til indblæsningsåbningen så granulatet kan blæses direkte ind 1 lommen og hvor indblæsningsluften kan ledes ud gennem det fleksible materiale. Kassetten kan være udformet så de to fleksible lag mekanisk fikseres til hinanden langs kanterne, når kassetten lukkes.DK 202100102 U3 6 Granules are blown into several screen elements. The cassette can advantageously be equipped with at least two layers of a permeable, flexible material, which together form a closed delimited pocket for storing the granulate. The pocket can be connected to the supply opening so that the granulate can be blown directly into the pocket and where the supply air can be led out through the flexible material. The cassette can be designed so that the two flexible layers are mechanically fixed to each other along the edges when the cassette is closed.
Kassetten kan alternativt være udstyret med en pose af et permeabelt, fleksibelt materiale, hvori granulatet blæses direkte ind i posen i kassetten. Eventuel komprimering af granulatet sker dermed alene ved hjælp af indblæsningsluften. Alternativt kan granulatet indblæses i posen før denne lukkes og placeres i kassetten. Herefter afsluttes samlingen af kassetten.The cassette may alternatively be provided with a bag of a permeable, flexible material in which the granulate is blown directly into the bag in the cassette. Any compaction of the granulate is thus done solely by means of the supply air. Alternatively, the granulate can be blown into the bag before it is closed and placed in the cassette. The assembly of the cassette is then completed.

DK 202100102 U3 7 jorden, og hvorimellem de i hovedsagen vandret forløbende skærmelementer er monteret. Kassetten består af profilerede metalplader 4, der eksempelvis er tyndvæggede, samt en opfyldt kerne 9 af et lydabsorberende granulatmateriale. Støjskærmen 10 kan som vist også omfatte forskellige profilplader, 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 støj-skærm 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 sidestykker 6, der sammenføjes til en formstabil og selvbærende ramme. Den interne afstivning 8 sikrer, at kassetten forbliver stabil.DK 202100102 U3 7 the ground, and between which the substantially horizontally extending screen elements are mounted. The cassette consists of profiled metal plates 4, which are, for example, thin-walled, as well as a filled core 9 of a sound-absorbing granular material. As shown, the noise shield 10 may also comprise various profile plates, corrugated trapezoidal plates which form a mechanical barrier and front of the screen 10. Common to all the plates mounted on the front is that they are perforated to some degree and extent. It will be extremely simple to provide equipotential bonding of all metal parts in a noise screen of the type described, so that it also becomes 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 dimensionally stable and self-supporting frame. The internal bracing 8 ensures that the cassette remains stable.
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. Et lag af et fleksibelt, permeabelt materiale kan være arrangeret bag ved fibermembranen (ikke vist på figur) for ekstra beskyttelse imod at granulatet falder ud af revner/huller i fibermembranen.To hold on to the granulate 9, a mechanical net 4 is mounted. Behind this net a permeable fiber membrane 3 is mounted. The fiber membrane allows the passage of the supply air, but at the same time retains the blown granulate. A layer of a flexible, permeable material may be arranged behind the fiber membrane (not shown in the figure) for extra protection against the granulate falling out of cracks / holes in the fiber membrane.
