Meluaita - Bullerstångsel Tåmån keksinnon kohteena on kulkuvaylien liikennemelun le-5 viåmista rajoittava meluesteaita ja erityisesti melua absor-boiva aitapaneeli, joka koostuu pintalevyistå ja niiden vå-lissa olevasta mineraalivillaa tai vastaavaa materiaalia olevasta tåytteestå, jolloin ainakin melulåhteen puoleinen pintalevy on rei'itetty.The present invention relates to a noise barrier, and in particular to a noise-absorbing fence panel, consisting of surface plates and a filling of mineral wool or similar material between them, wherein at least

Suomalaisessa rakennustietokortissa RT X70-33887 kuvataan yleisesti tunnettu meluesteaitarakenne, joka muodostuu pyl-vaistå ja pylvaiden valiin asetetuista metallilevykuorisista mineraalivillatåytteisistå paneelielementeistå. Luontaisesti 15 tallainen aita heijastaa siihen kohdistuvan liikennemelun takaisin. Tavallisesti liikenteen puoleinen meluaitapaneelin kuori on rei'itetty, jolloin mineraalivilla paneelin sisallå absorboi melua. Aitapaneeli valmistetaan hyvin korroosiota keståvåksi. Perinteisesti paneelin sisållå mineraalivilla 20 saa kastua ja kuivua sååvaihteluiden mukana. Ilmeisesti ainakin joissakin melutilanteissa kastunut mineraalivilla vai-mentaa suuremman massansa ansiosta paremmin kuin kuivana.The Finnish building data card RT X70-33887 describes a well-known noise barrier structure consisting of column elements and metal wool-filled panel elements filled with metal plate shells placed between the columns. Inherently, such a fence reflects back the traffic noise on it. Usually, the shell of the traffic side noise barrier panel is perforated, whereby the mineral wool inside the panel absorbs noise. The fence panel is made to be very corrosion resistant. Traditionally, the mineral wool 20 inside the panel is allowed to get wet and dry with weather variations. Apparently, at least in some noise situations, wetted mineral wool dampens better than dry due to its higher mass.
Vaikka edellå kuvattu meluestepaneeli toimii ja keståå låm-25 pimåsså ilmastossa hyvin, on sen keståvyyden uhkana jååtymi-nen erityisesti Suomen ja yleenså kylmien maiden olosuhteis-sa. Paneelin sisåån rei'ityksen kautta satanut vesi jååtyy såån pakastuessa ja tunnetusti vesi jååtyessåån laajenee. Mårkå, jååtyvå mineraalivilla laajenee ja pullistaa aita-30 paneelia. Kun sopivissa olosuhteissa kerros paneelin pinnan sisåpuolelta sulaa ja jååtyy taas uudelleen, jååtyminen kuormittaa paneelia yhå lisåå ja voi jopa rikkoa paneeliele-mentin. Mineraalivillakin voi aikaa myoten murentua jååtyessåån ja sulaessaan vuorotellen.Although the noise barrier panel described above works and withstands well in warm-25 dark climates, its durability is threatened by freezing, especially in the conditions of Finland and cold countries in general. The water that has fallen inside the panel through the perforation freezes as the ice freezes and it is known that the water expands as it freezes. Wet, frozen mineral wool expands and bulges the fence-30 panel. When, under suitable conditions, the layer inside the surface of the panel melts and re-freezes again, the freezing loads the panel even more and can even break the panel element. Mineral wool can also crumble over time as it freezes and thaws alternately.

Nyt on tultu siihen tulokseeny ettå Suomen ilmastossa me-luestepaneelin tulee pååstå kuivumaan sisåltå ja mårkånåkin .· sisåltåå jååtymiselle altista vettå mahdollisimman våhån.It has now come to the conclusion that in the Finnish climate, the barrier panel will be allowed to dry on the inside and even when wet.
2 923422,92342
Keksinnon tavoitteena on siten aikaansaada meluaitapaneeli, y joka kuivuu sisalta mahdollisimman nopeasti kastuttuaan, ja jonka mineraalivillatåytteen kastuminen olisi hidasta.The object of the invention is thus to provide a noise barrier panel, which dries on the inside as soon as possible after wetting, and in which the wetting of the mineral wool filling would be slow.
5 Tamån aikaansaamiseksi on keksinndn mukaiselle meluaita- paneelille tunnusomaista se, mita on mååritelty patenttivaa-timuksen 1 tunnusmerkkiosassa.To achieve this, the noise barrier panel according to the invention is characterized by what is defined in the characterizing part of claim 1.
Keksinnon oleellisena etuna on meluaitapaneelin sisåpuolisen 10 mineraalivillalevyn tai vastaavan pysyminen kuivana tai ai-nakin suhteellisen kuivana, jolloin ei ilmene jååtymisestå aiheutuvia ongelmia tai vaurioita.An essential advantage of the invention is that the mineral wool board 10 or the like inside the noise barrier panel remains dry or at least relatively dry, whereby no problems or damage due to freezing occur.
Seuraavassa keksintoå selostetaan oheisiin piirustuksiin 15 viittaamalla.The invention will now be described with reference to the accompanying drawings.
Kuvio 1 esittaa keksinnon mukaista meluaitapaneelia ak-sonometrisesti paneelin paadysta pain katsottuna.Figure 1 shows an axonometric view of a noise barrier panel according to the invention from the panel.
20 Kuvio 2 esittaa meluaitapaneelien sijoitusta kannatuspila-reihin ylhaålta påin kuvion 1 suunnasta I.Fig. 2 shows the arrangement of the noise barrier panels in the support columns from above in the direction I of Fig. 1.
Edella kuvattu keksinnon tavoite saavutetaan, kun pååstetåån rei'ityksen 3 kautta tullut vesi valumaan aitapaneelin 1 25 alaosaan 5 jarjestettyyn tyhjaån kokoojatilaan 6 ja panee-lissa olevista aukoista 7 pois. MineraalivillatMytteestå 4 9 vapaa kokoojatila voidaan jarjeståM periaatteessa monella tavalla eståmållå mineraalivillalevyå 4 valumasta paneelin alareunaa 8 vasten. Kokoojatila on elementin massasta pois 30 ja siten jonkin verran heikentaa meluestepaneelin vaimen- nusominaisuuksia, mutta kaytannossa tålla ei ole merkitystå. Paneelin rei'itetyn pinnan 3 vieresså oleva våli S våhentåå mineraalivillan kastumista ja lisåå ilmanvaihtoa reikien ja kokoojatilan kautta tehostaen nåin kuivumista.The object of the invention described above is achieved when the water entering through the perforation 3 is allowed to drain into the empty collector space 6 arranged in the lower part 5 of the fence panel 1 and out of the openings 7 in the panel. Mineral wool The collection space free of the sample 4 9 can in principle be arranged in many ways by preventing the mineral wool plate 4 from running against the lower edge 8 of the panel. The collector space is out of the mass of the element 30 and thus somewhat impairs the attenuation properties of the noise barrier panel, but in use this is irrelevant. The gap S next to the perforated surface 3 of the panel reduces the wetting of the mineral wool and increases the ventilation through the holes and the collection space, thus enhancing the drying.

Keksinnon mukaisesti aitapaneelin 1 kokoojatila 6 on erityi-sesti muodostettu rei'itetystå putkesta, edullisesti kaupal-. lisesti saatavasta muovisesta salaojaputkesta. Tållainen 3 92342 salaojamuoviputki on halpaa sekå valmiiksi uritettua ja rei'itettyå. Tama rei'itetty putki on sijoitettu paneelin alaosaan 5 lepååmåån paneelin pohjan 8 påålle. Kokoojatilan 6 muodostava rei'itetty muoviputki ulottuu yleensa paneelin 5 koko pituudelle L ainakin melko låhelle paneelin pååtyjå, joita on yleisesti merkitty viitenumeroilla 9a, 9b. Veden-poisto aitapaneelin metallikuorien 2 ja 3 vålistå voidaan jårjeståå paneelin keskeltåkin, mutta edullista on sijoittaa paneelin påihin 9a, 9b alanurkkiin valumareiåt 7. Aitapanee-10 li 1 on påiståån 9a, 9b sinånså tunnetun rakenteen mukaises-ti pilarien 10 ymparoimånå pilarien urassa 11, jolloih vesi valuu pilarin sisålle tahraamatta paneelin ulkosivuja 2, 3. Aitapaneelissa voidaan pohja 8 sekå ainakin toinen pintalevy 2 tai 3 alareunastaan 5, siinå tapauksessa, ettå pohja on 15 vino kuten kuviossa 1 on esitetty, tai molemmat pintalevyt 2 ja 3 alareunoistaan, siinå tapauksessa, ettå pohja 8 on poikkisuunnassa suora, jårjeståå rei'ittåmåttomåksi veden suoraan ulos valumisen eståmiseksi ja veden ohjaamiseksi paneelin påihin. Veden poistoreiåt 7 paneelin påisså voivat 20 olla joko kokoojatilan 6 muodostavien putkien påitå tai ku-vioissa ei esitetyn paneelin 1 mahdollisen pååtylevyn ala-reunassa olevia reikiå.According to the invention, the collector space 6 of the fence panel 1 is in particular formed of a perforated pipe, preferably commercially. plastic drainage pipe. Such a 3 92342 drainage plastic pipe is cheap as well as pre-grooved and perforated. This perforated tube is placed in the lower part 5 of the panel resting on the base 8 of the panel. The perforated plastic tube forming the collector space 6 generally extends over the entire length L of the panel 5 at least quite close to the ends of the panel, which are generally indicated by reference numerals 9a, 9b. Dewatering between the metal shells 2 and 3 of the fence panel can be arranged also in the middle of the panel, but it is advantageous to place drainage holes 7 in the lower corners of the panel ends 9a, 9b. in which case water flows into the column without staining the outer sides 2, 3 of the panel. that the base 8 is straight in the transverse direction, arranges the perforations to prevent water from flowing out directly and to direct the water to the ends of the panel. The water drainage holes 7 at the ends of the panel 20 can be either at the end of the pipes forming the collecting space 6 or at the bottom of a possible end plate of the panel 1, not shown in the figures.
Edullisesti aitapaneelin pintalevyt 2, 3 ovat metallia ja 25 erityisesti muovipinnoitettua teråsohutlevyå. Sen ansiosta edullisesti aitapaneelin 1 rei'ityksen 13 reikien låvistyk-sestå jååneet levyosaset 12 voidaan jåttåå rei'itettyyn pin-talevyyn 3 kiinni ja saattaa osoittamaan paneelin sisåpuo-lelle, ts. toista pintalevyå 2 kohti. Tålloin levyosaset 12 30 pitåvåt mineraalivillatåytteen 4 pienen vålimatkan S pååsså pintalevystå, jolloin paneelin sisåtilan tuuletus tehostuu.Preferably, the surface plates 2, 3 of the fence panel are made of metal and in particular of plastic-coated steel sheet. As a result, preferably the plate parts 12 left by the perforation of the holes 13 in the perforation panel 1 can be left attached to the perforated surface plate 3 and made to point inside the panel, i.e. towards the second surface plate 2. In this case, the plate parts 12 30 keep the mineral wool filling 4 at a small distance S from the surface plate, whereby the ventilation of the interior of the panel is improved.
Mineraalivillan sijasta voidaan tietysti kåyttåå muuta ååntå vaimentavaa ja kyseiset olosuhteet keståvåå vastaavaa mate-35 riaalia.Instead of mineral wool, it is of course possible to use another material which dampens the sound and which can withstand the conditions in question.
Keksinnon tehokkuutta ja toimivuutta lisååvåt tuuliolo-: suhteet. Aitaa vasten puhaltavan tuulen paine ajaa ilmaa 92342 4 rei'ityksen 13 kautta mineraalivillan 4 låpi kokoojaputkeen 6, jolloin elementti tuulettuu kuivaksi.The efficiency and functionality of the invention are increased by wind conditions. The pressure of the wind blowing against the fence drives the air 92342 4 through the perforation 13 through the mineral wool 4 into the collecting pipe 6, whereby the element is ventilated to dryness.
