Description
GELUIDABSORBERENDE WANDSOUND ABSORBING WALL
De uitvinding betreft een geluidabsorberende wand voor het absorberen van verkeerslawaai.The invention relates to a sound-absorbing wall for absorbing traffic noise.
De bekende geluidabsorberende wanden zijn in het algemeen goed voor het absorberen van de hoge tonen, zoals 1000-2000 Hz, uit het geluidsspectrum, maar dempen onvoldoende de lage tonen, zoals 60-125 Hz, die voortkomen uit bandenlawaai en motorlawaai van vrachtverkeer.The known sound absorbing walls are generally good at absorbing the high tones, such as 1000-2000 Hz, from the sound spectrum, but insufficiently attenuate the low tones, such as 60-125 Hz, which arise from tire noise and engine noise from freight traffic.
In dit opzicht verschaft de uitvinding een verbeterde geluidabsorberende wand, die in conclusie 1 is aangeduid.In this regard, the invention provides an improved sound-absorbing wall, which is indicated in claim 1.
Verdere kenmerken van voorkeursuitvoeringsvormen van deze geluidabsorberende wand blijken uit de hierna volgende beschrijving aan de hand van tekeningen. In de tekeningen stellen schematisch voor:Further features of preferred embodiments of this sound-absorbing wall are apparent from the following description, with reference to drawings. The drawings schematically represent:
Figuur 1 een perspectivisch aanzicht van een geluidabsorberende wand volgens de uitvinding ter plaatse van een viaduct;Figure 1 shows a perspective view of a sound-absorbing wall according to the invention at the location of a viaduct;
Figuur 2 op grotere schaal een vertikale doorsnede over lijn II-II van figuur 1;Figure 2 is an enlarged vertical section along line II-II of figure 1;
Figuur 3 op grotere schaal een horizontale doorsnede over lijn III-III van figuur 2;Figure 3 is an enlarged horizontal section along line III-III of Figure 2;
Figuur 4-6 een met figuur 3 overeenkomende doorsnede door drie andere uitvoeringsvarianten van de geluidabsorberende wand volgens de uitvinding; enFigures 4-6 show a cross-section corresponding with figure 3 through three other embodiments of the sound-absorbing wall according to the invention; and
Figuur 7 op kleinere schaal een aanzicht van figuur 5.Figure 7 shows a view of figure 5 on a smaller scale.
De geluidabsorberende wand 1 van figuren 1-3 wordt langs een verkeersweg 9 opgesteld en heeft een in de grond 2 reikende steunconstructie 3, bestaande uit een plateau 4 en vertikale steunen 5. Daarop staat een steunbeerconstructie 6 van gewapende constructiebeton of staal en daartegen steunt de geluidabsorberende wandconstructie 7, die opgebouwd is uit drie platen 18, die onderling een stompe hoek insluiten, zodat de naar de verkeersweg 9 gerichte zijde 10 hol is. De platen 18 grijpen met een complementaire voeg 11 in elkaar en in een voetbalk 12. De platen 18 hebben aan hun voorzijde panelen 8 die vervaardigd zijn van openstructuurbeton. De panelen bestaan uit een gesloten achterwand 13 en een daaraan als één geheel verbonden T-vormig bouwelement, waarvan de flens 14 als paneel 8 naar de verkeersweg 9 is gekeerd. De flenzen 14 bevinden zich op een onderlinge spleetafstand a van 25, 15, 35 of 50 mm. Achter de flenzen 14 bevinden zich T-vormige holten 15, waarin volgens figuur 3 vezelvormig materiaal, bijvoorbeeld glaswol, mineraalwol of dergelijk geluidabsorberend zacht materiaal 16 is opgenomen.The sound-absorbing wall 1 of figures 1-3 is arranged along a traffic road 9 and has a supporting structure 3 extending into the ground 2, consisting of a plateau 4 and vertical supports 5. On this is supported a supporting structure 6 of reinforced structural concrete or steel and against which the sound-absorbing wall construction 7, which is built up of three plates 18, which mutually enclose an obtuse angle, so that the side 10 facing the traffic route 9 is hollow. The plates 18 interlock with a complementary joint 11 and in a foot beam 12. The plates 18 have panels 8 on their front side which are made of open-structure concrete. The panels consist of a closed rear wall 13 and a T-shaped building element connected to it as a whole, the flange 14 of which faces panel 9 as panel 8. The flanges 14 are at a mutual gap distance a of 25, 15, 35 or 50 mm. Behind the flanges 14 are T-shaped cavities 15, in which, according to Figure 3, fibrous material, for example glass wool, mineral wool or the like, sound-absorbing soft material 16 is incorporated.
De geluidabsorberende wand volgens de uitvinding heeft een esthetisch verantwoord uiterlijk.The sound-absorbing wall according to the invention has an aesthetically pleasing appearance.
De wandelementen 19 worden tegen elkaar aangeschoven onder tussenvoeging van isolatiemateriaal. Het eventuele zand wordt er van boven via een desbetreffende opening ingestort.The wall elements 19 are pushed together while inserting insulating material. Any sand is poured in from above through a corresponding opening.
Bij de uitvoeringsvariant van figuur 4 zijn eerst panelen 8 van open betonstructuur vervaardigd, waarbij bevestigingswapening 20 van wapening 21 buiten de panelen 8 uitsteekt. Daarna wordt er een bouwelement 23 vervaardigd door een reeks panelen 8 op een vlak op onderlinge afstand a te leggen en door lichamen van geluidabsorberend materiaal 16, bijvoorbeeld opencellig, elastisch polyurethaanschuim, daarop te leggen. Vervolgens wordt wapening 24 van de achterwand 13 gesteld en aan de bevestigingswapening 20 bevestigd en dan wordt het constructiebeton 25 van de achterwand 13 gestort. De fabrieksmatig, in serie vervaardigde bouwelementen 23 worden naar de bouwplaats getransporteerd en daar opgesteld, bijvoorbeeld volgens figuur 2, hetzij in gebogen vlak, hetzij in recht vlak.In the embodiment variant of figure 4, panels 8 of open concrete structure are first manufactured, wherein fixing reinforcement 20 of reinforcement 21 protrudes outside panels 8. Subsequently, a building element 23 is manufactured by placing a series of panels 8 on a plane at a mutual distance a and by placing bodies of sound-absorbing material 16, for example, open-cell, elastic polyurethane foam thereon. Then reinforcement 24 of the rear wall 13 is set and attached to the fixing reinforcement 20 and then the construction concrete 25 of the rear wall 13 is poured. The factory-built construction elements 23 in series are transported to the construction site and arranged there, for example according to figure 2, either in curved plane or in straight plane.
De varianten van figuren 5 en 6 hebben aan de naar de verkeersweg toegekeerde zijde een andere configuratie. In plaats van vlakke panelen 8 zijn hier dakvormige panelen 8 toegepast, die het geluid nog beter tussen zich opvangen en naar het zachte geluidabsorberende materiaal toe geleiden.The variants of figures 5 and 6 have a different configuration on the side facing the traffic road. Instead of flat panels 8, roof-shaped panels 8 are used here, which absorb the sound even better between them and conduct it towards the soft sound-absorbing material.
Er wordt ook een fraai reliëf verwezenlijkt met naar de verkeersweg toe uitpuilende uitsteeksels 26 met schuine vlakken 27.A beautiful relief is also realized with protrusions 26 with oblique surfaces 27 protruding towards the traffic road.
De maten en dimensies in mm die als voorbeeld worden gegeven zijn aan de tekening te ontlenen. Die maten kunnen binnen hun ordegrootte flink variëren.The dimensions and dimensions in mm that are given as an example can be derived from the drawing. These sizes can vary considerably within their order of magnitude.
