Description
Oppfinnelsens område Field of the invention
Foreliggende oppfinnelse vedrører et system for håndtering av overvann. The present invention relates to a system for handling storm water.
Bakgrunn Background
Overvann er en fellesbetegnelse på vann som renner av takflater, veier og plasser som følge av regn og snøsmelting. Overvannet samles i overvannsledninger, men kombinasjonen av kraftig regn og fortetning vil ofte skape en utfordring ved at rørsystemene overbelastes. Spesielt i byer og tettbygde strøk blir det etter hvert bygd tettere mens grønne områder arealer legges under asfalt og åpne bekker legges i rør. Man mener også at klimaendringer gjør at været blir våtere. Stormwater is a general term for water that runs off roof surfaces, roads and places as a result of rain and snowmelt. The stormwater is collected in stormwater lines, but the combination of heavy rain and condensation will often create a challenge by overloading the pipe systems. Especially in cities and densely built-up areas, buildings gradually become denser, while areas of green areas are laid under asphalt and open streams are laid in pipes. It is also believed that climate change is making the weather wetter.
Som følge av dette har flere kommuner innført krav om håndtering av overvann ved prosjektering av nybygg. Overvann kan ledes til bort til bekker og vassdrag i nærheten, infiltreres i grunnen eller føres til de kommunale overvannsledningene. I det siste tilfellet vil kommunen sette krav til fordrøyning av vannmengden som ledes til ledningsnettet, dvs. at utbyggeren tillates å tilføre en bestemt mengde vann per tidsenhet. Fordrøyningen kan i praksis utføres ved at takvannet føres til et nedgravd magasin før det gradvis slippes ut i ledningsnettet, eller ved at vannet magasineres på taket, enten direkte eller ved hjelp av såkalte grønne tak. As a result, several municipalities have introduced requirements for the handling of stormwater when designing new buildings. Stormwater can be diverted to nearby streams and waterways, infiltrated into the ground or led to the municipal stormwater lines. In the latter case, the municipality will set requirements for the reduction of the amount of water that is led to the mains, i.e. that the developer is allowed to add a certain amount of water per unit of time. In practice, the drainage can be carried out by taking the roof water to a buried tank before gradually releasing it into the mains, or by storing the water on the roof, either directly or with the help of so-called green roofs.
Nedgravde magasiner er en kostbar løsning, og kan også være vanskelig å få til på grunn av manglende arealer. Vannet kan også lagres direkte på taket, hvor selve takflaten anvendes som et basseng, og med intelligent styring av sluk, dvs. hvordan vannet slippes ut til ledningsnettet. Slike løsninger innebærer at det blir stående vanntrykk mot takbelegget, i det minste i en periode. Dette er uheldig og en invitasjon til senere problemer. Ved et grønt tak legges det et lag stein- eller glassull på takdekket. På dette laget legges det grastorv eller torv med sedum (bergknapp, plante med stort vanninnhold som holder seg grønn hele sommeren og er brannhemmende). Ved regn vil både stein/glass-ullen og torva suge opp vann og holde på det i en periode mens det sakte renner ned i avløpsnettet. Også her vil det oppstå problemer med vanntrykk mot takdekket. Buried magazines are an expensive solution, and can also be difficult to achieve due to a lack of space. The water can also be stored directly on the roof, where the roof surface itself is used as a pool, and with intelligent control of drains, i.e. how the water is discharged to the mains. Such solutions mean that there will be standing water pressure against the roof covering, at least for a period. This is unfortunate and an invitation to later problems. In the case of a green roof, a layer of stone wool or glass wool is placed on the roof covering. On this layer, grass turf or turf with sedum (rock button, a plant with a high water content that stays green all summer and is fire retardant) is laid. In the event of rain, both the stone/glass wool and the peat will absorb water and hold it for a period while it slowly drains into the drainage network. Here, too, problems will arise with water pressure against the roof deck.

Sammenfatning av oppfinnelsen Summary of the Invention
Det er en hensikt med foreliggende oppfinnelse å frembringe et system for fordrøyning av takvann fra nedbør hvor det unngås vanntrykk mot eksisterende takbelegg. It is a purpose of the present invention to produce a system for draining roof water from rainfall where water pressure against existing roof covering is avoided.
Dette oppnås med et system slik det fremgår av de etterfølgende patentkrav. This is achieved with a system as shown in the subsequent patent claims.
Nærmere bestemt omfatter systemet ei oppsamlingsplate som legges på takflata, hvor oppsamlingsplata omfatter et antall kopper og hvor det er anordnet åpninger mellom en øvre kant av hver kopp, og veker som går fra bunnen av hver kopp, gjennom en åpning og ned til takflata. Derved oppnås det at regnvann først samles opp og magasineres i koppene før det sakte føres av vekene ned til selve taket. More specifically, the system includes a collection plate that is placed on the roof surface, where the collection plate comprises a number of cups and where openings are arranged between an upper edge of each cup, and wicks that run from the bottom of each cup, through an opening and down to the roof surface. Thereby, it is achieved that rainwater is first collected and stored in the cups before it is slowly carried by the wicks down to the roof itself.
Ifølge en utførelse av oppfinnelsen er det anordnet ei sekundær plate med kopper av tilsvarende størrelse som i oppsamlingsplata, idet hver kopp er perforert i bunnen, og den sekundære plata legges over vekene og ned i oppsamlingsplata. According to one embodiment of the invention, a secondary plate is arranged with cups of a similar size as in the collection plate, each cup being perforated at the bottom, and the secondary plate is placed over the wicks and down into the collection plate.
Ifølge en ytterligere utførelse er det anordnet midler som skaper avstand mellom platene. According to a further embodiment, means are arranged which create a distance between the plates.
Ifølge enda en utførelse er det lagt en filtduk oppå platene, samt et dekklag oppå filtduken. Dekklaget kan bestå av grus, gress, sedum, heller, kunstgress eller lignende. Selv om det er koppene i oppsamlingsplata som står for den største delen av magasineringsevnen, vil filtduken og dekklaget i noen grad bidra til at taket får enda større evne til å ta opp vann. According to yet another embodiment, a felt cloth is placed on top of the plates, as well as a covering layer on top of the felt cloth. The cover layer can consist of gravel, grass, sedum, pebbles, artificial grass or the like. Although it is the cups in the collection plate that account for the largest part of the storage capacity, the felt cloth and the covering layer will to some extent contribute to the roof's even greater ability to absorb water.

Detaljert beskrivelse Detailed description
Fig. 1 viser et takbelegg. Taket er i tillegg utstyrt med et avløp som er ført til avløpsnettet (ikke vist). Fig. 1 shows a roof covering. The roof is also equipped with a drain which is led to the drainage network (not shown).
På takflata er det lagt ei oppsamlingsplate 2 med kopper 3. I toppen av plata og mellom den øvre kanten av hver kopp er det en åpning 4. Plata er laget av plast. Fra bunnen av hver oppsamlingskopp 3 er det ført en veke 5 opp langs siden av koppen, gjennom åpningen 4 og ned til takflata. Vekene 5 kan være dannet av en spesialfilt med drenerende egenskaper, for eksempel i form av en hel duk hvor det er stanset ut passende remser som stikker ned i koppene 3 og ned til takflata. Når det regner på taket, vil vannet først samles opp i koppene 3 før det tas opp av vekene 5 og føres ned til selve takflata. Ved at vannet føres via vekene vil det oppstå en fordrøyning før det går i avløpet. Det vil ikke oppstå noe direkte vanntrykk mot takbelegget idet dette tas opp av koppene 3. Vekene vil overføre vann til takflata i et tempo som avløpet hele tiden tar unna. A collection plate 2 with cups 3 is placed on the roof surface. At the top of the plate and between the upper edge of each cup there is an opening 4. The plate is made of plastic. From the bottom of each collection cup 3, a wick 5 is led up along the side of the cup, through the opening 4 and down to the roof surface. The wicks 5 can be formed from a special felt with draining properties, for example in the form of a whole cloth where suitable strips have been punched out that stick into the cups 3 and down to the roof surface. When it rains on the roof, the water will first be collected in the cups 3 before it is taken up by the wicks 5 and led down to the roof surface itself. As the water is led via the wicks, a delay will occur before it goes down the drain. There will be no direct water pressure against the roof covering as this is taken up by the cups 3. The wicks will transfer water to the roof surface at a rate that the drain is constantly taking away.
På denne vekefilten 5 kan det være lagt ei sekundær plate 6 av tilsvarende form og type som oppsamlingsplata, men hvor hver kopp 7 er perforert i bunnen. Den sekundære plata tjener til å holde vekefilten 5 på plass. For å få plass til vekene, dvs. hindre vekene å presses mellom koppene i oppsamlingsplata og den sekundære plata, kan det anordnes midler som skaper en avstand mellom platene. Midlene kan bestå av brikker 10 som plasseres i bunnen av hver kopp i oppsamlingsplata. Brikkene kan være runde, firkantede, kryssformede eller rammeformede. En annen løsning er å lage en forhøyning i sentrum av hver kopp i oppsamlingsplata. Enda en løsning er å lage utspring i de nedre hjørnene i hver kopp i oppsamlingsplata. Denne løsningen vil i tillegg sentrere den sekundære plata i forhold til oppsamlingsplata. A secondary plate 6 of a similar shape and type to the collection plate, but where each cup 7 is perforated at the bottom, can be placed on this wicking felt 5. The secondary plate serves to hold the wicking felt 5 in place. In order to make room for the wicks, i.e. prevent the wicks from being pressed between the cups in the collection plate and the secondary plate, means can be arranged which create a distance between the plates. The means can consist of chips 10 which are placed at the bottom of each cup in the collection plate. The pieces can be round, square, cross-shaped or frame-shaped. Another solution is to create an elevation in the center of each cup in the collection plate. Another solution is to create protrusions in the lower corners of each cup in the collection plate. This solution will also center the secondary plate in relation to the collecting plate.
Ovenpå dette igjen kan det være lagt en filtduk 8. Filtduken 8 er relativt tykk og dekker over de underliggende plastplatene med kopper. Filtduken 8 danner underlag for et dekklag 9 med drenerende egenskaper. Dekklaget kan bestå av ethvert materiale som er permeabelt for vann, slik som grus eller kunstgress. Dekklaget kan også bestå av torv som er bevokst med gress eller andre vekster. Fortrinnsvis kan torva være beplantet med sedum. Filtduken og dekklaget dekker over platene 2, 6 og skjuler koppene med videre. Videre vil både duken og dekklaget ha noe evne til å ta opp vann og derved øke oppsamlingskapasiteten til systemet. Valg av materiale i dekklaget gir mulighet for å oppnå ulik dreneringshastighet. I tillegg kan dekklaget oppta og filtrere vekk forurensing som faller ned på taket, slik som svevestøv, i tillegg til pollen og løv. On top of this again, a felt cloth 8 can be laid. The felt cloth 8 is relatively thick and covers the underlying plastic plates with cups. The felt cloth 8 forms a base for a cover layer 9 with draining properties. The cover layer can consist of any material that is permeable to water, such as gravel or artificial grass. The cover layer can also consist of peat covered with grass or other vegetation. Preferably, the turf can be planted with sedum. The felt cloth and the cover layer cover the plates 2, 6 and hide the cups etc. Furthermore, both the fabric and the cover layer will have some ability to absorb water and thereby increase the collection capacity of the system. The choice of material in the cover layer makes it possible to achieve different drainage rates. In addition, the cover layer can absorb and filter away pollution that falls on the roof, such as airborne dust, in addition to pollen and leaves.
Fig. 2 viser hvordan de enkelte komponentene i systemet kan være dannet av sammenhengende plater og lag. Fig. 2 shows how the individual components in the system can be formed from connected plates and layers.
