TERMISK ISOLERENDE BRØNDDÆKSEL AF PLAST Forklaring af frembringelsenTHERMAL INSULATING PLASTIC SURFACE COVER Explanation of production
Ved anbringelse af en vandmåler eller lignende i en i jorden nedgravet målerbrønd er det nødvendigt, at brønddækslet har en række særlige egenskaber, så målerinstallationen i brønden kan holdes frostfri om vinteren under anvendelse af jordvarmen fra undergrunden.When installing a water meter or the like in a buried soil well, it is necessary that the well cover has a number of special features so that the meter installation in the well can be kept frost-free in winter using the soil heat from the underground.
For det første skal dækslet være termisk isolerende, så kulden ovenfra ikke kan trænge ned i brønden. Desuden skal dækslet være udformet således, at vejrligsændringer, blæst, nedbør, opstigende vand m.v. ikke kan fjerne dækslet fra brøndens munding, hvorefter installationen er frit tilgængelig for frost m.v. Sådanne vandmålerinstallationer er nemlig ofte anvendt i forbindelse med ferieboliger m.v., som kan være uden opsyn i længere tid. Herudover skal dækslet have tilstrækkelig styrke, så det ikke ødelægges, når det belastes ovenfra.First, the cover must be thermally insulating so that the cold from above cannot penetrate the well. In addition, the cover must be designed so that weather changes, blows, rainfall, rising water, etc. can not remove the cover from the well's mouth, after which the installation is freely available for frost, etc. Such water meter installations are often used in connection with holiday homes, etc., which may be unattended for an extended period of time. In addition, the cover must be of sufficient strength so that it is not damaged when loaded from above.
Alle disse fordele opnås med dækslet ifølge frembringelsen, når dette udformes som nærmere angivet i kravene.All these advantages are achieved with the cover according to the invention, when designed as further specified in the claims.
Herudover får man et dæksel, hvor sammenkoblingen med brønden, når denne aflukkes, sker på en sådan måde, at dækslet sidder fast, men fortsat kan aftages for inspektion, måleraflæsning m.v. Med to ringformede pakninger i afstand fra hinanden afspærres et ringformet hulrum mellem dækslet og brøndens indervæg, så også den uundgåelige spalte mellem dækslet og brønden er tilstrækkeligt termisk isoleret, så jordvarmen holder målerinstallationen i brønden frostfri.In addition, a cover is provided where the connection to the well, when closed, occurs in such a way that the cover is stuck, but can still be removed for inspection, meter reading, etc. With two annular gaskets spaced apart, an annular cavity is blocked between the cover and the inside wall of the well, so that the inevitable gap between the cover and the well is insulated sufficiently thermally so that the soil heat keeps the meter installation in the well frost-free.
Herudover er dækslet ifølge frembringelsen udformet med mulighed for at kunne forsynes med en låseanordning, så kun personer med nøgle kan aftage brønddækslet. Aflåsning giver selvfølgelig også yderligere sikkerhed mod at dækslet kan fjernes ved voldsomme vejrligsændringer.In addition, the cover according to the invention is designed with the possibility of being provided with a locking device so that only persons with the key can take off the well cover. Locking of course also provides additional security against the cover being removed by severe weather changes.
Brønddækslet ifølge frembringelsen er fremstillet af plast, fortrinsvis af miljørigtig plast, der kan genbruges og som har den nødvendige styrke, f.eks. PEH plast. Brønddækslet ifølge frembringelsen består blot af to dele, nemlig en styrkegivende dækseldel og en bundplade, og brønddækslet kan således produceres ved støbning, f.eks. almindelig kendt sprøjtestøbning, således at det kan fremstilles til en konkurrencedygtig pris. Montagen af gummipakninger og indlægning af isoleringsmateriale er en ganske enkel operation, så disse heller ikke fordyrer det færdige produkt væsentligt. Det er selvfølgelig også muligt at vente med at ilægge isolering og at påsætte de elastiske gummipakninger indtil brønddækslet skal bruges, hvilket også har en række fordele.The well cover according to the invention is made of plastic, preferably of environmentally friendly, recyclable plastic which has the necessary strength, e.g. PEH plastic. The well cover according to the invention consists of only two parts, namely a strengthening cover part and a bottom plate, and the well cover can thus be produced by casting, e.g. commonly known injection molding so that it can be manufactured at a competitive price. The assembly of rubber gaskets and insulation material insulation is a simple operation, so that they do not significantly expensive the finished product. Of course, it is also possible to wait to install insulation and to apply the elastic rubber gaskets until the well cover is to be used, which also has a number of advantages.
Dækslet ifølge frembringelsen er udformet således, at der kan indføres et isolationsmateriale med en tykkelse på mindst 200 mm.The cover according to the invention is designed so that an insulating material with a thickness of at least 200 mm can be introduced.
Brønddækslet ifølge frembringelsen har i øvrigt en styrke, der er så stor, at det kan anvendes i såkaldt let kørebane med en belastning på mindst 1500 kg eller mere således, at dækslet kan godkendes i henhold til EU-norm nr. 124 i klasse A.The well cover according to the invention also has a strength so large that it can be used in so-called light carriages with a load of at least 1500 kg or more so that the cover can be approved according to EU standard No. 124 in Class A.

Frembringelsen forklares herefter nærmere under henvisning til tegningen, der viser en fortrukken udførelsesform for brønddækslet, idet fig. 1 viser skitsemæssigt et tværsnit i en jordinstallation med vandmåler i en brønd med låg ifølge frembringelsen, fig. 2 viser låget ifølge frembringelsen set ovenfra, fig. 3 viser et plant snit II-II i fig. 2 tfig. 4 viser låget ifølge frembringelsen set fra undersiden, fig. 5 viser et centralt, plant snit i låget i fig. 2 og fig. 4 efter linien V-V, fig. 6 viser en blindprop for afspærring af åbning i låget, og fig. 7 viser et låsesystem for låget ifølge frembringelsen.The production is then explained in more detail with reference to the drawing, which shows a preferred embodiment of the well cover, fig. 1 is a cross-sectional view of a ground installation with a water meter in a lid well according to the invention; 2 is a plan view of the lid according to the invention; FIG. 3 shows a plan section II-II in FIG. 2 tfig. 4 is a bottom view of the cover according to the invention; FIG. 5 is a central plan view of the lid of FIG. 2 and FIG. 4 along line V-V, FIG. 6 shows a blind plug for blocking the opening in the lid, and fig. 7 shows a locking system for the lid according to the invention.
Forklaring af udførelseseksemplet På fig. 1 ses en målerbrønd 2 nedgravet i jorden for afdækning og beskyttelse af en vandinstallation 3's vandmåler 4. Brønden er opadtil aflukket med et brønddæksel 1. Fig. 1 er udelukkende en skitse, der skal illustrere anvendelsen af brønddækslet ifølge frembringelsen, og brønddækslet forklares herefter nærmere under henvisning til tegningens fig. 2-7, der i detaljer viser brønddækslets opbygning.Explanation of the embodiment In fig. 1 shows a meter well 2 buried in the ground to cover and protect the water meter 4 of a water installation 3. The well is closed upwards with a well cover 1. FIG. 1 is merely a sketch illustrating the use of the well cover according to the invention, and the well cover is explained in greater detail with reference to FIG. 2-7 showing in detail the well cover structure.
Brønddækslet 1 består af en toppart 5, der i det væsentlige er plan, men kan være udformet som vist med ribber 7 for at gøre brønddækslets overside mere skridsikker. Ud-i-ét med topparten 5 er en rundtgående krave 14 indrettet til at omslutte mundingen på selve brønden, se fig. 1. Herudover omfatter brønddækslet en ringformet, nedadvendende del 15 ud-i-ét med topparten 5, hvilken del 15 danner et ringformet område under topparten 5. De nævnte dele er udformet ud-i- ét, fortrinsvis sprøjtestøbt i plast. Ud-i-ét med topparten 5 er ligeledes udformet et centralt - område 22 samt nedad-vendende, plane, radiale forstærkningsribber 17, som opdeler rummet under topparten 5 i et antal trekantlignende rum 21, hvori isoleringsmateriale kan anbringes. De radiale ribber 17 fortsætter i forlængelser 13 under den rundtgåen-de krave 14, hvilke forlængelser er indrettet til at hvile mod brønden 2's munding.The well cover 1 consists of a top portion 5 which is substantially planar, but may be configured as shown with ribs 7 to make the top of the well cover more non-slip. Out-of-one with the top part 5, a circular collar 14 is arranged to enclose the mouth of the well itself, see FIG. 1. In addition, the well cover comprises an annular downwardly extending portion 15 integrally with the top portion 5, said portion 15 forming an annular region below the top portion 5. Said portions are formed integrally, preferably injection molded in plastic. Also integral with the top portion 5 is a central region 22 as well as downwardly extending planar radial reinforcing ribs 17 which divide the space below the top portion 5 into a number of triangle-like compartments 21 into which insulating material may be placed. The radial ribs 17 continue in extensions 13 below the circumferential collar 14 which extends to rest against the mouth of the well 2.
Nedadtil er den ringformede del 15 aflukket med en bundplade 6 ligeledes af plast, hvilken bundplade, der i det væsentlige er plan, er udstyret med bøjelige dele 16 indrettet til at snappe ind i åbninger 20 i den ringformede del 15. Bunden 6 er således aftagelig, men er iøvrigt indrettet til at aflukke rummet under topparten 5, så isoleringsmaterialet forbliver i rummet.Downwardly, the annular portion 15 is enclosed with a bottom plate 6 also of plastic, the substantially planar bottom plate being provided with flexible portions 16 arranged to snap into openings 20 in the annular portion 15. The bottom 6 is thus removable. , but is otherwise arranged to seal the space below the top part 5 so that the insulating material remains in the space.
Udvendig på den ringformede del 15 er der anbragt to rundt-gående gummipakninger 18,19, hvor den ene gummipakning 18 kan være udformet og anbragt således, at den fastholdes af bunden 6, se fig. 5. Gummipakningerne 18,19 er af elastisk gummi og er anbragt i afstand fra hinanden, så der mellem pakningerne afspærres et hulrum, der sikrer, at kulde ovenfra ikke kan trænge ned i hulrummet i brønden, se fig. 1.Externally on the annular portion 15, two circumferential rubber gaskets 18,19 are provided, one of the rubber gaskets 18 being designed and positioned to be retained by the bottom 6, see FIG. 5. The rubber gaskets 18,19 are of elastic rubber and are spaced apart so that between the gaskets a cavity is blocked which ensures that cold from above cannot penetrate into the cavity of the well, see fig. First
De rundtgående, ringformede pakninger 18,19 er fortrinsvis udformet som vist på tegningens fig. 5, således at de, når dækslet påsættes brønden, bøjes opefter som vist på fig. 1, og herved yder kraftig modstand mod at brønddækslet aftages eller løftes bort på grund af vejrligsændringer, opstigende grundvand m.v. Da pakningerne imidlertid er udformet af elastisk gummi, plast, kunstgummi eller lignende, vil man dog, under deformering af pakningerne, kunne aftage dækslet. Pakningerne 18,19 er anbragt i en vis afstand fra hinanden, så at det ringformede luftrum afspærres, så at der ingen kuldebroer opstår mellem den kolde luft over dækslet og den indespærrede luft under dækslet, som bliver opvarmet af jordvarmen.The circumferential annular gaskets 18, 19 are preferably formed as shown in FIG. 5 so that when the cover is applied to the well, they bend upwards as shown in FIG. 1, thereby providing strong resistance to the well cover being removed or lifted due to weather changes, rising ground water, etc. However, since the gaskets are made of elastic rubber, plastic, artificial rubber or the like, it is possible, however, that the cover can be removed during deformation of the gaskets. The gaskets 18,19 are spaced apart so that the annular air space is blocked so that no cold bridges occur between the cold air above the cover and the trapped air under the cover which is heated by the ground heat.
Brønddækslets overside kan være forsynet med et område 8 for påsætning af et navn eller et logo.The top of the well cover may be provided with an area 8 for affixing a name or logo.
Herudover kan brønddækslet i området ved den rundtgående krave 14 omfatte midler, så brønddækslet kan fastlåses til brøndens munding, hvor der er fastgjort et udvendigt beslag 23, se fig. 1, f.eks. af rustfrit stål. Midlerne kan bestå i et gennemgående hul 9, hvori der enten kan indsættes en blindprop 10, se fig. 6 for afspærring af åbningen eller en lås 11, se fig. 7 for fastlåsning af brønddækslet i forhold til brønden 2 ved hjælp af en låsepal 12, se fig. 7.In addition, the well cover in the region of the circumferential collar 14 may comprise means so that the well cover can be locked to the mouth of the well, with an external bracket 23 attached, see FIG. 1, e.g. made of stainless steel. The means may consist of a through hole 9 in which either a blind plug 10 can be inserted, see fig. 6 for blocking the opening or a lock 11, see fig. 7 for locking the well cover relative to the well 2 by means of a locking pawl 12, see fig. 7th
Låsedelen 11 på fig. 7 omfatter et tværgående hul 25, f.eks. for anbringelse af en hængelås. Hovedet på låseparten 11 kan være udformet sekskantet for betjening med en • topnøgle eller for anden form for betjening med en specialnøgle, idet låsen 11’s hoved er omgivet af en stålkrave 24 således, at man ikke kan åbne låsen med et tilfældigt værktøj, f.eks. en rørtang eller lignende. Herudover er låsen selvfølgelig udformet således, at der ikke kan trænge vand ned gennem låsen.The locking part 11 of FIG. 7 comprises a transverse hole 25, e.g. for attaching a padlock. The head of the locking portion 11 may be hexagonal for operation with a • top wrench or for any other type of operation with a special wrench, the head of the latch 11 being surrounded by a steel collar 24 such that one cannot open the lock with a random tool, e.g. . a pliers or the like. In addition, the lock is of course designed so that no water can penetrate through the lock.
For at hindre, at brønddækslet i aflåst tilstand kan fjernes ved at dreje dækslet, er der på hver side af det gennemgående hul 9 anbragt en forstærkningsribbe 13', se fig. 1, ud-i-ét med resten af låget. Låseparten 23 hindrer herved dækslet i at kunne drejes, og samtidig hermed giver forstærkningerne 13' en yderligere forstærkning af dækslet i området omkring hullet 9, så der ikke indføres svækninger i låget på grund af hullet 9, men i stedet tilføres yderligere styrke til dækslet.To prevent the well cover in the locked state from being removed by turning the cover, a reinforcing rib 13 'is provided on each side of the through hole 9, see FIG. 1, out of line with the rest of the lid. The locking portion 23 thereby prevents the cover from being able to rotate, and at the same time the reinforcements 13 'provide a further reinforcement of the cover in the area around the hole 9, so that no weaknesses are introduced into the lid due to the hole 9, but instead additional strength is added to the cover.
