Beskrivelse af opfindelsen Teknisk problemDescription of the Invention Technical Problem

Der findes forskellige krav for åbninger af denne type.There are different requirements for openings of this type.

5 Hver åbning ma, inter alia, være simpel at installere og på trods af dette skabe en tætnet åbning, som forhindrer lækage fra det omgivende rum. Dette krav er specielt vigtigt i forbindelse med sterile rum, rene rum, og proces-rum. Endvidere må åbningen, set inde fra rummet have en 10 flad udformning som ikke samler støv for at gøre rengøring omkring åbningen lettere. Yderligere krav kan være at åbningen skal være i stand til at modstå høje temperaturer og udgøre en ensartet standardiseret installation. Opfindelsen søger at opfylde alle eller visse af disse 15 problemer.5 Each opening must, inter alia, be simple to install and despite this create a sealed opening that prevents leakage from the surrounding space. This requirement is especially important in connection with sterile spaces, clean rooms, and process rooms. Furthermore, the opening from the inside of the room must have a 10 flat design which does not collect dust to make cleaning around the opening easier. Further requirements may be that the opening must be able to withstand high temperatures and constitute a uniformly standardized installation. The invention seeks to meet all or some of these problems.

Det er også vigtigt at være i stand til at forhindre, at mekaniske kræfter spreder sig og påvirker den tætnende funktion eller selve åbningen, hvad der ofte er tilfældet 20 ved de såkaldte stive gennemføringer. Opfindelsen løser dette problem, og forhindrer også opvarmning, afkøling og/eller at vibrationer i elementet (rørledningen), som går igennem åbningen, fra at påvirke tætningen (den tætnende funktion) i nogen nævneværdig grad.It is also important to be able to prevent mechanical forces from spreading and affecting the sealing function or the opening itself, which is often the case in the so-called rigid penetrations. The invention solves this problem and also prevents the heating, cooling and / or vibration of the element (pipeline) passing through the orifice from affecting the seal (the sealing function) to any appreciable degree.

Ved åbninger af denne type er det ofte almindeligt at foreslå en udførsel, som kendetegnes ved flere komponenter, som skal samles og indsættes i forbindelse med installations arbejdet. Dette komplicerer installations arbejdet.In openings of this type, it is often common to propose an embodiment characterized by several components which must be assembled and inserted in connection with the installation work. This complicates installation work.

30 Det er ønskeligt, at det skal være muligt, at etablere en åbning ved brug kun af en let monterbar præfabrikeret komponent. Opfindelsen løser også dette ønske.It is desirable that it should be possible to establish an opening using only an easily assembled prefabricated component. The invention also solves this desire.

Fra FR-A-1 348 574 kendes en åbningsanordning som angivet 35 i den indledende del af krav 1 samt en fremgangsmåde som 3 DK 173465 B1 angivet i den indledende del af krav 14. Denne kendte anordning består af et stort antal dele som alle skal monteres i forbindelse med monteringen i den første åbning, for eksempel i en væg. Den kendte anordning er endvidere 5 udformet saledes, at den let samler støv ligesom den er vanskelig at rengøre.FR-A-1 348 574 discloses an opening device as defined in the preamble of claim 1 and a method as set forth in the preamble of claim 14. This known device consists of a large number of parts which all must mounted in connection with the mounting in the first opening, for example in a wall. The known device is furthermore designed so that it easily collects dust and is difficult to clean.

Løsning 10 Det ovenfor anførte problem er løst med en åbningsordning med de yderligere kendetegn som anført i krav l's kendetegnende del.Solution 10 The above-mentioned problem is solved with an opening arrangement with the additional features as set forth in the characterizing part of claim 1.

Den væsentlige egenskab ved den nye åbningsanordning er, 15 at den omfatter eller består af et pladeformet element udformet som en enkelt enhed, bestående af to pladeformede elementer mellem hvilke et tætningsorgan er monteret strækkende sig ind i den anden åbning, og som er udstyret med et fastholdelsesorgan, for eksempel klæbebånd. Ved 20 hjælp af dette organ kan det pladeformede element fæstes pa en eksisterende overflade på modulet således at den anden åbning er rettet ind med modulets første åbning.The essential feature of the new opening device is that it comprises or consists of a plate-shaped element formed as a single unit, consisting of two plate-shaped elements between which a sealing member is mounted extending into the second opening and which is provided with a retaining means, for example adhesive tape. By means of this means, the plate-shaped element can be fixed to an existing surface of the module so that the second opening is aligned with the first opening of the module.

Det pladeformede element indbefatter således en tætning, som strækker sig ind i den anden åbning, hvilken tætning 25 som ved indsætning af elementet (12) ind i den første og anden åbning danner en tætning mod ydersiden af elementet (rørforbindelsen, kablet, osv.). Det pladeformede element er også udformet til at blive tætnet mod den ovenfor nævnte overflade på modulet ved hjælp af tætnende midler 30 såsom lim, klæbemidler eller tilsvarende.The plate-shaped element thus includes a seal extending into the second opening, which seal 25 which, when inserting the element (12) into the first and second apertures, forms a seal against the outside of the element (pipe connection, cable, etc.). . The plate-shaped element is also designed to be sealed to the above surface of the module by sealing means 30 such as glue, adhesives or the like.

I en foretrukken udførselsform har det pladeformede element en højde i området 1,5-10 mm. I et eksempel pa en udførselsform er højden omkring 3 mm. Det pladeformede 35 element indbefatter en støtteflade, der kan monteres mod den ovenfor nævnte overflade på modulet. Åbningsanordnin- 4 DK 173465 B1 gen kan udformes således at den indbefatter et første og andet pladeformet element mellem hvilke tætningen for elementet er monteret. Det første og det andet pladeformede element, såvel som tætningen, har en gennemgående 5 åbning. Det første element kan i dette tilfælde udstyres med den ovenfor nævnte støtteflade. Det andet element strækker sig fortrinsvis ud over det første element og det tætnende organ er anbragt omkring periferierne af det første og andet pladeformede element. Det fikserende mid-10 del, som kan bestå af dobbeltsidet klæbebånd, er anbragt på de fremragende dele af det andet pladeformede element.In a preferred embodiment, the slab member has a height in the range of 1.5-10 mm. In one example of an embodiment, the height is about 3 mm. The plate-shaped element includes a support surface which can be mounted against the aforementioned surface of the module. The opening device 4 may be configured to include a first and second plate-shaped member between which the seal of the member is mounted. The first and second plate members, as well as the seal, have a through opening 5. In this case, the first element can be equipped with the support surface mentioned above. Preferably, the second member extends beyond the first member and the sealing member is disposed about the peripheries of the first and second plate members. The fixing middle part, which may consist of double-sided adhesive tape, is disposed on the protruding parts of the second plate-shaped element.

Den anden tætning kan være i form af en limet forbindelse, som strækker sig omkring periferien af de pladeformede elementer. I en foretrukken udførselsform er det pla-15 deformede element fremstillet af rustfrit stål, emaljeret plademetal eller polymer materiale. Det pladeformede elements tætning består af eller indbefatter et gummi eller elastomer materiale, som for eksempel kan være EPDM eller silikone. Set inde fra rummet har det pladeformede ele-20 ment en flad form som kun stikker en smule frem fra overfladen på modulet, dvs. loftet, gulvet, væggen, osv. Den flade form, som kun stikker en smule frem fra den ovenfor nævnte overflade betyder, at det er let at udføre rengøring og at ansamling af støv forhindres. Det pladeformede 25 element bruges til installationer ind i sterile rum, rene rum eller procesrum. Valget af materiale er derfor truffet således at åbningsanordningen kan modstå høje temperaturer, hvorved kan menes temperaturer på op til 145 °C i to timer.The second seal may be in the form of an adhesive bond extending around the periphery of the plate members. In a preferred embodiment, the sheet metal is made of stainless steel, enamelled sheet metal or polymeric material. The plate-shaped element seal consists of or includes a rubber or elastomeric material which may be, for example, EPDM or silicone. From the inside, the plate-shaped element has a flat shape which protrudes only slightly from the surface of the module, ie. the ceiling, the floor, the wall, etc. The flat shape, which protrudes only slightly from the surface mentioned above, means that cleaning is easy and dust collection is prevented. The plate-shaped 25 element is used for installations into sterile, clean or process rooms. Therefore, the choice of material is made so that the opening device can withstand high temperatures, which means temperatures of up to 145 ° C for two hours.

Det ovenfor anførte problem er tilsvarende løst med en fremgangsmåde med de yderligere kendetegn som anført i krav 14's kendetegnende del.The above-mentioned problem is similarly solved by a method with the additional features as set forth in the characterizing part of claim 14.

35 Fremgangsmaden i følge opfindelsen er således kendetegnet DK 173465 B1 5 ved at det pladeformet element med den anden gennemgående åbning er udformet som en enkelt enhed, bestående af to pladeformede elementer mellem hvilke et tætningsorgan er monteret strækkende sig ind i den anden åbning, og hvor 5 elementet kan fikseres, for eksempel ved limning, på en eksisterende overflade på det ovenfor nævnte modul, dvs. et loft, gulv, væg, osv., med den anden åbning rettet ind med den første åbning. Det pladeformede element er tætnet ved hjælp af en forbindelse dannet ved lim, klæbemiddel 10 eller et tilsvarende tætnende materiale. Når elementet, dvs. rørforbindelsen, kablet, osv., bliver indsat i den første og anden åbning tilvejebringes en tætning mod ydersiden af elementet ved hjælp af det tætnende organ i det pladeformede element, som strækker sig ind i den an-15 den åbning.The method according to the invention is thus characterized in that the plate-shaped element with the second through-opening is formed as a single unit, consisting of two plate-shaped elements between which a sealing member is mounted extending into the other opening, and wherein The element can be fixed, for example by gluing, on an existing surface of the above-mentioned module, ie. a ceiling, floor, wall, etc., with the second opening aligned with the first opening. The plate-shaped element is sealed by a compound formed by glue, adhesive 10 or a similar sealing material. When the element, i.e. the pipe connection, the cable, etc., being inserted into the first and second apertures, a seal is provided to the outside of the member by means of the sealing member of the plate-shaped member extending into the other aperture.

I en foretrukken udførselsform er det tætnende organ udformet således, at der også tilvejebringes en tætning når elementet (rørforbindelsen eller tilsvarende) vibrerer på 20 grund af opvarmning, afkøling, osv.In a preferred embodiment, the sealing member is formed such that a seal is also provided when the element (pipe connection or the like) vibrates due to heating, cooling, etc.

FordeleAdvantage

Baseret på den ovenfor beskrevne udformning opnås en kom-25 ponent, der let kan præfabrikeres og som består af ukritiske konstruktionselementer, som i dem selv repræsenterer gennemprøvet teknik med henblik på tætning og modstandsdygtighed overfor varme. De præfabrikerede komponenter er lette at lagre og håndtere. Komponenterne kan 30 indsættes i den aktuelle åbning i loft-, gulv- eller vægkonstruktionen særdeles let. Elementet, for eksempel rørledningen, kan udvide sig eller trække sig sammen, vibrere eller forskydes (i længderetningen), mens der opretholdes en høj grad af tætning.Based on the design described above, a component which is readily prefabricated and which consists of uncritical structural elements, which in themselves represent proven technique for sealing and heat resistance, is obtained. The prefabricated components are easy to store and handle. The components can be inserted very easily into the current opening in the ceiling, floor or wall structure. The element, for example, the pipeline, can expand or contract, vibrate or displace (longitudinally) while maintaining a high degree of sealing.

Udførlig beskrivelse af en fortrukken udførselsformDetailed description of a preferred embodiment

Figur 1 viser et pladeformet element 1 med en cirkulær 25 horisontal del. Den ydre diameter er indikeret med yd. Elementet har en gennemgående åbning 2, ind i hvilket en tætning 3 strækker sig. Tætningen har en åbning med en indvendig diameter id. Svarende til figur 2 er den for indeværende fortrukne udførselsform konstrueret af et 30 første og et andet pladeformet element 4 og 5 med tætningen 3 monteret mellem disse. Det indre eller første pladeformede element 4 har en ringformet indre overflade 4a, som danner en støtteflade med hvilken det pladeformede element 1 er i kontakt med et delvist vist modul 7, som 7 DK 173465 B1 omgiver rummet 6. Støttefladen 4a er derved i kontakt med en indre overflade 7a på modulet.Figure 1 shows a plate-shaped element 1 with a circular horizontal portion. The outer diameter is indicated by yd. The element has a through opening 2 into which a seal 3 extends. The seal has an opening with an inside diameter id. Similar to Figure 2, the presently preferred embodiment is constructed of a first and second plate-shaped members 4 and 5 with the seal 3 mounted therebetween. The inner or first plate-shaped element 4 has an annular inner surface 4a, which forms a support surface with which the plate-shaped element 1 is in contact with a partially shown module 7, which surrounds the space 6. The supporting surface 4a is in contact with it. an inner surface 7a of the module.

Det andet (ydre) pladeformede element 5 har dele 5a, som 5 strækker sig ud over det første (indre) element 4. På de ovenfor nævnte fremspringende dele, som har form som en ring, er der fastgørelses midler 8 som i udførselseksemplet består af dobbeltsidet klæbebånd. Tætningen 3 er forsynet med et fastgorelses-lag 9 på de dele, der støder 10 op mod det første og andet pladeformede element. Det ovenfor nævnte fastgørelses-lag kan bestå af lim, klæbemiddel eller tilsvarende. Det dobbeltsidede klæbebånd er fastgjort til indersiden på de ovenfor nævnte fremspringende dele 5a og danner fastgørelses-midlet for det pla-15 deformede element 1 mod overfladen 7a ved at den anden side af båndet klæber til væggen 7a. Omkring periferien af det andet pladeformede element er det pladeformede element 1 fæstet og tætnet med en fleksibel forbindelse af, for eksempel, silikone 10, som i det viste eksempel 20 også danner en tætning med båndet 8.The second (outer) plate-shaped member 5 has portions 5a which extend beyond the first (inner) member 4. On the aforementioned protruding parts, which are in the form of a ring, there are fasteners 8 which in the exemplary embodiment consist of double-sided adhesive tape. The seal 3 is provided with an attachment layer 9 on the portions 10 adjacent to the first and second plate-shaped members. The above-mentioned attachment layer may consist of glue, adhesive or the like. The double-sided adhesive tape is attached to the inside of the aforementioned projecting portions 5a and forms the fastener of the plate-shaped member 1 against the surface 7a by the other side of the tape adhering to the wall 7a. Around the periphery of the second plate-shaped element, the plate-shaped element 1 is attached and sealed with a flexible connection of, for example, silicone 10, which in the example 20 shown also forms a seal with the band 8.

Modulet 7 har en åbning 11 og det pladeformede element 1 er fastgjort på væggen 7a således at åbningerne 2 og 11 er rettet ind efter hinanden (centreret i forhold til 25 hinanden). Et element, for eksempel en rørledning 12, er indsat i åbningerne. Diameteren eller det ydre mål D på elementet er i dette tilfælde større end tætningens diameter id, hvilket betyder, at tætningen kan folde og danne en tætning med ydersiden eller den ydre overflade 30 (overfladen på en indkapsling) 12a af elementet 12. I det viste eksempel overgår denne diameter diameteren id med omtrent 4 mm eller med en størrelse, som er tilpasset i hvert enkelt tilfælde ved valg af en id i forhold til D.The module 7 has an opening 11 and the plate-shaped element 1 is fixed to the wall 7a so that the openings 2 and 11 are aligned one after the other (centered relative to each other). An element, for example a pipeline 12, is inserted into the openings. In this case, the diameter or outer dimension D of the element is larger than the diameter id of the seal, which means that the seal can fold and form a seal with the outer or outer surface 30 (the surface of an enclosure) 12a of the element 12. for example, this diameter exceeds the diameter id by about 4 mm or by a size adapted in each case by selecting an id relative to D.

Det pladeformede element har en ringe højde a ud fra den 35 indre overflade 7a.The plate-shaped element has a slight height a from the inner surface 7a.

8 DK 173465 B1 I en foretrukken udførselsform kan yd vælges til at være mellem 20 og 500 mm og id kan vælges til at være mellem 3 og 470 mm. Gulvet, loftet, væggen, osv. kan udføres af konventionelle materialer, fliser, gips, beton, metalpla-5 de, osv. Det indre pladeformede element eller basisplade kan have en tykkelse mellem 0,5 mm og 2,0 mm. Det andet pladeformede element eller frontpladen kan have en tilsvarende tykkelse. Det tætnende element kan have en tykkelse mellem 0,5 mm og 3,0 mm. Det dobbeltsidede klæbe-10 band, som kan udføres på en kendt måde kan have en tykkelse pa 0,2 mm til 5,0 mm. Front- og basispladen kan fremstilles af rustfrit stål {SIS 2333 eller 2334) eller tilsvarende. Alternativt kan pladerne fremstilles af emaljeret metalplade eller et polymert materiale (for ek-15 sempel polyamid eller PVDF = polyvinyldifluorid) osv. Den tætnende membran eller tætningen består af gummi eller elastomert materiale, for eksempel silikone eller EPDM.In a preferred embodiment, yd may be selected to be between 20 and 500 mm and id may be selected to be between 3 and 470 mm. The floor, ceiling, wall, etc. can be made of conventional materials, tiles, plaster, concrete, metal plate, etc. The inner plate-shaped element or base plate can have a thickness between 0.5 mm and 2.0 mm. The second plate-shaped element or the front plate may have a corresponding thickness. The sealing member may have a thickness between 0.5 mm and 3.0 mm. The double-sided adhesive tape, which can be made in a known manner, may have a thickness of 0.2 mm to 5.0 mm. The front and base plate can be made of stainless steel (SIS 2333 or 2334) or similar. Alternatively, the sheets can be made of enamelled metal sheet or polymeric material (for example polyamide or PVDF = polyvinyl difluoride) etc. The sealing membrane or seal is made of rubber or elastomeric material, for example silicone or EPDM.

Ved hjælp af ovenstående, forhindres lækage fra det omgi-20 vende rum 13 ind i rummet 6. Uønskede partikler, gasser og forurenende substanser forhindres derved i at trænge ind i rummet 6, som yderligere kan sættes under tryk i forhold til omgivelserne 13. Kun elementet 12’s indre 12b er i forbindelse med rummet 6 og en (ikke vist) kilde for 25 et medium, et andet rum, osv. Forskellige media kan således bringes ind i og/eller fjernes fra rummet 6 via elementets indre 12b uden fare for at uønskede forurenende substanser trænger ind.By means of the above, leakage from the surrounding compartment 13 is prevented into the compartment 6. Unwanted particles, gases and pollutants are thereby prevented from entering the compartment 6, which can be further pressurized in relation to the surroundings 13. Only the interior 12b of the element 12 is in connection with the space 6 and a (not shown) source for a medium, another space, etc. Various media can thus be brought into and / or removed from the room 6 via the interior 12b of the element without danger of unwanted pollutants penetrate.

30 I følge figurerne 3 og 4 vises horisontale fremstillinger af det pladeformede element 1’ og 1'1 med åbninger 2' og 2''. Det følger heraf, at det pladeformede element er udført med kvadratiske eller rektangulære ydre dimensioner.According to Figures 3 and 4, horizontal representations of the plate-shaped elements 1 'and 1'1 with apertures 2' and 2 '' are shown. It follows that the plate-shaped element is made of square or rectangular outer dimensions.

I figur 3 er målene for bredden og højden indikeret med 35 henholdsvis b go h. Åbningen 2’ kan være kvadratisk eller 9 DK 173465 B1 rektangulær. Udover de viste kombinationer er mange andre mulige.In Figure 3, the dimensions of the width and height are indicated by 35 and b go h, respectively. The opening 2 'may be square or rectangular. In addition to the combinations shown, many others are possible.

I figur 4 er målene for bredde og højde indikeret med 5 henholdsvis b' og h'. For en given udførselsform kan bredden være 30 mm - 1200 mm og højden 30 mm - 470 mm.In Figure 4, the width and height measures are indicated by 5 b 'and h' respectively. For a given embodiment, the width may be 30 mm - 1200 mm and the height 30 mm - 470 mm.

Det indre mal im kan være 3 mm - 470 mm.The inner mold can be 3 mm - 470 mm.

Det pladeformede element er fæstnet på den indre overfla-10 de 7a på modulet 7 således at åbningerne i modulet og i det pladeformede element er centrerede. Den fleksible forbindelse eller den tætnende forbindelse 10 eller tilsvarende er anbragt omkring periferien af det pladeformede element. Derefter indsættes elementet 12 i åbningen.The plate-shaped element is attached to the inner surface 7a of the module 7 so that the openings in the module and in the plate-shaped element are centered. The flexible or sealing compound 10 or the like is arranged around the periphery of the plate-shaped element. The element 12 is then inserted into the opening.

15 Elementet 12 centreres i åbningen således at en god tætning sikres mod tætningsorganet 3.The element 12 is centered in the opening so that a good seal is secured against the sealing member 3.

Tætningen er udført til at kunne modstå en temperatur på 145 °C i to timer, også i tilfælde af direkte kontakt.The seal is designed to withstand a temperature of 145 ° C for two hours, even in the case of direct contact.

20 Anordningen bevirker kun ringe varmetransmission på grund af brugen af gummi og rustfrit stål for de ydre plader, som derved fungerer som køleflanger. Anordningen danner en enhed, som kan installeres på simpel vis uden at interferere med kravene til det rene rum og også uden brug 25 af værktøj eller andet eksternt udstyr. Der er således ikke behov for yderligere fastgørelse forbundet med for eksempel boring eller fastgørelse med skruer, osv., som medfører en princip-betinget risiko for at forurene. Tætningen tillader bevægelse i aksial og radial retning og 30 også i en vinkel i forhold til elementet (rørledningen eller tilsvarende), uden at de tætnende egenskaber går tabt. Tætningen er foldet som en krave omkring rørledningen eller tilsvarende. Opfindelsen er ikke begrænset til den fortrukne udførselsforra i følge det ovenstående, men 10 DK 173465 B1 kan modificeres indenfor rammerne af de efterfølgende krav og opfindelsens koncept.The device only causes poor heat transmission due to the use of rubber and stainless steel for the outer plates, which thereby act as cooling flanges. The device forms a unit which can be installed in a simple manner without interfering with the requirements of the clean room and also without the use of tools or other external equipment. Thus, there is no need for additional fastening associated with, for example, drilling or fastening with screws, etc., which entails a principled risk of contamination. The seal allows movement in the axial and radial directions and also at an angle to the element (the pipeline or equivalent) without losing the sealing properties.
