Description
Foreliggende oppfinnelse angår en gjennomføring for i det minste en ledning, så som rør, kabel eller lignende gjennom en veggåpnlng, med minst to tetningslegemer som ved begge veggsidene tetter mot ledningen og mot hullveggene og med et i hulrommet mellom tetnlngslegemene, hullveggen og ledningen anbragt flammebeskyttelsesmiddel. The present invention relates to a passage for at least one line, such as a pipe, cable or the like through a wall opening, with at least two sealing bodies that on both wall sides seal against the line and against the hole walls and with a flame protection agent placed in the cavity between the sealing bodies, the hole wall and the line .
Gjennomføring av denne art er kjent fra DE-GM 2328014 der det imidlertid ikke er noen henvisning til flammebeskyttelses-midlets beskaffenhet, og tjener til å danne en brann-beskyttelsesavslutning ved hjelp av hvilken ledningsgater kan avtettes brannsikkert gjennom en vegg mellom to atskilte brannavsnittssoner. Foruten en lengst mulig brannmotstandstid skal gjennomføringen dessuten ha best mulige egenskaper for avtetting mot vann, gass og røk. Implementation of this kind is known from DE-GM 2328014 where, however, there is no reference to the nature of the flame retardant, and serves to form a fire protection closure with the help of which conduits can be sealed fireproof through a wall between two separate fire section zones. In addition to the longest possible fire resistance time, the installation must also have the best possible properties for sealing against water, gas and smoke.
Fra DE-OS 2947593 er det kjent en gjennomføring med en annen oppbygging der det benyttes fast fyllstoff for isolasjon mot brann. Dette fyllstoffet består av en brannbeskyttelsesmasse som utvider seg ved varmepåvirkning og inneholder en gassdanner som utvikler gass ved en bestemt temperatur og som da strømmer ut fra massen. Hensikten er 1 det minste delvis å fylle det tomrom som oppstår ved avbrenning og derved forhindre en rask utvikling av brannsonen. From DE-OS 2947593, an implementation with a different structure is known in which solid filler is used for insulation against fire. This filler consists of a fire protection mass that expands when exposed to heat and contains a gas generator that develops gas at a certain temperature and which then flows out of the mass. The purpose is to at least partially fill the void that occurs during burning and thereby prevent a rapid development of the fire zone.
Fra DE—OS 2737978 er det kjent ved brannhemmende gjennom-føringer å bruke brannbeskyttelsesmasser som består av en polyolefin med mineralfyllstoff, idet minerallfyllstoffet består av talg, aluminiumhydroksyd, kalsiumkarbonat eller glimmer eller en blanding av disse stoffene. Aluminiumhydroksyd oppløses ved oppvarming i tilfelle brann under betydelige varmeopptak og avspalter vann som frigis damp-formet. Varmeopptaket virker da som nedkjøling av ledningen og gjennomføringsdelene i brannsonen, og vannet virker som en flammehemmende beskyttelsesgass da det fortrenger surstoffet ved brannstedet. Imidlertid er tilsetting av et slikt flammebeskyttelsesmiddel til plast begrenset til forholdsvis små mengder, da innblandingen har en sterk innflytelse på plastblandingens tekniske verdier. Fra den sistnevnte publikasjonen er det likeledes kjent til brannbeskyttelses-massen å tilsette et esemiddel som eser ved oppvarmingen fra en brann. From DE-OS 2737978 it is known for fire-retardant penetrations to use fire protection compounds consisting of a polyolefin with mineral filler, the mineral filler consisting of tallow, aluminum hydroxide, calcium carbonate or mica or a mixture of these substances. Aluminum hydroxide dissolves when heated in the event of a fire during significant heat absorption and splits off water which is released in the form of steam. The heat absorption then acts as a cooling of the line and the pass-through parts in the fire zone, and the water acts as a flame-retardant protective gas as it displaces the oxygen at the fire site. However, the addition of such a flame retardant to plastics is limited to relatively small quantities, as the mixture has a strong influence on the technical values of the plastic mixture. From the latter publication, it is also known to add an effervescent agent to the fire protection mass which effervesces when heated by a fire.
Fra DE-OS 2529911 er det kjent en luftkanal der det som brannbeskyttelsessperre er anordnet brannbeskyttelsesplater i avstand fra hverandre og som løper parallelt med strømnings-retningen. Disse brannbeskyttelsesplatene inneholder et ved oppvarming skumbart stoff, nemlig vannholdlg natriumsilikat der vannet tjener som drivmiddel ved oppvarming. For å beskytte det vannholdige natriumsilikatet fra skadelige ytre innflytelser, er brannbeskyttelsesplatene anbragt i en metallfoliepose. From DE-OS 2529911, an air duct is known in which, as a fire protection barrier, fire protection plates are arranged at a distance from each other and which run parallel to the direction of flow. These fire protection boards contain a substance that foams when heated, namely hydrous sodium silicate where the water serves as a propellant when heated. To protect the hydrous sodium silicate from harmful external influences, the fire protection plates are placed in a metal foil bag.
Foreliggende oppfinnelse går ut på å utforme en gjennomføring av den innledningsvis nevnte art slik at mengden av dette brannbeskyttelsesmiddelet er størst mulig og derved også oppnå størst mulig varighet på flammemotstanden i gjennom-føringen, og at gjennomføringen enkelt og raskt kan forsynes med dette flammebeskyttelsesmiddelet. Dette oppnås ifølge oppfinnelsen ved at flammebeskyttelsesmidlet som ved oppvarming ved brann, oppløses under opptaket av varme og frembringer en flammehemmende beskyttelsesgass, foreligger som et kornet til støvformet fast stoff som er fylt i i forhold til hulrommets dimensjoner små pakningsenheter, og at hulrommet er fullpakket med disse paknlngsenhetene. The present invention is to design a penetration of the type mentioned at the outset so that the quantity of this fire protection agent is the greatest possible and thereby also achieve the greatest possible duration of the flame resistance in the penetration, and that the penetration can be easily and quickly supplied with this flame protection agent. According to the invention, this is achieved by the fact that the flame protection agent, as when heated in a fire, dissolves during the absorption of heat and produces a flame-retardant protective gas, is present as a granular to dust-shaped solid substance that is filled in packing units that are small in relation to the dimensions of the cavity, and that the cavity is packed with these the packaging units.
Bruk av flammebeskyttelsesmiddel i små pakningsenheter muliggjør en god ifylling av gjennomføringen med flammebeskyttelsesmiddel, det vil si en høyt konsentrert, praktisk talt kompakt og fullstendig hulromsfri fylling av flammebeskyttelsesmlddelet. The use of flame retardant in small packing units enables a good filling of the penetration with flame retardant, i.e. a highly concentrated, practically compact and completely void-free filling of the flame retardant part.
I en foretrukket utførelsesform er den ytre omhyllingen av pakningsenhetene dannet av fleksible poser, puter eller lignende og består av 1 seg selv lite oppflairmende materiale. In a preferred embodiment, the outer casing of the packing units is formed from flexible bags, cushions or the like and consists of a material that does not in itself flare.
Oppfinnelsen skal i det følgende forklares nærmere under henvisning til tegningen, som viser et utførelseseksempel for oppfinnelsen. Den eneste figuren viser en gjennomføring Ifølge oppfinnelsen 1 akslalsnltt 1 innbygd tilstand 1 en vegg. In the following, the invention will be explained in more detail with reference to the drawing, which shows an embodiment of the invention. The only figure shows an implementation According to the invention 1 akslalsnltt 1 built-in state 1 a wall.
På tegningen er ledningen 1, f.eks. en kabel med ikke viste enkeltledninger, ført gjennom en åpning 2 i en betongvegg 3. Veggåpnlngen 2 er ved begge veggsider avsluttet ved hjelp av to elastiske tetningslegemer 4 av gummi eller lignende elastisk formbart materiale, som ligger tett an mot ledningen 1 og mot et fSringsrør 12, som danner åpningens 2 mantel 13. I veggen 3 er det på begge sider innstøpt en endeplate 6. Dessuten er det i hvert tetningslegeme 4 anordnet en pressinnretning som presser tetningslegemene elastisk mot veggåpningene, hvilken pressinnretning i dette tilfelle er en pressring 7. I tillegg har i utførelseseksempelet hvert tetningslegeme 4 et utover åpent ringspor 8, som omgir ledningen 1 sirkelformet og hvis aksielle utstrekning er så dyp at det rekker utover det området i hvilket tetningslegemet 4 skal avtette ledningen 1 respektiv mantelen 13. I dette ringsporet 8 er pressringen 7 aksielt inntrykket. Veggtykkelsen på ringen 7 er større enn bredden på det udeformerte ringsporet 8 ved ikke spent tetningslegeme. Pressringen 7 bevirker ved inntrykking i ringsporet 9 en materialfortrengelse i tetningslegemet 4 med det resultat at tetningslegemet 4 legger seg an med større trykk mot ledningen 1 og mot mantelen 13 jo dypere pressringen føres inn i ringsporet 8. Derved oppnås den på tegningen viste mulighet, nemlig at veggtykkelsen på pressringen 7, sett 1 akslalsnltt utvider seg kileformet utover fra den i inn-stikningsretningen fremre ringenden, ved som vist i ut-førelseseksempelet oppstår en kileformet utvidelse både av den indre og den ytre ringflaten, slik at akslalprofilen av pressringen får form av en dobbeltklle. Dessuten har pressringen både ved ytterflaten og innerflaten en i omkretsretnlngen forløpende ri11Ing 9, som er utformet som en gjenge ved hjelp av hvilken pressringen kan skrus inn 1 tetnlngslegemets 4 ringspor 8. Denne rillingen 9 respektiv denne gjengen fører først og fremst til en formsluttende forbindelse av pressringen i tetningslégemet 4 og letter dessuten montasjen av pressringen 7, da det for denne monteringen bare er nødvendig med en dreiende bevegelse av pressringen. For å lette dreiningen av pressringen 7 er det på den ut av ringsporet 8 utstikkende enden av pressringen 7 anordnet en fortykkelse 10 som kan være forsynt med hull 11, som kan benyttes til opptagelse av nøkkeltapper på en egnet nøkkel. I hulrommet mellom tetningslegemene 4, mantelen 13 og ledningen 1 er det innført et flammebeskyttelsesmiddel 14 som utfyller hulrommet og som ved oppvarming i branntilfelle oppløses under varmeopptak og avgir en flammehemmende beskyttelsesgass. Flammebeskyttelsesmlddelet 14 inneholder overveiende aluminiumhydroksyd og en tilsetning av et esemiddel som eser på grunn av varmen i et branntilfelle. Flammebeskyttelsesmlddelet har form av et kornet til støvformet faststoff og er fylt i forhold til dimensjonen på hulrommet små, formbare pakningsenheter 14 ved hjelp av hvilke hulrommet fullpakkes og tilstoppes. Den ytre om-hyll Ingen på disse pakningsenhetene 14 består av fleksible poser, puter eller lignende, og kan være fremstilt av lite flammebart materiale-. In the drawing, the wire is 1, e.g. a cable with individual wires not shown, led through an opening 2 in a concrete wall 3. The wall opening 2 is closed on both sides of the wall by means of two elastic sealing bodies 4 made of rubber or similar elastically malleable material, which lie close to the wire 1 and to a spring pipe 12, which forms the mantle 13 of the opening 2. An end plate 6 is embedded in the wall 3 on both sides. In addition, each sealing body 4 is provided with a pressing device which presses the sealing bodies elastically against the wall openings, which pressing device in this case is a pressing ring 7. in addition, in the design example, each sealing body 4 has an outwardly open ring groove 8, which surrounds the wire 1 in a circular shape and whose axial extent is so deep that it extends beyond the area in which the sealing body 4 is to seal the wire 1 or the jacket 13. In this ring groove 8, the compression ring 7 axial impression. The wall thickness of the ring 7 is greater than the width of the undeformed ring groove 8 when the sealing body is not tensioned. The pressing ring 7, when pressed into the annular groove 9, causes material displacement in the sealing body 4 with the result that the sealing body 4 applies greater pressure against the line 1 and against the jacket 13 the deeper the pressing ring is inserted into the annular groove 8. The possibility shown in the drawing is thereby achieved, namely that the wall thickness of the press ring 7, set 1 axially expands wedge-shaped outwards from the front ring end in the insertion direction, whereby, as shown in the design example, a wedge-shaped expansion of both the inner and outer ring surface occurs, so that the axial profile of the press ring takes the form of a double cloth. In addition, the pressing ring has both on the outer surface and the inner surface a groove 9 running in the circumferential direction, which is designed as a thread by means of which the pressing ring can be screwed into the ring groove 8 of the sealing body 4. This groove 9 respectively this thread primarily leads to a form-locking connection of the pressing ring in the sealing body 4 and also facilitates the assembly of the pressing ring 7, as for this assembly only a rotating movement of the pressing ring is necessary. To facilitate the turning of the pressing ring 7, a thickening 10 is arranged on the end of the pressing ring 7 protruding from the ring groove 8, which can be provided with a hole 11, which can be used to receive key pins on a suitable key. In the cavity between the sealing bodies 4, the sheath 13 and the wire 1, a flame retardant 14 has been introduced which fills the cavity and which, when heated in the event of a fire, dissolves during heat absorption and emits a flame retardant protective gas. The flame protection material 14 contains predominantly aluminum hydroxide and an addition of an effervescent agent which effervesces due to the heat in the event of a fire. The flame protection material has the form of a granular to dust-shaped solid and is filled in relation to the dimension of the cavity with small, malleable packing units 14 with the help of which the cavity is fully packed and plugged. The outer shelf none of these packing units 14 consists of flexible bags, cushions or the like, and can be made of low-flammability material.
