Description
Den forelippende oppfinnelse vedrører en brannhemmende rør-forinp med et fyllmateriale for pjennomførinp av en plastrørledning gjennom en vepp i et bypp. The pending invention relates to a fire-retardant pipe liner with a filling material for the smooth passage of a plastic pipeline through a gap in a gap.
Plastrørledninper som ofte anvendes i bypninper for tiden har den ulempe at de i tilfelle brann smelter eller brenner mepet hurtig. Derved består opså fare for at røkpass op ild kan komme inn i nabo-rom gjennom de frie åpninper etter ødeleppelsen av rørledningene. Plastic pipe fittings which are often used in urban fittings at present have the disadvantage that in the event of a fire they melt or burn very quickly. There is also a risk that smoke and fire can enter neighboring rooms through the free openings after the destruction of the pipelines.
Formålet med den forelippende onpfinnelse er å frembringe en brannhemmende rørforinp som i tilfelle ødeleppelse av en plastrør-ledning ved brann i et rom lukker ånninpen i veppen til tilstøtende rom automatisk op derved hindrer eller forsinker inntrenpningen av røkpass op ild i disse rom. The purpose of the preceding invention is to produce a fire-retardant pipe fitting which, in the event of a plastic pipe being damaged by fire in a room, automatically closes the vent in the vent to the adjacent room, thereby preventing or delaying the penetration of smoke and fire into these rooms.
Dette formål opnnås ifølge oppfinnelsen ved at fyllmaterialet This purpose is achieved according to the invention by the filling material
i rørforingen består av et materiale som ved temperaturer over 150°C in the pipe lining consists of a material which at temperatures above 150°C
eser opp til flere ganger sitt opprinnelige volum. expands to several times its original volume.
Det er riktignok kjent rørforinger for gjennomføring av rør-ledninger. Ved en utførelsesform ifølge tysk patentskrift 1.198.624 består rørforingen av plast og rørledningen av metall. Rørforingen har i dette tilfelle over en del av sin lengde et fyllmateriale av ildfast materiale, for eksempel asbestfibre eller glassull, for å hindre at rørforingen blir helt ødelagt i tilfelle brann. Formålet er følgelig ikke i dette tilfelle å lukke en åpning i tilfelle brann, men man prøver bare å oppnå å holde et lukket rom, dvs. det ring-formete rom mellom rørledning og rørforing, lukket ved ildinnvirkning. It is true that pipe linings are known for the passage of pipelines. In an embodiment according to German patent document 1,198,624, the pipe lining consists of plastic and the pipeline of metal. In this case, the pipe lining has, over part of its length, a filling material of refractory material, for example asbestos fibers or glass wool, to prevent the pipe lining from being completely destroyed in the event of a fire. The purpose is therefore not in this case to close an opening in the event of fire, but one only tries to achieve keeping a closed space, i.e. the ring-shaped space between the pipeline and the pipe lining, closed in the event of fire.
Oppfinnelsen vil bli nærmere forklart i den etterfølgende beskrivelse, hvor to utførelseseksempler av foringen ifølge oppfinnelsen er angitt, under henvisning til de medfølgende tegninger, hvori: Fig. 1 viser et lengdesnitt gjennom en gjennomføring av en plastledning for eksempel gjennom en mur. Fig. 2 viser et tilsvarende lengdesnitt gjennom en annen ut-førelsesform av føringen. The invention will be explained in more detail in the following description, where two design examples of the liner according to the invention are indicated, with reference to the accompanying drawings, in which: Fig. 1 shows a longitudinal section through a passage of a plastic cable, for example through a wall. Fig. 2 shows a corresponding longitudinal section through another embodiment of the guide.
En plastrørledning 2 ifølge fig. 1 løper gjennom en boring i A plastic pipeline 2 according to fig. 1 runs through a bore i
en mur 1. I murens 1 område er ledningen 2 omgitt av en rørforing 3 i form av et sylindrisk blikkhus 4 som i gavlene fortrinnsvis er lukket og som omfatter et fyllmateriale 5- Dette består av et materiale som har den egenskap at det ved oppvarming til temperaturer på over omtrent 150°C eser opp og utvides til flere ganger sitt opprinnelige volum. Et slikt materiale for dette formål er for eksempel vannholdig natriumsilikat som kan være forsynt med organ-iske tilsetninger. a wall 1. In the area of the wall 1, the line 2 is surrounded by a pipe lining 3 in the form of a cylindrical tin housing 4 which is preferably closed at the ends and which includes a filling material 5- This consists of a material which has the property that when heated to temperatures above approximately 150°C rise and expand to several times their original volume. Such a material for this purpose is, for example, aqueous sodium silicate which can be provided with organic additives.
I tilfelle det bryter ut brann i rommet på den ene side av muren 1 går rørledningen 2 først over i plastisk tilstand og for-brenner deretter. Inne i blikkhuset 4 vil fyllmaterialet 5 ese opp og presse den rørdel som befinner seg i huset 4 og som på grunn av oppvarmingen også vil være plastisk, fullstendig sammen, slik at gjennomgangsåpningen lukkes. En del av det oppesete materiale blir derved selvfølgelig trengt utad gjennom den nå frie endeåpning. Imidlertid frembringes det langs blikkhuset mot dettes kaldere side stadig nytt skumstoff, slik at den romlukkende virkning opprettholdes i lengre tid og det oppnås en lang brannmotstandsvarighet. In the event that a fire breaks out in the room on one side of the wall 1, the pipeline 2 first goes into a plastic state and then burns. Inside the tin housing 4, the filling material 5 will rise and press the pipe part which is located in the housing 4 and which, due to the heating, will also be plastic, completely together, so that the passage opening is closed. A part of the stuck-up material is thereby of course forced outwards through the now free end opening. However, new foam material is constantly produced along the tin housing towards its colder side, so that the room-sealing effect is maintained for a longer time and a long fire resistance duration is achieved.
Huset H kan være utformet av ett blikkstykke. Det vil imidlertid kunne være fremstilt av en sylindrisk kappedel og to separate endedeler som er festet på denne. Rørforingen vil som antydet med strekpunkterte linjer kunne rage frem på begge sider av muren 1. The housing H can be designed from one piece of tin. However, it could be made of a cylindrical casing part and two separate end parts which are attached to this. As indicated by the dotted lines, the pipe liner will be able to protrude on both sides of the wall 1.
Som vist i fig. 2 kan rørforingen 3 løpe gjennom bare en del As shown in fig. 2, the pipe lining 3 can run through only a part
av muren 1 (eller et tak).. Det har ved forsøk vist seg at tykkelsen på materialet 5 med fordel bør være omtrent 1/5 av rørdiameteren. of the wall 1 (or a roof).. Experiments have shown that the thickness of the material 5 should preferably be approximately 1/5 of the pipe diameter.
