Abstract
Description
508 993 2 peratur. På detta sätt åstadkommes som lätt inses för det första ett ljudhinder genom väggen även om inte brandskyddsskummet slu- ter absolut tätt till ledningarna. Dessutom försvåras brandsprid- ningen genom väggen, för det första genom den ökade längd som en eventuell brand måste sprida sig över men dessutom genom att brandskyddsmassan vid.brand och förhöjd.temperatur expanderar och utvidgar sig mot huvens mynning och med samtidigt utfyllande av den eventuella kvarvarande fria tvärsnittsarean i huven så att fullständig täthet erhålles. 508 993 2 peratur. In this way, as can be easily seen, a sound barrier is created through the wall, even if the fire protection foam does not adhere absolutely tightly to the pipes. In addition, the spread of fire through the wall is made more difficult, firstly by the increased length that a possible fire must spread over, but also by the fire protection compound at fire and elevated temperature expanding and expanding towards the mouth of the hood and at the same time filling in any remaining free cross-sectional area in the hood so that complete tightness is obtained.
Den expanderande brandskyddsmassan fungerar på så sätt att vid förhöjd temperatur expanderar och kan därigenom täta till eventuella öppningar eller passager runt eller mellan kablarna.The expanding fire protection compound works in such a way that at elevated temperature it expands and can thereby seal to any openings or passages around or between the cables.
För att ytterligare förhindra ljud och lufttransport från rum till rum redan när förhöjd temperatur ej föreligger kan när- mast kablarna ett tätande ljudabsorberande skummaterial vara an- ordnat som sedan vid en eventuell brand vare sig det smälter el- ler inte av den expanderande brandtätningen komprimeras eller pressas undan så att branden ej kan spridas sig denna väg. Även om det i dagens läge bedöms som mest lämpligt att pla- cera slingan eller böjen på kablar eller ledningar uppåt så kan man i stället tänka sig att placera den vågrätt exempelvis i fal- let med ledningskanaler, vilket kan underlätta integrerandet i kanalerna. Ledningarna behöver inte vara elektriska utan kan även innefatta gas eller vattenledningar liksom ljusledare.In order to further prevent noise and air transport from room to room even when elevated temperature is not present, a sealing sound-absorbing foam material can be arranged closest to the cables, which is then compressed in the event of a fire, whether it melts or not by the expanding fire seal pressed away so that the fire cannot spread this way. Although in the current situation it is considered most appropriate to place the loop or bend on cables or wires upwards, it is instead conceivable to place it horizontally, for example in the case of cable ducts, which can facilitate integration in the ducts. The cables do not have to be electrical but can also include gas or water pipes as well as light guides.
Uppfinningen skall nedan beskrivas närmare i anslutning till ett på bifogad ritning visat utföringsexempel. Härvid visar fig ; ett tvärsnitt genom en brandskyddsgenomföring i enlighet med uppfinningen och fig 2 en detalj härav.The invention will be described in more detail below in connection with an exemplary embodiment shown in the accompanying drawing. In this case, FIG. a cross section through a fire protection bushing in accordance with the invention and Fig. 2 a detail thereof.
Den i fig 1 visade brandskyddsanordningen innefattar två hu- var 1, en pà varje sida om en vägg 2. I väggen 2 är ett genomfö- ringshàl 3 anordnat. Huvarna 1 är pá insidan infodrade med vid värmeförhöjning expanderande brandtätningsmaterial 4 så att en kanal 6 bildas från huvarnas 1 nedåt vända öppningar 5 upp till väggöppningen. Även i väggöppningen kan expanderande brandtät- ningsmaterial anbringas exempelvis rörformat runt kablarna.The fire protection device shown in Fig. 1 comprises two hoods 1, one on each side of a wall 2. In the wall 2 a lead-through hole 3 is arranged. The hoods 1 are lined on the inside with fire-sealing material 4 which expands during the increase in heat so that a channel 6 is formed from the downwardly facing openings 5 of the hoods 1 up to the wall opening. Also in the wall opening, expanding fire sealing material can be applied, for example, tubularly around the cables.
Om så önskas kan kanalerna 6 i det expanderande brandtät- ningmaterialet 4 i sin tur vara infodrade med lämpligt skummate- 508 995 3 rial för att ytterligare säkerställa ljud och lufttätning i nor- malfallet.If desired, the ducts 6 in the expanding fire sealing material 4 can in turn be lined with suitable foam material to further ensure sound and air sealing in the normal case.
Vid en eventuellt inträffande brand stiger temperaturen i det rum där branden föreligger sà att brandtätningsmaterialet expanderar och pressas mot kablarna, Om kablar behöver bytas ut eller tilläggas skruvas helt en- kelt huvarna bort från väggen och genomföringen är nu fritt till- gänglig, för att äter förslutas med huvarna när erforderliga ar- beten utförts.In the event of a fire, the temperature in the room where the fire is located rises so that the fire sealing material expands and is pressed against the cables. If cables need to be replaced or added, the hoods are simply screwed away from the wall and the bushing is now freely accessible to closed with the hoods when the required work has been performed.
Brandtätningsanordningen i enlighet med uppfinningen kan även utgöras av en kassett som anordnas i väggen eller i en led- ningskanal.The fire sealing device in accordance with the invention can also consist of a cassette which is arranged in the wall or in a conduit.
I stället för plàt i huvarna kan andra temperaturhärdiga material användas, t ex gips.Instead of sheet metal in the hoods, other temperature-resistant materials can be used, such as plaster.
