CLASS 21 c: 10/0 INT. CLASS H 01 b PATENT PERIOD FROM THE MON (1957 PROVIDED ON THE 17TH OF MAY) 1961 PUBLISHED ON 18 JULY 1961 Ans. 4635/1957 den 15/5 1957Horfil1 en riffling N A J BRATTBERG, KARLSKRONA Fire protection passage for one through a cradle for pipe The present invention relates to a fire protection passage for through a cradle for pipe. Then one by one. If the cradle passing the pipe is exposed to fire at the passage stall and the pipe is not exposed to fire-resistant material, the pipe will burn and / or melt down, whereby an opening is left in the cradle, through which a flame can be seen, so that the fire can spread. This is a malfunction, especially when the line is pressed through a fireproof cradle. The above-mentioned inconvenience is avoided by the invention in that the pipe passes through an opening in the cradle with a larger cross-section than the pipe, the space between the pipe and the cradles of the opening being filled with a filling material which increases its volume at increased temperature, so that fire-enlarged pipe part is replaced. of expanded filling material.
Vid de i svenska patentet 144 888 och 152 815 beskrivna anordningarna for att astadkomma tryckfata genomgangar fOr ledningar genom en trycktat vagg, anvandas Otininstone delvis elastiska passbitar for utfyllning mellan ledningarna oak en i vaggen anbragt ram. Enligt en utforingsform av foreliggande uppfinning utforas namnda elastiska passbitar av material som iikar sin volym vid uppvarmning. Sadant material 'av tillracklig brandsakerhet kan erhallas genom att ett gummimaterial blandas med brandsakert tillsatsmaterial med Adana egenskaper, att den gas sam materialet utvecklar vid uppvarmning tillsammans med materialet bildar en pang, brandhardig massa, som genom de uppkommande gasblasorna efter hand akar den ursprungliga materialvolymen runt kablarna. Massan maste vara av sadan konsistens och hallfasthet, att den tal de pakanningar, som kan uppkomma vid en brand, .sfisom forekommande drag, slackning med vatten, skum etc. Utgores ledningarna av kablar med traditionellt forekommande brannbar isolering, tatar utfyllningsmaterialet utrymmet for detta efter hand som isoleringen forbrinner. In the devices described in Swedish patents 144,888 and 152,815 for providing pressurized passages for pipes through a printed cradle, Otininstone partially elastic fitting pieces are used for filling between the pipes and a frame arranged in the cradle. According to an embodiment of the present invention, said elastic fitting pieces are made of material which equalizes its volume when heated. Such a material of sufficient fire safety can be obtained by mixing a rubber material with fireproof additive material with Adana properties, that the gas which the material develops when heated together with the material forms a pang, refractory mass which through the emerging gas bubbles gradually increases the original material volume around the cables. The mass must be of such consistency and firmness that the number of packings that can occur in the event of a fire, such as drafts, slackening with water, foam, etc. If the wires are made of cables with traditionally occurring flammable insulation, the filling material takes up space for this. hand that the insulation burns.
Aro ledningarna av smaltbar metall gar 10- gan in i oppningen efter den utsmalta metallen, men tatar denna, sa snart oppningens vaggar borjat att paverkas av varmen. Genom&igen kan gOras ytterligare brandsaker, genom att utfyllningsmaterialet gives en sadan sammanSattning, att den brannbara gas, som gummit utvecklar tillsammans med en kvavande gas Iran det &riga utfyllningsmaterialet astadkommer en gasblandning, som icke Or brannbar, nar materialet uppvfirmes. The pipes of fusible metal go into the opening after the molten metal, but take it as soon as the cradles of the opening have begun to be affected by the heat. Through & again, additional combustibles can be made by giving the filler material such a composition that the combustible gas which the rubber develops together with a suffocating gas in the other filler material produces a gas mixture which is not flammable when the material is heated.
Ett par utforingsformer •av uppfinningen beskrivas nedan i samband med atfoljande ritning, pa vilken fig. 1 visar en ledningsgenomgang enligt uppfinningen i gcnomskarning och fig. 2 visar 'sedd Iran vaggsidan en vy av en ledningsgenomgang, varvid passbitar anvandas for trycktat genomgang. A pair of embodiments of the invention are described below in connection with the following drawing, in which Fig. 1 shows a conduit passage according to the invention in cross-section and Fig. 2 shows, seen from the rock side, a view of a conduit passage, using fitting pieces for printed passage.
Vid den i fig. 1 visade utforingsformen Or en ledning 1 ford genom ett hal i en vagg 2, varvid halet liar storre tvarsektion An ledningen 1. Mellanrummet mellan ledningen 1 och halets sidovaggar Or utfyllt ,av ett fyllningsmaterial 3, som hat den egenskapen, att det vid brand akar sin volym ph ett sadant sfitt, att det fyller den del av ledningsarean, som forintas eller smatter ned av branden. In the embodiment Or shown in Fig. 1, a conduit 1 passes through a hall in a cradle 2, the tail having a larger transverse section on the conduit 1. The space between the conduit 1 and the side cradles Or of the tail is filled, by a filling material 3, which has the property that in the event of a fire it increases its volume ph such a sfitt, that it fills the part of the pipe area, which is destroyed or smashed by the fire.
Vid den i fig. 2 visade utfOringsformen Or uppfinningen tillampad vid en trycktat genomforing i brandsaker vagg. I vaggen 4, exempelvis en platvagg, Or en rektangular lade 5 insvetsad i en oppning i vaggen. I ladan 5 aro insatta elastiska passbitar 6, 7, 8, 9, vilka Oro utforda av det enligt uppfinningen anvanda materialet, som okar sin volym vid uppvarmning. Passbitarna Oro utfOrda i par med utvandigt parallellepipedisk form och med ett invandigt hOt, som Or avpassat att omsluta en ledning 10, 11, 12, 13. Som framgar av figuren kunn.a olika grova ledningar foras genom samma genomforing. De utrymmen, som icke upptagas av genomforda ledningar, kunna lampligen utfyllas med passbitar 14, 15 utan genomgaende hat. Genomforingen On Oven fOrsedd med en. icke narmare visad anordning 16 for hoptryckning av passbitarna i ladan 5, 2— — att genomfaringen blir trycktd.t. En dylik anordning kan lampligen utforas enligt ovannomnda svenska patentskrift 144 888 och 152 815. In the embodiment shown in Fig. 2, the invention is applied to a printed bushing in a firebox cradle. In the cradle 4, for example a plate cradle, Or a rectangular load 5 welded in an opening in the cradle. In the barn 5 are inserted elastic fitting pieces 6, 7, 8, 9, which are challenged by the material used according to the invention, which increases its volume when heated. The fitting pieces Oro are made in pairs with an externally parallelepiped shape and with an internal hut, which Or is adapted to enclose a conduit 10, 11, 12, 13. As can be seen from the figure, different coarse conduits can be passed through the same bushing. The spaces which are not occupied by through-laid pipes can suitably be filled with fitting pieces 14, 15 without continuous hatching. The bushing On Oven provided with a. device 16, not shown in more detail, for compressing the fitting pieces in the barn 5, 2— - that the passage is printed. Such a device can suitably be designed according to the above-mentioned Swedish patents 144,888 and 152,815.
