Description
Anordning til beskyttelse mot flammerDevice for protection against flames
Denne oppfinnelse vedrører en anordning til beskyttelse av underlag, f.eks. ved-sveise- og loddarbeide mot forbrenning ved sveise- eller loddeflammer. This invention relates to a device for protecting substrates, e.g. wood-welding and soldering work against burns from welding or soldering flames.
Særlig ved' fyringsanlegg kreves det flammevernanordnin-ger når rørledninger legges innenfor bygninger. Bygningsveggér, som f.eks. kan være av mineralske materialer, er ømfintlige over-for heteinnvirkning og av denne grunn er det ved legging av rør-ledninger langs bygningsveggene nødvendig å legge beskyttelse for veggen mot de eksisterende sveise- eller lpddesteder. Det område hvor det f.eks. sveises en sveisesøm, får en kortvarig beskyttelse ved pålegging av en asbestplate på veggen umiddelbart bak sveise-stedet. Asbestplater som brukes til dette formål, har imidlertid lett for å brekke og de er også vanligvis gjennombrent når sveise-arbeidet er avsluttet, slik at det kan forekomme skader på de underlag som egentlig■skulle beskyttes mot sveiseflammen ved hjelp av platene. Asbestplater er også ufordelaktige ved at de ikke kan tilpasses uregelmessig formede underlag, fordi de nesten ikke er bøyelige. Particularly in the case of heating plants, flame protection devices are required when pipelines are laid inside buildings. Building walls, such as can be made of mineral materials, are sensitive to the effects of heat and for this reason, when laying pipelines along the building walls, it is necessary to provide protection for the wall against the existing welding or soldering points. The area where, for example, If a weld seam is welded, a short-term protection is obtained by placing an asbestos sheet on the wall immediately behind the welding spot. Asbestos sheets used for this purpose, however, break easily and they are also usually burned through when the welding work is finished, so that damage can occur to the substrates that should actually be protected from the welding flame by means of the sheets. Asbestos sheets are also disadvantageous in that they cannot be adapted to irregularly shaped substrates, because they are almost inflexible.
Hensikten med denne oppfinnelse er å forbedre en anordning av den innledningvis nevnte art for oppnåelse av en fullkom-men beskyttelse mot hete. The purpose of this invention is to improve a device of the type mentioned at the outset for achieving complete protection against heat.
Denne oppgave er ifølge oppfinnelsen løst ved hjelp av en pute som dekker over underlaget og er av varmebestandig vevstoff og med en putefylling som består av varmeabsorberende pasta. According to the invention, this task is solved with the help of a pillow that covers the substrate and is made of heat-resistant fabric and with a pillow filling that consists of heat-absorbing paste.
Det varmebestandige vevstoff er fortrinnsvis et asbestvevstoff med på yttersiden pådampet aluminium, som skjæres til og syes på vanlig måte til en pute. Den aluminiumpådampede overflate leder raskt bort varmen som avgis fra en flamme som treffer over-flaten, slik at lokale overhetninger, som kunne føre til beskadi-gelse av asbesten,ikke eller nesten ikke kan forekomme. Som putefylling fylles i putens hulrom en varmeabsorberende pasta. Baksi- den-av puten som ligger direkte på underlaget, holdes derved all-tid forholdsvis kjølig. Også putefyIlingens pasta kan meget godt lede bort varme og fordele den jevnt, slik at eventuelle lokale overhetninger unngås og dermed også gjennombrenningen av puten. The heat-resistant fabric is preferably an asbestos fabric with vapor-deposited aluminum on the outside, which is cut to size and sewn in the usual way into a pillow. The aluminium-steamed surface quickly dissipates the heat emitted from a flame that hits the surface, so that local overheating, which could lead to damage to the asbestos, cannot or almost cannot occur. As pillow filling, a heat-absorbing paste is filled into the pillow's cavity. The back side of the cushion, which lies directly on the surface, is thereby kept relatively cool at all times. The pillow filling's paste can also conduct heat very well and distribute it evenly, so that any local overheating is avoided and thus also the burning of the pillow.
Anvendelsen av en pasta som putefylling er også fordelak-tig ved at anordningen ifølge oppfinnelsen er meget fleksibel og lett og enkelt kan tilpasses ujevnt og uregelmessig formede underlag som skal beskyttes. The use of a paste as a cushion filling is also advantageous in that the device according to the invention is very flexible and can easily and simply be adapted to uneven and irregularly shaped substrates to be protected.
Oppfinnelsen .skal forklares nærmere ved hjelp av tegnin-gen som viser sett fra siden en delvis oppskåret pute 1 fremstilt av asbestvevstoff 3 med åluminiumbelegg 2. Putens innerrom er fylt med en varmeabsorberende pasta 4. The invention will be explained in more detail with the help of the drawing which shows, viewed from the side, a partially cut pillow 1 made of asbestos fabric 3 with an aluminum coating 2. The inner space of the pillow is filled with a heat-absorbing paste 4.
