Description
7714834-4 10 15 20 25 30 35 stånd med upp till 50% trots att de belagda sidoytorna av lamellerna sammanfaller med eldens genomträngningsriktning. 7714834-4 10 15 20 25 30 35 with up to 50% even though the coated side surfaces of the slats coincide with the direction of penetration of the fire.
Enligt uppfinningen uppnås alltså ett kraftigt förbättrat brandskydd även om det svårbrännbara materialet eller flam- skyddet ej står hindrande i vägen för eldens frontala angrepp.According to the invention, a greatly improved fire protection is thus achieved even if the non-combustible material or flame protection does not stand in the way of the frontal attack of the fire.
Förklaringen härtill torde vara att eldfronten uppdelas i ett flertal smärre zoner motsvarande lamelltjockleken varvid eld- angreppet blir försvagat i riktning mot de mellan lamellerna befintliga beläggningarna. i Uppfinningen skall nedan beskrivas under hänvisning till bifogade ritning som visar ett utföringsexempel av ett parti av en dörr i perspektiv och genomskärning. Å ritningen betecknar l0 och l2 två täckskivor som vardera kan vara ut- förda i ett eller flera skikt av hårda träfiberplattor respek- tive fanêr el.dyl. De är limmade vid en inre stomme som är sammansatt av kantställda lamellstavar 14 av fibermaterial t.ex. i porös form. Runt kanterna kan stommen begränsas av än ram l6 av massivt trä. Enligt uppfinningen är mellan de mot varandra anliggande lamellerna anbragt en beläggning l8 av ett flamskyddande salt, som är obrännbart respektive mera svårbrännbart än fibermaterialet och som har denna egenskap antingen i sig själv eller sedan det utsättes för en tempe- raturförhöjning genom eldpåverkan. Saltet utgöres företrädes- vis av flamskyddande fosfater, borater eller sulfater av i och för sig känt slag. Mängden av beläggningen kan uppgå till ao-iso 9/m2.The explanation for this should be that the fire front is divided into a number of smaller zones corresponding to the lamella thickness, whereby the fire attack is weakened in the direction of the coatings between the lamellae. The invention will be described below with reference to the accompanying drawing which shows an embodiment of a portion of a door in perspective and section. In the drawing, l0 and l2 denote two cover plates which can each be made of one or more layers of hard fibreboard or veneer or the like. They are glued to an inner frame which is composed of edged lamella rods 14 of fibrous material e.g. in porous form. Around the edges, the frame can be limited by than frame l6 of solid wood. According to the invention, a coating 18 of a flame retardant salt is arranged between the abutting slats, which is non-combustible and more non-combustible than the fibrous material and which has this property either by itself or after it is subjected to a temperature increase by fire. The salt preferably consists of flame-retardant phosphates, borates or sulphates of a kind known per se. The amount of coating can amount to ao-iso 9 / m2.
Vid eldangrepp mot dörrens flatsida enligt den av pi- len 20 antydda huvudriktningen dvs. i vinkel mot dörrplanet förmår beläggningarna 18 fördröja eldens genomträngningstid med upp till 50% vilket innebär en mycket stor förbättring och vilket alltså uppnås även om de mot täckskivan l2 vända flanksidorna av lamellerna helt saknar brandskyddsmedel. An- ledningen härtill är såsom ovan antytts sannolikt att elden i stället för att arbeta sig in genom stommen med en samman- hängande front över dörrytan, endast förmår separat intränga i de enskilda stavarna pâ sätt som antytts med de streck- W prickade linjerna 22. En spärr bildas åt sidorna av belägg- l0 15 20 771 4834-14 ningarna 18 mellan de enskilda lamellerna så att den samman- hängande eldfronten bryts upp och dämpas.In the event of a fire attack on the flat side of the door according to the main direction indicated by the arrow 20, ie. at an angle to the door plane, the coatings 18 are able to delay the penetration time of the fire by up to 50%, which means a very large improvement and which is thus achieved even if the flank sides of the slats facing the cover plate 12 have no fire protection. The reason for this, as indicated above, is probably that the fire, instead of working its way through the frame with a continuous front over the door surface, is only able to penetrate separately into the individual rods in the manner indicated by the dashed lines 22. A barrier is formed on the sides of the coatings 18 between the individual slats so that the continuous fire front is broken up and damped.
Fosfor avger i hög värme gasformiga fosforprodukter som kan flytta på sig och som vid kontakt med cellulosan har en dehydratiserande effekt varvid stabila kolskelett upprättas.Phosphorus emits in high heat gaseous phosphorus products which can move and which on contact with the cellulose have a dehydrating effect whereby stable carbon skeletons are established.
Med ett flamhärdande salt av denna art erhålles sålunda den ytterligare effekten att det fibrösa materialet övergår till en förkolnad form, som ytterligare fördröjer eldens genom- brytning av dörren el.dyl.With a flame-curing salt of this kind, the additional effect is thus obtained that the fibrous material changes to a charred form, which further delays the penetration of the fire of the door or the like.
Ett-särskilt lämpligt sätt att tillverka de skivfor- miga byggnadselementens stommar utmärkes därav att samman- hängande skivor av stommaterialet först belägges på ena tller båda flatsidorna med den flamskyddande respektive svårbränn- bara kompositionen. Dessa skivor sågas sedan upp i stavar av vilka stommen sammansättes varvid beläggningen kommer att befinna sig vid kontaktytorna mellan lamellerna. Lamellerna behöver icke förenas med varandra medelst bindemedel.A particularly suitable way of manufacturing the frames of the sheet-shaped building elements is characterized in that continuous sheets of the frame material are first coated on one or both flat sides with the flame-retardant and non-combustible composition, respectively. These discs are then sawn into rods of which the frame is assembled, the coating being located at the contact surfaces between the slats. The slats do not need to be joined together by means of adhesive.
Uppfinningen är givetvis icke begränsad till den visa- de utföringsformen utan kan varieras i ett eller annat av- seende inom ramen av detföreliggande kravet.The invention is of course not limited to the embodiment shown but can be varied in one respect or another within the scope of the present claim.
