Description
Foreliggende oppfinnelse vedrører et system for dannelse av hårde skott for kabel- eller blindskottdannelse. The present invention relates to a system for forming hard bulkheads for cable or blind bulkhead formation.
Ved bygging av brannsikre rom må det ved murgj ennombrudd som er nødvendige for kabel, rør, luftesjakter henholdsvis -åpninger treffes brannbeskyttelsesforholdsregler for å forhindre en utbredning av brann. En hittil kjent mulig brannbeskyttelsesforholdsregel er f.eks. lukking av murgj ennombrudd for kabelgjennomføringer ved tilmuring, henholdsvis lukking, ved hjelp av brannbeskyttelseskitt, brannbeskyttelsesmørtler, silikonskum eller intumescerende masser, eventuelt i forbindelse med mineralullplater. Ulempen ved disse brannbeskyttelsesforholdsreglene er imidlertid at de tildels ikke oppnår noen tilstrekkelig brannmotstandsklasse, idet f.eks. åpninger som i branntilfellet oppstår ved smelting av kabler, eksempelvis ved utelukkende anvendelse av brannbe-skyttelsesmørtler ikke lukkes fullstendig, eller at de for det meste må tilpasses på omstendelig måte. En ytterligere ulempe ved hittil kjente brannbeskyttelsesforholdsregler på gipsbasis er den begrensede anvendelsesmuligheten ved gipskartongvegger, idet disse ved innbygging av på stedet fremstillbare gipsmørtler dertil gjennomfuktes ved det nødvendige vannet, hvilket igjen kan føre til statiske problemer. When building fire-proof rooms, fire protection precautions must be taken to prevent the spread of fire in case of wall breaks that are necessary for cables, pipes, ventilation shafts or openings. A previously known possible fire protection precaution is e.g. closing of wall openings for cable entries by walling, respectively closing, using fire protection putty, fire protection mortars, silicone foam or intumescent masses, possibly in connection with mineral wool sheets. However, the disadvantage of these fire protection precautions is that they sometimes do not achieve an adequate fire resistance class, as e.g. openings that in the event of fire occur when cables are melted, for example by exclusively using fire protection mortars, are not completely closed, or that they mostly have to be adapted in a cumbersome way. A further disadvantage of previously known plaster-based fire protection measures is the limited applicability of plasterboard walls, as these are wetted by the required water when incorporating plasterboard mortars that can be produced on site, which in turn can lead to static problems.
Oppgaven ved foreliggende oppfinnelse var følgelig å finne en mulighet til å utforme brannbeskyttelsesinnretninger for kabel- eller blindskottdannelse på en slik måte at de kan bygges inn henholdsvis tilpasses uten stor omstendelighet, hvorved det samtidig sikres en brannmotstandsvarighet på minst 90 minutter ifølge CSN 730851. The task of the present invention was therefore to find an opportunity to design fire protection devices for cable or blind bulkhead formation in such a way that they can be built in or adapted without great difficulty, whereby at the same time a fire resistance duration of at least 90 minutes is ensured according to CSN 730851.
Uventet kunne denne oppgaven løses ved et skottdannelsessystem som består av spesielle brannbeskyttelsesteglstein, eventuelt i kombinasjon med et intumescerende materiale. Unexpectedly, this task could be solved by a bulkhead formation system consisting of special fire protection bricks, possibly in combination with an intumescent material.
Gjenstand for foreliggende oppfinnelse er følgelig et system for dannelse av hårde skott for kabel- eller blindskottdannelse, kjennetegent ved at det består av a) brannbeskyttelsesteglstein av gipsmørtel, kalkgipsmørtel, sementmørtel, perlittmørtel eller vermikulittmørtel, eventuelt i kombinasjon med The object of the present invention is therefore a system for the formation of hard bulkheads for cable or blind bulkhead formation, characterized in that it consists of a) fire protection bricks made of gypsum mortar, lime gypsum mortar, cement mortar, perlite mortar or vermiculite mortar, possibly in combination with
b) intumescerende materiale og/eller b) intumescent material and/or
c) mineralull, c) mineral wool,
hvorved systemet eventuelt er utstyrt med en puss. whereby the system is optionally equipped with a plaster.
Foretrukne utførelsesformer av oppfinnelsen er angitt i søknadens uselvstendige krav. Preferred embodiments of the invention are indicated in the application's non-independent claims.
Komponent a) av skottdannelsessystemet ifølge oppfinnelsen består av brannbeskyttelsestegl på mørtelbasis. Component a) of the bulkhead formation system according to the invention consists of fire protection tiles on a mortar basis.
Egnede materialer for fremstilling av tegl er derved alle mørteltyper med høy isolasjons-verdi, henholdsvis lavt varmegjennomgangstall. Mørtel er derved betegnelsen for en kunstig stein som oppstår fra en blanding av et eller flere uorganiske bindemidler, tilslag inntil 4 mm kornstørrelse, vann og eventuelt mørteltilslag, som f.eks. vermikulitt eller perlitt ved herding av bindemiddelet. Avhengig av typen av bindemiddel henholdsvis tilslag skiller man derved mellom blant annet gipsmørtel, kalkgipsmørtel, sementmørtel, vermikulittmørtel osv. Foretrukket er mørtler på basis av gips og vermikulitt, perlitt. Spesielt foretrukket anvendes mørtler på gipsbasis. Suitable materials for the production of bricks are therefore all types of mortar with a high insulation value, respectively a low heat transfer coefficient. Mortar is thus the term for an artificial stone that arises from a mixture of one or more inorganic binders, aggregates up to 4 mm grain size, water and possibly mortar aggregates, such as e.g. vermiculite or perlite when curing the binder. Depending on the type of binder or aggregate, a distinction is made between, among other things, gypsum mortar, lime gypsum mortar, cement mortar, vermiculite mortar, etc. Mortars based on gypsum and vermiculite, perlite are preferred. Gypsum-based mortars are particularly preferred.
Formen, størrelsen og dermed antallet av de anvendte teglene kan variere avhengig av størrelsen av åpningen som skal utrustes brannsikkert. Følgelig kan eksempelvis ved blindskottdannelse åpningen som skal lukkes lukkes med bare en teglstein svarende til størrelsen av åpningen, det kan også imidlertid bygges inn flere mindre teglstein. Ved kabelskottdannelse kan det prinsipielt gås frem som ved blindskottdannelse, det må her imidlertid ved innbygning av teglsteinene spares ut tilstrekkelig plass til kabelbunten henholdsvis kabeltraséen. Formen av teglsteinen tilsvarer fortrinnsvis et kvadrat eller en rettvinklet pyramidestump, spesielt foretrukket en rettvinklet pyramidestump. Foretrukket er teglstein med en grunnflate på 50 til 500 mm lengde og 20 til 150 mm bredde og en høyde på 20 til 100 mm. Dekkflaten av den kvadratformige teglen tilsvarer derved den ovenfor definerte grunnflaten, ved pyramidestumpformige teglstein er dekkflaten mindre enn grunnflaten. Foretrukket er følgelig pyramidestumpformige teglstein med en dekkflate på 30 til 300 mm lengde og 20 til 150 mm bredde. Bredden av dekkflaten kan derved tilsvare bredden av grunnflaten, slik at formen av teglen tilsvarer formen av en gullbarre. Formen og størrelsen av teglsteinen må imidlertid tilpasses til de eventuelle gitte forutsetningene og kan dermed om ønsket over- henholdsvis underskride de ovenfor definerte størrelsene. Fremstillingen av gipsteglen foregår for gipsbearbeidelse på vanlig måte, eksempelvis ved blanding med en armering, tilslag som flytendegjørende middel, farge osv. og helles i form med vann og las tørke. Innbyggningen av teglsteinene i åpningen som skal gjøres brannsikker foregår på vanlig måte ved hjelp av mørtler, henholdsvis puss, som sikrer et tilstrekkelig vedheng til teglen. Det kan derved eksempelvis anvendes puss, henholdsvis mørtel, som gispspuss, kalk- og kalk-sementpuss osv. Fortrinnsvis anvendes brannbeskyttelsesmørtel, som f.eks. vermikulitt-mørtel. The shape, size and thus the number of bricks used can vary depending on the size of the opening to be fireproofed. Consequently, for example, when creating a blind bulkhead, the opening to be closed can be closed with just one brick corresponding to the size of the opening, but several smaller bricks can also be built in. When creating a cable bulkhead, you can in principle proceed as with the creation of a blind bulkhead, but here, when installing the bricks, sufficient space must be saved for the cable bundle or the cable route. The shape of the brick preferably corresponds to a square or a right-angled truncated pyramid, particularly preferably a right-angled truncated pyramid. Bricks with a base surface of 50 to 500 mm length and 20 to 150 mm width and a height of 20 to 100 mm are preferred. The covering surface of the square brick thereby corresponds to the base surface defined above, in the case of truncated pyramidal bricks, the covering surface is smaller than the base surface. Preference is therefore given to truncated pyramidal bricks with a covering surface of 30 to 300 mm in length and 20 to 150 mm in width. The width of the cover surface can thereby correspond to the width of the base surface, so that the shape of the brick corresponds to the shape of a gold bar. The shape and size of the brick must, however, be adapted to the possible given conditions and can therefore, if desired, exceed or fall below the sizes defined above. The production of the plaster brick takes place for plaster processing in the usual way, for example by mixing with a reinforcement, aggregates such as liquefying agent, color etc. and is poured into the form with water and allowed to dry. The installation of the bricks in the opening that is to be made fireproof takes place in the usual way with the help of mortars, respectively plaster, which ensures a sufficient attachment to the brick. For example, plaster or mortar can be used, such as gypsum plaster, lime and lime-cement plaster, etc. Fire protection mortar is preferably used, such as e.g. vermiculite mortar.
Brannbeskyttelsesteglsteinene a) innbygges fortrinnsvis i kombinasjon med en intumescerende masse som komponent. Som intumescerende masse b) egner seg derved alle masser som skummer opp i branntilfelle, som er oppnåelige i form av laminater, kitt, dispersjoner, oppløsninger eller pastaer. Eksempler på dette er brannbeskyttelses-masser på basis av blæregrafitt eller av alkalisilikater, masser på basis av flammefast innstilte, med nitrogenholdige eller fosforholdige esemidler modifiserte polyvinylacetat-dispersjoner, på basis av med lateksdispersjoner modifiserte, vandige alkalisilikater eller på basis av flammefast modifiserte, nitrogen- eller fosforholdige esemidler inne-holdende polyuretaner. The fire protection bricks a) are preferably installed in combination with an intumescent mass as a component. All masses that foam in the event of fire, which are obtainable in the form of laminates, putty, dispersions, solutions or pastes, are therefore suitable as intumescent mass b). Examples of this are fire protection compounds based on blister graphite or alkali silicates, compounds based on flame-resistant polyvinyl acetate dispersions modified with nitrogen-containing or phosphorus-containing blowing agents, based on aqueous alkali silicates modified with latex dispersions or on the basis of flame-resistant modified, nitrogen- or phosphorus-containing foaming agents containing polyurethanes.
Brannbeskyttelsesmassene kan også inneholde bindemidler, som f.eks. polyvinylacetat, polyvinylakrylat, polyvinylklorid-blandpolymerisater eller polykloroprener og karbon-henholdsvis skorpedannere, som f.eks. sukker, melasse, polyimider, polyakrylnitril, fenolharpikser, melaminharpikser eller fosfonater. Slike intumescerende brannbeskyt-telsesmasser er eksempelvis beskrevet i EP-B-0 153564. De er også kommersielt til-gjengelige, eksempelvis under varenavnet "Intumex" fra Chemie Linz. Ved anvendelse av skottdannelsessytemet ifølge oppfinnelsen for kabelskottdannelse innbygges komponent b) fortrinnsvis på en slik måte at kabelene, henholdsvis kabelbuntene, dekkes med komponent b). Videre er det mulig at komponent b) samtidig tjener som bevegelsesfuge. I dette tilfelle bygges brannbeskyttelsesmassen inn mellom vegg og brannbeskyttelsestegl a). Dette kan eksempelvis foregå i form av bånd, rullede systemer, brannbeskyttelsespolstere, brannbeskyttelsessilikon, brannbeskyttelsesfugemasse osv. Anordningen av komponenetene a) og b) samt typen av komponent b) må imidlertid igjen tilpasses de aktuelle forholdene. Videre kan skottdannelsessystemet ifølge oppfinnelsen også understøttes med mineralull som komponent c). Innbygningen av en mineralullstripe og/eller en brannbeskyttelsesmasse b) i fugen mellom vann og brannbeskyttelsestegl stabiliserer skottdannelsessystemet mot rystelser, henholdsvis vibrasjoner. Trekkene b) og c) kan derved anvendes alene eller også i kombinasjon, eksempelvis ved anbringelse på siden av mineralull og over- henholdsvis under teglene, anbringelse av brannbeskyttelsessilikon eventuelt i kombinasjon med en avdekking av kabeltraséen ved hjelp av komponent b). The fire protection compounds can also contain binders, such as e.g. polyvinyl acetate, polyvinyl acrylate, polyvinyl chloride mixed polymers or polychloroprenes and carbon respectively crust formers, such as e.g. sugar, molasses, polyimides, polyacrylonitrile, phenolic resins, melamine resins or phosphonates. Such intumescent fire protection compounds are, for example, described in EP-B-0 153564. They are also commercially available, for example under the trade name "Intumex" from Chemie Linz. When using the bulkhead formation system according to the invention for cable bulkhead formation, component b) is preferably incorporated in such a way that the cables, respectively the cable bundles, are covered with component b). Furthermore, it is possible that component b) also serves as a movement joint. In this case, the fire protection compound is built in between the wall and the fire protection tile a). This can, for example, take place in the form of tape, rolled systems, fire protection padding, fire protection silicone, fire protection sealant, etc. The arrangement of components a) and b) as well as the type of component b) must, however, again be adapted to the relevant conditions. Furthermore, the bulkhead formation system according to the invention can also be supported with mineral wool as component c). The incorporation of a mineral wool strip and/or a fire protection compound b) in the joint between water and fire protection tiles stabilizes the bulkhead formation system against tremors or vibrations. The features b) and c) can thereby be used alone or in combination, for example by placing mineral wool on the side and above and below the tiles, placing fire protection silicone possibly in combination with a covering of the cable route using component b).
Skottdannelsessystemet ifølge oppfinnelsen kan, avhengig av kravene til systemet, utstyres med en puss. For forhøyelse av fastheten og vannbestandigheten for systemet, samt av optiske grunner, pusses systemet fortrinnsvis. Som puss egner seg eksempelvis alle vanlige pussmørtler basert på gips, kalk, sement, som f.eks. mørtelgipser, ferdig-pussgipser, maskinpussgipser, heftpussgipser osv. Fortrinnsvis anvendes derved bran-beskyttelsesmørtel, som f.eks. vermikulittmørtel. The bulkhead formation system according to the invention can, depending on the requirements of the system, be equipped with a plaster. To increase the firmness and water resistance of the system, as well as for optical reasons, the system is preferably plastered. As plaster, for example, all common plaster mortars based on plaster, lime, cement, such as e.g. mortar plaster, ready-to-plaster plaster, machine-plaster plaster, self-plaster plaster, etc. Fire protection mortar, such as e.g. vermiculite mortar.
Skottdannelsessystemet ifølge oppfinnelsen egner seg for kabel-og blindskottdannelse i vegg- og dekkeområdet. Fortrinnsvis anvendes systemet i veggområdet. Ved kombina-sjonsmulighetene for komponentene a) til c), eventuelt med en puss, kan systemet optimalt og på enkel måte tilpasses til de aktuelle kravene og det oppnås en brannmotstandsvarighet på minst 90 minutter. The bulkhead formation system according to the invention is suitable for cable and blind bulkhead formation in the wall and roof area. The system is preferably used in the wall area. With the combination options for components a) to c), possibly with a plaster, the system can be optimally and simply adapted to the relevant requirements and a fire resistance duration of at least 90 minutes is achieved.
Fremstilling av gipstegl Production of gypsum tiles
For fremstilling av 100 stk. teglstein med et grunnriss på 80 mm bredde, 160 mm lengde, en høyde på 40 mm og en dekkflate på 80 mm bredde og 130 mm lengde ble det blandet 45 kg gips ("G2-B-IT, "CSN 722303", firma Gipstrend) med 1 kg perlitt ("Experlit EP 150", firma Kerko Kosice). Videre fremstilles en blanding av 601 vann med 1,9 kg rød "Vollton"farge (firma Richard Sommer GmbH) og 0,45 kg "Liquidment N" (firma Chemie Linz). Deretter ble gipsblandingen innført i vannblandingen, las stå i ca. 2 minutter og utrøres til en homogen blanding. Denne massen helles så i tilsvarende former og las tørke. For the production of 100 pcs. brick with a ground plan of 80 mm width, 160 mm length, a height of 40 mm and a covering surface of 80 mm width and 130 mm length, 45 kg of gypsum ("G2-B-IT, "CSN 722303", company Gipstrend ) with 1 kg of perlite ("Experlit EP 150", company Kerko Kosice). Furthermore, a mixture of 601 water with 1.9 kg of red "Vollton" color (company Richard Sommer GmbH) and 0.45 kg of "Liquidment N" ( company Chemie Linz).The plaster mixture was then introduced into the water mixture, left to stand for about 2 minutes and stirred to a homogeneous mixture. This mass was then poured into corresponding molds and allowed to dry.
Eksempel 1 Example 1
Det ble utført en branntest ved et system bestående av kabeltrasé, gipsteglstein fremstilt ifølge det ovenstående eksempelet, som ble murt inn ved hjelp av "Perlfix" (mørtel på basis av perlit), samt "Intumex F", som tjente som komponent b). A fire test was carried out on a system consisting of cable route, gypsum bricks produced according to the above example, which were bricked in using "Perlfix" (mortar based on perlite), as well as "Intumex F", which served as component b).
Oppbygningen, samt målepunktene fremgår av firgur 1. The structure, as well as the measurement points, can be seen in figure 1.
For montasje av systemet for hårdskottdannelse ble det anvendt en hjelpakonstruksjon av stålblikk med U-profil 100 x 50 x 0,6 mm som blikkomramming. For kabeltrasé-simulering ble det anvendt et stålblikk med målene 250 mm bredde x 120 mm lengde x 2,5 mm tykkelse. "Intumex F" ble derved påført midt på traséen og hadde målene 20 x 20 x 250 mm (ca. 100 cm<3>). For assembly of the system for forming hard bulkheads, an auxiliary construction of sheet steel with U-profile 100 x 50 x 0.6 mm was used as sheet framing. For cable route simulation, a steel sheet with the dimensions 250 mm width x 120 mm length x 2.5 mm thickness was used. "Intumex F" was thus applied in the middle of the route and had the dimensions 20 x 20 x 250 mm (approx. 100 cm<3>).
Branntemperaturen tilsvarte ISO-kurven (norm ?). Temperaturene på målepunktene ble målt i 10 minutters avstand og fremgår av tabell 1. Resultatet av forsøket var at systemet for dannelse av hårde skott ved 100 mm tykkelse oppnådde en brannmotstandsvarighet på minst 120 minutter. Også stabiliteten av systemet var uforandret etter 130 minutter. The fire temperature corresponded to the ISO curve (norm ?). The temperatures at the measurement points were measured 10 minutes apart and can be seen in table 1. The result of the experiment was that the system for forming hard bulkheads at a thickness of 100 mm achieved a fire resistance duration of at least 120 minutes. The stability of the system was also unchanged after 130 minutes.
Eksempel 2: Example 2:
Analogt eksempel 1 ble det fremstilt et system for dannelse av hårdskott, bestående av "Intumex F" for dekking av den simulerte kabeltraséen og gipstegl fremstilt ifølge det ovenstående fremstillingseksempelet, som ble murt inn ved hjelp av "Intumex V", og underkastet en branntest (norm ?). Analogously to example 1, a system for the formation of hard bulkheads was produced, consisting of "Intumex F" for covering the simulated cable route and gypsum tiles produced according to the above production example, which were bricked in using "Intumex V", and subjected to a fire test ( norm?).
Forsøksforløpet fremgår av figur 2. De målte temperaturene fremgår av tabell 2. Brann-motstandsvarigheten utgjorde minimalt 100 minutter. The test sequence is shown in figure 2. The measured temperatures are shown in table 2. The fire resistance duration was a minimum of 100 minutes.
