Description
Foreliggende oppfinnelse vedrører en takplate av den art som The present invention relates to a roof plate of the type which
er angitt i krav l's ingress'. is stated in claim l's preamble'.
En kjente plate til bruk i byggeindustrien består av et lacj uorganiske fibre og et vanntett dekklag. Denne platen har utmerkede isolerings- og branntekniske egenskaner, men har samtidig den ulempe at den ikke er selvbærende. Ved anvendelse av plater av den nevnte tyne som takplater er det derfor nødvendig å tilveiebringe selvstendige støtte- A known board for use in the construction industry consists of a layer of inorganic fibers and a waterproof cover layer. This board has excellent insulation and fire-technical characteristics, but at the same time has the disadvantage that it is not self-supporting. When using boards of the aforementioned thickness as roof boards, it is therefore necessary to provide independent support
elementer for platene. elements for the plates.
Trebetongplater, dvs. plater bestående av lange trefibre Wood concrete slabs, i.e. slabs consisting of long wood fibres
som er belagt med sement, og som er sammenbundet under trykk er blitt anvendt som selvbærende takelementer. Slike ' trebetongplaters relativt dårlige bøyestivhet medfrtrer imidlertid at det kreves relativt tykke plater, dvs. plater med en tykkelse på over 10 cm for å gjøre dem selvbærende. Slike tykke plater er meget tunge og vanskelige å håndtere- which are coated with cement and which are connected under pressure have been used as self-supporting roof elements. However, the relatively poor bending stiffness of such wooden concrete slabs means that relatively thick slabs are required, i.e. slabs with a thickness of over 10 cm to make them self-supporting. Such thick plates are very heavy and difficult to handle -
I beskrivelsen til engelsk patent nr. 1.445.787 er det omtalt It is mentioned in the description of English patent no. 1,445,787
en sammensatt plate omfattende to trebetongplater, hvori-mellom det er innlagt en plate fremstilt av et stivt skum av et syntetisk formstoffmateriale. a composite plate comprising two wooden concrete plates, between which is inserted a plate made of a rigid foam of a synthetic molding material.
Selv om.forholdet mellom styrke oa tykkelse økes sammenliknet med en enkelt trebetongplate ved å tilveiebringe et laminat som beskrevet i ovennevnte engelske patentbeskrivelse, kreves det relativt tykke og som følge herav tunge trebetongplater Although the ratio between strength and thickness is increased compared to a single wood concrete slab by providing a laminate as described in the above-mentioned English patent description, relatively thick and consequently heavy wood concrete slabs are required
for å gjøre slike plater selvbærende. to make such plates self-supporting.
Formålet med den foreliggende oppfinnelse er å tilveiebringe en relativt lett selvbærende, isolerende takplate som er særpreget ved det som er angitt i krav 1' s karakteriserende del. The purpose of the present invention is to provide a relatively light self-supporting, insulating roof sheet which is characterized by what is stated in claim 1's characterizing part.
Ifølge oppfinnelsen tilveiebringes en takplate som er karakterisert ved at den omfatter et øvre lag fremstilt av organiske fibre og som er laminert med en trebetongnlate. According to the invention, a roof sheet is provided which is characterized in that it comprises an upper layer made of organic fibers and which is laminated with a wooden concrete slab.
Det har således vist seg at det ved å laminere et lag uorganiske fibre med en relativt tynn trebetongplate, dvs. It has thus been shown that by laminating a layer of inorganic fibers with a relatively thin wooden concrete slab, i.e.
en plate med en tykkelse på ca. 3,5 cm, ved hjeln av et organisk bindemiddel oppnås det en plate med en overraskende stor bøyestivhet. s a plate with a thickness of approx. 3.5 cm, with the help of an organic binder, a plate with a surprisingly high bending stiffness is obtained. pp
Eksempelvis har det vist seg at hvis et mineralfiberlag med en tykkelse på 8 cm lamineres med en trebetongplate med en tykkelse på 3,5 cm dannes det en plate med en bøyestivhet som er.tilstrekkelig stor til å gjøre platen selvbærende over et spenn på 1,8 m. Ved anvendelse av et mineralfiberlag med en tykkelse på 18 cm oppnås en nlate som er selvbærende over et spenn på 2,4 m. For example, it has been shown that if a mineral fiber layer with a thickness of 8 cm is laminated with a wooden concrete slab with a thickness of 3.5 cm, a slab is formed with a bending stiffness that is sufficiently large to make the slab self-supporting over a span of 1, 8 m. By using a mineral fiber layer with a thickness of 18 cm, a nlate is achieved that is self-supporting over a span of 2.4 m.
Som følge av anvendelsen av en relativt tynn trebetongnlate As a result of the use of a relatively thin wooden concrete slab
er vekten av den sammensatte takplate ifølge opnfinnelsen betydeliq lavere enn vekten av de kjente trebetoncrnlater. the weight of the composite roof panel according to the invention is significantly lower than the weight of the known wooden concrete panels.
Laget av organisk bindemiddel er fortrinnsvis tynt for å gjøre den sammensatte platen motstandsdyktig mot brann, idet platens resterende bestanddeler, nemlig laget av uorganiske fibre oa trebetongplaten, begge er motstandsdyktige mot brann. Ved anvendelse av slike tynne lag av oraanisk bindemiddel er det blitt fremstilt sammensatte plater med en gjennombrenninas-tid på over 6 0 minutter. The layer of organic binder is preferably thin in order to make the composite board resistant to fire, as the board's remaining components, namely made of inorganic fibers and the wood concrete board, are both fire resistant. By using such thin layers of orange binder, composite boards have been produced with a burn-through time of over 60 minutes.
Laget av uorganiske fibre er fortrinnsvis fremstilt av mineralull og spesielt steinull. Andre slags uorqaniske fibre som glassullfibre kan imidlertid oqså anvendes. The layer of inorganic fibers is preferably made from mineral wool and especially stone wool. However, other types of inorganic fibers such as glass wool fibers can also be used.
Dekklaget som er tilveiebrakt på laget av uorganiske fibre fremstilles fortrinnsvis av takpapp som kan være sammensatt av et eller flere lag. The covering layer which is provided on the layer of inorganic fibers is preferably produced from roofing paper which can be composed of one or more layers.
Som ovenfor nevnt har trebetongplaten fortrinnsvis en tykkelse på ca. 3,5 cm. As mentioned above, the wooden concrete slab preferably has a thickness of approx. 3.5 cm.
Laget av organisk bindemiddel er fortrinnsvis fremstilt av skumformstoff for derved å gi den sammensatte platen for-bedrede akustiske og terminske isoleringsegenskaper. Tykkelsen på et slikt skumformet formstofflag er fortrinnsvis mellom 5 og 20 mm. The layer of organic binder is preferably made of foam molding material to thereby give the composite board improved acoustic and thermal insulation properties. The thickness of such a foam-shaped molding material layer is preferably between 5 and 20 mm.
En særlig foretrukken utførelsesform for den sammensatte takplate ifølge oppfinnelsen har et dampsperre-skikt, f.eks. en metallfolie som er innlagt i laget av organisk bindemiddel. En slik metallfolie forhindrer damp i å trenge inn i laget av mineralfibre fra undersiden av den sammensatte plate og derved redusere lagets isoleringsegenska<p>er. A particularly preferred embodiment of the composite roof panel according to the invention has a vapor barrier layer, e.g. a metal foil embedded in the layer of organic binder. Such a metal foil prevents steam from penetrating the layer of mineral fibers from the underside of the composite plate and thereby reducing the layer's insulating properties.
En aluminiumsfolie innlagt i et lag polyuretanskum har vist seg å være spesielt godt egnet som følge av at polyuretanen kleber godt til aluminiumsfolien. Det skal dog bemerkes at også andre metallfolier er anvendelige. An aluminum foil embedded in a layer of polyurethane foam has proven to be particularly well suited as a result of the polyurethane sticking well to the aluminum foil. However, it should be noted that other metal foils are also applicable.
Eksempler på andre bindemidler, som er egnede til bruk ved fremstilling av sammensatte plater ifølge oppfinnelsen, er fenolharpikser og <p>olyestere. Examples of other binders, which are suitable for use in the production of composite panels according to the invention, are phenolic resins and polyesters.
Det øvre lag av den sammensatte plate ifølge oppfinnelsen er fortrinnsvis anbrakt forskjøvet i; forhold til trebetongplaten slik at kanten av fiberlaget på en plate kan bringes til å over- The upper layer of the composite plate according to the invention is preferably placed offset in; relation to the wood-concrete slab so that the edge of the fiber layer on a slab can be brought to over-
lappe kanten av trebetongplaten i en tilstøtende sammensatt takplate. En slik konstruksjon har en forbedret brannmot-standsdyktighet, og fuktighetsspredningen i mellomrommene mellom tilstøtende plater er redusert. lap the edge of the wood concrete slab into an adjacent composite roof slab. Such a construction has an improved fire resistance, and the spread of moisture in the spaces between adjacent boards is reduced.
En ytterligere fordel ved de sammensatte plater ifølge oppfinnelsen er at de kan fremstilles på et løpende bånd. A further advantage of the composite plates according to the invention is that they can be produced on a conveyor belt.
Således kan de sammensatte plater fremstilles ved suksessivt Thus, the composite plates can be produced successively
å innføre trebetongplater anbrakt på et løpende bånd og en metallfolie i et sprøytekammer, hvori et skumdannenende formstoffmateriale påsprøytes oversiden av trebetongplatene og metallfolien. Trebetongplatene, metallfolien oa et lag av uorganiske fibre lamineres derpå ved hjelp av det skumdannende materialet. Under oppskumningsprosessen trenger formstoffmaterialet inn i overflatene av trebetongplatene og fiberlagene og det dannes sterke bindinger. introducing wooden concrete slabs placed on a conveyor belt and a metal foil into a spray chamber, in which a foam-forming molding material is sprayed onto the upper side of the wooden concrete slabs and the metal foil. The wooden concrete slabs, the metal foil and a layer of inorganic fibers are then laminated using the foam-forming material. During the foaming process, the molding material penetrates the surfaces of the wood concrete slabs and fiber layers and strong bonds are formed.
Oppfinnelsen skal heretter beskrives mere detaljert under henvisning til tegningen som viser et tverrsnittsbilde av kantområdet av en sammensatt plate ifølge oppfinnelsen. The invention will now be described in more detail with reference to the drawing which shows a cross-sectional view of the edge area of a composite plate according to the invention.
På tegningen betegner 1 et mineralfiberlag med et vanntett dekklag 2 bestående av to lag takpapp. Et lag 3 av polyuretanskum, hvori det er innlagt en aluminiumsfolie 4 med en tykkelse på f.eks. 4 0 pm, er anbrakt mellom mineralfiber- In the drawing, 1 denotes a mineral fiber layer with a waterproof cover layer 2 consisting of two layers of roofing felt. A layer 3 of polyurethane foam, in which an aluminum foil 4 with a thickness of e.g. 4 0 pm, is placed between mineral fiber
laget 1 og en trebetongplate 5 med en tykkelse på f.eks. layer 1 and a wooden concrete slab 5 with a thickness of e.g.
3,5 cm til dannelse av en sammensatt plate. 3.5 cm to form a composite plate.
Polyuretanlaget. 3 tjener ikke alene som bindemiddel men bibringer også den sammensatte platen en øket termisk og akustisk isoleringsevne. The polyurethane layer. 3 not only serves as a binding agent but also gives the composite board an increased thermal and acoustic insulation capacity.
Som det fremgår av tegningen er mineralfiberlaget 1 anbrakt As can be seen from the drawing, the mineral fiber layer 1 has been placed
litt forskjøvet i forhold til trebetongplaten 5. For- slightly offset in relation to the wooden concrete slab 5. For-
skyvningen som f.eks. kan være av størrelsesorden 35 mm fører til at kantområdet av en sammensatt plates mineralfiberlag 1 kommer til å overlappe kantområdet på en til-støtende sammensatt plates trebetongplate 5. the push as e.g. can be of the order of 35 mm causes the edge area of a composite board's mineral fiber layer 1 to overlap the edge area of an adjacent composite board's wooden concrete board 5.
En trefiberstrimmel 6 er anbrakt mellom trebetongplaten 5 og mineralfiberlaget 1 langs kantene av den sammensatte plate for derved å begrense det skumdannende materiale og for å danne støtte for eventuelle festeorganer som er anbrakt i mellomrommene mellom tilstøtende sammensatte platers mineralfiberlag 1. A wood fiber strip 6 is placed between the wood concrete plate 5 and the mineral fiber layer 1 along the edges of the composite plate in order to thereby limit the foam-forming material and to form support for any fasteners that are placed in the spaces between the mineral fiber layer 1 of adjacent composite plates.
