Description

Mineraalivillaa oleva ohut eristyslevy kattorakenteita varten ja menetelmä eristyslevyn valmistamiseksiThin insulating sheet of mineral wool for roofing and method of manufacturing the insulating board

Esillä olevan keksinnön kohteena on mineraalivillaa oleva ohut eristyslevy kattorakenteita varten, jossa levyssä on mineraalivillaa oleva ydinkerros ja ainakin sen yhdelle puolelle järjestetty taipuisa pinnoite.The present invention relates to a thin insulating sheet of mineral wool for roofing structures having a core layer of mineral wool and a flexible coating arranged on at least one side thereof.

Erityisesti loivilla profiilipeltikatoilla käytettävien, mineraalivillaa olevien höyrynsulku-jen alustana toimivien levyjen eräänä ongelma on tullut esiin se, että nykyiset levyt voivat rikkoutua astuttaessa niiden päälle profiilipellin aukon kohdalla. Tämä aiheuttaa korjaustoimenpiteitä ja hidastaa asennustyötä. Rikkoutumisien välttämiseksi joudutaan käyttämään suhteellisen tiheitä ja paksuja ja siten painavia levyjä, jotka osaltaan hidastavat asennustyötä.One problem with panels that serve as a base for mineral wool vapor barrels, in particular on gently profiled sheet metal ceilings, is that existing panels may break when stepped on the profile sheet opening. This causes repairs and slows down the installation. In order to avoid breakage, relatively dense and thick and thus heavy plates have to be used, which in turn slows down the installation work.

Esillä olevan keksinnön päämääränä on aikaansaada parannettu ohut eristyslevy, jonka puristuslujuus- ja taivutuslujuusominaisuudet ovat huomattavasti paremmat kuin perinteisillä levyillä mahdollistaen aiempaa ohuemmat ja kevyemmät rakenteet. Tämän päämäärän saavuttamiseksi keksinnön mukaiselle ohuelle eristyslevylle on tunnusomaista se, että ydinkerros käsittää tyssäämällä muodostetun mineraalivilla-levyn, jossa kuidut pyrkivät tyssäyksen aikana suuntautumaan kohti levyn pääpinto-jen määrittämää tasoa, jonka ydinkerroksen kummallekin puolelle on järjestetty normin EN 13501-1 mukaisen paloluokan AI täyttävä taipuisa pinnoite, joka on kiinnitetty ydinkerrokseen mineraalivillalevyn omalla sideaineella ennen mineraalivillale-vyn karkaisua.The object of the present invention is to provide an improved thin insulating board having significantly better compressive and flexural strength properties than conventional boards, allowing for thinner and lighter structures. To achieve this object, the thin insulating board according to the invention is characterized in that the core layer comprises a mineral wool plate formed by refinement, in which the fibers tend to orient towards the level defined by the main surfaces of the board a coating applied to the core layer with a binder of mineral wool board prior to hardening of the mineral wool board.

Keksinnön mukaisella sandvvich-rakenteella on huomattavasti parantunut askelkes-tävyys yläpuolen pinnoitteen ottaessa vastaan puristusjännitystä ja alapuolen pinnoitteen ottaessa vastaan vetojännitystä. Tämä mahdollistaa nopeamman asennuksen, kun katolla ei tarvitse asennusvaiheessa varoa askeliaan kuten perinteisiä levyjä käytettäessä. Lisäksi kevyempi rakenne mahdollistaa useamman levyn kantamisen kerrallaan, nopeuttaen osaltaan asennustyötä.according to the invention, a sandwich structure is a vastly improved askelkes-resistance coating on the upper side when receiving the compressive stress and the underside of the coating receiving the tensile stress. This allows for quicker installation when the roof does not have to be careful about its steps during installation, as with traditional panels. In addition, the lighter construction allows for multiple panels to be carried at a time, helping to speed up installation work.

Seuraavassa keksintöä selostetaan lähemmin oheiseen piirustukseen viitaten, jossa: kuvio 1 esittää keksinnön mukaisen ohuen mineraalivillaa olevan eristyslevyn alkutilannetta, ja kuvio 2 kuvion 1 mukaista levyä kaaviollisena periaatekuvana valmiiksi muodostetussa tilassa.The invention will now be described in more detail with reference to the accompanying drawing, in which: Figure 1 shows an initial situation of a thin mineral wool insulating sheet according to the invention, and Figure 2 schematically illustrates the sheet of Figure 1 in a pre-formed state.

Kuviossa 1 on esitetty mineraalivillalevy 1, jossa kuidut 2 ovat levyn pääpintojen 3, 4 suuntaisissa tasoissa eli kuvan esittämässä tilanteessa olennaisesti vaakasuuntaisissa tasoissa. Levyä tyssätään puristamalla sitä vastakkaisista päistä voimalla F, jolloin kuidut 2 pyrkivät suuntautumaan kohti levyn pääpintoja. Kuviossa 2 on esitetty kaaviollisena periaatekuvana kuitujen suuntaus levyn tyssätyssä tilassa. Kuitujen suuntaus voi todellisessa tilanteessa poiketa huomattavastikin kuvion 2 esittämästä tilanteesta mutta pyrkimyksenä on saada kuidut suunnattua mahdollisimman pystyyn eli kohti levyn pääpintoja. Tyssäyksen jälkeen levyn kummallekin puolelle asetetaan pinnoite 5, 6, esim. lasikuituhuopaa, joka täyttää normin EN 13501-1 mukaisen paloluokan AI vaatimukset. Pinnoite kiinnitetään mineraalivillan omalla sideaineella, jonka jälkeen näin muodostettu molemmin puolin pinnoitettu levyl'viedään karkaistavaksi, jolloin pinnoite kiinnittyy lujasti mineraalivillaa olevaan ydinkerrok-seen. Yläpuolen pinnoite 5 toimii puristusjännityksiä vastaanottavana rakenteena ja alapuolen pinnoite 6 toimii puolestaan vetojännityksiä vastaanottavana rakenteena, esim. astuttaessa levyn päälle profiilipellin aukkokohdassa. Perinteisten levyjen ongelmana on ollut askel kestävyyden puutteiden lisäksi myös niiden riski katketa nostettaessa ja kannettaessa niitä katolla johtuen niiden alhaisemmasta taivutuslujuudesta. Keksinnön mukaisen sandwich-rakenteen ansiosta levyjen kestävyys nostettaessa ja kannettaessa niitä on aiempaa parempi.Figure 1 shows a mineral wool board 1 in which the fibers 2 are in planes parallel to the main surfaces 3, 4 of the board, i.e. in the position shown in the figure, in substantially horizontal planes. The plate is loaded by squeezing it at opposite ends with a force F, whereby the fibers 2 tend to be oriented towards the main surfaces of the plate. Figure 2 is a schematic diagram showing the orientation of the fibers in the loaded state of the sheet. The orientation of the fibers in the actual situation may differ significantly from that shown in Figure 2, but the tendency is to orient the fibers as vertically as possible, i.e. towards the main surfaces of the sheet. After curing, a coating 5, 6 is applied to each side of the board, eg fiberglass felt, which meets the fire resistance class AI according to EN 13501-1. The coating is fixed with a mineral wool binder, after which the thus formed coated plate is then subjected to tempering, whereby the coating adheres firmly to the core layer of mineral wool. The upper side coating 5 acts as a compressive stress on the receiving structure and the underside of the coating 6 is in turn tensile stresses on the receiving structure, e.g., when entering a profile on the plate in the hood opening. The problem with conventional boards has been not only the lack of durability but also their risk of breaking when lifted and carried on the roof due to their lower bending strength. Thanks to the sandwich construction of the invention, the boards have improved durability when lifted and carried.

Levyn 1' paksuus on edullisesti n. 30 mm ja ytimen muodostavan mineraalivillan tiheys on sopivimmin alueessa n. 120kg/m3-140 kg/m3. Levyn 1' pituus on edullisesti 1800 mm ja leveys 1200 mm. Nämä mitat ovat vain esimerkkejä edullisista arvoista ja keksintöä ei ole tarkoitettu rajoittumaan vain niihin.The thickness of the sheet 1 'is preferably about 30 mm and the density of the mineral wool forming the core is preferably in the range of about 120 kg / m 3 to 140 kg / m 3. The plate 1 'preferably has a length of 1800 mm and a width of 1200 mm. These dimensions are only examples of preferred values and the invention is not intended to be limited thereto.
