Description
Byggelement med forsta och andra tackskikt och mellanliggande karna TEKNISKT OMRADE Foreliggande uppfinning avser ett byggelement, vilket innefattar gtminstone ett forsta tackskikt och ett andra tackskikt som ar forbundna med motstgende sidor av en mellanliggande karna bestgende av gtminstone ett forsta karnmaterial och ett andra karnmaterial. Byggelennentet kan anvandas i barande bjalklag eller vaggar vid husbyggnation, foretradesvis vid byggnation av mindre hus. TECHNICAL FIELD The present invention relates to a building element which comprises at least a first roof layer and a second roof layer which are connected to opposite sides of an intermediate core consisting of at least one first core material and a second core material. The building element can be used in load-bearing joists or cradles for house construction, preferably for the construction of smaller houses.
UPPFINNINGENS BAKGRUND Olika typer av byggelement med sg kallad sandwichkonstruktion for anvandning i vagg och takkonstruktioner är kanda sedan tidigare. Ett exempel är sandwich-element som bestgr av en karna av polystyren- eller polyuretanskum som ge- nom limning forsetts med tackskikt av metallplgt pg den ena eller bagge si- dorna. En nackdel med denna typ av byggelement är att de snabbt kan forlora sin lastbarande formgga om de utsatts for hoga temperaturer i handelse av brand, eftersom plgtarna borjar bukta sig och karnmaterialet mjuknar eller till och med overggr i gasform sg att sandwichstrukturen kollapsar. BACKGROUND OF THE INVENTION Various types of building elements with so-called sandwich construction for use in cradle and roof constructions are known since before. An example is a sandwich element which consists of a core of polystyrene or polyurethane foam which, through gluing, is continued with a roof layer of metal plated on one or the ram sides. A disadvantage of this type of building element is that they can quickly lose their load-bearing form if they are exposed to high temperatures in the event of a fire, as the plows begin to bend and the core material softens or even becomes gaseous so that the sandwich structure collapses.
I SE 450 020 beskrivs ett byggelement som är avsett att losa det ovannamnda problemet med dglig brandhardighet. Detta byggelement innefattar en skivformig isoleringskarna av polystyren eller liknande material, samt tvg tunna stgliolgtar som tacker isolerskivans sidoytor. En ytterligare skiva, i form av en trafiber- eller gipsskiva eller liknande, är anordnad mellan gtminstone den ena plgten och isolerskivan. Den ytterligare skivan är avsedd att uppratthglla elementets lastbarande formgga under en viss tid dg elementet utsatts for yttre varme och att forhindra bildande av gasfas av karnmaterialet genom att isolera skivan frgn den yttre varmetillforseln och uppta latent varme frgn denna. SE 450 020 describes a building element which is intended to solve the above-mentioned problem of daily fire resistance. This building element comprises a sheet-shaped insulating core of polystyrene or similar material, as well as two thin steel sheets which thank the side surfaces of the insulating sheet. An additional board, in the form of a trafiber or gypsum board or the like, is arranged between at least one plate and the insulating board. The additional disc is intended to maintain the load-bearing shape of the element for a certain time when the element is exposed to external heat and to prevent the formation of a gas phase of the core material by insulating the disc from the external heat supply and absorbing latent heat therefrom.
Denna effekt uppngs genom att skivan delvis forkolnar nar en trafiberskiva an- vands och genom forgngning av kristallvatten nar en gipsskiva anvands. This effect is compensated by the fact that the board partially charred when a transport board is used and by the evaporation of crystal water when a plasterboard is used.
I EP 1 253 257 beskrivs ett forfarande for tillverkning av ett ytelement, for en vagg eller ett golv eller ett tak, som har en annan typ av sandwichkonstruktion. EP 1 253 257 describes a method for manufacturing a surface element, for a cradle or a floor or a roof, which has a different type of sandwich construction.
Det beskrivna forfarandet uppges Ora tillverkning av ytelement i olika storle- kar enklare och billigare och innefattar att ett flertal sandwichsskivor framstalls och varvid fOr framstallning av en sandwichskiva minst en isoleringsskiva pgfors en undre tackskiva och varvid en ovre tackskiva pgfors isoleringsskivan, varvid 1 de separata sandwichskivorna forbinds med varandra over sina sidokanter till en sandwichbana, varefter sandwichbanan sonderskars eller sondershas till de separata ytelementen. Tackskivorna i ytelennenten som tillverkas enligt EP 1 253 257 kan valjas frgn gruppen gipsskivor, traspgnskivor, vermikulitskivor, medan skivor av skummad plast, foretradesvis skumnnad polystyren, anvands som isoleringsskivor. Enligt EP 1 253 257 kan tackskivorna forbindas med isoleringsskivorna med hjalp av ett lim som kan vara ett polyuretanlim och isoleringsskivorna kan vara skilda frgn varandra med hjalp av fOrstarkningsribbor som foretradesvis bestgr av tra. The described method is stated in the manufacture of surface elements in different sizes simpler and cheaper and comprises that a plurality of sandwich discs are produced and wherein for the production of a sandwich disc at least one insulating disc is applied to a lower tack disc and wherein an upper tack disc is applied to the insulating disc, wherein the separate sandwich discs are connected to each other over their side edges to a sandwich web, after which the sandwich web is probed or probed to the separate surface elements. The roofing sheets in the surface element manufactured according to EP 1 253 257 can be selected from the group of gypsum boards, crankshaft boards, vermiculite boards, while boards of foamed plastic, preferably foamed polystyrene, are used as insulation boards. According to EP 1 253 257, the roofing sheets can be connected to the insulating boards with the aid of an adhesive which can be a polyurethane adhesive and the insulating boards can be separated from each other by means of reinforcing ribs which preferably consist of wood.
FOrutom det ovannamnda problemet med dglig brandhardighet har mgriga av de tidigare kanda byggelementen med sandwichkonstruktion nackdelen att de inte har tillracklig hglIfasthet och lastbarande formgga for att kunna anvandas i barande bjalklag eller vaggar utan att anvanda forstarkningsribbor eller mellan- liggande reglar av tra, barverk av metall, eller andra ytterligare stodkonstrukt- loner. Anvandningen av sgclana stodkonstruktioner av tra eller metall okar risken for fortplantning av stomljud i den fardiga byggnaden. In addition to the above-mentioned problem of daily fire resistance, many of the prior art sandwich construction components have the disadvantage that they do not have sufficient strength and load-bearing shape to be used in load-bearing joists or cradles without the use of reinforcing bars or intermediate bars of metal. , or other additional support structures. The use of sgclana standing structures of wood or metal increases the risk of reproduction of frame noise in the finished building.
