Description
Cr: 10 20 25 30 81056M~2 profilelement och det tillverkningsförfarande, som anges i kraven. Cr: 10 20 25 30 81056M ~ 2 profile elements and the manufacturing method, as stated in the claims.
Genom att utrymmet i den profilerade plattans toppar är helt utfyllt av värmeisolerande material, som häftar vid topparnas insidor och som intill isolerskivan är komprimer- bart, elimineras effektivt luftcirkulationen i topparna, varigenom såväl ett spridande av eventuellt uppkommande brand som kondensbildning på topparnas insidor förhindras.Because the space in the profiles of the profiled plate is completely filled with heat-insulating material, which adheres to the insides of the tops and which is compressible next to the insulating board, the air circulation in the tops is effectively eliminated, thereby preventing both fire and condensation from forming inside the tops.
Dessutom blir topparna tack vare närvaron av det värmeiso- lerande materialet i topparna väsentligt mera motståndskraf- tiga, så att risken för knäckning eller buckling elimineras eller åtminstone yäsentligt minskas. Genom att det värme- isolerande materialet i topparna är komprimerbart åtminstone intill isolerskivan, uppnås den speciella fördelen, att ut- rymmet i topparna alltid är helt utfyllt av värmeisolerande material, som tätande anligger mot topparnas insidor och mot isolerskivan, även vid rörelser i taket t ex på grund av va- rierande belastning eller värmespänningar. Uppdelningen av det värmeisolerande materialet i två skikt gör det möjligt att använda ett styvare eller stelare material i topparnas yttre delar, vilket ger en bättre styvhet hos den profilera- de plattan och förbättrad gåbarhet.In addition, due to the presence of the heat-insulating material in the tops, the tops become significantly more resistant, so that the risk of buckling or buckling is eliminated or at least significantly reduced. Because the heat-insulating material in the tops is compressible at least next to the insulating board, the special advantage is achieved that the space in the tops is always completely filled with heat-insulating material, which seals against the insides of the tops and against the insulating board, even during movements in the roof. eg due to varying load or thermal stresses. The division of the heat-insulating material into two layers makes it possible to use a stiffer or stiffer material in the outer parts of the tops, which gives a better rigidity of the profiled plate and improved walkability.
Genom att vid tillverkningen av det laminerade profil- elementet enligt uppfinningen delvis fylla den profilerade plattans toppar med ett plastskum och sedan utfylla resten av utrymmet i topparna med ett material, som komprimeras in i topparna och sedan ytterligare kan komprimeras, när plast- skummet vid härdningen expanderar, erhålles en mycket god vidhäftning mellan plastskummet och insidorna i den profile- rade plattans toppar, eftersom plastskummet under härdningen och även efteråt av det komprimerbara materialet pressas mot den profilerade plattan. Dessutom kan isolerskivan sammanfo- gas med den profilerade plattan, så snart som det komprimer- bara materialet har pålagts, så att profilelementet snabbt kan färdigställas. Plastskummet kan sålunda härda under ele- mentets lagring, och härdningen behöver alltså icke ske, medan elementet ligger kvar i formverktyget eller jiggen.By manufacturing the laminated profile element according to the invention in part by partially filling the tops of the profiled plate with a plastic foam and then filling the rest of the space in the tops with a material which is compressed into the tops and can then be further compressed when the plastic foam during curing expands, a very good adhesion is obtained between the plastic foam and the insides of the tops of the profiled plate, since the plastic foam is pressed against the profiled plate during curing and also afterwards by the compressible material. In addition, the insulating board can be joined to the profiled plate as soon as the compressible material has been applied, so that the profiling element can be completed quickly. The plastic foam can thus harden during storage of the element, and the hardening thus does not have to take place while the element remains in the mold or jig.
En utföringsform av det laminerade profilelementet en- ligt uppfinningen och ett utföringsexempel på tillverknings- ll] '.-' U 25 St) 35 8105644-2 förfarandet skall nu närmare beskrivas nedan med hänvisning till de bifogade ritningsfigurerna.An embodiment of the laminated profile element according to the invention and an exemplary embodiment of the manufacturing method will now be described in more detail below with reference to the accompanying drawing figures.
Pig. 1 visar en del av ett laminerat profilelement en- ligt uppfinningen i perspektivvy. 7 Pig. 2 visar profilelementet enligt fig. 1 delvis upp- skuret, varvid den profilerade plattans toppar har vänts nedåt ..Pig. 1 shows a part of a laminated profile element according to the invention in perspective view. 7 Pig. 2 shows the profile element according to Fig. 1 partially cut up, the tops of the profiled plate having been turned downwards.
Det i fig. 1 visade profilelementet innefattar en pro- filerad platta 10, vilken är försedd med ett flertal paral- lella toppar 11 och mellan dessa toppar liggande förbindelse- delar 12. Plattan utgöres av en till trapetsform profilerad aluminiumplåt. Den profilerade plattan 10 är vid sina för- bindelsedelar 12 sammanfogad med en skiva 13 av värmeisole- rande material, t ex cellplast. De av den profilerade plat- tans toppar 11 bildade utrymmena mellan den profilerade plat- tan och isolerskivan är helt utfyllda med värmeisolerande ma- terial. Detta värmeisolerande material består av ett första skikt 14 av komprimerbart material, t ex mineralull eller glasull, vilket är anordnat intill isolerskivan, och ett and- ra skikt 15 av plastskum, t ex ett pulyuretanskum, vilket är anordnat i topparnas yttre del. Det första skiktet 14 består av ett material, som är lätt att komprimera och som är elas- tiskt, så att det återtar sin ursprungliga form, när den komp- rimerande kraften upphör. Det andra skiktet 15 består av ett material, som är väsentligen stelt. lsolerskivan 13 är samman- fogad med den profilerade plattan 10 genom limning. Skiktet 10 bör ha en tjocklek, som är åtminstone en femtedel av topparnas höjd.The profile element shown in Fig. 1 comprises a profiled plate 10, which is provided with a plurality of parallel peaks 11 and connecting parts 12 lying between these peaks. The plate consists of an aluminum plate profiled in a trapezoidal shape. The profiled plate 10 is joined at its connecting parts 12 to a board 13 of heat-insulating material, eg cellular plastic. The spaces formed by the profiles 11 of the profiled plate 11 between the profiled plate and the insulating board are completely filled with heat-insulating material. This heat-insulating material consists of a first layer 14 of compressible material, for example mineral wool or glass wool, which is arranged next to the insulating sheet, and a second layer 15 of plastic foam, for example a polyurethane foam, which is arranged in the outer part of the tops. The first layer 14 consists of a material which is easy to compress and which is elastic, so that it regains its original shape when the compressive force ceases. The second layer 15 consists of a material which is substantially rigid. The insulating board 13 is joined to the profiled plate 10 by gluing. The layer 10 should have a thickness which is at least one-fifth of the height of the peaks.
Profílelementet tillverkas genom att först ett plast- skum lb, L ex ett polyuretanskum, fylles i den profilerade plattans 10 toppar 11, när dessa är vända nedåt, såsom visas i fig. 2. Topparna fylles endast delvis, t ex ungefär till den nivå, som svarar mot halva topphöjden. Därefter anbringas ett komprimerbart material 1H på plastskummet i topparna, varvid det komprimerbara materialet har en volym, som är stör- re än det återstående utrymmet i topparna, såsom visas i den uppskurna delen av profilelementet. Det komprimerbara mate- rialet är lämpligen, men icke nödvändigtvis, i form av rem- sor, som har profilerats så, att den i topparna inskjutande (fl 10 15 20 25 awsamf-z i i i i a delen av remsorna har en form, som overensstämmer med formen på det återstående utrymmet i topparna. Eftersom remsorna har en större volym än det återstående utrymmet i topparna, kommer de att delvis skjuta ut ur topparna, såsom visas i fig. 2. När det komprimerbara materialet har anbringats i topparna, påföres lim på den profilerade plattans förbin- delsedelar 12 och eventuellt även på det komprimerbara ma- terialet, vilket kan ske i en vanlig limningslinje; Alter- nativt kan limmet påföras isolerskivan 13. Därefter pålägges och pressas isolerskivan mot den profilerade plattan 10, var- vid det komprimerbara materialet inpressas i topparna, såsom framgår av fig. 2. Det färdiga profilelementet överföres där- efter till ett lager, där plastskummet får hårda. Under denna härdning expanderar plastskummet 15 i topparna, men denna expansion tas upp av det komprimerbara materialet 14, som därvid ytterligare komprimeras. Det komprimerbara materialet blir sålunda under tillverkningen starkt komprimerat och bi- drager i viss mån till att pressa plastskummet mot topparnas insidor, så att en god vidhäftning mellan den profilerade plå- ten och plastskummet i topparna säkerställes under profilele- mentets hela livstid, även om profilelementet utsättes för stora och varierande belastningar. Tack vare det komprimerbara materialets kompressibilitet och elasticitet säkerställes, att det värmeisolerande materialet i den profilerade plattans toppar alltid tätande anligger mot såväl den profilerade plat- tan 10 som mot isolerskivan 13, varigenom luftcirkulation ge- nom topparna förhindras, så att risken för spridning av brand och uppkomsten av kondens elimineras eller väsentligt minskas.The profile element is manufactured by first filling a plastic foam 1b, L eg a polyurethane foam, into the tops 11 of the profiled plate 10, when these are turned downwards, as shown in Fig. 2. The tops are only partially filled, for example approximately to the level which corresponds to half the top height. Thereafter, a compressible material 1H is applied to the plastic foam in the tops, the compressible material having a volume which is larger than the remaining space in the tops, as shown in the cut-out part of the profile element. The compressible material is suitably, but not necessarily, in the form of strips which have been profiled so that the awsamf-z in each part of the strips has a shape which corresponds to the shape. Since the strips have a larger volume than the remaining space in the tops, they will partially protrude from the tops, as shown in Fig. 2. Once the compressible material has been applied to the tops, glue is applied to the profiled the connecting parts 12 of the plate and possibly also on the compressible material, which can be done in an ordinary gluing line; Alternatively, the glue can be applied to the insulating plate 13. Then the insulating plate is applied and pressed against the profiled plate 10, whereby the compressible material is pressed in the tops, as shown in Fig. 2. The finished profile element is then transferred to a layer, where the plastic foam gets hard.During this curing, the plastic foam 15 expands in top but this expansion is taken up by the compressible material 14, which is then further compressed. The compressible material is thus strongly compressed during manufacture and contributes to some extent to pressing the plastic foam against the insides of the tops, so that a good adhesion between the profiled plate and the plastic foam in the tops is ensured during the entire life of the profile element, even if the profile element exposed to large and varying loads. Thanks to the compressibility and elasticity of the compressible material, it is ensured that the heat-insulating material in the tops of the profiled plate always abuts tightly against both the profiled plate 10 and the insulating plate 13, thereby preventing air circulation through the tops, so that the risk of fire spreading and the occurrence of condensation is eliminated or significantly reduced.
Endast den fukt, som kan diffundera genom det värmeisolerande materialet, kan kondensera, och denna fuktmängd är väsentligt mindre än den fuktmängd, som kan passera in i topparna genom luftens konvektion i öppna eller endast delvis fyllda toppar.Only the moisture which can diffuse through the heat-insulating material can condense, and this amount of moisture is substantially less than the amount of moisture which can pass into the peaks by the convection of the air into open or only partially filled peaks.
Om det värmeisolerande materialet i topparnas yttre del, dvs skiktet 15, är väsentligen stelt, erhålles en väsentlig lüvulyvníng av det profileradc ulemonLuL och en väsentlig för- stärkning av topparna, som medför att risken för skador på topparna under lagringen, under transporter, under montage och på grund av belastningar under brukstiden väsentligt minskas. '_10 lb 20 30 3105644-2 C71 Det blir alltså möjligt att gå på ett tak, som har konstrue- rats med profilelement enligt uppfinningen, utan risk för att topparna skadas. Samtidigt bibehåller emellertid profilele- mentet en god förmåga att ta upp pàkänningar på grund av va- rierande belastningar och värmespänningar, genom att det komprimerbara skiktet lä intill isolerskivan 13 är eftergiv- ligt. Härigenom minskas risken för att t ex värmespänningar skall medföra,att den profilerade plattan 10 separeras från isolerskivan 13. Även om endast en utföringsform och ett utföringsexem- pel beskrivits ovan, är det uppenbart, att många olika ut- föríngsformer och tillverkningsförfaranden är möjliga inom ramen för uppfinningstanken, Det värmeisolerande materialet i topparna och i isolerskivan kan väljas inom en stor grupp av lämpliga material, och den profilerade plattan behöver icke bestå av aluminiumplåt eller metallplåt utan kan även utgöras av t ex plast. Plattans profilering behöver icke va- ra trapetsformad, utan även andra former är möjliga.If the heat-insulating material in the outer part of the tops, ie the layer 15, is substantially rigid, a substantial smoothing of the profiled ulemonLuL is obtained and a significant reinforcement of the tops, which entails the risk of damage to the tops during storage, during transport, during assembly and due to loads during the service life is significantly reduced. It will thus be possible to walk on a roof which has been constructed with profile elements according to the invention, without risk of the tops being damaged. At the same time, however, the profile element maintains a good ability to absorb stresses due to varying loads and thermal stresses, in that the compressible layer adjacent to the insulating plate 13 is resilient. This reduces the risk that, for example, thermal stresses will cause the profiled plate 10 to separate from the insulating sheet 13. Although only one embodiment and one embodiment have been described above, it is obvious that many different embodiments and manufacturing methods are possible within the framework. The heat-insulating material in the tops and in the insulating board can be selected from a large group of suitable materials, and the profiled plate does not have to consist of aluminum sheet or metal sheet but can also consist of, for example, plastic. The profiling of the plate does not have to be trapezoidal, but other shapes are also possible.
Vid tillverkningen behöver icke det komprimerbara ma- terialet påläggas i form av remsor, utan det kan även utgö- ras av mer eller mindre flytande material, som pålägges i form av strängar. Det är även möjligt att använda samma mate- rial i hela utrymmet i topparna, under förutsättning att det- ta material âtminstone intill isolerskivan uppvisar en viss komprimerbarhet. Limmet kan påföras på många sätt, t ex genom sprutning eller rollning, och kan täcka endast förbindelse- delarna på den profilerade plattan eller såväl förbindelse- delarna som det komprimerbara materialet. Det material, som skall bilda det yttre skiktet i topparna, kan vid införingen i topparna vara i mer eller mindre flytande form, men måste vara lätt formbart, så att materialet utfyller topparna obe- roende av eventuella variationer i dessas dimensioner på grund av tillverkningstoleranser.During manufacture, the compressible material does not need to be applied in the form of strips, but it can also consist of more or less liquid material, which is applied in the form of strands. It is also possible to use the same material in the entire space in the tops, provided that this material at least next to the insulating board shows a certain compressibility. The adhesive can be applied in many ways, for example by spraying or rolling, and can only cover the connecting parts on the profiled plate or both the connecting parts and the compressible material. The material which is to form the outer layer in the tops may, when inserted into the tops, be in a more or less liquid form, but must be easily moldable, so that the material fills the tops regardless of any variations in their dimensions due to manufacturing tolerances.
