KATTOELEMENTIN VALMISTUSMENETELMÄ - FRAMSTÄLLNINGSFÖRFARANDE FÖR TAKELEMENTMETHOD OF MANUFACTURE A ROOF ELEMENT - FRAMSTÄLLNINGSFÖRFARANDE FÖR TAKELEMENT

Tämän Keksinnön kohteena on kattoelementin valmistusmenetelmä, jossa kahden metallilevyn väliin vaahdotetaan tai liimataan lämmöneriste kuten polyuretaani.The present invention relates to a method of manufacturing a roof element in which a thermal insulator such as polyurethane is foamed or glued between two metal sheets.

Epäkohtana tämän tapaisilla tunnetuilla valmistusmenetelmillä on se, että valmiiksiprofiloidun yläpellin katkaisu on vaikeaa ns. giljotiiniperiaatteella. Katkaisu on tehtävä kahdessa vaiheessa. Käytettäessä vaahdotettavia eristeitä kuten polyuretaania syntyy elementin pitkille sivuille vaikeasti hallittavia vuotoja. Eristeaine pursuaa konesauman uriin josta se on vaikea poistaa. Konesauma lisää elementin paksuutta n. 30 mm:llä, joten valmistusvaiheissa tämä vie muotin tehollista puristustilaa. Valmistettaessa kattoele-menttiä ns. jatkuvavalulinjalla joudutaan elementin ylä- ja alapelti viemään koneeseen lopulliseen muotoon profiloituna. Tämä lisää laitteiston vaatimaa tilaa pituussuunnassa, ja johtaa vaikeisiin teknisiin ratkaisuihin.A disadvantage of known manufacturing methods of this kind is that it is difficult to cut a pre-profiled top plate. giljotiiniperiaatteella. The disconnection must be done in two stages. When using foamable insulators such as polyurethane, leaks that are difficult to control on the long sides of the element occur. The insulation material exudes into the grooves of the machine seam where it is difficult to remove. The machine seam increases the thickness of the element by about 30 mm, so in the manufacturing stages this takes up the effective compression space of the mold. When manufacturing a roof element, the so-called the continuous casting line has to bring the upper and lower plates of the element into the machine into the final shape profiled. This increases the space required by the hardware in the longitudinal direction, and leads to difficult technical solutions.

Tämän keksinnön tarkoituksena on poistaa edellä mainitut epäkohdat. Keksinnön mukaiselle menetelmälle on tunnusomaista se, että eristeaineen kiinnityksen jälkeen profiloidaan rullamuovaustekniikalla ylälevyn reunoihin konesaumausta varten tarvittavat saumataitokset. Keksinnön avulla voidaan yläpelti katkaista sileänä tavanomaisilla levyleikkureilla. Sileä yläpelti saadaan mahdollisimman tiiviisti muotin väliin, joten haitallisia vuotoja ei pääse syntymään. Kone-sauman vaatima tila voidaan nyt käyttää tehollisesti. Neljän elementin asemesta voidaan samassa puristinvälissä valmistaa viisi elementtiä. Jatkuvavalulinjalla yläpelti tuodaan rullalta valulinjaan, jolloin valmistus muistuttaa yksinkertaista eriste-elementin valmistusta.The object of the present invention is to eliminate the above-mentioned drawbacks. The method according to the invention is characterized in that, after fixing the insulating material, the seam folds required for machine sealing at the edges of the top plate are profiled by means of a roll forming technique. By means of the invention, the top plate can be cut smoothly with conventional plate cutters. The smooth top plate is obtained as tightly as possible between the mold, so that no harmful leaks can occur. The space required by the machine seam can now be used efficiently. Instead of four elements, five elements can be produced in the same press spacing. In a continuous casting line, the top sheet is brought from the roll to the casting line, whereby the manufacture resembles the manufacture of a simple insulating element.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheiseen piirustukseen, jossa 2 63463The invention will now be described by way of example with reference to the accompanying drawing, in which 2 63463

Kuviot 1-4 esittävät kattoelementin yläpellin reunojen profilointia eri vaiheissa valmistettaessa polyure-taanieristeistä kattoelementtiä.Figures 1-4 show the profiling of the edges of the upper panel of the roof element at different stages in the manufacture of a polyurethane-insulated roof element.

Kattoelementin valmistusmenetelmässä vaahdotetaan polyuretaania 1 ylä- ja alapellin 2, 3 väliin. Vasta polyuretaanin 1 vaahdotuksen jälkeen profiloidaan rullamuovausteknii-kalla yläpellin 2 reunoihin konesaumausta varten tarvittavat saumataitokset 4, 5. Kuvion 1 mukainen elementti sijoitetaan rullaradalle, jonka vastakkaisilla reunoilla on rullilla varustetut profilointiasemat. Kuviot 2 ja 3 osoittavat miten reunaprofilointi etenee eli konesauman taitokset syntyvät. Lopullinen tuote on esitetty kuviossa 4.In the method of manufacturing the roof element, polyurethane 1 is foamed between the upper and lower dampers 2, 3. It is only after the foaming of the polyurethane 1 that the seam folds 4, 5 required for machine sealing are profiled at the edges of the upper sheet 2 by means of a roll forming technique. Figures 2 and 3 show how the edge profiling proceeds, i.e. the folds of the machine seam are created. The final product is shown in Figure 4.
