Verfahren zur Verbindung von Verbundelementen

摘要

The invention is concerned with binding together compound elements that exhibit the following layered structure: (i) 2 to 20 mm metal layer, (ii) 10 to 100 mm polyisocyanate or polyaddition product layer obtained by mixing (a) isocyanates with (b) compounds that react with isocyanates, (iii) 2 to 20 mm metal layer. The invention is characterised in that the (i) and (iii) of the compound elements respectively extend beyond the compound layer (ii) by a distance (x) of at least 7.5 cm; the compound layers are respectively fixed to each other; and (a) isocyanates are reacted with (b) compounds that react thereto in the space between the two compound layers (i) and (iii).
