In order to hold a metal sheet 10 pressed onto a metal sheet 1 in a simple and inexpensive manner while the glue 9 inserted between these metal sheets takes, a rivet 7 with a head 6 is placed in a hole 4, 5 made in the metal sheets 1, 10, this rivet 7 having a second head 8 at its opposite end. Under the head 8 there is inserted a flange 11 with a hole 14 and with a fixed foot 15, whereas a threaded foot is inserted in the hole 14. In this way, it is possible to press the metal sheets 1, 10 against one another by screwing the foot towards the metal sheet 10 while the glue 9 takes; it is then possible to withdraw the flange 11 and to cut the rivet 7 when the glue 9 has taken. <IMAGE> |
