Abstract:
A screwing device, which serves for screwing boards (2) onto underlying crossbeams (3) in such a way that the screws are screwed tilted in from the edges (5) of the boards (2). The screwing device includes a base (7) with an oblong foot (8) which in use stands on the upper side of the boards (2), two arms (9) extending tilted out from each their end of the foot (8), and two opposite screw drivers (10), which are mounted on each their arm (9) and each is arranged with means for conveying a disposable belt (34) of releasable screws (6) and for stepwise screwing in screws (6) from the belt (34). With the present invention, the components of a terrace can be screwed faster together than hitherto known, and at the same time the terrace obtains optimal strength.
