Abstract
A setting device ( 100 ) for mounting roof membranes ( 470 ) and insulation layers ( 450 ) on a substructure ( 460 ) uses an arrangement having a fastener ( 210 ) and a ferromagnetic load distribution washer ( 200 ) for fastening. The setting device includes a movable frame ( 130 ) having a first feed device ( 110 ) for load distribution washers and a second feed device ( 120 ) for fasteners. The setting process starts with manual actuation of a vertically arranged pressure rod ( 145 ) that can be telescoped against a spring. A drive unit ( 150 ) attached thereto with a motor-driven drive mandrel ( 155 ) drives a fastener from a mounting guide ( 320 ) through a load distribution washer held in a mounting guide in the base assembly ( 310 ) of the setting device. A magnet system, designed so that the load distribution washer to be set is fixable in a suspended manner in the mounting bracket ( 300 ) without an additional mechanical retainer, is used.
