Abstract
A fixing device for use in fixing insulating boards and waterproof sheeting, if required, to be fixed with the insulating boards on a sheet panel forming a cover plate for a flat roof, includes a sleeve inserted into a drilled hole extending through the waterproof sheeting, the insulating board, and the sheet panel, the lower end of the sleeve projecting beyond the sheet panel and including an expandable part which is opened out beyond the drilled hole diameter by tightening a nut on a bolt which passes through a plate or disc-like abutment element and the bore of the sleeve. The fixing device is made such that it can be detached again so that the roof covering can be repaired, renewed, and reconstructed, if required, without causing significant damage to the sheet panel.
