Abstract (en)

[origin: EP0860617A1] The ceiling is fixed in place using a hammer head screw (10) which has a tension spring (26) that abuts the screw head (16) and a clamp (20) pushed on to the screw shank (22) and which pulls the clamp towards the screw head. The tension spring is an elastic ring or an elastic band with a fastening for mounting on the clamp of the screw head. The screw may alternatively have a compression spring to press the clamp towards the screw head. This can be a spring washer.
