Attachment for supporting and fixing work structure cantilevered to wall during building construction, has fastener presenting deployed position in which mobile unit is tilted parallely with regard to longitudinal direction of body

摘要

The attachment has a fulcrum pin (B) located between a hook forming part (34) and a support leg forming part (36). A thrust part (44) is placed on a mobile unit (32). A maintenance finger (38) extends toward direction opposed to a rear end (16) of the leg forming part. A swivel fastener (10) presents a retracted position and a deployed position in which the mobile unit is tilted in a parallel manner with regard to longitudinal direction of a body (12), and the thrust part is supported against the body. An independent claim is also included for a method for fixing a fastener in a wall.
