Device for mechanically destroying the top layer of supporting concrete floors

摘要

A device for mechanically destroying the slurry layer of supporting concrete floors is proposed, comprising a frame with a gripping bow and, on the underside of the frame, a rotary plate with rolling tools thereon. The rolling tools consist of discs, rollers or cylinders and are held by means of holders so as to be freely rotatable about those axes of rotation which are aligned approximately parallel to the rotary-plate plane and radially to its axis of revolution. The holders with rolling tools are resiliently supported for adaptation to surface differences.
