发明名称 FLOOR CONSTRUCTION COMPRISING JOISTS PROVIDED WITH LEVEL ADJUSTING SPACER SCREWS, JOISTS AND SPACER SCREWS THEREFOR
摘要 A building construction for floors including joists that have vertical, threaded, through-running holes for level-adjusting spacer screws, which protrude from the joist on its underside for adjusting the top side of the joist to a desired level, an elastic damping body being arranged at the anterior screw portion and having an outer part, which forms a resilient connection between the screw and the substructure, and an inner part, which is located inside a central hole in the screw. The inner part forms a resilient engagement element for cooperation with an inner support surface in the bottom part of the screw. An attachment element for anchoring the screw to the substructure extends through a central hole in the damping body. The cross section of the inner part is greater than the diameter of the bottom part.
