ABSTRACT:
A decking plate is arranged on a cover plate over the open top of a U shaped channel, such that a through hole of the decking plate is positioned aligned over a cutout portion of the cover plate. A fixture is inserted through the through hole and the cutout portion. The fixture includes a head, a screw, a tube like portion and a protrusion. The cover plate and the decking plate are pinched and fixed together between the head and the protrusion of the feature. Thus, a positioned displacement of a attached plurality of plates can be prevented.
