Abstract: A clamping device for use with or without a support saddle includes upper and lower filler bars adapted to extend along the upper and lower surfaces of a tongue like connecting member on an upstream deck panel. A pair of clamping bars are operable by a pair of bolts which extend though the filler bars and tongue like member upon placement of the panel atop the underlying support beams. Upon tightening the bolt, the free ends of the clamping bars bear against the underside of the support beam with the bolt head urging the tongue like member against the top of the beam so as to mechanically connect the panel to the beam. A support saddle has a pair of sidewalls of a selected height to space the overlying deck panel from the support beam. The top wall of the support saddle may be inclined to cant the deck panel relative to the support beam.
