Abstract

A deck-retaining clamp assembly secures a corrugated deck panel to a support cable that underlies and supports the deck panel, the deck panel having in a lower web portion an elongated opening that overlies a segment of the support cable and extends transversely of the support cable. A U-bolt engages the cable from below, and a clamp plate is tightened against the upper surface of the deck panel by at least one nut threaded onto one leg of the U-bolt. A handle attached to one of the legs of the U-bolt permits manipulation of the U-bolt to engage it with the support cable. The handle has a grip portion that is shaped and dimensioned such that it cannot pass through the hole in the clamp plate and a shank portion that is movable through the hole in the clamp plate and is of a length such that the U-bolt can be moved down relative to the clamp plate to a position such that the upper end of the U-bolt is at a level below the lowermost extremity of the support cable. Thus, the U-bolt can be engaged with the cable segment by inserting it through the opening in the deck panel laterally adjacent the cable segment, lowering it relative to the clamp plate, displacing it and the clamp plate along the opening in the deck plate, and lifting it by the handle to engage the cable segment in nested relation in the loop portion.

In a work platform in which a deck-retaining clamp assembly secures a corrugated deck panel to a support cable that underlies and supports the deck panel, the deck panel having in a lower web portion an elongated opening that overlies a segment of the support cable and has a longer dimension that extends transversely of the support cable and a shorter dimension that is aligned with the cable, the improvement wherein the clamp assembly comprises

a U-bolt having spaced-apart first and second leg portions of equal lengths and a loop portion joining the leg portions, the leg portions being adapted to straddle the cable and the loop portion being adapted to accept the support cable in nested relation and the first and second leg portions having external threads adjacent their ends;
a nut threaded onto the external threads of each of the leg portions in the installed position of the assembly;
a clamp plate having a width that is substantially greater than the smaller dimension of the opening and a length substantially greater than the longer dimension of the opening so as to be adapted to engage the upper surface of the lower web of the deck panel along portions of the lower web bordering the entire perimeter of the opening and having a first hole receiving the first leg portion and a second hole receiving the second leg portion in the installed position of the assembly;
and
a handle releasably attached to the end of the first leg portion of the U-bolt, the handle having a grip portion and a shank portion, the grip portion being shaped and dimensioned such that it cannot pass through the first hole in the clamp plate and the shank portion being movable through the first hole in the clamp plate and having a length such that the U-bolt can be moved by manipulation of the handle to a position such that the end of the second leg portion is below the lowermost extremity of the support cable, whereby the U-bolt can be engaged with the cable segment by inserting it through the opening in the web portion of the deck panel laterally adjacent the cable segment, lowering it relative to the clamp plate, displacing it along the opening in the deck plate, and lifting it to engage the cable segment in nested relation in the loop portion.
