The transporter is provided with wheels so as to be movable and is used to transport and position the decking panels and/or the shoring means. Lifting means is provided on the transporter to selectively raise or lower a decking panel to a desired position. Once a decking panel is properly positioned by the transporter, the shoring means are utilized to support the decking panels and the transporter is removed. Each decking panel has mounted on its upper surface a plate on which concrete is poured. Each shoring means is provided with adjusting means for selectively adjusting the length thereof to facilitate the positioning and removal of the shoring means.

Claim 1
Independent Claim
244 words
A set of elements for use in a portable decking system for the construction of building units having a monolithic slab roof, said elements comprising: a movable transporter for moving and positioning decking panels, said transporter comprising a support frame adapted to receive a decking panel on the upper portion thereof, movable means mounted on the lower portion of said support frame to enable said transporter to be moved on a support surface, and lifting means mounted on said support frame and engageable with a decking panel mounted thereon to move it upwardly above said upper portion to a desired position; a decking panel adapted to be supported on the upper portion of said transporter and moved upwardly to a predetermined position by said lifting means for the pouring of concrete thereon; and a plurality of vertically adjustable shoring means adapted to be removably positioned on and conveyed by said transporter, said shoring means being removable from said transporter and adapted to engage and support said decking panel in said predetermined position to enable said transporter to be removed from said decking panel after it is moved to said predetermined position; said transporter being movable beneath said decking panel after curing of the concrete thereon and said shoring means being movable downwardly out of engagement with said decking panel after said transporter is moved beneath said decking panel to enable said decking panel to be moved away from said predetermined position by said transporter.
