Abstract
An ergonomic method for transporting and installing a sheet of metal decking in a composite floor or roof structure having underlying I-beams. A carrier with a flat top surface is loaded with the next sheet of decking to be installed in the next open position on the beams. The carrier has an inclined surface and upon reaching the next open position the next sheet of decking is rested on the inclined surface with lifting hooks. An ironworker pushes the next sheet of decking down the inclined surface towards the next open position and working the ends of the next sheet of decking with ribs and flat sections therebetween into alignment with the I-beams with lifting hooks which engage the ribs while standing on the previously laid deck.
Claims19
An ergonomic method for transporting and installing sheets of metal decking in a composite floor or roof structure having underlying I-beams, said method comprising:
- loading a next sheet of metal decking on a carrier with a plurality of spaced apart ball rollers on an underside, a flat surface on an upper side for supporting the next sheet of metal decking and an inclined surface on a forward side, said next sheet of metal decking having a plurality of longitudinally oriented hollow ribs disposed in generally parallel spaced relationship with a flat panel section disposed between adjacent ribs;
- pushing the carrier across a previously laid deck until reaching an area where the next sheet of metal decking will be laid on the underlying I-beams;
- said spaced apart ball rollers on the underside of the carrier arranged such at any instant of time a number of the roller wheels are in contact with a plurality of the ribs while the other rollers remain free from entering into the flat panel sections;
- placing the next sheet of metal decking on the inclined surface with first and second lifting hooks working from opposite sides of the carrier;
- and,
- continuing to work from the previously laid deck while sliding the next sheet of metal decking down the inclined surface into place in the area where the next sheet of metal decking will be laid with the first and second lifting hooks in engagement with the ribs of the metal decking.
An ergonomic method for transporting and installing sheets of metal decking in a composite floor or roof structure having underlying I-beams, said method comprising:
- loading a next sheet of metal decking on a quadrilateral carrier with a plurality of spaced apart ball rollers on an underside, a flat surface on an upper side for supporting the next sheet of metal decking and opposing triangular shoulders on opposing vertices, each opposing triangular shoulder having a downwardly inclined surface, said next sheet of metal decking having a plurality of longitudinally oriented hollow ribs disposed in generally parallel spaced relationship with a flat panel section disposed between adjacent ribs;
- pushing the carrier across a previously laid deck with one of the opposing triangular shoulders facing forward until reaching an area where the next sheet of metal decking will be laid on the underlying I-beams;
- said spaced apart ball rollers on the underside of the carrier arranged such at any instant of time a number of the roller wheels are in contact with a plurality of the ribs while the other rollers remain free from entering into the flat panel sections;
- placing the next sheet of metal decking on the inclined surface of the one of the opposing triangular shoulders facing forward with first and second lifting hooks working from opposite sides of the carrier;
- and,
- continuing to work from the previously laid deck while sliding the next sheet of metal decking down the inclined surface into place in the area where the next sheet of metal decking will be laid with the first and second lifting hooks in engagement with the ribs of the metal decking.
