Design of plank gratings
|

 |
A PcP. plank grating consists of a number of U-shape plank elements where the plank width depends on the load capacity requirement of the finished grating. Whereas the plank length depends on the required span in the support direction. The plank grating is joined with two edging bars that are welded onto the grating ends, at right angles to the span direction. The individual plank elements are welded together with a number of stitch weldings so as to make the grating a stable unit. The stitch welds are usually placed on the lower surface of the grating so that the upper surface appears as an unbroken series of planks with no unsightly welds. Moreover, the position of the stitch welds have been selected so that they transfer the load from the loaded plank to the neighbouring planks. As the plank gratings are built up by individual plank elements from a large program of different plank widths, this makes it extremely flexible to fit any project requirements.  |
