Decking pallet
First Claim
1. A decking pallet for use in decking a transportable girder bridge of a type constructed form girder sections connected end to end to form two parallel trackways, which trackways are conjointly decked with a series of transverse decking units each having two ends respectively engageable with the two trackways, said girder sections including a series of locating recesses longitudinally spaced apart along upper edges of the girder sections and each of said decking units being provided at each of the said two ends with a hooked locating flange respectively engageable in a confronted pair of the said locating recesses in the two parallel trackways, and further having a through bore extending adjacent each of the two said ends in the longitudinal direction of the trackways, wherein the pallet comprises:
- a plurality of said decking units serially disposed with their through bores aligned so as to form two parallel channels,a tiebar disposed throughout each channel havng two ends extending beyond each of the two outermost units respectively,an annular spacer disposed interjacent each sequential pair of decking units and circumjacent each tiebar, the spacer being axially dimensioned so as to provide that the longitudial separation of the locating flanges of the decking units is in accordance with the longitudinal separation of the locating recesses in the girder sections, anda slinging means attached to each of the said ends of the two tiebars so as to be retractable below deck level.

3. A method of decking a transportable girder bridge of a type constructed from girder sections connected end to end to form two parallel trackways, which trackways are conjointly decked with a series of transverse decking units each having two ends engageable with the two trackways respectively, said girder sections being provided with a series of locating recesses longitudinally spaced along their upper edges and each of said decking units being provided at each of the said two ends with a hooked locating flange respectively engageable in a confronted pair of said locating recesses in the two parallel trackways, and further having a through bore extending adjacent each of the two said ends in the longitudinal directions of the trackways, wherein the method comprises the steps of:
-
(a) serially predisposing a plurality of said decking units with their through bores aligned so as to form two parallel channels, (b) disposing annular spacers interjacent each sequential pair of decking units in alignment with each of said channels, the spacers being axially dimensioned so as to provide that the longitudinal separation of the locating flanges of the decking units is in accordance with the longitudinal separation of the locating recesses in the girder sections, (c) inserting a tiebar through each channel and the predisposed annular spacers so as to form a pallet, the tiebar having two ends extending beyond each of the two outermost decking units respectively, (d) attaching a slinging means to each of the said ends of the two tiebars so as to be retractable below deck level, and (e) lifting the conjoined plurality of decking units onto the trackways by the slinging means so as to locate and engage all of the said locating flanges conjointly into the respective locating recesses of the girder sections.
