Abstract:
A roof decking membrane welding system, comprising:a roof decking substructure assembly; a first roof decking membrane disposed atop said roof decking substructure for protecting said roof decking substructure from environmental conditions; a second roof decking membrane disposed atop said roof decking substructure for protecting said roof decking substructure from environmental conditions, said first and second roof decking membranes having first and second portions, respectively, which are adapted to be mated together so as to form a seamed connection whereby said first and second roof decking membranes together provide continuous protection for said roof decking substructure against environmental conditions; a hold-down structure for engaging a portion of said first roof decking membrane for securing said first roof decking membrane to said roof decking substructure; and a fastener engaged with said hold-down structure and fixedly secured within said roof decking substructure so as to secure said hold-down structure upon said roof decking substructure; said first roof decking membrane comprising a section which is folded and secured with respect to itself such that when uplifting wind load forces act upon said first and second roof decking membranes, through means of said seamed connection, at least two sections of said first membrane will together operatively engage said hold-down structure and exhibit load-sharing reactive forces for resisting said up-lifting wind load forces.
