(166) Referring to
(167) Referring to
(168) Referring to
(169) The magnitude of clamping force is proportional to the torque applied to Bolt 15. Using an easily attainable 50 ft.-lbs. of torque applied to the preferred embodiment of a Grade 5-13 bolt results in a clamping force in the range of 5,000-10,000 lbs. per Stringer Assembly.
(170) Dividing this clamping force by the number of contact points on Deck Boards results in forces exceeding what properly installed nails can provide. Thus, the clamping force provided by the Stringer Assembly provides superior security of Deck Boards than traditional nails can provide.
(171) As discussed earlier, eliminating nails eliminates the primary source of Deck Board splitting. Further, any preexisting splits in Deck Boards should be mitigated as Deck Boards are compressed by clamping forces.
(172) Disassembly of the Modular Pallet System can be easily achieved with no tools.
(173) Counterclockwise rotation of Bolt 15 translates Outer Channel 13 in relation to Inner Channel 14 until Spring Button Assembly 19 contacts end of slot 33 in Inner Channel 14. In this configuration, Deck Boards can be easily removed.
(174) To disassemble Stringer Assemblies, continued counterclockwise rotation allows removal of Bolt 15. Captive Nut 17 can be removed from Nut Plate 18. Removal of Bolt Plate 16, Nut Plate 18 and Spring Button Assembly 19 complete disassembly process.
(175) Assembly is achieved by reversing disassembly process.
