Expandable dual tube scaffold hatch structure

In combination with a scaffold system having horizontal scaffold members and vertical scaffold members assembled into a frame, a scaffold deck access system comprising

• a double barrel scaffold horizontal member, a series of short scaffold boards, a series of long scaffold boards, a series of short horizontal members and a safety rail system,
• said double barrel scaffold horizontal member further comprising:
• an upper tube and a lower tube assembly joined in a vertical relationship, said upper tube having an interior and an exterior end, and an upper attachment member positioned on said exterior end, said lower tube assembly having an exterior and interior ends and a lower attachment member positioned on said exterior end of said lower tube assembly, where said exterior end of said bottom tube assembly is distal from said exterior end of said upper tube;
• said double barrel horizontal scaffold member being joined to said scaffold frame through said upper attachment member and said lower attachment member, and said series of short scaffold boards being positioned perpendicular to and between said upper tube and one of said horizontal scaffold members, said long scaffold boards being positioned parallel to said short scaffold boards and connecting from one of said horizontal members to a second opposing horizontal members, thereby defining a scaffold work surface with an access opening therethrough, and
• said safety rail system comprising:
• a vertical stub attached to the interior end of said upper tube;
• a short vertical scaffold member attached to said vertical stub;
• one or more short horizontal members joined between the short vertical scaffold member and opposing horizontal scaffold members.
