Structural block assembly

A block assembly for connecting a first section to a second section of a load bearing assembly, wherein the first section includes a fitting attachment section including a first section flange and a fitting attachment channel, and wherein the second section includes a cavity surrounding a second section opening and a cavity lip positioned within the cavity, the block assembly comprising:

• a male fitting comprising:
• a male fitting body including a top portion and a bottom portion;
• a male fitting flange attached to said top portion of said male fitting body, wherein said male fitting flange is attachable to the first section flange to attach said male fitting to the first section of the load bearing assembly;
• a projection extending from said male fitting body;
• a female fitting comprising:
• a female fitting body including an upper portion and a lower portion and defining a fitting cavity extending within an interior of the female fitting;
• an interlocking joint defined in said female fitting body;
• a fitting base attached to the lower portion of said female fitting body, said fitting base including a female fitting lip;
• wherein said female fitting is configured to fit into the second section opening and wherein said female fitting lip is attachable to the cavity lip to attach said female fitting to the second section of the load bearing assembly;
• wherein said male fitting is configured to couple with said female fitting by inserting said male fitting body within said fitting cavity and moving said male fitting body toward the fitting base of the female fitting;
• wherein said projection interacts with the interlocking joint on said female fitting to resist detachment of said male fitting with respect to said female fitting;
• and
• wherein the upper portion of said female fitting body is configured to fit within the fitting attachment channel of the first section of the load bearing assembly when the first section and the second section are connected.
