Quick-set, full-moment-lock, assemblable and nondestructively disassemblable, column and beam frame system

A full-moment, column/beam structural connection comprising

• a column having a side,
• column-mount interface structure welded to said side,
• a beam having an end,
• beam-mount interface structure welded to said end, and
• a gravity-seated, nondestructably-disconnectable, discontinuous, full-moment structural connection established between said interface structures;
• wherein said column-mount interface structure possesses an outer bearing face which lies in a first plane that slopes downwardly and outwardly away from said side, and an upwardly tapered, wedge-shaped cleat which projects outwardly as an island from said face, said beam-mount interface structure possesses an inner bearing face which lies in a second plane that substantially parallels the first plane of the outer face in the column-mount interface structure, and an angular socket complementary to said cleat and formed in said inner face, and said connection is defined with said bearing faces confrontingly engaging one another, and with said cleat received complementarily within said socket.
