JOINT CONNECTION OF CROSS FRAMED STRUCTURES Russian patent published in 2013 - IPC E04B1/38 

FIELD: construction.

SUBSTANCE: joint connection of cross framed structures, comprising trihedral (trough-shaped) gusset plates with bolted overlapping fixtures at ends of tubular rods or dihedral (angular) gusset plates with bolted overlapping fixtures at ends of double-tee rods. Gusset plates of rods of one of directions are installed with shelves from inside the shelves of the gusset plates of rods of another direction. There are support tables placed between overlapping bolted shelves of gusset plates being mutually supported against each other. Under action of stretching forces the support tables are pairwise stiffly connected with shelves of gusset plates in zones of their wings, and under action of pressing forces - in zones of their picks.

EFFECT: increased bearing capacity and reliability of structures.
