FIELD: construction.
SUBSTANCE: invention relates to construction, specifically to beam nodal joints. First, in main beam wall holes are made for each of two secondary beams bolted connection, and to belts of secondary beams by welding tubular profiles are connected for passage of bolts, which are installed on support elements welded in zone of holes, made in form of channel bar, distance between flanges of which is greater than diameter of tubular profile, after that, performing the two adjacent secondary beams tightening with the main beam wall by passing the bolts through the tubular profiles, secondary beam wall is bolted to main beam stiffness rib.
EFFECT: increasing the rigidity of the nodal connection of beams by absorbing significant bending moments and transverse forces.
