COMBINED JOINT OF GIRDERS AND COLUMNS Russian patent published in 2015 - IPC E04B1/38 E04B1/20 

FIELD: machine building.

SUBSTANCE: in the combined joint the above located column and below located column, load-carrying reinforced-concrete girders and bracing reinforced-concrete girders are connected. In the vertical pockets if the below located column the carrying reinforced-concrete girders are installed by their support parts without flanges. On the end plate of the same column in direction perpendicular to the carrying girders the bracing girders are installed by their support parts without flanges. The reinforcements are welded with the embedded parts of the bracing girders. On the carrying girder from one side the hollow-core ceiling slabs are installed, at that the reinforcement projections of the carrying girder are located against pockets of the ceiling slabs. Via eyes of the reinforcement projections the reinforcement frameworks are inserted in the pockets of the ceiling slabs. Two reinforcement rods are installed on the reinforcement frameworks between ends of the hollow-core ceiling slabs, they are located along the carrying girders and above them.

EFFECT: increased reliability of the joint under loads, including seismic effects.
