NODAL COUPLING OF PILLAR WITH MONOLITHIC SLAB Russian patent published in 2015 - IPC E04B1/38 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular, to a nodal coupling of a pillar with a monolithic slab. The nodal coupling comprises meeting beams made with pre-stressed reinforcement, shelves of the slab and the pillar. Pre-stressed reinforcement bars are fixed in the pillar extension in the form of a hollow anchor device or in a contour of a metal shape taken out to the distance relative to walls of the anchor device installed perpendicularly to the reinforcement bars and attached to the anchor device by vertical sheet elements. Force reverse to tension is perceived by light trusses, besides, the truss at the bottom of the slab will provide for spacing between concreted pillars, and the truss on top is installed between anchor accessories. The anchor device by the lower end is rigidly concreted into the body of the pillar and is welded to the frame of the pillar; beams and the slab are simultaneously solidified at pours. Concreting is done from the bottom of the beams to the top of the slab. After concreting of the entire slab area the cavity of the anchor device that exits the pillar is concreted.

EFFECT: increased bearing capacity.
