PLATFORM PREFABRICATED MONOLITHIC JOINT Russian patent published in 2025 - IPC E04B1/38 

FIELD: construction.

SUBSTANCE: invention relates to construction and is intended for device of platform joints. Platform prefabricated monolithic joint includes posts of overlying and underlying inverted U-shaped panels-frames, crossbars of inverted U-shaped and L-shaped frames, each of which is made of monolithic and prefabricated parts, and hollow-core floor slabs. In the lower part of the post of the overlying U-shaped panel-frame there is an opening for the entire height of the monolithic part of the crossbars. Longitudinal and transverse reinforcement rods protruding from the prefabricated part of the crossbars are covered with reinforcement outlets in the form of meshes protruding from the upper flange of the hollow-core floor slabs. Space between the ends of the floor slabs and the aperture in the post together with all the reinforcing elements is monolithic with concrete. Crossbars of two adjacent U-shaped and L-shaped panel-frames are connected by means of cantilever projection of L-shaped panel-frame and cutting of U-shaped panel-frame using embedded parts. Connection of the upper face of the post of the underlying U-shaped panel-frame and the lower face of the assembled part of the transom of the overlying U-shaped panel-frame is made using a double plug-in joint.

EFFECT: increased spatial rigidity.
