PLATFORM ASSEMBLY-MONOLITHIC JOINT Russian patent published in 2017 - IPC E04B1/61 

FIELD: construction.

SUBSTANCE: platform assembly-monolithic joint comprises hollow-core flooring plates, arranged in the layout above adjacent rooms in mutually perpendicular directions, resting on the inner bearing wall panels; concrete diaphragms are arranged in the cavities of the flooring plates facing the plate butt, at a distance exceeding the panel thickness; the openings trapezoidal in the section are made on the entire plate thickness; the wall panels have openings, and therefore the upper zone of the panel is reinforced with a frame that has projections from the upper face plane of the panel on which the flooring plates rest; between the butts of the flooring plates, using these projections, the monolithic reinforced belt is arranged, the armature of which is connected to the vertical operating rods of the overlying panel and concreted. Also on the side faces of the flooring slabs there are recesses of the trapezoidal shape (dowels, grooves) which after laying in the space between the slabs of the flat reinforcing frame and filling them with concrete connect adjacent slabs to each other and form an assembly-monolithic horizontal hard disc of flooring.

EFFECT: rigid joint between the wall panels with openings by height and the formation of an assembly-monolithic horizontal hard disc of flooring when erecting panel buildings in seismically hazardous areas with the increase in the resistance of these buildings to progressive collapse.
