METHOD FOR ERECTING LARGE-SPAN MONOLITHIC REINFORCED CONCRETE FLOORINGS Russian patent published in 2017 - IPC E04B5/19 E04B5/10 E04B1/30 

FIELD: construction.

SUBSTANCE: wall of each I-beam is made corrugated, and its flanges are made of different sizes. The upper flange of each beam is made with a width less than the bottom flange width, the permanent formwork is made as a set of individual formwork elements, each of which is made in the section in the form of an open trapezoid with a top and a bottom base of a height "h" equal to 0.8 -0.9 "H1" of the I-beam height, but not less than 1/30 of the flooring span, and is placed on the lower flanges of the beams alternately, connecting them together. They are made of two segments connected overlapped when being laid on the bottom flanges of the beams, and said segments are fastened to one another, and the ends of each formwork element of the permanent formwork, lying on the lower flanges of the beams, are fixed to the lower flanges of the beams.

EFFECT: creating a large-span flooring not requiring large labour costs, convenient in installation and having an increased carrying capacity, including due to the complete support of the permanent formwork on the lower I-beam flanges.
