Super high-rise industrial upstairs fabricated octagonal mesh cylinder structure and system and construction method

The invention provides a super high-rise industrial upstairs fabricated octagonal net cylinder structure and system and a construction method. The super high-rise industrial upstairs assembly type octagonal net cylinder structure comprises an assembly type regular octagonal open-web grid floor system, the open-web grid floor system comprises a plurality of isosceles triangle open-web grid units, eight side frames of the open-web grid floor system are formed by sequentially connecting a plurality of ring beams, the ring beams are supported by X-shaped inclined columns, and the X-shaped inclined columns are connected with the open-web grid units. Two top supporting legs of the X-shaped inclined column are respectively connected with the two ring beam connecting nodes; the isosceles triangle open-web grid units located in the non-frame area of the open-web grid floor system comprise upper ribs, lower ribs and ribbed shear keys, the ribbed shear keys comprise top plates, bottom plates and connecting steel columns
