The super high-rise non-ground oblique grid structure of the utility model is used as a load-bearing structure around high-rise and super high-rise buildings, and is used to bear the vertical force of the building's own structure and the horizontal force generated by wind and earthquake. Through the design of oblique grid structure, no matter whether the building bears horizontal load or vertical load, the internal forces on the oblique rods, that is, the first oblique rods 3 and multiple second oblique rods 4 are mainly axial force, shear force and bending moment. All are small, and all diagonal bars can be stressed at the same time, which can maximize the distribution of the load. The traditional frame column structure usually uses horizontal bars and vertical bars to form a frame structure. When the building is subjected to horizontal loads, the horizontal bars are subjected to axial pressure, while the vertical bars are subjected to lateral shear force. The same is true when the building is subjected to vertical loads. .
