Steel column provided with thick plates, special-shaped skew bracket and truss layer and manufacturing method of steel column

Abstract

The invention relates to a steel column provided with thick plates, a special-shaped skew bracket and a truss layer. The steel column is characterized by mainly comprising a steel column body formed by sequentially connecting a moderate thick plate box type column subsection, a first thick plate box type transition section, an ultra-thick plate box type column subsection and a second thick plate box type transition section, an H-shaped skew bracket is mounted on one side of the moderate thick plate box type column subsection, a bracket shaped like a Chinese character ya is arranged on one side of the ultra-thick plate box type column subsection, an H-shaped straight bracket is arranged at the bottom of the ultra-thick plate box type column subsection, the special-shaped skew bracket is arranged above the ultra-thick plate box type column subsection, and an upper wing plate and a lower wing plate of the special-shaped skew bracket are special-shaped, are bent twice in the same direction by 1 degree, and form an included angle of 135 degrees with the steel column body. According to the high-efficiency and high-quality steel column provided with the thick plates, the special-shaped skew bracket and the truss layer and a manufacturing method of the steel column, the manufacturing difficulty of the complicated steel structure is reduced, and meanwhile, the technical blank of the structure in the field is filled up.

Description

technical field [0001] The invention relates to the technical field of steel structure production, in particular to a thick-plate special-shaped oblique corbel truss layer steel column and a production method thereof. Background technique [0002] The Shenzhen Ping An Financial Center project is a comprehensive large-scale super high-rise building mainly composed of Grade A office buildings, integrating shopping, sightseeing, catering and entertainment. The tower has 118 floors, the height of the main structure is 558.45 meters, and the height of the spire is 660.00 meters. The main structure is divided into tower and podium structures. The outer frame tube structure is composed of 8 giant columns, 7 ring trusses, giant supports and floor beams. The core tube adopts the lower steel plate shear wall, and the upper part is the stiff steel column shear wall. , the outer frame tube and the core tube are connected by four outrigger trusses to form an overall giant frame-core tub...
