Embodiment 1

[0034] Example 1: Such as figure 1 A super-large composite H-section steel column shown includes two I-beams 2 and a connecting web 1; the two I-beams 2 are respectively installed on both sides of the connecting web 1, and the section after installation is H-shaped ; Connect the upper end surface of the web 1 and the I-beams 2 on both sides to form a concave structure, and a stiffening plate 3 is arranged along the concave structure, and a reinforcing rod 4 is arranged on the stiffening plate 3; corbels are installed on the side of the I-beam 2 5 and stud 6; two I-beams 2 are not arranged in parallel, and the angle between them is 1.5. The ultra-large composite H-section steel column is made of Q345GJC-Z25 steel plate with a size of 4050x2350x70x80mm.

[0035] The above-mentioned ultra-large composite H-section steel column is made by the following method:

[0036] (1) Use a 2,000-ton hydraulic press to level the I-beam and connecting webs, use a CNC straight cutting machi...

Abstract

The invention discloses an ultra-large type combined H-section steel column. The ultra-large type combined H-section steel column comprises two I-section steels and a connecting web; the two I-section steels are respectively arranged at two sides of the connecting web, and the section is of an H shape after installation; the upper end face of the connecting web and the I-section steels at two sides form a concave structure, a stiffening plate is arranged along the concave structure, and a reinforcing rod is arranged on the stiffening plate. Meanwhile, the invention further provides a manufacturing method of the steel column. According to the steel column and the manufacturing method thereof disclosed by the invention, when the bearing capacity of the post is ensured, the structure of the column is maximally simplified, raw materials are saved, the cost is saved, the manufacturing process is simple, the installation precision can be ensured, the effective usable area of a building is increased, the gravity of the structure is reduced, and the seismic response of the structure is decreased.

Description

technical field [0001] The invention relates to a steel structure and a manufacturing method of the steel structure, in particular to a super-large composite H-shaped section steel column and a manufacturing method thereof. Background technique [0002] Wuhan Greenland Center is located in the core area of ​​Wuchang Binjiang Business District, across the river from the century-old Bund of Hankou. It has a very advantageous geographical location and is a key area for the new round of urban development in Wuhan. Wuhan Greenland Center consists of a main tower, an auxiliary office building, an apartment building and a podium building. The main tower has 6 floors in the basement and 125 floors above the ground. It is a comprehensive building integrating office, exhibition, hotel, sightseeing, entertainment, commerce, etc. After completion, it will become a super high-rise landmark building in Wuhan. [0003] The tower frame adopts a structural system suitable for commercial sup...
