Problems solved by technology
[0006] The purpose of the present invention is to overcome the unreasonable problem of steel column segmentation in the prior art, and provide a large-scale steel-making high-span solid-belly steel column and its installation method; the present invention divides the entire steel column into four sections reasonably, On the basis of ensuring the convenience of hoisting, reduce the number of installations between the columns and ensure the installation accuracy of the entire steel column; in addition, limit the mutual height between the lower column I and the lower column II at the bottom, and limit the height of each column Limit the length between them to reduce production costs while ensuring sufficient bearing capacity

Embodiment
[0052] combine figure 1 , a large-scale steelmaking high-span solid-web steel column in this embodiment includes a lower column double-leg solid-web unit and an upper column single-leg solid-web unit installed on the foundation 50 in sequence, and the lower column double-leg The solid belly unit is divided into lower column I10 and lower column II20; the upper column single-leg solid abdominal unit is divided into upper column III30 and upper column IV40, and the height of the lower column I10 is 1.25-1.35 times that of the lower column II20 , can be 1.25, 1.28, 1.30...1.33 or 1.35 times.
[0053] Preferably, the height of the lower column I10 in this embodiment is 1.26 times that of the lower column II20.
[0054] In addition, if figure 1 As shown, the lengths of the lower column I10 and the lower column II20 in this embodiment are equal, the length of the upper column III30 is 1 / 2 of the length of the lower column II20, and the length of the upper column IV40 is 1 / 2 of the...

The invention discloses a large-scale steelmaking high-span solid-web steel column and a mounting method thereof, and belongs to the technical field of factory building steel column mounting. According to the structural form, weight and length of the solid-web steel column and relevant parameters such as the rated lifting capacity of a crane, the steel column is reasonably manufactured in a segmented mode and divided into a lower column I, a lower column II, an upper column III and an upper column IV. The mounting process of the steel column comprises the steps that firstly, a foundation is retested, a base plate is arranged, after the lower column I is aligned to be qualified, foundation bolts are fastened, and then the lower column II is mounted; inter-column supports, frame beams and platform beams on a lower column double-limb solid-web unit are mounted; then grouting is conducted between the lower column I and the foundation; and the upper column III is mounted, the frame beams and the platform beams connected with the upper column III are mounted, and finally the upper column IV is mounted. The whole process is safe and reliable, the mounting efficiency and mounting precisionof the steel column are effectively improved, the mounting and welding procedures are conducted alternately, the mounting operation face is enlarged, the construction period is shortened, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of plant steel column installation, and more specifically relates to a large-scale steelmaking high-span solid-belly steel column and an installation method thereof. Background technique [0002] During the steel structure installation process of the existing large-scale steelmaking main workshop, the steelmaking converter spanning workshop is a multi-storey high-span frame structure, with many horizontal and vertical cross operations, high structural height, and a large amount of high-altitude operations. In order to ensure that the steel columns can have enough Therefore, in the actual production process, the steel column is generally divided into multiple sections. On the one hand, it is convenient to produce the entire steel column; on the other hand, the steel column is easy to hoist during the installation process. [0003] For example, Chinese patent number: ZL 201310397566.8, date of authorization an...
