Problems solved by technology
In the traditional steelmaking plant design, the steelmaking plant tower is designed as a single-high span, and the installation process is relatively mature, but the steelmaking double-high-span tower structure has zero installation experience in China. The company previously worked in Ha Tinh, Vietnam. The steel project has experience in the installation of double-height span tower steelmaking plants, but the so-called double-height span steelmaking towers are relatively parallel, and the two towers are not connected, so the construction is basically carried out according to the conventional tower installation process. In this project, According to the conventional single-span steelmaking plant installation method, it is impossible to realize the double-height-span steelmaking tower installation, the main reason is that the double-height-span steelmaking towers are connected

Embodiment Construction
[0024] A double-high-span steelmaking tower installation method, comprising:
[0025] Step 1. Layout plan of double-height span towers (such as figure 1 shown);
[0026] Step 2. Introduction to the process of double-height span towers;
[0027] The 43m platform of the 1#2# high-span tower is connected to the second-section column of the 3#4# tower on the line 1 / 11-11 of the K column. Therefore, if the oxygen lance platform of the 10-14 line of the 1#2# high-span tower is to be completed , it is necessary to complete the two-section column of the 3#4# tower, but since the steel structure production volume of the double-high-span steelmaking plant has reached 85,000 tons, and the columns are all designed as box-shaped columns, the production volume cannot reach the double-high-span tower building at the same time Construction conditions, therefore, it is necessary to find out the best and reasonable double-height span tower installation process according to the steel structure...

The invention particularly relates to a double-high-span steel-making tower mounting method. The double-high-span steel-making tower mounting method is characterized by comprising the steps that a 1 #2 # tower high-span high-rise frame is constructed preferentially, wherein components are mounted in a modular mode, the mounting sequence adopts a positive mounting method, and the components are sequentially mounted from bottom to top; bottom layer columns are hoisted through a crawler crane, and adjustment and secondary grouting are conducted after the bottom layer columns are mounted; after the bottom layer columns are mounted, frame beams, bent frame beams and inter-column supporting mounting are conducted, platform secondary beams and iron alloy stock bins are assembled, and platform plates are sequentially mounted from bottom to top; tower high-span two-section columns are mounted; electromechanical tubes are synchronously inserted for mounting; and finally the crawler crane leavesthe field. Compared with a traditional single-high-span tower, modular assembly is adopted instead of traditional high-altitude splicing and mounting one by one, the shift cost of the crawler crane is saved, and the operation efficiency is improved.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a method for installing a double-high-span steelmaking tower. Background technique [0002] The steelmaking tower is the core of steelmaking, and a large number of equipment, pipelines, bridge cables are concentrated in the platforms of each floor of the tower. In the traditional steelmaking plant design, the steelmaking plant tower is designed as a single-high span, and the installation process is relatively mature, but the steelmaking double-high-span tower structure has zero installation experience in China. The company previously worked in Ha Tinh, Vietnam. The steel project has experience in the installation of double-height span tower steelmaking plants, but the so-called double-height span steelmaking towers are relatively parallel, and the two towers are not connected, so the construction is basically carried out according to the conventional tower installation proces...
