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 present invention is specifically a kind of double-high-span steelmaking tower installation method; It is characterized in that: it includes the feature of: including the priority construction of 1#2# tower high-span high-rise frame; the components are installed in a modular manner, and the installation sequence adopts the formal installation method, from Install from bottom to top in sequence; use crawler cranes to hoist the bottom column, adjust the bottom column after installation, and perform secondary grouting; after the bottom column is installed, install frame beams, bent beams, and inter-column supports to platform secondary beams and ferroalloy materials Warehouse assembly and platform slabs are installed sequentially from bottom to top; the installation of the high-span two-section column of the tower is carried out; the electromechanical pipes are inserted synchronously for installation; finally, the crawler crane leaves the site. Compared with the traditional single-height span tower, this method adopts modular assembly instead of the traditional one-by-one splicing and installation at high altitude, which saves the shift fee of crawler cranes and improves the working efficiency.
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...
