Some special buildings need to adopt special construction technology, because it is a little difficult, for example, our super high-rise steel structure is the same, its construction is more complex, but also more troublesome, so how to do the construction technology of super high-rise steel structure?Let HJSD steel structure engineering company’s small editor to tell us about.

   Combined with the process flow and characteristics of high-rise steel structure (component acceptance → hoisting → high-strength bolt → welding and inspection → profiled steel plate and stud), the construction skills of super high-rise steel structure are summarized.The construction skills of super high-rise steel structure mainly include the following aspects: ① selection, placement and assembly and disassembly of tower crane; ② mobilization, acceptance and stacking of components; ③ hoisting; ④ measurement control; ⑤ welding; ⑥ construction period and quality control; and (7) safe construction.  

   The selection, placement, installation and disassembly of tower crane is the core equipment of super high-rise steel structure engineering construction. The requirements for the lifting ability and range of tower crane are not as strict as the selection of attached tower crane.In addition, the cost of the attached tower crane is much higher than that of the internal climbing tower crane which can be slightly smaller. For example, the design height of the project is 150m, and the tower body height of the attached tower crane is about 180m (considering the steel structure with 3-storey column of 12M, sling of 4-6m, hook pulley and trolley full height of 4m, safe operation distance of 2m, etc.), and the height of underground part is 200mThe body is about 40-50m.  

   The rental cost of attached tower crane is higher than that of internal climbing tower crane.Therefore, from the economic point of view, in order to save the cost, the internal climbing tower crane is preferred for the construction of steel structure super high-rise buildings. 

   Hoisting is the leading process of steel structure construction. The speed and quality of hoisting play an important role in the whole project.Before hoisting the steel structure, the hoisting division and hoisting sequence shall be determined according to the structural plane and elevation shape, structural form, number and orientation of tower crane, site construction conditions and other elements.
