It will be appreciated that prior to construction of the steel structure building 200, the steel structure building 200 is divided into the first building module 210 and the second building module 220 to facilitate production of the first building module 210 and the second building module 220 to enhance the production of the steel structure building 200. The first building module 210 at least comprises two planes of a roof 211 and a top 212, the second building module 220 at least comprises two floor planes lower than the top 212, the first building module and the second building module are connected to form the steel structure building 200, and the multi-floor building is converted into a repeated connection process of the first building module 210 and the second building module 220, so that the building process of the steel structure building 200 is simplified, and the production efficiency of the steel structure building 200 is improved. Meanwhile, the first building module 210 and the second building module 220 at least comprise two floor surfaces, so that the influence of the lower stability on the steel structure building 200 during the assembly process during the conveying or lifting process of a single floor surface can be avoided, and the structural stability of the steel structure building 200 after the assembly is finished is improved. Of course, the first building module 210 and the second building module 220 may also be three floors or more, and need to be selected for different steel structure buildings, which is not described herein again.
Lifting the first building module 210 with the hydraulic lifting device 100; lifting the second building module 220 to the bottom of the first building module 210 using the hydraulic lifting device 100; fixedly attaching the second building module 220 to the bottom of the first building module 210; the second building module 220 is repeatedly lifted and fixedly connected to the bottom of the previous second building module 220 by using the hydraulic lifting device 100 until the number of floors meets the requirements of the steel structure building 200.
