Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0034] see Figure 1 to Figure 12 , taking the Tianhui Center project as an example, the office building structure of this project has three variable sections, and each variable section is retracted by 1300mm through two-story inclined columns. The integrated lifting operation platform 2 adopts the processing measure of pulling the frame inward. The cantilevered steel beam 1 is welded by channel steel with a length of 3.0m of the corresponding strength type according to the design requirements. The hoist 4 is connected between the floor 3 and the integrated lifting operation platform 2 to lift the integrated lifting operation platform 2. When the integrated lifting operation platform 2 climbs to the non-variable section, loosen the floor 3 at the non-variable section. The bolts for fixing the cantilevered steel beam 1 are fixedly connected to...
