1. Use BIM technology to accurately complete the installation of the steel structure truss shed: Due to the large size of the steel truss shed roof in the photography warehouse, it is inconvenient to transport as a whole. It is assembled at one time, and the whole is hoisted. The construction environment of the project site is relatively complex, and the construction of the steel structure requires sufficient space for installation and hoisting. Due to the large size of the truss roof, the space for assembly and rotation in the shed is limited, and there is only 8 cm of operating space at the narrowest part and the main structure. , the installation technique is difficult, which puts forward high requirements for the operation accuracy of the crane and the cooperation of personnel.
2. The 5# photography warehouse has a total of 10 main trusses. The span of a single main truss is 60 meters and the weight is 60 tons. Two sets of 150-ton crawler cranes are used to lift and lift the height of 21.4 meters. At present, the main structure has been installed, and the installation progress is 70%.
3. The 16# photography warehouse has a total of 8 main trusses. The span of a single main truss is 45 meters and the weight is 32 tons. It is hoisted by a 200-ton crawler crane with a lifting height of 19.45 meters. At present, the main structure has been installed, and the installation progress is 90%.
4. The 17#photography warehouse has a total of 8 main trusses. The span of a single main truss is 45 meters and the weight is 32 tons. It is hoisted by a 200-ton crawler crane with a lifting height of 19.45 meters. At present, except for the slide rail beam that has not been installed yet, all other work has been completed, and the installation progress is 95%.
5. The 18# photography warehouse has a total of 4 main trusses. The span of a single main truss is 22.5 meters. It is hoisted by a 50-ton truck hoist with a lifting height of 13 meters. The shed installation work is now complete.
