The bolt ball steel space frame is composed of bolts, bolt balls, steel pipes, pins, sleeves, sealing plates or cone heads and other parts. The steel pipe rods and bolt balls are connected by high-strength bolts to form a space space frame structure .View more
When the entire roofing project is completed, the load loading is basically completed, the entire space frame is in a state of uniform stress, and the horizontal displacement of the space frame is basically completed.
The construction area of this project is 7770.77m 2, and the main body is frame structure. The roof truss space frame is divided into 2 groups, the size is 55.2×49.5m, the bolt ball joints, the square quadrangular pyramid bolt spherical space space frame structure, the space frame size is 3.3×5.45m, the thickness is 1.8-4m, and the top is supported by 36 supports The whole roof truss. The height of the space frame is 15.8m-22.13m, the total weight is 278t, the total number of nodes is 1092, and the total number of rods is 4160.View more
In order to prevent the grid frame from overturning as a whole, a support platform is built with heavy-duty steel pipe scaffolding. Each platform is covered with thickened scaffolding boards, and the support platform is set at the load-bearing node position of the support.View more
During the overall lifting and lowering process, in order to ensure that the entire building only moves in the vertical direction and does not allow horizontal displacement, a limit device is used to control the horizontal displacement.View more
