The tightening sequence of high-strength bolts is to press the rod first and then pull the rod to prevent the rod from being pushed up when the tie rod is tightened first, resulting in the occurrence of bolt leakage.
The coal handling project includes two space frame spherical shells, the structure form and size of which are the same, the structure type is the bolt ball joints are placed square pyramid spherical space frame, the lower chord peripheral point support, the support adopts one-way sliding support, the support The span is 124.35 m.
In order to ensure the installation and quality of space frame and space frame bolt ball processing, all hollow steel ball nodes and steel pipe rods are processed centrally in the factory.
When the construction technology of large-span steel space frame membrane structure is applied, it must strictly follow the requirements of the existing quality assurance system, reasonably construct and utilize the quality assurance system that meets the requirements, and follow the basic principles of "quality management", to ensure that all aspects of the construction of the large-span steel space frame membrane structure can be carried out in an orderly manner, so as to provide a guarantee for the construction quality.
The application of large-span steel space frame membrane structure technology is not only conducive to reflecting the advantages and characteristics of the application of membrane structure construction technology, but also It can also ensure the improvement of construction quality, prevent the steel structure from being affected by different substances such as rainwater, and provide a guarantee for the stability and reliability of the steel structure.
