From concept to installation: key points of the whole process design of bolt ball grid structure

      The bolt ball grid structure, as an ideal solution for large-span spatial structures, relies on precise control of the entire process from concept to installation to achieve its outstanding performance. The following is a systematic analysis of its core design points.

 

 

 

      During the project initiation phase, it is necessary to clarify the structural span, load, and building function. Based on this, professional software is used for 3D modeling to determine the mesh form (such as triangular pyramid, square pyramid) and member layout. The core of this stage lies in achieving a balance between structural efficiency and architectural aesthetics, and verifying the feasibility of the plan through preliminary calculations.

 

 

 

      This is the key to ensuring the quality of the project. It is necessary to perform three-dimensional coordinate positioning for each bolt ball node and complete precise cutting length calculation for each member. The design needs to comprehensively consider the deformation caused by weld shrinkage, prestress, etc., and preset a reasonable arch value. At the same time, complete the detailed design of nodes such as bolt ball screw hole angle and high-strength bolt specifications to ensure zero errors in factory prefabrication.

 

 

 

      The design party needs to provide a clear installation plan, usually using construction methods such as "high-altitude bulk" or "segmented lifting". The design drawings should include a complete construction sequence, temporary support points, and final scaffolding principles to effectively guide on-site operations, avoid irreversible additional stresses during installation, and ensure the safe formation of the structure.

 

      The systematic design of the entire process is the fundamental guarantee for the bolt ball truss structure to achieve its advantages of large span, high precision, and construction speed.
