Space frame structure can be called spherical space frame or bolt ball space frame. It is connected by space frame rods and balls in a reasonable distribution to form a spherical space frame. Space frame structure is more suitable for large-span space, such as industrial plants, large coal sheds, gymnasiums, etc.
Then, for the safety control of space frame structure, the following quality control points need to be implemented!
- The material must meet the design requirements.
- The designed spherical space framemust meet the corresponding specifications and standards.
- Quality control of the assembly process.
- The unidirectional axial tensile and compressive bearing capacity test of the ball node and the parent material and other strong requirements.
- The bolt ball node conducts a tensile strength test on the thread of the largest bolt hole of the finished ball.
- The space frameinstallation should first control the construction and installation plan, and have a practical grasp.
- The reference axis and column top elevation must meet the design and standards.
- Focus on controlling the deflection value of the space frameunder deadweight and load. The average deflection value of the measuring point shall not be greater than 1.15 times the design value.
The above is a brief introduction to the space frame structure and its quality and safety control.
