How many quality control points need to be implemented for the safety control of the space frame structure?

 

space frame

1The material must meet the design requirements.

2The design of the spherical space frame must conform to the corresponding specification standards.

3The quality control of assembling process.

4The one-way axial tensile and compressive bearing capacity test of the ball node is as strong as the parent material requirements.

5Bolt ball node for the thread of the largest bolt hole of the finished ball for tensile strength test.

6The installation of the space frame should be the first control construction and installation program to have a practical grasp.

7The reference axis and the elevation of the top of the column must conform to the design and standards.

8, focus on controlling the deflection value of the space frame under self-weight and load, the average deflection value of the measurement point shall not be greater than 1,15 times the design value.
