When the space frame structure is installed, or a period of time after installation, the high-strength bolt sleeves of the space frame structure are loosened. There are many reasons for this situation, we need to analyze and deal with the specific situation:
1. Installation by undocumented workers: space frame workers have not received professional training, and they feel that they are tightening the sleeve. Many non-professional workers have not dealt with it well, and may not find the problem in time on the spot. However, it is very dangerous to loosen after a period of use.
2. After the roof panel was installed, the sleeve was loosened, the support was rusted, and the rod was damaged during use. These will seriously affect the carrying capacity of the space frame design, change the force structure, and cause hidden danger accidents.
For the above two problems, I personally suggest to stop using it and check and repair all aspects. In particular, each component of the space frame must be carefully checked and repaired in a targeted manner. The serious problems must be disassembled and reinstalled, and then repainted.
