On construction sites, different types of projects will choose scaffolding for different purposes. When building bridges, cup-hook scaffolding, and portal scaffolding are common choices; while the construction of the main structure uses more coupler scaffolding.
The working conditions of scaffolding are unique:
1. The load changes greatly and is difficult to predict.
2. The coupler connection node is semi-rigid, and its rigidity is affected by the quality of the coupler and the quality of installation, and varies greatly.
3. The structure and components of the scaffolding may have initial defects, such as bending and rust of the rods, and errors in the erection size.
4. The connection point with the wall also has a great influence on the constraint of the scaffolding.
Due to these characteristics, the research on scaffolding lacks systematic accumulation and statistical data and does not have the conditions for independent probabilistic analysis. Therefore, the design method is actually semi-probabilistic and semi-empirical. Meeting the structural requirements specified in the specifications is the basic condition for design calculations. In actual engineering, the safety and stability of scaffolding are crucial, and it is necessary to strictly follow the design specifications for construction and use.
