The inspection of scaffolding couplers usually includes the following items:
1. Visual Inspection: Check whether the surface of the scaffolding coupler has defects such as cracks, deformation, and rust; check whether the bolts and nuts have thread damage or other damage.
2. Mechanical Performance Inspection: This includes anti-slip performance, damage resistance, torsional stiffness, tensile performance, etc. These need to be tested using professional mechanical testing equipment.
3. Dimension and Weight Inspection: In accordance with standard requirements, measure the main dimensions of the scaffolding coupler (such as thickness, width, height, etc.) and check whether its weight meets the specified standards.
4. Material Inspection: Analyze the chemical composition of the scaffolding coupler material to ensure the material complies with standard requirements.
5. Bolt Tightening Torque Inspection: For right-angle couplers and swivel couplers of scaffolding, it is necessary to test whether the torque of the bolts after tightening reaches the value specified in the standards.
The testing standards are mainly based on relevant national standards, such as Technical Code for Safety of Steel Tubular Scaffolding with Couplers in Construction (JGJ 130 - 2011) and Couplers for Steel Tubular Scaffolds (GB 15831 - 2016).
