Description

Technical Field

[0001] The utility model relates to the technical field of connection strength testing, in particular to a scaffold connection strength testing component. Background Art

[0002] Scaffolding is a common tool used in construction projects. Steel pipes are connected through cross clamps to form joints, forming a complete scaffold. The strength of the joints directly affects the scaffold's stability and the safety of construction workers. As a critical temporary support structure, the strength of the scaffolding's joints is directly related to the safety and stability of the construction process. Testing and evaluating the strength of scaffolding joints is often necessary during installation and load-bearing.

[0003] Traditional scaffolding connection strength testing methods often rely on manual inspection and experience judgment. The scaffolding connection strength is tested manually and visually. Usually, the detection accuracy is relatively insufficient, the subjectivity is relatively strong, and the safety is not good enough. The test equipment is usually large-scale equipment and needs to be installed inside the equipment before the scaffolding is installed to perform strength testing. It is relatively inappropriate for portability and cannot perform random convenience testing during the scaffolding installation process. The test convenience is not good enough, and the practicality and adaptability are insufficient. It is also impossible to perform lateral and torsional connection strength tests at the same time. The test convenience is insufficient and the safety is not good enough. For this reason, we propose a scaffolding connection strength testing component to solve the above problems.
