How to choose and use forged scaffolding fasteners?

Forged scaffolding fasteners are commonly used connecting components in construction, used to connect components such as steel pipes and crossbars of scaffolding frames. How to choose and use scaffolding fasteners correctly is an important link to ensure construction safety and quality.

At first, when selecting scaffolding fasteners, the following aspects need to be considered:

Choose durable materials: Common materials for scaffolding fasteners include cast iron, steel, and aluminum alloy. Cast iron materials have high durability and strength, but are relatively heavy; Steel materials have high strength and durability, with moderate weight; Aluminum alloy material is lightweight and suitable for high-altitude operations. Choose appropriate materials based on specific needs.

Pay attention to product standards: Scaffold fasteners should comply with relevant national standards, such as GB/T 21086-2007 "Fasteners for Scaffold Connections" or EN 74. Product standards ensure the quality and performance of fasteners, which is crucial for construction safety.

Consider load-bearing capacity: Select fasteners with load-bearing capacity that meets the requirements for using scaffolding. In general, the load-bearing capacity of scaffold fasteners is required to be no less than 20kN to ensure stability and safety during the construction process.

Choose the appropriate connection method: Scaffold fasteners have different shapes and connection methods, such as double insertion, docking, and breakage. Choose the appropriate connection method according to specific needs to ensure secure and reliable connections.

When using scaffolding fasteners correctly, the following points should be noted:

Pre use inspection: Before use, check whether the scaffolding fasteners are damaged or deformed to ensure their integrity and normal function. If there is any damage or deformation, it should be replaced in a timely manner.

Correct insertion: When inserting the fastener into the scaffold steel pipe, ensure that the depth of the fastener insertion meets the requirements. When inserting, the force should be evenly applied to ensure a tight connection between the fastener and the steel pipe.

Fixed fastening: After inserting the fastener, use tools such as a wrench or torque wrench to secure the fastener tightly, ensuring a secure connection between the fastener and the steel pipe. Do not use too much or too little force to avoid affecting the normal use of fasteners and causing safety hazards.

Regular inspection: During the use of scaffolding, the connection of scaffolding fasteners should be regularly checked for looseness or deformation, and adjustments or replacements should be made in a timely manner. At the same time, it is necessary to promptly clean the debris and corrosive substances on the fasteners to ensure their normal operation.
