BS EN 74-1:2005

What is BS EN 74-1 - Couplers for scaffolding tubes about?

BS EN 74-1 is the first part of the BS EN 74 series that discusses couplers, spigot pins and baseplates for use in falsework and scaffolds.

BS EN 74-1 defines a set of steel and aluminium reference tubes for the required tests.

BS EN 74-1 specifies, right-angle couplers, swivel couplers, sleeve couplers and parallel couplers working by friction:

• Materials
• Design requirements
• Strength classes with different structural parameters including values for resistance and stiffness
• Test procedures
• Assessment

and gives recommendations for ongoing production control.

Who is BS EN 74-1 - Couplers for scaffolding tubes for?

BS EN 74-1 on couplers for tubes used in scaffolds is useful for:

• Manufacturers of hardware equipment
• Civil engineers
• Architects
• Real estate developers
• Construction project managers

Why should you use BS EN 74-1 - Couplers for scaffolding tubes?

Couplers are used to connect two tubes. For scaffolding tubes these couplers need to be well designed as any defects or discrepancies in the dimensions of these couplers could leave a tube unsecured and can potentially cause accidents.

BS EN 74-1 informs you about different types of couplers and classifies them based on their strength and values of resistance and stiffness. This helps you to select the appropriate coupler based on your requirements. BS EN 74-1 specifies performance parameters and verification methods for these couplers.

Overall, the guidelines of BS EN 74-1 enable you to produce couplers with enhanced gripping strength and durability.
