Multiple Types of "Fastening" Tools in Construction Engineering - Coupler

The double coupler plays a crucial role in the steel pipe scaffold, which is mainly used to vertically cross connect two steel pipes to ensure the stability of the scaffold. When the longitudinal rod and the transverse pipe of the steel pipe scaffold need to be connected and fastened, the double coupler can play a key role. More importantly, it can effectively prevent the transverse pipe from sliding after external load when the bolt torque distance reaches 40n·m, so as to ensure the safety of construction personnel.



2. Application and characteristics of swivel coupler

The swivel coupler is designed for the joint fastening of two steel pipes at any Angle. It is often used for the scissors support of scaffolding and the double-sided column connection of steel pipe scaffolding in high-rise buildings. The fastener has the same torque distance as the double coupler to ensure the stability of the connection.



3. Application and characteristics of joint pin coupler

The joint pin coupler is designed for the butt joint of two steel pipes and is suitable for the joint length of vertical pipe, horizontal pipe and diagonal brace. Its clever design ensures a strong and efficient connection.




Various types of building couplers, specially designed for the construction project ф48mm steel scaffold, derrick, template support, etc., tighten the fulcrum and intersection point to ensure a stable connection. It also applies to water conservancy, chemical industry, metallurgy, mining, railway and other infrastructure projects.
