In scaffolding, couplers are connectors that are used to join steel tubes together in a tube and fitting system. They play a crucial role in creating a secure and stable scaffolding structure. Couplers are typically made of steel and come in various designs, with each type serving a specific purpose. Some common types of scaffolding couplers include:
1. Double Coupler: This type of coupler is used to connect two scaffolding tubes at right angles to each other, forming a rigid joint.
2. Swivel Coupler: Swivel couplers allow two scaffolding tubes to be connected at any desired angle. They provide flexibility in creating different configurations and adapting to irregular structures.
3. Sleeve Coupler: Sleeve couplers are used to join two scaffolding tubes end-to-end, creating a longer span. They are commonly used when longer horizontal members are required.
4. Putlog Coupler: Putlog couplers are used to connect scaffolding tubes to the face of a wall or other structure, acting as a support for scaffold boards or planks.
5. Gravlock Girder Coupler: This type of coupler is designed to connect scaffolding tubes to steel girders or beams, providing a secure connection between the two elements.
The selection of couplers depends on the specific requirements of the scaffolding structure and the intended use. It is important to ensure that the couplers are properly installed and tightened to ensure the stability and safety of the scaffolding system.
