Putlog Coupler
• Standard specifications: Most are compatible with Ф48.3mm scaffold tubes, some are with Ф42mm, Ф51mm, that embodied by adjusting the screw bolt spacing.
• Flexible application: Used for temporary support and non-standard structures or fix diagonal braces for formwork system.
• Convenient operation: Single-sided fixation with bolt, simple operation and quick installation.
Product details
Putlog coupler is mainly used for the perpendicular connection between horizontal ledger and vertical standard of scaffolding system, or fix plank. The main body is of semi-circular arc shape and usually made of Q235 carbon steel, which has good strength and toughness. The surface is galvanized, which can effectively prevent rust and corrosion, and suitable for various construction environments.
Rigid connection of steel tubes | Fixation of component: Connect horizontal ledger and vertical standard, forming 90° perpendicular intersection and basic scaffold frame work. |
Fixation for plank: Connect plank with horizontal ledger and vertical standard, prevent shaking or falling off, provide stable working platform. | |
Act as tie-in member to walls or support points | In cantilever scaffolding: Putlog coupler connects cantilever beam with vertical standard as tie-in component to transfer horizontal loads (such as wind loads) and prevent the entire scaffold from overturning. |
In formwork support: Used to fix the bottom sweeper, horizontal tie rods, enhance the overall support rigidity and prevent deformation during concrete pouring. | |
Special construction scenario | Single-sided connection: Single-sided fixation avoid damage to opposite building in case of single-side structure required between scaffold and building, enjoy stronger adaptability. |
Temporary support construction: Can quickly build scaffold for pipeline installation or equipment maintenance, improve efficiency of emergency construction. |
