Threaded connection MAX FRANK Coupler
Mechanical connection and anchoring of rebars by means of threaded couplers for permanent and dynamic loading
The MAX FRANK threaded socket connections are used where the conventional splice joint is not practical or not permitted. They are also used where rebending is not possible due to the rebar diameter. The rebar connection usually consists of a threaded bar with a pre-mounted threaded coupler for the 1st construction phase as well as the continuation bar for screwing in during the 2nd construction phase. Threaded coupler connections offer an efficient and cost-effective way to connect reinforcing bars under permanent and dynamic loads.
Advantages
- Easy and quick installation
- Available for all common rebar diameters (12 to 40mm)
- 100 % force transmission – “Bar Break”
- No reduction in the rebar cross-section
- No positioning couplers required
- Designed to conform to international standards: Eurocode 2 (NEN/DIN/BS EN 1992-1-1), ACI 318 type 1-2,
test standard ISO 15835 - Numerous country-specific approvals available
Product variants
Threaded connection MAX FRANK Coupler standard connection
for freely rotatable coupler connections
The same threaded couplers are used for standard and positioning connections.
With the standard connection, a threaded rod is installed in the 1st construction phase; in the 2nd construction phase, the continuation bar is longitudinally movable and freely rotatable.
Threaded connection MAX FRANK Coupler positioning connection
for non-freely rotatable coupler connections
With the positioning connection, the continuation bar is longitudinally movable, but not rotatable.
Therefore, a protected threaded rod is initially installed in the 1st construction phase. In the 2nd construction phase, a threaded rod with a loosely screwed- on lock nut and pre-mounted threaded coupler is connected according to the work instructions. A special positioning coupler is not required.
Threaded connection MAX FRANK Coupler reducing connection
for force-locked connection of different steel diameters
Transition couplers are used to connect rebars with different diameters together.
Transition threaded couplers are frequently used for columns and cross-storey connections. Positioning connections can also be manufactured using transition couplers.
Threaded connection MAX FRANK Coupler weldable coupler
Connection of rebars using steel components
The weldable coupler offers an effective solution for connecting rebars together using steel components.
It is made of a weldable material and has a circumferential chamfer at one end for applying the welding seam. Like the other couplers, the weldable coupler has a metric thread and is available for all common rebar diameters.
Threaded connection MAX FRANK Coupler end anchor
Anchoring of rebars
End anchors or anchor plates are used for anchoring rebars.
End anchors are used if the required anchoring length of the rebar cannot be installed in the structure and end hooks cannot be used due to excessively congested reinforcement or overly thin components.
Threaded connection MAX FRANK Coupler product combinations
for high load-bearing capacity in the construction joint (indentation for shear force, indentation for thrust)
Product combinations with MAX FRANK Coupler threaded connections offer the advantage of the secure connection of rebars in a wide range of applications.
MAX FRANK Coupler connections are installed in prefabricated components in the factory for easy installation.
