Coupler is an essential part of post tensioning where a continuous tendon is laid over a few spans of girders in bridge construction. Due to the frictional loses that occurs during stressing, Couplers are used to provide optimum prestressing efficiency. TMG offers a few types of Couplers for different usage.
post-tensioning for strengthening of structures are diverse and only limited by imagination. Post-tensioned systems have large active forces and only knowledgeable and experienced personnel should be involved in the execution of repairs, modifications, and strengthening.

The system apply to the two-chip BJM15-J, it can be used for ring anchorage, flat anchorage, but also used for porous coupler. Anchorage ring Anchor ring is the key part of bearing the Prestressing tension. The ring anchorage is made by 45# high-quality carbon construction steel, and the flat anchorage is made by 40Cr steel.
When bonded multistrand post-tensioning systems are used for large structural members, such as beams and transfer girders, design advantages include increased span lengths and load-carrying capacity and reduced deflection. Additionally, because the strands are stressed simultaneously,
Bonded Strand Post-Tensioning System. Coupler R (Fixed Coupler) Coupler R is designed to couple on to already installed and stressed tendons. The coupler consists of a multiplane anchor body and a coupler wedge plate where the strands are overlapped. The continuing strands can be installed easily and independently.

coupling anchorage has been developed and improved, covering the full range of post-tensioning tendons. MTAIE external post-tensioning anchorage MTAID electrically insulated anchorage, widely used and tested in the world’s biggest full scale application, the 4,3 km long Piacenza viaduct. The production also includes the ST series
post-tensioning tendon which is elongated and anchored to provide the necessary permanent pre-stressing force. Segment — A precast element made out of concrete, with or with-out reinforcement, prestressed or non-prestressed. Sheathing or Duct — Enclosure around the prestressing steel. Tendon — The complete assem-bly for post-tensioning, consisting
Hilti HDI+ and HDI-P drop-in anchors with automatic setting tool take productivity and reliability to the next level for rod hanging applications in post-tension slabs, hollow core panels and precast planks.

Cast-in-place or post-installed, no other brand gives you more versatility, flexibility or productivity than Hilti. And when you pair Hilti anchors with specially matched installation tools and accessories, you can multiply your efficiency over every anchor point you install.
It consists of Anchor, Casting, Wedge and Bursting Reinforcement. It is most commonly found in bonded post tensioning using PC strand as tendons in prestressed concrete structure and rock/soil anchoring structure. TMG Stress Anchors ranges from 1 to 55 strands, with PC strand size of 9.53mm to 21.80mm.
VSL post-tensioning systems use a unique system for anchoring the prestressing force. The strands always remain in contact with the anchoring wedges during the stressing operation. As the pressure in the press is released, the strands are automatically locked in the conical holes of the anchor head.
Post-tensioning may conveniently be divided into cat-e g o ri e s, depending on whether the stressing tendon is on either an anchor or a coupler. A bar tendon assembly The anchorage ring con-tains concrete tensile bursting forc e s . Fi g u r e 4 shows a plate anchorage and a threaded coupling
