Benefits
- Fast and efficient positioning of precast elements
- Screw connection allows easy, safe and fast on-site installation
- The connection can be subjected to load immediately after installation
- Transmission of tensile and transverse forces
- Full adjustability of precast elements also compensates for any imperfections in components
- No temporary bracing
- Erection independent from weather
- Quick installation and erection and therefore lower costs
- All applications feasible with one precast coupler type
- No special tools required
- Durable corrosion protection
Applications
- HEK Precast couplers are suitable for permanent connection of precast concrete elements subjected to static and quasi-static loads in reinforced and non-reinforced concrete of class C20/25 to C50/60.
- The precast couplers are suitable for transfer and anchorage of tension and shear loads or a combination of both in cracked and in non-cracked concrete.
