HBS-05 - Screw Connections

The HALFEN HBS-05 screw connections are an optimum solution for all connections for reinforced concrete constructions. The HBS-05 screw connections can be used in any combination. Due to the versatility of the HBS-05, it can create almost every joint reinforcement. One and the same connection bars can be used for all female bars - whether it has a threaded socket or a forged design. The position socket enables the connection between axially unmovable and non-rotating bars, e.g. for crane openings in ceilings. HBS-05-end anchors are available for connections with short anchoring lengths.HALFEN HBS-05 meets national and international design standards. Extensive survey reports and test reports demonstrate their capability, even under extreme loads:

• High fatigue strength in bridge structures
• Cyclic alternating loads, even with heavy earthquakes
• Impact loads in nuclear power plants

The HALFEN HBS-05 screw connections guarantee planning reliability and high efficiency.
The use of high quality raw materials and the manufacturing quality at our certified production site ensure the consistently high level of safety and quality of HALFEN products.

High planning reliability thanks to:

• General building approval DIBt Z-1.5-189
• Approval for predominantly non static loads and high fatigue strength, e.g. for use in bridges or crane runways
• High ductility - HBS-05 Seismic meets the requirements of cyclic alternating stresses under seismic impacts or similar natural events
• International - numerous country-specific approvals, test reports and survey reports confirm their compliance with the design criteria of international standards
• Exceptional loading capacity - HBS-05 meets the high standards of exceptional loads, such as explosions or impact loads

Efficient and economical:

• No special tools and no torque wrench is needed to screw them in - just a simple visual inspection is sufficient
• An extensive range of accessories, socket bars and prefabricated formwork fasteners save you time during the installation, and guarantee a secure fixing to the formwork
• Colour-coded caps to clearly denote the assignment of the diameter

Quality features:

• extensive delivery programme bars with diameters ranging from 12 to 32 mm
• colour coding for easy assignment of system parts
• approved for dynamic loads acc. to DIN 1045-1 for bar diam. 12 to 28 mm
• forged socket bars can be nailed directly to the formwork
• bolted socket bars are particularly economic for vertical reinforcement connections and custom lengths
• official approved (DIBt Berlin) 
• safe installation with a simple visual check, no torque wrench necessary
• approved for “extraordinary load effects” such as explosion and impact loads in nuclear power plants
• HBS-05-Seismic: screw connection with the highest ductility, suitable for buildings in regions prone to earthquakes
