HBT - Rebend Connections

• Standard element lengths: 1.25 m and 0.80 m; other lengths on request
• 7 different profiles for connecting wall elements with a thickness starting from 6 cm
• 3 different rebar shapes available for one and two layer connections
• Rebar diameter: 8 - 10 - 12 mm
• Rebar: B500B, Stainless steel B500B NR available (on request)
• Bending diameter on the rebending point dBR = 6 × Ø

Casing heights:

• h = 24 mm for 8 mm diameter bars,
• h = 30 mm for 10 mm diameter bars,
• h = 36 mm for 12 mm diameter bars

Simple design approach according to the approval with only two basic required calculations:

• Loads perpendicular to the joint
• Loads parallel to the joint

Transfer of shear forces perpendicular and parallel to the joint with standard case

Proof of combined shear forces perpendicular and parallel to the joint possible

Standard version for constructional as well as for structural connections – no confusion on the construction site or in the precast plant

Steel casing with corrugated back for optimum transfer of shear loads in the jointProfile and cover made of galvanized steel to prevent corrosion - no plastic is left in the concrete

The special profiled edge prevents unwanted ingress of fresh concrete

Simple nailing or adhesion to the formwork

Dimensional stability during concreting due to the stable steel profiles and steel cover

Pre-cut hole allows for quick and easy removal of the cover after stripping the formwork

Low profile casing to ensure minimal concrete cover on the longitudinal sides

• For the construction of reinforced concrete structures where different stages of the pouring of structures are necessary, as well as in the absence of the possibility of organizing releases of reinforcement. For the most common installation situations there is a standardised product range for one and two layer connections with casing lengths of 0.8 m and 1.25 m. HBT Rebend connections are type tested and approved by the DIBt.
