HALFEN HBT Rebend connection
efficient connection of concrete elements
HALFEN HBT Rebend connections are used for efficient connection of
concrete components, which are concreted in different sections. The
casing is made of corrugated galvanized sheet steel with
pre-punched grip holes in the cover to allow easy removal from the
casing. It can be fixed to the formwork with nails or secured with
a tie wire to the reinforcement. With 57 combinations of rebar and
profile widths, a wide variety of optimal connections can be
realized for different applications. The elements are available
with concrete reinforcement steel in 8, 10 and 12 mm
diameters.
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.

Product benefits
- 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 joint
- Profile 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
Technical data; 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
- 13 different rebar shapes available for one and two layer connections
- Rebar diameter: 8 - 10 - 12 mm
- Rebar
a) B500B
b) Stainless steel B500B NR available (on request) - Bending diameter on the rebending point dBR = 6 × Ø
Quality features:
- Connection bars made of B500B
- Stainless steel available on request
- 7 different casings to suit wall thickness from 6-23 cm. Special types are available for thicker walls.
- 13 different rebar shapes are available for single or double layer connections
- Reduced casing heights; because of their reduced casing height, HBTs are ideal for slender concrete elements or precast concrete elements with minimal concrete cover.
- 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
