Rebend connections

HALFEN Rebend connections

HALFEN Rebend connections are used for efficient connection of concrete components which are poured in different phases and then connected. The casing is made of corrugated galvanized steel sheet with pre-punched holes to allow easy removal of the cover. It can be fixed to the formwork with nails or secured with tie wire to the reinforcement.

HALFEN HBT Rebend connections

HALFEN HBT are type-tested and general building authority approved rebend connections. For the most common applications, a standardized product range is available for single and double row rebar connections, with box lengths of 0.8 m and 1.25 m and a combination of various reinforcement bar diameters and casing widths. Further design types are available on request.

Shear load in joints can be verified with a simplified design concept in accordance with the approval, with only two basic load cases:

Loads perpendicular to the joint
Loads parallel to the joint

A combination of rebar types and casing widths ensure the best connection for a wide range of applications. The elements are available with 8, 10 and 12 mm diameter. Special versions are available on request.
One standard version for constructional and for structurally relevant connections – no mix-ups on the construction site or in the precast plant
Steel casing with special corrugated back for optimum transfer of shear loads in the joint
Casing and cover made of galvanized steel to prevent corrosion - no plastic can be left in the concrete
The special shaped box edge prevents ingress of fresh concrete
Easy to nail or glue to the formwork
The strong casing keeps its shape during concreting
Pre-cut hole allows quick and easy removal of the cover after striking the formwork
Low profiled casing also ensures minimal concrete cover on the longitudinal edges of the casing

Standard element lengths: 1.25 m und 0.80 m, other lengths on request
7 different casing widths for connecting components with a thickness of 6 cm or higher
13 different rebar types available for single and double row connections
Rebar diameter
- Ø 8 mm
- Ø 10 mm
- Ø 12 mm
Rebar stirrups
a) B500B
b) Stainless steel B500B NR available (on request)
13 different stirrup shapes are available for single or double row connections
Reduced casing heights; because of their reduced casing height, HBTs are ideal for minimal thickness concrete elements or precast concrete elements with minimal concrete cover
Casing heights
h = 24 mm for rebar diameter Ø 8 mm
h = 30 mm for rebar diameter Ø 10 mm
h = 36 mm for rebar diameter Ø 12 mm
