Halfen Channel
• No risk of damaging concrete due to
hammer drilling• No damage to reinforcement
• No problems with oversized or shallow
holes
• No dust or noise from drilling• No waiting for chemical anchor resin to
harden
• No need for power supply
• Very fast and easy to install• Can be cast in close to concrete edges
• Multiple fixings possible at close spacing
• Reduced installation time for subsequent fixings
Advantages of cast-in channels

Halfen HDB punching shear
Why do you need punching shear reinforcement ?
![Page 19: Halfen Fixings Presentation - ASELB 23-10-15.ppt](https://reader030.vdocuments.site/reader030/viewer/2022020707/61fd7ecd97dbac0b914801e4/html5/thumbnails/19.jpg)
Halfen HDB punching shear
• Faster to install than links
• Easy visual inspection

Halfen HBS Couplers
It is easy to check the completed
connection for correct safe fitting
Can be fitted without torque wrench
Due to its slender shape increased
concrete cover and reduced
congestion
CARES approvals for normal
construction and Sellafield nuclear
approval

CRET Shear System
More efficient shear load transfer across
the movement joint than a simple dowel
Vertical anchor rods and support box
activate the maximum amount of the
slab
Fewer columns are required
More floor space gained
CRET
for longitudinal movement onlyCRET-V
for longitudinal and lateral movement

• The bracket gives horizontal
and vertical adjustment
• Bracket can be bolted, the
façade can be completed
and the balconies bolted on
at a later date if required
