For faster execution of reinforcement joints

• Standard length 1.25 m, height of the box: 30 mm
• Significant advantages for the planner:
  Excellent concrete bonding owing to perforated beaded strip
• Significant advantages on the building site:
  COMAX^® P speeds up completion of shuttering owing to tear-off cover
  - no tools needed
• COMAX^® P - KOMO certified
• COMAX^® P - robust and very strong
• COMAX^® P is highly compatible with the BETOMAX^® injection system
• Practically no restriction of injected material
• DIN 1045-1 states that the load capacity utilization of casings must not exceed 80%

Agenda:
B = Type/strip width/element width
l  = Anchoring length
b = Stirrup width
h = Stirrup height
e = Stirrup spacing

• Standard length 1.25 m
• Toothing in longitudinal direction for optimal force transmission
• COMAX^® Q for exposure to shear forces vertical to the joint
• Significant advantages for planners: acc. to DIN 1045-1 the COMAX^® Q is classed as "TOOTHED"
• Dimensionally stable cover facilitates short striking times
• Special types (except K and BK) available on request

• Standard length 1.25 m
• Toothing in transverse direction for optimal force transmission
• COMAX^® L for exposure to longitudinal shear forces parrallel to the joint
• Significant advantages for planners:
  acc. to DIN 1045-1 the COMAX^® L is classed as "TOOTHED"
• Dimensionally stable cover facilitates short striking times
• Special types (except K and BK) available on request

• DIN 1045-1 states that the load capacity utilization of casings must not exceed 80%

PU magnet for securing COMAX^® to steel shuttering.Easily applied and removed thanks to screw thread.

Benefits:

• Extremely powerful magnet: 4 magnets per 1.25 m element, 6 magnets per 2.50 m element
• Special shape - with groove - exact fit for COMAX^® P
• Highly resistant: may be re-used up to ten times
• Easily employed - tools or aids not required. Removal with the help of the embedded screw thread.
• Suitable for pre-cast sections and construction sites
