COMAX® P

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

COMAX® Q

  • 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
