RESARCH AND DEVELOPMENT
최소한의 불행을 겪으면서, 가장 큰 행복을 얻는 방법은 작은 것을 관찰함으로써 얻을 수 있습니다.

아침에 여유롭게 내려 마시는 고소한 커피, 퇴근길 전철에서 내다보이는 석양을 바라보며 감상에 잠기는 일, 스삭거리는 포근한 이불과 함께하는 예정 없는 주말아침

FEATURE

    ▪ The accuracy of anchor pre-tensioning often involves a degree of uncertainty.
    ▪Pre-tension in operational anchor changes over time due to natural causes including ground relaxation and settlements and vibration & dynamic loads.
    ▪iPlate enables the utilization of sensor-equipped systems that continuously measure and report pretension, leading to more efficient maintenance processes.
▪iPlate enables remote inspections and alerts thorough user-friendly dashboards & graphs

FULL SCALE TEST

  • 1. Selective Concrete Cover Removal
  • – Remove existing cover concrete where required to expose the substrate.
  • 2. Anchorage & Bolt System Installation
  • – Install anchorage plates and set/consolidate concrete bolts for tendon bearing.
    3. Tendon Placement & Tensioning
  • – Position steel strands (tendons), grease/grout ducts, then jack to the specified prestress level.
    4. Shotcrete Overlay Application
  • – Apply a 5–10 cm layer of shotcrete (UHPC-compatible if desired) over the tensioned strands.
    5. Strand Release & Anchorage Removal
  • – Cut or release prestressing strands and dismantle temporary anchorage hardware.
