ติดตั้ง (Erection)

ติดตั้งโดยทีมงานติดตั้งที่มีประสบการณ์และควบคุมงานโดยวิศวกรโยธาที่ได้รับการรับรองจากสภาวิศวกร จึงมั่นใจได้ว่าอาคารโครงสร้างเหล็กสำเร็จรูป มีความแข็งแรง ปลอดภัย ภายใต้มาตรฐานทางวิศวกรรมที่ถูกต้อง

General Rules

  • Build column combing with purlins (if any), brace column together. Then, continue building rafters after adjusting column.
  • Install the inside truss frames, and then proceed to erect the outside ones (according to the movement of truck crane – see the enclosed construction drawing).
  • Begin erecting from the braced bay.
  • Settle two construction frames at the braced position before placing new frame. This process is translated for the next frame.
  • Have to have temporary brace during the erection process. Use purlins with the bracing cable to locate, and link all the rafter frames.
  • Erect steel panel after adjusting rafter frame and straight purlin, clean up, and paint all scratches on the rafter and purlin.
  • Use chalks or stretch attached wires to locate or mark axis positions in order to balance the steel panel when to complete the covering.
  • Set foot on the bottom waves when walking on the roof. Steel panel may be crashed if stepping on the high waves, which can cause deformation or leaking.
  • Do not walk on bright panels.

Erection Steps

STEP 1: PREPARE BEFORE ERECTION

STEP 2: ERECT COLUMN

STEP 3: ERECT RAFTER

STEP 4: ERECT PURLIN AND BRACE

STEP 5: WHOLE INSTALLATION TRUSS FRAMES AND PURLIN

STEP 6: ERECT RAFTER GABLE

  1. Place the end column and intermediate column at 1 axial
  2. Adjust alignment, position, elevation
  3. Tighten the entire anchor bolt
  4. Erect the first gable girder and endwall post
  5. Repeat step 4 for the remaining girder beam

STEP 7: COMPLETE PURLIN

  1. Install the entire truss bar, purlin, anti-purlin for two backside
  2. Install the entire perpendicular bracing of the pole and beam for the lock
  3. Keep these braces in a liquid state (not stretched)
  4. Adjust the beam girder
  5. Tighten the tie permanently.
  6. Remove all temporary truss of the building.
  7. Check and verify all connections, ensuring all bolts are fitted. All high strength bolts (structural bolts) must be tightened to the required tension
  8. Final inspection of the frame: correct ground plane and vertical

STEP 8: PULL PANELING ROOF

STEP 9: ROOFING IRON

  1. Install the rope safety cable system
  2. Preparing the construction electricity system
  3. Prepare construction scaffold system
  4. Installation of the first sheet of roofing

STEP 10: ERECT COVERRING AND FINISH

  1. Prepare construction scaffold system
  2. Mounting the entire sidewall girts, anti-purlin between the frame columns
  3. Install the entire wall panel
  4. Install gutters, ridge ventilator, beam, etc.
