Construction steps
Mechanical fixation method:
base layer cleaning → laying air insulation layer → laying insulation board → pre-laying coil → fixed coil → lap treatment → node strengthening → self-inspection and acceptance
Full adhesion method: base layer cleaning → pre-laid coil → Large surface gluing → Laying coil → lap treatment → node strengthening → Closing treatment → Self-inspection and acceptance
Empty laying method: base layer cleaning → pre-laid coil → lap treatment → node reinforcement → self-inspection and receipt
