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 receipt
Empty topping method: base layer cleaning → pre-laid coil → lap treatment → node reinforcement → self-inspection → cover the topping
