Technical Disclosure for Wall Aluminum Honeycomb Panel Construction

1. Pre-Construction Preparation Aluminum honeycomb panels shall be fully fabricated in the factory.

The panel surface must be flat, uniform in color, and dimensionally accurate. All four edges shall have uniformly punched hanging notches, clean-cut edges, and undamaged corners. Prior to installation, panels shall be sorted and matched by model, specification, and color code. Reference: ASTM C1178-20 Standard Specification for Aluminum Honeycomb Core Panels; YS/T 429.2-2000 (Chinese industry standard for aluminum curtain wall panels)

2. Quality Requirements

1. Inspect all honeycomb panels before installation. Immediately report any damage, fabrication errors, or color variation to the Project Management Team. 2. Maintain a 20 mm expansion joint between aluminum honeycomb panels and the ceiling finished elevation; ensure uniform ceiling level across the entire area. 3. φ6 bolts shall be fully tightened with rubber washers installed over the shanks to prevent panel loosening and metal-to-metal contact. 4. Precise control of in/out alignment at panel hanging points is critical to avoid unevenness after installation. 5. Aluminum ceiling angle trims must be securely fixed. 6. Remove protective film only at joint gaps during installation; do not fully strip film until project completion. Implement proper finished product protection after full installation.

2.1 Guaranteed Quality Items (Critical Acceptance Criteria)

1. Variety, specifications, and color of facing panels must fully comply with design requirements; material quality shall conform to relevant national aluminum panel standards.
2. Number, position, and dimensions of openings/notches in framing and facing panels shall meet design specifications.
3. Facing panels must be securely installed with no skew, edge damage, or cracking. Quantity, specifications, position, connection method, and anti-corrosion treatment of all connectors shall comply with design requirements.

2.2 Basic Quality Items

1. Surfaces shall be straight, level, clean, and consistent in color.
2. Panel joints shall be dense and straight; joint width and depth shall conform to design requirements; sealing materials shall be uniform in color.
3. Openings on facing panels shall be neatly cut with clean edges.

2.3 Quality Acceptance Standards

3. Safety & Civilized Construction Requirements + Emergency Protocols

1. All personnel must wear safety helmets (ANSI Z89.1 / GB 2811-2019) on-site. Safety harnesses (GB 6095-2021) are mandatory for work at heights (>2m). No alcohol consumption before/during work; no slippers allowed on-site.
2. Strict no-smoking policy on construction site. Disconnect all power switches before departure to de-energize equipment; ensure no hazards exist before leaving.
3. When using A-frame ladders or mobile scaffolding, wear safety harnesses, install guardrails, and secure fall-arrest lines.

5.1 Surveying & Setting Out

5.2 Base Framing

• Fix 200×200×10 mm galvanized steel plates to the substrate using expansion bolts (compliant with GB/T 20049-2006).
• Secure vertical 50×50×5 mm galvanized square steel tubes (SHS) via steel adaptors.
