Guangdun Door Industry Co., Ltd. Jindi Fire Door Project Overview
construction site
- Fire Door Project Overview
- Building Area: 11,771 m², with one basement and two floors above ground.
- Structural Form: Frame-shear wall structure with a first-class fire resistance rating.
- Fire-Resistant Steel Doors: The door frame, panel, and reinforcement components are made from electro-galvanized steel. Single-leaf doors are equipped with door closers, while double-leaf doors have cover plates and door closers. The fire resistance limits are as follows:
- Grade A Steel Fire Doors: Fire resistance of no less than 1.2 hours.
- Grade B Steel Fire Doors: Fire resistance of no less than 0.9 hours.
- Grade C Steel Fire Doors: Fire resistance of no less than 0.6 hours.
- Regulatory Basis The project follows several key regulations and standards:
- General Technical Conditions for Steel Fire Doors (GB12955-1991).
- Building Fire Protection Design Code (GBJ16-87).
- Unified Construction Quality Acceptance Standards (GB50300-2001).
- Building Decoration and Renovation Quality Standards (ZJQ00-SG-021-2006).
- Building Energy Efficiency Quality Standards (GB50411-2007).
- Indoor Air Quality Control for Civil Buildings (GB50325-2001).
- Construction Preparations 3.1 Technical Preparation
- Thoroughly understand the installation locations and site conditions.
- Fire Door Installation Locations & Fire Resistance Levels:
- Grade A Fire Doors: Fire compartment doors, electrical equipment room doors with a 1.2-hour fire resistance.
- Grade B Fire Doors: Staircase and lobby doors with a 0.9-hour fire resistance.
- Grade C Fire Doors: Pipe room access doors with a 0.6-hour fire resistance.
- All materials must be accompanied by certificates of quality, inspection reports, and eco-labels. Materials should be protected from sunlight, rain, and moisture, especially for wooden fire doors.
- Fire Door Transport: Ensure doors are securely packed to prevent surface scratches and ensure safe handling.
- On-Site Storage: Store fire doors on wooden pallets to prevent contact with the ground and protect them from moisture and impact.
- A variety of tools, such as wood wedges, impact drills, expansion bolts, measuring tapes, and welding tools, are necessary for accurate installation and adjustments during the fire door installation process.
- Installation Process
- Process Flow: Marking, door frame installation, temporary fixation, door leaf installation, and hardware fittings.
- Steel Fire Door Installation:
- Marking and Positioning: Mark door frame locations based on design specifications.
- Frame Installation: Ensure the door frame is square, vertical, and positioned correctly with gaps between the frame and wall sealed with cement mortar.
- Door Frame Fixing: Secure the frame with galvanized connectors and expansion bolts.
- Leaf Installation: Attach the door leaf to the frame using proper hinges and adjustments to ensure ease of operation.
- Hardware Fitting: Install locks, handles, and additional fire-resistant features.
- Quality Standards
- Key Quality Control Points:
- The fire doors should meet all the design specifications for material quality, fire resistance rating, and functionality.
- Installation: The door must be firmly installed, and its operation should be smooth with proper sealing upon closing.
- Mechanical Devices: Fire doors with automatic or smart features must meet the required standards for performance and reliability.
- Dimension Tolerances: Fire doors must adhere to strict dimensional tolerances:
- Door Height: ±2 mm
- Door Width: ±3 mm
- Door Thickness: ±2 mm
- Frame Slot Dimensions: ±3 mm
- Frame Side Width: ±2 mm
- Key Quality Control Points:
- Protection Measures
- Ensure fire doors are stored and installed without any risk of surface damage. Protective films should be used to avoid scratches during installation and handling.Fire Door Project Overview.
- After installation, the door should be carefully protected from external damage, such as during finishing work like plastering or painting.
- Safety and Civilized Construction Measures
- Installers must wear safety helmets and follow all safety regulations when using electrical tools and equipment.
- Regular checks should be performed on electrical tools to prevent hazards, ensuring a safe working environment.
- The use of ladders should be secure, and tools should be neatly stored to prevent accidents.
