Fireproof Doors TRIZ Cases
- Gravity-Held Fire Cover for Drywall Openings
A closable fire protection opening uses a form-fit between the cover edge and panel opening to retain the cover by gravity alone.
- Fire Protection Revolving Door With Sliding Element
A fire protection door construction combines a sliding door and revolving door to create a continuous wide opening for large objects.
- Door Lock Access Control Mounting with Thermal Release
A temperature-responsive retainer releases a spring to disconnect wires, removing combustible materials before ignition.
- Flush Transom Elevator Door Frame Fire Barrier Design
Offsetting the fire-rated rear partition behind the transom eliminates the protruding head jamb while maintaining structural integrity and aesthetic continuity.
- Wooden Fire Door Frame with Intumescent Board and Tongue-Groove Joint
An intumescent board core in a wooden frame slows burning via evaporation cooling, while tongue-groove joints eliminate thermal bridges from screws.
- Secondary Seal with Cooling Property for Fire Protection Glazing
A secondary seal releases cooling gases to lower edge temperatures in fire protection glazing.
- Fire Door Fastening Assembly with Articulated Hinges
Articulated hinges connect the fire door frame to the bulkhead, allowing relative movement and reducing mechanical stress on the assembly.
- Fire Separation Door With Vertical Bar Locks For Flexible Access
Segmented fire separation doors use vertical bar locks engaging end rails to create larger passage areas without complex unhinging mechanisms.
- Fire Door Glass Panel with Low Emissivity Coating
Low emissivity layers on heat strengthened glass reflect flame heat, avoiding expensive fireproof sheets while meeting ISO 834 standards.
- Movable Gate Segments Fire Protection Textile Transition Sealing
Fire-resistant textile bridges movable gate segment transitions to seal gaps and prevent smoke spread without restricting mobility.
- Ligature Safe Door With Magnetic Release And Fire Sock
Frameless safe door employs magnets and fire sock to remove ligature risks while maintaining structural integrity.
- Double-Leaf Door Pressure-Equalizing Channel for Fire Safety
A double-leaf door uses a pressure-equalizing channel to balance air pressure across the leaf.
- Transparent Spacers for Fire-Resistant Glazing
Transparent spacers resolve the trade-off between illumination intensity and fire resistance in glazed walls.
- Building Closure Thermoplastic Reinforcement
A building closure integrates a rigid thermoplastic plate within the door leaf to enhance structural rigidity and impact resistance.
