All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. The preferred embodiments of this utility model will now be described in more detail with reference to the accompanying drawings. Although the preferred embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this utility model more thorough and complete, and to fully convey the scope of this utility model to those skilled in the art.

[0039] Please refer to Figures 1-7An integrated emergency escape fireproof safe house includes a main body 1 and a wall 101 connected to the inner side of the main body 1. The structural load-bearing capacity of the main body 1 meets the collapse resistance requirements of GB 50011—2010 Code for Seismic Design of Buildings and GB 50413—2007 Standard for Urban Seismic Disaster Prevention Planning. The fire resistance of the wall 101 meets the standard of GB50016—2014 Code for Fire Protection Design of Buildings. A fire door 102 is installed on one side of the wall 101, and the fire door 102 conforms to the standard GB... According to "Fire Doors 12955-2024", the bottom surface of the fire door 102 is provided with a sealing groove 1021. A fireproof sealing expansion strip 1022 and a touch-sensitive heating element 1023 are respectively connected to the inner side of the sealing groove 1021. Fireproof curtains 104 are installed on both opposite inner sides of the wall 101. A frame 1041 is installed on the outer side of the fireproof curtains 104. A magnetic track 1042 is connected to the top of the frame 1041, and rotating quick-release buckles 1043 are connected to the bottom and sides of the frame 1041. Specifically, the frame 1041 is made of alloy profiles, and a magnetic track is embedded at its top. Track 1042 uses a combination of permanent magnet and electromagnetic lock. The bottom and sides of frame 1041 are equipped with rotating quick-release buckles 1043, which are similar to the principle of camera lens buckles. They can be disassembled with one hand. In an emergency, the buckles can be manually rotated to unlock. In the event of a fire, the thermal sensor can also de-energize and release the electromagnetic lock. The magnetic track 1042 and rotating quick-release buckle 1043 system provide double protection. In the event of a fire, the fireproof curtain 104 can be quickly removed as an emergency fireproof item to ensure the safety of personnel. The overall fabric will not melt and drip in high-temperature environments, causing burns or other secondary injuries.

[0040] In addition, the walls 101 are made of fireproof and heat-insulating materials, and the interior is made of flame-retardant curtains, flame-retardant bedding (including but not limited to aramid, flame-retardant nylon, flame-retardant polyester, etc.) and fire-retardant latex paint. The whole structure meets the fire protection requirements of GB 55037-2022 General Code for Fire Protection of Buildings and GB 50016-2014 Code for Fire Protection Design of Buildings. The floor is covered with flame-retardant and smoke-resistant carpet. A communication mechanism 2 and a material storage 6 are installed on one opposite inner surface of the walls 101, and a power supply mechanism 3 and a fire protection equipment mechanism 4 are installed on the other opposite inner surface of the walls 101. An escape equipment mechanism 5 is also installed on the outside of the main body 1 of the safe house.

[0041] A groove is provided in the ground directly below the fire door 102 after it is closed. A fireproof sealing strip and a heating plate that match the specifications and materials of the fireproof sealing expansion strip 1022 and the touch heating plate 1023 at the bottom of the fire door 102 are embedded in the groove. Specifically, a sealing groove 1021 is opened at the bottom edge of the fire door 102, in which the fireproof sealing expansion strip 1022 and the touch heating plate 1023 are embedded. In the ground directly below the fire door 102 after it is closed, a groove is pre-dug, in which a fireproof sealing strip and a heating plate that match the specifications and materials of the sealing strip at the bottom of the door leaf are embedded. The upper and lower heating plates can be started with a one-button touch. After the heating temperature triggers the sealing expansion strip to expand, the power can be automatically cut off. Through the double sealing of the door leaf and the ground, the gaps caused by uneven ground, insufficient expansion of a single sealing strip, or installation deviation are fundamentally eliminated, and the smoke prevention reliability is extremely high. The fireproof door uses 102 halogen-free flame retardant, which avoids the release of toxic gases, making it environmentally friendly and safe. At the same time, the design does not passively rely on a tight fit with the ground, but actively fills the space through the opposing expansion of two active seals, which has a higher tolerance for ground flatness and door deformation. The structure is simple and easy to implement.

[0042] Furthermore, this solution simply adds a pre-embedded sealing strip to the existing fire door 102 technology, eliminating the need for complex transmission mechanisms or external power. This results in low modification costs and ease of adoption in both new construction and renovation projects. Maintenance is convenient; if the embedded sealing strip ages or is damaged, it can be replaced. Maintenance is simple and direct, requiring no changes to the main door structure.

[0043] The fireproof panel of fire door 102 is coated with a nano-coating that is resistant to high temperatures and reflects heat radiation. Specifically, this coating includes ceramic-based coatings (zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc.); metal-ceramic composite coatings (metal-ceramic functionally graded materials (FGM), nanoporous ceramic coatings, etc.); metal reflective layers (aluminum (Al) or silver (Ag) coatings, metal-ceramic protective layer combinations (such as aluminum coating + silicon oxide protective layer), stainless steel plating, etc.); nanomaterials (nano titanium oxide (TiO2), zinc oxide (ZnO) coatings, graphene / carbon nanotube composites, etc.); and aerogel composites (silica aerogel, etc.).

[0044] The intermediate layer adopts a honeycomb structure and is filled with a composite layer of phase change energy storage material and nano-aerogel. While reducing weight, the phase change material absorbs heat and slows down the temperature rise, and the aerogel provides an ultra-low thermal conductivity. Specifically, the intermediate layer structure includes honeycomb structure, corrugated layer structure, foam sandwich structure, lattice structure, laminated composite structure, etc. The intermediate layer materials include aerogel composite materials, phase change composite materials, and foam composite materials, such as rock wool board, aluminum silicate fiber material, expanded perlite, expanded vermiculite, diatomaceous earth, calcium silicate board, phenolic foam, etc.

[0045] The inner layer is an integrated intumescent fireproof coating containing self-developed high-performance thermally expanding microspheres. The microspheres expand when exposed to high temperatures (expansion rate ≥3000%). The addition ratio of thermally expanding microspheres can be set to 5% to 20%. When heated, the microspheres not only absorb heat to help cool down, but also increase the thickness of the fire door 102 after expansion, forming a heat-insulating air layer and improving the heat insulation of the fire door 102. Specifically, the inner layer includes fire-resistant fiberboard such as aluminum silicate fiber, rock wool / mineral wool board, calcium silicate board, gypsum-based fireproof board, expanded perlite / vermiculite board, glass fiber reinforced cement board (GRC), ceramic fiber board, or steel frame treated with intumescent fireproof coating.

[0046] The fireproof curtain 104 is composed of fireproof composite materials. The outer layer is a flame-retardant fabric of aramid fiber or other high-performance fiber (such as flame-retardant wool, flame-retardant cotton and linen, aramid (Nomex), metal-coated fabric, fiberglass cloth, aluminum silicate fiber, ceramic fiber, basalt fiber, etc.), the middle layer is a nano aerogel heat insulation layer (such as graphene aerogel, aramid aerogel, etc.), and the inner layer is a phase change energy storage material (such as paraffin / hydrated salt composite, etc.), which can absorb heat energy and maintain a stable surface temperature. The rotating quick-release buckle 1043 is also connected to an intelligent trigger module 1044 on one side. The intelligent trigger module 1044 integrates a thermal sensor. The trigger temperature range of the thermal sensor is 60℃-80℃. When the temperature is high, the electromagnetic lock is automatically released and an alarm signal pops out.

[0047] Communication mechanism 2 includes a locator 201 and an alarm 202, which are electrically connected. Communication mechanism 2 also includes a hand-cranked emergency radio 203. Communication mechanism 2 integrates a positioning terminal and a high-frequency whistle, and is equipped with a hand-cranked emergency radio 203, supporting dual distress signals of sound and light. The positioning module of locator 201 uses a portable positioning terminal with short cold and hot start times, supports multi-system compatible positioning, and automatically sends positioning information to a preset rescue platform. Communication mechanism 2 is equipped with an emergency radio that supports AM / FM bands and has a hand-cranked power generation function, which can charge the mobile phone at the same time.

[0048] The power supply mechanism 3 includes an emergency power supply 301 and an energy storage power supply 302. The emergency power supply 301 and the energy storage power supply 302 are electrically connected. A lighting strip 105 is connected to the inner top surface of the wall 101. The power supply mechanism 3 is electrically connected to the communication mechanism 2 and the lighting strip 105 respectively. The power supply mechanism 3 prioritizes the power supply of communication equipment and lighting, supports the simultaneous charging of multiple devices, meets the requirements of the "GB50052-2009 Power Supply and Distribution System Design Code", and can be equipped with a solar energy system, install monocrystalline silicon solar panels, and be equipped with an MPPT controller and lithium batteries. It can maintain the charging capacity on sunny days and prioritizes the power supply of positioning terminals and satellite phones.

[0049] Fire protection equipment component 4 includes a water-based fire extinguisher 401 and a breathing mask 402, as well as a flame-retardant hood and fire blanket. The water-based fire extinguisher 401 conforms to the standards "GB 50140—2005 Code for Design of Fire Extinguisher Configuration in Buildings" and "GB4351.1-2005 Handheld Fire Extinguishers Part 1: Performance and Structural Requirements," and is suitable for Class A / B / C fires. When used with high-pressure fine water mist devices, it can extinguish initial fires. The breathing mask 402 is a filtering fire-fighting self-rescue breathing apparatus with a protection time of ≥30 minutes. The fire blanket is made of special fabric and has characteristics such as high temperature resistance, flame retardancy, and reusability. It can not only prevent the spread of small fires in the early stages of a fire, but also be worn during escape to prevent burns and ensure escape safety.

[0050] The escape equipment mechanism 5 is specifically a descent device 501. The descent device 501 has flame-retardant and high-temperature resistant properties, including a flame-retardant escape rope, a window breaker, and flame-retardant, high-temperature resistant, and non-slip gloves, supporting the rapid evacuation of multiple people.
