Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figure 1-6 This utility model provides an embodiment of a flame-retardant glass curtain wall, comprising a glass curtain wall body 1. The glass curtain wall body 1 includes a first flame-retardant structural surface layer 2, a fireproof core structure 3, a second flame-retardant structural surface layer 4, and a composite flame-retardant film 5. The first flame-retardant structural surface layer 2 is installed on one side surface of the fireproof core structure 3, and the second flame-retardant structural surface layer 4 is installed on the other side surface of the fireproof core structure 3. The composite flame-retardant film 5 covers the outer surfaces of the first flame-retardant structural surface layer 2 and the second flame-retardant structural surface layer 4. Limiting frames 25 are installed at both ends of the glass curtain wall body 1, and fire sensors 23 are detachably installed on the limiting frames 25. Horizontal beams 15 are installed at both the upper and lower ends of the glass curtain wall body 1, and multiple water spray nozzles 16 are provided on the front end surface of the horizontal beams 15.
[0027] Furthermore, the composite flame-retardant film 5 includes a flame-retardant PE film 6, a flame-retardant PP film 7, and a flame-retardant PVC film 8. The flame-retardant PE film 6 is wrapped around one side of the flame-retardant PP film 7, and the flame-retardant PVC film 8 is wrapped around the other side of the flame-retardant PP film 7. By setting up a multi-layer flame-retardant and environmentally friendly film structure and a multi-layer fireproof and flame-retardant structure, the composite flame-retardant film can effectively resist external fire erosion and has good high-temperature fireproof effect.
[0028] Furthermore, the first flame-retardant structural surface layer 2 and the second flame-retardant structural surface layer 4 include a fireproof ceramic fiber board 9, a flame-retardant adhesive board 10, and a fireproof rock wool board 11. The fireproof ceramic fiber board 9 is tightly bonded and fixed to the fireproof rock wool board 11 through the flame-retardant adhesive board 10. The fireproof ceramic fiber board 9, the flame-retardant adhesive board 10, and the fireproof rock wool board 11 are made of high-temperature resistant and flame-retardant materials such as ceramic fiber and rock wool, which can reduce the heat transfer from the glass to the metal frame and prevent the glass from cracking due to thermal stress.
[0029] Furthermore, the fire-resistant core structure 3 includes a single-layer cesium potassium fire-resistant glass 12, a fire-resistant laminated glass 13, and a fire-resistant film glass 14. The single-layer cesium potassium fire-resistant glass 12 is disposed on one side of the fire-resistant laminated glass 13, and the fire-resistant film glass 14 is disposed on the other side of the fire-resistant laminated glass 13. By using the single-layer cesium potassium fire-resistant glass 12 as the material of the fire-resistant core structure 3 of the curtain wall, the single-layer cesium potassium fire-resistant glass 12 is formed by special chemical treatment on the surface of ordinary glass to form a cesium potassium ion exchange layer with good fire resistance. The fire-resistant laminated glass 13 has good light transmittance and can maintain its integrity and heat insulation for a certain period of time during a fire, preventing the spread of fire. The fire-resistant film glass 14 is composed of two or more layers of glass with a fire-resistant film sandwiched in between. The fire-resistant film expands when heated, forming a heat-insulating and smoke-proof barrier to prevent the transfer of heat and flames.
[0030] Furthermore, a mounting plate 24 is provided on the side surface of the fire sensor 23. The surface of the mounting plate 24 is fixedly connected to the surface of the limiting frame 25 by fixing bolts 22, which has the advantage of convenient installation and fixing.
[0031] Furthermore, a sealing ring 17 is provided on the side surface of the crossbeam plate 15. The water spray nozzle 16 is connected to the sealing ring 17 through a pipeline. One end of the sealing ring 17 is sealed to the water pump 20 through the water inlet pipe 18. An electrically controlled switch valve 19 is installed on the water inlet pipe 18. One end of the water pump 20 is connected to the tap water network through the water pumping pipeline 21. A fire sensor 23 is detachably installed on the limiting frame 25. The fire sensor 23 can be used to monitor the surrounding fire situation in real time. When a fire occurs, the fire sensor 23 can be used to feed back relevant signals to the electrically controlled switch valve 19, causing the water pump 20 to quickly spray water from inside the tap water network through the water spray nozzle 16 for fire extinguishing operations. It has a high degree of automation and functions as a fire monitor and active fire extinguisher.
[0032] Working principle: In use, the glass curtain wall main body 1 includes a first flame-retardant structural surface layer 2, a fireproof core structure 3, a second flame-retardant structural surface layer 4, and a composite flame-retardant membrane 5. The first flame-retardant structural surface layer 2 is installed on one side of the fireproof core structure 3, and the second flame-retardant structural surface layer 4 is installed on the other side of the fireproof core structure 3. The composite flame-retardant membrane 5 covers the outer surfaces of the first flame-retardant structural surface layer 2 and the second flame-retardant structural surface layer 4. By setting multiple layers of flame-retardant and environmentally friendly membrane structure and multiple layers of fireproof and flame-retardant composite flame-retardant membrane structure, it can effectively resist external fire erosion and has good high-temperature resistance and fireproof effect. The fireproof ceramic fiber board 9, the flame-retardant adhesive board 10, and the fireproof rock wool board 11 are made of ceramic fiber, rock wool, and other high-temperature resistant materials. Made of heat-resistant and flame-retardant materials, it can reduce heat transfer from the glass to the metal frame and prevent the glass from cracking due to thermal stress. By using monolithic cesium potassium fire-resistant glass 12 as the fire-resistant core structure 3 material of the curtain wall, the monolithic cesium potassium fire-resistant glass 12 is made by special chemical treatment on the surface of ordinary glass to form a cesium potassium ion exchange layer with good fire resistance. The fire-resistant laminated glass 13 has good light transmittance and can maintain its integrity and heat insulation for a certain period of time in the event of a fire, preventing the spread of fire. The fire-resistant film glass 14 is composed of two or more layers of glass with a fire-resistant film sandwiched in between. The fire-resistant film expands when heated, forming a heat-insulating and smoke-proof barrier to prevent the transfer of heat and flames.
[0033] Limiting frames 25 are installed at both ends of the glass curtain wall body 1. Fire sensors 23 are detachably installed on the limiting frames 25. Horizontal beams 15 are installed at both the upper and lower ends of the glass curtain wall body 1. Multiple water spray nozzles 16 are provided on the front surface of the horizontal beams 15. By detachably installing fire sensors 23 on the limiting frames 25, the fire sensors 23 can be used to monitor the surrounding fire situation in real time. When a fire occurs, the fire sensors 23 can be used to feed back relevant signals to the electronically controlled switch valve 19, causing the water pump 20 to quickly spray water from the tap water network through the water spray nozzles 16 for fire extinguishing operations. It has a high degree of automation and functions as a fire monitor and active fire extinguisher.
