DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] Reference Figure 1-Figure 4As shown, a tempered hollow glass structure with good fire resistance performance includes a fixed frame 1, a first glass 2 and a second glass 16 are fixedly installed in the fixed frame 1, a closed space is formed between the first glass 2, the second glass 16 and the fixed frame 1, a radiation-proof layer is bonded to the surface of the first glass 2, and a fire-proof layer is bonded to the surface of the second glass 16. During installation, the first glass 2 is installed on the outside, and the radiation-proof layer can reduce the radiation of sunlight, and the second glass 16 is installed on the inside of the room. When the room is on fire, the fire-proof layer can play a fire-proof role in terms of movement to prevent The second glass 16 is burned, and multiple air outlet holes 3 are provided on both sides of the fixed frame 1. Multiple U-shaped brackets 4 are fixedly installed in the fixed frame 1, and the multiple brackets 4 are respectively located at the multiple air outlet holes 3. A movable hole is provided on the bracket 4, and a movable rod 5 is slidably installed in the movable hole. A sealing plug 6 is fixedly installed at one end of the movable rod 5, and one end of the sealing plug 6 is inserted in the air outlet hole 3. A round block 7 is fixedly installed at the end of the movable rod 5 away from the sealing plug 6. A memory spring 8 is sleeved on the movable rod 5, and the two ends of the memory spring 8 are fixedly connected with the round block 7 and the bracket 4 respectively.

[0017] The memory spring 8 is a spring made of memory metal, which is a prior art. At room temperature, the memory spring 8 will not be strained. At this time, the sealing plug 6 is inserted in the air outlet 3, thereby blocking the air outlet 3 to prevent impurities in the air from entering the insulating glass through the air outlet 3. When a fire occurs, the pressure inside the insulating glass will increase, and the temperature inside the insulating glass will also increase sharply. When the high temperature reaches a critical value, the memory spring 8 will be rapidly compressed. At this time, the memory spring 8 will drive the sealing plug 6 to move out of the air outlet 3 and automatically open the air outlet 3. The air pressure on the inner wall of the insulating glass will be rapidly reduced through the opening of the air outlet 3 to avoid excessive air pressure, thereby preventing the insulating glass from breaking, and effectively improving the safety of the insulating glass.

[0018] A sound insulation board 9 is installed on the first glass 2 through multiple groups of elastic components. The sound insulation board 9 is slidably set in the fixed frame 1. A plurality of mounting holes are opened on the surface of the sound insulation board 9. Sound-absorbing cotton 13 is fixedly installed in the plurality of mounting holes. The sound insulation board 9 is installed between the first glass 2 and the second glass 16. The sound insulation board 9 can play a certain role in isolating sound. At the same time, the sound-absorbing cotton 13 can absorb noise, thereby further playing a role in isolating noise.

[0019] A plurality of cross bars 14 are fixedly installed in the fixed frame 1, and a protective net 15 is fixedly installed on the plurality of cross bars 14. The protective net 15 is located between the second glass 16 and the sound insulation board 9. The fireproof layer can only play a role of high temperature resistance to a certain extent. When the fire is large, the second glass 16 may be broken. When the second glass 16 is broken, the splashing glass will hit the protective net 15, which plays a buffering role for the splashing glass and prevents the splashing glass from hitting the sound insulation board 9 and the first glass 2. The first glass 2 and the sound insulation board 9 are protected, the degree of breakage of the insulating glass is reduced, and the difficulty of later maintenance is reduced.

[0020] A plurality of connection holes are provided on the sound insulation board 9, and the elastic component includes a support rod 10 slidably installed in the connection hole, a block 11 fixedly installed at one end of the support rod 10, and a buffer spring 12 sleeved on the support rod 10. One end of the support rod 10 is fixedly connected to the first glass 2, and the two ends of the buffer spring 12 are respectively fixedly connected to the first glass 2 and the sound insulation board 9. The sound insulation board 9 is installed on the first glass 2 through the support rod 10 and the buffer spring 12. Under the action of the elastic force of the buffer spring 12, the sound insulation board 9 can be buffered and shock-absorbed, which can further improve the sound insulation effect of the sound insulation board 9. At the same time, when the protective net 15 is broken, it can also play a buffering role for the splashing glass, further improving the safety of the hollow glass.

[0021] When a fire occurs, the pressure inside the insulating glass will increase, and the temperature inside the insulating glass will also increase sharply. When the high temperature reaches a critical value, the memory spring 8 will be rapidly compressed. At this time, the memory spring 8 will drive the sealing plug 6 to move out of the air outlet 3 and automatically open the air outlet 3. The air pressure on the inner wall of the insulating glass will be rapidly reduced by opening the air outlet 3 to avoid excessive air pressure, thereby preventing the insulating glass from breaking and effectively improving the safety of the insulating glass.
