Description

Technical Field

[0001] The present application relates to the field of fireproof windows, and in particular to a fireproof glass window. Background Art

[0002] Current buildings have more requirements for fire protection. As a fire protection measure, fireproof windows are increasingly used in the current construction field. Fireproof windows need to be closed in a fire and play a role in isolating the spread of flames for a certain period of time. Therefore, thermal insulation and flame retardancy are very important performance indicators of fireproof windows.

[0003] In the relevant technology, there are many types of fireproof windows. Most of them have various optimizations in materials and structures. For example, special explosion-proof glass or double-layer glass are used to enhance the thermal insulation and flame retardancy of fireproof windows. Some also perform "vacuum" treatment between the double-layer glass or add additional panels for further strengthening.

[0004] Regarding the above-mentioned related technologies, the so-called "vacuum" interlayer of the currently common double-glazed windows cannot achieve a true vacuum. Most of them are actually a slightly negative pressure environment, and adding other materials will affect the transparency of the glass. Therefore, the current double-glazed fireproof windows still lack thermal insulation and flame retardant effects. Utility Model Content

[0005] In order to enhance the heat insulation and flame retardancy effects, the present application provides a fireproof glass window.

[0006] The present application provides a fireproof glass window, which adopts the following technical solution:

[0008] By adopting the above technical solution, the negative pressure cavity between the double-layer glass is easier to achieve than vacuum, and there is no excess material that hinders the transparency of the double-layer glass; when a fire occurs, the opening device is activated to tear the airbag, and the aerogel powder quickly fills the negative pressure cavity under pressure, thereby utilizing the aerogel powder to enhance the heat insulation and flame retardant effect of the double-layer glass.

[0010] By adopting the above technical solution, when the induction sensor senses a fire, it controls the spark generator through a signal to generate a spark. The spark contacts the airbag and then cooperates with the air pressure to tear the airbag and discharge the aerogel powder. The structure is simple and the response speed is fast.

[0011] Optionally, the induction sensor is a temperature sensor and / or a smoke sensor, and an end of the induction sensor extends outside the chamber.

[0012] By adopting the above technical solution, both the temperature sensor and the smoke sensor can effectively sense the occurrence of fire and ensure that the fireproof window is accurately triggered.

[0013] Optionally, the installation frame is provided with a replacement hole for the airbag to pass through, the replacement hole is communicated with the chamber, the installation frame is detachably connected with a baffle for closing the replacement hole, and a seal is provided between the baffle and the installation frame.

[0014] By adopting the above technical solution, the setting of the replacement hole can make the airbag replaceable, so that the fireproof window can be used continuously, and the replacement cost can be reduced in cases such as the fireproof window being triggered by mistake.

[0015] Optionally, the baffle and the mounting frame are connected by bolts.

[0016] By adopting the above technical solution, the bolt fixing method has a simple structure and is stable and reliable, ensuring the normal function of the baffle.

[0018] By adopting the above technical solution, the rubber strip, the convex ring and the groove can achieve a stable sealing effect, and combined with the fixing method of the baffle bolts, the installation process is simpler and more efficient.

[0019] Optionally, the mounting frame is connected to an air nozzle, which is connected to the negative pressure chamber.

[0020] By adopting the above technical solution, the user can use the air nozzle to periodically pump negative pressure into the negative pressure chamber to ensure a negative pressure environment in the negative pressure chamber, thereby ensuring that the fireproof window is effective for a long time.

[0021] Optionally, a fireproof self-closing device is connected between the window sash and the window frame.

[0022] By adopting the above technical solution, the fireproof self-closing device can quickly close the fireproof window when a fire occurs, ensuring the smooth realization of the fireproof window function.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses a fireproof glass window.

[0033] Reference Figure 1 and Figure 2 A fireproof glass window comprises a window frame 1 and a window sash 2, the window sash 2 comprises a mounting frame 21 and double-layer glass 22, the edges of the double-layer glass 22 are sealed with the mounting frame 21 by sealant, a negative pressure cavity 221 is arranged between the double-layer glass 22, the negative pressure cavity 221 between the double-layer glass 22 is easier to achieve than vacuum, and there is no redundant material that hinders the transparency of the double-layer glass 22, so that fire prevention is achieved without affecting the transparency of the window itself.

[0034] Reference Figure 2 and Figure 3A chamber 211 is provided at the upper end of the mounting frame 21, and the chamber 211 is located at the edge of the double-layer glass 22. The chamber 211 is connected to the negative pressure chamber 221. An airbag 215 is provided in the chamber 211, and the interior of the airbag 215 is filled with aerogel powder. An opening device 4 for tearing the airbag 215 is also installed in the chamber 211. Specifically, the opening device 4 includes an electric spark generator 42 and an inductive sensor 41, and the electric spark generator 42 and the inductive sensor 41 are electrically connected through a circuit. The contact of the electric spark generator 42 abuts against the side of the airbag 215 close to the negative pressure chamber 221, and then when the electric spark generator 42 ignites, the airbag 215 is quickly torn by the dual effects of sparks and air pressure.

[0035] Reference Figure 2 and Figure 3 The induction sensor 41 may be a temperature sensor, a smoke sensor, or both. In this embodiment, it is preferred to use both the temperature sensor and the smoke sensor. At this time, the two sensors work together to improve the sensitivity of fire induction. The induction end of the induction sensor 41 extends to the outside of the chamber 211 to facilitate the occurrence of fire induction. In addition, a similar structure such as a heating wire may be used to achieve the tearing effect of the airbag 215 after power is turned on. This embodiment will not be elaborated in detail.

[0036] Reference Figure 2 and Figure 3 When a fire occurs, the temperature sensor and the smoke sensor can sense the occurrence of the fire in time and transmit an electrical signal to start the spark generator 42. The contact of the spark generator 42 generates sparks and tears the airbag 215, so that the aerogel powder in the airbag 215 can quickly enter the negative pressure chamber 221 under the action of air pressure, and fill the entire negative pressure chamber 221 due to the action of air pressure. The aerogel powder is used to achieve the purpose of heat insulation and flame retardancy, so as to enhance the fireproof effect of the fireproof glass window.

[0037] Reference Figure 2 and Figure 3 In order to enable the fireproof window to be used repeatedly, a replacement hole 212 is provided at the top of the mounting frame 21, and the replacement hole 212 is connected to the inside of the chamber 211, so as to facilitate the replacement of the airbag 215. A baffle 213 for closing the replacement hole 212 is also detachably installed at the top of the mounting frame 21, and a sealing member 214 is also provided between the baffle 213 and the mounting frame 21 to ensure the normal function of the fireproof window under normal conditions.

[0038] Reference Figure 2 and Figure 3The baffle plate 213 is fixed to the mounting frame 21 by a plurality of bolts, and the seal 214 therebetween ensures the sealing of the replacement hole 212. The seal 214 is specifically a rubber strip, which covers the circumferential side edge of the baffle plate 213. A convex ring 2131 is integrally formed on the side of the baffle plate 213 facing the mounting frame 21. The mounting frame 21 is provided with a groove matched with the convex ring 2131. When the baffle plate 213 is installed on the side of the mounting frame 21 by the bolts, the rubber strip is pressed into the groove by the convex ring 2131 to achieve a stable sealing effect.

[0039] Reference Figure 2 and Figure 3 When the airbag 215 needs to be replaced, it is only necessary to loosen the bolts and remove the baffle 213, and then the airbag 215 inside the chamber 211 can be replaced. After the replacement is completed, the replacement hole 212 is re-closed using the baffle 213, and the rubber strip, the convex ring 2131 and the groove are used to achieve sealing. The replacement process is simple and convenient, and there is no need to disassemble the installation frame 21 as a whole, so it is more flexible to use.

[0040] Reference Figure 2 and Figure 3 In this embodiment, the side of the mounting frame 21 is also connected with an air nozzle 5, and the air nozzle 5 is connected with the negative pressure chamber 221. The user can use the air nozzle 5 to regularly pump negative pressure into the negative pressure chamber 221 to ensure a stable negative pressure environment inside the negative pressure chamber 221, and ensure that the fireproof glass window can be effectively used for a long time.

[0041] Reference Figure 1 and Figure 3 In addition, a fireproof self-closing device 6 can be installed between the window sash 2 and the window frame 1. When a fire occurs, the fireproof self-closing device 6 can control the window sash 2 to close automatically, thereby further improving the fireproof effect of the fireproof glass window. The fireproof self-closing device 6 can also be electrically connected to the induction sensor 41 to achieve the automatic window closing effect. The sensor signal control of the fireproof self-closing device 6 is a relatively mature existing technology, and this embodiment will not be elaborated in detail.

[0042] The working principle of a fireproof glass window in an embodiment of the present application is as follows: by providing a window sash 2 composed of double-layer glass 22 and a negative pressure cavity 221, while ensuring good light transmittance, the negative pressure cavity 221 and aerogel powder can be used to enhance the heat insulation and flame retardancy of the window sash 2; by using an opening device 4, aerogel powder can be promptly filled into the negative pressure cavity 221 when a fire occurs, thereby achieving the purpose of heat insulation and flame retardancy.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
