Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to a fireproof aluminum alloy window. Background Art

[0002] Aluminum alloy windows are windows with frame and sash structures made of aluminum alloy profiles, which are divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows. This kind of window has the characteristics of beautiful appearance, sealing, high strength, and easy processing, so it is widely used in the field of construction engineering.

[0003] The glass panels installed on aluminum alloy windows are prone to softening and deformation after being heated at the fire scene. After the glass softens and deforms, gaps are easily generated, allowing flames and smoke to pass through, which will affect the fire resistance of the aluminum alloy windows. The purpose of the utility model is to improve the existing aluminum alloy window structure to improve its fire resistance, which will play a positive role in curbing the spread of fire. Utility Model Content

[0004] The utility model aims to provide a fireproof aluminum alloy window to solve the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a window frame, a window sash, a glass plate, a fire-proof expansion sealing strip, a movable frame and a mica tape, the window sash is installed on the window frame, the glass plates are arranged in pairs and installed on the front and rear sides of the window sash, the fire-proof expansion sealing strip is located in the space formed by the glass plate and the window sash, the movable frame is located above the fire-proof expansion sealing strip, the two sides of the movable frame respectively press against the glass plate and form a movable pair in the vertical direction with the glass plate, the mica tape is located on both sides of the movable frame, one end of the mica tape is connected to the bottom end of the window sash, and the other end of the mica tape is wound into a roll and placed on the top surface of the movable frame.

[0006] To optimize the above technical solution, further measures are taken: several gaps for the mica tape to pass through are set on both sides of the movable frame, and the gaps are set in the vertical direction. The setting of the gaps allows the mica tape to pass through the gap between the movable frame and the glass plate.

[0007] Preferably, the top of the movable frame is circumferentially integrated and protrudes upward to form a frame shape, and the frame structure helps to limit one end of the mica tape wound into a roll and reduce the displacement of the end of the mica tape.

[0008] In order to optimize the above technical solution, further measures are taken: a thermosetting adhesive is placed in the movable frame, and the thermosetting adhesive will solidify after being heated by the high temperature at the fire scene, so that the mica tape is bonded and fixed to the inner side of the glass plate.

[0009] As a further improvement of the above technical solution: the surface of the moving frame is covered with a low-melting-point film to seal the surface of the moving frame, and the end of the mica tape is wound into a roll and placed on the low-melting-point film. The purpose of setting the low-melting-point film is to separate the mica tape from the thermosetting adhesive. After the aluminum alloy window is heated, the low-melting-point film will melt rapidly to make the mica tape contact with the thermosetting adhesive.

[0010] Preferably, the unfolding direction of the mica tape is parallel to the vertical direction, and the length of the mica tape is greater than the height of the glass plate, ensuring that the mica tape can cover the glass plate in the vertical direction, supporting and connecting the glass plate and the expanded fire-resistant expansion sealing strip.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides a fireproof aluminum alloy window. By arranging a mica tape that can be expanded after being heated and cooperating with a thermosetting adhesive, a glass plate, the mica tape and an expanded fireproof expansion sealing strip can be bonded together, effectively blocking flames and delaying fire, and preventing the softening and failure of the glass plate from affecting the fireproof effect of the aluminum alloy window.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-2The utility model provides a fireproof aluminum alloy window, including a window frame 1, a window sash 2, a glass plate 3, a fireproof expansion sealing strip 4, a movable frame 5 and a mica tape 6. The window sash 2 is installed on the window frame 1, and the glass plates 3 are arranged in pairs and installed on the front and rear surfaces of the window sash 2. The fireproof expansion sealing strip 4 is located in the space formed by the glass plate 3 and the window sash 2. The movable frame 5 is located above the fireproof expansion sealing strip 4. The top of the movable frame 5 is circumferentially integrated and upwardly protrudes to form a frame shape. The two sides of the movable frame 5 respectively abut against the glass plate 3 and the glass plate 3 to form a movable pair in the vertical direction. The mica tape 6 is located on both sides of the moving frame 5, one end of the mica tape 6 is connected to the bottom end of the window sash 2, and the other end of the mica tape 6 is wound into a roll and placed on the top surface of the moving frame 5, the unfolding direction of the mica tape 6 is parallel to the vertical direction, the length of the mica tape 6 is greater than the height of the glass plate 3, and a plurality of gaps 501 for the mica tape 6 to pass through are provided on both sides of the moving frame 5, and the gaps 501 are arranged along the vertical direction. A thermosetting adhesive 502 is placed in the moving frame 5, and the surface of the moving frame 5 is covered with a low-melting-point film 503 to seal the surface of the moving frame 5, and the end of the mica tape 6 is wound into a roll and placed on the low-melting-point film 503.

[0020] The fire-proof expansion sealing strip 4 refers to a strip-shaped component in the prior art whose volume can expand rapidly after being heated. It is used for filling and has fire and smoke prevention effects. This component is widely used in this technical field and is known to those skilled in the art. Therefore, the specific structure and working principle of the fire-proof expansion sealing strip 4 will not be further explained.

[0021] The thermosetting adhesive 502 refers to an adhesive with thermosetting properties. The mica tape 6 adheres to the thermosetting adhesive 502 and contacts the glass plate 3. The thermosetting adhesive 502 is then cured by the high temperature at the fire scene, so that the mica tape 6 is bonded and fixed to the inner side of the glass plate 3. Technical personnel can use different types of thermosetting adhesives 502 according to actual needs. As long as the above requirements are met, they can be applied and will not have a substantial impact on the technical effect.

[0022] The mica belt 6 refers to a fire-resistant insulating material in the prior art, which has excellent high temperature resistance and combustion resistance. The purpose of the mica belt 6 is to support the expanded fireproof expansion sealing strip 4 and the glass plate 3.

[0023] The low-melting-point film 503 refers to a film-like component made of a low-melting-point plastic material. The low-melting-point property enables the low-melting-point film 503 to melt quickly after the aluminum alloy window is heated, thereby causing the mica tape 6 to contact the thermosetting adhesive 502. The specific material of the low-melting-point film 503 is not a necessary technical feature nor is it a technical content to be protected by the applicant. Therefore, no further explanation will be given. Technicians can choose different materials with different melting points according to actual needs.

[0024] Working principle: After a fire occurs, the temperature of the aluminum alloy window will gradually rise due to heat conduction. When the temperature reaches the melting point of the low-melting-point film 503, the low-melting-point film 503 melts, and at this time, one end of the rolled-up mica tape 6 will fall into the thermosetting adhesive. Subsequently, when the temperature of the aluminum alloy window rises to the expansion temperature of the fireproof expansion sealing strip 4, the fireproof expansion sealing strip 4 will expand due to the heat. The expanded fireproof expansion sealing strip 4 will fill the gap 501 of the glass plate 3 and drive the moving frame 5 to move upward. During the upward movement, the moving frame 5 will drive one end of the rolled-up mica tape 6 to unfold and adhere to the inner surface of the glass plate 3 along the gap 501. The expanded fireproof expansion sealing strip 4 can fill the gap 501 of the glass plate 3 to improve the fireproof function of the aluminum alloy window. At the same time, the thermosetting adhesive 502 attached to the surface of the mica tape 6 will gradually cure by heat, so that the mica tape 6 is adhered to the glass plate 3 and the expanded fireproof expansion sealing strip 4, so as to prevent the softening and deformation of the glass plate 3 from affecting the fireproof effect.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
