Description

A fireproof and noise-reducing skylight Technical Field

[0001] This utility model relates to the field of fireproof window technology, specifically a fireproof and noise-reducing skylight. Background Technology

[0002] Windows are an important component of architectural design, playing a crucial role in the contrast between solid and void and in creating rhythmic artistic effects. Therefore, their shape, size, proportion, arrangement, color, and form all significantly influence the overall architectural design. Skylights, in particular, offer high efficiency in both lighting and ventilation. Modern architecture employs a wide variety of skylight applications, which can be broadly categorized into three types based on their structure, location, and relationship to the roof: zenith-type, protruding type, and recessed type.

[0003] Most existing skylights are top-hung type with a limited opening angle, meaning they can only be opened to a maximum angle and then cannot be opened further. Due to the uncertainty of wind direction, headwinds can obstruct the normal flow of air into the room, reducing ventilation. However, because skylights open top-hung, even in headwinds, some air can still enter the room along the bottom of the window sash, although the ventilation efficiency is not as high as when the wind is with the current. At the same time, headwinds may cause turbulence in the indoor air, affecting the even distribution of indoor air. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a fireproof and noise-reducing skylight. It solves the problem that most existing skylights are top-hung type with limited opening angles, only able to open to a maximum angle before stopping. Furthermore, due to the uncertainty of wind direction, headwinds can obstruct normal airflow into the room, reducing ventilation. However, because the skylight is top-hung, even in headwinds, some air can still enter the room along the bottom of the window sash, although the ventilation efficiency is not as high as in a downwind situation. Additionally, headwinds can cause turbulence in the indoor air, affecting the uniform distribution of indoor air.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fireproof and noise-reducing skylight, including a skylight frame, a limiting groove is provided at the bottom of the skylight frame, and a first connecting shaft is connected inside the skylight frame;

[0006] A first connecting shaft, a first connecting plate connected to one side of the first connecting shaft, a second connecting shaft connected to the other end of the first connecting plate, a second connecting plate connected to the other end of the second connecting shaft, and another first connecting shaft installed on the other end of the second connecting plate and connected to the inner wall of the limiting frame;

[0007] The skylight frame has a double-layered laminated fireproof glass installed on its top, and the double-layered laminated fireproof glass has an ion exchange glass installed inside.

[0008] Preferably, the limiting frame is located directly below the limiting groove, and the limiting frame is fitted inside the limiting groove, and a thermoplastic elastomer sealing strip is provided on the outside of the limiting frame.

[0009] Preferably, a sunroof base plate is installed at the bottom of the limiting frame, and a light-blocking opening is provided at the bottom of the sunroof base plate, with a groove provided on one side of the light-blocking opening.

[0010] Preferably, a telescopic sunshade is provided inside the groove, and a handle is connected to the bottom of one side of the telescopic sunshade.

[0011] Preferably, a sound-absorbing panel is connected to the bottom of the skylight base plate, and a fireproof rock wool board is connected to the bottom of the sound-absorbing panel.

[0012] Preferably, a window breaker bracket is installed at the bottom of the fireproof rock wool board, and a window breaker is installed inside the window breaker bracket.

[0013] This invention provides a fireproof and noise-reducing skylight. Compared with the prior art, it has the following advantages:

[0014] A fireproof and noise-reducing skylight opens by lifting the skylight frame. Since the skylight frame and the limiting frame are connected by a first connecting rod and a second connecting rod through a second connecting shaft, the skylight frame can rotate with the rotation of the first connecting shaft, causing the first connecting plate to rotate around the first connecting shaft. The rotation of the second connecting shaft causes the second connecting plate to rotate again after the rotation of the first connecting plate. This two-movement operation fully opens the skylight.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4. This utility model provides a technical solution: a fireproof and noise-reducing skylight includes a skylight frame 11, a limiting groove 12 is provided at the bottom of the skylight frame 11, and a first connecting shaft 19 is connected inside the skylight frame 11; a first connecting plate 10 is connected to one side of the first connecting shaft 19, a second connecting shaft 9 is connected to the other end of the first connecting plate 10, a second connecting plate 8 is connected to the other end of the second connecting shaft 9, another first connecting shaft 19 is installed at the other end of the second connecting plate 8, and is connected to the inner wall of the limiting frame 18; a double-layer laminated fireproof glass 16 is installed at the top of the skylight frame 11, an ion exchange glass 17 is installed inside the double-layer laminated fireproof glass 16, the limiting frame 18 is located directly below the limiting groove 12, and the limiting frame 18 is fitted inside the limiting groove 12; a thermoplastic elastomer sealing strip 15 is provided on the outside of the limiting frame 18.

[0022] In this embodiment, when the sunroof needs to be opened, the sunroof frame 11 is lifted, and the limiting frame 18 disengages from the limiting groove 12 at the bottom of the sunroof frame 11. Since the sunroof frame 11 and the limiting frame 18 are connected by two sets of first connecting shafts 19, the first connecting shafts 19 connect the second connecting plate 8 to the inside of the limiting frame 18, causing the second connecting plate 8 to rotate around the first connecting shaft 19. The second connecting plate 8 is connected to the first connecting plate 10 via a second connecting shaft 9, causing the first connecting plate 10 to rotate a second time around the second connecting shaft 9. The other end of the first connecting plate 10 is connected to the sunroof frame via another connecting shaft 19. The interior of the 11 allows the skylight frame to rotate again. Through multiple rotations, the skylight frame can be fully opened, thus avoiding the situation where the top-hung opening method causes backflow and obstructs the normal airflow into the room. An ion exchange glass 17 is installed between the double-layered laminated fireproof glass 16. This ion exchange glass 17 has a good blocking effect on low-frequency noise. Combined with the existing double-layered laminated fireproof glass 16, it can further improve the overall sound insulation performance. The use of thermoplastic elastomer sealing strips 15 with high expansion ratio and good flame retardant properties gives it better elasticity and aging resistance, which can maintain a good sealing effect during long-term use and improve air tightness and water tightness.

[0023] Please refer to Figures 1-4. A sunroof base plate 1 is installed at the bottom of the limiting frame 18. A light-shading opening 4 is provided at the bottom of the sunroof base plate 1. A groove 14 is provided on one side of the light-shading opening 4. A telescopic sunshade 7 is provided inside the groove 14. A handle 13 is connected to the bottom of one side of the telescopic sunshade 7.

[0024] In use, when it is necessary to block the light shining into the room from the skylight, the retractable sunshade 7 can be pulled out from the groove 14 on one side of the light-blocking opening 4 by holding the handle 13, so that it extends and blocks the light. The groove 14 allows the retractable sunshade 7 to be stored when it is not necessary to block the light.

[0025] Please refer to Figures 1-4. The bottom of the skylight base plate 1 is connected to a sound-absorbing plate 2, the bottom of the sound-absorbing plate 2 is connected to a fireproof rock wool board 3, the bottom of the fireproof rock wool board 3 is equipped with a window breaker bracket 5, and a window breaker 6 is installed inside the window breaker bracket 5.

[0026] In this solution, the skylight base plate 1 and the limiting frame 18 are fixedly connected, and the sound-absorbing panel 2 is also fixedly connected to the skylight base plate 1. The sound-absorbing panel 2 is made of melamine foam, which is lightweight, has good sound absorption effect, and is fireproof and flame-retardant. It has a significant absorption effect on low and medium frequency noise. The fireproof rock wool board 3 has a low thermal conductivity and can reach the A1 fire rating, which can effectively prevent heat transfer. In case of emergency, the window breaker 6 can be taken out from the inside of the window breaker bracket 5 and broken into the glass, thus ensuring its use in emergency situations.

[0027] In this invention, when those skilled in the art use the device, they first lift the sunroof frame 11, causing the limiting frame 18 to disengage from the limiting groove 12 at the bottom of the sunroof frame 11. Since the sunroof frame 11 and the limiting frame 18 are connected by two sets of first connecting shafts 19, the first connecting shafts 19 connect the second connecting plate 8 to the inside of the limiting frame 18, allowing the second connecting plate 8 to rotate around the first connecting shaft 19. The second connecting plate 8 and the first connecting plate 10 are connected by a second connecting shaft 9, causing the first connecting plate 10 to rotate a second time around the second connecting shaft 9. The other end of the first connecting plate 10 is connected to the sunroof frame via another connecting shaft 19. The interior of frame 11 allows the skylight frame to rotate again. Through multiple rotations, the skylight frame can be fully opened, thus avoiding the situation where the top-hung opening method causes backflow and obstructs the normal airflow into the room. An ion exchange glass 17 is installed between the double-layered laminated fireproof glass 16. This ion exchange glass 17 has a good blocking effect on low-frequency noise. Combined with the existing double-layered laminated fireproof glass 16, it can further improve the overall sound insulation performance. The use of thermoplastic elastomer sealing strips 15 with high expansion ratio and good flame retardant properties gives it better elasticity and aging resistance, which can maintain a good sealing effect during long-term use and improve air tightness and water tightness.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
