Technical Field

[0001] This utility model relates to the field of building curtain wall decoration technology, and in particular to a U-shaped ventilation device that opens on both sides. Background Technology

[0002] Energy conservation and environmental protection have become two major themes in the world today, and building curtain walls, as the main body of building energy conservation, are no exception. Green curtain wall products have emerged and are receiving increasing attention. Various new energy-saving and environmentally friendly materials, such as LOT-E ​​glass and thermally broken profiles, have been widely used, and double-layer ventilated curtain walls have gradually come into view.

[0003] However, with the development of curtain wall technology, architects are not only pursuing the integrity of the curtain wall facade but also continuously seeking comfort in the interior environment. However, to ensure natural ventilation, conventional curtain walls inevitably require operable windows on the exterior facade, thus disrupting the overall aesthetic and making the facade appear uneven. Furthermore, in recent years, incidents of operable curtain wall panels falling have occurred frequently, raising questions about the safety of curtain walls and making it crucial to improve the safety of curtain wall systems. Utility Model Content

[0004] The purpose of this invention is to provide a U-shaped ventilation device that opens on both sides, so as to solve the problems encountered in the above-mentioned background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A U-shaped ventilation device with double-sided opening includes a front vertical frame, a rear vertical frame, and a mounting frame. Two front vertical frames and two rear vertical frames are provided and installed in the curtain wall. Tempered glass is installed between the inner sides of the two front vertical frames. The front vertical frames are connected to the rear vertical frames through the mounting frame to form a U-shaped structure. A perforated lightweight metal plate is installed on the inner side of the mounting frame, and a window sash is rotatably connected to the outer side of the mounting frame.

[0007] In the above scheme, the interior of the mounting frame is filled with thermal insulation rock wool, and a cavity is reserved for installing the window sash; the lightweight metal plate is clamped on the inner side of the mounting frame, and the outer surface of the lightweight metal plate is uniformly provided with through holes.

[0008] In the above solution, an insect-proof mesh is provided on the inner side of the mounting frame near the lightweight metal plate. The window sash is rotatably connected to the reserved cavity via a hinge. A lock that engages with the window sash is provided on one side of the mounting frame, and the working end of the lock has a pin.

[0009] In the above design, a slot is provided between the bottom of the two front vertical frames, and the tempered glass is inserted into the slot. There are two slots that are parallel to each other, and a partition strip is provided between the side ends of the two tempered glass panes. A stop is installed on the outer side of the partition strip, and the two sides of the stop press the partition strip so that it is tightly attached to the inner side of the two tempered glass panes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: After the top and bottom of the front vertical frame 1 are connected to the rear vertical frame 2 through the mounting frame 31, the whole structure forms a U-shaped structure, which is suitable for installation near the window of a U-shaped wall to achieve a flat exterior of the curtain wall. A window sash is rotatably connected to the outside of the mounting frame. By opening the window sash, ventilation can be achieved. Since the window sash is located inside the inner floor of the curtain wall, it has the function of preventing falls from height. A lightweight metal plate is clamped on the inner side of the mounting frame, and the outer surface of the lightweight metal plate is evenly perforated. When the window sash is opened, airflow exchange between the inside and outside is achieved for ventilation. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, a U-shaped ventilation device with double-sided opening includes a front vertical frame 1, a rear vertical frame 2, and a mounting frame 31. In implementation, two front vertical frames 1 and two rear vertical frames 2 are each provided and installed in the curtain wall, and are fixed to the decorative curtain wall by clips or screws. Both the front vertical frame 1 and the rear vertical frame 2 are frame structures with many sealing components installed inside to isolate the connection points.

[0023] Tempered glass 4 is installed between the inner sides of the two front vertical frames 1 to seal the interior of the curtain wall, improve airtightness and provide thermal insulation. In practice, tempered glass 4 is medium-transmittance double silver LoW-E insulated ultra-clear tempered glass.

[0024] During installation, a slot 21 is provided between the bottoms of the two front vertical frames 1, and the tempered glass 4 is inserted into the slot 21. The middle section of the slot 21 has the same thickness as the tempered glass 4, and the side end of the slot 21 can be larger than the thickness of the tempered glass 4, so that the tempered glass 4 can be placed into the slot 21 using a clamping tool.

[0025] As a preferred option, please refer to Figure 6 Two parallel slots 21 are provided, each corresponding to a tempered glass panel 4, providing double protection and good sound insulation. A partition strip 41 is provided between the sides of the two tempered glass panels 4 to separate them and ensure a tight fit between them, preventing the low precision of the slots 21 from affecting the installation accuracy of the tempered glass panels 4. A stop block 42 is installed on the outer side of the partition strip 41. The two sides of the stop block 42 press the partition strip 41 tightly against the inner side of the two tempered glass panels 4. The stop block 42's protruding top portions on both sides further tighten the partition strip 41, allowing for better control of the distance between the two tempered glass panels 4 and ensuring a good airtight space in between.

[0026] The top and bottom of the front vertical frame 1 are connected to the rear vertical frame 2 via the mounting frame 31, forming a U-shaped structure. For aesthetic purposes, glass can also be installed on the outward-facing side of the curtain wall, making it appear flat from the outside. Other windows on the curtain wall can be opened when ventilation is needed. Plates are also installed at the top and bottom of this U-shaped ventilation device to seal the upper and lower openings of the U-shaped structure. Alternatively, the upper and lower sides can be used as ventilation openings, connected to ventilation ducts, and sealed to a certain extent. A perforated lightweight metal plate 3 is installed on the inner side of the mounting frame 31. The lightweight metal plate 3 can be any of copper, stainless steel, aluminum, or aluminum alloy, with aluminum being preferred due to its low hardness, ease of installation, and strong stamping and ductility, making it easy to manufacture. A window sash 5 is rotatably connected to the outer side of the mounting frame 31, allowing ventilation by opening the window sash 5.

[0027] Mounting frame 31 requires fluorocarbon coating. The fluorocarbon-coated outer surface exhibits excellent resistance to fading, frosting, corrosion, and UV radiation, as well as strong crack resistance and the ability to withstand harsh weather conditions, making it ideal for use in ventilated curtain walls. Please refer to [link / reference]. Figure 5 The interior of the mounting frame 31 is filled with insulating rock wool 33, and a cavity is reserved for installing the window sash 5. The window sash 5 is rotatably connected to the reserved cavity via a hinge 52. A lightweight metal plate 3 is clipped onto the inner side of the mounting frame 31, and the outer surface of the lightweight metal plate 3 is evenly provided with through holes, so that when the window sash 5 is opened, airflow exchange between the inside and outside can be achieved for ventilation.

[0028] Please see Figure 5 An insect screen 32 is provided on the inner side of the mounting frame 31 near the lightweight metal plate 3 to prevent mosquitoes from entering during ventilation and to filter out floating debris blown by the wind. Please refer to [link / reference]. Figure 4 A lock 51 is provided on one side of the mounting frame 31, which engages with the window sash 5. The working end of the lock 51 is provided with a pin 53. The lock 51 can be an aluminum alloy push-button concealed door lock, with the lock face embedded in the mounting frame 31 and its outer wall flush with the outer wall of the mounting frame 31. The lock 51 can be a push-button door lock commonly found on fire hydrant boxes, or a door lock on electrical cabinets that requires a key to rotate to open. Rotating the key causes the pin 53 to disengage from the slot 11, thereby opening the window sash 5.
