Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain wall units, and in particular to a concealed opening fan curtain wall unit for high-rise towers that is integrated with the exterior design. Background Technology
[0002] Curtain walls are the most common form of exterior wall used in modern high-rise and large public buildings. They cover the outermost layer of a building, separating the interior from the exterior, protecting against wind, rain, temperature changes, noise, and dust, and providing a safe and comfortable environment for the interior. Furthermore, curtain walls are one of the most important aesthetic features of a building, significantly influencing its overall visual effect and serving as a crucial decorative element. However, in the design of many high-rise office buildings, in pursuit of a simple, modern, and integrated visual effect, operable windows are eliminated, relying on central air conditioning systems to meet indoor ventilation needs, increasing energy consumption and operating costs. Additionally, occupants cannot open windows according to personal preferences or weather conditions, lacking a sense of control over their environment and prone to developing "sick building syndrome" (SBS) due to prolonged exposure to enclosed spaces, resulting in poor comfort.

[0022] This utility model proposes a concealed, openable curtain wall unit for high-rise towers that integrates with the building's appearance.
[0023] like Figure 1 and 2 As shown in Embodiment 1 of this utility model, the concealed operable high-rise tower curtain wall unit integrated with the exterior includes connecting components, a supporting frame, an inward-opening window 4, and an external decorative structure. Specifically, the connecting components are embedded in the main structure of the building, and the supporting frame is connected to the connecting components via bolts, hangers, and other connectors. Since the connecting components themselves and their connection to the supporting frame are mature existing technologies, they will not be described in detail in this embodiment. Furthermore, the inward-opening window 4 is installed on the inner side of the supporting frame, and the external decorative structure covers the outer side of the supporting frame.
[0024] The exterior decorative structure can conceal and hide the inward-opening casement window 4 located on its inner side, preventing the casement window 4 from being directly exposed on the building's exterior facade. It also prevents the risk of the casement window 4, people, and objects falling. Furthermore, the exterior decorative structure can create a simple, modern, and integrated visual effect with other structures on the building's exterior surface, such as the fixed window 5 and aluminum panel wing 6 of this patent, ensuring the overall purity and modernity of the building's facade. In addition, the inward-opening window 4 can meet the indoor ventilation needs by opening it, thereby reducing energy consumption and operating costs. Moreover, indoor occupants can open the window for ventilation according to personal preferences or weather conditions, ensuring a sense of control over the environment and reducing the occurrence of "sick building syndrome" (SBS) caused by prolonged exposure to enclosed spaces, thus effectively improving comfort.
[0025] In this embodiment, the inward-opening casement window 4 is located at the lower part of the supporting frame, and the sill height of the inward-opening casement window 4 is within the range of 80mm-600mm, preferably within the range of 100mm-300mm. Additionally, an easy-to-operate opening handle 41 is provided on the inner side of the inward-opening casement window 4. Setting the sill height of the inward-opening casement window 4 within the above-mentioned range improves the convenience for indoor occupants to open the window. Furthermore, the aforementioned external decorative structure is an aluminum mesh grille 7. In other embodiments, the external decorative structure can be a stainless steel woven mesh or a GFRC perforated panel, which can serve to conceal and hide the inward-opening casement window 4, preventing it from being directly exposed on the building's exterior facade. (GFRC is an abbreviation for Glass Fiber Reinforced Concrete.)
[0026] Specifically, the aforementioned support frame includes a first column 1, a second column 2, a third column 3, and several crossbeams installed or directly embedded in the building through connecting components. The first column 1, the second column 2, the third column 3, and the crossbeams are connected by bolts and other connecting components to form the support frame.
[0027] like Figure 1 and 2 As shown, the concealed operable high-rise tower curtain wall unit, integrated with the exterior design, also includes fixed windows 5 and aluminum panel wing 6. The fixed windows 5, inward-opening windows 4, and the exterior decorative structure and aluminum panel wing 6 are arranged side-by-side. Specifically, after installation, the concealed operable high-rise tower curtain wall unit of this patent forms an alternating pattern with the fixed windows 5, the exterior decorative structure, and the aluminum panel wing 6, creating a simple, modern, and integrated visual effect, ensuring the overall purity and modernity of the building facade. In this embodiment, both the inward-opening windows 4 and the fixed windows 5 use double-glazed laminated LOW-E glass as the panel material ("LOW-E" is an abbreviation for Low Emissivity, meaning low-emissivity glass, which refers to glass with a low-emissivity coating). The hollow layer of the double-glazed LOW-E glass provides excellent thermal insulation performance, the laminate layer enhances safety and impact resistance (especially in high-rise buildings), and the LOW-E coating effectively reflects solar radiation heat, significantly reducing building energy consumption and improving indoor comfort.
[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
