Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a unitized curtain wall structure. Background Technology

[0002] With the increasing diversification of modern architectural design, unitized glass curtain walls have been widely used in the construction field due to their aesthetic appeal and ease of construction. However, while achieving architectural aesthetics and functionality, unitized curtain wall structures also face challenges in areas such as sun shading and ventilation, with poor ventilation being a particularly prominent issue.

[0003] Traditional unitized curtain wall structures typically employ a closed design. While this satisfies insulation requirements to some extent, it severely hinders indoor-outdoor air circulation, leading to decreased indoor air quality and increased stuffiness, especially in summer or poorly ventilated environments. Current technologies often use external ventilation structures to improve efficiency; however, these external structures disrupt the overall aesthetics of the curtain wall, clashing with the building's facade design and posing a safety hazard from falling objects.

[0034] Traditional unitized curtain wall structures typically employ a closed design. While this satisfies insulation requirements to some extent, it severely hinders indoor-outdoor air circulation, leading to decreased indoor air quality and increased stuffiness, especially in summer or poorly ventilated environments. Current technologies often use external ventilation structures to improve efficiency; however, these external structures disrupt the overall aesthetics of the curtain wall, clashing with the building's facade design and posing a safety hazard from falling objects.

[0035] This utility model proposes a unitized curtain wall structure.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, the unitized curtain wall structure 100 includes:

[0037] Curtain wall panel 1, with multiple panels spaced at intervals;

[0038] The column profile 2 is provided on the side of the curtain wall panel 1 facing the interior. Each curtain wall panel 1 has a column profile 2 at its end. The two column profiles 2 provided on the ends of two adjacent curtain wall panels 1 facing each other are spaced apart.

[0039] Vertical decorative columns 3 are located on the exterior-facing side of the curtain wall panel 1, and the side of the vertical decorative columns 3 facing the column profile 2 is provided with air guides 31; and

[0040] Decorative buckle plate 4 is provided on both sides of vertical decorative column 3. The two ends of decorative buckle plate 4 are respectively connected to vertical decorative column 3 and curtain wall panel 1, and ventilation hole 41 is provided on decorative buckle plate 4.

[0041] The gap between two adjacent column profiles 2 and the gap between the decorative buckle 4 and the air guide 31 form an air duct 01, and the air duct 01 is connected to the ventilation hole 41.

[0042] In this invention, each curtain wall panel 1 is installed on a corresponding column profile 2, with adjacent column profiles 2 spaced apart. Vertical decorative columns 3 and decorative panels 4 are also provided on the outer side of the curtain wall panel 1. This creates ventilation ducts 01 from the interior to the exterior in the gaps between the two column profiles 2 and between the two adjacent decorative panels 4 and the air guide 31, allowing for faster air exchange and improved indoor air quality. The vertical decorative columns 3 not only enhance the aesthetics of the curtain wall but also form the air ducts 01. The air guide 31 effectively increases the flow area of ​​the air ducts 01, making airflow smoother and reducing air resistance.

[0043] Specifically, the curtain wall panel 1 can be a square glass panel or a solid wood panel, serving to separate indoor and outdoor spaces and support other components. Multiple curtain wall panels 1 are spaced apart, collectively forming the main exterior surface of the unitized curtain wall, preventing external environmental factors (such as wind, rain, dust, etc.) from entering the interior. The column profile 2 can be made of aluminum alloy or other materials, and its dimensions must be compatible with the thickness of the curtain wall panel 1 to provide vertical support for the curtain wall panel 1. The structure of the vertical decorative column 3 is not specifically limited; it can be butterfly-shaped, T-shaped, etc., as long as it has a guide structure that can increase the width of the air duct 01. The decorative panel 4 can be a trapezoidal plate structure. The ventilation hole 41 is the outlet or inlet for the exchange of air between the air duct 01 and the indoor and outdoor air. The shape of the ventilation hole 41 is not specifically limited; it can be square, round, or triangular, etc. When there is a pressure difference between indoors and outdoors, air enters and exits through the ventilation hole 41, flows within the air duct 01, and thus achieves the exchange of indoor and outdoor air. It should be noted that one end of the decorative buckle plate 4 is connected to the vertical decorative column 3, and the other end is connected to the curtain wall panel 1. The decorative buckle plate 4 and the vertical decorative column 3 can be connected by snap-fit ​​or threaded connection, etc. The decorative buckle plate 4 and the curtain wall panel 1 can be connected by connecting strip or adhesive.

[0044] In the embodiments of this utility model, please refer to Figure 3The air guide section 31 has a beveled edge, and the air guide section 31 and the decorative panel 4 are inclined to form an opening 02. The diameter of the opening 02 increases progressively in the direction towards the column profile 2. The opening 02 is the diameter in the direction in which the two curtain wall panels 1 are arranged side by side. For example, the diameter of the opening 02 near the vertical decorative column 3 is 0.1 meters, while the diameter of the opening 02 near the column profile 2 is 0.3 meters. The beveled design reduces the space occupied by the vertical decorative column 3 in the air duct 01, thereby increasing the actual airflow area in the air duct 01 and improving the ventilation effect of the entire unit curtain wall structure 100.

[0045] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The decorative panel 4 is inclined towards the vertical decorative column 3, with an angle of 35° between it and the horizontal plane. This arrangement, combined with the inclined side of the air guide 31 and the resulting opening 02 structure, further optimizes the inlet shape of the air duct 01, enabling it to guide airflow vertically as well. When air enters the air duct 01, the inclined decorative panel 4 prevents some external debris (such as larger particles like leaves and dust) from directly entering, providing a filtering effect. For example, in strong winds, the inclined decorative panel 4 better resists lateral forces generated by the wind, reducing the possibility of structural deformation.

[0046] In embodiments of this invention, the angle between the decorative panel 4 and the air guide 31 ranges from 30° to 80°. Within this angle range, airflow can be guided more precisely. When the angle is 30°, air entering the duct 01 is guided at a relatively gentle angle, suitable for collecting more air into the duct 01 in a light breeze. As the angle increases to 80°, under stronger winds, air can enter the duct 01 more directly, and due to the change in angle, the airflow direction and velocity distribution within the duct 01 can be better controlled. For example, in the curtain wall structure of high-rise buildings, wind conditions vary at different heights; this angle range can adapt to wind conditions at different heights, allowing the ventilation system to maintain good operating performance under various wind conditions.

[0047] In this embodiment of the invention, the air guide 31 has an arc-shaped edge that protrudes away from the column profile 2. For example, the arc can be approximated as part of a circular arc with a radius of 0.5 meters, which can guide the airflow more smoothly. Compared with a straight edge, the arc-shaped edge can reduce airflow resistance. When air flows through the air guide 31, the arc-shaped surface allows the air to flow naturally along the curve, avoiding turbulence at sharp edges.

[0048] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The ventilation holes 41 are evenly arranged in an array on the decorative panel 4, and the ventilation holes 41 are either honeycomb holes or oval holes. The specific array arrangement is not limited; for example, it can be a rectangular array or a circular array. The shape of the ventilation holes 41 can be honeycomb holes or oval holes, or other rhomboid or triangular shapes, which users can set according to their actual needs. When air passes through the honeycomb holes, energy loss is reduced, making airflow smoother. The design of the long and short axes of the oval holes also helps guide air to flow in a specific direction, reducing turbulence at the hole opening. Because the ventilation holes 41 are evenly arranged in an array, whether honeycomb holes or oval holes, air can be evenly entered and exited on the decorative panel 4, making the air pressure distribution within the air duct 01 more uniform, thus achieving a more stable and uniform ventilation effect.

[0049] In this embodiment of the invention, the decorative panel 4 is also provided with a filter screen (not shown), which is detachably installed inside the ventilation hole 41. For example, the filter screen can be detachably installed through a slot and block structure or a threaded connection, making it convenient for cleaning and replacement. The filter screen can effectively filter dust, impurities and other particulate matter in the air. When air passes through the ventilation hole 41, it first passes through the filter screen, which can intercept tiny particles such as dust and pollen, thereby improving the cleanliness of the air entering the room.

[0050] In the embodiments of this utility model, please refer to Figure 3 A connecting strip 5 is provided at the connection between the curtain wall panel 1 and the column profile 2. The connecting strip 5 can be silicone sealant or epoxy resin sealant, which ensures both adhesion and excellent sealing. The connecting strip 5 can fill the tiny gaps at the connection between the curtain wall panel 1 and the column profile 2, preventing the leakage of external air, rainwater, dust, etc. The elasticity of the connecting strip 5 can also provide shock absorption and buffering between the curtain wall panel 1 and the column profile 2. When subjected to external forces such as wind and earthquakes, the curtain wall panel 1 may undergo slight displacement. The connecting strip 5 can absorb the energy generated by these displacements, reduce hard impacts between the panel and the profile, and protect the structural integrity of both.

[0051] In the embodiments of this utility model, please refer to Figure 3The decorative panel 4 and the curtain wall panel 1 are connected by a sealing strip 6. The sealing strip 6 can be made of EPDM or other rubber strips. It ensures a tight seal between the decorative panel 4 and the curtain wall panel 1. For example, in strong winds, air will not enter the room through the connection between the decorative panel 4 and the curtain wall panel 1, thus improving the comfort and stability of the indoor environment. The sealing strip 6 also buffers the external forces that the decorative panel 4 may experience, extending the service life of the structure. Furthermore, one end of the sealing strip 6 has a tongue, and the end of the decorative panel 4 near the sealing strip 6 has a groove. The groove and tongue work together to improve connection stability. The sealing strip 6 makes the connections between the curtain wall panel 1 and the column profile 2, and between the decorative panel 4 and the curtain wall panel 1, smoother and neater. From an aesthetic perspective, there are no obvious gaps or abrupt changes, enhancing the overall aesthetics of the unitized curtain wall.

[0052] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The vertical decorative column 3 is provided with a snap-fit ​​protrusion 32, and the decorative buckle plate 4 is provided with a snap-fit ​​strip 42. The snap-fit ​​strip 42 has a snap-fit ​​recess 421 on the side near the decorative buckle plate 4. The snap-fit ​​protrusion 32 and the snap-fit ​​recess 421 snap together. The snap-fit ​​protrusion 32 can be a trapezoidal protrusion, and the snap-fit ​​recess 421 is a matching trapezoidal groove. The snap-fit ​​strip 42 is a long strip structure. During installation, the connection can be completed simply by aligning the snap-fit ​​protrusion 32 with the snap-fit ​​recess 421 and gently snapping it in. There is no need for complicated bolt connections or welding operations, which greatly improves the installation efficiency and avoids the abruptness caused by using bolts and other connectors.

[0053] In the embodiments of this utility model, please refer to Figure 3 The column profile 2 includes a central column 21 and male-female composite columns. The male-female composite columns include a male column 22 and a female column 23 that interlock with each other. In two adjacent column profiles 2 of two adjacent curtain wall units, one column profile 2 is a male-female composite column, and the other column profile 2 is a central column 21. For example, the male column 22 may be provided with a protruding interlocking part, and the female column 23 may be provided with a corresponding groove, allowing them to be tightly interlocked. The central column 21 has an independent structure, which cooperates with the male-female composite columns to construct the support structure of the curtain wall. The male column 22 and female column 23 of the male-female composite columns can be easily interlocked on the construction site, reducing the difficulty and time of installation. If a part of the male-female composite column (male column 22 or female column 23) is damaged, it can be relatively easy to replace it individually due to the interlocking structure.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and 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.
