Description

Technical Field

[0001] This invention belongs to the field of building engineering, and in particular relates to a curtain wall module and method for adaptively reducing positive and negative wind pressure. Background Technology

[0002] As buildings evolve towards greater height, more complex shapes, and lighter structures, the wind forces acting on their surfaces become more complex and unpredictable. Traditional building curtain walls typically employ a static, rigid design philosophy, based on fixed wind tunnel test data or maximum wind pressure values ​​specified in standards. This design approach has significant drawbacks: on the one hand, to withstand extreme gusts in rare cases, the entire curtain wall system often needs to be over-strengthened, leading to material waste and soaring construction costs; on the other hand, wind in reality is constantly changing, and localized eddies, corner effects, or slit winds can generate instantaneous positive or negative pressures far exceeding design values, posing a significant threat to curtain wall panels and connectors. In particular, negative wind pressure (suction) can easily cause curtain wall components to be sucked out and detach, leading to safety accidents. Existing solutions typically reduce surface wind pressure by installing fixed vents or deflectors, but both have obvious limitations. Fixed vents cannot be precisely adjusted according to actual wind conditions, while external devices such as deflectors are not only difficult to adjust for negative wind pressure but also aesthetically unappealing. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention aims to provide a building curtain wall module and method that can adaptively reduce positive and negative wind pressure. It is a movable curtain wall module solution that combines the ability of a building to autonomously change its shape with wind pressure and adaptively reduce extreme negative wind pressure.

[0004] This module can automatically open or undergo controlled deformation based on changes in external wind pressure, effectively adjusting the wind load on the building surface. In light or no wind conditions, the curtain wall module remains sealed, ensuring the integrity and airtightness of the building envelope. Under moderate wind conditions, the baffles and spring system within the module produce slight elastic deformation, forming a dynamic wave-like profile on the building's exterior surface. This helps guide airflow, reduce localized wind pressure concentration, and serves a decorative function for the facade envelope. When encountering strong winds, the system further increases its deformation, significantly reducing the peak negative wind pressure on the building's exterior surface through its structural energy absorption characteristics, thereby improving overall wind resistance and structural durability.

[0005] The technical solution of this invention is as follows: I. A curtain wall module for adaptively reducing positive and negative wind pressure in buildings: The curtain wall module is attached to the outer surface of the building. Each curtain wall module includes a movable plate, a frame, a spring, and a guide plate. The frame is a polygonal frame with both ends connected. One end of the frame is fixedly connected to the inner curtain wall of the building, and a movable plate is set at the other end of the frame. The movable plate is connected to the inner curtain wall of the building via a spring. The sides of the movable plate and the sides of the frame are connected by guide plates. In a single curtain wall module, wind pressure is controlled by a movable plate and springs. The movable plate moves in a direction perpendicular to the interior curtain wall of the building to adjust the wind pressure, and the springs are stretched or compressed to reduce positive and negative wind pressure.

[0006] It includes multiple springs that are evenly distributed and connected between the movable plate and the interior curtain wall of the building. One end of each spring is fixedly connected to the interior curtain wall of the building, and the other end is fixedly connected to the movable plate.

[0007] The movable plate is arranged perpendicular to the frame axis, and each side of the movable plate is vertically fixedly connected to a guide plate, which extends into the frame and is slidably and tightly connected to the inner wall of the frame.

[0008] The cross-section of the frame is a polygon such as a rectangle, square, or hexagon.

[0009] The shape and size of the movable plate are the same as the cross-section and size of the frame.

[0010] In a single curtain wall module, a wind pressure absorption and regulation system is formed by combining springs, movable plates, and guide plates. The frame is a quadrilateral frame. Each curtain wall module contains four springs and one movable plate. One end of each of the four springs is fixedly connected to four spaced points on the interior curtain wall of the building, and the other end of each of the four springs is connected to four spaced points on the movable plate. The four points fall at the four corners, and the four springs are arranged parallel to each other.

[0011] The wind energy absorption and regulation system consists of springs and movable plates. Under no wind pressure, the plates are in equilibrium and remain stationary on the outermost side of the frame, while the curtain wall modules remain internally closed in this condition. If the entire building facade is under no wind pressure, all external curtain wall modules remain closed, and the entire building facade remains sealed, ensuring the integrity and airtightness of the building envelope. It includes multiple curtain wall modules, which are arranged in an array on the exterior surface of the building. Each curtain wall module is fixedly connected to the building surface through its own frame.

[0012] II. A building adaptive method for reducing positive and negative wind pressure, the method comprising: Individual curtain wall modules adjust wind pressure by facing the wind directly through movable panels; Under positive wind pressure, the movable panel moves towards the inner side of the inner curtain wall, and the four springs are compressed to store wind energy. At this time, a gap is formed between the movable panel and the opening on the end face of the frame, and some high-pressure airflow can enter the pressure chamber inside the frame through the gap, and then be discharged laterally to the adjacent low-pressure area or the buffer space inside the building, thereby guiding the airflow and weakening the local wind pressure concentration. Under negative wind pressure, the movable panel moves away from the inner curtain wall and the four springs are stretched to store wind energy; at the same time, the air inside the frame is drawn in through the opening on the end face of the frame and directly replenishes the negative pressure area, thereby balancing the pressure difference between the inside and outside, greatly weakening the adsorption force on the curtain wall module and preventing the structure from being damaged. When there is no wind pressure, the movable plate stays at the end of the frame, and the four springs naturally extend without being compressed or stretched.

[0013] Multiple curtain wall modules are arranged closely and evenly on the building surface to form an integral module array, thereby decorating and regulating the wind pressure on the entire exterior surface of the building. The spring inside a single curtain wall module at the positive wind pressure is compressed, causing the movable plate to move inward. The springs inside a single curtain wall module at the negative wind pressure are stretched, causing the movable plate to move inward. In areas with no wind pressure, the springs and movable plates within a single curtain wall module remain stationary.

[0014] This invention features an array of frames arranged perpendicular to the building's outer surface. Each frame contains a movable baffle-spring system, with the baffles fixed to the building's inner surface by springs. Initially, the movable baffle-spring system is flush with the outermost edge of the frame. When positive wind pressure applies, the springs are compressed, causing the baffles to move inward. When negative wind pressure applies, the springs are stretched, causing the baffles to move outward. Under normal wind conditions, the baffle-spring system within each frame moves inward and outward with the application of positive or negative wind pressure, resulting in a building's outer surface exhibiting a shape that changes with wind pressure, achieving an aesthetically pleasing curtain wall facade. Typhoons or strong winds typically exert extreme negative wind pressure on buildings. When each frame is subjected to extreme negative wind pressure, the baffle-spring system protrudes from the building surface. Research indicates that this surface protrusion reduces the negative wind pressure on the building surface, thus adaptively reducing the risk of damage from extreme negative wind pressure.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. It requires no sensors, controllers or external power, and uses wind pressure itself as the driving energy, achieving a passive response. It can automatically adjust its response according to the actual wind pressure conditions and is equally reliable in extreme weather.

[0016] 2. Under strong winds, many existing pressure reduction systems struggle to cope with excessive negative wind pressure on curtain walls. This invention can effectively address both positive and negative pressure threats simultaneously, enabling dynamic and real-time management of curtain wall loads and significantly improving the wind resistance safety of curtain walls.

[0017] 3. By reducing the load through external curtain wall modules, the overall design wind load value of the building's internal curtain wall system can be reduced, thereby reducing the amount of main structural materials used and the strength requirements of the curtain wall frame, and saving project costs.

[0018] 4. It only activates when the wind pressure exceeds the standard, and remains completely closed when there is no wind pressure, thus maximizing the maintenance of the building curtain wall's comprehensive physical properties such as thermal insulation, heat insulation, sound insulation, and waterproofing.

[0019] 5. This curtain wall module is designed as a standard unit, suitable for new buildings or renovations of existing buildings. The building form, building height, materials and shapes of movable panel components (baffle type, spring material, etc.), curtain wall module size and opening type can be customized according to the characteristics of different buildings.

[0020] 6. The equipment configuration within the module is flexible and versatile. Power generation devices can be installed in the frame module to use the stored wind energy for facade lighting and building power supply.

[0021] 7. In light winds or complex wind conditions, the array of movable panels on the overall facade is in a fluctuating state, forming a wave-like shape when viewed from a distance, thus combining aesthetics and artistry. Attached Figure Description

[0024] The present invention will be described in detail below with reference to specific implementation examples. These examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0025] like Figure 1 As shown, curtain wall module 2 is attached to the outer surface of building 1, such as... Figures 2-4 As shown, a single curtain wall module 2 includes a movable plate 3, a frame 4, a spring 5, and a guide plate 7. The frame 4 is a polygonal frame with both ends connected and hollow inside. One end of the frame 4 is fixedly connected to the inner curtain wall 6 of the building 1, and a movable plate 3 is set at the other end of the frame 4. The movable plate 3 is connected to the inner curtain wall 6 of the building 1 via the spring 5. The sides of the movable plate 3 and the sides of the frame 4 are connected by the guide plate 7. Guide plates are set around the movable plate to prevent the movable plate from rotating.

[0026] In a single curtain wall module 2, the wind pressure is controlled by a movable plate 3 and a spring 5. The movable plate 3 moves in a direction perpendicular to the interior curtain wall 6 of the building to adjust the wind pressure, and the spring 5 is stretched or compressed to reduce positive and negative wind pressure.

[0027] The size of a single curtain wall module is determined by the dimensions of the building facade or can be freely selected according to the facade decoration requirements. The curtain wall module is supported by a frame and connected to the interior curtain wall of the building. Each curtain wall module contains multiple springs and a movable plate. The number and position of the springs can be freely selected according to the actual situation.

[0028] It includes multiple parallel springs 5, which are evenly distributed and connected between the movable plate 3 and the inner curtain wall 6 of the building 1. One end of each spring 5 is fixedly connected to the inner curtain wall 6 of the building 1, and the other end is fixedly connected to the movable plate 3.

[0029] The movable panel 3 is arranged perpendicular to the axial direction of the frame 4, that is, parallel to the inner curtain wall 6 of the building 1. Each side of the movable panel 3 is vertically and fixedly connected to a guide plate 7. The guide plate 7 extends into the frame 4 and is slidably and tightly connected to the inner wall of the frame 4. The guide plate 7 is perpendicular to the movable panel 3 and parallel to the side of the frame 4.

[0030] The surrounding guide plates 7 are used to prevent the movable plate 3 from rotating when it is in motion.

[0031] like Figure 10As shown, the cross-section of frame 4 is a polygon such as a rectangle, square, or hexagon. Furthermore, the shape and dimensions of the movable plate 3 correspond to the cross-section and dimensions of frame 4.

[0032] Spring 5 is connected to the interior curtain wall 6 of the building. The individual curtain wall modules 2 are divided by the equally spaced array of the frame 4. The size of the individual curtain wall modules 2 is arranged equally according to the size of the interior curtain wall 6 of the building. The curtain wall modules 2 can be freely selected according to the shape of the building facade.

[0033] In a single curtain wall module 2, a wind pressure absorption and regulation system is formed by combining springs 5, movable plates 3 and guide plates 7. The frame 4 is a quadrilateral frame. Each curtain wall module 2 contains four springs 5 ​​and one movable plate 3. One end of each of the four springs 5 ​​is fixedly connected to four spaced points of the inner curtain wall 6 of the building 1. The other end of each of the four springs 5 ​​is connected to four spaced points of the movable plate 3. The four points fall at the four corners, and the four springs 5 ​​are arranged parallel to each other.

[0034] like Figures 5-6 As shown, the structure includes multiple curtain wall modules 2, which are arranged in an array on the outer surface of the building 1. Each curtain wall module 2 is fixedly connected to the surface of the building 1 through its own frame 4. The multiple curtain wall modules 2 are evenly arranged on the surface of the building 1 to form a module array, forming a whole on the outer surface of the building 1, which is used for decoration and to regulate the wind pressure on the entire outer surface of the building 1.

[0035] The working process under the structure of this invention is as follows: Each individual curtain wall module 2 adjusts the wind pressure by facing the wind directly through the movable plate 3: Under positive wind pressure, the air pressure inside the curtain wall module is lower than that outside. At this time, the pressure difference causes the movable plate 3 to move closer to the inner side of the inner curtain wall 6, and the four springs 5 ​​are compressed to store wind energy. At this time, a gap is formed between the movable part of the movable plate 3 and the opening of the panel end face of the frame 4. Some high-pressure airflow can enter the pressure chamber inside the frame 4 through the gap, and then be discharged laterally to the adjacent low-pressure area or the buffer space inside the building, thereby guiding the airflow and weakening the local wind pressure concentration. Each chamber corresponds to a geometric area divided by a frame. The spaces between adjacent chambers are ventilated blank areas except for the guide plate. When the movable plate extends or retracts, airflow can flow to the adjacent area through the vent.

[0036] Under negative wind pressure, the air pressure inside the curtain wall module is relatively higher than that outside. This pressure difference will cause the movable panel 3 to move away from the inner curtain wall 6 and outward, and the four springs 5 ​​will be stretched to store wind energy; at the same time, the air inside the frame 4 is quickly drawn in through the opening on the end face of the panel of the frame 4 and directly replenishes the negative pressure area, thereby quickly balancing the internal and external pressure difference, greatly weakening the adsorption force on the curtain wall module and preventing the structure from being damaged. When there is no wind pressure, the movable plate 3 stays at the port of the frame 4 and is just on the edge side, and the four springs 5 ​​naturally extend without being compressed or stretched.

[0037] As the positive or negative pressure gradually decreases, the movable plate is pushed to maintain the balance of wind pressure on both sides until a new equilibrium is reached.

[0038] In light or complex wind conditions, the building facade may be under different wind pressure states. In positive pressure areas, the movable panels are balanced inside the frame; in negative pressure areas, they are balanced outside the frame; and in areas with no wind pressure, they remain in place. The staggered arrangement of the movable panels across the entire facade not only reduces wind pressure but also enhances aesthetics and artistic appeal.

[0039] Multiple curtain wall modules 2 are arranged closely and evenly on the outer surface of the inner curtain wall 6 of building 1 to form an integral module array, thereby decorating and regulating the wind pressure on the entire outer surface of building 1. The spring 5 inside the single curtain wall module 2 at the positive wind pressure is compressed, and the movable plate 3 moves inward; The spring 5 inside the single curtain wall module 2 at the negative wind pressure is stretched, and the movable plate 3 moves inward; In a single curtain wall module 2 without wind pressure, the spring 5 and the movable plate 3 are both stationary.

[0040] In this way, the movable panels 3 are arranged in an alternating pattern on the outer surface of the building, which not only absorbs the positive and negative wind pressure on the surface of the building 1 and reflects the wind pressure distribution characteristics of the building surface, but also allows the movable panels 3 to move with the wind at low wind speeds, thus taking into account the aesthetics of the building facade.

[0041] Example 1: Basic Implementation refer to Figures 1 to 5 This invention provides a curtain wall module for adaptively reducing positive and negative wind pressure in buildings. As a standard unit, its frame size can be, for example, 1200mm × 1200mm. The module mainly includes, from the exterior to the interior, a movable panel 3, a frame 4, a guide plate 7 and a spring 5 within the frame 4, and an inner curtain wall 6.

[0042] The movable panel 3 and the guide panel 7 can be made of 4mm thick aluminum single panel or fiber reinforced composite material panel, and their surfaces can be treated with fluorocarbon spraying or other treatments according to architectural aesthetic requirements.

[0043] Four springs 5 ​​are installed in each curtain wall module, evenly distributed on the four sides of the movable panel 3. The compression force of each spring 5 is precisely calculated and set so that the movable panel 3 is not subjected to preload under normal conditions, thus remaining outside the frame 4 in the absence of wind pressure. The stiffness coefficient and initial compression of the springs can be adjusted according to the design wind pressure value.

[0044] The inner sides of the movable plate 3 and the frame 4 together enclose a pressure chamber. The balance within the chamber can be adjusted according to the magnitude of the external positive and negative pressure.

[0045] The internal support and frame 4 is made of aluminum alloy profiles. It serves not only as the base for mounting the movable plate 3 and spring 5, but also as a reliable connection to the main building structure via sealing strips, ensuring the overall watertightness and airtightness of the module. Working principle and process: Normal state: such as Figure 1 As shown, when the external wind speed is low, the preload of spring 5 is 0, the movable plate 3 is tightly attached to the outside of frame 4, and the curtain wall module has excellent thermal insulation and sound insulation performance. Figure 2 This indicates that the curtain wall module is in a state of no wind pressure.

[0046] Positive air pressure compression state: such as Figure 3 As shown, when strong winds cause the positive pressure on the outer surface of the module to exceed the internal pressure of the curtain wall module, the pressure acting on the movable plate 3 compresses the spring 5 inward, pushing the movable plate 3 to move towards the interior. At this time, a gap is formed between the movable plate 3 and the frame 4. The external high-pressure airflow enters the curtain wall module 2 through the gap. After the wind pressure weakens, the spring 5 pushes the movable plate 3 back to its original position, resealing it.

[0047] Negative wind pressure balance state: such as Figure 4 As shown, when a strong negative pressure suction is formed on the outer surface of the module, the air pressure inside the curtain wall module 2 is relatively higher than that outside. This pressure difference also "pulls" the movable panel 3 towards the outside. Outside air is rapidly drawn into the curtain wall module 2 through the gaps created by the movement of the movable panel, directly replenishing the negative pressure zone on the curtain wall surface, thus instantly balancing the internal and external pressure difference. According to literature research, exterior facade decorations can effectively reduce the negative wind pressure on building facades.

[0048] Figure 5 This is a rendering showing the layout of the curtain wall modules arranged in a row. Figure 6 This is a diagram representing the effect of the array arrangement from a top-down perspective. Figure 7 This represents the wind pressure distribution from a top-down perspective. Figure 8 Representative at Figure 7 A schematic diagram showing the position of the movable plate under wind pressure distribution. Figure 9 This is a rendering of the entire building facade covered with curtain wall modules.

[0049] Example 2: Variant Implementation In this embodiment, to meet the decorative requirements of different building shapes, the curtain wall frame, the shape of the movable panel, and the position of the springs can be optimized. For example... Figure 10 , Figure 11 As shown, schematic diagrams of square, rectangular, and hexagonal arrays are provided, and the module shape can be selected according to the actual facade shape.

[0050] The integral movable panel 3 and fixed frame 4 are replaced with hexagonal ones. The movable panel 3 is assembled from louvers according to the characteristics of the surrounding wind environment and aesthetic requirements. Each louver is hinged to the frame by a spring. With this design, changes in local wind pressure can trigger the movement of the louvers in the corresponding area, resulting in a more sensitive response and stronger targeting of local extreme wind pressures (such as angular vortices). The displacement of the louvers can change continuously with the increase of wind pressure, achieving more linear wind pressure regulation.

[0051] Other structural components can also be freely selected. In addition to spring 5, the displacement control device can also employ a mechanical gear system or a counterweight lever system. Besides metal, the frame material can also use high-strength engineering plastics or composite materials to reduce weight and cost. For applications requiring extremely high airtightness, elastic sealing strips can be added to the contact surfaces between the cover plate or louvers and the panel.

[0052] Installation and Use This curtain wall module can be prefabricated into complete unit panels in the factory. After being transported to the site, it is installed on the main building structure using the same hook or screw connection method as conventional curtain wall units, through its internal support frame. When multiple modules are installed side by side, their sides should be aligned to form a continuous pressure balance system.

[0053] As can be seen from the implementation, this invention can, on the one hand, achieve the aesthetic purpose of the baffle moving inward and outward on the building surface in response to positive and negative wind pressure under normal wind conditions; on the other hand, by having each baffle-spring system protrude from the building surface under extreme negative wind pressure, it adaptively reduces the negative wind pressure on the building's outer surface, thereby reducing the risk of wind pressure damage to the building surface; therefore, this device takes into account both aesthetics and safety and is suitable for the facades of various buildings.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
