Description

Technical Field

[0001] This invention belongs to the field of green building technology, specifically relating to a passive energy-saving building facade chord wave guiding external envelope system. Background Technology

[0002] For large-scale super-limit buildings (such as super high-rise buildings and irregularly shaped buildings), they often have characteristics such as large sites, high floors, and significant setbacks from surrounding areas. This provides designers with a focus for studying energy-saving scenarios for their super high-rise facades and irregularly shaped facades. However, traditional building facades often only pay attention to controlling the site's wind direction, such as avoiding the creation of windless zones, appropriately controlling the wind speed and wind perception requirements at the pedestrian height (1.5m), and avoiding excessive wind pressure differences in doors, windows, and curtain walls, which could affect airtightness, etc.

[0003] Specifically, such as Figure 7 As shown, traditional building facades have the following shortcomings in terms of wind energy recovery:

[0004] 1. The natural wind field is disordered, and the wind direction is randomly dispersed. It mainly acts on the building curtain wall and is manifested in the form of wind pressure, which leads to relatively low wind capture efficiency.

[0005] 2. The installation method of wind capture equipment is relatively limited. It must be strictly perpendicular to the horizontal plane and the outer surface of the curtain wall. Therefore, it can only capture wind in one direction and lacks flexibility.

[0006] 3. The wind recovery system is entirely dependent on windy weather, and the flat and uniform design of the building's exterior surface makes it impossible to effectively utilize the wind shaft effect.

[0007] 4. Wind direction is easily affected by external factors and becomes dispersed, causing the wind force to gradually weaken during the diversion process, which further reduces the efficiency of wind power recovery. Summary of the Invention

[0008] The purpose of this invention is to provide a passive energy-saving building facade sine wave guide external envelope system, which solves the technical problems of existing technologies, such as low wind capture efficiency due to natural wind field turbulence, limited installation direction of capture equipment that can only capture a single wind direction, reliance on natural wind and inability to effectively utilize the wind shaft effect, and easy dispersion of wind direction.

[0009] This invention discloses a passive energy-saving building facade sine wave guide external envelope system, comprising:

[0010] The exterior facade assembly, installed on the outside of the floor slab, includes a sine wave guide mechanism and an exterior curtain wall arranged alternately from top to bottom. The sine wave guide mechanism has a wave-shaped ridge structure and an internal cavity.

[0011] The wind turbine generator is installed in the accommodating cavity;

[0012] The sine wave guiding mechanism has an air collection port at the trough of the upper surface and / or the peak of the lower surface, and an air vent is provided on the outer surface of the sine wave guiding mechanism.

[0013] This application can converge, guide, and discharge natural wind fields, thereby forming an effective vortex and converging the wind field at the air collection port. Under the same wind conditions, it can capture more wind energy resources, significantly improving the wind energy capture efficiency. It can also adapt to airflow in different directions, allowing wind turbine units to be installed concealed without affecting the building facade. It does not need to follow a fixed installation mode that is perpendicular to the horizontal direction, and can be flexibly arranged according to the actual wind direction at the installation location. Moreover, it enables the system to better adapt to complex and changing wind direction conditions, greatly improving the stability and reliability of wind energy utilization. Even in windless weather, the system can continuously generate a certain amount of airflow power to drive the wind turbine units, thereby effectively compensating for the problem of insufficient wind power and ensuring the continuity and stability of building energy supply.

[0014] Based on the above technical solution, the solution of this application can be further improved as follows:

[0015] Preferably, it further includes:

[0016] The interior curtain wall is arranged one-to-one between the floor slabs, and together with the exterior facade assembly and two adjacent floor slabs, it forms an inter-floor air duct, which is connected to the adjacent accommodating cavity.

[0017] The inner curtain wall has multiple fresh air inlets, and each fresh air inlet is equipped with an opening and closing plate for opening or closing the fresh air inlet. By adopting this solution, the fresh air inlets can be naturally concealed within the sine wave guide mechanism, without having any adverse effects on the building's shape, aesthetics, or ventilation effect, thus achieving a unity of function and aesthetics.

[0018] Preferably, the fresh air inlet is located in the upper part of the inner curtain wall and is concealed within the ceiling space; this solution satisfies functional requirements while maintaining the integrity of the interior interface and does not compromise the interior aesthetics.

[0019] Preferably, it further includes:

[0020] The secondary structure is located between the exterior facade assembly and the interior curtain wall. This design serves as a load-bearing connection, effectively transferring the wind load borne by the exterior facade assembly to the interior curtain wall and the main building structure, thereby enhancing the overall integrity and stability of the entire building structure.

[0021] Preferably, the sine wave guide mechanism is composed of several smoothly tapered sine waves connected end to end in sequence; this design facilitates the installation and arrangement of the sine wave guide mechanism and the wind turbine.

[0022] Preferably, the buckling smooth gradient includes:

[0023] Multiple grid supports are installed laterally at intervals on the outside of the floor slab;

[0024] Several buckling rays are installed on the outer edge of the grid support and arranged vertically at intervals;

[0025] Multiple shear wave panels are installed on the grid support, and buckling rays are provided between adjacent shear wave panels; this solution provides stable support, ensures overall stability, enhances structural strength, reduces overall weight, and facilitates construction and installation.

[0026] Preferably, the sine wave curved panel is divided into multiple reference sine wave guide plates by eight reference lines;

[0027] The eight reference lines are, in order: the outer contour line of the floor slab, the positioning line of the glass surface, the baseline of the glass vertical stiffener, the normal line of the aluminum plate vertical stiffener, the base line of the vertical stiffener, the vertical joint of the aluminum plate, the double line of the horizontal joint of the aluminum plate, and the baseline of the aluminum plate surface. This solution results in a relatively small size and light weight, making it easy to transport, install, and disassemble. Furthermore, during later maintenance, the problematic reference chord wave guide plates can be replaced individually, thereby reducing maintenance costs and workload.

[0028] Preferably, it further includes:

[0029] A rigid support is installed between the outer curtain wall and the floor slab; this solution enhances structural stability, improves wind resistance, and ensures flatness.

[0030] Preferably, the wind turbine is composed of multiple pairs of micro wind turbine rotors, which are installed on the vertical section of the grid support and form a multi-to-one combination with the air collection port. This solution avoids the need for an additional complex support system, reduces installation costs and difficulty, ensures the continuity of the overall power generation function of the wind turbine, and improves the reliability and stability of the system.

[0031] Preferably, the exterior curtain wall comprises:

[0032] Multiple curtain walls are erected vertically and arranged at horizontal intervals;

[0033] Multiple curtain wall panels are installed one-to-one between the curtain wall mullions. This solution disperses stress, improves the load-bearing capacity of the exterior curtain wall, reduces the workload and difficulty of on-site construction, increases construction speed and quality, and allows for easy disassembly and installation.

[0034] Through the above technical solution, the present invention achieves the following beneficial effects:

[0035] 1. This application relies on the wave-shaped ridge structure of the sine wave guide mechanism, which can gather, guide and discharge natural wind fields, thereby forming an effective vortex and converging the wind field at the air collection port. Under the same wind conditions, it can capture more wind energy resources and significantly improve the wind energy capture efficiency.

[0036] 2. This application utilizes a sine wave guide mechanism that can adapt to airflow in different directions and guide the airflow to the wind turbine. Therefore, the wind turbine can be installed in a concealed manner without affecting the building facade. It also does not need to follow a fixed installation mode that is perpendicular to the horizontal direction. It can be flexibly arranged according to the actual wind direction at the installation location, and enables the system to better adapt to complex and changing wind conditions, greatly improving the stability and reliability of wind energy utilization.

[0037] 3. In windless conditions, the uneven heat absorption of the sine wave guide mechanism and different parts of the external curtain wall under sunlight leads to local temperature field differences, which in turn generate rising airflow. The wave-like and windproof valley design on the outer surface further enhances the effect of this rising airflow. Therefore, even in windless weather, the system can continuously generate a certain amount of airflow power to drive the wind turbine, thereby effectively compensating for the problem of insufficient wind power and ensuring the continuity and stability of the building's energy supply.

Detailed Implementation

[0049] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0050] First, it should be noted that some directional terms used in the following description to clearly illustrate the technical solution of the present invention, such as the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," are all derived from the normal orientation of components in a passive energy-saving building facade sine wave guide outer envelope system. They are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0053] Example:

[0054] like Figure 1 As shown in the figure, this application discloses a passive energy-saving building facade sine wave guiding external envelope system. The system aims to effectively utilize large curtain walls or buckled facades, and through biomimetic design, naturally change the wind pressure impact angle of the building's outer contour, thereby forming a steady-state outdoor wind pressure. This can both reduce the feeling of strong winds at pedestrian height and increase the possibility of the facade bearing and capturing wind fields, thus realizing the effective utilization of wind energy and building energy conservation. Its specific structure includes: facade assembly 1 and wind turbine unit 2.

[0055] The facade assembly 1 is installed on the outside of the floor slab 7 and includes a sine wave guide mechanism 11 and an exterior curtain wall 12 arranged alternately from top to bottom. The sine wave guide mechanism 11 has a wave-shaped ridge structure and has an internal cavity 1101.

[0056] Specifically, the sine wave guide mechanism 11 adopts a biomimetic design, inspired by the Yardang landform. The unique terrain features of the Yardang landform can effectively guide and change the direction of airflow. By simulating these terrain features, the sine wave guide mechanism 11 guides and regulates the airflow around the building.

[0057] Among them, the sine wave guiding mechanism 11 has an air collection port 1102 at the trough of the upper surface and / or the peak of the lower surface, and an air vent 1103 is provided on the outer surface of the sine wave guiding mechanism 11.

[0058] The wind turbine 2 is installed in the cavity 1101 to convert wind energy into electrical energy, thereby providing partial power support for the building and achieving the purpose of energy conservation and emission reduction.

[0059] It should be noted that, as Figure 5 As shown, the sine wave guiding mechanism 11 is wave-shaped, so the concave areas of its upper and lower surfaces form a guiding groove structure, which plays a role in guiding and concentrating airflow. Then, by opening an air collection port 1102 in the center of this area, it can be ensured that wind energy is effectively utilized.

[0060] With the above-mentioned settings, this application achieves the following technical effects:

[0061] First, relying on the wave-shaped ridge structure of the sine wave guiding mechanism 11, the natural wind field can be gathered, guided and discharged, thus forming an effective vortex and converging the wind field at the air collection port 1102. Under the same wind conditions, more wind energy resources can be captured, significantly improving the wind energy capture efficiency.

[0062] Second, since the sine wave guide mechanism 11 can adapt to airflow in different directions and guide the airflow to the wind turbine 2, the wind turbine 2 can be installed in a hidden manner without affecting the building facade. It also does not need to follow the fixed installation mode that is perpendicular to the horizontal direction. It can be flexibly arranged according to the actual wind direction at the installation location, and the system can better adapt to complex and changing wind conditions, which greatly improves the stability and reliability of wind energy utilization.

[0063] Third, when there is no wind, the uneven absorption of heat by different parts of the sine wave guide mechanism 11 and the outer curtain wall 12 under sunlight leads to local temperature field differences, which in turn generates rising airflow. The wave-like and windproof valley design on the outer surface further enhances the effect of this rising airflow. Therefore, even in windless weather, the system can continuously generate a certain amount of airflow power to drive the wind turbine 2, thereby effectively compensating for the problem of insufficient wind power and ensuring the continuity and stability of the building's energy supply.

[0064] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, it also includes: an inner curtain wall 3, which is arranged one-to-one between the floor slabs 7, and together with the outer facade assembly 1 and the two adjacent floor slabs 7, it forms an inter-floor air duct 4. The inter-floor air duct 4 is connected to the adjacent accommodating cavity 1101, and each inter-floor air duct 4 is set in each floor and does not affect each other.

[0065] The inner curtain wall 3 has multiple fresh air inlets 31, and each fresh air inlet 31 is equipped with an opening and closing plate 32, which is used to open or close the fresh air inlet 31.

[0066] With the above settings, the fresh air inlet 31 can be naturally concealed within the sine wave guide mechanism 11, without having any adverse effects on the building's shape, aesthetics, or ventilation effect, thus achieving a unity of function and aesthetics.

[0067] Based on the above embodiments, such as Figure 4 As shown, the fresh air inlet 31 is located in the upper part of the inner curtain wall 3, which is used to hide it in the ceiling space, thus satisfying the functional requirements while maintaining the integrity of the interior interface and not damaging the interior aesthetics.

[0068] In some embodiments, such as Figure 1 As shown, it also includes a secondary structure 5, which is located between the exterior facade assembly 1 and the inner curtain wall 3. It serves as a load-bearing connection and can effectively transfer the wind load borne by the exterior facade assembly 1 to the inner curtain wall 3 and the main building structure, thereby enhancing the integrity and stability of the entire building structure.

[0069] In some embodiments, the sine wave guide mechanism 11 is composed of several buckled smooth gradient forms 111 connected end to end in sequence; it uses biomimetic crests, troughs, natural frequencies, and bidirectional amplitudes as basic elements to achieve orderly division of large-span facades, which not only helps to rationally guide the flow of air on the building facade and form good airflow organization, but also facilitates the installation and arrangement of the sine wave guide mechanism 11 and the wind turbine 2.

[0070] Based on the above embodiments, such as Figure 2 As shown, the buckling smooth gradient type 111 includes: multiple grid supports 1111, several buckling rays 1112, and multiple sine wave panels 1113, specifically configured as follows:

[0071] Multiple grid supports 1111 are installed laterally at intervals on the outside of the floor slab 7. As a basic support structure, they provide a stable installation platform for the subsequently installed buckled rays 1112 and chord wave panels 1113. The laterally spaced installation method can reduce the overall weight while ensuring structural strength and form a breathable wall structure, realizing the connection between the accommodating cavity 1101 and the inter-floor air duct 4. It can organize and guide the positive and negative airflow in an orderly manner and reduce the turbulent wind pressure phenomenon of rapid cooling and heating.

[0072] Several buckling rays 1112 are installed on the outer edge of the grid support 1111 and arranged vertically at intervals. The buckling rays 1112 are the outermost contour of the three-dimensional body of the facade, which plays a role in supporting the chord-shaped panel 1113, and enhances the structural strength and stability, and improves the load-bearing capacity of external wind force and other loads.

[0073] Multiple sine wave curved panels 1113 are installed on the grid support 1111, and buckling rays 1112 are provided between adjacent sine wave curved panels 1113, which helps to guide air to flow along a specific path and realize functions such as air collection and flow guidance.

[0074] The structural design of the buckling smooth gradient variant 111 described above provides stable support, ensures overall stability, enhances structural strength, reduces overall weight, and facilitates construction and installation.

[0075] Based on the above embodiments, such as Figure 2 As shown, the sine wave curved panel 1113 is divided into multiple reference sine wave guide plates 11131 by eight reference lines. The eight reference lines are, in order: the outer contour line of the floor slab, the positioning line of the glass surface, the baseline of the glass vertical stiffener, the normal line of the aluminum plate vertical stiffener, the vertical stiffener base line, the vertical joint of the aluminum plate, the double line of the horizontal joint of the aluminum plate, and the baseline of the aluminum plate surface.

[0076] By dividing the sine wave curved panel 1113 into multiple reference sine wave guide plates 11131, its size can be relatively small and its weight lighter, thus facilitating transportation, installation and disassembly; and in later maintenance, the reference sine wave guide plate 11131 with problems can be replaced individually, thereby reducing maintenance costs and workload.

[0077] In some embodiments, such as Figure 1 and Figure 3 As shown, it also includes: a layered rigid support 6, which is disposed between the outer curtain wall 12 and the floor slab 7, and has the following effects:

[0078] 1. Enhance structural stability: It can effectively transfer the load on the curtain wall 12 to the floor slab 7, and then distribute it to the entire building structure, so as to avoid the curtain wall 12 from deforming or being damaged due to excessive local stress, and enhance the stability of the entire building structure.

[0079] II. Improve wind resistance: Provide additional lateral support for the exterior curtain wall 12, reduce the swaying and displacement of the exterior curtain wall 12 under wind load, and improve the wind resistance of the building;

[0080] Third, ensure flatness: It can limit the deformation of the outer curtain wall 12, ensure that the outer curtain wall 12 remains flat during long-term use, avoid unevenness, twisting and other phenomena, and maintain the aesthetics of the building's appearance.

[0081] In some embodiments, the wind turbine 2 is composed of multiple pairs of micro wind turbines, which are installed on the vertical section of the grid support 1111 and form a multiple-to-one combination with the air collection port 1102.

[0082] It should be noted that the grid support 1111 has an "F" shaped structure, including a vertical section and a horizontal section; one side of the vertical section is connected to the floor slab 7, and the other side is provided with a horizontal section; therefore, by installing the micro wind turbine in the vertical section, stable support can be provided for the turbine, thereby avoiding the need to add an extra complex support system and reducing installation costs and difficulties.

[0083] By combining multiple turbines into one, the risks in the wind energy utilization process can be dispersed. This avoids the situation where one or more pairs of turbines fail or are unable to work normally due to external factors such as obstruction by debris or damage from strong winds. In such cases, other turbines can still continue to operate, ensuring the continuity of the overall power generation function of the wind turbine unit 2 and improving the reliability and stability of the system.

[0084] In some embodiments, such as Figure 1 As shown, the exterior curtain wall 12 includes: multiple curtain wall mullions 121 and multiple curtain wall panels 122; wherein, the multiple curtain wall mullions 121 are vertically arranged and horizontally spaced apart; the multiple curtain wall panels 122 are arranged one-to-one between the curtain wall mullions 121.

[0085] Preferably, such as Figure 4 As shown, the top and / or bottom of the vertical section of the buckling smooth gradient variant 111 has a horizontal section for abutting against the curtain wall mullion 121, thereby increasing the contact area, improving the connection strength, and allowing the air collection port 1102 to be concealed, thus improving the aesthetics.

[0086] First, the curtain wall mullions 121 and the curtain wall panels 122 work together to form a complete frame structure, which has good integrity and rigidity, and can effectively transfer external loads to the main building structure, thereby dispersing stress and improving the load-bearing capacity of the exterior curtain wall 12.

[0087] Secondly, the curtain wall mullions 121 can be prefabricated and installed to form a basic frame structure, and then the curtain wall panels 122 can be installed one by one between the mullions. This modular construction method can reduce the workload and difficulty of on-site construction and improve the construction speed and quality.

[0088] Finally, since the curtain wall panel 122 is independently installed, if a panel is damaged or needs to be replaced, it can be easily disassembled and installed without affecting the normal use of other parts.

[0089] Further explanation is provided regarding this application:

[0090] During normal operation, due to the wind pressure difference between the outside of the air collecting port 1102 and the outside of the air vent 1103, the airflow will enter the accommodating cavity 1101 through the air collecting port 1102 and then flow out of the accommodating cavity 1101 through the air vent 1103, thereby forming an airflow with a certain velocity and pressure, which drives the wind turbine 2 to operate and generate electricity, converting wind energy into electrical energy.

[0091] When indoor air quality is poor, such as Figure 4 As shown, when the opening and closing plate 32 is opened and the fresh air inlet 31 is opened, due to the wind pressure difference between the indoor area and the air collection port 1102, the outdoor airflow can enter the indoor area through the air collection port 1102, the accommodating cavity 1101, the inter-floor air duct 4 and the fresh air inlet 31 in sequence; or, the fresh air system can be turned on to draw in the indoor air, so that the indoor airflow forms a negative pressure circulation, thereby improving the indoor airflow. Then the indoor air is output to the outside through the fresh air inlet 31, the inter-floor air duct 4, the accommodating cavity 1101 and the vent 1103 in sequence.

[0092] The installation process for this application is as follows:

[0093] 1. Install grid support 1111 on the outside of floor slab 7. The structure of grid support 1111 is confirmed by the cross-sectional dimensions of the building model at that location, and reserve secondary structure 5 within the height of the outer curtain wall 12.

[0094] 2. Connect the treated buckling rays 1112 to the outermost side of the grid support 1111, and fix several buckling rays 1112 to the corresponding horizontal ends of the grid support 1111 in sequence.

[0095] Third, based on the baseline, multiple reference sine wave guide plates 11131 are sequentially divided, and fixed on the buckling ray 1112 with four points coplanar. The reference sine wave guide plates 11131 enclose a sine wave guide mechanism 11 with a wave-shaped ridge structure.

[0096] 4. Install wind turbine 2 on one side of each floor slab 7, and fix the micro wind turbine to the vertical section of the grid support 1111, and make it in the same plane as the buckling ray 1112 on the side of the air collection port 1102.

[0097] 5. Install the exterior curtain wall 12 on each floor, using the floor slab 7 as support, and install it in sections to complete the overall enclosure of the exterior curtain wall 12 and the chord wave guide mechanism 11;

[0098] 6. Ensure the width of the inter-floor air duct 4 before installing the inner curtain wall 3, and check the position of the fresh air inlet 31 at the top to ensure that it can be used normally.
