DETAILED DESCRIPTION

[0032] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined object of the application, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0033] Please refer to Figures 1-6 The embodiment provides a low-energy-consumption curtain wall external sunshade system 3, which comprises a curtain wall module 1, an adapter module 2 and a sunshade module 3, the curtain wall module 1 is provided with a cavity, one end of the adapter module 2 is located in the cavity and connected with the curtain wall module 1, and the other end is connected with the sunshade module 3.

[0034] The adapter module 2 comprises a first adapter unit 21 and a second adapter unit 22, the sunshade module 3 is connected with the curtain wall module 1 through the first adapter unit 21 and the second adapter unit 22, both the adapter units comprise an adapter 211, an adapter back plate 212, an adapter anchor plate 213 and an adapter bolt set 214, the adapter 211 is integrally connected with the adapter anchor plate 213 through perpendicular welding, the adapter back plate 212 is located in the curtain wall module 1, the adapter anchor plate 213 is located outside the cavity, the adapter back plate 212 is connected with the adapter anchor plate 213 through the adapter bolt set 214, and the adapter anchor plate 213 and the adapter back plate 212 clamp one side wall of the curtain wall module 1, and the sunshade module 3 is connected with the adapter 211.

[0035] The existing curtain wall external sunshade module 3 has various functions and forms, can use materials including glass, metal plate, stone plate and the like, and has increasingly rich and diversified appearance design, and can meet different lighting and sunshade requirements of buildings. However, the common connection modes of the curtain wall external sunshade module 3 at present are as follows.

[0036] Suspension connection mode: the sunshade module 3 is fixed by being suspended on an aluminum alloy keel outside the curtain wall, and is mainly used for sunshade of a small area of the curtain wall. The disadvantage is that installation and maintenance are inconvenient, the aluminum alloy keel is insufficient in strength and is not firmly fixed, and the phenomenon of fluttering is prone to occur.

[0037] Direct bonding connection: The sunshade panel is directly bonded to the curtain wall panel, secured using various direct fixing methods. The disadvantages are that it requires adhesive, which can lead to problems such as adhesive aging, cracking, and detachment. It also doesn't adequately consider the building's thermal insulation. Furthermore, once installed, this bonding method is difficult to modify or repair.

[0038] Cantilever connection type: also known as "Y-shaped clamp connection," this type of connection between the sunshade and the curtain wall panels typically uses a special aluminum alloy bracket and adhesive, employing a Y-shaped clamp connection for a high degree of stability. The disadvantage is that this connection method is prone to vibration under wind force, which can affect the exterior surface appearance of the curtain wall.

[0039] The shading module 3, connected to the curtain wall module 1 via the adapter module 2, effectively blocks the sun's heat and ultraviolet radiation, thus providing shading in summer, reducing indoor temperature and air conditioning load, and consequently reducing building energy consumption. Furthermore, the angle of the shading module 3 can be adjusted during the design phase to meet different shading needs. The shading module 3 uses a first adapter unit 21 and a second adapter unit 22 for connection, improving the stability of the external curtain wall shading module 3. It boasts high strength, can withstand high wind pressure, its own weight, and earthquakes, and provides better lighting and ventilation for the building, achieving shading without compromising its aesthetics. The connection method is highly efficient: integrated with the curtain wall module 1, the connection method is more advanced and complete, easy to install and maintain, and has low maintenance costs: due to the use of low-energy materials and efficient connection methods, the external curtain wall shading module 3 has lower maintenance costs.

[0040] To better connect the sunshade module 3 to the curtain wall module 1, in one embodiment, the second adapter unit 22 has the same components as the first adapter unit 21. The adapter 211 of the second adapter unit 22 is slightly longer than the adapter 211 of the first adapter unit 21 depending on the installation method. This allows the sunshade module 3 to maintain a downward tilt, thereby achieving the sunshade effect while ensuring the stability and connection strength of the sunshade module 3.

[0041] In order to better install the curtain wall module 1, in an embodiment, the curtain wall module 1 comprises a plurality of vertically installed curtain wall main girders 11, a plurality of transversely installed curtain wall secondary girders 12, a plurality of curtain wall glass plates 13, the curtain wall secondary girders 12 are welded to the curtain wall main girders 11, the plurality of curtain wall glass plates 13 are installed in the frame formed by the connection of the curtain wall secondary girders 12 and the curtain wall main girders 11, and the plurality of curtain wall main girders 11 are self-locked to the building structure embedded parts. The curtain wall main girders 11 are connected to the secondary girders by welding, which is generally more secure than bolt connection, can effectively enhance the stability and load-bearing capacity of the curtain wall module 1, and at the same time, the curtain wall main girders 11 are connected to the building structure embedded parts by self-locking connection, which can effectively avoid or reduce the influence of external forces on the curtain wall module 1, and improve the safety of the curtain wall module 1. Moreover, through the cross-welding connection method, the construction and disassembly process of the curtain wall module 1 can be more simple and convenient, reducing the waste of time and labor cost. This connection method can adapt to curtain wall plates of various materials, is not limited by the fixing method and size of the glass plate, has strong applicability, does not use screws and bolts and other connecting parts, makes the curtain wall surface more flat and beautiful, and meets the aesthetic needs of architectural design.

[0042] In order to better connect the adapter module 2 with the curtain wall module 1, in an embodiment, a recess 111 is formed on one side wall surface of the curtain wall main girder 11, a boss 112 is arranged on the inner wall of the recess 111 opposite the two side walls, the adapter back plate 212 is placed vertically to the curtain wall main girder 11 and located in the recess 111 and on one side of the inner bottom surface of the boss 112 close to the recess 111, and the adapter back plate 212 is fixed in the recess 111 of the curtain wall main girder 11 by clamping the boss 112 with the adapter bolt set 214. By forming the recess 111 on one side wall surface, arranging the boss 112 in the recess 111, and installing the adapter back plate 212 therein, better dispersion of the load on the curtain wall surface and better fusion are achieved. Through the design of the recess 111, a better fixing position and more stable support can be provided for the adapter module 2. Since the adapter back plate 212 is placed vertically to the curtain wall main girder 11 and located in the recess 111, the adapter module 2 has better spatial adaptability and better stability under various conditions, thereby improving the overall flatness and stability of the curtain wall. In addition, this design makes the adapter back plate 212 better fused with the curtain wall main girder 11, without affecting the aesthetic and overall appearance design of the curtain wall. Finally, this connection method is easy to install and maintain, and can be improved flexibly according to different requirements, providing the curtain wall module 1 of the building with more efficient, beautiful, stable, safe and easy-to-maintain effects.

[0043] In order to improve the waterproof, windproof and other effects of the curtain wall module 1, in an embodiment, the sealing glue is arranged at the connection between the curtain wall glass plate 13 and the curtain wall main rail 11 and the secondary rail. The sealing glue can play the role of waterproof, leakage prevention, windproof, dustproof and the like in the building, which can effectively prevent water and air from entering the building interior, and maintain the indoor comfort and hygiene. Secondly, the sealing glue layer between the glass and the rail can also play the role of anti-seismic, windproof and preventing the glass plate from breaking, thereby enhancing the stability and durability of the curtain wall. In addition, the nature of the sealing glue can also make the full size of the connection be in a pressure state, and can withstand deformation and displacement, which can better adapt to the change of temperature range, and also can absorb the differential deformation between the glass plate and the secondary rail and the curtain wall main rail 11, thereby relieving the impact force between the rails and ensuring the stability and endurance of the curtain wall. Secondly, the design of the sealing glue can effectively reduce the release of harmful substances such as electric leakage and electromagnetic waves, thereby improving the safety and environmental protection of the building.

[0044] In order to better connect with the adapter module 2, in an embodiment, the sunshade module 3 includes an aluminum plate unit 31 and a connecting unit 32, the aluminum plate unit 31 is connected with the adapter module 2 through the connecting unit 32, and the aluminum plate unit 31 provides sunshade for the curtain wall module 1. The aluminum plate unit 31 has good sunshade performance, can effectively block sunlight, reduce the temperature inside the building, reduce the air conditioning load, thereby reducing energy consumption and achieving energy-saving effect. At the same time, the aluminum plate unit 31 is a recyclable material, which can be recycled after use and has no harm to the environment. In addition, the aluminum plate unit 31 has excellent properties such as waterproof and corrosion resistance, and can maintain a long service life, thereby reducing the cost of replacement and maintenance. The aluminum plate unit 31 is connected with the adapter module 2 through the connecting unit 32, which not only provides sunshade effect, but also has good bending strength, good wind pressure performance, is convenient to clean, can effectively prevent ultraviolet rays from penetrating, reduces solar radiation, can be recycled and regenerated, and is environmentally friendly and energy-saving.

[0045] In order to better connect the adapter 211 and the aluminum plate unit 31, in an embodiment, the connecting unit 32 includes a first connecting piece 321 and a second connecting piece 322, one end of the first connecting piece 321 and the second connecting piece 322 is connected with the adapter 211 through a bolt, and the other end is connected with the aluminum plate unit 31. The aluminum plate unit 31 and the adapter 211 are connected through the first connecting piece 321 and the second connecting piece 322. Since the connecting unit 32 is connected by bolts, the structure is more solid and firm, which can provide higher strength guarantee. In addition, the bolt connection can facilitate the replacement, disassembly or maintenance of individual components without affecting the operation of the whole system. Since the bolt connection of the connecting unit 32 usually uses lightweight metal materials, the overall unit is light and easy to carry and layout. At the same time, the bolt connection can be quickly installed, thereby improving the assembly efficiency and reducing the assembly time.

[0046] In order to better play the sunshade effect, in an embodiment, the aluminum plate unit 31 comprises a punched aluminum plate 311 and a sealing plate 312, the shape of the punched aluminum plate 311 is in the shape of a U-shaped, the sealing plate 312 is connected to both ends of the punched aluminum plate 311, the punched aluminum plate 311 is connected with the first connecting piece 321 through the back countersunk head bolt set, and the punched aluminum plate 311 is connected with the sealing plate 312 through the side countersunk head bolt. Since the aluminum plate material itself has the characteristics of light weight, the weight of the whole unit can be effectively reduced, thereby reducing the burden of the structure. Moreover, the aluminum plate is not easy to corrode and rust, and can provide a longer service life. At the same time, the sealing plate 312 and the punched aluminum plate 311 are connected through the side countersunk head bolt, this connection mode can provide higher strength and reliability, so that the bent punched aluminum plate 311 can maintain its stability, to ensure better sunshade effect.

[0047] Based on the above low-energy consumption curtain wall external sunshade module 3, the application also provides a low-energy consumption curtain wall external sunshade installation method, and the specific method steps are as follows:

[0048] S1: Determine the installation position, elevation, inclination angle and number of the curtain wall module 1, the sunshade module 3 and the adapter module 2.

[0049] For the determination of the installation position, elevation, inclination angle and number of the sunshade module 3 and the adapter module 2 in the curtain wall module 1, the following steps need to be followed:

[0050] Based on the design drawings and specification requirements, the installation position and number of the sunshade module 3 and the adapter module 2 are determined. The sunshade module should be located on the main facade to reduce the influence of solar radiation and direct light entering the building, thereby improving the indoor temperature comfort. The adapter module 2 is used to connect the sunshade module 3 and the curtain wall module 1 to ensure its stability and reach a higher network.

[0051] When designing a sunshade module 3, the geographical location, solar directness and altitude of the region should be considered, and a reasonable inclination angle is set for the sunshade system.

[0052] After confirming the installation position, detailed measurement and elevation of the curtain wall module 1 and the sunshade module 3 need to be carried out to ensure that the installation position and height are accurate and correct.

[0053] The following factors need to be considered when determining the inclination angle:

[0054] Reduce the influence of solar radiation on the interior of the building: when the sun is directly on the ground, the smaller the incidence angle, the smaller the influence of solar radiation on the interior of the building. Therefore, according to the location and direction of the building, a suitable inclination angle is determined to ensure that the influence of solar radiation on the interior of the building can be reduced at the hottest time.

[0055] Aesthetic and design requirements: The tilt angle also needs to consider the design intent of the architect. The architect may need to create a specific appearance effect or consider other aesthetic goals, such as maintaining the purity of the building or drawing decorative patterns on the windows. In this case, the impact of the tilt angle on these goals needs to be considered.

[0056] Structural stability: The shading system of the building needs to maintain its stability and safety. If the selected tilt angle is too large or too small, it may have an adverse effect on the structure. Therefore, not only the position of the shading system in the plane and space needs to be considered, but also the force it needs to withstand and other factors, to ensure that the selection of the tilt angle will not threaten its stability and safety.

[0057] Energy-saving requirements: The tilt angle may also need to be considered for the energy-saving requirements of the building. By choosing the right tilt angle, the operation of the air conditioner inside the building can be reduced within the business scope of the shading system, and energy-saving benefits can be improved.

[0058] Elevation refers to the height of the shading module 3 or the adapter module 2 relative to the ground, which generally needs to consider the following factors to determine:

[0059] Line of sight factor: The elevation needs to consider the height of human vision to ensure that the system can better shade or connect the curtain wall system and not block people's view. Architects can consider line-of-sight sensors, average human height, and line-of-sight angles to determine the elevation.

[0060] Appearance requirements: The elevation also needs to be consistent with the overall style of the building's appearance. If the building is themed with modernity, high technology, or other futurism, the elevation should also be adjusted to better support the overall appearance.

[0061] Wind load factor: Buildings installed in high-wind areas will be affected by large wind loads, so the design wind load needs to be calculated according to the parameters of the building to determine the installation height of the shading system to ensure that the system has sufficient strength and stability.

[0062] Sunlight time and direction: The elevation also needs to consider the time and direction of the sun to ensure that the shadow cast by the system can accurately cover the area that needs to be shaded and improve indoor temperature comfort.

[0063] By deepening the design of the above factors, the curtain wall keel installation position, shading module 3 and adapter module 2 installation position, elevation, tilt angle, and quantity are determined.

[0064] S2: Install the main keel and secondary keel of the building curtain wall module 1;

[0065] S3: placing the adapter back plate 212 on one side of the boss 112 close to the inner bottom surface of the groove 111, and installing the adapter anchor plate 213 on the other side of the boss 112 through the adapter bolt set 214, and clamping the boss 112 with the adapter back plate 212 and the adapter anchor plate 213;

[0066] S4: installing the sunshade module 3 one by one, and adjusting and correcting the position and elevation thereof.

[0067] In step S3, the cavity in the curtain wall module 1 during installation of the adapter module 2 is set according to the deepening design requirement, so as to ensure that the adapter module 2 has better spatial adaptability and better stability under various conditions, thereby improving the overall flatness and stability of the curtain wall.

[0068] In step S4, the installation angle of the sunshade module 3 is determined according to the sunshine analysis, and the adjacent sunshade modules 3 are arranged on the same adapter module 2, which can maintain a longer service life and reduce the cost of replacement and maintenance.

[0069] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the present application.
