[0024] The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0025] It has to be noted that, when referring to a component being "connected" to another component, it can be directly connected to the other component or an intervening component can be present. When referring to a component being "disposed on" another component, it can be directly disposed on the other component or an intervening component can be present. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar terms as used herein are used for the purpose of description only.

[0026] Some embodiments of the present application will be described in detail with reference to the drawings, in which the following embodiments and features are not mutually exclusive and can be combined with each other.

[0027] Referring to Figure 1 The embodiments of the present application provide a lightning protection curtain wall 100, which comprises a first wire 10, a metal frame 20 connected with the first wire 10, and a lightning protection node 30 connected with the metal frame 20. The lightning protection node 30 comprises a channel steel 31 disposed in a building, a voltage equalizing ring 32 connected with the channel steel 31, and a second wire 33 having one end connected with the metal frame 20 and the other end connected with the voltage equalizing ring 32. The channel steel 31 has one end connected with a lightning protection device (not shown in the figure) and the other end connected with a grounding device 40. The grounding device 40 is located underground, and the lightning protection device is located on the top of the building. The voltage equalizing ring 32 is composed of building reinforcement, and a plurality of voltage equalizing rings 32 are arranged around the periphery of the building and along the height of the building.

[0028] The first wire 10 is connected with the metal frame 20, forming an electrical connection channel between the curtain wall and the external lightning protection system. The first wire 10 is generally a galvanized steel wire, which has the advantages of strong conductivity and corrosion resistance, and can maintain a low resistance value during long-term use, avoiding the problem of poor current conduction caused by poor grounding or material degradation.

[0029] The connection between the first wire 10 and the metal frame 20 is achieved through T-shaped welding, which can ensure stable electrical contact between the first wire 10 and the metal frame 20, avoiding the common phenomenon of looseness or poor contact in traditional connection methods. In addition, the welding length of the first wire 10 is set to at least 75 mm, which ensures the current conduction capacity of the connection, minimizes the resistance when lightning current passes through the wire, and further improves the overall conductivity of the lightning protection system.

[0030] The first wire 10 is coated with a layer of red lead 331. The first wire 10 is coated with a layer of red lead 331. Mainly for the first wire 10 corrosion protection and enhance its durability, specifically, the red lead layer 331 is a common anti-corrosion coating. Although the red lead layer 331 is mainly anti-corrosion coating, it can also improve the surface smoothness of the first wire 10 to some extent, reduce the surface resistance caused by external pollutants or oxidation layer, improve the conduction efficiency when lightning current passes through. Especially when lightning occurs, the dispersion of current or excessive resistance is reduced, ensuring that the lightning current can quickly and stably pass through the conductive wire to the grounding system.

[0031] The first wire 10 not only effectively guides the lightning current into the grounding device 40, but also forms an effective potential balance with the grounding device 40 through the channel steel 31, so that the lightning current is more evenly distributed, reducing the risk of local overload. This design significantly improves the lightning resistance of the building in practical application, avoiding serious damage to the structure and internal facilities of the building caused by lightning.

[0032] The equalizing ring 32 and the channel steel 31 constitute the key part of the lightning protection node 30. The equalizing ring 32 is composed of building reinforcement and surrounds the building periphery along the building height. These equalizing rings 32 not only provide an effective distribution path for lightning current, but also reduce the phenomenon of excessive local current density by uniformly distributing current when lightning strikes.

[0033] The connection between the equalizing ring 32 and the channel steel 31 is realized through the second wire 33. One end of the second wire 33 is connected to the channel steel 31, and the other end is connected to the equalizing ring 32, so that the lightning current can be dispersed from the lightning protection device through the equalizing ring 32 to other parts of the building, and finally connected to the first wire 10, and the first wire 10 is connected to the grounding device 40, and then guided into the ground through the grounding device 40. The second wire 33 is generally a flat aluminum plate bent into a shape. This material has high conductivity and can maintain stable current conduction capacity for a long time.

[0034] The equalizing ring 32 is arranged along the building height, and the distance between adjacent equalizing rings 32 is S (satisfying S≤10m), which means that an effective current distribution channel can be formed in different height regions of the lightning protection curtain wall 100, ensuring that the lightning current can flow uniformly along the surface of the building. This structural design not only improves the conduction efficiency of lightning current, but also maintains high safety and stability under multiple lightning strikes.

[0035] The distance between two adjacent equalizing rings 32 along the perimeter of the building is set as A, and satisfies the relationship: S≤6m. This feature is an optimized design for the rationality of the equalizing ring 32 arrangement in the lightning protection curtain wall 100 system, ensuring the maximum effect of the lightning protection device, especially in handling the lightning current distribution, which can reduce the potential danger caused by the concentration of lightning current.

[0036] The connection between the lightning protection device and the grounding device 40 is crucial in the lightning protection curtain wall 100 system. In this embodiment, one end of the channel steel 31 is connected to the lightning protection device, and the other end is connected to the grounding device 40. The lightning protection device is located at the top of the building, which can effectively guide the lightning current into the system, while the grounding device 40 is located underground, ensuring that the lightning current can be safely released to the ground.

[0037] This design ensures that the lightning current can smoothly flow from the top of the building to the grounding device 40 without causing damage to the building interior and structure through a reasonable connection layout. The effective connection between the lightning protection device and the grounding device 40 not only improves the efficiency of lightning current conduction, but also, with the help of multiple lightning protection nodes 30, makes the lightning current evenly distributed and effectively reduces the risk of local current overload.

[0038] Through the above structure and connection method, the embodiment solves the problems of low conduction efficiency and uneven distribution of lightning current in the prior art. When applied in high-rise buildings, this design can effectively avoid damage to the building structure caused by lightning, improve the lightning resistance of the building, and thus ensure the safety of the building and its internal facilities.

[0039] Through the above structure and design, the lightning protection curtain wall 100 can provide more reliable lightning protection in high-rise buildings. The design and arrangement of each lightning protection node 30 ensure that the lightning current can be effectively dispersed through multiple paths, avoiding local damage caused by current concentration. In addition, the optimization of the connection method improves the conduction efficiency and reduces the grounding resistance, thereby effectively improving the overall performance of the lightning protection system.

[0040] In practical applications, the lightning protection curtain wall 100 can be widely used in various high-rise buildings, commercial buildings, residential buildings, etc., especially in areas with frequent lightning activity, which can provide strong lightning protection and ensure the safety of the building and its occupants.

[0041] The above is only an embodiment of the present application, and it should be noted that those skilled in the art can make improvements without departing from the inventive concept, but these are within the scope of protection of the present application.
