Description

Technical Field

[0001] This application relates to the field of curtain wall technology, and in particular to a curtain wall with lightning protection structure and its construction method. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building, hung like a curtain, hence also called a "curtain wall." It is a lightweight wall structure commonly used in modern large and high-rise buildings for decorative purposes. A curtain wall consists of panels and a supporting structural system, allowing for a certain degree of displacement relative to the main structure or deformation. When the building height exceeds 60 meters, the curtain wall is susceptible to lightning strikes, therefore lightning protection measures are required.

[0003] Currently, patent document CN214673015U discloses a curtain wall lightning protection structure, including a building body and several curtain wall units. Each curtain wall unit includes vertical joists installed between the building body and the curtain wall. Down conductors are installed inside the building body, and a grounding device is installed at the bottom of the building body. Several equipotential rings are installed on the outer wall of the building body, each equipotential ring being electrically connected to the down conductor of the building body. Connectors are fixedly installed between the equipotential rings and the vertical joists. The equipotential rings closest to the ground are electrically connected to the grounding device. When lightning strikes a curtain wall unit, part of the current moves from the vertical joists to the grounding device of the building body; another part of the current moves through the connectors and equipotential rings to the down conductor of the building body. The equipotential rings conduct the current through different vertical joists at the same horizontal height, making the voltage between different vertical joists at the same horizontal height the same, effectively improving the curtain wall's protection against side-strike lightning.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During thunderstorms, rainwater adheres to the glass. Because rainwater is conductive, it has a certain attraction to lightning charges, causing lightning to directly strike the glass and easily leading to glass damage. Summary of the Invention

[0005] To reduce the possibility of glass damage, this application provides a curtain wall with a lightning protection structure and its construction method.

[0006] Firstly, this application provides a curtain wall with a lightning protection structure, which adopts the following technical solution:

[0007] A curtain wall with a lightning protection structure includes a curtain wall unit. Each curtain wall unit includes horizontal and vertical keels fixedly mounted on the main building structure, forming a rectangular frame. The curtain wall unit also includes glass installed within the rectangular frame. A winding shaft is rotatably mounted within each vertical keel, located on the side of the glass facing away from the main building structure. The length direction and rotation axis of the winding shaft are parallel to the length direction of the vertical keel. A metal mesh is wound onto the winding shaft. A first conductive rod is fixedly mounted at the free end of the metal mesh, with its length direction parallel to the length direction of the winding shaft. The first conductive rod is slidably mounted on the horizontal keel, with its sliding direction parallel to the length direction of the horizontal keel. The curtain wall also includes a first driving component for driving the first conductive rod to slide and for laying the metal mesh on the glass.

[0008] By adopting the above technical solution, in the event of thunderstorms, the first driving component drives the first conductive rod to slide, which in turn moves the metal mesh. The metal mesh is unwound from the winding shaft. After the first conductive rod slides to the opposite vertical keel, the metal mesh is laid flat on the glass. When rainwater on the glass attracts electrical charges, the charges move to the metal mesh and towards it. Once on the metal mesh, the charges move along the mesh's arrangement, towards the first conductive rod and the winding shaft, and then onto the vertical keel. The charges are then transferred along the vertical keel to the main building structure and down the building's lower guide wire to the ground. This process reduces the likelihood of charges hitting the glass, thus reducing the possibility of shattering it. Simultaneously, the metal mesh, under the action of the winding shaft, maintains a certain distance from the glass, ensuring that when charges move towards the glass, they first pass through the metal mesh. As the charges pass through the metal mesh, they are transferred to the ground via the vertical keel, further improving the safety of the glass. The mesh structure allows light to pass through the mesh openings and enter the room, ensuring indoor brightness.

[0009] Optionally, a metal rod is fixedly provided on the side of the first conductive rod away from the take-up shaft. The length direction of the metal rod is perpendicular to the length direction of the first conductive rod. A insertion groove for inserting the metal rod is provided on the vertical keel away from the take-up shaft. The inner diameter of the insertion groove is equal to the inner diameter of the metal rod.

[0010] By adopting the above technical solution, when the first conductive rod moves toward the opposite vertical keel, the first conductive rod drives the metal rod to move toward the vertical keel. The metal rod is inserted into the insertion slot, so that the first conductive rod is connected to the vertical keel, so that the charge on the metal mesh can move to the vertical keel, and thus facilitate the transfer of charge to the ground. The inner diameter of the metal rod is equal to the inner diameter of the insertion slot, which improves the connection stability between the metal rod and the vertical keel, thereby ensuring the connection stability between the first conductive rod and the vertical keel, and facilitating the transfer of charge on the metal mesh to the vertical keel.

[0011] Optionally, the first driving component includes a first motor disposed within the vertical keel, a lead screw coaxially disposed on the output shaft of the first motor, the length direction of the lead screw being parallel to the length direction of the transverse keel, the end of the lead screw facing away from the first motor being rotatably disposed on the opposite vertical keel, and the first conductive rod being threadedly connected to the lead screw.

[0012] By adopting the above technical solution, the first motor is started, the first motor drives the lead screw to rotate, the rotation of the lead screw causes the first conductive rod to slide, and the first conductive rod causes the metal mesh to be laid on the glass, which is simple and convenient to operate; at the same time, it is easy to fix the metal mesh to the above-mentioned protective state.

[0013] Optionally, a mounting box is provided inside the vertical keel, the first motor is located inside the mounting box, the mounting box has a through hole for the output shaft of the first motor to move out, and insulating sleeves are fixedly provided on both the inner and outer walls of the mounting box; an insulating coupling is provided on the output shaft of the first motor, and the lead screw is coaxially connected to the insulating coupling.

[0014] By adopting the above technical solutions, the waterproof performance of the first motor is improved and its service life is extended under the action of the mounting box. The vertical keel, as the main pathway for charge transfer, is prone to damage when charge is transferred to the first motor. The insulating sleeve isolates the charge transfer path, reducing the possibility of charge reaching the first motor and thus reducing the likelihood of damage. When charge on the metal mesh is transferred to the first conductive rod, the first conductive rod transfers the charge to the lead screw, which in turn transfers the charge to the first motor. The insulating coupling isolates the charge transfer path on the lead screw, further reducing the possibility of damage to the first motor.

[0015] Optionally, a lightning rod is rotatably mounted on the vertical keel, the length direction of the lightning rod is parallel to the length direction of the vertical keel, the rotation axis of the lightning rod is perpendicular to the length direction of the vertical keel, and a second driving component for driving the lightning rod to rotate is provided on the vertical keel.

[0016] By adopting the above technical solution, during thunderstorms, the lightning rod is driven to rotate by the second driving component. The lightning rod rotates in the direction away from the vertical keel. After the lightning rod rotates to the tilted state, the end of the lightning rod is located on the side of the metal mesh away from the main building, so that the charge moves towards the metal mesh. The charge first passes through the lightning rod. In the above process, the charge moving to the metal mesh and glass is reduced, further reducing the possibility of glass damage. The charge on the lightning rod is transferred to the vertical keel through the lightning rod and then to the ground.

[0017] Optionally, the second driving component includes a driving rod rotatably disposed within the vertical keel, with a first bevel gear disposed at each end of the driving rod; the first motor is a dual-axis motor, and a second bevel gear meshing with the first bevel gear is disposed on the output shaft of the first motor away from the lead screw; a hinge shaft is rotatably disposed on the vertical keel, the lightning rod is disposed on the hinge shaft, and a third bevel gear meshing with the first bevel gear is sleeved on the hinge shaft.

[0018] By adopting the above technical solution, when the first motor drives the lead screw to rotate, the first motor drives the second bevel gear to rotate, the second bevel gear rotates and drives the first bevel gear to rotate, the first bevel gear rotates and drives the drive rod to rotate, the drive rod rotates and drives the first bevel gear on the other side to rotate, the first bevel gear drives the third bevel gear to rotate, the third bevel gear rotates and drives the hinge shaft to rotate, thereby driving the lightning rod to rotate. The operation is simple and convenient.

[0019] Optionally, the lightning rod includes a connecting rod mounted on a hinge shaft and a second conductive rod rotatably mounted on the connecting rod. The rotation axis of the second conductive rod is perpendicular to the length direction of the hinge shaft. A connecting rope is wound on the hinge shaft, and the free end of the connecting rope is fixedly mounted on the second conductive rod. When the hinge shaft drives the connecting rod to rotate away from the vertical keel, the hinge shaft winds up the connecting rope, causing the second conductive rod to rotate towards the glass.

[0020] By adopting the above technical solution, when the hinge shaft rotates and drives the connecting rod to rotate, the hinge shaft winds up the connecting rope, and the winding of the connecting rope drives the second conductive rod to rotate, so that the second conductive rod is located in front of the glass. When the charge is transferred to the second conductive rod, the charge is transferred through the second conductive rod to the connecting rod, and then to the hinge shaft, thereby transferring to the vertical keel, further reducing the possibility of charge damaging the glass.

[0021] Optionally, a connecting shaft is rotatably mounted on the connecting rod, the second conductive rod is fixedly mounted on the connecting shaft, and a torsion spring is sleeved on the connecting shaft, with one side of the torsion spring mounted on the connecting shaft and the other side mounted on the connecting rod.

[0022] By adopting the above technical solution, when the connecting rod rotates toward the vertical keel, the second conductive rod is driven to rotate toward the direction away from the glass under the action of the torsion spring, which makes it easier for the second conductive rod to return to its initial position.

[0023] Optionally, a rubber pad is provided on the surface of the first conductive rod near the glass, and a sponge block is provided on the surface of the rubber pad facing the glass, with the sponge block abutting against the glass.

[0024] By adopting the above technical solution, when the first conductive rod slides towards the vertical keel, the second conductive rod drives the sponge block to slide. The sliding sponge block scrapes away the rainwater on the glass, reducing the attraction of the rainwater to the charge, thereby improving the safety of the glass. At the same time, the sponge block scrapes the glass, improving the cleanliness of the glass and improving the light transmittance of the glass.

[0025] Secondly, this application provides a construction method for a curtain wall with lightning protection structure, adopting the following technical solution:

[0026] Optionally, a construction method for a curtain wall with a lightning protection structure, using the aforementioned curtain wall with a lightning protection structure, further includes:

[0027] S1: Fix the vertical and horizontal keels to the main body of the building, fix the vertical and horizontal keels to each other, and weld the vertical and horizontal keels to the down conductor of the main body of the building.

[0028] S2: The glass is embedded in the rectangular frame formed by the vertical keel and the horizontal keel. Then the winding shaft is installed into the vertical keel. Then the first conductive rod is threaded onto the lead screw. Then the lead screw is installed in the horizontal keel.

[0029] S3: Fix the free end of the metal mesh to the first conductive rod, and install the rubber pad on the first conductive rod, then fix the sponge block on the rubber pad;

[0030] S4: A receiving groove is opened on the side of the vertical keel away from the main building. The hinge shaft, connecting rod and second conductive rod are installed in the receiving groove, and the connecting rope is connected between the second conductive rod and the hinge shaft.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. In the event of thunderstorms, the first driving component drives the first conductive rod to slide, which in turn moves the metal mesh. The metal mesh is unwound from the winding shaft. After the first conductive rod slides to the opposite vertical keel, the metal mesh lies flat on the glass. When rainwater on the glass attracts electrical charges, the charges move to the metal mesh and towards it. Once on the metal mesh, the charges move along the mesh's arrangement, towards the first conductive rod and the winding shaft, and then onto the vertical keel. From there, the charges are transferred to the building structure and down to the ground along the building's lower guide wire. This process reduces the likelihood of charges hitting the glass, thus reducing the possibility of breaking the glass. Simultaneously, the metal mesh, under the action of the winding shaft, maintains a certain distance from the glass, ensuring that when charges move towards the glass, they first pass through the metal mesh. As the charges pass through the metal mesh, they are transferred to the ground via the vertical keel, further enhancing the safety of the glass.

[0033] 2. The metal mesh is mesh-like, which allows light to enter the room through the mesh openings while conducting electricity, thus ensuring the brightness of the room. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0043] This application discloses a curtain wall with a lightning protection structure. (Refer to...) Figure 1 The curtain wall with lightning protection structure includes a curtain wall unit, which includes a horizontal keel 1 and a vertical keel 2 fixedly installed on the main body of the building. The horizontal keel 1 and the vertical keel 2 surround a rectangular frame. The curtain wall unit also includes glass installed in the rectangular frame. The horizontal keel 1 abuts against the opposite side wall of the vertical keel 2 and is fixedly installed on the vertical keel 2. Both the horizontal keel 1 and the vertical keel 2 are made of metal materials so as to transfer the charge to the main body of the building and then to the ground through the main body of the building.

[0044] Reference Figure 1 and Figure 2 In this embodiment, mounting grooves 3 are provided on the surfaces of the vertical keel 2 and the horizontal keel 1 that are close to each other. A winding shaft 4 is rotatably installed inside the vertical keel 2. The winding shaft 4 is located in the mounting groove 3 and is located on the side of the glass away from the main building body, at a distance of 10-20mm from the glass. The length direction and rotation axis of the winding shaft 4 are parallel to the length direction of the vertical keel 2. A metal mesh 5 is wound on the winding shaft 4. A first conductive rod 6 is fixedly installed at the free end of the metal mesh 5. The length direction of the first conductive rod 6 is parallel to the length direction of the winding shaft 4. The first conductive rod 6 is slidably installed in the mounting groove 3 of the horizontal keel 1. The sliding direction of the first conductive rod 6 is parallel to the length direction of the horizontal keel 1. The curtain wall also includes a first driving component for driving the first conductive rod 6 to slide and driving the metal mesh 5 to be laid on the glass.

[0045] During thunderstorms, the first driving component drives the first conductive rod 6 to slide, which in turn causes the metal mesh 5 to slide. The first conductive rod 6 slides into the mounting groove 3 of the corresponding vertical keel 2 and abuts against the bottom wall of the corresponding mounting groove 3, thus completing the laying of the metal mesh 5. When rainwater on the glass attracts charges from the air, the charges are transferred to the glass through the metal mesh 5. As the charges pass through the metal mesh 5, they are transferred to the metal mesh 5 and then to the vertical keel 2, and finally to the main building structure, thereby reducing the possibility of the charges penetrating the glass.

[0046] Reference Figure 1 and Figure 2Furthermore, a spring 7 is fitted onto the winding shaft 4. One side of the spring 7 is fixedly mounted on the winding shaft 4, and the other side is fixedly mounted on the side wall of the mounting groove 3. Under the action of the spring 7, it is easy to drive the winding shaft 4 to rotate and wind up the metal mesh 5.

[0047] Reference Figure 1 and Figure 2 In this embodiment, both ends of the first conductive rod 6 abut against the bottom wall of the mounting groove 3 of the transverse keel 1. The charge transferred by the metal mesh 5 is partially transferred to the transverse keel 1 through the first conductive rod 6, thus completing the charge transfer and further reducing the possibility of charge breakdown and glass breakage.

[0048] Reference Figure 1 and Figure 2 To ensure effective connection between the first conductive rod 6 and the vertical keel 2 for charge transfer, in this embodiment, the first conductive rod 6 has a rectangular cross-section. A metal rod 8 is fixedly installed on the side of the first conductive rod 6 away from the take-up shaft 4, with the length direction of the metal rod 8 perpendicular to the length direction of the first conductive rod 6. An insertion groove 9 is provided on the vertical keel 2 away from the take-up shaft 4 for the metal rod 8 to be inserted, and the inner diameter of the insertion groove 9 is equal to the inner diameter of the metal rod 8. When the metal rod 8 is inserted into the insertion groove 9, the charge is transferred to the vertical keel 2 through the metal rod 8, improving the charge transfer efficiency. Furthermore, the rectangular cross-section of the first conductive rod 6 increases the contact area between the first conductive rod 6 and the bottom wall of the mounting groove 3, further improving the charge transfer efficiency.

[0049] Reference Figure 2 and Figure 3 In this embodiment, the first driving component includes a first motor 10 disposed within the vertical keel 2. The first motor 10 is located within the mounting groove 3 of the vertical keel 2. A lead screw 11 is coaxially disposed on the output shaft of the first motor 10. The lead screw 11 is made of metal material and is located within the mounting groove 3 of the horizontal keel 1. The length direction of the lead screw 11 is parallel to the length direction of the horizontal keel 1. The end of the lead screw 11 facing away from the first motor 10 is rotatably disposed on the opposite vertical keel 2. A first conductive rod 6 is threadedly connected to the lead screw 11. When the first motor 10 is started, the first motor 10 drives the lead screw 11 to rotate. The rotation of the lead screw 11 causes the first conductive rod 6 to slide. The sliding of the first conductive rod 6 causes the metal mesh 5 to slide and be laid on the glass. The operation is simple and convenient.

[0050] Reference Figure 2 and Figure 3To reduce the impact of charge on the first motor 10, a mounting box 12 is provided inside the vertical keel 2. The mounting box 12 is fixedly installed in the mounting groove 3 of the vertical keel 2. The first motor 10 is fixedly installed inside the mounting box 12. The mounting box 12 has a through hole for the output shaft of the first motor 10 to move out. Insulating sleeves 13 are fixedly installed on both the inner and outer walls of the mounting box 12. Under the action of the insulating sleeves 13, the path of charge transferred to the first motor 10 is blocked, thereby reducing the possibility of damage to the first motor 10.

[0051] Reference Figure 2 and Figure 3 To reduce the possibility of charge being transferred to the first motor 10 via the lead screw 11, an insulating coupling is provided on the output shaft of the first motor 10, and the lead screw 11 is coaxially connected to the insulating coupling.

[0052] Reference Figure 1 and Figure 2 In this embodiment, a rubber pad 14 is fixedly disposed on the surface of the first conductive rod 6 near the glass, and a sponge block 15 is fixedly disposed on the surface of the rubber pad 14 facing the glass, with the sponge block 15 abutting against the glass. In rainy weather, when the first motor 10 drives the first conductive rod 6 to slide, the first conductive rod 6 drives the rubber pad 14 and the sponge block 15 to slide. The sliding sponge block 15 wipes the rainwater on the glass to separate the rainwater from the glass and reduce the attraction of the rainwater to the charge. At the same time, the sponge block 15 wipes the glass, improving the cleanliness of the glass.

[0053] Reference Figure 1 and Figure 2 To further reduce the impact of electric charge on the glass, a receiving groove 16 is provided on the side of the vertical keel 2 away from the main building. A lightning rod 17 is rotatably installed in the receiving groove 16. The lightning rod 17 is made of metal material. The length direction of the lightning rod 17 is parallel to the length direction of the vertical keel 2, and the rotation axis of the lightning rod 17 is perpendicular to the length direction of the vertical keel 2. A second driving component is provided on the vertical keel 2 to drive the lightning rod 17 to rotate.

[0054] Reference Figure 2 , Figure 3 and Figure 4 The second driving component includes a driving rod 18 rotatably disposed within the vertical keel 2. The length direction and rotation axis of the driving rod 18 are parallel to the length direction of the vertical keel 2. A first bevel gear 19 is coaxially disposed at both ends of the driving rod 18. The first motor 10 is a dual-axis motor. A second bevel gear 20 that meshes with the first bevel gear 19 is disposed on the output shaft of the first motor 10 away from the lead screw 11. Furthermore, the second bevel gear 20 is made of insulating material. A hinge shaft 21 is rotatably disposed on the vertical keel 2. A lightning rod 17 is disposed on the hinge shaft 21. A third bevel gear 22 that meshes with the first bevel gear 19 is sleeved on the hinge shaft 21.

[0055] When the first motor 10 is working, the first motor 10 drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the drive rod 18 to rotate. The rotation of the drive rod 18 drives the first bevel gear 19 on the other side to rotate. The first bevel gear 19 drives the third bevel gear 22 to rotate. The rotation of the third bevel gear 22 drives the hinge shaft 21 to rotate, which in turn drives the lightning rod 17 to rotate. The lightning rod 17 rotates outward in a direction away from the vertical keel 2, so that the end of the lightning rod 17 is away from the vertical keel 2. When the charge is transferred towards the curtain wall, the charge first passes through the lightning rod 17 and is transferred to the lightning rod 17. The charge is then transferred through the lightning rod 17 to the hinge shaft 21 and then to the vertical keel 2.

[0056] Reference Figure 4 and Figure 5 To further improve the protective effect of the lightning rod 17 on the glass, the lightning rod 17 includes a connecting rod 171 mounted on a hinge shaft 21 and a second conductive rod 172 rotatably mounted on the connecting rod 171. The rotation axis of the second conductive rod 172 is perpendicular to the length direction of the hinge shaft 21. A connecting shaft 173 is rotatably mounted on the connecting rod 171, and the length direction of the connecting shaft 173 is perpendicular to the length direction of the hinge shaft 21. The second conductive rod 172 is fixedly mounted on the connecting shaft 173. A connecting rope 174 is wound on the hinge shaft 21, and the free end of the connecting rope 174 is fixedly mounted on the second conductive rod 172. The hinge shaft 21 drives... When the connecting rod 171 rotates away from the vertical keel 2, the hinge shaft 21 winds up the connecting rope 174, causing the second conductive rod 172 to rotate toward the glass. When the first motor 10 drives the hinge shaft 21 to rotate, the hinge shaft 21 rotates and winds up the connecting rope 174. The winding of the connecting rope 174 causes the second conductive rod 172 to rotate toward the connecting rod 171, making the second conductive rod 172 closer to the glass. When the charge is transferred to the curtain wall, because the second conductive rod 172 is located at the front end of the metal mesh 5, the charge is first transferred to the second conductive rod 172 and then transferred to the vertical keel 2 through the second conductive rod 172, further improving the safety of the glass.

[0057] To facilitate the rotation of the second conductive rod 172 to its initial position (the second conductive rod 172 is coaxial with the connecting rod 171), a torsion spring is sleeved on the connecting shaft 173, with one side of the torsion spring on the connecting shaft 173 and the other side on the connecting rod 171.

[0058] The implementation principle of a curtain wall with lightning protection structure in this application embodiment is as follows:

[0059] During thunderstorms, the first motor 10 is started, which drives the lead screw 11 to rotate. The rotation of the lead screw 11 causes the first conductive rod 6 to slide, and the sliding of the first conductive rod 6 causes the metal mesh 5 to slide and be laid on the glass.

[0060] At the same time, when the first motor 10 is working, the first motor 10 drives the second bevel gear 20 to rotate, the second bevel gear 20 rotates and drives the first bevel gear 19 to rotate, the first bevel gear 19 rotates and drives the drive rod 18 to rotate, the drive rod 18 rotates and drives the first bevel gear 19 on the other side to rotate, the first bevel gear 19 drives the third bevel gear 22 to rotate, the third bevel gear 22 rotates and drives the hinge shaft 21 to rotate, which in turn drives the lightning rod 17 to rotate. The lightning rod 17 rotates out in a direction away from the vertical keel 2, so that the end of the lightning rod 17 is away from the vertical keel 2.

[0061] Furthermore, the hinge shaft 21 rotates to wind up the connecting rope 174, and the winding of the connecting rope 174 causes the second conductive rod 172 to rotate toward the connecting rod 171, so that the second conductive rod 172 is close to the glass.

[0062] When the charge is transferred to the curtain wall, because the second conductive rod 172 is located at the front end of the metal mesh 5, the charge is first transferred to the second conductive rod 172 and then transferred to the vertical keel 2 through the second conductive rod 172; part of the charge is transferred to the metal mesh 5 and then transferred to the vertical keel 2 through the metal mesh 5, thereby reducing the possibility of breaking the glass.
