[0025] The following is a specific embodiment of the present application, and the technical scheme of the present application is further described in conjunction with the drawings, but the present application is not limited to these embodiments.

[0026] A whole adjustment type aluminum pull net plate curtain wall is installed on a building structure, as shown in the figure, comprising at least two mutually parallel keels 1, in the present application, the keels 1 are all horizontally arranged. The installation mode of the keels 1 on the building structure is not limited, for example, in some embodiments, the building structure comprises a plurality of vertical columns, the keels 1 are directly or through connecting members installed on the columns, and the specific installation mode can refer to the prior art, which will not be described here. Figure 1 A plurality of curtain walls are arranged between the adjacent two keels 1 to form the outer facade decoration of the building structure, and the upper and lower ends of the curtain wall are respectively connected with the keels 1, and the left and right ends are respectively abutted with the adjacent curtain walls. Among them, in order to make the curtain wall show more visual effects, obtain more ventilation and lighting effects, and facilitate cleaning of the outward side of the curtain wall, two or more curtain walls (such as three, four, or even all the curtain walls) are rotatably arranged between the two keels 1, and in the present application, rotatable means that the curtain wall rotates around its vertical center axis. The selection of the rotatable curtain wall is related to the position of the column and the installation mode of the column and the keel 1. For example, in some embodiments, the keel 1 is directly installed on the column, so that the curtain wall located at the column lacks the space for inward rotation, and therefore cannot be set as rotatable; the opening is usually formed between the two columns, so that the curtain wall located at the opening can be set as rotatable and opened by rotating to realize ventilation and lighting. In some embodiments, the keel 1 is connected with the column through a long connecting member, which provides a space for the inward rotation of the curtain wall located at the column, so that the curtain wall can all be set as rotatable, which can further improve the ventilation and lighting effects and improve the integrity of the outer facade.

[0027] The rotatable curtain wall all adopts the aluminum pull net plate 2, which is made of aluminum with various patterns and styles, is easy to install, has a very beautiful appearance, and can resist natural storms and other weather due to its metal stability. The aluminum pull net plate 2 has a relatively light weight, which is convenient for rotation. In some embodiments, the surface of the aluminum pull net plate 2 is provided with a fluorocarbon coating to improve the weather resistance, corrosion resistance and self-cleaning property of the curtain wall, and the attachment of the fluorocarbon coating is usually realized by spraying.

[0028] ​

[0029] The two ends of the central axis of the aluminum screen plate 2 in the vertical direction are respectively provided with rotating parts 21, and the aluminum screen plate 2 is rotatably connected with the keel 1 through the rotating parts 21. The design of the rotating part 21 is not limited, and in some embodiments, the rotating part 21 is a rotating shaft, including a connecting shaft fixedly arranged on the aluminum screen plate 2, and a sleeve rotatably arranged outside the connecting shaft, and the sleeve is fixedly connected with the keel 1; wherein, in some embodiments, the keel 1 is provided with a fixed groove for the sleeve to be inserted. In other embodiments, the rotating part 21 can be a fixed groove arranged on the aluminum screen plate 2, and the keel 1 is fixedly provided with a connecting shaft which can be inserted into the fixed groove.

[0030] In order to control the rotation of the aluminum screen plate 2 when necessary, a driving structure for driving a plurality of aluminum screen plates 2 to rotate simultaneously is further included. In principle, the driving structure can be arranged in any way, for example, in some embodiments, a gear and chain structure can be used: a gear is arranged on the rotating part 21, a gear is arranged on the output shaft of the motor, and the gears of a plurality of aluminum screen plates 2 and the gear of the motor output shaft are engaged through a chain, and the chain is driven to rotate by the motor, thereby driving the gears and the aluminum screen plates 2 to rotate.

[0031] For example, in other embodiments, in order to ensure the stability and reliability of the driving, and to avoid affecting the appearance of the building facade, as shown in Figure 2 and Figure 3 , the driving structure first includes a transmission connecting rod 31, which can be made of an aluminum alloy rod as the main body, having the characteristics of high strength, light weight, corrosion resistance and longer service life. A plurality of aluminum screen plates 2 are respectively hingedly connected with the transmission connecting rod 31 through connecting arms 22, and it is expected that the movement of a transmission connecting rod 31 will drive a plurality of aluminum screen plates 2 to move simultaneously. The connecting arm 22 serves to keep a certain distance between the transmission connecting rod 31 and the aluminum screen plate 2, so as to avoid the position conflict between the transmission connecting rod 31 and the aluminum screen plate 2 in the closed state of the aluminum screen plate 2.

[0032] One end of the connecting arm 22 is fixedly connected with the aluminum screen plate 2, and in principle, the connecting position of the connecting arm 22 on the aluminum screen plate 2 is not limited, but in order to improve the transmission efficiency, in some embodiments, one end of the aluminum screen plate 2 in the horizontal direction is hingedly connected with the transmission connecting rod 31 through the connecting arm 22, that is, the end of the aluminum screen plate 2 is taken as the driving end, which has a longer force arm and makes the driving of the aluminum screen plate 2 more relaxed. In some embodiments, as shown in Figure 1 , since the aluminum screen plate 2 includes a frame and an aluminum screen part arranged in the frame, as shown in Figure 2As shown, the connecting arm 22 is connected to the frame at the end of the aluminum mesh plate 2. Furthermore, the connecting arm 22 is connected to the upper or lower edge of the frame of the aluminum mesh plate 2, reducing the obstruction of the opening that the aluminum mesh plate 2 opens after rotation. In some embodiments, the connecting arm 22 is perpendicular to the plane containing the aluminum mesh plate 2, resulting in higher force transmission efficiency between the connecting arm 22 and the transmission link 31 and the aluminum mesh plate 2.

[0033] The other end of the connecting arm 22 is hinged to the transmission link 31. The hinged connection method is not limited; in some embodiments, such as... Figure 3 and Figure 4 As shown, the transmission connecting rod 31 has a sliding groove 311, and the connecting arm 22 has a through hole. It also includes a T-shaped nail and a fixing plate. The T-shaped nail is a common market fastening accessory that offers economic benefits. It consists of a vertically connected mounting strip 4 and a mounting plate. The mounting strip 4 passes through the sliding groove 311 and the through hole of the connecting arm 22 before connecting to the fixing plate. Simultaneously, the mounting plate abuts against the transmission connecting rod 31. The fixing plate is fastened to the transmission connecting rod 31 with bolts, completing the installation of the connecting arm 22 on the transmission connecting rod 31. The through hole of the connecting arm 22 can rotate around the mounting strip 4 to achieve a hinged connection. The sliding groove 311 has a certain length along the length of the transmission connecting rod 31 to allow the connecting arm 22 to be adjusted to a suitable installation position. The T-shaped nail, fixing plate, and bolts can all be made of corrosion-resistant or galvanized materials, providing good strength and ensuring a long service life.

[0034] The drive structure further includes a drive component for driving the transmission link 31 to move in both a first direction and a second direction; the first direction is horizontal and perpendicular to the keel 1, i.e., as shown in the figure. Figure 2 The top-down direction in the top view; the second direction is horizontal and parallel to keel 1, i.e. Figure 2 The left and right directions in a top view. For example... Figure 2 As shown, when the transmission link 31 moves to the right and downward, it drives the aluminum mesh panel 2 from the open state to the closed state. When the transmission link 31 moves to the left and upward, it drives the aluminum mesh panel 2 from the closed state to the open state. During operation, the transmission link 31 always moves horizontally and will not move vertically, preventing it from moving to the opening created by the rotation of the aluminum mesh panel 2, thus avoiding affecting aesthetics and ventilation / lighting effects.

[0035] The structure of the drive component is not limited; however, to simplify the structure and improve drive efficiency, in some implementations, such as... Figure 2 As shown, the driving component includes a lever 32, which includes an active part 321 and a passive part 322. The active part 321 is hinged to the keel 1, and the hinge method is not limited; for example, it can be as follows: Figure 2The keel 1 is fixedly equipped with a connecting keel, which is perpendicular to the keel 1 and located on the horizontal plane where the keel 1 is located. The free end of the connecting keel is vertically connected to a fixed shaft, and a sleeve is fitted on the fixed shaft through a rotating bearing. The active part 321 is connected to the sleeve. The keel 1 is fixed, and the lever 32 can rotate with the hinge point between its active part 321 and the keel 1 as the fulcrum. When rotating, the passive part 322 of the lever 32 rotates on the horizontal plane, and its coordinate position changes.

[0036] In order for the passive part 322 to drive the transmission link 31 to move, the driving component also includes a connecting block 33. One end of the connecting block 33 is hinged to the passive part 322, and the other end is disposed on the transmission link 31. In use, the passive part 322 has a tendency to drive the connecting block 33 and the transmission link 31 to rotate, but because the transmission link 31 is restrained by several aluminum mesh plates 2, it cannot rotate accordingly. Therefore, under the action of hinge, only displacement occurs in the first direction and the second direction.

[0037] In order to accommodate different rotation angles, the position of the connecting block 33 or the transmission link 31 relative to the driving part 321 in the second direction should be adjustable. For example, assuming that the positions of the connecting block 33 and the transmission link 31 relative to the driving part 321 are fixed, when... Figure 2 As shown, and in accordance with Figure 2 In the direction of rotation, when lever 32 rotates upward, connecting block 33 and transmission rod 31 move upward and to the left, the distance between the hinge point of transmission rod 31 and connecting arm 22 and the rotation center axis of aluminum mesh plate 2 increases. Rotation alone cannot compensate for this distance, causing aluminum mesh plate 2 to move to the right. Therefore, in some embodiments, connecting block 33 can be slidably mounted on transmission rod 31 along the second direction, i.e., the length direction of transmission rod 31. Based on the groove 311 provided on transmission rod 31, connecting block 33 is slidably mounted in the groove 311, and transmission rod 31 slides relative to connecting block 33, i.e., relative to active part 321. When... Figure 2 As shown, and in accordance with Figure 2 In the direction of rotation, when lever 32 rotates upward, connecting block 33 moves upward and a short distance to the left. Driven by connecting block 33, transmission link 31 moves upward and a short distance to the left, and, constrained by the aluminum mesh plate 2, autonomously moves further to the left relative to connecting block 33. This ensures that the distance between the hinge point of transmission link 3 and connecting arm 22 and the rotation center axis of aluminum mesh plate 2 remains unchanged, allowing aluminum mesh plate 2 to rotate smoothly in its original position. In other embodiments, such as... Figure 2In this structure, lever 32 is a telescopic rod, which includes a fixed cylinder and a movable rod slidably inserted into the fixed cylinder. The active part 321 is located on the fixed cylinder, and the passive part 322 is located on the movable rod. Therefore, the distance between the passive part 322 and its hinged connecting block 33 relative to the active part 321 can vary. Figure 2 As shown, and in accordance with Figure 2 In the direction of rotation, when lever 32 rotates upward, connecting block 33 moves upward and a short distance to the left under the influence of lever 32. Based on the restraint of transmission link 31 and aluminum mesh plate 2, telescopic rod retracts, and connecting block 33 moves further to the left. Similarly, this keeps the distance between the hinge point of transmission link 3 and connecting arm 22 and the rotation center axis of aluminum mesh plate 2 unchanged, allowing aluminum mesh plate 2 to rotate smoothly in its original position. Preferably, the telescopic rod is an electrically operated telescopic rod, actively extending and retracting to match the rotation angle.

[0038] The structure of the drive body that controls the rotation of lever 32 is not limited. It can be electrically controlled by a drive motor, for example, by connecting the sleeve rotatably connected to the fixed shaft of the connecting keel to the output shaft of the drive motor through a gear meshing structure; it can also be manually controlled by setting a drive rod, for example, by setting a drive rod on the sleeve; or it can be a motor with manual adjustment space. This design can refer to the electric-manual composite drive motor in the prior art. The specific structure will not be described here.

[0039] This type of integrated adjustable aluminum mesh curtain wall is installed as follows: Step 1: First, install and position the curtain wall's exterior keel 1, accurately position the aluminum mesh panels 2 on the keel 1, and use the rotating part 21 on the frame of the aluminum mesh panels 2 to rotatably but not horizontally install them with the keel 1. Step 2: After the aluminum mesh panels 2 are installed on the keel 1, assemble the drive body, lever 32, and connecting block 33 and install them on the inner end of the keel 1, while reserving a signal transmission device for later connection. Step 3: Take out the transmission rod 31, fix one end of the connecting block 33 to the transmission rod 31, and test the motor by driving the transmission rod 31 to ensure normal opening and closing. Step 4: After passing T-shaped nails through the transmission rod 31 and the connecting arm 22 of the aluminum mesh panels 2, align the fixing pieces, and use bolts to fix the aluminum mesh panels 2 to the transmission rod 31, then perform another transmission test.
