Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a quick connection node structure between exterior facade panels and cantilevered steel structures. Background Technology

[0002] In the field of modern architecture, especially in curtain wall engineering, the connection nodes between the facade panels and the cantilevered steel structure are crucial structural links. These nodes not only need to bear the huge load of the panels themselves, but also need to effectively resist the stress caused by wind load, seismic action and temperature changes. Traditional connection node structures usually use welding or a large number of bolts to fix the panels to the steel frame. At the factory or on-site, pre-installed connectors are welded or drilled on the cantilevered steel structure according to the design location. Then, the facade panels with matching openings or channels are hoisted to the predetermined position. Finally, the panels are manually positioned and secured to the steel structure connectors using bolt sets or special clamps. During the installation process, the three-dimensional position is continuously adjusted and corrected to ensure the overall flatness and line requirements of the facade. However, the connection node structure does not have an auxiliary structure. When assembling and aligning the connectors and plates, operators often need to manually support the bolts or connectors, which is not only time-consuming and laborious, but also very easy for the bolts to tilt due to unstable grip or slight collision in the narrow high-altitude working space. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quick connection node structure between the facade panel and the cantilever steel structure, which can effectively solve the problems mentioned in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a quick connection node structure for an exterior facade panel and a cantilevered steel structure, including an exterior facade panel body and a rotating plate. The cantilevered steel structure body overlaps the exterior facade panel body, and a connecting plate is connected inside the cantilevered steel structure body. A limiting plate is fixedly connected to the right side of the exterior facade panel body. A sliding groove is provided above the cantilevered steel structure body, and an adjustment structure is provided above the cantilevered steel structure body. A locking plate is slidably connected inside the rotating plate, and a locking structure is provided inside the rotating plate. The locking structure includes a fixing plate, a positioning plate, and an inclined plate. A moving rod is connected to one side of the inclined plate, and a spring is sleeved on the moving rod. An inclined edge is provided above the positioning plate.

[0005] Furthermore, a convex groove is provided on the right side of the exterior facade panel body, a convex block is connected to the left side of the cantilever steel structure body, the clamping plate is clamped inside the limiting plate, and the rotating plate overlaps outside the limiting plate.

[0006] Furthermore, the fixing plate is fixedly connected inside the rotating plate, the positioning plate is fixedly connected above the fixing plate, and the inclined plate is snapped into the positioning plate.

[0007] Furthermore, the moving rod is slidably connected inside the clamping plate, the inclined plate is connected outside the clamping plate by a spring, and the positioning plate is clamped inside the clamping plate.

[0008] Furthermore, the adjustment structure includes a vertical plate, a concave plate, and a motor. The motor is connected to one side of the vertical plate, the vertical plate is connected above the cantilevered steel structure body, and a threaded rod is rotatably connected inside the vertical plate.

[0009] Furthermore, the output shaft of the motor is connected to the threaded rod, the concave plate is threaded to the outside of the threaded rod, and a slider is connected below the concave plate.

[0010] Furthermore, the rotating plate is rotatably connected to the concave plate, and the slider is slidably connected to the slide groove.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By setting up a limiting plate, a clamping plate, a rotating plate, and a snap-fit ​​structure, when the rotating plate overlaps with the limiting plate after flipping, a pushing force is applied to the clamping plate. When the clamping plate slides inside the rotating plate, it will interlock with the limiting plate. When the inclined side contacts the inclined plate, the inclined plate will drive the moving rod to move outward. When the inclined plate moves, it will cause the spring to deform. When the clamping plate moves to the appropriate position, the inclined plate will be snapped into the positioning plate by the action of the spring. This connection node structure, through the cooperation between the positioning plate, the inclined plate, and the spring, can provide auxiliary support for the connection between the cantilever steel structure and the exterior facade panel. When assembling and aligning the connectors and panels, the operators do not need to manually support the bolts or connectors, thereby reducing subsequent operation procedures and improving the flexibility of the connection node structure.

[0012] 2. By setting up an adjustment structure, the threaded rod is driven by a motor to rotate, and the concave plate slides on the surface of the threaded rod. The slider below the concave plate moves in the groove. When the concave plate moves to the appropriate position, the rotating plate is manually driven to flip inside the concave plate. This achieves precise and stepless adjustment of the connection node in the horizontal direction. It not only significantly reduces the difficulty and time cost of manual positioning, but also effectively avoids installation errors caused by repeated manual adjustments, greatly improving the efficiency and overall flatness of the facade panel installation.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example 1: Reference Figure 1-4This is the first embodiment of the present invention, which discloses a quick connection node structure for an exterior facade panel and a cantilevered steel structure. It includes an exterior facade panel body 1 and a rotating plate 11. The exterior facade panel body 1 is overlapped with a cantilevered steel structure body 2. A connecting plate 5 is connected inside the cantilevered steel structure body 2. A limiting plate 4 is fixedly connected to the right side of the exterior facade panel body 1. A sliding groove 10 is provided above the cantilevered steel structure body 2. An adjustment structure 7 is provided above the cantilevered steel structure body 2. A locking plate 9 is slidably connected inside the rotating plate 11. A locking structure 8 is provided inside the rotating plate 11. The locking structure 8 includes a fixing plate 801, a positioning plate 802 and an inclined plate 803. A moving rod 804 is connected to one side of the inclined plate 803. A spring 805 is sleeved on the moving rod 804. An inclined edge 806 is provided above the positioning plate 802.

[0019] A convex groove 3 is provided on the right side of the exterior panel body 1, a convex block 6 is connected to the left side of the cantilever steel structure body 2, a clamping plate 9 is clamped in the limiting plate 4, a rotating plate 11 overlaps the limiting plate 4, a fixing plate 801 is fixedly connected in the rotating plate 11, a positioning plate 802 is fixedly connected above the fixing plate 801, an inclined plate 803 is clamped in the positioning plate 802, a moving rod 804 is slidably connected in the clamping plate 9, the inclined plate 803 is connected to the outside of the clamping plate 9 by a spring 805, and the positioning plate 802 is clamped in the clamping plate 9.

[0020] By setting up a snap-fit ​​structure 8 consisting of a fixed plate 801, a positioning plate 802, an inclined plate 803, a moving rod 804, and a spring 805, the connection node achieves rapid mechanical locking and reliable load bearing. When the snap-fit ​​plate 9 is pushed into the limiting plate 4, the inclined plate 803 slides along the preset inclined side 806 of the positioning plate 802 and compresses the spring 805 to store energy. After the snap-fit ​​plate 9 is fully in place, the spring 805 instantly rebounds and drives the inclined plate 803 to accurately snap into the locking groove of the positioning plate 802. A clear mechanical sound indicates that the installation is in place. This eliminates the tedious process of manually supporting the bolts in traditional installation. Furthermore, the unique inclined self-locking mechanism forms a reliable anti-vibration and anti-wind load capacity. While ensuring convenient installation, it significantly improves the safety and durability of the node, making it particularly suitable for complex construction environments such as high-altitude operations.

[0021] Example 2: Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The adjustment structure 7 includes a vertical plate 701, a concave plate 702, and a motor 705. The motor 705 is connected to one side of the vertical plate 701, which is connected above the cantilevered steel structure body 2. A threaded rod 704 is rotatably connected inside the vertical plate 701. The output shaft of the motor 705 is connected to the threaded rod 704. The concave plate 702 is threaded to the outside of the threaded rod 704. A slider 703 is connected below the concave plate 702. A rotating plate 11 is rotatably connected inside the concave plate 702, and the slider 703 is slidably connected inside the slide groove 10.

[0022] By setting up an electric adjustment structure 7 consisting of a motor 705, a threaded rod 704, a vertical plate 701, and a slider 703, precise remote control and intelligent positioning of the connection nodes are achieved. The motor 705 drives the precision threaded rod 704 to move the concave plate 702 smoothly. The dual guiding system formed by the slider 703 and the slide groove 10 ensures the stability and accuracy of the adjustment process. It can be remotely controlled from a safe position on the ground to achieve millimeter-level fine adjustment of the spatial position of the connection point, completely avoiding the safety risks of manual positioning at high altitudes. It has good error compensation capabilities and can effectively eliminate the accumulated deviations in the early construction, ensuring the overall flatness of the facade installation.

[0023] The remaining structure is the same as that in Example 1.

[0024] The workflow of this utility model is as follows: When the connection node structure is being assembled, the cantilevered steel structure body 2 can slide in the convex groove 3 through the convex block 6. When the cantilevered steel structure body 2 overlaps with one side of the exterior panel body 1, the threaded rod 704 is driven to rotate by the motor 705, and the concave plate 702 will slide on the surface of the threaded rod 704. The slider 703 below the concave plate 702 will move in the slide groove 10. When the concave plate 702 moves to the appropriate position, the rotating plate 11 is manually driven to flip in the concave plate 702. When the rotating plate 11 overlaps with the limiting plate 4 after flipping, a pushing force is applied to the clamping plate 9. When the clamping plate 9 slides inside the rotating plate 11, it will intersect with the limiting plate 4. When the inclined side 806 contacts the inclined plate 803, the inclined plate 803 will drive the moving rod 804 to move outward. When the inclined plate 803 moves, it will drive the spring 805 to deform. When the clamping plate 9 moves to the appropriate position, the inclined plate 803 is clamped into the positioning plate 802 by the action of the spring 805.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
