[0026] Example 1

[0027] This embodiment proposes a large-span curtain wall panel system, such as... Figures 1 to 2As shown, it includes a panel 4, an external frame 6, and a frame mounting assembly. The external frame 6 is detachably mounted on the panel 4 via the frame mounting assembly. The frame mounting assembly includes a hook-shaped screw 8, a connecting angle steel 7, a double nut 11, and an adjusting shim 10. A through hole is opened at a preset position on the connecting angle steel 7. The hook-shaped screw 8 includes a hook part 81 and a threaded rod body 82 connected to each other.

[0028] like Figure 1 As shown, a flexible pad 9 is provided between the top of the external frame 6 and the bottom of the panel 4, and a connecting angle steel 7 is welded to the bottom of the external frame 6; an adjusting shim 10 is placed between the double nut 11 and the connecting angle steel 7, and the adjusting shim 10 has a small hole. Figure 2 As shown, the overall shape of the external frame 6 is consistent with that of the panel 4, forming an integrated rectangular frame structure arranged along the circumference of the panel 4. Alternatively, the external frame 6 can be arranged in several intervals along the circumference of the panel 4, forming a distribution structure consistent with the shape of the panel 4, according to actual needs.

[0029] In the installed state, the top of the external frame 6 is attached to the surface of the panel 4, and the bottom is fixedly connected to the connecting angle steel 7. The through hole on the connecting angle steel 7 is located on the outside of the external frame 6. The hook part 81 of the hook-shaped screw 8 is hooked onto the edge of the panel 4, and one end of the threaded rod 82 passes through the through hole and is locked to the connecting angle steel 7 by double nuts 11, so that the top of the external frame 6 is supported on the lower end of the panel 4. The hook part 81 and the external frame 6 are located on opposite sides of the panel 4. Preferably, the external frame 6 and the threaded rod 82 form a multi-point contact, forming a three-sided support structure, which can better provide the panel 4 with higher stability and load-bearing capacity.

[0030] In this embodiment, the connecting angle steel 7 includes two sides forming a right-angle structure. One side is connected to the outer frame 6 and has a through hole, while the other side is perpendicular to the bottom. The connecting angle steel 7 is preferably fixed to the bottom of the outer frame 6 by welding. The edge of the panel 4 is provided with a mounting portion 40 perpendicular to the large-span surface, and the hook portion 81 of the hook-shaped screw 8 is hooked onto the mounting portion 40. This design is also suitable for panels 4 with flat edges; the fixing method is the same, except that when applied to the latter, the hook portion 81 of the hook-shaped screw 8 is directly hooked onto the edge of the panel 4, and a flexible gasket can be added at the contact point between the hook portion 81 and the panel 4.

[0031] The system's operation process in the factory includes:

[0032] Weld the connecting angle steel 7 onto the external frame 6;

[0033] Place the flexible pad 9 between the outer frame 6 and the panel 4, and align one side of the outer frame 6 with the panel 4.

[0034] The bottom end of the threaded rod 82 of the hook-shaped screw 8 is passed through the through hole opened on the connecting angle steel 7 and the small hole opened on the adjusting shim 10 in sequence. Its hook part 81 is locked onto the panel 4. Tighten the double nut 11 to fix the panel 4 on the outer frame 6. The top of the outer frame 6 is supported on the lower end of the panel 4, and the panel 4 is installed in place.

[0035] The hook-shaped screw 8 is detachable, making the connection between the external frame 6 and the panel 4 convenient and flexible. After the panel 4 is installed in this way, the quality of the large-span curtain wall panel system can be fully protected during the transportation from the factory to the site for installation.

[0036] Example 2

[0037] Figures 3 to 6 This embodiment presents a view of a large-span curtain wall panel system in a field installation scenario, including a panel 4, curtain wall studs 1 disposed on both sides of the panel 4, and an external frame 6. The same panel 4, external frame 6, and frame installation components as in Embodiment 1 are used. The curtain wall studs 1 are installed on the edge of the panel 4 using multiple stud installation components to connect two panels 4. The number and position of the curtain wall studs 1 are designed according to the specific building curtain wall installation specifications. The external frame 6 is installed circumferentially on the panel 4, providing support and protection for the panel 4.

[0038] In this embodiment, the keel installation assembly includes a support bracket 5, a plug-in bracket 3, and screws 2. The top end of the support bracket 5 is locked to the bottom of the curtain wall keel 1 by screws 2, and the bottom end of the support bracket 5 is fixedly connected to the mounting part 40 of a panel 4. The support bracket 5 also has an extension portion facing the plug-in bracket 3. The top end of the plug-in bracket 3 is provided with a groove that mates with the extension portion, and the bottom end of the plug-in bracket 3 is fixedly connected to the mounting part 40 of another panel 4. In this embodiment, the top end and the extension portion of the support bracket 5 are both flat plate structures and are connected as one piece by a bending structure.

[0039] Specifically, such as Figure 5 and Figure 6As shown, the support bracket 5 includes a first vertical plate 51, a first horizontal plate 52, and a second horizontal plate 53. The bottom end of the first vertical plate 51 is connected to the left side panel 4, and the top end of the first vertical plate 51 is fitted with the first horizontal plate 52. The first horizontal plate 52 is screwed to the curtain wall keel 1. The bottom end of the first horizontal plate 52 is located near the side of the plug-in bracket 3, and the second horizontal plate 53 is lower than the first horizontal plate 52. The other end of the second horizontal plate 53 is a free end, serving as an extension. The plug-in bracket 3 includes a second vertical plate 31 and a groove 32. The bottom end of the second vertical plate 31 is connected to the right side panel 4, and the top end of the second vertical plate 31 is fitted with the groove 32. A slot is formed in the groove 32, and a limiting sliding member 33 is provided in the slot. The second horizontal plate 53 is inserted into the limiting sliding member 33. The bottom end of the support bracket 5 and the bottom end of the plug-in bracket 3 are connected to the mounting part 40 of the corresponding panel 4 by an adjustable bolt structure, such as the first bolt 30 and the second bolt 50.

[0040] The on-site installation process for this large-span curtain wall panel system includes the following steps:

[0041] Install curtain wall keel 1 and connect adjacent panels 4.

[0042] like Figure 3 As shown, the left panel 4 is first installed and fixed to the curtain wall keel 1 by the support bracket 5 in the curtain wall installation assembly. Then, the right panel 4 is initially installed to the curtain wall keel 1 by the plug-in bracket 3. The bottom end of the plug-in bracket 3 is connected to the mounting part 40 of the right panel 4 by the first bolt 30. Up to this step, the external frame 6 has not been removed, so the panel 4 is protected throughout the entire installation process.

[0043] Remove the external frame 6 and adjust the position of the adjacent panels 4.

[0044] After completing the connection between the curtain wall keel 1 and the adjacent panel 4, the frame installation components at the connection between the two panels 4 are removed. Specifically, the double nuts 11 at the bottom of the hook-shaped screw 8 are loosened, and the hook portion 81 of the hook-shaped screw 8 is rotated to pull it out of the gap between the mounting portions 40 of the two panels 4. The hook-shaped screw 8 is then disengaged from the panel 4. The other hook-shaped screws 8 are removed in this manner, separating the external frame 6 from the panel 4. Figure 3 Become Figure 4 The structure shown.

[0045] Then, continue adjusting the first bolt 30 to shorten the distance between the plug-in hanger 3 and the support hanger 5, ensuring a full fit between the two structures and allowing the right-side panel 4 to reach the precise position. After the panel 4 is installed, use the hook-shaped screw 8 to loosen the external frame 6 from the panel 4. The removed external frame 6 can be transported back to the factory for reuse.

[0046] Furthermore, since the external frame 6 protects the panel 4, the anti-deformation effect of the panel 4 during processing, transportation, and installation does not need to be achieved through the internal frame. The internal frame of the panel 4 only needs to consider the requirements after installation, thus reducing the use of the internal frame and reducing resource waste.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
