[0001] This utility model relates to the field of building construction technology, specifically to a curved decorative panel connection structure. Background Technology

[0002] With the increasing diversification of modern architectural forms, curved shapes are being used more and more widely in building facades and interior decoration. Alloy gypsum decorative panels, due to their advantages such as lightweight, high strength, fire resistance, weather resistance, and high plasticity, have become one of the materials used in the construction field. However, in existing technologies, the connection between curved and flat decorative panels, and the connection between curved and curved decorative panels, have the following significant drawbacks:

[0003] Welding process failure: Due to the limitations of material composition, alloy gypsum board cannot be welded together. Traditional metal plate welding processes (such as argon arc welding of aluminum plates) are completely ineffective, resulting in the reliance on purely mechanical fixation at the joints, which leads to insufficient structural strength and poor durability. Furthermore, existing mechanical connections mostly use exposed screws or rivets for fixation, resulting in visible fasteners at the joints, which disrupts the smoothness of the curved surface and affects the overall aesthetics of the decorative panel.

[0004] Therefore, there is an urgent need to develop a non-welding, structurally reliable curved decorative panel connection structure that ensures the overall aesthetic appeal of the decorative panel. Utility Model Content

[0041] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] The curved decorative panel connection structure of this application can be applied to occasions such as connecting curved decorative panels with other decorative panels, and of course it can also be used in other similar application scenarios. The following is a detailed description of a curved decorative panel connection structure.

[0043] Example 1

[0044] See appendix Figure 1 — Figure 6The diagram shows a preferred embodiment of a curved decorative panel connection structure according to this application. The curved decorative panel connection structure includes a first decorative panel body 1 and a second decorative panel body 2, with a connection structure provided on the back of the first decorative panel body 1 and the back of the second decorative panel body 2; wherein at least one of the first decorative panel body 1 and the second decorative panel body 2 is a curved decorative panel; wherein the connection structure includes a first connection feature 3 and a second connection feature 4, and the first connection feature 3 is integrally formed with the first decorative panel body 1, and the second connection feature 4 is integrally formed with the second decorative panel body 2; for ease of description, this embodiment is described using the example of the first connection feature 3 being integrally formed with the first decorative panel body 1 and the second connection feature 4 being integrally formed with the second decorative panel body 2.

[0045] This invention utilizes a connection structure divided into a first connection feature 3 and a second connection feature 4. This allows for the connection of two decorative panel bodies without welding. The first connection feature 3 and the second connection feature 4 are respectively positioned on the back of the two decorative panel bodies, enabling a non-welding connection. This allows the entire connection structure to be concealed on the back of the decorative panel bodies, preventing disruption to the smoothness of the curved surface and ensuring the overall aesthetics of the decorative panel. Furthermore, the two connection feature parts are integrally formed with the two decorative panel bodies, ensuring the connection strength. It should be noted that the first connection feature 3 can also be integrally formed with the second decorative panel body 2; in this case, the second connection feature 4 is integrally formed with the first decorative panel body 1.

[0046] See appendix Figure 1 — Figure 6 As shown, in this utility model, the second connecting feature 4 includes mating plates 41 evenly spaced on the second decorative panel body 2, and through grooves 42 on the mating plates 41; the first connecting feature 3 can pass through the through grooves 42 to connect the first decorative panel body 1 and the second decorative panel body 2; wherein, the first connecting feature 3 includes insert blocks 31 evenly spaced on the first decorative panel body 1, and rotating locking grooves 32 on both sides of the root of the insert blocks 31. It should be noted that the width of the through groove 42 is greater than the width of the insert blocks 31, and the height of the through groove 42 is greater than the thickness of the insert blocks 31, but less than the maximum thickness of the insert blocks 31 after rotational deformation, that is, after the worker rotates and deforms the insert blocks 331 with tools, the insert blocks 331 cannot be rotated to separate from the locking grooves 32.

[0047] This invention provides the foundation for the through groove 42 by using a mating plate 41. Through the mating of the through groove 42 and the insert block 31, the insert block 31 deforms after being inserted into the through groove 42, preventing it from separating from the through groove 42, thus connecting the first decorative panel body 1 and the second decorative panel body 2. By providing rotating locking grooves 32 on both sides of the base of the insert block 31, the insert block 31 can now rotate clockwise or counterclockwise, rotating around the part of the insert block 31 that connects to the first decorative panel body 1. This ensures that the insert block 31 contacts the opening of the through groove 42, resulting in more even force distribution and increased connection strength. It should be noted that the insert block 31 and the first decorative panel body 1 are integrally formed.

[0048] See appendix Figure 1 — Figure 6 As shown, in this utility model, the length of the rotating snap-fit ​​groove 32 is not greater than one-third of the length of the plug-in block 31 and not less than one-fifth of the length of the plug-in block 31, and the height of the rotating snap-fit ​​groove 32 is not less than the thickness of the mating plate 41.

[0049] This invention limits the length of the rotating snap-fit ​​groove 32 to ensure that the plug-in block 31 can rotate while preventing the connection length between the plug-in block 31 and the first decorative panel body 1 from being too short and breaking during the rotation of the plug-in block 31. This ensures the connection strength between the plug-in block 31 and the first decorative panel body 1, thereby ensuring the connection strength between the first decorative panel body 1 and the second decorative panel body 2. By limiting the groove height of the rotating snap-fit ​​groove 32 and the thickness of the mating plate 41, this invention ensures that the plug-in block 31 will not interfere with the mating plate 41 when it rotates, and ensures that the mating plate 41 can be located in the rotating snap-fit ​​groove 32.

[0050] See appendix Figure 1 — Figure 6 As shown, the usage process of the connection structure of this utility model is as follows:

[0051] First, align the insert block 31 on the first decorative panel body 1 with the mating plate 41 on the second decorative panel body 2. Then, align the insert block 31 with the through groove 42 on the mating plate 41 and insert it so that the insert block 31 passes through the through groove 42 and the first decorative panel body 1 and the second decorative panel body 2 are tightly attached. At this time, use a tool to bend and rotate the part of the mating plate 41 with the rotating snap groove 32 so that the insert block 31 and the through groove 42 of the mating plate 41 are deformed, and the insert block 31 and the mating plate 41 form a tenon joint. Finally, apply sealant to the connection structure to form a seal and prevent rainwater from entering.

[0053] See appendix Figure 7 — Figure 10 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the second connecting feature 4 includes a mating plate 41 disposed on the second decorative panel body 2 and a through hole 43 disposed on the mating plate 41; while the first connecting feature 3 includes a first bent portion 33 disposed on the first decorative panel body 1, a second bent portion 34 disposed on the first bent portion 33, a snap-fit ​​groove 35 disposed at equal intervals on the second bent portion 34, a connector 36 installed in the snap-fit ​​groove 35, and a locking member 37 installed on the connector 36; wherein, the second bent portion 34 is in close contact with the mating plate 41. It should be noted that, in this embodiment, the second connecting feature 4 can also be disposed on the first decorative panel body 1, in which case the first connecting feature 3 is disposed on the second decorative panel body 2. It should be noted that, the diameter of the through hole 43 is larger than the diameter of the connecting rod 362 in the connector 36, so as to facilitate the insertion of the connecting rod 362 into the through hole 43.

[0054] This utility model connects the mating plate 41 and the second bent portion 34 by providing a through hole 43, which cooperates with the connector 36 and the locking member 37, thereby connecting the first decorative panel body 1 and the second decorative panel body 2; the snap-fit ​​groove 35 is used to snap the connector 36, so that the connector 36 can be installed on the second bent portion 34, and the connector 36, together with the locking member 37, can connect the second bent portion 34 and the mating plate 41.

[0055] See appendix Figure 7 — Figure 10 As shown, in this utility model, the first bending portion 33 bends inward into the body of the first decorative panel, and the first bending portion 33, together with the second bending portion 34 and the inner wall of the body of the first decorative panel 1, forms an installation groove 38 for installing the connector 36. The connector 36 includes a limiting head 361 and a connecting rod 362 disposed on the limiting head 361. The connecting rod 362 can pass through the snap-fit ​​groove 35 and the through hole 43 to connect with the locking member 37. It should be noted that the thickness of the limiting head 361 is not greater than the width of the installation groove 38, thereby ensuring that the limiting head 361 can be located in the installation groove 38. Furthermore, the size of the limiting head 361 is larger than the size of the snap-fit ​​groove 35, thereby ensuring that the limiting head 361 cannot pass through the snap-fit ​​groove 35, ensuring that the limiting head 361 can be located within the installation groove 38. Then, the connecting rod 362 is passed through the snap-fit ​​groove 35 and the through hole 43, and finally locked by the locking member 37.

[0056] See appendix Figure 7 — Figure 10As shown, in this utility model, the connecting rod 362 and the locking member 37 are connected by threads, which makes it easy to install the locking member 37 on the connecting rod 362. The locking member 37 can be a nut, and the connecting rod 362 can be a screw.

[0057] See appendix Figure 7 — Figure 10 As shown, the usage process of this embodiment is as follows:

[0058] First, the connector 36 is installed in the mounting groove 38 and the snap-fit ​​groove 35, that is, the limiting head 361 of the connector 36 is located in the mounting groove 38, and the connecting rod 362 is set through the snap-fit ​​groove 35. Then, the through hole 43 on the mating plate 41 is aligned with the connecting rod 362, and the connecting rod 362 is inserted into the through hole 43. Then, the locking member 37 is threadedly connected to the connecting rod 362, so that the second bent part 34 is connected to the mating plate 41, that is, the first decorative panel body 1 is connected to the second decorative panel body 2. Finally, sealant is applied to the connection structure to form a seal and prevent rainwater from entering.

[0059] Example 3

[0060] See appendix Figure 11 — Figure 16 As shown, the difference between this embodiment and embodiment 2 is that, in this embodiment, the outer wall of the connecting rod 362 is smooth, and the connecting rod 362 is provided with an insertion hole 363; the locking member 37 is provided with an movable hole 371 corresponding to the connecting rod 362, and the side wall of the locking member 37 is provided with a mating hole 372, in which a limiting pin 373 corresponding to the insertion hole 363 is movably installed; the head of the limiting pin 373 is provided with a guide surface 374.

[0061] In this embodiment, the outer wall of the connecting rod 362 is smooth to facilitate the connection between the locking member 37 and the connecting rod 362; the limiting pin 373 can limit the connection between the connecting rod 362 and the locking member 37 when it is inserted into the mating hole 372 and the insertion hole 363; the guide surface 374 facilitates the insertion of the limiting pin 373 into the mating hole 372 and the insertion hole 363.

[0062] It should be noted that the connecting rod 362 can be rectangular, square, or other shapes, so that when the locking member 37 is fitted onto the connecting rod 362, the locking member 37 will not rotate, making it easy to connect the mating hole 372 with the insertion hole 363 and to facilitate the insertion of the limit pin 373.

[0063] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
