[0042] Example 1

[0043] Reference Figures 1-3 As shown, this embodiment provides an eaves panel system, including purlins 1, auxiliary panels 2, molding strips 3, sliding components 4, and metal roof panels 5. The purlins 1 are installed on the interior side of the roof's exterior wall. The auxiliary panels 2 are mounted on the purlins 1 and extend towards the exterior side of the roof's exterior wall to form an extension section 21.

[0044] The pressure strip 3 is pressed onto the auxiliary panel 2, positioned above the purlin 1 and connected to it. A first connecting screw 31 can be used to pass through the pressure strip 3, auxiliary panel 2, and purlin 1 to clamp and fix the auxiliary panel 2 to the purlin 1. Therefore, the pressure strip 3 has protrusions 32 facing away from the auxiliary panel 2. It should be noted that the number and position of the protrusions 32 correspond to the locking edge 51 of the metal roof panel 5. The sidewall of the protrusions 32 has locking grooves 33.

[0045] The sliding assembly 4 includes a sliding support 41 and an auxiliary plate 42. The sliding support 41 is slidably mounted on the extension section 21, and multiple sliding supports 41 are arranged along the extension direction of the purlin 1. The auxiliary plate 42 is connected to multiple sliding supports 41 respectively.

[0046] The metal roof panel 5 is connected to the auxiliary panel 42, allowing the connection position of the metal roof panel 5 to be moved to the outdoor extension section 21, thus eliminating the need for openings indoors and reducing the risk of indoor water seepage. Since the sliding support 41 is slidably installed on the extension section 21, it can slide relative to the extension section 21. When the metal roof panel 5 deforms due to thermal expansion and contraction, it can drive the sliding support 41 to slide, thereby reducing the risk of damage to the metal roof panel 5. The side of the metal roof panel 5 is provided with a locking edge 51, and a locking strip 52 is connected to the side wall of the locking edge 51. The locking strip 52 is slidably engaged in the locking groove 33. The locking groove 33 limits the locking edge 51, improving the installation reliability of the metal roof panel 5, and allowing it to move relative to the pressure strip 3 when the metal roof panel 5 deforms, preventing damage to the metal roof panel 5.

[0047] It should be noted that in this embodiment, the sliding direction of the sliding support 41 and the sliding direction of the locking edge 51 are the same.

[0048] The eaves panel system provided in this embodiment connects the auxiliary panel 2 to the purlin 1 via the pressure strip 3, and connects the metal roof panel 5 to the extension section 21 of the auxiliary panel 2 via the sliding component 4, thereby transferring the opening position of the metal roof panel 5 to the outside and reducing the risk of indoor water seepage. Furthermore, by sliding the locking strip 52 on the locking edge 51 with the locking groove 33 on the pressure strip 3, the reliability of the metal roof panel 5 after installation can be improved. On the other hand, with the cooperation of the sliding component 4, the deformation difference caused by thermal expansion and contraction of the metal roof panel 5 can be absorbed, making the eaves structure more stable.

[0049] Specifically, the lock bar 52 includes a lock head 521 and connecting edges 522 located on both sides of the lock head 521; the lock head 521 protrudes towards the side wall of the lock edge 51, and the connecting edges 522 are connected to the side wall of the lock edge 51. Specifically, the connecting plate can be welded to or bonded to the lock edge 51 to improve the reliability of the connection between the lock bar 52 and the lock edge 51.

[0050] Specifically, the lock head 521 has a cavity filled with a rubber column 523. The lock bar 52 is a thin metal sheet. This allows the lock head 521 to undergo a certain elastic deformation when inserted into the lock groove 33, forming an interference fit between the lock head 521 and the lock groove 33, which can improve the connection stability to a certain extent.

[0051] Specifically, refer to Figure 5 As shown, the outer contour surface of the lock head 521 has an arc greater than 180°; the lock groove 33 includes a sliding cavity 331 and an opening 332, and the inner wall of the sliding cavity 331 has an arc greater than 180°, so that the lock head is locked in the sliding cavity 331. This ensures that the lock head 521 will not easily disengage after being inserted into the lock groove 33.

[0052] Specifically, the outer side of the opening 332 is provided with a guiding arc surface 333, which facilitates the insertion of the lock head 521 into the lock groove 33.

[0053] Specifically, refer to Figure 5 As shown, the top of the protrusion 32 is provided with a groove 34, and the groove 34 contains a first connecting screw 31, which passes through the pressure strip 3, the auxiliary panel 2, and the purlin 1.

[0054] Specifically, refer to Figure 4The sliding support 41 includes a base plate 411, a support plate 412, and a top plate 413. The support plate 412 connects the base plate 411 and the top plate 413 respectively. The base plate 411 has an elongated hole 414, through which a bolt 415 passes and through the auxiliary panel 2, and is then connected to a nut. This allows the support to slide relative to the auxiliary panel 2.

[0055] Specifically, the auxiliary panel 42 sequentially includes a first part 421, a second part 422, a third part 423, and a fourth part 424; the metal roof panel 5 is connected to the first part 421; the second part 422 is connected to the first part 421 via a transition part 425, making the height of the second part 422 lower than that of the first part 421; the second part 422 is connected to the top plate 413; the third part 423 is bent from the edge of the second part 422 and abuts against the support plate 412; the fourth part 424 is bent from the edge of the third part 423 and abuts against the bottom plate 411. The third part 423 of the auxiliary panel 2 can partially cover the gap between the metal roof panel 5 and the sliding support. Specifically, the metal roof panel 5 and the first connecting part can be connected using a second connecting screw 43.

[0056] Specifically, a reinforcing plate 416 is also provided between the support plate 412 and the base plate 411.

[0057] Installation process: Place the auxiliary panel 2 on the purlin 1 and secure the pressure strip 3. Connect the pressure strip 3, auxiliary panel 2, and purlin 1 using the first connecting screw 31. Install the sliding support 41 onto the extension section 21 of the auxiliary panel 2, and install the auxiliary panel 2 onto the sliding support 41 using screws. Finally, install the metal roof panel 5, ensuring that the lock head 521 on the side wall of the lock edge 51 engages with the lock groove 33, and install the metal roof panel 5 onto the auxiliary panel 42 using screws.

[0058] 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.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
