Traditional keel structures are typically made of metal or wood and fixed to the wall via welding or bolts, with the wall panels then secured to the keel using clips or screws. In recent years, with the development of industrialized construction, higher demands have been placed on the installation efficiency, stability, and adjustability of exterior wall panels.

[0003] A search revealed Chinese Patent Publication No. CN220814682U, which discloses a prefabricated external wall panel connection structure. This structure includes an adjustment component positioned on the wall panel near the outer keel and a connecting component positioned on the adjustment component. The adjustment component includes a horizontal plate positioned on top of the outer keel and a vertical plate positioned on top of the horizontal plate. The horizontal and vertical plates are perpendicular to each other, and the vertical plate slides against the wall panel. The connecting component is used to fix the horizontal plate to the outer keel. This application improves the efficiency of installing external wall panels.

[0004] In practical use, the aforementioned device exists, with the connecting component used to fix the horizontal plate to the outer keel. This application has the effect of improving the efficiency of installing external wall panels, but while it achieves rapid installation through prefabricated modules, its adjustment range is limited and it is difficult to adapt to complex wall structures. Therefore, a keel structure for external wall panels is proposed to solve the above problems. Utility Model Content

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides an embodiment of a keel structure for an external wall panel, comprising a wall 1, providing structural stability and load-bearing capacity. A fixing mechanism 2 is provided on the outer front side of the wall 1, and a bracket 3 is fixedly connected to the outer adjacent side of the fixing mechanism 2. The bracket 3 is designed to provide good support capacity. A support mechanism 4 is provided on the adjacent side of the bracket 3, and a sound insulation board 6 is fixedly connected to the adjacent side of the bracket 3. The sound insulation board 6 is used to reduce the propagation of sound and improve the sound insulation performance of the external wall panel.

[0043] The support mechanism 4 includes two vertical support rods 41 for providing vertical support. The bottoms of the two vertical support rods 41 are fixedly connected to the inner bottom wall of the bracket 3, providing good support force. Multiple limiting grooves 42 are formed inside the two vertical support rods 41, providing good locking ability through the support of the vertical support rods 41. Fixed posts 46 are slidably connected inside the multiple limiting grooves 42, designed to provide good locking ability and slide within the limiting grooves 42. A sliding connection includes a placement bracket 45, designed to provide good support, allowing the inner bottom wall of the placement bracket 45 to support the outer side of the secondary keel. A limiting rod 47, rectangular in shape, is fixedly connected to the outside of the fixed column 46. When the fixed column 46 slides inside the limiting groove 42, it can drive the limiting rod 47 to slide into the limiting groove 42. A locking bracket 44 is fixedly connected to the outside of the fixed column 46, designed to provide good limiting capability. The fixed column 46 can drive the locking bracket 44 to slide outside the vertical support rod 41. The inner side of the bracket 3... The bracket 3 is slidably connected to a sliding assembly 5. Multiple horizontal support rods 43 are fixedly connected to the outer adjacent side of the sliding assembly 5. These support rods, in conjunction with the vertical support rods 41, enhance the supporting force. The sliding assembly 5 includes multiple placement blocks 501, designed to provide ample transport space, allowing the ends of the horizontal support rods 43 to slide within the placement blocks 501 and combine with the vertical support rods 41. The multiple placement blocks 501 are fixedly connected to the outer front side of the bracket 3. Sliding grooves 502 are provided on both sides of the inner wall of the bracket 3, designed to provide ample sliding space. Multiple sliding blocks 503 are slidably connected inside the sliding groove 502. The sliding space provided by the sliding groove 502 allows the sliding blocks 503 to slide smoothly. The outer adjacent sides of the multiple sliding blocks 503 are respectively fixedly connected to the outer sides of the horizontal support rod 43. The sliding blocks 503 drive the horizontal support rod 43 to slide, so that the horizontal support rod 43 can be adjusted to different heights. The outer side of the vertical support rod 41 is on the outer front side of the locking frame 44. The outer side of the locking frame 44 can be locked at the intersection of the vertical support rod 41 and the horizontal support rod 43.

[0044] Specifically, the bracket 3 provides a good support frame. Then, the horizontal support rod 43 can be placed inside the bracket 3 by the placement block 501. The sliding groove 502 inside the sliding groove 502 is connected to the horizontal support rod 43. The sliding groove 502 can drive the horizontal support rod 43 to slide inside the sliding groove 502. Then, the vertical support rod 41 is installed on the inner bottom wall of the bracket 3. After installation, the outside of the fixing column 46 is slid manually inside the horizontal support rod 43 and the limiting groove 42, so that the locking frame 44 can be locked at the intersection of the horizontal support rod 43 and the vertical support rod 41. At the same time, when the fixing column 46 slides, the limiting rod 47 can slide along inside the limiting groove 42, thereby improving the fixing ability. Its design can fix the horizontal support rod 43 after adjustment, so that it can be adjusted for different walls. After installation, by sliding the placement frame 45 outside the fixing column 46, the secondary keel can be placed on the inner bottom wall of the placement frame 45.

[0045] Reference Figure 2 and Figure 3 The fixing mechanism 2 includes multiple support blocks 21, designed to provide good support capacity. The support blocks 21 are externally fixedly connected to the front exterior of the wall 1. Alignment holes 22 are provided inside the support blocks 21, designed to provide good alignment. A connecting plate 24 is slidably connected to the outside of the alignment holes 22, designed to provide good connection. Multiple right-angle grooves 26 are provided inside the connecting plate 24. By sliding the right-angle grooves 26 to the outside of the support blocks 21, the weight of the connecting plate 24 itself causes the support blocks 21 to engage in the grooves at the top, enabling initial... The bracket 3 is fixed in place. Multiple right-angle grooves 26 are externally slidably connected to the outside of the support block 21. Multiple threaded holes 25 are opened inside the multiple connecting plates 24. The threaded holes 25 are connected to the alignment holes 22 by bolts, so that the connecting plates 24 can be fixed and the bracket 3 can be prevented from shifting. Support blocks 23 are fixedly connected to the rear side of the multiple connecting plates 24. The design allows a certain gap to be created between the connecting plates 24 and 1. The outside of the multiple support blocks 23 is on the top of the support block 21. The outside of the support blocks 23, that is, the side away from the connecting plates 24, is in contact with the front side of the wall 1.

[0046] Specifically, by engaging the right-angle slot 26 inside the connecting plate 24, the bracket 3 can be initially engaged and fixed to the connecting plate 24. Then, by passing the bolt through the threaded hole 25 and rotating it into the alignment hole 22, the connecting plate 24 can be fixed. This design can increase the fixation of the bracket 3 and prevent displacement during use. At the same time, the engagement of the right-angle slot 26 with the support block 21 can enable quick positioning and installation of the bracket 3.

[0047] Working Principle: First, the bracket 3 provides basic support for the entire device. Through the support of the bracket 3, the horizontal support rod 43 is placed inside the bracket 3 and fixed by the placement block 501. Both ends of the horizontal support rod 43 are slidably connected to the inside of the placement block 501, forming a combined support structure with the vertical support rod 41. Next, the sliding block 503 inside the sliding groove 502 is connected to the horizontal support rod 43, allowing the horizontal support rod 43 to slide within the sliding groove 502. Driven by the sliding block 503, the horizontal support rod 43 can be adjusted at different heights to adapt to different wall requirements. After the vertical support rod 41 is installed on the inner bottom wall of the bracket 3, the fixing column 46 is manually slid into the horizontal support rod 43 and the limiting groove 42. The sliding of the fixing column 46 causes the limiting rod 47 to slide within the limiting groove 42, thereby improving the fixing ability. Meanwhile, the external sliding connection of the fixed column 46 is the locking bracket 44, which can lock into the intersection of the vertical support rod 41 and the horizontal support rod 43 to ensure the stability of the support structure. Finally, the placement bracket 45 is slidably connected to the outside of the fixed column 46 to support the secondary keel. Through the inner bottom wall of the placement bracket 45, the secondary keel is fixed in the appropriate position, thereby completing the installation and support functions of the entire device. At the same time, the sound insulation performance of the device is further improved by the setting of the sound insulation panel 6.

[0048] During installation, the right-angle slot 26 is first engaged with the inside of the connecting plate 24, providing a foundation for subsequent installation steps. Next, the connecting plate 24 is further secured by passing bolts through the threaded holes 25 on the connecting plate 24 and rotating them to engage with the alignment holes 22 on the support block 21. This step not only enhances the fixation of the bracket 3 but also effectively prevents misalignment during use. Simultaneously, the design of the support block 23 creates a gap between the connecting plate 24 and the wall 1, facilitating the installation and adjustment of the bracket 3. The outer surface of the support block 23 fits snugly against the outer front side of the wall 1, providing additional stability to the entire device. Throughout the installation process, the engagement design of the right-angle slot 26 and the support block 21 allows for rapid positioning and installation of the bracket 3, significantly improving installation efficiency. This design enables the bracket 3 to be installed quickly and accurately, facilitating subsequent construction.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
