Technical Field

[0001] The utility model belongs to the technical field of building exterior wall decoration, and particularly relates to a wood-plastic exterior wall panel and an installation structure thereof. Background Art

[0002] With the development of modern architectural decoration technology, exterior wall panels, as one of the primary decorative materials for building exteriors, are widely used in various types of buildings to enhance their aesthetics, weather resistance, and thermal insulation. However, traditional exterior wall panels often suffer from complex installation, insufficient structural stability, and inconvenient maintenance, which bring many inconveniences to practical applications.

[0003] The installation of external wall panels currently on the market typically relies on direct fastening of the keel to the panels. This method of installation presents limitations in terms of panel stability and firmness. When subjected to external forces or after prolonged use, the panels can become loose or shaken, compromising the building's safety and aesthetics. Furthermore, traditional external wall panels are cumbersome to disassemble, making maintenance and replacement difficult. This is especially true when replacing individual panels, which often requires disassembling multiple connections, increasing maintenance complexity and time costs. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a wood-plastic exterior wall panel and its installation structure, which can achieve stable installation of the wall panel by optimizing the installation structure and improving the connection method, and facilitate subsequent maintenance and disassembly, thereby ensuring the stability and convenience of the wall panel in long-term use.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A wood-plastic exterior wall panel comprises a keel fixed to an exterior wall and a profile connected to the outside of the keel, wherein the profile is shaped as a cavity structure with two ends open, and partition plates are fixedly connected to the inside of the profile at equal intervals;

[0007] Inner lining strips are arranged opposite to each other on the inner side walls of the profile member.

[0008] A wood-plastic exterior wall panel installation structure, the technical key points of which are: comprising a fixing bracket, a U-shaped piece and a locking piece located between a keel and a profile member for connecting them;

[0009] The fixing bracket is connected to the keel;

[0010] The U-shaped member is fixedly connected to the profile member via a locking member;

[0011] The U-shaped piece and the locking piece are both engaged with the fixing bracket.

[0012] Furthermore, first bolt holes are formed through the upper end surface of the keel at equal intervals;

[0013] The fixing bracket includes a clamping piece clamped on the keel, and a second bolting hole corresponding to the first bolting hole is formed through the top of the clamping piece;

[0014] A bolt is connected in the second bolt hole.

[0015] Furthermore, an oblique support rod is fixedly connected to the outer side of the engaging member, and a supporting groove is provided at one end of the oblique support rod;

[0016] The locking member comprises a threaded column, and both ends of the threaded column are snapped into the supporting groove.

[0017] Furthermore, a through hole is formed through the side surface of the profile;

[0018] Both ends of the U-shaped member are penetrated by recessed holes corresponding to the through holes;

[0019] The threaded column passes through the countersunk hole and the through hole.

[0020] Furthermore, a blocking piece is fixedly connected to the threaded column;

[0021] A gasket is sleeved on the threaded column and inserted into the sink hole;

[0022] The other end of the threaded column is connected with a nut.

[0023] Furthermore, a positioning protrusion is fixedly connected to the outer side of the U-shaped member, and the shape of the positioning protrusion is set to be hemispherical;

[0024] A positioning hole corresponding to the positioning protrusion is opened on the outer side of the keel.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] In this utility model, the provision of fixing brackets, U-shaped members, and locking members achieves a secure connection between the keel, profile, and exterior wall. In particular, the use of bolts, coupled with the snap-fitting members and the keel's bolting holes, ensures a tight fit between the fixing brackets and the keel. This significantly improves the overall stability of the exterior wall panel when subjected to wind loads or external forces, effectively preventing loosening and shaking of the panels and enhancing their durability and safety.

[0027] The structural design's coordinated use of diagonal braces and support slots allows the threaded studs to securely fit within the support slots. Furthermore, the snap-fit ​​structures at both ends of the threaded studs securely connect the U-shaped pieces and profiles to the keel. This design not only reduces installation complexity but also creates a reliable snap-fit ​​between the fixed brackets, U-shaped pieces, and locking elements, preventing loosening and shaking of the profiles under external forces, ensuring the wall panels remain stable over long-term use.

[0028] Furthermore, the combined design of the threaded post, baffle, washer, and nut ensures a more secure installation. The washer is embedded in the countersunk hole, preventing wear from direct metal friction and helping to extend the service life of the threaded post and U-shaped fitting. This structure also allows for quick removal of the profile from the keel by simply loosening the nut and pulling it up when maintenance is required, greatly facilitating maintenance and replacement operations and improving ease of use and efficiency.

[0029] The cavity structure of the profile and the setting of the partition plate effectively reduce the deadweight of the wall panel and improve the bending strength of the structure, thus ensuring the stability and firmness of the profile in long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0046] See Figure 1-7 A wood-plastic exterior wall panel and its installation structure include a keel 1 fixed to the exterior wall and a profile 5 connected to the outside of the keel 1; a fixing bracket 2, a U-shaped member 3 and a locking member 4 are provided between the keel 1 and the profile 5 for connecting them; the fixing bracket 2 is used to secure the keel 1 to the exterior wall, ensuring the stability and firmness of the exterior wall panel installation structure; the U-shaped member 3 is firmly connected to the profile 5 through the locking member 4, thereby achieving a firm positioning of the profile 5 on the keel 1; the U-shaped member 3 and the locking member 4 are engaged with the fixing bracket 2, and a stable connection structure is formed through the close cooperation of the three, so that the exterior wall panel is not easy to loosen or shake when subjected to external force.

[0047] See Figure 1-4 The upper end surface of the keel 1 is provided with first bolt holes 11 at equal intervals for connection with the fixing bracket 2; the fixing bracket 2 includes a clamping piece 21 that is engaged with the keel 1, and a second bolting hole 211 corresponding to the first bolting hole 11 is formed on the top of the clamping piece 21 so that the two are tightly fitted and connected; a bolt 23 is connected to the second bolting hole 211, and the bolt 23 secures the clamping piece 21 to the keel 1 through the docking of the bolting holes, thereby making the installation of the fixing bracket 2 and the keel 1 more secure and avoiding the problem of displacement or loosening under the action of external force.

[0048] See Figure 3-4 The outer side of the engaging member 21 is fixedly connected with a diagonal support rod 22; one end of the diagonal support rod 22 is provided with a supporting groove 221; the supporting groove 221 is used to engage with the threaded column 41; the locking member 4 includes a threaded column 41, and the two ends of the threaded column 41 are firmly connected to the fixed bracket 2 by being engaged in the supporting groove 221; the design of the diagonal support rod 22 not only enhances the supporting role of the engaging member 21, but also improves the deformation resistance of the overall structure, making the external wall panel more stable during long-term use.

[0049] See Figure 5-7 A through hole 51 is formed on the side of the profile 5; countersunk holes 32 corresponding to the through holes 51 are formed at both ends of the U-shaped member 3; the threaded column 41 passes through the countersunk hole 32 and the through hole 51, thereby realizing the connection between the U-shaped member 3 and the profile 5; the design of the threaded column 41 ensures the stable positioning of the U-shaped member 3, and the alignment of the through hole 51 and the countersunk hole 32 enables the threaded column 41 to be reliably fixed in the profile 5 without displacement or loosening.

[0050] See Figure 6 A baffle 411 is fixedly connected to the threaded column 41; the baffle 411 is located between the countersunk hole 32 and the through hole 51, and is used to enhance the stability of the threaded column 41; and a gasket 42 is relatively sleeved on the threaded column 41, and the gasket 42 is inserted into the countersunk hole 32. The design of the gasket 42 avoids direct metal contact between the threaded column 41 and the U-shaped part 3, thereby reducing the possibility of wear and loosening; the other end of the threaded column 41 is connected to a nut 43, and by tightening the nut 43, the threaded column 41 can be firmly maintained in a predetermined position, effectively preventing the profile part 5 from displacement or vibration during use.

[0051] See Figure 3 and Figure 5 A positioning protrusion 31 is fixedly connected to the outer side of the U-shaped part 3; the positioning protrusion 31 is hemispherical in shape and plays a role in positioning and limiting; a positioning hole 12 corresponding to the positioning protrusion 31 is opened on the outer side of the keel 1.

[0052] See Figure 7 The shape of the profile 5 is designed to be a cavity structure with openings at both ends. The cavity structure can effectively reduce the deadweight of the profile 5 while ensuring the integrity of its internal space; the interior of the profile 5 is fixedly connected with dividing plates 52 at equal intervals, and the dividing plates 52 are used to strengthen the internal support structure of the profile 5, so that it has higher bending resistance and stability after installation; inner lining strips 53 are relatively arranged on the inner side walls of the profile 5, and the inner lining strips 53 facilitate the later installation of a reinforced inner lining steel frame inside the profile 5.

[0053] The working principle of this utility model is:

[0054] During installation, first snap the engaging member 21 onto the keel 1, and align the second bolting hole 211 with the first bolting hole 11. Then, fasten the engaging member 21 and the keel 1 with the bolt 23.

[0055] After the fixing bracket 2 is installed, the keel 1 is fixed to the exterior wall using expansion bolts;

[0056] Snap the U-shaped member 3 onto the profile member 5, aligning the countersunk hole 32 with the through hole 51. Then, insert the threaded column 41 through the partition plate 52 and the through hole 51, and insert the gasket 42 into the countersunk hole 32. Finally, install the nut 43 on the threaded column 41 and tighten the nut 43 to secure the threaded column 41 to the profile member 5.

[0057] Finally, hold the profile 5 with your hands, allow the two ends of the threaded column 41 to be inserted into the locking piece 21, and allow the positioning protrusion 31 to be inserted into the positioning hole 12. Through the engagement of the threaded column 41 and the supporting groove 221 and the cooperation of the positioning protrusion 31 and the positioning hole 12, the profile 5 can be prevented from shaking during use. At the same time, during later maintenance, you only need to hold the profile 5 with your hands and pull it online to quickly remove the profile 5 from the keel 1.
