[0036] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] refer to Figure 1 and Figure 2 As shown, an embodiment of this application provides a wall keel structure 100, which includes a plurality of first keel members 110, a plurality of second keel members 120, a magnetic member 121, and a plurality of decorative sheets 130. The plurality of first keel members 110 are all installed on the wall 200. Each of the second keel members 120 is engaged with the side of the first keel member 110 away from the wall 200 to form a snap-fit ​​structure. The second keel member 120 and the first keel member 110 are staggered. The first keel member 110 is installed on the wall 200. The gap 131 between the first keel member 110 and the decorative sheet 130 facilitates wiring installation and air circulation. The second keel member 120 can be connected with the first keel member 110 to form a snap-fit ​​structure, so that the second keel member 120 and the first keel member 110 are fixed and limited to each other, making installation more convenient and improving installation efficiency. The staggered arrangement of the second keel member 120 and the first keel member 110 can distribute the load, reduce local stress concentration, make the connection between the second keel member 120 and the first keel member 110 more stable, and improve space utilization.

[0038] In this embodiment, the magnetic component 121 is disposed on the side of the second keel component 120 opposite to the first keel component 110. Each of the decorative sheets 130 is magnetically connected to the second keel component 120 via the magnetic component 121. The second keel component 120 is located between the first keel component 110 and the decorative sheet 130, and a gap 131 exists between the first keel component 110 and the decorative sheet 130. Correspondingly, the decorative sheet 130 and the second keel component 120 are magnetically connected via the magnetic component 121. The magnetic component 121 provides a fixed support point to facilitate the installation and connection of the decorative sheet 130, making the installation and replacement of the decorative sheet 130 more convenient.

[0039] refer to Figure 7 As shown, for example, the second keel member 120 is made of ferromagnetic material, such as iron, steel or carbon steel. The magnetic member 121 can be bonded to the decorative sheet 130. The decorative sheet 130 can be magnetically connected to the second keel member 120 made of ferromagnetic material through the magnetic member 121, thereby installing and connecting the decorative sheet 130.

[0040] The total thickness of the magnetic component 121 is 2.05 mm. The magnetic component 121 includes a magnetic adhesive layer, a first adhesive layer, and a first release film. The thickness of the magnetic adhesive layer is 1.35 mm, the thickness of the first adhesive layer is 0.55 mm, and the thickness of the first release film is 0.15 mm. For example, the width of the magnetic component 121 is 30 mm, or the width of the magnetic component 121 is 60 mm. When the number of decorative sheets 130 is greater than or equal to three, the width of the magnetic component 121 is 60 mm to ensure that the magnetic component 121 has a better magnetic attraction and fixing effect on the decorative sheets 130.

[0041] like Figure 2 , Figure 4 and Figure 5 As shown, the wall joist structure 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the wall joist structure 100, the second direction Y refers to the height direction of the wall joist structure 100, and the third direction Z refers to the width direction of the wall joist structure 100. It is understood that the above definitions are only for the purpose of understanding the relative positional relationships of the various parts of the wall joist structure 100 and should not be construed as limiting this application.

[0042] Decorative sheet 130 is used to decorate architectural spaces and serve a protective function. Decorative sheet 130 can be sintered stone, which has a smooth and flat surface, delicate texture, and can imitate the texture of various materials such as stone and wood. It has the characteristics of high strength, wear resistance, stain resistance, and fire resistance. The sintered stone is large in size and has fine edge treatment to achieve lightweight installation and seamless laying. Of course, decorative sheet 130 can also be made of other sheet-like decorative materials.

[0043] In one embodiment, alternatively, referencing Figure 2 and Figure 3 As shown, a first keel member 110 is provided with a plurality of first snap-fit ​​parts 111, which are arranged along the first direction X, that is, the plurality of first snap-fit ​​parts 111 are arranged along the length direction of the wall keel structure 100, so that the plurality of first snap-fit ​​parts 111 are respectively used to connect and fix the second keel member 120, thereby improving the connection stability between the first keel member 110 and the second keel member 120.

[0044] Optionally, such as Figure 3 and Figure 4 As shown, the second keel member 120 is provided with a first slot 122. Two adjacent first engaging parts 111 are engaged into one first slot 122, and the first engaging parts 111 are engaged with the side wall of the first slot 122. Correspondingly, one first slot 122 corresponds to two first engaging parts 111, so that the two first engaging parts 111 are engaged with the side wall of the first slot 122 respectively, thereby engaging the first keel member 110 and the second keel member 120. Of course, the first engaging parts 111 can be separated from the first slot 122 to realize the separation between the first keel member 110 and the second keel member 120.

[0045] In one embodiment, alternatively, referencing Figure 2 and Figure 3 As shown, there are multiple second keel members 120. These multiple second keel members 120 are spaced apart along the first direction X, so that multiple first snap-fit ​​portions 111 of one first keel member 110 can correspond to multiple second keel members 120. That is, multiple second keel members 120 are spaced apart along the length of the wall keel structure 100, which reduces the heat conduction effect, plays a certain role in heat preservation and prevents condensation, and avoids the decorative sheet 130 from becoming damp. The multiple second keel members 120 magnetically attract the decorative sheet 130 through magnetic components 121, wherein multiple first snap-fit ​​portions 111 of each first keel member 110 are respectively snapped and fixed to multiple second keel members 120.

[0046] In summary, the first keel member 110 of the wall keel structure 100 is installed on the wall 200. The gap 131 between the first keel member 110 and the decorative sheet 130 facilitates wiring installation and gas circulation. The second keel member 120 can be connected to the first keel member 110 to form a snap-fit ​​structure, which fixes and limits the second keel member 120 and the first keel member 110 to each other, making installation more convenient and improving installation efficiency. The staggered arrangement of the second keel member 120 and the first keel member 110 can distribute the load and reduce local stress concentration, making the connection between the second keel member 120 and the first keel member 110 more stable and improving space utilization. The decorative sheet 130 and the second keel member 120 are magnetically connected by a magnetic member 121. The magnetic member 121 provides a fixed support point to facilitate the installation and connection of the decorative sheet 130, making the installation and replacement of the decorative sheet 130 more convenient.

[0047] refer to Figures 1 to 3 As shown, an embodiment of this application provides another wall keel structure 100, which includes a plurality of first keel members 110, a plurality of second keel members 120, a magnetic member 121, and a plurality of decorative sheets 130. The plurality of first keel members 110 are all installed on the wall 200. Each of the second keel members 120 is engaged with the side of the first keel member 110 away from the wall 200 to form a snap-fit ​​structure. The second keel member 120 and the first keel member 110 are staggered. The first keel member 110 is installed on the wall 200. The gap 131 between the first keel member 110 and the decorative sheet 130 facilitates wiring installation and air circulation. The second keel member 120 can be connected with the first keel member 110 to form a snap-fit ​​structure, so that the second keel member 120 and the first keel member 110 are fixed and limited to each other, making installation more convenient and improving installation efficiency. The staggered arrangement of the second keel member 120 and the first keel member 110 can distribute the load, reduce local stress concentration, make the connection between the second keel member 120 and the first keel member 110 more stable, and improve space utilization. A magnetic component 121 is disposed on the side of the second keel component 120 opposite to the first keel component 110. Each of the decorative sheets 130 is magnetically connected to the second keel component 120 via the magnetic component 121. The second keel component 120 is located between the first keel component 110 and the decorative sheet 130, and a gap 131 exists between the first keel component 110 and the decorative sheet 130. Correspondingly, the decorative sheet 130 and the second keel component 120 are magnetically connected via the magnetic component 121. The magnetic component 121 provides a fixed support point to facilitate the installation and connection of the decorative sheet 130, making the installation and replacement of the decorative sheet 130 more convenient.

[0048] In one embodiment, alternatively, referencing Figure 2 and Figure 3As shown, a first keel member 110 is provided with a plurality of first snap-fit ​​parts 111, which are arranged along the first direction X, that is, the plurality of first snap-fit ​​parts 111 are arranged along the length direction of the wall keel structure 100, so that the plurality of first snap-fit ​​parts 111 are used to connect and fix the second keel member 120, thereby improving the connection stability between the first keel member 110 and the second keel member 120.

[0049] Optionally, such as Figure 3 and Figure 4 As shown, the second keel member 120 is provided with a first slot 122. Two adjacent first engaging parts 111 are engaged into one first slot 122, and the first engaging parts 111 are engaged with the side wall of the first slot 122. Correspondingly, one first slot 122 corresponds to two first engaging parts 111, so that the two first engaging parts 111 are engaged with the side wall of the first slot 122 respectively, thereby engaging the first keel member 110 and the second keel member 120. Of course, the first engaging parts 111 can be separated from the first slot 122, realizing the separation between the first keel member 110 and the second keel member 120. Exemplarily, the first engaging part 111 is provided with a mounting hole, through which the first engaging part 111 can be connected and fixed.

[0050] Furthermore, the second keel member 120 is also provided with a second snap-fit ​​part 1221, each second snap-fit ​​part 1221 snaps into a first snap-fit ​​part 111, so as to connect and fix the first keel member 110 and the second keel member 120, thereby further improving the stability of the keel structure.

[0051] Optionally, refer to Figure 3 and Figure 4 As shown, there are multiple first keel members 110, which are spaced apart along the second direction Y. The second direction Y is perpendicular to the first direction X, so that the first slot 122 of one second keel member 120 can correspond to multiple first keel members 110. In other words, the first keel members 110 are spaced apart along the height direction of the wall keel structure 100, so that the first slot 122 of the second keel member 120 can engage with multiple first keel members 110 at different heights, further improving the connection strength between the second keel member 120 and the first keel member 110.

[0052] In one embodiment, alternatively, referencing Figure 2 and Figure 3As shown, there are multiple second keel members 120, which are spaced apart along the first direction X, so that multiple first snap-fit ​​portions 111 of one first keel member 110 can correspond to multiple second keel members 120. That is, multiple second keel members 120 are spaced apart along the length of the wall keel structure 100, which reduces the temperature conduction effect, plays a certain role in heat preservation and prevents condensation, and avoids the decorative sheet 130 from becoming damp. The multiple second keel members 120 are magnetically connected to the decorative sheet 130 through magnetic members 121, wherein multiple first snap-fit ​​portions 111 of each first keel member 110 are respectively snapped and fixed to multiple second keel members 120. For example, the distance between adjacent second keel members 120 is D, which satisfies: 300mm≤D≤400mm.

[0053] In one embodiment, alternatively, referencing Figure 1 and Figure 5 As shown, the wall keel structure 100 also includes a first mounting component 140 and a second mounting component 150. The first mounting component 140 is provided with a first limiting part 1421, and the second mounting component 150 is provided with a second limiting part 1521. The two opposite ends of the decorative sheet 130 along the second direction Y are respectively engaged with the first limiting part 1421 and the second limiting part 1521. The first limiting part 1421 of the first mounting component 140 and the second limiting part 1521 of the second mounting component 150 respectively engage with the decorative sheet 130, thereby limiting and fixing the decorative sheet 130, preventing the decorative sheet 130 from tilting or slipping, and thus improving the structural stability of the wall keel structure 100.

[0054] Optionally, such as Figure 5 As shown, the first mounting component 140 includes a first fixing member 141 and a first mounting member 142. The first fixing member 141 abuts between the decorative sheet 130 and the ground 210. The first fixing member 141 is engaged with the first mounting member 142. The first mounting member 142 is provided with a first limiting part 1421 so that the decorative sheet 130 is located between the first limiting part 1421 and the second keel member 120. The first fixing member 141 is used to support and support the decorative sheet 130, so that the first limiting part 1421 and the second keel member 120 together fix and limit the decorative sheet 130. The first limiting part 1421 of the first mounting member 142 plays a limiting role on the decorative sheet 130 to prevent the decorative sheet 130 from tilting or slipping.

[0055] Optionally, such as Figure 2 and Figure 5As shown, the first fixing member 141 is provided with a second through groove 1411. The first fixing member 141 and the second keel member 120 are fixed through the bottom of the second through groove 1411.

Correspondingly, the second through groove 1411 of the first fixing member 141 facilitates the installation and fixing of the first fixing member 141 and the second keel member 120. Related components and wires can be installed in the second through groove 1411, which is conducive to wiring. The first mounting member 142 is used to close the opening of the second through groove 1411 and to conceal and cover the related wires, maintaining aesthetics.

[0056] For example, in combination Figure 5 and Figure 6 As shown, the second through groove 1411 has a third snap-fit ​​part at its opening, and the first mounting member 142 has a second slot. The third snap-fit ​​part snaps into the second slot, that is, the third snap-fit ​​part and the second slot form a snap-fit ​​structure, so that the first mounting member 142 and the first fixing member 141 are connected and fixed. The two are snapped together more firmly, preventing the first mounting member 142 from being misaligned under the pressure of the decorative sheet 130. Alternatively, the first mounting member 142 and the first fixing member 141 can be separated for the user to inspect and maintain.

[0057] In one embodiment, optionally, the second mounting assembly 150 includes a second fixing member 151 and a second mounting member 152.
