[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

As used in the specification and claims of the present application, the singular forms "a", "an", "the", "above", "said", "this" are also intended to include the forms such as "one or more", unless the context clearly indicates otherwise.

[0026] The reference to "one embodiment" or "some embodiments" etc. described in this specification means that a specific feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. appearing in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all of the embodiments", unless otherwise specifically emphasized in other ways. The terms "comprise", "include", "have" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0027] The decorative panel is connected to the wall by the back bolt method. The connection quality of the traditional back bolt method mostly depends on the skills and experience of workers. Moreover, when the decorative panel is a plate such as a fiber cement board, the connection effect of the traditional back bolt method is poor, and it is easy to cause the back bolts to become loose. When the decorative panel is a brittle plate such as a ceramic plate, the traditional back bolt connection is likely to cause the plate to break, posing a safety hazard.

[0028] To solve the above technical problems, the embodiments of the present application provide a decorative panel to improve the bearing effect of the built-in back groove type fixing connector of the decorative panel and reduce the damage to the decorative panel.

[0029] The decorative panel provided by the embodiments of the present application can be only used for decoration, or can be an integrated insulation and decoration board. The decorative panel can also have other functions besides insulation and decoration.

[0030] As shown Figures 1-4 in the figure, the decorative panel provided by the embodiment of the present application includes a decorative panel 1 and a built-in back groove type fixing connector (not marked in the figure). Among them, the built-in back groove type fixing connector is located on the wall side 10 of the decorative panel 1, and the built-in back groove type fixing connector is used to connect the decorative panel 1 and the wall.

[0031] The decorative panel 1 is provided with back bolt holes 2, and the back bolt holes 2 are filled with structural adhesive 3. And the built-in back groove type fixing connector is located in the back bolt holes 2. Among them, the structural adhesive 3 filled in the back bolt holes 2 can be epoxy structural adhesive, polyurethane structural adhesive, etc. The built-in back groove type fixing connector includes a screw 4 and an auxiliary fixing member 11. The auxiliary fixing member 11 is connected to one end of the screw 4, and both the auxiliary fixing member 11 and the screw 4 are fixed in the back bolt holes 2 through the structural adhesive 3. The auxiliary fixing member 11 can deform and be located in the back bolt holes 2 when the screw 4 is separated from the back bolt holes 2.

[0032] When the screw 4 is separated from the back bolt holes 2, the auxiliary fixing member 11 can deform. One end of the auxiliary fixing member 11 is connected to the screw 4, and the other end is still located in the back bolt holes 2 and adhered to the structural adhesive 3. In this way, the bearing capacity of the built-in back groove type fixing connector is increased, the connection strength between the built-in back groove type fixing connector and the decorative panel 1 is increased, and the brittle damage to the decorative panel 1 during the force application process of the built-in back groove type fixing connector is reduced, thereby reducing the damage to the decorative panel 1.

[0033] The screw 4 can be connected to the wall 10 through a wall connector. For the specific structure of the wall connector, it is selected according to the actual situation, and the embodiment of the present application does not limit this.

[0034] For the specific structure of the auxiliary fixing member 11, the following will be specifically described through two embodiments.

[0035] Embodiment 1

[0036] As shown Figure 1 and Figure 2 in the figure, in the first embodiment, the auxiliary fixing member 11 is a spring. The spring can be screwed into one end of the screw 4 along the thread direction on the screw 4, so that one end of the spring is threadedly connected to the screw 4, and the other end of the spring and the screw 4 are both located in the back bolt holes 2 and adhered to the structural adhesive 3 filled in the back bolt holes 2. When the screw 4 is separated from the back bolt holes 2, the spring is deformed by force. One end of the spring is still connected to the screw 4, and the other end of the spring is still located in the back bolt holes 2 under the bonding action of the structural adhesive 3. The spring can still provide a certain bearing capacity, thereby increasing the connection strength between the built-in back groove type fixing connector and the decorative panel 1.

[0037] The spring can be a cylindrical spring, or a tower spring, etc. In order to enhance the bonding strength between the spring and the structural adhesive 3, as shownFigure 1 As shown, the auxiliary fixing member 11 is a tower spring 5, and the small-diameter end of the tower spring 5 can be screwed into the screw 4 along the thread direction. The back bolt hole 2 is a tapered hole, the bottom diameter of the tapered hole is larger than the opening diameter of the tapered hole, and the large-diameter end of the tower spring 5 is located at the bottom of the tapered hole, increasing the contact area between the tower spring 5 and the structural adhesive, and further increasing the connection strength of the tower spring 5.

[0038] When the screw 4 is separated from the back bolt hole 2, as Figure 2 shown, at this time the tower spring 5 elongates, the small-diameter end of the tower spring 5 is connected to the screw 4, the large-diameter end of the tower spring 5 is still located in the back bolt hole 2 under the bonding action of the structural adhesive 3, and the tower spring 5 can provide a pulling force on the screw 4 after being stretched by force, so as to provide a certain bearing capacity for the decorative panel 1, thereby increasing the connection strength between the built-in back groove type fixing connector and the decorative panel 1, reducing the brittle damage to the decorative panel 1 during the force application process of the built-in back groove type fixing connector, and thus reducing the damage to the decorative panel 1.

[0039] When the decorative board in the first embodiment is used, first fill the back bolt hole 2 with the structural adhesive 3, screw the small-diameter end of the tower spring 5 into one end of the screw 4 and connect it with the screw 4 by thread, then put the large-diameter end of the tower spring 5 and the screw 4 into the back bolt hole 2 together, so that the large-diameter end of the tower spring 5 abuts against the bottom of the back bolt hole 2. At this time, the tower spring 5 is in its original length and does not provide elastic force. When the screw 4 is separated from the back bolt hole 2, the tower spring 5 elongates, the small-diameter end of the tower spring 5 is connected to the screw 4, the large-diameter end of the tower spring 5 is still located in the back bolt hole 2 under the bonding action of the structural adhesive 3, and the tower spring 5 can provide a pulling force on the screw 4 after being stretched by force, so as to provide a certain bearing capacity for the decorative panel 1, thereby increasing the connection strength between the built-in back groove type fixing connector and the decorative panel 1.

[0040] Embodiment Two

[0041] As Figure 3 and Figure 4 shown, in the second embodiment, the auxiliary fixing member 11 is a reinforcing rib 7. The reinforcing rib 7 includes one or more stainless steel wires, and different numbers of stainless steel wires can be selected according to actual situations. The reinforcing rib 7 is connected to one end of the screw 4, and the length direction of the reinforcing rib 7 has an included angle with the axial direction of the screw 4. In order to facilitate the auxiliary connection of the decorative panel 1 and the wall by the reinforcing rib 7, the back bolt hole 2 opened on the decorative panel 1 can place both the bolt 4 and the reinforcing rib 7 at the same time.

[0042] Exemplarily, as Figure 3As shown, the back bolt hole 2 includes a straight hole and a back groove 6. The back groove 6 passes through the straight hole along the radial direction of the straight hole. The width of the back groove 6 is adapted to the reinforcing rib 7 and is smaller than the diameter of the straight hole, so that the reinforcing rib 7 can just be placed in the back groove 6. And the reinforcing rib 7 includes at least two rib strips distributed in sequence along the circumferential direction of the screw rod 4. The back groove 6 is arranged in sequence along the circumferential direction of the straight hole and corresponds to the reinforcing rib 7 one by one. In this way, the back groove 6 corresponds to the reinforcing rib 7 one by one, limiting the circumferential movement of the reinforcing rib 7 along the screw rod 4, and further increasing the connection strength of the built-in back groove type fixing connector. For example, if the reinforcing rib 7 includes two rib strips, which are distributed in a roughly "one" shape along the circumferential direction of the screw rod 4, then the back groove 6 is a long strip and passes through the straight hole; or, if the reinforcing rib 7 includes four rib strips, which are distributed in a roughly "cross" shape along the circumferential direction of the screw rod 4, then the back groove 6 is a cross groove corresponding to the reinforcing rib 7. The specific number of the reinforcing ribs 7 in the embodiments of the present application is not limited.

[0043] In some other embodiments, the back bolt hole 2 is an elliptical hole, a square hole or other hole types that can simultaneously place the screw rod 4 and the reinforcing rib 7, so that the screw rod 4 connected with the reinforcing rib 7 can be directly placed in the back bolt hole 2, increasing the filling amount of the structural adhesive 3, further enhancing the connection strength of the reinforcing rib 7, saving the corresponding steps of the reinforcing rib 7 and the back groove 6, and improving the installation efficiency of the built-in back groove type fixing connector.

[0044] When the screw rod 4 is separated from the back bolt hole 2, as Figure 4 shown, at this time the reinforcing rib 7 is stressed and elongated. One end of the reinforcing rib 7 is connected to the screw rod 4, and the other end of the reinforcing rib 7 is still located in the back bolt hole 2 under the bonding action of the structural adhesive 3. The reinforcing rib 7 can provide a certain bearing capacity for the decorative panel 1, thereby increasing the connection strength between the built-in back groove type fixing connector and the decorative panel 1, reducing the brittle damage to the decorative panel 1 during the stress process of the built-in back groove type fixing connector, and thus reducing the damage to the decorative panel 1.

[0045] In some embodiments, the reinforcing rib 7 penetrates through one end of the screw rod 4. The reinforcing rib 7 can be one or more, respectively penetrating through the screw rod 4, further improving the connection strength of the reinforcing rib 7.

[0046] In some other embodiments, the reinforcing rib 7 is wound around the outer periphery of the screw rod 4. After the reinforcing rib 7 is wound, at least two rib strips are left distributed along the circumferential direction of the screw rod 4. Multiple reinforcing ribs 7 can also be wound. After multiple reinforcing ribs 7 are wound, four, six or more rib strips are left distributed along the circumferential direction of the screw rod 4, further improving the connection strength of the reinforcing rib 7.

[0047] When the decorative panel in the second embodiment is used, first, structural adhesives 3 are filled in both the straight holes of the back bolt holes 2 and the back grooves 6. One end of the screw rod 4 is penetrated by the reinforcing rib 7, and the rib strips at both ends of the reinforcing rib 7 penetrating the screw rod 4 are symmetrically distributed along the circumferential direction of the screw rod 4. Then, the screw rod 4 connected to the reinforcing rib 7 is placed in the back bolt hole 2 and is in full contact with the structural adhesive 3 in the back bolt hole 2. When the screw rod 4 is separated from the back bolt hole 2, the reinforcing rib 7 is stressed and elongated. One end of the reinforcing rib 7 is connected to the screw rod 4, and the other end of the reinforcing rib 7 is still located in the back bolt hole 2 under the bonding action of the structural adhesive 3. The reinforcing rib 7 can provide a certain bearing capacity for the decorative panel 1, thereby increasing the connection strength between the built-in back groove type fixing connector and the decorative panel 1.

[0048] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
