[0030] The present embodiment provides a finished plate, as shown in Figure 1 and Figure 2 The finished plate includes a panel assembly 1 and an anchoring assembly 2. The panel assembly 1 includes a first panel 11, an insulation layer 12 and a second panel 13 connected together, and the insulation layer 12 is located between the first panel 11 and the second panel 13. The anchoring assembly 2 includes a connecting rod 21, a first fastener 22 and a first connecting piece 23, the connecting rod 21 is arranged through the insulation layer 12 and the first panel 11 along the thickness direction of the panel assembly 1, one end of the connecting rod 21 is connected with the second panel 13 through the first connecting piece 23, and the other end of the connecting rod 21 is connected with the first fastener 22, so that the first fastener 22 abuts against one side of the first panel 11 away from the second panel 13.

[0031] The first panel 11, the insulation layer 12 and the second panel 13 are tightly connected into a stable whole by the anchoring assembly 2 on the basis of adhesion. This avoids the problems of poor weather resistance and the like existing in the finished plate only relying on the adhesion combination mode, enhances the structural strength, and enables the finished plate to maintain good integrity and stability during long-term use. Since the structural strength is guaranteed, when the finished plate is used as a protective layer of the outer wall of a building, it can effectively protect the internal structure from environmental factors such as sunlight, temperature, wind and rain, air pollution and the like, and when external forces such as wind load and earthquake force are borne, it can also ensure the stability of the wall and roof structure, and protect the safety of the building.

[0032] Specifically, the first panel 11 and the second panel 13 are made of calcium silicate board, and the insulation layer 12 is made of rock wool. The thickness of the first panel 11 is greater than that of the second panel 13, one side of the second panel 13 of the finished plate is connected with the wall, and one side of the first panel 11 serves as the outer surface of the building and is directly exposed to the external environment. The calcium silicate board has good fireproof, moistureproof and durability, and when used as the first panel 11, its thicker structure can better resist external impact and erosion, protecting the insulation layer 12 and the second panel 13, and the thickness of the thinner second panel 13 needs to meet the requirements of wall installation, and the rock wool insulation layer 12 has excellent heat insulation performance, which can reduce the heat exchange between the inside and outside of the building and reduce energy consumption.

[0033] It is worth noting that the selection of materials and the setting of thicknesses of the first panel 11, the second panel 13 and the insulation layer 12 need to be determined according to actual requirements, and are not specifically limited here.

[0034] In the embodiment, as shown in Figure 1 and Figure 2 , the first panel 11 is provided with a first mounting hole 111, the first fastener 22 is T-shaped, and the first fastener 22 includes a head 221 in a cylindrical or hemispherical shape and a rod 222 in a ring shape, the diameter of the head 221 is larger than that of the rod 222, the rod 222 penetrates the first mounting hole 111 and is connected with the connecting rod 21, and the head 221 abuts against the side of the first panel 11 away from the second panel 13. This can prevent the first fastener 22 from being pulled out of the first mounting hole 111, and make the anchoring assembly 2 more stable in connection with the first panel 11. Moreover, the head 221 increases the contact area with the first panel 11, disperses the pressure, reduces the damage to the first panel 11, and protects the surface quality thereof.

[0035] In some embodiments, the first mounting hole 111 can be a through hole, in which case the head 221 of the first fastener 22 needs to abut against the surface of the side of the first panel 11 away from the second panel 13. In order to avoid the head 221 of the first fastener 22 protruding from the surface of the first panel 11 and affecting the aesthetic appearance, the thickness of the head 221 of the first fastener 22 is preferably as small as possible, and the surface of the head 221 can be arc-shaped to better fit the surface of the first panel 11.

[0036] In the embodiment, the first mounting hole 111 is a countersunk hole, and the head 221 is completely immersed in the countersunk hole, so that the surface of the side of the first panel 11 away from the second panel 13 is flat without protrusions. When the finished panel is used for the protection of the outer wall of a building, this can improve the overall aesthetic appearance and avoid the head 221 of the first fastener 22 being exposed to damage the architectural appearance coordination. At the same time, the countersunk hole provides a space for the head 221, which can protect the head 221 from being eroded by rain, dust, etc., and prevent external objects from colliding with the head 221, thereby ensuring the stability of the connection between the first fastener 22 and the first panel 11 and avoiding the loosening of the connection due to external interference.

[0037] In the embodiment, as shown in Figure 2 , a second mounting hole 121 is provided on the thermal insulation layer 12 at a position corresponding to the first mounting hole 111. The connecting rod 21 penetrates the second mounting hole 121, so that the thermal insulation layer 12 abuts against the first panel 11. As shown in Figure 1As shown, the connecting rod 21 includes a rod body 211. A first connecting portion 212 is protruded from one end of the rod body 211 near the first panel 11. The first connecting portion 212 is provided with an external thread and cooperates with the internal thread of the first fastener 22. The connecting rod 21 and the first fastener 22 are connected by a threaded connection method, which ensures a secure connection between the two. When the finished panel is subjected to external forces such as vibration and tension, the first fastener 22 can be prevented from loosening from the connecting rod 21, thereby ensuring the connection reliability of the anchor assembly 2 and maintaining the stability of the entire finished panel structure. At the same time, the threaded connection facilitates installation. Construction workers can rotate the connecting rod 21 to install it with the first fastener 22, thereby achieving abutment and fixation of the first panel 11. When repairing or replacing the finished panel, the first fastener 22 can also be easily removed, which helps improve construction efficiency and the convenience of subsequent maintenance.

[0038] In this embodiment, if Figure 1 As shown, the anchor assembly 2 also includes a second connector 25, which is sleeved onto the first connecting portion 212 and abuts the side of the first panel 11 facing the second panel 13. The second connector 25 provides additional support for the connection between the anchor assembly 2 and the first panel 11, further enhancing the stability of the overall connection, making the first panel 11 less susceptible to displacement when subjected to force, and improving the structural reliability of the finished panel under complex load conditions. Specifically, the second connector 25 has internal threads that mate with the external threads of the first connecting portion 212, enhancing the stability of the connection between the second connector 25 and the connecting rod 21.

[0039] In this embodiment, if Figure 1 As shown, along the thickness direction of the finished board, the sum of the dimensions of the rod body 211, the first connector 23 and the second connector 25 is equal to the dimension of the insulation layer 12. This effectively avoids the situation where the first connector 23 and the second connector 25 protrude from the insulation layer 12, ensuring the flatness of the outer surface of the insulation layer 12. When assembled with the first panel 11 or the second panel 13, the insulation layer 12 will not be squeezed due to the protrusion of the first connector 23 and the second connector 25, thereby avoiding affecting the surface flatness of the first panel 11 and the second panel 13. In other embodiments, along the thickness direction of the finished board, the sum of the dimensions of the rod body 211, the first connector 23 and the second connector 25 is greater than the dimension of the insulation layer 12. In this case, a receiving groove (not shown) can be opened on the side close to the first panel 11 and the second panel 13 to accommodate the portion that exceeds the insulation layer 12, thereby ensuring the surface flatness of the first panel 11 and the second panel 13.

[0040] In this embodiment, if Figure 1As shown, the second end of the rod body 211 close to the second panel 13 is provided with a second connecting part 213, which is provided with external threads and cooperates with the internal threads of the first connecting part 23, so as to prevent the connecting rod 21 from loosening or separating from the first connecting part 23 and to enhance the stability of the connection of the anchoring assembly 2.

[0041] As shown in the drawings, Figure 1 The anchoring assembly 2 further comprises a second fastener 24, which is connected to the first connecting part 23 through the second panel 13. This makes the connection between the anchoring assembly 2 and the second panel 13 more stable. Through this connection, the possibility of the anchoring assembly 2 moving or separating from the second panel 13 is reduced, thereby improving the stability of the entire anchoring assembly 2 in the finished panel and ensuring the integrity of the structure of the finished panel.

[0042] Specifically, as shown in the drawings, Figure 1 and Figure 2 The second fastener 24 is a self-tapping screw, and the second panel 13 is provided with a third mounting hole 131, and the second fastener 24 is connected to the first connecting part 23 through the third mounting hole 131. Alternatively, the third mounting hole 131 can be a countersunk hole, and when the second fastener 24 is a countersunk self-tapping screw, the head of the second fastener 24 can be sunk into the countersunk hole, so that the surface of the second panel 13 is flat, avoiding the influence on the appearance or causing the collision with other objects.

[0043] Alternatively, in some embodiments, the third mounting hole 131 can also be a straight-through hole, which can meet the basic connection function, and at this time, the head of the second fastener 24 protrudes from the surface of the second panel 13. When the second panel 13 is connected to the wall and adhesive (not shown in the figure) is applied between the two, the adhesive can be self-adapted to fill according to the surface morphology of the wall and the second panel 13 during the application and curing process, so that the protruding part of the second fastener 24 is sunk therein, thereby ensuring the stability and reliability of the connection structure of the second panel 13 and the wall. In addition, the second panel 13 can also not be provided with the third mounting hole 131, and at this time, the second fastener 24 can be directly screwed into the second panel 13, so that the second fastener 24 is flush with the outer surface of the second panel 13.

[0044] It is worth noting that the second fastener 24 can also be a screw, a pin, etc., as long as it can meet the requirement of fixing the second panel 13 and the first connecting part 23, and specific limitations are not made here.

[0045] Further, at least two second fasteners 24 are arranged on the first connecting member 23 in a spaced ring penetrating the second panel 13. The plurality of second fasteners 24 are arranged in a spaced ring, which can make the force between the anchoring assembly 2 and the second panel 13 more uniform, so that the second panel 13 can bear external force more stably. In addition, the connection from different angles and positions can enhance the connection firmness of the anchoring assembly 2 and the second panel 13, and reduce the possibility of loose connection. In the embodiment, as shown in Figure 1 FIG. 6, there are two second fasteners 24 arranged on the first connecting member 23 in a spaced ring penetrating the second panel 13. In other embodiments, three, four or other number of second fasteners 24 can be arranged on the first connecting member 23 in a spaced ring penetrating the second panel 13.

[0046] In the embodiment, as shown in Figure 1 FIG. 6, the diameter of the first connecting member 23 is larger than the diameter of the connecting rod 21, which facilitates the installation of the second fastener 24 and avoids the installation position of the second fastener 24 interfering with the connecting rod 21. In this way, the connecting rod 21 will not be collided or scraped when the second fastener 24 is installed, thereby protecting the surface quality and structural integrity of the connecting rod 21.

[0047] In the embodiment, the diameter of the second connecting member 25 is smaller than the diameter of the rod body 211. This facilitates the processing of the second installation hole 121 on the thermal insulation layer 12, reduces the processing difficulty, and is conducive to reducing the damage to the thermal insulation layer 12, reducing the cutting area of the thermal insulation layer 12, and helping to maintain the thermal insulation performance and structural integrity of the thermal insulation layer 12.

[0048] That is, the diameters of the first connecting member 23, the connecting rod 21 and the second connecting member 25 are gradually reduced, which can facilitate the assembly by sequentially installing the second connecting member 25, the connecting rod 21 and the first connecting member 23 into the second installation hole 121 from one direction.

[0049] In the embodiment, the finished panel includes a plurality of anchoring assemblies 2 arranged in order and spaced on the panel assembly 1. Here, the number of anchoring assemblies 2 is not specifically limited, and the number is mainly determined according to the size of the finished panel, the stress condition of the use environment and the requirement for structural stability.

[0050] The assembly process of the finished panel of the embodiment is as follows:

[0051] First step: a plurality of first installation holes 111 are arranged on the first panel 11 in a spaced manner. Then, the first fastener 22 is placed in the first installation hole 111, so that the second connecting member 25 abuts against one side of the first panel 11 facing the thermal insulation layer 12. Subsequently, the connecting rod 21 is sequentially penetrated through the second connecting member 25 and the first installation hole 111, and connected with the first fastener 22 to ensure firm connection.

[0052] Second step: a second mounting hole 121 is opened on the thermal insulation layer 12 at a position corresponding to the first mounting hole 111. Then, the connecting rod 21 is passed through the second mounting hole 121, so that the thermal insulation layer 12 abuts against the first panel 11. In this process, an appropriate amount of glue is applied between the thermal insulation layer 12 and the first panel 11 to enhance the connecting effect of the two. Finally, the first connecting piece 23 is connected with the connecting rod 21 to ensure the stability of the connection.

[0053] Third step: a third mounting hole 131 is opened on the second panel 13, the second panel 13 is abutted against the thermal insulation layer 12, and an appropriate amount of glue is applied between the second panel 13 and the thermal insulation layer 12. Then, the second fastener 24 is passed through the second panel 13 and connected with the first connecting piece 23. In order to make the connection more stable, at least two second fasteners 24 are passed through the second panel 13 and spaced around the first connecting piece 23.

[0054] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application.
