[0042] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other arbitrarily.

[0043] Please refer to Figures 1 to 12, a prefabricated wall system, comprising a plurality of wall panel components 1, a plurality of external corner components 2 and a plurality of internal corner components 3, wherein any two components can be connected to each other pairwise. The wall panel component 1 includes a main keel 12 and wall panels 11 fixedly arranged on the main keel 12. The wall panel components 1 are independent of each other, and adjacent two wall panel components 1 are leveled, positioned and connected through a flat joint 4. During assembly, first, the internal assembly of each component is carried out, and then the assembly between components is carried out in a clockwise or counterclockwise order around the room. The components are leveled and positioned through structures such as the flat joint 4, which can effectively improve the flatness of the installed wall and the installation efficiency.

[0044] Please refer to Figure 2 and Figure 9 , the wall panel component 1 includes a main keel 12, wall panels 11 and auxiliary keels 13. Limiting grooves 111 are arranged on both sides of the back end face of the wall panel 11, and the limiting grooves 111 extend along the length direction of the wall panel 11; the auxiliary keel 13 is used to connect two adjacent wall panels 11 within the same wall panel component 1. The end face of the auxiliary keel 13 is a flat surface so as to fit with the back end face of the wall panel 11. After the wall panel 11 is connected to the auxiliary keel 13, the end faces of two adjacent wall panels 11 can be kept coplanar, ensuring the overall flatness of the wall panel component 1. Limiting insertion plates 131 are arranged at both ends of the auxiliary keel 13; within the same wall panel component 1, when two adjacent wall panels 11 are connected, the limiting insertion plates 131 on the auxiliary keel 13 can be inserted into the limiting grooves 111 of the two wall panels 11 at the same time to preliminarily position the two wall panels 11, and then the auxiliary keel 13 is fixedly connected to the two wall panels 11 through screws. When fixing, the positions of the screws should meet the requirement that screws are arranged at the connection positions of the auxiliary keel 13 and the two wall panels 11, as Figure 9 shown.

[0045] The main keel 12 is horizontally placed on the back of the wall panel 11 to increase the strength of the wall panel component 1. Within one wall panel component 1, the main keel 12 straddles all the wall panels 11 and is fixedly connected to all the wall panels 11 and the auxiliary keels 13. In actual use, the width of the wall panel component 1 depends on the number of the wall panels 11. The number of the wall panels 11 should be adjusted according to the actual measurement data, and the main keel 12 should be cut accordingly; in order to avoid unevenness at the connection due to the extension of the main keel 12, within one wall panel component 1, only one main keel 12 is arranged in the width direction of the wall panel 11, that is, the maximum width of the wall panel component 1 depends on the length of the main keel 12. And, in order to ensure the overall strength of the wall panel component 1, a plurality of main keels 12 should be evenly spaced in the height direction of the wall panel 11. As in this embodiment, three main keels 12 are arranged in the length direction of the wall panel component 1 to reinforce the wall panel component 1.

[0046] Preferably, a sealing groove is further provided on the side end face of the wall panel 11. Within the same wall panel assembly 1, the side end faces of two adjacent wall panels 11 are close to each other, and the sealing grooves thereon form a channel for accommodating the sealing strip 14 relatively. The sealing strip 14 is arranged in this channel. When installing the bathroom wall, the sealing strip 14 can be used to isolate water vapor and prevent components such as the main keel 12, the secondary keel 13, and the screws from getting damp.

[0047] Within the same wall panel assembly 1, a hanging buckle 5 is provided on the outermost side wall panel 11 of the wall panel assembly 1 for cooperating with the flat joint 4 to connect another wall panel assembly 1, or the external corner assembly 2, or to connect the internal corner piece 3.

[0048] Please refer to Figure 3 , the external corner assembly 2 includes an external corner wall panel 21 and a reinforcement plate 22. The external corner wall panel 21 is integrally formed to form an external corner angle 211. Since the external corner wall panel 21 is a single whole board, to increase the structural strength at the external corner angle 211, a reinforcement plate 22 is provided at the external corner angle 211. The reinforcement plate 22 is a bent structure, and its bending angle is the same as the angle of the external corner angle 211. The folded corner of the reinforcement plate 22 fits the external corner angle 211, and both sides of the folded corner of the reinforcement plate 22 are attached to the external corner wall panel 21. The reinforcement plate 22 and the external corner wall panel 21 are fixedly connected by screws, and the screw fixing positions should meet the requirement that screws are provided on both sides of the external corner angle 211.

[0049] In this embodiment, the external corner angle 211 is a right angle, and the external corner wall panel 21 is a stone plastic board. A common stone plastic board has a double-layer structure, with two layers of board surfaces spaced apart, and a connecting plate is provided between the two layers of board surfaces to improve the stiffness of the stone plastic board. Since the external corner wall panel 21 is arranged at the external corner, its external corner angle 211 is relatively prominent and is easily collided. To further increase the structural strength at the external corner angle 211 of the external corner wall panel 21, support squares 23 are further provided inside the external corner wall panel 21. The two support squares 23 are arranged on both sides of the external corner angle 211 to increase the structural strength on both sides of the external corner angle 211.

[0050] A hanging buckle 5 is provided on the side of the external corner wall panel 21 for cooperating with the flat joint 4 to connect another external corner piece, or the wall panel assembly 1, or to connect the internal corner piece 3.

[0051] Please refer to Figure 6 and Figure 7, the flat joint piece 4 is used to connect two adjacent wall panel components 1 or to connect the wall panel component 1 and the external corner component 2, and includes a connected connecting portion 41 and a positioning portion 42. The end faces of the connecting portion 41 and the positioning portion 42 are coplanar and are respectively used to connect the two wall panel components 1. The coplanar end faces of the connecting portion 41 and the positioning portion 42 are both flat straight faces, so that when connecting the two wall panel components 1, the connection is based on this end face, thereby ensuring the plane unity of the two wall panel components 1 and embodying the flatness of the overall wall surface system. A positioning groove 43 is provided on the positioning portion 42. The positioning groove 43 includes a connected guiding opening 431 and a limiting opening 432. The diameter of the guiding opening 431 is larger than that of the limiting opening 432 to facilitate the hanging buckle 5 to enter into the limiting opening 432, and there is an included angle between the guiding opening 431 and the limiting opening 432, so that the positioning groove 43 has a bend, and it is not easy for the hanging buckle 5 to escape after entering the limiting opening 432 through the guiding opening 431.

[0052] In this embodiment, both the positioning portion 42 and the connecting portion 41 are plate members. The positioning groove 43 is arranged through the thickness direction of the positioning portion 42. The guiding opening 431 extends from the side end of the positioning portion 42 towards the middle thereof, and the limiting opening 432 is located obliquely below the guiding opening 431. The connecting portion 41 is fixedly connected to the wall panel at the end of the wall panel component 1 by screws. When connecting another wall panel component 1, move another wall panel component 1 to make the hanging buckle 5 on another wall panel component 1 enter into the limiting opening 432 along the guiding opening 431 for preliminary positioning connection, and then perform fine adjustment, and fix another wall panel 11 and the flat joint piece 4 by screws.

[0053] Preferably, at least two positioning grooves 43 are provided to play an effective positioning role. The positioning grooves 43 are arranged at straight-line intervals along the length direction of the flat joint piece 4 for easy processing.

[0054] Furthermore, since the positioning groove 43 is opened on the positioning portion 42, to increase the structural strength of the positioning portion 42 and avoid bending of the positioning portion 42, the thickness of the positioning portion 42 is greater than the thickness of the connecting portion 41.

[0055] Furthermore, a connecting plug plate 411 is provided at the side end of the connecting portion 41. The connection of the flat joint piece 4 can be realized by inserting the connecting plug plate 411 into the limiting groove 111 on the wall panel 11 for quick positioning. Correspondingly, to facilitate the quick positioning of the flat joint piece 4 and the external corner component 2, a notch (not shown in the figure) with the same size and specification as the limiting groove 111 is provided on the side of the external corner wall panel 21, and the connecting plug plate 411 can be quickly positioned with the external corner wall panel 21 through this notch.

[0056] Please refer to Figure 8, the hanging buckle 5 includes a coaxial stop plate 51 and a connecting short rod 52 connected to each other. The maximum radial dimension of the connecting short rod 52 is smaller than the minimum radial dimension of the limiting opening 432, and the minimum radial dimension of the stop plate is larger than the maximum radial dimension of the limiting opening 432. The hanging buckle 5 enters the limiting opening 432 along the guiding opening 431 through the connecting short rod 52, and the stop plate 51 forms a stop in front of the limiting opening 432 to prevent the hanging buckle 5 from moving forward and backward and disengaging. The limiting opening 432 is located obliquely below the guiding opening 431, and the positioning groove 43 as a whole has a bend to prevent the hanging buckle 5 from moving out unidirectionally.

[0057] Further, a fixing hole 511 is provided on the hanging buckle 5. The fixing hole 511 is coaxially arranged with the stop plate 51 and penetrates through the stop plate 51 and the connecting short rod 52. In this embodiment, the fixing hole 511 is a threaded hole, and the hanging buckle 5 can be fixed to the wall panel 11 or the corner wall panel 21 by cooperating with the fixing hole 511 with a screw.

[0058] The hanging buckle 5 is arranged on the wall panel 11 at the end of the wall panel assembly 1, and is set corresponding to the quantity and position of the positioning grooves 43 on the flat connecting piece 4.

[0059] Please refer to Figure 10 , when connecting two wall panel assemblies 1, first insert the connecting plug board 411 into the limiting groove 111 on the wall panel 11 at the outermost side of one of the wall panel assemblies 1 for positioning. After adjusting the wall panel 1 to be in contact with the end face of the connecting part 41, use screws to fixedly connect the connecting part 41 of the flat connecting piece 4 with the wall panel 1. Then move the other wall panel assembly 1 to make the hanging buckle 5 on the outermost side wall panel 11 of the other wall panel assembly 1 move into the positioning groove 43, so as to realize the hanging and positioning of the two wall panel assemblies 1. After moving and adjusting the other wall panel assembly 1 until the outermost side wall panel 11 thereof is in contact with the end face of the positioning part 42, use screws to fix the flat connecting piece 4 with the wall panel assembly 1, and thus the connection of the two wall panel assemblies 1 is completed.

[0060] When connecting the wall panel assembly 1 with the corner component 2, the same as connecting two wall panel assemblies 1, first insert the connecting plug board 411 into the limiting groove 111 on the outermost side wall panel 11 of the wall panel assembly 1 for positioning. After adjusting the wall panel 1 to be in contact with the end face of the connecting part 41, use screws to fixedly connect the connecting part 41 of the flat connecting piece 4 with the wall panel 1. Then move the corner component 2 to make the hanging buckle 5 on the side of the corner wall panel 21 be hung and positioned with the positioning groove 43. Then move the corner component 2 for adjustment until the corner wall panel 21 is in contact with the end face of the positioning part 42, and use screws to fix the flat connecting piece 4 with the corner component 2, and thus the connection of the corner component 2 with the wall panel assembly 1 is completed. Similarly, when the flat connecting piece 4 is first fixed to the corner wall panel 21 and then the wall panel assembly 1 is connected, the same connection steps are adopted.

[0061] Please refer to Figure 4 and Figure 5, the internal corner member 3 includes two side plates 31 that intersect to form an internal corner, and a support member 32 is provided at the included angle thereof to improve the connection strength of the two side plates 31 and provide positioning when the internal corner member 3 is connected to the wall panel 11. In this embodiment, the internal corner member 3 forms a right angle, the support member 32 is a square-shaped hollow structure, and the right-angle ends of the support member 32 are arranged corresponding to the included angle of the internal corner member 3. An internal corner positioning groove 311 is provided on one of the side plates 31 for hanging and positioning with the hanging buckle 5 when connecting the wall panel assembly 1 or the external corner assembly 2. For the convenience of the same processing, the internal corner positioning groove 311 and the positioning groove 43 have the same size specifications and the same number.

[0062] When connecting the two wall panel assemblies 1, first move the wall panel of one wall panel assembly 1 along the side plate 31 until the wall panel 11 abuts against the outer wall of the support member 32 and then fix it with bolts. Then move the other wall panel assembly 1 so that the hanging buckle 5 on the wall panel assembly 1 is hung and connected with the internal corner positioning groove 311. Adjust the other wall panel assembly 1 so that it fits with the side plate 31 and then fix the side plate 31 and the wall panel assembly 1 with screws, and the connection between the internal corner member 3 and the two wall panel assemblies 1 can be completed.

[0063] The steps for connecting the two external corner assemblies 2 or connecting the external corner assembly 2 and the wall panel assembly 1 are the same as above.
