The internal corner stop plates 312 may be L-shaped plates. One ends of the two internal corner stop plates 312 are respectively connected to the two side ends of the second base plate 311. The two internal corner stop plates 312 are arranged oppositely, and a second insertion through hole 313 is formed between the other ends of the two internal corner stop plates 312. By observation, align the seventh installation through hole with the second insertion through hole 313, so that the first internal corner connecting plate 321 is parallel to the second base plate 311. The first internal corner connecting plate 321 abuts against the internal corner stop plates 312, then the internal corner stop plates 312 support the first internal corner connecting plate 321. One end of the fourth fastening structure 325 passes through the seventh installation through hole and the third insertion through hole in sequence and is fixedly connected to the second base plate 311, thereby tightly connecting the first internal corner connecting plate 321 and the second base plate 311. The two internal corner stop plates 312 can limit the connection of the fourth fastening structure 325 to the second base plate 311. By aligning the seventh installation through hole with the second insertion through hole 313, it is convenient to align the seventh installation through hole with the preset position on the second base plate 311. A strip-shaped eighth installation through hole 314 may be provided on the second base plate 311. The second telescopic member 33 includes a third expansion tube, a second lead screw, and a second fastening nut. The third expansion tube is fixedly connected to the wall surface. A third internal thread is provided inside the third expansion tube. The second lead screw includes a second stud and a second limiting block connected to one end of the second stud. One end of the second stud passes through the eighth installation through hole 314 and is screwed to the third internal thread. The second fastening nut is screwed to a part of the second stud on the side of the second base plate 311 when the second limiting block abuts against the second base plate 311.

[0058] Specifically, the eighth installation through hole 314 is strip-shaped, which facilitates connecting the second telescopic member 33 to different positions on the second substrate 311 and different positions on the wall surface. It may also include a second gasket for fixedly connecting the third expansion tube to the wall surface. One end of the second stud passes through the eighth installation through hole 314 in sequence and is screwed into the second internal thread, and the length of the second stud extending into the third internal thread is adjusted, thereby adjusting the overall length of the second telescopic member 33, and further adjusting the distance between the second substrate 311 and the wall surface. Furthermore, the distance between the first internal corner connecting plate 321 and the wall surface and the distance between the third internal corner connecting plate 324 and the wall surface are adjusted, which facilitates snapping the third internal corner connecting plate 324 onto the connection slot 111 on the wall panel 11 in the first wall leveling component 1 at a preset distance from the wall surface. The second gasket is sleeved on the part of the second stud between the second limiting block and the second substrate 311, the second gasket abuts against the second substrate 311, the second limiting block abuts against the second gasket, and the second fastening nut is screwed onto the part of the second stud on one side of the second substrate 311 to complete the installation.

[0059] The internal corner member 32 may further include an internal corner support plate 326 for limiting the wall panel 11 when the third internal corner connecting plate 324 is snapped into the connection slot 111. The internal corner support plate 326 is connected to the part of the second internal corner connecting plate 323 between the first internal corner connecting plate 321 and the third internal corner connecting plate 324.

[0060] Specifically, after the third inner-corner connecting plate 324 is clamped into the connecting card slot 111 on the wall panel 11, if an external force impacts the wall panel 11 and the wall panel 11 moves towards the direction close to the wall surface, the wall panel 11 drives the third inner-corner connecting plate 324 to move towards the direction close to the wall surface, which easily breaks the third inner-corner connecting plate 324, resulting in unstable connection between the inner-corner member 32 and the wall panel 11. Connect the inner-corner support plate 326 to the part of the second inner-corner connecting plate 323 located between the first inner-corner connecting plate 321 and the third inner-corner connecting plate 324. When the third inner-corner connecting plate 324 is clamped into the connecting card slot 111, the inner-corner support plate 326 can abut against the wall panel 11. The inner-corner support plate 326 can limit the position of the wall panel 11. At the same time, when an external force impacts the wall panel 11 and the wall panel 11 moves towards the direction close to the wall surface, the inner-corner support plate 326 can dampen the vibration of the wall panel 11, reduce the force on the wall panel 11, protect the wall panel 11, and improve the connection stability between the wall panel 11 and the inner-corner member 32. The inner-corner member 32 can be in a zigzag structure. The first inner-corner connecting plate 321 and the third inner-corner connecting plate 324 are respectively arranged on different sides of the second inner-corner connecting plate 323. The inner-corner support plate 326 and the third inner-corner connecting plate 324 are arranged on the same side of the second inner-corner connecting plate 323. The first inner-corner connecting plate 321 can be vertically connected to the second inner-corner connecting plate 323, and the third inner-corner connecting plate 324 can be vertically connected to the second inner-corner connecting plate 323. Since the wall panel 11 in the first wall leveling component 1 and the wall panel 11 in the third wall leveling component 1 are respectively arranged on both sides of the second inner-corner connecting plate 323, it is necessary to arrange the first inner-corner connecting plate 321 and the third inner-corner connecting plate 324 on different sides of the second inner-corner connecting plate 323 respectively, which facilitates connecting the first inner-corner connecting plate 321 to the second support keel 31 and clamping the third inner-corner connecting plate 324 into the connecting card slot 111, and the installation is convenient.

[0061] Specifically, the internal corner member 32 may further include an internal corner protrusion for limiting the wall panel 11 when the connection card slot 111 moves towards the third internal corner connection plate 324. The internal corner protrusion is connected to the third internal corner connection plate 324. The third internal corner connection plate 324 is snap-fitted into the connection card slot 111 of the wall panel 11, and the internal corner protrusion limits the wall panel 11, making the surface of the internal corner member 32 and the wall panel 11 more flat and beautiful; the second internal corner connection plate 323 closes the opening of the wall panel 11 in the first wall leveling component 1, so that the wall panels 11 in the first wall leveling component 1 and the wall panels 11 in the third wall leveling component 1 form a concave-convex shape on the wall surface, increasing the beauty of the space and at the same time playing a role in connecting the relationship between the front and back levels. The internal corner support plate 326 may be provided with a third friction groove 327 for increasing the friction force. The third friction groove 327 and the wall panel 11 are used in cooperation to increase the friction force and reduce the sliding of the wall panel 11 during installation. The second telescopic member 33 may further include a second reinforcement pipe for increasing the strength of the second stud. The inner side of the second reinforcement pipe is provided with a fourth internal thread through which one end of the second stud sequentially passes through the eighth installation through hole 314, the seventh installation through hole, is screwed into the fourth internal thread, and is screwed into the third internal thread. The second reinforcement pipe may be a reinforced metal pipe.

[0062] The shapes of the second support keel 31 and the first support keel 12 may be the same, and the shapes of the second telescopic member 33 and the first telescopic member 15 may be the same.

The top of one side of the third wall leveling component 1 is connected to one side of the second wall leveling component 1, and the middle of one side of the third wall leveling component 1 is lapped on the other side of the internal corner installation component 3 close to the wall.

[0069] Specifically, horizontal and vertical lines are drawn on the wall surface to determine the installation positions of the sectional keels, and expansion tubes are installed by drilling holes at the positions. The keel clips are slid into the sectional keels from both left and right ends. They can be aligned according to the reserved hole positions and the positions of the keel clips can be adjusted by sliding left or right according to the actual situation on site. Then, the screw rod passes through the holes of the keel and the keel clip to reserve the hole positions for leveling and reinforcement. The back hangers 14 are installed at the positions of the decorative panels with screws, and then hung on the keel clips and fixed with bolts. The frog-shaped flat connectors are used to connect the horizontal decorative panels from left to right and fixed on the sectional keels with screws. At the convex turning points, the zigzag inside corner pieces 32 are inserted into the grooves of the decorative panels with screws and fixed on the sectional keels with screws.
