[0048] To facilitate the understanding of the above technical solutions of the present invention, the above technical solutions of the present invention will be described in detail below through specific usage modes.

[0049] In specific use, for a wall panel prefabricated installation structure for the external corner of a wall according to the present invention, its product combination state usage mode is as Figure 1-2 shown; the wall panel includes a panel layer 1, a support layer 2, and a closed layer 3. The core components of the installation prefabricated installation structure include a connecting member 4 and a rotary leveling member 11. Other accessories also include an upper sealing strip 16, a lower sealing strip 17, a fixed corner code, and a support adjustment component that can be selected according to the usage scenario, etc.

[0050] Among them, an outer sealing strip opening 5, a lower sealing strip opening 6, an insertion opening 7, a first corner code connection opening 8, a second corner code connection opening 9, and a strength strengthening cavity 10 are formed inside and on the connecting side of the connecting member 4.

[0051] The fixed edge of the wall panel is on one side of the limit stop 19 of the "L"-shaped limit structure that limits the wall panel above the connecting member 4 during factory production. The upper sealing strip opening 5 and the lower sealing strip opening 6 are used to cooperate with the linear upper sealing strip 16 and lower sealing strip 17 during installation to play a water blocking role and prevent water from seeping from the adjustment seam 15 of the panel layer 1 to the back side of the back panel of the closed layer 3;

[0052] As Figure 1-2 shown, the insertion opening 7 on the connecting member 4 is a side "T"-shaped insertion opening with a large belly and a small mouth, which is used to be snap-connected to the snap connection part 14 on the rotary leveling member 11, so as to play a role of connection and limit. As Figure 4-6The rotation leveling part 11 shown rotates. A special thin wrench is used to rotate the pre-inserted rotation leveling part 11 by 90 degrees from the adjustment gap 15 between the wall panels, so that the clamping part 14 plays a role of fixed clamping. The cross-section of the strength reinforcement cavity 10 above the insertion opening 7 is a right triangle, which further improves the firmness of the entire connecting part and the stability of the connection.

[0053] The connection method of the entire wall panel system is as follows: The first installed wall panel and the connecting part 4 are fixedly connected through the above-mentioned connecting structure of an assembled integral bathroom wall panel. Then, after the rotation leveling part 11 is pre-installed into the insertion opening 7 of the connecting part 4, one end of the fixed angle code is fixed on the original structural wall through the fixed angle code, and the other end of the fixed angle code is inserted into the groove of the first angle code connection port 8 or the second angle code connection port 9, so as to achieve the purpose of convenient subsequent disassembly. Finally, the wall panel on the other side of the external corner is butted against the pre-installed wall panel above. After the butting and the leveling of the flush height are completed, optionally, the clamping part 14 on the rotation leveling part 11 can be rotated by 90 degrees with a wrench to complete the assembled installation of a group of adjacent external corner wall panels. The subsequent wall panels to be installed can be installed in the above manner in sequence to complete the assembled installation of the wall panels at the external corners of the entire wall. In another embodiment, the plug-in leveling part 21 can also be selected to replace the above-mentioned rotation leveling part 11. The plug-in leveling part 21 is first fixed in the insertion opening 7 of the connecting part 4 on one side, and then is connected to the insertion opening 7 of the adjacent connecting part 4 by direct plug-in connection.

[0054] In some projects where the ground needs to be elevated, it can be used in cooperation with the support adjustment component. Through holes are provided at the bottom of the connection of the connecting part 4 for fixing bolts. The bolts are fixed to the first wall panel board by nailing. After leveling, optionally, a one-component polyurethane foam adhesive is injected into the bolts and adhered to the ground, which can not only not damage the waterproofing but also avoid the problem of screw back-off. Subsequently, the second board can be placed on the support plate of the screw to complete the installation.

[0055] In summary, by means of the above technical solutions of the present invention, through the detachable connection method of the connecting part and the rotation leveling part, the assembled installation of the board is effectively realized, thereby meeting the requirements of reducing the construction professionalism of the operators. It can be disassembled reversely and recycled, avoiding the waste of building materials, improving the accuracy requirements of the external corner angle, and overall shortening the construction period and improving the construction quality.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
