If chinese patent CN201621372252.8 discloses an assembled wallboard clamping structure, it is installed on the inner wall of the wall, including reentrant corner assembly section bar, hollow integrated wallboard, reentrant corner wall leveling member, plane wall leveling member and plane assembly section bar, reentrant corner wall leveling member is set up in wall corner department, reentrant corner wall leveling member both ends are connected with hollow integrated wallboard clamping respectively, be equipped with wall leveling member between reentrant corner wall leveling member and the wall, plane assembly section bar sets up in the wall inboard, plane assembly section bar both ends are connected with hollow integrated wallboard clamping respectively, be equipped with plane wall leveling member between plane assembly section bar and the wall. In the patent, clamping grooves are formed in two sides of a hollow integrated wallboard, and two adjacent hollow integrated wallboards are integrally assembled through plane assembly profiles (namely metal lines) in a clamping mode. For another example, chinese patent CN201910483729.1 discloses a wall panel mounting structure and a mounting method thereof. Wallboard mounting structure includes wallboard, joint spare and connecting piece, links to each other through the connecting piece between two adjacent wallboards, and the left side of wallboard on the leftmost and the right side of wallboard on the rightmost are equipped with the joint spare, and connecting piece, joint spare link to each other with the vertical keel who fixes on the former wall body that needs to decorate respectively.
