[0019] like Figure 1 The structure of a positive corner line shown in the figure is composed of a line body 1 and a decorative board 2 and a gypsum board 3 arranged on both sides of the line body 1. The line body 1 is in the shape of an elongated strip and includes an L-shaped fixing portion 4 that fits the positive corner of the wall, a positive corner portion arranged outside the corner of the fixing portion 4, and a first connecting portion 5 and a second connecting portion 6 respectively disposed on either side of the positive corner portion. The gypsum board 3 and the decorative board 2 are fixed to the positive corner portion via the first connecting portion 5 and the second connecting portion 6, respectively, so that the positive corner portion is exposed in the connection area between the gypsum board 3 and the decorative board 2. The line body 1 is arranged at the positive corner of the wall and includes a fixing portion 4 that fixes the wall, a positive corner portion exposed to form a positive corner line, and a first connecting portion 5 and a second connecting portion 6 for connecting the decorative board 2 and the gypsum board 3. The line body 1 not only fixes the decorative board 2 and the gypsum board 3, but also uses the positive corner portion on the line body 1 to form an exposed positive corner line, ensuring that the positive corner line is set straight, convenient to use, and improves the aesthetics.
[0020] In actual operation, the wire body is formed by integral extrusion (such as Figure 2As shown in FIG5 , the external corner portion includes a connecting surface 7 connected to the gypsum board 3 and a connecting plate 8 smoothly connected to the decorative board 2. The connecting plate 8 is detachably mounted on the external corner portion and vertically spliced with the connecting surface 7 to form an exposed external corner line between the connecting plate 8 and the connecting surface 7. The connecting plate 8 and the connecting surface 7 are respectively spliced with the decorative board 2 and the gypsum board 3. The corresponding edges of the connecting plate 8 and the connecting surface 7 are vertically spliced to form a straight external corner line. The connecting surface 7 and the connecting plate 8 are pre-formed to ensure that the external corner line is straight, effectively improving the aesthetics. The external corner line will not bend due to human factors such as excessive application of the putty layer 9, effectively improving the quality of decoration and reducing the need for rework.
[0021] During installation, first, the fixing part 4 is attached to the external corner of the wall, the fastener passes through the avoidance groove 11 and is inserted and fixed in the corresponding wall, and the fixing part 4 is fixed to the wall so that the first connection part 5, the second connection part 6 and the external corner part are all reliably positioned; then, a connecting plate 8 with the same decorative pattern as the decorative panel 2 is selected, the connecting plate 8 is installed on the corresponding buckle groove 10 and vertically spliced with the connecting surface 7 to form a external corner line; then, the gypsum board 3 and the decorative panel 2 are respectively attached parallel to the corresponding wall and installed on the corresponding first connection part 5 and the second connection part 6; finally, a putty layer 9 is applied on the gypsum board 3, and the putty layer 9 is flush with the connecting surface 7.
[0022] After installation, the putty layer 9 and the decorative panel 2 respectively cover the walls on both sides of the external corner, and there is no need to precisely process the putty layer 9 to form the external corner line. This ensures that the external corner line can be assembled through prefabricated parts produced in advance, effectively maintaining straightness, and effectively reduces the processing difficulty of the putty layer 9, making it convenient to quickly apply the putty layer 9.
[0023] In actual operation, the edge of the connecting surface 7 close to the connecting plate 8 and the edge of the connecting plate 8 close to the connecting surface 7 are both at a 45° acute angle, so that the connecting surface 7 and the connecting plate 8 are vertically spliced. The edge of the connecting plate 8 close to the connecting surface 7 is at a 45° acute angle, and the edge of the connecting surface 7 close to the connecting plate 8 is at a 45° acute angle, which not only ensures that the two can match and splice to form a positive angle line with a 90° angle, but also ensures that the corresponding edges of the connecting plate 8 and the connecting surface 7 have good structural strength, preventing the situation where it is easy to be bumped and damaged due to too small an angle, thereby ensuring that the positive angle line is straight and complete.
[0024] In actual operation, the first connecting portion 5 is provided with a first retaining member, onto which the gypsum board 3 is fastened via a first retaining slot provided in its side wall, thereby securing the gypsum board 3 to the linear body 1.

The gypsum board 3 is positioned and secured by the first connecting portion 5, creating a height difference between the exposed surface of the gypsum board 3 facing away from the wall and the connecting surface 7. Applying the putty layer 9 to the gypsum board 3 allows for a smooth connection with the connecting surface 7, enhancing the aesthetics by improving the flatness of the putty layer 9 and the connecting surface 7. The gap between the connecting surface 7 and the first connecting portion 5 is covered by the putty layer 9.
[0025] In actual operation, the outer corner portion includes a buckle groove 10 provided at the corner of the fixing portion 4, and the connecting plate 8 is buckled on the buckle groove 10 and smoothly connected with the corresponding decorative plate 2 (such as Figure 3 (As shown). The exposed surface of the adapter plate 8 has the same decorative pattern as the exposed surface of the decorative panel 2. The adapter plate 8 is independently processed and formed, which not only facilitates disassembly and assembly with the buckle groove 10 on the external corner, but also allows for pre-setting of various decorative patterns as needed, ensuring compatibility with various decorative panels 2. This ensures that the decorative panel 2 and adapter plate 8 can be assembled and cover the entire wall surface, enhancing the aesthetics.
[0026] In practice, the second connecting portion 6 is provided with a second retaining member, onto which the decorative panel 2 is fastened via a second retaining slot provided in its sidewall, thereby securing the decorative panel 2 to the cord body 1. The second connecting portion 6 secures the decorative panel 2 in place, ensuring a tight and smooth connection between the decorative panel 2 and the connecting plate 8. The gap between the second connecting portion 6 and the decorative panel 2 is concealed by the connecting plate 8, enhancing the aesthetics.
[0027] In actual operation, the two ends of the fixing portion 4 are respectively attached to the corresponding wall surface and fixed by fasteners.
