[0019] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 3 The application will be described in further detail.

[0020] The external corner strip and the internal corner strip are collectively referred to as a corner piece, and refer to Figure 1 and Figure 2 include a first edge strip 1 and a second edge strip 2 made of PVC plastic, the first edge strip 1 and the second edge strip 2 are both in the form of a rectangle, the first edge strip 1 and the second edge strip 2 are fixedly connected to form an L-shaped structure, specifically, the long edges of the first edge strip 1 and the second edge strip 2 are fixed to each other, when it is an external corner strip, the included angle between the first edge strip 1 and the second edge strip 2 is slightly less than 90 degrees, and when it is an internal corner strip, the included angle between the first edge strip 1 and the second edge strip 2 is slightly greater than 90 degrees, in use, the corner piece is installed at the corner of a wall, and then operations such as painting gypsum and scraping putty are performed.

[0021] A plurality of perforations 5 are formed in the first edge strip 1 and the second edge strip 2, and the plurality of perforations 5 are uniformly distributed on the first edge strip 1 and the second edge strip 2, when the gypsum is painted, the gypsum will not only be painted on the first edge strip 1 and the second edge strip 2, but also be painted and fixed on the wall through the perforations 5, the fixing of the corner piece and the wall is more firm through the filling of the perforations 5, and the situation of the corner piece falling off is reduced.

[0022] The first edge strip 1 is provided with a first breaking line 3, the first breaking line 3 is arranged along the length direction of the first edge strip 1, the first edge strip 1 is divided into a connecting part 11 and a detachable part 12 by the first breaking line 3, and the first breaking line 3 divides the perforation on the first breaking line into two half holes, the connecting part 11 is fixedly connected with the second edge strip 2, when encountering the arc-shaped wall construction, the detachable part 12 can be separated from the connecting part 11 through the first breaking line 3, at this time, the remaining connecting part 11 and the second edge strip are used to place the second edge strip 2 on the arc-shaped wall surface, because the connecting part 11 is provided with a plurality of half holes along the length direction, when the second edge strip 2 is bent, the connecting part 11 will be deformed into the half hole due to the arrangement of the half hole, so that the connecting part 11 can be bent, the bending curvature of the connecting part 11 is small, and the process requirement of the putty scraping is met, the bent second edge strip 2 and the connecting part 11 are attached on the arc-shaped wall, and then the plaster and other operations are carried out, so as to ensure the flatness of the arc-shaped wall surface after painting.

[0023] Further, the second edge strip 2 is also provided with the first breaking line 3, the first breaking line 3 on the second edge strip 2 is arranged along the length direction of the second edge strip 2, the second edge strip 2 is also divided into a connecting part 11 and a detachable part 12 by the first breaking line 3, the connecting part 11 of the second edge strip 2 is fixedly connected with the bending part of the first edge strip 1, in use, the detachable part 12 of the second edge strip 2 can be detached and used together with the first edge strip 1, the detachable part 12 on the second edge strip 2 or the first edge strip 1 can be separately detached according to different construction conditions, or both detachable parts 12 are detached, and the applicability of the corner piece is increased through the arrangement of the two first breaking lines 3.

[0024] Referring to Figure 1 and Figure 3 Further, the end of the first edge strip 1 and the end of the second edge strip 2 are provided with a second breaking line 4, and the second breaking line 4 forms an included angle with the edge of the first edge strip 1 or the second edge strip 2.

[0025] The second breaking line 4 on the first edge strip 1 is introduced below, and the second breaking line 4 on the second edge strip 2 is arranged in the same way as the second breaking line 4 on the first edge strip 1.

[0026] The second breaking line 4 and the short side of the first edge strip 1 form an included angle. Generally, when installing the corner piece at the three-wall corner, a fillet strip needs to be installed at each of the three corners. At the three-wall corner position, the three fillet strips interfere with each other. At this time, a scissors is usually used to cut an included angle of less than 45° on the corner piece to avoid interference. However, it is troublesome and difficult to manually cut an included angle of about 45°. The second breaking line 4 is arranged in the present application. When the corner piece needs to be cut, the corner piece can be directly removed through the breaking line without manual cutting.

[0027] Further, the included angle is between 30° and 45°. In the present embodiment, the included angle is preferably 45°. When the included angle is 45°, the three corner pieces can be closely fitted and installed more tightly.

[0028] In the present application, the first breaking line 3 and the second breaking line 4 are made by high-temperature knife fast pressing or other methods. The depth of the pressing breaking line is 40-60% of the thickness of the edge strip. When a part of the edge strip is broken along the breaking line, it is relatively easy, and the strength of the edge strip is not greatly different from that without the breaking line, which ensures that the edge strip is used well without being broken and is easy to break, so that a product can be used in multiple states and is flexible for construction. In other embodiments, the knife can be used to cut or other methods can be used to make the breaking line.

[0029] When the corner piece is used at the exposed corner where two wall surfaces meet, the two surfaces of the corner piece close to each other are attached to the exposed corner, and then plastering or other operations are performed.

[0030] When the corner piece is used at the fillet corner where two cavities meet, the two surfaces of the corner piece away from each other are attached to the wall, and then plastering or other operations are performed.

[0031] Before the arc-shaped wall surface is painted, the dismounting part 12 is dismounted from the first edge strip 1 and / or the second edge strip 2, the curved connecting part and the first edge strip 1 or the second edge strip 2 are attached to the arc-shaped wall surface, and then plastering or other operations are performed.

[0032] When the corner where three walls meet is constructed, three corner pieces are prepared, each corner piece is dismounted into a sharp corner through the two second breaking lines 4 on each corner line, the sharp corners are arranged at the corner, the three sharp corners are abutted to each other, and then plastering or other operations are performed on the three corner pieces.

[0033] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
