Description

Technical Field

[0001] The utility model belongs to the technical field of building construction tool design, and particularly relates to a yin-yang angle strip which can be spliced ​​at will to adjust the angle and length. Background Art

[0002] Yin-Yang corner line, also known as Yin-Yang corner line closing strip or Yin-Yang corner strip. It is a strip-shaped auxiliary strip used for painting and painting to assist in making corners and make the molding effect more beautiful. Common materials are PVC, aluminum alloy, and stainless steel. The function of the anti-slip teeth or hole-shaped patterns on the bottom plate is to fully combine with the original wall and become more solid. Through the study of Yin-Yang corner lines, it is found that when the wall plastering work is completed and the finishing project is carried out, in order to ensure the finishing effect, when constructing the putty base, the Yin-Yang corner strips are usually pasted at the plastering free corners; after pasting, putty construction is carried out on a large area, and after multiple batches of putty grinding work, the surface layer is painted. However, when the wall is an irregular angle, such as a lattice-type shape, it is difficult to fold and splice the ordinary corner strips, and the corner strips need to be cut multiple times and the effect of the junction is poor. In order to solve the problem of irregular corners on the wall, a Yin-Yang corner strip with adjustable angles and lengths is specially invented. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a Yin-Yang corner strip that can be spliced ​​arbitrarily to adjust the angle and length, thereby solving the problem of irregular-shaped corners of walls and the cumbersome splicing of ordinary Yin-Yang corner strips.

[0004] The utility model achieves the above technical objectives through the following technical means.

[0005] A Yin-Yang corner strip that can be spliced ​​at will to adjust the angle and length is an integrated symmetrical structure, including a long strip of corner line, L-shaped exposed corner surfaces are arranged on both sides of the corner line, and the other side of the exposed corner surface is provided with a base surface, and the base surface is overall lower than the exposed corner surface, and the base surface is provided with a mounting hole for installing a connecting buckle; the angle formed between the corner line and the exposed corner surface is greater than 90°, and the size of the angle is determined according to the angular requirements required for construction; the Yin-Yang corner strips are cut and spliced ​​to form a shape matching the special-shaped corner, and the Yin-Yang corner strips are fixed by connecting buckles.

[0006] Furthermore, the base surface is made of a rough metal with double rows of holes punched in it, and has a width of 25 mm.

[0007] Furthermore, the exposed corner surface is made of metal with the same color as the wall and has a width of 15 mm.

[0008] Furthermore, the width of the bent portion of the exposed edge and corner surface is 2 mm, and the overall surface of the base surface is 2 mm lower than the exposed edge and corner surface.

[0009] Furthermore, the angle line width is 2 to 3 mm.

[0010] The utility model has the following beneficial effects:

[0011] The utility model can be mass-produced and processed as needed, which is convenient for production and material allocation. Moreover, since it has its own corners, there is no need to make Yin-Yang corners. The construction is convenient and quick, and the molding effect can be effectively guaranteed. Moreover, multiple corner strips can be folded and spliced ​​at will to achieve flexible adjustment of the overall angle and length, that is, it can be flexibly adjusted according to the shape of the lattice, solving the problem of irregular corners of the wall and the cumbersome splicing of ordinary Yin-Yang corner strips.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0018] like Figure 1 , 2 As shown, the Yin-Yang corner strips described in the utility model that can be spliced ​​at will to adjust the angle and length are an integrated symmetrical structure, including an embedded base surface 1, an exposed corner surface 2, a connecting buckle 4, and a corner line 3. L-shaped exposed corner surfaces 2 are arranged on both sides of the corner line 3, and the other side of the exposed corner surface 2 is arranged on the embedded base surface 1.

[0019] like Figure 1 , 2As shown, the base surface 1 is made of rough metal with double rows of holes. The purpose of using rough metal is to ensure better adhesion and bonding with putty and wall during subsequent use; the width of the base surface 1 is 25mm, and the width of the bent part of the exposed edge surface 2 is 2mm, that is, the overall size of the base surface 1 is 2mm lower than the exposed edge surface 2, in order to ensure that the final finishing surface is consistent with the exposed edge surface 2.

[0020] like Figure 1 , 2 As shown, the exposed corner surface 2 is made of metal with the same color as the wall, and its width is 15 mm. Putty and paint can be directly applied on its surface. If there is metal of the same color, the metal color can be directly used.

[0021] like Figure 1 , 2 As shown, the width of the corner line 3 is 2 to 3 mm, and the angle formed between the corner line 3 and the exposed corner surface 2 is greater than 90°. The specific size is reasonably designed according to the angle requirements required for construction. The purpose is to ensure natural lines and angles, without the need for workers to trim the angles, making the overall lines more beautiful.

[0022] like Figure 3 , 4 As shown, the connecting buckle 4 matches the hole opened on the base surface 1 to achieve the connection between the positive and negative corner strips.

[0023] The construction method of the Yin-Yang corner strips that can be spliced ​​at will to adjust the angle and length of the utility model is as follows:

[0024] First, cut and splice the Yin and Yang corner strips according to the shape of the wall and the lattice, and then fix them with the connecting buckle 4;

[0025] Then, plastering and puttying are carried out by bonding the plastering base surface 1 to the original wall;

[0026] Then punch holes to strengthen the bonding strength between putty, edge strips and surface materials;

[0027] Then apply putty to the entire surface, cut the scraper into the same angle, and scrape according to the angle;

[0028] Then after sanding, the base layer can be repaired and smoothed and painted.

[0029] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
