[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] See also Figures 1 to 3 A corner strip for controlling the thickness of wall plastering, the corner strip structure is an "M"-shaped corner strip, the two top angles of the "M"-shaped corner strip are outer folding angles 3, and the middle downward angle is a middle folding angle 4; the first side strip 1 and the second side strip 2 of the "M"-shaped corner strip can be freely bent and set. During the installation process, the middle folding angle 4 is inserted into the cement ash layer at the building's outer corner 6 or the building's inner corner 7. By adjusting the angle formed by the first side strip 1, the second side strip 2 and the outer folding angle 3, the wall plastering thickness is kept consistent with the angle formed by the first side strip 1 and the second side strip 2, thereby realizing the control of the wall plastering thickness.

[0022] In this embodiment, a small external corner 5 matching the external corner 6 of the building is extended outward from the top of the middle folded corner 4. The angle of the small external corner 5 is adjusted to fit the small external corner 5 tightly with the external corner 6 of the building, thereby making the corner strip fit more closely with the external corner 6 of the building.

[0023] In this embodiment, the angle formed between the first side strip 1 and the second side strip 2 of the outer corner 3 has a wide range of angles and can be adjusted arbitrarily between 0 and 180 degrees. This design allows the side strips on both sides of the outer corner 3 to be freely matched, thereby meeting different usage requirements.

[0024] Specifically, when plastering the building's external corner 6, the small external corner 5 is closely attached to the building's external corner 6, the angles of the first side strip 1 and the second side strip 2 are adjusted, the distances between the first side strip 1 and the second side strip 2 and the building's wall are adjusted, and then plastering is performed to achieve thickness control of the plastering at the building's external corner 6 by the corner strip.

[0025] When plastering the building's inner corner 7, bend the two side edges of the small outer corner 5 to fit together with the two side edges of the middle fold angle 4, insert the middle fold angle 4 into the cement plaster layer of the building's inner corner 7, then adjust the angles of the first side strip 1 and the second side strip 2, adjust their distances from the walls on both sides of the building's inner corner 7, and then plastering is performed, thereby achieving thickness control of the corner strips at the plastering of the building's inner corner 7.

[0026] In this embodiment, fixing holes are provided on both sides of the small external corner 5, and fixing components such as nails are used to fix the diagonal strips and the building wall.

[0027] In this embodiment, the material of the corner strip is a deformable material, which can flexibly adapt to the angles of the first side strip 1 and the second side strip 2, as well as the angle of the small external angle 5. This material has excellent flexibility and plasticity, and can easily adapt to various angle changes, making our products more flexible and convenient during installation, and can be flexibly adjusted according to actual needs, so as to better meet the needs of users.

[0028] The working principle of this utility model:

[0029] During the process of plastering the building external corner 6, the small external corner 5 needs to be adjusted to a suitable angle to ensure that the small external corner 5 can fit closely with the building external corner 6. Then, fasteners such as nails are used to fix the corner strip to the wall corner through the fixing holes set on the small external corner 5, and then the angle of the outer folded corner 3 is adjusted to meet the thickness requirement of the wall corner plastering, thereby realizing accurate control of the plastering thickness.

[0030] When plastering the building's inner corner 7, it is necessary to fold the two side edges of the small outer corner 5 to be close to the middle corner 4, and then insert the middle corner 4 into the cement ash layer. Next, adjust the first side strips 1 and the second side strips 2 on both side edges of the outer corner 3 so that the outer corner 3 meets the wall corner plastering thickness requirements.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
