Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a wall corner chamfering device for building decoration. Background Art

[0002] Yin and Yang angles are one of the building structures. Yin angles refer to recessed corners, such as the angle between the ceiling and the surrounding walls; Yang angles refer to protruding corners, such as the angle formed by two walls at the corner of a walkway. If the error of the Yin and Yang angles of the wall is large, it can be seen at a glance, affecting the aesthetics of home decoration, and will also cause cabinets, furniture, etc. to be installed and placed unsmoothly, resulting in space waste. Yin and Yang angles are mostly 90 degrees. When inspecting the Yin and Yang angles of the wall, the Yin and Yang angles are required to meet the requirements of perpendicularity and parallelism between the edge line and the main body of the house, and the wall corners must be straight and square.

[0003] Grinding is a type of surface modification technology, which generally refers to a processing method that uses sandpaper or other materials to rub the surface of an object to change the degree of friction roughness of the surface of the object, making the surface of the object smoother and more refined. When a building is completed and needs to be decorated, in order to improve the safety performance of the building in subsequent use, it is sometimes necessary to grind and chamfer the external corners generated in the building.

[0004] The existing chamfering method is usually mainly manual grinding. When manually chamfering the external corners of a building, a large amount of dust will be generated on site, which is not only not conducive to environmental protection, but also causes a certain degree of damage to the health of construction workers, and is inconvenient to use.

[0005] Therefore, we make improvements to this and propose a wall corner chamfering device for building decoration. Utility Model Content
