[0030] The following will further describe the present application in detail Figure 1-2 with reference to the attached

[0031] An embodiment of the present application discloses an indoor external corner guard strip.

[0032] Referring to Figure 1 and Figure 2 , an indoor external corner guard strip includes a turning portion 1. Along the length direction of the guard strip, the cross-section of the turning portion 1 is arc-shaped. The turning portion 1 is used to cover the edges and corners of the wall external corner, reducing the possibility of people being injured when colliding with the edges and corners of the wall, thereby improving the safety of using the guard strip. On both sides of the arc-shaped end of the turning portion 1, there are fixedly connected wall-attaching portions 2. The two wall-attaching portions 2 are vertically arranged. On the side of the wall-attaching portion 2 away from the turning portion 1, there is a fixedly connected tightening portion 3, and the tightening portion 3 is embedded in the cement mortar.

[0033] When installing the guard strip, apply a certain thickness of cement mortar on two mutually perpendicular walls at the external corner of the wall. Place the guard strip on the external corner of the wall. The outer sides of the two wall-attaching portions 2 are respectively parallel to the cement mortar applied on the two walls, forming a frame surrounded by the cement mortar, the wall, the turning portion 1 and the wall-attaching portion 2. The tightening portion 3 is located inside the frame. Subsequently, pour cement mortar into the frame. After the cement mortar hardens and dries, the wall-attaching portion 2 fits on the wall smeared with cement mortar, and the tightening portion 3 is embedded in the cement mortar, so that the guard strip is firmly installed on the wall, reducing the possibility of the guard strip falling off and improving the installation firmness of the guard strip.

[0034] The turning portion 1 includes a turning member 11 and a connecting member 12. The length direction of the turning member 11 is consistent with the length direction of the guard strip. The cross-section of the turning member 11 is arc-shaped. The number of the connecting members 12 is two, and they are symmetrically and fixedly connected to both sides of the arc-shaped end of the turning member 11. The side of the connecting member 12 away from the turning member 11 faces the outside of the turning member 11, so that the connecting member 12 protrudes outside the turning member 11. The side of the connecting member 12 away from the turning member 11 is fixedly connected to the side of the wall-attaching portion 2 away from the tightening portion 3, so that the wall-attaching portion 2 and the turning member 11 are transitionally connected through the connecting member 12, reducing the possibility of people being injured when colliding with the edges and corners.

[0035] The side of the connecting member 12 away from the wall-attaching portion 2 is inclined towards the end away from the tightening portion 3, so that the included angle between the outer wall of the wall-attaching portion 2 and the outer wall of the connecting member 12 and on the inner side of the guard strip is greater than 90°. Furthermore, the wall-attaching portion 2 is smoothly transitioned to the turning member 11. The range of the central angle corresponding to the arc length of the arc surface of the turning member 11 is greater than 0° and less than 90°, so that the connection parts between the wall-attaching portion 2, the turning member 11 and the tightening portion 3 are exposed on the outside, facilitating the cleaning of the connection parts, improving the cleaning convenience, and improving the aesthetics of the guard strip.

[0036] The wall - attaching part 2 includes attaching members 21. The two attaching members 21 are vertically arranged. The turning member 11 is located at the right - angle formed by the two attaching members 21. One side of the attaching member 21 away from the turning member 11 is fixedly connected to the fastening part 3, and the connection between the attaching member 21 and the fastening part 3 is bevel - angled.

[0037] After the corner guard is fixedly installed on the wall through cement mortar, it is necessary to level the side of the cement mortar outside the corner guard parallel to the wall and the outer wall of the attaching member. The connection between the attaching member 21 and the fastening part 3 is set to be bevel - angled. When leveling the wall surface, while increasing the contact area between the corner guard and the outside cement mortar to make the connection more firm, the bevel - angled shape is conducive to the bevel transition of the leveling operation, thus reducing the possibility of leveling operation errors.

[0038] The turning member 11 is located within the right - angle included angle formed by the extensions of the two perpendicular attaching members 21.

[0039] The turning member 11 forms an inward - sunken convex arc - shaped surface at the outside corner of the wall corner, further reducing the possibility of injury caused by collision with the turning member 11. While improving the safety of using the corner guard, it also improves the aesthetics of the entire structure, making the structure look cleaner and more beautiful.

[0040] The fastening part 3 includes a first fastening member 31 and a second fastening member 32. The first fastening member 31 and the second fastening member 32 are fixedly connected in a bent shape, and the bending point is located at the connection between the first fastening member 31 and the second fastening member 32. One side of the first fastening member 31 away from the second fastening member 32 is fixedly connected to the attaching member 21. The first fastening member 31 is perpendicular to the attaching member 21. Both the first fastening member 31 and the second fastening member 32 are embedded in the cement mortar.

[0041] When the cement mortar hardens, the first fastening member 31 and the second fastening member 32 are subjected to loads from different directions of the cement mortar, providing better bending and torsional resistance performance, thereby enhancing the overall firmness and reducing the possibility of the corner guard falling off.

[0042] One side of the second fastening member 32 away from the first fastening member 31 is located on the side of the first fastening member 31 close to the attaching member 21. The second fastening member 32 is bent towards the inside of the corner guard with the connection between the first fastening member 31 and the second fastening member 32 as the bending point, and the included angle between the inner wall of the first fastening member 31 and the inner wall of the second fastening member 32 is an acute angle. When the cement mortar hardens, the second fastening member 32 can better hook the cement mortar, providing a stronger anchoring force for the installation of the corner guard. And when the corner guard is subjected to tensile force, it can penetrate into the cement mortar through the shapes of the first fastening member 31 and the second fastening member 32, thereby providing better anti - pull - out performance and further improving the installation firmness of the corner guard.

[0043] To improve the overall installation stability of the corner guard strip and reduce the possibility of the corner guard strip cracking due to external forces such as tension and vibration, the turning piece 11, the connecting piece 12, the fitting piece 21, the first fastening piece 31 and the second fastening piece 32 are integrally formed, thereby improving the firmness of the installation of the corner guard strip.

[0044] In the production of existing granite corner guard strips, the cutting and grinding operations of granite will generate a large amount of dust and noise, which are likely to damage the respiratory and hearing systems of workers. At the same time, the dust emitted into the air also pollutes the surrounding environment. Moreover, when handling the corner guard strip, the corner guard strip made of granite is heavy, which is not conducive to the handling and installation of the corner guard strip and is likely to cause injuries to workers. A large amount of sewage and slurry will also be generated during the production of granite strips, which cannot be recycled and reused, causing environmental pollution. And during the entire processing of the corner guard strip, a large amount of energy, including electricity and water resources, is consumed, which may impose a certain burden on the environment and the power consumption is large. To solve the above problems, in this embodiment, the corner guard strip is made of metal, such as metals like stainless steel and aluminum alloy.

[0045] The implementation principle of an indoor external corner guard strip in an embodiment of this application is as follows: The corner guard strip is installed at the external corner of the wall. The turning piece 11 in an arc shape covers and blocks the right angle at the external corner of the wall, reducing the possibility of people being injured when colliding with the external corner and improving safety. Cement mortar is poured between the wall and the corner guard strip. After the cement mortar hardens, the inner wall of the fitting piece 21 closely adheres to the cement mortar, and the first fastening piece 31 and the second fastening piece 32 are embedded in the cement mortar, thereby firmly installing the corner guard strip on the wall and reducing the possibility of the corner guard strip falling off, improving the installation firmness of the corner guard strip.

[0046] The above are all the preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application in sequence. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
