Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a plastering engineering anti-cracking positive and negative corner structure with a filling structure. 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 Yin and Yang angles on the wall is large, it can be seen at a glance, affecting the aesthetics of home decoration, and also causing cabinets, furniture, etc. to be installed and placed unsmoothly, resulting in space waste. Yin and Yang angles are mostly 90 degrees. When inspecting Yin and Yang angles on the wall, it is required that the edge line and the main body of the house are perpendicular and parallel to each other, and the corners are straight and square.

[0003] During the construction process, the existing wall corners will be pasted with internal corner strips, external corner strips and mesh cloth. The internal corner strips, external corner strips and mesh cloth are pasted with latex paint. The installation stability of the internal corner strips and external corner strips is poor. At the same time, the internal corner strips, external corner strips and mesh cloth will protrude from the wall. When spraying the paint, in order to ensure the flatness of the paint surface, the spraying thickness of the latex paint will be reduced at the pasting points of the internal corner strips, external corner strips and mesh cloth. After the thickness of the paint liquid is reduced, it will cause the installation points of the internal corner strips and external corner strips to crack easily. In order to solve the above problems, the present application proposes a plastering project anti-cracking internal and external corner structure with a filling structure. Utility Model Content

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to propose a plastering engineering anti-cracking corner structure with a filling structure, which can improve the stability of the installation of the corners. At the same time, the mesh cloth is located in the inner cavity of the pasting groove, so that the outer surface of the mesh cloth can be flush with the wall surface. When painting the outer and inner paint surfaces, the uniformity of the paint thickness can be guaranteed, and the paint surface is not thin due to the protrusion of the mesh cloth from the wall after being pasted. The paint surface can be effectively prevented from cracking, so as to solve the problems raised in the background technology.

The positive corner strip and the negative corner strip are respectively connected to the dovetail splicing grooves on the outer wall and inner wall surfaces of the wall through the dovetail splicing seat.

[0008] An optimal technical solution of the utility model is that the inner cavity of the dovetail splicing seat is a hollow structure, and the inner cavity is movably connected with a filling cotton strip.

[0009] An optimal technical solution of the utility model is that chamfers are provided on both sides of the dovetail splicing groove, and the dovetail splicing seat abuts against the chamfered surface during assembly.

[0011] An optimal technical solution of the utility model is that mesh cloth is pasted on the outer wall surface of the external corner strip and the inner wall surface of the internal corner strip.

[0012] The preferred technical solution of the utility model is that the mesh cloths are all located in the inner cavity of the pasting groove, and the outer surfaces of the mesh cloths are flush with the outer wall surface and the inner wall surface of the wall respectively.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a plastering engineering anti-cracking corner structure with a filling structure, which can improve the stability of the installation of the corners. At the same time, the mesh cloth is located in the inner cavity of the pasting groove, so that the outer surface of the mesh cloth can be flush with the wall surface. When painting the outer and inner paint surfaces, the uniformity of the paint thickness can be guaranteed, and the paint surface is not thin due to the mesh cloth pasting point protruding from the wall, which can effectively prevent the paint surface from cracking.

[0016] The mesh cloth is located in the inner cavity of the pasting groove, so that the outer surface of the mesh cloth can be flush with the wall surface. When painting the outer and inner paint surfaces, the uniformity of the paint thickness can be guaranteed, and the mesh cloth pasting place can be avoided from protruding from the wall, resulting in a thinner paint surface, which can effectively avoid paint cracking.

The mesh cloth 13 is located in the inner cavity of the pasting groove 14, and the outer surface of the mesh cloth 13 is flush with the outer wall surface and the inner wall surface of the wall 1 respectively.

[0033] Mesh cloth 13 is pasted on the outer wall of the external corner strip 5 and the inner wall surface of the internal corner strip 6, and the outer paint surface 2 and the inner paint surface 3 are painted on the surface of the mesh cloth 13, so that the outer paint surface 2 and the inner paint surface 3 can form an integral structure at the connection between the wall 1 and the external corner strip 5 and the internal corner strip 6, thereby avoiding cracking of the outer paint surface 2 and the inner paint surface 3.

[0034] The working principle and use process of the utility model are as follows: a dovetail splicing groove 4, an adhesive groove 14 and a corresponding hole 11 are respectively opened on the outer wall surface and the inner wall surface of the wall body 1; the inner wall surface of the external angle strip 5 and the outer wall surface of the internal angle strip 6 are respectively connected with the dovetail splicing groove 4 on the outer wall surface and the inner wall surface of the wall body 1 through a dovetail splicing seat 7; the inner cavity of the dovetail splicing seat 7 is a hollow structure; the dovetail splicing seat 7 abuts against the chamfer 8 on the dovetail splicing groove 4; the chamfer 8 guides the two sides of the dovetail splicing seat 7; when pressed down, the dovetail splicing seat 7 can be contracted inwardly, thereby facilitating the rapid assembly of the external angle strip 5 and the internal angle strip 6; at this time, the countersunk fixing holes 10 on the surfaces of the external angle strip 5 and the internal angle strip 6 coincide with the corresponding holes 11 on the surface of the wall body 1; expansion bolts are inserted into the corresponding holes 11; countersunk fixing bolts 12 penetrate the countersunk fixing holes 10 and are threadedly connected with the expansion bolts in the corresponding holes 11; the external angle strip 5 and the internal angle strip 6 can be lifted.
