Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a negative angle line. Background Art

[0002] At present, the inner corners of building walls are kept flat and straight by scraping plaster. Such operation is very demanding on the experience of the operators. Even for experienced masters, it is difficult to keep the inner corners flat and straight by scraping plaster alone. Therefore, many inner corners now have poor flatness, skewness, inconsistent upper and lower angles, etc., which will seriously affect the decoration effect and reduce the aesthetics in the minimalist decoration style, thus greatly affecting the decoration quality and effect of the building.

[0003] Now, when leveling the wall, most people use rib leveling. The steps of rib leveling are as follows: Dotting: Use gypsum cakes to find base points on the wall, connect the points and vertically connect them into lines and calibrate them with a spirit level. Rib leveling: Hold a ruler against the gypsum cake and punch out a rib perpendicular to the ground. Repeat the dotting and rib leveling process to make several ribs arranged side by side on the wall. After completing the above construction, several ribs arranged side by side will be left on the wall, and then wait for the ribs to dry and harden. Filling and leveling: Fill the gap with gypsum, and use a ruler to scrape and compact from bottom to top.

[0004] When using gypsum cakes to make points, it is necessary to connect the points and calibrate with a level to complete the rib punching. This process is very cumbersome and it is difficult to quickly make a structure that is convenient for rib punching. After the rib punching is completed, the detachment of the ruler can easily cause the ribs to deform. In addition, the rib punching process is easily affected by manual experience, resulting in insufficient flatness and verticality of the outer surface of the ribs, which ultimately leads to large errors in wall leveling. The precision of such leveling construction is limited, and it is easy to have insufficient wall flatness. When filling and leveling, due to the large roughness of the rib surface and the large width of the rib, the rib will have a relatively large friction resistance to the ruler, which is easy to cause the resistance of the ruler to scrape and smooth, and then it cannot be scraped and smoothed quickly, which is easy to affect the efficiency and quality of wall leveling. Therefore, the existing rib punching leveling has the problems of cumbersome on-site construction, insufficient precision, and low construction efficiency, which is easy to affect the efficiency and quality of house decoration.

[0005] At the same time, when the flatness of the two walls forming the inner corner is very poor or relatively poor, it is easy to affect the flatness and straightness of the inner corner, which can easily lead to the inner corner having poor flatness, skewness, inconsistent upper and lower angles, etc. And when the flatness of the wall is very poor or relatively poor, gaps are likely to appear between the furniture placed against the wall and the wall, which can easily make the wall appear uneven, tilted, or the furniture appear tilted, which can easily bring a poor visual experience and affect the improvement of the house grade. In addition, the above-mentioned gaps are easy for mosquitoes, dust, debris, etc. to enter, and the inside of the furniture needs to be cleaned frequently to ensure indoor hygiene, which can easily bring inconvenience to indoor cleaning.

[0006] In view of the above problems, it is very necessary to design a pre-buried internal angle line to improve the efficiency and quality of making internal angles. Summary of the invention

[0007] The purpose of the present invention is to solve the above-mentioned problems and shortcomings, and to provide a pre-embedded internal corner line, which adopts a internal corner line body with an angled radial cross section, and reference convex strips are respectively provided on the two inner surfaces of the internal corner line body, so that the two walls constituting the internal corner can be scraped very flat and straight, so as to ensure that the two walls constituting the internal corner have high flatness and verticality, and then a very standard and beautiful internal corner can be made, which can facilitate the construction of a building internal corner with high flatness, straightness, and a straight upper and lower angle, so as to improve the quality of building decoration. When the furniture is placed against the wall, the gap between the furniture and the wall is avoided, which can bring a better visual experience and facilitate indoor cleaning. The reliability and applicability of the pre-embedded internal corner line are very good. In addition, the overall structure of the pre-embedded internal corner line is also very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost.

[0008] The technical solution of the present invention is achieved in this way:

[0009] A pre-buried internal corner line, characterized in that it comprises a internal corner line body with an angled radial section, wherein reference convex strips are respectively arranged on the two inner surfaces of the internal corner line body; the top surface of the reference convex strip is an arched arc surface; the reference convex strip is a cone structure with a wide inside and a narrow outside; storage grooves are respectively opened on the two outer surfaces of the internal corner line body; the storage grooves also penetrate to the end surfaces of both ends of the internal corner line body; a plurality of through holes are respectively opened on the two inner surfaces of the internal corner line body and penetrate to the corresponding outer surfaces of the internal corner line body; each through hole penetrates the corresponding storage groove; the radial cross section of the internal corner line body is a right angle; ... Concave and convex parts are respectively arranged on the two inner surfaces of the angle line body, and the highest position of the protrusions of the two concave and convex parts is lower than the highest position of the protrusion of the reference convex strip on the corresponding side of the female angle line body; the distance from each convex point of the two concave and convex parts to the inner surface of the female angle line body gradually decreases in the direction away from the reference convex strip; it is ensured that the gypsum layer away from the reference convex strip is generally gradually thickened; the concave and convex parts are provided with embedding grooves; the embedding grooves can be used for embedding kraft paper; the concave and convex parts are wavy; a clearance notch is provided on the outer corner of the female angle line body; a concave strip groove is provided on one side of the inner corner of the female angle line body; the through hole is staggered with the concave and convex parts.

[0010] Preferably, the inner corner wire body is a profile structure.

[0011] Beneficial effects of the present invention: (1) In the embedded internal corner line of the present invention, a internal corner line body with an angled radial cross section is adopted, so that the embedded internal corner line can be matched with the internal corner of the wall, so that accurate installation can be achieved, and the applicability of the embedded internal corner line is very good. By respectively setting upper reference convex strips on the two inner surfaces of the internal corner line body, it can not only be used as a reference for installing the embedded internal corner line, but also as a reference line for scraping the walls on both sides of the internal corner. So that when scraping plaster on the wall, there is a very reliable reference, so that it is convenient to manually scrape a flat and straight wall surface on the wall to avoid the wall surface being skewed. This can ensure that the walls on both sides of the internal corner have a very high flatness and verticality, so that it is convenient for operators to scrape a very flat and straight internal corner on the internal corner of the building to avoid the internal corner being skewed, inconsistent upper and lower angles, etc. The use of the embedded internal corner line can greatly improve the decoration quality of the building, and the applicability of the embedded internal corner line is very strong.

[0012] (2) The embedded internal angle line can not only make reliable internal angles, but also be used to level the wall. Through the reference convex strip, a very accurate and reliable reference can be established, and the accuracy of this reference is minimally affected by the workers, which can greatly reduce the error of wall leveling and ensure that the reference has a very high flatness and verticality, thereby greatly improving the accuracy of wall leveling construction, and thus making it easy to make a wall with very high flatness and verticality. The embedded internal angle line can greatly improve the quality of wall leveling. The application of the embedded internal angle line can directly save the cumbersome "dotting" operation in the existing rib leveling, which can greatly reduce the difficulty of wall leveling and greatly improve the efficiency of wall leveling. By using the reference convex strip as the reference, there will be no problem of large roughness like the ribs produced by ribs, and the reference convex strip is in the shape of a strip, which can greatly reduce the friction between the ruler and the reference convex strip when filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and thus facilitating rapid scraping and leveling, which also helps to improve the efficiency and quality of wall leveling. The embedded internal angle line can not only greatly reduce the complexity of on-site construction, but also improve the accuracy and efficiency of construction, thus helping to improve the efficiency and quality of house decoration.

[0013] (3) The embedded inner corner line can easily create a wall with very high flatness and verticality, so that when the furniture is placed against the wall, there will be no gap between the furniture and the wall, so that the wall will not appear uneven or tilted, and the furniture will not appear tilted, which can bring a better visual experience and greatly improve the grade of the house. And when there is no gap between the furniture and the wall, mosquitoes, dust, debris, etc. can be prevented from entering the inside of the furniture. In this way, even if the inside of the furniture is not cleaned frequently, the hygiene of the room can still be guaranteed, which helps to improve the convenience of indoor cleaning.

[0014] (4) At the same time, the overall structure of the embedded internal angle line is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the three-dimensional structure of the embedded internal corner line in the present invention.

[0016] Figure 2 It is a schematic diagram of the cross-sectional structure of the embedded internal corner line in the present invention. DETAILED DESCRIPTION

[0017] like Figure 1 and Figure 2 As shown, the embedded internal corner line of the present invention comprises a internal corner line body 1 with an angled radial cross section, wherein reference convex strips 11 are respectively arranged on two inner surfaces of the internal corner line body 1.

[0018] In the embedded internal corner line of the present invention, a internal corner line body 1 with an angled radial cross section is used, so that the embedded internal corner line can be matched with the internal corner of the wall, so that accurate installation can be achieved, and the applicability of the embedded internal corner line is very good. By respectively setting the upper reference convex strips 11 on the two inner surfaces of the internal corner line body 1, it can not only be used as a reference for installing the embedded internal corner line, but also as a reference line for scraping the walls on both sides of the internal corner. So that when scraping plaster on the wall, there is a very reliable reference, so that it is convenient to manually scrape a flat and straight wall on the wall to avoid the wall being skewed. This can ensure that the walls on both sides of the internal corner have a very high flatness and verticality, so that it is convenient for the operator to scrape a very flat and straight internal corner on the internal corner of the building to avoid the internal corner being skewed, inconsistent upper and lower angles, etc. The use of the embedded internal corner line can greatly improve the decoration quality of the building, and the applicability of the embedded internal corner line is very strong.

[0019] The embedded internal angle line can not only make reliable internal angles, but also be used to level the wall. A very accurate and reliable reference can be established through the reference convex strip 11, and the accuracy of this reference is minimally affected by workers, which can greatly reduce the error of wall leveling and ensure that the reference has very high flatness and verticality, thereby greatly improving the accuracy of wall leveling construction, and thus making it easy to make walls with very high flatness and verticality. The embedded internal angle line can greatly improve the quality of wall leveling. The application of the embedded internal angle line can directly save the cumbersome "dotting" operation in the existing rib leveling, which can greatly reduce the difficulty of wall leveling and greatly improve the efficiency of wall leveling.

[0020] By using the reference convex strip 11 as the reference, there will be no problem of roughness like the ribs produced by punching, and the reference convex strip 11 is in strip shape, which can greatly reduce the friction between the ruler and the reference convex strip 11 during filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and then making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of wall leveling. The embedded internal angle line can not only greatly reduce the tediousness of on-site construction, but also improve the accuracy and efficiency of construction, thereby helping to improve the efficiency and quality of house decoration.

[0021] The embedded inner corner line can easily create a wall with high flatness and verticality, so that when the furniture is placed against the wall, there will be no gap between the furniture and the wall, so that the wall will not appear uneven or tilted, and the furniture will not appear tilted, which can bring a better visual experience and greatly improve the grade of the house. And when there is no gap between the furniture and the wall, mosquitoes, dust, and debris can be prevented from entering the inside of the furniture. In this way, even if the inside of the furniture is not cleaned frequently, the hygiene of the room can still be guaranteed, which helps to improve the convenience of indoor cleaning.

[0022] At the same time, the overall structure of the embedded internal angle line is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost.

[0023] like Figure 1 and Figure 2 As shown, the length direction of the two reference ridges 11 is consistent with the length direction of the internal corner line body 1. This not only ensures that the two reference ridges 11 have a longer length, but also facilitates the formation of a straight reference and the molding of the reference ridges 11, thereby helping to further improve the applicability of the embedded internal corner line.

[0024] like Figure 2 As shown, the top surface of the reference convex strip 11 is an arched arc surface 111. This not only serves as a very good reference, but also reduces the resistance of plastering on the reference convex strip 11, so as to facilitate the operator to apply plaster at the reference convex strip 11, thereby ensuring that the plastering can be carried out very smoothly, and then it is convenient to improve the efficiency of internal corner decoration, which helps to further improve the applicability of the embedded internal corner line.

[0025] like Figure 1 and Figure 2 As shown, the reference convex strip 11 is a cone structure with a wide inner side and a narrow outer side, which not only facilitates decoration, but also ensures that the reference convex strip 11 has a high structural strength, thereby helping to improve the reliability and applicability of the embedded inner corner line.

[0026] When actually installing the embedded internal corner line, several other leveling strips with reference convex strips can be embedded on the two walls forming the internal corner. In this way, a very reliable reference surface can be established by making the two reference convex strips 11 on the embedded internal corner line and the other reference convex strips on the corresponding side in the same vertical plane. This allows the gypsum mud to be scraped with this reference surface when filling the gypsum mud, so that it is easy to scrape out two wall surfaces with very high flatness and verticality, and then it is easy to build a very straight and beautiful internal corner.

[0027] like Figure 1 and Figure 2 As shown, storage grooves 13 are respectively provided on the two outer surfaces of the internal corner line body 1. The storage grooves 13 can be used to store plaster or glue to ensure that there is sufficient plaster or glue between the embedded internal corner line and the wall, so that the embedded internal corner line can be installed on the wall corner very stably, which helps to further improve the reliability of the embedded internal corner line.

[0028] like Figure 1 and Figure 2As shown, the storage groove 13 penetrates the outer wall of the internal angle line body 1. This makes it easy for excess plaster or glue to be discharged from the inner side of the embedded internal angle line to avoid them affecting the normal installation and positioning of the embedded internal angle line, which makes it easy to install the embedded internal angle line more quickly, thereby helping to further improve the convenience and accuracy of the installation and positioning of the embedded internal angle line.

[0029] Before installation, first apply plaster or glue on the internal corner of the building or the embedded internal corner line; then embed the embedded internal corner line into the internal corner of the building, and press the embedded internal corner line inward, so that the excess plaster or glue will be squeezed out from the inner side of the embedded internal corner line. Then use the light projected by the infrared level as a reference for adjusting the reference convex strip 11. Then, by pressing and tapping the internal corner line body 1 and / or the reference convex strip 11, and referring to the light projected by the infrared level, adjust the top surfaces of the two reference convex strips 11 to two virtual vertical planes respectively, so that a very reliable reference can be constructed through the reference convex strip 11, so that it is easy to make a wall with very high flatness and verticality, and then it is easy to make a very standard internal corner.

[0030] like Figure 1 and Figure 2 As shown, the storage groove 13 also penetrates the end surfaces of both ends of the inner corner wire body 1. This not only facilitates the storage of more plaster or glue, but also facilitates the molding of the storage groove 13, thereby facilitating the improvement of manufacturing convenience.

[0031] like Figure 1 and Figure 2 As shown, the two inner surfaces of the inner corner line body 1 are respectively provided with a plurality of through holes 14 penetrating to the corresponding outer surfaces of the inner corner line body 1. When installing the embedded inner corner line, the through holes 14 can facilitate the discharge of excess plaster or glue on the inner side of the embedded inner corner line, thereby avoiding excessive plaster or glue on the inner side of the embedded inner corner line, and then facilitating the quick fixation of the embedded inner corner line, which helps to further improve the installation efficiency of the embedded inner corner line. The through holes 14 can also facilitate the setting of plaster or glue penetrating the embedded inner corner line, thereby facilitating the more stable fixation of the embedded inner corner line on the inner corner of the building, and then helping to further improve the stability and reliability of the installation and positioning of the embedded inner corner line.

[0032] like Figure 1 and Figure 2 As shown, each through hole 14 passes through the corresponding storage groove 13. This makes it easier to discharge excess plaster or glue, and can further enhance the reliability and stability of the plaster or glue fixing the internal angle wire body 1.

[0033] like Figure 1As shown, the through holes 14 on the same side of the internal corner wire body 1 are arranged side by side along the length direction of the internal corner wire body 1. This not only facilitates the formation of a reliable internal corner wire body 1, but also reduces the influence of the opening of the through holes 14 on the structural strength of the internal corner wire body 1, thereby ensuring that the internal corner wire body 1 has high reliability.

[0034] like Figure 1 and Figure 2 As shown, the radial cross section of the internal angle line body 1 is in a right angle shape. This facilitates the standard 90-degree angle when constructing at the internal angle, which can ensure that the embedded internal angle line has high reliability and can meet the needs of most building internal angles, thereby ensuring that the embedded internal angle line has high applicability.

[0035] like Figure 1 and Figure 2 As shown, the two inner surfaces of the internal angle line body 1 are respectively provided with concave-convex parts 12, and the highest position of the two concave-convex parts 12 is lower than the highest position of the reference convex strip 11 on the corresponding side of the internal angle line body 1. The provision of the two concave-convex parts 12 can improve the adhesion between the two sides of the embedded internal angle line and the plaster, thereby ensuring that the embedded internal angle line can be very stably buried in the internal angle of the wall, and further ensuring that the plaster at the internal angle of the wall can be stably attached to the embedded internal angle line, which can greatly reduce the probability of cracking and falling of the plaster, which can facilitate the construction of a very reliable internal corner of the wall, and the reliability of the embedded internal angle line is very high.

[0036] like Figure 1 and Figure 2 As shown, the through hole 14 is staggered with the concave-convex part 12. In this way, the pre-embedded inner corner line can be ensured to have high structural strength through the concave-convex part 12, and the through hole 14 can be prevented from affecting the structural strength of the pre-embedded inner corner line, thereby ensuring that the pre-embedded inner corner line has high reliability.

[0037] like Figure 1 and Figure 2As shown, on the two inner surfaces of the internal corner wire body 1, the two concave-convex parts 12 are connected to the side walls of the corresponding reference convex strips 11 away from the inner corner of the internal corner wire body 1, and the distance from each convex point 121 of the two concave-convex parts 12 to the inner surface of the internal corner wire body 1 is gradually reduced in the direction away from the reference convex strips 11. By connecting the concave-convex parts 12 with the reference convex strips 11, they can play a role in reinforcing each other, which can not only enhance the reliability and stability of the connection between the reference convex strips 11 and the internal corner wire body 1, but also improve the reliability and stability of the concave-convex parts 12, thereby helping to improve the structural strength of the embedded internal corner wire, and further helping to further improve the reliability of the embedded internal corner wire. By adopting the concave-convex parts 12 with the above thickness structure, it can be ensured that the gypsum layer away from the reference convex strips 11 is generally gradually thickened, and the concave-convex parts 12 themselves facilitate the stable attachment of gypsum, which can effectively improve the stability and reliability of gypsum attachment to avoid the gypsum from falling off, thereby helping to further improve the reliability and applicability of the embedded internal corner wire. Furthermore, by connecting the two concave-convex portions 12 with the corresponding reference convex strips 11 respectively, the embedded internal angle line can be ensured to have a compact structure, thereby facilitating storage, transportation and installation.

[0038] like Figure 1 and Figure 2 As shown, the concave-convex part 12 is provided with an embedding groove 15. The embedding groove 15 can be used for embedding kraft paper, which can facilitate the stable and accurate positioning of the kraft paper on the embedded internal corner line, so as to facilitate a more gentle transition between the embedded internal corner line and the gypsum, and ensure that the embedded internal corner line can be more reliably connected to the gypsum, which helps to further improve the reliability of the embedded internal corner line. In addition, this can reduce the impact of thermal expansion and contraction and collision on the installation effect of the embedded internal corner line, so as to avoid cracking of the gypsum at the side of the embedded internal corner line in these cases, thereby ensuring that the internal corner of the building maintains a good decorative effect for a long time, which helps to further improve the reliability and applicability of the embedded internal corner line. By providing the embedding groove 15 on the concave-convex part 12. In this way, the kraft paper will be attached to the concave-convex part 12, which can limit the kraft paper through the concave-convex part 12, thereby facilitating the improvement of the reliability of the installation and positioning of the kraft paper, and thus ensuring that the embedded internal angle line has a very high reliability.

[0039] like Figure 1 and Figure 2 As shown, the embedding groove 15 is a strip groove, and the two ends of the embedding groove 15 are respectively penetrated to the two end surfaces of the inner corner line body 1. This can not only facilitate the formation of a more reliable embedding effect, but also facilitate the manufacturing and processing of the embedding groove 15.

[0040] like Figure 1 and Figure 2As shown, the groove wall of the embedding groove 15 is in the shape of a letter C. In this way, the embedding groove 15 can have a better limiting effect, which helps to improve the stability and reliability of the kraft paper embedding, thereby helping to further improve the reliability of the embedded inner corner line.

[0041] During installation, one end of the kraft paper is embedded in the embedding groove 15, and the other end of the kraft paper is away from the inner corner of the embedded inner corner line, and the kraft paper covers the side of the embedded inner corner line. This can meet the installation requirements.

[0042] like Figure 1 and Figure 2 As shown, the concave-convex part 12 is wavy. The structure of the concave-convex part 12 is very simple and reliable, so it can be conveniently formed in one piece, thereby helping to further improve the convenience of manufacturing the embedded inner corner line.

[0043] like Figure 1 and Figure 2 As shown, a clearance notch 16 is provided on the outer corner of the internal angle line body 1. This can achieve the purpose of staggering the sharp corners of the internal angle of the building, thereby preventing the concave-convex and crooked corners of the internal angle of the building from affecting the installation of the embedded internal angle line, which can facilitate the improvement of the convenience, stability and reliability of the installation and positioning of the embedded internal angle line. The clearance notch 16 can be used to store plaster or glue to ensure that there is sufficient plaster or glue between the embedded internal angle line and the wall, thereby ensuring that the embedded internal angle line can be installed on the wall very stably, which helps to further improve the reliability of the embedded internal angle line. After adopting the clearance notch 16, the installation of the embedded internal angle line can be satisfied without additional treatment of the internal angle of the building, which helps to improve the convenience and efficiency of installation.

[0044] like Figure 1 and Figure 2 As shown, the clearance gap 16 is in a right angle shape, which not only enables the clearance gap 16 to have a better clearance effect, but also facilitates the opening of the clearance gap 16, thereby helping to further improve the reliability and applicability of the embedded inner corner line.

[0045] like Figure 1 and Figure 2As shown, a concave groove 17 is provided on one side of the inner corner of the inner corner line body 1. The concave groove 17 can form a very clear process seam closing, which can achieve the purpose of decorating and beautifying the inner corner. And because the concave groove 17 is a strip-shaped slot structure, it can not only clearly separate the two walls constituting the inner corner, but also bring a very good visual experience. The concave groove 17 can play a very good decorative effect at the inner corner, which can ensure that the inner corner is very coordinated and beautiful. This helps to improve the aesthetics and grade of the inner corner decoration, and then helps to improve the quality of house decoration. And the concave groove 17 can be used for the installation of decorative objects or objects with other functions, which can facilitate the accurate positioning of the objects to be installed, thereby helping to improve the stability and accuracy of the installation and positioning of the relevant objects, which can ensure that the embedded inner corner line has high reliability. And this can also prevent the relevant objects from being too abrupt at the inner corner, so that more usage requirements can be met while ensuring the decorative effect. The embedded inner corner line has a very high applicability. After the concave groove 17 is adopted, the wall surfaces are completely separated from each other visually, which can create a visual sense of a suspended wall surface. Since the wall surfaces are separated from each other, when the wall surfaces are plastered, there is no need to worry about the difficulty of constructing the inner corner where the two surfaces meet, nor is there any need to worry about the blurred transition lines between the wall surfaces when the wall surfaces are painted with the same color, thereby avoiding the embarrassing illusion of not being able to distinguish the wall surfaces, and thus achieving a better decoration effect.

[0046] In actual use, the concave groove 17 is not only convenient for plaster storage, but also allows for accurate embedding of decorative strips (color strips, light strips). By storing plaster, it is convenient to store enough plaster at the inner corners, thereby reducing the probability of plaster at the inner corners falling off due to being too thin, which can enable the embedded inner corner line to maintain a good decorative effect for a long time. By embedding decorative strips, it can play a role in improving the aesthetics and quality of the building's inner corner decoration, thereby greatly improving the building's decorative quality, which helps to further improve the applicability of the embedded inner corner line.

[0047] like Figure 1 and Figure 2 As shown, the concave groove 17 is in a straight strip structure, and the two ends of the concave groove 17 respectively penetrate the two end surfaces of the inner corner line body 1. This not only facilitates molding and manufacturing, but also forms a very straight separation groove, which can play a very good role in separation and decoration.

[0048] like Figure 1 and Figure 2As shown, since the radial cross section of the inner corner wire body 1 is in an angle shape, an inner corner and an outer corner are formed at the transition between the inner and outer sides of the inner corner wire body 1. The outer corner of the inner corner wire body 1 is the corner on the outer side of the inner corner wire body 1, and the inner corner of the inner corner wire body 1 is the corner on the inner side of the inner corner wire body 1. In this way, a very reliable embedded inner corner wire can be formed.

[0049] like Figure 1 and Figure 2 As shown, the internal angle line body 1 is a profile structure. This not only facilitates the manufacture of the embedded internal angle line, but also ensures that the embedded internal angle line has a high structural strength, thereby helping to further improve the reliability and applicability of the embedded internal angle line.

[0050] like Figure 1 and Figure 2 As shown, the entire embedded internal corner line is a profile structure. This makes it easy to quickly form most of the structure of the embedded internal corner line, and only the through hole 14 cannot be formed together. After the profile is formed, the required embedded internal corner line can be quickly obtained by cutting and opening the through hole 14, which helps to improve the manufacturing efficiency of the embedded internal corner line, and this can also ensure that the embedded internal corner line has a high structural strength, thereby helping to further improve the reliability and applicability of the embedded internal corner line.

[0051] The embedded internal corner line is made of aluminum alloy or steel, which can ensure that the embedded internal corner line has high structural strength and durability, thereby helping to extend the service life of the embedded internal corner line.

[0052] The above embodiments are preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made thereto should fall within the protection scope of the present invention.
