Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a leveling strip. Background Art

[0002] At present, 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 punching: Hold a ruler close to the gypsum cake and punch out a rib perpendicular to the ground. Repeat the dotting and rib punching 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.

[0003] 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.

[0004] When the wall is very flat or poor, there will be gaps between the furniture and the wall, which will make the wall look uneven or tilted, or the furniture look crooked, which will bring a bad visual experience and affect the quality of the house. In addition, the gaps are easy for mosquitoes, dust, and debris to enter, so the inside of the furniture needs to be cleaned frequently to ensure indoor hygiene, which will cause inconvenience to indoor cleaning.

[0005] At the same time, when different decorative surfaces (different colors, different shades, different pictures, different materials, etc.) need to be made on the same wall, it is difficult to clearly separate the different decorative surfaces, and the visual perception of the existing separations between the decorative surfaces is very poor, which greatly affects the aesthetics and grade of the wall decoration, and thus easily affects the quality of house decoration. And when two adjacent non-coplanar decorative surfaces are painted with the same color, the transition lines between the two decorative surfaces will be very blurred. In many cases, it is easy to be unable to distinguish the transition lines between the two decorative surfaces, which will also affect the quality of house decoration.

[0006] In view of the above problems, it is very necessary to design a pre-buried leveling strip for separating decorative surfaces to improve the efficiency and quality of house decoration. Summary of the invention

[0007] The object of the present invention is to solve the above-mentioned problems and shortcomings, and to provide a pre-embedded leveling strip for separating decorative surfaces. The pre-embedded leveling strip has a reference convex strip and a groove strip portion. The reference convex strip can facilitate operators to quickly scrape out a flat and straight wall surface, thereby effectively improving the flatness and verticality of the wall surface leveling, and further greatly improving the efficiency and quality of the wall surface leveling. This can avoid gaps between furniture and the wall surface when the furniture is placed against the wall, which can bring a better visual experience and facilitate indoor cleaning. The reliability and applicability of the pre-embedded leveling strip are very good; through the arrangement of the groove strip portion, a clear dividing line with good visual effect can be formed when the pre-embedded leveling strip is used to separate different decorative surfaces, which helps to improve the aesthetics and grade of the wall surface decoration, thereby improving the quality of house decoration; and the overall structure of the pre-embedded leveling strip 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 leveling strip for separating decorative surfaces, characterized in that it comprises a leveling strip body, wherein a reference convex strip is arranged on the outer surface of the leveling strip body, and a groove strip portion in the same direction as the length direction of the leveling strip body is arranged on one side wall of the leveling strip body; a storage groove is arranged on the inner surface of the leveling strip 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; a plurality of through holes are arranged on the leveling strip body; each through hole penetrates the storage groove; a concave groove is arranged on the outer surface of the leveling strip body The concave-convex part is connected with a side wall of the reference convex strip, and the distance from the top surface of each convex point of the concave-convex part to the leveling strip body is gradually reduced in the direction away from the reference convex strip; it is ensured that the gypsum layer away from the reference convex strip is gradually thickened; the other side wall of the reference convex strip is connected with the side wall of the groove strip; an embedding groove is provided on the concave-convex part; the embedding groove can be used for embedding kraft paper; the concave-convex part is wavy; and each through hole is staggered from the concave-convex part.

[0010] Preferably, the groove wall of the embedding groove is in a C-shaped structure.

[0011] The beneficial effects of the present invention are as follows: (1) In the embedded leveling strip of the present invention, by setting an upper reference convex strip on the outer surface of the leveling strip body, the top surface of the reference convex strip can be made into a reference line for scraping plaster, so that when scraping plaster on the wall, there is a very reliable reference, which can facilitate the operator to scrape a flat and straight wall surface on the wall to avoid the wall surface from being skewed, which can greatly improve the decoration quality of the wall surface. The reliability and applicability of the embedded leveling strip are very good.

[0012] (2) When the pre-embedded leveling strip is used to level the wall, it is only necessary to install and position several pre-embedded leveling strips arranged side by side on the wall, and make the top surfaces of the reference convex strips on each pre-embedded leveling strip in the same vertical plane. This can quickly establish a very accurate and stable reference on the wall through the pre-embedded leveling strip. A very accurate and reliable reference can be established through the reference convex strip, and the accuracy of this reference is minimally affected by the workers. This 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 easier to make a wall with very high flatness and verticality. The pre-embedded leveling strip can greatly improve the quality of wall leveling. The application of the pre-embedded leveling strip 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 roughness like the ribs produced by punching. In addition, 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 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. This embedded leveling strip 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.

[0013] (3) The embedded leveling strip can easily create a wall with a very high degree of 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. 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 indoor hygiene can still be guaranteed, which helps to improve the convenience of indoor cleaning.

[0014] (4) By providing a groove portion in the same direction as the length direction of the leveling strip body on one side wall, when the embedded leveling strip is used to separate different decorative surfaces, a very clear dividing line can be formed through the groove portion. And because the groove portion has a groove structure, it can not only play a role in clearly separating different decorative surfaces, but also bring a very good visual experience. The groove portion can play a very good decorative effect at the separation of the decorative surfaces, which can ensure that the overall wall surface is very coordinated and beautiful. This helps to improve the aesthetics and grade of the wall decoration, and then helps to improve the quality of house decoration. The two decorative surfaces can be completely separated visually by the groove portion. Since the two decorative surfaces are separated from each other, there is no need to worry about the difficulty of construction at the intersection of the two surfaces when plastering the two decorative surfaces. Moreover, when two adjacent non-coplanar decorative surfaces are both painted with the same color, the transition lines between the two decorative surfaces can be avoided from being blurred. Even if the two adjacent decorative surfaces are coplanar, the transition lines can be ensured to be very clear, thereby making it easy to clearly distinguish the transition lines between the two decorative surfaces, thereby avoiding the embarrassing illusion of not being able to distinguish the two decorative surfaces, which also helps to improve the decoration quality of the house.

[0015] (5) The notches on the grooves can be used to install decorative objects or objects with other functions, which can facilitate 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 leveling strip has high reliability. This can also prevent the relevant objects from being too abrupt at the separation of the decorative surface, thereby meeting more usage requirements while ensuring the decorative effect. The embedded leveling strip has a very high applicability.

[0016] (6) At the same time, the overall structure of the embedded leveling strip is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of the three-dimensional structure of the embedded leveling strip in the present invention.

[0018] Figure 2 It is a schematic cross-sectional structure diagram of the embedded leveling strip in the present invention. DETAILED DESCRIPTION

[0019] like Figure 1 and Figure 2 As shown, the embedded leveling strip for separating decorative surfaces described in the present invention comprises a leveling strip body 1, wherein a reference convex strip 11 is arranged on the outer surface of the leveling strip body 1, and a groove portion 13 in the same direction as its length direction is arranged on one side wall of the leveling strip body 1.

[0020] In the embedded leveling strip of the present invention, a reference convex strip 11 is provided on the outer surface of the leveling strip body 1, so that the top surface of the reference convex strip 11 can be made into a reference line for scraping plaster, so that there is a very reliable reference when scraping plaster on the wall surface, thereby facilitating the workers to scrape a smooth and straight wall surface on the wall to avoid the wall surface from being skewed, which can greatly improve the decoration quality of the wall surface. The reliability and applicability of the embedded leveling strip are very good.

[0021] When the pre-embedded leveling strip is used to level the wall, it is only necessary to install and position several pre-embedded leveling strips arranged side by side on the wall, and make the top surface of the reference convex strips 11 on each pre-embedded leveling strip in the same vertical plane, so that a very accurate and stable reference can be quickly established on the wall through the pre-embedded leveling strip. 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 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 then it is easy to make a wall with very high flatness and verticality. The pre-embedded leveling strip can greatly improve the quality of wall leveling. The application of the pre-embedded leveling strip 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 11 as the reference, there will be no problem of roughness like the ribs produced by punching. In addition, the reference convex strip 11 is in the shape of a strip, 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 thus making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of wall leveling. The embedded leveling strip 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.

[0022] The embedded leveling strip 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, so that the indoor hygiene can still be guaranteed when the inside of the furniture is not cleaned frequently, which helps to improve the convenience of indoor cleaning.

[0023] By providing a groove portion 13 in the same direction as the length direction of the leveling strip body 1 on one side wall, when the embedded leveling strip is used to separate different decorative surfaces, a very clear dividing line can be formed through the groove portion 13. And because the groove portion 13 has a groove structure, it can not only play a role in obviously separating different decorative surfaces, but also bring a very good visual experience. The groove portion 13 can play a very good decorative effect at the separation of the decorative surfaces, which can ensure that the overall wall surface is very coordinated and beautiful. Thereby helping to improve the aesthetics and grade of the wall decoration, and then helping to improve the quality of house decoration. The two decorative surfaces can be completely separated in visual sense through the groove portion 13. Since the two decorative surfaces are separated from each other, there is no need to worry about the difficulty of construction at the intersection of the two surfaces when plastering the two decorative surfaces. Moreover, when two adjacent non-coplanar decorative surfaces are both painted with the same color, the transition lines between the two decorative surfaces can be avoided from being blurred. Even if the two adjacent decorative surfaces are coplanar, the transition lines can be ensured to be very clear, thereby making it easy to clearly distinguish the transition lines between the two decorative surfaces, thereby avoiding the embarrassing illusion of not being able to distinguish the two decorative surfaces, which also helps to improve the decoration quality of the house.

[0024] The slots on the groove portion 13 can be used to install decorative objects or objects with other functions, which can facilitate 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 leveling strip has high reliability. This can also prevent the relevant objects from being too abrupt at the separation of the decorative surface, thereby meeting more usage requirements while ensuring the decorative effect, and the embedded leveling strip has a very high applicability.

[0025] At the same time, the overall structure of the embedded leveling strip is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost.

[0026] like Figure 1 and Figure 2 As shown, the length direction of the reference convex strip 11 is consistent with the length direction of the leveling strip body 1. This not only ensures that the reference convex strip 11 has a longer length, but also facilitates the formation of a straight reference, thereby helping to further improve the applicability of the embedded leveling strip.

[0027] When installing the embedded leveling strip on the wall, first apply the leveling plaster mud to the leveling strip, and then press it onto the wall surface, so that the leveling strip body 1 is adhered to and / or buried in the plaster mud, and the reference convex strip 11 is exposed outside the plaster mud. Then, the light in the vertical plane projected by the infrared level is used as the light reference. Then, by pressing and knocking the leveling strip body 1 and / or the reference convex strip 11, the top surface of the reference convex strip 11 coincides with the light reference, which can build a very reliable reference through the reference convex strip 11, so that it is easy to make a wall surface with very high flatness and verticality.

[0028] The embedded leveling strip can be used not only for wall leveling and partition decoration, but also for ground leveling and partition decoration, and its applicability is very good.

[0029] like Figure 1 and Figure 2 As shown, the groove portion 13 can be used as a decorative groove left empty so as to leave a good decorative structure on the wall. At the same time, the groove portion 13 can also be used for accurately embedding decorative strips (color strips, light strips). By embedding decorative strips, the aesthetics and quality of wall decoration can be improved, thereby greatly improving the decorative quality of the wall. Such a structure helps to further improve the applicability of the embedded leveling strip.

[0030] like Figure 1 and Figure 2 As shown, the groove portion 13 is a straight strip structure. This can form a very straight dividing line through the groove portion 13, which can play a very good role in dividing and decorating. This can facilitate the production of straight transition lines, thereby improving the decoration effect in a minimalist decoration style, and further improving the aesthetics.

[0031] In the actual manufacturing process, the groove portion 13 can also be made into other shapes such as arc, wave, tooth, pattern, etc., which can meet more partition decoration requirements.

[0032] like Figure 1 and Figure 2 As shown, the groove portion 13 extends along the length direction of the leveling strip body 1, and the notch of the groove portion 13 faces the same direction as the top of the reference convex strip 11, that is, the notch of the groove portion 13 faces the outside of the wall, and the notch on the groove portion 13 penetrates to the end surfaces of both ends of the groove portion 13. This not only facilitates molding and manufacturing, but also forms a more intuitive decorative slot, which can bring a very good visual experience. The embedded leveling strip can further improve the aesthetics and grade of the decorative surface partition, thereby helping to further improve the quality of house decoration.

[0033] like Figure 1 and Figure 2 As shown, the radial cross section of the groove portion 13 is a concave structure. This not only enables the groove portion 13 to have a very simple structure, but also ensures that the groove portion 13 can well meet the needs of actual use, which helps to further improve the applicability of the embedded leveling strip.

[0034] like Figure 1 and Figure 2As shown, since the groove portion 13 is used for decoration or for mounting decorations, and the groove portion 13 is located on the side wall of the leveling strip body 1, there is no need to apply plaster on the groove portion 13. In this way, the thickness of the groove portion 13 will not affect the normal use of the reference convex strip 11, which can ensure that the embedded leveling strip can well meet the actual use requirements.

[0035] like Figure 1 and Figure 2 As shown, a storage groove 12 is provided on the inner surface of the leveling strip body 1. By providing the storage groove 12 on the inner surface of the leveling strip body 1, plaster or glue can be stored inside the leveling strip body 1 to ensure that there is sufficient plaster or glue between the pre-embedded leveling strip and the wall, thereby ensuring that the pre-embedded leveling strip can be installed on the wall very stably, which helps to further improve the reliability of the pre-embedded leveling strip.

[0036] like Figure 1 and Figure 2 As shown, the storage groove 12 penetrates the side wall of the leveling strip body 1 away from the groove portion 13. This makes it easy for excess plaster or glue to be discharged from the inner side of the embedded leveling strip to avoid affecting the normal installation and positioning of the embedded leveling strip, which makes it easier to install the embedded leveling strip more quickly, thereby helping to further improve the convenience and accuracy of the installation and positioning of the embedded leveling strip.

[0037] Before installation, first brush plaster or glue on part of the wall; then stick the embedded leveling strip on the plaster or glue, and squeeze the embedded leveling strip inwards, so that the excess plaster or glue will be squeezed out from the inner side of the embedded leveling strip.

[0038] like Figure 1 and Figure 2 As shown, the storage groove 12 also penetrates the end surfaces of both ends of the leveling strip body 1. This not only facilitates the storage of more plaster or glue, but also facilitates the molding of the storage groove 12, thereby facilitating the convenience of manufacturing.

[0039] like Figure 1 and 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 workers to apply plaster at the reference convex strip 11, thereby ensuring that the plastering can be carried out very smoothly, and further facilitating the improvement of the efficiency of wall decoration, which helps to further improve the applicability of the embedded leveling strip.

[0040] like Figure 1 and Figure 2As shown, the reference convex strip 11 is a cone structure with a wide inner side and a narrow outer side, which is not only convenient for 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 leveling strip.

[0041] like Figure 1 and Figure 2 As shown, the leveling strip body 1 is provided with a plurality of through holes 14. When installing the embedded leveling strip, the through holes 14 can facilitate the discharge of excess plaster or glue inside the embedded leveling strip, thereby avoiding excessive plaster or glue inside the embedded leveling strip, and then facilitating the quick fixation of the embedded leveling strip, which helps to further improve the installation efficiency of the embedded leveling strip. The through holes 14 can also facilitate the setting of plaster or glue penetrating the embedded leveling strip, thereby facilitating the more stable fixation of the embedded leveling strip on the wall, and then helping to further improve the stability and reliability of the installation and positioning of the embedded leveling strip.

[0042] like Figure 1 and Figure 2 As shown, the through holes 14 are arranged side by side along the length direction of the leveling strip body 1. This not only facilitates the formation of a reliable leveling strip body 1, but also reduces the influence of the through holes 14 on the structural strength of the leveling strip body 1, thereby ensuring that the leveling strip body 1 has high reliability.

[0043] like Figure 1 and Figure 2 As shown, each through hole 14 passes through the storage groove 12. This makes it easier to discharge excess plaster or glue, and further enhances the reliability and stability of the plaster or glue fixing the leveling strip body 1, thereby helping to further improve the reliability and applicability of the embedded leveling strip.

[0044] like Figure 1 and Figure 2 As shown, the outer surface of the leveling strip body 1 is provided with a concavo-convex portion 15, and the highest position of the concavo-convex portion 15 protruding outward is lower than the highest position of the reference convex strip 11 protruding outward. By providing the concavo-convex portion 15, the adhesion ability between the embedded leveling strip and the plaster can be improved, so that the embedded leveling strip can be stably buried in the wall, and then the plaster can be stably attached to the embedded leveling strip, which can greatly reduce the probability of cracking and falling of the plaster, which can facilitate the construction of a very reliable wall surface. The concavo-convex portion 15 can also enhance the structural strength of the embedded leveling strip. This helps to further improve the reliability of the embedded leveling strip.

[0045] like Figure 1 and Figure 2As shown, each through hole 14 is staggered with the concave-convex part 15. In this way, the concave-convex part 15 can be used to ensure that the pre-embedded leveling strip has a high structural strength, and the through hole 14 can be prevented from affecting the structural strength of the pre-embedded leveling strip, thereby ensuring that the pre-embedded leveling strip has a high reliability.

[0046] like Figure 1 and Figure 2 As shown, the concavoconvex part 15 is connected to the side wall of one side of the reference convex strip 11, and the distance from the top surface of each convex point 151 of the concavoconvex part 15 to the leveling strip body 1 is gradually reduced in the direction away from the reference convex strip 11. By making the concavoconvex part 15 connected to the reference convex strip 11, they can play a role of mutual reinforcement, which can not only enhance the reliability and stability of the connection between the reference convex strip 11 and the leveling strip body 1, but also improve the reliability and stability of the concavoconvex part 15, thereby helping to improve the structural strength of the embedded leveling strip, and further helping to further improve the reliability of the embedded leveling strip. By adopting the concavoconvex part 15 with the above thickness structure, it can be ensured that the gypsum layer away from the reference convex strip 11 is generally gradually thickened, and the concavoconvex part 15 itself facilitates 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 leveling strip.

[0047] like Figure 1 and Figure 2 As shown, the other side wall of the reference convex strip 11 is connected to the side wall of the groove portion 13. By connecting the reference convex strip 11 and the groove portion 13, they can achieve mutual reinforcement, which helps to further improve the reliability of the reference convex strip 11 and the groove portion 13, so that a pre-embedded leveling strip with better structural strength can be obtained, and then the reference established by the reference convex strip 11 can be ensured to be very reliable and stable, which helps to further improve the reliability and applicability of the pre-embedded leveling strip.

[0048] like Figure 1 and Figure 2 As shown, when the concavo-convex part 15 and the groove part 13 are both connected to the reference convex strip 11, the concavo-convex part 15 is connected to the side wall of the reference convex strip 11 away from the groove part 13. In this way, the concavo-convex part 15 and the groove part 13 are respectively connected to the side walls of the reference convex strip 11, and the three structures can play a more reliable reinforcement role, thereby helping to further improve the structural strength of the embedded leveling strip, and then ensure that the reference established by the reference convex strip 11 is more reliable, which can further improve the reliability and applicability of the embedded leveling strip.

[0049] like Figure 1 and Figure 2As shown, the concave-convex part 15 is provided with an embedding groove 16. The embedding groove 16 can be used for embedding kraft paper, so that the kraft paper can be positioned on the pre-embedded leveling strip stably and accurately, so that a more gentle transition can be formed between the pre-embedded leveling strip and the gypsum, and the pre-embedded leveling strip can be more reliably connected with the gypsum, which helps to further improve the reliability of the pre-embedded leveling strip. In addition, this can reduce the impact of thermal expansion and contraction and collision on the pre-embedded leveling strip, so as to avoid cracking of the gypsum at the side of the pre-embedded leveling strip in these cases, so as to ensure that the wall surface maintains a good decorative effect for a long time, which helps to further improve the reliability and applicability of the pre-embedded leveling strip. By providing the embedding groove 16 on the concave-convex portion 15, it can not only reduce the impact on the structural strength of the leveling strip body 1, but also make it easier for the kraft paper to be pasted on the concave-convex portion 15, which can facilitate the kraft paper to be limited by the concave-convex portion 15, thereby facilitating the reliability of the kraft paper installation and positioning, thereby ensuring that the embedded leveling strip has a very high reliability.

[0050] like Figure 1 and Figure 2 As shown, the embedding groove 16 is a strip groove, and the two ends of the embedding groove 16 are respectively penetrated to the two end surfaces of the leveling strip 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 16.

[0051] like Figure 1 and Figure 2 As shown, the groove wall of the embedding groove 16 is in a C-shaped structure. This can make the embedding groove 16 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 leveling strip.

[0052] During installation, one end of the kraft paper is embedded in the embedding groove 16, and the other end of the kraft paper is away from the reference convex strip 11, and the kraft paper is covered on the side of the embedded leveling strip. This can meet the installation requirements.

[0053] like Figure 1 and Figure 2 As shown, the concavoconvex part 15 is wavy. The structure of the concavoconvex part 15 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 leveling strip.

[0054] like Figure 1 and Figure 2 As shown, the leveling strip body 1 is a strip-shaped structure, which can ensure that the pre-embedded leveling strip has high reliability and facilitate the manufacture and embedding of the pre-embedded leveling strip, thereby ensuring that the pre-embedded leveling strip has high applicability.

[0055] like Figure 1and Figure 2 As shown, the embedded leveling strip is a profile structure. This makes it easy to quickly form most of the structure of the embedded leveling strip, and only the through hole 14 cannot be formed together. After the profile is formed, the required embedded leveling strip can be quickly obtained by cutting and opening the through hole 14, which helps to improve the manufacturing efficiency of the embedded leveling strip, and this can also ensure that the embedded leveling strip has a high structural strength, thereby helping to further improve the reliability and applicability of the embedded leveling strip.

[0056] The pre-embedded leveling strip is made of aluminum alloy or steel, which can ensure that the pre-embedded leveling strip has high structural strength and durability, thereby helping to extend the service life of the pre-embedded leveling strip.

[0057] 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.
