Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a pre-buried ceiling line. Background Art

[0002] At present, the intersection of the wall and the ceiling is called "yin angle" in the decoration jargon. When constructing at this location, it is difficult for construction workers to make the "yin angle" straight. Usually it is a curved line, and it is difficult to make the angles of the "yin angle" uniform. In the minimalist decoration style, it seriously affects the decoration effect and reduces the beauty.

[0003] At the same time, in order to level the wall, most people use rib leveling. Among them, the steps of rib leveling are as follows: Dotting: Use gypsum cakes to find base points on the wall, connect the points and connect them vertically 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 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 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 vertical wall that constitutes the ceiling line is very poor or relatively poor, it is easy to affect the flatness and straightness of the ceiling line, which can easily lead to poor flatness, skewness, inconsistent angles at both ends, etc. of the ceiling line. And when the flatness of the wall surface is very poor or relatively poor, gaps are likely to appear between the ceiling board placed against the wall and the wall surface, and between the furniture and the wall surface, which can easily make the wall surface appear uneven and tilted, or the ceiling board appear skewed and the furniture tilted, which can easily bring a poor visual experience and affect the improvement of the house grade. And the gaps on the back of the furniture are easy to enter mosquitoes, dust, debris, etc., and it is necessary to clean the inside of the furniture 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 ceiling line to improve the construction efficiency and quality of ceiling panels and walls. 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 ceiling line, which comprises a limiting strip and an embedding strip, and a reference convex strip is arranged on the embedding strip. The limiting strip can facilitate accurate positioning of the ceiling board, and the embedding strip can achieve the function of embedding positioning, thereby ensuring the stability of the installation and positioning of the pre-embedded ceiling line; through the setting of the reference convex strip, not only the pre-embedded ceiling line can be accurately installed, but also the vertical wall surface constituting the ceiling line can be scraped very flat and straight, thereby ensuring that the vertical wall surface constituting the ceiling line has a very high flatness and verticality, and then a very standard and beautiful ceiling line can be made, which can facilitate improving the quality of building decoration. When the ceiling panels and furniture are placed against the wall, gaps are avoided between the ceiling panels and the wall, and between the furniture and the wall, which can bring a better visual experience and facilitate indoor cleaning. The reliability and applicability of the pre-buried ceiling line are very good, and the overall structure of the pre-buried ceiling line is very simple, and the difficulty and cost of manufacturing it are very low.

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

[0009] A pre-buried ceiling line, characterized in that it comprises a limit strip and an embedded strip, wherein the limit strip and the embedded strip are arranged transversely, and the rear side of the limit strip is connected to the upper side of the embedded strip, and a reference convex strip is arranged on the front surface of the embedded strip; 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; the limit strip and the embedded strip are perpendicular to each other; a transversely extending concave strip groove is provided on the rear lower surface of the limit strip; a concave-convex part is arranged in the embedded strip, and the highest height of the concave-convex part protruding forward is lower than the height of the reference convex strip protruding forward degree; the concave-convex part is wavy; the height of each convex point of the concave-convex part protruding forward gradually decreases from top to bottom; it is ensured that the gypsum layer away from the reference convex strip is generally gradually thickened; the concave-convex part is provided with an embedding groove; the embedding groove can be used for embedding kraft paper; a storage groove is provided on the rear surface of the embedded strip; a limiting groove is provided on the front lower surface of the limit strip; a plurality of longitudinal through holes are provided on the embedded strip; each through hole is staggered from the concave-convex part; each through hole also penetrates the storage groove; a clearance gap is provided on the outer corner of the connection between the limit strip and the embedded strip.

[0010] Preferably, the limiting strip and the embedding strip are an integrated profile structure.

[0011] Beneficial effects of the present invention: (1) The embedded ceiling line of the present invention includes a limit strip and an embedded strip. Since the limit strip and the embedded strip are arranged horizontally, and the rear side of the limit strip is connected to the upper side of the embedded strip, the limit strip can accurately and stably limit the ceiling board, which helps to improve the accuracy and stability of the installation and positioning of the end of the ceiling board. The reliability of the embedded ceiling line is very good.

[0012] (2) The embedded strip can achieve the embedded positioning function, thereby ensuring the stability and reliability of the installation and positioning of the embedded ceiling line. By setting an upper reference convex strip on the front surface of the embedded strip. It can not only be used as a reference for installing the embedded ceiling line, but also as a reference line for scraping the vertical wall that constitutes the ceiling line. So that when scraping plaster on the vertical wall, there is a very reliable reference, which can facilitate the operator to manually scrape a flat and straight vertical wall on the wall to avoid poor flatness and skewness on the vertical wall. This can ensure that the vertical wall that constitutes the ceiling line has a very high flatness and verticality, so as to avoid the skewness of the ceiling line, inconsistent angles at both ends, etc. The use of the embedded ceiling line can greatly improve the decoration quality of the building, and the applicability of the embedded ceiling line is very strong.

[0013] (3) The embedded ceiling line can not only make a reliable ceiling line, but also be used to level the vertical wall that constitutes the ceiling line. A very accurate and reliable benchmark can be established through the reference convex strip, and the accuracy of this benchmark is minimally affected by workers, which can greatly reduce the error of vertical wall leveling and ensure that the benchmark has a very high accuracy, thereby greatly improving the accuracy of vertical wall leveling construction, and thus making it easy to make a vertical wall with very high flatness and verticality. It can make it easy to make a very standard and beautiful ceiling line. The embedded ceiling line can greatly improve the quality of vertical wall leveling. The application of the embedded ceiling line can directly save the tedious "dotting" operation in the existing rib leveling, which can greatly reduce the difficulty of vertical wall leveling and greatly improve the efficiency of vertical wall leveling.

[0014] 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 making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of vertical wall leveling. This embedded ceiling 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.

[0015] (4) The pre-buried ceiling line can be used to easily create a wall with a very high degree of flatness and verticality, so that when the ceiling board and furniture are placed against the wall, gaps between the ceiling board and the wall, and between the furniture and the wall can be avoided, so that the wall will not appear uneven or tilted, and the ceiling board will not appear crooked or the furniture will not fall, 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, and it can also facilitate the improvement of the reliability and applicability of the pre-buried ceiling line.

[0016] (5) At the same time, the overall structure of the embedded ceiling line is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 and Figure 2 As shown, a pre-buried ceiling line described in the present invention comprises a limiting strip 1 and an embedding strip 2, wherein the limiting strip 1 and the embedding strip 2 are arranged horizontally, and the rear side of the limiting strip 1 is connected to the upper side of the embedding strip 2, and a reference convex strip 21 is provided on the front surface of the embedding strip 2.

[0022] The embedded ceiling line of the present invention comprises a limit strip 1 and an embedding strip 2. Since the limit strip 1 and the embedding strip 2 are arranged horizontally, and the rear side of the limit strip 1 is connected to the upper side of the embedding strip 2, the limit strip 1 can accurately and stably limit the ceiling board, which helps to improve the accuracy and stability of the installation and positioning of the end of the ceiling board, and the reliability of the embedded ceiling line is very good.

[0023] The embedded strip 2 can achieve the embedded positioning effect, thereby ensuring the stability and reliability of the embedded ceiling line installation and positioning. After the embedded strip 2 is installed in an embedded manner, the exposure amount of the embedded ceiling line can also be reduced, thereby reducing the impact of the embedded ceiling line on the aesthetics of the house decoration. By setting the upper reference convex strip 21 on the front surface of the embedded strip 2. It can not only be used as a reference for installing the embedded ceiling line, but also as a reference line for scraping the vertical wall surface that constitutes the ceiling line. So that when scraping plaster on the vertical wall surface, there is a very reliable reference, so that it is convenient to manually scrape a flat and straight vertical wall surface on the wall to avoid the vertical wall surface having poor flatness and skewness. This can ensure that the vertical wall surface that constitutes the ceiling line has a very high flatness and verticality, so as to avoid the ceiling line from being skewed, the angles at both ends being inconsistent, etc. The use of the embedded ceiling line can greatly improve the decoration quality of the building, and the applicability of the embedded ceiling line is very strong.

[0024] The embedded ceiling line can not only make a reliable ceiling line, but also be used to level the vertical wall that constitutes the ceiling line. A very accurate and reliable benchmark can be established through the reference convex strip 21, and the accuracy of this benchmark is minimally affected by workers, which can greatly reduce the error of vertical wall leveling and ensure that the benchmark has a very high accuracy, thereby greatly improving the accuracy of vertical wall leveling construction, and then it is easy to make a vertical wall with very high flatness and verticality, which can make it easy to make a very standard and beautiful ceiling line. The embedded ceiling line can greatly improve the quality of vertical wall leveling. The application of the embedded ceiling line can directly save the cumbersome "dotting" operation in the existing rib leveling, which can greatly reduce the difficulty of vertical wall leveling and greatly improve the efficiency of vertical wall leveling.

[0025] By using the reference convex strip 21 as a reference, there will be no problem of roughness like the ribs produced by punching, and the reference convex strip 21 is in strip shape, which can greatly reduce the friction between the ruler and the reference convex strip 21 during filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and then making it easier to scrape and level, which also helps to improve the efficiency and quality of vertical wall leveling. The embedded ceiling 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.

[0026] The embedded ceiling line can easily create a wall with very high flatness and verticality, so that when the ceiling board and furniture are placed against the wall, gaps between the ceiling board and the wall, and between the furniture and the wall can be avoided, so that the wall will not appear uneven or tilted, and the ceiling board will not appear crooked or the furniture will fall, 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, and it can also facilitate the improvement of the reliability and applicability of the embedded ceiling line.

[0027] At the same time, the overall structure of the embedded ceiling line is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost.

[0028] like Figure 1 and Figure 2 As shown, the length direction of the reference convex strip 21 is consistent with the length direction of the embedded strip 2. This not only ensures that the reference convex strip 21 has a longer length, but also facilitates the formation of a straight reference, so that it is more convenient to refer to, and it also facilitates the molding of the reference convex strip 21, thereby helping to further improve the applicability of the embedded ceiling line.

[0029] like Figure 1 and Figure 2 As shown, the top surface of the reference convex strip 21 is an arched arc surface 211. This not only serves as a very good reference, but also further reduces the resistance of plastering on the reference convex strip 21, so as to facilitate the workers to apply plaster at the reference convex strip 21, thereby ensuring that the plastering can be carried out very smoothly, and further facilitating the improvement of the efficiency of ceiling decoration, which helps to further improve the applicability of the embedded ceiling line.

[0030] like Figure 1 and Figure 2 As shown, the reference convex strip 21 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 21 has a high structural strength, thereby helping to improve the reliability and applicability of the embedded ceiling line.

[0031] When actually installing the embedded ceiling line, several other leveling strips with reference convex strips can be embedded on the vertical wall constituting the ceiling line. In this way, a very reliable reference surface can be established by making the reference convex strip 21 on the embedded ceiling line and other reference convex strips in the same vertical plane, and in the process of adjusting the embedded ceiling line, the limit strip 1 is adjusted to a horizontal arrangement state. This allows the gypsum mud to be scraped based on this reference surface when filling the gypsum mud, so that it is easy to scrape out a vertical wall surface with very high flatness and verticality, and then it is easy to build a very straight and beautiful ceiling line.

[0032] like Figure 1 and Figure 2 As shown, a concave groove 11 extending laterally is provided on the rear lower surface of the limit strip 1. The concave groove 11 can form a very clear process seam closing, which can achieve the purpose of decorating and beautifying the ceiling line. And because the concave groove 11 is a strip-shaped slot structure, it can not only clearly separate the ceiling board and the vertical wall, but also bring a very good visual experience. The concave groove 11 can have a very good decorative effect at the ceiling line, which can ensure that the ceiling line is very coordinated and beautiful. Thereby, it helps to improve the beauty and grade of the ceiling line decoration, and then helps to improve the quality of house decoration. And the concave groove 11 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 ceiling line has high reliability and applicability. And this can also prevent the relevant objects from being too abrupt at the ceiling line, so that more usage requirements can be met while ensuring the decorative effect, and the embedded ceiling line has a very high applicability. The concave groove 11 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 concave groove 11 can also be accurately embedded for decorative strips, color strips and light strips. By embedding decorative strips, the aesthetics and quality of wall decoration can be improved, so that the decorative quality of the wall can be greatly improved. Such a structure helps to further improve the applicability of the embedded ceiling line. The concave groove 11 can make the wall and the ceiling surface completely separated in visual sense, which can create a visual sense of a suspended ceiling. Since the wall and the ceiling are separated from each other, there is no need to worry about the difficulty of "yin angle" construction at the intersection of the two surfaces when plastering the wall and the ceiling. And when both the wall and the ceiling are painted with the same color, the transition line between the ceiling and the wall can be avoided from being blurred, thereby avoiding the embarrassing illusion of not being able to distinguish between the ceiling and the wall, and thus achieving a better decoration effect.

[0033] like Figure 1 and Figure 2As shown, the limit strip 1 and the embedded strip 2 are both slat structures, and the limit strip 1 and the embedded strip 2 are perpendicular to each other. The limit strip 1 and the embedded strip 2 together constitute a ceiling line body with a radial cross-section of 90 degrees. This can easily make the "inner angle" at the intersection of the ceiling surface and the wall surface 90 degrees, solving the problem that it is difficult to achieve a standard 90-degree angle at the inner corner during construction. In this way, it can ensure that the embedded ceiling line has high reliability and can also ensure that the embedded ceiling line can meet the installation of most ceiling panels, thereby ensuring that the embedded ceiling line has high applicability.

[0034] like Figure 1 and Figure 2 As shown, the concave groove 11 is in a straight strip structure, and the two ends of the concave groove 11 are respectively penetrated to the two end surfaces of the limiting strip 1, and the concave groove 11 is opened close to the inner corner of the connection between the limiting strip 1 and the embedded strip 2. This not only facilitates molding and manufacturing, but also forms a very straight concave groove 11, which can play a very good decorative role.

[0035] like Figure 1 and Figure 2 As shown, the embedded strip 2 is provided with a concave-convex portion 22, and the maximum height of the concave-convex portion 22 protruding forward is lower than the height of the reference convex strip 21 protruding forward. The provision of the concave-convex portion 22 can improve the adhesion between the embedded ceiling line and the gypsum, thereby ensuring that the gypsum can be stably attached to the embedded ceiling line, which can greatly reduce the probability of cracking and falling off of the gypsum, which can facilitate the construction of a very reliable wall surface, and the reliability of the embedded ceiling line is very high.

[0036] like Figure 1 and Figure 2 As shown, the concave-convex part 22 is wavy. The structure of the concave-convex part 22 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 ceiling line.

[0037] like Figure 1 and Figure 2As shown, the concave-convex part 22 is connected to the lower side wall of the reference convex strip 21, and the height of each convex point 221 of the concave-convex part 22 protruding forward is gradually reduced from top to bottom. By connecting the concave-convex part 22 with the reference convex strip 21, they can play a role of mutual reinforcement, which not only enhances the reliability and stability of the connection between the reference convex strip 21 and the embedded strip 2, but also improves the reliability and stability of the concave-convex part 22, thereby helping to improve the structural strength of the pre-embedded ceiling line, and further helping to further improve the reliability of the pre-embedded ceiling line. By adopting the concave-convex part 22 with the above thickness structure, it can be ensured that the gypsum layer away from the reference convex strip 21 is generally gradually thickened, and the concave-convex part 22 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 pre-embedded ceiling line. Furthermore, by connecting the concave-convex portion 22 with the reference convex strip 21 , the embedded ceiling 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 22 is provided with an embedding groove 23. The embedding groove 23 can be used for embedding kraft paper, so that the kraft paper can be positioned on the embedded ceiling line stably and accurately, so that a more gentle transition can be formed between the embedded ceiling line and the gypsum, and the embedded ceiling line can be more reliably connected to the gypsum, which helps to further improve the reliability of the embedded ceiling line. In addition, this can reduce the impact of thermal expansion and contraction and collision on the embedded ceiling line, so as to avoid cracking of the gypsum at the side of the embedded ceiling line 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 embedded ceiling line. By providing the embedding groove 23 on the concave-convex part 22. In this way, the kraft paper will be attached to the concave-convex part 22, which can limit the kraft paper through the concave-convex part 22, so that the reliability of the installation and positioning of the kraft paper can be improved, and the embedded ceiling line can also be ensured to have a very high reliability.

[0039] like Figure 1 and Figure 2 As shown, the embedding groove 23 is a strip groove, and the two ends of the embedding groove 23 are respectively penetrated to the two end surfaces of the embedding strip 2. This can not only facilitate the formation of a more reliable embedding effect, but also facilitate the manufacturing and processing of the embedding groove 23.

[0040] like Figure 1 and Figure 2 As shown, the groove wall of the embedding groove 23 is in the shape of a letter C. In this way, the embedding groove 23 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 ceiling line.

[0041] During installation, one end of the kraft paper is embedded in the embedding groove 23, and the other end of the kraft paper is away from the limit strip 1, and the kraft paper covers the lower side of the embedded ceiling line. This can meet the installation requirements.

[0042] like Figure 1 and Figure 2 As shown, a storage groove 24 is provided on the rear surface of the embedded strip 2. The storage groove 24 can be used to store plaster or glue to ensure that there is sufficient plaster or glue between the embedded ceiling line and the wall, so that the embedded ceiling line can be installed on the wall very stably, which helps to further improve the reliability of the embedded ceiling line.

[0043] like Figure 1 and Figure 2 As shown, the storage groove 24 penetrates the lower surface of the embedded strip 2. This makes it easy for excess plaster or glue to be discharged from the lower side of the embedded ceiling line to avoid them affecting the normal installation and positioning of the embedded ceiling line, which makes it easy to install the embedded ceiling line more quickly, thereby helping to further improve the convenience and accuracy of the installation and positioning of the embedded ceiling line.

[0044] Before installation, first apply plaster or glue on the vertical wall or embedded ceiling line; then adhere the embedded ceiling line to the vertical wall, and press the embedded ceiling line inward, so that the excess plaster or glue will be squeezed out from the inner side of the embedded ceiling line. Then use the light projected by the infrared level as a reference for adjusting the reference convex strip 21. Then, by pressing and tapping the embedded strip 2 and / or the reference convex strip 21, and referring to the light projected by the infrared level, adjust the top surface of the reference convex strip 21 to the virtual vertical plane, which can build a very reliable reference through the reference convex strip 21, 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 ceiling line.

[0045] like Figure 1 and Figure 2 As shown, the storage groove 24 also penetrates the end surfaces of both ends of the embedding strip 2. This not only facilitates the storage of more plaster or glue, but also facilitates the molding of the storage groove 24, thereby facilitating the convenience of manufacturing.

[0046] like Figure 1 and Figure 2 As shown, a limiting groove 12 is provided on the front lower surface of the limiting strip 1. The limiting groove 12 is provided on the front lower surface of the limiting strip 1, which allows the end of the ceiling plate to be accurately embedded, which can facilitate the ceiling plate to have a very accurate and stable limiting effect, and can facilitate the installation and removal of the ceiling plate, thereby helping to further improve the reliability and applicability of the embedded ceiling line.

[0047] like Figure 1 and Figure 2 As shown, a toothed surface 121 is provided on the upper groove wall of the limiting groove 12. This can enhance the friction force so that the ceiling board can be embedded in the limiting groove 12 very stably, which helps to further improve the reliability of the embedded ceiling line.

[0048] like Figure 1 and Figure 2 As shown, the embedded strip 2 is provided with a plurality of longitudinal through holes 25. When installing the embedded ceiling line, the through holes 25 can facilitate the discharge of excess plaster or glue on the inner side of the embedded ceiling line, thereby avoiding excessive plaster or glue on the inner side of the embedded ceiling line, and then facilitating the quick fixation of the embedded ceiling line, which helps to further improve the installation efficiency of the embedded ceiling line. The through holes 25 can also facilitate the setting of plaster or glue running through the embedded ceiling line, thereby facilitating the more stable fixation of the embedded ceiling line on the wall, and then helping to further improve the stability and reliability of the installation and positioning of the embedded ceiling line. By opening the through holes 25, when the position of the reference convex strip 21 on the embedded ceiling line is adjusted by pressing, it is convenient for the excess plaster mud on the inner side to pass through, thereby avoiding the excess plaster mud affecting the adjustment of the embedded ceiling line, and such a structure helps to improve the convenience of adjusting the embedded ceiling line.

[0049] like Figure 1 and Figure 2 As shown, each through hole 25 is staggered with the concave-convex portion 22, and each through hole 25 is located below the concave-convex portion 22. In this way, the concave-convex portion 22 can be used to ensure that the pre-buried ceiling line has a high structure, and the through holes 25 can be prevented from affecting the structural strength of the pre-buried ceiling line, thereby ensuring that the pre-buried ceiling line has high reliability.

[0050] like Figure 1 and Figure 2 As shown, each through hole 25 also penetrates the storage groove 24. This makes it easier to discharge excess plaster or glue, and further enhances the reliability and stability of the plaster or glue fixing the embedding strip 2.

[0051] like Figure 1 As shown, the through holes 25 are arranged side by side along the length direction of the embedding bar 2. This not only facilitates the formation of a reliable embedding bar 2, but also reduces the influence of the through holes 25 on the structural strength of the embedding bar 2, thereby ensuring that the embedding bar 2 has high reliability.

[0052] like Figure 1 and Figure 2As shown, a clearance gap 26 is provided on the outer corner of the connection between the limit strip 1 and the embedding strip 2. In this way, the outer corner of the embedded ceiling line can be staggered from the wall defects or other defects, thereby reducing the impact of the wall defects on the installation of the embedded ceiling line, which can facilitate the improvement of the convenience, stability and reliability of the installation and positioning of the embedded ceiling line. In some use cases, the clearance gap 26 can also be used to store plaster or glue to ensure that there is sufficient plaster or glue between the embedded ceiling line and the wall, thereby ensuring that the embedded ceiling line can be installed on the wall very stably, which helps to further improve the reliability of the embedded ceiling line. And after adopting the clearance gap 26, the installation of the embedded ceiling line can be satisfied without additional treatment of the wall defects, which helps to improve the convenience and efficiency of installation.

[0053] like Figure 1 and Figure 2 As shown, the clearance gap 26 is in a right angle shape, which not only enables the clearance gap 26 to have a better clearance effect, but also facilitates the opening of the clearance gap 26, thereby helping to further improve the reliability and applicability of the embedded ceiling line.

[0054] like Figure 3 and Figure 4 As shown, when the embedded ceiling line is used, first fix the horizontally extending positioning strip 20 on the upper side of the wall 10; then scrape the plaster 30 on the wall surface below the positioning strip 20 or scrape the plaster 30 on the embedded strip 2; then arrange the embedded ceiling line on the bottom surface of the positioning strip 20, and make the embedded strip 2 adhere to the wall 10 through the plaster 30; then press the reference convex strip 21 to be in a virtual vertical plane, and when other leveling strips with reference convex strips are installed on the wall 10, make all the reference convex strips The strips are all in the virtual vertical plane; then, kraft paper (not shown) is embedded in the embedding groove 23, and the kraft paper covers the lower end of the embedding strip 2; then, plaster is scraped on the front side of the embedding strip 2 and the kraft paper, and the reference convex strip 21 is used as a reference, so that a vertical wall surface 40 with high flatness and good verticality can be scraped out; after the plaster hardens, a screw 50 is arranged in the limiting groove 12, and the threaded end of the screw 50 passes through the limiting strip 1 and is screwed to the positioning strip 20; finally, the end of the ceiling board 60 is embedded in the limiting groove 12. In this way, the use requirements of the pre-embedded ceiling line can be well met.

[0055] The installation, placement and use method of the embedded ceiling cable is not limited to the above-mentioned one. In actual use, other installation methods can also be used for installation.

[0056] like Figure 1 and Figure 2As shown, the limit strip 1 and the embedding strip 2 are an integrated profile structure, which not only facilitates the manufacture of the embedded ceiling line, but also ensures that the embedded ceiling line has a high structural strength, thereby helping to further improve the reliability and applicability of the embedded ceiling line.

[0057] like Figure 1 and Figure 2 As shown, the entire embedded ceiling line is a profile structure. This makes it easy to quickly form most of the structure of the embedded ceiling line, and only the through hole 25 cannot be formed together. After the profile is formed, the required embedded ceiling line can be quickly obtained by cutting and opening the through hole 25, which helps to improve the manufacturing efficiency of the embedded ceiling line, and this can also ensure that the embedded ceiling line has a high structural strength, thereby helping to further improve the reliability and applicability of the embedded ceiling line.

[0058] The pre-buried ceiling wire is made of aluminum alloy or steel, which can ensure that the pre-buried ceiling wire has high structural strength and durability, thereby helping to extend the service life of the pre-buried ceiling wire.

[0059] 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.
