Description

Technical Field

[0001] The invention relates to the technical field of building decoration, and in particular to a ceiling corner anti-cracking structure and a construction method thereof. Background Art

[0002] In building decoration projects, gypsum board ceilings are widely used in interior decoration. They are light, beautiful and easy to construct, and are widely welcomed. However, gypsum board ceilings are prone to cracking during use, especially at corners, which seriously affects the appearance and service life. Traditional anti-cracking methods such as using reinforcing ribs or mesh cloth, although effective, are complex and costly to construct, and have limited application effects at corners.

[0003] In the Chinese patent document with the authorization announcement number CN206189711U, a crack-proof gypsum board ceiling is disclosed, in which the gypsum board is laid on the outer surface of the light steel keel frame and fixedly connected to the light steel keel by self-tapping bolts. After the gypsum board is installed, the mesh cloth is pasted on the surface of the gypsum board, and the edge of the mesh cloth is fixedly connected to the light steel keel. The fixed connection can be achieved by using iron wire or nylon rope to fix the mesh cloth to the side keel of the light steel keel; to further reinforce the gypsum board, the surface of the gypsum board is pasted with alkali-resistant tape to form an alkali-resistant tape layer. Then, kraft paper is pasted on the alkali-resistant tape layer and located at the gap position between two adjacent gypsum boards for reinforcement. Then, a steel mesh is attached to the outer surface of the gypsum board and fixedly connected to the side keel of the light steel keel, that is, the four sides of the steel mesh are tightened on the side keel by steel wire to complete the fixed connection.

[0004] The anti-cracking gypsum board ceiling in the above-mentioned public documents adopts the method of laying mesh cloth, alkali-resistant tape and wire mesh on the outer side of the gypsum ceiling board as a whole to prevent the cracking of the gypsum board ceiling. Although it can also achieve certain effects, the construction steps are complicated and the construction cost is high. In particular, it is not effective in preventing cracking at corners, and further improvement is needed. Summary of the invention

[0005] The purpose of the present invention is to provide a ceiling corner anti-cracking structure and a construction method thereof, which has simple structure, convenient construction, low construction cost and significant anti-cracking effect on the ceiling corners.

[0006] In order to solve the above technical problems, the embodiments of the present invention provide a technical solution as follows:

[0007] A ceiling corner anti-cracking structure comprises a first ceiling board as an inner layer of the corner and a second ceiling board as an outer layer of the corner, wherein elastic tape, mesh cloth and kraft paper are sequentially attached to the outer side of the corner, self-tapping screws are arranged between the mesh cloth and the elastic tape, and the self-tapping screws sequentially pass through the elastic tape, the second ceiling board and the first ceiling board to fix the three together.

[0008] Furthermore, the mesh cloth is bonded to the outer layer of the elastic tape, and the mesh cloth extends around more than the elastic tape.

[0009] Furthermore, the kraft paper is pasted on the outer layer of the mesh cloth, and the edge of the mesh cloth is exposed outside the kraft paper.

[0010] Furthermore, the outer layer of the kraft paper is coated with a glue layer.

[0011] In order to solve the above technical problems, the embodiments of the present invention further provide a technical solution:

[0016] Step S4: Attach the kraft paper to the mesh cloth, and use a tool to compact the kraft paper to remove bubbles and gaps.

[0017] Further, the step S3 includes evenly applying glue on the surface and surrounding of the elastic tape, wherein the glue coverage is slightly larger than the size of the tape, and then attaching the mesh cloth to the glue coverage area, wherein the edge of the mesh cloth is tightly fitted to the second ceiling panel.

[0018] Furthermore, step S4 includes evenly applying glue on the surface of the mesh cloth, attaching kraft paper to the outer layer of the mesh cloth coated with glue, compacting the kraft paper with a scraper or a roller to remove bubbles and gaps, and the edge of the mesh cloth is exposed outside the kraft paper.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection in the claims of the present application can be implemented.

[0028] like Figure 1-2 As shown, in modern decoration, for aesthetic and practical considerations, gypsum boards, wood boards and other ceiling panels are often used for ceiling decoration. For example, when installing a central air conditioner or a duct machine, it is necessary to wrap the air conditioner indoor unit with a ceiling, and reserve holes for the air conditioner outlet 100 and the air conditioner return air outlet 200. Due to process limitations, the reserved holes of the ceiling or different planes often need to be spliced ​​or overlapped for construction. Due to the structural stress itself and the structural deformation of the ceiling panel material under the influence of ambient temperature and humidity, cracks are very likely to occur at the corners. An embodiment of the present invention relates to a ceiling corner anti-cracking structure, including a first ceiling panel 10 as an inner layer of the corner and a second ceiling panel 20 as an outer layer of the corner, wherein an elastic tape 40, a mesh cloth 50, and kraft paper 60 are sequentially attached to the outer side of the corner, and a self-tapping screw 30 is provided between the mesh cloth 50 and the elastic tape 40, and the self-tapping screw 30 passes through the elastic tape 40, the second ceiling panel 20 and the first ceiling panel 10 in sequence to fix the three together.

[0029] In an exemplary embodiment, the mesh cloth 50 is bonded to the outer layer of the elastic tape 40, and the mesh cloth 50 extends beyond the elastic tape 40. During construction, special glue is evenly applied to the surface of the elastic tape 40 to ensure that the glue coverage is slightly larger than the size of the tape. The mesh cloth 50 is adhered to the glue area to completely cover the elastic tape and the self-tapping screws 30. The kraft paper 60 is pasted on the outer layer of the mesh cloth 50, and the edge of the mesh cloth 50 is exposed outside the kraft paper 60. Glue is coated between the kraft paper 60 and the mesh cloth 50. After the kraft paper 60 is pasted on the mesh cloth 50, a scraper or a roller is used to compact the kraft paper 60 to eliminate bubbles and gaps, so as to keep the kraft paper 60 and the mesh cloth 50 flat and in contact. Preferably, the outer layer of the kraft paper 60 is coated with a glue layer to facilitate the kraft paper 60 to fit more closely with the ceiling board, and to increase the adhesion between the kraft paper 60 and the exterior layer 70.

[0030] like Figure 1-3 As shown, in order to solve the technical problem proposed by the present invention, the embodiment of the present invention also relates to a construction method of a ceiling corner anti-cracking structure, comprising the following steps:

[0031] Step S1: remove dust and debris from the ceiling corner; the ceiling corner is composed of a first ceiling board 10 at the inner corner layer and a second ceiling board 20 at the outer corner layer, the length of the corner is measured and marked, and materials of corresponding length are prepared, the materials include elastic tape 40, mesh cloth 50, kraft paper 60, etc. Preferably, the mesh cloth 50 is a crack-resistant fiber mesh cloth 50, and the kraft paper 60 is a kraft paper 60 with good flexibility and high tensile strength, and the paper thickness is generally 0.2-0.3 mm.

[0032] Step S2: stick the elastic tape 40 on the corner surface of the second ceiling panel 20. To prevent the elastic tape 40 from falling off, drive self-tapping screws 30 into both sides of the elastic tape 40 to ensure that the elastic tape 40 is tightly fitted to the second ceiling panel 20.

[0033] Step S3: Attach the mesh cloth 50 to the outside of the elastic tape 40, with the mesh cloth 50 extending beyond the elastic tape 40. The specific implementation is as follows: apply glue evenly on the surface and surrounding areas of the elastic tape 40, and the glue coverage area is slightly larger than the size of the tape. Then, attach the mesh cloth 50 to the glue coverage area so that the edge of the mesh cloth 50 fits tightly with the second ceiling panel 20.

[0034] Step S4: attach the kraft paper 60 to the mesh cloth 50, and use a tool to compact the kraft paper 60 to remove bubbles and gaps. Preferably, glue is evenly applied on the surface of the mesh cloth 50, and the kraft paper 60 is attached to the outer layer of the mesh cloth 50 coated with glue, and a scraper or a roller is used to compact the kraft paper 60 to remove bubbles and gaps, and the edge of the mesh cloth 50 is exposed outside the kraft paper 60. Preferably, the glue is a high-strength construction glue compatible with gypsum board and kraft paper 60.

[0035] In an exemplary example, a method for constructing a ceiling corner anti-cracking structure further includes evenly applying a layer of glue on the surface and surroundings of the kraft paper 60, waiting for the glue to completely dry, the glue drying time is determined according to the properties of the glue, generally 24 hours, and then constructing an exterior layer 70, wherein the construction of the exterior layer 70 includes painting the wall paint. Preferably, the glue is an environmentally friendly glue to ensure that no harmful substances are released during the construction process and use.

[0036] The present invention provides a ceiling corner anti-cracking structure and a construction method thereof. The three-layer protection arrangement of elastic tape, mesh cloth and kraft paper at the corners and the arrangement of self-tapping screws to fix the elastic tape tightly to the surface of the ceiling board have a simple structure and are easy to construct. The high flexibility and tensile strength of the elastic tape, mesh cloth and kraft paper can effectively absorb and disperse the stress at the corners to reduce the risk of cracking. The elastic tape, mesh cloth and kraft paper are common materials with relatively low cost. At the same time, the ceiling corner anti-cracking structure provided by the present invention is suitable for various types of gypsum ceilings, is not limited by the shape and size of the ceiling, is easy to construct, has low construction cost, has a significant anti-cracking effect on the ceiling corners, can meet the quality requirements of modern fine decoration construction, and has broad application prospects.
