Description

Technical Field

[0001] This application belongs to the field of building decoration and renovation, and in particular relates to a ceiling structure that prevents putty peeling and falling off. Background Technology

[0002] During the construction and decoration process, it is frequently observed that after the renovation is completed and the homeowner has moved in for a period of time, the plasterboard ceiling putty peels off or even falls off, requiring rework. After years of analysis and summarization, the main factors causing plasterboard ceiling putty peeling and falling off are as follows: 1. To reduce the fluidity of the plaster slurry, improve the moisture resistance of the plasterboard, increase surface smoothness, and improve its appearance, manufacturers add excessive amounts of water-based wax during the production process, reducing the adhesion of the plasterboard to the putty; 2. The putty manufacturer's technology is unstable, resulting in insufficient addition of adhesive powder to increase the adhesion of the putty powder or uneven mixing of the powder, leading to decreased putty adhesion; 3. The putty applied to the plasterboard ceiling is too thick, or dust adhering to the plasterboard surface was not cleaned before applying the putty. Utility Model Content

[0003] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this application is to provide a ceiling structure that prevents putty from peeling and falling off.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] A ceiling structure for preventing putty peeling and detachment includes: a wall, a ceiling surface, a ceiling base layer, gypsum board, and an adhesive layer. The ceiling base layer includes: a hanger, a main keel, and a secondary keel. The main keel is fixed to the ceiling surface by the hanger, the gypsum board is fixed to the secondary keel by fasteners, and the adhesive layer is attached to the surface of the gypsum board.

[0006] Furthermore, the spacing between adjacent suspension rods is set to be less than or equal to 80cm.

[0007] Furthermore, the spacing between adjacent main keels is set to be less than or equal to 80cm.

[0008] Furthermore, the spacing between adjacent secondary keels is set to be no more than 30cm.

[0009] Furthermore, the hanger is installed on the roof surface by screwing an expansion head into its upper end, and its lower end is inserted into the main keel.

[0010] Furthermore, the main keel is provided with fixing holes, and the lower end of the hanger rod is inserted into the fixing holes.

[0011] Furthermore, the secondary keel is engaged with the lower surface of the main keel 4.

[0012] Furthermore, the spacing of the peripheral fasteners of the gypsum board is 150mm, and the spacing of the central fasteners is less than or equal to 200mm.

[0013] Furthermore, a ceiling structure for preventing putty peeling and detachment also includes: a putty layer, which is attached to the surface of the adhesive layer.

[0014] Furthermore, a ceiling structure for preventing putty peeling and flaking also includes a decorative layer, which is applied or sprayed onto the surface of the putty layer.

[0015] Compared with the prior art, this application has the following technical effects:

[0016] (1) In this application, not only is the problem of the plasterboard ceiling putty peeling or even falling off from time to time, requiring rework and increasing maintenance costs, and the problem of the ceiling putty peeling and falling off reducing customer satisfaction and company reputation, but also the flatness of the ceiling is improved, thereby improving customer satisfaction and company reputation.

[0017] (2) In this application, lightweight plastering gypsum or finer plastering gypsum is applied to the surface of the gypsum board. The main component of both materials is calcium sulfate, which has a very strong adhesion to the gypsum board. Therefore, the adhesive layer will not peel or fall off when applied to the ceiling gypsum board surface. Furthermore, before construction, the gypsum board surface is thoroughly sprayed with a high-pressure water gun to remove any dust adsorbed on it. This further strengthens the adhesion between the adhesive layer and the gypsum board, preventing separation, peeling, or detachment. Moreover, because the adhesive layer can be applied thickly, even thicker than the putty layer, this technology also improves the smoothness of the putty layer, enhancing the overall construction quality of the ceiling.

[0018] (3) In this application, because the secondary keel is different from the wooden keel, it will not bend or deform due to changes in air humidity. Therefore, the ceiling base layer is not only very solid, but will also not arch or deform due to changes in air humidity. The structure is stable and reliable, which further reduces the risk of cracking, peeling and falling off of the adhesive layer and putty layer. Attached Figure Description

[0019] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0020] Figure 1 This is a schematic diagram of a ceiling structure designed to prevent putty peeling and detachment according to this utility model. Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1 As shown in this embodiment, a ceiling structure for preventing plaster peeling and detachment includes: a wall 1, a ceiling surface 2, a ceiling base layer, gypsum board 6, and an adhesive layer 7. The ceiling base layer includes: hangers 3, a main keel 4, and a secondary keel 5. The main keel 4 is fixed to the ceiling surface 2 via the hangers 3. The gypsum board 6 is fixed to the secondary keel 5 via fasteners. The adhesive layer 7 is attached to the surface of the gypsum board 6. This design not only solves the problem of occasional plasterboard ceiling plaster peeling and even detachment, requiring rework and increasing maintenance costs, but also addresses the issue of reduced customer satisfaction and company reputation due to plaster peeling and detachment. Furthermore, it improves the flatness of the ceiling, thereby enhancing customer satisfaction and company reputation.

[0023] Furthermore, in this embodiment, the spacing between adjacent suspension rods is set to be less than or equal to 80cm.

[0024] Furthermore, in this embodiment, the spacing between adjacent main keels is set to be less than or equal to 80cm.

[0025] Furthermore, in this embodiment, the spacing between adjacent secondary keels is set to be no greater than 30cm.

[0026] Preferably, in this embodiment, the suspension rod 3 is a threaded rod with a diameter of 8mm. It is installed on the roof surface 2 by screwing in the expansion head at its upper end, and the lower end is inserted into the fixing hole of the main keel and tightened with an adapter nut to suspend the main keel 4 below the roof surface.

[0027] Preferably, in this embodiment, the main keel 4 is made of a commonly used ceiling material in building decoration and is processed from high-quality steel strip. It is the main load-bearing component of the light steel keel ceiling, with high strength and light weight. The surface is galvanized for corrosion resistance. Unlike wooden keels, it will not bend or deform due to changes in air humidity. The secondary keel 5 transfers the load of the ladder to the roof surface 2.

[0028] Preferably, in this embodiment, the secondary keel 5 is made of a commonly used ceiling material in building decoration and renovation, processed from high-quality steel strips, which is high in strength, lightweight, and galvanized for corrosion resistance. It is tightly attached to the lower surface of the main keel 4 by snapping it in, transferring the load from the plaster 6, adhesive layer 7, putty layer 8, and decorative layer 9 to the main keel 4. Because the secondary keel 5 is different from the wooden keel, it will not bend or deform due to changes in air humidity. The ceiling base layer is not only very firm, but also will not arch or deform due to changes in air humidity, resulting in a stable and reliable structure. This further reduces the risk of cracking, peeling, and falling off of the adhesive layer 7 and putty layer 8.

[0029] Preferably, in this embodiment, the gypsum board 6 is a commonly used ceiling decoration material in building decoration, which is high in strength and lightweight. It is fixed to the base layer composed of the secondary keel 5 with wood screws. Along the secondary keel 5, the nail spacing around the perimeter of the gypsum board 6 is 150mm, and the nail spacing in the middle of the gypsum board 6 is 200mm. Furthermore, because the spacing between adjacent hangers is 80cm, which is much smaller than the national standard of 1.2 meters; the spacing between the main keels is 80cm, which is much smaller than the national standard of 1.1m; and the spacing between the secondary keels is 30cm, which is the minimum value of 30-40cm in the national standard, the gypsum board 6 is fixed to the flat ceiling base layer with wood screws, resulting in even stress distribution and preventing localized sagging and deformation. This reduces the risk of the putty layer 8 peeling or even falling off, requiring rework.

[0030] Preferably, in this embodiment, the adhesive layer 7 is formed by applying lightweight plaster gypsum to the surface of the gypsum board 6. The main component of this material is calcium sulfate, which has a very strong adhesion to the gypsum board 6, preventing peeling or detachment. Furthermore, before construction, the surface of the gypsum board 6 is thoroughly sprayed with a high-pressure water gun to remove any dust, further strengthening the adhesion between the adhesive layer 7 and the gypsum board 6, preventing separation, peeling, or detachment. Moreover, because the adhesive layer 7 can be applied thickly, even thicker than the putty layer, this technology also improves the smoothness of the putty layer 8, enhancing the overall construction quality of the ceiling.

[0031] Preferably, in this embodiment, the putty layer 8 is mainly composed of talc and calcium carbonate, and adheres to the surface of the adhesive layer 7. The putty has excellent adhesion to the plaster, so it will not separate from the adhesive layer 7. Because the putty layer 8 has high whiteness, fine texture, and is easy to sand, resulting in a high degree of smoothness after sanding, it can provide a high-quality base layer for the decorative layer 9.

[0032] Preferably, in this embodiment, the decorative layer 9 is made of latex paint, including a first coat of primer and two coats of topcoat applied by brushing or spraying onto the surface of the putty layer 8. It has high coverage, rich colors, and strong decorative properties.

[0033] Compared with the prior art, this application has the following technical effects:

[0034] This application not only solves the problem of plasterboard ceiling putty peeling or even falling off from time to time, requiring rework and increasing maintenance costs, but also solves the problem of reduced customer satisfaction and company reputation caused by ceiling putty peeling and falling off; it also improves the flatness of the ceiling, thereby improving customer satisfaction and company reputation.

[0035] In this application, lightweight plaster or finer gypsum plaster is applied to the surface of the gypsum board. The main component of both materials is calcium sulfate, which has a very strong adhesion to the gypsum board, preventing peeling or detachment. Furthermore, before construction, the gypsum board surface is thoroughly sprayed with a high-pressure water gun to remove any dust, further strengthening the adhesion between the adhesive layer and the gypsum board, preventing separation, peeling, or detachment. Because the adhesive layer can be applied thickly, even thicker than the putty layer, this technology also improves the smoothness of the putty layer, enhancing the overall quality of the ceiling construction.

[0036] In this application, because the secondary keel is different from the wooden keel, it will not bend or deform due to changes in air humidity. Therefore, the ceiling base layer is not only very solid, but also will not arch or deform due to changes in air humidity. The structure is stable and reliable, which further reduces the risk of cracking, peeling, and falling off of the adhesive layer and putty layer.
