[0025] The deformation and cracking of gypsum board ceilings have become a common quality problem. The tensile strength and breaking load of the gypsum board itself are reasons that cannot be ignored. The ceiling includes a skeleton structure and gypsum board. The ceiling is used to beautify the interior space, but it is prone to deformation and even cracking during its use. Therefore, it is necessary to increase the screw spacing to improve the gypsum board's ability to resist deformation. However, increasing the screw spacing will cause stress concentration, and a large stress difference will occur between the screw fixing point and the surrounding gypsum board.

[0026] In order to solve the technical problem, the utility model provides a suspended ceiling, aiming to provide a suspended ceiling with high strength and light weight.

[0027] See also Figure 1 The suspended ceiling provided by the utility model is used to be installed on the top of the indoor space of the building. The suspended ceiling includes: a skeleton structure 10, a gypsum board 20, a reinforcing net 40 and a connecting piece 30. The skeleton structure 10 is extended on the surface of the building structure, and one side of the skeleton structure 10 is used to be installed on the building structure at the top of the indoor space of the building;

[0028] The gypsum board 20 is installed on the other side of the frame structure 10, and the gypsum board 20 is provided with a mounting hole; the reinforcing mesh 40 is provided on the side of the gypsum board 20 away from the frame structure 10

[0029] The connecting member 30 passes through the reinforcing mesh 40 and the mounting hole in sequence and is connected to the frame structure 10 , so as to connect the reinforcing mesh 40 and the gypsum board 20 to the frame structure 10 .

[0030] The skeleton structure 10 is a lightweight and high-strength material, installed on the top of the building, and provides a stress point for the entire ceiling. The gypsum board 20 covers the other side of the skeleton structure 10, and the reinforcing mesh 40 is located on the side of the gypsum board away from the top of the building, which enhances the overall bending and crack resistance. At the same time, the weight of the entire ceiling system is relatively small. The connector 30 passes through the mounting holes of the reinforcing mesh and the gypsum board, and is connected to the skeleton structure by anchoring or bonding, thereby achieving a firm connection between the gypsum board and the skeleton structure.

[0031] Combination Figure 1 As shown, in the embodiment of the present invention, the reinforcing mesh 40 is made of one of steel, glass fiber cloth or carbon fiber cloth.

[0032] In this embodiment, the reinforcing net 40 is made of one of steel, glass fiber cloth or carbon fiber cloth, wherein the steel can be galvanized steel or stainless steel, preferably stainless steel. The high strength and durability of stainless steel ensure the service life of the ceiling, and the length of the reinforcing net can be equal to the length of the skeleton structure.

[0033] Combination Figure 1 As shown, in the embodiment of the present utility model, a plurality of connecting members 30 are provided, and the plurality of connecting members 30 are spaced apart in the extension direction of the skeleton structure, and the distance between two adjacent connecting members 30 in the extension direction of the skeleton structure is 30 mm-100 mm.

[0034] In this embodiment, the connecting piece 30 of the suspended ceiling is specifically configured as a self-tapping screw, which is arranged at intervals and evenly arranged along the extension direction of the gypsum board 20 to enhance the stability and bearing capacity of the overall structure. The spacing between two adjacent connecting pieces 30 in the extension direction of the gypsum board 20 is set to 30mm to 100mm, preferably 70mm. In the traditional construction process of suspended ceiling gypsum board, the screw spacing is generally 150mm-170mm. Although the construction is convenient, such a spacing is too large. For large suspended ceiling spaces with large spans, deformation or even cracking is likely to occur during use. In practical applications, double-layer gypsum boards have to be used for reinforcement. This setting not only ensures the uniform distribution of the load, but also improves the overall rigidity and crack resistance of the suspended ceiling, reduces the use of materials, and does not affect the structural performance.

[0035] Through the above arrangement, the connector 30 limits the displacement of the gypsum board 20, effectively preventing the expansion of cracks caused by temperature and humidity changes. In addition, the construction personnel can flexibly adjust the spacing of the connector 30 according to specific construction requirements and site conditions to adapt to different installation requirements.

[0036] Combination Figure 1 As shown, in the embodiment of the present invention, a plurality of reinforcing nets 40 are provided, and the plurality of reinforcing nets 40 are arranged at intervals in the extension direction of the skeleton structure, and each connecting member 30 abuts a reinforcing net 40 against the gypsum board 20 .

[0037] In this embodiment, the reinforcement mesh 40 of the suspended ceiling is configured as a plurality of independent meshes, which are spaced apart along the extension direction of the gypsum board 20 to provide more uniform and enhanced support. It is found in practice that the deformation of the gypsum board is closely related to the screws. The smaller the spacing between the screws fixing the gypsum board and the denser the screws, the greater the restraint force of the keel on the gypsum board, the greater the tensile strength and breaking load of the gypsum board, and the higher the ability of the gypsum board to resist deformation; but at the same time, the screws will produce stress concentration, and the screws fixed around the gypsum board will produce a large stress difference. In order to ensure that the screws can fully play their role, the concentrated stress needs to be dispersed.

[0038] Therefore, the reinforcing meshes 40 arranged at intervals can more effectively disperse and bear the stress acting on the gypsum board 20, reducing deformation or cracking caused by local overload. Each connector 30 abuts a reinforcing mesh 40 against the gypsum board 20, ensuring that the reinforcing mesh and the gypsum board are tightly matched to form a whole body that bears the load together.

[0039] Combination Figure 1 As shown, in the embodiment of the present invention, the thickness of the reinforcing mesh 40 is in the range of 0.01 mm to 0.2 mm.

[0040] In this embodiment, the thickness of the reinforcing mesh 40 ranges from 0.01mm to 0.2mm, and the length and width ranges from 10mm to 40mm, preferably a 30mm square, which provides reinforcement for the gypsum board 20. This size setting ensures that the reinforcing mesh 40 can effectively improve the bending strength and overall stability of the gypsum board without excessively increasing the deadweight of the ceiling. By arranging multiple reinforcing meshes 40 at intervals in the extension direction of the gypsum board 20, each connector 30 precisely abuts the reinforcing mesh 40 against the gypsum board to form a uniformly distributed support structure. The load transfer path is optimized, the risk of cracking of the gypsum board due to uneven force is reduced, and the adaptability of the ceiling to temperature changes and humidity fluctuations is enhanced, thereby improving the durability of the ceiling.

[0041] Combination Figure 1As shown, in an embodiment of the present utility model, the skeleton structure 10 is a covering keel, and a plurality of skeleton structures 10 are provided. The plurality of skeleton structures 10 are arranged at intervals in a direction perpendicular to the extension direction of the skeleton structure 10, and the spacing between two adjacent skeleton structures 10 is 400mm-1000mm.

[0042] In this embodiment, the frame structure 10 adopts the arrangement of the covering keel, which allows multiple frame structures 10 to be arranged at intervals perpendicular to the extension direction thereof to form the main load-bearing frame of the ceiling. The spacing between two adjacent frame structures 10 is set in the range of 400mm to 1000mm, preferably 800mm, which ensures sufficient structural strength and meets the economic and construction convenience.

[0043] The provision of the covering keels enables the skeleton structure 10 to provide a larger surface area to support the gypsum board 20, while enhancing the stability and load-bearing capacity of the overall structure. By arranging them at intervals in the vertical direction, the skeleton structure 10 provides uniform support points for the gypsum board 20, effectively dispersing the load acting on the gypsum board and reducing the risk of deformation or cracking caused by local overload.

[0044] Furthermore, the staggered arrangement of the skeleton structure 10 forms an air layer inside the suspended ceiling, which not only helps to improve the sound insulation effect of the suspended ceiling, but also helps to improve the thermal insulation performance. The connector 30 firmly connects the gypsum board 20 to the covering keel through the reinforcing net 40, ensuring the durability of the overall structure.

[0045] Combination Figure 1 As shown, in the embodiment of the present utility model, the material of the skeleton structure 10 is galvanized steel or stainless steel, and the thickness of the skeleton structure ranges from 0.5 mm to 0.6 mm.

[0046] In the embodiment of the utility model, the skeleton structure 10 is made of galvanized steel or stainless steel, preferably stainless steel, which ensures the corrosion resistance and durability of the skeleton structure and provides the necessary strength to support the entire ceiling system. Stainless steel has excellent weather resistance and corrosion resistance, is suitable for various environmental conditions, prolongs the service life of the ceiling and reduces maintenance costs.

[0047] Furthermore, the thickness of the stainless steel ranges from 0.5mm to 0.6mm, providing sufficient rigidity for the skeleton structure while maintaining the lightness of the overall ceiling system. This not only meets the structural load-bearing requirements, but also avoids excessive increase in material costs, thus achieving the economy of the ceiling.

[0048] Combination Figure 1As shown, in an embodiment of the utility model, a plurality of gypsum boards 20 are provided, and a plurality of connectors 30 are provided on each gypsum board 20. The plurality of connectors 30 connect each gypsum board 20 to a skeleton structure 10, and the plurality of gypsum boards 20 are connected to the building structure that is spread all over the top of the interior space of the building.

[0049] In this embodiment, the gypsum board 20 is modularly arranged, and each gypsum board 20 is equipped with a plurality of connectors 30. Each gypsum board 20 is connected to the skeleton structure 10 at multiple points through the plurality of connectors 30 thereon. Each connector 30 is evenly distributed at a specific position of the gypsum board 20, ensuring the uniformity and stability of the connection, so that each gypsum board 20 is firmly fixed to the corresponding skeleton structure 10.

[0050] Combination Figure 1 As shown, in an embodiment of the present utility model, the suspended ceiling further includes a leveling layer 50 , which is disposed on a side of the reinforcing mesh 40 away from the gypsum board 20 and covers the reinforcing mesh 40 .

[0051] In this embodiment, the leveling layer 50 is arranged on the side of the reinforcing mesh 40 away from the gypsum board 20, covering each reinforcing mesh 40, and the thickness of the leveling layer 50 ranges from 0.2 mm to 2 mm, preferably 1 mm, ensuring the improvement of the flatness and integrity of the ceiling surface. The leveling layer not only provides a uniform base for the reinforcing mesh 40, but also helps to eliminate the influence caused by the small gap or unevenness that may exist between the gypsum board 20 and the reinforcing mesh 40. The flat coverage of the leveling layer 50 ensures the aesthetics and decorative effect of the ceiling.

[0052] Combination Figure 1 As shown, in an embodiment of the present invention, the suspended ceiling further comprises a protective layer 60, which is arranged on a side of the leveling layer 50 away from the reinforcing mesh 40 and covers the leveling layer 50, and the thickness of the protective layer 60 ranges from 0.1 mm to 0.3 mm.

[0053] In this embodiment, the protective layer 60 is arranged on the side of the leveling layer 50 away from the reinforcing mesh 40, and fully covers the leveling layer 50, forming an additional protection for the ceiling system. The protective layer 60 is specifically set to be a material such as latex paint, inorganic paint, etc. with a thickness range of 0.1mm to 0.3mm, which ensures sufficient protection ability and avoids excessively increasing the weight of the ceiling.

[0054] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
