[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] The utility model discloses a modular prefabricated light steel keel ceiling structure.

[0024] Reference Figures 1 to 4 A modular prefabricated light steel keel ceiling structure includes a prefabricated component 1 and a frame 2. The prefabricated component 1 is pre-installed on the ceiling, and can be pre-buried in the ceiling or connected to the ceiling by bolts or the like. A connecting rod 11 is fixedly connected to the bottom of the prefabricated component 1, and an adjusting sleeve 3 is rotatably connected to the frame 2. The adjusting sleeve 3 is provided with a threaded hole, and the threaded hole is threadedly connected to the connecting rod 11. A gypsum board 5 is connected to the bottom of the frame 2. Multiple connecting rods 11 and adjusting sleeves 3 can be provided on the gypsum boards 5 in the same row to improve the stability of the installation.

[0025] Before installation, the gypsum board 5 and the frame 2 are prefabricated and transported to the installation site, and the pre-installed part 1 is pre-installed on the ceiling, and then the adjusting sleeve 3 is rotated to make the threaded hole and the connecting rod 11 threadedly connected, so that the frame 2, the gypsum board 5 and the pre-installed part 1 are relatively fixed; the frame 2 and the gypsum board 5 are made by prefabrication, and the advanced equipment and precision instruments in the workshop can be used for production, which greatly improves the product quality and precision, and can also greatly reduce the time of on-site installation and improve the construction efficiency; in addition, the connection through the adjusting sleeve 3 is not only easy to disassemble, but also can adjust the height according to the needs, adapt to more occasions, and can be used to improve the neatness and beauty of the overall shape.

[0026] A locking nut 12 is threadedly connected to the connecting rod 11 , and the locking nut 12 abuts against the adjusting sleeve 3 to prevent the adjusting sleeve 3 from loosening.

[0027] The frame 2 includes a transverse keel 22 and a longitudinal keel 21 which are fixedly connected to each other. The transverse keel 22 is connected to the gypsum board 5, and the longitudinal keel 21 is arranged on the transverse keel 22. Each longitudinal keel 21 is fixedly connected to a plurality of transverse keels 22. A connecting plate 4 is arranged on the longitudinal keel 21. The connecting plate 4 covers the longitudinal keel 21 and is connected to the longitudinal keel 21 by bolts. A pressing plate 41 is integrally formed at the bottom of the connecting plate 4. The pressing plate 41 abuts against the top surface of the transverse keel 22. The end of the pressing plate 41 away from the connecting plate 4 is bent upward. When the connecting plate 4 is locked by bolts, the pressing plate 41 also applies pressure to the transverse keel 22, thereby improving the stability between the transverse keel 22 and the longitudinal keel 21.

[0028] A limiting rod 42 is welded on the connecting plate 4, and a limiting hole 31 is opened on the adjusting sleeve 3 for the limiting rod 42 to be inserted. The diameter of the limiting hole 31 is smaller than the threaded hole. The part of the limiting rod 42 located in the adjusting sleeve 3 is fixedly connected with an anti-slip block 43. The diameter of the anti-slip block 43 is larger than the diameter of the limiting hole 31, but not larger than the diameter of the threaded hole, thereby facilitating the adjustment sleeve 3 to rotate relative to the limiting rod 42, while reducing the possibility of separation of the adjustment sleeve 3 and the limiting rod 42.

[0029] A limiting ring 421 is fixedly connected to the limiting rod 42. The limiting ring 421 is located below the adjustment sleeve 3. The limiting ring 421 is convenient for limiting the adjustment sleeve 3 to prevent the adjustment sleeve 3 from falling excessively. An open gasket 422 is sleeved on the limiting rod 42. The open gasket 422 is located between the limiting ring 421 and the adjustment sleeve 3, and is provided in plurality. The open gasket 422 is made of plastic, such as PC, etc. The open gasket 422 can be sleeved on the limiting rod 42 from the side of the limiting rod 42. The number of the open gaskets 422 is set according to the height of the adjustment sleeve 3. The higher the height of the adjustment sleeve 3, the more the number of the open gaskets 422. After the adjustment sleeve 3 is tightened, the open gasket 422 is in a compressed state. On the one hand, it can support and prevent the adjustment sleeve 3 from loosening. On the other hand, it can reduce the shock of the limiting rod 42, and then reduce the shock of the frame 2 and the gypsum board 5.

[0030] The side edges of the bottom surface of the gypsum board 5 are chamfered to form a V-shaped groove 51 between adjacent gypsum boards 5 .

[0031] Working principle: The frame 2 and the gypsum board 5 are made in a prefabricated manner, and can be produced using advanced equipment and precision instruments in the workshop, which greatly improves product quality and precision, and can also greatly reduce the time of on-site installation and improve construction efficiency; in addition, the connection is made through the adjustment sleeve 3, which is not only convenient for disassembly, but also can adjust the height according to needs, adapt to more occasions, and can be used to improve the neatness and aesthetics of the overall shape. Through the setting of the limit ring 421, the open gasket 422 and the locking nut 12, the locking nut 12 is convenient for preventing the adjustment sleeve 3 from loosening, and the cooperation of the open gasket 422 and the limit ring 421 can, on the one hand, support and prevent the adjustment sleeve 3 from loosening, and on the other hand, it can also help the limit rod 42 to reduce shock.
