The support rod 1 is fixed to the top surface of the crossbeam 7. This facilitates the threaded connection between the screw hole on the top surface of the support rod and the bolt driven into the top surface of the wall, thereby fixing the position of the support rod 1 on the frame beam 21 and the crossbeam 7.

[0024] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom surface of the skeleton beam 21 is not closed, and the hanging plate 22 is provided in two sets. The hook 32 is shaped like a "√", and the distance between the two sets of hanging plates 22 is less than the distance between the protrusions on the top sidewalls of the two sets of hooks 32. The gypsum board 6 is fixed to the outer wall of the fixing frame 51 through the fixing groove 54, and the fixing frame 51 is slidably connected to the positioning plate 31 through the sliding groove 52. Thus, the gypsum board 6 is connected to the positioning plate 31 through the fixing frame 51. The decorative strip 4 slides inside the through groove 53, and the length of the fixing frame 51 is equal to the length of two decorative strips 4. The width of the through groove 53 is greater than the sum of the thicknesses of the two decorative strips 4, and the second spring 34 abuts against the top surface of the decorative strip 4; the positioning plate 31 is hung on the hanging plate 22 by the hook 32, and the first spring 33 is supported between the bottom surface of the skeleton beam 21 and the top surface of the positioning plate 31; so that the hook 32 can pass through the opening at the bottom end of the skeleton beam 21, so that the hook 32 can be hung on the hanging plate 22, and under the support of the first spring 33, the position of the positioning plate 31 is restricted, thereby connecting the positioning plate 31 with the skeleton beam 21.

[0026] The working principle of the fixing device for GRG gypsum board ceiling provided by this utility model is as follows:

[0027] In use, firstly, the top surface of the wall is measured and fixed points are marked. Then, bolts are driven into the marked points, and the support rod 1 is threadedly connected to the driven bolts, fixing the support rod 1 to the top surface of the wall to form a support point for the skeleton beam 21 and the crossbeam 7. Then, the plasterboard 6 is cut to the measured size, and its two sides are inserted into the fixing frame 51 through the fixing groove 54 for initial fixation. Then, two decorative strips are slid into one end of the through groove 53, so that the two decorative strips close the gap at the bottom end between the two sets of oppositely installed fixing frames 51. At the same time, the second spring 34 supports the top surface of the decorative strips to restrict the position of the decorative strips. Then, the plasterboard 6 is raised by the elevator, and the hook 32 fixed on the surface of the positioning plate 31 is aligned with the opening on the bottom surface of the skeleton beam 21. The hook 32 is squeezed into the interior of the skeleton beam 21 through its opening, and the first spring 33 abuts against the bottom surface of the skeleton beam 21. The spring 33 is compressed, and the hook 32 is hooked onto the hanging plate 22. Under the support of the first spring 33, the position of the positioning plate 31 is restricted, that is, the positioning plate 31 fixes the plasterboard 6 to the bottom surface of the fixed beam through the fixing frame 51. If the plasterboard 6 is damaged, the decorative strip is pushed upward, which compresses the second spring 34, and the decorative strip is pushed to slide, exposing the bottom end of the positioning plate 31. Then, the positioning plate 31 is pushed upward to make the positioning plate 31... By sliding along the groove 52 provided on the inner side wall of the fixing frame 51, the hook 32 can be disengaged from the hanging plate 22. Then, by inserting a tool from the bottom end of the positioning plate 31 and engaging the inner side of the clamping plate 35, the two hooks 32 are driven to move inward and pulled out, thus detaching the positioning plate 31 from the frame beam 21, and replacing the new gypsum board 6. This device has the advantage of facilitating the disassembly and replacement of the damaged gypsum board 6 when it is damaged by external force.

Firstly, the support rod 1 can be fixedly connected to the top surface of the wall, allowing the frame structure 2 and the crossbeam 7 to be fixed to the top surface of the wall via the support rod 1. The frame structure 2 and the crossbeam 7 then become the connection points for installing the gypsum board 6. Next, by inserting both sides of the gypsum board 6 into the fixing structure 5, the fixing structure 5 is secured to the edge of the gypsum board 6. Then, by sliding the decorative strip from the side of the fixing structure 5, the gap at the bottom end between the two fixing structures 5 is closed. Under the compression of the second spring 34, not only is the position of the decorative strip restricted, but it is also compressed so that its bottom surface is flush with the bottom surface of the fixing structure 5, facilitating the aesthetics of the connection node of the gypsum board 6. The plasterboard 6 is raised by a lift, aligning the hook 32 in the positioning structure 3 with the opening on the bottom surface of the frame structure 2. The hook 32 is then squeezed and deformed, locking into the interior of the frame structure 2 and securing the plasterboard 6. For replacement, the decorative strips are squeezed and slid together to expose the bottom surface of the positioning structure 3. The positioning structure 3 is then pushed upwards to detach from the frame structure 2. The hook 32 is then removed from the bottom of the frame structure 2 by using a tool to clamp and deform it inwards, allowing for the replacement of the new plasterboard 6. This device facilitates the disassembly and replacement of damaged plasterboard 6 when it is damaged by external force.
