[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention; See also Figures 1 to 7 The present invention provides an assembled curved GRG ceiling structure, comprising a roof 1, four sockets 2 being provided at the bottom of the roof 1, expansion bolts 3 being installed on the inner walls of the four sockets 2, screw rods 4 being fixedly connected to the bottom ends of the four expansion bolts 3, two locking rings 5 ​​being threadedly connected to the four screw rods 4, rotating sleeves 6 being rotatably connected to the four screw rods 4, cross bars 7 being fixedly connected to the four rotating sleeves 6, sliding sleeves 8 being slidably connected to the four cross bars 7, and support rods 9 being fixedly connected to the bottom ends of the four sliding sleeves 8. The bottom ends of the four support rods 9 are fixedly connected to the mounting plates 10, and the four mounting plates 10 are provided with mounting holes 11. Two GRG panels 12 are arranged under the roof 1. The tops of the two GRG panels 12 are pre-embedded with two embedded parts 13 fixedly connected to them. The sizes of the four embedded parts 13 are adapted to the mounting holes 11. The four embedded parts 13 are provided with annular concave holes 14, and the inner wall of the concave hole 14 is slidably connected to a locking rod 15. One end of the locking rod 15 is fixedly connected to a spring 16, and the other end of the locking rod 15 is provided with an inclined surface 17.

[0017] In the present invention, when installing the curved GRG ceiling structure, first place the GRG panel 12 to the position where it needs to be installed. At this time, it extends upward to the roof 1 according to the position of the embedded part 13 on the top of the GRG panel 12. This is the installation position of the expansion bolt 3. During the process, it is necessary to use professional positioning equipment to locate the position of the embedded part 13 and find the roughly corresponding area of ​​the embedded part 13. After the two expansion bolts 3 are installed, the fixation of the connecting parts is completed. Then, the GRG panel 12 is lifted again and the GRG panel 12 is moved to a position ten centimeters below the required installation position. At this time, the installer can change the height of the rotating sleeve 6 on the screw rod 4 by rotating the two locking rings 5, thereby changing the height of the mounting plate 10. Then, the height of the mounting plate 10 is adjusted to the required height for the installation of the embedded part 13 on the top of the GRG panel 12 by using a tape measure. Then, the rotating sleeve 6 can drive the cross bar 7 to rotate, thereby changing the position of the mounting plate 10. Then, the sliding sleeve 8 can be used to adjust the position of the mounting plate 10 again until the mounting holes 11 on the two mounting plates 10 are aligned with the GRG surface. After the two embedded parts 13 on the top of the plate 12 are aligned, the GRG panel 12 is pushed upward horizontally. The two embedded parts 13 on the GRG panel 12 will be inserted into the two mounting holes 11 respectively. During the process, the inclined surface 17 on the locking rod 15 will first contact the inner wall of the mounting hole 11. Then, as the embedded parts 13 rise, the locking rod 15 will retract into the inside of the mounting hole 11 until the locking rod 15 moves to the top of the mounting plate 10. At this time, the elastic force of the spring 16 will drive the locking rod 15 to pop out, and the locking rod 15 will be buckled on the top of the mounting plate 10. At this time, the installation The plate 10 can support the GRG panel 12 to complete the positioning of the GRG panel 12. Then the user rotates the locking ring 5 at the bottom, and the locking ring 5 will press the rotating sleeve 6 onto the locking ring 5 at the top, thereby locking the rotating sleeve 6. At this time, the rotating sleeve 6 cannot rotate, and the position of the cross bar 7 will be locked. Since the two expansion bolts 3 are installed randomly, there is a certain angle between the two cross bars 7, and the two sliding sleeves 8 cannot slide at the same time. The positions of the two sliding sleeves 8 will also be locked, thereby completing the installation and fixation of the GRG panel 12.

[0018] See also Figure 1 、 2 , 4, 5 and 6, wherein: an upper plate 18 is integrally formed on the top of the left GRG panel 12, a lower plate 19 is integrally formed on the top of the right GRG panel 12, cavities 20 arranged at equal distances are opened on the lower plate 19, the inner wall of the cavity 20 is slidably connected with a push plate 21, a spring 22 is fixedly connected between the top of the push plate 21 and the inner top wall of the cavity 20, the cavity 20 is filled with glue, grooves 23 arranged at equal distances are opened on the top of the lower plate 19, a rubber sheet 24 is fixedly connected to the inner wall of the groove 23, a conduit 25 is connected between the groove 23 and the cavity 20, and a puncture rod 26 arranged at equal distances is fixedly connected to the top of the upper plate 18.

[0019] In the present invention, after the two adjacent GRG panels 12 are installed, the upper plate 18 and the lower plate 19 on the two adjacent GRG panels 12 will fit together. First, it can play a positioning effect. Second, after the upper plate 18 and the lower plate 19 are fitted together, a position for an expansion joint will be reserved between the two adjacent GRG panels 12, which is beneficial for the installer to fill and level the gap between the two adjacent GRG panels 12. At the same time, after the installation of the left GRG panel 12 is completed, the right GRG panel 12 is moved up to allow the embedded part 13 to be inserted into the installation hole 11. During this process, the groove 23 on the lower plate 19 will be inserted into the piercing rod 26 at the bottom of the upper plate 18. Until the upper plate 18 and the lower plate 19 are fitted together, the piercing rod 26 will pierce the rubber sheet 24. At this time, the elastic force of the spring 22 will be released. 2 will drive the push plate 21 to descend, and the push plate 21 will squeeze out the glue in the cavity 20. The glue can be Dow Corning-995. The glue will enter the groove 23 from the conduit 25, and then the glue will penetrate into the gap between the upper plate 18 and the lower plate 19. When the glue solidifies, the upper plate 18 and the lower plate 19 can be connected, thereby realizing the connection and fixation between the two adjacent GRG panels 12, thereby improving the installation stability between the two adjacent GRG panels 12, and effectively reducing the occurrence of cracks between the two adjacent GRG panels 12. Compared with the traditional method of connecting the two adjacent GRG panels 12 with fasteners using tools, the installation difficulty is effectively reduced, and the GRG panel 12 will not be too large and cannot be reinforced after the installation is completed.

[0020] See also Figure 4 , wherein: the puncture rod 26 is provided with anti-slip plates 27 arranged at equal distances, and the anti-slip plates 27 are arranged in a circular shape.

[0021] In the present invention, the provision of the anti-slip plate 27 can increase the friction between the puncture rod 26 and the solidified glue, thereby improving the stability of the connection between the upper plate 18 and the lower plate 19.

[0022] See also Figure 4 , wherein: a filling hole 28 is opened on the upper plate 18, and a circular hole 29 corresponding to the filling hole 28 is opened on the inner wall of the groove 23.

[0023] In the present invention, after the glue is squeezed out, the glue is not only located in the gap between the upper plate 18 and the lower plate 19, but the glue also flows from the circular hole 29 into the filling hole 28. After the glue solidifies, it will be in the shape of a rod, thereby improving the stability of the connection between the upper plate 18 and the lower plate 19, and further improving the stability of the connection between the two adjacent GRG panels 12.

[0024] See also Figure 2, wherein: the top of the cross bar 7 is fixedly connected with a reinforcement plate 30 , and one side of the reinforcement plate 30 is fixedly connected to the rotating sleeve 6 .

[0025] In the present invention, the provision of the reinforcement plate 30 can improve the stability of the support of the crossbar 7, thereby improving the stability of the installation of the GRG panel 12.

[0026] See also Figure 3 , wherein: the top of the mounting plate 10 is fixedly connected with a reinforcement member 31 , and the top of the reinforcement member 31 is fixedly connected to the support rod 9 .

[0027] In the present invention, the provision of the reinforcement member 31 can enhance the strength of the support for the mounting plate 10 and further enhance the stability of the installation of the GRG panel 12 .

[0028] See also Figure 2 and 5 , wherein: a locking button 1 32 threadedly connected to the outer side of the rotating sleeve 6 is inserted, and a locking button 2 33 threadedly connected to the top of the sliding sleeve 8 is inserted.

[0029] In the present invention, after completing the installation of the GRG panel 12, the positions of the rotating sleeve 6 and the sliding sleeve 8 can be locked respectively by rotating the locking button 1 32 and the locking button 2 33, thereby further improving the locking stability of the mounting plate 10 and thereby improving the installation stability of the GRG panel 12.

[0030] See also Figure 3 , wherein: the embedded part 13 is sleeved with a limiting plate 34 fixedly connected thereto, and the limiting plate 34 is located below the locking rod 15.

[0031] In the present invention, the setting of the limiting plate 34 can limit the height of the embedded part 13, thereby preventing the GRG panel 12 from moving upward, thereby improving the practicality of the device.
