[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0025] like Figure 1 As shown, a prefabricated frameless decorative ceiling includes a ceiling panel 1. The ceiling panel 1 is made of engineering plastic. Fixing seats 2 are distributed on the upper surface edge of the ceiling panel 1. The fixing seats 2 are screwed to the upper and lower adjustment components 3. The top of the upper and lower adjustment components 3 is provided with a connecting part 4. The connecting part 4 is fixedly connected to the ceiling slab 5. The upper and lower adjustment components 3 can adjust the vertical distance between the ceiling panel 1 and the ceiling slab 5.

[0026] The dimensions of the ceiling panel 1 can be accurately calculated in advance based on the area of ​​the house, eliminating the need for on-site cutting and processing of the ceiling panel 1.

[0027] like Figure 1-3 As shown, the fixing base 2 is in the shape of an inverted U. The fixing base 2 includes a base body 21 and connecting blocks 22 on both sides of the base body 21. The bottom of the connecting blocks 22 is fixedly connected to the upper surface of the ceiling panel 1.

[0028] The up-down adjustment assembly 3 includes an adjustment screw 31 and an adjustment nut 32. The base 21 is provided with a through hole 211 perpendicular to the ceiling panel 1. The base 21 is provided with a through groove 212 parallel to the ceiling panel 1. The through hole 211 communicates with the groove 212. The adjustment nut 32 is embedded in the groove 212. The adjustment screw 31 passes through the through hole 211 from top to bottom and is screwed to the adjustment nut 32.

[0029] To facilitate the rotation of the adjusting nut 32, the outer wall of the adjusting nut 32 is cylindrical, and anti-slip texture 322 is provided on the outer wall of the adjusting nut 32.

[0030] like Figure 6 As shown, in another embodiment, the top of the adjusting nut 32 is provided with a spherical crown 321, the screw hole of the adjusting nut 32 passes through the spherical crown 321, and the diameter of the through hole 211 is larger than the diameter of the screw hole of the adjusting nut 32.

[0031] By providing a spherical crown 321 at the top of the adjusting nut 32, the adjusting nut 32 can swing within a certain range along the central axis in the groove 212. This ensures that when the central axis of the adjusting screw 31 swings within a certain range, it can still be screwed into the corresponding adjusting nut 32, reducing the difficulty of installing the ceiling panel 1 and improving installation efficiency.

[0032] like Figure 3 As shown, in one embodiment, the connecting part 4 includes an expansion sleeve 41, a conical head 42, and a first locking nut 43. The conical head 42 is larger at the top and smaller at the bottom and is fixed to the top of the adjusting screw 31. The adjusting screw 31 passes through the expansion sleeve 41 and the conical head 42 is located on the outside of the top of the expansion sleeve 41. The first locking nut 43 is screwed to the adjusting screw 31 and is located at the bottom of the expansion sleeve 41.

[0033] like Figure 1-3 As shown, during installation, first, holes are drilled in the ceiling slab 5. The adjusting screw 31 is inserted into the expansion sleeve 41, and the expansion sleeve 41 and the conical head 42 are embedded in the holes. A spring and a washer can be fitted onto the adjusting screw 31 above the first locking nut 43. Rotating the first locking nut 43 causes the conical head 42 to expand the expansion sleeve 41 outward, and the expansion sleeve 41 is pressed and tightened against the hole wall in the ceiling slab 5. The first locking nut 43 is pressed against the bottom end of the expansion sleeve 41 by the spring and the washer, thus fixing the adjusting screw 31. Then, the lower end of the adjusting screw 31 is passed through the through hole 211 of the fixing seat 2 and screwed onto the adjusting nut 32. By rotating the adjusting nut 32, the vertical distance between the ceiling panel 1 and the ceiling slab 5 can be adjusted to ensure that each ceiling panel 1 is in the same plane and to ensure the overall flatness of the ceiling.

[0034] like Figure 5As shown, in another embodiment, the connecting part 4 includes an inner sleeve 44, a top plate 45, and a second locking nut 46. The top plate 45 is vertically fixed to the top of the inner sleeve 44. The inner cavity of the inner sleeve 44 is provided with an internal threaded hole. The upper part of the adjusting screw 31 is screwed to the inner sleeve 44. The adjusting screw 31 is screwed to the second locking nut 46. The top plate 45 has a plurality of mounting holes 451 evenly distributed along the circumference.

[0035] The top plate 45 can be fixed to the ceiling slab 5 by screws or expansion bolts passing through the mounting holes 451. After screwing the adjusting screw 31 into the appropriate position of the inner sleeve 44, rotate the second locking nut 46 to lock it against the bottom end of the inner sleeve 44, thus achieving the purpose of fastening the adjusting screw 31 to the inner sleeve 44. Pass the lower end of the adjusting screw 31 through the through hole 211 on the fixing seat 2 and screw it into the adjusting nut 32. By rotating the adjusting nut 32, the vertical distance between the ceiling panel 1 and the ceiling slab 5 can be adjusted to ensure that each ceiling panel 1 is in the same plane and to ensure the overall flatness of the ceiling.

[0036] When drilling and positioning holes in the ceiling slab 5, infrared projection positioning can be used to improve the accuracy of the screw connection between the adjusting screw 31 and the adjusting nut 32.

[0037] The ceiling panel 1 is rectangular, and the mounting brackets 2 are fixed at the four corners of the upper surface of the ceiling panel 1. Depending on the size and weight of the ceiling panel 1, 3-8 mounting brackets 2 can be distributed on the upper surface of the ceiling panel 1.

[0038] In another embodiment, the ceiling panel 1 is an irregularly shaped surface (such as plum blossom shape, peach shape, etc.), and multiple fixing seats 2 are provided and surround the edge of the irregularly shaped surface. The center of gravity of the polygon formed by the multiple fixing seats 2 coincides with the center of gravity of the ceiling panel 1 to ensure the balance of force on the ceiling panel 1.

[0039] When a user customizes an irregularly shaped ceiling panel 1, multiple fixing seats 2 are installed along the edge of the irregularly shaped ceiling panel 1. The center of gravity of the polygon formed by the multiple fixing seats 2 coincides with the center of gravity of the ceiling panel 1 to ensure the balanced force distribution on the ceiling panel 1. An upwardly extending side panel can be fixed to the edge of the irregularly shaped ceiling panel 1, and the irregularly shaped ceiling panel 1 can be fixed to the ceiling slab 5 via several connecting parts 4, without the need for a keel for installation.

[0040] In this embodiment, the fixing base 2 and the ceiling panel 1 are integrally formed and both are made of engineering plastic material to reduce production and installation costs.

[0041] like Figure 2 , 4As shown, the ceiling panel 1 has a rectangular cavity 12 with one end open. The edge of the rectangular cavity 12 has a slot 13 recessed into the ceiling panel 1. A ceiling insert 14 is inserted into the rectangular cavity 12. The edge of the ceiling insert 14 has a flange that matches the slot 13.

[0042] During installation, first pull the ceiling insert 14 out of the slot 13 of the rectangular cavity 12 to allow the construction workers to reach into the rectangular cavity 12 and rotate the adjusting nut 32 to adjust the height between the ceiling panel 1 and the ceiling slab 5. After installing one ceiling panel 1, insert the ceiling insert 14 back into the rectangular cavity 12.

[0043] like Figure 2 As shown, in one embodiment, hanging rings 15 are fixedly connected to the middle of the upper surface of the ceiling panel 1 and to the opposite sides of the rectangular cavity 12. When installing the ceiling panel 1, the ceiling insert 14 needs to be pulled out first, and the two ends of the hanging rope or suspension rod are connected to the corresponding hanging rings 15 respectively. The ceiling panel 1 can be easily moved by lifting the hanging rope or suspension rod with one hand, and the fixing seat 2 can be screwed to the corresponding adjusting screw 31 with the other hand. The height between the ceiling panel 1 and the ceiling slab 5 can be adjusted by rotating the adjusting nut 32.

[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
