DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] An assembled ceiling structure includes a ceiling board 7, a butterfly-shaped connector 1, a ceiling edge trim 2, and a wall-ceiling overlapping part 3. One side of the butterfly-shaped connector 1 is fixedly connected to the ceiling board 7, and the other side of the butterfly-shaped connector 1 is inserted into another ceiling board 7. That is, adjacent ceiling boards 7 are connected by the butterfly-shaped connector 1. With the butterfly-shaped connector 1 having a fixed structure on one side and an inserted structure on the other side, it is convenient to fix the butterfly-shaped connector 1 to the ceiling board 7 on one side, which can prevent the butterfly-shaped connector 1 from falling off the ceiling board 7 during installation, improving the assembly efficiency between the ceiling boards. The ceiling edge trim 2 is installed on the edge ceiling board 7, and the edge ceiling board 7 is connected to the wall 4 through the wall-ceiling overlapping part 3. By overlapping the ceiling edge trim 2 and the wall-ceiling overlapping part 3, the connection between the edge ceiling board 7 and the wall-ceiling overlapping part 3 is achieved, greatly improving the assembly efficiency of the ceiling structure.

[0032] The ceiling edge trim 2 is provided with a overlapping part 2-3, and the wall-ceiling overlapping part 3 is provided with a ceiling overlapping part 3-1. The overlapping part 2-3 overlaps on the ceiling overlapping part 3-1. Through the setting of the overlapping part 2-3 and the ceiling overlapping part 3-1, it is convenient to assemble the ceiling edge trim 2 to the wall-ceiling overlapping part 3, improving the installation convenience of this installation structure. A ceiling limiting part 3-2 is provided on the ceiling overlapping part 3-1. By connecting the ceiling edge trim 2 and the wall-ceiling overlapping part 3 through the ceiling limiting part 3-2, the relative sliding of the ceiling edge trim 2 with respect to the wall-ceiling overlapping part 3 is prevented, thereby improving the installation stability of the ceiling board 7.

[0033] The ceiling edge trim 2 includes a ceiling connection part 2-2, a overlapping part 2-3, and a connection part 2-5. The ceiling connection part 2-2, the overlapping part 2-3, and the connection part 2-5 are connected to each other to form a hollow triangular structure. Among them, the ceiling connection part 2-2 is used to assemble the ceiling edge trim 2, and the overlapping part 2-3 is used to overlap the ceiling edge trim 2.

[0034] The overlapping part 2-3 is inclined, and overlapping steps 2-4 are arranged on the inclined surface of the overlapping part 2-3. The ceiling edge trim 2 is overlapped through the overlapping steps 2-4. Preferably, the inclined surface of the overlapping part is used to form an internal angle, which is convenient for hiding the ceiling edge trim 2.

[0035] The overlapping step 2-4 at least includes two overlapping steps 2-6. The ceiling edge trim 2 is assembled through different overlapping steps 2-6. Through the setting of multiple overlapping steps 2-6, the friction at the joint of the overlapping steps 2-6 and the ceiling step 3-5 is increased, thereby preventing the relative sliding of the wall-ceiling overlapping part 3 with respect to the ceiling edge trim 2 after assembly.

[0036] The ceiling connection part 2-2 is provided with a plug connector 2-7 for assembling the ceiling edge trim 2. A edge trim slot 2-11 is provided on the ceiling board 7, and the plug connector 2-7 is inserted into the edge trim slot 2-11, thereby facilitating the installation of the ceiling edge trim 2 on the ceiling board 7.

[0037] At the upper end of the ceiling connection part 2-2, there is a top cross bar 2-8. In this embodiment, the top cross bar 2-8 and the connection part 2-5 are on the same plane. At the lower end of the ceiling connection part 2-2, there is a bottom cross bar 2-9. In this embodiment, the bottom cross bar 2-9 is arranged in parallel with the top cross bar 2-8. The bottom cross bar 2-9 is connected to the overlapping step 2-4. The top cross bar 2-8 and the top cross bar 2-8 cooperate to provide a certain anti-torsion force to the ceiling edging member 2, improve the assembly strength between the ceiling edging member 2 and the ceiling board 7. The plug joint 2-7 is arranged between the top cross bar 2-8 and the bottom cross bar 2-9, which is convenient to ensure the connection strength between the ceiling edging member 2 and the ceiling board 7 through the top cross bar 2-8 and the bottom cross bar 2-9.

[0038] The thickness of the bottom cross bar 2-9 is less than that of the top cross bar 2-8, so that a limiting gap 8 is formed between the bottom cross bar 2-9 and the ceiling board 7. The ceiling limiting member 3-2 is connected to the limiting gap 8, so as to connect the ceiling edging member 2 and the wall-top overlapping member 3 through the ceiling limiting member 3-2, and prevent the ceiling edging member 2 from sliding relative to the wall-top overlapping member 3.

[0039] On the ceiling board 7, there are an upper-end groove 2-12 and a lower-end groove 2-13. The top cross bar 2-8 is inserted into the upper-end groove 2-12, and the bottom cross bar 2-9 is inserted into the lower-end groove 2-13. A limiting gap 8 is formed between the bottom cross bar 2-9 and the lower-end groove 2-13.

[0040] The ceiling limiting member 3-2 includes a connecting hook part 3-3 and an extending part 3-4. The connecting hook part 3-3 is connected to one side of the ceiling overlapping part 3-1 through the extending part 3-4. By inserting the connecting hook part 3-3 into the limiting gap 8, the ceiling edging member 2 is hooked, so as to fix the ceiling board 7 and the wall-top overlapping member 3 to each other. Preferably, the connecting hook part 3-3 is arranged perpendicular to the extending part 3-4, and the extending part 3-4 is arranged perpendicular to the ceiling overlapping part 3-1, which is convenient for the ceiling board 7 to be directly fixed above the connecting hook part 3-3 from top to bottom, and improves the assembly convenience.

[0041] The ceiling overlapping part 3-1 is inclined, that is, the ceiling overlapping part 3-1 can be an inclined slope. However, the inclined ceiling overlapping part 3-1 is likely to cause the ceiling board 7 to slide relative to the wall-top overlapping member 3. Therefore, in this embodiment, there is a ceiling step 3-5 in the ceiling overlapping part 3-1. The ceiling step 3-5 is used to overlap the ceiling board 7 to prevent the ceiling board 7 and the wall-top overlapping member 3 from sliding. At least two ceiling steps 3-5 are arranged in the ceiling overlapping part 3-1. Through the arrangement of multiple ceiling steps 3-5, the friction force at the joint of the overlapping step 2-6 and the ceiling step 3-5 is increased, so as to prevent the wall-top overlapping member 3 from sliding relative to the ceiling edging member 2 after assembly.

[0042] During the installation of the ceiling panel 7, the overlapping step 2-6 is overlapped on the ceiling step 3-5, so as to ensure that the ceiling edge trim 2 and the wall-top overlapping part 3 do not move relative to each other under the state of no external force, and ensure the overlapping stability of the ceiling edge trim 2 and the wall-top overlapping part 3.

[0043] A groove plate 3-7 is provided on the lower end surface of the wall-top overlapping part 3. The groove plates 3-7 are arranged on both side edges of the wall-top overlapping part 3. A wall panel slot 3-6 is formed between adjacent groove plates 3-7 for fixing the wall-top overlapping part 3 on the wall panel 4.

[0044] The main body of the wall-top overlapping part 3 is a hollow triangular structure, which reduces the mass of the wall-top overlapping part 3 and at the same time reduces the production cost of the wall-top overlapping part 3.

[0045] The wall panel 4 and the adjusting feet 5. The wall-top overlapping part 3 is assembled on the wall panel 4, the ceiling panel is overlapped on the wall-top overlapping part 3, and the adjusting feet 5 are arranged between the wall body 6 and the wall panel 4 to adjust the distance between the wall body and the wall panel 4, preventing gaps from being generated between the wall panel 4 and the wall body 6, so as to ensure the installation stability of the ceiling panel.

[0046] The butterfly-shaped connecting piece 1 includes a connecting plate 1-3 and a clamping part 1-1 and a plugging part 1-2 respectively connected to both sides of the connecting plate 1-3. The clamping part 1-1 is clamped inside one side of the ceiling panel, and the plugging part 1-2 is plugged inside another ceiling panel 7, so as to splice adjacent ceiling panels 7, and the adjacent ceiling panels 7 are separated by the connecting plate 1-3.

[0047] On both sides of the ceiling panel 7 assembled on the butterfly-shaped splicing structure, a clamping groove 1-8 and a plugging groove 1-9 are respectively provided. The clamping part 1-1 is assembled in the clamping groove 1-8, and the plugging part 1-2 is assembled in the plugging groove 1-9. In this embodiment, the clamping groove 1-8 is a dovetail groove, and the plugging groove 1-9 is a rectangular groove.

[0048] The clamping part 1-1 has a horizontally placed trapezoidal structure. The width of the clamping part 1-1 decreases from the end of the clamping part 1-1 to the connecting plate 1-3. The cross-sectional shape of the clamping part 1-1 is the same as the cross-sectional shape of the clamping groove 1-8, which is convenient for fixing the butterfly-shaped splicing structure on one side of the ceiling panel.

[0049] The plugging part 1-2 has a rectangular structure. The cross-sectional shape of the plugging part 1-2 is the same as the cross-sectional shape of the plugging groove 1-9, which is convenient for plugging the plugging part 1-2 into the plugging groove 1-9.

[0050] The installation steps of the butterfly-shaped splicing structure in this embodiment are as follows: (1) Insert the clamping part 1-1 into one side of the ceiling panel along the length direction of the clamping groove 1-8; (2) For the ceiling panel on the other side, along the width direction of the plugging groove 1-9, assemble the ceiling panel into the plugging part 1-2.

[0051] Both the clamping part 1-1 and the plugging part 1-2 are provided with empty slots 1-7, that is, the clamping part 1-1 and the plugging part 1-2 are hollow parts, which reduces the materials required for the production of this butterfly splicing structure and lowers the production cost.

[0052] In this embodiment, to ensure the strength of the ceiling board at the position where the clamping groove 1-8 is set, the connection width between the clamping part 1-1 and the connecting plate 1-3 is smaller than the connection width between the plugging part 1-2 and the connecting plate 1-3, so that the thickness of the ceiling board at the part where the clamping groove 1-8 is formed is larger, thereby ensuring the strength of the ceiling board.

[0053] The clamping part 1-1 and the plugging part 1-2 are fixedly connected to the lower end of the connecting plate 1-3, and a top limiting plate 1-4 is connected to the connecting plate 1-3. The connecting plate 1-3 is connected to the middle of the top limiting plate 1-4. Through the setting of the top limiting plate 1-4, it is convenient to further limit the ceiling board and provide a certain anti-torsion force for the ceiling board, thereby ensuring the assembly stability of the ceiling board and the butterfly splicing structure.

[0054] To prevent interference between the top limiting plate 1-4 and the ceiling board, a top slot 1-10 is provided at the top of the ceiling board, and the top limiting plate 1-4 is installed in the top slot 1-10.

[0055] To facilitate the storage of the butterfly splicing structure, the two side edges of the top limiting plate 1-4 are respectively located in the same vertical plane as the edges of the clamping part 1-1 and the plugging part 1-2.

[0056] A clamping slot 1-5 is formed between the top limiting plate 1-4 and the clamping part 1-1, and a slot 1-6 is formed between the top limiting plate 1-4 and the plugging part 1-2, which is convenient for the assembly of the ceiling board.

[0057] In this embodiment, the ceiling board 7 includes a ceiling board for assembling the ceiling edge trim 2 and a middle ceiling board for splicing. The side edge of the ceiling board for assembling the ceiling edge trim 2 is provided with an edge trimming slot 2-11, an upper end groove 2-12 and a lower end groove 2-13; the middle ceiling board for splicing is provided with a clamping groove 1-8 and a plugging groove 1-9, and both the edge trimming slot 2-11 and the clamping groove 1-8 are in the structure of a dovetail groove.

[0058] The installation method of the above-mentioned assembled ceiling structure includes the following steps.

[0059] S1. Determine the household size and prefabricate the butterfly connector 1, the ceiling edge trim 2, the wall-top lap joint 3, the ceiling board 7 and the wall panel 4.

[0060] S2. Assemble the wall-top lap joint 3 to the wall panel 4 on the bottom surface, seal the connection between the wall-top lap joint 3 and the wall panel 4 with glue, and reinforce the connection with screws for the second time.
