However, there are still problems that the gap between adjacent two modules is not easy to control and the aesthetic feeling is insufficient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an assembled ceiling flush joint structure to control the size of the gap between adjacent two ceiling substrates and improve the aesthetic feeling.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] An assembled ceiling flush joint structure includes a wall panel, a ceiling board, a keel, and a flush joint member.

[0006] The ceiling board includes multiple ceiling substrates. The number of keels is the same as the number of ceiling substrates. The keels are fixed on the top of the ceiling substrates, and the ceiling substrates are carried on the wall panel by the keels.

[0007] A flush joint member is provided between adjacent ceiling substrates. The flush joint member includes a flush joint female member and a flush joint plug-in member. A V-shaped groove is provided at the edge of the ceiling substrate. The edge of the ceiling substrate can be folded along the V-shaped groove to form a flanging. The flush joint female member and the flush joint plug-in member are respectively connected to the flangings of adjacent two ceiling substrates, and the flush joint plug-in member is inserted into the flush joint female member.

[0008] Further, the flush joint female member includes a first connecting portion extending along the vertical direction. A second connecting portion extending vertically outward is provided at the top of the first connecting portion. A ninety-degree right-angle groove is formed between the first connecting portion and the second connecting portion. The right-angle groove is arranged in cooperation with the flanging, so that the flush joint female member can be attached to a corner of the flanging.

[0009] Further, a serrated glue groove is provided inside the right-angle groove.

[0010] Further, a third connecting portion extending vertically upward is provided at the top of the first connecting portion. A fourth connecting portion extending vertically outward is provided at the top of the third connecting portion. The extending direction of the fourth connecting portion is the same as that of the second connecting portion. A slot for inserting the flush joint plug-in member is formed between the second connecting portion, the third connecting portion, and the fourth connecting portion.

[0011] Further, the flush connector includes a fifth connecting portion and a sixth connecting portion which are arranged in parallel with each other. A seventh connecting portion is provided between the tops of the fifth connecting portion and the sixth connecting portion. A rectangular groove is formed among the fifth connecting portion, the sixth connecting portion and the seventh connecting portion. The rectangular groove is arranged in cooperation with the flanging, so that the flush connector can be inserted on the flanging.

[0037] The flat joint structure of the present invention includes a wall panel 1, a keel 3, a ceiling board 2, and a flat joint 4

[0038] The ceiling board 2 includes multiple ceiling base boards 21. The wall board 1 is fixed on the wall surface. The number of keels 3 corresponds to that of the ceiling base boards 21. The ceiling bases are carried on the wall board 1 one by one through the keels 3. A flat joint 4 is provided between adjacent ceiling base boards 21 to form a whole for the entire ceiling board 2, thereby increasing the structural stability, avoiding loosening in the later stage, and controlling the gaps between the ceiling bases to make the whole more beautiful. A top module 6 is provided between the side of the ceiling board 2 and the wall board 1. A sliding edge trimmer 7 is provided in the top module 6. The keel 3 is indirectly placed on the top of the wall board 1 through the top module 6. Before the keel 3 is placed on the top of the wall board 1, the sliding edge trimmer 7 is retracted into the top module 6. After the keel 3 is placed on the top module 6, the sliding edge trimmer 7 slides outwards to cover the gap between the ceiling board 2 and the top module 6 to achieve edge trimming.

[0039] Specifically, the installation steps of the assembled kitchen and bathroom ceiling system are as follows:

[0040] After the top modules 6 and the sliding edge trimmers 7 on all four sides are installed, lift the assembled ceiling base board 21 to a position higher than the wall board 1, and gently place down the ceiling base board 21 so that the keel 3 longer than the ceiling base board 21 can be lapped on the top module 6;

[0041] Fold the edge of the ceiling base board 21 to form a flanging 22;

[0042] Install another ceiling base board 21 on the top module 6 and also fold it to form a flanging 22;

[0043] Connect adjacent two ceiling base boards 21 with the flat joint 4, and then install other ceiling base boards 21 in sequence to complete the flat joint.

[0044] The flat joint 4 is composed of a flat joint female part 41 and a flat joint male part 42. The flat joint female part 41 and the flat joint male part 42 are respectively connected to the flangings 22 of two adjacent ceiling base boards 21, and the flat joint male part 42 is inserted into the flat joint female part 41. After the flat joint male part 42 and the flat joint female part 41 are inserted, the process gap between the two ceiling base boards 21 can be controlled within 2.5 mm.

[0045] Among them, the flush joint female part 41 includes a first connecting part 411 extending along the vertical direction. At the top of the first connecting part 411, a second connecting part 412 extending vertically outward is provided. A right-angle groove 413 of ninety degrees is formed between the first connecting part 411 and the second connecting part 412. Inside the right-angle groove 413, a serrated glue groove 5 is provided. At the top of the first connecting part 411, a third connecting part 414 extending vertically upward is provided. At the top of the third connecting part 414, a fourth connecting part 415 extending vertically outward is provided. The extending direction of the fourth connecting part 415 is the same as that of the second connecting part 412. A slot 416 for inserting the flush joint plug-in 42 is formed among the second connecting part 412, the third connecting part 414, and the fourth connecting part 415.

[0046] The flush joint plug-in 42 includes a fifth connecting part 421 and a sixth connecting part 422 arranged in parallel with each other. Between the tops of the fifth connecting part 421 and the sixth connecting part 422, a seventh connecting part 423 is provided. A rectangular groove 424 is formed among the fifth connecting part 421, the sixth connecting part 422, and the seventh connecting part 423. Inside the rectangular groove 424, a serrated glue groove 5 is provided. At the top of the fifth connecting part 421, an eighth connecting part 425 extending vertically outward is further provided. The eighth connecting part 425 is in interference fit with the slot 416 and can be tightly inserted into the slot 416.

[0047] The more detailed installation method of the flush joint 4 is as follows: Structural glue is applied to the glue grooves 5 of the flush joint female part 41 and the flush joint plug-in 42. The serrated design of the glue grooves 5 enables the flush joint female part 41 and the flush joint plug-in 42 to be tightly connected to their respective flanges 22; the ceiling substrate 21 and the flush joint female part 41 spliced on the ground are lifted to the top of the wall panel 1. Then, after another ceiling substrate 21 and the flush joint plug-in 42 are installed well on the ground and lifted to the top of the wall panel 1, the ceiling substrate 21 is then horizontally moved to insert the flush joint plug-in 42 into the flush joint female part 41.

[0048] Among them, the fifth connecting part 421 of the flush joint plug-in 42 is clamped between two ceiling substrates 21. The thickness of the fifth connecting part 421 is 2.5 mm, so that all the process seams between the ceiling substrates 21 can be controlled within 2.5 mm.

[0049] As an alternative embodiment, the card slot 61 at the bottom of the top module 6 has two outer edges 62 of one long and one short. The purpose is to distinguish the installation direction of the top module 6, and another purpose is to facilitate clamping at the bottom of the wall panel 1.

[0050] The top module 6 is overall in a long strip shape. Its upper part is composed of a bottom edge, a rear side edge, a top edge, and a front side edge. The bottom edge, the rear side edge, the top edge, and the front side edge form a rectangular structure, and a cavity 63 is formed in the middle. The bottom edge is parallel to the top edge. Among them, the bottom edge is carried on the top of the wall panel 1, and the top edge is used for the keel 3 to be carried.

[0051] A through slot 64 is provided on the front side edge. The sliding edge closing member 7 includes a sliding portion 71. The top and bottom of the sliding portion 71 are respectively attached to the top edge and the bottom edge. A sealing edge portion 72 extending horizontally towards the through slot 64 is provided on the sliding portion 71. Openings are provided at both upper ends of the upper part of the strip-shaped top module 6. The sliding edge closing member 7 can be inserted into the top module 6 from the opening at any one end of the top module 6, and the sliding edge closing member 7 can slide along the bottom plate in the cavity 63 of the top module 6.

[0052] After the ceiling board 2 is installed, the sliding edge closing member 7 is slid inside the top module 6, the sealing edge portion 72 slides out from the through slot 64 and then is pulled outwards. Limit slots 73 are provided at both the upper and lower ends of the sliding portion 71, and cooperating limit protrusions 65 are provided on the bottom edge and the top edge of the top module 6. When pulled to the bottom, the limit protrusions 65 are stuck in the limit slots 73 to position the sliding edge closing member 7 and complete the edge closing. This is used to prevent the sliding edge closing member 7 from loosening.

[0053] Wherein, the top and bottom of the sliding portion 71 are respectively attached to the top edge and the bottom edge. Besides being used to limit its sliding, the sliding portion 71 itself is also used to support the top edge and prevent the rectangular structure formed by the bottom edge, the rear side edge, the top edge and the front side edge from deforming.

[0054] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
