[0058] Embodiment 1:

[0059] See also Figure 1 and Figure 2The present embodiment provides an assembled corner ceiling assembly, which includes: an L-shaped corner plate 100 and a corner edging 200, the L-shaped corner plate 100 has a first connection portion 130 and a second connection portion 140, the first connection portion 130 and the second connection portion 140 form a certain angle, the first connection portion 130 is used to form a first joint 160, and the second connection portion 140 is used to form a second joint 170, the corner edging 200 is wrapped around the L-shaped corner plate 100, and one end of the corner edging 200 extends toward one side of the first connection portion 130 to at least wrap around the first joint 160, and the other end extends toward one side of the second connection portion 140 to at least wrap around the second joint 170.

[0060] In this embodiment, the assembled corner ceiling assembly can be installed at the corner of the ceiling. For example, an L-shaped corner plate 100 is used at the corner of the ceiling. The L-shaped corner plate 100 can be a prefabricated product, which avoids problems such as non-standard products and processing difficulties caused by on-site cutting or manual grinding.

[0061] For example, see Figure 1 The L-shaped corner plate 100 can form a stepped corner ceiling, which includes a first-level plane ceiling 600 and a second-level plane ceiling 700. A groove lamp 720 can be arranged between the first-level plane ceiling 600 and the second-level plane ceiling 700. The groove lamp 720 decorates the stepped corner ceiling by emitting light. The L-shaped corner plate 100 can be installed at the four corners of the first-level plane ceiling 600. The L-shaped corner plate 100 is used to form the second-level plane ceiling 700. For example, the L-shaped corner plate 100 and other top plane modules 710 are spliced ​​to form the second-level plane ceiling 700. The first-level plane ceiling 600 can be understood as the prior art, so the specific structure of the first-level plane ceiling 600 is not repeated.

[0062] Among them, see Figure 2The L-shaped corner plate 100 has a first connection portion 130 and a second connection portion 140. The first connection portion 130 and the second connection portion 140 form a certain angle. For example, the first connection portion 130 can be understood as an extension of the L-shaped corner plate 100 in the X-axis direction. The first connection portion 130 can be spliced ​​with other top plane modules 710 to form a first joint 160. The second connection portion 140 can be understood as an extension of the L-shaped corner plate 100 in the Y-axis direction. The second connection portion 140 can be spliced ​​with other top plane modules 710 to form a second joint 170. The first connection part 130 and the second connection part 140 can form an angle of 90°, that is, the L-shaped corner plate 100 is a right-angle corner plate, and the corner edging 200 is wrapped and arranged on the L-shaped corner plate 100. It can be understood that the corner edging 200 is wrapped and arranged on the edge of the L-shaped corner plate 100, wherein one end of the corner edging 200 is at least wrapped on the first seam 160 of the first connection part 130 to prevent the first seam 160 from cracking; at the same time, the other end of the corner edging 200 is at least wrapped on the second seam 170 of the second connection part 140 to prevent the second seam 170 from cracking.

[0063] Therefore, this embodiment uses an L-shaped corner plate 100 at the corner position of the ceiling, and the butt joint positions of the two ends of the L-shaped corner plate 100 are wrapped with a corner edging 200 to prevent cracking of the L-shaped corner plate 100 and other module panels, thereby enabling rapid assembly of the corner ceiling, convenient installation, and effectively reducing the difficulty of construction.

[0064] Specifically, see Figure 2 The corner edging 200 includes: an arc-shaped groove bottom 210, a first side panel 220 and a second side panel 230. The first side panel 220 is connected to the arc-shaped groove bottom 210, and the second side panel 230 is connected to the side of the arc-shaped groove bottom 210 away from the first side panel 220. The first side panel 220, the arc-shaped groove bottom 210 and the second side panel 230 are connected in sequence to form a groove structure 240 to wrap around the L-shaped corner panel 100.

[0065] In this embodiment, the first side panel 220 and the second side panel 230 form a groove structure 240, and the corner edging 200 can wrap the first seam 160 and the second seam 170 through the groove structure 240, which is equivalent to the first side panel 220 and the second side panel 230 being clamped at the seam position one above and one below to ensure the connection stability of the L-shaped corner panel 100 and avoid cracking of the first seam 160 and the second seam 170. At the same time, the arc-shaped groove bottom 210 can reflect the graceful shape of the arc and be beautifully decorated. For example, when assembling the corner edging 200 and the L-shaped corner panel 100, the L-shaped corner panel 100 can be inserted into the groove structure 240 of the corner edging 200, so that the first side panel 220 fits with the bottom of the L-shaped corner panel 100, and the second side panel 230 fits with the top of the L-shaped corner panel 100, and the first seam 160 and the second seam 170 of the L-shaped corner panel 100 are both embedded in the groove structure 240 to strengthen the connection strength between the L-shaped corner panel 100 and other top plane modules 710, and prevent the first seam 160 and the second seam 170 from cracking.

[0066] Specifically, see Figure 2 The depth of the first side plate 220 is greater than the depth of the second side plate 230 , and a plurality of nail holes 250 are provided on the first side plate 220 .

On the one hand, the depth of the first side panel 220 is greater than the depth of the second side panel 230, which can facilitate the identification of the first side panel 220 and allow the L-shaped corner panel 100 to be quickly inserted into the corner edging 200; on the other hand, when installing the screws, the screws pass from the first side panel 220 to the L-shaped corner panel 100, so that the corner edging 200 is fixed to the L-shaped corner panel 100, and the depth of the first side panel 220 is greater than the depth of the second side panel 230, which can prevent the screws from abutting against the second side panel 230, facilitate the installation of the screws, and improve the installation efficiency.

[0068] Specifically, see Figure 3 The first connection part 130 and the second connection part 140 both include staggered plates 150 , and the staggered plates 150 are used to form joints.

[0069] In this embodiment, the first connection part 130 forms a first joint 160 through the staggered plate 150 to further strengthen the connection at the position of the first joint 160 and prevent the first joint 160 from cracking, and the second connection part 140 forms a second joint 170 through the staggered plate 150 to further strengthen the connection at the position of the second joint 170 and prevent the second joint 170 from cracking. For example, the first connection part 130 can be spliced ​​with other top plane modules 710 through the staggered plate 150 to form the first joint 160, and the second connection part 140 can be spliced ​​with other top plane modules 710 through the staggered plate 150 to form the second joint 170, so as to further prevent the joints at both ends of the L-shaped corner plate 100 from cracking.
