[0034] Specifically, the joints of the first gypsum board 1, the second gypsum board 2 and the third gypsum board 3 are filled with gypsum, and the inside or outside corners are pasted with inside or outside corner strips.

[0035] Through the above processing, the integrity and visual effect are improved.

[0036] Preferably, the first keel frame comprises:

[0037] A plurality of first keels 4 are connected at the top of the first gypsum board 1 or the second gypsum board 2 in a longitudinal direction, and each first keel 4 is arranged in a transverse direction, wherein one end of each first keel 4 on the first gypsum board 1 extends to the direction of the second gypsum board 2 and extends out of the first gypsum board 1 to form a first extension.

[0038] A first main keel 5 is arranged in a longitudinal direction and connected to the top of a plurality of first keels 4, and the first main keel 5 is connected to a roof panel through the first suspender 6.

[0039] Specifically, both the first gypsum board 1 and the second gypsum board 2 are connected to the corresponding first keel 4 by self-tapping screws.

[0040] Specifically, there are multiple first main keels 5, which are spaced apart along the length of the first keel 4.

[0041] By setting multiple first main keels 5, the overall integrity and stability of the first keel frame are improved.

[0042] Specifically, multiple first main keels 5 located at the same elevation are connected in series by connecting rods. The connecting rods are arranged horizontally, and each of the multiple first main keels 5 has a third connecting hole 12 for the connecting rod to pass through and connect.

[0043] By setting the connecting rod to connect multiple first main keels 5 at the same elevation, the stability of multiple first main keels 5 is ensured and shaking is avoided.

[0044] Preferably, there are at least two first hangers 6, and at least two first hangers 6 are spaced apart along the length of the first main keel 5.

[0045] By setting at least two of the first hanger rods 6, the connection stability of the first main keel 5 is improved.

The side of the second keel 7 opposite to the third gypsum board 3 is provided with a second locking groove for snapping into the corresponding first locking block 14.

[0054] By setting multiple first locking blocks 14 on both flanges of the second main keel 8, multiple first keels 4 and multiple second keels 7 can be selectively locked to any position on the corresponding flange of the second main keel 8 to meet design requirements, and avoid welding or drilling, making on-site assembly efficient and pollution-free.

[0055] Preferably, the bottom of the first main keel 5 is connected with a plurality of second locking blocks 11 at intervals along the length direction, and the second locking blocks 11 are adapted to the first locking slot.
