The shell 1 is an aluminum plate wrapped around the outer surface of the PVC foam board 2 to provide additional protection and decoration. The PVC foam board 2 is made of polyvinyl chloride and contains a foaming agent and a flame retardant.

[0029] Reference Figure 3-4 , the two sides of the shell 1 are respectively designed with a side groove 7 and a semicircular groove 9, and one side of the shell 1 is also provided with a semi-arc groove 8 connected to the semicircular groove 9. A No. 1 connecting piece 4 is fixedly installed in the side groove 7. The connecting piece consists of a cylinder 11 and an inner semi-arc cylinder 12. The cylinder 11 is firmly embedded in the side groove 7.

[0030] Correspondingly, the semicircular groove 9 and the semi-arc groove 8 on the other side of the housing 1 correspond to the side groove 7 in relative position, and are used to cooperate with the connecting assembly to realize the splicing of the two boards.

[0031] Reference Figure 5 The connecting assembly also includes a second connecting member 5, which is composed of a rotating cylinder 14 and an outer semi-arc cylinder 13.

[0035] Specifically, two PVC foam boards 2 with shells 1 on their surfaces are fitted together, and the rotating cylinder 14 is embedded in the corresponding semicircular groove 9. Then, the slide plate 6 is moved so that the slide plate 6 drives the outer semi-arc cylinder 13 and the rotating cylinder 14 to move through the connecting plate 16, so that one section of the outer semi-arc cylinder 13 is rotated ninety degrees along the center point of the rotating cylinder 14 to the inside of the semi-arc groove 8, so that the two are buckled with each other to achieve the effect of connection, and the buckle 15 located on the side of the outer semi-arc cylinder 13 will cooperate with the card groove inside the semi-arc groove 8 to fix the outer semi-arc cylinder 13, thereby achieving the effect of fixed connection, and by using bolts to make them pass through the through hole 3, the cylinder 11 and the inside of the inner semi-arc cylinder 12 and finally connected and installed on the top keel frame of the ceiling, the installation of the foam board and the connection between the two adjacent foam boards are finally realized, thereby obtaining a better connection effect and avoiding the generation of formaldehyde here.
