[0021] In this embodiment, when the building undergoes expansion and contraction deformation due to factors such as temperature changes, the second threaded rod 3 and the third threaded rod 4 are brought closer to each other by rotating the adjuster 5, so as to facilitate the adjustment of the height of the T-shaped keel 6 and the metal sandwich color steel plate ceiling 12, ensuring that the metal sandwich color steel plate ceiling 12 can be flexibly adjusted to a suitable height according to the changes in the expansion joint, and can adapt to different expansion and contraction amounts, ensuring that the metal sandwich color steel plate ceiling 12 always remains flat to prevent deformation, thereby protecting the aesthetics, and the natural rubber 10 can effectively absorb and buffer the stress generated by the expansion and contraction deformation of the building, thereby ensuring the stability of the overall structure.

[0022] like Figure 1 As shown, a first slide groove 14 is provided on the square steel 8, a first threaded rod 2 passes through the first slide groove 14 and is fixed with a gasket 15 at one end, a nut 16 is threadedly connected to the first threaded rod 2, the floor 1 and the two first threaded rods 2 are connected by expansion wires 18, and the natural rubber 10 and the aluminum alloy strip 7 are connected by a first bolt 11.

[0023] After the first bolt 11 is replaced, it is rotated to move it downward until it enters the natural rubber 10 and limits it to prevent it from loosening.

[0024] like Figure 1 As shown, one end of the second threaded rod 3 and the third threaded rod 4 are fixedly installed with a stopper 17, the T-shaped keel 6 and the metal sandwich color steel plate ceiling 12 are connected by a second bolt 13, and a slider 19 is fixedly installed under the third threaded rod 4.
