Detailed Embodiment

[0018] The following will introduce the present utility model in detail with reference to the drawings:

[0019] Embodiment: As shown in the Figures 1 to 3 drawings, this spliced noise reduction, sound absorption, and fireproof rock wool board includes a main body frame 1, a fitting groove 1-1, a buffer layer 2, a sound absorption and noise reduction layer 3, a cavity 3-1, a waterproof layer 4, a reinforcing fireproof layer 5, an upper layer 5-1, a lower layer 5-2, a longitudinal reinforcing rib 5-3, a transverse reinforcing rib 5-4, a T-shaped block 6, and a T-shaped slot 7.

[0020] Refer to the Figure 1 drawings 2, a fitting groove 1-1 is formed on the upper surface of the main body plate frame 1. A buffer layer 2, a sound absorption and noise reduction layer 3, and a waterproof layer 4 are sequentially placed layer by layer from bottom to top in the fitting groove 1-1, and the buffer layer 2, the sound absorption and noise reduction layer 3, and the waterproof layer 4 are adhesively connected in sequence. The enhanced fireproof layer 5 includes an upper layer 5-1 and a lower layer 5-2. Among them, the lower layer 5-2 is placed in the fitting groove 1-1 and pressed on the waterproof layer 4, so that the upper layer 5-1 is exposed from the fitting groove 1-1. Preferably, the enhanced fireproof layer 5 is made of stainless steel material, and a plurality of transverse reinforcing ribs 5-4 and two longitudinal reinforcing ribs 5-3 (two in this embodiment, and other quantities are also possible) are provided on the upper layer 5-1.

[0021] As Figure 2 , 3 shown, a T-shaped block 6 is provided on one outer wall (either the left side or the right side) of the main body plate frame 1, and a T-shaped slot 7 is correspondingly formed on the other outer wall of the main body plate frame 1. The shape of the T-shaped slot 7 matches that of the T-shaped block 6, so that the T-shaped block 6 can be embedded into the T-shaped slot 7 of another main body plate frame 1 to realize the splicing between two main body plate frames 1.

[0022] Preferably, the T-shaped block 6 is fixed to the main body plate frame 1 by welding. After the T-shaped block 6 is embedded into the T-shaped slot 7 of another main body plate frame 1, the sides of the two main body plate frames 1 are flush with each other.

[0023] As Figure 1 shown, the sound absorption and noise reduction layer 3 is a perforated plate structure made of composite foam material, and the cavity 3-1 of the perforated plate is used to form a resonance effect to effectively absorb sound.

[0024] The assembly process of the present utility model: During assembly, the buffer layer 2 is first fitted in the main body plate frame 1 as a bottom plate. The sound absorption and noise reduction layer 3 is adhesively connected to the top of the buffer layer 2, and the waterproof layer 4 is adhesively connected to the top of the sound absorption and noise reduction layer 3. The sound absorption and noise reduction layer 3 significantly improves the sound absorption and noise reduction ability through the resonance sound absorption structure of the perforated plate. The lower layer 5-2 of the enhanced fireproof layer 5 is embedded into the fitting groove 1-1 of the main body plate frame 1 and pressed on the waterproof layer 4, and at the same time, the upper layer 5-1 is exposed from the fitting groove 1-1, as Figure 3 shown. The enhanced fireproof layer 5 is made of stainless steel. The arrangement of the longitudinal reinforcing ribs 5-3 and the transverse reinforcing ribs 5-4 can effectively improve the stability of the overall structure, improve the high-temperature resistance of the fireproof layer, and thus enhance the fireproof performance of the entire fireproof rock wool board.
