[0002] Fiber cement board is a building board made of cement as the basic material, combined with adhesives and mineral fibers or other reinforcing fibers, through processes such as pulping, molding, and curing.

[0003] Chinese Patent Publication No. CN220117638U discloses a sound-absorbing and sound-insulating composite fiber cement board, relating to the field of building materials technology. It includes a first mounting shell, a second mounting shell on the left side of the first mounting shell, and cement boards inside both the first and second mounting shells. Sound insulation cavities and sound insulation mechanisms are formed within both cement boards. Sound-absorbing holes are formed on both sides of the first and second mounting shells, and mounting mechanisms are provided on the outer surfaces of both the first and second mounting shells. By setting up the first and second mounting shells and the mounting mechanisms, the composite fiber cement board can be easily and quickly installed using the mounting mechanisms, solving the problem of cumbersome screw installation and improving worker efficiency.
