[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] This embodiment provides a sound insulation and vibration damping composite panel installed on a reinforced concrete floor slab, such as... Figures 1-3 As shown, it includes a fine stone concrete layer 1, a cement perlite fiberboard layer 2, a graphite polystyrene board layer 3, and a rubber pad layer 4 connected in sequence. The rubber pad layer 4 is attached to the upper surface of the reinforced concrete floor slab; if the composite board is located inside the building wall, the rubber pad layer 4 is attached to the inner wall surface.
[0030] In this embodiment, the fine aggregate concrete layer 1 is formed by mixing fine aggregate and concrete. The fine aggregate concrete mixture has a high density and is relatively heavy. Its complete structure effectively blocks the transmission of sound waves. Furthermore, the density of the fine aggregate concrete mixture causes sound waves to be reflected and absorbed during propagation, resulting in significant attenuation. Therefore, the fine aggregate concrete layer 1 has excellent noise reduction and sound insulation properties.
[0031] In this embodiment, the cement-perlite fiberboard layer 2 is formed by mixing fibers, perlite, cement, and water. Cement serves as the main binder, providing the basic structure and strength of the board. Perlite, through its unique structure and high-temperature expansion properties, increases the fire resistance of the board. The addition of fibers further enhances the toughness and integrity of the board, making it less prone to collapse during earthquakes and fires, thus providing better protection. In high-temperature environments, the fire-retardant properties of perlite help improve the fire resistance of the floating floor slab, further enhancing its fire resistance, while also providing flame retardancy. Simultaneously, the porous structure is beneficial for absorbing and isolating noise, providing good sound insulation.
[0032] In this embodiment, the graphite polystyrene board layer 3, in addition to its thermal insulation function, also has excellent sound insulation properties. The rubber pad layer 4, with its superior elasticity, can effectively absorb and disperse impact forces, reducing the impact of vibration on the structure. It also has sound absorption capabilities and can effectively isolate heat conduction between the internal and external environments.
[0033] This embodiment also includes a wire mesh layer 5 and several evenly arranged tie rods 6. The wire mesh layer 5 is embedded in the fine stone concrete layer 1. The tie rods 6 tie the wire mesh layer 5, the cement perlite fiberboard layer 2, the graphite polystyrene board layer 3 and the rubber pad layer 4 into one unit. The cement perlite fiberboard layer 2 in this embodiment is also provided with steel wire ribs 7 arranged in a crisscross pattern.
[0034] In this embodiment, the steel wire mesh layer 5, tie rod 6, and steel wire rib 7 can completely and stably combine the fine stone concrete layer 1, cement perlite fiberboard layer 2, graphite polystyrene board layer 3, and rubber pad layer 4 into a whole, improving the stability of the floating floor slab. The tight connection of each part also further increases the vibration reduction and sound insulation effect.

The wire mesh frame layer is formed by welding multiple wire mesh sheets to the protruding ends of the web wire 8. The wire mesh sheets used in the wire mesh frame layer are 50X50X2.0 mm in size. The strength of the fine stone concrete layer 1 is C25, and the density of the cement perlite fiberboard layer 2 is 500. .
[0043] The wire mesh is 50X50X2.0mm, meaning the mesh size is 50mm x 50mm and the wire diameter is 2.0mm.
[0044] Example 5
[0045] Based on the above embodiments, the cement perlite fiberboard layer in this embodiment is formed by laying cement perlite fiberboard. The cement perlite fiberboard has a specification of 600×600×20mm, and each cement perlite fiberboard has 8 steel wire ribs embedded in it both longitudinally and transversely.
