[0035] The following descriptions of each embodiment refer to the accompanying drawings to exemplify specific embodiments in which the present utility model can be implemented.

[0036] As Figure 1 , Figure 2 and Figure 3 shown, this embodiment discloses a floor thermal insulation and sound insulation structure, which includes a floor fireproof, thermal insulation and sound insulation board. The floor fireproof, thermal insulation and sound insulation board includes a thermal insulation layer 1 and a sound insulation layer 2. The thermal insulation layer 1 is made of A-level fireproof and thermal insulation materials, and the sound insulation layer 2 is made of rubber particles. The raw material composition of the A-level fireproof and thermal insulation materials of the thermal insulation layer 1 is disposed on the sound insulation layer 2, so that the sound insulation layer 2 and the thermal insulation layer 1 are integrally formed, and the sound insulation layer 2 is located below the thermal insulation layer 1.

[0037] During the preparation of the floor fireproof, thermal insulation and sound insulation board, the sound insulation layer 2 is pre-laid on the bottom of the mold, and then the raw material composition of the A-level fireproof and thermal insulation materials is disposed above the sound insulation layer 2, so as to realize that the thermal insulation layer 1 is connected above the sound insulation layer 2 and integrally formed, making the floor thermal insulation and sound insulation structure take into account both the functions of thermal insulation and sound insulation; and the structural connection strength is high and the stability is high. At the same time, the thermal insulation layer 1 is made of A-level fireproof and thermal insulation materials, effectively enhancing the fireproof and thermal insulation effects of the floor fireproof, thermal insulation and sound insulation board.

[0038] The floor thermal insulation and sound insulation structure further includes a concrete floor slab 10 and a concrete protective layer 20. The concrete floor slab 10, the floor fireproof, thermal insulation and sound insulation board, and the concrete protective layer 20 are arranged in sequence from bottom to top, so that the sound insulation layer 2 is located between the thermal insulation layer 1 and the concrete floor slab 10, ensuring better sound insulation performance of the sound insulation layer 2; the concrete protective layer 20 is connected to the thermal insulation layer 1 and plays a protective role for the floor fireproof, thermal insulation and sound insulation board, ensuring the thermal insulation and sound insulation effects of the floor thermal insulation and sound insulation structure. Among them, the concrete floor slab 10 can be integrally cast or precast and combined with in-situ casting.

[0039] There is an adhesive layer between the concrete floor slab 10 and the sound insulation layer 2. Through the adhesive layer, the connection strength between the concrete floor slab 10 and the floor fireproof, heat-insulating and sound-insulating board can be effectively enhanced, and the stability is higher. Among them, the adhesive layer can be composed of mortar.

[0040] The total thickness of the heat-insulating layer 1 and the sound insulation layer 2 is 20 - 60 mm, and the thickness of the sound insulation layer 2 is 3 - 20 mm. By the thickness of the sound insulation layer 2, an effective sound insulation effect can be ensured, and by the total thickness of the heat-insulating layer 1 and the sound insulation layer 2, an effective sound insulation effect and heat insulation effect can be ensured. Preferably, the total thickness of the heat-insulating layer 1 and the sound insulation layer 2 is 30 - 50 mm, and the thickness of the sound insulation layer 2 is 3 - 15 mm.

[0041] Among them, the rubber particles constituting the sound insulation layer 2 can be waste rubber particles, achieving the environmental protection and energy-saving effect of solid waste utilization.

[0042] During the preparation process of the floor fireproof, heat-insulating and sound-insulating board, there can be a pressurizing process on the raw material composition, and the compression coefficient is 1 - 3, making the heat-insulating layer 1, the sound insulation layer 2 and the interface between the heat-insulating layer 1 and the sound insulation layer 2 denser.

[0043] There is at least one first strengthening structure 3 arranged in the heat-insulating layer 1. By arranging the first strengthening structure 3 in the heat-insulating layer 1, the strength of the floor fireproof, heat-insulating and sound-insulating board can be effectively enhanced, and the rigid strength and crack prevention effect of the heat-insulating layer 1 can be improved. Among them, the number of the first strengthening structures 3 can be not limited.

[0044] The first strengthening structure 3 can be a reinforcing mesh. The material of the first strengthening structure 3 is fiberglass mesh, metal mesh, FRP mesh or carbon glass mesh, further enhancing the strength of the floor fireproof, heat-insulating and sound-insulating board. Among them, FRP mesh is Fiber Reinforced Polymer / Plastic (abbreviated as FRP).

[0045] The material of the heat-insulating layer 1 is an A-level fireproof organic-inorganic composite heat-insulating material. Through the heat-insulating performance of the A-level fireproof organic-inorganic composite heat-insulating material, it can ensure that under the condition of the same thickness of the heat-insulating material, the strength meets the requirements of relevant product standards, and it can take into account both the fireproof and heat-insulating effects. Under the condition of reaching A-level fireproof, a better heat-insulating effect can be achieved. Preferably, the organic material in the A-level fireproof organic-inorganic composite heat-insulating material is polystyrene particles.

[0046] The material of the heat-insulating layer 1 is graphene heat-insulating material. It effectively guarantees the heat-insulating performance and fireproof performance of the floor fireproof, heat-insulating and sound-insulating board, and greatly improves the safety and stability of the floor fireproof, heat-insulating and sound-insulating board.

[0047] A groove is provided on one side of the thermal insulation layer 1 facing away from the sound insulation layer 2; and / or, a groove is provided on one side of the sound insulation layer 2 facing away from the thermal insulation layer 1. By providing grooves on one or both sides of the floor fireproof, thermal insulation and sound insulation board, the raw materials of the concrete floor slab 10 and the concrete protective layer 20 will flow into the grooves and be connected to the floor fireproof, thermal insulation and sound insulation board, thereby increasing the connection strength between the floor fireproof, thermal insulation and sound insulation board and the concrete floor slab 10 and the concrete protective layer 20.

[0048] A second strengthening structure 30 is embedded in the concrete protective layer 20. By arranging the second strengthening structure 30 in the concrete protective layer 20, the strength of the floor thermal insulation and sound insulation structure can be effectively enhanced, and the rigid strength and anti-cracking effect of the concrete protective layer 20 can be improved. Among them, the number of the second strengthening structures 30 may not be limited.

[0049] The second strengthening structure 30 can be a metal mesh. By embedding a metal mesh as the strengthening structure in the concrete protective layer 20, the concrete material can form a whole to prevent cracking.

[0050] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of the rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
