Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a prefabricated thermal insulation and soundproof composite floor slab. Background Technology

[0002] In the construction industry, traditional floor slabs have shortcomings in terms of thermal insulation and soundproofing. For example, ordinary concrete floor slabs have a high thermal conductivity, making it difficult to effectively block the exchange of heat between indoors and outdoors. This results in rapid heat loss from indoors in winter and a large influx of outdoor heat in summer, increasing building energy consumption. At the same time, their ability to block impact noise and airborne noise is limited, affecting the comfort of residents. This is especially true in buildings with high acoustic requirements, such as residences, schools, and hospitals, where poor floor sound insulation can easily lead to problems such as neighborhood disputes.

[0003] During use, concrete floor slabs are prone to cracking due to factors such as temperature changes, concrete shrinkage, and uneven foundation settlement. Cracks not only affect the aesthetics of the floor slab but can also lead to steel reinforcement corrosion, reducing the slab's durability and structural safety. Traditional floor slabs often lack adequate crack-resistant measures, making it difficult to fundamentally solve the cracking problem. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated thermal insulation and soundproof composite floor slab. The closed-cell foam plastic cavity can effectively reduce heat conduction, reduce indoor and outdoor heat exchange, and reduce building energy consumption. The sound-absorbing panel cavity absorbs sound energy. The tight connection between each layer reduces sound leakage through gaps, which can effectively improve the ability to block airborne sound and impact sound. The crack-resistant layer buffers stress, protects the internal structure, reduces cracks, and extends the service life of the floor slab. The interlayer connection is firm, and the tongue and groove connection enhances the integrity and stability, effectively transmits and bears the load, and ensures building safety.

[0005] To achieve the above objectives, this utility model provides a prefabricated thermal insulation and soundproof composite floor slab, including a floor slab body, which includes a base layer, a thermal insulation and soundproof layer, a crack-resistant layer, and a surface layer.

[0007] Preferably, the thermal insulation and sound insulation layer is fixedly connected to the base layer by anchors, with the anchors placed inside the thermal insulation and sound insulation layer.

[0008] Preferably, the thermal insulation and sound insulation layer includes a sound-absorbing panel cavity, and closed-cell foam plastic cavities are fixedly connected to the upper and lower sides of the sound-absorbing panel cavity.

[0023] Example one

[0024] As shown in Figure 1 The utility model provides a kind of assembled heat preservation and sound insulation composite floor, including floor body, and floor body is connected by tenon and mortise connection mode between, tenon and mortise connection mode is used to connect between floor body, it is with adjacent floor body can be closely spliced, guarantee the continuity and flatness of floor whole, this connection mode not only facilitates construction installation, improves construction efficiency, and can enhance the integrity and stability of floor splicing, so that the whole floor can work in coordination when being stressed, jointly bear load.Floor body includes base layer 1, heat preservation and sound insulation layer 2, anti-crack layer 3 and surface layer 4, and base layer 1 is fixedly connected between heat preservation and sound insulation layer 2, heat preservation and sound insulation layer 2 is fixedly connected with anti-crack layer 3, and anti-crack layer 3 is fixedly connected with surface layer 4.

[0025] The base layer 1 is a honeycomb structure and is a base supporting structure of the floor slab, providing initial bearing capacity for the whole floor slab, bearing the use load from the upper structure and transmitting it to the lower structure. This structure form not only guarantees certain strength, but also reduces the weight of the base layer 1 itself and saves materials. The honeycomb holes can also play a buffering and sound-absorbing role to a certain extent, assisting in improving the heat and sound insulation performance of the floor slab. The surface layer 4 is a reinforced concrete layer and is a grid-shaped reinforcing rib structure. The surface layer 4 is the uppermost layer of the floor slab and directly bears various loads in the use process, such as personnel walking, furniture placement, etc., to provide a stable use platform for the indoor. The concrete material has high strength and durability, which can ensure the safety and reliability of the floor slab in the long-term use process. The grid-shaped reinforcing rib structure further enhances the bearing capacity of the surface layer 4. Through the arrangement of the ribs, the surface layer 4 can also bear a large load under a smaller thickness, improving the mechanical properties of the structure. At the same time, the grid-shaped structure helps to disperse stress and reduce the possibility of cracks in the surface layer 4.

[0026] The anti-cracking layer 3 includes a cement layer 31 and an alkali-resistant layer 32. The cement layer 31 is fixedly connected with the surface layer 4, and the alkali-resistant layer 32 is fixedly connected with the cement layer 31 on one side and the heat and sound insulation layer 2 on the other side. The cement layer 31 is tightly connected with the surface layer 4, plays a bonding role, and makes the surface layer 4 firmly combined with the anti-cracking layer 3. At the same time, the cement layer 31 has certain flexibility and ductility, which can buffer the stress of the surface layer 4 due to temperature changes, concrete shrinkage and other factors, and prevent the surface layer 4 from cracking. The alkali-resistant layer 32 is fixedly connected with the cement layer 31 on one side and the heat and sound insulation layer 2 on the other side, playing a role of protecting the heat and sound insulation layer 2. Since the concrete and other materials may contain alkaline substances, the alkali-resistant layer 32 can prevent the erosion of alkaline substances on the material of the heat and sound insulation layer 2, prolong the service life of the heat and sound insulation layer 2, and enhance the stability of the connection between the anti-cracking layer 3 and the heat and sound insulation layer 2.

[0027] The heat and sound insulation layer 2 is fixedly connected with the base layer 1 through anchor nails. The anchor nails are placed inside the heat and sound insulation layer 2, firmly fixing the heat and sound insulation layer 2 and the base layer 1 together, ensuring that the heat and sound insulation layer 2 will not be separated from the base layer 1 due to external forces (such as vibration, temperature change, etc.) during the use of the floor slab, and ensuring the stability of the whole floor slab structure and the normal play of the heat and sound insulation function.

[0028] The sound insulation and heat preservation layer 2 comprises an acoustic panel cavity 21, and the main function of the acoustic panel cavity 21 is to absorb and block sound, and the acoustic panel cavity 21 converts the sound energy into other forms of energy (such as heat energy) through the special structure and material of the acoustic panel, so that the sound transmission capacity of the floor is reduced, and the sound insulation effect is achieved. The upper and lower sides of the acoustic panel cavity 21 are fixedly connected with closed-cell foam plastic cavities 22, and the acoustic panel cavity 21 and the closed-cell foam plastic cavities 22 are fixedly connected through connecting columns. The closed-cell structure of the closed-cell foam plastic cavities 22 has good heat preservation and insulation performance, can effectively prevent heat from being transmitted through the floor, reduce the heat exchange between the indoor and outdoor, and play a heat preservation role; meanwhile, the closed-cell foam plastic has certain elasticity and buffering property, which is helpful to further enhance the sound insulation effect of the floor. The connecting columns are used for connecting the acoustic panel cavity 21 and the closed-cell foam plastic cavities 22 on the upper and lower sides, so as to ensure the stability and integrity of the overall structure of the sound insulation and heat preservation layer 2, and make the parts work cooperatively.

[0029] In use of the assembled heat preservation and sound insulation composite floor, according to the design requirements, the composite panel layer with the honeycomb structure is made as the base layer 1 by using a specific process, after the manufacturing is completed, the acoustic panel cavity 21 and the closed-cell foam plastic cavities 22 on the upper and lower sides are fixedly connected through the connecting columns to form the sound insulation and heat preservation layer 2 assembly. The anchor nails are installed at specific positions of the sound insulation and heat preservation layer 2 assembly, and the anchor nails need to be partially arranged in the sound insulation and heat preservation layer 2 and used for subsequent connection with the base layer 1. After the assembly is completed, the cement layer 31 and the alkali-resistant layer 32 materials are prepared respectively, and the reinforced concrete layer with the grid-shaped reinforcing rib structure is made as the surface layer 4, so that the assembled heat preservation and sound insulation composite floor is obtained.

[0030] Therefore, the assembled heat preservation and sound insulation composite floor is adopted, the closed-cell foam plastic cavities can effectively reduce heat conduction, reduce the heat exchange between the indoor and outdoor, reduce the building energy consumption, the acoustic panel cavity absorbs sound energy, the layers are tightly connected to reduce the sound leakage through the gaps, the blocking capacity for the air sound and the impact sound can be effectively improved, the anti-cracking layer buffers stress, protects the internal structure, reduces the cracks, prolongs the service life of the floor, the interlayer connection is firm, the rabbet connection enhances the integrity and stability, the load can be effectively transmitted and borne, and the building safety is ensured.
