[0002] With the acceleration of urbanization, the construction industry's demand for efficient, energy-saving, and environmentally friendly materials is increasing. Traditional building materials often struggle to balance thermal insulation, sound insulation, and structural performance, necessitating the separate installation of insulation layers, soundproofing layers, and structural support systems during construction. This not only increases construction costs and time but may also affect building quality and durability due to material compatibility issues.

[0003] Currently, floor decking materials on the market are mainly divided into reinforced concrete slabs, steel plates, and composite panels. While these materials meet the basic structural requirements of buildings to a certain extent, they have the following limitations in terms of thermal insulation, sound insulation, and overall performance: Traditional floor decking often uses a single material, making it difficult to provide effective thermal insulation and resulting in insufficient thermal insulation performance. It requires the addition of an additional sound insulation layer, which not only increases the complexity of construction but may also affect the aesthetics. The stacking of multiple materials requires multiple processes, extending the construction period. In addition, it is difficult to guarantee the bonding performance between different materials and the overall structural strength.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0022] This utility model provides an integrated thermal insulation and soundproofing foamed ceramic composite floor deck structure, which, from top to bottom, includes a steel truss, a precast base slab 4, an adhesive layer 5, an insulation layer 6, a reinforcing layer 7, and a foamed ceramic panel 8. The steel truss includes an upper chord steel bar 1, a lower chord steel bar 2, and web reinforcement 3. The web reinforcement 3 connects the upper chord steel bar 1 and the lower chord steel bar 2. The lower chord steel bar 2 is partially embedded in the precast base slab 4. The precast base slab 4 and the insulation layer 6 are compositely fixed by the adhesive layer 5, and the insulation layer 6 and the foamed ceramic panel 8 are compositely fixed by the adhesive layer 5. This integrated thermal insulation and soundproofing foamed ceramic composite floor deck structure integrates thermal insulation and soundproofing functions, improving the building's energy efficiency and aesthetics. The steel truss structure enhances the overall load-bearing capacity, and the multi-layer structure design improves overall stability and durability. The combination of the precast base slab 4 and the steel truss enhances structural strength, and the adhesive layer 5 ensures a firm connection between the layers.

[0023] Specifically, the foamed ceramic panel 8 has a reinforcing layer 7 on both sides. The reinforcing layer 7 includes any one of a glass fiber mesh layer, a steel wire mesh layer, a carbon fiber mesh layer, and polymer fibers. Glass fiber mesh is a commonly used reinforcing material that can improve the crack resistance and overall strength of the structure; steel wire mesh provides additional structural strength and stability; carbon fiber mesh is lightweight and high-strength, significantly improving the tensile strength of the structure; polymer fibers, including polypropylene or polyethylene fibers, can increase the toughness of the structure. By providing the reinforcing layer 7, the strength and durability of the foamed ceramic panel 8 are further enhanced, reducing the risk of cracking and breakage.

[0024] Specifically, the thickness of the precast base slab 4 does not exceed 20mm. The precast base slab 4 provides sufficient structural strength, optimizes the overall weight, and facilitates construction and installation. The total thickness of the insulation layer 6 and the foamed ceramic board 8 is 20~60mm, which ensures sufficient insulation effect while controlling the overall thickness, saving space, and reducing the overall weight of the building.

[0025] Specifically, the integrated thermal insulation and soundproofing foamed ceramic composite floor deck structure also includes anchoring connectors 9, pre-embedded fixing holes 10, or pre-embedded internally threaded sleeves 10. The pre-embedded internally threaded sleeves 10 are threadedly connected to the anchoring connectors 9, and the pre-embedded fixing holes 10 are internally filled with UHPC to connect to the anchoring connectors 9. The anchoring connectors 9 enhance the connection strength between layers, improving the stability and safety of the overall structure. The pre-embedded fixing holes 10 or pre-embedded internally threaded sleeves 10 protect the anchoring connectors 9 and improve aesthetics.

[0026] Specifically, the adhesive layer 5 is a rebar adhesive layer, epoxy resin adhesive layer, polyurethane adhesive, or bonding mortar used for tensile bonding. The rebar adhesive is an epoxy-based rebar adhesive or a water-based epoxy rebar adhesive, possessing high adhesion and strength, capable of bonding the precast base slab 4 and the insulation layer 6. The epoxy resin adhesive is a two-component or multi-component adhesive that forms a robust adhesive layer 5 through a chemical reaction between epoxy resin and a curing agent. It exhibits excellent bonding strength, chemical resistance, and durability, suitable for bonding various building materials, including metals, glass, and ceramics. Using a tensile bonding rebar adhesive layer or an epoxy resin adhesive layer as the adhesive layer 5 provides strong tensile and adhesion forces, helping to ensure the stability and durability of the overall slab, reducing deformation or deterioration caused by temperature changes, thereby extending its service life.

[0027] Specifically, the insulation layer 6 is any one of aerogel, graphite composite board, graphene insulation board, polystyrene foam, polyurethane foam layer, and rock wool. The insulation layer 6 provides good thermal insulation, thereby improving the building's energy efficiency. Preferably, the insulation layer is aerogel, which has Class A fire resistance and sound insulation properties. The insulation layer 6 has excellent properties such as low thermal conductivity, thermal insulation, fire resistance, and sound insulation, giving the structure good sound insulation performance and a low heat transfer coefficient, with a K-value ≤ 1.0, meeting energy-saving and environmental protection requirements.

[0028] Specifically, the foamed ceramic board 8 includes any one of lightweight foamed ceramic board, nanoporous foamed ceramic board, porous foamed ceramic board, and composite foamed ceramic board, with a K value ≤ 1.0, meeting energy-saving and environmental protection requirements. Furthermore, the foamed ceramic board 8 also has sound insulation properties, giving both the insulation layer 6 and the foamed ceramic board 8 excellent performance such as low thermal conductivity, thermal insulation, and good sound insulation. This results in better sound insulation performance and a lower heat transfer coefficient, with a K value ≤ 1.0, meeting energy-saving standards and giving the foamed ceramic composite floor deck structure excellent thermal insulation and sound insulation effects.

[0029] In summary, the integrated thermal insulation and soundproofing foamed ceramic composite floor deck structure provided by this utility model achieves integrated sound insulation and thermal insulation functions by introducing foamed ceramic panels and an insulation layer with excellent thermal insulation performance. The design of the steel truss and reinforcing layer enhances the overall strength and stability of the floor deck, enabling it to withstand larger loads and ensuring the strength and durability of the overall structure. The combination of the insulation layer and the foamed ceramic panels provides good thermal insulation, effectively reducing building energy consumption. The design of the precast base plate and bonding layer makes the installation process simpler and faster, reducing on-site construction time and costs. The materials used, such as the foamed ceramic panels and reinforcing layer materials (such as glass fiber and carbon fiber), have good durability and corrosion resistance, extending the service life of the floor deck. The integrated thermal insulation and soundproofing foamed ceramic composite floor deck structure provided by this utility model can reduce the complex process of traditional multi-layer material stacking, shorten the construction cycle, and is suitable for different building types and application scenarios, with broad market application prospects.
