Description

Technical Field

[0001] This utility model relates to building insulation materials, specifically to an inorganic panel composite silicon graphene insulation building structural component. Background Technology

[0002] Statistics show that the total energy consumption and carbon emissions of buildings throughout their entire life cycle account for about 50% of the nation's total energy consumption and carbon emissions. In traditional buildings, heat loss through the building envelope reaches as high as 70% to 80%. Ultra-low energy buildings and zero-carbon buildings reduce heat loss through the building envelope by 60% compared to existing buildings. Developing ultra-low energy buildings and zero-carbon buildings is of great significance for achieving building energy conservation and the "dual carbon" goals.

[0003] Currently, traditional exterior wall insulation systems have limited functionality, struggling to balance insulation with fire resistance, waterproofing, and weather resistance, resulting in significant durability issues and high overall energy consumption. Low-carbon, energy-saving integrated structural insulation building envelope systems can achieve the same lifespan as the main structure. However, suitable insulation materials and components that balance safety, durability, and functionality are lacking, and the application of formwork-free integrated structural insulation systems in buildings presents challenges such as difficulty in controlling flatness. Utility Model Content

[0004] This utility model provides an inorganic panel composite silicon graphene thermal insulation building structural component. The inorganic panel composite silicon graphene thermal insulation building structural component is installed on the outer surface of the building's outer perimeter wall using a number of anti-loosening bolts. The anti-loosening bolts penetrate the inorganic panel composite silicon graphene thermal insulation building structural component and are embedded in pre-formed holes in the building's outer perimeter wall. The front section of the anti-loosening bolt in the pre-formed hole has external threads, and the rear section in the inorganic panel composite silicon graphene thermal insulation building structural component has a number of wing-shaped anti-loosening barbs.

[0005] The inorganic panel composite silicon graphene thermal insulation building structural component consists of an outer inorganic panel layer, an adhesive layer, and an inner thermal insulation material layer, stacked sequentially from the outside to the inside in the thickness direction.

[0006] The outer inorganic panel layer is 5–12 mm thick and has a density ≥1.4 g / cm³. 3 Fiber-reinforced cement board or calcium silicate board;

[0007] The bonding layer uses a 0.8–2 mm thick polymer-modified inorganic adhesive and incorporates an alkali-resistant glass fiber mesh, with a unit area mass ≥100 g / m². 2 ;

[0008] The internal insulation layer uses 60-200mm thick silicon graphene foam boards with a density of 180-260kg / m³. 3 Thermal conductivity ≤0.028W / m·K.

[0009] Furthermore, the inorganic panel composite silicon graphene thermal insulation building structural component is provided with several countersunk holes coaxial with the pre-formed holes, and the anti-loosening bolt passes through the countersunk holes and is connected to the building's outer perimeter wall.

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0022] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0023] Reference Figure 1 As shown, the inorganic panel composite silicon graphene thermal insulation building structural component provided by this utility model is fixed to the outer surface of the building's outer perimeter wall 1 using several anti-loosening bolts 5, thereby forming an external thermal insulation protective layer for the building. From the perspective of the specifications of a single component, the maximum length of a single inorganic panel composite silicon graphene thermal insulation building structural component is set at 1.2m, and the maximum width at 2.4m. This facilitates hoisting and handling during construction, avoiding difficulties in construction operations due to excessively large components. It also effectively reduces the number of splicing gaps between structural components during construction, lowering the risk of subsequent problems such as decreased thermal insulation performance and water seepage caused by improper gap treatment. Furthermore, it is compatible with the modular design of most building exterior walls, improving construction efficiency and overall aesthetics.

[0024] The anti-loosening bolt 5 penetrates the entire inorganic panel composite silicon graphene thermal insulation building structure and is embedded in the pre-formed hole pre-processed inside the building's outer perimeter wall 1, so as to firmly install the thermal insulation building structure on the outer surface of the building's outer perimeter wall 1 and prevent safety hazards such as detachment and displacement caused by external forces (such as wind force and temperature stress) during long-term use.

[0025] The inorganic panel composite silicon graphene thermal insulation building structure of this utility model consists of an outer inorganic panel layer 2, an adhesive layer 3, and an inner thermal insulation material layer 4, which are stacked sequentially from the outside to the inside.

[0026] As the outer protective structure of the structural components, the external inorganic panel layer 2 is directly exposed to the outdoor environment and must possess excellent wind pressure resistance, weather resistance, impact resistance, and fire resistance. Therefore, fiber-reinforced cement board or calcium silicate board are selected as the two types of inorganic boards for its selection. The thickness of the external inorganic panel layer 2 is controlled within the range of 5-12mm. This ensures that the panel has sufficient structural strength to withstand external forces such as collisions and abrasions in the outdoor environment, while avoiding an increase in the overall weight of the structural components due to excessive thickness, which would reduce the load-bearing capacity of the wall. At the same time, the density of the board is required to be ≥1.4g / cm³. 3This further improves the density of the panel and reduces porosity, thereby enhancing its waterproof and impermeable capabilities, preventing rainwater and moisture from penetrating into the internal insulation layer and affecting its insulation performance, and extending the service life of the structural components.

[0027] The specific performance parameters of the outer inorganic panel layer 2 are as follows:

[0028]

[0029] The adhesive layer 3 serves as a transitional layer between the outer inorganic panel layer 2 and the inner insulation material layer 4, ensuring tight adhesion between the two layers and preventing interlayer delamination. It also provides some crack resistance and waterproofing. Therefore, the adhesive layer 3 uses a 0.8–2 mm thick polymer-modified inorganic adhesive. This type of adhesive, through polymer modification technology, significantly improves its flexibility and bonding strength while retaining the fire-retardant and high-temperature resistant properties of inorganic adhesives. It can effectively adapt to temperature stress caused by differences in the thermal expansion coefficients of different materials, reducing the risk of interlayer cracking. Furthermore, the adhesive layer 3 also incorporates an alkali-resistant glass fiber mesh, with a mesh area mass ≥100 g / m². 2 High-density alkali-resistant glass fiber mesh can form a three-dimensional mesh support structure, further enhancing the crack resistance and overall tensile strength of the adhesive layer, preventing the generation and propagation of cracks, and resisting the erosion of the adhesive layer by alkaline substances in the external environment, ensuring the long-term stable bonding effect of the adhesive layer.

[0030] The inner insulation layer 4 uses graphene foam board, which is modified from traditional foam insulation materials by introducing graphene components, combining thermal insulation performance with strength. The thickness of the inner insulation layer 4 is set at 60-200mm, which can be adjusted according to the building energy-saving design standards of different regions (such as severely cold regions, cold regions, hot-summer-cold-winter regions, etc.) to meet the requirements of different climatic regions for the heat transfer coefficient of the building envelope; the density is controlled at 180-260kg / m³. 3 This design ensures that the foam board forms a uniform, closed-loop bubble structure, effectively blocking heat transfer, while also guaranteeing that the material has a certain compressive strength to prevent deformation and collapse due to pressure during construction, installation, or long-term use. Its key performance indicator, thermal conductivity ≤0.028W / m·K, is far lower than traditional insulation materials (such as ordinary polystyrene board with a thermal conductivity of approximately 0.039W / m·K), significantly reducing heat loss from the building's exterior walls, improving the building's energy efficiency, and contributing to the achievement of ultra-low energy consumption and zero-carbon building construction goals.

[0031] The specific performance parameters of the inner insulation material layer 4 are as follows:

[0032]

[0033]

[0034] In an optional embodiment, to further optimize the installation stability and waterproof sealing performance of the structural components, several countersunk holes are pre-processed on the inorganic panel composite silicon graphene insulation building structural components. The axis of the countersunk holes is completely coincident with the axis of the pre-formed holes on the building's outer perimeter wall 1, ensuring that the anti-loosening bolts 5 can smoothly pass through the countersunk holes and accurately embed into the pre-formed holes, achieving coaxial positioning connection between the structural components and the wall. Simultaneously, the countersunk holes are filled with sealant covering the anti-loosening bolts 5. This sealant is selected from silicone sealant or polyurethane sealant with excellent weather resistance, waterproofing, and adhesion. Its main functions are twofold: first, to seal the gap between the countersunk holes and the anti-loosening bolts 5, preventing outdoor rainwater, moisture, dust, and other impurities from seeping into the interior of the structural components or the wall through the gap, avoiding problems such as moisture-induced failure of the internal insulation material and corrosion of the wall reinforcement; second, to protect the anti-loosening bolts 5, preventing them from rusting due to long-term exposure to the outdoor environment by ultraviolet rays and rainwater, extending the bolt's service life, and ensuring the long-term stability of the connection structure.

[0035] In an optional embodiment, considering the stress characteristics and connection requirements of different building wall materials (such as concrete walls, masonry walls, etc.), the anti-loosening bolt 5 is selected as a chemical anchor. The chemical anchor consists of a screw, a chemical adhesive tube (or putty), and other components. The installation process involves first inserting the chemical adhesive tube into a pre-drilled hole in the wall, then inserting and rotating the screw. A chemical reaction occurs between the chemical adhesive tube, the screw, and the hole wall, forming a high-strength bonded anchoring system. Compared to traditional expansion bolts, chemical anchors have advantages such as high anchoring force, good fatigue resistance, and minimal damage to the wall substrate. They are particularly suitable for building insulation structural components with high anchoring strength requirements, ensuring that the structural components maintain a stable connection with the wall even under strong winds, earthquakes, and other external forces during long-term use, significantly improving the safety and reliability of the building envelope system.

[0036] In an optional embodiment, to further enhance the connection strength between the anti-loosening bolt 5 and the building's exterior wall cladding 1 and structural components, and to prevent the bolt from loosening or coming off, the anti-loosening bolt 5 adopts the following special structure: the front section of the bolt located in the pre-drilled hole in the building's exterior wall cladding 1 (i.e., the part in contact with the wall) is provided with an external thread 51. The external thread structure can form a mechanical engagement with the chemical adhesive tube (or wall substrate) in the pre-drilled hole, increasing the mechanical anchoring force on the basis of chemical bonding, and further improving the connection strength between the bolt and the wall; while the bolt is located on the inorganic panel The rear section (i.e. the part in contact with the structural component) of the composite silicon graphene thermal insulation building structural component has several wing-shaped anti-loosening barbs 52 evenly arranged on both sides of its outer diameter. These anti-loosening barbs are made of elastic material or rigid protrusion structure. When the bolt penetrates the structural component, the anti-loosening barbs will embed into the inner thermal insulation material layer 4 or the adhesive layer 3 to form a one-way locking structure, which effectively prevents the bolt from loosening or coming out under the influence of factors such as vibration and temperature changes. From the structural design, the anti-loosening effect of the bolt connection is doubly guaranteed, ensuring the long-term stability of the connection between the structural component and the wall.

[0037] Furthermore, a wire mesh is embedded within the inner insulation material layer 4. This wire mesh is woven from hot-dip galvanized steel wire, possessing excellent rust resistance and tensile strength. Its mesh size can be set according to the thickness and strength requirements of the inner insulation material layer (typically 50mm×50mm or 100mm×100mm), and the wire diameter is generally 0.8–1.2mm. The wire mesh forms a uniform supporting skeleton within the insulation layer, distributing external forces throughout the entire insulation layer, effectively improving its compressive and flexural strength, and reducing cracking and deformation caused by excessive localized stress. Simultaneously, the wire mesh enhances the bond between the insulation layer and the adhesive layer 3, preventing peeling between them, further ensuring the integrity and stability of the structural components and extending their service life.

[0038] The thermal insulation building structure consists of an outer inorganic panel, an adhesive layer, and an inner insulation layer, arranged from the outside in. Its advantages include: high-quality inorganic panels offer good flexibility and volume stability (flexural strength ≥10MPa, moisture expansion rate ≤0.15%); the adhesive layer uses cement mortar; and the inner insulation layer uses graphene insulation material, which boasts advantages such as Class A fire resistance, low thermal conductivity (thermal conductivity ≤0.052W / (m·K)), and high tensile and bending strength (vertical tensile strength >0.20MPa, bending load >3000N). It also exhibits good compatibility with cement-based materials. Furthermore, the raw materials are readily available, resulting in low project costs. This eliminates the need for external insulation construction procedures, shortens the construction period, and allows for large-scale implementation.
