[0036] As shown in Figures 1 to 5

[0037] The present utility model aims to elaborate the overall technical scheme of the roof in detail, including its basic constituent parts, material selection and characteristics, as well as the design concept and working principle of the whole system, and try to explain it with data or formula as basis.

[0038] I. Basic constituent parts of the roof

[0039] Upper layer plate

[0040] Function: as the outer layer covering of the roof, it bears the functions of sun-shading, rain-proofing and partial heat insulation.

[0041] ​Material selection: polycarbonate board with good light transmittance (light transmittance can reach more than 80%), or light weight and high strength colored metal plate (such as aluminum-zinc alloy plate, reflectivity ≥ 85%), PVC tile with FRP lighting tile (60% ≤ PVC light transmittance ≤ 85%, 75% ≤ FRP lighting plate light transmittance ≤ 90%), Haneng Hanwa combining flexible thin film solar chip with high light transmittance glass (can save energy by 30%), aluminum-manganese tile (corrosion resistance ≥ 25 years), ASA synthetic resin tile (corrosion resistance ≥ 30 years).

[0042] Properties: high light transmittance, weather resistance, impact resistance (polycarbonate board); high reflectivity, decoration (colored metal plate); energy saving, high toughness, wind resistance (PVC tile with FRP lighting tile); high light transmittance, high sealing performance, energy saving (Haneng Hanwa); weather resistance, fire and water resistance, light weight and easy installation (aluminum-manganese tile); environmental protection, high water resistance (ASA synthetic resin tile).

[0043] Lower plate

[0044] Function: as the load-bearing layer and inner layer heat insulation barrier of the roof.

[0045] Material selection: high-strength aluminum alloy plate (yield strength ≥ 200 MPa) or specially treated steel plate (such as galvanized steel plate, corrosion resistance ≥ 15 years), PVC tile with FRP lighting tile (60% ≤ PVC light transmittance ≤ 85%, 75% ≤ FRP lighting plate light transmittance ≤ 90%), Haneng Hanwa combining flexible thin film solar chip with high light transmittance glass (can save energy by 30%), aluminum-manganese tile (corrosion resistance ≥ 25 years), ASA synthetic resin tile (corrosion resistance ≥ 30 years).

[0046] Properties: excellent load-bearing capacity, corrosion resistance, and high light transmittance.

[0047] Hollow layer

[0048] Function: forms a heat insulation barrier to reduce heat transfer. After the airflow enters the hollow part, it carries away the heat on the roof surface and flows out from the roof ridge, effectively releasing the heat on the roof surface to the outside, improving the heat insulation performance of the roof.

[0049] Material selection: thickness 20-200mm high-efficiency thermal insulation materials such as aerogel (thermal conductivity ≤0.01 W / (m·K)), vacuum panel (extremely low thermal conductivity, close to the theoretical limit), polystyrene foam (EPS) (0.033 ≤ thermal conductivity ≤0.044 W / (m·K), extruded polystyrene foam (XPS) (0.027 ≤ thermal conductivity ≤0.035 W / (m·K), rigid polyurethane foam (PU) (0.024 ≤ thermal conductivity ≤0.030 W / (m·K)), mineral wool (thermal conductivity: 0.045 W / (m·K)), expanded perlite (thermal conductivity: 0.027 W / (m·K)), aerated concrete (thermal conductivity: ≤0.22 W / (m·K)), phenolic composite board (thermal conductivity range: 0.022-0.045 W / (m·K)), or air layer of specific thickness (designed according to specific needs).

[0050] Characteristics: extremely low thermal conductivity, effectively blocking heat transfer.

[0051] Connecting column

[0052] Function: through the nested way, realize the close connection and locking between the upper and lower plates, enhance the overall strength of the roof structure.

[0053] Material selection: connecting column elements made of reinforced plastic (such as nylon, polycarbonate, etc.) or metal materials (such as stainless steel, aluminum alloy, etc.) with a diameter of 20-80mm and a height of 20-200mm.

[0054] Characteristics: high-precision processing, ensure the accuracy of geometric shape matching, improve the connection strength and sealing performance.

[0055] Interlocking structure

[0056] Function: realize the close connection and locking between two roof panels or roof plate elements, enhance the overall strength of the roof structure. The hanging tile hook lower surface of the interlocking structure faces inwards and the upper surface faces outwards, which has a unique geometric shape. From the x-axis direction, the hanging tile hook extends along the length direction of the roof slope surface, and the lower surface facing inwards can closely fit with the lower structure to form a relatively closed interlocking space, while the upper surface facing outwards can effectively contact with the upper plate or other covering materials. From the y-axis direction, the hanging tile hook has a certain width, and the lower surface facing inwards can be embedded in the corresponding card slot or groove of the lower structure in this direction, enhancing the lateral connection stability. When the weight of the plate acts on the hanging tile hook, the gravity of the plate can be evenly distributed on the upper surface of the hanging tile hook. Then, through the structure of the hanging tile hook itself, the force is conducted downward along the main part of the hanging tile hook. Because the lower surface of the hanging tile hook faces inwards and interlocks with the lower structure, this part of the structure can effectively transmit the force to the lower plate or the main structure of the building.

[0057] Tile hook

[0058] Function: Reinforced sheet installation, prevent sheet from falling off, improve construction efficiency.

[0059] Material selection: High-strength aluminum alloy (yield strength ≥ 200 MPa), specially treated steel (such as galvanized steel sheet, corrosion resistance life ≥ 15 years), or new light steel keel materials (yield strength ≥ 465 MPa, corrosion resistance life ≥ 50 years), integrated with the lower plate structure.

[0060] Characteristics: Excellent load-carrying capacity, corrosion resistance.

[0061] II. Working principle and design concept

[0062] 1. Working principle:

[0063] Thermal insulation principle: The combination of double-layer plate and hollow layer forms a thermal barrier, effectively blocking the heat transfer path. According to Fourier's heat conduction law Q = -kAΔT / Δx (where Q is the heat flow, k is the thermal conductivity, A is the heat transfer area, ΔT is the temperature difference, Δx is the heat transfer distance), the extremely low thermal conductivity k of the hollow layer material significantly reduces the heat flow Q, thereby achieving excellent thermal insulation effect.

[0064] Structural stability principle: Topological interlocking structure realizes the close connection and locking between roof plate elements through precise geometric shape matching, improving the overall structural strength of the roof. Under the action of external forces such as wind pressure and snow load, the interlocking structure can effectively disperse stress and ensure the safety and stability of the roof structure.

[0065] Construction convenience principle: Modular production method is adopted to prefabricate and standardize the production of roof components. On-site assembly only needs simple operation to complete the installation, greatly improving the construction efficiency and quality. At the same time, the modular design is also convenient for subsequent maintenance and upgrading.

[0066] 2. The role and significance of the hollow plate of the utility model.

[0067] The double-layer hollow plate realizes stronger thermal insulation effect through the internal double-layer structure, preventing excessive conduction of indoor and outdoor heat. The double-layer design not only improves the compressive strength of the plate, but also enhances its sound insulation effect, reducing the interference of rainwater impact and external noise. In addition, the hollow structure reduces the self-weight of the plate, reduces the overall load demand of the roof, and is suitable for various building environments.

[0068] 3. The concept of topological interlocking and its role in the utility model.

[0069] Topology interlocking refers to the method of capturing and detecting information with one or more sensors and analyzing and processing these data through certain algorithms. In this design, topology interlocking refers to the special geometric design of the plates that interlock with each other to form a stable structure without the need for additional adhesives or fasteners. For double-layer hollow plates, the topology interlocking design ensures the close connection between each plate, avoiding displacement or damage of the plates under external forces such as wind load, heavy pressure, or earthquakes. The double-layer hollow structure provides higher structural integrity and durability through interlocking.

[0070] 4. Thickness of hollow plates and natural compatibility with topology interlocking modules

[0071] Double-layer hollow plates have a larger thickness, making them more solid when subjected to external forces, which is highly compatible with the requirements of topology interlocking modules. Topology interlocking design requires modules to have sufficient thickness to ensure that the interlocking effect between adjacent modules can be fully realized. The thicker design of the plates allows them to withstand greater external loads and form a solid overall structure through geometric interlocking. This natural compatibility not only enhances the connection strength between plates, making the structure have stronger compression and shear resistance, but also enhances the heat preservation and sound insulation effect of the plates.

[0072] 5. Effects and significance after forming an overall structure

[0073] Through the topology interlocking structure, multiple modules form a stable overall structure after combination. Such design not only improves the mechanical strength of the structure, but also effectively disperses and absorbs external forces, preventing displacement or damage of individual modules. The overall structure has better durability during construction and long-term use, reducing the frequency of maintenance and replacement. In addition, this modular design has good scalability, facilitating flexible application to different building needs, and reducing material costs and construction complexity.

[0074] 6. Formula basis

[0075] The thermal insulation effect of the double-layer hollow structure can be calculated by the following formula:

[0076]

[0077] where d and d, are the thicknesses of the upper and lower layers of the double-layer hollow plate, respectively. The total thickness d+d, increases the overall thermal insulation capacity.

[0078] According to the basic principles of heat transfer, the hollow layer of the plate can significantly reduce the heat transfer coefficient to achieve thermal insulation. Its heat transfer coefficient can be estimated by the following formula:

[0079]

[0080] where R 空腔R is the thermal resistance of the hollow layer, which depends on the thickness of the air layer and the thermal conductivity of the sheet material. According to experimental data, when the air layer thickness is 12 mm, the economic benefit and practicability are the best, and the overall heat transfer coefficient of the sheet can be reduced by about 30%-50%.

[0081] According to the basic principle of compressive strength, the double-layer design of the sheet can improve its compressive capacity, and the formula is as follows:

[0082]

[0083] Wherein, F is the external force, and A is the stress area of the sheet. The increased thickness d1+d2 helps to disperse the external force and improve the compressive performance.

[0084] 7. Requirements and characteristics of the use area

[0085] The utility model is suitable for the area with various climates, especially the cold area with large temperature difference and the tropical area with high humidity. In the cold area, the hollow design helps to improve the heat preservation performance of the building and reduce the heating energy consumption. In the area with high humidity, the waterproof performance and mildew resistance of the sheet make it more suitable. In addition, in the coastal or mountainous area with strong wind, the topological interlocking structure can better cope with strong wind and typhoon and prevent the sheet from falling off.

[0086] After accurate calculation by using the above three formulas, compared with other types of roof sheet or roof sheet, this design can effectively improve the heat preservation and insulation effect and reduce indoor energy consumption. At the same time, in the area with strong wind and rain and frequent earthquakes, it also shows excellent wind resistance and earthquake resistance. Through simulation analysis by using numerical simulation software, the results show that, compared with the traditional building roof sheet or roof sheet design, the indoor temperature can be reduced by about 3-5℃ in summer, and the air conditioning energy consumption can be reduced by about 20%-30% by using the hollow sheet of the utility model.

[0087] 8. Application of sloping roof building

[0088] The sheet of the utility model is more suitable for use in the sloping roof building, especially the south slope. The south slope usually receives more sunlight, and the hollow structure can effectively slow down the heat transfer, keep the indoor temperature stable, and improve the heat preservation effect in winter. In summer, the thicker double-layer sheet can also effectively block the external heat from entering the indoor, reducing the air conditioning energy consumption. At the same time, the south slope has a large drainage demand, and the topological interlocking structure can better prevent rainwater from penetrating and improve the waterproof effect. For the north slope, since the sunlight is less, the heat preservation effect of the sheet can also effectively reduce the heat loss.

[0089] 9. Material selection

[0090] The utility model recommends using light, durable composite material, such as modified polypropylene, high molecular material, pottery clay material, fiber reinforced plastic, color steel material, cement material or ceramic base material, to ensure the strength and durability of the sheet. In addition, the sheet surface can be added with an ultraviolet-resistant coating to prolong its service life. In humid or cold areas, materials with mildew-proof and anti-freezing properties can also be selected to adapt to local climate conditions.

[0091] Effects of the utility model:

[0092] 1. Significant improvement in thermal insulation effect

[0093] According to tests by third-party professional institutions, compared with traditional single-layer roof structures, the double-layer hollow topology interlocking roof of the utility model can improve the thermal insulation effect by about 20%-30% at noon in summer, effectively reducing the heat accumulation in the room due to solar radiation. In extreme weather conditions, such as when the highest temperature in summer reaches 40℃, the indoor temperature can be reduced by 3-5℃ lower than the outside, significantly improving the indoor thermal environment.

[0094] 2. Significant energy-saving effect

[0095] Due to the significant improvement in thermal insulation performance, the roof system can help buildings reduce air conditioning energy consumption by about 20%-30%, saving energy costs by about 15%-20% on average throughout the year.

[0096] 3. Increase the comfort of human habitation and reduce the indoor temperature of the building

[0097] By effectively reducing the indoor temperature and reducing temperature fluctuations, the roof system provides a more stable and comfortable indoor environment for occupants. According to user feedback surveys, the satisfaction of residents has increased by about 20% compared with traditional roof structures, especially during the summer high-temperature period, residents generally reflect that the indoor environment is cool and pleasant, reducing the discomfort caused by high temperatures.

[0098] 4. Improve the innovation of architectural design

[0099] The double-layer hollow topology interlocking roof of the utility model brings a new idea to architectural design with its unique structural design and advanced material application. Its modular and digital design concept enables architects to fully consider factors such as thermal insulation and energy saving during the design stage, creating both beautiful and practical architectural works. In addition, the roof system also provides rich customization options to meet different architectural styles and functional requirements, enhancing the flexibility and innovation of architectural design.

[0100] 5. Reduce maintenance costs

[0101] The roof system of the utility model adopts high-quality materials and precise manufacturing process, and the durability and anti-aging performance are better than those of traditional roofs. Therefore, during long-term use, the cost caused by maintenance and replacement is reduced. Compared with traditional roofs, the ability to resist typhoons is relatively high, and it is not easy to fall off and be blown away by strong winds, especially in hot coastal areas. At the same time, the modular and easy-to-dismount design also facilitates local maintenance and upgrading, further reducing the difficulty and cost of maintenance.

[0102] 6. Improve the aesthetic and functional properties of buildings: The double-layer hollow topology interlocking roof not only has excellent thermal insulation and energy-saving performance, but also enhances the aesthetic properties of buildings with its unique appearance and structural design. Its smooth lines, delicate details and perfect fusion with modern architectural style make the building more visually striking. In addition, the roof design also fully considers the functional requirements, such as drainage, ventilation, lighting, etc., providing more comprehensive and thoughtful services for buildings. This dual improvement of aesthetics and functionality makes the roof of the utility model an indispensable part of modern architectural design.
