[0003] In rural areas of my country, flat roofs are common, leading to high indoor temperatures, especially during the hot summer months when strong sunlight makes the heat unbearable for residents and disrupts their daily lives. Many families add an insulation layer to their roofs, typically consisting of several insulation units, each made of concrete formwork and supported by four legs. While this provides some insulation, the effect is not significant, and the flat roof design makes it prone to water accumulation. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Refer to Figures 1 to 3 A thermal insulation roof suitable for flat roofs includes a cement slab 1. The upper end of the cement slab 1 is provided with an installation groove 2. Multiple main water guiding slopes 5 are longitudinally spaced in the installation groove 2. Multiple pairs of branch water guiding slopes 6 are symmetrically arranged in the installation groove 2 about the main water guiding slopes 5. The end of the main water guiding slope 5 closest to the drainage hole 7 is the lowest, and the end of each branch water guiding slope 6 closest to the main water guiding slope 5 is the lowest, so that rainwater can flow from the branch water guiding slopes 6 to the main water guiding slope 5 under its own gravity, and finally flow through the main water guiding slope 5 to the drainage hole 7 to be discharged from the roof.

[0023] Multiple assembly grooves are formed between the main water guiding slope 5 and the branch water guiding slope 6. Assembly blocks 3 are set in the assembly grooves. Heat insulation cavities are opened in the assembly blocks 3. Polystyrene foam boards 11 are set in the heat insulation cavities. Polystyrene foam boards 11 (EPS boards) have the advantages of being lightweight, inexpensive, having low thermal conductivity, low water absorption, good electrical insulation, sound insulation, shock absorption, moisture resistance, and simple molding process. Moreover, due to its air-filled pore structure, it has a low thermal conductivity and good thermal insulation performance. In addition, polystyrene foam boards 11 also have excellent impact resistance and low water absorption, which can maintain the stability of material performance.

[0024] A drainage gap 4 is formed between multiple assembly blocks 3. Multiple drainage holes 7 connected to the installation groove 2 are opened on the cement plate 1. From bottom to top, the cement plate 1 is provided with a heat insulation layer 8, a sound insulation layer 9, and a waterproof layer 10. The heat insulation layer 8 is filled with a high-temperature resistant fiberboard made of mineral fibers and organic adhesives. Under high temperature, the high-temperature resistant fiberboard is not prone to shape changes or thermal expansion and contraction, maintaining its structural integrity. For example, the fiber cement board can withstand temperatures up to 1000℃ under normal use conditions. In addition, due to the presence of cellulose fibers and cement, the high-temperature resistant fiberboard has good fire resistance and can effectively prevent the spread of flames. The high-temperature resistant fiberboard also has a low thermal conductivity, which can reduce heat conduction and provide good heat insulation effect.

[0025] The sound insulation layer 9 is made of polyurethane foam. Polyurethane foam has a porous structure. As a new type of sound insulation material, polyurethane foam is lightweight, efficient and easy to construct. It absorbs sound waves through its porous structure to achieve a sound insulation effect.

[0026] Waterproof layer 10 uses sprayed polyurethane foam, which contains fiberglass mesh. Sprayed polyurethane foam is a high-performance building material with many superior properties. First, it has excellent waterproof performance. Rigid polyurethane foam is a new type of synthetic material with both thermal insulation and waterproofing functions. It has a low thermal conductivity, the lowest among thermal insulation materials. In addition, the closed-cell rate of polyurethane foamed on-site reaches over 90%, providing excellent waterproofing and preventing moisture erosion. Continuous construction results in no splicing cracks, maintaining a seamless and integrated appearance. Sprayed polyurethane foam performs excellently in terms of thermal insulation. Furthermore, it is an excellent thermal insulation material with a low thermal conductivity, effectively blocking thermal bridges and ensuring the interaction between the insulation material and the wall, thus providing a long-lasting insulation effect. Sprayed polyurethane foam also has wide applicability and multifunctionality. It can be used for various purposes such as sealing leaks, filling gaps, and fixing and bonding. It is suitable for sealing and waterproofing between PVC or aluminum alloy doors and windows and walls. Because it contains fiberglass mesh material, the cured foam has strong adhesion and shockproof and pressure-resistant properties, ensuring a sturdy and durable structure.

[0027] Each assembly block 3 has a groove 12 at its upper end, and a green plant pot 13 is placed in the groove 12. The inner circumferential wall of the groove 12 is fixedly bonded with a sealing rubber gasket. The green plant pot 13 is interference-fitted with the groove 12 through the sealing rubber gasket to prevent rainwater from entering the groove 12. In addition, the interference fit between the green plant pot 13 and the groove 12 through the sealing rubber gasket ensures the stability of the green plant pot 13. By planting green vegetation on the roof, a natural heat insulation effect is provided, the heat island effect is reduced, the aesthetics are increased, biodiversity is promoted, and air quality is improved.

[0028] The working principle of this utility model is as follows:

[0029] This utility model divides the roof into multiple assembly blocks 3 and forms drainage gaps 4 between each assembly block 3. When there is water on the roof, it will flow to the drainage gaps 4. Then, under its own gravity, the rainwater flows from the branch water guiding slope 6 to the main water guiding slope 5, and finally flows through the main water guiding slope 5 to the drainage hole 7 to be discharged from the roof.

[0030] The cement slab 1 contains, in sequence, an insulation layer 8, a sound insulation layer 9, and a waterproof layer 10. These layers are constructed from high-temperature resistant fiberboard, polyurethane foam, and sprayed polyurethane foam, respectively. In addition to their respective insulation, sound insulation, and waterproofing properties, these materials all have low thermal conductivity, reducing heat transfer and providing excellent insulation for the roof. Furthermore, planting green vegetation on the roof provides natural insulation, reducing the heat island effect. Combined with the polystyrene foam board in assembly block 3, which is lightweight, inexpensive, has low thermal conductivity, low water absorption, good electrical insulation, sound insulation, shock absorption, moisture resistance, and simple molding process, its air-filled porous structure further ensures excellent roof insulation performance due to its low thermal conductivity.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
