[0030] Please refer to the reference. Figures 1 to 3 According to an embodiment of the present invention, the waterproof and heat-insulating structure of the roof 1 includes a roof 1 and an insulation layer 3. An eaves gutter 11 is provided at the edge of the roof 1. The insulation layer 3 covers the roof 1. A first drainage groove 31 and a second drainage groove 32 are provided on the side of the insulation layer 3 facing the roof 1. The extension directions of the first drainage groove 31 and the second drainage groove 32 are intersected. Both the first drainage groove 31 and the second drainage groove 32 are connected to the eaves gutter 11.

[0031] According to the waterproof and thermal insulation structure of the roof 1 in this embodiment of the present invention, by opening a first drainage channel 31 and a second drainage channel 32 at the bottom of the thermal insulation layer 3, the accumulated water in the thermal insulation layer 3 can be drained from the first drainage channel 31 and the second drainage channel 32 to the eaves gutter 11 for centralized drainage. Thus, there is no need to install drainage pipes (holes) on the roof 1, the waterproof layer remains continuous, and damage to the waterproof layer of the roof 1 is avoided. The first drainage channel 31 and the second drainage channel 32 are arranged in intersecting directions to achieve multi-angle drainage, improving drainage efficiency and effectively preventing the thermal insulation efficiency from decreasing after water accumulates in the thermal insulation layer 3.

[0032] In practice, the roof 1 can be laid with traditional waterproof materials (such as waterproof membrane or waterproof coating) to ensure the basic waterproof performance of the roof 1. The insulation layer 3 is covered with materials with good thermal insulation properties (such as polystyrene foam board or rock wool board) on the roof 1 to provide heat insulation and thermal insulation functions.

[0033] The insulation layer 3 has a first drainage channel 31 and a second drainage channel 32 on the side facing the roof 1. The first drainage channel 31 and the second drainage channel 32 can be designed as rectangular channels, triangular channels, or other suitable shapes, and their depth and width can be adjusted according to actual needs. The extension directions of the first drainage channel 31 and the second drainage channel 32 are intersecting. For example, the first drainage channel 31 extends longitudinally along the roof 1, and the second drainage channel 32 extends laterally along the roof 1, forming a grid-like drainage system. The ends of the first drainage channel 31 and the second drainage channel 32 are connected to the eaves gutter 11 to ensure that rainwater can be smoothly discharged into the eaves gutter 11.

[0034] In actual installation, the insulation layer 3 can be fixed to the roof 1 by adhesive or mechanical fastening. The first drainage channel 31 and the second drainage channel 32 can be formed on the insulation layer 3 by cutting or molding. The eaves gutter 11 is opened at the edge of the roof 1, and the eaves gutter 11 has a groove structure to facilitate centralized drainage.

[0035] When rainwater falls on the roof 1, it flows down the slope of the roof 1 to the surface of the insulation layer 3. Furthermore, the first drainage channel 31 and the second drainage channel 32 at the bottom of the insulation layer 3 guide the water condensed within the insulation layer 3 to the intersection point, and through the connecting design of the intersection point, direct the water into the eaves gutter 11. After collecting the rainwater, the eaves gutter 11 discharges the water from the roof 1 through drainage pipes or downspouts, preventing rainwater from accumulating on the roof 1.

[0036] According to one embodiment of this utility model, the first drainage channel 31 and the second drainage channel 32 are arranged perpendicularly to each other in their extending directions. For example, the insulation layer 3 consists of multiple insulation boards, which are laid on the roof 1. The dimensions of the insulation boards are: length 1800mm * width 600mm * thickness 80mm. Specifically, a first drainage channel 31, 50mm wide and 40mm deep, is formed every 600mm along the length of the insulation board, and a second drainage channel 32, 50mm wide and 40mm deep, is formed at the midpoint of the width direction.

[0037] According to one embodiment of the present invention, the insulation layer 3 has a plurality of first drainage grooves 31, which are spaced apart laterally along the insulation layer 3; optionally, the insulation layer 3 has a plurality of second drainage grooves 32, which are spaced apart longitudinally along the insulation layer 3. It can be understood that the number of first drainage grooves 31 and second drainage grooves 32 can be adjusted according to the actual size of the insulation layer 3 to improve the drainage effect.

[0038] According to one embodiment of this utility model, a drainage notch 33 is provided at the bottom edge of the insulation layer. It is understood that providing a clear drainage channel for water by creating a downward-facing semi-groove-shaped drainage notch 33 at the edge of the insulation layer prevents water from accumulating at the edge of the insulation layer. This structure is similar to a drainage trough, guiding water smoothly out and reducing the time water remains inside the insulation layer. Simultaneously, it reduces the risk of leakage, as water can be drained promptly, lowering the risk of leakage due to water accumulation. This design effectively protects the insulation layer and the base layer, especially in environments with heavy rainfall or high humidity. Furthermore, the drainage notch 33 can better integrate with the base layer or other insulation boards, forming a unified whole. This design improves the stability of the insulation system and reduces the risk of insulation boards loosening or falling off due to water accumulation.

[0039] According to one embodiment of this utility model, the waterproof and thermal insulation structure of the roof 1 includes a first drainage pipe 8, which is located at the edge of the insulation layer 3 and connects to a first drainage channel 31 and an eaves gutter 11. The roof 1 also includes a second drainage pipe, located at the edge of the insulation layer 3 and connecting to a second drainage channel 32 and an eaves gutter 11. It is understood that the first drainage pipe 8 can collect water flowing out of the first drainage channel 31 and guide it into the eaves gutter 11, preventing water from seeping into the surrounding area and thus helping to prevent water accumulation in the insulation layer 3. Similarly, the second drainage pipe can collect water flowing out of the second drainage channel 32 and guide it into the eaves gutter 11, preventing water from seeping into the surrounding area and thus helping to prevent water accumulation in the insulation layer 3.

[0040] According to one embodiment of this utility model, the first drain pipe 8 is bent and extends towards the bottom of the eaves gutter 11. In this way, the water collected by the first drain pipe 8 can flow out towards the bottom of the eaves gutter 11. Furthermore, the outlet of the first drain pipe 8 can be positioned near the bottom wall of the eaves gutter 11 to reduce the distance between the outlet and the bottom wall, thus preventing water from splashing to other areas and improving the waterproofing effect. Simultaneously, the downward-facing outlet of the first drain pipe 8 helps prevent other debris from entering and causing blockages, ensuring its drainage effect.

[0041] Optionally, the second drain pipe is bent and extends towards the bottom of the eaves gutter 11. This allows water collected in the second drain pipe to flow out towards the bottom of the eaves gutter 11. Furthermore, the outlet of the second drain pipe can be positioned near the bottom wall of the eaves gutter 11 to reduce the distance between the outlet and the bottom wall, preventing water from splashing to other areas and improving waterproofing. Simultaneously, the downward-facing outlet of the second drain pipe helps prevent debris from entering and clogging it, ensuring effective drainage.

[0042] According to one embodiment of the present invention, the waterproof and thermal insulation structure of the roof 1 includes a first waterproof layer 2, which is disposed between the thermal insulation layer 3 and the roof 1. For example, the first waterproof layer 2 is preferably constructed as a coating waterproof layer, which can fully adhere to the concrete structure of the roof 1, effectively preventing water leakage.

[0043] According to one embodiment of this utility model, the waterproof and thermal insulation structure of the roof 1 includes a first concrete protective layer 4, which is disposed on the side of the insulation layer 3 facing away from the roof 1. It is understood that the main function of the first concrete protective layer 4 is to protect the waterproof layer and insulation layer 3 from environmental factors such as ultraviolet radiation, ozone, acids, and alkalis, and to prevent damage to the waterproof layer and insulation layer 3 by external forces. This is crucial for extending the service life of the waterproof layer and insulation layer 3. The first concrete protective layer 4 provides a robust surface capable of withstanding various loads that the roof 1 may experience, such as foot traffic and equipment placement, thereby protecting the underlying waterproof layer and insulation layer 3 from damage.

[0044] According to one embodiment of this utility model, a water-retaining curb 5 is provided at the edge of the first concrete protective layer 4, and the water-retaining curb 5 stops at the edge of the insulation layer 3. It is understood that the water-retaining curb 5 wraps around the edge of the insulation layer 3. It should be noted that the water-retaining curb 5 has an avoidance opening to avoid the first drainage channel 31 and the second drainage channel 32, thereby preventing the water from the first drainage channel 31 and the second drainage channel 32 from draining out. At the same time, the water-retaining curb 5 can prevent water draining from the first drainage channel 31 and the second drainage channel 32 from seeping into the edge of the insulation layer 3, which helps to prevent water accumulation in the insulation layer 3.

[0045] According to one embodiment of the present invention, the first concrete protective layer 4 is provided with a steel mesh to prevent the first concrete protective layer 4 from cracking due to temperature changes.

[0046] According to one embodiment of this utility model, the waterproof and thermal insulation structure of the roof 1 includes a second waterproof layer 6, which is laid on the first concrete protective layer 4. Exemplarily, the second waterproof layer 6 can be laid to the inner wall of the eaves gutter 11, and the edges of the second waterproof layer 6 can be fixed to the side wall of the eaves gutter 11 or the roof 1 by metal strips 9 and cement nails 10 to improve installation stability. As the outermost waterproof barrier of the roof 1 system, the second waterproof layer 6 can effectively prevent rainwater or other moisture from penetrating into the first concrete protective layer 4 and the thermal insulation layer 3. The second waterproof layer 6 is typically made of polymer waterproof membrane or waterproof coating, which has good durability and weather resistance.

[0047] Optionally, a second concrete protective layer 7 is also provided on the second waterproof layer 6. The second concrete protective layer 7 provides a solid surface that can withstand various loads that the roof 1 may be subjected to, such as people walking and equipment placement, thereby protecting the lower second waterproof layer 6 and insulation layer 3 from damage.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
