Common roof structures can be divided into flat roofs and pitched roofs. Existing flat building roofs are usually made of a single material such as concrete, metal or brick. Such roofs have poor waterproof and heat insulation performance during use. Traditional roof waterproof and heat insulation structures are relatively complex, with high construction costs and difficult maintenance, so it is necessary to make improvements. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a waterproof, heat-insulating, and thermally insulating roof for buildings, thereby effectively improving the waterproof and heat-insulating performance of the roof and facilitating its construction.

[0020] Composite waterproof membrane layer 1 Base Layer 10: Base Layer 10 is the bottom layer structure of the composite waterproof membrane layer 1, directly contacting the roof surface and undertaking the dual functions of "basic waterproofing" and "supporting the upper structure". Base Layer 10 uses conventional and mature waterproof substrates, specifically selected from styrene-butadiene-styrene (SBS) modified bitumen, thermoplastic polyolefin (TPO), and polyvinyl chloride (PVC). All of the above materials have excellent weather resistance, tensile strength, and basic waterproofing capabilities, and can adapt to the roofing needs of different climatic environments (high temperature, low temperature, and heavy rainfall). The connection method between the base layer 10 and the roof surface is dynamically adjusted according to the roof surface material. If the roof surface is a porous or easily bonded substrate such as concrete or plywood, an adhesive connection is used (the adhesive is a silane-terminated polymer compatible with the subsequent adhesive layer 13 to avoid interlayer chemical reactions). If the roof surface is a smooth or difficult-to-bond substrate such as metal, glass, or photovoltaic panels, a mechanical connection is used (fixed to the roof joists with stainless steel self-tapping screws, with waterproof gaskets covering the screw heads to prevent local water seepage). Meanwhile, the base layer 10 is prefabricated in roll form, requiring only on-site cutting and laying according to the roof dimensions, significantly improving construction efficiency and solving the problems of long construction cycles and high pollution associated with traditional on-site pouring of waterproof layers (such as asphalt layers). Oil migration prevention layer 11: Oil migration prevention layer 11 is applied to the upper surface of the base layer 10 and is made of acrylic coating. In the prior art, the plasticizers, antioxidants and other oily additives contained in the base layer 10 (such as SBS modified bitumen, PVC) will slowly migrate to the surface during long-term use. If they come into direct contact with the adhesive layer 13, it will cause the adhesive to "swell with oil", resulting in problems such as yellowing, cracking and reduced bonding strength, and ultimately causing the waterproof membrane to delaminate and seep into the water. The acrylic coating has a dense molecular structure with high cross-linking density between its molecular chains, forming a "physical barrier" that blocks the migration path of oily additives inside the base layer 10 to the adhesive layer 13. This coating can reduce oil migration by more than 90%. The oil migration prevention layer 11 is applied using a combined "roller coating + scraper coating" process. First, roller coating ensures uniform coverage of the substrate 10 surface (thickness controlled at 0.1-0.2mm; no dimensional verification is required, only the process logic is explained). Then, scraper coating is used to treat seams, edges, and other easily missed areas of the substrate 10, ensuring no pores or breaks, forming a continuous oil-proof barrier. Simultaneously, the acrylic coating exhibits excellent compatibility, showing no chemical reaction with the substrate 10 (SBS / TPO / PVC) or the subsequent adhesive layer 13 (moisture-curing adhesive). It adheres stably to the surface of the substrate 10, is resistant to UV aging, and shows no chalking or peeling even after long-term use. Adhesive layer 13: Adhesive layer 13 is disposed between the oil migration prevention layer 11 and the composite surface layer 12. Its function is to firmly bond the composite surface layer 12 to the oil migration prevention layer 11, forming an integrated structure of "base layer 10 - oil migration prevention layer 11 - composite surface layer 12", avoiding the risk of water seepage caused by interlayer peeling. Adhesive layer 13 uses a moisture-curing adhesive, specifically one selected from silane-terminated polymers and polymethyl methacrylate (PMMA). Moisture-curing adhesives only need to absorb moisture from the air to complete the curing process, without the need for solvents, making them environmentally friendly and pollution-free; moreover, the curing conditions are flexible, and it can be stably cured within the range of 5-40℃ and 30%-90% humidity, making it suitable for construction sites with different climates. The adhesive layer 13 is applied using a combination of spot coating and strip coating. On the upper surface of the oil migration-resistant layer 11, strip coating (10-15cm wide, no dimensional verification required) is applied along the seams of the base layer 10 roll material to ensure strong adhesion at the seams. For the remaining areas, spot coating (20-30cm spacing between dots) is used, ensuring adhesion strength while reducing adhesive usage and lowering costs. Simultaneously, after the adhesive layer 13 is applied, the composite surface layer 12 must be laid within the "open time" (a characteristic indicator of moisture-curing adhesives, typically 30-60 minutes) to prevent the adhesive surface from curing and affecting the bonding effect. Composite Surface Layer 12: Composite surface layer 12 is the top layer 34 structure of composite waterproof membrane layer 1, which is in direct contact with the upper heat insulation layer 2. It undertakes the functions of "protecting the underlying structure" and "enhancing the overall strength of the waterproof membrane". It is composed of a cap layer and reinforcing materials. Cap Layer: As the outer layer of composite surface layer 12, it directly contacts the external environment (such as rain, ultraviolet rays, and mechanical impact). It is made of a material with excellent weather resistance and abrasion resistance, specifically TPO, PVC, SBS, and PMMA. TPO material has excellent resistance to ultraviolet aging and is suitable for high-temperature, high-UV areas; PVC material has good chemical corrosion resistance and is suitable for industrial building roofs; SBS material has excellent low-temperature flexibility and is suitable for cold regions. Users can choose flexibly according to their application scenarios. Reinforcing material: Embedded inside the cap layer, its function is to enhance the tensile strength and tear resistance of the composite surface layer 12, solving the problems of traditional waterproof membranes being "easily punctured by sharp objects" and "easily cracked due to thermal expansion and contraction." The reinforcing material can be selected from woven fabric, non-woven fabric, mesh, or loosely woven fabric—woven fabric (such as polyester woven fabric) has high tensile strength and is suitable for high-load roofs; non-woven fabric (such as polyester non-woven fabric) has good flexibility and is suitable for curved or irregularly shaped roofs; mesh (such as fiberglass mesh) has strong alkali resistance and is suitable for use with concrete roofs. The composite surface layer 12 is firmly connected to the oil migration prevention layer 11 through the adhesive layer 13. The oil migration prevention layer 11 blocks the migration of oil from the base layer 10, ensuring the long-term stability of the adhesive layer 13. The base layer 10 is fixed to the roof surface through an adaptation method. The four-layer structure forms a "continuous and non-porous" waterproof barrier.

[0021] Thermal insulation layer 2 Buffer bottom layer 30: Buffer bottom layer 30 is the bottom layer of thermal insulation unit 3, which is in direct contact with composite waterproof membrane layer 1. It is made of silicone and is cross-shaped. Silicone has excellent elasticity and compression resistance, and can expand and contract synchronously with the slight deformation of the roof to avoid stress concentration between layers. At the same time, the buffering performance of silicone can absorb the trampling load, reduce the impact of the upper structure on composite waterproof membrane layer 1, and protect the waterproof membrane from damage. There are two ways to connect the buffer base layer 30 to the composite waterproof membrane layer 1: conventional bonding: using a special silicone adhesive (compatible with the material of the buffer base layer 30 to avoid chemical reaction), after applying it to the lower surface of the buffer base layer 30, it is directly laid on the composite waterproof membrane layer 1, which is suitable for flat roofs; direct laying + edge limiting: no bonding is required, the buffer base layer 30 is placed directly on the composite waterproof membrane layer 1, and the overall limiting is achieved by the metal pressure strip (mechanical fixation) at the edge of the roof, which is suitable for curved surfaces or temporary roof modifications, and is easy to disassemble and replace later. The upper surface of the buffer layer 30 is provided with a first connecting part 31 for connecting with the intermediate layer 32. The first connecting part 31 is a snap-fit ​​strip or interlocking strip structure, which can be a cross-shaped strip with a protruding end. The strip is cross-shaped and coincides with the center line of the cross of the buffer layer 30. A protruding end is provided at the top of the strip (the size of the protruding end is larger than the size of the strip and extends along the length of the strip), forming a snap-fit ​​structure. A strip groove 36 is opened at a corresponding position on the lower surface of the intermediate layer 32. The positioning connection between the buffer layer 30 and the intermediate layer 32 is achieved by the snap-fit ​​of the protruding end and the strip groove 36, avoiding lateral displacement. It can also be a grid-shaped strip with a protruding end. There are four strips, which are arranged in a cross shape (grid shape). Compared with the cross-shaped strip, the grid-shaped strip has a larger contact area and stronger connection stability, which is suitable for roofs with large loads (such as roof gardens and photovoltaic roofs). Similarly, a grid-shaped strip groove 36 is opened on the lower surface of the intermediate layer 32 to snap-fit ​​with the strip. The first connecting part 31 and the buffer bottom layer 30 are made of the same material (both are silicone), which can be integrally molded to avoid breakage of the connecting part; the elasticity of silicone can ensure that it still has a certain deformation ability after being embedded, and adapt to small displacements between layers.

[0022] Intermediate layer 32: The intermediate layer 32 is laid on the upper surface of the buffer bottom layer 30 and is fixed to the buffer bottom layer 30 by the first connecting part 31. It is made of ceramic thermally conductive material and is cross-shaped. Its core functions are "basic heat insulation" and "carrying flow path 4 temperature control system", achieving the dual effect of "passive heat insulation + active temperature control". Passive insulation principle: Ceramic material itself has a low thermal conductivity (usually ≤0.15W / (m・K)), which can effectively block the transfer of external heat to the interior of the building (in summer) or the loss of heat from the interior of the building to the outside (in winter). Its basic insulation performance is better than that of traditional foam plastics (such as EPS, XPS) - foam plastics are prone to aging and shrinkage after long-term use, which leads to a decrease in insulation performance, while ceramic material is resistant to aging and high temperature (can withstand temperatures above 100℃), and has stable long-term insulation performance. Active temperature control carrier function: The intermediate layer 32 has a built-in flow path 4, which is distributed in a cross shape and has openings on all four end faces of the intermediate layer 32 (for easy connection between units). The flow path 4 is the core channel for realizing active temperature control, and its design details are as follows: Flow path 4 structure: The flow path 4 is a hollow channel opened inside the intermediate layer 32, with a circular or rectangular cross-section (circular channels have low fluid resistance, and rectangular channels are easier to process). The cross-shaped distribution ensures that the flow path 4 covers the entire area of ​​the intermediate layer 32, achieving uniform temperature control; Opening adaptation: The opening of the flow path 4 can be connected to a connecting pipe or a sealing plug—when multiple When the thermal insulation unit 3 is spliced, the openings of the flow path 4 of adjacent units are connected by a connecting pipe (a conventional double-ended connecting pipe, made of heat-resistant plastic or metal) to form a continuous network of flow paths 4. When the unit is located at the edge of the roof or does not need to be connected, it is sealed with a sealing plug (made of silicone and with an interference fit to the opening of the flow path 4) to prevent the medium in the flow path 4 from leaking. The ceramic material has good thermal conductivity (compared to the buffer bottom layer 30 and the top layer 34), which can quickly transfer the temperature of cold / hot water in the flow path 4 to the entire roof, improve the temperature control efficiency, and solve the limitation of traditional passive thermal insulation that "cannot adjust the temperature". Top Layer 34: Top layer 34 is laid on the upper surface of intermediate layer 32 and connected to intermediate layer 32 through second connecting part 33. It is made of flexible glass fiber and is cross-shaped. Its core functions are "protecting intermediate layer 32" and "supporting lighting unit". Protecting the intermediate layer 32: The flexible fiberglass material has excellent tensile strength, corrosion resistance and wear resistance, which can effectively protect the intermediate layer 32 (the ceramic material is brittle and easily damaged by sharp objects), avoiding mechanical damage during construction or maintenance; at the same time, the flexible fiberglass has good air permeability, which can expel moisture from the inside of the roof (such as water vapor after rainwater seepage), preventing moisture from accumulating between the composite waterproof membrane layer 1 and the thermal insulation layer 2, which can lead to mold and adhesion failure. Lighting carrier function: The upper surface of the top layer 34 is provided with a fitting groove 5, which is a cross shape distributed concentrically with the top layer 34. It is used to fit the light strip to achieve integrated lighting. Its design details are as follows: Fitting groove 5 structure: The fitting groove 5 is a groove opened on the upper surface of the top layer 34. The cross-section is "U". The width and depth of the groove are adapted to the size of the light strip (no specific size is required, only the standard light strip specifications need to be matched). The cross-shaped distribution can ensure that the light strip lighting covers the main area of ​​the roof, and it works in conjunction with the cross structure of the heat insulation unit 3, which is aesthetically pleasing. Preferably, the inner wall of the fitting groove 5 is attached with a silicone anti-slip pad, which can fix the position of the light strip and prevent the light strip from shifting when the roof vibrates (such as in strong winds); at the same time, the outside of the light strip can be covered with a transparent waterproof cover (made of polycarbonate material, UV resistant) to prevent rainwater and dust from entering the interior of the light strip and extend the service life of the light strip. The second connecting part 33 is the connection structure between the top layer 34 and the intermediate layer 32. The second connecting part 33 is a T-shaped strip, composed of a web and a wing. The bottom end of the web is connected to the upper surface of the intermediate layer 32, and the wing is horizontally set at the top of the web (forming a "T" shape). The second connecting part 33 and the intermediate layer 32 are made of the same material (ceramic) and can be integrally formed with the intermediate layer 32, resulting in high connection strength and no risk of breakage. A "reverse T" T-shaped groove 37 is opened at the corresponding position on the lower surface of the top layer 34. The position and contour of the T-shaped groove 37 are perfectly matched with the second connecting part 33. Through the interlocking of the T-shaped strip and the T-shaped groove 37, a firm connection between the top layer 34 and the intermediate layer 32 is achieved, which is also convenient for disassembly. When the top layer 34 or the intermediate layer 32 is damaged, it can be replaced simply by separating it along the interlocking direction without destroying the entire unit, thus solving the problem of "partial damage requiring overall replacement" in traditional integral insulation layers. Cover plate 35: Cover plate 35 is a supplementary structure after the thermal insulation unit 3 is spliced ​​together. It is installed in the square groove formed by splicing several thermal insulation units 3 (when several cross-shaped units are spliced ​​together, a square gap is formed between the cross arms of adjacent units, i.e., the square groove). Its core functions are "covering the splicing seam" and "improving the flatness of the roof". The cover plate 35 adopts a three-layer composite structure of "ceramic thermal conductive layer + aluminum foil layer + fiberglass layer", with each layer functioning synergistically: Ceramic thermal conductive layer (bottom layer): Made of the same material as the middle layer 32, it can synchronize the temperature transferred by the flow path 4, avoiding temperature differences between the cover plate 35 and the middle layer 32 and reducing thermal bridging effect; at the same time, the lower surface of the ceramic thermal conductive layer is attached to the inner wall of the square groove and fixed with silicone adhesive to ensure a firm connection; Aluminum foil layer (middle layer 32): Aluminum foil has high reflectivity and can reflect external ultraviolet and infrared rays, reducing heat absorption (in summer) and further improving heat insulation performance; at the same time, the aluminum foil layer has good sealing properties, which can prevent rainwater and dust from entering the interior of the square groove; Fiberglass layer (top layer 34): Made of the same material as the top layer 34 (flexible fiberglass), it can ensure that the cover plate 35 and the top layer 34 have consistent flatness, improve the overall aesthetics of the roof, and the wear resistance of the fiberglass layer can extend the service life of the cover plate 35. The modular design (several units spliced ​​together) of the thermal insulation layer 2 is the key innovation of this invention, and it has the following advantages compared with the traditional integral thermal insulation layer: Simple construction: The units are prefabricated, and on-site construction only requires cutting (standard cross-shaped units + special-shaped cutting units) according to the roof size, splicing and fixing. No on-site pouring or complex processing is required, which improves construction efficiency by more than 50%. Low maintenance cost: When a local unit is damaged (such as cracking of the middle layer 32 or damage to the top layer 34), only the corresponding unit needs to be replaced, without the need for complete dismantling, reducing maintenance costs by more than 70%. High adaptability: Through special cutting (such as triangular and trapezoidal units), it can be adapted to irregular roof shapes such as circles and polygons, solving the limitation of traditional integral insulation layers that "only apply to rectangular roofs"; Highly scalable: If the heat insulation performance needs to be improved later, units of the same specifications can be stacked on top of the existing units (fixed by additional connecting parts); if photovoltaic panels need to be added, photovoltaic brackets can be laid directly on the top layer 34 and the cover plate 35 without damaging the original structure. Hot and cold water supply unit The hot and cold water supply unit provides hot / cold water medium to flow path 4, and a conventional hot and cold water supply unit (such as a commercial air source heat pump or an electric heating / cooling integrated unit) is selected: The hot and cold water supply unit can integrate a temperature sensor, a controller, and a remote module. The temperature sensor is installed on the top floor of the roof (to monitor the roof temperature in real time) and inside the building (to monitor the indoor temperature in real time). The controller automatically adjusts the operation of the supply unit according to preset temperature thresholds (e.g., supplying cold water when the indoor temperature is ≥26℃ in summer and supplying hot water when the indoor temperature is ≤18℃ in winter). The remote module can be remotely controlled via a mobile APP or the building's central control system (e.g., turning off when leaving home, preheating / precooling before returning home), improving ease of use. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
