[0048] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0049] The waterproof composite panel 3 and the roofing system 100 according to the present application will be described below with reference to the accompanying drawings.

[0050] like Figure 1 As shown, a specific embodiment of the present application provides a waterproof composite board 3, which is used in a roofing system 100 and includes a base layer 31, a dielectric layer 32 and a waterproof layer 33, wherein the base layer 31 is a hard material part; the dielectric layer 32 is arranged on the surface of the base layer 31; the waterproof layer 33 covers the surface of the dielectric layer 32 away from the base layer 31, the waterproof layer 33 is a polyurea material coating, and the dielectric layer 32 is used to bond the waterproof layer 33 and the base layer 31.

[0051] In the construction of the house structure, multiple waterproof composite panels 3 are spliced ​​together to form the house roof structure. The base layer 31 is a hard material part with high strength. The base layer 31 is used to form the main structure of the roof and bear the upper load. The waterproof layer 33 is a polyurea material coating and is used to spray on the base layer 31 to form the roof waterproof structure. The spraying of the polyurea material coating has high requirements on the surface of the base layer 31: no fingerprint resistance, no oil, and the surface cannot be polished, etc. In the present application, the surface of the base layer 31 is treated by the dielectric layer 32, so as to strengthen the combination of the waterproof layer 33 and the base layer 31 so that the waterproof composite panel 3 forms an integrated component, thereby realizing the simultaneous construction of the main structure of the roof and the roof waterproof structure to shorten the construction period of the house roof structure.

[0052] Specifically, in the prior art, after the main structure of the roof is constructed, a post-construction waterproof layer 33 is required. The post-construction waterproof layer 33 can be made of waterproof coiled material or waterproof coating. When waterproof coiled material is used for construction, multiple hot-melt welding is required to seal and overlap multiple pieces of waterproof coiled material to form a complete post-construction waterproof layer 33. However, hot-melt welding is prone to fall off, warping, and unreliable overlap, resulting in water leakage. When waterproof coating is used for construction, it is necessary to apply it multiple times to reach the designed thickness. In addition, if the waterproof coating is eroded and damaged by extreme weather such as heavy rain, the original waterproof coating needs to be removed and re-applied with a new waterproof coating to avoid bubbling and pinholes after the waterproof coating is cured into a film. Compared with the prior art, the present application uses a waterproof composite board 3 integrating a waterproof layer 33 and a base layer 31 to construct a house roof structure, thereby simplifying the construction process and shortening the construction period.

[0053] In fact, the waterproof composite board 3 is mainly used for the roof structure of industrial plants, and the base layer 31 is a steel plate with high strength. Industrial plants have high requirements for construction period, and the waterproof composite board 3 can be directly laid on the frame of the industrial plant, which is very convenient to install and saves installation time. However, other house structures can also use the waterproof composite board 3, and the base layer 31 can also be made of other hard materials according to the requirements of the house structure.

[0054] It should be noted that, in the specific embodiment of the present application, unless otherwise stated, the waterproof composite board 3 is located above the building structure; and a plurality of waterproof composite boards 3 are spliced ​​together along the left-right direction.

[0055] In some embodiments, the top and bottom surfaces of the base layer 31 are covered with a dielectric layer 32 and a waterproof layer 33 .

[0056] Specifically, the dielectric layer 32 located above is the upper dielectric layer 32, and the dielectric layer 32 located below is the lower dielectric layer 32. The waterproof layer 33 sprayed on the top surface of the upper dielectric layer 32 is the upper waterproof layer 33, and the waterproof layer 33 sprayed on the bottom surface of the lower dielectric layer 32 is the lower waterproof layer 33. By setting the upper waterproof layer 33 and the lower waterproof layer 33, all-round waterproofing is achieved. Once a gap appears in the upper waterproof layer 33 and causes water to enter the base layer 31, at this time, the lower waterproof layer 33 can also seal the water in the waterproof composite board 3, thereby cutting off the leakage path to prevent water from leaking from the waterproof composite board 3 into the house structure, thereby improving the waterproof performance of the waterproof composite board 3.

[0057] The thickness of the waterproof layer 33 ranges from 0.3 mm to 3 mm. A suitable thickness can prevent the thickness of the waterproof composite board 3 from being too large, thereby facilitating the transportation and installation of the waterproof composite board 3. However, the thickness of the waterproof layer 33 can be appropriately increased as needed.

[0058] Furthermore, the waterproof composite board 3 also includes a protective layer 34, which covers the surface of the waterproof layer 33 away from the base layer 31. Generally speaking, it is only necessary to cover the top surface of the upper waterproof layer 33 with the protective layer 34. Since the top surface of the upper waterproof layer 33 is exposed to the external environment, the upper waterproof layer 33 will be damaged under the long-term influence of environmental factors, resulting in water leakage. Among them, the most important environmental factor is long-term exposure to the sun, and the upper waterproof layer 33 will age under ultraviolet radiation. By covering the upper waterproof layer 33 with the protective layer 34, the upper waterproof layer 33 is blocked from long-term contact with the environment, thereby extending the service life of the waterproof composite board 3.

[0059] Preferably, the protective layer 34 is a coating of asparagine polyurea material. Asparagine polyurea material is a material with polyurea resin as the main component. The main components include isocyanate and polyamine resin. The two components react to form urea bonds through a step-by-step polymerization process to form asparagine polyurea. Asparagine polyurea is sprayed and solidified into a film with the characteristics of being dense, wear-resistant, acid-resistant, alkali-resistant, and temperature-resistant, thereby ensuring that its physical properties and durability can be maintained under long-term ultraviolet irradiation conditions, thereby extending the service life of the waterproof composite board 3.

[0060] Preferably, the dielectric layer 32 is made of epoxy-modified polyurethane material. Since the epoxy-modified polyurethane material contains epoxy groups and polyurethane bonds, it has good adhesion and flexibility, thereby achieving a close connection between the waterproof layer 33 and the base layer 31 .

[0061] Specifically, before spraying paint on the base layer 31, the surface of the base layer 31 needs to be polished and rust-free. However, attaching the waterproof layer 33 on the base layer 31 places extremely high requirements on the surface of the base layer 31. It is necessary to ensure that the surface of the base layer 31 is free of fingerprints, oil and polishing. It is not advisable to use polishing to meet the above requirements. Therefore, the surface of the base layer 31 is treated by using a coating medium layer 32, so that the surface of the base layer 31 meets the requirements, and at the same time, the bonding force is increased to make the waterproof layer 33 tightly connected to the base layer 31.

[0062] Furthermore, the thickness of the dielectric layer 32 is in the range of 0.03 mm to 0.05 mm. The appropriate thickness can prevent the thickness of the waterproof composite board 3 from being too large, thereby facilitating the transportation and installation of the waterproof composite board 3 .

[0063] Preferably, a protruding structure is formed on the base layer 31, which is generally formed by pressing, so as to meet the appearance requirements and installation needs.

[0064] Preferably, the board edges of the waterproof composite panels 3 are provided with connection parts for edge locking, and all the waterproof composite panels 3 are connected by edge locking, so that the construction of the house roof structure can be completed without other operations, thereby shortening the construction period of the house structure.

[0065] Specifically, the waterproof composite board 3 includes a main body 4, a first connecting part 5 and a second connecting part 6. The first connecting part 5 is located at the left end of the main body 4, and the second connecting part 6 is located at the right end of the main body 4. Any two adjacent waterproof composite boards 3 are respectively the first waterproof composite board and the second waterproof composite board. The first connecting part 5 of the first waterproof composite board and the second connecting part 6 of the second waterproof composite board overlap each other and are bent and buckled to form a locking edge structure 1.

[0066] Preferably, the locking structure 1 is a multiple curling structure. The first connection portion 5 of the first waterproof composite board and the second connection portion 6 of the second waterproof composite board are respectively curled to form a multiple curling structure, and all waterproof composite boards 3 are connected by the multiple curling structure, so that the construction of the house roof structure is completed without other operations, thereby shortening the construction period of the house structure.

[0067] like Figures 2 to 4 As shown, the specific embodiment of the present application further provides a roofing system 100, comprising a plurality of waterproof composite panels 3. Since the roofing system 100 adopts all embodiments of the waterproof composite panels 3, the roofing system 100 has all the beneficial effects brought by the waterproof composite panels 3.

[0068] In some embodiments, the connection parts of any two adjacent waterproof composite panels 3 are formed with a locking structure 1 for connecting with each other.

[0069] Specifically, the waterproof composite board 3 includes a main body 4, a first connecting part 5 and a second connecting part 6. The first connecting part 5 is located at the left end of the main body 4, and the second connecting part 6 is located at the right end of the main body 4. Any two adjacent waterproof composite boards 3 are respectively the first waterproof composite board and the second waterproof composite board. The first connecting part 5 of the first waterproof composite board and the second connecting part 6 of the second waterproof composite board overlap each other and are bent and buckled to form a locking edge structure 1.

[0070] Preferably, the locking structure 1 is a double curling structure. The first connection portion 5 of the first waterproof composite board and the second connection portion 6 of the second waterproof composite board are respectively curled to form a multiple curling structure, and all waterproof composite boards 3 are connected by the multiple curling structure, so that the construction of the house roof structure is completed without other operations, thereby shortening the construction period of the house structure.

The specific bending and curling construction process is as follows:

[0072] like Figure 5As shown, in the first step, the second connecting portion 6 is buckled with the first connecting portion 5, specifically, the right side of the second vertical section 62 is fitted with the left side of the first vertical section 51, and the upper side of the second horizontal section 61 is fitted with the lower side of the first horizontal section 52, and the second horizontal section 61 is located between the first vertical section 51 and the third vertical section 53;

[0073] like Figure 6 As shown, in the second step, the third vertical section 53 is bent rightward to form a first plug-in slot 7 with the first horizontal section 52 to be plugged and matched with the second horizontal section 61;

[0074] like Figure 7 As shown, in the third step, the second horizontal section 61, the first horizontal section 52 and the third vertical section 53 are bent downward so that the second horizontal section 61 and the second vertical section 62 form a second plugging groove 8 that is plugged and matched with the third vertical section 53;

[0075] The notch of the first plugging slot 7 faces upward, the notch of the second plugging slot 8 faces downward, and a bite seam is formed between the third vertical section 53 and the second vertical section 62 .

[0076] The double curling structure formed by the above bending and curling construction includes a first curling and a second curling, wherein the first curling includes a first layer curling 12, a third layer curling 14 and a fifth layer curling 16 that are curled from the outside to the inside and connected in sequence, a first transition section is connected between the first layer curling 12 and the third layer curling 14, and a third transition section is connected between the third layer curling 14 and the fifth layer curling 16; the second curling includes a second layer curling 13 and a fourth layer curling 15 that are curled from the outside to the inside and connected in sequence, and a second transition section is connected between the second layer curling 13 and the fourth layer curling 15; the third layer curling 14, the fifth layer curling 16 and the third transition section form a first plug-in groove 7 that is plug-matched with the fourth layer curling 15, the second layer curling 13, the fourth layer curling 15 and the second transition section form a second plug-in groove 8 that is plug-matched with the fifth layer curling 16, and a bite seam is formed between the fifth layer curling 16 and the second layer curling 13.

[0077] In fact, after the first step of the bending and curling construction, the first vertical section 51 forms the first layer of curling 12, and the second vertical section 62 forms the second layer of curling 13; after the second step of the bending and curling construction, the third vertical section 53 forms the fifth layer of curling 16 and the third transition section; after the third step of the bending and curling construction, the first horizontal section 52 forms the third layer of curling 14 and the first transition section, and the second horizontal section 61 forms the fourth layer of curling 15 and the second transition section.

[0078] Those skilled in the art will appreciate that the present application is not limited to the above-mentioned double curling structure, but may also be a triple curling structure, wherein the triple curling structure includes seven layers of curling arranged in a stacked manner, thereby achieving a tight connection of the waterproof composite board 3, and multiple curling structures including multiple layers of curling arranged in a stacked manner should all fall within the protection scope of the present application.

[0079] Preferably, the outward overlapping gap 2 of the locking structure 1, i.e., the bite seam of the multiple curling structure, is filled with a sealant 11, and the overlapping gap 2 is sealed by the sealant 11, so as to prevent excessive water accumulation on the roof structure of the house from entering the gap between the waterproof composite panels 3 through the overlapping gap, thereby enhancing the waterproofness of the roofing system 100.

[0080] Furthermore, the first connection portion 5 and the second connection portion 6 are both bent upward from the main body 4, and the sealing member 11 is also filled between the locking structure 1 and the main body 4 to cover the exposed portion of the second vertical section 62. In the rainy season, water on the roofing system 100 for a long time will corrode the waterproof layer 33 at the folded edge. The sealing member 11 is used to cover the roll waterproof layer 33 of the second vertical section 62, thereby extending the service life of the roofing system 100.

[0081] Those skilled in the art will appreciate that the seal 11 may be a structure in which a variety of sealing materials such as asphalt caulking paste, polyvinyl chloride joint paste and plastic paste, acrylic sealant, polyurethane sealant, polysulfide sealant and silicone sealant are used for filling, or a sealing strip or the like may be used to seal the overlap gap 2 and to be tightly connected to the rolled waterproof layer 33, and all structures shall fall within the scope of protection of the present application.

[0084] Furthermore, after adjacent waterproof composite panels 3 are connected, a trapezoidal mounting groove 10 is formed at the connection point, and the notch of the trapezoidal mounting groove 10 faces downward and is used to install the support frame 9. By setting the trapezoidal mounting groove 10 to install the support frame 9, the distance between the bottom surface of the waterproof composite panel 3 and the main structure of the house is reduced, thereby preventing the roof structure of the house from being blown away due to external force.

[0085] Specifically, the first edge segment 44 of one waterproof composite board 3 and the second edge segment 45 of the other waterproof composite board 3 are located in the same horizontal plane and serve as the bottom of the trapezoidal mounting groove 10; the first inclined segment 42 of one waterproof composite board 3 and the second inclined segment 43 of the other waterproof composite board 3 serve as the groove wall of the trapezoidal mounting groove 10; the top of the support frame 9 extends from between the first edge segment 44 and the second edge segment 45 into the multiple curling structure for limited engagement, and the bottom of the support frame 9 is fixedly connected to the main structure of the house.

[0086] Preferably, the support frame 9 includes a support portion 92 and a hanging ear portion 91 arranged at the upper end of the support portion 92, the hanging ear portion 91 is limitedly matched with the locking structure 1, the top surface of the main structure of the house has multiple purlins 200, and the lower end of the support frame 9 is connected to the purlin 200.

The waterproof composite panel 3 includes a base layer 31 and a roll waterproof layer 33 covering the base layer 31. By laying the waterproof composite panel 3, the main structure of the roof and the waterproof structure of the roof are constructed simultaneously, thereby shortening the construction period of the house roofing structure.
