[0045] According to data released by the National Energy Administration, by the end of 2024, the cumulative installed capacity of distributed photovoltaic power generation will reach 370 million kilowatts, 121 times that of the end of 2013, accounting for 42% of all photovoltaic power generation installed capacity. In terms of new installed capacity, the new installed capacity of distributed photovoltaic power generation in 2024 will reach 120 million kilowatts, accounting for 43% of the new installed capacity of photovoltaic power generation that year. Distributed photovoltaic power generation has become an important force in energy transformation.

[0046] Distributed photovoltaic power stations are usually built on the roofs of factory buildings. The factory roofs that were originally underutilized by the enterprise can be effectively utilized, thereby improving industrial efficiency and creating new economic value. However, the factory building has extremely high requirements for waterproofing, and leakage will affect the normal production of the enterprise. At present, the high-quality buildings that can be built with rooftop photovoltaics have basically been completed, and the resources that can be developed are becoming less and less. Buildings that have not been built with rooftop photovoltaics have been built for a long time and have poor load-bearing capacity.

[0047] The inventors have found that when building distributed photovoltaics on non-color steel tile roofs, the columns are usually set directly on the waterproof layer of the roof. However, for roofs that are old, if this method is used, the photovoltaic panels cannot be installed normally due to the poor bearing capacity of the roof.

[0048] The present invention proposes a structure for restoring roof insulation, aiming to solve the technical problem that the load bearing capacity and waterproof capacity of the existing roof, which have been in use for a long time, cannot meet the requirements for installing photovoltaic panels.

[0049] See also Figure 1 In one embodiment of the present invention, the structure 100 for restoring roof insulation is used to be arranged on a roof 200, the roof 200 includes a structural plate 210, an insulation layer 220 and a waterproof layer 230, the insulation layer 220 is laid on the structural plate 210, the waterproof layer 230 is laid on the insulation layer 220, the structure 100 for restoring roof insulation includes a column 1, a composite filling layer 2, a waterproof roll 3 and a sealing paste component 4, the column 1 includes a column body 11 and a structural adhesive layer 12, one end of the column body 11 is connected to the structural adhesive layer 12, the roof 200 is provided with a through hole penetrating the waterproof layer 230 and the insulation layer 220, and the structural adhesive layer 12 is connected to the structural plate 210 through the through hole; the composite filling layer 220 is laid on the structural plate 210, and the waterproof layer 230 is laid on the insulation layer 220. The filling layer 2 is filled in the through hole, and the bottom surface of the filling layer is connected to the structural plate 210 and the column 1; the waterproof membrane 3 includes a folding portion and a flat portion arranged around the periphery of the folding portion, the folding portion is arranged in contact with the column body 11 on one side facing the column body 11, the folding portion is arranged around the periphery of the column body 11, and the flat portion is laid on the top surface of the waterproof layer 230; the sealing paste assembly 4 includes a first sealing member 41 and a second sealing member 42, the first sealing member 41 is respectively sealed and connected to the folding portion and the column body 11, and is used to seal the gap between the folding portion and the column body 11; the second sealing member 42 is respectively sealed and connected to the flat portion and the waterproof layer 230, and is used to seal the gap between the flat portion and the waterproof layer 230.

[0050] The technical solution of the present invention is to open through holes in the waterproof layer 230 and the thermal insulation layer 220 so that a part of the structural plate 210 is exposed through the through holes, and then the column body 11 is directly connected to the exposed structural plate 210 through the structural adhesive layer 12, so that the weight and related loads of the photovoltaic panel can be directly transferred to the structural plate 210 through the column 1 without passing through other intermediate components. This transmission method reduces the deformation and internal force accumulation of the intermediate links, thereby reducing the load effect of the overall structure, that is, reducing the load, thereby meeting the load requirement that the roof 200 can withstand; the through holes are then filled with a composite filling layer 2, and after the filling is completed, the waterproof membrane 3 is laid to improve the waterproof performance, wherein the waterproof membrane 3 includes a folding portion and a ring-shaped The flat part on the periphery of the folding part is formed by bending upward compared to the flat part. The folding part surrounds the column body 11, and the bottom of the folding part is connected to the flat part. The flat part is laid on the waterproof layer 230, so that water is not easy to enter the composite filling layer 2, and it is not easy to contact the structural plate 210, thereby improving the waterproof performance. Then, the first seal 41 is used to seal the gap between the folding part and the column body 11 to prevent water from entering the gap between the folding part and the column body 11 and contacting the composite filling layer 2, thereby improving the waterproof performance; the second seal 42 is used to seal the gap between the flat part and the waterproof layer 230 to prevent water from entering the composite filling layer 2 from the gap between the flat part and the waterproof layer 230, further improving the waterproof performance. It should be noted that the photovoltaic panel can be directly connected to the column 1, or it can be connected to the column 1 through a bracket. The composite filling layer 2 can be composed of one material or multiple materials, which is not limited here. The first sealing member 41 and the second sealing member 42 may be sealed by grease or by sealing paste, which is not limited here.

[0051] See also Figure 1 In one embodiment, the composite filling layer 2 includes a first filling layer 21 and a second filling layer 22. The first filling layer 21 is located in the through hole. The first filling layer 21 includes a connecting surface and a leveling surface arranged opposite to each other along a first direction. The connecting surface is connected to the structural plate 210 and the column 1, and the leveling surface is parallel to the top surface of the structural plate 210. The second filling layer 22 is located in the through hole, the bottom surface of the second filling layer 22 is in contact with the leveling surface, and the top surface of the second filling layer 22 is flush with the waterproof layer 230. The through hole is filled by setting the first filling layer 21 and the second filling layer 22, and the first filling layer 21 is used for leveling, and the through hole is filled by the second filling layer 22 to ensure the filling quality.

[0052] In one embodiment, the first filling layer 21 includes a mortar layer, and the second filling layer 22 includes an asphalt paste layer. The mortar layer is formed by leveling with DS-M15 mortar (1:3 cement mortar), where DS refers to: dry-mixed ground, floor, roof plastering mortar, leveling mortar; M15 is the strength grade of the cement mortar surface layer. The second filling layer 22 is formed with asphalt paste to ensure the filling quality of the through hole.

The second roll material layer 32 includes a second folded portion 321 folded upward and a second flat portion 322 arranged around the periphery of the second folded portion 321. The first folded portion 311 and the second folded portion 321 form a folded portion, and the first flat portion 312 and the second flat portion 322 form a flat portion. One side of the first folded portion 311 is in contact with the outer wall of the column body 11. The other side of the first folded portion 311 is in contact with the second folded portion 321, one side of the first flat portion 312 is in contact with the waterproof layer 230, and the other side of the first flat portion 312 is in contact with the second flat portion 322. The first sealing member 41 is connected to the second folded portion 321 and the side wall of the column body 11 to seal the gap between the first end of the second folded portion 321 away from the second flat portion 322 and the side wall of the column body 11; the second sealing member 42 is connected to the outer edge of the second flat portion 322 and the waterproof layer 230 to seal the gap between the outer edge of the second flat portion 322 and the waterproof layer 230. By providing the first coiled material layer 31 and the second coiled material layer 32 for waterproofing, compared with a single coiled material layer, the waterproofing performance is undoubtedly better and the reliability is higher. One side of the first folded portion 311 is fitted with the outer wall of the column body 11, reducing the probability of water entering the composite filling layer 2 from the gap between the first folded portion 311 and the side wall of the column body 11, thereby improving the waterproof performance; the other side of the first folded portion 311 is fitted with the second folded portion 321, reducing the probability of water entering the first roll material layer 31 and the second roll material layer 32 from the gap between the first folded portion 311 and the second folded portion 321; and then the first sealing member 41 is connected to the second folded portion 321 and the side wall of the column body 11, thereby sealing the gap between the first end of the second folded portion 321 away from the second flat portion 322 and the side wall of the column body 11. Since the second folded portion 321 is located on the outside, the first sealing member 41 is sealed and connected to the second folded portion 321. When the first folded portion 311 and the column body 11 are sealed, the gap between the first folded portion 311 and the column body 11 is also sealed, thereby preventing water from entering the composite filling layer 2 from the gap between the first folded portion 311 and the column body 11, thereby improving the waterproof performance; the second sealing member 42 is connected to the second flat portion 322, thereby preventing water from entering the composite filling layer 2 from the gap between the second flat portion 322 and the waterproof layer 230; similarly, since the second flat layer is located on the outside of the first flat layer, when the second flat layer is sealed and connected to the second sealing member 42, the second sealing member 42 will also seal the gap between the first flat layer and the waterproof layer 230, thereby preventing water from entering the composite filling layer 2 from the gap between the first flat layer and the waterproof layer 230, thereby improving the waterproof performance. It should be noted that the first roll material layer 31 and the second roll material layer 32 can be a 3mm thick self-adhesive polymer modified asphalt waterproof roll material 3.

The folding height of the second folded portion 321 is higher than the folding height of the first folded portion 311, so that the second folded portion 321 can press the outer edge of the first folded portion 311 to form a first waterproof layer, and the pressed first folded portion 311 forms a second waterproof layer; the length of the second flat portion 322 is greater than the length of the first flat portion 312, so that the second flat portion 322 can press the outer edge of the first flat portion 312 to form a first waterproof layer, and the pressed first flat portion 312 forms a second waterproof layer. The height of the folded portion 321 is higher than the first folded portion 311, and the length of the second flat portion 322 is greater than the first flat portion 312, so that the second roll material layer 32 completely covers the first roll material layer 31. The second roll material layer 32, the column body 11, the waterproof layer 230, the first seal 41, and the second seal 42 form a first waterproof layer, and together enclose a storage space 5. The first roll material layer 31 located in the storage space 5 forms a second waterproof layer with the column body 11 and the waterproof layer 230, thereby effectively improving the waterproof performance.
