Description

Technical Field

[0001] The utility model relates to the technical field of industrial plant construction, in particular to an integrated photovoltaic roof panel with 360-degree vertical locking edges. Background Art

[0002] In industrial plants, steel frames or truss structures are often used, and the top roof is often used to install photovoltaic panels to generate electricity using solar energy.

[0003] According to traditional construction technology, the roof has the following structures from bottom to top: base plate layer, vapor barrier layer, thermal insulation layer, waterproof layer, panel layer, photovoltaic layer. Secondary purlins need to be installed between the base plate layer and the panel layer, and the structure is heavy. Each layer of structure and secondary purlin are constructed in sequence, with a total of 7 processes. The construction period is long, and it takes a lot of manpower and material resources. It is easy to form cold bridges. In addition, the photovoltaic layer is usually constructed by the power department, while the other processes are constructed by the construction department. The construction management is difficult and there is a risk of mismatch. After the photovoltaic layer is constructed, it is the pure load of the roof, which increases the burden on the roof structure.

[0004] In addition, the photovoltaic roof structure of the prior art usually requires 7 steps of on-site construction, which requires a high level of technical skills of the construction personnel and is difficult to inspect after construction. During on-site construction, the top plate layer is located above the insulation layer and the waterproof layer, and it is necessary to nail the top plate layer, which will damage the waterproof layer below and affect the waterproof performance of the roof. Therefore, it is necessary to provide an integrated photovoltaic roof panel with 360° vertical locking edge, which can solve the problems of multiple photovoltaic roof construction steps, long construction period, difficulty in construction management by different departments, and poor roof waterproof performance in the prior art. Summary of the invention

[0005] The purpose of the utility model is to provide an integrated photovoltaic roof panel with 360° upright locking edge, which can solve the problems in the prior art of photovoltaic roof construction with multiple construction processes, long construction period, difficult construction management by different departments, and poor roof waterproofing performance.

[0006] The utility model is achieved in this way:

[0007] An integrated photovoltaic roof panel with 360° vertical locking edge comprises a bottom panel, a thermal insulation layer, a waterproof layer, a panel layer, a photovoltaic layer and electromagnetic induction nails; the bottom panel, the thermal insulation layer, the waterproof layer, the panel layer and the photovoltaic layer are arranged in sequence from bottom to top to form an integrated photovoltaic roof panel; a plurality of electromagnetic induction nails are pre-buried in the thermal insulation layer, and a plurality of electromagnetic induction nails are screwed downward into the main purlin, so that the integrated photovoltaic roof panel is installed on the main purlin of the roof; the bottom of one end of the integrated photovoltaic roof panel extends outward to form a first extension part, and the top of the other end of the integrated photovoltaic roof panel extends outward to form a second extension part, so that two adjacent integrated photovoltaic roof panels are spliced ​​through the first extension part and the second extension part.

[0008] One end of the bottom plate along the length direction is flush with one end of the insulation layer along the length direction, and the other end of the bottom plate along the length direction extends to the outside of the other end of the insulation layer along the length direction to form a first extension portion; when two adjacent integrated photovoltaic roof panels are spliced, the bottom surface of the other end of one integrated photovoltaic roof panel overlaps the first extension portion of one end of the other integrated photovoltaic roof panel.

[0009] The two ends of the bottom plate along the width direction are respectively flush with the two ends of the insulation layer along the width direction.

[0010] The other end of the panel layer along the length direction extends to the outside of one end of the insulation layer along the length direction to form a second extension portion; when two adjacent integrated photovoltaic roof panels are spliced, the second extension portion at the other end of one integrated photovoltaic roof panel is overlapped on the panel layer at one end of the other integrated photovoltaic roof panel.

[0011] The two ends of the panel layer along the width direction are flush with the two ends of the insulation layer along the width direction, and the two ends of the panel layer along the length direction respectively extend out of the two ends of the photovoltaic layer along the length direction.

[0012] The photovoltaic layer includes a photovoltaic protection bracket and a photovoltaic unit panel; the photovoltaic protection bracket is a grid-like structure and is arranged between the top surface of the panel layer and the two side surfaces of the waterproof layer, and a plurality of photovoltaic unit panels are respectively embedded in a plurality of grids of the photovoltaic protection bracket.

[0013] The top surface of the photovoltaic protection bracket is higher than the top surface of the photovoltaic unit panel, so that the photovoltaic unit panel is sunken and embedded in the grid of the photovoltaic protection bracket; the height of the photovoltaic protection bracket is less than the height of the upper rolls on both sides of the waterproof layer.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model forms an integrated photovoltaic roof panel in the factory by processing the bottom plate, the insulation layer of the pre-embedded electromagnetic induction nails, the waterproof layer, the panel layer and the photovoltaic layer in a standardized manner. During on-site construction, only one hoisting is required. Through the fixation of the electromagnetic induction nails to the main purlin and the overlap fixation of the first extension part and the second extension part, a photovoltaic roof structure with a stable structure can be formed, which reduces on-site construction procedures and construction departments, is conducive to efficient construction and construction management, has low requirements on the technical level of construction personnel, and at the same time avoids the damage of the waterproof layer by nailing, thereby ensuring the waterproof and anti-seepage performance of the roof.

[0016] 2. The utility model is provided with a photovoltaic protection bracket and a photovoltaic unit panel. The photovoltaic unit panel is installed in the grille of the photovoltaic protection bracket in a sunken embedded manner. When the photovoltaic roof is stepped on, the photovoltaic protection bracket bears the force and will not cause damage or destruction to the photovoltaic unit panel, thereby meeting the construction walking requirements of other roof processes.

[0017] 3. The utility model is provided with a photovoltaic layer, and the photovoltaic layer is directly formed on the integrated photovoltaic roof panel, thereby avoiding the problem of increasing the pure load of the roof structure by installing the photovoltaic layer later in the prior art. At the same time, the photovoltaic protection bracket can be used to bear the load, so there is no need to construct a secondary purlin between the bottom plate and the panel layer, which reduces the consumption of steel and the weight of the roof structure, which is conducive to avoiding the formation of cold bridges.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Please see attached Figure 1 and attached Figure 2 , an integrated photovoltaic roof panel with 360° upright locking, comprising a bottom panel 1, an insulation layer 2, a waterproof layer 3, a panel layer 4, a photovoltaic layer and electromagnetic induction nails; the bottom panel 1, the insulation layer 2, the waterproof layer 3, the panel layer 4 and the photovoltaic layer are arranged in sequence from bottom to top to form an integrated photovoltaic roof panel; a plurality of electromagnetic induction nails (not shown in the figure) are pre-buried in the insulation layer 2, and a plurality of electromagnetic induction nails are screwed downward into the main purlin, so that the integrated photovoltaic roof panel is installed on the main purlin of the roof; the bottom of one end of the integrated photovoltaic roof panel extends outward to form a first extension part 8, and the top of the other end of the integrated photovoltaic roof panel extends outward to form a second extension part 9, so that two adjacent integrated photovoltaic roof panels are spliced ​​through the first extension part 8 and the second extension part 9.

[0023] The bottom plate 1, the insulation layer 2, the waterproof layer 3, the panel layer 4 and the photovoltaic layer are arranged in sequence from bottom to top, and electromagnetic induction nails are embedded in the insulation layer 2 to form an integrated photovoltaic roof panel. The waterproof layer 3 forms a U-shaped structure with both sides rolled up according to the 360° vertical locking process requirements. According to the design and layout requirements of the roof panel, the integrated photovoltaic roof panel is directly manufactured in the factory. Due to the use of an integrated structure, the single-layer stress considered in traditional construction is converted into the integrated joint stress of the utility model, which can maximize the use of the strength of the material, save the use of materials while ensuring the load capacity, and avoid the problems of incompatibility of products from different manufacturers such as steel materials and photovoltaic components.

[0024] During on-site construction, the integrated photovoltaic roof panels are directly hoisted onto the roof structure and fixed to the main purlin by electromagnetic induction nails. Adjacent integrated photovoltaic roof panels are overlapped by the first extension part 8 and the second extension part 9 to form an overall roof panel structure. There is no need to construct secondary purlins, the construction process is simple, and sequential or cross-construction by construction personnel from different departments is avoided, thus shortening the construction period.

[0025] Please see attached Figure 1 One end of the bottom plate 1 along the length direction is flush with one end of the insulation layer 2 along the length direction, and the other end of the bottom plate 1 along the length direction extends to the outside of the other end of the insulation layer 2 along the length direction to form a first extension portion 8; when two adjacent integrated photovoltaic roof panels are spliced, the bottom surface of the other end of one integrated photovoltaic roof panel is overlapped on the first extension portion 8 of one end of the other integrated photovoltaic roof panel.

[0026] The first extension portion 8 is formed by extending outwardly through the end of the bottom panel 1, which facilitates the connection of two adjacent integrated photovoltaic roof panels in the length direction. The bottom connection reliability of the two adjacent integrated photovoltaic roof panels in the length direction is effectively improved by overlapping the bottom panel 1 through the first extension portion 8.

[0027] Please see attached Figure 1 The two ends of the bottom plate 1 along the width direction are flush with the two ends of the insulation layer 2 along the width direction, ensuring that the integrated photovoltaic roof panel is spliced ​​flat along the width direction.

[0028] Please see attached Figure 1 The other end of the insulation layer 2 along the length direction is flush with one end of the panel layer 4 along the length direction, and the other end of the panel layer 4 along the length direction extends to the outside of one end of the insulation layer 2 along the length direction to form a second extension portion 9; when two adjacent integrated photovoltaic roof panels are spliced, the second extension portion 9 at the other end of one integrated photovoltaic roof panel is overlapped on the panel layer 4 at one end of the other integrated photovoltaic roof panel.

[0029] The second extension portion 9 is formed by extending outwardly through the end of the panel layer 4, which facilitates the connection of two adjacent integrated photovoltaic roof panels in the length direction. The overlap of the panel layer 4 through the second extension portion 9 effectively improves the reliability of the top connection of the two adjacent integrated photovoltaic roof panels in the length direction, thereby ensuring the reliable splicing of the two adjacent integrated photovoltaic roof panels in the length direction through the first extension portion 8 and the second extension portion 9.

[0030] Please see attached Figure 1 The two ends of the panel layer 4 along the width direction are flush with the two ends of the insulation layer 2 along the width direction, and the two ends of the panel layer 4 along the length direction respectively extend out of the two ends of the photovoltaic layer along the length direction, ensuring that the integrated photovoltaic roof panel is spliced ​​flat along the width direction.

[0031] The waterproof layer 3 is completely wrapped around the bottom and both side surfaces of the panel layer 4 to form a 360° vertical locking structure. After the integrated photovoltaic roof panels are flatly spliced ​​along the width direction, 360° vertical locking is used to ensure the splicing reliability of the integrated photovoltaic roof panels along the width direction.

[0032] The photovoltaic layer is shorter than the panel layer 4 , and can be avoided by the indented photovoltaic layer when the second extension portion 9 overlaps the panel layer 4 .

[0033] Please see attached Figure 1 The photovoltaic layer includes a photovoltaic protection bracket 5 and a photovoltaic unit panel 6; the photovoltaic protection bracket 5 is a grid-like structure and is arranged between the top surface of the panel layer 4 and the two side surfaces of the waterproof layer 3, and a plurality of photovoltaic unit panels 6 are respectively embedded in a plurality of grids of the photovoltaic protection bracket 5.

[0034] After the photovoltaic roof construction is completed, other processes of the roof structure need to be carried out. It is inevitable to step on the photovoltaic roof during construction, which can easily damage the photovoltaic panels. In the present utility model, the photovoltaic unit panels 6 are embedded and protected by the grid-shaped photovoltaic protection bracket 5, which reduces the damage caused by stepping on the photovoltaic unit panels 6. The grid-shaped photovoltaic protection bracket 5 has a strong load-bearing capacity and can meet the normal walking needs of construction workers.

[0035] Since the photovoltaic protection bracket 5 is subjected to force, the strength of the corrugated steel plate of the bottom plate 1 can be appropriately reduced, and there is no need to install a secondary purlin, which reduces the consumption of steel and the deadweight of the overall roof structure, which is beneficial to preventing the formation of cold bridges.

[0036] Please see attached Figure 1 The top surface of the photovoltaic protection bracket 5 is slightly higher than the top surface of the photovoltaic unit panel 6, so that the photovoltaic unit panel 6 is sunken and embedded in the grid of the photovoltaic protection bracket 5; the height of the photovoltaic protection bracket 5 is less than the upper roll height of the waterproof layer 3 on both sides.

[0037] The photovoltaic unit panel 6 is embedded in a sunken manner to ensure that the photovoltaic unit panel 6 will not be damaged by being stepped on. The top surface of the photovoltaic protection bracket 5 is lower than the top of the waterproof layer 3 to ensure that the 360° vertical locking edge construction technology is carried out in the width direction of the waterproof layer 3.

[0038] Please see attached Figure 1 and attached Figure 2 , the production and installation method of the utility model is:

[0039] The bottom plate 1 is made of galvanized aluminum corrugated steel sheet. The length of the galvanized aluminum corrugated steel sheet is selected according to the design requirements and matches the spacing of the main purlins, so as to facilitate the fixing of the integrated photovoltaic roof panel to the main purlin of the roof structure through electromagnetic induction nails. The width of the galvanized aluminum corrugated steel sheet is determined according to the width of the plate, and the color of the galvanized aluminum corrugated steel sheet is determined according to the use requirements. The top surface of the galvanized aluminum corrugated steel sheet is not painted, which is convenient for the bonding and fixing of the thermal insulation layer 2.

[0040] The insulation layer 2 can be made of high-strength rock wool layer, the bulk density of which is determined according to the design requirements, preferably not less than 180kg / m 3 The high-strength rock wool layer is fixed to the bottom plate 1 by gluing to form an integrated structure, and when gluing, an overlap length, i.e., the first extension portion 8, is left at one end of the bottom plate 1, and the overlap length can be adaptively set according to actual overlap requirements.

[0041] The panel layer 4 can be made of aluminum-zinc-plated corrugated steel sheet, and the waterproof layer 3 is a polymer waterproof coiled material, preferably, a 1.5 mm thick H-type TPO coiled material can be used. The length of the waterproof layer 3 is consistent with the length of the panel layer 4. After the two ends of the waterproof layer 3 in the width direction are rolled up, a 360° locking length is reserved to meet the 360° vertical locking construction requirements. The 360° vertical locking construction is a conventional roof construction process in this field, which will not be repeated here.

[0042] The waterproof layer 3 is fixed to the thermal insulation layer 2 and the panel layer 4 by gluing. When the panel layer 4 is installed, it extends an overlap length in the opposite direction of the first extension portion 8, namely the second extension portion 9. The overlap length can be adaptively set according to the actual overlap requirements. The bottom plate 1, the thermal insulation layer 2, the waterproof layer 3 and the panel layer 4 are aligned at both ends in the width direction.

[0043] The photovoltaic protection bracket 5 is made of 3mm thick glass fiber reinforced plastic in a grid shape. The size of the grid can be smaller than the size of an adult's foot. Therefore, after the photovoltaic unit panel 6 is sunken and embedded in the photovoltaic protection bracket 5, the construction personnel will not damage the photovoltaic unit panel 6 when stepping on the photovoltaic roof. Preferably, the top surface of the photovoltaic unit panel 6 is sunken about 10mm below the top surface of the photovoltaic protection bracket 5. After being manufactured in the factory, the photovoltaic unit panel 6 is directly embedded in the photovoltaic protection bracket 5 and fixed by gluing. The photovoltaic protection bracket 5 is directly glued to the panel layer 4, thereby avoiding cross-construction by different departments on site and reducing management difficulty.

[0044] During on-site installation, the integrated photovoltaic roof panel consisting of the bottom plate 1, the insulation layer 2, the waterproof layer 3, the panel layer 4 and the photovoltaic layer is directly hoisted onto the main purlin, and the electromagnetic induction nails are rotated and driven into the main purlin by special tools, thereby fixing the integrated photovoltaic roof panel on the roof structure.

[0045] Along the length direction of the integrated photovoltaic roof panel, the bottom surface of the other end of an integrated photovoltaic roof panel overlaps the first extension 8 of one end of another integrated photovoltaic roof panel, and the overlapping parts of the bottom panels 1 of two adjacent integrated photovoltaic roof panels are connected and fixed by conventional processes such as screw connection. The bottom surface of the second extension 9 of the other end of an integrated photovoltaic roof panel (i.e., the bottom surface of the waterproof layer 3) overlaps the top surface of the panel layer 4 of one end of another integrated photovoltaic roof panel, and the overlapping parts of the waterproof layer 3 and the panel layer 4 of two adjacent integrated photovoltaic roof panels are connected and fixed by conventional processes such as gluing. Along the width direction of the integrated photovoltaic roof panel, it is connected by 360° vertical locking method.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
