Technical Field
[0001] The utility model belongs to the technical field of building integrated photovoltaics, and specifically relates to a building integrated photovoltaics roof structure. Background Art
[0002] With the development of society, people pay more and more attention to the development and utilization of new energy. As one of the most direct new energies, solar energy has always been highly regarded. Nowadays, BIPV is one of the innovations in photovoltaic solar technology. BIPV technology is a technology that integrates solar power generation (photovoltaic) products into buildings. As the roof surface, photovoltaic panels can not only block external light, wind, rain, and particulate debris, but also provide clean electric energy for building users, belonging to an environmentally friendly building form.
[0003] At present, the conventional BIPV photovoltaic system is to build a bracket system for fixing photovoltaic panels on the original color steel tile roof. The bracket system includes accessories such as water guide grooves, brackets, structural supports, and ridge components. Due to the large number of accessories, the combination of each accessory will consume a lot of time and manpower, affecting the assembly efficiency; secondly, the above accessories will increase the load borne by the roof itself after being installed on the color steel tile roof, resulting in affecting the service life and safety of the color steel tile roof itself.
[0004] In view of this, a building integrated photovoltaics roof structure is proposed. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a building integrated photovoltaics roof structure to solve the above-mentioned problems.
[0006] The technical solution adopted by the utility model is as follows: A building integrated photovoltaics roof structure includes a substrate, side pressing blocks, and middle pressing blocks. The substrate is convex upward at equal intervals in the horizontal direction to form a plurality of upper peak parts, and hook positions are formed by bending both sides of the upper peak parts; both the side pressing blocks and the middle pressing blocks include pressing block parts, bolts, and hook parts pre-assembled into one body in the factory. Hook grooves adapted to slide guidingly on the hook positions are provided on the opposite sides of the hook parts, and both the side pressing blocks and the middle pressing blocks are locked on the upper peak parts through bolts.
[0007] In a preferred embodiment, both the side pressing blocks and the middle pressing blocks are multiple, and are arranged horizontally and vertically on the substrate. An installation space for fixing photovoltaic panels is formed by enclosing between the side pressing blocks, the middle pressing blocks, and the substrate.
[0008] In a preferred embodiment, both sides of the pressing block part in the middle pressing block have upper fixing wing edges extending outward integrally. One side of the pressing block part in the side pressing block has an upper fixing wing edge extending outward integrally, and the other side of the pressing block part in the side pressing block also has a lower fixing wing edge fitting on the upper surface of the upper peak part.
[0009] In a preferred embodiment, anti-slip patterns are provided on the bottom surfaces of both the upper fixed wing edge and the lower fixed wing edge, and an L-shaped groove for defining the side surface of the photovoltaic panel is formed by enclosing between the upper fixed wing edge and the pressing block member.
[0010] In a preferred embodiment, holes for the bolts to pass through are vertically formed at the centers of the pressing block member and the hook member. A blocking surface protrudes from the opposite sides of the hook member, and a slot for placing nuts is formed by enclosing between the hook member and the blocking surface. The bolt passes through the hole and is threadedly connected to the nut, and the bottom surface of the blocking surface is attached to the upper end surface of the upper peak portion.
[0011] In a preferred embodiment, the substrate is formed by splicing multiple color-coated steel tiles, and the color-coated steel tiles are connected together by 360° standing seam locking.
[0012] In a preferred embodiment, the substrate further has alternately arranged peak positions and valley positions.
[0013] In a preferred embodiment, the color-coated steel tiles in the substrate are made of galvanized aluminum-magnesium plates.
[0014] In a preferred embodiment, both the pressing block member and the hook member are formed by extrusion of aluminum alloy materials.
[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:
[0016] 1. In the present utility model, an upper peak portion capable of additionally increasing the load capacity is designed on the color-coated steel tile roof.

The upper peak portion, the side pressing block and the middle pressing block form a strip-shaped support structure with stronger load capacity. While ensuring the trampling property of the component, there is no need to reserve an operation and maintenance passage. On the premise of the same area, the installed capacity can be increased by 15%, and the roof utilization rate is higher.
[0017] 2. In the present utility model, the photovoltaic panel can be tightly pressed on the substrate through the cooperation of the upper peak portion, the side pressing block and the middle pressing block to realize the overall combination operation, and the bracket used in the traditional BIPV is abandoned.

Specific embodiments
[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0027] Refer to Figures 1-7 , the photovoltaic building integrated roofing structure includes a substrate 2, a side pressing block 3 and a middle pressing block 1. The substrate 2 is formed with a plurality of upper peak portions 21 protruding upward at equal intervals in the transverse direction, and hook positions 211 are formed by bending both sides of the upper peak portion 21; both the side pressing block 3 and the middle pressing block 1 include a pressing block member 12, a bolt 13 and a hook member 11 pre-assembled into one body in the factory. The side pressing block 3 and the middle pressing block 1 are integrally pre-installed type, and the pressing block member 12, the bolt 13 and the hook member 11 have been assembled in a supporting manner before leaving the factory, and construction workers do not need to assemble them separately, so that the overall installation operation is convenient and the system installation efficiency can be improved.
[0028] Furthermore, a hook groove 111 adapted to slide guidingly on the hook position 211 is provided on the opposite side of the hook member 11. The edge pressing block 3 and the middle pressing block 1 are both locked to the upper peak portion 21 by bolts 13. An upper peak portion 21 capable of additionally increasing the load capacity is designed on the color steel tile roof. When installing a photovoltaic panel (not shown in the figure), it is only necessary to correspondingly install the edge pressing block 3 and the middle pressing block 1 on the upper peak portion 21. The upper peak portion 21, the edge pressing block 3 and the middle pressing block 1 form a strip-shaped support structure with stronger load capacity. While ensuring the trampling resistance of the components, there is no need to reserve an operation and maintenance passage. On the premise of the same area, the installed capacity can be increased by 15%, and the roof utilization rate is higher.
[0029] Furthermore, both the edge pressing block 3 and the middle pressing block 1 are multiple, and are arranged horizontally and vertically on the substrate 2. An installation space for fixing the photovoltaic panel is formed by enclosing between the edge pressing block 3, the middle pressing block 1 and the substrate 2. Through the cooperation of the upper peak portion 21, the edge pressing block 3 and the middle pressing block 1, the photovoltaic panel can be tightly pressed on the substrate 2 to realize the overall combination operation, abandoning the brackets used in traditional BIPV. The above-designed installation method can greatly save the materials required, improve the assembly efficiency (simple and convenient, saving more than 60% of the installation time), while reducing the cost and the load borne by the roof, and ensuring the service life of the subsequent integrated photovoltaic building.
[0030] Furthermore, on both sides of the pressing block member 12 in the middle pressing block 1, there are upper fixing wing edges 121 integrally extending outwards. On one side of the pressing block member 12 in the edge pressing block 3, there is an upper fixing wing edge 121 integrally extending outwards. On the other side of the pressing block member 12 in the edge pressing block 3, there is also a lower fixing wing edge fitting on the upper surface of the upper peak portion 21. An L-shaped groove for limiting on the side of the photovoltaic panel is formed by enclosing between the upper fixing wing edge 121 and the pressing block member 12. A hole position 122 for the bolt 13 to pass through is vertically opened at the center of the pressing block member 12 and the hook member 11. A stop surface 113 protrudes on the opposite side of the hook member 11. A groove position 12 for placing a nut is formed by enclosing between the hook member 11 and the stop surface 113. The bolt 13 passes through the hole position 122 and is threadedly connected with the nut. The bottom surface of the stop surface 113 is in contact with the upper end surface of the upper peak portion 21. When fixing the photovoltaic panel on site, first install the edge pressing block 3 and the middle pressing block 1 correspondingly at the upper peak portion 21. At this time, tighten the bolt 13. During the tightening process, the upper fixing wing edge 121 presses downwards, and the fixing of the photovoltaic panel can be completed. The additional lower fixing wing edge can also ensure the strength after the photovoltaic panel is fixed.
[0031] Among them, the edge pressing block 3 is the fixing part between the outermost photovoltaic panel and the substrate 1, and the middle pressing block 1 is the fixing part between two photovoltaic panels.
[0032] Furthermore, anti-slip patterns are provided on the bottom surfaces of both the upper fixed wing edge 121 and the lower fixed wing edge. The designed anti-slip patterns can increase the friction between the upper fixed wing edge 121 and the lower fixed wing edge when pressing down on the photovoltaic panel and the substrate 2, thereby improving the overall fixing effect.
[0033] Furthermore, the substrate 2 is formed by splicing multiple color steel tiles, and the two color steel tiles are connected together by 360° standing seam locking 22. Using 360° standing seam locking 22 as the connecting part of the color steel tiles can endow the substrate 2 with stronger gripping force, ensure the integrity of the roof seams of the BIPV under strong wind conditions, and effectively extend the service life of the system.
[0034] Furthermore, the substrate 2 also has alternately arranged peak positions and valley positions, and the peak positions and valley positions can be used as stiffening rib positions and also as rain gutters.
[0035] Furthermore, the color steel tiles in the substrate 2 are made of galvanized aluminum-magnesium plates. The roof integrated tiles made of galvanized aluminum-magnesium plates have the advantages of low cost, rust prevention, corrosion resistance, environmental protection, and long service life.
[0036] Furthermore, both the pressing block 12 and the hook 11 are formed by extrusion of aluminum alloy materials. The pressing block 12 is made of aluminum alloy materials, with strong corrosion resistance and good strength. While ensuring the overall service life, the cost is relatively low, and the production efficiency is higher due to the use of extrusion molding.
[0037] Among them, the bolts 13 and nuts are preferably made of stainless steel materials, which are not limited herein. The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
