Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic buildings, and in particular to a building photovoltaic integrated product and an installation method. Background Art

[0002] Whether it is the roof or the wall, they all belong to the building's external protective structure. With the development of the building intelligent manufacturing industry, the building's enclosure materials, insulation materials, decorative functions and solar photovoltaic power generation components and other functional material systems are integrated into integrated parts in the factory to form a building photovoltaic integrated system, namely "BIPV": a solar photovoltaic power generation system that is designed, constructed and installed at the same time as the building and forms a perfect combination with the building can be called a "building material type" solar photovoltaic building. As part of the building's external structure, it has both the power generation function and the functions of building components and building materials. It can even enhance the building's beauty, forming a perfect unity with the building, and can "form a wall in one sequence."

[0003] At present, there are many problems in the application of photovoltaic buildings in my country. On the one hand, the application area of ​​photovoltaic buildings accounts for less than 1% of existing buildings, and is mostly concentrated on industrial and commercial roofs. The main form is "BAPV". This method uses independent steel structures to support photovoltaic modules, which need to be built in steps after the construction is completed. There are problems such as high construction cost, long construction period, great safety hazards and great impact on the ecological environment. It only has the function of power generation and lacks other functions such as building structure and enclosure. On the other hand, building exterior wall decorative panels also have many disadvantages. For example, there are various ways to install stone, but the safety and quality are restricted by factors such as openings and panel weight. It is easy to break and the installation quality controllability is poor. Even if the development of connector technology allows stone to be separated from metal keels, there are still problems such as difficult installation and poor shock resistance. The non-metallic facing layer insulation building integrated panel has the risk of panel falling off, which can endanger life safety in serious cases and bring certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a building photovoltaic integrated product and installation method. Summary of the Invention

[0055] Example 1, as Figure 1-Figure 26As shown, when it is necessary to install a building photovoltaic integrated product, you can first choose to use a metal double cleaning bar 21 or a metal single cleaning bar 26 according to your needs. When the metal double cleaning bar 21 is selected, first, a plurality of metal double cleaning bars 21 are fixedly installed on the outer wall of the wall by expansion bolts 211 at equal intervals. Then, the first connecting piece 31 is inserted into the first square groove 22 slotted on the surface of the metal double cleaning bar 21, so that the horns of the first connecting piece 31 correspond to the first positioning hole 24 opened on the metal double cleaning bar 21 near the first square groove 22. Then, the second connecting piece 32 is installed. During the installation of the second connecting piece 32, the first through hole 33 on the upper side of the second connecting piece 32 corresponds to the position of the first positioning hole 24. Then, the first screw 38 is inserted. The positions of the first connecting piece 31 and the second connecting piece 32 are fixed. When the installation of one position is completed, the first connecting piece 31, the second connecting piece 32 and other structures at the corresponding position are installed synchronously according to the above steps. When the structure at the corresponding position is installed, a thermal insulation core material layer 42 is placed in the middle of the four adjacent groups of first connecting pieces 31 and second connecting pieces 32, and then the thermal insulation core material layer 42 is installed on the outer wall of the metal double pass bar 21 through the embedded bolts 36 and the fixing nuts 37. When the thermal insulation core material layer 42 is firmly installed, the positioning bolts 410 are passed through the hole on the lower side of the photovoltaic T-shaped piece 51 and are threadedly connected to the nuts 48 inside the five-sided concrete wrapped structural layer 43 to firmly secure the photovoltaic T-shaped piece 51. After the upper side of the photovoltaic panel 52 is stably installed through this structure, the second screw 56 is passed through the sixth positioning hole 57 to fix it to the lower side of another photovoltaic panel 52, and then the photovoltaic L-shaped member 55 is engaged with the positioning groove 53 on the adjacent photovoltaic T-shaped member 51 to achieve the stable installation of the two photovoltaic panels 52 on the wall. Or, when the production cost of the photovoltaic T-shaped member 51 is high, the photovoltaic T-shaped member 51 can also be replaced with a photovoltaic L upper piece 58 and a photovoltaic L lower piece 59. First, fit the side walls of the photovoltaic L upper piece 58 and the photovoltaic L lower piece 59, and then pass the positioning bolt 410 through it. The photovoltaic L upper piece 58 and the photovoltaic L lower piece 59 are threadedly connected with the nut 48 through the through holes opened in the side walls thereof, so as to stably install the photovoltaic L upper piece 58 and the photovoltaic L lower piece 59 on the outer wall of the concrete five-sided wrapped structural layer 43, and then the upper side of one photovoltaic panel 52 is fixed by passing the second screw 56 through the through hole on the upper side of the photovoltaic L lower piece 59. Then, when it is necessary to continue to install the photovoltaic panel 52 on the upper part of the current photovoltaic panel 52, one side of the photovoltaic L-shaped piece 55 is first inserted into the positioning groove 53 opened on the upper side of the photovoltaic L upper piece 58, and then the photovoltaic panel 52 on the upper side is supported by the photovoltaic L-shaped piece 55, and then the lower side of another photovoltaic panel 52 is fixed by passing the second screw 56 through the sixth positioning hole 57 in the photovoltaic L-shaped piece 55;

[0056] When the metal single cleaning bar 26 is selected, the expansion bolt 211 is first passed through the second cleaning bar fixing hole 28 to fix the metal single cleaning bar 26 to the wall, and then the first connecting piece 31 is inserted into the second square groove 27 slotted on the surface of the metal single cleaning bar 26, so that the horn of the first connecting piece 31 and the third positioning hole 29 opened in the metal single cleaning bar 26 near the second square groove 27 correspond to each other, and then the second connecting piece 32 is installed. During the installation of the second connecting piece 32, the first through hole 33 on the upper side of the second connecting piece 32 is aligned with the position of the third positioning hole 29, and then the first screw 38 is inserted to fix the position of the first connecting piece 31 and the second connecting piece 32. When one position is installed, the first connecting piece 31, the second connecting piece 32 and other structures at the corresponding position are installed synchronously according to the above steps. When the structure at the corresponding position is installed, the subsequent photovoltaic structure is installed according to the above structure.
