as shown in fig. 6, a buffer 7 can be further arranged between the bottom of the photovoltaic panel 3 and the horizontal part in the right-angle bracket 2, a foam rod 8 is embedded in the inner right-angle part of the right-angle bracket 2, and a sealant 9 is injected into the gap; the vertical part of photovoltaic board 3 and right angle support 2 reserves certain clearance, can prevent through reserving certain clearance that the photovoltaic board from appearing warping and the condition emergence of the lateral wall of extrusion right angle support 2 in the use.
Injecting sealant 9 into all gaps, injecting sealant into the transverse gaps, and injecting sealant into the longitudinal gaps, so that rainwater can be drained along the grooves of the longitudinal gaps in time when raining; the sealant is extruded out of the glue injection gun nozzle in a cylindrical shape uniformly and continuously, the gun nozzle moves uniformly and slowly, the sealant is filled in the gap, and bubbles or cavities caused by too fast movement of the glue nozzle are prevented. And immediately modifying after glue injection is finished, pressing redundant sealant at the joint into the joint by using a scraper, removing the second T-shaped positioning piece 6 according to the actual condition after the glue joint strength reaches 70%, and leaving the first T-shaped positioning piece 4 in the glue joint.
Finally, the wind caps 22 are buckled on the right-angle support 2, and a pulling rivet is respectively arranged in the middle of each of two sides of each wind cap to prevent the wind caps from being blown away by strong wind.
According to the photovoltaic roof installation method provided by the embodiment, a production line type operation mode can be formed by improving the traditional construction method and adding some necessary auxiliary measures, so that the labor intensity is reduced, and the labor efficiency is improved. By adopting the installation method of the photovoltaic roof provided by the embodiment for construction, the construction efficiency can be improved by 1-2 times. Engineering examples prove that the installation method has advancement, universality and operability.
In summary, the installation fitting of the photovoltaic panel, the installation method and the photovoltaic roof provided by the invention comprise a first supporting beam; the right-angle support is arranged on the first supporting beam, and the right-angle support and the first supporting beam are used for supporting a photovoltaic panel; and the first T-shaped positioning piece is movably arranged on the right-angle support and used for fixing the distance between two adjacent photovoltaic panels. The problem that the distance between photovoltaic panels is not easy to control and the location is difficult when the photovoltaic panels are installed can be easily solved by the arrangement of the first T-shaped positioning piece, the first T-shaped positioning piece is simple to use, only needs to be movably arranged on the right-angle support, and the second T-shaped positioning piece is used for limiting the location of the temporary unfixed photovoltaic panels and preventing the photovoltaic panels from sliding downwards. When the installation fitting of the photovoltaic panel is used for installing the photovoltaic panel, the construction efficiency can be greatly improved, the installation construction quality can be ensured, and the cost is saved.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
