Description

Technical Field

[0001] The utility model relates to the technical field of BIPV building photovoltaic integration, in particular to a profiled plate locking structure for installing photovoltaic components. Background Art

[0002] Metal corrugated sheet roofs are widely used in large-space and large-span buildings. However, due to the strong ductility and large elastic deformation capacity of metal sheets, the creep accumulation caused by the repeated action of positive and negative wind pressure for a long time causes the gap between the roof panel and the support to become larger, the connection point gradually loosens, and the wind resistance capacity decreases. Therefore, it is necessary to improve the restraint position of the corrugated sheet to prevent the accumulation of creep caused by adverse deformation, and to improve the wind resistance of the metal corrugated sheet and the durability and reliability of the wind resistance capacity.

[0003] Polymer waterproofing membranes have become an indispensable component in the construction of metal roofing systems. Due to the characteristics of the metal roofing installation process, if the polymer waterproofing membrane is laid under the roof, the self-tapping screws that fix the roof panel support will inevitably penetrate the waterproofing membrane. Even if each nail hole is repaired, after the metal roof panel is installed and covered, the repaired nail holes will all be hidden under the roof. Once the nail holes are not repaired in place, the hidden danger of leakage points will be basically impossible to find. What's more, the number of self-tapping screws used in the roof support is huge, and the repair of each nail hole will consume a lot of manpower and time, greatly increasing the construction cost of the metal roof.

[0004] Therefore, we propose a corrugated plate locking structure for installing photovoltaic modules in order to solve the above-mentioned problems. Summary of the invention

The support 2, bottom fixing part 3, anti-twist limit assembly 4, anti-slip limit part 5 and upper pressure code 6 can avoid electrochemical corrosion by selecting different materials or spraying insulating coating and anti-corrosion coating on the surface.

[0050] Reference Figure 4 , press the profiled plate 1 downward into the support, Figure 5 The middle pressure profile 1a shrinks and deforms, squeezing into the support 2; Figure 6 The middle profiled plate 1a rebounds in the support 2, the profiled plates 1d and 1e are deformed, and the opening distance between the profiled plates 1b and 1c increases; Figure 7 The middle support 2 is stepped and slides into the corrugated plates 1b and 1c. Figure 8 The intermediate pressure profile plate 1 deforms and rebounds to restore its original size and fits with the support 2.

[0051] Reference Fig. 9 , the stainless steel bolt 10 passes through the bottom fixing piece 3 and is placed in the limiting groove of the corrugated plate 1.

[0052] Reference Fig.10 The bottom fixing part 3 is rotated 90° in the slide groove of the corrugated plate 1, and the anti-twist limit assembly 4 is inserted into the stainless steel bolt 10 and stuck on the bottom fixing part 3, so that the bottom fixing part 3 can no longer rotate.
