[0002] With the development of environmental problems, the country has implemented a sustainable development strategy, issued a call for energy conservation and emission reduction, and developed solar energy green environmental protection. Photovoltaic building integration (BIPV) has been rapidly developed as a new concept of solar power generation. Photovoltaic building integration installs solar photovoltaic power generation arrays on the outer surface of the building's enclosure structure to provide electricity. Photovoltaic building integration is suitable for most buildings, such as roofs, curtain walls, ceilings, etc. For building-integrated roof power generation systems, it has very strict requirements for waterproofing. The existing waterproofing measures mainly set up water guides in the fixed brackets of photovoltaic panels to drain water, so that concrete and color steel tile roofs are not eroded by water.

[0003] To build a photovoltaic building integrated power generation system on a concrete roof, you need to install the foundation and bracket first, and then install the primary and secondary water channels and components on the bracket. The main water channel needs to be effectively connected to the bracket beam, which is a U-shaped steel. The edge of the main water channel is connected to the curling of the bracket beam, which is generally fixed by self-tapping screws. This method has the advantages of simple construction methods and the disadvantages of high installation difficulty due to the limited curling size of the bracket beam.

[0004] Therefore, it is urgent to improve and upgrade the curling connection method between the edge of the main water tank and the support beam to directly improve the efficiency of on-site construction. Utility Model Content
