The use of the medium-pressure metal roof in civil buildings and public buildings is more and more extensive. At present, the requirement on the waterproof performance of a metal roof is higher and higher, and particularly when a roof pipeline or an axial flow fan 11 needs to be placed on the roof, the waterproof performance of the connection between the fan 11 and a profiling roof panel 12 is more important. Currently, the popular practice of the industry is shown in fig. 1 and 2, which includes: a profiled roof panel 12 for roof waterproofing and protection; the drainage piece 14 is used for draining water from the upstream of the contour plate roof to the two sides of the base 13; the base 13 is made of metal and is connected with the profiling roof panel to prevent rainwater from entering the inside of the hole; the fan 11 is divided into a power fan and an unpowered fan and is used for pumping indoor hot gas or harmful gas out of the room; the pressing plate 18 is used for connecting and fastening the roof panel and the lining plate; the lining plate 15 is positioned below the drainage piece and the profiling roof plate, and is connected with the profiling roof plate and the drainage piece after being internally paved with waterproof materials; and the connecting nails 16 are used for connecting the roof board and the lining board or connecting the lining board and the flow diverter together. The key technology here is that the base 13 is formed by bending and welding thin metal sheets to form the base 13, which is then connected to the profiled roof panel 12 by built-in connection with the sealing material therebetween. The connection mode does not expose any connection nail 16; the waterproof effect is fully ensured. However, when the base 13 is wide, the wave crest portion of the profiling roof panel 12 on the upstream side needs to be cut off, and the drainage member 14 and the lining plate 15 need to be arranged, so that rainwater on the upstream side can be guided to the two sides of the base 13 and drained to the lower end of the base 13. The flow guides 14 and the backing sheets 15 and the profiled roof panels 12 are lined with sealing material and connected together by connecting nails 16. And the lower extreme of base 13 can be according to the crest current situation of roof boarding 12, leaves corresponding breach, through built-in connection back, has had fine waterproof performance. As can be seen from the construction diagrams shown in fig. 1 and 2, the joint between the conventional profiled roof panel 12 and the base 13 has the following problems: a large number of connecting nails 16 are exposed out of the connection between the drainage piece 14 at the front end of the base 13 and the base 13, and a water leakage hidden trouble is left; the drainage piece 14 is connected with the lining plate 15 through the connecting nails 16, a large number of connecting nails 16 are exposed, and the hidden trouble of water leakage exists; the connection of the profiling roof board 12 and the lining board 15 exposes a large number of connecting nails 16 and leaves water leakage hidden trouble; the corrosion of the notch of the profiled roof panel 12 cut on site at the front end of the base 13 seriously affects the service life of the roof panel 12 and can also cause the corrosion of the lining plate 15 and the drainage piece 14; the cut wave crest of the profiling roof panel 12 is provided with a hole, a sealing plug 17 is generally arranged at the position, and the reliability of waterproof plugging always troubles the industry, and other technical problems.
