This utility model discloses a roof wind-resistant component, relating to the technical field of wind-resistant components. It includes a support, with a connecting seat fixedly connected to the top of the support. Waterproof sheets overlap on both sides of the connecting seat. A groove is formed on the top of the connecting seat, and a pressure plate is positioned above the connecting seat. An
insertion hole is formed on the top of the waterproof sheet, and a rod is inserted into the
insertion hole. The rod is fixedly connected to the bottom of the pressure plate. Fasteners for securing the pressure plate are provided between the pressure plate and the connecting seat. A reinforcing cover is fitted over the pressure plate, and the waterproof sheet and reinforcing cover are fixed to the connecting seat via connecting components. This roof wind-resistant component, through the use of fasteners, connecting components, and reinforcing covers, provides multiple fixations to the waterproof sheet, forming an inclined support structure. This ensures the stability of the overall structure while preventing water accumulation at the support, thus improving the efficiency of the roof wind-resistant component.
