This utility model has beneficial effects such as improving construction efficiency and strong adaptability.

[0004] Although the aforementioned patent can clamp the edge of the waterproof membrane body between the substrate and the clamping member, when clamping the waterproof membrane, since the edge of the waterproof membrane body is clamped between the substrate and the clamping member, there is a gap between the waterproof membrane body and the roof at the clamping position, which will affect the waterproof sealing performance.

[0005] Therefore, there is an urgent need for waterproof membrane fixing devices for roofs to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that after clamping, there is a gap between the waterproof membrane body and the roof at the clamping position, which affects the waterproof sealing performance. Therefore, this invention proposes a waterproof membrane fixing device for roofs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:
