While achieving the convenience of taking materials, it also ensures that the roll film group 1 remains flat during the construction process, reducing the rolling caused by pulling, which leads to the disadvantage of a messy construction site.

[0026] The use method and advantages of the utility model: When the composite waterproof membrane with an anti-warping structure is used, the working process is as follows:

The limiting belt 3 on the surface can fit the thickness of the roll membrane group 1 due to the elastic expansion and contraction of the internal spring 4, which effectively ensures that the surface ground membrane 5 of the roll membrane group 1 is loosened due to rolling during use, causing a large amount of excess ground membrane 5 to unfold. During installation, the film covering paper under the adhesive layer 10 at the bottom of the first ground membrane 5 is peeled off, and it is attached to the surface of the construction site. When splicing the second ground membrane 5, the lower docking interface 12 of the second ground membrane 5 is laid flat on the first ground membrane 5. The lower part of the docking interface 11 is overlapped, and the film covering paper under the upper docking interface 11 is peeled off and bonded to the lower docking interface 12. By bonding the upper docking interface 11 and the lower docking interface 12, the tight laying of the ground membranes 5 can be completed. During use, the additional sound insulation layer 8 inside provides a good sound insulation effect, and the surface structure provides it with waterproofness. The sunscreen layer 9 is made of a material with added ultraviolet stabilizer, which can prevent ultraviolet radiation from damaging the inner layer and extend its service life. At the same time, the diamond-shaped concave-convex structure formed by the suture line can increase the contact area between the surface layer and the inner layer, improve its structural stability, thereby effectively maintaining its flatness and waterproof performance, and reducing the possibility of warping.
