Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a flame retardant polymer waterproof coiled material. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] In the prior art, such as the patent with publication number CN214563498U, a polymer flame-retardant waterproof membrane is disclosed. The flame-retardant waterproof membrane inserts the positioning plate on the waterproof membrane body A into the positioning groove in the waterproof membrane body B, and then inserts the insertion rod into the through hole on the outer surface of the waterproof membrane body B. The outer surface of the limit column fits with the inner wall of the through hole and the slot, and the spring is compressed until the limit column contacts the slot. The spring restores the elastic deformation to push the limit column toward the inside of the slot, and the limit column is stuck on the inside of the slot. The waterproof membrane body A and the waterproof membrane body B are overlapped and the overlap is stable. Then, glass glue is sprayed in the gap between the waterproof membrane body A and the waterproof membrane body B to seal the gap to prevent water leakage in the gap and improve the waterproof effect.

[0004] During the overlapping process of the above-mentioned waterproof membrane, only the overlapping of the side joints of the two sets of waterproof membranes is considered. However, when the length of the waterproof membrane is not enough, the front and rear ends of the waterproof membrane also need to be spliced. At this time, the above-mentioned waterproof membrane does not fully consider the overlapping problem of the front and rear ends, resulting in leakage at the front and rear end joints of the waterproof membrane in actual applications, affecting the overall waterproof effect. Utility Model Content
