[0001] The utility model relates to the technical field of waterproof coiled materials, and more specifically to a new type of waterproof coiled material in building construction projects. Background Technique

[0002] Building construction projects refer to all engineering activities related to the construction and renovation of houses. This includes the entire process from planning, design, construction to maintenance and management. There are various types of building construction projects, covering various building forms such as residential, commercial, industrial, and public facilities. During the construction of a house, it is necessary to lay waterproof coiled materials on its roof to play a waterproof role. Waterproof coiled materials are building materials used to prevent water penetration. They are made of various materials, including asphalt, polymers, rubber, and metals, and have good water resistance and durability.

[0003] For example, a new type of asphalt waterproof coiled material with the publication number CN214727109U in the prior art can increase the protection of the asphalt waterproof coiled material during storage, and at the same time increase the waterproof property and toughness of the asphalt waterproof coiled material, and improve the service life of the asphalt waterproof coiled material.

[0004] However, the above prior art still has the following problems when in use: When laying the waterproof coiled material, the staff usually needs to cut the waterproof coiled material according to the roof area, and the staff needs to carry a cutting device with them, which is very inconvenient to use. At the same time, due to the soft material of the waterproof coiled material, when the staff manually cuts, the waterproof coiled material is prone to deviation, affecting the cutting flatness. Based on this, the utility model provides a new type of waterproof coiled material in building construction projects. Content of the Utility Model
