Specifically, the first patch layer 1 is made of pear paper, and the second patch layer 2 and the third patch layer 3 below are made of PVC plastic. The snow pear paper is also called tissue paper and copy paper, is named because the snow pear paper is generally used for wrapping snow pears, has the characteristics of semitransparent appearance, crisp quality and thinness, and can be cracked synchronously when the building 4 is cracked by attaching the snow pear paper on the surface of the building 4, so that a monitor can observe the crack condition of the building 4 conveniently through the cracking of the snow pear paper. The PVC plastic material is a polyvinyl chloride resin material, and has the advantages of incombustibility, high strength and weather resistance, and meanwhile, the PVC plastic material has good stability and high resistance.
