[0002] With the rapid development of my country's construction industry, the application of building exterior walls has also been widely prevented, but it also brings the problem of exterior wall leakage. Leakage will not only affect the functional design of the building, but also seriously affect its aesthetics. For this reason, my country spends a lot of manpower and material resources in the field of building anti-seepage every year. The traditional anti-leakage method is usually to apply sealant or fill cement in the joints of adjacent exterior walls. Among them, the method of applying sealant will gradually weaken the effect of the sealant over time, resulting in a significant decrease in anti-leakage ability. The method of filling cement may cause rigid extrusion between adjacent exterior walls during an earthquake, which is easy to cause cracks in the exterior walls. Utility Model Content
