Background technique

The traditional cast-in-place construction method has a low degree of industrialization, poor construction conditions, time-consuming and labor-intensive, and it is difficult to ensure quality, and safety accidents often occur in construction projects. The use of prefabricated structures can greatly reduce construction waste, reduce noise pollution, reduce labor consumption and strength, effectively improve the construction environment, and improve project quality. The application of prefabricated concrete structures can achieve the goal of energy conservation and emission reduction, improve people's quality of life and the level of ecological civilization, promote the transformation of urban and rural construction models and building development methods, and produce obvious benefits for economic and social development.

There are a large number of splicing vertical joints and horizontal joints in the exterior wall of prefabricated buildings, and leakage of splicing joints is easy to occur. At the same time, the characteristics of composite thermal insulation exterior wall panels are not easy to repair, which greatly increases the difficulty of leakage control of prefabricated buildings. Therefore, the key to waterproofing of prefabricated buildings is the sealing and waterproofing of external wall joints. The waterproofing of the vertical slab joints of the prefabricated exterior walls of prefabricated buildings generally adopts two waterproof measures that combine structural waterproofing and material waterproofing. Effect.
