A lot of labor is required. As my country's aging population continues to intensify and resources and energy continue to be strained, traditional construction methods no longer meet the requirements of social development. In recent years, with the continuous improvement of people's living standards, people's requirements for construction speed, construction cost, construction quality, energy conservation and environmental protection of residential and other construction industries have also been continuously improved, and they are gradually moving towards modern prefabricated building systems. The prefabricated structure can be prefabricated in the factory and assembled on site to realize the industrialization of housing. At the same time, it can effectively improve the efficiency of materials in building energy saving, structural performance and structural performance, save energy and resources, reduce construction waste and adverse effects on the environment, and reduce construction. Site restrictions, etc. The industrialization of construction is the development direction of the construction industry in the future, and the prefabricated building is also a hot spot that major construction companies are competing to study in recent years. In order to improve the integrity of the prefabricated building, the key is to deal with the connection between the components.
