[0002] As a pillar industry in my country, the construction industry has made important contributions to my country's economic development. However, traditional wet construction has always had problems such as long construction period, low efficiency and high pollution. In recent years, with the country's proposal of the concept of green development, the traditional construction industry has considered the combination of economic development and environmental protection. Prefabricated buildings refer to buildings that are prefabricated in part or in their entirety in a factory and then transported to the construction site and assembled into a whole using effective connection methods. Because prefabricated buildings can be prefabricated in factories, they have the advantages of high industrialization, high construction efficiency and low pollution, meeting the development needs of "Green China" at this stage.

[0003] However, the existing prefabricated concrete structures have the following shortcomings: 1. The system is not fully assembled, with some structural components assembled and some cast-in-place; 2. The nodes are partially cast-in-place, and the traditional prefabricated system node connection is connected by steel sleeves, and the formwork is set up and concrete is poured on site for node connection; 3. The process is complicated, and traditional cast-in-place components such as beams and floor slabs also need to use traditional steel bars, formworks, concrete, maintenance, and demolding methods, which are complicated; 4. There are many node quality problems, and the components are connected by cast-in-place concrete, which is prone to concrete quality problems; 5. The cycle is long, and it takes a lot of time to set up scaffolding, support formwork, tie steel bars to support formwork, increase concrete strength, and remove scaffolding and formwork. These shortcomings need to be solved urgently to meet the current demand for the rapid development of prefabrication. Summary of the invention
