[0002] With the development of modern industrial technology, houses can be built in batches and sets like machine production. As long as the prefabricated house components are transported to the construction site and assembled, it is the so-called prefabricated building. Prefabricated buildings began to arouse people's interest in the early 20th century and finally came into being in the 1960s. Due to the fast construction speed and low production cost of prefabricated buildings, they have been rapidly promoted all over the world. Prefabricated buildings can greatly reduce construction waste and protect the environment through factory production and on-site assembly construction. At the same time, they can reduce construction noise, improve the engineering quality and environmental quality of buildings, improve the labor productivity level of engineering construction, and achieve sustainable development of buildings. With these advantages, the industrialization of prefabricated buildings has been gradually promoted and widely used in residential buildings.

[0003] At present, for the connection structure in the wall panel structure system, the connection method used is mainly to use aluminum or wooden formwork to support the vertical connection parts of adjacent prefabricated wall panels on site, and connect them through cast-in-place concrete. However, this connection method makes its assembly connection efficiency low and requires multiple construction workers to implement it, which has a high labor cost. Therefore, a vertical connector of prefabricated wall panel components is proposed to solve the above-mentioned problems. Utility Model Content
