Problems solved by technology

[0002] At present, the connection methods of prefabricated buildings mainly include sleeve grouting connection, welding, mechanical connection and lap joint connection with reserved holes. The current construction method has a large amount of pouring, resulting in a large waste of materials and labor, and the maintenance of post-cast concrete It takes a long time to affect the construction period, it is difficult to guarantee the quality of on-site welding, the hoisting points of prefabricated components are not accurate, and the requirements for supporting conditions are relatively high.
