At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, as well as after many ingenuity and experiments, auxiliary connectors for cylindrical concrete construction formwork are specially provided to solve the problem that the current auxiliary connectors cannot adapt well to curved walls and the installation speed is slow.
