Formwork connecting device capable of being quickly assembled and disassembled and suitable for curved-surface fair-faced concrete structure

The invention discloses a formwork connecting device capable of being quickly assembled and disassembled and suitable for a curved-surface bare concrete structure, and relates to the technical field of constructions.The formwork connecting device comprises a rope fixing assembly, and the rope fixing assembly is connected with a fishbone-shaped composite straight tooth rod on the right side through a rope; the upper portion of the fishbone type composite straight toothed bar is connected with the two core self-locking devices in a clamped mode, the lower portion of the fishbone type composite straight toothed bar is meshed with the manual gear device, and the left sides of the core self-locking devices are connected with the tooth block fixing device in a clamped mode. And gear parts of the tooth block fixing device, the core self-locking device, the fishbone type composite straight toothed bar and the manual gear device are all located in the self-locking box body. The pre-tightening force is applied to elimi
