Deformation joint formwork erecting device and using method thereof

The invention relates to a deformation joint formwork erecting device. The deformation joint formwork erecting device comprises a deformation joint formwork assembly which is connected with a deformation joint through-wall bolt assembly. The deformation joint formwork assembly comprises an outer formwork which comprises two end plates and middle plates, and the two end plates comprise the left plate and the right plate. The middle plates are arranged between the left plate and the right plate. Tongue and groove joints are arranged, so that the corresponding middle plate and the left plate are mutually attached, the corresponding middle plate and the right plate are mutually attached and the adjacent middle plates are mutually attached. Through the deformation joint formwork erecting device, the problems that constitution is complex, the cooperative effect between an inner formwork and the outer formwork has large influences on firmness, construction efficiency is low and the circulation rate is low are solved; in addition, safety and reliability are achieved, and the requirements of practical building construction are met.
