Claims

[Scope of utility model registration request]

A nut support arm and a bolt support arm are arranged so that they can move forward and backward on both sides of a flange having bolt holes for joining the segments, and can approach and separate from each other by sandwiching the flange, and the casing tip of the nut support arm A socket, which is rotatably driven by a motor via a gear transmission mechanism, is arranged in the part so that the axis of rotation of the socket can coincide with the center of the bolt hole, and a socket is provided on the surface of the socket facing the bolt support arm. , a nut fitting hole into which a nut can be freely inserted is formed centered on the rotational axis of the socket, and having a center on an extension of the rotational axis of the socket on a surface of the bolt support arm facing the socket; In a bolt fastening machine for segment assembly in which a bolt fitting hole into which a bolt head can be freely inserted is formed, the casing of the nut support arm is connected to a driving part casing including the motor and a driven part casing including the socket. A bolt fastening for segment assembly, characterized in that the bolt support arm is removably divided into a base end arm and a fastening arm having the bolt fitting hole. Machine.
