Claims

[Scope of utility model registration request]

A large-diameter bolt head is provided at both ends of the connection bolt in series with the bolt neck, and a temporary stopper is provided at the intermediate portion in the length direction of the connection bolt to prevent the connection bolt from slipping, and an axis substantially perpendicular to the connection bolt is provided. A rotation operation hole that can be rotated with an operating tool such as a screwdriver is provided on one end surface in the length direction of the rotary connection body, and a large diameter hole larger than the bolt head is provided in the body of the rotation connection body. and a small-diameter hole having an opening larger than the bolt neck and smaller than the bolt head are provided in communication with each other in the circumferential direction, and a cam is provided in the small-diameter hole to draw the bolt head toward the rotating connection body as the distance from the large-diameter hole increases. A connection hole is formed in the central plate and side plates connected to both sides of the central plate are formed, and a connection bolt is inserted through the opening at the connection side end surface of the side plate. A through hole is formed in which the rotary connection body can be rotatably inserted, and a side hole is formed that communicates with the through hole in a direction substantially perpendicular to the through hole and opens on the side of the plate of the side plate material so that the rotary connection body can be inserted freely. , Temporarily fasten the connecting bolt to the connecting hole in the central plate through the temporary fixing body, and rotate the bolt head of the connecting bolt inserted through the through hole in the side plate to the rotating connecting body inserted into the side hole. A connecting structure for plate materials that is engaged with the cam portion that moves from the large diameter hole to the small diameter hole and draws toward the rotating connection body.
