Claims

[Scope of utility model registration request]

A flange with an appropriate number of retaining protrusions projecting around the circumference is formed on the front outer circumferential surface of the insert bush, which is made of synthetic resin and has a substantially hollow cylindrical shape. is removably welded to the inner periphery of the rear end of the insert bushing, and a female screw is cut into a portion of the inner periphery of the insert bushing, while a through hole is formed in the hollow cylindrical hard rubber in the axial direction. Insert the formed bolt, insert the bolt head of the bolt into the insert bushing facing the bottom cover, and insert it into the formwork so that the drilled hole in the formwork and the female screw hole of the nut communicate with each other. A nut is welded to form a communicating hole, a male threaded portion of the bolt protruding from the insert bush opening is screwed into the communicating hole, and a hollow disc-shaped elastic member having water absorbing properties is inserted into the male threaded portion. A connecting structure of an insert bushing, characterized in that the insert bushing is fitted with a butterfly screw.
