Claims

[Scope of utility model registration request]

The outer formwork is formed by planting left and right side plates whose upper open parts can be tilted on the bottom plate, and both end plates with clamping pieces that can be slid back and forth, and which has a predetermined gap groove. A formwork main body consisting of an inner formwork formed with a certain size and shape, a U-shaped socket whose open end portions are pivotally connected to bearings, and an inner side of this socket. It consists of two arms, one end of which is rotatably connected to each other at approximately the center of the socket, and a connecting pin with a bolt socket arranged between the other ends of the arms is rotatable. The linkage mechanism includes a coupling pipe that extends freely and is welded to the central part of the back of the U-shaped socket for inserting and connecting a lever of an appropriate length into the hollow hole of the socket, and A concrete product characterized in that the link mechanism part and the formwork body are connected in series by welding and fixing the bearing part to the end plate of the formwork body and connecting the protruding end of the connecting rod to the bolt socket. Formwork for molding.
