Claims

[Scope of Claim for Utility Model Registration] (1) A flat plate part with a bolt insertion hole formed in the center, and a lower chord of self-supporting truss-shaped reinforcing bar that is bent upward from both ends of the flat plate part and is connected to the upper end. a first member consisting of a pair of upright plate parts formed with bent parts to be placed; a flat plate part facing the upper surface of the flat plate part and having a bolt insertion hole formed in the center; a second member consisting of a pair of rising plate parts that are bent and connected upward and have a bent part formed at the upper end to press the lower chord; and a second member formed in the floor slab driving form from below. a bolt that is inserted through the through hole and the bolt insertion holes of the first and second members, a washer of the bolt, and a portion of the bolt that protrudes upward from the flat plate portion of the second member. A connecting device for a floor slab driving form and a self-supporting truss-shaped reinforcing bar, comprising a mating nut. (2) A flat plate part with a bolt insertion hole formed in the center, and a bent part that is bent upward from both ends of the flat plate part and welded to the lower chord of the self-supporting truss-shaped reinforcing bar at the upper end. a bolt inserted from below the floor slab driving formwork across a through hole formed in the formwork and a bolt insertion hole in the fixing member; A device for connecting a floor slab driving form and a self-supporting truss-shaped reinforcing bar, comprising a bolt washer and a nut that is screwed into a portion of the bolt that protrudes upward from the flat plate portion. (3) Claim (1), wherein the nut is a bag nut; or
A connecting device for floor slab driving formwork and self-supporting truss-shaped reinforcing bars as described in (2).
