Claims

[Claims for Utility Model Registration] 1. In order to maintain the spacing between concrete formworks installed facing each other, a concrete formwork spacing holder interposed between the concrete formworks is provided with a strip-shaped spacing maintenance device. At least one side edge of the tool body 1 is bent with an inner regulating piece 2.3 that regulates the space between the inner surfaces of the concrete formwork, and the space between the inner regulating pieces 2 and 3 is equivalent to the thickness a of the formwork. Bend the outer regulating pieces 4 to 7 in the same direction as the inner regulating piece 2.3 on the same side edge as the inner regulating pieces 2 and 3 so that a gap is formed between the inner regulating piece 2 and the interval holder body 1. Height b of reinforcing ribs of formwork
Concrete form spacing characterized in that bendable locking pieces 8 to 11 are provided on the inside of the outer regulating pieces 4 to 7 to protrude toward the inner regulating piece 2°3 so as to form an interval corresponding to . Retainer. 2 The inner regulating pieces 2 and 3 are a pair, and are bent in opposite directions on both side edges of the spacer main body 1, and the outer regulating pieces 4
-7 are four pieces, each of which is bent at both ends of both side edges of the spacer main body 1 so as to sandwich the inner regulating pieces 2 and 3, respectively.Claim 1 of Utility Model Registration Concrete form spacing retainer as described in section. 3. The concrete form spacing holder according to claim 2, wherein slits 12 to 15 are cut into the outer regulating pieces 4 to 7 to make it easier to bend the locking pieces 8 to 11. 4 Insertion holes 16 for inserting wedge rods 45 and 46 at both ends of the spacer main body 1 so as to be in contact with the outer surface of the formwork.
．． 17. The concrete form spacing holder according to claim 2 or 3 of the claimed utility model registration.
