  However, the above-described conventional wooden residual form hanging bracket has the following problems.

(A) The folded portion of the wooden residual mold hanging bracket is engaged with the rising wall of the support member, and a large force is applied to the folded portion. That is, the folded portion may open in a direction away from the rising portion as indicated by a chain line in FIG. In order to prevent such deformation of the folded-back portion, the conventional wooden residual mold hanging bracket is formed of a thick material as a whole.

  However, when the entire wooden residual form fitting is made of a thick material, the weight of the wooden residual form fitting is increased, which increases the manufacturing cost and the transportation cost and makes the handling troublesome.

(B) Since the base portion of the conventional wooden residual form bracket has a substantially rectangular shape, the storage bag may be broken when the wooden residual form bracket is stored in the storage bag. At the same time, there is a risk that an operator may injure his / her hands and feet during assembly of the remaining wooden form.

The present invention solves the above-mentioned problems in the conventional wooden residual mold hanging metal fitting, and provides the wooden residual mold by giving sufficient strength while forming the entire wooden residual metal fitting hanging from a thin material. Reduce the manufacturing and transportation costs of the frame brackets and make them easier to handle. In addition, workers may be injured during the assembly of the wooden residual formwork due to the wooden residual formwork bracket. It was made to try not to.

In order to solve the above-described problems, the present invention provides the following wooden residual form fittings.

(1) In a wooden residual mold hanging metal fitting provided with a rising portion at one end of a base portion provided with a fixing tool insertion hole, and forming a folded portion at the upper portion of the rising portion,
The wooden folded mold hanging metal fitting (Claim 1), wherein the folded portion is formed by folding both side edges of a plate-like body outward of the folded portion.

  “Outward of the folded portion” refers to the direction toward the outside of the folded portion, that is, the direction from the folded portion toward the symbol a in FIG. Incidentally, the direction from the folded portion toward the symbol b in FIG. 2 is the inside of the folded portion.

(2) A rib is provided at a bent portion between the base portion and the rising portion (Claim 2).

(3) The other end of the base is formed in a substantially semicircular shape.

[Convention of claim 1]
Since the folded portion is formed by folding both side edges of the plate-like body, the strength of the folded portion is increased. Therefore, the wooden residual form fitting may be formed of a thin material. That is, even when the whole wooden residual form fitting is lightened by using a thin material, sufficient strength can be provided. As a result, it is possible to reduce the manufacturing cost and the transportation cost of the wooden residual form hanging bracket and to make the handling easier.

  Since the folded portion is formed by folding both side edges of the plate-like body not to the inside of the folded portion but to the outside of the folded portion, the rising portion is brought into close contact with the rising wall of the support member such as the shape steel. Can do. See FIG. 5 and FIG. That is, as shown in FIG. 3, the folded portion is formed by folding both side edges 21a and 21b of the plate-like body 21, and therefore the folded portion 19 is formed on both side edges 21a of the folded plate-like body 21. The side edges 21a and 21b of the plate-like body 21 are folded outward from the folded portion 19, so that the side edges 21a and 21b are It does not protrude inward of the folded portion 19. As a result, since the rising portion can be brought into close contact with the rising wall of the support member such as a shape steel, the position of the fixing tool insertion hole of the base portion can be brought close to the rising wall of the support member. In other words, the fixing tool can be driven into a position close to the support member in the rod-shaped wood. Therefore, the rod-like wood is more firmly fixed to the support member.

[Convention of claim 2]
Since the rib is provided at the bent portion between the base portion and the rising portion, the strength of the wooden residual form fitting is further improved.

[Convention of claim 3]
Since the other end of the base is formed in a substantially semicircular shape, there is no possibility that the storage bag will be torn when the wooden residual form bracket is stored in the storage bag. In addition, there is no risk that an operator may injure the limbs during assembly of the remaining wooden form.
