（実施例）
以下、この考案を具体化した一実施例を第４〜
１４図に従つて説明する。(Example) Hereinafter, an example that embodies this idea will be described in the fourth to fourth embodiments.
This will be explained according to FIG.

強突部２７が打出し形成されている。 Figures 4 to 6 show a guide plate 21 as a reinforcing rib material, in which a vertically long (elongated) rectangular plate made of metal such as steel is bent in the vertical direction (longitudinal direction). The fixed part 22 and the guide part 23 are bent into a substantially L-shaped cross section along the bending line a-a, and are substantially perpendicular to each other.
is formed. The width of the guide portion 23 is approximately twice the width of the fixed portion 22, and the fixed portion 22 is stamped with protrusions 24 for spot welding, and the guide portion 23 is provided with guide holes 25. is transparent. A pair of grooves 26 (or one groove 26) is formed in the inner peripheral surface of the guide hole 25. Furthermore, a reinforcing protrusion 27 extending in the vertical direction is formed by stamping on the guide portion 23 between the folding line a-a and the guide hole 25.

形成されている。At a position corresponding to the reinforcing protrusion 27, a notch 28 is made in the fixed part 22 from its side edge to the folding line a-a, thereby reducing the weight of the guide plate 21 and saving material while maintaining mechanical strength. We are trying to Therefore, the notch 28 forms a protrusion 22a.

に形成する必要がある。 Further, a notch 29 is made in the guide portion 23 from the side edge to the middle portion so as to leave the area around the guide hole 25 and the reinforcing protrusion 27, thereby reducing the weight of the guide plate 21 and saving the material. Therefore, this cut 29 forms a protrusion 23a as a bulge. In addition, in order to maintain the strength of the guide plate 21, the cut 29 needs to be formed so as not to reach the folding line a-a.
さて、以上の様に構成されたガイド板２１は次

に無駄が生じない。 Now, the guide plate 21 configured as described above is manufactured as follows. As shown in FIG.
Cutting is performed sequentially along cutting line bb so that 23a is formed. Next, a guide hole 25 and a pair of grooves 26 are bored, and the reinforcing protrusion 27 and the protrusion 24 are formed while bending along the folding line a-a.
Therefore, the inner circumferential edge of the notch 28 and the outer circumferential edge of the protrusion 23a have the same shape, and the inner circumferential edge of the notch 29 and the outer circumferential edge of the protrusion 22a have the same shape, so that no material is wasted.

い。 Further, in this embodiment, the portion where the guide portion 23 is easily deformed due to the notches 28 and 29 is replaced by the reinforcing protrusion 27.
Since the guide hole 25 and the surrounding portion thereof are reinforced by the guide hole 25, deformation and change in position can be prevented without increasing the plate thickness. Furthermore, since the reinforcing protrusions 27 are formed by stamping as described above, the weight does not increase due to the reinforcing protrusions 27.

周辺部分の変形を防止する効果が向上する。 Note that even if the plate thickness is made thinner, by providing the reinforcing protrusion 27, it is possible to reduce the weight and material while preventing deformation of the guide hole 25 and its surrounding area. Furthermore, if the plate thickness is the same as that of the conventional guide plate 21, the weight of the guide plate 21 remains the same and the effect of preventing deformation of the guide hole 25 and its surrounding area is improved.

る。 Flat concrete molding surface 31 made of steel plate
A reinforcing frame 32 is formed on the upper and lower edges of the formwork main body 31 having a shape 31a, which is bent toward the side opposite to the concrete molding surface 31a. A pair of square pipe-shaped connecting members 33 extending in the vertical direction are welded and fixed to both sides of the form body 31 on the side surfaces of the reinforcing frame 32.
A connecting hole 34 is transparently provided in the connecting member 33 . Further, the guide plate 21 of this embodiment is attached to the fixing part 22 on the form body 31 facing one of the connecting members 33.
The guide hole 25 corresponds to the connecting hole 34, and the guide hole 25 corresponds to the connecting hole 34. Connection hole 3
4 and the guide hole 25, a connecting rod 35a is inserted and supported so as to be rotatable and movable in the lateral direction, and a U-shaped clamping portion 35b is fixedly attached to the connecting rod 35a. Further, the connecting rod 35a is provided with a protrusion 35c so as to be able to pass through the groove 26 of the guide hole 25, and the connecting pin 35 is constituted by the connecting rod 35a, the clamping portion 35b, and the protrusion 35c. Note that three reinforcing ribs 36 are welded and fixed to the back surface of the form body 31.

孔３４内から外れることはない。 Now, in order to connect two concrete formworks 30 adjacently, as shown in FIG.
5a, and both connecting members 3 are connected by the clamping portion 35b.
Hold 3. Furthermore, the clamping portion 35b is connected to the connecting member 33.
After the connecting pin 35 is rotated clockwise in FIG. 11 so as to be released from the connecting rod 35, the connecting rod 35 is moved to the right as shown in FIG. 12, and the clamping state of both the connecting members 33 is released. In this case, the connecting rod 35a does not come out of the connecting hole 34 due to the contact between the protrusion 35c and the guide plate 21.
さらに、第１３図に示すように、挾持部３５ｂ

である。 Furthermore, as shown in FIG.
Rotate the connecting pin 35 upward so as to lift it upward, and with the protrusion 35c placed in a position corresponding to the groove 26 of the guide hole 25, move the connecting pin 35 to the right as shown in FIG. When moved, the protrusion 35c passes through the groove 26 and the connecting rod 35a is removed from the connecting hole 34. Then, by moving the connecting pin 35 from this state to the front left, the connecting pin 35 can be separated from the concrete formwork 30. In this case, as shown in FIGS. 11 and 13, the guide hole 25 is smaller than the diameter of the connecting rod 35a.
There is no problem as the diameter is made large to allow for some margin. Also, connect the connecting pin 35 in the reverse order to that described above.
can be attached to the concrete formwork 30. Therefore, the damaged connecting pin 35 can be replaced.

る。従つて、コンクリート型枠３０の寿命が長く
なる。 A deforming force is applied to the guide plate 21 used in the above manner by operating the connecting pin 35. Further, as is well known, when concrete is poured, concrete pressure is applied to the concrete forming surface 31a, and this also applies deformation force to the guide plate 21. However, by providing the reinforcing protrusion 27 on the guide plate 21, the guide plate 21 becomes difficult to deform. Therefore, the life of the concrete formwork 30 is extended.

Further, a plurality of short reinforcing protrusions 27 may be arranged intermittently.
