2. Description of the Related Art FIG. 5 shows a conventional example of a construction method in which plywood concrete casting forms are butted against each other as a typical example of a panel structure. This formwork 20
Has a structure in which a splint 22 is nailed and fixed to a peripheral edge portion on the back side of the plywood 21, and the front side of the plywood 21 is a concrete placing surface. Then, in order to obtain a casting surface having a required area, a plurality of molds 2 whose edges are abutted against each other are used.
A nail 23 was struck between the adjacent piers 22, 22 of 0 to connect them to each other.

[0003]

However, the above-mentioned conventional formwork connecting methods have considerable drawbacks as listed below. (A) Plywood 21 and pier 2 when separating the used formwork into pieces one by one using a burl for repeated use.
2 which is damaged or nailed to plywood 21
It was easy for 2 to lean. In addition, it takes time to remove the nails that have been driven in, and the nails that have been removed are scattered, which is dangerous. (B) Wood resources tend to be depleted in the world, and even if the pier 22 is damaged, replacement costs will be high if a new repair is made at each site, and it is becoming difficult to replace it. (C) Then, when the formwork 20 is reused when it is damaged or the mounting state of the skate 22 is inclined, a gap is created at the abutting points of the formwork and burrs are generated on the placing surface of the concrete. There was also the problem of worker health management, inhaling dust during removal. (D) The formwork 20 is usually used repeatedly, but it is bulky because the stiles 22 are fixed to the plywood 21, and it costs a lot to store and transfer it. It was a major factor that prevented the construction cost of the casting form from being reduced. Therefore, the inventor of the present invention has devised a metallic "reinforcing / connecting device for a panel-like structure" having a completely unique configuration that can solve the above-mentioned various problems, and previously Japanese Patent Application No. 1-258452 >>. The object of the present invention relates to a reinforcing / connecting tool for a panel-like structure, which has been improved with the object common to the invention of the prior application.
