Reinforcing bar cages connected by spacers are buried. Also, since the ALC panel uses bolts when it is attached to the body,
For example, as disclosed in Japanese Examined Patent Publication No. 6-33642, a fitting including a nut and a reinforcing bar fixing member having a U-shaped cross section for fixing the nut is welded to a predetermined position in advance.

The fittings are welded to the rebar mat before the rebar cage is formed, or are welded to the rebar cage after forming the rebar cage from the rebar mat. And insert the reinforcing bar welded mounting bracket into the form,
By mounting mortar on the formwork, the mounting bracket is ALC
It is placed at a preset position on the panel.

[0004]

As described above, in the mounting bracket embedded in the ALC panel, the variation in the mounting position of the nut is within the preset tolerance range, and the verticality of the nut is guaranteed. It is required to satisfy the above conditions. In order to satisfy this requirement, it is necessary to accurately set the position and posture when the mounting bracket is welded to the reinforcing bar mat or the reinforcing bar cage. Therefore, there is a demand for the development of a device capable of welding a mounting bracket while maintaining a stable position and posture and welding the reinforcing bar cage.

An object of the present invention is to provide a positioning jig which can ensure the position and posture of the nut of the metal fitting when the fitting is mounted on the reinforcing steel body consisting of a reinforcing bar mat or a reinforcing bar cage, and to position and mount the reinforcing steel body.
