[0004] Next, the horizontal reinforcing bar 12 which is passed in the horizontal direction is suspended on a lifting plate 14 via a rope 13 in advance, and the lifting plate 14 is lifted by a crane 15. The suspended lifting plate 14 is gradually lowered, and the horizontal reinforcing bars 12
The crane 15 is stopped at a position orthogonal to the vertical reinforcing bar 11 already set up.

[0005] Next, as shown in FIG. 7, each of the three vertical reinforcing bars 11 and the horizontal reinforcing bars 12 are firmly connected to each other by wires using wires 16.

[0006] One horizontal reinforcing bar 12 is connected to a vertical reinforcing bar 11 by a wire 16.
After that, the other horizontal reinforcing bars 12 are similarly connected to each of the three vertical reinforcing bars 11 by wires 16 above the horizontal reinforcing bars 12.

[0007] By repeating such operations a required number of times, a lattice-shaped reinforcing bar unit formed by connecting the vertical reinforcing bars 11 and the horizontal reinforcing bars 12 is formed on the base 10.

[0008]

As described above, according to the conventional method, the horizontal reinforcing bars 12 must be attached one by one to the vertical reinforcing bars 10 previously mounted on the base 10 in order. The working time became extremely long, and the working efficiency was remarkably lacking.

First, a plurality of reinforcing bar hanging bands are arranged on the ground in parallel with each other, and the same number of horizontal reinforcing bars as the reinforcing bar fixing devices are placed on these reinforcing bar hanging bands so as to be orthogonal to each reinforcing bar hanging band. Next, the horizontal reinforcement placed on the reinforcement suspension band is fastened to the band main body via each reinforcement fixing device. Thereby, a plurality of horizontal reinforcing bars (the same number of horizontal reinforcing bars as the reinforcing bar fixing device) are fastened to the plurality of reinforcing bar suspension bands.

Thereafter, a plurality of horizontal reinforcing bars are lifted at the same time by lifting a plurality of reinforcing bar hanging bands. The plurality of horizontal reinforcing bars thus lifted are gradually lowered, and stopped at a position orthogonal to each of the vertical reinforcing bars already standing on the ground.

In this state, each horizontal reinforcing bar is connected to each vertical reinforcing bar by wire.

Thereafter, by removing the reinforcing bar suspension band from the horizontal reinforcing bar, a lattice-shaped reinforcing bar unit is formed on the ground.

As described above, according to the present reinforcing bar suspension band,
Since multiple horizontal rebars can be stopped in the air against vertical rebars at once, there is no need to suspend horizontal rebars one by one against vertical rebars as in the conventional method.
It is possible to increase work efficiency.

The reinforcing bar fixing band is a band-like band, and the fastener comprises a metal fitting for stopping the band-like reinforcing bar fixing band. In this way, by using the band-shaped reinforcing bar fixing band and the stopper as the reinforcing bar fixing device, the horizontal reinforcing bar can be fixed to the band main body easily and in a short time.

As the reinforcing bar fixing device, in addition to the above, a combination of a hook member and a hook stopper member, or a hook and loop (usually a fastening member called "velcro" or "velcro") may be used. it can.

As described in the second aspect, a band suspending annular body can be provided at one or both ends in the longitudinal direction of the band main body.

The reinforcing bar fixing device can be attached to one or both of the front surface and the back surface of the band main body. By attaching the reinforcing bar fixing device to both the front surface and the back surface of the band main body, the reinforcing bar hanging band according to the present invention can be used reversibly, and the service life of the present reinforcing bar hanging band can be increased. As described above, when the present reinforcing bar hanging band is used reversibly, the band is hung on the crane at any of both ends by providing the band hanging annular members at both ends in the longitudinal direction of the band main body. Therefore, the convenience at the time of using the reinforcing bar suspension band can be improved.

When the reinforcing bar fixing device is provided on both the front and back surfaces of the band body, different coloring can be applied to the front and back surfaces of the band body. Thus, the front surface and the back surface of the band main body can be distinguished at a glance. Alternatively, instead of or along with the front and back of the band body,
Different colors may be applied to the reinforcing bar fixing device provided on the front surface of the band main body and the reinforcing bar fixing device provided on the back surface of the band main body. With this, the same effect can be obtained.
