Figures 10 to 12 show the condition of roads and reinforcing bars to be built. For roads of width W (eg 8.5m), there is reinforced concrete of thickness T (eg 250mm) from the roadbed to the top plate. It is cast. The bar arrangement is horizontal bar A (eg 16φ x 8.5m)
Pitch P1 (eg 200 mm), vertical stripe B (eg 16φ × 12
m) pitch P2 (for example 250 mm), lap length 1 of the vertical stripe B
Is taken at 2P1 (ie 400mm for example). Also,
The spacer 40 has a horizontal pitch equal to 4P2 and a vertical pitch equal to 2P1, and the reinforcing bar height t is approximately 70% of the concrete thickness T. On both sides of this road,
Rails 41, 41 are laid, and the traveling carriage 2 travels on the rails 41, 41.

At the time of work, the horizontal streak A and the vertical streak B, which have been bound in advance, are arranged at appropriate places on the roadbed.

The traveling carriage 2 is stopped, the bundle of the horizontal stripes A is drawn onto the frame 3 by the horizontal stripe drawing lift 7, and the bundle of the vertical stripes B is drawn into the work table 5 by the vertical stripe drawing lift. Then, the bundle of the horizontal stripes A is separated, and the bundle of the vertical stripes B is separated by manually placing the bundle of the horizontal stripes A on the receiving metal fitting of the horizontal stripe feed conveyer 9 and sending it out.
6 and put it on the vertical streak feed roller 10 and send it out. Then, the lap portion of the horizontal bar A on the horizontal bar feeder conveyor 9 which is stationary at the automatic binding machine 11 and the vertical bar B superposed on the horizontal bar A is moved by the automatic binding machine 11 with the binding wire 16 in the lateral direction. From one example (left side in the illustrated example), the other side is automatically bound. After the binding is completed, the spacer 40 is attached as shown in FIG. Then, the horizontal bar feed conveyor 9 is operated by the length of the automatic binding machine 11 in the vertical direction, and the traveling carriage 2 is run to bind the reinforcing bar with the spacers 40 installed on the roadbed. After that, the same procedure is repeated to lay the reinforcing bar.

At this time, since the lap length 1 of the reinforcing bar B is set to be twice the pitch P1 of the transverse bar A, it is bound by at least two lap portions, but it is not limited to this, and the lap length 1 can be shortened. May or may not be tied together with the vertical muscles,
Alternatively, the lap length 1 may be eliminated and the ends of the vertical stripes B may be welded to each other. Further, instead of intermittently operating the horizontal bar feed conveyor 9 and running the traveling carriage 2 to lay the reinforcing bars, automatic binding is continuously performed in the vertical direction, and the horizontal bar feed conveyor 9 is continuously driven to run. The trolley | bogie 2 can be made to run and the efficiency of vertical bar installation can also be improved.

[Summary] As described above, according to the present invention, the horizontal and vertical stripes are drawn into the traveling carriage, fed out, and automatically bundled to be laid on the roadbed from the traveling carriage to reduce the artificial and improve the reinforcement accuracy. The construction cost can be reduced and the construction period can be shortened.
