[Industrial applications]

 The present invention relates to a self-supporting rebar wire mesh used in civil engineering and construction.

[0002]

[Prior art]

 Conventionally, as shown in Fig. 11, the inner wall construction of the tunnel has been performed by the following process by the NATM method. First, after excavating to a predetermined size, after the excavation is completed, the support structure 91 is formed using H-shaped steel or the like, and the primary concrete 92 is applied to the extent that the gap of the support structure 91 is filled. After the primary concrete 92 is solidified, a waterproof sheet 94 is adhered to the inner side of the primary concrete 92 for the purpose of protecting the lining concrete 93 from groundwater or forming a separation layer between the ground and the structure. Let me install it. After the attachment of the waterproof sheet 94, the horizontal bars 95 and the vertical bars 96 curved in a predetermined shape are arranged vertically and horizontally, and the intersections are fixed by welding or binding to form an integral reinforcing wire mesh. However, the shape of the integrally reinforced wire mesh will be distorted by its own weight. For this reason, a hole is made in the waterproof sheet 94, and an integral rebar wire mesh is attached and fixed to the supporting member 91 via a supporting member 97. When the fixing was completed, a lining concrete form 98 was provided so as to be separated from the integral rebar wire mesh for a predetermined period, and the concrete was poured and solidified to form the inner wall of the tunnel.

[Problems to be solved by the device]

 However, it is very troublesome for the worker to arrange the vertical bars 96 and the horizontal bars 95 one by one on the site, and when the one-piece reinforced wire mesh is fixed to the supporting work by the support member, the waterproof sheet is used. There is a problem that the effect of the waterproof sheet 94 is halved because holes are made in the 94. Furthermore, working for a long time in a tunnel with extremely high temperature and humidity has been a big problem for workers. In addition, it may be possible to divide it into slices at the factory in advance, manufacture them, and then attach them at the site, but due to restrictions such as the Road Traffic Act, there was a problem that they had to be kept within about 3 m in width × 10 m in length. .

As shown in FIG. 2, a bar-shaped upper end bar 24 made of iron is welded to a bent part 26 on one side of a corrugated lattice bar 25 made of iron to be fixed thereto. After that, the upper end streak 24 is bent into a predetermined shape by a bending machine. When the bending process is completed, the bending portion 27 on the other side of the wavy lattice reinforcement 25 is welded to the iron rod-shaped lower end reinforcement 28 that is curved with the same curvature as the upper end reinforcement 24, so that the reinforcing member 18 of the truss structure is formed.
