Description of the Related Art Reinforcing bars are arranged in a grid pattern on a slope, and the mortar or concrete (hereinafter, referred to as mortar) is large enough to blow the reinforcing bars without hindrance. A grid frame is formed by integrally forming a ceiling having a ceiling portion and both side legs extending downward from the ceiling portion with the same wire to form a grid frame, and mortar is placed on the grid frame. In a simple method called the soil cleat method (for example, see Japanese Patent Publication No. 4-41724, Japanese Patent Publication No. 5-7492, and Japanese Patent Publication No. 5-20528), the above-mentioned mold is used. Since the frame is formed in a trapezoidal shape when viewed from the front, the mold cannot be folded and transported, so it is necessary to transport it in a stack, which is inconvenient. Further, the ceiling and both side legs have to be integrally formed by the same wire, for example, by welding, and this has been a bottleneck, which has tended to increase the cost of members.

で、コスト高となっていた。Further, even when a legal frame is formed using a pedestal for holding a reinforcing bar at an appropriate position so as to ensure an accurate sprayed cross-sectional shape, it is necessary to stack the pedestal and transport it, which is inconvenient. Moreover, since the pedestal is formed by welding, the cost is high.

If the length is long, the handling is inconvenient at the expense of less labor for connection. Therefore, an appropriate length may be used as needed. In addition, the intersection G of the frame A is generally formed by connecting in an abutting state.

After the reticulated body 5 is stretched thereon, four rebars 6 are arranged on the reticulated body 5 so as to be positioned at the four corners of the hoop rebar 4, and are arranged in a state of floating in a lattice shape. A frame A is laid so as to cover 6. In this case, the space holding member 9 and the opening prevention member 1 are provided at places deemed necessary after the laying of the frame A.
1 is set. That is, the plurality of spacing members 9 arranged vertically connect one wire netting frame 1a and the vertical portion 4a of the hoop streak 4 arranged adjacent to the wire netting frame 1a. Are connected to the other wire mesh form 1b and the vertical portion 4b of the hoop streak 4 arranged adjacent to the wire mesh form 1b by a plurality of spacing members 9 arranged in
Further, the lower part of the wire mesh forms 1a, 1b
An opening prevention member 11 is erected between b. Thus, the wire mesh forms 1a, 1b can be prevented from being opened, and the wire mesh forms 1
The distance m between a, 1b and the reinforcing bar 6 can be maintained.

5 is formed. In particular, even if the beam to be formed is a beam corresponding to the horizontal frame portion 13 and having a very large cross-sectional area, the weight of the mortar or concrete is reduced by the spacing member 9 and the opening prevention member 11. Wire mesh form 1 by spraying pressure
The mortar or concrete can be laid in a prescribed place where the sill 15 is formed by a single spraying without opening the a and 1b or bending the beam downward.
