[0002]

2. 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 over 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 that it is necessary to transport it in a stack, which is inconvenient. In addition, the ceiling and both legs must be integrally formed by the same wire, for example, by welding, and this has been a neck, which has been likely to increase the cost of members.

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.
