Description of the Related Art Conventionally, when constructing an underground girder for a building, first, reinforcing bars and hoop reinforcements for reinforcing the underground girder are laid out, and then the formwork is arranged on both sides thereof, and the formwork on both sides is arranged. Formwork method of placing concrete in between is widely adopted, and plywood, wooden panels, metal panels, etc. are widely used for these forms. However, these molds must be dismantled and removed after the cast concrete has hardened.
A lot of labor and time are required for carrying out and cleaning up, and the construction cost of the underground beam is significantly increased.

L-shaped with a separator rod 3 for holding the space between the hoop muscle 20 and the lath net 21 and further with a loop portion 4C on the base 2 to which the upper end edge of the stretched lath net 21 can be fitted. Since the rod 4 is erected and fixed, not only the form lath net 21 can be supported and stretched at a predetermined distance from the hoop muscle 20, but also the upper end of the tension lath net 21 can be extended. The edge can be sandwiched in the loop portion 4C of the L-shaped rod 4, thereby preventing the situation where the upper edge of the lath net 21 spreads outward during concrete pouring, and the underground beam with a lateral width is adjusted. Can be built. In addition, it eliminates the need to remove the formwork after construction as in the past, and even if both sides of the underground girder are directly buried with earth and sand, it is significantly more economical than the method that requires formwork removal work.
