PURPOSE:To eliminate the needs for the separation of both sheathing boards by a method in which a prefabricated sheathing board for surface side and a metal net sheathing board for the back side are erectely set at a fixed interval by means of a separator, formworks are assembled for retaining wall, etc., and concrete is placed between the formworks. CONSTITUTION:A formwork structure for a rentaining wall, etc., consists of a surface sheathing board 1, a metal net sheathing board 2 at a given interval in the face of the board 1, a waling 6 to hold both the sheathing boards 1, and 2 at a fixed interval, and a structural brace 10 and a vertical stud 11 on the metal net sheathing board 2l side. The sheathing board 1 is a fabricated on serving as a finishing material for the outer wall of concrete structure, and the sheathing board 2 uses a metal lath with ribs. Concrete is placed between the formworks constructed and hardened, and the braces 10 and studs 11 are removed to construct a concrete structure. A retaining wall, etc., can thus be constructed without the needs for separation of the sheathing boards. |
