, V'l m f= E% In order to achieve this object, the present invention connects and fixes the upper ends of parallel left and right weir plates with one interval between them using a connecting plate, and provides a jack on the connecting plate. Formwork installation In this construction method, concrete is cast between the left and right weir plates, and the formwork device is moved upward by the jacks by taking a reaction force from the reinforcing bars protruding upward, and the mold is discarded as the concrete hardens. A concrete structure is formed by forming a frame and pouring concrete between the cast forms.

A concrete hose is inserted between the upper ends of the weir plates (2) and concrete is poured between the weir plates (2). After the cast concrete has hardened, the jack (4) uses the reinforcing bars (5) erected in the hardened concrete as a reaction force to move the formwork device (1) upward as shown in FIG. After moving up to a predetermined height, concrete is poured between the weir plates (2) and (2) as described above, and anchor bolts (7) are installed in the hardened concrete waste forms (6) as shown in Figure 2.

By pouring concrete between these two tank formworks to form mass concrete structures such as dams, it is no longer necessary to attach and remove anchor bolts to set the formwork as in the past, and the work is simplified. Since everything is done inside, dangerous work is eliminated, and the moving set of the formwork device can be automated, which greatly improves work efficiency.
