To solve the problem that a supporter for conventional concrete forms is composed of a large number of components such as vertical and horizontal batters, supports, bracings, metal fittings connecting these members or the like, and require extremely troublesome works such as a management, a carrying-in to a site, an assembly, a mounting and fixing, a removal after the curing of concrete or the like.

The supporter for the concrete forms are composed of a horizontal leg 3, in which one end is connected to the lower section of the concrete forms 1, and the support 4, in which one end is connected to the upper section of the concrete forms 1 and the other end is connected to a seat board 5 fixed onto a floor face and which is arranged obliquely, the other end of the horizontal leg 3 is connected to the lower section of the support 4 and the support 4 is adjusted by interposing a turnbuckle 43.
