PROBLEM TO BE SOLVED: To provide a method for constructing concrete-board driving type forms, in which a large-scale machine is not required and special technique and tool are not used and from which noises are hardly generated. SOLUTION: A concrete board has a groove 1 used in the case of a linear joining on the outsides of long sides, holes 2, 2a and 2b for a joining in which metal fittings 3 for the joining or pins 4 are inserted are formed to a periphery and the concrete board is assembled by using the pins and the metal fittings for the joining.
