PROBLEM TO BE SOLVED: To secure an integral connection of boards. SOLUTION: A joint board 12, a backing plate 14, and anchor bolts 16 are used for connection of form boards 10. The joint board 12 is a flat plate formed in a beltlike shape with a specified width, and extended over the whole length of the rear face side along the vertical and horizontal joint parts of the permanent form board 10 so as to be set astride adjacent permanent form boards 10 and installed with an adhesive 18 interposed. The backing plate 14 has tap holes 20 and is stuck to the rear face side of the joint board 12 through the adhesive 18. The anchor bolt 16 is screwed into the tap hole 20 through a mounting hole 11 and a through hole 13 from the surface side of the permanent form board 10 in the condition that the joint board 12 and the backing plate 14 are attached to the rear face side of the permanent form board 10, thereafter, the anchor bolt is embedded into concrete placed afterward.
