Summary:PROBLEM TO BE SOLVED: To prevent deterioration of structure characteristic by normal quality control by sequentially applying adding driving operation by means of drive relaying part arranged in the inner surface direction so that the drive relaying parts continously arranged in the inner surface direction of underground outer wall or a projecting part in the outer surface direction, etc., are connected. SOLUTION: A first drive part 1 is formed by placing connect by use of a drive relaying form 1' having a protrusion 1a or a recess continously extending in the inner surface direction of underground outer wall so as to transmit in-surface shearing force to a lower part of underground 1st floor, and a projection 1b or recess connecting the projecton 1a or the above recess extending in the outer surface of the underground outer wall, at a bottom form of a first drive part 1 constructing perpendicularly suspended concrete at the underground 1st floor. Then, after the construction of underground 1st floor slab 3, the form 1' is disassembled and a post drive part 4 is constructed on the slab 3 to form a drive relaying part. The drive relay form 1' is used to apply addition drive of structure downward in order. Accordingly, even if sinking is generated after the placement of concrete, no gap is generated between the first drive part 1 and the post drive part 4.
