Zusammenfassung:	PURPOSE:To firmly connect new and old concrete to each other, surely improve the strength of the placing joint with a simple constructing method, and suppress the breezing in the placing joint. CONSTITUTION:A sheet material 3 with projections 3a in which air is sealed is stuck to the inner surface 2a of a placing joint form 2 for placing old concrete 1, and concrete is then placed therein. When the placing joint form 2 and the sheet material 3 are removed, recessed parts 1b and flat parts 1c are formed on a vertical placing joint 1a, and when new concrete 4 is placed, the new and old concrete form a mechanically engaged joint part. The adhering area of the joint part is enlarged, and the bending tensile strength of the member is also increased. By forming such irregularities on the vertical placing joint 1a, the moisture ascending on the placing joint can be reserved to prevent reduction in strength of concrete.
