摘要： PROBLEM TO BE SOLVED: To provide an embedded form with high durability which is constituted as a lightweight and low-profile type by making the used amount of a material small, can be easily manufactured and constructed, and can make a span long.
SOLUTION: A rib 1 of the embedded form 11 and a slab 3 thereof are separately manufactured. In the rib 1, a part joined to the slab 3 has a curved surface 5. In the formation of the embedded form 11, the rib 1 and the slab 3 are joined to each other by joining tools 13 while a top surface 7 of the slab 3 is positioned along the curved surface 5 of the rib 1. The joining tools 13 are arranged at a predetermined space in the axial direction of the embedded form 11. The shape of the curved surface 5 is set so that the rib 1 and the slab 3 can generate initial deflection (initial stress) when they are joined to each other. In the embedded form 11, compressive stress is pre-generated on the undersurface 9 of the slab 3 in a state of joining the rib 1 and the slab 3 to each other, so that tensile stress generated on the undersurface 9 of the slab 3 in the placing of post-cast concrete 27 can be reduced.
