To integrally construct a concrete structure with a floor slab 3 and precast members 6 by using legs 7 capable of reducing a construction term, facilitating the manufacturing of complicated members, presetting the upper face of the precast member 6 in a required height regardless of the structural condition of the floor slab 3, firmly connecting the floor slab 3, the legs 7 and the precast members 6 with concrete including reinforcements.
The precast members 6 manufactured in a factory are arranged in specified heights above the floor slab 3, joint rods 10 of the main reinforcements 11 projected from under faces of the precast members 6 and joint rods 8 of the main reinforcements 9 projected from the upper face of the floor slab 3 are connected to each other, concrete 13 is placed in a form 12 installed between the precast members 6 and the floor slab 3 to integrally joint the upper face of the floor slab 3 and the lower faces of the precast members 6. Thereby, members with complicated shapes are manufactured in a factory and the heights are adjusted by the legs 7 between the floor slab 3 and the precast members 6.
