PROBLEM TO BE SOLVED: To provide a structure constructible by a simultaneous advance by constituting a building body and a rampway by being made of precast PC, and eliminating the necessity of maintenance and repair by imparting super-durability by being formed as a base-isolation structure.SOLUTION: A PC column 3 and a PC beam 4a are formed of precast concrete, and a column-beam joining part is constituted by being integrally PC-press-fitted/joined by tensioning-fixing a PC steel material. The beam receiving jaw is projectingly formed on a PC column 3 in a height adjusted to a predetermined gradient, and a beam on the inner-outer peripheral edge side of the PC beam 4a is formed in a curve shape of becoming a concentric circle with a circular lamp in the longitudinal direction. Thus, since a rampway building structure 2 can construct a precast member similar to a building body 1 at a job side by a PC press-fitting joint method simultaneously with the building body 1, workability can be largely improved since cargo handling work can be directly executed by riding a vehicle in the respective floors even in construction time.SELECTED DRAWING: Figure 3 |
