As shown in FIG. 1, a barrier-free building 1 includes a support layer 3 provided with a seismic isolation device 2, a lower structure 4, an intermediate structure 5, and an upper structure which are sequentially provided on the support layer 3. 6 layers. In the present embodiment, the barrier-free building 1 may be any facility such as a hospital facility, a research facility or an office, but in the present embodiment, a hospital is taken as an example.

The support layer 3 of the barrier-free building 1 is
The seismic isolation structure is adopted. This is because the natural period of the barrier-free building 1 is lengthened by the seismic isolation structure to reduce the seismic force acting on the barrier-free building 1 and to absorb the vibration energy to ensure the safety of the barrier-free building 1. To secure. In the present embodiment, a seismic isolation device 2 including a laminated rubber 2a and an oil damper 2b is used at a position that supports the outer peripheral portion of the barrier-free building 1, and supports the central portion of the barrier-free building 1. At the position, seismic isolation device 2 using steel damper 2c
Is used. In addition, seismic isolation device 2 used for seismic isolation structure
The type is not limited to this, and any type may be used as long as it can reduce the seismic force acting on the barrier-free building 1 and absorb the vibration energy.

On the upper part of the support layer 3, there is arranged a lower structure 4 serving as an outpatient / medical ward in which examinations, medical treatments, etc. are performed.

Further, the horizontal piping 13, the ducts, the wirings and the like housed inside the double floor 16 are the same as the rigid frame structure 1 described above.
Since the girder 10 forming part 1 is provided with the opening 10a, it can be freely laid, energy can be supplied to a desired position on the floor, and the dry floor 17 is formed. In order to easily remove and change the energy supply position when the upper structure 6 is refurbished, it is possible to change the layout of the horizontal piping 13, ducts, wirings, etc., or perform maintenance.

Since there is no unevenness on the floor upper surface formed by such a dry floor 17, it is possible to realize a barrier-free space.

Further, since the composite slab 18 having a beamless plate is adopted on the lower surface of the double floor 16, it is possible to provide a plurality of blow-through spaces 21 at arbitrary positions.

Since the balcony 20 is provided on the entire outer peripheral portion of the upper structure 6, it is easy to illuminate and the amenities on the floor can be improved. Further, since the pillar 9 and the shaft 19 are configured to project to the side of the balcony 20, by providing a sufficient width of the balcony 20, a function of shielding sunlight from the window is provided and air conditioning at the window is not required. It is possible to reduce the use of a perimeter.
