<p>PROBLEM TO BE SOLVED: To provide a reusable and user-friendly floating formwork device for forming bottom of an RC frame of upper base isolation layer capable of easily removing forms at a low cost.SOLUTION: The device 1 is used for cast-in-placing an RC frame 13 which is supported by a groundwork 10 via a seismic isolation support 12 to form the bottom face of the RC frame 13 so as to create a clearance 14 between the groundwork 10 and the RC frame 13. The device 1 includes: a supporting 2 which is disposed between neighboring seismic isolation supports 12,12 on the groundwork 10; and a bottom form 3 which is supported by the supporting 2 and forms the bottom face of the RC frame 13. Under the bottom form 3, plural inclined supports 4 are disposed in parallel, and the bottom face thereof is an inclined bottom face 4a inclined in an alignment direction. The supporting 2 has plural bottom form places 2a for placing the inclined supports 4 slidably in an inclined direction and is slidably connected to the bottom form 3 by a connecting member 7. The supporting 2 has form contact portions 2c, 2d which are in contact with the inner face of a form 15 for forming an elevation surface of the RC frame 13.</p> |
