Further, the work floor provided so as to connect a plurality of pillars can function as an eave, and can contribute to, for example, rainwater countermeasures during construction of a building. From the above, the usability of the work floor can be improved as compared with the conventional technique (a technique of providing a corridor on the upper part of the building).

According to the work floor described in Appendix 2, since the work floor is integrally formed with a plurality of pillars, the work floor can be used at the same time as the construction of the plurality of pillars, and a plurality of work floors can be used. It becomes easier to use the work floor as a work scaffold during and after the construction of the building, as compared with the case where it is formed separately from the pillar portion of the building.

According to the work floor described in Appendix 3, the work floor was placed in the vicinity of the roof frame constituting the building, and the seismic isolation device was installed between the roof frame and the work floor. Since a stable installation surface of the seismic isolation device can be secured in the above, the seismic isolation device can be installed accurately.

According to the work floor described in Appendix 4, since the work floor is made of a concrete material, it is easy to construct the work floor according to the installation situation, and it is easy to improve the workability of the work floor.

According to the method of using the work floor described in Appendix 5, the work floor is used as a work scaffold for construction during the construction of the building and also as a work scaffold for maintenance after the construction of the building. It can also be used as a work scaffold and a work scaffold for maintenance. Therefore, since it is not necessary to separately provide a work scaffold for construction and a work scaffold for maintenance, it is possible to reduce the labor and installation cost for providing the work scaffold.
