DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates primarily to a stage-type floor support device installed to provide an accent within a large space of a building.

Conventional technology A stage-shaped floating floor is installed in a large space of a building, and -1
The idea is to have two accents. On the other hand, in general, for a stage-type floor, support columns are usually erected from below, and the floor is supported by the columns.

Problems to be Solved by the Invention As mentioned above, when a floor is installed simply as an accent, if the floor and its supporting device become large-scale, the whole system becomes heavy and there is a risk of having the opposite effect. However, in the conventional structure described above, columns are built under the floating floor to support it, which has the disadvantage that the column becomes heavy as the column occupies a position under the floor. occupies the space under the floating floor, resulting in the inconvenience of narrowing the space and hindering its use.

The present invention was made with the aim of eliminating such conventional drawbacks.

Means for Solving the Problems In order to solve the above-mentioned taMA, in this invention, the upper end of the hanging column is fixed to the side surface of the beam constituting the structure, and this hanging column is suspended, and the lower end of the hanging column is also connected to the floor. The floor frame is fixed to each other to support the floor frame.

Effect: In the configuration of the present invention described above, the upper end of the hanging column is fixed to the side surface of the beam that constitutes the structure, and the lower end of the hanging column supports the floor. The overall structure is less heavy than those that support the floor, and it does not narrow the space below.
