In this case, four or two of the pillars 1 of the present example are provided with a gutter receiving hole 2 at an upper end thereof and a discharge hole 3 at a lower end thereof, and communicate with them. An omitted drainage channel is provided, and a detachable cap 4 is fitted to each of the gutter receiving hole 2 and the drainage hole 3 and closed.

On the other hand, the floor-mounted base 10 comprises a base frame 11 having front and rear and left and right beam members 12 and a beam member 14 fixed between them, and a front and rear or left and right facing beam member 12. On the other hand, one side of the girder member 12 is higher,
A floor member 15 is disposed on the base frame 11 by supporting the both ends so that the other girder member 12 is lower, and supporting the intermediate portion with the beam member 14 so as to be inclined. , In this example, the floor material 1
5 is inclined to the base frame 11 by forming a plurality of floor material mounting portions 13 vertically on the opposing surface of the opposing girder material 12 and forming a plurality of upper and lower floor material mounting portions between the opposing girder materials 12. 13, both end portions of the floor member 1 are placed and supported, and at least the upper end position of the beam member 14 installed in parallel with the opposing girder member 12 is arranged so as to form a vertical step.
The intermediate portion of the floor member 15 is placed on the upper end of the step-shaped girder member 12 and is supported and supported.

That is, the girder member 12 and the beam member 14 forming the base frame 11 are also made of a thick plate or a thick frame member having a hollow cross section of an extruded aluminum member in this embodiment. They are relatively short, and the left and right are relatively long.
The beam member 14 is shorter than the beam member 12 which is also configured to be relatively short and relatively long.

At this time, the left and right girder members 12 are provided with a plurality of floor material placing portions 13 on the upper and lower sides. However, the aluminum extruded material as the girder member having sufficient strength becomes complicated and the yield is reduced. In order to avoid this, this is formed by the girder main body and a separating member for retrofitting and fixing to the lower part on the opposite surface side, and the plurality of, in this example, a pair of upper and lower flooring mounting portions 13 are connected to the girder main body. And the upper surface of the separation member fixed to the girder material body.

The base frame 11 connects the girder members 12, the girder member 12 and the beam members 14, and the connection between the girder members 14 by using an assembling fitting 15 having an appropriate shape such as an L-shape or a U-shape.
