2, and the base member 53 is attached to the four corners of the base material 50 with screws 54.

However, in order to obtain the strength required for the base member 53, it is necessary to increase the number of lattice-like plate parts 52 and increase the thickness of each part, which makes the structure complex and increases the weight. do. Moreover, although the sheet-like base material 50 and the base member 53 can be separated, the volume of the base member 53 itself is large, so it tends to be bulky during storage or transportation. Furthermore, since a large number of base members 53 must be screwed one by one to the sheet-like base material 50, a lot of effort is required to attach them.

[Problem that the invention attempts to solve]

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to simplify and lighten the structure and facilitate assembly while ensuring sufficient strength required for a base member. The purpose of the present invention is to enable storage, transportation, etc. to be carried out advantageously in terms of space.

[Means for solving problems]

The floor support according to the present invention includes a base material laid on a floor base, an engaging part for positioning that can be freely engaged with and detached from the engaging part of the base material, and at least a lower part of the base material, which has a mounting surface for the floor plate. It consists of a cylindrical base member that opens at the bottom, and the base member is configured such that the diameter becomes larger toward the lower end thereof, so that the operation and effect are as follows. It is as follows.

[Effect]

The base member has a cylindrical shape with a downward opening, and has a tertiary surface structure in which the diameter increases toward the lower end, so even though the base member is thinner, it can act through the flooring material. It is possible to ensure sufficient strength to withstand compression, vibration, etc. Moreover, since a plurality of these base members can be stacked in multiple stages in a fitted state, the space occupied by the base members during storage, transportation, etc. can be made as small as possible.
Moreover, the base material and the base member can be easily positioned by engagement.

[Effect of idea]

Therefore, the base member can be constructed with sufficient strength to withstand compression, vibration, etc., while simplifying the structure and reducing the weight compared to the conventional one. Moreover, the base material and base member can be assembled quickly on site.
This was not only easy to do, but also made it possible to store and transport the support stand compactly.
