(can also be set to shape). In addition, the length of the gantry 50 in the left and right direction is set to be shorter than the length of the floor part 11 on the first floor above ground side in the left and right direction (however, this is not limited to this. (The length may be set to be approximately the same as the length in the left-right direction.) Furthermore, the length of the gantry 50 in the front and back direction is set to be shorter than the length of the floor section 11 on the first floor side above ground in the front and back direction (however, this is not limited to this.

(The length may be set to be different from the length in the direction.) The above-mentioned "predetermined work" means, for example, first dismantling the edge portion of the floor 11 on the first floor above ground, then forming a hole in the foundation floor 14, and then demolishing the ground (not shown). This includes installing improved structures, etc.

（実施の形態の効果）
このように実施の形態によれば、複数の床部１０のうち最下方の床部１０以外の床部１０であって、建設重機ＣＥを設置する対象となる床部１０である対象床部に対して取外し可能に設置される構台５０であって、建設重機ＣＥを載置するための構台５０を備えるので、従来技術（コンクリートを増し打ちした床部にクレーンを設置する技術）に比べて、当該支持構造４０の設置作業及び撤去作業を簡易に行うことができ、当該支持構造４０の設置性及び撤去性を高めることが可能となる。 (Effects of embodiment)
As described above, according to the embodiment, the target floor 10 other than the lowest floor 10 among the plurality of floors 10 is the target floor 10 on which the heavy construction equipment CE is installed. Since the gantry 50 is removably installed on the other hand and includes the gantry 50 for placing the heavy construction equipment CE, compared to the conventional technology (technology of installing a crane on the floor where additional concrete is poured), The installation work and removal work of the support structure 40 can be easily performed, and the installation and removal properties of the support structure 40 can be improved.

また、構台５０よりも下方に設けられる補強柱部７０であって、対象床部又は構台５０を補強するための補強柱部７０を備えるので、対象床部又は構台５０を補強することができ、対象床部又は構台５０の設置安定性を高めることができる。 In addition, since the reinforcing column part 70 is provided below the gantry 50 and is for reinforcing the target floor part or the gantry 50, the target floor part or the gantry 50 can be reinforced.
