The standard floor 1 referred to in the present invention usually means the first floor above the ground, but in some cases, it may be the lowest floor underground or a super mega truss pre-built on the ground. Therefore, it should be understood that, in parallel with the construction of the above-mentioned ground portion, the construction of the standard floor or the so-called underground structure below it is generally accepted. Since the driving floor 3 is always used as a roof substitute for a construction workshop after that, it is subjected to some rain curing. In some cases, on the driving floor 3, an outer curing film may be hung on the outer periphery of the building. The driving floor 3 is also configured as a sky factory that doubles as a construction office and an assembly factory necessary for the subsequent construction of each floor of the building. The overhead traveling type circle crane 4 referred to in the present invention refers to, for example, Japanese Patent Application No. 2-152467 and Japanese Patent Application No. 2-152468 specification and drawings, in which the boom horizontally swings and horizontally expands or contracts or moves. A crane that can be used for transporting and assembling frame parts, equipment, and finishing units by means of a lift attached to the boom. The circle crane 4 is installed by half-up by a height corresponding to the height of the worker after the construction of the drive floor 3 is completed on the reference floor 1. After that, the driving floor 3 is located at a position slightly above the floor height of at least one floor (for example, about 4 to 5 m above the floor of the reference floor 1) on the assumption that the floor structure 5 ₁ above the reference floor 1 is constructed. ), And temporarily fixed to the main pillar 2 at that position and placed.

Steel frame pillars at this stage,
FIG. 2B shows an example of the structure of beams and floors. In addition, since the main installation column 2 is added to the upper part, it is possible to use a long column alone having two or three layers as one node, which can reduce the number of joints and save the steel frame construction cost.

FIG. 1E shows that, by raising the driving floor 3, the second-floor floor structure 5 ₁ which has already been constructed is raised to the normal position on the second floor together with the third-floor floor structure 5 ₂ constructed on it. The floor structure 5 ₁ on the second floor shows the stage where it is attached and fixed to the main installation column 2. Therefore, the time required to raise the two floor structures 5 ₁ and 5 ₂ can be shortened. The ascending system at this time is shown in FIGS. 2C and 2D. That is, ascending frames 8 each having a substantially square shape are installed diagonally around the main installation columns 2 on the steel beams 10 arranged in four directions around the main installation columns 2. The ascending operation is performed by a structure in which a cable 7 (a jack in case of jacking up) is connected to the position.

FIG. 1F shows a stage in which the floor structure 5 ₁ on the second floor is left and the floor structure 5 ₂ on the third floor, which has already been constructed, is half-up. Fig. 1G shows that the slab concrete is placed when the floor structure 5 ₂ on the third floor is made of steel while the half-up stage is being used, and the floor structure 5 ₁ on the second floor is fireproof coated, ducted, etc. 2
