A lift-up device for raising and lowering the temporary supports 5a... 5b... Relative to the temporary beam set 4; As shown in FIG. 2, the temporary beam set 4 is raised to a position on the fourth floor, for example, by using the one set 5a of the temporary columns as shown in FIG.

As a result, as shown in FIG. 2, the other pair of temporary columns 5b... Moves upward together with the temporary beam group 4, so that when the temporary beam group 4 is raised, there is a construction work space below. Are formed, a crane 8 for building a building for lifting members and the like are attached to the lower surface of the temporary beam set 4 via the rails 9, and the other set 5b of the temporary columns that have not been moved downward are mounted. The permanent post 10 on the ground is lifted by the building construction crane 8 into the permanent post construction space as shown in FIG. 2 formed between the lower end and the corresponding upper surface of the straight pillar 6, As shown in FIG.
The main support 10 is fixed on the upper part by welding.

Next, as a second step, the other set 5b of the temporary columns is moved downward by the lift-up device 7 relatively to the temporary beam set 4, as shown in FIG. The lower end of the other set 5b of the temporary columns is brought into contact with the tip of the permanent column 10 already fixed.

During the above operation, one set 5a... Of the temporary columns is raised by the lift-up device 7 to secure a space for the main columns below as shown in FIG. After that, the main support 10 is installed in this space by the crane 8 for building construction in the same manner as described above.
A beam 11 for the second floor is constructed below the floor. When the lift-up device 7 is further operated, the temporary beam group 4 rises to the height of the fourth floor as shown in FIG. 5 due to the reaction force.
Hereinafter, the first-stage operation and the second-stage operation are repeated to construct the beams up to the top floor while building the beams.

As a countermeasure against rain, it is preferable to provide a temporary cover 12 covering the construction work space.

FIG. 6 shows the state of the temporary shed 2 after the top floor is constructed. In the present invention, the temporary shed 2 is divided into a plurality of, for example, two parts 2a and 2b (edges), and the building is used for building. FIG. 7 shows the cut-away side 2a where the crane 8 is located.
As shown in the figure, the lift-up device 7 is used to move up along the temporary columns 5a..., 5b. A traveling crane 14 for dismantling, such as a building crane 8, is lifted from the ground, assembled and placed on the other 2 b of the temporary shed 2 that has not been raised, and the traveling crane 14 disassembles the building crane 8.
