(E) and FIG. 9 (F) to (H) are side views showing the construction method of the present invention using the above-mentioned equipment in the order of steps. Hereinafter, the steps of the construction method according to the present invention will be described with reference to FIGS. First, as shown in FIG. 7 (A), a pedestal 30 is temporarily assembled on the ground with the basement portion of the main pillar 4 of the building 1 or the like to be constructed being built, and the top floor structure is placed on the pedestal 30. , Or a roof floor 10 as shown in FIGS. 1 and 2 having a temporary structure as a whole is assembled by assembling in blocks. The lifting drive device 5 is mounted on the roof floor 10, and the movable columns A and B are inserted into the lifting drive device 5 and the lower ends thereof are fitted to the upper ends of the main columns 4 to be combined with the elevator drive device 5, Assemble a control room on the 10th floor and install a prime mover and other necessary equipment. As shown in FIG. 3B, the movable support pillar B is slightly raised to the height of the roof floor 10 by the elevating / lowering drive device 5, and then the movable support pillar A is jacked up by about the second floor height with the movable support pillar A as a fulcrum. After stopping and after mounting the overhead crane 6 and the shielding enclosure 7 on the roof floor 10 under this state, the overhead crane 6 is used to install the main installation pillar member 4a (1 (Floor height). 7 to 9, the shielding surrounding wall 7 is not shown. As shown in FIG. 6C, after the movable support pillar B is lowered and fitted on the main installation pillar 4, the movable support pillar A is raised to and held at the height of the roof floor 10, and the overhead crane 6 is used. Then, the main pillar member 4a (for the height of the second floor) corresponding to the movable strut A is installed, and the beam members 2a to 3a on the second floor are installed between the main pillars 4 that have been installed and up to the second floor. Work such as wall driving, floor deck reinforcement and concrete driving.

Next, as shown in FIG. 8 (D), after the movable support pillar A is lowered and fitted on the main installation pillar 4, the movable support pillar B is raised to the height of the roof floor 10 and held. Then, the overhead crane 6 is used to build the main installation pillar member 4a (for the height of the second floor) corresponding to the movable support pillar A, and the beam members 2a to 3a on the third floor are provided between the installed main installation pillars 4a. Installation of, and wall driving up to the third floor, floor deck reinforcement and concrete driving. As shown in (E) of the figure, after the movable support pillar B is lowered again and fitted on the main installation pillar 4, the movable support pillar A is raised to and held at the height of the roof floor 10, and the crane 6 is fixed. The main pillar member 4a (for the height of the second floor) corresponding to the movable pillar A is built by using it, and the beam members 2a to 3a on the fourth floor are mounted between the main pillars 4 that have been built up to the fourth floor. Work such as wall striking, floor deck reinforcement and concrete striking, and in this process, the exterior PC plate 31 on the outer wall of the building up to the third floor is installed. Similarly, the rising of the roof floor 10 by the movable columns A and B and the building work similar to the process (E) are repeated alternately to proceed with the construction of the upper floor.

Further, as shown in FIG. 9 (F), when the building construction reaches the top floor, for example, the 18th floor, the roof floor 1
When 0 also serves as the top floor structure of the building 1, the construction of the main pillar 4 and other construction work are stopped up to the 18th floor, and the movable columns A and B are placed on the main column 4 respectively. The movable pedestals A and B corresponding to the rooftop penthouse 33 (see (G)) are fixed to the main pedestal, and a decorative plate or the like is attached to the rooftop 1
Installed a jib crane 32 on the rooftop of 0 and installed an overhead crane 6
After dismantling and removing, the roof floor 10 is lowered to the lower part of the movable columns A and B. As shown in FIG.
By 2, the lifting drive device 5, the equipment such as the prime mover, the control room, etc. in the roof floor 10, the removal of the reinforcements, the cutting and removal of the movable columns A, B and the roof floor 10 except the roof penthouse 33 To do. Finally, as shown in FIG. 3H, after finishing the rooftop and the penthouse 33, the jib crane 32 is dismantled and removed to complete the building construction.

[0014]

In the above process, when a temporary structure is used for the entire roof floor 10, the movable columns A and B on the outer periphery of the building are used at the intersections in the process of FIG. 8 (F). The roof pillar 10 rises and only the central part of the building is the main pillar 4 of the height of the second floor.
After constructing the beams, floors, and walls for two layers, the overhead crane 6 is dismantled and removed, the jib crane 32 is installed on the roof floor 10, and the following (G) to (H) By performing the steps, the building can be smoothly completed without the need for extra makeup work caused by the size mismatch between the main pillar 4 and the movable pillars A and B. Under each of the above-mentioned steps, the roof floor 10 is always stably supported alternately by the movable columns A and B arranged in a distributed manner over the entire plane of the building, and at the same time, the roof floor 1 is always safely maintained in a stable state.
It is possible to perform a zero jack up operation.
Furthermore, using the overhead crane 6 on the construction floor 8,
In the construction work of columns, beams, floors, and walls, half of the movable pillars distributed over a wide area of the building to be built are always on the roof floor 1
Since it is possible to work in the space of the large building floor 8 that has been raised to 0 height, the overhead crane 6 can move freely in a wide range to perform construction, and the construction on the building floor 8 By advancing the construction work by half unit of each floor area every time the roof floor 10 is raised, it is possible to obtain an effect of greatly reducing the work time. Note that energy saving and cost reduction can be achieved by using the entire roof floor as a temporary structure.

In short, according to the first aspect of the present invention, the roof floor of the high-rise structure to be constructed is provided with a large number of movable columns that can be moved up and down by a drive unit, and the movable columns are installed on the main column. In the method of stacking and constructing high-rise structures under the roof floor by the vertical and horizontal transfer systems provided on the roof floor while raising the roof floor by exchanging upward as a fulcrum, the movable pillars provided on the roof floor are constructed. It is divided into two groups A and B, which are distributed throughout, and the movable floor group A on one side supports the roof floor, and the movable pole group B on the other side is raised, and a high-rise structure is formed in the space below the building floor. By repeating the process of constructing and constructing the upper part of the object alternately, there is no restriction on the operating range of the overhead traveling type transport device on the construction floor, and it is economical all-weather to shorten the construction work time and construction period. Since obtaining a construction method for high-rise structures, the present invention is extremely useful industrially.

According to the invention of claim 2, claim 1
In addition to the effect of the above, the present invention is extremely useful industrially because energy saving and cost reduction can be achieved by a lightweight and low cost roof floor structure.
