Abstract

PROBLEM TO BE SOLVED: To improve the earthquake resistance and make the work more efficient by surrounding a core column double with inner and outer rigid-frames, forming a floor in a prescribed floor, temporarily setting a roof thereon, making a floor slab for a lower floor on this floor, and successively setting it form the upper part. SOLUTION: A core column 1 having concrete filled steel pipe structure is stood in a position corresponding to the center of a multistoried building, and a core 3 consisting of a five-storied tower rigid-fame (inside rigid-frame) 2 is stood around it. A hut beam 4 having a shade-like cover 4a is temporarily set on the upper end of the core 3, a work scaffold 5 is suspended from the hut beam 4, and a corridor rigid-frame (outside rigid-frame) 6 is constructed in order from the lower part. A super-rigid-frame 9 forming a work floor is formed in a prescribed floor (for example, every 10 floors) in this manner, and a floor slab 10 for the other floor is formed thereon and successively mounted from the lower floor, whereby the work can be progressed without being influenced by the weather. Accordingly, a multistoried building excellent in earthquake resistance can be provided in a short period at a low cost.

The construction method of this embodiment is used for construction of a high-rise building. At the time of implementation,
At a position corresponding to the center of the high-rise building, a core 3 including a center pillar 1 and a five-storied ramen (inner ramen) 2 is erected (Step A). As can be seen from FIG. 2, the five-storied ramen 2 has a square cross section formed by connecting reinforced concrete columns 2a by reinforced concrete beams 2b so as to surround the core column 1 having a concrete-filled steel pipe structure. Here, the self-climbing method was used for erecting the core 3.

After the scaffold 5 is installed as described above, the above-described corridor ramen 6 is successively constructed from below using the scaffold 5 as appropriate (step D). However, here, the step D is started from a stage before the installation of the scaffold 5 is completed. In other words, in this embodiment, in order to shorten the construction period, work that can be performed without using the scaffold 5 is started from a stage before the installation of the scaffold 5 is completed. In addition, as can be seen from FIG. 3 showing a cross section of a portion where the girders 7 and 8 are not provided, the corridor ramen 6 is reinforced concrete columns 6a so as to surround the five-storied pagoda ramen 2 constructed earlier.
Are connected by a reinforced concrete beam 6b and have an octagonal cross section.

When the step D is completed, in the five-storied ramen 2 forming the core 3, the portion located on the [10 × N (N is a natural number) +1] floor and the corridor ramen 6 have the same [10 × N ( N is a natural number) +1], and a floor is formed (step E). More specifically, in the five-story pagoda ramen 2, the 11th floor, 21
As shown in FIG. 2, the portions located on the floors, the 31st floor, etc., and the portions located on the 11th, 21st, 31st floors, etc. in the corridor ramen 6 are connected by girders 7. At the same height, the pillar 1 and the five-storied ramen 2 are connected by the girders 8. And this girder 7,
After placing the floor material on the floor, concrete is cast and the floor on which the floor slabs to be placed on other floors can be manufactured (main floor)
To form Thus, [10 × N (N is a natural number)
On the +1] floor, a super ramen 9 is constructed.

When the super ramen 9 is obtained as described above, nine floor slabs 10 are sequentially manufactured from the lower floor using the super ramen 9 (step F). At the end of the floor slab 10, a receiving metal 10a is provided so as to be able to protrude and retract as shown in FIG. Once the production of the floor slabs 10 is completed, they are once raised up to the height of 9 floors. That is, the entire floor slab 10 is raised so that the uppermost floor slab 10 is located on the [10 × N (N is a natural number)] floor. However, as shown in FIG. 4, this operation is performed using a jack 11 previously installed in each super ramen 9 and a suspension cable 12 drawn out from it.

Thereafter, the floor slabs 10 are attached to the corridor ramen 6 on the corresponding floor in order from the one located above while lowering the floor slab 10 stepwise (step G). However, in practice, this G step is not started after raising the floor slab 10 formed on all the super ramen 9 in order to shorten the construction period similarly to the above D step. The steps are performed sequentially from the section where the process is completed. FIG. 4 shows a state where the uppermost floor slab 10 of a certain section has been attached. By the way, in the state where the installation of the top floor slab 10 is completed, the floor slab 10 is fixed to the corridor ramen 6 by the above-described receiving hardware 10a, and then the reinforcing bar is provided thereon, and the concrete 13 is further poured.

When the fixing of the floor slab 10 is completed in this way, an outer wall is formed using a curtain wall or the like sequentially from the lower floor, and the remaining construction work is performed to complete a high-rise building. As described above, in the present embodiment, the framework of the high-rise building is composed of the pillar 1, the five-storied ramen 2 surrounding the pillar 1, and the corridor ramen 6 surrounding the five-storied ramen 2. That is, the frame of the high-rise building was formed by combining the double tube composed of the five-storied pagoda ramen 2 and the corridor ramen 6 with the mandrel 1. Therefore, like a five-storied pagoda,
Sufficient proof strength and toughness are secured, and even if the ground shakes greatly due to the earthquake, it can flexibly cope with it. Therefore, the high-rise building obtained by the construction method according to the present embodiment exhibits remarkably excellent earthquake resistance.

In this embodiment, a super ramen 9 serving as a working floor is formed every tenth floor, and a floor slab 10 arranged on another floor is manufactured on the super ramen 9. Then, after the manufactured floor slab 10 is once raised, the floor slab 10 is attached to a specified position in order from the upper one while being lowered. For this reason, compared with the case where floors are constructed in order from the bottom, work efficiency is greatly improved, and the construction period can be shortened and the construction cost can be reduced. Further, since the temporary beam 4 installed at the upper end of the core 3 is provided with the cap-shaped cover 4a, it is possible to cope with all weather, and the construction can proceed as scheduled without being affected by the weather.
