DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a building by a construction apparatus, and more particularly to an assembling stage disposed over a building under construction, and a supporting and lower end portion of the assembling stage. And a supporting column for obtaining a supporting reaction force from an existing structure located below an assembling work stage.

[0002]

2. Description of the Related Art In recent years, a building construction method using a construction apparatus has been adopted as a means for solving a shortage of labor in construction work of a high-rise building. This construction device is equipped with a system for performing construction work such as lifting and assembling of structural materials and placing concrete, etc., by organically linking overhead traveling cranes and various work robots, etc. Thus, the construction work can be automated and labor can be saved.

[0003] That is, this construction apparatus is mainly provided so as to cover the upper part of a building under construction, and has an assembly work stage provided with facilities such as the overhead traveling crane and various work robots. It consists of supporting columns that support the assembling stage by obtaining a supporting reaction force from the existing structure located below the working stage. The climbing device provided at the lower end of the supporting column sequentially raises the assembling stage. The building will be constructed further above the existing structure while moving to.

On the other hand, in the case where a building is constructed by the above-mentioned construction equipment, if the floor area of the building is large, the supporting column supporting the assembling work stage has a large burden against horizontal force such as seismic force. The support columns must be specially strengthened, and labor, materials, used machines, and the like are concentrated on the assembly work stage, and the construction work may be stagnated.

As means for constructing a building having a large floor area, for example, a construction apparatus shown in FIG. 4 and a building construction method using the same are proposed in Japanese Patent Laid-Open No. 4-149333. That is, according to the construction device 50, the building is divided into the core portion 51 and the peripheral portion 52 thereof, and the construction device 50 is connected to the existing structure 51 of the core portion.
Core construction device 55 having a core assembly stage 54 supported by a core support column 53 that obtains a support reaction force from the core, an inner portion is provided by the core support column 53, and an outer portion is provided at a peripheral portion. A peripheral construction apparatus 58 having a peripheral assembly work stage 57 supported by a peripheral support column 56 that obtains a support reaction force from the structure 52, and the core building 51 is replaced with a peripheral building 52 It is built in advance. According to the construction apparatus 50, the assembly work stage is replaced with the core assembly work stage 5.
4 and a peripheral assembly stage 57, and the peripheral assembly stage 57 is replaced with a core assembly stage 54.
By lowering and integrating, it is possible to reduce the amount of horizontal force such as seismic force on the support column and to avoid concentration of labor, materials, and machines on the assembly work stage.

[0006]

However, in the method of building a building by the above-described conventional construction device 50 including the core construction device 55 and the peripheral construction device 58, the peripheral assembly work stage 57 is not provided. Since the inner portion is connected to an intermediate portion of the core portion support column 53, a large bending moment is applied to the core portion support column 53, and therefore, there is a problem that the members of the core portion support column 53 need to be enlarged. there were.

Further, during climbing, since both stages are climbed at the same time, the load on the climbing device of the core supporting column 53 is increased, so that the size of the device is inevitably increased. Since the core assembly stage 57 and the core assembly stage 57 are integrated via the core support column 53 so that they cannot move relative to each other, both stages rise simultaneously during climbing. Had to be stopped and workers had to wait.

The present invention has been made in order to solve the above-mentioned problems, and a method of constructing a building by a construction device including a core portion construction device and a peripheral portion construction device is disclosed. A building construction method using a construction device that can stably construct a building by preventing generation of a large bending moment and load burden on the device and reduce waiting for assembling and carrying-in work during climbing. The purpose is to provide.

[0009]

What is claimed is: 1. A method for constructing a building by a construction device comprising a support column for obtaining a support reaction force from an existing structure, wherein the building is divided into a core portion and a peripheral portion thereof, and Core construction device having a core assembly stage supported by a core support column that obtains a support reaction force from the core, and an existing structure in which an inner portion is supported by the core portion and an outer portion is a peripheral portion From A peripheral construction device having a peripheral assembly work stage supported by a peripheral support column that obtains a reaction force; and a construction device configured to construct the core building in advance of the peripheral building. In the building construction method, the peripheral part assembling work stage is integrated with the lower-stage locking means to the core part existing structure of the climbing device provided at the lower end of the core part supporting column, thereby forming the core part. There is provided a building construction method using a construction apparatus, wherein construction work is performed while being relatively moved in a vertical direction independently of an assembly work stage.

[0010]

According to the present invention, the core for assembling the peripheral part is integrated with the lower stage locking means for the existing structure of the core part of the climbing device provided at the lower end of the core part supporting column. Since it is held so as to be relatively movable in the vertical direction independently of the section assembly work stage, it is possible to prevent an excessive load from being applied to the core section support pillar and the climbing apparatus. In addition, during climbing, only one assembly work stage is always raised, and the other stage is fixed to the existing structure, so that assembly and material carry-in work can be continued,
Waiting time for workers can be reduced.
