Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a building in which a structure is erected between a plurality of building ridges so as to be rigidly connected to the building ridge.

[0002]

2. Description of the Related Art The building having the above structure has been developed in recent years and is still in the stage of research and development, but the structure to be erected between the building ridges is arranged at the upper end of the building ridge or the upper and lower middle portions. By doing so, the upper end portions and the upper and lower intermediate portions are rigidly connected to each other, and even if the building ridge itself is thin and easily bent, there is an advantage that it can be made rigid as a whole. That is known. In other words, this building can improve the rigidity of the entire building while lowering the rigidity of each building ridge, and is very useful especially for high-rise building or super-high-rise building. However, since this building has a special structure in which structures are erected in the upper and lower middle parts and the upper end part, for example, if the known means for creating the building from the bottom is adopted, the workability is very poor. .. In other words, the structure is created so that it extends over the building ridge in the structure of the structure of the building ridge, but the structure is laid between the building ridges. Creating the structure is an operation in the air, and the workability of creating the structure itself is very poor from the viewpoint of ensuring safety. Moreover, the construction period, which takes many days, cannot be started unless the structure erection points in the building ridge are created.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for constructing a building having a structure in which a structure is installed between building ridges with good workability.

[0004]

The feature of the method for constructing a building according to the first aspect of the present invention is that a building ridge construction step for creating a building ridge and at least a building among the structures at the bottom between the building ridges. After completing the structure creation process that creates up to the main part that can be erected and supported between the ridges, and the skeleton work up to the connection point with the structure in the building ridge, complete the structure creation Created in the process,
The point is that it consists of an ascending installation process of ascending to the structure erection level while being supported by the building ridge and fixing it to the frame of the building ridge, and a finishing process of completing the building ridge and the structure. The features of the building construction method according to the second aspect of the present invention are:
In the first aspect of the invention, the structure is made of steel frame, and exterior work is performed on the lower surface in the structure creating step.

[0005]

According to the first aspect of the present invention, the main work of creating the main part of the structure is performed at a safe low position such as on the ground so that the number of work of creating the structure at the erection place, that is, the high place is extremely reduced. Therefore, the safety of the work of creating the structure can be improved, and the work of creating the main part of the structure can be performed in parallel with the work of building the building. Moreover, since the main parts of the structure can be fixed to the building ridge and the remaining parts of the structure can be used for work, the already installed main parts can be used as scaffolds or work floors. The work of creating the remaining part can be performed with good workability. According to the second aspect of the invention, since the exterior work of the lower surface of the structure is performed together with the main part at the bottom of the building, the exterior work can be performed safely and with good workability.

[0006]

Therefore, according to the present invention, a building having a structure in which a structure is erected between a plurality of building ridges can be constructed with good workability, and in particular, a high-rise building or a super-high-rise building in which the structure is arranged in a high-rise building or an ultra-high-rise building. Can now provide a useful construction method when building a building. Particularly, according to the second aspect, it is possible to further reduce work that is dangerous and difficult to perform at a high place, improve workability, and shorten the construction period.
