Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to lifting a main building portion as an upper layer constructed on a main building portion of a lower layer and fixing it to a predetermined height position by a robot or the like. The present invention relates to a construction method in which a building having a desired height is repetitively performed by a construction plant equipped with.

《Prior art》 Generally, construction of various buildings such as middle- and high-rise buildings is performed by constructing pillars up to the top floor and then sequentially pulling up and installing slabs assembled on the ground with winches, or using frame members such as cranes. Lift, 1 from lower floor to upper floor
This is done by a method of building and stacking each floor.

In addition, recently, for example, as disclosed in Japanese Patent Publication No. 52-26044, after intensively producing a building skeleton for the first floor at the ground level, after completing the skeleton construction for the first floor,
A method of constructing the entire building by repeatedly lifting up with a jack or the like and fixing it at a predetermined height position has also been proposed, aiming to shorten the construction period and reduce the construction cost. Incidentally, in the construction method disclosed in the above publication, a staircase is constructed in advance at positions that are on both sides of the building,
A beam assembly is installed between the tops of the staircases, and the beam assembly supports jacks for lifting.

<Problems to be solved by the invention> However, in the conventional construction method as described above, since the slab and the frame member are pulled up by the winch or the crane and the construction work is advanced, the skill of the worker and a large number of manpower are required. In other words, it is difficult to construct a systematic building by mechanical force, and there is a problem that it is difficult to improve productivity such as automation rate and shortening of construction period.

In that respect, in the technology disclosed in the above-mentioned publication, since the building skeleton is intensively produced at the ground level, the construction is exclusively ground work, and the mechanical force of the work robot or the like can be easily introduced. Although such problems can be solved to some extent, it is necessary to first construct the staircase that will be the support tower of the beam assembly at the desired height, and it is not possible to work in parallel with other processes, so the construction period can be shortened. There was a limit.

In addition, the building frame must be supported by the staircase during construction, and the height of the building is limited due to the strength of the staircase, etc., which is not applicable to super high-rise buildings. It was Therefore, if you increase the size of the staircase and increase its strength, the building can be made higher by that amount, but the staircase part will become unnecessarily large and the construction period required to build the staircase in advance will increase and the cost will increase. There was a problem such as inviting.

The present invention has been made in view of the background as described above, and it is possible to eliminate the need for manual work, improve productivity such as shortening the construction period, and particularly preferable when constructing a super high-rise building. The purpose is to provide applicable construction methods.

<< Means and Actions for Solving the Problem >> The present invention constructs a plurality of main pillars at a predetermined height, and the uppermost floor main building portion that is hung between these main pillars and can be moved up and down along the main pillars. , The top main building part is lifted up by a plurality of floors, and the bottom main building part is fixedly constructed between the main columns by a building plant provided in the top main building part, and then , Constructing a new main building part between the main pillars on the main building part located directly below the top floor main building part by the building plant of the top floor main building part, and the top floor main building part and Repeat the process of lifting up the new main building portion for a plurality of floors and fixing the new main building portion in a predetermined position to build up the main pillar to the lift-up position of the top floor main building portion. It is characterized in that it is done in advance.

According to the method as described above, the bottom floor main construction portion is constructed by the construction plant provided in the top floor main construction portion, and thereafter, the “lifted up top floor main construction portion is located immediately below and already constructed. On top of the main building section, build a new main building section to be placed above it, and lift up the built main building section to a predetermined height below the top floor main building section to form a main pillar group. By repeating the "fixing work", a plurality of main building parts are sequentially stacked in the height direction between the elevated top building part and the bottom floor building part to build a building. Therefore, the construction work of the main construction portion and the lift-up work of the main construction portion which has already been constructed and serves as the base of the construction work can be carried out in parallel. This can significantly reduce the construction period and improve productivity.

In addition, since the top floor main construction part is hung on and supported by the main pillar group that is the framework of the building,
Sufficient supporting strength can be obtained, and it can be preferably applied to the construction of super high-rise buildings.

Further, the construction of these main pillar groups may be carried out slightly ahead of the lift-up height of the main building portion of the top floor, so that the construction work of these main pillar groups can proceed in parallel with the above-mentioned various construction work and the like. It is possible to further shorten the construction period.

Further, the present invention relates to the above-mentioned construction method, in parallel with lift-up of the top floor main building portion, construction of a main construction portion other than the top floor main building portion and bottom floor main building portion, or construction of the main pillar. , A plurality of sub pillars are erected between two main building portions adjacent to each other in the height direction, and can be moved up and down along the sub pillars on the lower main building portion of the two main building portions. Build a sub-beam structure, lift up the sub-beam structure and fix it to the uppermost floor position between the two main building parts, and then build a new sub-beam structure and lift it up. It is characterized in that the step of fixing the uppermost floor position to the lower floor position is repeated.

In this way, regarding the construction of the sub-construction part that is advanced between the upper and lower main construction parts, after the construction of the sub-column group, the construction work of the sub-beam skeleton and its lift-up work are repeated in the lower main construction part. The construction work can be carried out in parallel with other various construction work, etc., and the construction period can be significantly shortened even for buildings including such sub-construction parts. You can
