DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for building a building.
It is particularly suitable for use in the construction of high-rise buildings.

[0002]

2. Description of the Related Art In general, a high-rise building is constructed by using a climbing crane to lift building members such as pillars, beams, floors and the like from the ground, and building the building sequentially from a lower floor to an upper floor in units of members. There is a way to be done. With the aim of efficiently constructing such a building, a construction method in which the top floor of the building to be constructed is pushed up with a hydraulic jack and the building is advanced below the building (Japanese Patent Laid-Open No. 2-7084)
4) has been proposed.

[0003]

In each of the above-mentioned conventional methods, members such as pillars, beams, floors, etc. of a building are carried in order from the ground to a high place, and one member at a time on a building floor at a high place. Since the components are stacked and joined, it takes time to carry and transport the components.
The construction period was long, and it was difficult to shorten the working time and the construction period. In addition, in order to proceed with construction while jacking up the top floor of the building, it is necessary to lift large temporary equipment such as hydraulic jacks and cranes to work on high places,
In this case, it becomes a hindrance to carrying in and joining members on the working floor at a high place, and the way of working is complicated to avoid interference, which has increased the danger. In the final stage of building construction, there were also problems such as the difficulty in dismantling and removing these temporary equipment in a narrow space.

[0004]

According to the present invention, there is provided a method for constructing a building, comprising assembling a rooftop floor on the ground as an erecting structure, and a lower end capable of being fitted on a main building pillar. An outer temporary column and an inner temporary column are provided so as to be able to move up and down by penetrating the rooftop section, and elevating and fixing means for vertically driving the outer temporary column and the inner temporary column with respect to the rooftop section are provided. A traveling rail extending in a direction in which the outer temporary pillar and the inner temporary pillar are arranged under a floor portion, a traveling means having a hoisting device is provided on the traveling rail, and a lower end of the outer temporary pillar is attached to the building. The roof floor portion is positioned at the uppermost stage of the outer temporary column by the elevating and fixing means and fitted on the main column to be in the first state, and the traveling is performed at a position where the inner temporary column is not located in the first state. By moving the means, the first permanent block is erected by the hoisting device, The lower end of the temporary column is fitted onto the first permanent block, the outer temporary column is pulled upward, and the roof top floor is positioned at the uppermost stage of the inner temporary column by the elevating and fixing means. In the second state, the traveling means is moved to a position where the outer temporary column is not located, a second permanent block is erected by the hoisting device, and a lower end of the outer temporary column is fixed to the second permanent block. By fitting the upper part and pulling the inner temporary column upward, the roof top floor portion is positioned at the uppermost stage of the outer temporary column by the elevating and lowering means, and the first state is again set. Characterized by the construction of

The lower end of the temporary column is fitted onto the second permanent block, the inner temporary column is pulled upward, and the roof floor is located at the top of the outer temporary column by the elevating and lowering means so as to be in the first state again. The building was constructed by repeating Can be performed immediately construction in the process of the same procedures come after the assembly of the mechanical equipment of the structure of the upper floor portion from a floor of the building, site work is simplified easily. Also, the work of transporting the main block has been simplified,
The hoisting capacity of the hoisting device can be easily increased, and transport and installation can be performed in units of large blocks, thereby greatly shortening the construction period. In addition, since the outer temporary pillars and the inner temporary pillars are used alternately while being fitted to and supported by the permanent block, the support of the rooftop floor is stable, and the transportation and installation work is performed on the building floor below the rooftop floor. Work is safe and easy. In particular, in the final stage of building construction, there is no interference between the transport, the building and the erection structure, and the dismantling and removal of the temporary machine and the joining and fixing of the rooftop are very easy and smooth.
