ている（特公昭52−27446号公報参照）。[Conventional technology] Conventionally, in order to construct a steel-framed building, 1/6 pillars (center rods) out of a large number of pillars supporting a rooftop building,
A jack mechanism slidably penetrates into a large-diameter steel pipe, and the jack mechanism extends columns to form a space corresponding to one layer between the shed floor structure and the lower floor structure. After lifting up, the columns of the first floor are loaded and installed by a hoist crane between the columns of the roof floor frame and lower floor frame of this space, and the beams are installed,
Next, after the pillars slidable by the jack mechanism are pulled up into the large-diameter steel pipe installed in the upper story frame consisting of the upper and lower layers, a hoist crane is used between the upper and lower pillars of the space created by the lifting. A method is known in which a pillar is carried in and attached, a beam is installed, a beam for the first floor is constructed with the beam installed earlier, and a multi-story building is constructed by repeating this operation. (See Japanese Patent Publication No. 52-27446).

鋼管の周囲を補強する必要があるという欠点があった。[Problem to be Solved by the Invention] The above-mentioned conventional construction method enables construction under a rooftop floor at all times irrespective of the weather because there is always a rooftop floor, and works only under the rooftop floor. There is no danger of disaster due to site work, and there is no danger of crane booms or suspended loads jumping out of the site or dropping of suspended loads even on narrow premises because a tower hoist crane is used instead of a tower crane or mobile crane Although it has the effect of being able to do so, it is originally the thing that the roof floor frame is supported by many pillars, but 1/6 of those pillars are jacks and the center rod (pillar) is extended. When the shed is pushed up, the shed is supported by only 1/6 of the pillars, so if a horizontal force such as an earthquake acts, it is extremely unstable and the whole shed collapses. Fear and up and down In order to support the full load of the two-story heavy roof floor structure, it is necessary to strongly reinforce the floor on which the pillars are erected, that is, the lower floor frame part. 1 /
Column 6 is a center rod of a jack that fits into a large-diameter steel pipe column, so it has a disadvantage that the structure is complicated and that it is necessary to reinforce the periphery of the steel pipe of the upper story building.

The task is to do so.

フトアップ工法の手段を講じるものである。[Means for Solving the Problems] In order to solve the above-described problems, the present invention constructs a top floor above a lower floor, and places the top floor on a main pillar supporting the lower floor. After erecting a moving column with the height of the lower floor directly above the floor and the floor directly above the floor, and then raising the floor on the top floor to the top of the moving column with the hydraulic jack on the moving column,
The movable pillars are individually raised in the uppermost floor by an appropriate number of pillar groups by a length corresponding to the height of the main pillar supporting the floor of the immediately upper floor, and then the lower floor is lifted using an overhead crane. After connecting the main pillar supporting the floor and the main pillar supporting the floor directly above the floor,
A means of a lift-up method using a permanent pillar, which is constructed such that the beams of the floor immediately above are erected and the floor of the floor directly above is constructed by constructing the floor of the floor directly above.

ーン８が設けられている。In FIG. 1, when constructing a steel-framed building, a top floor 2 serving as a roof is first constructed above a floor 1 on a lower floor, and concrete is cast on these floors 1 and 2. Floor 1 is supported by the main pillar 3, and the hydraulic jack 6 is attached to the moving pillar 5 having a length corresponding to the height of the lower floor and the immediately upper floor temporarily joined 4 on the main pillar 3, The top floor 2 is supported on the hydraulic jack 6. In this case, moving pillar 5
Is extended upward through the floor 2 on the top floor, and an overhead crane 8 is provided on the lower surface of the floor 2 on the top floor so as to be able to travel on rails 7.

せる。Next, as shown in FIG. 2, the hydraulic jack 6 is extended to slightly raise the floor 2 on the top floor, so that the floor support bracket 9 is raised.
And then repeat the operation of changing the hydraulic jack 6 or two hydraulic jacks (not shown) before and after
By repeatedly performing the operation of alternately expanding and contracting these hydraulic jacks, the floor 2 on the top floor is raised to the upper part of the moving column 5 having the height of the lower floor and the immediately above floor, and then as shown in FIG. As shown, a large number of moving pillars 5 are individually raised for each appropriate pillar group, such as one for every ten pillars. The moving column 5 is raised by the following operation. That is, the upper end of the hydraulic jack 6 is fixed to the lower surface of the floor 2 on the top floor supported by the floor receiving bracket 9, the hydraulic jack 6 is contracted, and the moving column 5 is slightly raised to move the moving column 5 to the top floor. 2
Then, the moving column 5 is raised above the floor 2 on the top floor by a method such as repeating the operation of changing the hydraulic jack 6.

上階の床1aを構築する。Next, the overhead pillar crane 8 is used to place the main pillar 3a supporting the floor 1a on the immediately upper floor on the pillar mounting base 10 on the side of the main pillar 3 supporting the floor 1 on the lower floor. It is carried on the pillar 3 and is supported between the floor 2 on the top floor and the floor 1 on the lower floor using a temporary support pillar, or is connected to the permanent pillar 3a without using it.
After performing the above operation on all the moving pillars 5, the fourth
As shown in the figure, the overhead crane 8 is used to
A beam 1b of the floor 1a on the floor immediately above is erected between the main pillars 3a, 3a supporting the floor 1a, and concrete is cast as shown in FIG. 5 to construct the floor 1a on the floor directly above.
以上の工程を繰返すことによって必要な階数の鉄骨造
の建物を構築することができる。By repeating the above steps, it is possible to construct a steel-frame building having a required number of floors.

で補強資材と補強作業の手間が不要となる効果がある。[Effects of the Invention] The present invention allows construction work regardless of the weather because the floor on the top floor is always present, and works are performed within the height of two floors. The use of overhead cranes and no use of tower cranes or mobile cranes makes it possible to carry out construction even on narrow premises, such as crane booms or suspended loads jumping out of the premises or dropping suspended loads. In addition to the effect that there is no danger, in particular, the present invention mounts the main pillar on the floor directly above the floor by individually raising the moving pillar, so that the floor of the roof floor is conventionally 1/6 of many pillars. Unlike the one that pushes up the skeleton, it is extremely unstable and may collapse when a horizontal force such as an earthquake is applied.It is stable and has no risk of collapse. Since it is supported by main pillars, there is no need to reinforce the floor of the lower floor as in the past, and two columns of upper and lower layers, such as those in which conventional pillars for pushing up the rooftop frame are inserted into large-diameter steel pipes There is no need to have a complicated structure such as the roof floor frame, and the floor on the top floor may be a single-layer structure. Therefore, there is an effect that the structure is simple and no reinforcing materials and no labor for reinforcing work are required.
