As a result, the frame 5 for constructing the frame 1 having a substantially letter shape in a plan view is set at the place where the frame 1 is to be built. Thereafter, the receiving frames 30, 31 and the like are removed.

Next, as shown in FIG. 4, a new column unit 10 is lifted on each column 7 by using a jib crane 16 provided on the frame 5 for building a frame, and the new column unit 10 is erected and added. Thereafter, the elevating mechanism 11 provided on each of the columns 7 is simultaneously operated to raise the main frames 6 and 6, the center frame 8, and the side frames 9 by a predetermined dimension.

Then, as shown in FIG. 1, the materials are transported by using the jib crane 16 and the overhead crane 20 provided on the frame 5 for building the skeleton, and the skeleton 1 is built up to, for example, the third floor. At this time, the jib crane 16 mainly performs lifting and conveying from the ground, and the overhead crane 20 horizontally conveys the material lifted by the jib crane 16,
This is transported to a predetermined position to be assembled.

Thereafter, the above operation is repeated, the column unit 10 is lifted by the jib crane 16, the column 7 is added, and the main frames 6, 6 and the center frame 8 and the side frames 9 are raised. The steps of stacking and building the skeleton 1 with the jib cranes 16 and the overhead cranes 20 provided on the center frames 8, 6 and the side frames 9 are alternately repeated. At this time, every time the support 7 is extended a predetermined length,
The column 7 is locked to the frame 1 by a horizontal stay (not shown).

Then, as shown in FIG. 5, when the frame 1 is constructed up to the top floor, the above operation is completed. Thereafter, the frame 5 for building the skeleton is dismantled and removed as follows. First, as shown in FIG. 6A, the second rail 22 and the hoist 23 of the overhead crane 20 are stored in the main frame 6, and the openable roof (not shown) is opened. Next, as shown in FIGS. 6B and 6C, the side frames 9 and 9 are
6 and moved to the end portions 6a, 6a of
It is retracted outward from d and is fixed to the main frames 6 and 6 in this state. Next, similarly, the center frame 8 is similarly moved to the ends 6a, 6a of the main frames 6, 6 and retracted outside the side surfaces 1c, 1d, and is fixed to the main frames 6, 6 in this state. As a result, the frame 5 for building the frame 1 has the main frame 6, the center frame 8, and the side frame 9 formed in a substantially rectangular shape in plan view, and the side surfaces 1a, 1b, 1c,
It will be in a state located outside of 1d.

Next, as shown in FIG. 7, the raising and lowering mechanisms 11 of the columns 7 are simultaneously operated to lower the main frame 6, the center frame 8 and the side frames 9 (see FIG. 6) by predetermined dimensions. The uppermost column unit 10 is projected. Subsequently, the uppermost column unit 10 protruding with the jib crane 16 is removed, and the column unit 10 is lowered to the ground.

Thereafter, as shown in FIG.
The lowering process of the main frame 6, the center frame 8 and the side frames 9 (see FIG. 6) by 1 and the dismantling process of the support unit 10 by the jib crane 16 are sequentially repeated. When the elevating mechanism 11 is lowered to the lowermost part of the column 7, as shown in FIG. 9, the main frame 6, the center frame 8 and the side frames 9 are assembled using the jib crane 16, the crane truck 32 and the like. These are dismantled in the reverse procedure, and
Is disassembled and removed. Thus, the disassembly and removal work of the frame 5 for building the frame after the completion of the building of the frame 1 is completed.

If, for example, a typhoon or the like occurs during the work of stacking and building the frame 1 using the frame 5 for building the frame, the center frame is constructed in the same manner as when the frame 5 for building the frame is dismantled. After the 8 and the side frame 9 are moved to the end 6a of the main frame 6, they are lifted down by the lifting mechanism 11. Thereby, the wind pressure acting on the frame 5 for building the frame can be reduced, and further, it can be lifted down and deposited in the frame 1, so that the load on the frame 5 for frame building can be reduced.

In the above-described frame 5 for building a skeleton and the method of building the skeleton 1 using the same, the main frames 6 provided on the outer sides of the two opposing side surfaces 1a and 1b of the structure 1 to be built, respectively. 6, a column 7 that is gradually added according to an increase in the height of the frame 1, an elevating mechanism 11 provided on the column 7 to move the main frame 6 up and down, and a center movably provided along the main frame 6. A frame 8 and a side frame 9, a jib crane 16 provided on the main frame 6, and an overhead crane 20;
The center frame 8 and the side frames 9 are configured to be movable along the main frame 6 to positions outside the other side surfaces 1c and 1d of the structure 1. Thus, in the frame 5 for building a skeleton, when the skeleton 1 is to be built, the skeleton 1 is built up using the jib crane 16 or the overhead crane 20 below the main frame 6, the center frame 8 and the side frames 9. be able to. The main frame 6, the center frame 8, and the side frames 9 are raised by the elevating mechanism 11 along the columns 7 while extending the columns 7 in accordance with the increase in the height of the skeleton 1 due to the progress of the construction. Thereby, construction of the frame 1 can be performed efficiently. When the support unit 10 is added to extend the support 7, the jib crane 16 for transferring the material can be used as it is, so that there is no need to use a large-scale crane or a special mechanism as in the related art. Thus, the cost can be reduced and the operation rate of the facility can be improved.

After the construction of the frame 1 is completed, the center frame 8 and the side frames 9 are moved along the main frame 6 to a position on the outer side of the structure 1 to be lowered. Thus, the column 7 can be dismantled by the jib crane 16, and the main frame 6, the center frame 8 and the side frames 9 can be dismantled on the ground. In this way, work at a high place can be significantly reduced, and work efficiency and work safety can be improved. Furthermore, even in the case of a typhoon or the like, the load on the frame 5 for building a skeleton can be minimized by lifting down the main frame 6, the center frame 8, and the side frames 9.

In the above-described embodiment, an openable / closable roof member (not shown) is provided on the upper surface of the frame 5 for frame building. However, the structure is not limited at all. It is also possible to use a roof material made of such a material, or to link the center frame 8 and the side frames 9. In addition, the mainframe 6
The side frame 9 may be provided with a side frame that covers the side of the upper construction site of the frame 1 under construction, or a curing sheet may be stretched over the side frame. Thereby, the weather of the construction site can be made all-weather, the working environment can be improved, and the construction period can be prevented from being prolonged.

The frame 5 for building the frame and the frame 1 to which the method of building the frame using the frame 5 is applied are not limited to those described above. The length of the main frame 6, the center frame 8 and the side frames 9 is not limited. By changing the number, the position of the columns 7, the number of columns, and the like, the present invention can be similarly applied to a frame having another shape. Of course, the size and number of the jib crane 16 and the overhead crane 20 may be appropriately selected.
In the case where is small, the overhead crane 20 may be omitted. Further, the type of the elevating mechanism 11 is not limited at all, and any type may be used as long as the main frame 6, the center frame 8 and the side frames 9 can be moved up and down. And such a frame 5 for building a skeleton,
Since it is independent of the frame 1 to be built, it can flexibly cope with buildings of various shapes, as well as by changing the number and models of the combination of frames to be constructed and the lifting mechanism, overhead crane, etc. A highly versatile system that can easily cope with changes in the scale of the building to be built can be obtained, and the economic effect is great.

Further, in the above-mentioned embodiment, although the specific construction procedure of the frame 1 is not described, the column 2 and the beam 3 are not described.
It goes without saying that floors, walls, exterior walls, interiors, facilities and the like are sequentially constructed.

Other than this, any configuration may be adopted as long as it does not deviate from the gist of the present invention, and it is needless to say that the above-described configurations may be selectively combined appropriately. No.

It is configured to be movable to a position on the outer side of the structure. According to the frame for building a frame according to the second aspect, the sub-frame is provided with the overhead crane. In such a frame for building a frame, when building a structure, the frame is stacked and built using a lifting mechanism and an overhead crane below the main frame and subframe, and the height of the frame increases due to the progress of construction. Accordingly, the main frame and the sub-frame are raised by the elevating mechanism along the columns while extending the columns. Thus, the frame can be efficiently constructed, and a temporary roofing material or the like can be stretched on the upper surface of the frame, so that all weather at the construction site can be achieved. In addition, since the lifting mechanism for transporting materials can be used as it is when adding columns, it is not necessary to use a large-scale crane or special mechanism as in the past, reducing costs and operating equipment. The rate can be improved. Further, after the completion of the building of the skeleton, the main frame and the sub-frame can be lowered along the columns by moving the sub-frame along the main frame to a position on the outer side of the structure. Therefore, the columns can be dismantled by the lifting mechanism, and the mainframe and the subframe can be dismantled on the ground. In this way, work at a high place can be significantly reduced, and work efficiency and work safety can be improved. Furthermore, in the case of typhoons,
By lowering the main frame and the sub-frame, the load on the frame for building the skeleton can be minimized. In addition, since the frame for building a skeleton including such a main frame and a sub frame is independent of a structure to be built, not only can it flexibly cope with buildings of various shapes, but also the frame to be configured By changing the number and type of lifting mechanisms and overhead cranes, etc., it is possible to easily cope with changes in the scale of the building to be constructed, and the economic effect is significant.
