Then, the time interval (hereinafter, referred to as “cycle time”) from when one conveyed product is carried in to when the next conveyed product is carried in becomes long,
There is a problem that the progress of the construction depends on the progress of the material transportation work, which causes the extension of the construction period. In addition, in order to convey long or heavy objects such as main columns, girders, or members on the lower floors, it is necessary to make the carrying capacity of the lifting equipment compatible with this. The equipment will naturally be large-scale. However, in the case of transporting other short and lightweight materials, there is a problem in that such a lifting device cannot fully utilize its transporting ability and is inefficient.

At this time, as shown in FIG. 16, the carriage 16 is sequentially added along with the extension of the guide rail 15 of the vertical transport device 7. Then, as shown in FIG. 7, the plurality of carriages 16 convey the material upward while delivering the material like a bucket brigade.
In this way, when the uppermost floor 150F of the building 1 is constructed, the construction of the building 1 as shown in FIG. 1 is completed.

(Dismantling / Removing Method of Transport System A) After building the building 1, in order to dismantle / remove the transport system A, first, the transport vehicle V and the assembly robot 50 are lowered to the ground portion G by the vertical transport device 7. . Next, the base yard 8
The rail unit 17 attached to the side surface of the building 1 is removed and the CW plate 5 is attached to the portion where the rail unit 17 is removed while lowering the rail by 1F. Then, the removed rail unit 17 is operated by the vertical transport device 7 in the reverse order of the above-described extension method of the guide rail 15, and is lowered to the ground portion G. By dismantling the base yard 8 when the base yard 8 is lowered to the above-ground part G in this way, the dismantling and removal of the transport system A is completed.

As a result, the long pillar steel frame 2 and the like are supported by the carriages 16 and 16 of the vertical transfer devices 7 and 7, and both carriages 16 and 16 can be moved by being synchronously raised. In this way, when transporting general materials, the two vertical transport devices 7, 7 are separately operated to perform the transport work, and only when transporting a long material, both are synchronized and operated to transport. By performing the work, the vertical transfer device 7 can be flexibly adapted to various forms of materials, and the transfer work can be efficiently performed.

In addition, the carriage 16 of the vertical transfer device 7,
It is configured such that the 16 can be moved up and down in a synchronized manner while being vertically stacked. As a result, the load of the material is supported by the vertically stacked carriages 16 and 16, and the carrying capacity (load that can be carried) of the carrying stand can be improved. Therefore, even a heavy object is carried. It is also possible to make the vertical transfer device 7 capable of flexibly accommodating various forms of materials.
It becomes possible to carry out the transfer work efficiently.

Further, the guide rail 1 of the vertical transfer device 7
The rail unit 17 that forms part 5 of the grip bracket 2
It is configured to be supported by the pillar C of the building 1 by 0. As a result, the load of the vertical transfer device 7 and the material to be transferred is supported by the building 1, and it is not necessary to use a special support work or the like for supporting the load from the ground, and the installation / disassembly of the rail unit 17 is performed. Can be done easily.

In addition, the above-mentioned transfer system A has a construction in which the stock yard 6, the vertical transfer device 7, the base yard 8, and the horizontal transfer device 9 are provided. As a result, when the material is transported from the above-ground portion G to the construction floor 1a, the material can be transported without using a tower crane as in the conventional case, and the work safety is not affected by the wind. Moreover, even if there are existing buildings and roads nearby, it is possible to transport materials without any hindrance. Furthermore, by pre-programming the operation of each device of the transport system A,
It is also possible to automate the entire construction of the building 1.

In the above embodiment, the number of vertical transfer devices 7 installed is not limited to two.
Also, the structure of the carriage 16 is not limited as long as the material can be transported. For example, as shown in FIG. 17, the carriage 1
A suspender 57 is formed on the lower surface of the support arm 27 of 6,
Plate-shaped materials such as the PC floor board 4 and the CW board 5 may be hung and transported. In addition, the rail unit 17
Has the same length as the floor height of the building 1, for example, but is not limited to this. Further, from the viewpoint of functional aspects such as the power supply, the control signal, and the movable range of the carriage 16, the plurality of rail units 17 may constitute one unit, so to speak. Further, as an example of the lifting system, the vertical transport device 7 for vertically transporting the material is used, but in addition to this, the lifting system is applied, for example, at the time of construction of an underground structure to transport the material upward. From below, the rail may be conveyed downward, and the rail may be extended downward as the construction progresses. Alternatively, the lifting system may be installed diagonally. It goes without saying that the same effects as described above can be obtained in these cases as well. Further, the vertical transport device 7 that constitutes the transport system A
Other than that, the stockyard 6, the base yard 8, and the horizontal transfer device 9 are not limited in their configurations, and may have any configuration. Of course, only the vertical transport device 7 may be used alone. In addition to the above-mentioned pillar steel frame 2, beam steel frame 3, PC floor board 4, CW board 5, and stairs 56, for example, wall panels constituting the inner wall of the building 1 Equipment,
It goes without saying that other materials may be transported.
