BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for underground construction by a fully automatic building construction system using an automatic construction device.

[0002]

2. Description of the Related Art In recent years, a fully automatic building construction system for automatically constructing a high-rise building using an automatic construction apparatus has been proposed, for example, by the Construction Technology Newspaper dated August 17, 1991. By automating the construction work of the building using the fully automatic construction system in this way, it is possible to achieve significant labor saving and shortening of the construction period, and also to utilize such automatic construction equipment from the stage of underground construction. By doing so, the effect can be further improved.

[0003]

However, such a conventional full-automatic construction system is usually used for the construction of the above-ground portion, and when this full-automatic construction system is utilized from the stage of underground construction. It is conceivable that the underground construction will be carried out with the automatic construction equipment installed on the ground first. However, when performing underground construction after installing the automatic building device on the above-ground part, when constructing a pillar in the underground part, the already built automatic building device interferes with the work efficiency of the underground part. There was a problem that it would be significantly reduced.

In view of such conventional problems, the present invention can remarkably improve work efficiency by constructing a pillar for an underground portion and then installing an automatic construction apparatus using the pillar. The purpose is to provide a construction method for underground construction using a fully automatic building construction system.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 is a sectional view showing an embodiment of a construction method for underground construction by the fully automatic building construction system according to the present invention.

That is, in the construction method for underground construction by the fully automatic building construction system of this embodiment, first, the continuous underground wall 12 is constructed around the portion where the building is to be constructed on the ground 10. As is generally known, the continuous underground wall 12 is constructed by excavating a groove having a predetermined width in the ground 10 and placing concrete in the groove. Then, a plurality of pile holes 1 are formed inside the continuous underground wall 12 at predetermined intervals.
4, 14, ... Are excavated, and a rebar cage for piles (not shown) is inserted into a portion of the pile holes 14, 14 ... below the root cutting bottom 16 to pour concrete 18 for piles.

Next, when the poured concrete 18 for piles is uncured, the underground pillars 20 which are permanently installed are inserted into the pile holes 14, 14 ..., and these underground pillars 20 are uncured concrete 18 for piles. Rooted in and installed. still,
A semi-PC pillar is used as the underground pillar 20. By the way, the underground pillar 20 is a long pillar 20 installed so as to project from the ground.
a, 20a ... and short columns 20b, 20 that can be stopped on the ground
b, and the long columns 20a, 20a ... And the short columns 20b, 20b ... Are alternately installed so that the long columns 20a are in contact with the continuous underground wall 12.

After the concrete 18 for piles is hardened, the automatic construction device 22 is installed across the portion where the long columns 20a, 20a ... The automatic construction device 22 includes a moving frame 24 and an upper crane girder 26 attached to an upper portion of the moving frame 24.
And a lower crane girder 28 attached to the lower part, and an overhead crane 30 is movably attached to the lower crane girder 28 in this embodiment.

The moving frame 24 is composed of long columns 20a,
These long columns 2 are formed in a frame shape so as to cover the outer periphery of the long columns 20a.
0a, 20a, ..., And the pillars of the above-mentioned ground portion, which are successively added to the upper ends of these long pillars 20a, 20a, can be climbed (moved upward). That is, the lifting device 32 includes a pair of upper and lower tightening bands 32a and 32b.
And a telescopic jack 32c attached between these tightening bands 32a and 32b.
By expanding and contracting the expansion / contraction jack 32c along with alternately releasing a and 32b, the expansion / contraction jack 3
The extension of 2c is used as a movement unit to sequentially move upward.
The automatic construction device 22 includes an upper crane girder 2
A membrane roof 34 is laid across the upper side of 6, and by covering the work site with the membrane roof 34, work in rainy weather is possible.

After the automatic construction device 22 is installed, a beam member (not shown) is assembled to the above-ground protruding portions of the long columns 20a, 20a ... And these long columns 20a, 20a. The inside of the continuous underground wall 12 is primarily excavated by using an excavator 36 such as a power shovel to expose the underground pillar 20 on the first basement. When the underground pillar 20 on the first basement floor is exposed in this manner, the automatic construction device 22
The beam member 38 is transported by using the overhead crane 30, and the beam member 38 is installed and fixed between the underground columns 20. After the beam material 38 on the first basement floor is installed in this manner, the secondary material is further excavated to expose the underground pillars 20 on the second basement floor, and the beam material carried by the overhead crane 30 between the exposed underground pillars 20. Install 38. In this way, excavation is sequentially performed on the lower floors, and the beam member 38 is installed between the exposed underground columns 20.

Therefore, in the fully-automatic building construction system using the construction method for the underground construction of this embodiment, first, the concrete 18 for piles is placed in the portion below the root cutting bottom 16 of the pile hole 14 excavated in the ground 10. Then, after the underground pillar 20 is erected by being embedded in the concrete 18 portion, the automatic construction device 22 is installed between the long pillars 20a, 20a ... Of the underground pillar 20. Then, while performing the primary excavation, the secondary excavation ... of the underground portion, the beam member 38 is installed between the underground pillars 20 which are sequentially exposed from the underground first floor portion, the underground second floor portion ... Therefore, since the automatic construction device 22 is installed after the underground pillar 20 is erected, the automatic construction device 22 enables the underground pillar 20 to be erected without any hindrance, and in turn, the construction of the underground pillar 20. It can be done smoothly and accurately. Therefore, in this embodiment, the same system can be used from the start of the underground construction to the final stage of the skeleton of the ground construction by using the fully automatic building construction system, and it is possible to significantly shorten the construction period of the building construction and reduce the construction cost. it can.

Further, in the present embodiment, since the automatic construction device 22 is installed by utilizing the long columns 20a, 20a ... Of the underground column 20, the automatic construction device 2 is additionally provided on the ground portion.
Since it is not necessary to construct the second mounting pillar, it is possible to significantly reduce the cost. Further, when excavating the underground portion, since the beam member 38 is installed between the underground pillar 20 that is sequentially exposed from the underground first floor portion, the underground second floor portion ...
These beam members 38 function as piers, beams, etc.
The space can be reinforced, and the cost can be reduced from this point as well.
