Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of constructing an architectural/civil engineering structure, and particularly to a method of constructing a structure that can improve the productivity of construction work.

"Conventional technology and its issues" The level of productivity improvement in the construction work of architecture and civil engineering structures has lagged far behind that in the field of pond technology, and combined with the phenomenon of labor shortage in recent years, Improving the productivity of construction work has become a major challenge.

One of the factors that hinders the improvement of productivity in structure construction work is that the structure of structures is not standardized. In other words, the shapes of structures vary depending on the structure, so even if the shapes of column members, beam members, etc. are standardized, the scope to which this can be applied is limited, and the benefits of standardization are small. This is because it becomes. Therefore, the mainstream construction method is still to construct structures by assembling formwork for columns, beams, floors, and walls on-site and pouring concrete inside, and complex and various processes are performed on-site. Because of the necessity, it was difficult to improve productivity.

In addition, even when constructing a structure by constructing column members, beam members, etc. using precast concrete (PC) and assembling them, it takes time and effort to lift these PC members, which shortens the construction period. The situation was such that it was difficult to improve productivity.

This invention has been made in view of the above-mentioned circumstances, and aims to provide a method for constructing a structure that can improve the productivity of construction work.

"Means for Solving the Problem" Therefore, the invention according to the first claim of the present invention involves manufacturing a hollow block having a polyhedral external shape by combining frames in a factory or on site, and When constructing a structure by joining, a conveyance means is provided on the side of the already constructed structure, and the conveyance means conveys the blocks to the work floor, and the blocks conveyed by the conveyance means are transferred to the work floor. The above-mentioned problem is attempted to be solved by a structure construction method in which a structure is constructed by joining each block to an already constructed structure using joining means that is movable on a plane.

In addition, the invention according to the second claim is such that when a hollow block having a polyhedral external shape formed by combining frames is manufactured in a factory or at a site, and when the blocks are joined to construct a structure, an already constructed structure can be constructed. A conveying means is provided on the side of the structure, and the conveying means conveys the blocks to the work floor, and the blocks lifted by the conveying means are assembled into a block unit consisting of several blocks by an assembling means. The above-mentioned problem is to be solved by a structure construction method in which a structure is constructed by joining the block unit to an already constructed structure using a joining means configured to be movable on the working floor plane. .

FIGS. 1 to 9 are diagrams showing an embodiment in which the method for constructing a structure of the present invention is applied to a method for constructing a multi-story building having an approximately rectangular parallelepiped shape. The steps will be explained below in order.

(i) Block assembly As shown in Figures 1 and 2, the blocks that make up the building are assembled near the construction site of the building.

As shown in FIG. 2, the block 1 in this embodiment is a hollow block having a substantially cubic outer shape and is formed by combining six steel frames 2, . . . each having a substantially square outer shape. The size of one side of this block l is, for example, 60c+n,
The total ffil is said to be about several tens of kg. However, the shape, material, etc. of this block are arbitrary; for example, the block may have a rectangular parallelepiped shape or a polyhedral shape, or it may be made not only of steel but also of synthetic resin.

After the blocks 1, . . . are temporarily assembled into a predetermined shape,
It is transported by a transport means such as a belt conveyor 3 and stopped on the side of the assembly robot 4. In this case, Heltkonhair 3J:. are attached with magnifiers 5, . . . at predetermined intervals, thereby securing the blocks 1, .

The assembly robot 4 assembles the blocks 1, . . . by fixing the frames 2, . . . by welding or riveting, etc., and as shown in FIG. A connecting means 7 such as a gas arc welding machine, a spot welding machine, or an automatic rivet setting machine is provided at the tip of an arm 6.

When the assembly robot 4 finishes assembling the blocks, it
As shown in the figure, the belt conveyor 3 is moved again to convey the blocks l1... to the vicinity of the building S under construction. In addition, a bar hood (not shown) is attached to the side surface of these blocks 1, . By reading the barcode information with a barcode reader 8 provided on three sides, commands are issued to each device, which will be described later.

(ii) Block l transported to the vicinity of the building S under block lifting construction,
. . is lifted up to the working floor where the blocks 1 are currently being stacked by a lifting device (transporting means) 9 as shown in FIG.

As shown in FIG. 3, the lifting device 9 is installed on a temporary pillar 10 attached along the side of a building S that has already been constructed. This lifting device 9 includes a base l1 arranged along a temporary pillar 10, and a lifting device 1 that raises and lowers this base l1.
2, and a hook-shaped arm 1 extending upward from the base l1.
3, a track 14 fixed to the upper end of this arm l3 and extending inward of the building S, a hoist crane 15 configured to be movable on this track l4, and a hoist crane 15 suspended from this hoist crane l5. and a block gripping section 16.

The temporary pillars 10 are blocks l, which constitute the building S.
It is constructed by arranging blocks l, . . . identical to . . . in the vertical direction. Further, the lifting device 12 is
It has the same structure as the concave crane elevating device described later, and a pair of jacks 17 and 17 are installed in a row in the vertical direction, sandwiching a temporary pillar 10, and these jacks are arranged in a row in the vertical direction. The general configuration includes a jack elevator (not shown) that extends and shortens the distance between the jacks 17 and 17. Note that the structure of the block gripping portion l6 is arbitrary, but for example, as shown in FIG. 4, a magnet 18 shaped to engage inside the block l, or as shown in FIG. A pair of chucks l9 to grip
, 19, etc. are preferably mentioned.

Such a lifting device 9 expands and contracts the distance between the jacks 17, 17 arranged in the vertical direction, and lifts the jacks l7, .
...The base l1 is raised and lowered while holding the temporary pillar 10 by expanding and contracting it, and the hoist crane 15 is moved onto the track 14 while holding the block l with the block gripping part l6.
By moving the block l along the line, the block l is lifted and transported to the work floor. In addition, due to the rise of the working floor,
The temporary pillar 10 also needs to extend upward, but in the above-mentioned lifting work of the block 1, the block 1 is placed on the upper end of the temporary pillar 10 by the hoist crane 15, and the welding machine etc. attached to the base 11 is By joining this block 1 to the temporary pillar 10 using a joining device, it becomes possible to extend this temporary pillar 10 upward.

(iii) The block l lifted to the working floor by the block joint lifting device 9 is
Each block l1... is joined to the already constructed building S by a joining device (joining means) 21 attached to the portal crane 20.

As shown in FIG. 1, the portal crane 20 has a lifting device 9.

As shown in FIG. 8, this elevating device 25 includes a pair of jacks 26, 26 arranged in a row along the vertical direction and configured to move forward and backward toward the building S;
26, and a jack elevator 27 that extends or shortens the distance between the two. Therefore, normally each jack 26,...
By extending toward the building S, the lifting device 25 and, by extension, the track 22 are fixed to the side of the building S, and as shown in FIG. By expanding and contracting the distance between 26, the elevating device 25 and eventually the track 2
2 can be increased.

In this way, if the track 22 itself is configured to be able to rise, the overall height of the portal frame 23 may be slightly higher than the floor height, and the configuration of the portal crane 20 itself does not need to be large-scale.

Further, as shown in FIG. 6, the joining devices 21, 21 are attached to the running section 24 via a motor 28 that rotates along a horizontal plane and telescopic arms 29, 29. This joining device 21 is equipped with a rivet supply device 30 and a mobile air gun 3l as shown in FIG. It is carried out. Further, a gripping device 32 is provided between the arms 29, 29 so as to be extendable and retractable in the vertical direction. This gripping device 32

Thereafter, concrete may be poured into the blocks 1 that constitute the columns and beams for the purpose of structural reinforcement.

Furthermore, for locations such as partition walls that do not require much structural strength, only the block 1 is sufficient.

In addition, in this example, the floor is a deck plate (corrugated steel plate).
40 is used, and if necessary, this deck plate 4
Concrete 41 is being poured on top of 0. At this time, since the portal crane 20 is used to transport the blocks 1, . . ., there is no need to travel on the floor to transport the blocks 1, . Joining work for blocks 1, . . . can be done in parallel with the construction work. Of course, this floor may also be constructed by laying the blocks 1, . . . or may be made of PC (precast concrete) boards.

Note that each of the above devices is controlled by a control means (computer) not shown, and its procedures are synchronized.

The building S can be constructed by repeating the steps shown above. Here, in this embodiment, the steel frame 2,
Cubic hollow block l1 combining ...
A building S is constructed by stacking up blocks and connecting them to each other, and all pillars, beams, etc. of the building S are constructed using this block l1...
・Since the structure is based on ・, it is possible to significantly standardize the parts. Therefore, it is possible to completely standardize the construction process of the building S, such as assembly, transportation, and joining of the blocks l, . . . , and can greatly contribute to improving productivity. By standardizing the construction process of the building S, it becomes possible to fully apply industrial robots and the like to each process as in this embodiment, which can further contribute to productivity improvement.

Moreover, in this embodiment, a cubic hollow block 1 is used as a member constituting the building S, and the block l itself is very lightweight compared to conventional precast concrete +- (pc) members. A large-sized lifting machine is not required for transportation work such as lifting, and a hoist crane 15 or the like used for normal cargo transportation as in this embodiment is sufficient. Therefore, from this point of view as well, mechanization of each process including the lifting process can be promoted. Furthermore, by reducing the weight of the members, it is possible to simplify the equipment, etc. that make up each process, which can greatly contribute to reducing initial costs.

The building S is constructed by using this assembly device 41 to assemble a block unit 42 in which blocks l1... are arranged in one or two rows, and by joining these units 42 using a joining device 43. .

The configuration of the assembly device 41 is the same as that of the joining device 2l of the previous embodiment. However, this assembly device 41 is fixedly installed on the floor near the upper end of the lifting device 9.

On the other hand, the joining device 43 is configured to be movable on the work floor plane, receives the unit 42 from the assembly device 4l, transports it to the work site, and joins it to the building S.

Therefore, this embodiment can also provide the same effects as those of the previous embodiment. In particular, in this embodiment, the blocks 1, . can.
