Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a building suitable for use in constructing a large flat building, for example, a shopping center or a warehouse.

[0002]

[Prior Art] Shopping centers, warehouses, factories, etc.
When constructing the frame of a building having a large flat area, it is common to use a large crane truck or a lifting machine such as a tower crane.

[0003] As a method of constructing a frame of a building having a large planar shape using such a large lifting machine, for example, there is the following method.

First, as shown in FIG. 7, a temporary passage space 2 extending from the outer peripheral portion to the inside of a frame 1 to be constructed is secured, and a large lifting machine is entered into the temporary passage space 2 to surround a portion around the temporary passage space. After building the skeleton 1A up to the top floor,
There is a method of constructing the temporary passage space 2 by post-processing. As shown in FIG. 8, a hole-shaped space 5 for installing a lifting machine 4 such as a tower crane is secured in an inner portion of the skeleton 1 to be constructed, and the lifting machine 4 installed in this space 5 is used. There is also a method of constructing the skeleton 1B of the surrounding portion in advance, removing the lifting machine 4, and constructing the skeleton of the space 5 by post-construction.

Further, as shown in FIG. 9, there is also a method of extending the boom 6a of the lifting machine 6 from the outer peripheral side of the frame 1 to be constructed to construct the frame 1.

[0006]

However, the above-described conventional frame building method has the following problems. First, in the method as shown in FIGS. 7 and 8, since the temporary passage space 2 and the hole-shaped space 5 are post-processed, it takes time to construct the frame 1 itself. In addition, construction work such as equipment and interior finishing is delayed when waiting for the completion of the skeleton of the entire floor, and conversely, when construction starts with the temporary passage space 2 and the hole-shaped space 5, the temporary passage After completion of the space 2 and the hole-shaped space 5, the equipment / interior finishing work of this portion must be performed separately, which is inefficient. Furthermore, since the work is performed at a high place around the temporary passage space 2 and the hole-shaped space 5, it is necessary to provide a scaffold, a curing net, and the like, and there is a problem that the cost of the temporary construction work increases.

On the other hand, as shown in FIG. 9, in the method of performing construction from the outer peripheral side of the skeleton 1, such a method cannot be adopted unless a sufficient space is first secured in the outer peripheral portion. In addition, when the work is performed from the outer peripheral side, the working range of the lifting machine 6 is increased, and accordingly, the lifting machine 6 is also increased in size. However, a lighter object is suspended, and the utilization efficiency of the lifting machine 6 is increased. There is a problem that becomes worse.

Base members (not shown) are provided on the lower surfaces of both ends thereof, and each base member is offset with respect to a position where the load of the transport vehicle 35 is received. Even if the use rail 36 is bent, the lower surface thereof is prevented from contacting the upper surface of the floor 13.

The lifting device 20 and the transfer device 21 as described above
A method of constructing the construction floor of the skeleton 10 using the lifting system comprising

First, two sets of lifting machine running rails 23 are connected and installed at the end of the construction floor of the frame 10. Then, the hoist 22 is placed on the hoist traveling rail 23 located at the end of the construction floor.

Next, the lifting machine 22 is moved to the lifting rail 2
3 and move on another set of lifting machine traveling rails 23 in front of the traveling direction. Then, the receiving member 30 is set on both sides of the hoist 22, the outrigger 26 is stretched so that the load of the hoist 22 is received by the receiving member 30, and the ground surface of the outrigger 26 and the receiving member 30 are integrated with the clamp metal 31. Fixed to.

Subsequently, the trailing hoist traveling rail 23 is lifted by the boom 27 of the hoist 22, and this is lifted by the hoist 2.
2 is moved to the front side of the lifting machine traveling rail 23 on which is mounted and connected. Then, after moving the hoist 22 to the front hoist traveling rail 23 this time, the rear hoist traveling rail 23 is lifted by the boom 27 and moved forward.
At this time, the outrigger 26 is once contracted, but the receiving member 30 is kept integrated with the ground surface of the outrigger 26 by the clamp metal 31.

Thereafter, by repeating the above operation, the two sets of lifting machine traveling rails 23, 23 are alternately sent forward, and the lifting machine 22 can be advanced like a so-called insect.

Further, on the rear side of the hoisting machine 22, for example, two sets of truck rails 36 for the transporting device 21 are laid in parallel with the construction floor end of the frame 10. Then, the carriages 35 are mounted on the rails 36 for the carriages, respectively.
1, the members such as the beam 12, the floor 13, etc., and the rail 36 for the trolley for extension, etc. are transported.

Then, the two sets of the lift traveling rails 2
While the hoisting machine 22 is sequentially moved to the opposite end of the construction floor by using 3 and 23 alternately, the bogie rail 36 for the transfer device 21 is gradually extended behind the hoisting machine 22.

The end of the hoisting machine 22 on the opposite side of the construction floor (the "end" in this case is defined as a position where the turning range of the boom 27 can assemble the pillar 11 or the like located on the outer periphery of the construction floor. ), The movement of the lifting machine 22 is stopped.

Thereafter, as shown in FIGS. 2 and 3,
The members such as the pillars 11, the beams 12, and the floor 13, which constitute the building 10 on the construction floor, are sequentially transported to the rear of the hoisting machine 22 to the transporting cart 35 of the transporting device 21.
It is lifted by the second boom 27 and is sequentially assembled at a predetermined position on the construction floor. At this time, the skeleton 10 of the construction floor concerned is
The work is performed in the order shown in the above (1) (see FIG. 1).

In this manner, the crane 22 is sequentially retracted while constructing the frame 10 on the construction floor. At this time, the hoist 22 is connected to the two sets of hoist traveling rails 2.
3 and 23, the lift traveling rail 2 located on the rear side
3 and the step of lifting the front lifting machine traveling rail 23 by the boom 27 and moving the same rearward, and thereafter, the step of retracting the lifting machine 22 are sequentially repeated. For the truck rail 36 for the transfer device 21,
With the retreat, remove the truck rail 36 at the front end,
This may be removed rearward by the transport trolley 35.

In this way, it is only necessary to sequentially construct the building 10 on the construction floor from the opposite end to the end while using the crane 22 while retracting the crane 22.

According to the above-described configuration, even in a large-plan building, each floor can be completely constructed without any post-construction portion. It is possible to adopt a construction method of layering construction. As a result, unlike the related art, there is no portion to be post-constructed, so that the efficiency of construction can be improved. In addition, there is no need to provide a scaffold, a curing net, or the like in a portion to be post-constructed, so that temporary construction costs can be reduced.
In addition, since the frame 10 of each floor is completely completed, it becomes possible to start construction of the equipment and interior finishing work of each floor at an early stage. In this way, it is possible to greatly improve the construction efficiency of the building, and to reduce the cost and the construction period.

Also, since the lifting machine 22 is advanced by using two sets of the lifting machine traveling rails 23 and alternately sending them forward, the lifting machine 22 can be moved with the minimum lifting machine traveling rails 23. And equipment costs can be kept to a minimum.

Further, the receiving member 30 is connected to the outrigger 26.
The receiving member 30 is automatically moved with the movement of the lifting machine 22 once the mounting member is attached to the grounding portion, so that the receiving member 30 needs to be separately rearranged. And the lifting machine 22 can be easily moved.

In addition, materials to be assembled and the like are transported by the carriage 35 traveling on the carriage rail 36 to the hoist 2.
2 is conveyed to a position in the vicinity. Thus, the components of the skeleton 10 to be assembled, the lifting rail 23, and the like can be transported, and the hoist 22 itself can be dedicated to the assembling work of the skeleton 10. Therefore, the utilization efficiency of the lifting machine 22 can be increased, and the construction can be performed efficiently. Moreover, materials and the like can be unloaded from a specific position (the end of the trolley rail 36), so that work can be performed smoothly even in a site where there is little space in the outer peripheral portion.

Also, the lifting machine traveling rail 23 of the lifting machine 22
Is installed on the beam 12 directly below the floor.
The load of the hoisting machine 22 is not applied on the concrete of No. 3 at all, and it is possible to prevent the concrete on the floor 13 from cracking due to the use of the hoisting device 20.

Further, the base member 32 is provided on the lower surface of the receiving member 30 for receiving the outrigger 26, and even if the receiving member 30 is bent by the load of the hoisting machine 22,
It is possible to prevent the concrete surface from cracking or the like without contacting the upper surface of the floor 13 of the immediately lower floor already constructed.

In addition, the lifting device running rail 23 and the bogie rail 36 of the transfer device 21 are similarly configured to support the load on the beam 12 on the immediately lower floor. Cracks and the like can be prevented.

In the method of constructing the skeleton 10, the construction method of laminating the skeleton 10 from the lower layer to the upper layer as described above is adopted. Therefore, the lifting device 20 and the transfer device 21 are used in this method. By applying the construction method used, construction can be performed more effectively.

In the above embodiment, the object to which the present invention is applied may be any building, and there is no intention to limit its shape and floor height.

In the above embodiment, the transfer device 2
Although two sets of 1 are used, it is needless to say that only one set may be used. In addition, a plurality of sets of the lifting system including the lifting device 20 and the transfer device 21 as described above may be used in parallel. Further, there is no intention to limit the configuration of the hoist 22 itself, the number of hoist running rails 23 to be used, and the like. The same applies to the transport carriage 35 and the like.

In addition, the hoist lifting rail 23, the receiving member 30, and the bogie traveling rail 36 have the base members 29, 32,
(Not shown), but regarding this,
The lifting rail 23, the receiving member 30, and the bogie traveling rail 36 may be integrated in advance, and may be re-arranged at the same time, or may be separately and independently provided.

Further, while moving the hoisting machine 22 from one end of the construction floor to the other end side, the truck rail 36 is laid.
After that, the structure 10 is constructed while the lifting machine 22 is retracted. However, the gist of the present invention is to construct the body 10 while moving the lifting machine 22 on the construction floor. It may be laid by another lifting machine or the like from the outer peripheral side of 10.

Other than this, any configuration may be adopted as long as it does not depart from the gist of the present invention, and it goes without saying that the above-mentioned configurations may be appropriately selectively combined. No.
