Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of constructing high-rise buildings, such as high-rise buildings.

Conventional Technology In the past, when constructing a high-rise building, the steel frame, exterior materials, etc. were carried upward one by one using a tower crane, and assembled by skilled workers.

Problems to be Solved by the Invention However, according to the above construction method, there was a problem in that because the assembly was done manually, the work could not be done on days with strong winds and rain, which affected the construction period. . Furthermore, even if the work could be carried out, there was a problem in that it was dangerous.

Therefore, an object of the present invention is to provide a method of constructing a high-rise building that can solve the above problems.

Means for Solving the Problems In order to solve the above problems, the method for constructing a high-rise building of the present invention is such that when assembling the high-rise building sequentially from the bottom to the top, the upper end of the structure that is being constructed is In this method, a temporary structure whose at least the top and all sides are covered with plates is supported, and steel frames, exterior materials, etc. are assembled using an overhead crane and an assembly robot placed inside the temporary structure.

Effects According to the construction method described above, the assembly of high-rise buildings is carried out within a temporary structure covered with plates, which eliminates construction delays and work risks caused by wind and rain, and also eliminates overhead traveling cranes and work robots. By using the above, it is possible to improve assembly accuracy and shorten the construction period.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 6.

First, the temporary structure used in this construction method will be explained based on FIGS. 1 to 4.

That is, this temporary structure 1 consists of a side frame 2 that is larger than the outer peripheral surface of a high-rise building (hereinafter simply referred to as a building) A by a predetermined width, and the entire upper surface of this side frame 2. A working frame body 5 consisting of an upper frame body 3 arranged and supported over the frame bodies 2 and 3, and a plate body (for example, a thin steel plate) 4 that covers the entire outer peripheral surface of each of these frames 2 and 3; It is comprised of a lifting device 6 that raises the frame 5 relative to the building A. In addition, in order to prevent objects from falling from the temporary structure 1, a plate 4 is also provided on the lower surface of the side frame 2. Further, as shown in FIG. 3, this lifting device 6 includes a lifting cylinder device (for example, a hydraulic cylinder) 7 suspended at multiple locations around the lower end 2a of the side frame 2, and a lifting cylinder device 7 (for example, a hydraulic cylinder) for lifting. A support member 8 supported at the tip of a rod 7a of the cylinder device 7 and an upper support bin 9 provided at the lower end 2a of the side frame 2 are inserted into an insertion hole 10 on the side of a building, that is, a structure B under construction. an upper locking cylinder device 11 (for example, a hydraulic cylinder) that moves the lower support bin 12 into and out of the insertion hole 10 on the structure B side; (for example, a hydraulic cylinder). In addition, in FIG. 3, 14 is a guide roller provided on the working frame 5 side and the support member 8 side.

Therefore, when raising the working frame 5 relative to the structure B, first pull out the upper support bin 9 with the upper and lower support pins 9 and 12 inserted into the insertion holes 10 on the structure B side. Next, after extending the rod 7a of the lifting cylinder device 7 and raising the working frame 5 relative to the structure B, the upper support pin 9 is inserted into the upper insertion hole 1 on the structure B side.
Just insert it within 0. When raising again, after pulling out the lower support bin 12 from the insertion hole 10,
The rod 7a of the ascending cylinder 7 may be retracted to insert the lower support bin 12 into the upper insertion hole 10, the upper support bin 9 may be pulled out again, and the rod 7a of the ascending cylinder 7 may be extended. By repeating this procedure, the working frame 5, that is, the entire temporary structure 1 can be raised in accordance with the assembly of the building AI).

Further, inside the working frame 5, that is, the upper frame 3, an overhead traveling crane 15 is provided as shown in FIG.
A plurality of robots 16 are disposed on the side frame 2, and a plurality of working robots 16 are disposed on the side frame 2, and are movable along the periphery of the building A. That is, as shown in FIG. 4, this working robot 16 includes a running cart 19 having running wheels 18 guided by a pair of upper and lower running rails 17 laid on the stepped portion 2b of the side frame 2; A manipulator 20 is provided on the upper part of this traveling trolley 19 and is used for various operations.
The robot body 21 has a robot main body 21.

Next, the building construction method will be explained.

First, as shown in Figure 5, after building the foundation C of the building,
A pedestal 22 is provided around it. Next, the working frame 5 is supported on this pedestal 22. That is, on the pedestal 22,
The lower block body 5A, which is the lower part of the side frame body 2 in which the working frame body 5 is made into blocks, is assembled using a truck crane or the like. Next, the intermediate block body 5B, which is the upper part of the side frame body 2 and the peripheral part of the upper frame body 3, which are also made into blocks, is assembled using a truck crane, and then the middle part of the upper frame body 3 is assembled. A certain upper block body 5
Assemble C in the same way. Then, during or after assembly, the overhead traveling crane 15 and the working robot 16 are arranged. Note that a demolition crane for dismantling the work frame 5 is mounted in a disassembled state at a suitable location of the work frame 5, for example near the end of the upper frame 3, and this demolition crane is mounted in a disassembled state. A small crane will also be installed to lower it to the ground. Next, a steel frame is constructed on the foundation C using an overhead traveling crane operator 5, a work robot 16, etc.
Assemble flooring, exterior materials, etc.

When the assembly to a predetermined height, for example one floor, is completed, the entire working frame 5 is raised using the lifting device 6, and the same work as above is repeated again to raise the building A one by one. Assemble it. Note that materials are carried in during the assembly process through an access hole provided in the structure B during the assembly process. After the assembly of the top layer is completed, the sixth
As shown in the figure, a demolition crane 23 is assembled on the upper surface of the working frame 5, and the upper block 5C of the upper frame 3 is disassembled and lowered to the ground by the demolition crane 23.

Then, the demolition crane 23 is disassembled and lowered onto the roof of building A using a small crane (not shown) installed in advance, and then the intermediate block body 5B and the lower block body 5A are lifted from the ground using a small crane. Finally, the small crane can be dismantled and lowered to the ground using the elevator already installed in Building A. Furthermore, Building A
During the assembly of the temporary structure 1, as shown in FIG. 1, support columns 24 are provided to support the temporary structure 1 to the building All, and when the temporary structure 1 is dismantled, as shown in FIG. A reinforcement 25 is provided.

In this way, the assembly work for building A is carried out inside the work frame 5, which eliminates construction delays and work risks caused by wind and rain, and also eliminates the need to use overhead traveling cranes 15, work robots 16, etc. Therefore, it is possible to improve assembly accuracy and shorten the construction period.

By the way, in the above embodiment, a cylinder device is used as the lifting device, but for example, a rack and pinion mechanism may be used.

Effects of the Invention As described above, according to the construction method of the present invention, the assembly of a high-rise building is carried out within a temporary structure covered with plates, which eliminates construction delays and work risks caused by wind and rain, and Because it uses an overhead traveling crane and a work robot, it is possible to improve assembly accuracy and shorten the construction period.
