CONSTITUTION:The highest story of the multistoried structure is assembled and this is made to the working story 1 where various working devices for assembling and lifting devices 2 are arranged. Further, the lifting devices 2 lift the working story 1. Traveling rails 3 and 3 are provided around the working story 1 and the lifting members 5 to which the articulated welding robots 4 are fitted are supported on both rails 3. At the time of assembling, the working story 1 is first arranged on the foundation 12 and the legs 2a of the lifting devices 2 are extended and the working story 1 is maintained at the specified height. The frames 13 of a first story part are then arranged to the lower part of the working story 1 and the lower ends thereof are fixed on the foundation 12. At this time, the joining ends of the frames 13 are welded automatically by the welding robots 4. The frames of second and subsequent upper store parts are assembled in the same way hereafter.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for welding steel frames in high-rise structures.

BACKGROUND ART Conventionally, when building steel frames for high-rise structures, such as high-rise buildings, the frames are sequentially lifted upward by a tower crane, and the frames are aligned and assembled using skilled workers. . According to this construction method, the positioning and assembly of the framework is done manually, so there is a problem in that it takes time to construct the structure and work cannot be done in strong winds and rain, which affects the construction period. . As a way to prevent this, it is possible to install work equipment such as cranes, create a work floor that can secure a large space for safety, and finally use this work floor as the top floor of the structure. It will be done.

Problems to be Solved by the Invention By the way, even in the case where a working floor is provided and the lower floors are assembled one after another as described above, welding between the frames is still done manually, which takes time and requires a lot of welding. It is necessary to move the machine to the next assembly floor every time the work on that floor is completed, which creates a problem that the work becomes extremely troublesome.

Means for Solving the Problems In order to solve the above problems, the present invention provides a welding apparatus for steel frames for high-rise structures, in which the frame is assembled to be the second-most floor of the high-rise structure, and the frame is assembled to the second floor of the high-rise structure. A traveling rail is provided on the working floor where the work equipment for assembling the floor frame is arranged, and an elevating member that can run freely on the traveling rail and can be raised and lowered is provided, and this elevating member is welded with multiple joints. It is equipped with a robot.

Function According to the above configuration, the welding robot that welds the framework of each layer when constructing a high-rise structure is attached to the lifting member placed on the working floor, which is the top floor of the structure. Since the welding machine is raised by 1 at the same time as the welding machine, there is no need to lift the welding machine each time.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

The welding device according to the present invention, when constructing a high-rise structure,
It is pre-assembled as the top floor and is installed on a working floor where various assembly work devices such as cranes are arranged, and this working floor is used to sequentially assemble the skeleton shrine.

That is, in FIGS. 1 and 2, numeral 1 is a working floor that is assembled as the top floor of a high-rise structure, and in which various assembly work devices and lifting devices 2 are arranged. Note that the lifting device 2 is for raising and lowering the work floor 1 itself. '' Traveling rails 3 are provided around the two-legged work floor 1, for example above and below both left and right sides. Both rails 3 support an elevating member 5 having an articulated welding robot 4 attached to its lower end. For example, as shown on the right side of FIG. 1, this elevating member 5 includes a traveling truck 7 that can freely travel on a traveling rail 3'2 via driving wheels 6, and a rack and pinion mechanism 8 connected to the traveling truck 7. or as shown on the left side of FIG.
As shown in FIG.
A multistage telescopic rod 11 provided with 0 may be used.

When assembling a high-rise structure using the working floor 1, first place the working floor 1 on the foundation 12, and extend the legs 2a of the lifting device 2 provided on the working floor 1.
After this working floor 1 is maintained at a predetermined height, the framework 13 of the first floor part is placed in the lower part of this working floor 1, and its lower end is fixed to the foundation 12 side. At this time, the welding robot 4 automatically welds the joint ends of the frames 13 adjacent to each other, for example, the flanges of the horizontal beam members 14 as shown in FIGS. 3 and 4. Of course, the welding robot 4 is guided to each welding position via the elevating member 5.

When the first floor part is assembled, the lifting device 2 is used again to raise the working floor 1, and then the frame 15 of the second floor part is placed. The welding of each frame 15 in the two-story section from the second floor is performed not only with welding between frames 15 on the same floor, but also with frames 13 one floor below that floor. That is, as shown in FIGS. 5 and 6, the pillar portions 16 are also welded together. In this way, when a structure of a predetermined height is assembled, the working floor 1 is used as the top floor. Of course, at the end, the various 5 working devices and devices such as the welding robot 4 are disassembled and lowered to the ground using a winch device or the like.

Effects of the Invention According to the structure of the present invention as described in 2., a welding robot that welds the frames of each layer when constructing a high-rise structure is connected to a lifting member placed on the working floor that is the top floor of the structure. Since the welding robot is mounted on the floor, the welding robot is raised together with the work floor, so there is no need to lift the welding machine each time as in the conventional case, and assembly work can therefore be performed very easily.
