Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting an outer wall by a moving lifter which is suitable for high-place work in steel frame erection work, and a device therefor.

[0002]

2. Description of the Related Art Conventionally, the outer wall mounting work after the framing of steel frame construction has been done by building a temporary fixed scaffold around the frame and working on the unstable narrow scaffold. The unloading of materials was also inconvenient, and the amount of unloading was limited once.

[0003]

Since the conventional work for mounting the outer wall on the narrow temporary scaffold is performed at a high place where the outer wall surface is wide,
There was a certain risk and a disadvantage in terms of efficiency. In particular, since it is a work in a narrow place that depends on human hands, in concrete construction work, two people lift the material and press it against the construction surface and hold it down, and another person will tighten it, at least. It required three workers, was very dangerous, and was very inefficient.

[0004]

SUMMARY OF THE INVENTION The present invention is a construction method for making a dangerous and inefficient outer wall mounting work on a narrow temporary scaffolding safe and efficient by one worker. Instead of a temporary scaffold, a lifter that can be moved up and down freely can be moved on the rail.A workbed on a relatively wide lifter is used to stockpile outer wall materials with a material supply conveyor, and in a three-dimensional direction with a button switch. It is characterized in that the outer wall material is adsorbed by an adsorption base that rotates 90 degrees and has a hinge mechanism that is rotatable, and the outer wall material is pressed against the construction surface to be held, and tightened by one worker.

The movable lifter is provided with a work table having a hydraulically movable frame along with a temporary table having a roller conveyor arranged on a frame frame which is self-propelled on a rail so as to be vertically movable. The present invention is characterized by a structure in which a two-arm hinge device that rotates and a suction frame that is connected to the tip of the two-arm hinge device and that can convert an angle of 90 degrees from horizontal to vertical are provided.

[0006]

The present invention proposes a construction method capable of safely and efficiently using mechanical power to mount a wide range of wall material on the outer wall surface in a high steel construction work on a stable work floor. When constructing the outer wall of the steel frame that has been assembled and assembled, rails are laid along the outer wall of the construction surface, and the frame that rolls on this is operated by remote control on the workbench to move to the construction surface, and hydraulic pressure is applied. First, position the work floor that raises the free frame by the same height as the temporary stand and unload it on the temporary stand beforehand.Move the wall material onto the work floor with the roller conveyor, and then re-install the work floor. To the position of
This time, by driving the two-arm hinge, the four suction cups of the suction frame made horizontal make it suck the wall material, and then the button switch changes the angle of the suction frame 90 degrees to make the wall material vertical. It is pressed against the outer wall construction surface, and the position is adjusted so that the workers can install it.

That is, the movement of the work frame to the construction site by operating the flexible frame, the loading of the wall material, the suction and removal, the pressing on the construction surface, etc. are all machine work by the remote control switch, and Only fixed installation work is done manually by workers, it is extremely safe and efficient, and the work floor that serves as a scaffold is relatively wide.Unlike conventional unstable temporary scaffolds, it is removable but stable and robust. Since it is a work floor, the worker has free work behavior using both hands on a safe floor surface, which is similar to that on the ground where the height is not felt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a work platform 6 having a temporary placing table 4 on which a roller conveyor 3 is arranged and a hydraulically actuable universal frame 5 is mounted on a frame platform 2 on which wheels are suspended so that they can run on rails 1 and 1. It is installed so that it can be lifted up and down, and a two-arm hinge device 7 that can be moved vertically and horizontally 360 degrees horizontally with a button switch is installed on the work floor 6, and the tip of the forearm 8 is driven from a horizontal position by a motor drive. A suction frame 9 for converting 90 degrees vertically is installed, and a movable lifter device having four suction cups 10 attached to four corners of the lower surface of the suction frame 9 is used as a construction jig and placed on the work floor 6. It is characterized by a construction method that enables the worker to safely install the outer wall of the steel frame 11 even if the worker alone. The work floor and the temporary stand are provided with safety handrails in three directions, leaving the work surface, and a prime mover 12 is installed as a power source if necessary.

The worker on the work floor 6 first operates the remote control switch to cause the frame base 2 to move to the position directly below the construction site, and then hydraulically operates the free frame 5 to extend the work floor 6. Raise and stop at the floor height position of the temporary placing table 4 at first, and bring the work floor surface and the temporary placing table floor surface into contact with the same plane. Here, after the wall covering material that has been unloaded on the temporary table is transferred to the working floor surface by using the roller conveyor 3, the free frame is further operated to move the working floor up to the construction site of the wall mounting surface. Raise and stop. At the construction site, operate the button switch to 2
The arm hinge device 7 is rotated to move up and down, and the suction frame 9 which is held horizontally with the suction cup facing downward is first pushed down to adsorb the wall material 13 with the suction cup and lifted to rotate the suction disc 90 degrees. , Vertical wall material and press along the steel construction surface

Since all of this is due to the operation of the two-arm hinge device by button operation, no special force of the worker is required, and one worker can efficiently and easily perform the work on a relatively wide and sturdy work floor. It is extremely safe work because it is work of. Since the wall material is pressed against the construction surface and is not held, there is no need to support the material. Therefore, it is extremely safe for the worker to open the both hands and perform work such as tightening the nuts without unsafe actions. By the self-propelled movement of the frame base, the expansion and contraction of the free frame, and the two-arm hinge device, the work floor can be moved to a wide range of construction positions on the construction surface, and the operation of the two-arm hinge device is extremely efficient.

[0011]

The outer wall mounting work by the moving lifter device of the present invention is carried out at a high place of the steel frame construction work.
Since it is a work on a sturdy work floor that is always located at the construction site, it is safe and has good workability. Moreover, since the work is performed by the operation of the two-arm hinge device, the number of personnel can be one, especially not an expert. Both have the effect that they can be constructed efficiently.
