DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting an outer wall plate at a predetermined position on an outer wall surface of a building efficiently using a robot when constructing an outer wall of a building under construction.

[0002]

2. Description of the Related Art Conventionally, when a PC plate is mounted on an outer wall of a building under construction, the PC plate is lifted one by one by a ground crane truck, transported to a predetermined position of a building frame, and worked on the building frame side. A worker goes up and installs the PC version.

[0003]

In a conventional work in which a PC version is lifted one by one by a crane truck on the ground and attached to a building frame by a worker, it takes time to operate the crane. It was dangerous work to go up to the building frame. For this reason, the installation of the PC plate requires a specialized expert, and it has been difficult to secure such personnel. Therefore, the present invention enables a robot to automatically attach a PC plate to an outer wall surface of a building so that the PC plate can be attached with high work efficiency.
The purpose is to reduce the danger to work.

[0004]

According to the present invention, in order to achieve the above object, an outer wall plate mounting robot is arranged on the roof of a building under construction, and a large number of PC plates are conveyed to the roof in a lump. Then, the grip portion of the robot grips the PC plate and lifts it by a winch operation to transfer the outer wall plate to a position above the outer wall surface of the building under construction. Next, the PC plate is lowered along the outer wall surface of the building under construction by the winch operation of the robot, and the outer wall plate is locked at a predetermined position by a locking metal provided on the outer wall frame of the building under construction. Thereafter, the grip portion is separated from the outer wall plate, and the PC plate is again transferred to a predetermined position by a robot and attached in the same manner as described above. In order to attach the outer wall slab to the latch on the building frame side, an inverted T-shaped engagement groove is provided on the inner surface of the outer wall slab so that the engagement groove does not fall out of the anchor due to the weight of the outer wall slab. Preferably.

[0005]

According to the above method of mounting the outer wall plate, the grip portion of the robot lifts the PC plate and lowers the PC plate to a predetermined position, and locks the PC plate with the locking bracket on the building frame side. Exterior wall version can be attached to the building exterior wall. In addition, in order to lock the outer wall plate to the locking member on the building frame side, an inverted T-shaped locking groove is provided on the outer wall plate side as shown in FIG. Then, the horizontal portion of the lock fitting enters the vertical portion of the locking groove so that the base portion of the locking fitting does not come off unless lifted against its own weight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.
Place the outer wall version mounting robot 1 on the roof of the building under construction,
The robot 1 can move along the guidance line 2 on the roof, and can move all around the rooftop near the outer wall. Also, a PC plate (outer wall plate) 3 for forming an outer wall on the roof of a building under construction is lifted at a time, and is stacked inside the guide wire 2 at appropriate intervals.

When attaching the PC plate 3 to the outer wall surface of the building under construction, the grip portion 1a of the robot 1 is engaged with the hook 3a projecting from the upper end of the PC plate 3, and the winch 4 provided on the robot 1 is provided. To lift the PC plate 3 via the grip portion 1a (see FIG. 3). In this embodiment, one PC plate is lifted by the two grip portions 1a. Next, the robot 1 turns the arm, and transfers the PC plate 3 to a position above the outer wall surface of the building under construction (see FIG. 4). Further, the winch 4 is operated to lower the PC plate 3 along the outer wall surface of the building, and the PC plate 3 is attached to the building frame 5 at a predetermined position (FIG. 5).
reference).

In mounting the PC plate 3, as shown in FIG. 6, inverted T-shaped engaging grooves 6 provided at four corners on the inner surface of the PC plate 3 are mounted on the building frame 5 at appropriate intervals. It is engaged with the locking hardware 7. That is, the horizontal portion 7 of the locking hardware 7
a enters from the horizontal portion of the engagement groove 6, and the base 7b of the locking hardware 7
Is inserted into the vertical portion of the engaging groove 6, the PC plate 3 does not come off the building frame 5 unless the PC plate 3 rises against its own weight. When the engagement groove 6 is engaged with the locking hardware 7, the operation is performed while operating the arm of the robot 1 back and forth, up and down. When the attachment of the PC plate 3 is completed, the grip portion 1a is moved to the PC.
Release the hook 3a of the plate 3, operate the winch 4 to raise the grip portion 1a, rotate the arm of the robot 1 about 180 °, lift the PC plate 3 with the grip portion 1a in the same manner as described above, and build Repeat the work of attaching to the predetermined position.

When the PC plate 3 is attached to the upper end of the outer wall of the building in this manner, the robot 1 moves along the guide line 2, and the PC plate 3 is attached to the outer wall of the next row in the same manner as described above. The PC version 3 is mounted on the outer wall of the entire building. When installing the PC version 3 on the outer wall of the building as described above,
The PC version is automatically installed by automatically controlling the movement, turning, gripping portion 1a, winch 4, etc. of the robot 1 using a computer or various sensors, but a part of the operation is performed by an operator. It may be.

[0010]

According to the method of mounting the outer wall plate of the present invention, the PC plate is lifted by the robot and transported to a predetermined position, and the PC plate is mounted on the locking bracket on the building frame side by the robot operation. However, it is not necessary to work at the mounting position of the PC plate, and the work can be performed safely and efficiently. Further, by automatically operating the robot, the PC plate can be automatically attached to the outer wall of the building.
