Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding device for mounting on a steel column of a building or the like for various work at a construction site.

[0002]

2. Description of the Related Art Conventionally, in a building under construction, when welding steel columns to be connected vertically, a scaffolding device having a substantially U-shaped plane is attached to the outer periphery of a lower column, and this scaffolding device is used. A worker rides on and works. Such a scaffolding device includes, for example, as shown in FIG. 6, a mounting piece composed of two main scaffolding plates 1 and 1 and an intermediate scaffolding plate 2, which are preliminarily vertically welded to both side surfaces of a pillar 3. Some of the hinge pipes 4 and 4 are provided with hinge pipes 5 that are pivotally supported.

When the scaffolding device is attached to a pillar, hinge pipes 5 and 5 which are vertically fixed to two main scaffolding plates 1 and 1 are attached to the mounting piece 4 on the floor side of the building. , 4 respectively,
After the through hole 4a of the mounting piece 4 and the pipe hole 5a of the hinge pipe 5 are aligned with each other, the vertical support pin 6 is inserted into both of them. On the other hand, the handrail 1 is attached to the sockets 14 fixed to the outer periphery of the main scaffolding plates 1 and 1 at appropriate intervals.
Insert and hold 5. In this way, the main scaffolding plates 1, 1 of the scaffolding device are rotatably held on the side surface of the pillar 3 on the floor side. In this state, the pillar 3 on the floor side
Welding work can be carried out on this scaffolding device.

Further, the pillar 3 is provided on the side opposite to the floor side.
In the case of performing the welding work of (1), the main scaffolding plates 1, 1 are rotated around the hinge pipes 5, 5 in the direction of the arrow in FIG. 6 and set at the positions shown by the solid lines. At this time, if there is a space between the main scaffolding plates 1 and 1 and it is dangerous, the intermediate scaffolding plate 2 is rotated through the hinge 2a, and the intermediate scaffolding plate 2 is bridged between the main scaffolding plates 1 and 1. The worker can freely cross over the main scaffolding plates 1, 1.

[0005]

However, in the above-mentioned conventional scaffolding device, two hinge pipes 5 pivotally supported by the mounting pieces 4 and 4 vertically welded to both side surfaces of the pillar 3 have two main hinge pipes. Since the scaffolding plates 1 and 1 are provided in the vertical direction, when the two main scaffolding plates 1 and 1 are rotatably held on the side surfaces of the columns 3, the through holes 4 are formed as described above.
Since the vertical support pin 6 must be inserted after the a is aligned with the pipe hole 5a, this alignment is extremely difficult because the alignment of the holes is between holes, and the vertical support pin 6 cannot be easily attached to the side surface of the pillar 3 of the scaffolding device. There was a problem that the mounting was not easy and quick.

Therefore, the present invention has been made for the purpose of solving the problems of the conventional scaffolding device.

[0007]

Therefore, according to the scaffolding device of the present invention, the first support pin 9 is fixed between the left and right mounting plates 8 and the second support pin 9 is arranged below the first support pin 9. The insertion holes 11, 11 of the support pin 10 are formed in the left and right mounting plates 8,
The mounting member 7 provided on the first supporting pin 9 of the mounting member 7 is rotatably mounted in advance on the supporting members 5 which are vertically fixed to the two main scaffolding plates 1 and 1, respectively.
To the locking grooves 17, 17 of the mounting pieces 4, 4 which are horizontally mounted on the side surface 3a of the pillar 3, and the left and right mounting plates 8,
The second support pin 10 is inserted into the insertion holes 11 and 11 of No. 8 and the insertion holes 18 and 18 provided in the mounting pieces 4 and 4, respectively.

[0008]

Since the scaffolding device of the present invention is provided with the above-mentioned means, it is only necessary to align the first support pin 9 and the engaging grooves 17, 17 with each other, which facilitates the alignment.
