Description: TECHNICAL FIELD The present invention relates to a mounting bracket for a scooper with a base for mounting a scooter with a base used for assembling a steel frame structure, etc. It is fixed to the side wall to prevent side movement, displacement, and falling, and to be easily attached.

(Prior Art) Conventionally, in an assembly work of a steel frame structure, a column base made by cutting column steel having a quadrangular cross section is arranged, and a joint block is welded to the column base.

Then, brackets for attaching beams are attached to two or four sides of the joint block.

In such work, a so-called square with a base (right angle ruler) is used in order to make a right angle of the bracket with respect to the central axis of the column.

By the way, when mounting this scooper with stand on the upper surface of the column base, it is possible to install the scooper with stand in a stable state. The staff had to support this, and the work was complicated.

Therefore, a configuration is considered in which a magnet is built in the scooper with a base, and the scooper with a base is fixed to the side surface of the column base by the attraction force of this magnet.

This will be described with reference to FIG. A joint block 103 is welded to a column base 101 that is linearly joined in the central axis direction of the column. Brackets 105, 107 and 109 are welded to the three sides of the joint block 103.

Therefore, first, the three scoopers 111 with a base are fixed to the three sides of the column base 101. The table-equipped scooter 111 has a built-in magnet 113, and the table-equipped scooter 111 is fixed to a predetermined position of the column base 101 by the attraction force of the magnet 113.

Then, for example, when the bracket 107 is welded to the joint block 103, the bracket 107 is first applied to a predetermined position on the upper surface of the joint bracket 103. In that state,
At two positions of the bracket 107, the distances a and b between the reference surface 115 of the table-equipped square roller 111 and the surface 117 of the bracket 107 are measured.

Then, the bracket is set so that the distances a and b are equal.
The position of 107 is adjusted and temporarily attached to the joint bracket 103 by welding. Through the above work, the bracket 107 is attached in a state in which the right angle to the column base 101 is secured.

The other two brackets 105 and 109 are also attached to the joint bracket 103 by the same method.

(Problems to be Solved by the Invention) According to the above conventional configuration, there are the following problems.

As mentioned above, the magnet 113 is attached to
