Below, the procedure for attaching this attachment member 1 to the structural member 4, which is a C-shaped steel with a lip groove, will be explained based on the example shown in FIG.
In advance, the upper member 3A and lower member 3B of the above structure are welded together to form the main body 3, and the main body 3 is fastened to the fixing member 2 using fastening means (bolt rod 2A and nut 2B). Let's connect.

First, in FIG. 5(a), the mounting member 1 is laid down approximately 90 degrees to face the space 23 with respect to the downward facing piece 411 of the structural member 4, and is inserted by lifting it approximately vertically from the bottom to the top. It is arranged in a shape.
Next, in FIG. 5(b), the mounting member 1 is rotated while the downward piece 411 is maintained in the space 23, and FIG. 5(c), FIG. 5(d), and FIG. 5(e) are rotated in order. ) and FIG. 5(f), but this rotation is possible because the space 23 has a wide width with respect to the L-shaped upper flange 41 and the downward facing piece 411. This is because not only the horizontal groove 23a and the vertical groove 23b are combined, but also the intersection thereof is cut out.
5(a) to 5(f) all correspond to the first step of rotating the structural member 4 so that the upper flange 41 and the downward lip 411 face the space 23 of the fixing member 2. .
FIG. 5(g) shows a second step in which the mounting member 1 is rotated until it is placed on the upper flange 41, and the engaging portion 351 formed on the lower member 3B is engaged with the corner portion. and the subsequent third step.
That is, by tightening the nut 2B, the fixing member 2 rises as if being pulled up, the abutment part 24 engages the back surface of the upper flange 41, and conversely, the lower end 34 of the leg part 33 of the lower member 3B is pulled downward. It is pressed down and attached to the surface of the upper flange 41.

As mentioned above, FIG. 5(g) shows a state in which the second step and the third step are performed continuously, but the state before the third step is shown in FIG. Shown in (a) and (b).
That is, in FIGS. 2(a) and 2(b), the mounting member 1 is placed on the upper flange 41 and the engaging portion 351 is engaged with the corner, but the tightening of the nut 2B in the third step has not been done.
In this state, the fastening means (bolt rods 2A and nuts 2B) are not acting on the mounting member 1, so the mounting member 1 is merely placed on the upper flange 41 by its own weight, and for example, If the diameters of 21h and 31h are large, the bolt rod 2A and nut 2B can be moved up and down manually.
When the nut 2B is tightened in the third step from this state, the lower end (head) of the bolt rod 2A is pulled up until it comes into contact with the back surface of the upper surface part 21 of the fixing member 2, and the contact part 24 is attached to the upper flange. At the same time, the lower end 34 of the leg part 33 of the lower member 3B is pushed down and pressed against the surface of the upper flange 41 to attach it.

In this way, the mounting member 1 of the present invention is mounted without welding, specifically by fastening means, so construction noise is quiet even late at night, there is no fear of flying sparks, and it is designed with consideration for nearby residents. It is a construction method.
In addition, the worker can carry the mounting member 1 (fixing member 2 + main body 3), which is substantially one part, which has been assembled in advance with the fastening means (bolt rod 2A + nut 2B) onto the structural member 4 and work on it. Therefore, the workability is extremely superior compared to the prior art (Patent Document 1), which requires bringing in a plurality of members.

The exterior structure constructed in this way uses the above-mentioned mounting member 1, so the construction period is short, and since it is installed without welding, the construction noise is quiet and there is no risk of flying sparks, and there is no noise even late at night. This was done in consideration of nearby residents who are concerned about fires, fires, etc.
