Next, the effects of the mounting body 3, the mounting body device 4, and the hanging bolt installation structure 5 having the above configurations will be explained. As shown in FIGS. 5 to 8, the convex portion 3d provided on the side wall 3a of the mounting body 3 hangs onto the hooked portion 1c of the shaped steel 1 from above, thereby preventing the mounting body 3 from falling. This mounting body 3 is temporarily attached to the shaped steel 1, and in this temporarily attached state, the locking claw portion 3c provided on the connecting portion 3b connecting the pair of side walls 3a, 3a below the shaped steel 1 is fixed to the shaped steel 1. It is in a position where the movement of the mounting body 3 with respect to the lower surface 1b of the steel 1 is not restricted. Thereby, in this temporarily attached state, the attachment body 3 can be moved in the longitudinal direction 1a of the section steel 1 and its position can be adjusted. Then, as shown in FIGS. 9 to 12, when the mounting body 3 is pulled up by tightening the bolt 6 and the female thread 7 (that is, when the connecting portion 3b of the mounting body 3 is brought close to the section steel 1), it is engaged. The retaining claw portion 3c is caught on the lower surface 1b of the shaped steel 1 (that is, it is pressed against the lower surface 1b (outer surface) of the shaped steel 1 and caught on the lower surface 1b (outer surface)), and the mounting body 3 is attached to the shaped steel 1. Movement in the longitudinal direction 1a is restricted, and therefore, this mounting body 3 is permanently mounted to the section steel 1. That is, in the temporary installation before the actual installation, the mounting body 3 can be moved in the longitudinal direction 1a of the section steel 1 and its position can be adjusted while preventing the mounting body 3 from falling. In the actual installation by fastening, the movement of the mounting body 3 in the longitudinal direction 1a of the shaped steel 1 can be prevented by the locking claw portion 3c hooked on the lower surface 1b of the shaped steel 1. Moreover, by preventing the movement of the attachment body 3 in this way, the attachment body 3 and the connecting body 2, as well as the hanging bolt 8, can be firmly fixed to the section steel 1.

Note that the present invention is not limited to the embodiments described above, and various other changes are possible. For example, the connecting body 2 has the extension portions 2c on both sides, but may have the extension portions 2c only on one side, and the bolt hanging portion 2d may be formed on the extension portion 2c. Further, the bolt hanging portion 2d may be provided not only at one location but also at multiple locations on the extension portion 2c on one side. In addition, the connecting body 2 does not have the extension part 2c, but the side wall 3a or the connecting part 3b of the attaching body 3, or the connecting body 2 has a mounting part to which an object is attached, or the object to be attached It may have a portion corresponding to the object from the beginning, and thereby the object to be attached or the portion corresponding to the object to be attached can be securely fixed to the section steel 1.

Moreover, as shown in FIG. 14, in the suspension bolt installation structure 5, a plurality of section steels 1 may be provided in parallel positions. At this time, the connecting body 2 is bridged over the upper surfaces 1d, 1d of the shaped steels 1, 1 arranged in parallel, and the mounting body 3 is attached to the connecting body 2 in each shaped steel 1 with a bolt 6 and a female thread. 7 (in the illustrated embodiment, a nut 701 having a female thread 7). The suspension bolt 8 is suspended from the bolt suspension portion 2d of the connecting body 2 between the shaped steels 1 and 1. That is, the connecting body 2 has an extension part 2c that extends outward beyond the connected parts 2a, 2a connected to each other in correspondence with the connecting parts 3e, 3e of one attachment body 3, and 2c is provided with a bolt hanging portion 2d. Further, the bolt hanging portion 2d may be provided not only at one location but also at multiple locations, similar to the above-described example.

It is sufficient that the attachment member 3 is in a position where its own movement is not restricted (that is, a position where movement is permitted), and the locking claw portion 3c prevents the movement of the attachment body 3 itself with respect to the lower surface 1b of the shaped steel 1. They may be in contact with each other to the extent that they are not in contact with each other, or may be separated without contacting each other.

Further, although the locking claw portion 3c is inclined toward the lower surface 1b of the shaped steel 1, it may be erected toward the lower surface 1b of the shaped steel 1. Further, the locking claw portion 3c may be hooked onto the lower surface 1b of the shaped steel 1 while maintaining the shape of the locking claw portion 3c when the bolt 6 and the female thread 7 are fastened. It may be something that is caught on the lower surface 1b of the section steel 1 while being pushed out.

Further, although the shaped steel 1 is made of a shaped steel having a substantially C-shaped cross section, this shaped steel is not limited to a lip channel steel, but may be a channel steel. Further, the section steel 1 does not have to be a section steel having a substantially C-shaped cross section, but may be a section steel having another cross-sectional shape, such as a joist steel (I-beam joston).

Furthermore, the attachment body 3 is temporarily attached by the convex portion 3d hanging onto the hooked portion 1c of the section steel 1 from above, but as shown in FIGS. 15 to 17, this attachment body 3 is reversed. , the attachment body may be attached to the shaped steel 1 so that the connecting portion 3b (specifically, the locking claw portion 3c provided on the connecting portion 3b) rests on the upper surface 1d of the shaped steel 1, or the attachment body may be attached to the shaped steel 1. However, the mounting body 3 is attached to the shaped steel 1 because the longitudinal direction 1a is not facing the horizontal direction but is installed so as to face the vertical direction, or is installed so as to be inclined. Good too. In this case, the connecting body 2 is attached to the outer surface (in the illustrated embodiment, the lower surface 1b) of the shaped steel 1 so that the attachment body 3 and the connecting body 2 surround the shaped steel 1, and the bolt 6 and the female thread 7 By fastening a nut 701 having a female thread 7 in the illustrated embodiment, the attachment body 3 is attached to the section steel 1 together with the connection body 2 so that the section steel 1 is sandwiched between the attachment body 3 and the connection body 2. . That is, the attachment body 3 connects the shaped steel 1 to a pair of side walls 3a, 3a arranged to sandwich the shaped steel 1 on the left and right sides perpendicular to the longitudinal direction of the shaped steel 1, and the base ends of the pair of side walls 3a, 3a. A connecting portion 3b is provided. This connecting portion 3b is provided with a locking claw portion 3c that is pressed against and hooked onto the outer surface of the shaped steel 1 so as to restrict movement of the attachment body 3 itself in the longitudinal direction 1a relative to the shaped steel 1. The connecting body 2 is arranged to face the connecting part 3b of the attachment body 3 with the shaped steel 1 in between, but there is A connecting portion 3e is provided to the body 2, which is connected by fastening a bolt 6 and a female thread 7 so that the connecting portion 3b approaches the section steel 1. Therefore, by fastening the bolt 6 and the female thread 7, the connecting part 3b approaches the shaped steel 1, and the locking claw part 3c is pressed against the outer surface of the shaped steel 1 and is caught on the outer surface of the shaped steel 1. Movement in the longitudinal direction 1a is restricted.

In this way, when the connecting part 3b of the mounting body 3 is brought close to the shaped steel 1 by fastening the bolt 6 and the female thread 7, the locking claw part 3c is pressed against the outer surface of the shaped steel 1 and caught on the outer surface. , the attachment body 3 is restricted from moving in the longitudinal direction 1a of the section steel 1, and this attachment body 3 is permanently attached to the section steel 1. In a state where the bolt 6 and the female threaded portion 7 are temporarily fastened (that is, loosely screwed together) before the actual installation, the locking claw portion 3c is pressed against the section steel 1 weakly, or there is no pressure contact. The mounting body 3 can be moved together with the connecting body 2 in the longitudinal direction 1a of the section steel 1 to adjust its position. That is, before the main installation, the mounting body 3 can be moved in the longitudinal direction 1a of the section steel 1 to adjust its position, and during the main installation by fastening the bolts 6 and female threads 7, the attachment that gets caught on the section steel 1 can be adjusted. The retaining claw portion 3c can prevent the mounting body 3 from moving in the longitudinal direction 1a of the shaped steel 1.

Further, in this embodiment, the protrusion 3d provided on the side wall 3a of the mounting body 3 and the hooked portion 1c of the section steel 1 are not necessarily required, but may be used in place of the protrusion 3d or in the In addition to the convex portion 3d, a convex portion that presses the outer surface of the shaped steel 1 is provided on the side wall 3a or the connecting portion 3b, and the convex portion acts so as to contribute to simply preventing movement of the mounting body 3. You may let them.

Furthermore, in FIGS. 15 to 17, a lip channel steel is used as the connecting body 2, and the lip channel steel is arranged so that its groove 2h faces downward. When the bolt 6 and the female thread 7 are fastened together, the caul plate 10 is applied to the lip portion 2i of the connecting body 2 made of lip channel steel.

Further, the connecting body 2 may be made of a member having an L-shaped cross section, or may be made of lip channel steel or channel steel, and its shape is not particularly limited. Further, the bolt suspension portion 2d may be formed by a groove extending in the direction in which the connecting body 2 extends, such as a groove in a lip channel steel, instead of the hole 2g, and the bolt suspension portion 2d may be formed by a groove extending in the direction in which the connecting body 2 extends, such as a groove in a lip channel steel. The suspension bolt 8 can be suspended at any position in the extending direction of the connecting body 2 by a stopper (not shown) arranged inside the section. Of course, even if the connecting body 2 is made of lip channel steel, the hanging bolt 8 may be suspended using a hole formed in the upper wall facing the lip portion.
