The locking claw portion 3c provided on the connecting portion 3b is oriented so as to have a tip on one side in the longitudinal direction 1a and is inclined toward the lower surface 1b of the shaped steel 1. Specifically, the connecting portion 3b is provided with notches 3i on both sides (specifically, both sides in the longitudinal direction 1a), and the locking claw portion 3c has a triangular shape that narrows from the bottom surface of the notch 3i toward the tip. In addition, a plurality of protrusions are formed. The locking claw portions 3c and 3c on the respective sides of the connecting portion 3b face each other in the longitudinal direction 1a.

The articulated body 2 has an L-shaped cross section and is formed so as to extend in one direction. One piece 2e forming the L-shaped cross section forms a horizontal plane and the other piece forms an L-shaped cross section. 2f stands up from one piece 2e to form a vertical plane. Then, the articulated body 2 is arranged orthogonally to the upper surface 1d of the shaped steel 1. Therefore, a part of the lower surface of the one piece 2e of the articulated body 2 becomes the contact surface 2b that abuts on the upper surface 1d of the shaped steel 1 described above. Then, in the one piece 2e of the articulated body 2, a plurality of holes 2 g (in the illustrated embodiment, elongated holes having the extending direction of the articulated body 2 as the longitudinal direction) are formed in the articulated body 2. They are regularly lined up in the extending direction. Further, the above-mentioned connected portion 2a is provided in one of the pieces 2e, and a hole 2g formed in the connected portion 2a (in the illustrated embodiment, a penetration extending in the arrangement direction of the pair of side walls 3a and 3a). The bolt 6 will pass through the hole). That is, the connected portion 2a is connected to the connecting portion 3e by a bolt 6 passing through the hole 2g (through hole) and the bolt insertion hole 3g of the mounting body 3 and a female screw 7 screwed into the bolt 6.

Next, the operation and effect of the mounting body 3, the mounting body device 4, and the suspension bolt installation structure 5 having the above configurations will be described. As shown in FIGS. 5 to 8, the convex portion 3d provided on the side wall 3a of the mounting body 3 is hooked on the hooked portion 1c of the shaped steel 1 from above, whereby the mounting body 3 is prevented from falling. The mounting body 3 is temporarily mounted on the shaped steel 1, and in this temporarily mounted state, the locking claw portion 3c provided on the connecting portion 3b connecting the pair of side walls 3a and 3a below the shaped steel 1 has a shape. It is in a position where the movement of the mounting body 3 is not restricted with respect to the lower surface 1b of the steel 1. Thereby, in this temporary mounting state, the mounting body 3 can be moved in the longitudinal direction 1a of the shaped 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 fastening the bolt 6 and the female screw 7 (that is, when the connecting portion 3b of the mounting body 3 is brought close to the shaped steel 1), the engagement is engaged. The clasp portion 3c is caught on the lower surface 1b of the shaped steel 1 (that is, is pressed against the lower surface 1b (outer surface) of the shaped steel 1 and is caught on the lower surface 1b (outer surface)), and the mounting body 3 is the shaped steel 1 The movement of the steel in the longitudinal direction 1a is restricted, so that the mounting body 3 is actually mounted on the shaped steel 1. That is, in the temporary mounting before the main mounting, the mounting body 3 can be moved in the longitudinal direction 1a of the shaped steel 1 to adjust its position while preventing the mounting body 3 from falling, and the bolt 6 and the female screw 7 can be adjusted. In the main mounting by fastening the shaped steel 1, the locking claw portion 3c hooked on the lower surface 1b of the shaped steel 1 can prevent the mounting body 3 from moving in the longitudinal direction 1a of the shaped steel 1. Further, by preventing the attachment body 3 from moving in this way, the attachment body 3, the connecting body 2, and the suspension bolt 8 can be firmly fixed to the shaped steel 1.

The present invention is not limited to the above-described embodiment, and various other modifications can be made. For example, although the articulated body 2 has extension portions 2c on both sides, the extension portion 2c may be provided on only one side, and a bolt suspension lower portion 2d may be formed on the extension portion 2c. Further, the bolt suspension lower portion 2d may be provided not only at one place but also at a plurality of places for the extension portion 2c on one side. Further, the connecting body 2 does not have the extension portion 2c, and the side wall 3a of the mounting body 3, the connecting portion 3b, or the connecting body 2 has a mounting portion for mounting the attached object, or the attached object thereof. The portion corresponding to the above may be provided from the beginning, whereby the attached object or the portion corresponding to the attached object can be firmly fixed to the shaped steel 1.

Further, as shown in FIG. 14, in the suspension bolt installation structure 5, a plurality of shaped steels 1 may be provided so as to be arranged in parallel positions. At this time, the connecting body 2 is bridged over the upper surfaces 1d and 1d of the shaped steels 1 and 1 arranged so as to be parallel to each other, and the mounting body 3 is attached to the connecting body 2 in each shaped steel 1 with a bolt 6 and a female screw. 7 (in the illustrated embodiment, the nut 701 having the female screw 7) is fastened to connect. Then, the suspension bolt 8 is suspended from the shaped steels 1 and 1 to the bolt suspension lower portion 2d of the articulated body 2. That is, the articulated body 2 has an extended portion 2c extending outward beyond between the connected portions 2a and 2a connected to each of the connecting portions 3e and 3e of one mounting body 3, and the extending portion thereof. The bolt suspension lower part 2d will be provided in 2c. Further, the bolt suspension lower portion 2d may be provided not only at one place but also at a plurality of places as in the above-mentioned example.

Further, in the temporary mounting in which the convex portion 3d of the mounting body 3 is hooked on the hooked portion 1c of the shaped steel 1, the locking claw portion 3c is the mounting body 3 in the longitudinal direction 1a with respect to the lower surface 1b of the shaped steel 1. It suffices if it is in a position that does not restrict its own movement (that is, a position that allows movement), and the locking claw portion 3c hinders the movement of the mounting 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 they may be separated without contact with each other.

Further, although the locking claw portion 3c is inclined toward the lower surface 1b of the shaped steel 1, it may stand up toward the lower surface 1b of the shaped steel 1. Further, the locking claw portion 3c may be hooked on 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 screw 7 are fastened. It may be spread out and caught on the lower surface 1b of the shaped steel 1.

Further, the shaped steel 1 is made of a shaped steel having a substantially C-shaped cross section, and the shaped steel is not limited to the lip channel steel and may be a channel steel (channel steel). Further, the shaped steel 1 may not be made of a shaped steel having a substantially C-shaped cross section, but may be made of a shaped steel having another cross-sectional shape, for example, a shaped steel such as a joist steel (eye beam Joston).

Further, the mounting body 3 is temporarily mounted by the convex portion 3d being hooked on the hooked portion 1c of the shaped steel 1 from above, but as shown in FIGS. 15 to 17, the mounting body 3 is inverted. , The mounting body may be mounted on the shaped steel 1 so that the connecting portion 3b (specifically, the locking claw portion 3c provided on the connecting portion 3b) is placed on the upper surface 1d of the shaped steel 1. However, the mounting body 3 is attached to the shaped steel 1 by being installed so that the longitudinal direction 1a does not face the horizontal direction but faces the vertical direction or is installed so as to be inclined. May be good. In this case, the connecting body 2 is applied to the outer surface of the shaped steel 1 (lower surface 1b in the illustrated embodiment) so that the mounting body 3 and the connecting body 2 surround the shaped steel 1, and the bolt 6 and the female screw 7 are attached. (In the illustrated embodiment, the nut 701 having the female screw 7) is fastened so that the shaped steel 1 is sandwiched between the mounting body 3 and the connecting body 2, and the mounting body 3 is attached to the shaped steel 1 together with the connecting body 2. .. That is, the mounting body 3 connects the pair of side walls 3a and 3a arranged so as to sandwich the shaped steel 1 on the left and right orthogonal to the longitudinal direction of the shaped steel 1 and the base ends of the pair of side walls 3a and 3a. It is provided with a connecting portion 3b. The connecting portion 3b is provided with a locking claw portion 3c that is pressed against the outer surface of the shaped steel 1 and hooked on the outer surface so as to restrict the movement of the mounting body 3 itself with respect to the shaped steel 1 in the longitudinal direction 1a. The connecting body 2 is arranged so as to face the connecting portion 3b of the mounting body 3 with the shaped steel 1 in between, but is connected to each tip side of the pair of side walls 3a and 3a of the mounting body 3. A connecting portion 3e is provided to the body 2 so that the connecting portion 3b is brought close to the shaped steel 1 by fastening the bolt 6 and the female screw 7. Therefore, by fastening the bolt 6 and the female screw 7, the connecting portion 3b is close to the shaped steel 1, and the locking claw portion 3c is pressed against the outer surface of the shaped steel 1 and is caught on the outer surface of the mounting body 3 itself. The movement in the longitudinal direction 1a is restricted.

In this way, when the connecting portion 3b of the mounting body 3 is brought close to the shaped steel 1 by fastening the bolt 6 and the female screw 7, the locking claw portion 3c is pressed against the outer surface of the shaped steel 1 and is caught on the outer surface thereof. The mounting body 3 is restricted from moving in the longitudinal direction 1a of the shaped steel 1, and the mounting body 3 is actually mounted on the shaped steel 1. In the state where the bolt 6 and the female screw portion 7 are temporarily fastened (that is, in a loosely screwed state) before the main mounting, the pressure contact of the locking claw portion 3c to the shaped steel 1 is weak 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 shaped steel 1 to adjust its position. That is, before the main mounting, the mounting body 3 can be moved in the longitudinal direction 1a of the shaped steel 1 to adjust its position, and in the main mounting by fastening the bolt 6 and the female screw 7, it is caught in the shaped steel 1. The claw portion 3c can prevent the attachment 3 from moving in the longitudinal direction 1a of the shaped steel 1. Then, by blocking the movement of the mounting body 3, the mounting body 3, the connecting body 2, and the suspension bolt 8 can be firmly fixed to the shaped steel 1. Further, in this embodiment, the convex portion 3d provided on the side wall 3a of the mounting body 3 or the hooked portion 1c of the shaped steel 1 is not always necessary, but instead of the convex portion 3d or the above. 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 to contribute to simple movement prevention of the mounting body 3. You may let me.

Further, in FIGS. 15 to 17, lip channel steel is used as the articulated body 2, and the lip channel steel is arranged so that the groove 2h faces downward. Then, in fastening the bolt 6 and the female screw 7, the backing plate 10 is addressed to the lip portion 2i of the articulated body 2 made of lip channel steel.

Further, the articulated body 2 is made of a member having an L-shaped cross section, or is made of lip channel steel or channel steel, and the shape thereof is not particularly limited.
