2. Description of the Related Art For example, in a building such as a building, as shown in FIG. 13, the channel steel 1 is used as a beam or as a stand for an air conditioner outdoor unit installed on a rooftop.
On the flange 2 of the channel steel 1, a rack body 5 such as a cable rack or a refrigerant pipe rack, which is formed in a ladder shape, is formed by connecting parent girders 6, 6 facing in parallel to each other with a child girder 7. The cables are placed so as to intersect with each other and supported from below, and wiring of various cables and piping of refrigerant pipes are performed so as to extend between the sub-beams 7 of the rack body 5.

When the rack body 5 is supported on the grooved steel 1 in such a crossing state, when the rack body 5 moves in the longitudinal direction of the sub beam 7, the rack body 5 is moved with respect to the grooved steel 1. Since unreasonable force is applied to the cables and refrigerant tubes supported by
It is necessary to prevent lateral shake of the rack body 5 with respect to the channel steel 1.

Conventionally, in order to prevent the lateral deflection of the rack body 5, the flange 2 of the channel steel 1 and the main girder 6 of the rack body 5 are used.
A method of strongly sandwiching the intersections A and B of the lower edge with the edge plate 6a from the up and down direction has been adopted, and the following three methods have been used as this method.

In the first method, as shown in FIG. 14, a bolt hole 10 is formed in the flange 2 of the channel steel 1, and one end side of the strip plate 11 and the flange 2 of the channel steel 1 are provided. The lower surface of the flange 2 is obtained by inserting the bolt 3 into the bolt hole 11a provided at the other end of the strip 11 and the bolt hole 10 formed in the flange 2 with the lower edge plate 6a of the main girder 6 of the rack body 5 interposed therebetween. It is a method of tightening with the nut 4 from the side.

In the second method, as shown in FIG. 15, the flange 2 of the channel steel 1 is sandwiched between one end side of the substantially triangular upper plate 12 and the lower plate 13, and the parent girder is held at the other end side. With the edge plate 6a of No. 6 sandwiched, the bolt 3 is passed through the bolt hole 12a of the upper plate 12 and the bolt hole 13a of the lower plate 13, and the nut 4 is tightened from the lower surface side.

In the third method, as shown in FIG. 16, the edge plate 6a of the main beam 6 is sandwiched between one side edge of the strip plate 14 longer than the width of the flange 2 and the flange 2. , Bolt holes 14a provided at both ends of the strip plate 1,
4b is a method in which screw portions 15a and 15b of a square U-shaped bolt 15 straddling the channel steel 1 from below are passed through and tightened with nuts 4 and 4.

[0008]

However, in the above-mentioned first method, it is necessary to make a hole in the flange 2 of the channel steel 1, which requires a lot of work.

In the second method, since the thickness of the flange 2 of the channel steel 1 becomes smaller toward the tip, when the vibration or shock is applied, the upper plate 12 and the lower plate 13 are separated from each other by the flange 2. It slips off to the tip side of.

In the third method, a square U-shaped bolt that matches the size (flange width and height) of the channel steel 1 must be prepared, which complicates parts management. A space for passing the square U-shaped bolt 15 is required below 1.

The present invention solves these problems, can be easily installed, does not come off due to vibration or shock, can be applied to different shaped steels, and does not require a gap below the shaped steel. It is intended to provide a steady rest.

Then, the pressing plate was placed so as to overlap the edge plate of the lower edge of the rack body in a state of being in contact therewith, and the regulating plate was placed so as to abut on the end surface on the side opposite to the tip end of the flange of the shaped steel. In this state, it is connected to the lower metal fitting on the lower surface side of the flange of the shaped steel through the bolt inserted in the bolt hole, and the edge of the rack body is connected to the lower metal fitting by tightening the bolt. A rack body steady rest, wherein a plate and the shaped steel flange are sandwiched. 2. The rack steadying device according to claim 1, wherein the pressing plates of the upper metal fittings are provided on both side edges of the upper substrate, respectively. 3. A plurality of bolt holes in the upper metal fitting are provided in the length direction of the upper substrate at intervals substantially equal to the difference in length of flange widths of a plurality of types of shaped steel. The rack body steady rest according to claim 1. 4. The rack body steady rest according to claim 1, wherein the bolt holes of the upper fitting are formed as elongated holes along the length direction of the upper substrate. 5. The rack steadying device according to claim 1, wherein a protrusion that protrudes in a substantially arc shape is continuously provided in the width direction on the upper surface side of the upper fitting. 6. The rack body steady rest according to claim 1, wherein the bolt hole of the upper metal fitting is formed as a square hole which can restrict rotation thereof when a square root bolt is received as the bolt. Ingredient 7. The lower metal fitting includes a lower substrate having a substantially rectangular shape, a bolt hole formed in the lower substrate for passing the bolt, and an overlap of a bolt hole of the lower substrate from one end side of the lower substrate. And a second butting portion extending from the other end side of the substrate to the one surface side of the lower substrate. The tip side of the first butting portion of the lower substrate abuts the tip of the flange of the shaped steel and the lower surface of the edge plate of the rack body, and the tip side of the second butting portion is the shape The rack body runout according to claim 1, wherein the bolt inserted into the upper metal fitting in the installed state is received in the bolt hole of the lower substrate in a state of being in contact with the lower surface of the steel flange. Stop. 8. The rack steady rest according to claim 7, wherein two bolt holes of the lower metal fitting are provided along the width direction of the lower substrate. 9. The rack steadying device according to claim 7, wherein the bolt holes of the lower metal fitting are formed as elongated holes extending in the width direction of the lower substrate. 10. The bolt hole of the lower metal fitting has a threaded groove to be screwed into the bolt.
