DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.

In the figure, the support member 11 is installed on the left and right ends of a suspension bolt 7 suspended from a ceiling or the like. The support member 11 includes a bottom plate 12 and a pair of left and right side plates 1.
3 is a channel having a substantially U-shaped constant cross section. Further, elongated bolt notches 14 facing laterally are formed at both ends of the bottom plate 12, and a plurality of engaging holes 15 are formed along the bolt notches 14 at predetermined intervals.
Has been drilled. The engagement hole 15 corresponds to the engaged portion in the claims. As the engaged portion, instead of the engaging hole 15, a recessed portion may be formed without penetrating.

After the suspension bolt 7 is inserted into the bolt insertion notch 14 of the bottom plate 12 of the support member 11, the upper and lower nuts 8 of the suspension bolt 7 are tightened, and the bottom plate 12 is clamped by the upper washer 21 and the lower washer 22. Therefore, it is installed on the left and right suspension bolts 7. Here, the upper washer 21 and the lower washer 22 have a rectangular plate shape, and each has a through hole through which the suspension bolt 7 can be inserted at the center thereof. Further, a pair of engaging protrusions 23 are formed on both sides of the insertion hole of the lower washer 22 at positions facing each other by press working or the like, and the intervals between the engaging protrusions 23 are such that the supporting members 11 face each other. The engaging projections 23 are formed to have the same length as the gap between the fitting holes 15, so that the engaging projections 23 can be engaged with the arbitrary engaging holes 15 of the support member 11.

On the other hand, the receiver 1 is a ladder-like structure in which a child girder 3 is erected at a predetermined interval between a pair of left and right parent girders 2, and the receivers 1 are connected to each other by connecting fittings not shown. Are linked using. The receiving tool 1 is mounted on the supporting member 11 using a fixing fitting 4. The receiver 1 is
As shown in FIG. 3, an elongated flat plate nut 5 is screwed into a fixing screw 6 inserted into a mounting hole formed in the protruding plate 4a of the fixing bracket 4 and temporarily tightened to fix the plate nut 5 in the state. The support nut 11 is inserted through the opening 16a between the two flanges 16 and then the plate nut 5 is horizontally rotated in the support member 11 by approximately 90 degrees so that both ends thereof are engaged with the flange 16. , The supporting member 1 by screwing the fixing screws 6
It is attached to 1.

Next, a method of attaching the support member 11 to the suspension bolt 7 will be described with reference to FIGS. 4 and 5.

To attach the support member 11 to the suspension bolt 7,
The notch 14 for inserting the bolt of the support member 11 is inserted from the side of the suspension bolt 7 into which the upper washer 21, the lower washer 22, and the nut 8 have been previously inserted. At this time, as shown in FIG. 4, the bottom plate 12 of the support member 11 is inserted while holding the ends of the upper washer 21 and the lower washer 22 with fingers to widen between the facing surfaces on the other side. Therefore, the insertion work can be easily performed. Further, the support member 11 may be fitted to the suspension bolt 7 with the upper washer 21, the lower washer 22 and the upper and lower nuts 8 attached to the suspension bolt 7 in advance. When the lower nut 8 is mounted after being fitted into the suspension bolt 7, it is not necessary to hold the support material 11 with one hand so that the support material 11 does not drop. Next, the engagement protrusion 23 of the lower washer 22 is engaged with the optimum engagement hole 15 in accordance with the interval between the left and right suspension bolts 7. As a result, the support member 11 is prevented from moving outward and coming off the hanging bolt 7. Therefore, it can be said that the engagement protrusion 23 of the lower washer 22 corresponds to the position shift prevention device in the claims. Further, the pair of engaging projections 23 of the lower washer 22 are engaged with the engaging holes 15 of the support member 11 to prevent the bolt insertion notch 14 from expanding and deforming left and right. Therefore, it can be said that the engagement convex portion 23 of the lower washer 22 corresponds to the deformation preventing tool in the claims.

As described above, in the support member for the wiring / piping material of this embodiment, the elongated bolt notches 14 into which the hanging bolts 7 can be inserted from the sides are provided on both sides of the bottom plate 12. The bolt insertion notch 14 is provided with the engagement hole 15 as an engaged portion with which the lower washer 22 provided with the engagement protrusion 23 that is a position shift prevention tool and a deformation prevention tool engages.
It is provided on the periphery of.

Accordingly, the notch 14 for inserting the bolt is inserted from the side of the support member 11 toward the hanging bolt 7, and the ends of the upper washer 21 and the lower washer 22 are grasped with fingers and the other side is expanded. After opening the bottom plate 12 of the support material while opening, the engagement convex portion 23 of the lower washer 22 is engaged with the engagement hole 15, and the support material 11 is moved to the left and right by a simple operation of tightening the nut 8. It can be installed between the suspension bolts 7.

Further, by engaging the engaging projections 23 of the lower washers 22 with the engaging holes 15 of the supporting member 11, the supporting member 11 is moved outward and pulled out from the hanging bolt 7. Can be prevented. Furthermore, the lower washer 22
By engaging the pair of engaging convex portions 23 with the engaging holes 15 of the support member 11, the notch 14 for bolt insertion of the support member 11 is formed.
Can be prevented from expanding and deforming left and right.

When the support member 11 is attached to the suspension bolt 7, the upper washer 21 and the lower washer 22 are attached.
The bottom plate 12 of the support material 11 can be inserted through the end portions of the support material 11 while gripping the end portions with the fingers and expanding the space between the facing surfaces on the other side with the engaging convex portion 23 interposed therebetween as the support shaft. The insertion work can be easily performed.

By the way, in the above embodiment, the upper washer 21 and the lower washer 22 are used as the position shift prevention tool and the deformation prevention tool, and the lower washer 2 is used.
2 is provided with the engaging protrusion 23, but the present invention is not limited to this, and the upper washer 21 is provided with the engaging protrusion 23 or the upper washer 2
The engaging protrusions 23 may be provided on both the first and lower washers 22.

In the above embodiment, the lower washer 2 is used.
2 is provided with the engaging convex portion 23 and the supporting member 11 is formed with the engaging hole 15, but the present invention is not limited to this, and the supporting member 11 is provided with the engaging convex portion and this engaging portion is provided on the washer side. You may form the engagement hole which engages with a fitting convex part.

Further, the means for engaging the engaging hole 15 and the engaging convex portion 23 is not limited, and for example, a fitting hole is provided in one side and a pin body inserted in the fitting hole is provided in the other side. It may be formed.

A washer is used as the position shift prevention tool and the deformation prevention tool, but the invention is not limited to this.
