FIG. 4 is an explanatory view showing a facility state using a conventional cable rack washer, and FIG. 5 is a perspective view of another embodiment of the cable rack washer of the present invention. Reference numeral 1 denotes a side plate as a first member elongated in the width direction, which is formed to be longer than a conventional washer, and a flat plate 4 as a fourth member connected to the side plate 1 and a vertical member is provided at a predetermined position. A hole 5 extending in length and penetrating through a bolt 9 for hanging is formed in the center of the flat plate 4.
Reference numeral 2 denotes a bent portion which is formed by bending a central portion of the flat plate 4 and arranged in parallel with the side plate 1, and a bent portion 2 which is a second member.
The flat plate 4 portion is formed wide by being connected near both side ends of the
Holders 3, 3 for holding a main girder 6 formed by bending the end thereof in parallel with the bent portion 2 are formed. The holder 3, which is the third member, is also parallel to the side plate 1. Is substantially equal to the bent portion 2 and is slightly shorter than the side plate 1. Reference numeral 7 denotes a sub-girder which is bridged between the main girders 6 and 6 forming a cable rack and is fixed to the main girder 6 by rivets 10 at a bent fixing portion 8. Is placed and wired.

The facility work of the cable rack washer according to the present invention will be described.
The main girder 6 is fitted between the main girder 6 and the holding part 3, and the main girder 6 is also fitted from the other lower side. Then, the bolts 9 are passed through the holes 5 and 5, and a pair of cable rack washers are tightened with the nuts 9 'to fix the cable rack washers to the parent girder 6 so that the cable rack can be hung on a ceiling or the like. When attaching the cable rack washer to the fixing part 8 of the child girder 7 in the parent girder 6 in relation to the hanging position of the ceiling, the fixing part 8 of the child girder 7 is arranged between the holding parts 3 and 3 (FIG. 2). (See FIG. 3). The holding portion 3 and the bent portion 2 are pressed down from above the main girder 6 to fit the fixing portions 8 of the main girder 6 and the child girder 7 (see FIG. 3). At this time, the head of the rivet 10 of the fixing portion 8 of the child beam 7 is
It is located in between and does not hinder the mounting of the washer. The side plates 1 and 1 of the pair of cable rack washers are brought into contact with each other to butt together,
