Abstract

(57) [Summary] [Purpose] The transportation efficiency of the cable rack body 1 is improved,
A cable rack in which the tip of the support member 3 does not protrude is obtained. [Structure] A cable rack body 1 is configured by pivotally mounting a child spar 7 between vertically extending parent girders 6 and supported by a fixing bracket 2 that holds the inside of the parent girder 6 of the cable rack body 1. It was attached to the member 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to downsizing of a cable rack main body during transportation and means for preventing the tip of the support member from protruding when attached.

[0002]

[Prior Art]

 FIG. 3 shows a conventional cable rack. A cable rack body 1 formed in a ladder shape by fixing a child girder 7 to a parent girder 6 is fixed to a supporting member (bracket) 3 with a fixing bracket 2 and a bolt / nut 5.

[0003]

[Problems to be solved by the device]

 The conventional cable rack is as described above, but when the cable rack main body 1 is assembled in a ladder shape at the factory and transported to the site, it is bulky and therefore the transport efficiency is poor. Further, since the fixing member 2 is attached to the support member 3, there is a problem in that the tip of the support member 3 projects from the outside of the cable rack main body 1 and becomes an obstacle.

The present invention has been made in order to solve the above problems, and it is possible to reduce the size of a cable rack body when it is transported, and to provide a cable rack in which the tip of the supporting member does not project when attached. The purpose is to get.

[0005]

[Means for Solving the Problems]

 In the cable rack according to the present invention, a cable girder is rotatably attached to a main girder to form a cable rack main body, and is attached to a support member with a fixing tool that holds the inside of the parent girder of the cable rack main body. It is a thing.

[0006]

[Action]

 The cable rack body according to the present invention can be folded by rotating the child girder, and when folded, the outer shape becomes smaller and the cable rack is efficiently transported. When this cable rack body is attached to the support member, the angle of the slave girder is set to 90 degrees to form a ladder, and the inside of the parent girder is held down by the fixing tool to attach it to the support member. Is fixed and attached. Since there are no metal fittings on the outside of the main girder, it is not necessary to project the support member outside the cable rack body.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 6 denotes a main girder that extends longitudinally on both sides of the cable rack body 1, and a child girder 7 is attached between the main girders 6 in a ladder shape. The pins 4 for attaching both ends of the child spar 7 to the parent girder 6 are, for example, bolts and nuts, and the bolts are inserted through the holes of the child girder 7 and the holes of the parent girder 6 as shown in FIG. 2B. Then, screw in the nut, and hit the punch without tightening it to prevent it from coming off and attach it. By pivotally mounting the pin 4 in this manner, the sub beam 7 can be rotated with respect to the main beam 6. Therefore, this cable rack can be folded as shown in FIG. In addition, FIG. 1 (B) shows the expanded use state.

A support member (bracket) 3 supports the cable rack body 1, and is attached to the structural member so as to support the weight of the cable via the cable rack body 1. The cable rack body 1 is fixed to the support member 3 by a fixing bracket 2 and bolts and nuts 5. The length of the fixing bracket 2 is the width between the inner side surfaces of the parent girder 6 of the cable rack body 1 in the expanded state, and both ends of the fixing bracket 2 are in contact with the upper inner surface of the lower side of the parent girder 6. By fixing the fixing metal fitting 2 to the support member 3 at 5, the fixing metal fitting 2 is formed so as to hold the main girder 6 on the support member 3.

Next, the operation will be described. Since the pin 4 of this cable rack is rotatably attached to the parent girder 6, the cable girder body 1 is manufactured at the factory and then transported to the installation site as shown in FIG. 1 (C). As shown, when the sub-beam 7 is rotated and folded, the outer volume is reduced, and the transport efficiency can be improved. When this cable rack is attached to the support member 3 at the installation site, as shown in FIG. 1 (B), the cable rack is placed on the support member 3 in an expanded state and fixed between the inner sides of the main beam 6. When the fixing metal fitting 2 is fastened to the support member 3 with the bolts and nuts 5, both ends of the fixing metal fitting 2 come into contact with the upper surface of the inner side of the lower side of the parent girder 6 and hold them down, and the parent girder 6 is supported. Fixed to. This completes the installation, but since it is attached to the support member 3 inside the main beam 6 and there is nothing outside the main beam 6, it is necessary to project the protruding end of the support member 3 from the outer surface of the main beam 6. Therefore, the problems of the conventional protruding portion of the supporting member 3 hindering the effective use of space are solved.

It should be noted that the number of the fixing fittings 2 may not be one at each location, but may be separate left and right bodies. In addition, the cable rack may be foldable by the rotatable pin 4 to reduce the transportation cost only. By fixing the inner side of the main girder 6 with the fixing bracket 2, the supporting member 3 is secured. May not be projected.

[0011]

[Effect of the device]

 As described above, according to the present invention, since the slave girder is rotatably attached to the parent girder and the fixing metal fittings that hold the inner side of the parent girder are attached to the support member, the child girder can be folded and efficiently transported. In addition, the cable rack can be obtained without any protrusion of the supporting member.
