Abstract:
PROBLEM TO BE SOLVED: To provide a support structure for a power cable intermediate connection box that absorbs extension of power cable and that is able to decrease a difference between left and light axial forces.SOLUTION: A pair of support members 9 are joined to upright metal fittings 5 at a predetermined interval. That is, the support members 9 are fixed to a manhole wall 7. The vicinities of the upper end parts of a pair of suspension plates 11 are connected to each support member 9. The support member 9 and each suspension plate 11 are connected via a shield bearing 13. A connection-box fixing frame 15 is connected to the vicinities of the lower end parts of the suspension plates 11 via the shield bearings 13 and shafts 17. That is, the connection-box fixing frame 15 is suspended from the support member 9 by the suspension plates 11, and the suspension plates 11 are rotatably mounted on the support member 9 and the connection-box fixing frame 15, thereby connecting the support member 9 and the connection-box fixing frame 15.SELECTED DRAWING: Figure 3
