The former has the disadvantage of being expensive and the latter having a large volume. The present invention utilizes old rails that would otherwise be wasted and replaces them, and is particularly suitable for use in locations such as station premises where a small footprint is required.

る。 Examples will be described with reference to the drawings. A rail bundle is formed by aligning the ends of three rails 1 of equal length cut to an appropriate length and inserting the heads of each into the narrow part of the other midsection. A bolt hole 1a is bored in each midsection. The clamping plate 2 is a rectangular plate that is fitted into the narrow midsection on both sides of the rail bundle, and is fixed to the rail bundle by bolts 3 passing through holes 1a, and one end thereof is attached to a protrusion 2a from the rail bundle. It is becoming. The protrusion 2a is locked to the wire 5 via the bolt 4. Bind the other end of the rail bundle using an arbitrary method. The figure shows binding using a through bolt 6. The number of old rails is limited to three, with three of appropriate length.
This is because the book is sufficient to obtain the required weight, and it is not difficult to tighten the bolts through the clamping plate.

Suppose you use an old rail with a nominal weight of 50 kg when you need a 330 kg weight. Old rails are replaced when wear reaches a limit of 5%, so the weight per meter is around 48 kg. Therefore, the required length L of the rail bundle is 2300 mm. This weight adjustment can be easily achieved by adjusting the cut length of the rail. In addition, when the tension adjustment span is 500 m, the ground height l of the bottom end of the rail bundle is 2000 mm at the minimum temperature (-20℃) (Fig. 2) and at the maximum temperature (40℃).
It becomes 480mm (Figure 3). In other words, the vertical adjustment length is
1500mm is sufficient. Next, the cross section of the rail bundle is approximately 250 mm at its maximum diameter, while the diameter of the utility pole P is 350 mm.
Since it is 400mm, it can be used in narrow spaces that are incomparable to conventional weights. Furthermore, since the rail bundle has no protrusions outside its cross-sectional profile over its entire length, it is sufficient to provide a simple surrounding frame K that directly surrounds the rails to prevent the weight from steadying. One item is enough. By appropriately selecting the mounting position, even if the weight should fall due to a break in the wire, it is possible to keep the vicinity of the upper end within the enclosure frame K, and safety is ensured.
