In addition, as shown in FIG. 12, a horizontal and vertical material fixing bracket 100 is installed in the L-shaped angle G, which is a vertical steel tower 13, in a plurality of middle places of the wires L installed on the tower vertical member 13, By coupling the pigtail 400 to the horizontal and vertical material fixing bracket 100 to guide the wire L, the transverse movement of the wire L can be prevented.

In addition, as shown in FIGS. 13 and 14, the pigtail 400 adopts a shape in which both ends of the curved portion 510 cross one or more times with a difference in height between the upper and lower portions, so that the wire L is a pigtail. In the process of inserting into the through hole 410 of the 400, twisting of the wire L can be prevented, and any separation of the wire can be prevented.

In addition, the above-described safety device for preventing a fall of a steel tower may move a fall arrester (not shown) connected to a safety belt of a passenger installed on the wire L without being separated from the wire L. The reason is that in the case of the horizontal and vertical material fixing bracket 100, the vertical material supporter 200, and the vertical material bearing fixing bracket 300, install only one end and the other end of the wire L, or a part where the direction is changed, and the middle of it is a pigtail ( 400,500). Therefore, the rider takes the wire (L) passing through the through holes (410,511) of the pigtail (400,500) to the outside through the outlet (420,513) of the pigtail (400,500), and the fall arrester passes the wire (L). The wire (L) can be brought back into the through holes (410,511) through the outlets (420,513) of the pigtail (400,500).

In this process, the pigtails 400 and 500 form a spiral passage connected from the outlets 420 and 513 to the through holes 410 and 511 or a curved passage intersecting with zigzags, so that the friction path between the pigtails 400 and 500 and the wire L There is no damage to the wire (L) caused by it. When the wire (L) is damaged due to friction with the pigtail (400), the wire (L) may be broken, so it is very important to form the shape of the pigtail (400,500) in a curve to secure the safety of the rider. .

In addition, the spiral passage of the pigtail (400,500) or the curved passage crossing with zigzags prevents any separation of the wire (L) passing vertically through the through holes (410,511), so that the wire (L) becomes the pigtail (400,500). Can be stably supported on.

In the above-described embodiment, the wire L and the life rail L2 may use wires.

The above-described horizontal and vertical material fixing bracket 100, vertical material supporter 200 and vertical material fixing bracket 300 can be attached and detached without additional hole processing on the upper side of the existing pylon 10, and can be used semi-permanently with one installation. In addition, by supporting the wire (L) firmly, it is possible to prevent a fall accident for the rider.

In the above-described embodiment, a horizontal and vertical material fixing bracket 100, a vertical material supporter 200, a vertical material bearing fixing bracket 300, and a pigtail (400,500) are installed on the existing pylon 10 so that the wire (L) is vertically or horizontally Although it has been described as being fixed and supported, it can be applied to a wire fixing device and a support device for various purposes, such as a use for installing a wire vertically installed on a transmission line support such as iron poles.
