Description

  The present invention relates to a wire member support used to prevent breakage of an electric pole used for supporting a train line or the like during an earthquake, and a seismic reinforcement method using the wire member support.

  Electric poles are mainly used to support power supply lines that supply power to trains and are erected at predetermined intervals along the tracks. Such an electric pole is manufactured as a cylindrical concrete product by pouring concrete into a formwork in which PC steel wires are arranged, rotating the formwork in that state, compacting the concrete, and performing predetermined curing. . The concrete produced by such a method shows a fracture behavior called so-called explosion, which is pulverized at the moment when the limit of strength is exceeded, while it is dense and has high strength with little moisture. That is, it is a characteristic of high strength but small stickiness (brittleness).

  For this reason, if an electric pole vibrates due to an earthquake, the concrete explosion will occur at the moment the critical displacement is reached, and the concrete will be crushed and broken. ing.

Therefore, the inventor disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2013-117088), in the seismic reinforcement method for the electric column (20) built on the foundation (10), is displaced at an appropriate interval from the upper end to the lower side of the electric column.

A seismic retrofitting method for electrified poles was proposed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in this specification, it refers to all the technical matters currently disclosed by patent document 1 (Unexamined-Japanese-Patent No. 2013-1117088), and uses it.

  FIG. 1 is a front view of an electric pole 50 subjected to seismic reinforcement using a wire member support 100 according to an embodiment of the present invention, and FIG. 2 uses the wire member support 100 according to an embodiment of the present invention. It is a perspective view of the electrification pillar 50 by which anti-seismic reinforcement was performed.

  In FIG. 1 and FIG. 2, in order to avoid complication of the drawings, the seismic reinforcement that is symmetrical with respect to the hypothetical center axis of the electrification column 50 with respect to the illustrated seismic reinforcement structure. The structure is not shown.

  When the electric pole 50 is deformed by shaking due to an earthquake, it breaks at the moment when the limit deformation amount is reached. Therefore, in order to prevent the electric pole 50 from being broken due to an earthquake, even if the foundation 30 such as a viaduct vibrates, the electric pole 50 itself may be prevented from shaking as much as possible so as not to reach the limit displacement. Therefore, in this embodiment, the earthquake-proof reinforcement structure for restraining the deformation amount of the foundation part 30 at the time of an earthquake is arrange | positioned.

  In FIG. 1, wire member support tools 100 are attached to a plurality of places at appropriate intervals from the upper end to the lower part of the electric pole 50 built on the foundation 30. The installation interval of the wire member support 100 is set as appropriate, such as narrowing at the lower end and upper end where the applied acceleration and displacement are large and widening the middle.

In the wire member support 100, for example, one end of a pair of semicircular arc bands facing each other is hinge-coupled, and a member (not shown) that can bolt each semicircular arc band free end is electrified column 50.
It is configured by fixing it to the support bracket and attaching it. Or you may make it attach to the electrification pillar 50 by apply | coating an adhesive material or an adhesive material to the bottom face part of the wire member support tool 100 by this.

  One end of a wire member 500 made of steel material, steel wire, synthetic fiber or the like for displacement suppression is attached to a support metal fitting of the wire member support 100 at the upper end of the electric pole 50 at a symmetrical position. They are wound symmetrically and spirally, attached to the support fitting of the wire member support tool 100 and wound to the lower end of the electrification column 50, and the end portion is fixed to the anchor portion 70 provided on the base portion 30. 1 and 2 do not show the seismic reinforcing structure shown in FIG. 1 and the seismic reinforcing structure that is symmetrical with respect to the virtual central axis of the electric pole 50.

  By winding the wire member 500 in a spiral manner in this way, no matter what direction the electric column 50 is subjected to a large acceleration, each portion of the electric column 50 is stretched by the wire member 500 stretched between the wire member supports 100. Therefore, the displacement can be suppressed within a limit displacement that causes breakage.

  Note that the number of wire members 500 is not necessarily two but may be one. Further, the number of wires may be further increased to be spirally wound, and for example, three wire members may be called 120 ° intervals or four wire members may be called 90 ° intervals without necessarily being spirally wound. Thus, by attaching a plurality of wire members to each wire member support tool 100 linearly from the upper end to the lower end of the electric pole 50 at a predetermined angular interval and fixing them to the base portion 30, the electric pole 50 from any direction It is possible to restrain the displacement even if acceleration acts on the. By constraining the displacement of the electric pole 50, the influence on the base of the electric pole 50 is also reduced, which is effective in preventing damage to the base of the electric pole 50.

  In the seismic reinforcement method as described above, it is important in terms of construction to introduce an appropriate tension to the wire member 500, which is a displacement suppression reinforcing material passed between the two wire member supports 100. .

The same effects as those of the previous embodiment can also be obtained by the above-described seismic reinforcement method using the wire member support 100 having the jack structure 600 and the wire member support 100 having the jack structure 600. Can do.

  As described above, the wire member support according to the present invention has a loop portion around which the wire member is hung and provided with an extending rod extending in the longitudinal direction. According to the member support tool, it is possible to easily introduce an appropriate tension to the wire member so that the wire member is not placed in a loose state during the construction.

  Moreover, according to the seismic reinforcement method using the wire member support according to the present invention, it is possible to perform the seismic reinforcement work for the electrified column 50 simply and in a short time.
