  First, the railroad rail branching device 11 is constructed by laying a pair of basic rails 13 and 13 and a pair of tongrails (movable rails) 14 and 14 on sleepers 12 arranged at predetermined intervals. A connecting rod 15, a switch adjuster 16, and a lock cane 17 are provided at the front ends of the rails 14, 14. The switch adjuster 16 is moved by a switch 18 disposed on one side of the branching device 11, and the tongue is moved. The rails 14 and 14 are converted, and are locked in the conversion position by a lock lock 17.

  A basic rail electric snow melter retainer (hereinafter referred to as a retainer) 21 is attached to the basic rail 13 between the sleepers provided with the connecting rod 15 and the switch adjuster 16, and the electric snow melter 22 is connected to the basic rail 13. It is pressed against the outer surface of the rail of the abdomen 13a. The presser fitting 21 rises from a bottom plate 23 arranged along the bottom lower surface 13b of the basic rail 13 and the rail outer end portion of the bottom plate 23, passes over the bottom of the basic rail 13, and faces the outer surface of the abdomen 13a. Bent plate 24, back plate 25 rising from the tip of bent plate 24 in a direction parallel to the outer surface of abdomen 13a, and spring members 26 and 26 at both longitudinal ends of back plate 25, respectively. And a reinforcing plate 28 having a U-shaped cross section provided as a reinforcing portion in the longitudinal direction of the back plate 25 on the surface of the back plate 25 on the abdomen 13a side. ing.

  The back plate 25 is a horizontally long rectangular shape provided in a state of extending to one side along the abdomen 13 a of the basic rail 13 with respect to the bottom plate 23 and the bent plate 24. The bent plate 24 and the bottom plate 23 are formed in the lower part near one end part outward and downward. Further, reinforcing pieces 25a and 25a as reinforcing portions bent in the anti-rail direction are provided on the upper edge and the lower edge of the back board 25, respectively, and the bending rigidity of the back board 25 is improved together with the reinforcing board 28. Yes.

  The bottom plate 23 is formed in a shape that is bent in an inverted mountain shape in which the bottom portion bottom surface width direction central portion 23a of the basic rail 13 protrudes downward, and the strength in the length direction is improved. At the tip of the bottom plate 23, there is provided an inner engagement piece 23b that is bent upward at a height that does not interfere with the Tongler 14 and engages with the bottom inner edge 13c of the basic rail 13. In addition, an outer engagement piece 25b that engages with the bottom outer edge 13d of the basic rail 13 protrudes downward at a position adjacent to the outside of the bent plate 24 in the lower part of the back plate 25 in the anti-extending direction. When the presser fitting 21 is attached to the basic rail 13, the bottom of the basic rail 13 is sandwiched between the inner engagement piece 23b and the outer engagement piece 25b.

  The spring member 26 is obtained by bending a metal plate having a predetermined width and thickness into a U shape so as to obtain a predetermined elastic force. The sandwiching pieces 27a and 27a for sandwiching 22 are formed so as to face each other, and a plurality of engagement protrusions 27b for preventing displacement of the electric snowmelter 22 are provided on the mounting surface of the electric snowmelter 22 of the holding plate 27. It has been. The spring member 26 and the pressing plate 27 can be formed in the same manner as that described in Patent Document 2.

  The presser fitting 21 thus formed is inserted with the bottom plate 23 along the bottom lower surface 13b from the outer side of the track of the basic rail 13 with the electric snow melter 22 held between the holding pieces 27a, 27a of the presser plate 27. While the spring member 26 is elastically deformed, the front inner engagement piece 23b is engaged with the bottom inner edge 13c of the basic rail 13, and the outer engagement piece 25b of the back plate 25 is engaged with the bottom outer edge 13d of the basic rail 13. Engage with. At this time, by using the elastic deformation due to the bent shape of the bottom plate 23, the bottom portion of the basic rail 13 is clamped by the elastic force of the bottom plate 23 by the inner engagement piece 23b and the outer engagement piece 25b. Positioning, in particular, parallelism between the back plate 25 and the abdomen 13a can be ensured, and the press fitting 21 can be prevented from being loosened or moved by train vibration.

  Further, by attaching the bottom plate 23 to the bottom portion of the basic rail 13 in a predetermined state, the spring member 26 is elastically deformed, and the electric snowmelter 22 is attached to the abdominal portion 13a of the basic rail 13 via the holding plate 27 by the elastic restoring force. It is strongly pressed against the outer surface of the track, and the entire length direction of the electric snow melter 22 can be securely adhered to the abdomen 13a, and the heating efficiency of the basic rail 13 by the electric snow melter 22 can be improved.

  Further, a U-shaped reinforcing plate 28 is fixed in the longitudinal direction of the back plate 25 by welding or the like, and reinforcing pieces 25a are formed as reinforcing portions in the longitudinal direction of the upper and lower edges of the back plate 25, respectively. Thus, the bending rigidity of the back plate 25 can be increased while suppressing the increase in weight as much as possible without greatly increasing the thickness of the back plate 25. Thereby, the back plate 25 is supported by the bottom plate 23 and the bent plate 24 in a cantilever state, and the gripping of the basic rail 13 by the spring member 26 on the bottom plate 23, the bent plate 24 and the bottom plate 23 side is the length direction of the electric snow melter 22. Even if the position is shifted to one side in the length direction instead of the center, it is possible to increase the resilience of the spring member 26 and generate a sufficient pressing force on both pressing plates 27, and away from the bottom plate 23. The pressing force of the pressing plate 27 provided on the extending end side of the back plate 25 is not reduced by the warp deformation of the back plate 25. Further, by providing the outer engagement piece 25b that engages with the bottom outer edge 13d of the basic rail 13, the extending end side of the back plate 25 is rotated away from the basic rail 13 with the bent plate 24 being the center of rotation. The moving movement can be regulated.

  Therefore, the dimension of the bottom plate 23 in the rail direction can be made smaller than before, and when the presser fitting 21 is attached to the tip of the branching device in which the two connecting rods 15 and the switch adjuster 16 are provided, the presser fixture 21 And the connecting rod 15 and the switch adjuster 16 can be sufficiently widened, so that there is no possibility that the holding bracket 21 and the connecting rod 15 or the switch adjuster 16 come into contact with each other to cause a track short circuit. The entire area between the rail fastening devices including the portion located above the connecting rod 15 and the switch adjuster 16 can be heated well. As a result, the distance between the basic rail 13 and the Tongle rail 14 is greatly increased, and snow melting and de-icing can be effectively performed in a portion where the amount of snow accumulation due to snowfall or snowfall is increased, and the occurrence of the malfunction of the Tongrel 14 is avoided. can do.

  The material of the presser bracket 21 can be selected from the same material as the conventional presser bracket, and the shape of each part is the shape of the basic rail, the space between sleepers, the state of the connecting rod and the switch adjuster, and other conditions. It can be set appropriately depending on the situation. The bottom plate 23, the bent plate 24, and the back plate 25 of the presser fitting 21 can be integrally formed by bending a metal plate formed in a predetermined shape, and the spring member 26 and the presser plate 27 are formed of rivets. It can join by appropriate joining means, such as joining. Further, the arrangement and shape of the reinforcing portion are also arbitrary. For example, a member having a V-shaped cross section may be fixed to the back plate 25.
