  According to a second means of the present invention, in the first means, the different color means is formed by continuously embedding three different color pieces in an insertion hole bored inwardly within the thickness of the guide side edge. It is characterized by this.

  According to a third means of the present invention, in the first means, the different color means has three parallel grooves recessed from the vicinity of the guide side edge on the guardrail plate, and the three parallel grooves are melted in different colors. It is characterized by being poured into a plastic and solidified.

  The fourth means of the present invention is characterized in that, in the first, second or third means, the colors of the different color means are blue, green, yellow and red in that order from the induction side edge to the inside. It is.

  According to the present invention of claim 1, even an inexperienced person can easily, quickly and safely visually recognize the wear amount of the guardrail by the color appearing on the guide side edge without entering the railway line. It is only necessary to replace the guard rail when it is exposed, and the inspection work efficiency is improved.

  According to the second aspect of the present invention, in addition to the effect of the first aspect, the position is hardly affected by ultraviolet rays and other external conditions, and is not easily deteriorated.

  According to the third aspect of the present invention, in addition to the effect of the first aspect, the operator can visually recognize the position most easily.

  According to the fourth aspect of the present invention, in addition to the effect of the first, second, or third aspect, since it is the same color as the traffic signal, there is no need to store it again, and it is possible to know when the guardrail is replaced in a reflective manner It is practical.

  As shown in FIG. 2, the inner basic rail S <b> 1 and the outer basic rail S <b> 2 are fixed by a well-known fixing means on a floor plate 9 fixed to the sleeper 8 at an interval. For example, the upper end of the rail brace 11 abuts against the abdomen or neck of the basic rails S1 and S2, and the rail brace 11 is erected and fixed to the floor plate 9 by bolts and nuts.

  In the vicinity of each of the basic rails S1 and S2, an inner tongrel T1 and an outer curved tongler T2 are installed on the floor plate 9 so as to be switchable.

  The guardrail G has a flat belt shape as shown in FIG. 3, the guide side edge 1 gently descends and slopes toward both ends, the extreme ends steeply steeply in a trumpet shape, and has an L-shaped cross section as shown in FIGS. It is a shape. Further, among the plurality of floor boards 9, 9, 9... Installed at intervals, as shown in FIG. 2, the upright pillars 12 are projected from the inner floor boards 9, and the upright pillars 12 and the guard rails G are respectively provided. Bolts 15 are passed through the drilled insertion holes 13 and 14 and nuts 17 are tightened via washers 16 so that the guide side edge 1 of the guard rail G is spaced from the basic rail S1 and is higher than the basic rail S1. Install so that it comes to. In addition, as shown in FIG. 1, the guard rail G is installed in the position where the center in the longitudinal direction substantially coincides with the tip T1 'of the Tongrel T1.

In the first embodiment of the present invention, the insertion holes 4, 4, 4,... Are spaced at five locations as shown by the broken lines in FIG. 3, and the guide side edge 1 is shown as shown in FIG. Drilled inwardly in the wall thickness 3. Moreover, the height position of each insertion hole 4 is the center of the thickness 3. Here, between the insertion holes 4 on both sides and the adjacent insertion holes 4 shown in FIG. 3, the impact at the time of wheel contact is greater than that of the other insertion holes 4, 4 and 4, and the amount of wear is large. The interval is smaller than the interval l2, so that it is possible to detect the replacement time of the guardrail G at an early stage.

  The depth of each insertion hole 4 shown in FIGS. 4 and 5 is 15 mm, and a plurality of different color pieces, more specifically, three different color pieces 5 a, 5 b, 5 c are continuously connected to the insertion hole 4 as the different color means 2. Insert and bond and embed (see FIG. 6). Each of the different colored pieces 5a, 5b, and 5c has a diameter of 5 to 10 mm and a length of 5 mm, the different colored piece 5c in the back is red 7c (shown by dots in the drawing), and the middle colored piece 5b is yellow 7b ( The different colored piece 5a in front is formed of a blue or green 7a (shown by ◯ mark) plastic, for example, an acrylic resin.

  In the second embodiment of the present invention, as indicated by a two-dot chain line in FIG. 3 and a solid line in FIGS. 7 to 9, on the rail plate G ′ surface of the guard rail G and at a constant distance from the guide side edge 1. l3, specifically, each l3 has an interval of 5 mm, and a plurality of, specifically, three parallel grooves 6a, 6b, 6c are provided in parallel with the guide side edge 1. These parallel grooves 6a, 6b, and 6c are each 1 mm wide and 2 mm deep, red 7c (shown as dots in the figure) in the parallel groove 6c in the back, and yellow 7b (in the figure in the figure) as the center parallel groove 6b. A blue or green 7a (shown by a circle in the figure) molten plastic, specifically a molten acrylic resin, is poured into the parallel grooves 6a in the front, and solidified by pouring.

  Next, the operation of the present invention will be described. As shown in FIG. 2, the wheel W1 rotates back and forth on the basic rail S1 and the wheel W2 rotates back and forth on the basic rail S2 and the tongrel T2. At this time, as shown in FIG. 1, the load from the wheel W2 is greatly applied outward by the centrifugal force to the outer rail side basic rail S2 and the Tongler T2, and if there is no guard rail G, the basic rail S2 and the Tongler T2 are large. Wear force is applied, and in some cases, the wheel W2 may ride on the basic rail S2 and the tongrel T2.

  For this reason, the guide side edge 1 of the guardrail G is in contact with the back surface of the wheel W1 to prevent the wear and climbing. However, a large wear force is applied to the guide side edge 1 and gradually wears due to aging. Here, in the first embodiment of the present invention, while the blue or green colored pieces 5a of FIG. 6 are visible, the wear amount is safe within 5 mm, and the colored pieces 5b of yellow 7b are visible and exceed 5 mm. The guardrail G is exchanged when the precaution is prepared and the red colored piece 5c is visually recognized.

  In the second embodiment of the present invention, when the guide side edge 1 is worn down to the blue or green color 7a of the parallel groove 6a, it is found that the wear is almost 5 mm, and when it reaches the yellow color 7b of the parallel groove 6b, it is worn down to about 10 mm. Get ready for replacement. In the unlikely event that only the red color 7c is visible, the wear amount has exceeded 10 mm, so the guardrail G is immediately replaced.

  Regardless of the first or second embodiment, even a person who has little inspection experience can easily and quickly visually recognize the wear amount of the guardrail from the outside without worrying about the work interval. In particular, in the second embodiment, since the display according to color is provided on the surface of the guardrail, it is very easy to visually recognize. In the first embodiment, since the color display is embedded in the thick part of the guardrail, it does not deteriorate due to ultraviolet rays or other external factors.
