Description

  The present invention is a rail bottom gripping member support structure that can be a support structure that can be attached to other members using the rail bottom, a track pavement structure in which a pavement member is installed in the vicinity of the track and configures a road surface of the road, and the vicinity of the track The present invention relates to a pavement method, a train departure prevention type track structure and a train departure prevention method.

  Conventionally, a railroad crossing where a railroad track and a road intersect with each other has been paved to be used for traffic such as pedestrians and automobiles. As an example, although not shown in the figure, there is a railroad crossing in which a covering material made of wood or stone is laid on the inside and outside of two rails (rails). In the case of this paving material, a guard rail is laid between the inner side of the two rails and the laying material, and the space that should be secured by this guard rail so that the wheel flanges of the railway vehicle can pass without hindrance. A “flange way” was formed.

  Also, in recent years, on level crossings where road width is large and traffic volume is heavy, sleepers at level crossings are removed, and instead of plate-like articulated track plates made of reinforced concrete (RC) or prestressed concrete (PC), etc. Used, a railroad crossing pavement structure called "joint track" is used, in which the left and right rails are housed in the two rail housing recesses provided on the upper surface of the joint track plate, and fastened and supported by mounting bolts, nuts, etc. It has been.

  On level crossings with large road width and high road traffic, reinforced concrete (RC) or prestressed concrete can be used without removing the sleepers at the level crossings as shown in FIGS. 10 (A) and 10 (B). (PC) or the like is used, and the railroad crossing pavement plates 201, 202, and 203 are used as trajectories at the crossings. There is also known a level crossing pavement structure (hereinafter referred to as a “soken type pavement plate type level crossing pavement structure”) that paves a level crossing point by being attached to the upper surface of the sleeper T inside and outside.

  As shown in FIG. 10B, in this research-type paving plate type railroad crossing pavement structure, each railroad crossing pavement plate (for example, inner rail) is formed by a connecting plate 207 and mounting bolts 291 and 292 that support a rail (for example, 300) from below. The rail-side level crossing pavement plate 201 and the outer rail-side level crossing pavement plate 202) are fixed to the track. In FIG. 10A, reference signs F11 and F12 indicate flange ways which are spaces through which the flanges W1 of the wheels W of the railway vehicle pass.

  In the above-described conventional research-type pavement plate type railroad crossing pavement structure, a rubber chute 284 is installed near the head or abdomen of the rail so as to be parallel to the longitudinal direction of the rail. The rubber chute 284 is a beam-like member having a substantially “K” cross section, and is arranged such that its longitudinal direction is parallel to the longitudinal direction of the rail.

  One of the conventional reasons why these rubber chutes 284 are arranged in the vicinity of the rail 300 is to prevent snow from accumulating in the flange way F11 and causing trains to “climb up and derail” in a snowfall area. Met. Also, in recent years, an accident has occurred where an infant gets caught in a rail-containing recess around the rail in the railroad crossing and touches the train, and in order to prevent such personal injury, In order not to leave a recess or a gap other than the flange way, these padding rubber chutes have been used at the crossings. These rubber chutes are made of rubber materials including natural rubber and artificial rubber.

  In addition to the rubber material, a metal material, a synthetic resin material, wood, or the like is also conceivable as a material for the member for filling the gap on the side of the rail 300. However, electrical insulation is required due to contact with the rail, elastic deformation can be used when fitting in a narrow gap, snow and ice are difficult to adhere, impacted snow and ice are hit and elastic deformation accompanying it, etc. A rubber material is used for the reason that it can be easily broken.

  However, since the conventional rubber chute 284 described above has low rigidity and easily deforms, there is a problem in that earth and sand etc. tend to flow downward from between the rubber chute and the connecting track plate and the level crossing pavement plate and accumulate. . In particular, in the Soken-style pavement type railroad crossing pavement structure, when the snow piled up is compressed by the flange of the wheel and becomes icy, the rubber chute 284 falls due to the pressing force from the upper flange. There was also a problem. (See Patent Document 1).

As a countermeasure against the problem of the rubber chute in the above-mentioned general research pavement plate type railroad crossing pavement structure, for example, using the fastening bolt and nut mechanism of the rail fastening device in the general research type pavement plate type crossing pavement structure, Some metal fittings (hereinafter referred to as “fastening device utilization type metal fittings”) are sandwiched and fixed, and this metal fitting is used as a fulcrum in the beam, or a beam-like rubber member disposed along the rail, or It is conceivable to use a method of supporting a steel rod or the like that supports a beam-shaped rubber member with this fastening device utilizing type metal fitting. However, in such a system, if the level crossing pavement structure or the level crossing pavement plate is changed, it is necessary to devise a metal fitting corresponding to the change, and there is a problem that it is complicated.
