Abstract

PROBLEM TO BE SOLVED: To provide a railroad crossing board retaining no rainwater on surface and allowing an easy installation work. SOLUTION: Rubber tips are solidified by use of an adhesive for forming both of an inner track board 1 and an outer track board 2 having porous quality and water permeability, thereby causing rainwater to permeate down from surface. In addition, engagement projections 3 for engagement with a rail neck are formed at both sides of the inner track board 1 and at one side of the outer track board 2, so that the engagement projections 3 are coupled to the neck of the rail R and positioned along a track direction. Also, a hollow reinforcement material 6 of resin is embedded in the inner track board 1 and the outer track board 2 for increasing strength without losing lightweight quality.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad crossing plate which is laid inside and outside a gauge to secure passage of a road crossing a track.

[0002]

2. Description of the Related Art In general, wooden crossing boards and reinforced concrete (RC) crossing boards are used. At the time of installation, these railroad crossings are fixed to individual sleepers with bolts, and the movements in the track direction and the track direction are restricted by the bolts.

[0003]

However, with the level crossing plate as described above, there is a problem that rainwater accumulates on the surface and the water freezes in the winter, which causes a risk of slippage. There is also a problem that it takes a lot of time to fix it.

Furthermore, the wooden ones have poor durability, and RC
Since the product made from the product has a large weight, there is also a problem that a heavy machine or the like is required at the time of installation.

Therefore, an object of the present invention is to provide a railroad crossing plate which is easy to install without rainwater staying on the surface thereof.

[0006]

In order to solve the above-mentioned problems, the present invention forms a porous and water-permeable plate-like body by hardening a rubber chip with an adhesive, and the rail-like body of the rail is formed on the plate-like body. Provided is a railroad crossing plate provided with an engagement protrusion that engages with a neck portion.

In this railroad crossing plate, rainwater permeates downward from the surface, and ice frozen inside is also crushed by the elasticity of rubber, so that water retention does not freeze on the surface and slip accidents are prevented. It

Further, since it is light in weight, it can be installed by human power, and at the time of the installation work, the engaging convex portion engages with the neck portion of the rail and is positioned in the track direction, which is excellent in workability. Will be things.

Further, when the reinforcing material is embedded, the reinforcing material acts as a load bearing beam and the strength is improved, so that it can withstand the passage of a large vehicle and the durability is also improved.

When a resin hollow plate or a steel pipe is used as the reinforcing material, the strength can be improved without impairing the lightness.

Besides, since it can be molded into an arbitrary shape,
Since various types of sleepers and fastening devices can be supported and the rubber chips can be recycled, it is possible to effectively use resources.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 4, there are two types of railroad crossing plates, an inner rail plate 1 and an outer rail plate 2, and the inner rail plate 1 is sized so as to straddle two sleepers T. The outer rail plate 2 is sized so as to straddle three sleepers T. The inner track plate 1 and the outer track plate 2 are made of old tires having a grain size of 3 to 3.
A rubber chip crushed to about 1 mm is solidified with an adhesive to form a porous and water-permeable plate. As the adhesive agent, for example, Takenate F139 manufactured by Takeda Pharmaceutical Co., Ltd. may be used in an amount of 10 to 30%.

On both sides of the inner rail plate 1 and on one side of the outer rail plate 2, engaging projections 3 for engaging with the neck portion of the rail R are provided, and on both upper sides of the inner rail plate 1, wheels are provided. Notch grooves 4 that allow passage of the flanges of the rails are formed, and recesses 5 that avoid interference of the fastening device C with the sleepers T of the rails R are formed at lower portions on both sides of the inner rail plate 1 and the outer rail plate 2. .

Further, four reinforcing members 6 are embedded in the inner track plate 1 in the track direction and three reinforcing members 6 in the track direction, and the outer track plate 2 is provided.
Two reinforcing materials 6 are embedded in the track and six in the track direction.

In this example, a hollow plate made of hard vinyl chloride and having a plurality of ribs is used as the reinforcing material 6, but instead of this, a steel pipe or the like may be embedded.

When constructing a railroad crossing using the inner rail plate 1 and the outer rail plate 2 as described above, the outer rail plate 2 is placed on the outer portion of the railroad tie T, and the engaging projections 3 thereof are provided. The inner rail plate 1 is engaged with the outer neck portion of the rail R, the inner rail plate 1 is pushed into the gauge, and the engaging convex portion 3 is elastically deformed and engaged with the inner neck portion of the rail R.

Then, as shown in FIGS. 1 and 5, the fixing metal fittings 7 are hooked on the inner side surfaces of the sleepers T at both ends of the railroad crossing, and the inner rail plate 1 and the outer rail plate 2 laid by a predetermined number are bolted through the pads 8 through the pads 8. Tighten with. It should be noted that, as shown in FIG. 6, it is preferable to provide slope-like return plates 10 at both ends of the railroad crossing for assisting the return of the derailed vehicle to the railroad crossing plate.

At the time of this installation work, since the inner rail plate 1 and the outer rail plate 2 are lightweight, without using a heavy machine or the like,
Since it can be installed by human power, and the engaging projection 3 is engaged with the neck of the rail R and positioned in the track direction,
All you have to do is restrict the movement in the track direction with the fixing metal fittings 7.
Can be easily installed.

When the railroad crossing is constructed as described above, the inner rail plate 1
Also, in the outer rail plate 2, rainwater permeates downward from the surface, and ice frozen inside is also crushed by the elasticity of rubber, so that water retention does not freeze on the surface and a slip accident is prevented. .

Further, since the embedded reinforcing member 6 acts as a load bearing beam to improve the strength, it can withstand the passage of a large vehicle and is excellent in durability. Since the reinforcing member 6 is hollow, the lightness of the inner rail plate 1 and the outer rail plate 2 is not impaired.

In addition, since the inner rail plate 1 and the outer rail plate 2 can be molded into arbitrary shapes, they can be used for various types of sleepers and fastening devices, and rubber chips can be recycled for use. Can be effectively used.

[0022]

As described above, since the railroad crossing plate according to the present invention is formed into a porous and water-permeable plate shape by solidifying rubber chips with an adhesive, rainwater permeates downward from the surface, The ice frozen inside is also crushed by the elasticity of rubber, so that water retention does not freeze on the surface, and the occurrence of slip accidents is prevented.

Further, since it is light in weight, it can be installed manually, and since the engaging convex portion which engages with the neck portion of the rail is provided, the engaging convex portion engages with the neck portion of the rail during the installation work. Together, they are positioned in the track direction, and have excellent workability.

Further, in the case where the reinforcing material is embedded, the reinforcing material acts as a load bearing beam and the strength is improved, so that it can withstand the passage of a large vehicle and the durability is also improved. If a resin hollow plate or a steel pipe is used as the reinforcing material, the strength is improved without impairing the lightness.

In addition, since it can be molded into any shape,
Since various types of sleepers and fastening devices can be supported and the rubber chips can be recycled, it is possible to effectively use resources.
