鉄道フィッシュプレート – 高耐久鉄道接続用の高品質

When two steel rails come together, a railway fishplate, also called a rail joint bar or splice bar—locks them firmly in place. This seemingly simple piece of metal plays a crucial role: it ensures the rails stay perfectly aligned, bears the weight and stress of passing trains, and upholds the safety and reliability of the entire track system.

This guide will help you understand key fishplate specifications—including dimensions, 材料, hole spacing, and types—so you can choose the right product for your needs.

1. 鉄道魚板とは?

A railway fishplate is a sturdy metal bar that bolts onto the ends of two rails, holding them together with precision. It reinforces the track, keeps the rails perfectly aligned, and channels the weight and forces from one rail to the next. Since each rail has its own unique profile, choosing this important railway parts that matches the rail section exactly is crucial—this is why careful attention to specifications makes all the difference.

Because every rail type has a unique profile, it’s essential to match the fishplate to the exact rail section. That’s why paying attention to specifications matters.

2. Why Fishplate Specifications Matter

Selecting the correct fishplate ensures:

A stable and continuous rail connection

Proper track gauge and alignment

Smooth load transfer, even under heavy traffic

Reduced vibration and lower risk of rail breakage

Full compatibility with rail bolts and tie plates

Using incorrect specifications can lead to rail movement, loose bolts, or even derailment risks.

3. Common Fishplate Specifications by Rail Type

Fishplate sizes are designed to match specific rail models. Here’s a practical breakdown covering the most widely used types across Asia, アフリカ, the Middle East, 南アメリカ, and industrial railways.

Light Rail Fishplate Specifications

Heavy Rail Fishplate Specifications

Crane Rail Fishplate Specifications (QU Series)

We also supply fishplates conforming to international standards such asBS47 (例えば, BS80A, BS75R) そしてUIC series (例えば, UIC54, UIC60).

4. Key Dimensional Parameters

A complete fishplate specification includes:

長さ – depends on rail weight and expected load.

Thickness – influences strength and stiffness.

Bolt Hole Diameter – typically 18–25 mm.

Bolt Hole Spacing – must match the rail’s drilling pattern.

Number of Bolt Holes – commonly4-hole または6-hole designs.

Surface Contour – ensures a perfect fit with the rail head and foot.

We also support customized specifications for industrial and mining railways.

5. Types of Railway Fishplates

Standard Fishplate
Used in conventional railways and light industrial tracks.

Heavy-Duty Fishplate
Thicker and stronger, ideal for high-speed lines and heavy axle loads.

Insulated Fishplate
Made of composite or fiberglass; used in electrified railways and track circuit sections.

Forged Fishplate
Offers higher strength, suitable for demanding conditions.

Cast Steel Fishplate
A cost-effective solution for light to medium-duty applications.

6. 材料

We offer fishplates in several materials to suit different performance needs:

Q235 Rolled Steel – A reliable choice for general use.

Forged Steel – Provides enhanced strength and durability.

ダクタイル鋳鉄 – Known for its good mechanical properties and impact resistance.

All materials can be produced to meet international standards such as AREMA, BS, UIC, TB/T, or JIS, depending on your region.

7. How to Select the Right Fishplate

Here’s a simple checklist to help you choose:

Identify the exact rail model (例えば, 50 kg, UIC60, QU100).

Confirm bolt size and hole spacing.

Select the material grade based on load and environmental conditions (例えば, 腐食, 温度, インパクト).

Consider special types like insulated fishplates for track circuits.

Provide your supplier with a rail drawing or profile standard for accurate matching.
