Gauge apron
Rail coupler is a kind of generic name, it contains spring bar, baffle, gusset plate. The role is to fix the rail, rail pressure plate is also called rail pressure plate, the role is also a fixed track including rail pressure device. Although the name and shape of the type is not the same, but the role and purpose are the same, rail pressure plate and rail pressure device is mainly used for driving or workshop short distance track, rail fastener is generally used on the line, the use of different environment, therefore, if the role of the rail clamping plate should also belong to the rail fastener series.

The rail fastener is described in detail below. The selection of coupler type should match the type of sleeper, rail and rubber pad under rail. The specification and quantity of fasteners should be selected according to the type of track. Laying 60kg/m steel rail track, concrete pillow fastener with type Ⅱ fastener and type Ⅲ fastener, and type Ⅰ will be gradually replaced by type Ⅱ. Laying 50 kg/m rail section, concrete pillow fastener using elastic type Ⅰ fastener; The type 70 rail gusset coupler will be replaced with a spring - strip coupler. Shrapnel type fastenings are no longer used gradually phased out.
The rail pressure plate
For the local line to meet the requirements of the major high volume can be used spring bar type I high fastener. In order to meet the design requirements of seamless lines on long Bridges, small resistance fasteners are used. In order to improve the antirust performance of fasteners, the relevant standards are revised, and the antirust performance requirements of metal parts of fasteners are added. The antirust performance indexes of fasteners are similar to those of high-speed railway fasteners. In order to improve the technical performance and service life of rubber gasket, the revised fastener standard adds the fatigue performance test requirements of rubber gasket.
