Machine-made road spikes, ordinary road spikes, spiral road spikes, Description of frozen road spikes
A road spike is a fastener used to connect rails and sleepers or pads and sleepers. Usually divided into five types: ordinary road spikes, frost-damaged road spikes, threaded spikes, spring spikes, and spiral spikes.
. Ordinary road spikes, also known as hook-head spikes or dog-head spikes, are mainly used for the connection between rails or pads and wooden sleepers. Ordinary road spikes should be made of hot-rolled steel specified in Chinese national standards. The cross-section of the nail bar is square on each side, and the nail length is. The head of the spike is mushroom-shaped, and the shape of the lower part of the spike head is adapted to the shape of the rail bottom. The surface of the nail rod should be smooth and clean, and the flash should not exceed. The displacement of the nail rod relative to the center line of the nail head should not exceed in any direction. There should be no cracks at the connection between the nail head jaw and the nail shaft. The tip of the spike is chisel-shaped, and the chisel is perpendicular to the wood grain when driven in to avoid splitting the wooden sleeper. The cutting edge of the tip is a straight line, and the tip is not allowed to have burrs or folds that may affect use. There should be no bubbles on the surface of the road spikes and no overburning or cracks that would hinder their use
. The material and manufacturing process of the frost-damaged road spikes are exactly the same as those of ordinary road spikes. The spike shaft is longer than ordinary road spikes because it is mainly used for track regulation. It is used when there is frost damage, so it is called frost damage road spike. Depending on the degree of frost damage to the track and the thickness of the frost-damaged pad, the length of the frost-damaged spikes can be divided into:
. Generally made of grade steel. Because the surface of the spike shaft is threaded, it is called a threaded spike. Its pullout resistance is .~times greater than that of ordinary road spikes, but its thrust resistance is % less. Due to the inconvenience of disassembly and assembly and the difficulty of adjusting the track gauge, it is generally used on switches.
.Spring spikes are made of round or square spring steel and come in many types. Because the part that holds the rail has a certain elastic deformation, it can greatly reduce the vibration of the rail, so it is called a spring spike. When the wooden sleeper is deformed under load, it can still maintain sufficient buckling pressure, and its pullout resistance and push resistance are larger than ordinary road spikes, but it is rarely used in China. The picture shows the most commonly used spring spike on the railways of the former Federal Republic of Germany.
.Spiral spike is a part used to connect rails and concrete sleepers. The lower part of the nail rod is threaded and the upper part is a bolt. The nail rod is fixed in the reserved hole of the concrete sleeper with sulfur anchoring (see sulfur anchoring), and the upper bolt is used to fix the withholding parts (such as buckle plates, clips, etc.),
