Manufacturer wholesales high-quality cement sleepers. The installation methods of cement sleepers are divided into two types: bolts and rings. Cement sleepers are now usually installed with bolts. You can select the type after confirming the rail moment and rail model when you choose.
Sleeper shape The cross-section of the concrete sleeper is trapezoidal, narrow at the top and wide at the bottom. The trapezoidal cross-section can save the amount of concrete, reduce its own weight, and facilitate demoulding. The width of the top surface of the sleeper should be determined by comprehensive consideration of factors such as the bending strength of the sleeper, the rail support area, the width of the pad under the rail, and the size of the intermediate fasteners.
The part of the top surface of the sleeper that supports the rail is called the rail bearing groove, which is made into a slope to adapt to the requirements of the rail bottom slope.
During installation, you only need to pass the profile bolts through the bottom of the sleeper, put on the pressure plate and fix the pressure plate with nuts, so that the rail can be fixed. Explain why you need to use profile bolts, and use ordinary bolts on Tighten the nut when fixing
The rod of the bolt will rotate with the rotation, and this will not happen with the type bolt, making the sleeper more reliable when fixing the rail
