How to install the rail fasteners better

rail fasteners

Generally, there are two types of rail beams for installing rail fasteners, one is concrete material and the other is steel structure material. For concrete beams, pre-embedded holes must be reserved in advance when building beams. These holes are used for bolts when installing rail fasteners. Of course, bolts can also be directly buried in beams.

Commonly used installation methods include hook screw fixation, pressure plate fixation, welding, and bolt combination fixation. When punching, the depth of the hole must be deep enough. This is to facilitate the later adjustment in the horizontal direction. If you need to adjust in the vertical direction, remember to put a cushion under the rail.

The material of the rail fasteners is different and the rigidity is also different. It can be set to single-hole or double-hole according to the force situation on site. There are also many connection methods to choose from. It should be noted that only when the steel backing plate and the rail are welded At the same time, the rail fixing parts can be installed in the same welding method, so there are certain limitations. However, the firmness of the welding is the best. As long as the anti-rust measures are in place at ordinary times, the welding can be used for a long time without loosening or falling off.

There are also certain requirements for the rail beams when installing the rail fasteners. The distance between the horizontal and vertical reserved bolt holes needs to be more than 5 mm, which is convenient for the later fasteners; the diameter of the screw holes should also be larger than the actual diameter of the bolts. Larger, generally 3 mm is enough, otherwise, it may be blocked and other reasons that cannot be installed.
