Usually, there are two types of raw materials for track beam installed by track plate manufacturers, one is mixed soil raw material and the other is steel structure raw material. On the concrete beam, the embedded holes must be left in advance when building the beam. These holes are used when installing the fixed parts, and of course, the bolts can be directly buried in the beam. On the device method commonly used rail pressure plate, pressure plate fixation method, welding and bolt joint fixation. The depth of the hole must be deep enough when drilling, which is to facilitate the later adjustment in the horizontal direction. If the demand is adjusted in the vertical direction, remember to pad the rail under the rail. Rail clips raw materials of different rigidity is different also, according to the stress of the scene is set to single span and double holes, cohesion of the way there are many to choose from, demand note is only when the steel plate and trajectory is welded, the fixing parts are in the same way welding device, so there will be limitations. However, the solid performance of welding is better. As long as the rust prevention measures are in place at ordinary times, the welding can be used for a long time, and there will be no loosening or falling off. There are certain requirements for the track beam when installing the track plate. The deviation between the transverse and longitudinal reserved bolt holes is more than 5 mm, which facilitates the later fixing parts according to the chapter. The diameter of the screw hole should also be larger than the actual diameter of the bolt, generally 3 mm can be, otherwise it may be blocked and other reasons for the device.
