摘要
The present invention is to expand or contract the rail of the railway in the longitudinal direction by the temperature or running of the train, the expansion joints of railway rails composed of the points or bridges required in the long rail section, the track before and after the turnout It is about.;Stretch joint according to the present invention is composed of a way that the basic rail (1) and the tongue rail (2) move together, the tongue rail (2) is fixed and the basic rail (1) is moved, the basic rail (1) and the tongue rail (2) is a so-called Samson processing, the basic rail (1) is cut so that the lower part is narrow, and the tongue rail (2) is configured so that the lower part is cut so as to be in close contact with each other by the tip of the tongue (2) The base plate (1) and the tongue rail (2) are formed with a stopper (3 '), and the radius R formed between the contact rails of the basic rail and the tongue rail is made long by a single curved line from 130000 mm to 170000 mm. 3) but fixed to the outside of the basic rail (1) using the rail brace 4 and the bolt (5), as shown in Figure 7. 2) is in close contact with the basic rail (1) and fixed with rail clips (6) and bolts (5) For example, stoppers 3 'are formed in the base plate 3 to support the rail brace and the rail clip, and a part of the tongue rail 2 is formed by drilling a hole 7 in the bottom of the tongue rail 2 (3) and the fixing pin (8) was connected.;The present invention as described above increases the radius R of the contact section where the basic rail and the tongue rail meet each other from 130000 mm to 170000 mm to increase the frictional force and increase the limit of the amount of stretching while increasing the limit of the amount of stretching, while also known as the Samson process. By narrowing the connection section by increasing the length of the gauge, it is possible to reduce the gauge variation and reduce the gauge expansion, thereby improving the riding comfort and stability when the train runs at high speed, and as described above, the reliability of the expansion joint device is improved. Since it is improved, there is no problem in constructing curved tracks, and it is possible to combine and separate parts by constructing expansion joints using rails of the same standard, and the way in which the rail and the basic rail move together, The rails are fixed and appropriate depending on the site conditions such as the way the basic rails move. It can be used in combination with the product, so it is easy to maintain. Also, by installing a well-known adhesive insulation joint on the tongue and connecting it before and after the tap-off, there is no need to add a separate insulation device. Reducing the economic benefits.
