Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a relatively low-cost fixing device between a railroad tie and a rail, which can firmly fix a rail on a sleeper, and can be easily removed.

[0002]

[Prior art]

 When constructing dams and waterways as well as railroads and roads, tunnel construction is inevitable in many cases. In such cases, temporary rails will be laid at tunnel construction sites to transport earth and sand and materials. In such a temporary rail, a plurality of metal sleepers made of H-shaped steel are used for arranging the rails, and a number of them are arranged at equal intervals. The two parts are connected and fixed using a rail mounting device at the place where they are required.

In such a conventional mounting device, one disclosed in Japanese Patent Publication No. 59-31601 is provided with a large number of mounting holes in a flange of a sleeper made of an H-shaped steel or an I-shaped steel. The washer and nut of the bolt inserted into the mounting plate engaged on the pedestal part of the hole and the rail are fitted, and the bolt and the nut are tightened to fix the sleeper and the rail via the fixing plate.

[0004] Further, as disclosed in Japanese Utility Model Publication No. 61-11282, an upper mounting plate which is engaged on a pedestal portion of a rail and a lower mounting plate which is engaged on a lower surface of a flange of a sleeper are provided with bolts and washers. The rails are fixed to the sleepers by tightening the nuts with nuts.

[0005] Further, as shown in FIG. 13, in the Japanese Utility Model Publication No. 5-26081, a rail R has a head H, and a rail pedestal RI has an inclined surface RIa at a lower portion. When this is to be mounted on a sleeper flange M orthogonal to the rail R, a rail mounting base A is provided at a place where the two are joined, and the rail mounting base A is provided on the inclined surface RIa of the rail base RI and the sleeper flange M. A holding bolt having a special structure for fixing, ie, a sleeper holding bolt MB and a rail holding bolt RB is provided to fix the rail and the sleeper. P is a sleeper fitting groove.

[0006]

[Problems to be solved by the invention]

 In the above-mentioned Japanese Patent Publication No. 59-31601, it takes time to pass a bolt through a bolt hole and to rotate a bolt or a nut in order to tighten and fix the bolt and the nut. When using a sleeper with multiple mounting holes in the flange, drilling is time-consuming and weakens the strength, resulting in the need for a special sleeper. Furthermore, general H-shaped steel without holes cannot be used. As shown in FIG. 13, Japanese Unexamined Utility Model Publication No. 5-26081 discloses a technique in which a pair of long L-shaped steel members are combined to form an arm-shaped member, and another fixing member is tightened with bolts. Therefore, in the case of a rail mounting device that has an upper mounting plate and a lower mounting plate and sandwiches a rail and a sleeper, there is a problem that the number of parts is large, the cost is high, and it takes time.

[0007] The mounting device described in Japanese Utility Model Publication No. 5-26081, which is said to solve the problem of the prior art, has two special types for fixing the mounting surface of the rail and the flange surface of the sleeper. The use of bolts with a structure makes installation troublesome, and when the rails are removed from the construction site, etc. upon completion of the construction, there is a problem that it takes time to remove many bolts and the like. Bolts that are difficult to remove easily, such as bolts, may rust over a long period of time in places with a lot of moisture, making removal more difficult.

In order to solve these problems of the conventional technology, the present inventor has devised a mounting tool using a wedge as shown in Japanese Utility Model Registration No. 3,054,482, and has obtained great results. That is, the structure is such that a clamp body having a laterally open U-shaped opening and a laterally U-shaped clamp wedge which is also laterally opened are combined, and the rail base is inclined. We have developed a sleeper fixing device consisting of a rail fixing member that is pressed against the surface. Since this fixing device is easily installed and easily detached, it has attracted the attention of the industry for achieving epoch-making results in the construction method. However, since the wedge body has a U-shaped side surface, the processing is somewhat troublesome, and the impact force applied to the wedge during assembly and disassembly is weak, which requires a small amount of work, and further improvement is desired. I was As a result of further study of the wedge-type device, the present inventor was able to produce a fixing device having a simpler structure, a lower cost, and an advantageous construction method.
