Abstract

A rail fastening comprises a resilient U-shaped clip the base of which is supported against the sleeper with the free outer ends of the clip arms engaging the rail foot. Holding down means acting against an intermediate portion of the arms stresses the clip to clamp the rail foot. The intermediate arm portions are circularly curved in a vertical plane, and the holding down means engaging the curved portions has a complementary shape. This enables greater deflection of the clip for a given clamping pressure. The outer end portions are flattened where they engage the rail foot. [US3784098A]

PL PLA device for fastening a rail to a sleeper and the subject of the invention is a device for fastening a rail to a sleeper. There is a device for fastening a rail to a sleeper by means of a U-shaped elastic clamp consisting of a base and two arms, resting on the base on the base, the ends of the arms with the foot of the rail and, with the center of the arms, a reaction element connected to the underlay. A disadvantage of this type of solution is the necessity to check the magnitude of the rail fastening force as well as the difficulty in adjusting this force. The aim of the invention is to avoid the above-mentioned disadvantages. This object is achieved in accordance with the invention in that each of the two arms of the tab has a circular arc bend at its medial portion in contact with a similarly shaped reaction member, the height of each arm being reduced from the curvature to its end, and the width of each arm extends from the bend to its end. The main advantage of such a paw is that it has the possibility of a long bend while rotating each arm around the center of the curvature of the bend, 'and that an increasing bend can be obtained. The clamp cooperates in the rail fastening system with a reaction element formed by a mounting head mounted on the support by means of a mandrel and is bent by it in order to exert a force on the ends of its arms. that fastens the rail, while the base of the tab rests on the support, and the fastening is done by screwing the nut onto the spindle. 1 is a side view of the spring tab, FIG. 2 - tab in top view, fig. 3 - device for fastening the rail to the base with a tab, in vertical section, fig. 3a - first stage of assembly of the device from fig. 3, fig. 3b - second step assembly of the device of fig. 3, fig. 3c - third phase of assembly of the device of fig. 3, fig. 4 - device of fig. 3, in top view, fig. 5 - head for fixing the tab, in perspective view, fig. 6 - diagram of the dependence of the clamping force of the tab as a function of its deformation. Tab 30 {Fig. 1 and 2), made of steel, is generally U-shaped and has a base 33, and two arms 31, 32. The arms 31, 32 include a circular arc-shaped bend 31a, 32a in the center, the center of which is in at point 0. The thickness h of the legs 31, 32 decreases from the bottom of the bend 31a, 32a towards their ends 31b, 32b. In the same zone, the width 1 of the arms increases from the bottom 25 of the bend towards their ends. The ends 31b, 32b have a flattening of approximately constant width and height. The width and height of the base and arms to the bottom of the bend 31a, 32a are also constant. 30 in the free state '(Fig. 1) the tangent plane 10 15 20 78131 • l3 78131 4 P passing through the base of the flatness creates an angle a equal to about 10 °, with the plane Q passing through the plane of the upper base 33. above thesis 33 and above point 0. In general, angle a is within the limits 3-112C. A trap of this design has arms that are very elastic at a point outside the bends 31a, 32a. The deformation of the arms of the tab is approximated by their rotation around the point 0. Figs. made of metal. The pad T has a shoulder 20 against which the rail R rests via an insulating plate 21, a recess 22 and a side shoulder 23 to support the base 33 via a washer 24 having a flange 24a which provides a side resistance to the tab 30. When mounting, the ends 31b, 32b of the arms fasten the foot of the rail R, preferably by means of a resistance plate 36 and an insulating plate 37. The fixing of the rail with a tab is carried out as follows. The sleeper is provided with a double-threaded pin 50 of a known type, on the end of which 50a a nut 51 is screwed. At the beginning of assembly (Fig. 3a), a stop ring 52 is placed on the pin 50. Then the tab 30 is placed with bends 31a, 32a directed towards on the bottom, with the ends 31b, 32bq resting on the plate 36 and the base 33 on the washer 24. A head 60 (Fig. 5) is placed on the spindle 50 containing an opening 60a and in the lower part of the surface 60b having a shape similar to the shape of a the top bend 31a, 32a with which it contacts. In the initial position, the ends 31b, 32b do not fully adhere to the plate 36. In the next phase of assembly, tfig. 3b) a nut 51 is screwed onto the threaded part 50a of the spindle 50. The ends of the arms 31, 32 bend and rest their entire surface against the plate 36. In the final stage (fig. 32a will contact the thrust ring 52. The diagram (FIG. 6) shows the deflection arrow F of the paw, expressed in mm, as a function of the clamping force S, expressed in kg. The lines A, B, C correspond to the individual assembly phases as shown in Figs. 3a, 3 "b, 3c. In the graph, the curve marked with a thick line shows the characteristics of the paw attachment according to the invention. The dashed line is shown for comparison. when using the known UZ-shaped claw, the diagram shows that for the same clamping force, the arrow of the bending of the tab according to the invention is greater. This is a major advantage. Moreover, according to the invention, obtaining the desired amount of clamping force is achieved very simply by The bend 31a, 32a is pressed against the stop ring 52 without the need for adjustments. The fastening device according to the invention also has other advantages, for example easy dismantling, good lateral seating of the rail, the possibility of electrical insulation and the possibility of a table In addition, the clamp according to the invention can be used in a device for fixing a rail on a floor containing a reaction element in the form of a head with wings, resting on a backing.
