The invention relates to a rail (10) fixing device with the aid of a tensioning clamp (22, 24) extending from a holding element (26, 28) and is removably arranged on a ribbed plate (14) on which the rail base is mounted. Said ribbed plate is placed on an elastic intermediate layer (30) which is maintained in a required prestressed state by the holding element.

An anchoring device (4), for retaining a spring rail clip (3) in a railway rail fastening assembly, comprises an anchoring stem part (40), fixed to a rail foundation (2) when the device is in use, and a clip-retaining head part (41), engageable with the said anchoring stem part (40), for retaining the spring rail clip (3), the height of the rail clip (3) relative to the rail foundation (2) being determined by the position of the clip-retaining head part (41) of the device (4) relative to the anchoring stem part (40) thereof. Adjustment of the position of the said clip-retaining head part (41) relative to the said anchoring stem part (40) is effected by translational movement of the clip-retaining head part (41). In a method of adjusting lateral rail position in a rail fastening assembly using such an anchoring device (4), the clip-retaining head part (41) of at least one of the anchoring devices (4) in the rail fastening assembly is replaced by another clip-retaining head part (41') having an overall thickness, at a portion lying between the rail foot and the anchoring stem part (40) of the device (4), which differs from that of the first-mentioned clip-retaining head part (41).

The invention relates to an elastic tensioning clamp made of spring steel comprising a middle part (14; 12) with two inner limbs (12) and with loops (16), which are connected to the inner limbs (12) and which extend up to the free ends (18) of the tensioning clamp (10). The tensioning clamp is characterized in that the free space located between the middle part (14; 12) and the loops (16) in the vicinity of the free end (18) is selected such that the loop (16) of the tensioning clamp (10) cannot enter inside the loop of a structurally identical tensioning clamp.

The present invention relates to a rail clip fixing implement, and in particular to a rail clip fixing implement capable of pressing a flange portion of a rail embedded in a PC tie on a gravel railway and fixing the rail. The rail clip fixing implement according to the present invention includes a fixing portion having an elongated hole having a horizontal cross-section length into which an insertion portion of a rail clip is inserted, an embedded portion downwardly extended from a lower portion of the fixing portion and embedded in the tie, and a support horizontally extended between the fixing portion and the embedded portion for supporting a lower portion of the flange portion of the rail on the surface of the tie.
摘要:
The present invention relates to a rail fixing clip of a railway for directly pressurizing a lower flange portion of a rail of a railway installed in a rail tie or in a concrete railway and tightly fixing to a tie or a rail support for thereby preventing an escape of a rail of a railway, and in particular to a rail fixing clip of a railway having a durability significantly enhanced in a state that more than two separated points are supported. The rail fixing clip of a railway includes an insertion portion including a couple-of-force portion of a straight line-shaped rod and a hinge portion extended from one end of the couple-of-force portion and arranged in parallel with respect to the couple-of-force portion above the couple-of-force portion, and a support portion including a co-working portion extended from the hinge portion at a certain horizontal distance in parallel with respect to the hinge portion and a pressing portion extended from the co-working portion and arranged in parallel with respect to the co-working portion below the co-working portion for pressing the upper surface of the flange portion of the rail of the railway.
