Embodiment Construction

[0072] Tension clamps 1 , 50 for fixing the rail S supported on the base U (here formed from concrete sleepers), formed in one piece from spring steel wires in a curve without dead bends 1 , 50 with respect to the support to the base U The layer N1 perpendicular to the plane 2 is mirror-symmetrical. The tension clips respectively have ring-shaped, in plan view ( Figure 4 ) is a U-shaped middle section 3, which has two parallel and spaced apart arms 4, 5 and a rail foot corresponding to the track S to be fixed, connecting the two arms 4, 5 to each other The semicircular connection section 6 of F.

[0073] A laterally protruding torsion section 9 , 10 is connected to each arm 4 , 5 of the central section 3 via a first transition section 7 , 8 bent at 90°. The torsion sections 9 , 10 point in the opposite direction to the middle section 3 and form an angle α of approximately 90° with the legs 4 , 5 of the respective associated middle section in plan view.

Abstract

A tension clamp (1) for fastening a rail (S), having a central portion (3), having at least one torsion portion (9, 10) which extends in the lateral direction from the central portion (3), having at least one transition portion (7, 8) which adjoins the torsion portion (9, 10), and having at least one holding arm (13, 14) which is connected to the transition portion (7, 8) and of which the end portion (19, 20), which is assigned to the free end of the holding arm (13, 14), is aligned in an angled manner in relation to the torsion portion (9, 10) as seen in a plan view of the tension clamp (1), wherein, on the angled end portion (19, 20) of the holding arm (13, 14), there is formed a support region (21, 22) which extends over the length of the end portion (19, 20), and the end portion (19, 20) is angled in relation to a part (15, 16), which adjoins said end portion, of the holding arm (13, 14) such that, when the tension clamp (1) is in the fully installed state, the support region (21, 22) is supported over its entire length (Le) in a linear manner on the associated surface (O) of the rail foot (F) of the rail (S) to be fastened.

Description

technical field [0001] The invention relates to a tension clamp for rail fixing, the tension clamp has: a middle section; at least one torsion section branching from the middle section to the side; at least one transition section connected to the torsion section As well as at least one clamping arm connected to the transition section, the end section of the clamping arm corresponding to the free end of the clamping arm, viewed from a top view of the tensioning clamp, is bent in the opposite direction of the torsion section. Tension clamps of this type are usually bent in one piece from spring steel. [0002] The invention also relates to a system for fixing a rail having a rail foot, a web on the rail foot and a rail head, the system having a guide plate, a tension clip fixed on the guide plate and a Clamps for base clamp tension clamps. Background technique [0003] Such tension clips and systems are known from DE 10 2007 046 543 A1. In the known system, a tension clip i...
