Tension clamp and fastening point for the fastening of a rail to the ground

A tension clamp for elastically holding down a rail for rail vehicles, the rail comprising a foot, a web that is supported on the foot and a rail head carried by the web, the tension clamp comprising:

• a loop-shaped central section, with two legs and a base section that connects the legs to one another, wherein a free end face of the base section faces a front face, a free upper face of the loop-shaped central section faces an upper face of the tension clamp and the legs of the loop-shaped central section face with their ends, which face away from the base section, face a rear face of the tension clamp,
• two torsional sections, one of which in each case is connected to an end of one of the legs of the loop-shaped central section that faces away from the base section, wherein the two torsional sections lead away laterally in an outwards direction in each case starting from the leg that is allocated to the two torsional sections respectively and wherein the torsional sections have a supporting zone on a lower face by means of which the tension clamp is supported on a component that bears them during use;
• and
• two supporting arms, one of which in each case is connected to an end of one of the two torsional sections that faces away from the allocated leg of the loop-shaped central section, wherein the supporting arms run in the direction of a front face of the tension clamp and in each case have a spring section curved towards an upper face of the tension clamp and a support section that ends at a free end of the supporting arm, the free end of which support section has a supporting zone by means of which the supporting arm in question is supported on the foot of the rail to be fastened during use,
• wherein the support sections of the supporting arms and the free ends thereof each point laterally outward relative to the loop-shaped central section of the tension clamp such that when the tension clamp is viewed from above straight lines that connect the center of the supporting zones of the supporting arms to the center of the supporting zone of the torsional section allocated to the respective supporting arm intersect in an area located on the rear face of the tension clamp, and
• wherein for a distance, AS, measured parallel to a symmetrical axis of the tension clamp between the center of the supporting zones of the supporting arms and a point of intersection of the straight lines which connect the center of the supporting zones of the supporting arms respectively to the center of the support zones of the torsional section allocated to the respective supporting arm and for a distance, AG, that is also measured parallel to the symmetrical axis between the supporting zones of the supporting arms and the centers of the supporting zones of the torsional sections, the following applies:
• 1.2×AG≤AS≤1.8 AG.
