The invention provides a system for fastening a rail in place and a rail fastener which, while being simple to install, allow a large measure of freedom in the production of the components required and at the same time have great practical utility. To this end a system according to the invention for fastening a rail to a fixed bottom support: a base plate produced from a plastics material, an intermediate layer which is arranged between the base plate and the fixed bottom support, a carrier plate which is arranged between the intermediate layer and the bottom support, a resilient member to hold down the rail which is to be fastened in place, a clamping bolt to brace the resilient member against the base plate, and a fastening member for fastening the base plate to the fixed bottom support.
摘要:
A base plate for fastening a rail to a fixed bottom support, there being formed in the base plate an opening, which runs from its upper side to its underside, for an eccentric sleeve, which eccentric sleeve is adjustable in rotation in the opening for a sleeve, about an axis of rotation defined by a fastening member inserted through the eccentric sleeve, to allow changes in the position of the base plate. In the opening for the sleeve are markers for indexing for fixing the position in rotation of the eccentric sleeve, the markers spaced from one another such that, an adjustment of the eccentric sleeve in rotation between two adjacent markers for indexing involves a step-by-step change in the position of the base plate by a defined amount.

A system for fixing a rail onto a foundation comprises a spring element, which can be clamped against a foundation by means of a clamping element, with at least one spring arm and an adapter piece. The adapter piece has a holder, in which an end section of the spring arm of the spring element sits, and a contact surface section formed at its periphery, with which, when the system is assembled, it sits on the rail foot of the rail to be fixed, such that the elastic retaining force exerted by the spring element is transferred onto the rail foot.
