Abstract

A rail expansion device compensates for an expansion of a first rail with respect to a second rail. The rail expansion device joins the first rail to the second rail. The expansion device has a front connecting rail, containing a front end and a rear end, wherein the front end is configured for connecting to the first rail. A rear connecting rail, has a front end and a rear end, wherein the rear end is configured for connecting to the second rail. A splice joint is provided and configured for slidably connecting the rear end to the front end. The splice joint defines a continuous running surface from the front connecting rail to the rear connecting rail, wherein the continuous running surface has a variable longitudinal length configured for varying in function of a width of an expansion gap separating the front connecting rail from the rear connecting rail.

Dependent claims

A rail expansion device configured for joining a first rail to a second rail, the rail expansion device comprising:

a front connecting rail having a front end and a rear end, wherein said front end is configured for being connected to the first rail;
a rear connecting rail having a front end and a rear end, wherein said rear end of said rear connecting rail is configured for being connected to the second rail;
a splice joint configured for slidably connecting said rear end of said front connecting rail to said front end of said rear connecting rail, said splice joint defining a continuous running surface from said front connecting rail to said rear connecting rail, wherein said continuous running surface has a variable longitudinal length configured for varying in dependence on a width of an expansion gap separating said front connecting rail from said rear connecting rail;
and
the rail expansion device having a rail head width being constant from said front end of said front connecting rail until said rear end of said rear connecting rail.
