Abstract
In order to enable the use of highly resistant materials difficult to weld or not weldable at all for a stock rail (2), the tongue box for grooved rail switches, which includes a stock rail (2), a slide plate (5) and a side rail (3), whereby the side rail (3) and the slide plate (5) and a base plate (4) are welded together forming a box-shaped section with the stock rail (2), is designed in a manner that the stock rail (2) is connected with the box-shaped profile in a positive and force-transmitting manner by clamping pieces that are welded with the box-shaped section and/or the base plate (4).

A tongue box for grooved rail switches, which includes a stock rail (2), a slide plate (5) and a side rail (3), whereby the side rail (3) and the slide plate (5) and a base plate (4) are welded together forming a box-shaped section with the stock rail (2), wherein the stock rail (2) is connected with the box-shaped section in a positive and force-transmitting manner by clamping pieces that are welded with the box-shaped section and/or the base plate (4), wherein the clamping pieces include at least a flange sleeve (14) inserted through an opening (13) of a rail web (10) of the stock rail (2) and connected with the box-shaped section by a shrink weld, and a flange (16) of the flange sleeve (14) overlaps the opening (13) of the rail web (10) of the stock rail (2) on the external side facing away from the box-shaped section.
A tongue box for grooved rail switches, which includes a stock rail (2), a slide plate (5) and a side rail (3), whereby the side rail, (3) the slide plate (5) and a base plate (4) are welded together forming a box-shaped section with the stock rail (2), the stock rail (2) being connected with the box-shaped section in a positive and force-transmitting manner by clamping pieces that are welded with the box-shaped section and/or the base plate (4), wherein the clamping pieces include at least a flange sleeve (14) inserted through an opening (13) of a rail web (10) of the stock rail (2) and connected with the box-shaped section by a shrink weld, and a flange (16) of the flange sleeve (14) overlaps the opening (13) of the rail web (10) of the stock rail (2) on the external side facing away from the box-shaped section, with the side rail (3) and structural components of the welded box-shaped section being made of readily weldable structural steel, in particular steel having a strength value of 500 N/mm2, wherein the welded box-shaped section is comprised of supporting plates (11, 12) which are parallel in cross section and of the slide plate (5) welded with the supporting plates as well as the base plate (4) extending parallel with the slide plate, the side rail being welded with one of the two supporting plates (11, 12).
A tongue box for grooved rail switches, which includes a stock rail (2), a slide plate (5) and a side rail (3), whereby the side rail (3) the slide plate (5) and a base plate (4) are welded together forming a box-shaped section with the stock rail (2), the stock rail (2) being connected with the box-shaped section in a positive and force-transmitting manner by clamping pieces that are welded with the box-shaped section and/or the base plate (4), wherein the clamping pieces include at least a flange sleeve (14) inserted through an opening (13) of a rail web (10) of the stock rail (2) and connected with the box-shaped section by a shrink weld, and a flange (16) of the flange sleeve (14) overlaps the opening (13) of the rail web (10) of the stock rail (2) on the external side facing away from the box-shaped section, with the side rail (3) and the structural components of the welded box-shaped section being made of readily weldable structural steel, in particular steel having a strength value of 500 N/mm2, wherein the supporting members (9) are welded with the base plate (4) to laterally support the stock rail (2).
