Problems solved by technology

However, as with all pre-arranged railroad ties, the sealant must also be placed under the railroad ties, which are located at a greater or lesser distance above the support layer, thus creating difficulties and the impossibility of continuous simultaneous pouring of railroad tracks of railroad tie netting The ties, on the contrary, have to be done in sections, otherwise there is no guarantee that the sealant will fill the space under the railway ties and that the air present there cannot form air pockets

Embodiment Construction

[0011] The double-block concrete railway tie of the present invention comprises two separate blocks 1 connected by a continuous reinforcement 2 located between the two blocks 1 . In the example shown, the reinforcement 2 consists of two lattice supports 3 which are parallel to each other and which can be formed with each of three longitudinal iron bars 4 which correspond to the axes of the railway crossties. Parallel, and connect these serpentine curved tubes 5 or diagonal members that can be broken down into individual triangles. On the outer front side 6 the trellis support 3 protrudes from the block 1 and is still on the outer front side 6 and there it is well in the sealant 8 which extends up to the plane 7 and additionally the protruding part of the trellis support It can also be fitted with supports and alignment pieces.

[0012] According to the invention, the blocks 1 are constructed in such a way that they are so thick that they can be glued directly to the support l...

Abstract

A two-block concrete railroad tie for a fixed rail carriageway with an at least partially continuous reinforcement, which is exposed between the blocks and, after alignment, engages the sealing compound over a supporting layer, becoming anchored in it, the blocks being provided with a mounting surface, which is shortened in the longitudinal direction and from which slanting side surfaces extend upward at least at the front side.

Description

technical field [0001] The invention relates to a double-block concrete railway sleeper for securing the trackway with an at least partially continuous reinforcement element located between the blocks and which, after alignment, incorporates a sealant on the support layer to secure the sleeper on the support layer. Background technique [0002] Many such double-block concrete railroad ties with different types of continuous reinforcement have been proposed and different types are available on the market. Such a railway tie and the method for installing and securing a railway with such a tie are described in German patent document DE19653858A1. For installation, concrete railroad ties carrying rails or auxiliary rails are pre-mounted to the rails, adjusted in position and height on a support layer, typically a layer of lean concrete without reinforcement, and finally embedded in a sealant. With the exception of the embodiment in which part of the reinforcement protrudes fro...
