Description

  The present invention relates to a line support layer which forms a base for rails of a line in the form of a continuous body of a plurality of line support layers arranged in succession and has a groove-like channel on the upper surface for receiving the rails of the line.

  A track support layer of the kind described above replaces the sleepers as the base of the rails of the tracks, thereby lowering the maintenance costs normally required than tracks supported by sleepers. This is because this layer hardly sinks into the road bed even when a large load is applied. Furthermore, the upper surface of such a track support layer can directly form a traffic surface for road traffic and / or pedestrians (Verkehrsflaeche).

  The object of the present invention is to provide a line support layer of the kind described at the beginning, which can be used to form a base for supporting the rails of such lines when the direction of the line direction (Verlaufsformen) is different. There is to do.

  The line support layer of the type defined at the beginning constructed according to the present invention has an isosceles trapezoidal shape when viewed in plan, and the isosceles trapezoidal leg is The direction of the two end faces (Verlauf) of the support layer is defined, and each of the end faces faces the line support layer adjacent to the line support layer in the continuum of the line support layers, isosceles trapezoidal, The parallel side surfaces define the directions of the two side surfaces of the line support layer extending in the longitudinal direction of the line, and the grooves are provided to receive the rails extending from one end surface to the other end surface of the line support layer. The channel has a bent or arched direction, and the cross section of each channel when viewed from the end face of the line support layer has a channel side surface due to the bent or arched direction of the channel. The constricted part on the appearance of the side part is caused by Each of the channels is adapted to receive a cross-section of the rail therein so that a straight rail can be inserted into each of the bent or arcuate channels and is provided to receive the rail. The concave surface in the direction of the side faces the shorter side surface of the line support layer when viewed in plan. This configuration easily achieves the above-described object. Such a line support layer can be used as a base of a line extending in a straight line or as a base of a line extending in an arch shape, so that the configuration of a single line support layer is actually important. The range of a certain radius of curvature can be clarified. Here, the base of the linearly extending line may be a continuous body of the line support layer having the above-described configuration, and the plurality of continuously disposed layers of the above-described continuous body are perpendicular to the layer surface. Is rotated 180 degrees with respect to the geometric axis extending to In order to form the base of the arch-like portion of the track, such a line support layer can be arranged as a continuous body that is arranged in the same direction as each other, and the continuum of this continuous body extends outward in an arch shape. The side edges are formed by the long side edges of the individual layers, and the arched inner edge of the continuum is formed by the short side edges of the individual layers.

In this regard, in an advantageous embodiment, the side surface of the channel provided to receive the rail is downward from the constriction located in the region of the upper surface of the line support layer, initially outwardly with respect to the center of the channel. This is realized if it extends so as to incline and then descends downward toward the bottom of the channel. In a variation having a wide bottom surface of the channel provided to receive the rail, the side surface of the channel provided to receive the rail is channeled downward from a constricted portion located in the region of the top surface of the line support layer. Inclined outward with respect to the center of the channel and extends so as to descend toward the bottom surface of the channel. In another advantageous embodiment, which is also advantageous for accommodating a relatively high rail mounting clamp, the side of the channel provided to receive the rail is from a constricted portion located in the region of the top surface of the line support layer. Downward, it is characterized in that it initially extends horizontally outward with respect to the center of the channel and then extends downwardly toward the bottom of the channel. In another variation on the cross section of the channel provided to receive the rail, the side surface of the channel provided to receive the rail is below the constricted part located in the region of the upper surface of the line support layer, It extends to the bottom by spreading in an arch shape with respect to the center. This variation provides an advantage with respect to the load bearing capacity of the upper surface of the line support layer that serves as a passing surface.
