Definitions

  • the invention relates to a composite panel element, in particular made of concrete, for gauge tracks.
  • Track lanes often replace wide, massive lanes. Due to their smaller width, the environment is less severed and thus less influenced by the environment.
  • Gauge railways replace the functionally necessary part of a solid roadway without having its disadvantages. They are mainly used for agricultural roads. You can use it as a single or double track, but also for pedestrian paths, bike paths and the like. to be used.
  • the track is produced from individual composite panel elements which are placed against one another with their abutting surfaces. Because of the butt joint, the elements can be moved tangentially along the butt joint to achieve a gradual change in direction of the track. The abutting surfaces can be provided with a ridge. These composite panels must also be laid on a firm underbed. Because if the subsoil yields elastically and there is a change in the inclination of adjacent plates when there is a traffic load, the tongue and groove of the ridge fill will be excessively stressed.
  • the invention has for its object to provide a composite panel element that can be laid on an elastic bedding and thereby allows greater vertical forces to be transferred to the adjacent element without overloading the butt joint construction.
  • a composite panel element with the following features: a) the abutting surfaces running transversely to the track direction have a curvature to form essentially circular-arc-shaped abutting joints, b) the convex abutting surface has a groove and the concave abutting surface has a tongue, c) the cross-sectional boundaries of tongue and groove are arc-shaped in a force transmission area and have a transition section with opposite curvature on both sides of the force transmission area, so that there is an elastic clamping in the butt joint between adjacent, similar elements laid in a composite on an elastic bedding, which permits an inclination difference between the adjacent elements that increases as the forces to be transmitted increase.
  • the elastic clamping which can be achieved with the aid of the arcuate cross-sectional boundaries permits a relative movement of tongue and groove while maintaining the clamping torque and the transfer of part of the traffic forces from the loaded element to the adjacent element, so that the traffic forces over a track section which is longer than one element , are transferred to the elastic bedding. If, in the case of large traffic forces, the loaded element sinks more into the elastic bedding, the neighboring element can follow this movement, even if the difference in inclination between the two elements is increased. Because of the arcuate cross-sectional limits of tongue and groove, it is ensured that the clamping forces are reliably transmitted even in the new relative position of tongue and groove. If the traffic load ends, the elements automatically return to their starting position under the influence of the elastic bedding.
  • the cross-sectional boundaries have a component in the direction of the track, which has the value 0 in a line of symmetry and increases continuously on both sides, it is ensured that as the vertical forces to be transmitted via the butt joint increase, the interacting surface areas of tongue and groove become an increasingly larger component Have track direction, so the forces can be transferred well. If the loaded element is moved out of the track level, it simultaneously exerts axial spreading forces on the two neighboring elements. The result is a resultant force with an axial component, through which the compressive strength of the concrete can be exploited during power transmission. The spreading forces also contribute to the provision in the event of relief.
  • the arches of the cross-sectional boundaries can have different shapes, in particular the shape of conic sections.
  • a particularly simple embodiment uses circular cross-sectional boundaries.
  • Computer calculation can be used to specify optimal shapes which are suitable for particularly large inclination differences between the adjacent elements.
  • the radius of curvature of the abutting surface should be 0.5 to 2 times the width of the element and should preferably be approximately equal to this width. If the radius of curvature is much larger, the clamping is transferred to a joint. With a much smaller radius of curvature, rigid clamping results.
  • the approximately circular arc-shaped part of the cross-sectional boundary has a radius which is approximately equal to half the height of the segment formed by the abutting surface.
  • the radii of curvature of the cross-sectional boundaries of tongue and groove in the force transmission area should be as equal as possible to one another and should not differ from one another by more than 3 mm. This gives a good fit on all inclinations.
  • a method for laying the composite panel elements according to the invention is characterized in that another element is deposited from the already laid track and then pressed against the front end of the track. As a result, the tongue and groove are brought into the desired rest position, to which they should return after the power transmission has ended.
  • a joint filler can be introduced before pressing.
  • Such an agent for example bitumen, does not hinder clamping and power transmission, but ensures that the joints are closed to the outside.
  • a tensioning device is attached on the one hand to the further element and on the other hand to the track path beyond the last installed element. This ensures that the further element is brought into the desired end position because the weight of at least two elements serves as counterforce.
  • the composite panel element 11 illustrated in connection with the figures consists of unreinforced concrete. It has a side length L, a width B and a height h.
  • One abutment surface 12 is convex, the other abutment surface 13 is concave, the radius of curvature is R.
  • the abutment surface 13 is provided with a spring 14, the abutment surface 12 with a groove 15.
  • the spring has an arcuate cross-sectional boundary 16, the groove has an arcuate cross-sectional boundary 17.
  • two composite panel elements 11 are put together with their abutting surfaces, they form, as shown in FIG. 2, a track S, whereby elastic joints 9 result in the butt joints 18, which exert a clamping or bending moment, a vertical force and a torsional moment on the neighboring elements 11 a and 11 b are able to transfer.
  • the composite panel elements lie on an elastic bedding 10, preferably directly on the existing earth level. If, for example, a wheel load P R rests on the element 11, then the elastic ground forces E not only have to bear the weight G of the plates, but also have to absorb this wheel load P R.
  • a butt joint 18 is formed from the concave butt surface 13 of the element 11 and the convex butt surface 12 of the element IIa, the tongue 14 entering the groove 15.
  • the cross-sectional boundary 16 of the tongue 14 has a radius r F and the cross-sectional boundary 17 of the groove 15 has a radius rN.
  • the radius r F1 being provided for the tongue
  • the radius rN1 being provided for the groove.
  • the cross sections considered here are each radial to the abutting surface 12 or 13.
  • the radii r F and rN of the cross-sectional boundaries of the tongue and groove are the same in the force transmission area K, while the transition radii r F1 and r N1 differ from one another.
  • the two arcuate cross-sectional boundaries 16 and 17 have a vertex in the middle, where the surfaces extend in the height direction of the elements. On both sides there is a component in the direction of the track, which increases towards the surfaces of the elements.
  • the resulting force Pz 2 now acts in an area U ' 2 which has shifted downward in relation to the area U 2 .
  • the force application area U 1 has also moved up to the point U ' 1 , where the resulting force P Z1 acts.
  • 5 schematically shows pressure wedge areas Di and D 2 which are intended to illustrate these relationships.
  • the cross-sections of tongue and groove are adapted to the concrete-specific strength properties taking into account the load parameters so that the joint construction can transmit the desired forces and moments.
  • Fig. 6 shows a top view of a track path S, which ends with the elements 11 c and 11 d. From this end of the track, the further element 11 e has been deposited on an undisturbed formation with the help of a laying device. After filling a joint material into the butt joint 18, a tensioning device is used, which is fastened to the element 11c in the region 21 and, on the other hand, bears against the element 11 in the region 22. By tightening this clamping device, the element 11 e is pulled close to the abutting surface of the element 11 d. Since here only the weight of an element 11 e has to be moved, but in the opposite direction the weight of two elements 11 c and 11 d form the abutment, no other anchoring is required.
  • Element 11 e laid in this way takes on its full function in the bond and is immediately resilient thanks to its elastic clamping and its shear and bending tensile properties.
  • a laying device and an element delivery vehicle can move on the track as construction progresses. After completing the backfill work, the track can then be opened to traffic immediately.
  • Fig. 6 also shows that the individual elements are each offset tangentially from each other. In this way, a curved track can also be produced without the static conditions in the butt joints 18 changing significantly.
