Definitions

  • the invention relates to a sleeper mold for the production of concrete sleepers for railroad tracks, comprising a mold base with at least one receiving opening for insertion of a support member and at least one contact point in association with the receiving opening, on which the support member in the inserted state directly or indirectly supported on the mold bottom in a predetermined position is, and a receiving opening substantially defining edge region.
  • the support elements In the production of concrete sleepers with embedded support elements, such as so-called Pandrol fast clips, for fastening railroad tracks, it is essential that the support elements must assume predetermined relative positions at the threshold corresponding to the respective track system for which the concrete sleeper is intended. Thus, the support elements must be matched in their position at the threshold to the track of the track in question. If the rails of the track in each case fastened by mediation of at least one support element on one side of the rail and at least one support element on the other side of the rail at the threshold, so determine the manner of rail fastening and the formation of the rail itself, such as the transverse dimension a rail foot, requirements for the relative position of a rail associated support members.
  • Such a threshold form is for example from the WO 01/00929 A1 known.
  • a threshold form so far problems may arise that on the one hand freshly filled concrete vapors can penetrate into the region of engagement between the support member and the mold bottom and thereby later the de-scaling of the threshold is difficult and on the other hand, the contact point of the mold bottom during continuous operation of the device for the production of Concrete sleepers are exposed to heavy wear.
  • the present invention has for its object to provide a sleeper mold for the production of concrete sleepers for railroad tracks, which can reduce the wear of the contact points on the mold bottom.
  • the at least one contact point in association with the receiving opening, on which the support member is supported in the inserted state directly or indirectly to the mold bottom in a predetermined position, from one to the Mold bottom forming material wear-resistant material is performed to the z. B. to reduce wear occurring in this area during a continuous operation.
  • the use of hard metal flakes is regarded as being particularly preferred as contact points.
  • the mold bottom has a number of edges of an elastic material at least partially encircling the receiving opening in such a way that when the holding element is inserted into the receiving opening, the sleeper mold in the region of the receiving opening prevents it from escaping of not fully cured concrete from the sleeper shape between the edge region and the support element and / or against entry of incompletely cured concrete in an engagement region between the mold bottom and the support member is substantially sealed.
  • the elastic material preferably forms at least one elastic lip, which comes into contact with the retaining element inserted into the receiving opening.
  • an elastic material in particular an elastic lip
  • the latter advantage is particularly important in immediate Abschal compiler in which a concrete sleeper is de-activated immediately after filling and compacting of the concrete, since in this method a force on the support elements when lifting the sleeper form of the concrete sleeper must be kept as low as possible to a displacement of the support elements To avoid as far as possible from their desired position in the not yet fully cured concrete.
  • At least one contact point will be part of the edge region or define the receiving opening together with the edge region.
  • the at least one receiving opening, the at least one contact point and optionally the edge or edges are part of an exchangeable frame which is mounted or mountable in association with an opening of the mold bottom.
  • An advantage of this embodiment is z. B. that the sleeper shape can be adapted in a simple manner for use with different types of support elements by a given frame with a correspondingly adapted receiving opening, d. H. appropriately trained contact points and possibly edges, can be mounted on the mold bottom.
  • it is considered an advantage of the interchangeable frame that this can be easily replaced in the event of wear occurring in continuous operation of the device against another frame, for example against a still unworn frame.
  • a mold base section having the receiving opening or the exchangeable frame can be separated from a remainder of the sleeper mold.
  • This can advantageously be used to leave at least this mold bottom portion at the not yet fully cured threshold at a Entschal compiler, in particular a partial or immediate Abschal compiler.
  • a partial or immediate Abschal compiler is for example in the WO 01/00929 A1 described and allows a partial deforestation of a not yet fully cured threshold, leaving behind the support members receiving mold bottom portion, on the one hand a quick reuse of the switched-off part of the sleeper shape to achieve and on the other hand to ensure the necessary stability of the position of the support elements during the curing of the concrete.
  • At least one abutment element associated with the mold bottom can be provided in the region of the receptacle opening which forms an abutment station offset outwards from the mold bottom, on which the retainer element is supported in a predetermined position directly or indirectly on the mold bottom in the inserted state.
  • Such an abutment point may be provided in addition to the abutment points substantially lying in the plane of the mold bottom in order to additionally stabilize the mounting element in its inserted state.
  • the bearing surface of the described contact element which is offset outwardly relative to the mold bottom is made of a material which is more resistant to wear relative to a material forming the mold bottom and can advantageously be formed by a hard metal chip.
  • Fig. 1 shows a Pandrol support member 112 for supporting rails, not shown, with a Garrungselementfuß 113, which is embedded for attachment of the support members 11 2 in the concrete 110 of the threshold 111.
  • the support member 112 further includes shoulders 116 which serve to secure the rails, not shown, to the sill 111.
  • the support member has approximately vertically middle position four projecting lugs 119a to 119d, which come in the inserted state of the support member 112 with a hard metal flake bearing pads 121 a to 121 d a threshold form, in this case specifically a frame 131 of the sleeper shape, come into contact.
  • the Pandrol holding member 112 is formed with a protruding part 123 that abuts on a portion 143 of the frame 131.
  • Fig. 2 shows the mentioned frame 131 with two inserted therein, each having a receiving opening 133 for receiving a respective support member 112 containing intermediate frame 134.
  • the frame 131 has at the point indicated by 135 a division to according to proposals of the WO 01/00929 A1 to allow a review and correction of the relative position of the embedded support members 112 in the not yet fully cured concrete 110.
  • the graduation 135 of the frame 131 permits the adjustment or correction of the dimensions a, b and c of importance for maintaining the track gauge or for adapting to a specific track system according to FIG WO 01/00929 A1 ,
  • the receiving opening 133 of the intermediate frame 134 is defined by the contact points 121 a to 121 d and by the receiving opening 133 partially encircling and the edge region of the receiving opening 133 forming edges 137. According to these edges 137 exist an elastic material and are in the embodiment of Fig. 2 designed as elastic lips 139.
  • Fig. 3 shows a sectional view of the frame 131 receiving the mold bottom portion 141 of a sleeper mold according to the invention and two schematically indicated support members 112 in the inserted state.
  • the mold bottom 141 and the frame 131 are in Fig. 3
  • the illustrated state in contact with the concrete 110 placed in the sleeper mold and the support element feet 113 are embedded in the concrete 110 of the threshold 111 to be produced. In this state, for example, relies in Fig. 3
  • the support member 112 is supported in the in Fig.
  • Fig. 3 illustrates how the elastic lips 139 of the edge region of the receiving opening 133 rotate around the support element 112 and come to a line system with it at the locations indicated by 147. This prevents liquid concrete slurry from penetrating into the region of engagement between the support member 112 and the intermediate frame 134, or may exit the sleeper mold through this region.
  • the inventive sleeper mold and its developments thus provide engagement between a mold bottom portion 141 or frames 131, 134 and a support member 112 which, on the one hand, minimizes dislocation of the support member 112 while jigging the sleeper mold for the purpose of compacting the concrete 110 therein , at the same time largely prevents the penetration of liquid concrete sludge in the area of engagement and on the other hand facilitates the release of the mold bottom portion of the support member 112 when removing the sleepers in the partial or immediate Abschalvon.
  • the invention is not on the in the FIGS. 2 and 3 illustrated embodiment limited.
