Definitions

  • This invention relates to a device for use in supporting and fastening rails to a ground or other support surface.
  • Cranes for dockyards and container terminals etc. run on steel rails which are fastened to the ground or other support structure by a plurality of rail fastening devices arranged at intervals along the rail.
  • the foot of a typical rail comprises a pair of oppositely-directed longitudinal flanges, against which the fastening devices clamp to hold the rail in-situ.
  • WO2015/165790 discloses a typical rail fastening device that can be anchored to the ground or other support surface at intervals of say 600mm along the rail on opposite sides thereof. Each device comprises a displaceable clip for engaging the rail.
  • opposing pairs of devices are fixed to individual metal soles set at intervals along the rail.
  • Continuous soleplates are generally manufactured using 3m or 6m elongate lengths of steel having a thickness of 20mm to 25mm and a width to suit the rail application, typically 400mm to 600mm. Rail fastening device are then bolted or welded to the plate and holes for jacking bolts and ground-engaging bolts are drilled.
  • Known continuous soleplates are mounted end-to-end under the rail with a 10mm to 20mm gap therebetween to allow the plates to be manoeuvred into position during the installation, to allow space for a thermal expansion, and also to allow grout to flow between the ends of the plates.
  • an elongate elastomeric rail pad is disposed between the rail and the plate. If the gap between the plates is too large, the rail pad supporting the rail can undesirably drop down into the gap due to lack of support. Whilst this in itself is not a problem, the rail pad can be damaged by the edge of the soleplates due to stress concentrations.
  • each elongate soleplate is fastened to the ground or other support structure by anchor bolts but a problem of leaving a gap between the plates is that the anchor bolts at the ends of the plates have to be spaced irregularly compared with the other bolts that are spaced regularly with respect to the clips. Whilst this does not generally create a problem when manufacturing the soleplates, it can be a problem if an installer is constructing a concrete foundation and casting in bolts or bolts fixings because they have to follow this irregular spacing, which has led to mistakes being made.
  • a rail support and fastening device comprising an elongate soleplate having complementary joint portions at its respective opposite ends for engaging respective complementary joint portions of adjacent devices mounted end-to-end therewith.
  • a plurality of devices are laid end-to-end such that the complementary joint portions of adjacent soleplates engage each other. This avoids the risk of damage to the rail pad since the gap is eliminated and the joint helps to keep the ends of adjacent soleplates at the same level. Also, the elimination of the gap allows apertures to be formed at regular intervals for receiving the ground anchors.
  • the complementary joint portions may comprise respective portions of a lap joint and/or a tenon joint.
  • each portion of the lap joint comprises a major face arranged to register face-to-face with the major face of the complementary joint portion of an adjacent device, each major joint face extending in a plane which lies parallel to planes defined the major surfaces of the soleplate.
  • the complementary joint portions of adjacent soleplates can be partially overlapped in a manner where vertical movement is prevented and where horizontal movement is permitted to allow for expansion and contraction.
  • Apertures may extend through the complementary joint portions for receiving fastenings for securing the devices to the ground or other support structure.
  • the fastenings also help to keep the joints together.
  • the aperture in at least one of the complementary joint portions may be elongated in the direction of the longitudinal axis of the soleplate, to allow some flexibility in the positioning of adjacent devices and to allow axial expansion and contraction.
  • Apertures may be formed in the soleplate for mounting clips arranged to engage the rail.
  • a plurality of raised formations may be disposed on the soleplate, each formation providing a base for mounting a clip arranged to engage the rail. The latter arrangement has the advantage of reducing the cost of fabrication by incorporating clip bases into the soleplate and eliminating the need to drill and tap apertures.
  • the soleplate may be formed with a formation adapted to engage a complementary formation on a rail pad.
  • the complementary formations may comprise a rib and a channel.
  • the elongate soleplate may be a one-piece member.
  • the elongate soleplate may comprise a plurality of members interconnected end-to-end. The members may comprise formations at its respective opposite ends for engaging respective complementary formations of adjacent members mounted end-to-end therewith.
  • One of the members may be provided with said apertures for mounting clips arranged to engage the rail or said raised formations.
  • Said member may be provided with said formations adapted to engage complementary formations on a rail pad.
  • Said member may have a width which is greater than the width of an adjacent member of the soleplate.
  • the or each member may formed of metal, for example by casting. We have found that using more than one member for each soleplate helps to avoid the limitation that casting have on the length of a one-piece soleplate.
