  • FIG. 1 shows a rail car container 10 according to one embodiment of the disclosure.
  • the rail car container 10 comprises a first side wall 11 extending upwardly from a floor 12.
  • the side wall may be made from a single sheet (such as sheet steel), or may be made from multiple sheets which may be fixed together by welding, mechanical fasteners or the like.
  • the surface of the side wall may be generally smooth or may be profiled to include strengthening formations, such as corrugations or ridges as shown.
  • the container 10 also comprises a second opposite side wall 13 which in the illustrated form is of the same design and opposite end walls 14, 15 that connect to each of the side walls 11, 13 at respective opposite ends. In the illustrated form, the end walls have the same profile as the wide walls.
  • the rail container as illustrated is as a gondola for tipping or rotating discharge of material.
  • the floor 12 comprises a plurality of cross members 16 (sometimes referred to as “transoms” or “bolsters”) extending laterally across the floor, and a central beam (or sill) 17 that extends longitudinally along the container 10 between the end walls and parallel to the side walls.
  • the centre sill 17 forms a main structural component of the container and the cross members 16 extending between the side walls 11, 13 and are supported centrally on the centre sill 17.
  • the cross members 15 provide some stiffening to the floor of the container and as such have a structural function. In operation, there is significant loading imposed on the side walls 11, 13 in particular and also to some extent on the end walls 14, 15 when the container is carrying bulk material. The material tends to force the walls outwards, thereby causing the walls to bulge or otherwise deform. To improve the performance of the walls to accommodate these loads, the container 10 includes at least one support member 20 which strengthens the side walls.
  • the container has five such support members 20 disposed along and spaced from one another along each of the side walls 11, 13. It is to be appreciated that the number and spacing of the support members may vary from what is shown and will depend on the design loading on the side wall and the inherent strength of that wall.
  • the support members need to be adequately fixed relative to their respective side wall so as to resist outward bowing of that side wall. This fixing may be by welding or may be by mechanical fixing such as by mechanical fasteners or the like.
  • the support members may be integrally formed with their respective side wall.
  • the support members are disposed on the interior of the container. However, it is to be appreciated that they could be externally mounted.
  • Each support member 20 comprises a base portion 21 that engages one of the cross members 16 that forms the floor 12 of the container and a body portion 22 that extends upwardly from the base portion along the inner surface of its respective side wall, generally to the top of the side wall as shown in the illustrative embodiment.
  • the base portion 21 is fixed to one of the cross members 16, typically by welding, but it may also be fastened using other means including mechanical fasteners.
  • the base portion 21 is wider than the body portion 22 which means that when stress due to bulk material loading in the rail car container is transferred through the body portion to the base portion and into the floor of the container, the wider base portion 21 provides the support member 20 with sufficient strength and stiffness to
  • Each support member 20 also comprises a transition portion 23 that widens between the body portion 22 and the base portion 21, defining a curved inner edge 24.
  • the transition portion 23 enables a smooth transition between the body portion 22 and the base portion 21 so that loading is more evenly distributed through the support member 20 and avoids undue stress concentration within parts of the member.
  • each support member 20, including the base member 21, the body portion 22 and the transition portion 23, is in the form of a plate member of generally unitary thickness.
  • the plate member provides the required strength and stiffness to support the side wall whilst being light weight, small, easy and cost effective to manufacture.
  • the support member could be in other forms that provide a base member that is wider than the body portion.
  • the support member could comprise a hollow or open section having a flared lower portion that comprises a base portion.
  • the support member 20 also comprises recesses or cut-out portions 30 formed in an outer edge of the of the body portion 22. The recesses 30 are provided so that support member fits around and accommodates ridges 31 formed in the side wall 11 for strengthening of that side wall.
  • the support member 20 may have more or less recesses as shown in Figures 1-3. In other embodiments, the side wall may be flat and the support member has no recesses.
  • each connecting member 40 comprises a generally trapezoidal shaped hollow member comprising first and second panels 41, 42 that are interconnected and spaced apart by side panels that provide engaging surfaces 43, 44 for one of the side walls and one of the end walls of the container 10 to engage and connect.
  • the first panel 41 is wider than the second panel 42 which confers the trapezoidal shape on the connecting member 40.
  • the shape of the connecting member 40 results in the container 10 having chamfered corners.
  • each connecting member is disposed at generally 90" to each other. They present surfaces that are perpendicular to the longitudinal extent of the side and end walls respectively.
  • the engaging surfaces 43, 44 provide a surface against which the side and end walls can abut respectively, whatever their shape.
  • the side and end walls can be readily joined by welding for example to the connecting member 40 and thus to each other (via the connecting member).
  • the side and end walls are provided with corrugations or ridges for strengthening and stiffening of the walls. With this shaping of the walls, they would ordinarily be very difficult to join at the corners of the container 10.
  • the connecting members 40 joining of the walls and thus construction of the container 10 is greatly eased.
  • the connecting members 40 strengthen and stiffen the corners of the container 10.
  • the number and arrangement of the positioning and spacing of the ribs and supports may vary.
