Definitions

  • the present invention relates to a floor structure for a transport container and more particularly to a floor structure according to the preamble of claim 1.
  • the present invention further relates to transport container and more particularly to a transport container according to the preamble of claim 15.
  • Transport containers and so called general transport containers or dry transport containers, are used for transporting different kinds of cargo.
  • the transport containers conventionally comprise a support frame and floor structure, wall structure and roof structure attached and supported to the support frame.
  • the floor structure usually comprises separate support beams attached to the support frame and such that they extend in the transversal direction in relation to the longitudinal direction of the floor structure.
  • the support frame is usually provided from tubular elements and the support beams from I-beams or the like.
  • a floor surface is provided by one or more thick plywood boards installed on the support beams. The plywood boards are thick enough such that they stiffen the floor structure and carry the load caused by operations performed on it. From the underside the floor structure is typically open such that the support beams are exposed.
  • the floor structure further comprises one or more, usually two, gripping part channels arranged to receive a fork of a forklift loader for moving the transport container.
  • gripping part of a relocation device is a fork of a forklift loader.
  • the gripping part channels are provided to underside of the floor surface, plywood board, such that forklifts may be inserted and remove from the gripping part channels from the side of the transport container.
  • the gripping part channels are conventionally been longitudinal casings with rectangular cross section which have been attached to the bottom surface of the plywood board.
  • the problem with the prior art transport containers and especially floor structures thereof is that the lifetime of the plywood boards is limited. Worn or otherwise damaged surface sheets may even lead to accidents during loading the container. Thus the plywood boards have to be regularly replaced. Replacing the plywood boards decreases the effective operating time and increases maintenance time. Furthermore, the used plywood is hazardous waste and which has to be specially treated. Another problem with plywood is that the boards have to be thick, for example in some applications boards with 28 mm thickness are used, for reaching adequate stiffness and impact strength. Accordingly there is need to replace the plywood boards with more durable materials without considerably increasing the weight of the floor structure.
  • the plywood boards have been replaced with metal sheets, especially steel sheets for providing the floor surface of a transport container. However the thick plywood has provided structural height and stiffness to the floor structure.
  • An object of the present invention is to provide a floor structure for transport container and a transport container so as to overcome or at least alleviate the above mentioned prior art problems.
  • the objects of the invention are achieved with a floor structure according to the characterizing portion of claim 1.
  • the objects of the invention are further achieved with a transport container according to the characterizing portion of claim 15.
  • the invention is based on the idea of providing for a transport container a floor structure which comprises a first surface layer manufactured from metal sheet.
  • the first surface layer comprises a top surface forming a floor surface and a bottom surface.
  • the floor structure is also comprises a support arrangement for supporting the first surface layer from the side of the bottom surface.
  • One or more gripping part channels are further arranged to the side of the bottom surface of the first surface layer for receiving a griping part of a relocation device.
  • the gripping part channel comprises a first and second side wall protruding from the bottom surface of the first surface layer and having a first side end connected to the bottom surface of the first surface layer and a distal second side end, the first and second side walls being arranged to form the gripping part channel between them.
  • the floor structure further comprises one or more oblique gripping part channel supports provided adjacent to and in direct or indirect connection with gripping part channel for providing additional support for the gripping part channel.
  • the gripping part support channel forms gripping location which is stiffened with the gripping part channel supports provided to the gripping location and adjacent to and in direct or indirect connection with gripping part channel.
  • the gripping part channel supports may be connected to the gripping channel or the side walls of the gripping channel or to the first surface layer or to the support structure for providing additional support for the gripping location and the gripping part support channel.
  • the gripping part channel support are attached or connected to the gripping part channel and particularly to the side walls of the gripping part channel such that the first and second side walls of the gripping part channel are supported to the floor structure with gripping part channel supports.
  • the gripping part channel supports are provided to extend from the gripping part channel structure and connected to the floor structure for supporting the gripping part channel structure.
  • the gripping part channel supports may extend in oblique direction in relation to the first surface layer or the first and second side walls or both the first surface layer and the first and second side walls.
  • the one or more gripping part channel supports may be arranged between the first side wall and the first surface layer or between the first side wall and the support arrangement or between the first side wall and a second surface layer provided under the support arrangement for forming a metal sandwich panel, such as steel sandwich panel, in which the support arrangement forms the core of the metal sandwich panel between the first and second surface layers outside of the gripping part channel.
  • the one or more gripping part channel supports may be arranged between the second side wall and the first surface layer or between the second side wall and the support arrangement or between the second side wall and a second surface layer provided under the support arrangement for forming a metal sandwich panel, such as steel sandwich panel, in which the support arrangement forms the core of the metal sandwich panel between the first and second surface layers outside of the gripping part channel.
  • one or more gripping part channel supports may be arranged between the first surface layer and a second surface layer provided under the support arrangement for forming a metal sandwich panel in which the support arrangement forms the core of the metal sandwich panel between the first and second surface layers or between the first surface layer and the support arrangement between the support arrangement and a second surface layer provided under the support arrangement for forming a metal sandwich panel in which the support arrangement forms the core of the metal sandwich panel between the first and second surface layers.
  • the gripping part channel supports are arranged to extend from the first surface layer, or second surface layer, or the support arrangement and the first and second side wall respectively in an angle which is less than 90 degrees in relation to the relation to the first surface layer or the first and second side wall.
  • the floor structure further comprises one or more first gripping part channel supports arranged between first surface layer, or the second surface layer, or the support arrangement and the first side wall, and one or more second gripping part channel supports arranged between first surface layer, the second surface layer, or the support arrangement and the second side wall, the one or more first and second gripping part channel supports arranged to extend in oblique direction in relation to the first surface layer or the first and second side wall for supporting the first and second side walls to the first surface layer.
  • the floor structure and particularly the structure of the gripping part channels, provides a gripping part channel with increased load-bearing capacity together with a floor surface provided with metal sheet.
  • the oblique gripping part channel supports distribute the loading subjected to the floor structure during moving the transport container with a relocation device to larger surface area of the floor structure. Therefore, the bending of the floor structure having substantially thin metal surface sheet may be decreased when the transport container is moved with a relocation device. This further decreases damages of the floor structures and transport containers caused by moving the transport containers with forklift loaders.

  • the support arrangement comprises a floor frame 7, which is part of the support frame 5 of the transport container 1.
  • the support arrangement further comprises separate beams 10 provided on the underside of the first surface layer 8 and shown with dotted lines figure 2B .
  • the beams 10 are attached to the floor frame from their ends and further to the first surface layer 8. Therefore the floor frame 7 surrounds the beams 10 in lateral direction.
  • the floor frame 5 may be formed from tubular elements which are joined together by connection pieces 9. Alternatively the load-bearing floor frame 5 may be formed from profile beams such as, I-beam, U-beam or the like.
  • the wall structure 6 may be supported to the upper surface of the floor frame 5. As shown schematically in figure 2B the floor structure further comprises longitudinal gripping part channels 30 arranged to receive a fork of a forklift loader such that the transport container may be lifted and moved with the forklift loader.
  • the support beams 10 and the gripping part channel 30 extend substantially in width direction of the floor structure 2, or substantially transversely to the longitudinal direction of the floor structure 2.
