  • the present invention relates to a shipping container, and more particularly, to the improvements on the structure of a container.
  • Containers were first used in cargo transportation in U.S.A. in 1956. After more than 40 years development, containers have been used worldwide. In the course of the development of the container, designers and manufacturers are devoted to improvements on its structure, so as to improve the functions of the container, reduce the material consumed and the production cost.
  • a conventional shipping container consists of a pair of side walls 1 , a rear end 2 , a front end 3 , a roof 4 , a floor 5 and a base frame 6 , where the base frame 6 and the floor 5 constitute the bearer for the cargoes in the container which is also called the base assembly.
  • the conventional container base frame mainly comprises two bottom side rails 601 , numbers of bottom cross members 602 , where the two ends of the bottom cross members 602 are welded to the bottom side rail 601 respectively, constituting a rigid integral frame structure.
  • plywood floor 5 (28 mm) is paved on the bottom cross members 602 , and joined with the bottom cross members 602 by screws 603 , the plywood floor 5 and the base frame 6 make up the bearer for the cargoes in the container.
  • the cross members need to be arranged in high density with quantities of beams, and the bottom cross members should be made of thick steel plates to satisfy the strength requirement, therefore, large quantity of material is consumed.
  • the floor is made of special hard wood.
  • there exist several shortcomings such as: a great diversity in quality, expensive price, high cost, and easily influenced by possible shortage of plywood floor supplies.
  • the plywood floor is heavier in weight, and the tare weight of the container is heavier accordingly.

  • the conventional corrugated structure of the side panels is not advantageous for enhancing the bending resistant capability of the corrugated plate, therefore, thicker steel sheet and high strength material have to be adopted to pass ISO test. Use of high strength material drives up the material cost and use of thicker steel sheet not only increases material cost and tare weight, but also decreases the loading capacity and efficiency.
