Base frame for a shipping container

Abstract

The invention relates to a base frame for a shipping container, comprising a front end and a rear end separated by a bolster, the front end of the base frame comprising a pair of bottom side rails or beams and a pair of gooseneck rails or beams positioned in a longitudinal direction of the container, the rear end of the base frame extending from a door sill to the bolster, where the gooseneck rails extends continuously from a front sill to the bolster and that a number of bows extends continuously from a bottom side rail in one side of the front end of the base frame to a bottom side rail in an opposite side of the front end of the base frame.

Description

[0001]The invention relates to a base frame for a shipping container, the base frame comprising a front end and a rear end separated by a bolster, the front end of the base frame comprising a pair of bottom side rails or beams and a pair of gooseneck rails or beams positioned in a longitudinal direction of the container, the rear end of the base frame extending from a door sill to the bolster.BACKGROUND[0002]A shipping container usually comprises a pair of side walls, a rear end, a front end, a roof, a floor and a base frame. The base frame comprises two longitudinal bottom side rails and a plurality of parallel bottom cross members on which the floor is resting and to which cross members the floor is secured by fastening means. In the end of the floor and base frame placed in the front end of the container a cross member being heavier than the ordinary cross members forms one end of a so called gooseneck area of the container. Such a heavier cross member is often called a bolster. ...

AI Technical Summary

Benefits of technology

The invention provides a base frame with sufficient strength and flexibility to use a flooring system. The flooring elements can be provided as modular flooring elements. By using a steel floor covering the length from the bolster to the front sill and covering the width from a bottom side rail in one side to a bottom side rail in the other side of the container, the need for several different sizes of floor plates is reduced. Additionally, by changing the position of the bolster and the design of the area from bolster to front panel to comprise an all steel structure, the need for traditional outrigger flooring is eliminated. This allows for the use of a module of common dimensions of wooden flooring plates and reduces the required length of the floor panels. This results in a reduced amount of floor board types and simplifies the installation process.

Problems solved by technology

Above dimensions of floor plates hinder the full use of a modular system, since neither length nor width of the two areas are dividable with each other.
