The bottom frame longitudinal beam unit (11, 12, 13) comprises panels (110, 120, 130) arranged horizontally and first bent edges (111, 121, 131) downward extending from the panels (110, 120, 130). The vertical height of at least one of the first bent edges (111, 121, 131) is no less than 80 mm. The use of the container bottom frame can cancel or greatly reduce the arrangement of conventional bottom beams on the bottom frame, so that the assembly work of the bottom frame is reduced, the efficiency is improved and at the same time the weight of bottom frame is reduced.

Description

Container chassis and assembly method thereof

Technical field

The invention relates to the field of containers, in particular to a container chassis and an assembly method thereof.

Background technique

In order to facilitate the carrying of goods in the container, the CROSS MEMBER has to be set in a fixed mode, and the bottom beam is arranged densely. Generally, the 20-foot box has more than 15 bottom beams, 40 feet. The box has more than 35 bottom beams, and the installation of the bottom beam is cumbersome. In addition, the common dry cargo container chassis, most of which use wooden floor laying on the multiple bottom beams on the chassis, fixes the wooden floor on the chassis by fasteners, which not only requires a large amount of wood, is not conducive to environmental protection, but also Due to the frequent loading and unloading of forklift trucks, wooden floors are easily damaged, thereby shortening their service life and increasing corresponding maintenance costs. Therefore, research on alternative materials for wooden floors is needed to solve the problems of wooden floors.

At present, it is generally considered to use steel flooring instead of wood flooring or partial replacement of wooden flooring. It is still necessary to lay steel flooring on a plurality of bottom beams and fix them by welding or fasteners, but because the steel flooring is assembled differently from wood. Floors, and steel materials have a heavier specific gravity, so the current steel floor container production assembly efficiency is lower, and the weight is heavier than the wood floor container.
